Description

Technical Field

[0001] The present invention relates to the field of woven bag dust removal, and in particular to an integrated woven bag crushing and dust removal device, system and control method. Background Art

[0002] Woven bags are widely used packaging materials in both industrial and civilian fields. Their main components are high molecular weight polymers such as polypropylene or polyethylene. Due to their stable chemical properties, these materials have a natural degradation cycle of decades or even centuries. If they are directly discarded or landfilled, they will cause serious pollution to the soil and water sources and occupy a large amount of land resources. Therefore, waste woven bags need to be recycled, and crushing is the core pretreatment step in the recycling process. Crushing facilitates subsequent cleaning, granulation and recycling.

[0003] On the one hand, the existing crushing equipment adopts the traditional crushing structure and principle, and the design of the crushing components is not reasonable. During the crushing process, the material is difficult to be fully crushed, resulting in low crushing efficiency, and often requires repeated crushing. It not only consumes a lot of time and energy, but also easily causes excessive wear of the crushing components, increases equipment maintenance costs, and at the same time, its crushing particle size is uneven, which cannot meet the requirements of some production processes that have strict requirements on material particle size, affecting the quality of subsequent products; on the other hand, most of the existing crushing equipment does not have a complete dust removal function. During the crushing process, a large amount of fine dust particles will be generated. These dusts fly around in the production workshop, which not only pollutes the working environment and seriously endangers the health of the operators. Long-term inhalation of dust can easily cause respiratory diseases and even pneumoconiosis; and the flying dust may also enter other equipment, affecting the normal operation of the equipment, causing equipment failure and reducing production efficiency; moreover, untreated dust discharged into the atmosphere will also pollute the surrounding environment, which does not meet environmental protection requirements.

[0032] A system for integrated woven bag crushing and dust removal equipment, comprising:

[0033] Control module, used to coordinate the operation of various components, receive signals, and execute logical control instructions;

[0034] The transmission module drives the transmission mechanism to transport woven bags and is used to control the transmission speed and start and stop;

[0035] Crushing module, used to control the start and stop and speed of the crushing mechanism to crush the woven bags;

[0038] Detection module, used to monitor the operating status of the equipment and trigger alarms or shutdowns;

[0039] The unloading module is used to control the start and stop of the unloading plate and the collecting mechanism to realize the collection and unloading of the crushed materials.

[0040] A method for using a woven bag crushing and dust removal integrated device, characterized by:

[0041] The control module sends a signal to the transmission motor to drive the drive shaft, which in turn drives the feed conveyor. Woven bags enter the dust box through the feed inlet and are transported by the feed conveyor to the discharge outlet above the crushing mechanism. An opening in the feed conveyor allows the first dust removal unit to absorb dust from the surface of the woven bags during transport. The first dust removal unit's exhaust fan operates synchronously, filtering dust from the air through the dust removal bags, which then falls into the ash hopper through the ash outlet. When the detection module detects elevated dust concentration, the control module activates the water inlet, causing the nozzle to spray water below the feed conveyor to suppress dust. Wastewater is discharged through the inclined plate and drain pipe.

[0042] The control module triggers the crushing motor to drive the output shaft and crushing drum of the crushing component to rotate; the woven bag falls from the transmission discharge port into the feed hopper of the crushing box and enters between the two crushing components; the spiral crushing knife cooperates with the crushing ports of the first crushing table and the second crushing table to cut the woven bag into pieces; the crushed material falls into the second dust removal box of the second dust removal unit through the crushing discharge port; the control module starts the material distribution motor to drive the material distribution shaft, and the guide plate and material distribution channel of the material distribution part distribute the crushed material evenly, and rotate with the material distribution shaft to between the air inlet nozzle and the blowing nozzle. The blower blows the material through the blowing nozzle, which not only has a dust removal effect, but also makes the crushed material quickly fall from between the extension plate and the second bent plate. The dust removal exhaust fan absorbs dust through the air inlet nozzle. When the first bent plate with a circular dust removal port faces the exhaust fan, the exhaust fan starts to absorb dust, and the crushed material is restricted by the first bent plate to continue to stay in the material distribution mechanism. The dust-laden air is filtered through the filter cartridge dust box, and the clean air is discharged through the exhaust pipe, and the dust is collected in the ash hopper;

[0043] The crushed material falls into the collecting mechanism through the discharge port of the discharge plate. When the material in the cart is too full and the discharge port cannot continue to discharge, the material accumulation sensor set at the discharge port will send an alarm signal to remind the operator to change the cart. There is no need for the operator to stay by the side to observe the loading of the cart.

[0044] The control module regularly triggers the external air source of the cleaning pipeline, and sprays compressed air into the dust removal bag through the air jet pipe to remove the attached dust; the operator can turn on the rotating motor through the control module to drive the baffle of the rotating shaft to rotate, open the ash outlet, and discharge the dust in the ash hopper.

[0045] The present invention has the following beneficial effects:

[0046] 1. The control module coordinates the operation of various components to achieve full automation of the entire process of woven bags from feeding to crushing, dust removal and discharging, reducing manual intervention and improving processing efficiency;

[0047] 2. During the conveying process of woven bags, the conveying mechanism absorbs surface dust through the first dust removal unit to achieve pre-dust removal and reduce dust diffusion in the subsequent crushing process; the crushing mechanism adopts a double crushing component spiral crushing blade structure, which cooperates with the crushing openings of the first and second crushing tables to quickly cut the woven bags into uniform fragments, with high crushing efficiency and convenient blade replacement (fixed by a positioning seat and a limit slot);

[0048] 3. The second dust removal unit realizes dynamic dust removal during the material transmission process through the rotation of the material distribution mechanism, the blowing nozzle and the exhaust fan, and the dust adsorption is more thorough. At the same time, the material distribution channel design can evenly distribute the material to avoid accumulation;

[0049] 4. Use dust removal bags to filter dust in the air, and use an air jet to clean dust regularly (compressed air injection) to ensure dust removal efficiency; a rotating baffle is set at the ash outlet to discharge dust regularly to prevent dust from being raised again;

[0050] 5. The circular dust removal port of the material distribution mechanism is used in conjunction with the exhaust fan. When the material rotates to the air inlet, the dust is adsorbed in a targeted manner; the dust-laden air is filtered through the filter cartridge dust removal box and then discharged, the clean air is discharged through the exhaust pipe, and the dust is collected in the ash hopper, effectively reducing dust overflow;

[0051] 6. When the dust concentration increases, the spray unit automatically sprays water through the nozzle to the bottom of the conveyor belt to suppress dust flying. The sewage is discharged through the inclined plate and the sewage pipe, further reducing the dust pollution in the workshop;

[0052] 7. The transmission mechanism of the present invention adopts a multi-stage driven shaft plus a curved transmission belt path, which effectively prolongs the residence time of the material in the dustproof box and ensures sufficient pre-dust removal; the opening design of the feed transmission belt can enhance the dust adsorption effect.

The woven bags enter the dust box 1 through the feed inlet 2 and are transported by the feed conveyor 26 to the discharge outlet 3 above the crushing mechanism 7. The opening 27 on the feed conveyor 26 allows the first dust removal unit 11 to absorb dust from the surface of the woven bags during transportation. The exhaust fan 53 of the first dust removal unit 11 operates synchronously, filtering dust from the air through the dust bag 37. The dust falls into the ash hopper 31 through the ash outlet 32. When the detection module detects an increase in dust concentration, the control module opens the water inlet pipe 58, and the nozzle 59 sprays water under the feed conveyor 26 to suppress dust from flying. Wastewater is discharged through the inclined plate 60 and the sewage pipe 61.

[0118] The control module triggers the crushing motor 67 to drive the output shaft 69 and the crushing cylinder 70 of the crushing component 63 to rotate; the woven bag falls from the transmission discharge port 3 into the feed hopper 68 of the crushing box 62 and enters between the two crushing components 63; the spiral crushing knife 76 cooperates with the crushing port 77 of the first crushing table 65 and the second crushing table 66 to cut the woven bag into pieces; the crushed material falls through the crushing discharge port 9 to the second dust removal box 12 of the second dust removal unit 10; the control module starts the distribution motor 82 to drive the distribution shaft 80, and the guide plate 89 and the distribution channel 90 of the distribution member 83 evenly distribute the crushed material. The material shaft 80 rotates to between the air inlet nozzle 16 and the blowing nozzle 92. The blower 91 blows the material through the blowing nozzle 92, which not only has a dust removal effect, but also makes the crushed material quickly fall from between the extension plate 85 and the second bent plate 88. The dust removal exhaust fan 15 absorbs dust through the air inlet nozzle 16. When the first bent plate 86 with a circular dust removal port 87 faces the exhaust fan 15, the exhaust fan 15 starts to absorb dust, and the crushed material is restricted by the first bent plate 86 and continues to remain in the distribution mechanism 13. The dust-laden air is filtered by the filter cartridge dust box 28, and the clean air is discharged through the exhaust pipe 53. The dust is collected in the ash hopper 31.

[0119] The crushed material falls into the material receiving mechanism 19 (cart or conveyor mechanism) through the discharge port 18 of the discharge plate 17. When the material in the cart is too full and the discharge port 18 cannot continue to discharge the material, the material accumulation sensor signal set at the discharge port 18 will send an alarm signal to remind the operator to change the cart. The operator does not need to stay by the side to observe the loading of the cart.

[0120] The control module periodically triggers the external air source of the dust cleaning pipe 39 to spray compressed air into the dust bag 37 through the air injection pipe 50 to remove the attached dust. The operator can use the control module to start the rotary motor, drive the baffle 56 of the rotating shaft 55 to rotate, open the ash outlet 32, and discharge the dust in the ash hopper 31.

[0121] A central processor coordinates multiple processes, including conveying, crushing, dust removal, and spraying, improving efficiency and reducing manual intervention. Sensors provide real-time feedback on equipment status, and integrated safety mechanisms prevent overload and dust explosion risks. Automatic mode enables on-demand component startup and shutdown, such as adjusting conveying speed based on material volume, to reduce energy consumption. Through precise logic control and component linkage, this operating system achieves automation, efficiency, and safety in the woven bag crushing and dust removal process.

[0122] In addition, the present invention also has the following advantages:

[0123] The detection module monitors dust concentration, motor load, material blockage and other conditions in real time, triggering alarms or shutdowns to avoid overload or dust explosion risks; a material accumulation sensor is installed at the discharge port, which automatically alarms when the cart is fully loaded, reminding you to replace the cart without manual supervision, improving safety and convenience; the control module can automatically adjust the transmission speed according to the material quantity, and start and stop components as needed (such as turning on the spray only when the dust concentration is high), reducing energy consumption. Each functional module (such as the crushing component, dust removal unit, and material distribution mechanism) has an independent structure and is easy to disassemble and maintain; the crushing knife is fixed by a limit slot and screws, and the entire equipment does not need to be disassembled for replacement, which reduces the difficulty and time cost of maintenance; the ash hopper and filter cartridge dust box collect dust in a centralized manner, which can be regularly and uniformly processed to reduce the frequency of manual cleaning; the rotating baffle and sewage pipe design facilitate the rapid discharge of dust and sewage, keeping the equipment clean; through efficient crushing and multi-stage dust removal, the present invention can significantly reduce dust pollution in the recycling process of waste woven bags, meeting environmental protection requirements; at the same time, the crushed material is convenient for subsequent cleaning, granulation and recycling, promoting the development of the plastic circular economy and reducing the harm of white pollution to the environment. The present invention realizes the automation, efficiency and safety of the woven bag crushing and dust removal process through the combination of mechanical structure innovation, intelligent control and environmental protection design.

[0124] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
