| A composition for and a method of promoting the flow of a concrete slurry through a pump and a conduit is provided. The composition is a dry particulate mixture comprised of a water soluble, inorganic material and a solvatable, organic polymer. The composition, when mixed with a suitable quantity of water, is useful in a method of priming a pump used to pump a concrete slurry. The composition, when mixed with a concrete slurry, is useful to improve the flow of the slurry through a conduit. | ||||||

| A lock apparatus for introducing granular dry material into a pneumatic conveying conduit (32), for example of a concrete gun, consisting of a material feeding hopper (4) having a shut-off valve (6) actuable by a pneumatic working cylinder (8). Beneath the shut-off valve (6) two hose portions (16 and 22) are arranged in series and on each of said portions a hose squeezing means (34 and 38) engages between which the hose portions (16 and 22) form a lock chamber (44) which is additionally provided with a blowing air connection (62). By the shut-off valve (6) and the upper hose squeezing means (34) an antechamber (42) is formed. When the upper hose squeezing means (34) is closed and the shut-off valve (6) opened the antechamber (42) is filled from the feeding hopper (4) by free fall. At the same time the lock chamber (44) can be discharged into the blow conduit (32) by opening the hose squeezing means (38). The uppermost (6) and lowermost (38) shut-off members then close again and by opening the upper hose squeezing means (34) the contents of the antechamber (42) are discharged into the lock chamber (44). The hose squeezing means (34 and 38) operate against an empty hose. The sole material-contacted shut-off member is the shut-off valve (6). The apparatus otherwise comprises no wearing sealing parts. | ||||||

| A rotor (1) of a machine for spraying concrete, mortar or a refractory lining material comprises conveying chambers (11') arranged concentrically around its axis, and delimited by cylindrical walls (11) of a porous, air-permeable material, the inside of the walls (11) being machined smooth. Each cylindrical wall (11) is surrounded by an air chamber (10), each of which is acted upon, between a charging point (26) and a discharge point (27), by the pressure of a compressed air source (32) so as to produce air flows which pass through the porous walls (11) into the conveying chambers (11'). The material to be conveyed by the conveying chambers (11') between the charging point (26) and the discharge point (27) is at least in the regions close to the wall acted upon by these air flows so as to prevent the material from adhering to the chamber walls (11'). The discharge through the discharge opening (27) into a conveying line (30) takes place essentially by gravity and by the action of an injector nozzle (31). Since the air flows supplied through the chamber walls (11) are only small, the action of the injector nozzle (21) is not disturbed by compressed air surges, so that a uniform conveying of the material through the conveying line (30) is possible. | ||||||

| One of ingredients of green concrete are supplied to a rotary disc through a central tube by a pump or low pressure air and the other ingredient is supplied to the rotary disc from a hopper by a screw conveyor. These ingredients are mixed together on a rotary disc and then projected by centrifugal force. | ||||||

| A flexible hose for transport of concrete and the like includes a hardened helical wire to prevent collapse under negative pressure and bending of the hose. The hose is provided with an end coupling having a hardened inner shank with the outer surface serrated or the like to provide firm interengagement with the inner hose surface grooved for interconnection by the conventional releasable coupler. The hose end is specially processed to remove the hardness from the helical wire. The hose may be abraded adjacent the location of the inner end of the shank and a current passed through the end portion of the wire. The hose is forced over the shank and an outer clamp device forces the hose with the soft helical wire onto the shank and firmly affixes the hardened shank to the hose.

| PURPOSE: A concrete placing apparatus is provided to effectively place concrete in a high-rise building by minimizing the vertical transfer distance of the concrete using multiple conveyors. CONSTITUTION: A concrete placing apparatus comprises multiple conveyor units(10), a concrete tank(20), and a pumping unit. The conveyor units are spirally installed in a vertical mast(2) of a tower crane(1) and convey concrete. The concrete tank is connected to the uppermost conveyor unit and receives concrete from the uppermost conveyor unit. The pumping unit sends concrete stored in the concrete tank to a concrete placing position. | ||||||

| 콘크리트 흐름에 압축공기와 응고촉진제를 혼합하고 이것을 노즐로 보내고 농축해서 규격에 맞는 콘크리트를 혼합노즐로 분사하는 습식분사방식용 콘크리트 펌프에 관해 본 발명은, 한편으로는 노즐에서 분진탈락을 최소화하고 다른 한편으로는 습식분사 방식용 필요압축 공기량을 공급하도록 하는 첫번째 일처리를 조절기(20)에서 표시되도록 하며, 이 조절기는 콘크리트펌프(1)의 콘크리트처리량(이동량), 압축공기가 흐르는 혼합노즐(3)의 양조절에 필요한 공급크기(소요량)를 단위시간 마다 분사되는 콘크리트에 대한 단위시간 마다 혼합되는 압축공기량의 실제값의 비율이 규격치에 일치하도록 하는 방식으로 설정하는데 이 비율은 콘크리트 처리과정에서 제일 적은 양의 분진탈락이 발생하는 비율이다. | ||||||
| 38 | Pipeline Conveyor Systems | US13577275 | 2011-01-19 | US20130011209A1 | 2013-01-10 | Ian D. Doig |
| A pipeline (500) equipped with at least one pump (400) transports granules dispersed in a carrier fluid in intervals between co-transported pigs in a pipeline. Each pump and each pig is configured to preserve the intervals between pigs, and the orientation of the pigs, during passage of the pigs and granules through each pump. Also, each pig may comprise peripheral apertures providing a leakage of carrier fluid into the intervals downstream of each pig as a means of preserving the dispersion of granules within the pipeline. In the example shown granules are introduced to the pipeline by inlet feed hopper (400), and granules are removed from the pipeline at outlet delivery hopper 650. Hopper 404 introduces pigs at the pipeline inlet and hopper 652 removes pigs at the pipeline outlet: pigs are returned to hopper (404) by the pipeline (500A). | ||||||

| The invention relates to a transport tube for thick materials, in particular for concrete. The transport tube comprises substantially a pressure tube (16) from wear-resistant tube material, which is preferably hardened on the inside, and at least one coupling ring (18′, 18″) which is fixed with a material-to-material fit at the end to the outer face of the pressure tube (16). According to the invention, the coupling ring (18′, 18″) has a first ring part (34) having an inner face of excess dimensions with respect to the outer face of the pressure tube (16), and a second ring part (36) which adjoins the first ring part (34) axially and has an inner cone which deviates in its axial profile from the outer face of the pressure tube (16) as far as an undersize. The coupling ring (18′, 18″) is pressed onto the outer face of the pressure tube (16) with the inner cone (38) of its second ring part (36). Furthermore, it delimits an annular gap space (40) with its first ring part (34) together with the pressure tube (16), which annular gap space (40) is filled at least partially with an adhesive to produce the material-to-material connection. | ||||||

| A concrete rebound shield and method of use is disclosed. The concrete rebound shield includes a bell defining an opening adapted to receive a feed hose. A collar nests within the opening of the bell and attaches to the feed hose such as to retain the bell onto the feed hose. The bell is adapted to substantially surround the feed hose and direct hydrated concrete toward a selected area. | ||||||
