Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and more specifically, to a coal washing wastewater treatment device that facilitates the removal of impurities. Background Technology

[0002] In the process of coal washing wastewater treatment, the coal washing wastewater treatment device is the core equipment for achieving water purification and coal resource recovery. The cleaning effect of the coal sludge at the bottom conical sludge outlet and the stability of the inclined tube structure are directly related to the treatment efficiency, resource recovery quality and equipment operation safety. Especially in the treatment scenario of high viscosity coal washing wastewater, the thoroughness of cleaning at the conical sludge outlet, the structural strength of the inclined tube and the separation effect of coal sludge and clean water are particularly important. However, existing coal washing wastewater treatment devices face many problems that need to be solved in practical applications.

[0003] Existing coal washing wastewater treatment devices often use a single-angle fixed inner wall design for the bottom conical sludge outlet. Due to its high viscosity, coal sludge easily accumulates and clumps on the conical surface folds and the edge of the outlet. There is a lack of a targeted rotary scraping and linkage cleaning mechanism. After treatment, the residual coal sludge not only blocks the sludge outlet channel, but also increases the difficulty of subsequent cleaning due to repeated drying and hardening. Long-term operation leads to a sharp drop in the sludge discharge efficiency of the device, which cannot meet the needs of continuous and efficient production, and affects the efficiency of water resource recycling and coal resource recovery rate. To solve the above problems, there is an urgent need for a coal washing wastewater treatment device with a deep cleaning function of the conical sludge outlet that is easy to clean impurities.

[0009] As a further description of the above technical solution: a secondary scraper is fixedly provided on the top of the fixed block, a second slider is fixedly provided at the bottom of the secondary scraper, and a slide rail is provided at the bottom of the second slider that is fixedly connected to the column scraper.

[0010] As a further description of the above technical solution: a plurality of heat dissipation holes are fixedly provided on one side of the motor mounting bracket, and two sedimentation tanks fixedly connected to the housing are provided at the bottom of the heat dissipation holes. A sludge discharge pipe is fixedly provided on one side of the bottom of the sedimentation tank, and a sludge discharge pump is fixedly provided on one side of the sludge discharge pipe.

[0011] As a further description of the above technical solution: a left support leg is fixedly provided at the bottom of the housing, the cross-section of the left support leg is L-shaped, and a right support leg is fixedly connected to the housing on one side of the left support leg, the right support leg being cylindrical.

[0012] As a further description of the above technical solution: a drug outlet pipe is fixedly provided on one side of the dosing tank, a conveying plate is fixedly provided on one side of the reaction tank, and one side of the support frame is fixedly connected to the reaction tank and the other side is fixedly connected to the shell.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Through the motor and crank-connecting rod structure, during the use of the sludge pump, a small amount of sludge will adhere to the inner wall of the sedimentation tank. At this time, the motor on the motor mounting bracket is started. The motor output end rotates to drive the crankshaft inside the support bracket to rotate, which causes the crank fixedly connected to the crankshaft to rotate, driving the connecting rod connected to it to move vertically. Compared with the existing technology, by using the motor to drive the crankshaft, connecting rod and other transmission mechanisms, the main scraper and the auxiliary scraper can move vertically. The speed of the motor can be adjusted, and the movement speed and stroke of the connecting rod can be precisely controlled through the crank-connecting rod structure, so as to flexibly adjust the cleaning force of the scraper. This can not only ensure the effective removal of stubborn sludge, but also avoid damage to the inner wall of the sedimentation tank due to excessive force.

[0015] 2. Through the scraper structure, the horizontal plate moves up and down after the connecting rod moves vertically. After the telescopic rod extends and retracts, it drives the slider one to move horizontally on the slide groove, realizing the horizontal movement of the main scraper and the auxiliary scraper. When sliding downwards, the diameter of the sedimentation tank decreases, and the fixed block will drive the slider two at the bottom of the auxiliary scraper to move and retract on the slide rail under the action of the spring. During the up and down movement, the main scraper and the auxiliary scraper extend and retract within the constraints of the internal structure of the sedimentation tank. Compared with the existing technology, the scraper structure design of this cleaning component can be adjusted to a certain extent according to the shape and size of the sedimentation tank. Through the cooperation of components such as the telescopic rod and the slider, the cleaning range and effect of the scraper are further optimized, which can better ensure the cleanliness of the sedimentation tank.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0028] As attached Figure 1-10 The coal washing wastewater treatment device shown is designed for easy cleaning of impurities. It includes a shell 1, an inlet pipe 2 fixedly installed on one side of the shell 1, an outlet pipe 3 fixedly installed on the other side of the shell 1, a dosing tank 4 fixedly installed inside the shell 1, a reaction tank 5 fixedly installed on one side of the dosing tank 4, both the reaction tank 5 and the dosing tank 4 have an S-shaped cross-section, an inclined tube 6 fixedly installed on one side of the reaction tank 5, an inclined tube fixing block 22 fixedly connected to the shell 1 fixedly installed at the bottom of the inclined tube 6, a coal sludge cleaning component installed at the bottom of the inclined tube fixing block 22, a motor fixing frame 8 fixedly connected to the shell 1 installed on one side of the coal sludge cleaning component, and a sedimentation tank 9 fixedly connected to the shell 1 installed at the bottom of the motor fixing frame 8.

[0029] In some embodiments, according to Figure 4-6 As shown, the coal sludge cleaning assembly includes a motor 10 fixedly connected to a motor mounting bracket 8. A crankshaft 11 is fixedly mounted on the output end of the motor 10. Two cranks 12 are fixedly mounted on one side of the crankshaft 11. A connecting rod 13 is sleeved between the cranks 12. The speed of the motor 10 is adjustable, and the moving speed and stroke of the connecting rod 13 are precisely controlled through the crank 12 and connecting rod 13 structure, so as to achieve flexible adjustment of the cleaning force of the scraper.

[0030] In some embodiments, according to Figure 4-6As shown, a support frame 14 hinged to the crankshaft 11 is provided on one side of the connecting rod 13. Multiple horizontal plates 15 are fixedly provided at the bottom of the connecting rod 13. A sliding groove 16 is fixedly provided inside the horizontal plate 15. A telescopic rod 17 is fixedly provided on one side of the horizontal plate 15. A spring 21 fixedly connected to the horizontal plate 15 is fixedly provided inside the telescopic rod 17. A slider 18 is fixedly provided at one end of the spring 21. After the telescopic rod 17 inside the horizontal plate 15 extends and retracts, it drives the slider 18 fixedly connected to it to move horizontally on the sliding groove 16, thereby realizing the horizontal movement of the main scraper 19 and the auxiliary scraper 23.

[0031] In some embodiments, according to Figure 7-9 As shown, a main scraper 19 is fixedly mounted on the top of slider 18, a spring fixing rod 20 is fixedly mounted on one side of the main scraper 19, a spring 21 is fixedly mounted inside the spring fixing rod 20, and a fixing block 22 is fixedly mounted on one side of the spring 21. When the main scraper 19 and the auxiliary scraper 23 slide downwards, the diameter of the sedimentation tank becomes smaller. The fixing block 22, which is fixedly connected to the auxiliary scraper 23, will drive the slider 24 at the bottom of the auxiliary scraper 23 to move and contract on the slide rail 25 under the action of the spring 21 inside the spring fixing rod 20, so as to adapt to the size of the inner wall of the sedimentation tank.

[0032] In some embodiments, according to Figure 7-9 As shown, a secondary scraper 23 is fixedly provided on the top of the fixed block 22, and a slider 24 is fixedly provided on the bottom of the secondary scraper 23. The bottom of the slider 24 is provided with a slide rail 25 that is fixedly connected to the column scraper. The slide rail 25 allows the slider 24 to slide and drive the secondary scraper 23 to unfold and move on the main scraper 19.

[0033] In some embodiments, according to Figure 1-3 As shown, a number of heat dissipation holes 26 are fixedly provided on one side of the motor mounting bracket 8. The heat dissipation holes 26 can dissipate the heat generated by the generator 10 during operation in a timely manner, so as to avoid the motor 10 from becoming less efficient or malfunctioning due to high temperature. Two sedimentation tanks 9 are fixedly connected to the housing 1 at the bottom of the heat dissipation holes 26. The cross-section of the sedimentation tank 9 is set as a cone. Compared with the single sedimentation tank 9 design, the double tank structure not only increases the processing capacity, but also makes the scraper cleaning more efficient by dispersing the impurity load. A sludge discharge pipe 27 is fixedly provided on one side of the bottom of the sedimentation tank 9, and a sludge discharge pump 28 is fixedly provided on one side of the sludge discharge pipe 27.

[0034] In some embodiments, according to Figure 1As shown, a left support leg 29 is fixedly provided at the bottom of the shell 1. The cross-section of the left support leg 29 is L-shaped. The L-shaped left support leg 29 is fixed to the bottom of the shell 1 through two mutually perpendicular force-bearing surfaces. The contact area is large and the force is distributed, which can provide stable support for the processing area on the left side of the shell 1. A right support leg 30 is fixedly connected to the shell 1 on one side of the left support leg 29. The right support leg 30 is set as a cylinder. The cylindrical right support leg 30 evenly bears the weight of the heavy load area such as the sedimentation tank 9 and the sludge pump 28 on the right side of the shell 1 through the arc surface, taking into account both load-bearing capacity and anti-tilting ability.

[0035] In some embodiments, according to Figure 1-10 As shown, a drug outlet pipe 31 is fixedly provided on one side of the dosing tank 4, a conveying plate 32 is fixedly provided on one side of the reaction tank 5, and a support frame 14 is fixedly connected to the reaction tank 5 on one side and to the shell 1 on the other side.

[0036] The working principle of this utility model is as follows: When this utility model is working, the prepared liquid reagent solution is first poured into the dosing tank 4 in a certain proportion, and then enters the reaction tank 5 through the dosing pipe 31. Then, the wastewater is poured into the reaction tank 5 through the water inlet pipe 2. After the wastewater and the reagent solution have reacted, the liquid flows from the conveying plate 32 into the right side of the shell 1. The evenly distributed water flow enters the densely arranged inclined tubes 6. In the internal space of the inclined tubes 6, the coal sludge, flocs and other sediments attached to the inner wall of the inclined tubes 6 slide down the inclined surface of the inclined tubes 6 under the slight push of gravity and the subsequent water flow, and finally fall into the sedimentation tank 9 below the inclined tubes 6. The sedimentation tank 9 at the bottom of the tank is designed to be conical. The sludge gathers to the center of the bottom of the tank under the action of gravity. Then, the sludge discharge pump 28 is started to discharge the sludge from the sludge outlet pipe 27, and the clean water is discharged and collected from the water outlet pipe 3.

[0037] During the use of the sludge pump 28, a small amount of sludge will adhere to the inner wall of the sedimentation tank 9. At this time, the motor 10 on the motor mounting bracket 8 can be started. The output end of the motor 10 will rotate the crankshaft 11 inside the support bracket 14, causing the crank 12 fixedly connected to the crankshaft 11 to rotate. This will drive the connecting rod 13, which is rotated with the crank 12, to move vertically. The horizontal plate 15, which is fixedly connected to the connecting rod 13, will also move up and down. After the telescopic rod 17 inside the horizontal plate 15 extends and retracts, it will drive the slider 18 fixedly connected to it to slide in the groove. The horizontal movement of the 16-axis enables the main scraper 19 and the auxiliary scraper 23 to move horizontally. When sliding downwards, the diameter of the sedimentation tank decreases. The fixed block 22, which is fixedly connected to the auxiliary scraper 23, will drive the slider 24 at the bottom of the auxiliary scraper 23 to move and contract on the slide rail 25 under the action of the spring 21 in the spring fixing rod 20. During the up and down movement, the main scraper 19 and the auxiliary scraper 23 expand and contract within the constraints of the internal structure of the sedimentation tank to achieve full-range cleaning of the inner wall of the sedimentation tank, thereby completing the coal slime cleaning process of the entire device.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
