Description

Technical Field

[0001] This utility model relates to the field of separator anti-clogging technology, specifically to an anti-clogging mechanism for a tar-ammonia pre-separator. Background Technology

[0002] A tar-ammonia separator is a primary cooling device for coke oven gas that uses gravity settling to separate coal from oil, ammonia, and tar residue. Commonly used types include mechanized ammonia clarification tanks and tar-ammonia separation tanks. However, for environmental reasons, newly built coking plants' gas purification systems now use tar-ammonia pre-separators and tar-ammonia separation tanks in sealed tanks instead of the original mechanized tar clarification tanks. The sealed tanks are equipped with a negative pressure recovery system at the top to effectively recover VOCs. The tar-ammonia pre-separator is equipped with a tar pressing pump to crush tar residue and prevent it from being carried into the subsequent tar-ammonia separation tank and clogging the equipment. However, in actual production, it has been found that the thick filter at the inlet of the tar pressing pump clogs frequently, requiring cleaning twice a week. Severe clogging increases the difficulty and time required for cleaning, affecting the efficiency of the tar-ammonia pre-separator and increasing the workload of workers. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, a tar-ammonia-water pre-separator anti-clogging mechanism is provided to solve the problems mentioned in the background technology.

[0004] To achieve the above objectives, an anti-clogging mechanism for a tar-ammonia pre-separator is provided, comprising: an anti-clogging component, the upper end of which is connected to the discharge port at the lower part of the tar-ammonia pre-separator body, and the lower end of which is connected to the inlet of a thick filter. The anti-clogging component consists of a housing, a lower mounting frame, filter strips, an upper mounting frame, and a sealing block. The upper surface of the housing is fixedly connected to a housing cover by a fixing plate and fastening bolts, while the inner cavity side of the housing is fixedly connected to the lower mounting frame by a positioning block. The lower mounting frame is fixedly connected to the upper mounting frame by a main bolt, and the lower surface of the upper mounting frame is symmetrically connected to filter strips. Cleaning ports are symmetrically opened on the side of the housing, and the cleaning ports are movably connected to the sealing block through a main sealing layer. The sealing block is fixedly connected to the mounting plate, and the mounting plate is fixedly connected to the outer side of the housing by auxiliary bolts.

[0005] Preferably, the box body has a rectangular parallelepiped structure, the lower surface of the box body has a frustum-shaped structure, and the two sets of cleaning ports opened on the same side of the box body are both rectangular in shape, while the main sealing layer fixedly connected inside the cleaning ports has a square cylindrical structure.

[0006] Preferably, a set of fixing plates is fixedly connected to the outer sides of the box body and the box cover, both sets of fixing plates are in the shape of a square, and the two sets of fixing plates are fixedly connected by fastening bolts that are evenly distributed.

[0007] Preferably, a main sealing ring is fixedly connected to the upper surface of the box body, and a secondary sealing ring is fixedly connected to the edge of the lower surface of the box cover. Both the main sealing ring and the secondary sealing ring have a U-shaped structure, while the cross-section of the main sealing ring has a convex shape and the cross-section of the secondary sealing ring has a concave shape.

[0008] Preferably, positioning blocks are symmetrically connected at the four corners of the inner side of the box. The positioning blocks have an L-shaped structure, and two sets of lower mounting frames are fixedly connected to the inner cavity of the box through the positioning blocks. Each set of lower mounting frames has four sets of positioning blocks fixedly connected to its lower surface, and the lower mounting frames have a U-shaped structure.

[0009] Preferably, the upper mounting frame and the lower mounting frame are matched in size, and multiple sets of filter strips are fixedly connected to the lower surface of the upper mounting frame through grooves at equal intervals. The filter strips are long strips with arc-shaped protrusions on the upper surface. The filter strips and the upper mounting frame are combined to form a U-shaped structure. At the same time, the filter strips in the two sets of upper mounting frames are distributed perpendicularly to each other, and the distance between adjacent filter strips is 12 cm.

[0010] Preferably, the mounting plate has a rectangular structure, and two sets of sealing blocks are fixedly connected to the surface of the mounting plate relative to the cleaning port. Both sets of sealing blocks have a cuboid structure. A secondary sealing layer is fixedly connected to the side of the mounting plate near the sealing blocks. The secondary sealing layer has a H-shaped structure. Meanwhile, two sets of pull plates fixedly connected to the other side of the mounting plate have a C-shaped structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: through the cooperation of the lower mounting frame, the upper mounting frame, the filter strip and the housing, the anti-clogging component can intercept large particles of slag, while small particles of tar slag enter the thick filter, thereby effectively reducing the clogging of the thick filter and reducing the cleaning difficulty of the thick filter. As a result, the cleaning frequency of the anti-clogging component is once a month, while the thick filter only needs to be flushed and emptied periodically, eliminating the need for manual opening and cleaning, and greatly reducing the workload of workers.

Detailed Implementation

[0017] Reference Figures 1 to 4 As shown, this utility model provides an anti-clogging mechanism for a tar-ammonia pre-separator, including: an anti-clogging component 2, the upper end of which is connected to the discharge port at the lower part of the tar-ammonia pre-separator body 1, and the lower end of which is connected to the inlet of the thick filter 3. The anti-clogging component 2 is composed of a housing 4, a lower mounting frame 6, filter strips 7, an upper mounting frame 8, and a sealing block 12. The upper surface of the housing 4 is fixedly connected to the housing cover by a fixing plate 10 and fastening bolts. The inner side of the housing 4 is fixedly connected to the lower mounting frame 6 by a positioning block 5. At the same time, the lower mounting frame 6 is fixedly connected to the upper mounting frame 8 by a main bolt. The lower surface of the upper mounting frame 8 is symmetrically connected to the filter strips 7. The side of the housing 4 is symmetrically provided with cleaning ports. The cleaning ports are movably connected to the sealing block 12 through a main sealing layer 15. The sealing block 12 is fixedly connected to the mounting plate 13. The mounting plate 13 is fixedly connected to the outer side of the housing 4 by auxiliary bolts.

[0018] In this embodiment, the material discharged from the lower outlet of the tar-ammonia pre-separator body 1 flows into the anti-clogging component 2 through a pipeline. The anti-clogging component 2, through multiple sets of filter strips 7 arranged in layers inside, can effectively intercept large particles of slag in the material, allowing small particles of tar slag to pass smoothly through the anti-clogging component 2 into the thick filter 3, thereby effectively reducing the probability of clogging of the thick filter 3 and reducing the cleaning frequency and difficulty of the thick filter 3. When the anti-clogging component 2 needs to be cleaned, the auxiliary bolts are removed first, and the fixed connection between the housing 4 and the mounting plate 13 is released. Then, the mounting plate 13 can be moved by pulling the pull plate 14. The mounting plate 13 can drive the two sets of sealing blocks 12 that are fixedly connected to simultaneously disengage from the two sets of cleaning ports opened on the side of the housing 4. Then, the workers can conveniently clean the large particles of slag intercepted on the upper surface of the two sets of upper mounting plates 13 through the two sets of cleaning ports, effectively reducing the cleaning difficulty and improving the cleaning efficiency.

[0019] As a preferred embodiment, the box 4 has a rectangular structure as a whole, the lower surface of the box 4 has a frustum-shaped structure, and the two sets of cleaning ports opened on the same side of the box 4 are both rectangular structures. At the same time, the main sealing layer 15 fixedly connected inside the cleaning port has a square cylindrical structure.

[0020] In this embodiment, as Figure 2 and Figure 3The main sealing layer 15 helps to enhance the sealing of the connection between the cleaning port and the sealing block 12, reducing the chance of accidental leakage inside the box 4. At the same time, the structure at the bottom of the box 4 helps to improve the efficiency of material flow.

[0021] In a preferred embodiment, a set of fixing plates 10 are fixedly connected to the outer sides of the box body 4 and the box cover, respectively. Both sets of fixing plates 10 are U-shaped structures, and the two sets of fixing plates 10 are fixedly connected by fastening bolts that are evenly distributed.

[0022] In this embodiment, as Figure 2 The setting of the fixing plate 10 can not only effectively enhance the stability of the connection between the box 4 and the box cover, but also facilitate the disassembly of the anti-blocking component 2, thereby helping to improve the loading and unloading efficiency of the internal structure of the anti-blocking component 2.

[0023] In a preferred embodiment, a main sealing ring 9 is fixedly connected to the upper surface of the housing 4, and a secondary sealing ring 11 is fixedly connected to the edge of the lower surface of the housing cover. Both the main sealing ring 9 and the secondary sealing ring 11 have a U-shaped structure, while the cross-section of the main sealing ring 9 has a convex shape and the cross-section of the secondary sealing ring 11 has a concave shape.

[0024] In this embodiment, as Figure 2 The main sealing ring 9 and the secondary sealing ring 11 have a mortise and tenon structure on opposite sides, which can effectively enhance the sealing performance of the contact surface between the main sealing ring 9 and the secondary sealing ring 11, and further enhance the sealing performance of the connection between the housing 4 and the cover.

[0025] As a preferred embodiment, positioning blocks 5 are symmetrically connected at the four corners of the inner side of the box 4. The positioning blocks 5 have an L-shaped structure, and two sets of lower mounting frames 6 are fixedly connected to the inner cavity of the box 4 through the positioning blocks 5. Four sets of positioning blocks 5 are fixedly connected to the lower surface of each set of lower mounting frames 6. At the same time, the lower mounting frames 6 have a U-shaped structure.

[0026] In this embodiment, as Figure 2 and Figure 3 The positioning block 5 helps to enhance the stability of the fixed connection between the housing 4 and the lower mounting frame 6, thereby helping to enhance the stability of the upper mounting frame 8 and filter strip 7 after installation.

[0027] In a preferred embodiment, the upper mounting frame 8 and the lower mounting frame 6 are matched in size. Multiple sets of filter strips 7 are fixedly connected to the lower surface of the upper mounting frame 8 through grooves at equal intervals. The filter strips 7 are elongated and have an arc-shaped protrusion on their upper surface. The filter strips 7 and the upper mounting frame 8 are combined to form a U-shaped structure. The filter strips 7 in the two sets of upper mounting frames 8 are distributed perpendicularly to each other, and the distance between adjacent filter strips 7 is 12 cm.

[0028] In this embodiment, as Figure 2 and Figure 3 The arc-shaped protrusions on the upper surface of the filter strip 7 can help enhance the impact resistance of the filter strip 7 and reduce the probability of the filter strip 7 bending and being damaged due to material impact. At the same time, the filter strips 7 adjacent to each other in the upper and lower parts of the housing 4 are arranged in a grid-like structure, which can effectively enhance the interception effect of the anti-clogging component 2 on long strip-shaped large particles of slag and reduce the probability of the thick material filter 3 being blocked.

[0029] In a preferred embodiment, the mounting plate 13 has a rectangular structure. Two sets of sealing blocks 12 are fixedly connected to the surface of the mounting plate 13 at the position opposite to the cleaning port. Both sets of sealing blocks 12 have a cuboid structure. A secondary sealing layer 16 is fixedly connected to the side of the mounting plate 13 near the sealing block 12. The secondary sealing layer 16 has a H-shaped structure. Meanwhile, two sets of pull plates 14 are fixedly connected to the other side of the mounting plate 13. Both have a C-shaped structure.

[0030] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The secondary sealing layer 16 can effectively enhance the sealing performance of the contact surface between the mounting plate 13 and the housing 4, and then work with the main sealing layer 15 to further enhance the sealing effect at the cleaning port of the housing 4, reducing the probability of accidental leakage of the anti-blocking component 2.

[0031] The anti-clogging mechanism of this utility model's tar-ammonia pre-separator, through the cooperation of the lower mounting frame 6, upper mounting frame 8, filter strip 7, and housing 4, enables the anti-clogging component 2 to effectively intercept large particles of slag, reducing the probability of large particles falling into the thick filter 3, thereby reducing the probability of the thick filter 3 being clogged, reducing the frequency of worker cleaning, reducing the difficulty of cleaning, and improving cleaning efficiency. At the same time, both the tar-ammonia pre-separator body 1 and the thick filter 3 are common brand models on the market.
