Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater removal device for coal coking wastewater treatment. Background Technology

[0002] Coal coking, also known as high-temperature carbonization of coal, is a coal conversion process that uses coal as raw material and heats it to about 950°C in the absence of air to produce coke through high-temperature carbonization. At the same time, it obtains coal gas, coal tar, and recovers other chemical products. In recent years, the coking industry has undergone tremendous changes, especially in environmental governance, technological progress, and deep processing of chemical products. It has reached a considerable scale. The structural adjustment, technological progress, energy conservation and emission reduction, and equipment level of the coking industry have been greatly improved. A large amount of wastewater is generated during the coal coking process. Because the wastewater contains many impurities, it needs to be filtered.

[0003] However, after prolonged use, impurities and pollutants accumulate on the filter pores, which prevents wastewater from passing through the filter pores quickly and reduces the efficiency of subsequent wastewater treatment. To address this, we propose a wastewater removal device for coal coking wastewater treatment. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a wastewater removal device for coal coking wastewater treatment. First, a long pin is inserted into the insertion hole. Then, coal coking wastewater is introduced through the upper inlet of a five-way pipe and exits through the four outlets at the lower end of the five-way pipe into the wastewater removal cylinder. The wastewater is then removed using the filter holes of the wastewater removal cylinder. Finally, the removed wastewater is discharged through the outlet pipe. After prolonged use, the filter holes of the wastewater removal cylinder may become clogged. At this point, a water washing component is activated to wash the filter holes of the wastewater removal cylinder, improving the subsequent cleaning effect. Then, the first drive component drives the lead screw to rotate. The rotation of the lead screw causes the moving block to move under the sliding action of the limiting column and the connecting bracket. The movement of the moving block causes the connecting bracket and the annular cleaning brush to move. The annular cleaning brush, in contact with the inner wall of the wastewater removal cylinder, reciprocates up and down to further clean the inner wall of the wastewater removal cylinder, thereby further improving the wastewater removal effect and efficiency. Impurities are discharged and collected under the action of the slag discharge component, effectively solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment device for coal coking wastewater, comprising a treatment tank, a wastewater removal cylinder, an annular cleaning brush, a water washing assembly, and a slag discharge assembly;

A water outlet pipe is installed on the outer side of the treatment tank. The water outlet pipe is located between two annular plates.

[0007] Furthermore, the water washing assembly includes water tanks installed on both sides of the upper surface of the treatment tank.

Multiple connecting pipes are evenly installed inside the diversion pipe, with the other end of each connecting pipe located inside the treatment tank. A nozzle is installed at the end of each connecting pipe. A rotating shaft is rotatably installed on the bottom surface of the treatment tank, with its upper end fixedly connected to the lower surface of the impurity removal cylinder. A second drive assembly is installed on the bottom surface of the treatment tank, and the second drive assembly is connected to the rotating shaft. First, the long pin is pulled out of the insertion hole. Then, the second drive assembly drives the rotating shaft to rotate, which in turn drives the impurity removal cylinder to rotate. Simultaneously, the water pump operates, delivering clean water from the water tanks sequentially through the diversion pipe and connecting pipes to the nozzle. Finally, the clean water sprayed from the nozzle washes and cleans the filter holes of the impurity removal cylinder, thereby improving the subsequent cleaning effect.

[0008] Furthermore, the second drive assembly includes a second motor bracket mounted on the bottom of the processing tank, on which a second motor is mounted. The output shaft of the second motor is connected to the lower end of the rotating shaft via a second coupling, and the input end of the second motor is electrically connected to the output end of an external controller. The second motor is controlled by the external controller, and its operation drives the rotating shaft to rotate, thereby electrically completing the rotation of the rotating shaft.

[0009] Furthermore, the slag discharge assembly includes slag discharge ports on both sides of the lower surface of the impurity removal cylinder.

The locking block and the slot can also be detachably connected by screws, pins, etc.

A first motor is mounted on the first motor bracket, and the output shaft of the first motor is connected to the upper end of the lead screw via a first coupling. The input end of the first motor is electrically connected to the output end of an external controller. The external controller controls the operation of the first motor, which drives the lead screw to rotate, thereby electrically completing the forward or reverse rotation of the lead screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In the use of this impurity removal device for coal coking wastewater treatment, the long pin is first inserted into the insertion hole, and then the coal coking wastewater is introduced through the upper inlet of the five-way pipe and discharged into the impurity removal cylinder through the four outlets at the lower end of the five-way pipe. Then, the impurity removal cylinder is used to remove impurities from the coal coking wastewater. Finally, the impurity-removed wastewater is discharged through the outlet pipe. After long-term use, the filter holes of the impurity removal cylinder may become clogged. At this time, the water washing component is activated to wash the filter holes of the impurity removal cylinder to improve the subsequent cleaning effect. Then, the first drive component drives the lead screw to rotate. The rotation of the lead screw drives the moving block to move under the sliding action of the limit column and the connecting bracket. The movement of the moving block drives the connecting bracket and the annular cleaning brush to move. Thus, the annular cleaning brush, which is in contact with the inner wall of the impurity removal cylinder, moves up and down to further clean the inner wall of the impurity removal cylinder, thereby further improving the impurity removal effect and efficiency of the impurity removal cylinder. Among them, impurities are discharged and collected under the action of the slag discharge component. Attached Figure Description

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.

[0016] Please see Figure 1-2 This embodiment provides a technical solution: a wastewater treatment device for coal coking wastewater, including a treatment tank 1, a wastewater removal cylinder 15, an annular cleaning brush 16, a water washing assembly, and a slag discharge assembly;

[0017] Multiple support legs 4 are evenly installed on the lower surface of the treatment tank 1. A five-way pipe 6 is installed in the middle of the upper surface of the treatment tank 1. Multiple filter holes 14 are evenly opened on the outer surface of the impurity removal cylinder 15.

The outer ends of the annular plates 13 are slidably and rotatably connected to the corresponding annular grooves. Multiple insertion holes are evenly opened on the upper surface of the treatment tank 1. The insertion holes pass through two annular plates 13 in sequence. Long pins 2 are detachably inserted into the insertion holes. The four lower ends of the five-way pipe 6 pass through the upper surface of the treatment tank 1 and communicate with the impurity removal cylinder 15. A slag discharge assembly is provided on the inner bottom surface of the impurity removal cylinder 15. The lower end of a screw 12 is rotatably installed on the inner bottom surface of the impurity removal cylinder 15. The upper end of the screw 12 passes through the upper surface of the impurity removal cylinder 15 in sequence. The upper surface of the treatment tank 1 is connected to the upper surface of the impurity removal cylinder 15 and the upper surface of the treatment tank 1. The upper end of the lead screw 12 is rotatably connected to the upper surface of the impurity removal cylinder 15 and the upper surface of the treatment tank 1.

[0018] In use, first insert the long pin 2 into the socket, then introduce the coal coking wastewater through the upper inlet of the five-way pipe 6, and exit through the four outlets at the lower end of the five-way pipe 6 into the impurity removal cylinder 15. Next, use the filter holes of the impurity removal cylinder 15 to remove impurities from the coal coking wastewater. Finally, discharge the removed wastewater through the outlet pipe. After prolonged use, the filter holes of the impurity removal cylinder 15 may become clogged. At this time, activate the water washing assembly to wash the filter holes of the impurity removal cylinder 15 to improve the subsequent cleaning effect. The first drive assembly drives the lead screw 12 to rotate. The rotation of the lead screw 12 causes the moving block 21 to move under the sliding action of the limit post 11 and the connecting bracket 20. The movement of the moving block 21 causes the connecting bracket 20 and the annular cleaning brush 16 to move.

The upper end of the rotating shaft 18 is fixedly connected to the lower surface of the impurity removal cylinder 15. A second drive assembly is installed on the bottom surface of the treatment tank 1, and the second drive assembly is connected to the rotating shaft 18. First, the long pin 2 is pulled out of the insertion hole. Then, the second drive assembly drives the rotating shaft 18 to rotate. The rotation of the rotating shaft 18 drives the impurity removal cylinder 15 to rotate. At the same time, the water pump works to send the cleaning water from the water tank 26 through the diversion pipe 9 and the connecting pipe 10 to the nozzle 22. Finally, the cleaning water sprayed by the nozzle 22 washes and cleans the filter holes of the impurity removal cylinder 15 to improve the subsequent cleaning effect.

The input end of the second motor 23 is electrically connected to the output end of an external controller. The second motor 23 is controlled by the external controller to rotate, thereby driving the rotating shaft 18 to rotate electrically.

[0021] The slag discharge assembly includes slag discharge ports 17 on both sides of the lower surface of the impurity removal cylinder 15. A slot is provided on the outer side of each slag discharge port 17. A slag discharge plate 24 is rotatably mounted on the inner wall of the slag discharge port 17 near the lead screw 12 via a first pin. A locking block 25 is mounted on the outer side of the slag discharge plate 24, and the locking block 25 and the slot are snapped together. A slag outlet is provided on the lower outer side of the processing tank 1, and a slag outlet plate 3 is rotatably mounted on the slag outlet via a second pin.

The locking block 25 and the slot can also be detachably connected by screws, pins, etc.

[0022] The first drive assembly includes a first motor bracket 5 mounted on the middle of the upper surface of the processing tank 1. A first motor 7 is mounted on the first motor bracket 5. The output shaft of the first motor 7 is connected to the upper end of the lead screw 12 via a first coupling. The input end of the first motor 7 is electrically connected to the output end of an external controller. The first motor 7 is controlled by the external controller to drive the lead screw 12 to rotate, thereby electrically completing the forward or reverse rotation of the lead screw 12.

[0023] The working principle of the impurity removal device for coal coking wastewater treatment provided by this utility model is as follows: In use, first insert the long pin 2 into the insertion hole, then pass the coal coking wastewater through the upper inlet of the five-way pipe 6, and out through the four outlets at the lower end of the five-way pipe 6 into the impurity removal cylinder 15. Then, the impurity removal cylinder 15 is used to remove impurities from the coal coking wastewater. Finally, the removed wastewater is discharged through the outlet pipe. After prolonged use, the filter holes of the impurity removal cylinder 15 may become clogged. At this time, the water washing assembly is activated to wash the filter holes of the impurity removal cylinder 15. To improve the subsequent cleaning effect, the first drive component drives the lead screw 12 to rotate. The rotation of the lead screw 12 drives the moving block 21 to move under the sliding action of the limit post 11 and the connecting bracket 20. The movement of the moving block 21 drives the connecting bracket 20 and the annular cleaning brush 16 to move. Thus, the annular cleaning brush 16, which is in contact with the inner wall of the impurity removal cylinder 15, moves up and down to further clean the inner wall of the impurity removal cylinder 15, thereby further improving the impurity removal effect and efficiency of the impurity removal cylinder 15. Among them, the impurities are discharged and collected under the action of the slag discharge component. First, the long pin 2 is pulled out of the insertion hole. Then, the second drive component drives the rotating shaft 18 to rotate. The rotation of the rotating shaft 18 drives the impurity removal cylinder 15 to rotate. At the same time, the water pump works to send the cleaning water in the water tank 26 to the nozzle 22 through the diversion pipe 9 and the connecting pipe 10. Finally, the cleaning water sprayed by the nozzle 22 washes and cleans the filter holes of the impurity removal cylinder 15, thereby improving the subsequent cleaning effect. The second motor 23 is controlled by an external controller, which drives the rotating shaft 18 to rotate, thus electrically completing the rotation of the rotating shaft 18. The slag outlet 17 can be opened or closed by the latching block 25 of the slag plate 24 and the latching groove of the slag outlet 17, so as to send impurities to the bottom of the processing tank 1, and then discharge the impurities to the outside for collection through the slag outlet. The latching block 25 and the latching groove can also be detachably connected by mounting screws, pins, etc. The first motor 7 is controlled by an external controller, which drives the lead screw 12 to rotate, thus electrically completing the forward or reverse rotation of the lead screw 12.

[0024] It is worth noting that in this embodiment, the core chip of the external controller is an STC microcontroller, specifically the STC15W204S.
