Description

Technical Field

[0001] This utility model belongs to the field of ceramsite processing technology, and specifically relates to a dust suppression device for ceramsite processing. Background Technology

[0002] In modern ceramsite production processes, vibratory screening is an indispensable and crucial step, designed to classify the ceramsite by particle size to ensure that product quality meets standards. However, this process is accompanied by a serious problem: during vibratory screening, a large amount of dust mixed in with the ceramsite will be suspended in the air due to the continuous vibration of the ceramsite, forming a diffuse dust pollution environment. Long-term exposure to this high-concentration dust environment may cause operators to inhale a large amount of dust, leading to serious respiratory diseases such as pneumoconiosis, which will cause great damage to their health. This not only threatens the life and health safety of workers, but also brings potential occupational safety risks and legal liability hazards to ceramsite production enterprises.

[0003] To address this industry-wide challenge, researchers and manufacturers are constantly exploring effective dust suppression solutions. For example, Chinese patent application number CN201920769417.2 discloses a dust suppression device for ceramsite processing. This device innovatively uses water washing to flush away dust from the ceramsite, attempting to prevent dust from being suspended in the air during screening. Furthermore, it achieves water reuse through a filter plate, reflecting the concepts of environmental protection and resource conservation to a certain extent.

[0004] However, after practical application testing, this water-washing dust suppression method has revealed a series of obvious defects. When dust comes into contact with water, it easily adheres to the surface of the expanded clay aggregate. In the subsequent screening process, these dust-laden expanded clay aggregates will affect the accuracy and efficiency of the screening, leading to a decline in the appearance quality of the finished expanded clay aggregates. In fact, the residual impurities may even affect the performance of the expanded clay aggregates in practical applications, such as reducing the strength and durability of the products when used in building materials. In addition, the washed expanded clay aggregates require an additional drying process, which undoubtedly increases the complexity of the production process and energy consumption costs, and reduces production efficiency. It is evident that the existing technology has certain defects and shortcomings, and therefore needs to be improved. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a dust suppression device for ceramsite processing, so as to solve the problem that the existing method of using water washing for dust prevention is cumbersome and inconvenient.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A dust suppression device for ceramsite processing includes a mounting frame, a filter mechanism fixedly mounted on the back of the mounting frame, a suction fan fixedly mounted on the rear side of the filter mechanism, and an exhaust pipe fixedly mounted on the output end of the suction fan.

[0008] The filtration mechanism includes a suction hopper, which is fixedly installed on the back of the mounting frame. A collection component is fixedly installed at the bottom of the suction hopper. A square groove is opened in the middle of the suction hopper.

[0011] As a preferred technical solution, mounting plates are fixedly installed on both sides of the sealing plate, and a first screw is threadedly connected to the side of the mounting plate away from the sealing plate. The end of the first screw passes through the mounting plate and is threadedly connected to the collection box.

[0012] As a preferred technical solution, the first screw is configured as a hand-tightening screw, and the outer side of the sealing plate is provided with a groove.

[0013] As a preferred technical solution, the filter assembly includes a slide bar slidably connected to the inside of a slide groove. A filter screen is fixedly installed on the inner side of the slide bar. A cleaning brush assembly is fixedly installed in the middle of the side of the filter screen away from the suction fan. The cleaning brush assembly is in close contact with the outer surface of the filter screen. A sealing top plate is fixedly connected to the top of the filter screen. Positioning plates are fixedly installed on both sides of the sealing top plate. A second screw is threadedly connected to the lower end of the positioning plate.

[0024] Example

[0025] refer to Figures 1 to 5The dust suppression device for ceramsite processing in this embodiment includes a mounting frame 1, a filter mechanism 2 is fixedly mounted on the back of the mounting frame 1, a suction fan 3 is fixedly mounted on the rear side of the filter mechanism 2, and an exhaust pipe 4 is fixedly mounted on the output end of the suction fan 3.

[0026] The filtration mechanism 2 includes a suction hopper 21, which is fixedly installed on the back of the mounting frame 1. A collection component 22 is fixedly installed at the bottom of the suction hopper 21. A square groove 23 is opened in the middle of the suction hopper 21. Sliding grooves 24 are opened on both sides of the inside of the square groove 23. A filter component 25 is slidably connected inside the sliding grooves 24. The filter component 25 moves inside the square groove 23. During the use of this device, the mounting frame 1 can be fixed to the corresponding position of the ceramsite processing equipment. After the device is started, the suction fan 3 starts to run. Its powerful suction works through the suction hopper 21 to remove the dust-laden air generated during ceramsite processing. Under the influence of suction, the air quickly enters the suction hopper 21 and then enters the central square groove 23. At this time, the filter component 25, which is located in the square groove 23 and is slidably connected to the slide groove 24 on both sides, starts to work to filter and purify the dusty air. The filtered air is discharged from the exhaust pipe 4 through the suction fan 3. During the filtration process, the dust intercepted by the filter component 25 falls downwards due to gravity and is collected by the collection component 22 fixedly installed at the bottom of the suction hopper 21. When it is necessary to replace or clean the filter component 25, the filter component 25 can be easily pulled out along the slide groove 24 for easy maintenance.

[0027] refer to Figures 1-2 Mounting holes 5 are provided at each of the four corners of the mounting frame 1. The mounting holes 5 are countersunk holes. The countersunk holes at the four corners of the mounting frame 1 play an important role in the installation process. When bolts or other connectors are used to connect the mounting frame 1 to the ceramsite processing equipment or other related components, the special design of the countersunk holes allows the bolt heads to be recessed into the holes. This ensures that the surface of the mounting frame 1 remains flat after installation, avoiding the impact of protruding bolt heads on the overall aesthetics of the device and the fit with surrounding components. The flat mounting surface can effectively prevent protruding bolts from obstructing or interfering with the conveying and processing of ceramsite during the ceramsite processing process, ensuring the smooth progress of the ceramsite processing flow, improving the stability and reliability of the equipment operation, and enabling the mounting frame 1 to better perform its function of fixing and connecting various components of the device.

[0028] refer to Figure 1 and Figures 3-5The collection assembly 22 includes a guide hopper 221, which is fixedly connected to the bottom center of the suction hopper 21. The top of the guide hopper 221 is connected to the bottom of the suction hopper 21. A collection box 222 is fixedly installed at the bottom of the guide hopper 221. A collection drawer 223 is slidably connected inside the collection box 222. A sealing plate 224 is fixedly connected to the outer end of the collection drawer 223. Mounting plates 225 are fixedly installed on both sides of the sealing plate 224. A first screw 226 is threadedly connected to the side of the mounting plate 225 away from the sealing plate 224. The end of the first screw 226 passes through the mounting plate 225 and is threadedly connected to the collection box 222. The first screw 226 is a hand-tightening screw. A groove 227 is provided on the outer side of the sealing plate 224. When the collection assembly 22 is working, the dust that falls after being filtered from the suction hopper 21 enters the guide hopper 221 through the top of the guide hopper 221. The guide hopper 221 has a special... The inclined structure precisely guides the dust to the bottom, where it falls into the collection box 222 fixedly installed below. The collection drawer 223 inside the collection box 222 is used to store the dust. When the collection drawer 223 needs to be cleaned, the operator can hold the sealing plate 224 through the slot 227 on the outside of the sealing plate 224. Since the first screw 226 is a hand-tight screw, the operator can manually turn the first screw 226 to separate it from the collection box 222, and then pull out the sealing plate 224, causing the collection drawer 223 to slide outward from the inside of the collection box 222 along the track, completing the cleaning work. After cleaning, the operation is reversed, the collection drawer 223 is slid back into the collection box 222, and the first screw 226 is tightened again. The sealing plate 224 is then firmly fixed to the collection box 222 by the mounting plate 225, continuing to collect dust, thus achieving continuous collection and convenient cleaning of dust generated during the processing of ceramsite.

[0029] refer to Figures 3-4The filter assembly 25 includes a slide bar 251, which is slidably connected to the inside of the slide groove 24. A filter screen plate 252 is fixedly installed on the inner side of the slide bar 251. A cleaning brush assembly 253 is fixedly installed in the middle of the side of the filter screen plate 252 away from the suction fan 3. The cleaning brush assembly 253 and the outer surface of the filter screen plate 252 are in contact. A sealing top plate 254 is fixedly connected to the top of the filter screen plate 252. Positioning plates 255 are fixedly installed on both sides of the sealing top plate 254. A second screw 256 is threadedly connected to the lower end of the positioning plate 255, and the second screw 256 passes through the positioning plate 255. The cleaning brush assembly 253, connected to the suction hopper 21 by threads, includes a rail frame 2531 fixedly mounted on the front of the filter screen plate 252. A lead screw 2532 is rotatably connected inside the rail frame 2531. A drive motor 2533 is fixedly mounted on the top of the sealing top plate 254. The output end of the drive motor 2533 passes through the sealing top plate 254 and is fixedly connected to the top of the lead screw 2532. A slider 2534 is threadedly connected to the outer surface of the lead screw 2532. Brush plates 2535 are fixedly mounted on both sides of the slider 2534. One side of the brush plate 2535 is close to the filter screen plate 252. The filter assembly 25 of this device is connected to the filter screen 252 by a sliding strip 251 and a sliding groove 24. When the filter assembly 25 is working, the sliding strip 251 and the sliding groove 24 work together to securely install the filter screen 252 in the square groove 23. The drive motor 2533 is started, and its output shaft drives the lead screw 2532 to rotate within the rail frame 2531. Because the lead screw 2532 is threadedly connected to the slider 2534, the slider 2534 moves linearly along the lead screw 2532 within the rail frame 2531. The brush plates 2535 on both sides of the slider 2534 move with the slider 2534, always remaining in contact with the surface of the filter screen 252, thus filtering out dust generated during the processing of ceramsite. Air enters through the suction hopper 21 and is intercepted and filtered by the filter screen 252. The cleaning brush assembly 253, driven by the drive motor 2533, continuously brushes the surface of the filter screen 252 to prevent dust accumulation from affecting the filtration effect and ensure filtration efficiency. When it is necessary to disassemble and maintain the filter assembly 25, unscrew the second screw 256, and drive the sealing top plate 254 through the positioning plate 255, so that the slide bar 251 can be pulled out along the slide groove 24. The filter screen 252 and the cleaning brush assembly 253 can then be removed from the square groove 23 of the suction hopper 21. After maintenance, reverse the operation to install and reset, ensuring the continuous and stable operation of the device.

[0030] Operating Principle and Advantages: This device, through the coordinated operation of the suction fan 3 and the suction hopper 21, greatly improves the dust suppression efficiency and maintenance convenience during the ceramsite processing. During installation, the device is securely connected to the ceramsite processing equipment using the pre-drilled mounting holes 5 at the four corners of the mounting frame 1 and bolts. After installation, the suction fan 3 is activated, generating strong suction that draws in dust-laden air through the suction hopper 21. Once inside the suction hopper 21, the airflow is first efficiently filtered by the filter assembly 25. Simultaneously, the cleaning brush assembly 253 continuously brushes and cleans the surface of the filter assembly 25, preventing dust accumulation. Accumulation affects the filtration effect. The filtered air is discharged, while the intercepted dust is collected centrally by the collection component 22. This design abandons the traditional water washing dust prevention method and adopts full suction dust suppression, which avoids the problems of dust adhesion on the surface of ceramic particles and subsequent drying process caused by water washing from the root. When the filter component 25 needs to be cleaned and maintained, simply turn the second screw 256 to easily pull out the sealing top plate 254, drive the slide bar 251 out of the slide groove 24, and then completely remove the filter component 25 from the square groove 23. The whole process is simple to operate, which greatly improves the inspection and disassembly efficiency of the filter component 25 of the filter mechanism 2 and provides great convenience for subsequent maintenance work.

[0031] This device, by incorporating a collection component 22, effectively enhances dust collection efficiency and long-term operational stability. During operation, the drive motor 2533 is activated, outputting power to rotate the lead screw 2532. The rotation of the lead screw 2532 causes the slider 2534 to slide precisely linearly within the rail frame 2531, thereby displacing the brush plates 2535 on both sides of the slider 2534 vertically. During this vertical movement, the brush plates 2535 remain in close contact with the filter screen 252, effectively brushing away dust adhering to its surface. The dust falls under gravity to the guide hopper 221, where it is precisely guided and finally falls into the collection drawer 223 inside the collection box 222. This further improves dust collection efficiency. The dust collection effect is achieved by pre-adding an appropriate amount of clean water to the collection drawer 223. Utilizing the adsorption properties of water on dust, efficient dust collection and settling are realized. When it is necessary to clean the collection drawer 223, the second screw 256 is turned to move it outward, and then the sealing plate 224 is pulled out to easily remove the collection drawer 223 from the collection box 222, completing the cleaning work. This design not only enables the device to have a quick cleaning function, reducing maintenance time and labor costs, but also ensures the long-term efficient operation of the filter screen 252 through regular brushing and cleaning, maintaining its good dust collection performance. This greatly improves the practicality and reliability of the device in the ceramsite processing process and effectively guarantees the cleanliness and hygiene of the ceramsite production environment.
