It generally removes particulate matter from the air through multi-stage filtration. This process is usually carried out from large to small according to the size of the particles. This graded filtration method is conducive to gradually purifying the air and improving filtration efficiency.

[0004] At present, the filtration system of the dust-free workshop needs to be shut down regularly according to the filtration situation during continuous operation, and the filter plate needs to be replaced to avoid the accumulation of particles on the filter plate and affect the filtration efficiency.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , an air purification device for a dust-free workshop, comprising a filtering mechanism 1, an inlet mechanism 2 and a cleaning mechanism 3, the filtering mechanism 1 comprising a filtering chamber 103 with an inlet 101 and an outlet 102 at the bottom, the filtering chamber 103 being an annular structure and five double filter plates 104 being arranged on the filtering chamber 103, the double filter plates 104 being distributed along the circumference of the filtering chamber 103 and penetrating the filtering chamber 103 in a radial direction, the inlet 101 and the outlet 102 being arranged between adjacent double filter plates 104 and a partition plate 106 being arranged between the inlet 101 and the outlet 102, after entering from the inlet 101, the air passes through the double filter plates 104 in sequence along the circumference of the filtering chamber 103 and finally flows out from the outlet 102, the double filter plates 104 filter out the particles in the air in sequence from large to small according to the size of the particles in the air, thereby ensuring the efficiency and effect of the filtration.

[0032] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The double filter plate 104 includes a movable frame 124 symmetrically provided with filter bodies 114, the filter bodies 114 are filter nets, and the symmetrical filter bodies 114 are distributed along the radial direction of the filter cavity 103, and the movable frame 124 penetrates the filter cavity 103 in the radial direction and is slidably connected to the filter cavity 103, such as Figure 2 As shown, the movable frame 124 reciprocates along the radial direction of the filter cavity 103 to switch the filter body 114 in the filter cavity 103 to ensure that the filter body 114 in the filter cavity 103 is in a reliable filtering state.

[0033] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The cleaning mechanism 3 includes a cleaning cover 31 with a sealing cover arranged on the filter chamber 103, and a cleaning assembly 32 for cleaning the filter body 114. The cleaning cover 31 is an annular structure and is coaxially arranged with the filter chamber 103. On the one hand, the cleaning cover 31 forms an anti-leakage area outside the filter chamber 103, which effectively prevents air from entering the filter chamber 103 and entering the dust-free workshop again without being filtered. On the other hand, the cleaning cover 31 and the filter chamber 103 together constitute two cleaning areas 34 of annular structure. Figure 2 and Figure 3 As shown, one of the cleaning areas 34 is located on the inner ring side of the filter chamber 103, and the other cleaning area 34 is located on the outer ring side of the filter chamber 103. The cleaning components 32 are respectively located in the cleaning areas 34. The two filter bodies 114 on the same movable frame 124 always keep one in the filter chamber 103 for filtering, and the other in the cleaning area 34. The filter body 114 will complete the cleaning and removal of surface particles in the cleaning area 34 and maintain a clean state to enter the filter chamber 103 for filtering. When the filter body 114 in the filter chamber 103 needs to be replaced, the movable frame 124 is slid to allow the filter body 114 originally in the cleaning area 34 to enter the filter chamber. The filtration work is carried out in 103, and the filter body 114 originally in the filter cavity 103 enters another cleaning area 34, where the filter body 114 completes the cleaning of particulate matter and remains in a clean state waiting for the next replacement. The entire replacement and cleaning process does not require downtime and waiting, and the replacement and cleaning of the filter body 114 are completed in a relatively sealed environment, ensuring the stability of continuous filtration of the filtration system while ensuring the cleanliness of the air in the dust-free workshop, avoiding the situation where production interruption or increased defective product rate caused by reduced air cleanliness, and there is no need to manually replace the filter body 114, so that the air purification system can operate continuously and stably in an automated manner.

[0034] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The movable frame 124 is provided with an outer sealing head 134, an inner sealing head 144, a movable sealing part 154 and a tightening assembly 164. The outer sealing head 134 and the inner sealing head 144 are symmetrically distributed, and the symmetrical inner sealing head 144 and the symmetrical outer sealing head 134 are fixedly connected to the movable frame 124, and the symmetrical inner sealing head 144 is located between the symmetrical filter bodies 114, and the symmetrical outer sealing head 134 is located outside the filter cavity 103 and is respectively located on the inner ring side and the outer ring side of the filter cavity 103, and the movable sealing parts 154 are symmetrically distributed up and down and are respectively connected to the top and the bottom of the movable frame 124, and the movable sealing parts 154 are all connected to the movable frame 124 for sliding up and down. When the movable frame 124 is in a stationary state, one of the outer sealing heads 134 is in close contact with the filter cavity 103 from the outside, and one of the inner sealing heads 144 is in close contact with the filter cavity 103 from the inside, such as Figure 3 As shown, the outer sealing head 134 on the outer ring side of the filter chamber 103 is in close contact with the filter chamber 103 from the outside, and the inner sealing head 144 close to the inner ring side of the filter chamber 103 is in close contact with the filter chamber 103 from the inside, and the movable sealing part 154 is in close contact with the filter chamber 103 from the upper and lower sides of the movable frame 124 under the pressure of the pressing component 164. On the one hand, the filter chamber 103 has a higher sealing performance, and on the other hand, the double-piece filter plate 104 is sealed and connected with the filter chamber 103, so that the overall filtration system has a higher sealing performance. During the movement of the movable frame 124, the pressing component 164 releases the pressing work on the movable sealing part 154, reduces the friction between the movable sealing part 154 and the filter chamber 103, and is beneficial to the smooth movement of the movable frame 124 and the effectiveness of repeated sealing of the movable sealing part 154.

[0035] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The pressing assembly 164 includes a sliding rod 1642 fixedly connected with a plurality of trapezoidal blocks 1641 and a connecting block 1644 with a plurality of trapezoidal grooves 1643. The sliding rod 1642 is symmetrically distributed up and down and slidably connected to the moving frame 124 and corresponds to the movable close-fitting member 154 one by one. The trapezoidal blocks 1641 correspond to the trapezoidal grooves 1643 one by one. The connecting block 1644 is fixedly connected to the movable close-fitting member 154. The sliding rod 1642 is moved along the filter chamber 103. The sliding rod 1642 is radially slidable, and both ends of the sliding rod 1642 are fixedly connected with abutting ends 1645, which are respectively located at the inner ring side and the outer ring side of the filter chamber 103. When the filter body 114 close to the outer ring side of the filter chamber 103 is located in the filter chamber 103 for filtering, the abutting end 1645 located at the inner ring side of the filter chamber 103 abuts against the cleaning cover 31. At this time, the trapezoidal block 1641 abuts against the corresponding trapezoidal groove 1643 in the direction of the outer ring side. Figure 6 As shown, the movable sealing member 154 is tightly pressed against the filter chamber 103 through the cooperation of the trapezoidal block 1641 and the trapezoidal groove 1643. Then, when the movable frame 124 slides toward the outer ring side, the abutting end 1645 on the inner ring side is separated from the cleaning cover 31, releasing the abutting state of the movable sealing member 154, reducing the friction between the movable sealing member 154 and the filter chamber 103, and facilitating the smooth movement of the movable frame 124. Then, when the filter body 114 originally located on the outer ring side enters the filter chamber 103 for filtering, the abutting end 1645 on the outer ring side abuts against the cleaning cover 31, causing the trapezoidal block 1641 to abut against the trapezoidal groove 1643 toward the inner ring side, thereby causing the movable sealing member 154 to abut against the filter chamber 103.

[0036] See also Figure 2 , Figure 4 , Figure 7 and Fig.11 A close-contact roller 105 is rotatably provided on the filter chamber 103. When the filter body 114 moves with the moving frame 124, the close-contact roller 105 contacts and rotates with the filter body 114 during the movement, and the rotation direction of the close-contact roller 105 close to the filter body 114 is the same as the moving direction of the filter body 114. When the filter body 114 moves toward the outer wall of the filter chamber 103, the close-contact roller 105 contacts and rotates with the filter body 114. On the one hand, the contact between the close-contact roller 105 and the filter body 114 can reduce the gap generated during the replacement of the filter body 114, thereby effectively reducing the air outflow from the filter chamber 103. On the other hand, the rotating close-contact roller 105 can effectively avoid scraping off the particles gathered on the surface of the filter body 114 during the contact with the filter body 114, so that the particles are separated from the filter body 114 and remain in the filter chamber 103, thereby increasing the pressure of subsequent filtration.

[0037] See also Figure 2 , Figure 4 , Figure 8 and Fig.11 The filter chamber 103 is provided with a control assembly 107 for controlling the rotation of the close contact roller 105. The control assembly 107 includes a connecting frame 117 fixedly connected to the moving frame 124, a gear assembly 127 rotatably arranged on the filter chamber 103, and a rack 137 for controlling the rotation of the close contact roller 105 through the gear assembly 127. The rack 137 is slidably connected to the filter chamber 103 and fixedly connected to the connecting frame 117. Figure 8 As shown, during the movement of the moving frame 124, the rack 137 and the connecting frame 117 move synchronously with the moving frame 124, and the rack 137 drives the close contact roller 105 to rotate through the gear assembly 127, as shown in FIG. Figure 8 As shown, the gear assembly 127 includes five gears meshingly connected in sequence, wherein the first and last two gears have the same diameter and are coaxially fixedly connected to the two close-contact rollers 105 on the same side of the moving frame 124 through a connecting shaft 147, and any one of the five meshing gears is coaxially connected with a gear meshing with the rack 137, and the gear is meshingly connected with the rack 137, thereby driving the close-contact roller 105 to rotate when the rack 137 moves with the moving frame 124.

The transfer chamber 21 is located below the side cover 311 and is connected to the inlet 101. A connecting pipe 23 is connected between the suction port 22 and the transfer chamber 21. The connecting pipe 23 is distributed along the circumference of the filter chamber 103. The cleaning mechanism 3 also includes a scraping assembly 33. The scraping assembly 33 includes a moving part 332 provided with a plurality of scraping rings 331. The scraping rings 331 are evenly distributed along the circumference of the connecting pipe 23. The moving part 332 reciprocates in the axial direction of the connecting pipe 23. In the process of replacing the filter body 114, the moving part 332 reciprocates to make the scraping ring 331 move along the circumference of the connecting pipe 23. It moves along the inner wall of the connecting pipe 23, and scrapes the particles attached to the inner wall of the connecting pipe 23 during the movement, thereby increasing the activity of the particles, so that the particles can fully flow into the filter chamber 103 with the flowing air for filtration, thereby avoiding the deposition of particles in the connecting pipe 23 and affecting the conveying volume of the connecting pipe 23 and affecting the filtration efficiency and effect of the filtration system, wherein the scraper ring 331 is fixedly connected to the moving part 332 through the connecting bracket 333, and the connecting bracket 333 is V-shaped, and the connecting bracket 333 forms a triangular connecting support area between the moving part 332 and the scraper ring 331, which can effectively improve the stability of the scraper ring 331 during the reciprocating movement.
