Description

Technical Field

[0001] This utility model relates to the field of thickener technology, specifically a thickener for heavy sedimentation and sludge discharge. Background Technology

[0002] Heavy sedimentation, also known as heavy media coagulation sedimentation, refers to the simultaneous addition of inert high-density microparticles, i.e., heavy media powder, as a flocculant during ordinary coagulation sedimentation processes to accelerate floc formation and sedimentation. A thickener is a device used to treat wastewater. By concentrating the dissolved substances in wastewater, it reduces the volume of wastewater and treatment costs. Its working principle utilizes the difference in solubility of substances to form a concentrated liquid and a diluted liquid, which are then separated through evaporation, condensation, and other methods. Thickeners are used in wastewater treatment, resource recovery, and energy recovery, improving wastewater treatment efficiency and comprehensive utilization benefits.

[0003] In existing technologies, flocculants need to be manually added to the thickener during use, which reduces the sedimentation efficiency of the thickener and makes it easy for sludge to accumulate at the bottom and be difficult to remove, thus reducing the practicality of the thickener. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a thickening tank for heavy sedimentation and sludge discharge, including a sedimentation tank, and an automatic processing mechanism is provided inside the sedimentation tank.

[0006] The automatic processing mechanism includes a sealing cover, which is fixedly connected to the top of the sedimentation tank. A drive motor is fixedly connected to the middle of the top wall of the sealing cover. A transmission rod is fixedly connected to the output shaft of the drive motor. Mounting frames are fixedly connected to both the left and right sides of the outer periphery of the transmission rod. Multiple sets of evenly distributed stirring teeth are provided inside the mounting frames. A conveying pipe is passed through and fixedly connected to the front end of the middle of the top wall of the sealing cover. A booster pump is provided in the lower part of the conveying pipe. A water pumping pipe is passed through and fixedly connected to the right side of the middle of the top wall of the sealing cover.

[0007] As a preferred embodiment of this utility model, the input end of the conveying pipe is connected through and fixedly connected to the middle of the top wall of the storage tank, and the storage tank is fixedly connected to the top of the base.

[0008] As a preferred technical solution of this utility model, the lower left and right ends of the rear wall of the base are fixedly connected with connecting rods, and the connecting rods are respectively fixedly connected to the left and right sides of the middle of the front wall of the support frame.

[0009] As a preferred embodiment of this utility model, a sludge discharge pipe is provided at the bottom of the middle part of the rear wall of the sedimentation tank, and an inspection door is provided at the lower middle part of the left wall of the sedimentation tank.

[0010] As a preferred embodiment of this utility model, a water pump is provided at the output end of the water pumping pipe, and the water pump is fixedly connected to the right side wall of the support frame.

[0013] The beneficial effects of this utility model are:

[0014] 1. This type of heavy sedimentation sludge thickening tank allows the flocculant inside the storage tank to be fed into the sedimentation tank through the conveying pipe by starting the booster pump. Then, the drive motor is started, and the output shaft of the drive motor rotates, causing the transmission rod and the mounting frame to rotate, which in turn causes the stirring teeth inside the mounting frame to rotate, mixing the sewage and flocculant inside the sedimentation tank.

[0015] 2. This type of heavy sedimentation sludge thickening tank, by setting the bottom of the sedimentation tank to a slope with the same angle as the inclined plate, allows the sludge at the bottom to slide along the slope during sedimentation and be discharged from the sludge discharge pipe, thus avoiding sludge accumulation at the bottom of the sedimentation tank and causing blockage of the sludge discharge pipe, and improving the material discharge rate of the thickening tank.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figure 1-4 As shown, the present invention provides a thickening tank for heavy sedimentation and sludge discharge, including a sedimentation tank 1, and an automatic processing mechanism 2 is provided inside the sedimentation tank 1.

[0024] The automatic processing mechanism 2 includes a sealing cover 3, which cooperates with the sedimentation tank 1 to prevent sewage from spilling out from the top of the sedimentation tank 1. The sealing cover 3 is fixedly connected to the top of the sedimentation tank 1. A drive motor 4 is fixedly connected to the middle of the top wall of the sealing cover 3. The drive motor 4 is the power source of the mixing component. During the operation of the drive motor 4, the transmission rod 5 and the mounting frame 6 can rotate, thereby causing the stirring teeth 7 to rotate. The output shaft of the drive motor 4 is fixedly connected to the transmission rod 5. The mounting frames 6 are fixedly connected to both the left and right sides of the outer periphery of the transmission rod 5. Multiple sets of evenly distributed stirring teeth 7 are provided on the inner side of the mounting frames 6. A conveying pipe 13 is passed through and fixedly connected to the front end of the middle of the top wall of the sealing cover 3. A booster pump 14 is provided in the lower part of the conveying pipe 13. During the operation of the booster pump 14, the flocculant inside the storage tank 12 can be discharged into the sedimentation tank 1 through the conveying pipe 13. A water pumping pipe 15 is passed through and fixedly connected to the right side of the middle of the top wall of the sealing cover 3. The water pumping pipe 15 is used to extract the clear water after sedimentation and separation.

[0025] The material conveying pipe 13 has its input end connected through and fixedly connected to the middle of the top wall of the storage tank 12. The storage tank 12 is fixedly connected to the top of the base 11, and the storage tank 12 is installed and fixed through the base 11.

[0026] Among them, the lower left and right ends of the rear wall of the base 11 are fixedly connected to the connecting rods 10. The connecting rods 10 are respectively fixedly connected to the left and right sides of the middle of the front wall of the support frame 9. The connecting rods 10 serve to connect and fix the base 11 and the support frame 9.

[0027] The sedimentation tank 1 has a sludge discharge pipe 8 at the bottom of the middle of the rear wall and an inspection door 17 at the lower middle of the left wall. The internal components of the sedimentation tank 1 can be inspected and repaired by opening the inspection door 17.

[0028] The pump 16 is installed at the output end of the pumping pipe 15. The pump 16 is fixedly connected to the right side wall of the support frame 9. When the pump 16 is working, the pumping pipe 15 can extract water from the inside of the sedimentation tank 1.

[0029] The sedimentation tank 1 is fixedly connected to the top of the inclined plate 20, and the inclined plate 20 is fixedly connected to the top of the support frame 9. The support frame 9 can support and fix the inclined plate 20 and its upper components.

[0030] The sedimentation tank 1 has a hopper 18 in the middle of its bottom wall and a discharge pipe 19 at the bottom of the hopper 18.

[0031] Working principle: Starting the booster pump 14 allows the flocculant inside the storage tank 12 to be sent into the sedimentation tank 1 through the conveying pipe 13. Then, starting the drive motor 4 causes the output shaft of the drive motor 4 to rotate, which in turn causes the transmission rod 5 and the mounting frame 6 to rotate, thereby causing the stirring teeth 7 inside the mounting frame 6 to rotate. This mixes the sewage and flocculant inside the sedimentation tank 1, allowing the sewage to settle. After that, starting the water pump 16 discharges the relatively clear water at the top of the sedimentation tank 1 through the water pumping pipe 15, thus automating the entire purification process. The bottom of the sedimentation tank 1 is set as a slope with the same angle as the inclined plate 20, which allows the sludge at the bottom to slide along the slope during sedimentation and be discharged from the sludge discharge pipe 8, preventing sludge from accumulating at the bottom of the sedimentation tank 1 and causing blockage of the sludge discharge pipe 8.
