Further, referring to fig. 1, a dust collector according to an embodiment of the present invention is shown. The dust collector includes an air inlet switching valve 130, an air outlet switching valve 140, a plurality of dust chambers 200, and a shaking motor 232 and a filter 231 provided corresponding to each dust chamber 200. Specifically, for ease of illustration and understanding, two clean rooms 200 are provided in this embodiment of the utility model, one on the left and one on the right, respectively, as oriented in FIG. 1. Also, in order to facilitate understanding, in the embodiment shown in fig. 1, an air inlet pipe 110 for allowing the exhaust gas to enter and an air outlet pipe 120 for allowing the filtered gas to flow out are further provided.

It is understood that in other embodiments, there may be more than two dust chambers 200, and the shape and switching manner of the air intake switching valve 130 should be changed accordingly.

Each dust chamber 200 is provided therein with a filter device, the filter device includes a filter 231 and a shaking motor 232 connected to the filter 231, and the shaking motor 232 is used for shaking off dust adsorbed on the filter 231. At least a part of the dust can fall to the dust collecting part when the dust falls from the filter 231.

In one specific example, the filter 231 is a mesh filter 231, and a plurality of sets of filter pores with different pore sizes are disposed in the mesh filter 231. In the adjacent sets of filter holes, the filter holes near the air inlet 210 have a larger aperture than the filter holes near the air outlet 220. As shown in fig. 1, the mesh filter 231 in the present embodiment is provided with only two sets of filter pores, i.e., a large pore filter pore and a small pore filter pore.

After the dust gets into dust removal chamber 200 along with waste gas, at first contact the filtration pore of great aperture, the dust of great granule in the waste gas at first adsorbs to be blockked by the large aperture filtration pore, is adsorbed on the filter screen of large aperture filtration pore department, and less granule is blockked by the small aperture filtration pore afterwards, is adsorbed on the filter screen of small aperture filtration pore department.

Further, in one specific example, when assembled for use, the mesh filter 231 is vertically disposed in the dust chamber 200, the air inlet 210 is disposed below, and the air outlet 220 is disposed above. With this arrangement, when the vibration motor 232 vibrates the mesh filter 231 to remove the dust attached thereto, the small-particle dust attached thereto can normally pass through the large-aperture filter hole located below, and fall down to the dust collecting unit.

When the shaking motor 232 is turned on, the shaking shaft 233 starts shaking, and the mesh filter 231 is shaken as a whole, and dust attached thereto drops, thereby completing the self-cleaning of the mesh filter 231.

In practical operation, the air inlet switching valve 130 can be switched according to the working time length to switch the dust chamber 200 communicated with the air inlet pipe 110. One of the dust chambers 200 is now in communication with the air inlet duct 110 so that the dust remover can still function properly. And the air inlet 210 of the other dust chamber 200 is closed, the vibration motor 232 corresponding to the closed dust chamber 200 is turned on and shakes off the dust adsorbed on the filter 231, and the cleaning of the filter 231 in the closed dust chamber 200 is completed.

Further, by providing the mesh filter 231 having a specific pore structure, the filtering efficiency and the cleaning efficiency of the filter 231 in the dust removing chamber 200 can be improved, and the structural design of the interior of the dust remover can be simplified.

More specifically, the sensor 240 is disposed on the filter 231 near the outlet 220 for detecting the pressure or temperature of the filtered exhaust gas. When the detected air pressure or temperature is lower than the preset air pressure threshold or temperature threshold, the controller controls the air inlet conversion valve 130 to automatically switch the opened air inlet 210, so that the dust removal chamber 200 which is originally in the working state enters a cleaning state, the dust removal chamber 200 which is originally in the standby state enters the working state, and the dust remover body does not stop working.

In one specific example, the dust remover further comprises an air outlet switching valve 140, wherein the air outlet switching valve 140 is disposed at the air outlet 220 of each dust chamber 200, and is used for controlling the opening of the air outlet 220 of each dust chamber 200. Further, the outlet switch valve 140 is an outlet 220 cover plate, and one end of the outlet 220 cover plate is rotatably connected to the wall of the public chamber. Further, an air inlet switching valve 130 may be further provided to be linked with the air outlet switching valve 140, so as to close the clean room 200 in the working state and open the clean room 200 in the standby state, thereby stabilizing the air duct in the clean room 200.

In one specific example, the dust collecting part has a dust collecting groove 250, a first side notch of the dust collecting groove 250 is arranged close to the air inlet 210, the common chamber wall is located above the dust collecting groove 250, and when the air inlet 210 is closed, one end of the cover plate of the air inlet 210, which is far away from the common chamber wall, can abut against the first side notch. In particular, reference may be made to a dust chamber 200 located on the right side as shown in fig. 1. The left side notch of the dust collecting groove 250 is close to the air inlet 210, and when the air inlet 210 covers and closes the air inlet 210, the end of the air inlet 210, which is far away from the wall of the public chamber, also rotates to the position of the side notch. Moreover, since the wall of the public chamber is located above the notch, when the end of the cover plate of the air inlet 210, which is far away from the wall of the public chamber, rotates to the position of the notch on the side, the cover plate of the air inlet 210 just forms a downward-inclined shape. Therefore, the dust falling on the cover plate of the air inlet 210 can freely slide into the dust collecting groove 250.

Further, the dust collecting groove 250 has a second side notch opposite to the first side notch, and the inner wall of the dust removing chamber connected to the top end of the groove at the second side notch is a dust collecting wall extending from the second side notch obliquely upward. As shown in fig. 1, the dust falling on the right side of the dust collecting groove 250 can freely slide down into the dust collecting groove 250 from the inner wall of the partial dust removing chamber 200.

Further, in one specific example, the dust collector further comprises a dust bag 300, the dust bag 300 is detachably connected with the bottom of the dust collection groove 250, and the bottom of the dust collection groove 250 is provided with a through hole for communicating the dust collection groove 250 with the dust bag 300. The dust falling into the dust collecting groove 250 can fall into the dust collecting bag 300 through the through hole, and when the dust collecting bag 300 is full of dust, only the dust collecting bag 300 needs to be manually replaced without operating the inside of the dust collector.

In one specific example, a dust collection groove baffle 251 is further disposed in the dust removal chamber 200, and the dust collection groove baffle 251 is linked with the shaking motor 232. Specifically, when the vibration motor 232 starts to operate, the dust collecting groove blocking plate 251 is also opened, and the shaken off dust falls into the dust collecting groove 250 from the inside of the dust removing chamber 200 or the closed cover plate of the air inlet 210. More specifically, the dust collection groove blocking plate 251 may be a cover plate that rotates around a side slot, and rotates into the dust collection groove 250 when opened, or is overlappingly disposed on the cover plate of the air inlet 210, or is overlappingly disposed on the inner wall of the dust chamber 200. As shown in fig. 1, in the clean room 200 on the right side, the dust collection groove shutter 251 rotates around the notch on the side near the air intake 210 and is overlapped on the inner wall of the clean room 200. As another example, the dust collection groove shutter 251 may also be a shutter that can be retracted or extended.

The dust remover adopts the design of two independent and spaced dust removing chambers, can realize automatic switching of dust removing chamber operation, and realizes automatic dust removal, automatic cleaning and automatic dust collection of the dust removing chambers. Specifically, in the actual use process, the left-side dust removal chamber may be stopped, the right-side dust removal chamber may be started, and dust may be adsorbed on the mesh filter after the dust-containing exhaust gas enters the right-side dust removal chamber. After the net filter adsorbs the dust, can switch to left side clean room work, the air intake and the air outlet of right side clean room all present the closed condition, and the right side shakes and trembles the motor and begins to shake to get rid of the adsorbed dust on the net filter, and the dust is automatic to be taken in collection dirt recess, fall into the collection dirt bag. The process realizes automatic dust removal, automatic cleaning and automatic dust collection of the dust removal chamber, so that the dust remover becomes a full-automatic self-cleaning dust remover, and the supervision and use of manpower can be effectively reduced.
