Description

Technical Field

[0001] The invention relates to the technical field of air suction and dust removal devices, in particular to a constant pressure type air suction and dust removal device for a fabric textile processing plant. Background Art

[0002] In the process of fabric textile processing, such as drawing, opening and cleaning, combing and other processes, a large amount of dust and fiber will be generated in the fabric textile processing plant. The dust removal device can effectively remove dust for these processes to ensure the smooth progress of the production process. A Chinese patent discloses a workshop dust removal device with application number: 202322817435.2. When the filter plate is blocked, the device can move the filter plate and the spare filter plate horizontally together, move the spare filter plate to the dust removal bin, move the filter plate out, and then remove the filter plate for cleaning;

[0003] However, the current suction dust removal devices often clean the filter only after a large amount of dust has accumulated and clogged it. There is a lag in the cleaning work, and the compatibility between the dust removal work and the cleaning work is poor. Not only does the filter bear too much impact pressure during the dust removal process, affecting the service life of the device, but it also reduces the stability of the dust removal negative pressure. At the same time, since only the negative pressure part of the dust removal airflow can be used, the energy utilization rate of the device is insufficient, resulting in poor energy-saving effects, and the dust removal stability, efficiency and effect cannot be guaranteed. Summary of the invention

[0021] Compared with the prior art, the invention has the following beneficial effects: the invention has a scientific and reasonable structure and is safe and convenient to use;

[0022] 1. A continuous dust removal mechanism is provided. Through the coordination of the sleeve, inner cylinder, filter cartridge, rotary box, round seat and partition, a stable wind conversion cavity can be constructed, which can provide a relatively independent backblowing cleaning space for dust removal work while ensuring the stability of the overall dust removal negative pressure. It can effectively take into account the convenience of backblowing cleaning work and the stability of dust removal work, making the connection between dust removal work and backblowing cleaning work more stable and efficient, greatly improving the compatibility and adaptability between the two works. In addition, the transmission conversion function of the arc plug, rod body, empty cylinder, turbine, gear disc, double ball seat and ball head connecting rod can realize multiple conversion and utilization of dust removal wind force. On the one hand, synchronous backblowing cleaning can be realized in the dust removal process, which can greatly reduce the adhesion and accumulation time of dust in the filter cartridge, effectively reduce the probability of blockage of the device, make the airflow more smooth and efficient, effectively reduce the negative pressure fluctuation in the dust removal process, fully guarantee the stability and sufficiency of the dust removal negative pressure, make the dust removal work more stable and efficient, and effectively improve the efficiency of dust separation, greatly improve the dust removal effect;

[0023] On the other hand, it can effectively reduce the load pressure of the filter cartridge during dust removal work, and effectively reduce the airflow pressure during dust removal and cleaning work, which not only makes the cleaning work more stable and efficient, but also effectively improves its durability. On the other hand, it can equivalently realize the dual utilization of dust removal airflow, and can effectively and reasonably transform the pressure at the air outlet. In addition, the limiting flow guiding function of the suction valve, blowing valve, elbow, air hole, outlet valve, pipe body, air pipe and drainage pipe can realize the double superposition of dust removal negative pressure and the recycling of dust removal pressure, realize power recovery and superimposed utilization, greatly improve the effective utilization rate of energy of the device, and effectively reduce the load pressure of the device. While making the dust removal negative pressure more stable and sufficient, it is equivalent to improving the energy saving of the device. Through the coordination of gears, tooth grooves, exhaust pipes and scrapers, the dust removal pressure can be further transformed and utilized, and it can be coordinated with backblowing work to realize double cleaning of dust. While improving the effectiveness of cleaning work, it can further reduce the adhesion and accumulation time of dust on the filter cartridge and improve the cleaning effect.

[0024] 2. A dust collection and grabbing mechanism is provided. Through the cooperation of the dust collecting box and the filter cloth, a dust collection and storage space can be constructed, and the dust can be centrally restrained and stored, which greatly improves the convenience and reliability of dust collection and cleaning. In addition, the base, the conduit, the sealing shell, the port, the check valve, the connecting pipe, the connecting seat and the negative pressure pipe have the function of limiting the flow conversion, which can realize the dual utilization of the dust removal negative pressure in the dust removal process. On the one hand, it can cooperate with the continuous dust removal mechanism to superimpose the driving force of the air pump, and can compensate for the dust removal negative pressure, further improve the compatibility of the dust removal work and the back-blowing cleaning work, make the dust removal work more flexible and efficient, improve the suction stability of the device, and make the dust removal work more powerful and efficient. On the other hand, it can make full use of the negative pressure to preliminarily capture and adsorb the dust, effectively prevent the dust from escaping, and greatly improve the effectiveness and reliability of the dust removal work.

[0025] By cooperating with a water tank, a downpipe, a horizontal cylinder, an air tank, a return pipe, an outlet valve, a circular ring, a plug body, a compression spring and a block, a water circulation structure can be constructed, and the water flow pressure and gravity can be used as driving force to provide driving force for dust reduction and humidification. Without the aid of external force, it can be coordinated with a drain pipe, a hollow ring, a mist nozzle and a branch pipe to form a circulating humidification structure. On the one hand, it can further improve the energy-saving effect of the device, fully reduce the energy consumption of dust removal, and make the device more economical and practical. On the other hand, it can be coordinated with the dust capture and adsorption work to achieve double restrictions on dust, which can further improve the effective capture rate of dust and improve the effectiveness of dust removal. By cooperating with the filter seat, the sealing card plate and the drain valve, the clean water can be conveniently recovered, and the clean water can be recycled and reused, fully improving the green environmental protection during the operation of the device.

[0026] To sum up, the suction dust removal device can realize multiple transformations and utilizations of the dust removal airflow, can simultaneously superimpose the use of suction negative pressure and exhaust positive pressure, realize the recycling of suction dust removal pressure, and can take into account dust removal work and cleaning work, greatly improve the synchronization and timeliness of cleaning, greatly improve the stability of suction dust removal pressure, and simultaneously reduce the load pressure of the device and the impact of the airflow on the device. While improving energy-saving effects and dust removal efficiency, the device can be made more durable, and can achieve double limit on dust, which can fully avoid secondary dust escape and improve the dust removal effectiveness of the device.

[0055] Working principle and use process of the present invention: When the air suction dust removal device is actually used, firstly, the device is stably installed on the ground of the working area, the air suction pipe 21 is connected to the external air suction pipe, the plug cylinder 61 is connected to the external air supply pipe, the sealing card plate 326 is pulled out, and the water filter sponge is filled into the filter seat 325, and then the sealing card plate 326 is reset, and the filter seat 325 is re-sealed, and then the drain valve 327 is connected to the external water receiving device, and a proper amount of clean water is injected into the water tank 303, and then it can be officially put into use;

[0056] Turn on the air pump 5, and the air pump 5 sends the air flow into the top cavity of the double-cavity seat 4 through the exhaust pipe 51. Then the air flow will enter the corresponding rotary box 204 through each air receiving pipe 216, causing the turbine 217 to rotate under the air flow pressure. Then the air flow will be discharged into the base 304 through the exhaust pipe 223, and under the guidance of the bottom cavity of the double-cavity seat 4, it will enter the water tank 303 through the conduit 305, giving the water tank 303 internal pressure compensation, improving the water circulation efficiency, and making the dust reduction work more stable. Finally, the air flow enters the plug cylinder 61 through the exhaust valve 6, and flows into the external air supply pipe for further use;

[0057] During the rotation of the turbine 217, the gear plate 218 is driven to rotate synchronously, forcing the double ball seat 219 to deflect synchronously with the gear plate 218. Driven by the ball head connecting rod 220, when the double ball seat 219 approaches the rod body 211, the corresponding rod body 211 is pushed up by the ball head connecting rod 220, and when the double ball seat 219 approaches the rod body 211, the corresponding rod body 211 is pulled down by the ball head connecting rod 220. Since the two rod bodies 211 are respectively located on both sides of the gear plate 218, that is, when the double ball seat 219 approaches one of the rod bodies 211, the double ball seat 219 will be away from the other rod body 211, and then during the rotation of the gear plate 218, the two rod bodies 211 will rise and fall back and forth, and always maintain a state of one rising and one falling.

[0058] During the rising process of the rod body 211, it will push the corresponding arc plug 207 to rise synchronously, so that the airflow in the space between the bottom of the round seat 205 and the top of the corresponding arc plug 207 inside the inner tube 202 is pressed into the air hole 213, and under the guidance of the air outlet valve 214, it enters the rotary box 204 through the pipe body 215, and drives the turbine 217 to rotate together with the wind power provided by the air pump 5, so as to circulate and transform the power inside the device, reduce the load of the air pump 5, and make the rotation of the turbine 217 more efficient and stable. The more efficient and stable rotation of the turbine 217 will enhance the balance stability of the arc plug 207, thereby forming a double gain and improving the stability of the device;

[0059] During the descent of the rod body 211, the rod body 211 will drag the corresponding arc plug 207 down synchronously. At this time, under the guidance of the air intake valve 208, due to the increase in the distance between the round seat 205 and the corresponding arc plug 207, the air inside the filter cartridge 203 and the space where the top of the round seat 205 is located on one side of the arc plug 207 will be sucked into the cavity inside the inner cylinder 202 and the bottom of the round seat 205 is located on the top of the arc plug 207 through the air intake valve 208, thereby forming a negative pressure at the filter cartridge 203 on one side of the arc plug 207, and further forming a negative pressure in the space between the scraper 224 on this side and the filter cartridge 203, and under the conduction of the drainage pipe 225, the air inside the negative pressure box 2 is extracted, and under the conduction of the suction pipe 21, a negative pressure driving force is given to the external suction pipe to perform suction and dust removal operations;

[0060] Similarly, during the rising process of the arc plug 207, the space at its bottom becomes larger, and negative pressure is formed at the port 307, which continuously extracts the air inside the sealing shell 306, and under the guidance of the check valve 308, continuously extracts the air inside the connecting seat 310 through the connecting pipe 309, and forms a negative pressure at the negative pressure pipe 311, which cooperates with the air inlet pipe 52 to continuously extract the air inside the ash hopper 3 outside the dust box 301, and forms a negative pressure inside the dust box 301, so as to double-absorb the dust and prevent the dust inside the dust box 301 from escaping;

[0061] Similarly, during the descent of the arc plug 207, it will squeeze the air at its bottom, and under the guidance of the air blowing valve 209, the air is pressed into the space inside the filter cartridge 203 and the top of the round seat 205 on the other side of the partition 206 through the curved pipe 210, and the filter cartridge 203 on the other side is backblown. That is, during the entire working process, during the reciprocating lifting and lowering process of the arc plug 207, one side of the filter cartridge 203 on both sides of the partition 206 is positive pressure backblowing, and the other side is negative pressure adsorption, and they are reciprocated alternately, and negative pressure dust removal and backblowing operations are performed synchronously, so as to avoid dust accumulation on the outside of the filter cartridge 203, make the dust removal and backblowing operations more stable, and reduce the airflow pressure on the filter cartridge 203;

[0062] At the same time, due to the existence of the empty cylinder 212, the air pressed out from the bottom during the descent of the arc plug 207 will be smaller than the air extracted from the top, that is, the positive pressure value of the backblowing will be smaller than the negative pressure value of the suction, and the negative pressure state inside the negative pressure box 2 can be stably maintained, so that the external dust enters the external suction duct with the air flow under negative pressure adsorption, and passes through the suction duct 21 into the negative pressure box 2, and then enters the gap of the scraper 224 on this side through the drainage pipe 225 in the negative pressure state. Large particles of dust will fall along the gap of the scraper 224 under the action of their own gravity, and then pass through the gap between the double-chamber seat 4 and the base 304, and fall into the dust collecting box 301 along the ash hopper 3;

[0063] Small particles of dust are intercepted by the filter cartridge 203 and adsorbed on the filter cartridge 203. Then, when the filter cartridge 203 on this side enters the back-blowing state, they are dropped by the airflow. Under the action of their own gravity and the drive of the airflow, they fall along the gap of the scraper 224, and then pass through the gap between the double-chamber seat 4 and the base 304, and fall into the dust collecting box 301 along the ash hopper 3. At the same time, during this process, the rotation of the toothed disc 218 drives the inner cylinder 202 to rotate through the gear 221 and the tooth groove 222, forcing the filter cartridge 203 to rotate synchronously under the drive of the inner cylinder 202, so that the filter cartridge 203 and the scraper 224 are relatively displaced. During this process, the scraper 224 will continue to scrape the dust on the surface of the filter cartridge 203, and cooperate with the back-blowing operation to achieve synchronous double cleaning. In addition, the rotating movement of the filter cartridge 203 greatly reduces the adhesion and accumulation time of dust on the outside of the filter cartridge 203.

[0064] At the same time, the clean water inside the water tank 303 will flow into the horizontal cylinder 313 through the downpipe 312, and then pass through the gap between the ring 317 and the plug body 318, and be diverted on the other side of the ring 317. A small amount of clean water will flow into the drain pipe 321, and enter the hollow ring 322 through the branch pipe 324, and then be sprayed out from the atomizing nozzle 323 in an atomized state, so as to humidify the dust falling from the gap between the double-chamber seat 4 and the base 304, and cooperate with the negative pressure at the dust collecting box 301 to achieve double capture of dust and prevent dust from escaping.

[0065] It should be added here that: as the air inside the hopper 3 located outside the dust box 301 is continuously sucked into the negative pressure pipe 311 and the air inlet pipe 52, while a negative pressure is formed inside the dust box 301, the negative pressure will simultaneously act on the gap between the filter cartridge 203 and the scraper 224 inside the inner cylinder 202, and further act on the inner cavity of the negative pressure box 2 under the conduction of the drainage pipe 225, forming a complete negative pressure passage, that is, during the entire working process, only during the back-blowing operation, a local positive pressure will be formed on the outside of the filter cartridge 203 on the back-blowing side, thereby realizing multiple conversion and utilization of the airflow driving force of the air pump 5;

[0066] After the clean water passes through the gap between the ring 317 and the plug body 318, most of the clean water will enter the return pipe 315 under the guidance of the water outlet valve 316. In this process, under the impact of the clean water, the plug body 318 will move toward the side of the compression spring 319, so that the gap between the plug body 318 and the ring 317 becomes smaller, causing the water flow rate to increase, further expanding the pressure difference on both sides of the plug body 318, forcing the plug body 318 to move toward the side of the compression spring 319 more quickly, and finally the gap between the plug body 318 and the ring 317 will be blocked by the plug body 318.

[0067] At this time, the flowing water flow is suddenly cut off, which will cause the pressure inside the horizontal cylinder 313 to rise. Under the action of this pressure, the block 320 will overcome the top air pressure and rise along the gas tank 314. At this time, the pressure of the clean water inside the horizontal cylinder 313 will be amplified, and under this pressure, it will enter the space of the gas tank 314 located at the bottom of the block 320, and then flow into the return pipe 315. After the increased pressure is exhausted, the block 320 will reset under the top air pressure and press the clean water at its bottom into the return pipe 315. At the same time, the plug body 318 will also reset under the pressure of the compression spring 319. After returning to the initial state, the above process is repeated in a cycle.

[0068] The clean water entering the return pipe 315 will flow back into the water tank 303 under the increased pressure to form a complete water cycle. During the water circulation process, the atomizing nozzle 323 will intermittently spray water mist to the outside to humidify the dust. As the humidification work proceeds, some of the clean water adsorbed by the dust will penetrate into the filter seat 325, and after being filtered by the water filter sponge inside it, it will flow into the external water receiving device through the drain valve 327 to recover the clean water. The recovered clean water can be injected into the water tank 303 again for recycling.
