Description

Technical Field

[0001] The utility model belongs to the technical field of coal chemical processing equipment, in particular to a coal chemical separation tower. Background Art

[0002] Coal chemical industry refers to the process of using coal as raw material, converting coal into gas, liquid and solid products or semi-products through chemical processing, and further processing them into a series of chemical products. In the process of coal chemical industry, wastewater containing coal slag will be generated. If the wastewater is discharged directly, it will pollute the environment, and the coal slag in the wastewater cannot be recycled, resulting in a waste of resources.

[0003] In response to the above technical problems, the applicant has retrieved some prior art, such as the patent publication number CN222075980U, whose main technical means is to set a number of separation parts at equal intervals inside the separation cabinet, and the liquid inlet pipe adds the coal chemical wastewater particles into the separation cabinet. Through the separation parts with different separation apertures, the coal chemical particles can be graded and separated, and the separation effect can be improved. Moreover, through the design of the separation parts, by controlling the mesh gap between the first separation mesh plate and the second wind mesh plate, the separation of coal chemical particles of different sizes can be adjusted to improve the separation applicability. After the analysis of the applicant, the disadvantage of this technical solution is that the above-mentioned separation parts are easily blocked by coal chemical particles during use, thereby reducing the classification effect, so that a large number of coal chemical particles on the blocked separation parts cannot be classified, thereby reducing the separation effect.

[0018] The beneficial effects of the utility model are:

[0019] 1. In the utility model, the filter holes on the upper filter plate are cleaned by a cleaning brush. At the same time, the wedge-shaped groove on the cleaning brush contacts the wedge-shaped block. Since there is power when the cleaning brush rotates, the wedge-shaped block drives the upper filter plate and the lower filter plate to move downward, and the elastic member is compressed. When the wedge-shaped groove on the cleaning brush passes over the wedge-shaped block, the wedge-shaped block is released from restriction, and the elastic member rebounds at this time, so that the upper filter plate and the lower filter plate return to their original positions. The upper filter plate and the lower filter plate will shake in this process, which can make the coal slag blocked in the filter hole continue to fall through the filter hole. With the cleaning of the cleaning brush, the coal slag is further effectively prevented from blocking the filter hole, and the blockage of the filter hole is effectively prevented from affecting the passage of other coal slag, thereby improving the separation effect.

[0020] 2. In the utility model, when the lower filter plate moves downward, the fixing rod moves along the rotating groove, so that the lower filter plate rotates a certain angle while moving downward, so that the filter holes on the upper filter plate and the lower filter plate are misaligned, so that larger coal slag can be effectively prevented from being stuck in the filter holes on the upper filter plate, thereby effectively preventing the coal slag from blocking the filter holes on the upper filter plate; when the lower filter plate rotates, since the filter holes on the upper filter plate and the lower filter plate are misaligned, the coal slag originally blocked in the filter holes of the upper filter plate will be squeezed by the edge of the filter holes on the lower filter plate, thereby crushing the coal slag and causing the coal slag to fall out of the filter holes, thereby effectively preventing the coal slag from blocking the filter holes on the upper filter plate and improving the separation effect;

[0021] 3. In the utility model, during the rotation of the cleaning brush, the inclined block slowly approaches the guide plate and enters the guide groove. Since the inclined block rotates with the cleaning brush, the inclined block is always in a horizontal plane, and since the inclined block moves along the guide groove, the guide plate slowly moves upward. During the upward movement of the guide plate, the sealing plate is driven to move upward, thereby opening the discharge channel. At this time, the coal slag separated by the upper filter plate will be discharged through the discharge channel; the inclined block intermittently enters the guide groove, and the intermittent discharge of the coal slag can effectively avoid excessive accumulation of coal slag to reduce the separation effect of the upper filter plate.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1-Figure 3 As shown, a coal chemical separation tower comprises a tower body 1, a feed hopper 10, a driving member 2 and a rotating rod 3, and the separation tower further comprises:

[0031] The upper filter plate 4 is provided with a plurality of upper filter plates 4 which are evenly spaced and movably mounted on the outer periphery of the rotating rod 3;

[0032] A lower filter plate 5, a plurality of lower filter plates 5 with equal spacing are movably installed on the outer periphery of the rotating rod 3, the lower filter plate 5 is located below the upper filter plate 4, and a plurality of elastic members 31 are also arranged on the outer periphery of the rotating rod 3, the top of the elastic member 31 is against the bottom of the lower filter plate 5;

[0033] Cleaning brush 6: A plurality of cleaning brushes 6 are installed on the periphery of the rotating rod 3, and the cleaning brushes 6 are against the top of the upper filter plate 4;

[0034] Wedge blocks 42, a plurality of wedge blocks 42 are arranged on the outer edge of the top of the upper filter plate 4, the wedge blocks 42 are in the path of the cleaning brush 6, and wedge grooves 61 are provided at both ends of the cleaning brush 6. When the wedge grooves 61 contact the wedge blocks 42, the wedge grooves 61 coincide with the inclined surfaces of the wedge blocks 42, and the power brought by the rotation of the cleaning brush 6 causes the upper filter plate 4 and the lower filter plate 5 to move downward.

[0035] In one case of this embodiment, the driving member 2 may be a motor or a member capable of driving the rotating rod 3 to rotate; the elastic member 31 may be a spring or other elastically retractable member.

[0036] In actual application of this embodiment, the wastewater generated by the coal chemical industry enters the tower body 1 through the feed hopper 10, and the wastewater continues to flow downward through the upper filter plate 4 and the lower filter plate 5, while the coal slag will be blocked by the upper filter plate 4, thereby achieving the purpose of separation. In the separation process, some coal slag will be blocked in the filter holes of the upper filter plate 4, which will block other smaller-sized coal slag from passing through the filter holes, resulting in a large amount of coal slag accumulated on the upper filter plate 4; at this time, the driving member 2 is started to make the rotating rod 3 drive the cleaning brush 6 to rotate, and the cleaning brush 6 can effectively clean the coal slag blocked in the filter hole to the upper filter plate 4 or directly pass the coal slag through the filter hole, effectively avoiding the blockage of the filter hole affecting the passage of other coal slag, thereby improving the separation effect;

[0037] During the rotation of the cleaning brush 6, the wedge-shaped groove 61 on the cleaning brush 6 contacts the wedge-shaped block 42. Since there is power when the cleaning brush 6 rotates, the wedge-shaped block 42 drives the upper filter plate 4 and the lower filter plate 5 to move downward, and the elastic member 31 is compressed. When the wedge-shaped groove 61 on the cleaning brush 6 passes over the wedge-shaped block 42, the restriction of the wedge-shaped block 42 is released, and the elastic member 31 rebounds, so that the upper filter plate 4 and the lower filter plate 5 return to their original positions. The upper filter plate 4 and the lower filter plate 5 will shake in this process, which can make the filter plate 4 and the lower filter plate 5 blocked. The coal slag in the filter holes continues to fall through the filter holes, and the cleaning with the cleaning brush 6 can further effectively prevent the coal slag from clogging the filter holes, and effectively prevent the filter holes from being blocked and affecting the passage of other coal slag, thereby improving the separation effect; in addition, when the wastewater flows downward from the feed hopper 10, the wastewater will bring a certain impact to the upper filter plate 4 when it contacts the upper filter plate 4, causing the upper filter plate 4 and the lower filter plate 5 to move downward, compressing the elastic member 31, and cooperating with the wedge block 42 to drive the upper filter plate 4 and the lower filter plate 5 to move downward, which can further prevent the coal slag from clogging the filter holes.

[0038] Furthermore, a plurality of fixing rods 52 are provided on the periphery of the lower filter plate 5, and a plurality of spiral rotation grooves 9 are opened on the inner wall of the tower body 1. The fixing rods 52 are sleeved in the rotation grooves 9. When the lower filter plate 5 moves downward, the fixing rods 52 move along the rotation grooves 9 to rotate the lower filter plate 5.

[0039] In actual application of this embodiment, when the lower filter plate 5 moves downward, the fixing rod 52 moves along the rotating groove 9, so that the lower filter plate 5 rotates a certain angle while moving downward, so that the filter holes on the upper filter plate 4 and the lower filter plate 5 are misaligned, so that larger coal slag can be effectively prevented from being stuck in the filter holes on the upper filter plate 4, thereby effectively preventing the coal slag from blocking the filter holes on the upper filter plate 4;

[0040] When the lower filter plate 5 rotates, the filter holes on the upper filter plate 4 and the lower filter plate 5 will be misaligned, so that the coal slag originally blocked in the filter holes of the upper filter plate 4 will be squeezed by the edges of the filter holes on the lower filter plate 5, thereby crushing the coal slag and making it fall out of the filter holes, thereby effectively preventing the coal slag from blocking the filter holes on the upper filter plate 4.

[0041] Furthermore, a plurality of circular holes 41 are provided on the upper filter plate 4, and the diameters of the circular holes 41 on the upper filter plates 4 gradually decrease from top to bottom. A plurality of conical holes 51 are provided on the lower filter plate 5, and the diameters of the conical holes 51 on the lower filter plates 5 gradually decrease from top to bottom. The diameter of the conical hole 51 close to one end of the upper filter plate 4 is equal to the diameter of the circular hole 41, and the diameter of the conical hole 51 away from one end of the upper filter plate 4 is greater than the diameter of the circular hole 41.

[0042] In one case of this embodiment, the circular hole 41 and the conical hole 51 are both the filter holes mentioned above.

[0043] In practical application, the present embodiment uses the upper filter plate 4 and the lower filter plate 5 at different heights to filter. Since the filter holes of the upper filter plate 4 and the lower filter plate 5 at different heights have different sizes, the coal slag of different sizes can be classified, thereby improving the separation effect.

[0044] The inner ring of the top part of the conical hole 51 is in a sharp state, so that when the lower filter plate 5 rotates, the conical hole 51 can easily break the coal slag blocked in the round hole 41, avoiding the lower filter plate 5 from getting stuck during the rotation process and preventing the cleaning brush 6 from being blocked by the wedge block 42 and unable to rotate normally.

[0045] like Figure 1-Figure 5 As shown, the tops of the upper filter plate 4 and the lower filter plate 5 are both inclined downward from the middle.

[0046] In actual application of this embodiment, the coal slag separated from the upper filter plate 4 will slowly move along the inclined surface of the upper filter plate 4 to the edge of the upper filter plate 4, thereby preventing these coal slags from affecting the smaller-sized coal slags passing through the filter holes on the upper filter plate 4.

[0047] Furthermore, a plurality of discharge ports 7 are provided on the tower body 1 , and sealing members 8 are installed at the discharge ports 7 .

[0048] Furthermore, the discharge port 7 includes a discharge channel 71, which is located on one side of the inner cavity of the tower body 1 and is flush with the top edge of the upper filter plate 4. The bottom of the discharge channel 71 is inclined downward toward the side away from the tower body 1. The seal 8 includes a sealing plate 81. A movable groove 72 is opened in the tower body 1. The sealing plate 81 is movably inserted in the movable groove 72, and the sealing plate 81 blocks the discharge channel 71.

[0049] Furthermore, a plurality of movable grooves 73 are provided on the inner wall of the tower body 1, and the movable grooves 73 are connected to the movable grooves 72. A connecting block 83 is movably inserted in the movable grooves 73. One side of the connecting block 83 is fixedly connected to the sealing plate 81, and the other side of the connecting block 83 is fixedly connected to a guide plate 82. The guide plate 82 is located in the tower body 1, and a guide groove 821 in an inclined state is provided on the surface of the guide plate 82. A connecting rod 611 is connected to the cleaning brush 6, and an inclined block 62 is fixed to the connecting rod 611. During the rotation of the cleaning brush 6, the inclined block 62 is inserted into the guide groove 821 and moves along the guide groove 821.

[0050] It should be noted that the coal slag separated from the upper filter plate 4 needs to be cleaned regularly to avoid excessive accumulation of coal slag that reduces the separation effect of the upper filter plate 4 .

[0051] When this embodiment is actually used, during the rotation of the cleaning brush 6, the inclined block 62 slowly approaches the guide plate 82, and the inclined block 62 enters the guide groove 821. Since the inclined block 62 rotates with the cleaning brush 6, the inclined block 62 is always in a horizontal plane, and since the inclined block 62 moves along the guide groove 821, the guide plate 82 slowly moves upward. During the upward movement, the guide plate 82 drives the sealing plate 81 to move upward, thereby opening the discharge channel 71. At this time, the coal slag separated by the upper filter plate 4 will be discharged through the discharge channel 71. When the inclined block 62 passes over the guide groove 821, the sealing plate 81 and the guide plate 82 move downward due to their own weight, and the sealing plate 81 blocks the discharge channel 71. Such intermittent discharge of coal slag can effectively avoid excessive accumulation of coal slag, which reduces the separation effect of the upper filter plate 4.

[0052] like Figure 1 As shown, a chassis 11 is provided at the bottom of the tower body 1, and both sides of the top of the chassis 11 are in an inclined state. A sewage pipe 12 and a drainage pipe 13 are respectively connected to the tower body 1, and the sewage pipe 12 and the drainage pipe 13 are respectively located at the inclined parts on both sides of the top of the chassis 11 and connected. A water filter plate 15 is provided on the top of the chassis 11, and a sludge chamber 16 and a water storage chamber 17 are formed between the two sides of the water filter plate 15 and the chassis 11 and the tower body 1, respectively. An inclined inclined plate 14 is provided between the top of the water filter plate 15 and the inner wall of the tower body 1, and the inclined direction of the inclined plate 14 is toward the sludge chamber 16.

[0053] It should be noted that the wastewater generated by the coal chemical industry contains not only coal slag but also sludge. The sludge will not be separated by the upper filter plate 4 and the lower filter plate 5, but will continue to flow with the wastewater.

[0054] In actual application of this embodiment, most of the wastewater after multi-stage separation contains only sludge. At this time, the wastewater enters the sludge chamber 16 through the guidance of the inclined plate 14, and enters the water storage chamber 17 through the filtration of the water filter plate 15, while the sludge remains in the sludge chamber 16, so that the water and sludge in the wastewater are separated, and the separated sludge is discharged from the sewage pipe 12, and the water is discharged through the drainage pipe 13. In this way, not only the coal slag in the wastewater can be separated, but also the sludge in the wastewater can be separated, thereby improving the separation effect.

[0055] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
