Description

Technical Field

[0001] The present invention relates to the technical field of photosensitive dry film production, and more specifically, to an exhaust gas treatment device for photosensitive dry film. Background Art

[0002] A large amount of waste gas is generated during the production process of photosensitive dry film. The existing technology uses a carbon barrel filter to filter and purify such waste gas. The carbon barrel is composed of two steel mesh cylinders nested together. Activated carbon particles are filled between the interlayers of the two straight steel mesh cylinders. The activated carbon particles absorb harmful substances in the waste gas to achieve the purpose of purifying the waste gas. In order to improve the purification efficiency, the activated carbon particles should be compacted in the interlayer. Since the interlayer is relatively narrow and long, when the activated carbon particles are replaced later, the activated carbon particles will be stuck in the interlayer and difficult to remove. Summary of the invention

[0003] In order to overcome the disadvantage that it is difficult to operate the replacement of activated carbon particles in the existing carbon barrel filter, the present invention provides an exhaust gas treatment device for photosensitive dry film.

[0004] The technical implementation scheme of the present invention is:

[0005] An exhaust gas treatment device for photosensitive dry film, comprising a box body, a connecting plate and a partition; the box body is fixedly connected with a connecting plate; the box body is bolted with a partition; it also comprises a connecting block, a cylinder, a wire mesh barrel 1, a ring 1, a spring, a wire mesh barrel 2, a ring 2 and a conveying assembly; a plurality of connecting blocks are fixedly connected to the connecting plate; each connecting block is fixedly connected with a cylinder; each cylinder is fixedly connected with a wire mesh barrel 1, and the wire mesh barrel 1 is in a truncated cone shape; a ring 1 is slidably connected to the outer surface of each cylinder; each cylinder is sleeved with a spring, one end of the spring is fixedly connected to the corresponding connecting block, and the other end of the spring is fixedly connected to the corresponding connecting block. The corresponding circular rings are fixedly connected; a wire mesh barrel two is fixedly connected to each circular ring one, and the wire mesh barrel two is in the shape of a truncated cone; a circular ring two is fixedly connected to each wire mesh barrel two, and the circular ring two is fixedly connected to the corresponding wire mesh barrel one; a cavity one is formed between the box body, the connecting plate and the partition; a cavity two is formed between the box body and the partition; a cavity three is formed between the adjacent wire mesh barrel one, circular ring one, wire mesh barrel two and circular ring two; a cavity four is formed on the inner side of the wire mesh barrel one, and the cavity four is connected to the cavity two; a conveying component is connected to the box body, and the conveying component is used to convey gas to cavity one, and the conveying component is used to discharge the gas in cavity two.

[0006] Furthermore, the conveying component includes a pipe 1 and a pipe 2; a plurality of pipes 1 are passed through the box body, and the pipes 1 are connected to the cavity 1; a pipe 2 is passed through the box body, and the pipe 2 is connected to the cavity 2.

[0007] Furthermore, a side of the box body close to the second pipe is funnel-shaped.

[0008] Furthermore, it also includes a handle; each connecting block is fixedly connected to a handle.

[0009] Furthermore, it also includes elastic blocks; a plurality of elastic blocks are fixedly connected to the connecting plate; every four elastic blocks are set as a group, and each group of elastic blocks is located on the outer side of the corresponding wire mesh barrel two.

[0010] Furthermore, it also includes a circular ring three; each circular ring two is fixedly connected to a circular ring three.

[0011] Furthermore, it also includes a circular ring four; each circular ring two is fixedly connected to a circular ring four, and the circular ring four is fixedly connected to the corresponding wire mesh barrel one.

[0012] Furthermore, a side of the ring 4 away from the ring 2 is set as a frustum.

[0013] Furthermore, it also includes protrusions; each ring is fixedly connected with a plurality of protrusions.

[0014] Furthermore, the surface of the box is coated with an anti-corrosion layer.

[0015] Beneficial effects of the present invention:

[0016] 1. The wire mesh barrel 1 and the wire mesh barrel 2 are both set in a truncated cone shape. When replacing the activated carbon, compared with the existing straight-cylindrical wire mesh, the manual operation only needs to move the wire mesh barrel 2 upward to expand the cavity 3 so that the activated carbon particles therein can be loosened and fall, thereby realizing convenient material removal. Compared with manually using tools to pull out the activated carbon particles pressed in the cavity 3, the activated carbon replacement efficiency is greatly improved;

[0017] Second, in the process of taking out the connecting block and the parts thereon from the box, the activated carbon particles inside the cavity three can be pre-moved to a loose state by the elastic block, which is beneficial to improving the efficiency of taking out the activated carbon particles. At the same time, since the diameter of the wire mesh barrel two is set to increase from left to right, the squeezing force of the elastic block on the wire mesh barrel two increases gradually during the process of manually taking out the connecting block and the parts thereon from the box, and the activated carbon particles on the right side of the cavity three are fully pressed loose, further improving the efficiency of taking out the activated carbon particles. At the same time, the elastic block used to squeeze the activated carbon particles is also used to support and guide the wire mesh barrel two, so that when manually pulling the handle to take out the connecting block and the parts thereon, there is no need to deliberately keep the connecting block and the parts thereon balanced, which is beneficial to improving the convenience of manual operation;

[0018] 3. A circular ring is set at the bottom of the wire mesh to prevent the wire mesh from being deformed in the longitudinal direction, which is beneficial to improving stability. When the wire mesh barrel is manually turned over, the activated carbon can slide off the round table surface of the circular ring, avoiding the interference of the circular ring with the activated carbon pouring and cleaning operation.

DETAILED DESCRIPTION

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings. Example 1

[0027] An exhaust gas treatment device for photosensitive dry film, such as Figure 1-Figure 5As shown, it includes a box body 1, a connecting plate 2 and a partition 3; the box body 1 is bolted with a connecting plate 2, and the box body 1 is set to be made of alloy; the box body 1 is bolted with a partition 3; it also includes a connecting block 4, a cylinder 5, a wire mesh barrel 6, a ring 7, a spring 8, a wire mesh barrel 9, a ring 10 and a conveying component; sixteen connecting blocks 4 are bolted to the connecting plate 2; each connecting block 4 is bolted with a cylinder 5; each cylinder 5 is bolted with a wire mesh barrel 6, and the wire mesh barrel 6 is in the shape of a truncated cone; the outer surface of each cylinder 5 is slidably connected with a ring 7; each cylinder 5 is sleeved with a spring 8, one end of the spring 8 is fixedly connected to the corresponding connecting block 4, and the other end of the spring 8 is fixedly connected to the corresponding connecting block 4 The corresponding circular ring 1 7 is fixedly connected, and the spring 8 is set to an alloy material; each circular ring 17 is bolted to a wire mesh barrel 2 9, and the wire mesh barrel 2 9 is in the shape of a truncated cone; each wire mesh barrel 2 9 is bolted to a circular ring 2 10, and the circular ring 2 10 is bolted to the corresponding wire mesh barrel 1 6; a cavity 1 91 is formed between the box body 1, the connecting plate 2 and the partition 3; a cavity 2 92 is formed between the box body 1 and the partition 3; a cavity 3 93 is formed between the adjacent wire mesh barrels 1 6, circular ring 1 7, wire mesh barrels 2 9 and circular ring 2 10, and the activated carbon particles are manually loaded into the cavity 3 93; a cavity 4 94 is formed on the inner side of the wire mesh barrel 1 6, and the cavity 4 94 is connected to the cavity 2 92; a conveying component is connected to the box body 1.

[0028] The conveying component includes a pipe 1 201 and a pipe 202; two pipes 1 201 are passed through the box body 1, and the pipe 1 201 is connected to the cavity 1 91, and the pipe 1 201 is set to a plastic material; the box body 1 is passed through a pipe 202, and the pipe 2 202 is connected to the cavity 2 92. The exhaust gas flows from the pipe 1 201 into the cavity 1 91, and then passes through the activated carbon in the cavity 3 93 and flows into the cavity 4 94, and then flows from the cavity 4 94 into the cavity 2 92, and finally is discharged from the pipe 2 202.

[0029] The side of the box body 1 close to the second pipe 202 is funnel-shaped for guiding the air.

[0030] It also includes a handle 203; each connection block 4 is bolted with a handle 203, and the connection block 4 can be pulled manually by gripping the handle 203, making it more convenient to apply force.

[0031] First, the external air inlet pipe is manually connected to pipe one 201, and the external air outlet pipe is connected to pipe two 202. During purification, the exhaust gas is transported to pipe one 201 through the external air inlet pipe, and the exhaust gas flows into cavity one 91 through pipe one 201, and then the exhaust gas passes through the small holes on wire mesh barrel two 9 and flows into cavity three 93, and then passes through the small holes on wire mesh barrel one 6 and flows into cavity four 94, and then flows from cavity four 94 into cavity two 92, and finally flows from pipe two 202 into the external air outlet pipe. Cavity three 93 is filled with activated carbon particles. In this process, the exhaust gas will flow through the activated carbon layer in cavity three 93, and the harmful substances in the exhaust gas will be absorbed by the activated carbon layer to achieve the exhaust gas purification effect.

[0032] When replacing the activated carbon, the bolts on the connecting block 4 are manually unscrewed, and then the handle 203 is pulled to move to the left, and the handle 203 drives the connecting block 4 and the parts thereon to move to the left, so that the connecting block 4 and the parts thereon are taken out of the box body 1, and then the ring 2 10 is disassembled, and then the wire mesh barrel 2 9 is manually erected vertically, and the connecting block 4 is facing upward, and then the ring 1 7 is manually driven to move upward, and the ring 1 7 compresses the spring 8, and the ring 1 7 drives the wire mesh barrel 2 9 to move upward. At this time, the positional relationship between the wire mesh barrel 1 6 and the wire mesh barrel 2 9 is as shown in FIG. Figure 5 As shown, the positions of the wire mesh barrel 2 9 and the wire mesh barrel 1 6 are changed, so that the width of the cavity 3 93 is changed from h1 to h2, that is, the width of the cavity 3 93 becomes larger, thereby causing the activated carbon particles clamped in the cavity 3 93 to loosen and fall, thereby realizing convenient material retrieval. When in use, the wire mesh barrel 1 6 and the wire mesh barrel 2 9 are both set to be in a truncated cone shape. When performing the activated carbon replacement operation, compared with the existing straight-cylindrical wire mesh, manual labor only needs to move the wire mesh barrel 2 9 upwards to expand the cavity 3 93 so that the activated carbon particles therein can loosen and fall, thereby realizing convenient material retrieval. Compared with manually using tools to pull out the activated carbon particles compressed in the cavity 3 93, the activated carbon replacement efficiency is greatly improved. Example 2

[0033] On the basis of Example 1, Figure 3 and Figure 4 As shown, it also includes an elastic block 204; a plurality of elastic blocks 204 are fixedly connected to the connecting plate 2; every four elastic blocks 204 are set as a group, and each group of elastic blocks 204 are located on the outside of the corresponding wire mesh barrel 2 9, and the wire mesh barrel 2 9 is supported by the elastic blocks 204.

[0034] It also includes a circular ring 3 205; each circular ring 2 10 is bolted with a circular ring 3 205.

[0035] The activated carbon particles filled in the relatively narrow cavity three 93 will produce a "self-supporting particle medium" phenomenon, which makes it difficult to pour out the activated carbon particles in the cavity three 93. During the process of taking out the connecting block 4 and the parts thereon from the casing 1, the wire mesh barrel two 9 slides to the left on the inner side of the four elastic blocks 204. During this process, the elastic blocks 204 exert elastic force on the wire mesh barrel two 9, so that the wire mesh barrel two 9 is concave inward, squeezing the activated carbon particles in the cavity three 93, thereby loosening the activated carbon particles that are tightly stuck together and destroying the self-supporting structure between the activated carbon particles to facilitate the removal operation. When in use, during the process of taking out the connecting block 4 and the parts thereon from the casing 1, the activated carbon particles inside the cavity three 93 can be pre-moved to a loose state by the elastic blocks 204, which is beneficial to improving the efficiency of removing the activated carbon particles.

[0036] Since the right side of cavity three 93 is filled with relatively more activated carbon particles, the elastic block 204 needs to generate a greater pressure to loosen the activated carbon particles filled on the right side of cavity three 93. Therefore, the diameter of wire mesh barrel two 9 increases from left to right, so that the wire mesh barrel two 9 continues to squeeze the elastic block 204 during the leftward movement, and the squeezing degree gradually increases, so that the elastic force generated by the elastic block 204 on the wire mesh barrel two 9 gradually increases, and then the squeezing degree of the activated carbon particles gradually increases, so that the activated carbon particles on the right side of cavity three 93 can be fully loosened. When in use, since the diameter of wire mesh barrel two 9 is set to increase from left to right, during the process of manually removing the connecting block 4 and the parts thereon from the box body 1, the squeezing force of the elastic block 204 on the wire mesh barrel two 9 increases, so that the activated carbon particles on the right side of cavity three 93 are fully loosened, and the efficiency of removing the activated carbon particles is further improved.

[0037] After the activated carbon is replaced, the connecting block 4 and the parts thereon are inserted to the right into the housing 1. At this time, the circular ring 3 205 passes through the middle of the gap between the four elastic blocks 204, and then guides the wire mesh barrel 2 9 to move to the middle of the gap between the elastic blocks 204. During this process, the elastic block 204 produces an adaptive deformation, and the connecting block 4 is manually pushed to the right until the connecting block 4 contacts the connecting plate 2. At this time, the circular ring 3 205 is just inserted into the partition 3, and the replacement operation is completed. When in use, the elastic block 204 used to squeeze the activated carbon particles is also used to support and guide the wire mesh barrel 2 9, so that when the handle 203 is manually pulled to take out the connecting block 4 and the parts thereon, there is no need to deliberately keep the connecting block 4 and the parts thereon balanced, which is conducive to improving the convenience of manual operation. Example 3

[0038] On the basis of Example 2, Figure 5As shown, it also includes a circular ring four 206; each circular ring two 10 is bolted with a circular ring four 206, and the circular ring four 206 is fixedly connected to the corresponding wire mesh barrel one 6, and the wire mesh barrel one 6 is supported by the circular ring four 206.

[0039] The side of the ring four 206 away from the ring two 10 is set as a frustum surface for guiding the activated carbon.

[0040] It also includes a protrusion 207; two protrusions 207 are welded on each ring 7, and the ring 7 can be pulled manually by holding the protrusion 207, making it more convenient to apply force.

[0041] The surface of the box body 1 is coated with an anti-corrosion layer.

[0042] When taking out the activated carbon particles in the cavity three 93, it is necessary to stand the wire mesh barrel 6 on the ground. During this process, the reaction force of manually pulling the ring 7 upward and the gravity of the connecting block 4 and the parts thereon act on the lower end of the wire mesh barrel. The rigidity of the wire mesh is relatively low, resulting in low stability. Therefore, a ring four 206 is provided at the lower part of the wire mesh to prevent the wire mesh from being deformed in the longitudinal direction, which is beneficial to improving stability. At the same time, the lower side of the ring four 206 is also supported on the ground, which increases the ground contact area and further improves stability.

[0043] During the process of pouring activated carbon into cavity three 93, a small amount of activated carbon will fall into cavity four 94. After closing ring two 10, the activated carbon remaining in cavity four 94 is poured out manually by flipping wire mesh barrel one 6. At this time, ring four 206 will intercept the activated carbon and interfere with the pouring operation of the activated carbon. Therefore, the side of ring four 206 away from ring two 10 is set as a frustum surface, so that when the wire mesh barrel one 6 is manually flipped, the activated carbon can slide from the frustum surface of ring four 206, avoiding the interference of ring four 206 with the pouring and cleaning operation of the activated carbon.

Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
