Description

Technical Field

[0001] This utility model relates to the field of dust removal device technology, specifically an explosion-proof dust removal device for a waste PCB board copper powder recycling system. Background Technology

[0002] In the process of processing waste PCB boards, copper powder is usually extracted from the waste PCB boards through physical, chemical or combined processes. However, during the process of recycling copper powder using a waste PCB board copper powder recycling system, some copper powder may escape during ventilation and other operations, resulting in a certain amount of dust in the working environment. Therefore, in order to improve the working environment and prevent dust explosions, dust removal devices are usually installed in the working area.

[0003] The explosion-proof dust removal device of the existing waste PCB copper powder recycling system usually uses an air pump to draw air, allowing the dust-laden air to enter the filter bag, where the copper powder is intercepted. However, after a period of use, the inside of the filter bag is easily contaminated with copper powder, affecting the normal filtration of the filter bag. At this time, the device needs to be opened and the filter bag needs to be removed for cleaning. When a lot of copper powder escapes in the working environment, frequent disassembly and cleaning of the filter bag may be required, which is not conducive to dust removal. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4In this embodiment of the present invention, an explosion-proof dust removal device for a waste PCB copper powder recycling system includes a collection module 100, an air extraction module 300, a collection cylinder 110, a conveying pipe 112 fixedly connected to the bottom of the collection cylinder 110, a collection cloth cylinder 130 inside the collection cylinder 110, a top plate 120 at the top of the collection cylinder 110, an air inlet pipe 121 fixedly connected to the top plate 120, and several support columns fixedly connected to the bottom of the collection cylinder 110 for support. The air inlet pipe 121 corresponds to the inside of the collection cloth cylinder 130, and the delivery pipe 112 corresponds to the space between the collection cloth cylinder 130 and the collection cylinder 110. The air extraction module 300 includes a housing and an air pump. The delivery pipe 112 extends into the housing, and the bottom end of the delivery pipe 112 is connected to the air inlet end of the air pump. Several positioning seats are fixedly connected to the top side of the collection cylinder 110 and the side of the top plate 120. Positioning screws are provided on two adjacent positioning seats. The two adjacent positioning seats are connected by the positioning screws, thereby fixing the top plate 120 to the top of the collection cylinder 110.

[0029] The bottom of the collecting cloth cylinder 130 is fixedly connected to a connecting pipe 133 that is slidably connected to the collecting cylinder 110. The bottom end of the connecting pipe 133 extends to the outside of the collecting cylinder 110, and a valve is provided inside the connecting pipe 133.

[0030] The top plate 120 is equipped with a cleaning module 200, which includes a drive shaft 220, several connecting mechanisms 230, two cleaning rods 240, and a power motor 250.

[0031] The drive shaft 220 is rotatably connected to the top plate 120. The bottom end of the drive shaft 220 extends into the collection cloth cylinder 130. Several connecting mechanisms 230 are all set on the connecting mechanisms 230. Two cleaning rods 240 are set on two adjacent connecting mechanisms 230. Several cleaning bristles are fixedly connected to the side of the cleaning rods 240. Several connecting mechanisms 230 are in pairs. The cleaning rods 240 are set on two adjacent sets of two connecting mechanisms 230. The cleaning rods 240 are arc-shaped and located inside the collection cloth cylinder 130. The output end of the power motor 250 is connected to the top of the drive shaft 220. The power motor 250 is set on the top of the top plate 120. A power box 210 is fixedly connected to the top surface of the top plate 120 on the side of the power motor 250. The power motor 250 is located inside the power box 210. The power box 210 can provide a certain degree of shielding for the power motor 250.

[0032] Specifically, air can be drawn from the delivery pipe 112 by an air pump. Air containing copper powder can enter the collection cylinder 110 through the air inlet pipe 121, then pass through the collection cloth cylinder 130. The air can pass through the collection cloth cylinder 130 and finally enter the air pump from the delivery pipe 112. The air pump can discharge the filtered air from the air outlet pipe, while the copper powder will be intercepted inside the collection cloth cylinder 130, thereby recovering the copper powder and reducing the possibility of dust explosion. During the copper powder recovery process, the drive shaft 220 can be rotated by the power motor 250. The drive shaft 220 can drive the two cleaning rods 240 to rotate through the corresponding connecting mechanism 230, so that the cleaning rods 240 drive the cleaning bristles to rotate. The cleaning bristles clean the inner wall of the collection cloth cylinder 130, brushing away as much copper powder as possible, thereby reducing the impact on the air passing through the collection cloth cylinder 130. This helps to reduce the frequency of removing the collection cloth cylinder 130 for cleaning and facilitates continuous dust removal.

[0033] After a certain amount of copper powder accumulates in the collection cloth cylinder 130, the valve in the connecting pipe 133 can be opened, and then the copper powder in the collection cloth cylinder 130 can be discharged through the connecting pipe 133. When it is necessary to thoroughly clean or replace the collection cloth cylinder 130, the positioning screw can be removed from the positioning seat, and then the top plate 120 and the cleaning module 200 can be removed from the collection cylinder 110. The inside of the collection cylinder 110 can be opened, and then the collection cloth cylinder 130 can be removed from the collection cylinder 110 for cleaning or replacement.

[0034] Example 1

[0035] like Figure 4 As shown, in this embodiment, the connecting mechanism 230 includes a fixed rod 231, a sliding rod 232, and a return spring 233;

[0036] The fixed rod 231 is fixedly connected to the drive shaft 220, and the sliding rod 232 is slidably connected to the fixed rod 231. The end of the sliding rod 232 is fixedly connected to the adjacent cleaning rod 240. The return spring 233 is fixedly connected to the inside of the fixed rod 231 and the sliding rod 232. The side of the sliding rod 232 is slidably connected to the inner side of the fixed rod 231. One end of the return spring 233 is fixed to the inner side of the fixed rod 231, and the other end of the return spring 233 is fixed to the end of the sliding rod 232. Under the action of the return spring 233, the position of the sliding rod 232 can be maintained, so that the top of the cleaning rod 240 is attached to the inner wall of the collection cloth cylinder 130, thus limiting the position of the collection cloth cylinder 130.

[0037] In practice, when the power motor 250 drives the transmission shaft 220 to rotate, the transmission shaft 220 can drive the fixed rod 231 to rotate, the fixed rod 231 can drive the sliding rod 232 to rotate, and the sliding rod 232 can drive the corresponding cleaning rod 240 to rotate. Under the action of the return spring 233, the cleaning bristles can be tightly attached to the inner wall of the collecting cloth cylinder 130, which helps to ensure the cleaning effect.

[0038] like Figure 1-3 As shown, in this embodiment, the connecting tube 133 is screwed into a limiting ring 134, and the bottom of the collecting cylinder 110 is screwed into a screw-in ring 111. The limiting ring 134 is located outside the collecting cylinder 110, and the bottom side of the limiting ring 134 is provided with a protruding edge. The bottom surface of the screw-in ring 111 abuts against the edge of the limiting ring 134. The position of the connecting tube 133 is restricted by the screw-in ring 111 and the limiting ring 134, preventing the connecting tube 133 from moving upward. In this way, the connecting tube 133 can tighten the bottom of the collecting cloth cylinder 130, so that the collecting cloth cylinder 130 remains open.

[0039] In practice, after inserting the connecting pipe 133 into the bottom of the collecting cylinder 110, the limiting ring 134 can be screwed onto the connecting pipe 133 from the bottom of the connecting pipe 133. Then, the screwing ring 111 can be rotated to move the screwing ring 111 downward, so that the bottom surface of the screwing ring 111 abuts against the edge of the limiting ring 134, limiting the limiting ring 134 and preventing the connecting pipe 133 from moving upward. This can tighten the bottom of the collecting cloth cylinder 130 and open the bottom of the collecting cloth cylinder 130.

[0040] Example 2

[0041] Based on Example 1, such as Figure 2 and Figure 3 As shown, in this embodiment, a first support ring 140 and a second support ring 150 are fixedly connected inside the collection tube 110. A fixed ring 131 and several circular rings 132 are fixedly connected to the collection cloth tube 130. The first support ring 140 is located at the top of the second support ring 150, and the fixed ring 131 is located at the top of the collection cloth tube 130. The bottom surface of the fixed ring 131 contacts the top surface of the first support ring 140, and the top surface of the second support ring 150 contacts the bottom surface of the circular rings 132 located at the bottom. The inner diameter of the first support ring 140 is larger than that of the circular rings 132. The diameter of the support ring is such that the bottom surface of the support ring 140 is fixedly connected to several limiting rods 141, which are fixedly connected to the support ring 150. The side of the limiting rods 141 contacts the side of the ring 132. The support ring 140 supports the fixed ring 131, and the support ring 150 supports the bottom ring 132. The fixed ring 131 and the several rings 132 keep the collection cloth tube 130 open, and the limiting rods 141 limit the position of the several rings 132, thereby restricting the position of the collection cloth tube 130.

[0042] A stop frame 122 is fixedly connected to the bottom surface of the top plate 120. The bottom surface of the stop frame 122 contacts the top surface of the fixing ring 131. The bottom end of the air intake pipe 121 corresponds to the inside of the stop frame 122. The stop frame 122 abuts against the fixing ring 131, thereby positioning the fixing ring 131 and limiting the position of the top of the fixing ring 131.

[0043] In specific implementation, support ring 140 can support fixed ring 131, and support ring 150 can support bottom ring 132, thereby supporting collection cloth cylinder 130. When cleaning rod 240 is inserted into collection cloth cylinder 130, it can abut against fixed ring 131, thereby limiting the position of fixed ring 131. After top plate 120 is placed on collection cylinder 110, abutting frame 122 can abut against the top surface of fixed ring 131, completely positioning fixed ring 131, thereby setting collection cloth cylinder 130 inside collection cylinder 110.

[0044] After removing the top plate 120 and the cleaning module 200 from the collection cylinder 110, the limiting ring 134 can be unscrewed from the connecting pipe 133. Then, the fixing ring 131 and the circular ring 132 can be moved upward. The circular ring 132 can move upward along the limiting rod 141 and pass through the inside of the support ring 140, thereby removing the collection cloth cylinder 130 and replacing it.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
