Description

Technical Field

[0001] This utility model relates to the field of coal chemical wastewater treatment technology, and in particular to a sedimentation treatment device for high-salt coal chemical wastewater. Background Technology

[0002] The sedimentation treatment unit for high-salt wastewater from coal chemical industry mainly utilizes physical sedimentation to remove suspended solids and some dissolved substances from the wastewater. After the wastewater enters the unit, chemical reagents are added to cause impurities to precipitate. The precipitate gradually sinks under gravity, thus separating from the supernatant. The supernatant can be further treated or discharged, while the precipitate is discharged from the unit through the sludge removal system.

[0003] Existing processing devices typically use a single motor to drive a stirring device for stirring. In order to maintain a full reaction, the motor usually drives the stirring device to rotate at high speed. During this process, the formed precipitate is easily resuspended. Therefore, there is a need to provide a processing device that can perform multi-stage stirring at different speeds to avoid the resuspension of precipitate. Utility Model Content

[0004] The purpose of this utility model is to provide a sedimentation treatment device for high-salt wastewater from coal chemical industry, in order to solve the problem mentioned in the background art, where existing treatment devices usually use a single motor to drive a stirring device for stirring. In order to maintain a full reaction, the motor usually drives the stirring device to rotate at high speed, which can easily lead to the re-suspension of the formed precipitate.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a sedimentation treatment device for high-salt wastewater from coal chemical industry, comprising:

[0007] The main component includes a processing tank and a partition. The partition is fixedly installed in the middle of the processing tank, dividing the upper and lower ends of the processing tank into a first stirring zone and a second stirring zone, respectively. A multi-stage stirring assembly includes a high-speed motor, a first rotating rod, a first stirring wheel, a low-speed motor, a second rotating rod, and a second stirring wheel. The high-speed motor is fixedly connected to the top of the processing tank. The output end of the high-speed motor is connected to the first rotating rod. The bottom of the first rotating rod is fixedly connected to the first stirring wheel. The bottom of the partition is fixedly connected to the low-speed motor. The output end of the low-speed motor is connected to the second rotating rod. The bottom of the second rotating rod is fixedly connected to the second stirring wheel.

[0008] Furthermore, the multi-stage stirring assembly also includes a first through hole, the middle of which is movably connected to a first rotating rod.

[0009] Furthermore, the main component also includes a wastewater injection pipe, a reactant injection pipe, a water pump receiving pipe, a filter box, and a sediment discharge pipe. The wastewater injection pipe is fixedly inserted into the top left of the treatment box, and the reactant injection pipe is fixedly inserted into the top right of the treatment box. One end of the water pump receiving pipe is connected to the right side of the treatment box, and the other end of the water pump receiving pipe is fixedly connected to the filter box. The sediment discharge pipe is fixedly connected to the bottom of the treatment box.

[0010] Furthermore, it also includes a flow regulating component, which includes a feed hole, a rectangular plate, and a conical block. The feed hole is provided on the partition plate. The rectangular plate is movably connected to the first stirring zone of the processing box. The conical block is fixedly connected to the bottom of the rectangular plate. The conical block movably passes through the feed hole.

[0011] Furthermore, the flow regulating assembly also includes a hydraulic actuator and a hydraulic rod. The hydraulic actuator is fixedly installed on the top of the processing box, one end of the hydraulic rod is fixedly connected to the bottom of the hydraulic actuator, and the other end of the hydraulic rod is fixedly connected to a rectangular plate.

[0012] Furthermore, the flow regulating component also includes a second through hole, through which a hydraulic rod is inserted.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] In this invention, when wastewater enters the first mixing zone, a high-speed motor is turned on to drive the first mixing wheel to rotate at high speed, so that the chemical reagent and wastewater are quickly and thoroughly mixed. As the reaction proceeds, the mixture after the reaction is passed into the second mixing zone through the feed hole. Then, a low-speed motor is turned on to drive the second mixing wheel to rotate at low speed, reducing the mixing intensity and thus avoiding over-mixing that would cause the formed precipitate to be resuspended.

[0015] Based on the aforementioned beneficial effects, by controlling the hydraulic actuator, the hydraulic rod can drive the rectangular plate and the conical block to move up and down, thereby adjusting the gap between the conical block and the feed hole, and thus adjusting the flow rate of the mixture from the first mixing zone to the second mixing zone. According to the characteristics of wastewater and different chemical agents, the residence time of wastewater in the first mixing zone can be precisely controlled to ensure that the reaction is complete. When wastewater needs to be mixed with chemical agents for a longer time, the flow rate can be reduced to prolong the reaction time; conversely, the flow rate can be increased to speed up the treatment process.

[0032] The first through hole 207 provides a guarantee for the insertion and rotation of the first rotating rod 202.

[0033] The main components also include a wastewater injection pipe 103, a reactant injection pipe 104, a water pump receiving pipe 105, a filter box 106, and a sediment discharge pipe 107. The wastewater injection pipe 103 is fixedly inserted into the top left of the treatment box 101, the reactant injection pipe 104 is fixedly inserted into the top right of the treatment box 101, one end of the water pump receiving pipe 105 is connected to the right side of the treatment box 101, the other end of the water pump receiving pipe 105 is fixedly connected to the filter box 106, and the sediment discharge pipe 107 is fixedly connected to the bottom of the treatment box 101.

[0034] Wastewater injection pipe 103 and reaction material injection pipe 104 are used to inject wastewater and chemical reaction reagents, respectively.

[0035] It also includes a flow regulating component, which includes a feed hole 301, a rectangular plate 302 and a conical block 303. The feed hole 301 is opened on the partition plate 102. The rectangular plate 302 is movably connected to the first mixing zone of the processing box 101. The bottom of the rectangular plate 302 is fixedly connected to the conical block 303. The conical block 303 movably passes through the feed hole 301.

[0036] The feed passage 301 and the conical block 303 work together to ensure the flow rate regulation of the material entering the second mixing zone from the first mixing zone.

[0037] The flow regulation assembly also includes a hydraulic actuator 304 and a hydraulic rod 305. The hydraulic actuator 304 is fixedly installed on the top of the processing box 101, and one end of the hydraulic rod 305 is fixedly connected to the bottom of the hydraulic actuator 304.

[0041] Working principle: First, wastewater is injected into the first stirring zone of the treatment tank 101 through the wastewater injection pipe 103. Then, chemical reagents are injected into the first stirring zone through the reactant injection pipe 104. The high-speed motor 201 is turned on wirelessly, driving the first rotating rod 202 and the first stirring wheel 203 to rotate at high speed, achieving a thorough mixing reaction of the wastewater and chemical reagents. Then, the hydraulic actuator 304 is turned on, and with the cooperation of the hydraulic rod 305, the rectangular plate 302 and the conical block 303 are slowly moved upward. When they move to the appropriate position, the hydraulic actuator 304 is turned off. At this time, the conical block 303 and the feed hole 301 are closed. A gap is formed between the two, and the mixture enters the second stirring zone through the gap. Then, the low-speed motor 204 is turned on by the wireless device, which drives the second rotating rod 205 and the second stirring wheel 206 to rotate at a low speed, so that the wastewater and chemical reaction reagents are kept mixed. Subsequently, the precipitate in the wastewater settles at the bottom of the treatment tank 101. The water pump receiving pipe 105 is opened to pump the supernatant after the wastewater sedimentation into the filter tank 106 for further treatment. The precipitate is discharged through the precipitate discharge pipe 107. This step can avoid excessive stirring and resuspend the formed precipitate. At the same time, the flow rate can be adjusted according to the reaction characteristics of the wastewater and different chemical reagents.
