Description

Technical Field

[0001] This utility model relates to the field of brick production technology, and in particular to a brick extrusion device. Background Technology

[0002] Brick materials refer to the raw materials used to make bricks, mainly including clay, shale, coal gangue, fly ash, etc. Clay bricks are made from clay (including shale, coal gangue and other powders) as the main raw material, which is processed, shaped, dried and fired. Extrusion equipment is required to process the material into shape during brick production.

[0003] As shown in the reference case "A Sintered Brick Material Forming Machine" (Announcement No. CN218195847U), the raw materials are screened by a stainless steel mesh on the extrusion screening device, which traps larger hard raw material blocks. At this time, the piston rod is driven by the hydraulic cylinder to extend and retract, and the piston rod pushes the pressure plate into the fixed frame, thereby crushing the larger raw material blocks on the stainless steel mesh. The machine can seal the upper and lower parts together. The crushed raw material extruded by the upper mixing first enters the vacuum chamber and the air in the mud is extracted in the vacuum chamber. Then it is extruded by the lower spiral to become a smooth and dense mud strip. This avoids blockage in the machine and also prevents large raw material blocks from affecting its production during the operation of the brick extruder, thereby improving its working efficiency and production quality.

[0004] According to the above reference materials, the stainless steel mesh on the extrusion screening device in the above-mentioned device screens the raw materials, causing larger hard raw material blocks to be intercepted. At this time, the piston rod is driven by the hydraulic cylinder to extend and retract, and the piston rod pushes the pressure plate into the fixed frame, thereby crushing the larger raw material blocks on the stainless steel mesh. However, when the device is used to produce bricks by extrusion, the large particles in the brick material are not crushed and mixed thoroughly enough, which can easily affect the quality of the brick material, making it inconvenient to effectively extrude the brick material and reducing the processing effect of the brick material. Utility Model Content

[0005] Therefore, it is necessary to provide a brick extrusion device to address the problem of inconvenience in effectively extruding brick materials.

[0006] The device includes a barrel, with a feed box fixedly connected to one end of the top of the barrel and a mold installed at the other end. A mixing mechanism is provided on the inner wall of the feed box. The mixing mechanism includes two extrusion rollers rotatably connected to the top wall of the feed box, a turning roller rotatably connected to the middle of the inner wall of the feed box, a filter plate fixedly connected to the bottom of the inner wall of the feed box, the outer wall of the turning roller being in contact with the inner wall of the filter plate, and an extrusion assembly provided on the inner wall of the barrel.

[0007] In one embodiment, the mixing mechanism further includes a first gear fixedly connected to one end of the extrusion roller, two first gears meshing with each other, and one end of the extrusion roller passing through the feed box and the first gear in sequence.

[0008] In one embodiment, a first motor is mounted on the top of one side of the feed box, and the output shaft of one end of the first motor is fixedly connected to one end of one of the extrusion rollers.

[0009] In one embodiment, one end of the other extrusion roller and one end of the turning roller are both fixedly connected to a drive wheel, and a drive belt is connected between the two drive wheels.

[0010] In one embodiment, the extrusion assembly includes two spiral rods rotatably connected to the inner wall of the barrel, the two spiral rods being interleaved with each other.

[0011] In one embodiment, one end of the screw is rotatably connected to a support ring, and one side of the support ring is fixedly connected to the inner wall of the barrel.

[0012] In one embodiment, one end of each of the two screw rods passes through the barrel and is fixedly connected to a second gear, and the two second gears mesh with each other.

[0013] In one embodiment, a second motor is mounted on one end of the barrel, and the output shaft of one end of the second motor is fixedly connected to one end of one of the screw rods.

[0014] Beneficial effects

[0015] 1. In the above-mentioned brick extrusion equipment, the two extrusion rollers in the feed box can pressurize and crush the particles and lumps in the brick material. The two extrusion rollers are driven to rotate in opposite directions by the first motor and the two first gears, which can crush the brick material. The filter plate can filter the crushed brick material and intercept the residual particles and lumps. The other extrusion roller is driven to rotate by the two drive wheels and the drive belt, which fits against the inner wall of the semi-circular filter plate, which can turn and disperse the brick material and prevent the brick material from clogging on the filter plate. It can disperse and mix the particles and lumps of the brick material and improve the processing quality of the brick extrusion equipment.

[0016] 2. The two screw rods inside the barrel can be driven to rotate in opposite directions by the cooperation of the second motor and the two second gears. The staggered rotation of the two screw rods generates shearing force, which can shear and mix the brick material and extrude the brick material into the mold at one end. This can improve the quality of the finished brick material and improve the performance of the brick extrusion equipment. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The following is combined with Figures 1-5 This invention describes a brick extrusion device.

[0027] In one embodiment, a brick extrusion device includes a barrel 100, a feed box 200 fixedly connected to one end of the top of the barrel 100, a mold 300 installed at the other end of the barrel 100, and a mixing mechanism 400 provided on the inner wall of the feed box 200; wherein, the mixing mechanism 400 includes two extrusion rollers 410 rotatably connected to the inner top wall of the feed box 200, a turning roller 420 rotatably connected to the middle of the inner wall of the feed box 200, a filter plate 430 fixedly connected to the bottom end of the inner wall of the feed box 200, the outer wall of the turning roller 420 being in contact with the inner wall of the filter plate 430, and an extrusion assembly 480 provided on the inner wall of the barrel 100.

[0028] It should be noted that the brick extruder consists of:

[0029] The extrusion and feeding system mainly consists of a feed box 200, a screw 481, and a barrel 100. It plasticizes the raw material into a uniform melt and generates pressure during the process. The screw 481 continuously, at constant pressure, temperature, and quantity extrudes the material through the die head.

[0030] Transmission system: includes electric motor, adjustment device and transmission device. The function of the transmission system is to drive the screw 481 and provide the torque and speed required by the screw during operation.

[0031] Heating and cooling system: Composed of temperature control equipment, it ensures that the extrusion system's molding is carried out within the process requirements by heating and cooling the barrel 100.

[0032] Control system: Composed of electrical components, instruments and actuators, used to regulate and control the rotational speed of the screw 481, the temperature of the barrel 100, the pressure of the head, etc.

[0033] Mold 300: Used to shape brick materials.

[0034] During brick extrusion, the two extrusion rollers 410 inside the feed box 200 can crush and pulverize large particles and lumps in the brick material. The turning roller 420, in conjunction with the filter plate 430, can mix the brick material while simultaneously breaking down any remaining particles. Finally, the two screw rods 481 inside the barrel 100 convey and extrude the brick material. This process optimizes the processing effect of the brick extruder without affecting its normal operation.

[0035] like Figure 2 and Figure 3As shown, the mixing mechanism 400 also includes a first gear 440 fixedly connected to one end of the extrusion roller 410. The two first gears 440 mesh with each other. One end of the extrusion roller 410 passes through the feed box 200 and the first gear 440 in sequence. A first motor 450 is installed on the top of one side of the feed box 200. The output shaft of one end of the first motor 450 is fixedly connected to one end of one of the extrusion rollers 410. One end of the other extrusion roller 410 and one end of the turning roller 420 are both fixedly connected to a transmission wheel 460. A transmission belt 470 is connected between the two transmission wheels 460.

[0036] In this embodiment, the two extrusion rollers 410 inside the feed box 200 are driven by the first motor 450 driving the two first gears 440 to mesh with each other. The two extrusion rollers 410 rotate in opposite directions to crush the particles and lumps in the brick material, thereby improving the raw material quality of the brick material. After crushing, the brick material falls onto the filter plate 430 to intercept the remaining particles and lumps. The turning roller 420 rotates in cooperation with the two drive wheels 460 and the drive belt 470 to turn and disperse the brick material on the filter plate 430 and prevent the brick material from clogging on the filter plate 430. The brick material can be conveyed into the barrel 100, which can effectively crush and mix the brick material particles and lumps, thereby improving the processing quality of the brick extruder.

[0037] like Figure 4 and Figure 5 As shown, the extrusion assembly 480 includes two spiral rods 481 rotatably connected to the inner wall of the barrel 100. The two spiral rods 481 are interleaved. One end of each spiral rod 481 is rotatably connected to a support ring 482. One side of the support ring 482 is fixedly connected to the inner wall of the barrel 100. One end of each spiral rod 481 passes through the barrel 100 and is fixedly connected to a second gear 483. The two second gears 483 mesh with each other. A second motor 484 is installed at one end of the barrel 100. The output shaft of one end of the second motor 484 is fixedly connected to one end of one of the spiral rods 481.

[0038] In this embodiment, when the crushed and mixed brick material falls into the barrel 100, the second motor 484 can drive the two screw rods 481 to rotate in opposite directions through the meshing of two second gears 483. This can shear and mix the brick material and extrude it into the mold 300, effectively extruding the brick material and improving the quality of the finished brick material.

[0039] Working principle: Brick material enters through the feed box 200 and falls onto two extrusion rollers 410. The control system drives the first motor 450 to run, which in turn drives one of the first gears 440 to mesh with the other. The two first gears 440 drive the two extrusion rollers 410 to rotate and extrude and crush the brick material, causing it to fall onto the filter plate 430. When the other extrusion roller 410 rotates, it drives the turning roller 420 to rotate through the two transmission wheels 460 and the transmission belt 470, turning the brick material in the filter plate 430 and breaking up any remaining granular clumps. The brick material falls into the barrel 100 through the filter plate 430. The control system drives one of the second gears 483 to mesh with the other, which in turn drives the two screw rods 481 to rotate and extrude the brick material into the mold 300.

[0040] It should be noted that the first motor 450 and the second motor 484 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the first motor 450 and the second motor 484 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this 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 of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
