[0006] Therefore, the purpose of this utility model is to provide an anti-clogging gas dust filtration device. When the filtration device is in use, the inclined filter plate reduces the dust adsorbed on its surface. The filter plate is cleaned and the dust is discharged by back-blowing air, which reduces the situation of the filter plate being blocked by dust and improves the filtration effect of air dust.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A gas dust filtration device for preventing clogging, comprising: A filter box, wherein an air inlet channel and an air outlet channel are welded and fixed at both ends of the filter box, and a filter plate is fixed at an angle inside the filter box.

[0017] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] This utility model provides an anti-clogging gas dust filtration device. When the filtration device is in use, the inclined filter plate 108 reduces the dust adsorbed on its surface. The filter plate 108 is cleaned and the dust is discharged by back-blowing air, which reduces the situation of the filter plate 108 being blocked by dust and improves the filtration effect of air dust.

[0020] Figures 1-6 The diagram shown is an overall structural schematic of one embodiment of the anti-clogging gas and dust filtration device of this utility model. Please refer to [link / reference]. Figures 1-6 This embodiment of an anti-clogging gas and dust filtration device includes: The filter box 100 has an air inlet channel 104 and an air outlet channel 101 welded and fixed at both ends, and a filter plate 108 is fixed at an angle in the filter box 100. A fan 102 is embedded in both the air inlet channel 104 and the air outlet channel 101. The cleaning mechanism includes a cleaning brush 201 disposed in the filter box 100 and attached to the side wall of the filter plate 108, and a lead screw 202 rotatably mounted in the filter box 100 via a sealed bearing. The lead screw 202 is threaded into the protrusion 303 of the filter plate 108. A cleaning motor 200 connected to the lead screw 202 is fixed to the outer wall of the filter box 100. The width of the cleaning brush 201 is about one-tenth of the filter plate 108, so it will not affect the normal use of the filter plate 108. Two sets of sealing plates 302 are provided in the filter box 100, and a synchronous rotation mechanism is installed between the two sealing plates 302. The outer wall of the filter box 100 is provided with a positioning assembly for axially fixing the sealing plates 302. The air outlet duct 105 is fixed to the bottom of the filter box 100 between the sealing plate 302 and the filter plate 108, and a dust collection filter bag 106 is installed at the bottom of the air outlet duct 105. When the filter device is in use, the fans 102 in the air inlet channel 104 and the air outlet channel 101 rotate synchronously in the forward direction. Dust in the air is adsorbed by the filter plate 108. During the airflow, the dust on the inclined surface of the filter plate 108 is blown away, causing the dust to move downward on the surface of the filter plate 108, reducing the dust adsorbed on the surface of the filter plate 108 and cleaning the filter. When the filter plate 108 is closed, the sealing plate 302 is closed, and the fan 102 in the air outlet duct 101 reverses to blow air back onto the filter plate 108 to clean the dust. At the same time, the cleaning motor 200 drives the lead screw 202 to rotate, causing the cleaning brush 201 to clean the surface of the filter plate 108. The airflow is discharged from the air outlet duct 105, causing the dust to accumulate in the dust storage filter bag 106. The inclined filter plate 108 reduces the dust adsorbed on its surface. Blowing air back onto the filter plate 108 to clean the dust and discharge the dust reduces the situation of the filter plate 108 being blocked by dust and improves the filtration effect of air dust.

[0021] Combination Figures 1-6 The specific usage process of the anti-clogging gas dust filtration device of this embodiment is as follows: When the filtration device is in use, the fans 102 in the air inlet channel 104 and the air outlet channel 101 rotate synchronously in the forward direction. Dust in the air is adsorbed by the filter plate 108. During the airflow, the dust on the inclined surface of the filter plate 108 is blown away, causing the dust to move downward on the surface of the filter plate 108, reducing the dust adsorbed on the surface of the filter plate 108. When cleaning the filter plate 108, the sealing plate 302 is closed, and the fan 102 in the air outlet channel 101 reverses to blow air back on the filter plate 108 to clean the dust. At the same time, the cleaning motor 200 drives the lead screw 202 to rotate, causing the cleaning brush 201 to clean the surface of the filter plate 108. The airflow is discharged from the air outlet pipe 105, causing the dust to accumulate in the dust storage filter bag 106. The inclined filter plate 108 reduces the dust adsorbed on its surface. The back-blowing of the filter plate 108 to clean the dust and discharge the dust reduces the situation of the filter plate 108 being blocked by dust and improves the filtration effect of air dust.

[0022] Both the inlet duct 104 and the outlet duct 101 are fixed with protective nets 103. The protective nets 103 have large apertures to prevent dust from being blocked. A control valve is installed on the outlet duct 105. The top of the dust collection filter bag 106 is glued with a threaded connecting ring 107 that is inserted into the bottom of the outlet duct 105. After cleaning, the dust collection filter bag 106 is removed through the connecting ring 107 for cleaning. A rotating shaft 301 is fixedly inserted into the center of the sealing plate 302. Both ends of the rotating shaft 301 are rotatably inserted into the sealing bearing. In the filter box 100, the synchronous rotation mechanism includes a synchronous pulley 306 fixedly sleeved on one end of the rotating shaft 301 and a synchronous belt 305 meshing between the two synchronous pulleys 306. The other end of the rotating shaft 301 passes through the filter box 100 and has a screw hole. There are two sets of screw holes, and the included angle between the two sets of screw holes is 90 degrees. A knob 300 is fixed on one of the rotating shafts 301. The knob 300 drives one of the rotating shafts 301 to rotate. The synchronous pulleys 306 and the synchronous belt 305 drive the other rotating shaft 301 to rotate synchronously, causing the sealing plate 30 to rotate synchronously. 2. When rotated to a horizontal position, the fastening bolt 304 on the protrusion 303 is threaded into one of the screw holes of the rotating shaft 301 to keep the sealing plate 302 fixed. During dust removal, the fastening bolt 304 is unscrewed and the sealing plate 302 is rotated to a vertical position. The knob 300 is threaded into the other screw hole of the rotating shaft 301 to keep the sealing plate 302 fixed. The positioning assembly includes the protrusion 303 welded and fixed to the outer wall of the filter box 100 and the fastening bolt 304 installed on the top of the protrusion 303. The rotating shaft 301 is embedded with... In the protrusion 303, the bottom end of the fastening bolt 304 is threaded into the screw hole on the outer wall of the rotating shaft 301. A one-way baffle 400 is embedded and fixed at the end of the filter box 100 away from the filter plate 108. Multiple ventilation slots 402 are equally spaced on the one-way baffle 400. A one-way baffle plate 401 is bonded and fixed to the top wall of the ventilation slot 402. An arc-shaped groove is opened at the top of the one-way baffle plate 401. When the air flows, it blows the one-way baffle plate 401 to rotate upward along the arc-shaped groove. The one-way baffle plate 401 can prevent the air from flowing back. Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
