Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and more specifically, to a multi-stage integrated dust removal system. Background Technology

[0002] Abrasives are essential materials for manufacturing every precision product. Abrasives are prone to generating dust during processing. To prevent dust from being directly discharged outdoors, a bag-type pulse dust collector needs to be connected to the air outlet of the abrasive processing equipment.

[0003] For example, the DMC-200 bag pulse dust collector effectively removes dust generated during abrasive processing, preventing direct outdoor emissions that could impact the surrounding environment, thus demonstrating high environmental value.

[0004] However, this device has certain drawbacks: the dust collector filters air containing dust through filter bags. During use, dust in the air is easily adsorbed on the surface of the filter bags. If the dust collector runs for a long time, dust particles can easily clog the mesh of the filter bags, thus affecting the filtration effect of the filter bags and making the dust collector prone to malfunctions during operation. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-stage integrated dust removal system that avoids the filter bag being blocked by impurities during the use of the filter bag assembly and ensures the effectiveness of the filter bag assembly.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multi-stage integrated dust collection system includes a dust collection chamber with a top plate dividing the chamber into upper and lower sections. The bottom section is a dust-laden air layer, and the top section is a clean air layer. Multiple venturi tubes are installed on the top plate, with their lower sides extending through the lower surface of the top plate. Filter bag assemblies for filtering dust are installed below the venturi tubes. A striking component is installed on the outer side of the filter bag assembly. The striking component includes two mounting plates mirror-image positioned on the front and rear sides of the filter bag assembly. A movable cavity is formed on the lower side of each mounting plate, containing multiple striking rods. The other end of each striking rod slides through the outer surface of the mounting plate and can strike the filter bags of the filter bag assembly.

[0008] The present invention is further configured such that: a support is provided on the lower side of the dust removal box, a dust inlet pipe communicating with the interior is provided at the bottom of the front side of the dust removal box, a clean air outlet pipe communicating with the interior is provided at the top of the rear side of the dust removal box, a dust discharge pipe for discharging dust is provided at the bottom of the dust removal box, and a valve is provided on the dust discharge pipe.

[0009] The present invention is further configured such that: a pulse device is provided on the outside of the dust collector, and multiple pulse tubes are provided on the pulse device. One end of the pulse tube penetrates into the dust collector and is located in the clean air layer, and the jet nozzle at the bottom of the pulse tube faces the venturi tube.

[0010] The present invention is further configured such that: the upper sides of both mounting plates extend through the upper surface of the top plate; a rotating shaft is provided between the upper sides of the two mounting plates; a fan blade located on the upper side of the venturi tube is fitted on the outer surface of the rotating shaft; a transmission cavity is opened on the upper side of the mounting plate; the side of the rotating shaft near the mounting plate rotates and passes through the transmission cavity; a turntable is provided at one end of the rotating shaft located in the transmission cavity; a sleeve shaft is provided on the surface of the turntable facing away from the rotating shaft; the sleeve shaft is located at the eccentric position of the turntable; a rotating plate is rotatably fitted on the outer surface of the sleeve shaft; a control slide rod is hinged to the lower side of the rotating plate; the lower end of the control slide rod slides through the movable cavity.

[0011] The present invention is further configured such that: one end of the striking rod located in the movable cavity is provided with an inner plate, and a spring is provided between the inner plate and the inner wall of the movable cavity, which is movably sleeved on the outer surface of the striking rod.

[0012] The present invention is further configured such that: a movable plate is provided at the lower end of the control slide rod, a pressing protrusion is provided on the surface of the movable plate facing the striking rod, and a contact block that contacts the pressing protrusion is provided on the surface of the inner plate facing the movable plate.

[0013] The present invention is further configured such that one of the two adjacent extrusion protrusions contacts the adjacent contact block, while the other does not contact it.

[0014] The advantages of this utility model are:

[0015] This invention can automatically tap the surface of the filter bag during the operation of the dust removal system, causing the filter bag to shake. This causes the dust adhering to the surface of the filter bag to jump around under vibration, thereby preventing the filter bag assembly from being blocked by impurities during use, ensuring the effectiveness of the filter bag assembly, and improving the filtration effect of the dust removal system on gases containing impurities. At the same time, when the pulse equipment is running, the pulse airflow can also drive the fan blades to rotate, and at this time the tapping rod taps the filter bag, further improving the dust removal effect on the filter bag.

[0022] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1-4 The present invention provides the following technical solution:

[0025] Specifically, it refers to a multi-stage integrated dust removal system, including a dust collection box 1, a support 2 on the lower side of the dust collection box 1, a dust inlet pipe 3 communicating with the interior of the dust collection box 1 at the bottom front side, a clean air outlet pipe 5 communicating with the interior of the dust collection box 1 at the top rear side, a dust outlet pipe 4 for discharging dust at the bottom of the dust collection box 1, and a valve on the dust outlet pipe 4. A top plate 8 is provided inside the dust collection box 1, which divides the dust collection box 1 into upper and lower parts, with the bottom being a dust layer and the top being a clean air layer. Multiple venturi tubes 9 are provided on the top plate 8, with the lower side of the multiple venturi tubes 9 penetrating through the lower surface of the top plate 8. Filter bag assemblies 10 for filtering dust are provided below the venturi tubes 9.

[0026] In use, dust-containing gas is input into the dust layer inside the dust collector 1 through the dust gas inlet pipe 3. The gas rises and passes through the filter bag assembly 10. The dust in the gas is blocked by the filter bag assembly 10 and isolated on the outside of the filter bag assembly 10. The purified gas enters the clean gas layer through the venturi tube 9 and is finally discharged through the clean gas outlet pipe 5.

[0027] A pulse jet device 6 is installed on the outside of the dust collector 1. The pulse jet device 6 is equipped with multiple pulse tubes 7. One end of the pulse tube 7 penetrates into the dust collector 1 and is located in the clean air layer. The jet nozzle at the bottom of the pulse tube 7 faces the venturi tube 9. When it is necessary to clean the dust attached to the surface of the filter bag of the filter bag assembly 10, the valve of the dust discharge pipe 4 is opened first, the pulse jet device 6 is started, and the pulse tube 7 sprays out pulse airflow. The pulse airflow enters the filter bag assembly 10 through the venturi tube 9, causing the filter bag assembly 10 to shake, thereby shaking off the dust attached to the filter bag assembly 10. The shaken-off dust is finally discharged through the dust discharge pipe 4.

[0028] A striking component 11 is provided on the outer side of the filter bag assembly 10. The striking component 11 includes two mounting plates 111, which are mirror images of each other on the front and rear sides of the filter bag assembly 10. The upper sides of the two mounting plates 111 extend through the upper surface of the top plate 8. A rotating shaft 112 is provided between the upper sides of the two mounting plates 111. A fan blade 113 located on the upper side of the venturi tube 9 is sleeved on the outer surface of the rotating shaft 112. When the purified gas flows upward through the venturi tube 9, the airflow will drive the fan blade 113 to rotate, and the rotating shaft 112 will rotate synchronously.

[0029] A transmission cavity 114 is provided on the upper side of the mounting plate 111. The rotating shaft 112 is rotatably inserted into the transmission cavity 114 on the side near the mounting plate 111. A turntable 115 is provided at one end of the rotating shaft 112 located in the transmission cavity 114. A sleeve shaft 116 is provided on the surface of the turntable 115 facing away from the rotating shaft 112. The sleeve shaft 116 is located at the eccentric position of the turntable 115. A rotating plate 117 is rotatably sleeved on the outer surface of the sleeve shaft 116. A control slide rod 118 is hinged to the lower side of the rotating plate 117. A movable cavity 119 is provided on the lower side of the mounting plate 111. The lower end of the control slide rod 118 slides into the movable cavity 119.

[0030] In use, the rotating shaft 112 drives the turntable 115 to rotate, and the sleeve shaft 116 rotates synchronously with the turntable 115. At this time, the sleeve shaft 116 drives the rotating plate 117 to perform eccentric movement, and the rotating plate 117 can drive the control slide rod 118 to move up or down.

[0031] Multiple striking rods 1112 are provided inside the movable cavity 119. The other end of the striking rod 1112 slides through the outer surface of the mounting plate 111 and can contact the filter bag of the filter bag assembly 10. An inner plate 1113 is provided at one end of the striking rod 1112 inside the movable cavity 119. A spring 1114 is provided between the inner plate 1113 and the inner wall of the movable cavity 119 and is movably sleeved on the outer surface of the striking rod 1112. When the spring 1114 is not compressed, it will generate a pushing force on the inner plate 1113, so that the inner plate 1113 pulls the striking rod 1112 away from contacting the filter bag.

[0032] A movable plate 1110 is provided at the lower end of the control slide rod 118. A pressing protrusion 1115 is provided on the surface of the movable plate 1110 facing the striking rod 1112. A contact block 1116 is provided on the surface of the inner plate 1113 facing the movable plate 1110, which contacts the pressing protrusion 1115. When the control slide rod 118 moves the movable plate 1110 upwards or downwards, the pressing protrusion 1115 contacts the contact block 1116, and the pressing protrusion 1115 exerts a pushing force on the contact block 1116. The inner plate 1113 exerts a pushing force on the striking rod 1112. The force generated by step 12 causes the striking rod 1112 to strike the surface of the filter bag, resulting in a shaking effect. This causes the dust adhering to the surface of the filter bag to vibrate, thus preventing the filter bag assembly from being clogged by impurities during use. This further ensures the effectiveness of the filter bag assembly 10 and improves the filtration effect of the dust removal system on gases containing impurities. At the same time, when the pulse device 6 is running, the pulse airflow can also drive the fan blade 113 to rotate. At this time, the striking rod 1112 strikes the filter bag, further improving the dust removal effect on the filter bag.

[0033] In this embodiment, one of the two adjacent pressing protrusions 1115 contacts the nearby contact block 1116, while the other does not. Therefore, when the movable plate 1110 moves up or down, the two adjacent striking rods 1112 move in opposite directions, which improves the striking effect on the filter bag of the filter bag assembly 10.

[0034] The bottom of the movable cavity 119 is provided with a rubber buffer block 1111 that supports the movable plate 1110. By supporting the movable plate 1110 with the rubber buffer block 1111, the impact force when the movable plate 1110 falls can be reduced, thereby improving the service life of the movable plate 1110.

[0035] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
