[0002] Steam concrete block is a kind of light building material, is widely used in construction industry. When pouring steam -cured aerated concrete block, material slurry is directly discharged from mixing tank, directly pours into mould after adjusting valve. Since material slurry itself has certain viscosity, so the pipeline of discharging material is relatively wide to facilitate the discharge of material slurry, and can also prevent material slurry from blocking pipeline. Also because of the above-mentioned condition limit, it leads to that the impact inertia of material slurry is relatively large when being poured into mould, impact pit is formed, and the material slurry around impact pit collapses and flows into impact pit, which also makes a large amount of air bubble be poured into the inside of material slurry, so the mould after pouring needs to be vibrated, and large air bubble is scattered and discharged, so how to solve the air bubble generated during pouring has been the problem needing to be solved in the process of material slurry pouring of steam -cured aerated concrete block.

DETAILED DESCRIPTION
[0023] In order to better understand the technical content of the present application, specific embodiments are provided below, and the present application is further described in conjunction with the drawings.
[0024] Referring to Figs. 1 to 3 A steam pressure aerated concrete block slurry casting device, comprising a rack 1 and a transfer box 2 arranged on the rack 1. The top of the transfer box 2 is provided with a push auger 6, and the top of the transfer box 2 is provided with a feed inlet 7. The bottom of the push auger 6 is connected to the feed inlet 7, and the push auger 6 is provided with a connecting pipe 4.
[0025] It should be particularly noted that the push auger 6 is a screw conveyor device for pushing material. The screw conveyor device is a commonly used quantitative conveying device in the prior art, mainly including a push auger pipe, a push auger screw shaft arranged in the push auger pipe, and a push auger motor for driving the push auger screw shaft to rotate. The 'push auger pipe', 'push auger screw shaft' and 'push auger motor' in the above expression do not indicate that these components are specially designed, but only for differentiation from'screw shaft' and'motor 14' in the following. Those skilled in the art can use any screw conveyor device with the above functional components to realize the function of the push auger 6 in the present disclosure.
[0026] The bottom of the transfer box 2 is also provided with a plurality of spaced-apart casting pipes 11, and the inner diameter of the casting pipe 11 is smaller than the inner diameter of the push auger 6 (the inner diameter of the push auger 6 here refers to the inner diameter of the pipe of the push auger 6).
[0027] Preferably, the total internal cross-sectional area of all the casting pipes 11 is equal to the cross-sectional area of the push auger pipe.
[0028] The screw shaft is arranged in the pouring pipe 11, and the screw shaft comprises a rotating shaft 9 and a spiral blade 10 arranged on the outer wall of the rotating shaft 9. The spiral blade 10 is arranged in the entire pouring pipe 11 and extends upwards into the transfer box 2. The top of the rotating shaft 9 is arranged in the top wall of the transfer box 2 and extends upwards. The top of the rotating shaft 9 is connected to the transmission mechanism, so that the screw shaft rotates in the pouring pipe 11.
[0029] When the above scheme is used, the discharge pipe of the stirring tank is connected to the connecting pipe 4 of the pushing auger 6. After the slurry is connected to the pushing auger, the output efficiency of the slurry can be effectively controlled by the pushing auger. According to the output rate of the pushing auger and the volume of the required slurry, the pushing time of the pushing auger for each pouring mold is calculated.
[0030] When the slurry enters the transfer box 2, the slurry is a viscous fluid, so when it encounters the reduced-diameter pouring pipe 11, it is difficult to flow quickly downward through the pouring pipe 11 by itself. At this time, the spiral shaft can effectively control the downward flow rate of the slurry.
[0031] In specific operation, the mold is placed on the lifting device, and the mold is lifted to be arranged below the pouring pipe 11, so that the bottom of the pouring pipe 11 is close to the bottom of the mold. When the pushing auger 6 starts to push the slurry into the transfer box 2, the motor 14 is started synchronously. The motor 14 drives the rotating shaft 9 to rotate, which drives the spiral blade 10 in the pouring pipe 11 to rotate. The spiral blade 10 rotates to continuously press the slurry in the transfer box 2 into the pouring pipe 11. Because the pouring pipe 11 is small, compared with the slurry directly discharged from the large-diameter discharge pipe of the stirring tank in the traditional pouring process, the weight of the slurry discharged from the pouring pipe 11 in the same unit time is smaller, thereby reducing the impact inertia of the slurry during discharging, and the slurry is discharged at a constant speed, thereby reducing the size of the impact pit and even avoiding the appearance of the impact pit, so as to avoid a large number of bubbles being brought into the slurry.
[0032] It should be particularly noted that the lifting device for controlling the lifting of the mold is a commonly used technical means in the production field, and the lifting device is not within the improvement range of the present disclosure, so the lifting device does not need to be specifically described.
[0033] By arranging the pushing auger, cooperating with the smaller-diameter pouring pipe 11 and the spiral shaft, the pouring amount of the slurry is changed from large to small, the problem of the difficulty of the flow of the viscous slurry after the pouring amount is changed from large to small is solved, the overall pouring efficiency can be ensured within a reasonable range, and the overall pouring amount can be controlled by the pushing auger and the spiral shaft of the pouring pipe 11.
[0034] Specifically, the pushing auger 6 is also arranged in an inclined manner through the support 5, so that the pipeline for pushing and stirring is inclined.
[0035] When the above scheme is used, the slurry can flow into the transfer box 2 more easily by setting the inclined pushing auger 6, and the running power of the motor 14 of the pushing auger 6 is reduced.
[0036] Specifically, the transmission mechanism comprises the motor 14 fixed to the top of the transfer box 2, and a driving wheel 13 is arranged on the output shaft of the motor 14. The transmission mechanism further comprises a plurality of transmission wheels 12, and the plurality of transmission wheels 12 are fixedly sleeved on the rotating shafts 9. A plurality of transmission wheels 12 are arranged on each rotating shaft 9, and the transmission wheels 12 on the plurality of rotating shafts 9 form a transmission wheel 12 system. The transmission wheel 12 system is in driving connection with the driving wheel 13 of the motor 14.
[0037] When the above scheme is used, the driving wheel 13 and the transmission wheels 12 are all belt wheels, the transmission wheels 12 are in transmission with each other through belts, and one of the transmission wheels 12 is in transmission with the driving wheel 13 through a belt, so as to form the transmission wheel 12 system.
[0038] Specifically, the transfer box 2 is a cuboid box body, and the plurality of pouring pipes 11 are evenly arranged in a rectangular array at the bottom of the transfer box 2.
[0039] When the above scheme is used, since the molds of autoclaved aerated concrete blocks are mostly cuboids, the cuboid box body is designed to facilitate the arrangement of the pouring pipes 11, so that the pouring pipes 11 can be evenly distributed in the molds during pouring, and the uniformity of the distribution of the slurry during pouring is improved.
[0040] Specifically, a conical guide plate 3 is further arranged on the inner bottom wall of the transfer box 2, the conical guide plate 3 and the inner bottom wall of the transfer box 2 jointly form a square pyramid, the top of the square pyramid is arranged at the center of the transfer box 2, the feeding port 7 is arranged directly above the top of the square pyramid, a plurality of discharge ports 15 corresponding to the positions of the pouring pipes 11 are arranged on the conical guide plate 3, and the top of each pouring pipe 11 is connected with a discharge port 15.
[0041] When the above scheme is used, the square pyramid is formed by arranging the conical guide plate 3, and the feeding port 7 and the top of the square pyramid are arranged at the center of the transfer box 2, so that the slurry poured into the transfer box 2 can quickly and uniformly fill the transfer box 2, and the pouring pipes 11 located at the periphery of the bottom of the transfer box 2 can also quickly obtain the slurry.
[0042] Specifically, a plurality of rotating shafts 9 in the same column form a transmission group, the number of the motors 14 is the same as the number of the transmission groups, the transmission wheels 12 on the rotating shafts 9 in the same transmission group form a transmission wheel 12 system, and one transmission wheel 12 system is in driving connection with the driving wheel 13 of one motor 14.
[0043] When the above scheme is used, the transmission wheels 12 of the same column of rotating shafts 9 form a transmission wheel 12 system, and a motor 14 is arranged, so that the rotating shafts 9 can all obtain sufficient power, the size of the motor 14 is reduced, and the whole device is convenient to install and arrange.
[0044] Specifically, the top of the transfer box 2 is further provided with an exhaust pipe 8.
[0045] When the above scheme is used, the exhaust pipe 8 is arranged, so that the air squeezed when the slurry is filled into the transfer box 2 can be quickly discharged.
[0046] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
