Technical Field

[0001] The present invention belongs to the field related to sewage treatment technology, and more specifically to a sewage drying and sludge discharge device for a coal chemical production line. Background Art

[0002] Sewage drying and sludge discharge is an important part of the sewage treatment process. It involves reducing the moisture content of the treated sludge through drying technology to facilitate subsequent transportation, storage and utilization or further treatment. Sewage drying, also known as sludge dehydration, refers to the process of removing most of the water content from the sludge through filtration or evaporation. After the sludge is concentrated, the moisture content of the sludge is further reduced by physical methods.

[0003] The patent document recorded in the prior art CN117088589A discloses a sludge drying pretreatment device and method, which belongs to the technical field of sludge treatment. The sludge drying pretreatment device includes a separation structure, a first sedimentation zone, a second sedimentation zone and a sludge discharge assembly. The separation structure includes a sewage separation cylinder, a sludge separation cylinder, a conveying member and a driving member. A sludge inlet is provided at one end of the sewage separation cylinder, and the other end is connected to the interior of the sludge separation cylinder; the conveying member is arranged between the sewage separation cylinder and the interior of the sludge separation cylinder; the feed end of the first sedimentation zone corresponds to the sewage discharge end of the sewage separation cylinder, and a drain outlet and a sludge outlet are respectively provided on the upper and lower sides of the first sedimentation zone; the feed end of the second sedimentation zone corresponds to the sewage discharge end of the sludge separation cylinder.

[0004] The above-mentioned equipment has certain deficiencies when performing sewage drying and sludge discharge operations. Sedimentation treatment is required during sewage drying operations to separate water from sludge by sedimentation, while the above-mentioned device uses natural sedimentation to perform sewage sedimentation and separation operations, which increases the time required for sewage sedimentation and reduces sewage treatment efficiency; secondly, the above-mentioned device has a single functionality. When performing sludge filter pressing operations, it cannot be adjusted arbitrarily according to the sludge conveying volume, causing the water content in the sludge to exceed the standard and not having a filter pressing condition structure. Secondly, in the subsequent drying process, the block sludge will increase the difficulty of drying, making it impossible for heat to penetrate evenly into the sludge; at the same time, during the sludge conveying process of the above-mentioned device, some sludge is likely to remain on the surface of the conveyor belt, and it does not have a synchronous cleaning structure, which reduces the stability of the equipment during operation. Summary of the invention

[0005] The purpose of the present invention is to provide a sewage drying and sludge discharge device for a coal chemical production line, which can solve the existing problems.

[0006] The problem to be solved by the present invention is:

[0007] 1. Sedimentation treatment is required during the sewage drying operation, and the water body and sludge are separated by sedimentation. However, the above device uses natural sedimentation method to carry out sewage sedimentation and separation operation, which increases the time required for sewage sedimentation and reduces the sewage treatment efficiency;

[0008] 2. Secondly, the above-mentioned device has a single function. When performing sludge filter pressing operation, it cannot be adjusted arbitrarily according to the sludge delivery volume, so that the water content in the sludge exceeds the standard and does not have the filter pressing condition structure. Secondly, in the subsequent drying process, the block sludge will increase its drying difficulty, making it impossible for heat to evenly penetrate into the sludge;

[0009] 3. At the same time, when the above device is conveying sludge, part of the sludge is likely to remain on the surface of the conveyor belt, and there is no synchronous cleaning structure, which reduces the stability of the equipment during operation.

[0010] The purpose of the present invention can be achieved through the following technical solutions:

[0011] The slurry collecting device of claim 1, wherein the slurry collecting device is mounted on a bottom of the slurry collecting basin, and the slurry collecting basin is located on a bottom of the slurry collecting basin.

[0012] As a further technical solution of the present invention, a filter is fixedly installed on the outer surface of the filtrate frame, and the overall structure of the pressing frame is a rectangular frame. A V-shaped groove is provided at the lower part of the sedimentation tank. During the sewage drying operation, the sewage needs to be sedimented in advance so that the sewage is layered up and down, the sludge is placed at the bottom of the tank, and most of the water in the sewage is removed. The traditional sedimentation method is time-consuming. By using the setting of the settler, the filtrate frame can be used in conjunction with the filter to quickly complete the sedimentation of the sludge in the sewage by a lifting method. During operation, the pressing frame is driven by a hydraulic rod so that the pressing frame drives the filtrate frame to move downward. The setting of the pressing frame makes the force on the filtrate frame more uniform. During the descent of the filtrate frame, the filter is driven downward so that the water in the sewage passes through the filter, so that the sludge is retained at the bottom of the filter, and it is placed in the V-shaped groove of the sedimentation tank in conjunction with the movement of the filter.

[0013] As a further technical solution of the present invention, a feeding auger is provided in the V-shaped groove of the sedimentation tank, a drainage pipe is provided on the outer surface of one end of the sedimentation tank, and a sewage pipe is provided on the outer surface of the other end of the sedimentation tank. When the settler completes the mud-water separation operation, the feeding auger is driven to rotate by an electric motor so that the feeding auger discharges the sludge accumulated in the V-shaped groove, and the sludge is transported from the sewage pipe to between the first conveyor belt and the rolling belt for filter pressing operation.

[0014] As a further technical solution of the present invention, the lifting rod and the rolling belt are movably connected by a lifting frame, and a plurality of driving rollers are arranged between the rolling belt and the lifting frame, and the driving rollers are used to drive the rolling belt to rotate. When the first conveyor belt transports the sludge and moves, the sludge is rolled between the rolling belt and the first conveyor belt in coordination with the rotation of the rolling belt, so that the water passes through the mesh structure of the first conveyor belt and is discharged downward. The setting of the lifting frame can adjust the use height of the rolling belt according to the water content of the sludge, and plays a role in regulating the distance between the rolling belt and the first conveyor belt. The setting of the cleaning roller can clean the mesh structure on the surface of the first conveyor belt when the first conveyor belt moves, so that the first conveyor belt always maintains a good filtration effect.

[0015] As a further technical solution of the present invention, a drainage pan used in conjunction with the first conveyor belt is fixedly installed on one side of the fixed base, and an exhaust hood used in conjunction with the dryer is provided on the outer surface of one end of the fixed base. The drainage pan can collect water generated after the first conveyor belt is filtered and discharged. Secondly, when the dryer is drying the sludge, the gas generated is discharged to the outside through the exhaust hood.

[0016] As a further technical solution of the present invention, a discharge hopper is provided at the front end of the fixed base, and the discharge hopper is located at the discharge end of the second conveyor belt. A plurality of positioning rollers are movably installed on the inner side of the second conveyor belt. The second conveyor belt drives the sludge to move, and the sludge is dried by a dryer to remove residual moisture in the sludge, and the dried sludge is discharged outwardly by the discharge hopper.

[0017] As a further technical solution of the present invention, the crushing roller and the fixed base are connected and fixed by a fixed frame, and the outer surface of the crushing roller is provided with a plurality of rolling cutting rings. When the second conveyor belt performs sludge conveying operation, the crushing roller can be used to crush the sludge after rolling and dehydration, thereby improving its subsequent drying effect.

[0018] As a further technical solution of the present invention, slitting heads are provided between several groups of rolling cutting rings, and several groups of rolling cutting rings are arranged side by side. The slitting heads are distributed in a ring shape. When the crushing roller rotates, the crushing roller drives several groups of rolling cutting rings and the slitting heads to rotate synchronously. The rolling cutting rings and the slitting heads are used to crush the sludge and cut the sludge into small pieces so that the dryer can quickly dry it.

[0019] As a further technical solution of the present invention, the crushing roller and the fixed frame are movably connected via a rotating rod, and one end of the rotating rod is driven by a motor.

[0020] As a further technical solution of the present invention, a material receiving box is provided on the lower surface of the second conveyor belt, and a support plate and an elastic scraper are obliquely provided on the upper end of the material receiving box. The elastic scraper is movably installed on the inner side of the support plate, and the support plate and the elastic scraper are elastically connected by a spring. By utilizing the arrangement of the support plate and the elastic scraper, the surface of the second conveyor belt can be scraped and cleaned when the second conveyor belt moves, thereby removing residual sludge on the surface of the second conveyor belt.

[0021] Beneficial effects of the present invention:

[0022] 1. By setting up a settler, when the sewage drying and sludge discharge device is used in the coal chemical production line, it replaces the traditional natural sedimentation method for sewage treatment, shortens the time required for sewage sedimentation operation, quickly separates the water body and sludge, and improves its treatment efficiency;

[0023] During operation, during the sewage drying treatment operation, it is necessary to perform sedimentation treatment on the sewage in advance, so that the sewage is layered up and down, the sludge is placed at the bottom of the pool, and most of the water in the sewage is removed. The traditional sedimentation method is time-consuming. By using the setting of the settler, the filtrate frame can be used in conjunction with the filter screen, and the sedimentation of the sludge in the sewage can be quickly completed by the lifting method. During operation, the sewage is introduced into the sedimentation tank through the water inlet pipe, and flocculants are added to the sewage to accelerate its precipitation reaction. The pressure frame is driven by the hydraulic rod so that the pressure frame drives the filtrate frame to move down. The setting of the pressure frame makes the force of the filtrate frame more uniform. The filter screen is driven to move down during the descent of the filtrate frame, so that the water in the sewage passes through the filter screen, so that the sludge is retained at the bottom of the filter screen, and it is placed in the V-shaped groove of the sedimentation tank in conjunction with the movement of the filter screen. When the settler completes the mud-water separation operation, the feed auger is driven to rotate by the motor so that the feed auger discharges the sludge accumulated in the V-shaped groove, so that the sludge is transported from the sewage discharge pipe to between the first conveyor belt and the rolling belt for filter pressing.

[0024] 2. By setting the rolling belt and the crushing roller, when the sewage drying and sludge discharge device for the coal chemical production line is used, the rolling effect can be adjusted arbitrarily according to the amount of sludge, the water content in the sludge can be reduced, and the sludge crushing process can be completed synchronously, thereby improving the subsequent drying and dehydration effect;

[0025] During use, when the first conveyor belt is conveying the sludge, the sludge is rolled between the rolling belt and the first conveyor belt in coordination with the rotation of the rolling belt, so that the water passes through the mesh structure of the first conveyor belt and is discharged downward. The setting of the lifting frame can adjust the use height of the rolling belt according to the water content of the sludge. The lifting frame is driven by the lifting rod so that the lifting frame drives the rolling belt to move up and down, thereby adjusting the distance between the rolling belt and the first conveyor belt. The setting of the cleaning roller can clean the mesh structure on the surface of the first conveyor belt when the first conveyor belt moves, so that the first conveyor belt always maintains a good filtration effect. Secondly, when the crushing roller rotates, the crushing roller drives several groups of rolling cutting rings and slitting heads to rotate synchronously, and uses the rolling cutting rings and slitting heads to crush the sludge and cut the sludge into small pieces, so that the dryer can dry it quickly and improve its drying and dehydration effect.

[0026] 3. By setting a cleaning roller and an elastic scraper, when the sewage drying and sludge discharge device for the coal chemical production line is used, it has a double cleaning structure, which improves the operation stability of the equipment and avoids sludge blocking the operation of the equipment;

[0027] During operation, the cleaning roller is installed at the lower position of one end of the first conveyor belt. When the surface of the cleaning roller is in a brush-like structure, when the first conveyor belt is running, the brush structure on the surface of the cleaning roller passes through the mesh structure of the first conveyor belt to clean the sludge blocking the first conveyor belt, and at the same time, the sludge discharged from the first conveyor belt is discharged downward to complete the cleaning operation of the first conveyor belt. Secondly, the support plate and the elastic scraper are elastically connected by a spring, so that the elastic scraper is in elastic contact with the surface of the second conveyor belt. By utilizing the arrangement of the support plate and the elastic scraper, the surface of the second conveyor belt can be scraped and cleaned when the second conveyor belt moves, so as to remove residual sludge on the surface of the second conveyor belt.

DETAILED DESCRIPTION

[0036] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0037] like Figure 1 As shown, a sewage drying and sludge discharge device for a coal chemical production line comprises a fixed base 3 and a sedimentation tank 8, wherein the sedimentation tank 8 is fixedly mounted on the outer surface of the upper end of the fixed base 3, and a lifting rod 6 is provided on the upper end of the fixed base 3, and a settler 7 is movably mounted on the inner side of the upper end of the sedimentation tank 8; the settler 7 comprises a filtrate frame 15 and a pressing frame 16, wherein the filtrate frame 15 is fixedly mounted on the lower end of the pressing frame 16, and the upper end of the pressing frame 16 and the sedimentation tank 8 are driven by a hydraulic rod 17; a rolling belt 11 is movably mounted on the lower part of the lifting rod 6, and a first conveyor belt 9 is movably mounted below the rolling belt 11, and the first conveyor belt 9 is located on the inner side of the fixed base 3, and a cleaning drum 12 is provided at one end of the first conveyor belt 9, and the surface of the first conveyor belt 9 is a mesh structure; a dryer 2 is fixedly mounted on the inner side of the fixed base 3, and a second conveyor belt 19 is provided below the dryer 2, and a crushing roller 21 is movably mounted on the upper surface of the second conveyor belt 19.

[0038] To solve the problem of slow sewage sedimentation, such as Figure 3As shown, a filter screen 29 is fixedly installed on the outer surface of the filtrate frame 15, and the whole of the pressing frame 16 is a rectangular frame structure. A V-shaped groove is provided at the lower part of the sedimentation tank 8. During the sewage drying operation, the sewage needs to be sedimented in advance so that the sewage is layered up and down, the sludge is placed at the bottom of the tank, and most of the water in the sewage is removed. The traditional sedimentation method is time-consuming. By using the setting of the settler 7, the filtrate frame 15 can be used in conjunction with the filter screen 29 to quickly complete the sedimentation of the sludge in the sewage by a lifting method. During operation, the hydraulic rod 17 is used to drive the pressing frame 16, so that the pressing frame 16 drives the filtrate frame 15 to move downward. The setting of the pressing frame 16 makes the force on the filtrate frame 15 more uniform. During the descent of the filtrate frame 15, the filter screen 29 is driven downward, so that the water in the sewage passes through the filter screen 29, so that the sludge is retained at the bottom of the filter screen 29, and it is placed in the V-shaped groove of the sedimentation tank 8 in conjunction with the movement of the filter screen 29.

[0039] like Figure 3 As shown, a feed auger 14 is provided in the V-shaped groove of the sedimentation tank 8, a drainage pipe is provided on the outer surface of one end of the sedimentation tank 8, and a sewage pipe is provided on the outer surface of the other end of the sedimentation tank 8. When the settler 7 completes the mud-water separation operation, the feed auger 14 is driven to rotate by the motor so that the feed auger 14 discharges the sludge accumulated in the V-shaped groove, and the sludge is transported from the sewage pipe to between the first conveyor belt 9 and the rolling belt 11 for filter pressing operation.

[0040] To solve the problem of high residual water rate after sludge rolling, Figure 2 As shown, the lifting rod 6 and the rolling belt 11 are movably connected through the lifting frame 10, and a plurality of driving rollers 13 are arranged between the rolling belt 11 and the lifting frame 10. The driving rollers 13 are used to drive the rolling belt 11 to rotate. When the first conveyor belt 9 transports the sludge and moves, the rolling belt 11 rotates to complete the rolling operation of the sludge between the rolling belt 11 and the first conveyor belt 9, so that the water passes through the mesh structure of the first conveyor belt 9 and is discharged downward. The setting of the lifting frame 10 can adjust the use height of the rolling belt 11 according to the water content of the sludge, and play a role in adjusting the distance between the rolling belt 11 and the first conveyor belt 9. The setting of the cleaning roller 12 can clean the mesh structure on the surface of the first conveyor belt 9 when the first conveyor belt 9 moves, so that the first conveyor belt 9 always maintains a good filtration effect.

[0041] A drainage pan 4 for use with the first conveyor belt 9 is fixedly installed on one side of the fixed base 3. An exhaust hood 5 for use with the dryer 2 is provided on the outer surface of one end of the fixed base 3. The drainage pan 4 can collect the water generated after the first conveyor belt 9 is filtered and discharged. Secondly, when the dryer 2 is drying the sludge, the gas generated is discharged to the outside through the exhaust hood 5.

[0042] like Figure 4As shown, a discharge hopper 1 is provided at the front end of the fixed base 3, and the discharge hopper 1 is located at the discharge end of the second conveyor belt 19. A plurality of positioning rollers 20 are movably installed on the inner side of the second conveyor belt 19. The second conveyor belt 19 drives the sludge to move, and the dryer 2 is used to dry the sludge to remove residual moisture in the sludge, and the dried sludge is discharged outwardly by the discharge hopper 1.

[0043] In order to solve the problem of poor drying effect of bulk sludge, Figure 5 As shown, the crushing roller 21 and the fixed base 3 are connected and fixed by a fixed frame 24. The outer surface of the crushing roller 21 is provided with a plurality of rolling cutting rings 23. When the second conveyor belt 19 performs sludge conveying operation, the crushing roller 21 can be used to crush the sludge after rolling and dehydration, thereby improving its subsequent drying effect.

[0044] like Figure 5 As shown, slitting heads 22 are provided between several groups of rolling cutting rings 23, and several groups of rolling cutting rings 23 are arranged side by side. The slitting heads 22 are distributed in a ring shape. When the crushing roller 21 rotates, the crushing roller 21 drives several groups of rolling cutting rings 23 and the slitting heads 22 to rotate synchronously. The rolling cutting rings 23 and the slitting heads 22 are used to crush the sludge and cut the sludge into small pieces, so that the dryer 2 can dry it quickly.

[0045] The crushing roller 21 and the fixed frame 24 are movably connected via a rotating rod 25 , and one end of the rotating rod 25 is driven by a motor 26 .

[0046] In order to solve the problem of residual sludge when the equipment is transporting sludge, Figure 6 As shown, a material receiving box 18 is provided on the lower surface of the second conveyor belt 19, and a support plate 27 and an elastic scraper 28 are obliquely provided on the upper end of the material receiving box 18. The elastic scraper 28 is movably installed on the inner side of the support plate 27. The support plate 27 and the elastic scraper 28 are elastically connected by a spring. By using the arrangement of the support plate 27 and the elastic scraper 28, the surface of the second conveyor belt 19 can be scraped and cleaned when the second conveyor belt 19 moves, and residual sludge on the surface of the second conveyor belt 19 can be removed;

[0047] When in use, the sewage drying operation requires sedimentation treatment, and the water body and sludge are separated by sedimentation. However, the above device uses natural sedimentation to carry out sewage sedimentation and separation operations, which increases the time required for sewage sedimentation and reduces the sewage treatment efficiency.

[0048] To this end, by setting the settler 7, when the sewage drying and sludge discharge device is used in the coal chemical production line, the sewage treatment is carried out instead of the traditional natural sedimentation method, the time required for the sewage sedimentation operation is shortened, the water body and the sludge are quickly separated, and the treatment efficiency is improved;

[0049] During operation, during the sewage drying treatment operation, it is necessary to perform sedimentation treatment on the sewage in advance, so that the sewage is layered up and down, the sludge is placed at the bottom of the pool, and most of the water in the sewage is removed. The traditional sedimentation method takes a long time. By using the setting of the settler 7, the filtrate frame 15 can be used in conjunction with the filter screen 29 to quickly complete the sedimentation of the sludge in the sewage by using the lifting method. During operation, the sewage is introduced into the sedimentation tank 8 through the water inlet pipe, and a flocculant is added to the sewage to accelerate its precipitation reaction. The hydraulic rod 17 is used to drive the pressing frame 16, so that the pressing frame 16 drives the filtrate frame 15 moves downward, and the setting of the pressing frame 16 makes the force on the filtrate frame 15 more uniform. During the descent of the filtrate frame 15, the filter screen 29 is driven to move downward, so that the water in the sewage passes through the filter screen 29, so that the sludge is retained in the lower part of the filter screen 29, and the filter screen 29 is placed in the V-shaped groove of the sedimentation tank 8 in coordination with the movement of the filter screen 29. When the sedimentator 7 completes the mud-water separation operation, the feed auger 14 is driven by the motor to rotate, so that the feed auger 14 discharges the sludge accumulated in the V-shaped groove, so that the sludge is transported from the sewage discharge pipe to between the first conveyor belt 9 and the rolling belt 11 for filter pressing operation;

[0050] Secondly, the above device has a single function. When performing sludge filter pressing operation, it cannot be adjusted arbitrarily according to the sludge delivery volume, so that the water content in the sludge exceeds the standard and does not have the filter pressing condition structure. Secondly, in the subsequent drying process, the block sludge will increase its drying difficulty, making it impossible for heat to evenly penetrate into the sludge;

[0051] To this end, by setting the rolling belt 11 and the crushing roller 21, when the sewage drying and sludge discharge device for the coal chemical production line is used, the rolling effect can be adjusted arbitrarily according to the amount of sludge, the water content in the sludge can be reduced, and the sludge crushing process can be completed synchronously, thereby improving the subsequent drying and dehydration effect;

[0052] During use, when the first conveyor belt 9 is conveying the sludge, the sludge is rolled between the rolling belt 11 and the first conveyor belt 9 in coordination with the rotation of the rolling belt 11, so that the water passes through the mesh structure of the first conveyor belt 9 and is discharged downward. The setting of the lifting frame 10 can adjust the use height of the rolling belt 11 according to the water content of the sludge. The lifting frame 10 is driven by the lifting rod 6, so that the lifting frame 10 drives the rolling belt 11 to move up and down, and plays a role in adjusting the distance between the rolling belt 11 and the first conveyor belt 9. The setting of the cleaning roller 12 can clean the mesh structure on the surface of the first conveyor belt 9 when the first conveyor belt 9 moves, so that the first conveyor belt 9 always maintains a good filtration effect. Secondly, when the crushing roller 21 rotates, the crushing roller 21 drives several groups of rolling rings 23 and slitting heads 22 to rotate synchronously, and the rolling rings 23 and the slitting heads 22 are used to crush the sludge and cut the sludge into small pieces, so that the dryer 2 can dry it quickly and improve its drying and dehydration effect.

[0053] At the same time, during the sludge conveying process of the above device, part of the sludge is likely to remain on the surface of the conveyor belt, and there is no synchronous cleaning structure, which reduces the stability of the equipment during operation;

[0054] To this end, by providing a cleaning drum 12 and an elastic scraper 28, when the sewage drying and sludge discharge device for the coal chemical production line is used, it has a double cleaning structure, thereby improving the operation stability of the equipment and preventing sludge from blocking the operation of the equipment;

[0055] During operation, the cleaning roller 12 is installed at the lower position of one end of the first conveyor belt 9. When the surface of the cleaning roller 12 is in a brush-like structure, when the first conveyor belt 9 is running, the brush structure on the surface of the cleaning roller 12 passes through the mesh structure of the first conveyor belt 9 to clean the sludge blocked on the first conveyor belt 9, and at the same time, the sludge discharged from the first conveyor belt 9 is discharged downward to complete the cleaning operation of the first conveyor belt 9. Secondly, the support plate 27 and the elastic scraper 28 are elastically connected by a spring, so that the elastic scraper 28 is in elastic contact with the surface of the second conveyor belt 19. By utilizing the arrangement of the support plate 27 and the elastic scraper 28, the surface of the second conveyor belt 19 can be scraped and cleaned when the second conveyor belt 19 moves, thereby removing residual sludge on the surface of the second conveyor belt 19.

[0056] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
