Technical Field
[0001] This utility model relates to the field of hollow brick manufacturing technology, specifically a dust removal device for the manufacturing of coal gangue hollow bricks. Background Technology
[0002] Coal gangue energy-saving hollow bricks use coal gangue or fluidized bed slag discharged from coal mines as the main raw materials. They not only save land but also consume mine waste. They are an environmentally friendly low-carbon building material. After the coal gangue energy-saving hollow bricks are sintered, a large amount of dust and slag will remain on the finished bricks, which need to be removed by dust removal equipment.
[0003] According to the authorized patent "CN115971119A", a dust removal device for the manufacturing of hollow coal gangue bricks includes a dust removal box, a conveying mechanism, and a through-hole dust removal mechanism. The conveying mechanism is inserted into the dust removal box through material inlets on both sides. At least two fans are fixedly installed on the top inner side of the dust removal box. The through-hole dust removal mechanism is movably arranged inside the dust removal box and is located below the conveying mechanism. When the hollow brick moves to a specific position directly above the through-hole dust removal mechanism, the conveying mechanism stops running, and the through-hole dust removal mechanism moves upward, passes through the conveying mechanism, and reaches the through-hole of the hollow brick to clean the through-hole of the hollow brick. The through-hole dust removal mechanism includes a support, a wind box, a hollow shaft, an air pump, and a transmission device. The wind box is fixedly mounted on the support. The hollow shaft is vertically arranged and rotatably mounted on the wind box through a sealed bearing. A brush cloth is fixed above the hollow shaft, and a flow hole for connecting to the ventilation box is opened on the hollow shaft.
[0004] While the larger dust collection hoods in the above-mentioned technical solutions expand the collection range to some extent, they are fixedly installed above the brick-making machine and cannot be flexibly adjusted according to the changes in the location of dust generation at different production stages. For the collected dust-laden gas, the filtration effect and maintenance convenience of traditional filtration devices also have serious problems. The commonly used ordinary filter screens have low filtration accuracy and cannot effectively intercept a large number of fine particles in coal gangue dust, resulting in a large amount of dust being directly emitted into the atmosphere without sufficient filtration, seriously polluting the surrounding environment.
[0005] Therefore, this utility model provides a dust removal device for the manufacturing of hollow coal gangue bricks. Utility Model Content

Positioning holes are opened in the inner walls on both sides of the sealing plate. A connecting plate is fixedly connected to the outside of the dust collection box. A movable pipe is fixedly connected to the outside of the connecting plate. A snap-fit rod is movably connected inside the movable pipe. A compression spring is fixedly connected to the snap-fit rod. An air outlet pipe is fixedly connected to the outside of the dust collection box.
[0010] Preferably, the air inlet pipe and the suction plate are located inside the brick making machine at the top, and the length of the suction plate is the same as the width of the inside of the brick making machine.

[0015] Beneficial effects
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] (1) In the dust removal device of the coal gangue hollow brick manufacturing, the dust collection mechanism has a blower working through the air inlet pipe and the suction plate. The length of the suction plate is the same as the width of the brick making machine and it is located at the top. It can collect the dust generated during the brick making process over a large area, greatly improve the dust collection efficiency, reduce the dust in the workshop, and improve the working environment. The motor drives the lead screw to rotate, and the collar moves on the lead screw. Through the connecting rod, it drives the suction plate to move left and right, flexibly adjusts the position of the suction plate, accurately collects dust, and improves the dust collection effect.
[0018] (2) In the dust removal device for the manufacturing of hollow coal gangue bricks, a filter plate is installed in the dust collection box of the filtration mechanism. The dust-laden gas sucked in by the dust suction mechanism is introduced into the dust collection box through the pipe. After being filtered by the filter plate, the clean gas is discharged from the outlet pipe, which effectively intercepts dust, reduces dust emissions, and meets environmental protection requirements. The sealing plate on the top of the filter plate is connected to the dust collection box through positioning holes and snap-fit rods. The compression spring assists in fixing it. When cleaning or replacing the filter plate, the snap-fit rod can be pressed to easily remove the filter plate. The operation is simple and reduces maintenance difficulty and cost.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4 A dust removal device for manufacturing hollow coal gangue bricks includes a base 1, a brick making machine 2 fixedly connected to the top of the base 1, a controller 3 on the outside of the brick making machine 2, and a dust collection mechanism 4 on the brick making machine 2.
[0026] The dust collection mechanism 4 includes a power supply box 41, an exhaust fan 42 fixedly connected to the outside of the power supply box 41, an air inlet pipe 43 fixedly connected to the outside of the exhaust fan 42, a suction plate 44 fixedly connected to the bottom of the air inlet pipe 43, a motor 45 fixedly connected to the outside of the brick making machine 2, a lead screw 46 fixedly connected to the output end of the motor 45, a collar 47 threadedly connected to the outside of the lead screw 46, a connecting rod 48 fixedly connected to the bottom of the collar 47, a sliding rod 49 fixedly connected to the outside of the suction plate 44, and a sliding groove 410 opened on the inner wall of the brick making machine 2.
[0027] Furthermore: the air inlet pipe 43 and the suction plate 44 are located inside the brick making machine 2, and the length of the suction plate 44 is the same as the width inside the brick making machine 2. The lead screw 46 is rotatably connected inside the brick making machine 2. The bottom of the connecting rod 48 is fixedly connected to the top of the suction plate 44. The slide rod 49 is symmetrically distributed on the outside of the suction plate 44, and the end of the slide rod 49 away from the suction plate 44 is slidably connected to the inside of the slide groove 410.
[0028] It should be noted that the power supply box 41 integrates an intelligent power monitoring and control module. This module can monitor the power consumption of the exhaust fan 42 and the motor 45 in real time, including parameters such as current, voltage, and power. By analyzing this data, the module can automatically adjust the output power to ensure that the equipment operates efficiently while avoiding damage caused by overload or undervoltage. For example, when the exhaust fan 42 runs under high load for a long time, the power supply box 41 can automatically increase the power supply to ensure the ventilation effect; when the speed of the motor 45 is adjusted, the power supply box 41 can accurately match the corresponding power, improve energy utilization efficiency, and reduce energy consumption.
[0029] Specifically, the exhaust fan 42 adopts a high-efficiency and energy-saving impeller design. The impeller is made of high-strength, corrosion-resistant alloy material. This impeller not only generates strong suction to meet the needs of efficient collection of coal gangue dust, but also effectively resists dust wear, extending the service life of the exhaust fan 42. At the same time, the exhaust fan 42 is equipped with advanced noise reduction devices, such as soundproof covers and silencers, which can significantly reduce noise during operation, improve the working environment, and reduce noise pollution to the surrounding area.
[0030] As a further improvement of this utility model, a filter mechanism 5 is provided on the top of the brick making machine 2. The filter mechanism 5 includes a through pipe 51, and a dust collection box 52 is fixedly connected to the outside of the through pipe 51. A moving groove 53 is opened in the upper top wall of the dust collection box 52. A filter plate 54 is installed inside the moving groove 53. A sealing plate 55 is fixedly connected to the top of the filter plate 54. Positioning holes 56 are opened in the inner walls on both sides of the sealing plate 55. A connecting plate 57 is fixedly connected to the outside of the dust collection box 52. A movable pipe 58 is fixedly connected to the outside of the connecting plate 57. A snap-fit rod 59 is movably connected inside the movable pipe 58. A compression spring 510 is fixedly connected to the snap-fit rod 59. An air outlet pipe 511 is fixedly connected to the outside of the dust collection box 52.
[0031] It should be noted that: the dust collection box 52 is fixedly connected to the top of the brick making machine 2, the filter plate 54 is installed inside the dust collection box 52, the through pipe 51 and the air outlet pipe 511 are respectively located in the inner wall of the dust collection box 52 on both sides of the filter plate 54, the connecting plate 57 is symmetrically distributed on the outside of the dust collection box 52, and the initial position of the snap-fit rod 59 is inside the positioning hole 56.
[0032] Furthermore, the sealing structure of the dust collection box 52 has been comprehensively optimized. At the connection of the box body, multiple layers of rubber sealing gaskets and sealant are used for double sealing to ensure that dust-laden gas will not leak during the filtration process. At the same time, the cover of the dust collection box 52 adopts a special snap-on sealing design with the box body, which not only makes it easy to open and close, but also effectively prevents dust from entering and ensures that the filtration effect is not affected.
[0033] Furthermore, the dimensional accuracy of the locking rod 59 and the positioning hole 56 is controlled within a very small range to achieve a precise fit. The surface of the locking rod 59 is hardened to improve its wear resistance and fatigue resistance. The compression spring 510 is made of high-elasticity, high-strength alloy spring wire to ensure that the spring performance is stable during frequent pressing and resetting, and can always provide sufficient elasticity to ensure the stability of the filter plate 54 installation and the convenience of maintenance.
[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0035] Working Principle: The power supply box 41 provides power to the entire dust collection mechanism 4. When the coal gangue hollow brick manufacturing process starts, the exhaust fan 42 is turned on. The exhaust fan 42 starts to run, and its internal drive impeller rotates at high speed, creating a negative pressure environment inside the exhaust fan 42. Since the exhaust fan 42 is connected to the air inlet pipe 43, and the bottom of the air inlet pipe 43 is fixed with a suction plate 44, and the air inlet pipe 43 and the suction plate 44 are located above the inside of the brick making machine 2, with the length of the suction plate 44 being the same as the width of the inside of the brick making machine 2, the dust generated inside the brick making machine 2 is sucked into the air inlet pipe 43 from the suction plate 44 under the action of negative pressure. The large area design of the suction plate 44 allows it to cover a large area inside the brick making machine 2, effectively collecting dust generated at various locations. Subsequently, the dust enters the exhaust fan 42 through the air inlet pipe 43 with the airflow. The motor 45 on the outside of the brick making machine 2 starts, and the output end of the motor 45 drives the lead screw 46 to rotate inside the brick making machine 2. The collar 47, which is threaded to the outside of the lead screw 46, moves left and right along the axial direction of the lead screw 46 due to the rotation of the lead screw 46. The connecting rod 48, which is fixedly connected to the bottom of the collar 47, is connected to the top of the suction plate 44. Therefore, the movement of the collar 47 drives the suction plate 44 to move up and down synchronously. The operator can control the forward and reverse rotation and speed of the motor 45 through the controller 3. According to the changes in the amount of dust generated at different positions in the brick making machine 2, the position of the suction plate 44 can be flexibly adjusted. At the same time, the sliding rods 49, which are symmetrically distributed on the outside of the suction plate 44, slide at the end away from the suction plate 44 in the groove 410 opened in the inner wall of the brick making machine 2. The sliding rods 49 and the groove 410 cooperate to provide stable support for the movement of the suction plate 44, ensuring that the suction plate 44 remains stable during the left and right movement and does not shake, thus ensuring that the dust collection work continues to be stable.
[0036] The dust-laden gas collected by the dust collection mechanism 4 is drawn into the dust collection box 52 through the pipe 51 by the exhaust fan 42. The dust collection box 52 is fixed on the top of the brick making machine 2. The pipe 51 is connected to one side of the dust collection box 52 so that the dust-laden gas can smoothly enter the interior of the dust collection box 52. A filter plate 54 is installed inside the dust collection box 52. The filter plate 54 is installed in the moving groove 53. After the dust-laden gas enters the dust collection box 52, it flows from one side of the filter plate 54 to the other. During this process, dust particles are intercepted by the filter plate 54, while clean gas passes through the filter plate 54 and flows to the outlet pipe 511 on the other side of the dust collection box 52, opposite the filter plate 54. The material and structural design of the filter plate 54 enable it to effectively filter dust particles according to their size, ensuring that the discharged gas meets environmental protection standards. When the filter plate 54 needs to be cleaned or replaced, the snap-fit rod 59, which is movably connected inside the movable pipe 58 on the connecting plate 57 on the outside of the dust collection box 52, comes into play. The snap-fit rod 59 is initially positioned on the inner walls of the top sealing plate 55 of the filter plate 54. The compression spring 510 fixed on the locking rod 59 is in its natural state within the positioning hole 56, keeping the locking rod 59 within the positioning hole 56 and thus fixing the filter plate 54. During maintenance, the locking rod 59 is pulled to overcome the elasticity of the compression spring 510 and disengage from the positioning hole 56. At this time, the filter plate 54 can be removed from the moving slot 53 for cleaning or replacement. After maintenance, the filter plate 54 is reinstalled back into the moving slot 53, the locking rod 59 is released, the compression spring 510 returns to its original deformation, and the locking rod 59 is pushed back into the positioning hole 56, achieving a stable installation of the filter plate 54 and conveniently and quickly completing the maintenance work of the filter plate 54.
