Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically a box-type pulse dust collector. Background Technology

[0002] Due to their large filter area and high dust removal accuracy, cartridge dust collectors are widely used in dust-laden gas purification scenarios in industries such as machining, building materials production, and metallurgy, and are one of the core equipment for industrial dust control. However, most existing cartridge dust collectors adopt a single-sided air inlet design, which easily leads to a "local concentration" phenomenon after the dust-laden airflow enters the dust collection box. The front cartridge directly bears the impact of the high-speed airflow, resulting in excessive dust adhesion and concentrated load, which can easily lead to blockage and shorten service life. The rear cartridge, due to airflow attenuation, has insufficient dust adhesion, and its utilization rate can only reach 50%-60%. The overall filtration efficiency is severely restricted, and the front cartridge needs to be replaced frequently, increasing operation and maintenance costs.

[0003] Therefore, it is necessary to propose a box-type pulse dust collector to solve the above problems. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1: This Example 1 provides a box-type pulse dust collector, which is a direct improvement on an existing dust collector. It has a unique structure. Please refer to [link / reference]. Figure 1-8 As shown, it includes a dust collection box 1, and a fan 3 is fixedly installed on the top of the dust collection box 1. The output end of the fan 3 is connected to the interior of the dust collection box 1, and the air circulation inside the dust collection box 1 is achieved by the negative pressure provided by the fan 3.

[0018] Multiple cloth cylinders 8 are fixedly installed in an array inside the dust collector 1. The cloth cylinders 8 are fixedly installed inside the dust collector 1 by a tube sheet. The tube sheet is an existing structure and will not be described in detail. The cloth cylinders 8 are made of high-temperature resistant filter cloth material, which has good filtration performance and mechanical strength. The multiple cloth cylinders 8 are arranged in two rows, front and back. Compressed air tanks 9 are fixedly installed on both sides of the dust collector 1. The compressed air tanks 9 store high-pressure compressed air for cleaning the cloth cylinders 8.

[0019] Both compressed air tanks 9 are fixedly equipped with pulse solenoid valves 10. The output end of the pulse solenoid valve 10 is fixedly equipped with a nozzle 11. The other end of the nozzle 11 is sealed and extends into the dust collection box 1. The bottom of the nozzle 11 is fixedly equipped with nozzles that correspond one-to-one with the cloth cylinder 8. Through the periodic action of the pulse solenoid valve 10, the high-pressure airflow can be released instantaneously, thereby efficiently cleaning the cloth cylinder 8.

[0020] Multiple air inlets are vertically spaced along the front side of the lower chamber. Each row of cloth cylinders 8 has a corrugated guide plate 22 at the rear. The corrugated guide plate 22 has a corrugated structure design, which can guide the airflow to be evenly distributed. A baffle plate 20 is fixedly installed inside the air inlet. Multiple through holes are spaced along the length of the baffle plate 20. A funnel-shaped air collecting hood 21 is fixedly installed inside the through holes. The other end of the air collecting hood 21 extends into the dust collector box 1 and is close to the corrugated guide plate 22 at the front.

[0021] The front corrugated guide plate 22 has ventilation openings 23 corresponding to the cloth cylinders 8, and each ventilation opening 23 is located within the enclosed area of ​​the corresponding air collection hood 21 outlet. This structural design ensures that the dust-laden airflow is evenly distributed around each cloth cylinder 8. The bottom of the dust collector 1 has a dust discharge port for discharging the cleaned dust. A controller 24 is fixedly installed on one side of the dust collector 1. The fan 3 and the pulse solenoid valve 10 are both connected to the controller 24 for automated control.

[0022] The two rows of cloth cylinders 8 are arranged in front and behind, and each row is divided into left and right groups. Each group of cloth cylinders 8 is equipped with a nozzle 11 above it. Each compressed air tank 9 is fixedly installed with two pulse solenoid valves 10. The exposed end of the four nozzles 11 is connected to the corresponding pulse solenoid valve 10. This group control method can achieve selective dust removal, improve dust removal efficiency and reduce energy consumption.

[0023] A baffle 2 is installed inside the air inlet. The upper end of the baffle 2 is hinged to the dust collection box 1. A latch-type lock 28 is fixedly installed on the baffle 2. Hooks 4 are fixedly installed on both sides of the dust collection box 1 above and below the latch-type lock 28. The air inlet can be opened and closed by cooperating with the latch-type lock 28 and the hooks 4 in different positions. Multiple observation windows 7 are provided at intervals along the length of the front side of the dust collection box 1 to facilitate the operator to observe the working status of the cloth tube 8.

[0024] The dust discharge port is located at the bottom of the front side of the dust collector 1. A sealing plate 5 is installed inside the dust discharge port. The upper part of the sealing plate 5 is hinged to the dust collector 1. An inclined plate 14 is fixedly installed inside the dust collector 1, and the bottom edge of the inclined plate 14 is connected to the lower edge of the dust discharge port to facilitate the collection and discharge of dust. Inspection ports are provided on both the left and right sides of the dust collector 1. Inspection doors 6 are detachably installed inside the inspection ports to facilitate the maintenance and repair of the equipment.

[0025] Working principle: In the initial state, the hook-and-loop fastener 28 is hung on the corresponding hook 4 below it. At this time, the baffle 2 closes the air inlet. When using the dust collector for dust removal, first release the locking state of the hook-and-loop fastener 28, and then hang the hook-and-loop fastener 28 on the corresponding hook 4 above it. At this time, the baffle 2 separates from the air inlet, and the air inlet is in the open state.

[0026] Then, the fan 3 is turned on, and a negative pressure is formed under the action of the fan 3. The dust enters the dust collection box 1 through the air collection hood 21. Part of the air entering the dust collection box 1 will hit the front corrugated guide plate 22 and move to both sides with the corrugated trajectory of the front corrugated guide plate 22; the other part of the air passes through the vent 23 and hits the rear corrugated guide plate 22, and moves to both sides with the corrugated trajectory of the rear corrugated guide plate 22. This dual guide structure makes the dust concentration outside each cloth cylinder 8 uniform, thereby avoiding the situation that the front cloth cylinder 8 has a large load and the rear cloth cylinder 8 has a low utilization rate, thus improving the overall filtration efficiency and the service life of the cloth cylinder 8.

[0027] When a large amount of dust is observed to have accumulated on the outside of the cloth cylinder 8 through the observation window 7, the operator can activate the pulse solenoid valve 10 through the controller 24. The pulse solenoid valve 10 opens, and high-pressure gas is injected into each cloth cylinder 8 through the nozzle 11 and the nozzle. The compressed gas expands instantly inside the cloth cylinder 8, generating strong vibrations, which shakes off the dust on the outside of the cloth cylinder 8. The shaken-off dust slides down the inclined plate 14 and flows out from the ash discharge port.

[0028] Example 2: As Figure 3 , 5 As shown in Figure 7, the difference between this embodiment and Embodiment 1 is that it also includes a drive mechanism for opening and closing the sealing plate 5. The drive mechanism can realize the convenient opening and closing of the sealing plate 5, improving the convenience and safety of the ash removal operation.

[0029] The drive mechanism includes a rotating shaft 12 rotatably mounted above the inclined plate 14. One end of the rotating shaft 12 extends out of the dust collection box 1 and is fixedly mounted with a crank 13. By rotating the crank 13, the rotating shaft 12 can be rotated. Multiple fixed rods 25 are fixedly mounted at intervals along the axial direction at the bottom of the rotating shaft 12. The lower end of the fixed rod 25 is hinged to a connecting rod 26, and the other end of the connecting rod 26 is hinged to the sealing plate 5. When the rotating shaft 12 rotates, the opening and closing action of the sealing plate 5 can be realized through the transmission action of the fixed rod 25 and the connecting rod 26.

[0030] The drive mechanism also includes a limiting component, which includes an external gear ring 19 fixedly fitted on the exposed end of the rotating shaft 12, a rocker arm 13 fixedly installed on the top of the external gear ring 19, a connecting plate 15 horizontally provided below the external gear ring 19, one end of the connecting plate 15 being rotatably connected to the dust collection box 1, and a tension spring 18 fixedly installed on the top of the other end, the upper end of the tension spring 18 being fixedly connected to the dust collection box 1, and a clamping plate 17 fixedly installed on the top of the connecting plate 15, the clamping plate 17 being offset from the axis of the rotating shaft 12, and the upper end of the clamping plate 17 being inserted into the tooth groove of the external gear ring 19.

[0031] A sleeve is fixedly installed at one end of the connecting plate 15. A rotating rod 16 is rotatably installed inside the sleeve. The rotating rod 16 is fixedly connected to the dust collection box 1. Each compressed air tank 9 is equipped with a pressure gauge 27 to facilitate monitoring the air pressure status inside the compressed air tank 9.

[0032] The working principle is as follows: In the initial state, the sealing plate 5 is in the closed state, thereby preventing dust from falling from the cloth cylinder 8 and escaping into the external environment. When a lot of dust accumulates at the bottom of the dust collection box 1, the crank 13 is turned, and through the transmission of the rotating shaft 12, the fixed rod 25 and the connecting rod 26, the sealing plate 5 is opened to clean the dust.

[0033] When the crank handle 13 rotates, the external gear ring 19 rotates accordingly. At this time, the external gear ring 19 pushes against the retaining plate 17, causing the connecting plate 15 to rotate downward along the rotating rod 16 until the retaining plate 17 disengages from the tooth groove of the external gear ring 19. At this time, the external gear ring 19 and the retaining plate 17 slide relative to each other. When the crank handle 13 rotates to a certain angle, the connecting plate 15 will rotate upward under the action of the tension spring 18, causing the retaining plate 17 to re-insert into the tooth groove of the external gear ring 19, thus limiting the external gear ring 19.

[0034] This limiting structure can effectively prevent the sealing plate 5 from suddenly closing due to external force or its own weight when the staff is cleaning dust, thus improving the safety of operation. At the same time, the opening and closing of the sealing plate 5 is achieved by the drive mechanism, which is more labor-saving and convenient than manual operation, and is especially suitable for large dust removal equipment.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
