Description
Technical Field
[0001] The present invention relates to the technical field of air control and pollution treatment, and particularly to an integrated automatic ash-discharging pulse bag filter. Background Art
[0002] The pulse bag filter is a commonly used high-efficiency dust removal device in the industrial field. Its core working principle is based on the interception and separation of dust by filter bags. The dusty gas enters the interior of the device through the air inlet. The dust is adsorbed on the outer surface of the filter bag, and the clean gas passes through the filter bag and is discharged from the air outlet. When the dust accumulation on the filter bag surface increases and the resistance rises, the pulse jet system is activated. Compressed air is sprayed into the filter bag through the pulse valve in a very short time and at high speed, causing the filter bag to expand and vibrate instantly, shaking off the attached dust, which falls into the ash hopper and is then discharged.
[0003] In the currently used dust collectors, the flow direction of air is fixed, and only one side of the filtering structure works. Therefore, there will be interception dead corners, and some interception structures do not work for a long time, resulting in uneven interception, which will affect the interception effect, and there is a lack of a cyclic working function for switching the interception cross-section.

An air extraction pump 15 is connected and arranged below one group of flow control gate valves 14, and the air extraction pump 15 is communicated with an output pipeline arranged below the other flow control gate valve 14; the top of the upper isolation transmission frame 4 is lower than the air outlet 103.
[0029] As Figures 1 - 9 shown, during use, the air inlet 102 is connected to the gas source to be processed, and dusty air is input; when the air enters the interior of the collector bin 1, it flows upward through the conical filter screen 305, and the light and larger-sized dust will be intercepted by the conical filter screen 305 and left on the outer surface of the conical filter screen 305 or directly fall into the ash discharge channel 2; The separation motor 301 is started to drive the bearing shaft 3 to rotate, and the bearing shaft 3 drives the disc 302, the inclined bracket 303, the fixed swivel 304, the conical filter 305 and the protective sleeve 306 to rotate synchronously. The rotation of the conical filter 305 can generate centrifugal force to throw off the dust intercepted outside the conical filter 305, so as to prevent the dust from clogging the conical filter 305 and affecting the interception effect. The protective sleeve 306 can rotate to throw off the dust attached to itself; after being thrown off, the dust falls into the ash outlet channel 2; the air moves upward and penetrates the long tube filter bag 503 to intercept the dust, and the intercepted air is discharged through the air outlet port 103; The reversing motor 8 is started to drive the linkage shaft 7 to rotate, and the linkage shaft 7 cooperates with the bevel gear to drive each group of driving worm 6 to rotate synchronously, and the driving worm 6 drives each group of driven worm gears 501 to rotate synchronously, so that the venturi tube 5 and the long-tube filter bag 503 can rotate synchronously and slowly, realizing automatic switching of the interception surface, avoiding the influence of flow direction causing dust to adhere to only part of the long-tube filter bag 503, and increasing the interception time; The long tube filter bag 503 can rotate automatically by setting a timing control switch, or can be kept rotating by continuously rotating at a slow speed; When pulse dust removal is required, stop inputting air into the collector bin 1, then open a group of branch solenoid valves 10 and the main solenoid valve 11, and perform dust removal on a group of branches of the injection integrated pipe 9 each time to ensure gas pressure. After releasing the compressed air in the energy storage device 12, the compressed gas passes through the inside of the injection integrated pipe 9 and is discharged into the venturi 5, generating pulses to shake off the dust outside the long-tube filter bag 503, and the dust falls into the ash outlet channel 2; after each branch dust removal, store energy for the energy storage device 12 again, and repeat the above steps to repeat dust removal; the energy storage device 12 uses a compressed gas accumulator, which is a device that uses compressed gas to store energy. Its working principle is that when there is excess energy, a compressor is used to compress air or other gases and store them in a high-pressure container, at which time electrical energy is converted into pressure energy of the gas; when energy is needed, the high-pressure gas is released to drive a turbine or other power equipment to convert pressure energy into mechanical energy or electrical energy, thereby achieving pulse release; The driving motor 203 is started to drive the screw propeller 202 to rotate, and the screw propeller 202 transports and squeezes the dust to the rectangular discharge port 204, so that the dust is compacted and difficult to disperse; A collecting container can be optionally provided outside the rectangular discharge port 204. When the dust extrusion pressure increases, the rotating sealing plate 205 will be opened to automatically discharge the dust outward. After the discharge is completed, the rotating sealing plate 205 will automatically close through the spring telescopic rod 206 to stop the discharge.
[0030] Embodiment 2: On the basis of Embodiment 1, instead of using a container to wrap the rectangular discharge port 204, it is possible to choose to connect a spray head 207 to a water pipe. During the process of squeezing the dust, water is input into the ash discharge channel 2 to mix the dust, making the dust heavier and unable to float easily. Then, in cooperation with the squeezing, the dust is turned into a solid and compact structure and discharged. A tray is arranged outside the rectangular discharge port 204 to recover the dust and clean the inside of the ash discharge channel 2.
[0031] Embodiment 3: On the basis of Embodiment 1, if there is a pressurized gas source, open the flow control valve 14 that is not connected to the air extraction pump 15 to directly discharge air to the outside; If it is necessary to actively inhale gas, it is necessary to close the flow control valve 14 at this place and open the flow control valve 14 connected to the air extraction pump 15. Use the air extraction pump 15 to actively extract air and exhaust through negative pressure to achieve a dual-selectable working effect.
[0032] Specific usage method and function of this embodiment: In the present invention, when in use, connect the air inlet pipe port 102 to the gas source to be processed and input dusty air; After the air enters the inside of the collector bin 1, it flows upward through the conical filter screen 305. Light and relatively large dust will be intercepted by the conical filter screen 305 and remain on the outer surface of the conical filter screen 305 or directly fall into the ash discharge channel 2; Start the separation motor 301 to drive the bearing shaft 3 to rotate. The bearing shaft 3 drives the disc 302, the inclined bracket 303, the fixed rotating ring 304, the conical filter screen 305 and the protective housing 306 to rotate synchronously. The rotation of the conical filter screen 305 can generate a centrifugal force to throw off the dust intercepted outside the conical filter screen 305, preventing the dust from blocking the conical filter screen 305 and affecting the interception effect. The rotation of the protective housing 306 can throw off the dust adhering to itself; after the dust is thrown off, it falls into the ash discharge channel 2; The air moves upward and penetrates into the long cylindrical filter bag 503 to intercept the dust, and the intercepted air passes through the air outlet pipe port 103 and is discharged; Start the reversing motor 8 to drive the linkage shaft 7 to rotate. The linkage shaft 7 cooperates with the bevel gears to drive each group of transmission worm gears 6 to rotate synchronously. The transmission worm gears 6 drive each group of driven worm wheels 501 to rotate synchronously, which can make the venturi tube 5 and the long cylindrical filter bag 503 rotate slowly synchronously, realizing automatic switching of the interception surface, avoiding only part of the outer surface of the long cylindrical filter bag 503 being attached with dust due to the influence of the flow direction, and increasing the interception time; the long cylindrical filter bag 503 can rotate automatically through timing control or can choose to rotate continuously at a slow speed to maintain rotation; After the long-tube filter bag 503 has worked for a certain period of time, the air input to the collector bin 1 is stopped, and then a group of branch solenoid valves 10 and the main solenoid valve 11 are opened to release the compressed air in the energy storage device 12. The compressed air passes through the inside of the spray integrated pipe 9 and is discharged into the venturi 5, generating pulses to shake off the dust outside the long-tube filter bag 503, and the dust falls into the ash outlet channel 2; each time a group of branches of the spray integrated pipe 9 is dusted, the gas pressure can be guaranteed, and after each branch is dusted, energy is stored in the energy storage device 12, and the above steps are repeated to repeat the dust removal; The driving motor 203 is started to drive the screw propeller 202 to rotate, and the screw propeller 202 transports and squeezes the dust to the rectangular discharge port 204 to compact the dust and make it difficult to disperse. A collecting container is set outside the rectangular discharge port 204. When the dust extrusion pressure increases, the rotating sealing plate 205 will be opened to automatically discharge the dust outward. After the discharge is completed, the rotating sealing plate 205 is automatically closed by the spring telescopic rod 206 to stop the discharge. The sprinkler head 207 can be connected to a water pipe to input water to mix the dust, so that the dust becomes heavy and cannot float easily, and then the dust is squeezed into a solid structure and then discharged. If there is a pressurized gas source, the flow control gate valve 14 not connected to the vacuum pump 15 can be opened to discharge air directly to the outside. Otherwise, the flow control gate valve 14 can be closed and the flow control gate valve 14 connected to the vacuum pump 15 can be opened. The vacuum pump 15 can be used to actively extract air and exhaust air through negative pressure to achieve a dual optional working effect.
