Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, and in particular to an environmentally friendly dust removal equipment for industrial production. Background Technology

[0002] With the acceleration of industrialization, various manufacturing industries are not only driving economic growth, but also facing severe challenges from environmental pollution, especially air pollution. Among them, the large amount of dust generated during the production process is one of the main air pollutants, which not only harms the health of workers, but also seriously affects the ecological environment and exacerbates global climate problems. Therefore, the development of efficient, energy-saving and environmentally friendly dust removal equipment has become an indispensable part of modern industrial production.

[0003] Currently, when treating industrial waste gas, enterprises typically use baghouse dust collectors to remove dust from the waste gas. Baghouse dust collectors are currently the most widely used high-efficiency dust removal equipment. Their principle is to use fiber-woven filter bags to capture dust particles. As airflow passes through the filter bags, the tiny dust particles are trapped on the surface of the filter material, thus achieving the effect of dust removal from the waste gas. However, after a period of use, existing baghouse dust collectors accumulate a large amount of dust on the surface of the filter bags. Therefore, to prevent the dust on the filter bag surface from affecting the dust removal efficiency, the filter bags are usually removed periodically for cleaning. However, removing and installing filter bags on existing baghouse dust collectors not only requires shutting down the dust collector, which affects the dust removal efficiency, but also the operation of removing and installing filter bags is cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0004] In view of this, the present invention provides an industrial environmental protection dust removal device that can solve the shortcomings of existing bag dust collectors, which not only require the bag dust collector to be shut down when removing and installing filter bags, thus affecting the dust removal efficiency of the bag dust collector, but also require cumbersome, time-consuming and labor-intensive operations when removing and installing filter bags.

[0005] The technical implementation scheme of the present invention is as follows: An industrial environmental protection dust removal device includes a bag filter, which includes a housing, an inlet pipe, an outlet pipe, a dust removal device, partition I and partition II. The inlet pipe and the outlet pipe are both connected to the housing. The dust removal device is installed on the housing. Partition I and partition II are both installed inside the housing. The device also includes guide rails, a movable ring, a hollow tube, a support frame, a cross ring I, an air supply pipe, a sleeve, a movable tube, a sealing disc, a leak-proof mechanism, a fixing mechanism, a sealing mechanism, an air supply mechanism, a dust blowing mechanism, and a blocking mechanism. At least two sets of guide rails are provided inside the housing, with four guide rails in each set. A movable ring is slidably arranged between each set of guide rails. The hollow tube is installed on the movable ring, and the support frame is installed on the hollow tube. The support frame is used to hold the filter bags. The partition I is open, with cross rings I spaced apart, the number of cross rings I being the same as the number of movable rings. The air supply pipe is installed on the cross rings I and is slidably connected to the hollow tube. The partition II is equipped with sleeves spaced apart, the number of sleeves being the same as the number of movable rings. The movable tube is slidably mounted on the sleeves. The partition II is equipped with sealing discs spaced apart, the number of sealing discs being the same as the number of sleeves, and the sealing discs are connected to the movable tube. The leak-proof mechanism is used to block the exhaust gas inside the casing. The fixing mechanism is used to fix the filter bags on the support frame. The sealing mechanism is used to seal the through hole in the middle of the movable ring. The air supply mechanism is used to input air into the sleeve. The dust blowing mechanism is used to blow off the dust on the surface of the filter bag. The blocking mechanism is used to block the dust inside the movable tube.

[0006] To further explain, the leak-proof mechanism includes a bellows I, a magnetic ring, and a movable cover. The bellows I are spaced apart on the housing, the magnetic ring is connected to the end of the bellows I, and the movable cover is installed on the housing. The movable cover is used to block the exhaust gas inside the housing, and the magnetic ring holds the movable cover in place by magnetic force.

[0007] To further explain, the fixing mechanism includes an electric push rod, a clamping plate, and a bellows II. The electric push rod is spaced apart on the movable ring. The clamping plate is connected to the telescopic rod of the electric push rod and is used to fix the filter bag on the support frame. The two ends of the bellows II are connected to the movable ring and the clamping plate respectively, and the electric push rod is located inside the bellows II.

[0008] To further explain, the sealing mechanism includes a vacuum pump I, a connecting pipe, and an air bladder. The vacuum pump I is mounted on the movable ring, one end of the connecting pipe is connected to the vacuum pump I, the air bladder is mounted on the movable ring, a hollow tube passes through the middle of the air bladder, and the other end of the connecting pipe is connected to the air bladder.

[0009] To further explain, the gas transmission mechanism includes a vacuum pump II, a main pipe, and electrically controlled valves I. The vacuum pump II is installed on the housing, the main pipe is connected to the vacuum pump II, and all sleeves are connected to the main pipe. Electrically controlled valves I are installed on the main pipe at intervals, and the number of electrically controlled valves I is the same as the number of sleeves.

[0010] To further explain, the soot blowing mechanism includes branch pipes, electrically controlled valve II, bellows III, and air jet pipes. The main pipe is connected to at least two sets of branch pipes, with four branch pipes in each set. Electrically controlled valve II is installed on the branch pipes, bellows III is connected to the branch pipes, and air jet pipes are connected to bellows III. The air jet pipes are also connected to the sealing disc.

[0011] To further explain, the blocking mechanism includes a cross ring II, a spring, a cross ring III, and a baffle. A cross ring II is installed inside the movable tube. One end of the spring is connected to the cross ring II, and the other end of the spring is connected to the cross ring III. The baffle is connected to the cross ring III and blocks the cross ring II.

[0012] Further explanation: It also includes a prompting mechanism, which includes a wind speed sensor, indicator lights, and a control box. The wind speed sensor is installed on the cross ring I, and indicator lights are spaced apart on the housing. The number of indicator lights is the same as the number of wind speed sensors. The control box is installed on the housing.

[0013] The beneficial effects of this invention are as follows: 1. This invention, through the cooperation of a movable ring, hollow tube, support frame, and fixing mechanism, can fix the filter bag inside the machine casing, so that people can install and remove the filter bag. Then, the dust in the exhaust gas is filtered out through the filter bag, thus removing dust from the exhaust gas. Afterwards, through the cooperation of a leak-proof mechanism, sealing mechanism, gas conveying mechanism, and blocking mechanism, the corresponding severely clogged filter bag can be replaced without affecting the normal operation of other filter bags. This achieves the purpose of replacing filter bags without stopping the machine. It is not only simple to operate and saves time and effort, but also improves dust removal efficiency.

[0014] 2. By setting up a dust blowing mechanism, the present invention can intermittently blow off the dust adhering to the surface of the filter bag, so as to prevent excessive dust from adhering to the surface of the filter bag and avoid the dust affecting the filter bag's filtration function.

[0015] 3. The present invention can automatically measure the air speed passing through the cross ring I through the prompting mechanism, thereby detecting whether the filter bag is severely clogged, so as to prompt people to replace the corresponding filter bag. Attached Figure Description

The sleeve 8 is movable; eight sealing discs 10 are slidably arranged on the partition plate II 106 at intervals, the number of sealing discs 10 is the same as the number of sleeves 8, and the sealing discs 10 are connected to the movable pipe 9; the anti-leakage mechanism is used to block the exhaust gas in the housing 101 to prevent the exhaust gas entering the housing 101 from leaking out; the fixing mechanism is used to fix the filter bag on the support frame 5 so that the filter bag can filter out the dust in the exhaust gas; the sealing mechanism is used to seal the through hole in the middle of the movable ring 3 to prevent the exhaust gas from leaking out through the through hole in the middle of the movable ring 3; the air conveying mechanism is used to input air into the sleeve 8; the dust blowing mechanism is used to blow off the dust on the surface of the filter bag so that the dust discharge device 104 can collect the dust in the exhaust gas in the housing 101; the blocking mechanism is used to block inside the movable pipe 9 so that after the air is input into the sleeve 8, the air can squeeze the movable pipe 9 and the sealing discs 10 to move until the sealing discs 10 contact the cross ring I6, and then the sealing discs 10 seal the cross ring I6.

[0043] See Figures 2-4 As shown, the leak-proof mechanism includes a bellows I11, a magnetic ring 111, and a movable cover 12; eight bellows I11 are spaced apart on the front side of the housing 101; the magnetic ring 111 is connected to the front end of the bellows I11; eight movable covers 12 are spaced apart on the front side of the housing 101. The movable covers 12 are used to block the exhaust gas inside the housing 101, and the movable covers 12 are made of iron so that the magnetic ring 111 can hold the movable covers 12 by magnetic force.

[0044] See Figure 5As shown, the fixing mechanism includes an electric push rod 13, a clamping plate 14, and a bellows II 15; four electric push rods 13 are spaced apart inside the movable ring 3; the clamping plate 14 is connected to the telescopic rod of the electric push rod 13, and the clamping plate 14 is moved by the electric push rod 13 to contact the filter bag on the support frame 5, so that the clamping plate 14 can fix the filter bag on the support frame 5; the two ends of the bellows II 15 are respectively connected to the movable ring 3 and the clamping plate 14, and the electric push rod 13 is located inside the bellows II 15, so that the bellows II 15 can prevent dust from adhering to the telescopic rod of the electric push rod 13, and avoid dust affecting the telescopic rod of the electric push rod 13 to extend and retract.

[0045] See Figure 9 and Figure 10 As shown, the sealing mechanism includes a vacuum pump I16, a connecting pipe 17, and an airbag 18. Vacuum pumps I16 are installed at the bottom of the upper movable ring 3 and at the top of the lower movable ring 3. One end of the connecting pipe 17 is connected to the air outlet of the vacuum pump I16. The airbag 18 is mounted on the movable ring 3, and a hollow tube 4 passes through the middle of the airbag 18. The other end of the connecting pipe 17 is connected to the airbag 18, allowing the vacuum pump I16 to inflate the airbag 18 by vacuuming until it contacts the outer wall of the hollow tube 4, thereby sealing the through hole in the middle of the movable ring 3.

[0046] See Figures 11-13 As shown, the gas delivery mechanism includes a vacuum pump II 19, a main pipe 20, and electrically controlled valves I 21. The vacuum pump II 19 is installed on the rear side of the housing 101. The main pipe 20 is connected to the outlet of the vacuum pump II 19, and all sleeves 8 are connected to the main pipe 20 so that the vacuum pump II 19 can draw air into the sleeves 8 through the main pipe 20. Eight electrically controlled valves I 21 are installed at intervals on the main pipe 20. The number of electrically controlled valves I 21 is the same as the number of sleeves 8. The eight electrically controlled valves I 21 are used to control the air in the main pipe 20 to flow into the eight sleeves 8.

[0047] See Figures 14-16 As shown, the dust blowing mechanism includes branch pipes 22, electrically controlled valve II 23, bellows III 24, and jet pipe 25; the main pipe 20 is connected to eight sets of branch pipes 22, and each set of branch pipes 22 has four branches; the electrically controlled valve II 23 is installed on the branch pipes 22; the bellows III 24 is connected to the branch pipes 22; the jet pipe 25 is connected to the bellows III 24, and the jet pipe 25 is connected to the sealing disc 10, and the jet pipe 25 is used to spray air into the filter bag, thereby blowing off the dust on the surface of the filter bag.

[0048] See Figure 18 and Figure 19As shown, the blocking mechanism includes a cross ring II 26, a spring 27, a cross ring III 28, and a baffle 29; a cross ring II 26 is provided inside the movable tube 9; one end of the spring 27 is connected to the cross ring II 26; the other end of the spring 27 is connected to the cross ring III 28; the baffle 29 is connected to the cross ring III 28, and the baffle 29 blocks the cross ring II 26.

[0049] In use, remove the movable cover 12 to separate it from the magnetic ring 111. Then, pull the support frame 5 forward, which in turn moves the hollow tube 4 and the movable ring 3 forward. Next, drive the clamping plate 14 away from the hollow tube 4 via the electric push rod 13. Then, put the filter bag on the support frame 5. Then, drive the clamping plate 14 closer to the hollow tube 4 via the electric push rod 13 until the clamping plate 14 contacts the filter bag on the support frame 5, thereby clamping the filter bag on the support frame 5 and fixing it. Then, push the filter cloth backward, which moves the support frame 5, hollow tube 4, and movable ring 3 backward to reset them, so that the movable ring 3 contacts the partition plate I 105. Finally, put the movable cover 12 back in its original position. The movable cover 12 is brought into contact with the magnetic ring 111. Then, the exhaust gas can be introduced into the housing 101 through the air inlet pipe 102, so that the exhaust gas is between the front side of the partition I 105 and the inside of the housing 101. The exhaust gas is filtered through the filter bag on the support frame 5. During this process, the gas in the exhaust gas will pass through the filter bag and enter the inside of the filter bag, while the dust in the exhaust gas is blocked on the outside of the filter bag. Then, the gas inside the filter bag will enter between the partition I 105 and the partition II 106 through the through hole in the middle of the movable ring 3 and the cross ring I 6, and then be discharged from the exhaust pipe 103. The dust blocked on the outside of the filter bag will adhere to the outside of the filter bag or fall down into the ash discharge device 104 for collection and discharge. In this way, the exhaust gas can be continuously treated for dust removal.

[0050] During continuous dust removal of exhaust gas, the electrically controlled valve II 23 can be opened, and air can be drawn into the main pipe 20, branch pipe 22, corrugated pipe III 24, and jet pipe 25 by the air pump II 19. The jet pipe 25 periodically sprays air, which passes between the partition I 105 and partition II 106, and then enters the filter bag through the cross ring I 6 and the movable ring 3. This blows off the dust adhering to the surface of the filter bag, causing the dust to fall downward into the ash discharge device 104 for collection and discharge. This prevents excessive dust from adhering to the surface of the filter bag and avoids dust affecting the operation of the filter bag. After the jet pipe 25 finishes spraying, the electrically controlled valve II 23 is closed. This process is repeated periodically to intermittently blow off the dust adhering to the surface of the filter bag.

[0051] When a filter bag is severely clogged and needs replacement, first hold the corresponding movable cover 12, then open the corresponding electrically controlled valve I21. Then, use the air pump II19 to draw air into the main pipe 20, sleeve 8, and movable pipe 9. Because the movable pipe 9 is blocked by the baffle 29, the air in the sleeve 8 will gradually compress the movable pipe 9 and the sealing disc 10, causing them to move forward (the sealing disc 10 drives the jet pipe 25 forward, and the bellows III24 is stretched), until the sealing disc 10 contacts the cross ring I6. This seals the cross ring I6, preventing gas from the filter bag from entering between the partition I105 and partition II106. When the movable pipe 9 contacts the air supply pipe 7, the air supply pipe 7 will enter the movable pipe 9, forming a connection. When the cross ring III 28 inside pipe 9 contacts the air supply pipe 7, the air supply pipe 7 will squeeze the cross ring III 28 and the baffle 29 to move backward. The spring 27 is compressed, so that the baffle 29 no longer blocks the cross ring II 26, thereby allowing the air in the sleeve 8 to enter the air supply pipe 7 through the movable pipe 9, and then allow the air to enter the corresponding hollow pipe 4 through the air supply pipe 7, so that the air in the hollow pipe 4 gradually increases, thereby squeezing the hollow pipe 4 to move forward, and thus driving the movable ring 3, the support frame 5 and the filter bag on it to move forward. When the filter bag on the support frame 5 contacts the corresponding movable cover 12, the filter bag on the support frame 5 will squeeze the corresponding movable cover 12 and the magnetic ring 111 to move forward, and the bellows I 11 will stretch. When the movable ring 3 contacts the inner front wall of the housing 101, at this time the support frame All filter bags on support frame 5 are inside corrugated pipe I11. Then, gas is drawn into airbag 18 through connecting pipe 17 using air pump I16, causing airbag 18 to inflate until it contacts the outer surface of hollow tube 4, sealing the through hole in the middle of movable ring 3 to prevent exhaust gas from escaping from the housing 101 through the through hole in the middle of movable ring 3. Then, the corresponding movable cover 12 is removed, separating it from magnetic ring 111. Then, the clamping plate 14 is moved away from hollow tube 4 by electric push rod 13, causing clamping plate 14 to release the corresponding filter bag. Then, the corresponding filter bag is removed from support frame 5, and a new filter bag is put back on support frame 5. Then, the clamping plate 14 is moved closer to hollow tube 4 by electric push rod 13. The device moves laterally until the clamping plate 14 contacts the new filter bag on the support frame 5, thus clamping the new filter bag on the support frame 5 with the clamping plate 14. Then, the corresponding movable cover 12 is returned to its original position, so that the corresponding movable cover 12 contacts the magnetic ring 111. Then, the air in the hollow tube 4 is extracted through the air supply pipe 7, movable pipe 9, sleeve 8, and main pipe 20 using the air pump II 19, so that the air in the hollow tube 4 gradually decreases, thus creating a negative pressure in the hollow tube 4. This causes the external air pressure to squeeze the corresponding hollow tube 4 to move backward and reset, thereby driving the movable ring 3, support frame 5, and the new filter bag on it to move backward and reset, so that the movable ring 3 separates from the inner front wall of the housing 101 and contacts the partition plate I 105. Then, the corresponding movable cover 12 is pressed to move backward and reset.The magnetic ring 111 moves backward to reset, causing it to compress the bellows I 11 and contract. Once the air in the hollow tube 4 is completely evacuated, the air pump II 19 extracts air from the sleeve 8 through the main pipe 20, gradually reducing the air volume in the sleeve 8 and creating a negative pressure. This negative pressure then forces the movable tube 9 and the sealing disc 10 to move backward to reset (the sealing disc 10 drives the jet pipe 25 to move backward, and the bellows III 24 contracts), causing the sealing disc 10 to separate from the cross ring I 6. This releases the seal of the cross ring I 6. When the cross ring III 28 in the movable tube 9 separates from the air supply pipe 7, the spring 27 returns to its original state, causing the cross ring III 28 and the baffle 29 to move forward to reset. Plate 29 blocks the cross ring II 26 again, preventing air from entering the air supply pipe 7 through the movable pipe 9. When the movable pipe 9 separates from the air supply pipe 7, the air supply pipe 7 will leave the movable pipe 9, creating a disconnect. Then, the corresponding electrically controlled valve I 21 is closed, and the air pump I 16 is used to extract the air from the airbag 18 through the connecting pipe 17, causing the airbag 18 to contract until it separates from the outer surface of the hollow tube 4. This prevents the airbag 18 from sealing the through hole in the middle of the movable ring 3, allowing the new filter bag on the support frame 5 to perform normal filtration. In this way, the severely clogged filter bag can be replaced without affecting the normal operation of other filter bags, achieving the goal of replacing filter bags without stopping the machine.

[0052] See Figure 22 and Figure 23 As shown, it also includes a prompting mechanism, which includes a wind speed sensor 30, an indicator light 32, and a control box 33; eight wind speed sensors 30 are provided on the cross ring I6, and the wind speed sensors 30 are used to detect the speed of air flow; eight indicator lights 32 are arranged at intervals on the housing 101, and the number of indicator lights 32 is the same as the number of wind speed sensors 30; the control box 33 is installed on the housing 101, and the wind speed sensors 30 and indicator lights 32 are electrically connected to the control box 33.

[0053] By setting up a wind speed sensor 30, the air velocity passing through the cross ring I6 can be measured to detect whether the filter bag is severely clogged. If the wind speed sensor 30 detects that the air velocity passing through the cross ring I6 is greater than a preset value, it means that the filter bag is not severely clogged and does not need to be replaced. If the wind speed sensor 30 detects that the air velocity passing through the cross ring I6 is less than a preset value, it means that the filter bag is severely clogged and needs to be replaced. In this case, the wind speed sensor 30 will send a signal. When the control box 33 receives the signal, it will control the corresponding indicator light 32 to light up, thereby prompting people to replace the corresponding filter bag.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
