Description

A steam-pressurized concrete block production casting device Technical Field

[0001] This utility model relates to the field of casting device technology, and in particular to a casting device for producing steam-pressurized concrete blocks. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are a lightweight, porous new type of building material. They are characterized by their light weight, good thermal insulation, strong sound insulation, and excellent fire resistance. They are mainly composed of siliceous materials (such as sand and fly ash) and calcareous materials (such as cement and lime), with aluminum powder as the gas-generating agent. The process involves batching, pouring, gas expansion, cutting and shaping, and finally autoclaving.

[0003] During the pouring process, there are different distances between the outlet of the grouting tank and the molds at different depths. As the grout level in the mold rises, the continuously falling grout will splash out of the mold. The grout solidifies around the mold and is not easy to clean, resulting in grout waste and thus a decrease in the compatibility between the grouting tank and different molds. Summary of the Invention

[0004] The purpose of this utility model is to provide a steam-pressurized concrete block production casting device to solve the problem that the continuously falling grout is prone to splashing out of the mold due to the different distances between the grouting tank outlet and the mold at different depths.

[0005] This utility model provides a casting device for producing steam-pressurized concrete blocks, including a grouting tank, wherein the discharge end of the grouting tank is equipped with a discharge hopper, and the casting device includes:

[0006] A casting pipe, wherein the inlet end of the casting pipe is connected to the discharge hopper, and an extension pipe is inserted into the outer periphery of the casting pipe;

[0007] The flow divider shell is connected to the discharge end of the extension tube. The extension tube drives the flow divider shell to extend into the cavity of the external mold to shorten the falling distance of the slurry. Both ends of the flow divider shell are provided with slurry outlets, which are used for bidirectional discharge of the flow divider shell.

[0008] The telescopic component has a mounting plate fixedly connected to its top end, which is fixedly connected to the pouring pipe. A connecting rod is fixedly connected to the output end of the telescopic component, and the bottom end of the connecting rod is fixedly connected to the diversion shell.

[0009] Preferably, both ends of the diversion shell are provided with guide shells, which are connected to the diversion shell by bolts. The guide shells are used to adjust the discharge position of the slurry.

[0010] Preferably, a cleaning component is provided in the slurry outlet, and the cleaning component is used to clean the slurry outlet;

[0011] The cleaning assembly includes:

[0012] A support base, the top of which is connected to the mounting plate via a connector;

[0013] Two flange joints are symmetrically distributed based on the support base. A water spray pipe is rotatably connected to the inner cavity of each flange joint and extends to the slurry outlet to clean the slurry outlet.

[0014] A rotating component, which drives the water spray pipe to rotate.

[0015] Preferably, the rotating component includes:

[0016] An electric actuator, the top end of which is fixedly connected to the support base;

[0017] A rack plate is fixedly connected to the output end of the electric push rod. A gear is meshed with the outer wall of the rack plate, and the central hole of the gear is fixedly connected to the outer periphery of the water spray pipe.

[0018] Preferably, the connector includes:

[0019] Two sliding rods, one end of each sliding rod is fixedly connected to the support base, and the other end of each sliding rod is inserted into a cylinder, which is fixedly connected to the mounting plate;

[0020] The cylinder is connected to the slide rod via a locating pin.

[0021] Preferably, the two slide bars are symmetrically distributed based on the support base.

[0022] Preferably, the telescopic component is a cylinder.

[0023] Preferably, the hopper is machined with a conical groove so that the slurry can be collected into the casting pipe.

[0024] Preferably, the pouring pipe is equipped with a solenoid valve, which is used to control the opening and closing of the pouring pipe.

[0025] Preferably, the outer wall of the diversion shell is uniformly distributed with threaded holes, which are adapted to the bolts.

[0026] This utility model provides a casting device for the production of steam-pressurized concrete blocks:

[0027] By using the casting pipe, extension pipe, diversion shell, slurry outlet, and expansion joint in combination, the output end of the expansion joint drives the connecting rod to move downward, and the connecting rod drives the diversion shell to move downward into the inner cavity of the molding mold. By changing the discharge height of the grouting tank, slurry splashing is prevented, and the splashed slurry is prevented from solidifying around the mold and being difficult to clean, thus reducing slurry waste. The slurry in the grouting tank enters the diversion shell through the casting pipe. The slurry is diverted in the diversion shell and converges into the molding mold along the slurry outlet. The design of the double-sided slurry outlet disperses the discharge direction of the slurry. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this embodiment, as shown in Figures 1 and 2, a steam-pressurized concrete block production casting device includes a grouting tank 1, with a discharge hopper 11 at the discharge end of the grouting tank 1. The casting device includes a casting pipe 2, with the inlet end of the casting pipe 2 connected to the discharge hopper 11, and an extension pipe 21 inserted into the outer periphery of the casting pipe 2; a diversion shell 3, with the discharge end of the diversion shell 3 connected to the discharge end of the extension pipe 21, the extension pipe 21 driving the diversion shell 3 to extend into the cavity of the external mold to shorten the falling distance of the grout, and grout outlets 31 are provided at both ends of the diversion shell 3 for bidirectional discharge of the diversion shell 3; and a telescopic component 4, with an installation plate 41 fixedly connected to the top end of the telescopic component 4, the installation plate 41 being fixedly connected to the casting pipe 2, and a connecting rod 42 fixedly connected to the output end of the telescopic component 4, the bottom end of the connecting rod 42 being fixedly connected to the diversion shell 3.

[0041] Thus, the external molding mold is moved to the bottom of the grouting tank 1, and the output end of the telescopic component 4 drives the connecting rod 42 to move downward. The connecting rod 42 drives the diversion shell 3 to move downward into the inner cavity of the molding mold. By changing the discharge height of the grouting tank 1, splashing of grout is prevented. At the same time, the extension pipe 21 moves downward along the outer wall of the casting pipe 2 with the diversion shell 3. Then, the grout in the grouting tank 1 enters the diversion shell 3 through the casting pipe 2. The grout is diverted in the diversion shell 3 and gathers into the molding mold along the grout outlet 31. The design of the double-sided grout outlet 31 disperses the discharge direction of the grout.

[0042] Specifically, the hopper 11 is used to connect the pouring pipe 2 and the grouting tank 1. The grouting tank 1 is fixed by an external device and there is a certain distance between it and the bottom surface. The diversion shell 3 is a hollow rectangular body and is connected to the extension pipe 21. The diversion shell 3 is used to fill the slurry into the external molding mold. The mounting plate 41 is used to support the telescopic component 4. The design of the connecting rod 42 is used to extend the working length of the output end of the telescopic component 4 and prevent the output end of the telescopic component 4 from entering the slurry in the molding mold.

[0043] In some embodiments, as shown in Figures 2 and 3, both ends of the diversion shell 3 are provided with guide shells 32. The guide shells 32 are connected to the diversion shell 3 by bolts 33 and are used to adjust the discharge position of the slurry.

[0044] Specifically, the guide shell 32 is U-shaped and is detachably connected to the diversion shell 3. The guide shell 32 can be used in groups or independently. The guide shell 32 can be used to transfer slurry to different positions of the molding die.

[0045] In some embodiments, as shown in FIG4, a cleaning assembly 5 is disposed in the slurry outlet 31. The cleaning assembly 5 is used to clean the slurry outlet 31. The cleaning assembly 5 includes: a support base 51, the top end of which is connected to a mounting plate 41 via a connector 52; two flange joints 53, which are symmetrically distributed based on the support base 51. A water spray pipe 531 is rotatably connected to the inner cavity of the flange joint 53. The water spray pipe 531 extends into the slurry outlet 31 to clean the slurry outlet 31; and a rotating member 54, which is used to drive the water spray pipe 531 to rotate.

[0046] Specifically, the support base 51 is used to support the two flange joints 53. The water spray pipe 531 is connected to the flange joint 53 through a sealed bearing. Multiple water outlets are evenly distributed on the outer periphery of the water spray pipe 531. The two water spray pipes 531 can extend into the diversion shell 3 at the same time to clean the slurry outlet 31.

[0047] It should be noted that the water spray pipe 531 is used to clean the slurry outlet 31, reducing slurry residue and preventing slurry accumulation at the slurry outlet 31 from causing blockage.

[0048] In some embodiments, as shown in Figures 5 and 6, the rotating member 54 includes: an electric push rod 541, the top end of which is fixedly connected to a support base 51; a rack plate 542, which is fixedly connected to the output end of the electric push rod 541, and a gear 543 is meshed with the outer wall of the rack plate 542, the center hole of the gear 543 being fixedly connected to the outer periphery of the water spray pipe 531.

[0049] Specifically, the electric push rod 541 is used to drive the rack plate 542 to move vertically. The gear 543 is designed to have two parts, which are respectively connected to the two water spray pipes 531. Through the cooperation of the rack plate 542 and the gear 543, the water spray pipes 531 are driven to rotate, so as to thoroughly clean the slurry outlet 31.

[0050] In some embodiments, as shown in FIG5, the connector 52 includes: two slide rods 521, one end of each slide rod 521 being fixedly connected to the support base 51, and the other end of each slide rod 521 being inserted into a cylinder 522, the cylinder 522 being fixedly connected to the mounting plate 41; the cylinder 522 is connected to the slide rod 521 by a positioning pin 523.

[0051] Specifically, the number of cylinders 522 used is the same as the number of slide rods 521 used. The outer wall of the positioning pin 523 is machined with threads. The positioning pin 523 is used to fix the position of the slide rod 521 in the cylinder 522.

[0052] In some embodiments, as shown in FIG5, the two slide rods 521 are symmetrically distributed based on the support base 51;

[0053] Specifically, the design of the two slide bars 521 facilitates the horizontal movement of the support base 51 and increases the load-bearing capacity of the support base 51.

[0054] In some embodiments, as shown in FIG3, the telescopic component 4 is a cylinder;

[0055] Specifically, the telescopic component 4 adopts a cylinder design, which facilitates the adjustment of the working height of the diverter shell 3. In addition, the telescopic component 4 can also be replaced by other telescopic structures.

[0056] In some embodiments, as shown in FIG3, the hopper 11 is machined with a conical groove so that the slurry can be collected into the casting pipe 2.

[0057] Specifically, the conical groove design in the hopper 11 facilitates the collection of slurry into the casting pipe 2 for auxiliary feeding.

[0058] In some embodiments, as shown in FIG3, the casting pipe 2 is equipped with a solenoid valve 22, which is used to control the opening and closing of the casting pipe 2.

[0059] Specifically, the design of the solenoid valve 22 facilitates the electric control of the opening and closing of the pouring pipe 2, which is beneficial for controlling the amount of slurry poured.

[0060] In some embodiments, as shown in FIG3, the outer wall of the diversion shell 3 is uniformly distributed with threaded holes, which are adapted to the bolts 33.

[0061] The guide shell 32 can be used selectively. The design of evenly distributed threaded holes makes it easy for the bolts 33 to fix the guide shell 32 at different positions of the diversion shell 3, so as to facilitate the transfer of slurry from the guide shell 32 to different positions of the forming mold.

[0062] The working principle of this application is illustrated below with a preferred embodiment:

[0063] The external molding mold is moved to the bottom of the grouting tank 1, and then the telescopic component 4 is activated. The output end of the telescopic component 4 drives the connecting rod 42 to move downward. The connecting rod 42 drives the diversion shell 3 to move downward into the inner cavity of the molding mold. At the same time, the extension pipe 21 moves downward along the outer wall of the pouring pipe 2 with the diversion shell 3, and the solenoid valve 22 is opened. Then the grout in the grouting tank 1 enters the diversion shell 3 through the pouring pipe 2. The grout is diverted in the diversion shell 3 and gathers in the molding mold along the grout outlet 31. As the liquid level of the grout in the molding mold continues to rise, the output end of the telescopic component 4 gradually resets. When the liquid level of the grout reaches three-quarters of the depth of the molding mold, the injection of grout stops.

[0064] After the output end of the telescopic component 4 is fully reset, the slurry outlet 31 and the water spray pipe 531 are aligned. After removing the molding die, the slide rod 521 is moved in the cylinder 522. The slide rod 521 moves along the cylinder 522. At the same time, the slide rod 521 drives the support base 51 to move, and then the water spray pipe 531 is inserted into the slurry outlet 31. The position of the slide rod 521 in the cylinder 522 is fixed by the positioning pin 523. The external water source is connected by the flange joint 53. The water source is sprayed into the slurry outlet 31 through the water spray pipe 531. Then, the electric push rod 541 is started. The output end of the electric push rod 541 drives the rack plate 542 to move. The downward movement of the rack plate 542 drives the gear 543 to rotate. Then, the gear 543 drives the water spray pipe 531 to rotate in the flange joint 53. The water source rotates and sprays into the slurry outlet 31 to clean the slurry outlet 31.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
