Description

Technical Field

[0001] The present invention relates to the technical field of purifiers, and in particular to a high-efficiency rotary wing purifier. Background Art

[0002] The waste gas generated during industrial production contains dust, which poses a serious threat to the environment and workers' health. Currently, the dust in the waste gas is mainly purified by rotary wing purifiers. After long-term use of the purifier, dust accumulates in the filter cartridge. Currently, a backflushing device is often set up to automatically clean the dust on the surface of the filter cartridge on a regular basis. However, during the backflushing process, it is often difficult to completely blow out the dust trapped in the gap of the filter cartridge, resulting in partial blockage of the filter cartridge, which affects the filtration efficiency of subsequent filter cartridges and causes a decrease in the cleaning effect of the purifier. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a high-efficiency rotary wing purifier, which solves the problem in the prior art that the accumulated dust trapped in the gaps between the filter cartridges is difficult to completely blow out, thereby affecting the filtration efficiency of subsequent filter cartridges.

[0004] To solve the above technical problems, the present invention provides the following technical solutions: a high-efficiency rotary wing purifier, comprising a plurality of processing chambers fixedly mounted on a frame, wherein a filter mechanism for quickly cleaning filtered dust and discharging the dust is provided on the inner side of the processing chamber, wherein the filter mechanism comprises a partition plate fixed on the inner side of the processing chamber, a plurality of array-distributed guide plates embedded in the partition plate, and a filter cartridge detachably arranged at the bottom of the guide plate, a sealing disc is provided on the top of the guide plate, and a blowing assembly for reverse blowing to remove dust accumulated in the filter cartridge is provided on the top of the partition plate, wherein a movable vertical pipe is fixed at the axis center of the sealing disc, a rotating wing frame rotatably connected to the guide disc is provided on the inner side of the filter cartridge, a threaded pipe is fixed at the bottom of the movable vertical pipe, and a threaded shaft threadedly connected to the threaded pipe is fixed on the top of the rotating wing frame, when the blowing assembly blows air, the sealing disc is pushed downward and the rotating wing frame is driven to rotate.

[0005] As a further optimization solution of the present invention, a return spring is sleeved on the outer side of the movable vertical pipe, and the upper and lower ends of the return spring are fixedly connected to the sealing disc and the guide disc respectively.

[0006] As a further optimization solution of the present invention, the blowing assembly includes a ventilation pipe fixedly arranged on the top of the inner side of the processing chamber, and the number of the ventilation pipes is set to be several and distributed at equal intervals.

[0007] As a further optimization solution of the present invention, the ventilation pipe is fixedly connected to a plurality of equally distributed air valves, the bottoms of the plurality of air valves are respectively fixedly connected to air injection pipes, and the number of air injection pipes and movable vertical pipes is set to be the same.

[0008] As a further optimization solution of the present invention, the top of the movable vertical pipe is sleeved on the outside of the bottom of the air jet pipe. When the air jet pipe is ventilated, the airflow pushes the movable vertical pipe to move downward, and the airflow enters the filter cartridge synchronously.

[0009] As a further optimization solution of the present invention, the bottom of the processing bin is fixedly connected to a dust collecting hopper, and a heavy hammer valve is fixedly installed at the bottom of the dust collecting hopper.

[0010] As a further optimization solution of the present invention, one side of the dust collecting hopper is fixedly connected to an air inlet pipe, and one end of the top of the processing bin is fixedly connected to an air outlet pipe.

[0011] As a further optimization solution of the present invention, a dust collector air bag is fixedly installed on the top of the frame, and one end of the ventilation pipe passes through the processing chamber and is fixedly connected to the dust collector air bag.

[0012] By means of the above technical solution, the present invention provides a high-efficiency rotary wing purifier, which has at least the following beneficial effects compared to the prior art: 1. The present invention provides a filtering mechanism to quickly blow out the dust accumulated in the filter cartridge. When purifying the exhaust gas, the exhaust gas enters from the bottom of the filter cartridge, and after the dust is filtered out by the filter cartridge, the exhaust gas enters the exhaust pipe through the guide plate and is discharged. When the blowing assembly blows air, it pushes the sealing disc downward and drives the rotating wing frame to rotate in the filter cartridge. When the air flow enters the filter cartridge, the rotating wing frame rotates in the filter cartridge, which can more thoroughly clean the dust accumulated in the filter cartridge, avoids the blockage of the filter cartridge due to inadequate local cleaning, ensures that the filter cartridge is fully cleaned, and greatly extends the service life of the filter cartridge, thereby reducing the frequency of replacing the filter cartridge and reducing maintenance costs.

[0013] 2. The present invention sets an air blowing component to blow air in the reverse direction to remove the dust accumulated in the filter cartridge. The dust collector air bag passes the airflow into the jet pipe through the vent pipe, and the airflow enters the filter cartridge. At the same time, the airflow pushes the movable vertical pipe to move downward, and the movable vertical pipe drives the rotating wing frame to rotate inside the filter cartridge to further clean the dust accumulated in the filter cartridge. The dust accumulated in the filter cartridge can be completely removed, ensuring a stable filtering effect and improving the practicality of the purifier.

[0014] 3. When the movable vertical pipe of the present invention moves downward, it drives the sealing disc to contact the guide disc, thereby sealing the top of the filter cartridge to prevent the blown dust from floating above the partition plate and affecting the cleaning effect. At the same time, the movable vertical pipe moves downward to compress the return spring. When the blowing is completed, the return spring recovers its elastic deformation and pushes the movable vertical pipe upward, so that the sealing disc returns to its original position, and the exhaust gas can continue to be processed, making the dust removal and purification effect more comprehensive, ensuring the long-term and stable operation of the purifier, and avoiding equipment shutdown due to filter cartridge blockage.

[0017] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] First embodiment With the advancement of industrialization, the waste gas generated in the industrial production process poses a serious threat to the environment and workers' health. At present, the waste gas is first purified by the purifier before being discharged. The backflush device set in the current purifier is difficult to completely blow out the dust mixed in the gap of the filter cartridge, resulting in a decrease in the filter efficiency of the filter cartridge. In order to more thoroughly clean the dust in the filter cartridge 43 and ensure that the filter cartridge 43 is fully cleaned, refer to Figure 1 - Figure 4 This embodiment provides a high-efficiency rotary wing purifier, which consists of a frame 1, a processing chamber 2 and a filtering mechanism 4. The number of processing chambers 2 is set to three, and the three processing chambers 2 are all fixedly mounted on the frame 1, and the inner sides of the three processing chambers 2 are in an independent state.

[0019] In order to make the dust accumulation in the cleaned filter cartridge 43 more thorough and avoid the clogging of the filter cartridge 43 due to inadequate local cleaning, a filter mechanism 4 for quickly cleaning and filtering out dust and discharging it is provided on the inner side of the processing chamber 2. Specifically, the filter mechanism 4 includes a partition plate 41 fixed to the inner side of the processing chamber 2, the partition plate 41 divides the processing chamber 2 into two layers, a plurality of array-distributed guide plates 42 embedded in the partition plate 41, and a filter cartridge 43 provided at the bottom of the guide plate 42. A filter element is provided on the inner side of the filter cartridge 43 to filter out dust in the exhaust gas. The filter cartridge 43 is located on the bottom side of the partition plate 41, and the guide plate 42 is fixedly connected to the filter cartridge 43 by bolts. When a filter cartridge 43 fails, the filter cartridge can be repaired or replaced without affecting other filter cartridges 43, reducing the complexity of maintenance. A sealing disc 44 is provided on the top of the guide plate 42. When the sealing disc 44 moves downward and contacts the guide plate 42, the top of the filter cartridge 43 is in a sealed state, thereby preventing the blown dust from floating above the partition plate 41 and affecting the cleaning effect, making the dust removal and purification effect more comprehensive.

[0020] Among them, a movable vertical pipe 441 is fixed at the axis of the sealing disc 44, and a return spring 442 is sleeved on the outer side of the movable vertical pipe 441. The upper and lower ends of the return spring 442 are fixedly connected to the sealing disc 44 and the guide disc 42 respectively. The movable vertical pipe 441 moves downward to squeeze the return spring 442 and is compressed. When the blowing is completed, the return spring 442 recovers its elastic deformation and pushes the movable vertical pipe 441 to move upward, so that the sealing disc 44 returns to its original position, and the exhaust gas treatment can continue, which improves the flexibility and practicality of the purifier. The inner side of the filter cartridge 43 is provided with a rotating wing frame 443 that is rotatably connected to the guide disc 42. A threaded tube 444 is fixed to the bottom of the vertical tube 441, and a threaded shaft 445 threadedly connected to the threaded tube 444 is fixed to the top of the rotating wing frame 443. When the blowing assembly 45 blows air, it pushes the sealing disc 44 to move downward and drives the rotating wing frame 443 to rotate. When the threaded tube 444 moves downward, the internal thread of the threaded tube 444 and the external thread of the threaded shaft 445 are correctly matched. The threads inside the threaded tube 444 will engage with the external threads of the threaded shaft 445, thereby generating friction, pushing the threaded shaft 445 to rotate, and then driving the rotating wing frame 443 to rotate, so as to more thoroughly clean the dust accumulated in the filter cartridge 43.

[0021] In order to prevent the purifier from back-suctioning during the back-flushing cleaning process and to prevent dust from being re-sucked into the filter cartridge 43, a dust collecting hopper 5 is fixedly connected to the bottom of the processing bin 2, and a weight valve 6 is fixedly installed at the bottom of the dust collecting hopper 5. In the process of cleaning the dust in the filter cartridge 43, the airflow direction of the purifier is unidirectional, which helps to improve the back-flushing efficiency and make the cleaning of the filter cartridge 43 more thorough; a dust collecting bag can be installed at the bottom of the weight valve 6. When the collected dust exceeds the set value, the valve disc of the weight valve 6 is lifted up and the dust falls into the dust collecting bag; after the pressure is restored, the valve disc of the weight valve 6 returns to its seat to continue to form a seal.

[0022] An air inlet pipe 7 is fixedly connected to one side of the dust collecting hopper 5, and the exhaust gas to be purified enters the dust collecting hopper 5 through the air inlet pipe 7, and then enters the filter cartridge 43 upward for filtering and cleaning of the dust. An exhaust pipe 8 is fixedly connected to the top end of the processing chamber 2, and the purified exhaust gas enters the top side of the partition plate 41 through the guide plate 42, and is then discharged through the exhaust pipe 8 to proceed to the next operation; when purifying the exhaust gas, the guide plate 42 is in an open state, and when cleaning the dust in the filter cartridge 43, the sealing disc 44 is covered on the top of the guide plate 42, so that the guide plate 42 is in a closed state, and then the dust cleaning work is carried out, which helps to improve the effect of purifying the exhaust gas and will not affect the subsequent thorough cleaning of the dust in the filter cartridge 43, ensuring that the purifier can work stably for a long time.

[0023] Second embodiment In order to completely remove the dust in the filter cartridge 43, ensure the stable filtering effect and extend the service life of the filter cartridge 43, refer to Figure 2 - Figure 3 The top of the movable vertical pipe 441 is sleeved on the outer side of the bottom of the jet pipe 453, and each jet pipe 453 is provided with an independent air valve 452. The cleaning process is carried out separately, and the cleaning timing can be accurately controlled as needed to avoid cross contamination between different filter cartridges 43. At the same time, the cleaning force and frequency can be more accurately controlled to avoid the loss of the filter cartridge caused by excessive cleaning, thereby extending the service life of the filter cartridge. When the jet pipe 453 is ventilated, the airflow pushes the movable vertical pipe 441 downward, and the airflow enters the filter cartridge 43 synchronously.

[0024] In order to ensure that the purifier can perform exhaust gas purification work in a long-term and stable manner and avoid equipment shutdown due to blockage of the filter cartridge 43, a dust collector air bag 3 is fixedly installed on the top of the frame 1, and one end of the ventilation pipe 451 passes through the processing bin 2 and is fixedly connected to the dust collector air bag 3. The dust collector air bag 3 can provide compressed air to clean the filter cartridge 43 by pulse backblowing. The airflow is passed into the jet pipe 453 through the ventilation pipe 451, and the airflow enters the filter cartridge 43. At the same time, the airflow pushes the movable vertical pipe 441 to move downward, and the movable vertical pipe 441 drives the rotating wing frame 443 to rotate inside the filter cartridge 43, thoroughly cleaning the accumulated dust in the filter cartridge 43, thereby improving the filtration efficiency and service life of the purifier.

[0025] When cleaning the dust accumulated in the filter cartridge 43, the present invention provides compressed air through the dust collector air bag 3, and the air flow enters the air jet pipe 453 through the vent pipe 451, and the air flow enters the filter cartridge 43. At the same time, the air flow pushes the movable vertical pipe 441 to move downward, and the movable vertical pipe 441 drives the rotating wing frame 443 to rotate inside the filter cartridge 43. The air flow blows off the dust in the filter cartridge 43, and at the same time cooperates with the rotating wing frame 443 to further clean the dust in the filter cartridge 43, and completely removes the dust in the filter cartridge 43, thereby avoiding the blockage of the filter cartridge 43 due to inadequate local cleaning.

[0026] During actual use of the purifier, the exhaust gas to be purified is introduced into the air inlet pipe 7, and the exhaust gas enters the dust collecting hopper 5 through the air inlet pipe 7, and then enters the filter cartridge 43 upwards. The dust contained in the exhaust gas is filtered out by the filter cartridge 43, and the purified exhaust gas enters the top side of the partition plate 41 through the guide plate 42, and is then discharged through the air outlet pipe 8 to proceed to the next operation. After the exhaust gas has been purified for a period of time, compressed air is provided through the dust collector air bag 3, and the air valve 452 is opened. The air flow passes through the vent pipe 451 and enters the air injection pipe 453, and the air flow enters the filter cartridge 43. The air flow blows the dust accumulated in the filter cartridge 43 into the dust collecting hopper 5; At the same time, the airflow pushes the movable vertical pipe 441 to move downward, and the movable vertical pipe 441 drives the threaded tube 444 at its bottom end to move downward, and the internal thread of the threaded tube 444 and the external thread of the threaded shaft 445 match each other, and the thread inside the threaded tube 444 will engage with the external thread of the threaded shaft 445, driving the threaded shaft 445 to rotate, and the threaded shaft 445 drives the rotating wing frame 443 at its bottom end to rotate, and the rotating wing frame 443 rotates inside the filter cartridge 43, further cleaning the dust in the filter cartridge 43 into the dust collecting hopper 5, and the dust is collected at the bottom of the dust collecting hopper 5 and discharged through the weight valve 6. When the dust collected at the bottom of the dust collecting hopper 5 exceeds the set value, the valve disc of the weight valve 6 is lifted up, and the dust falls directly into the dust collecting bag, and the cleaning of the filter cartridge 43 is completed.
