Description

Technical Field

[0001] This utility model belongs to the field of electrophoresis waste liquid purification and treatment technology, and more specifically, it relates to a high-efficiency waste liquid purification system for processing. Background Technology

[0002] When purifying electrophoresis wastewater, it is necessary to separate the sludge and water through flocculation and sedimentation before further purification. For example, patent application number CN202110481535.5 discloses an electrophoresis processing wastewater purification system, including a surface conditioning phosphating wastewater tank, a flocculation reaction device, a multi-media mechanical filter, and a plate and frame filter press. The surface conditioning phosphating wastewater tank is used to initially remove metal ions and phosphate ions from the electrophoresis processing wastewater; the flocculation reaction device removes most of the suspended solids and surfactants from the electrophoresis processing wastewater through sludge-water separation; the multi-media mechanical filter is used for fine filtration of the wastewater after sludge-water separation. This invention, through the setting of the pusher plate, enables the pusher plate to push the sludge off the filter plate surface, reducing the sludge adhering to the filter cloth surface. On the one hand, it avoids sludge accumulation on the filter cloth surface, thereby improving the filtration effect of the filter cloth; on the other hand, it avoids the continuous accumulation of bacteria in the sludge on the filter cloth surface, preventing bacterial corrosion of the filter cloth and thus improving the service life of the filter cloth.

[0003] In existing electrophoresis wastewater purification treatment, the flocculation reaction device used has a problem: the flocculant and the wastewater to be treated are introduced into the treatment cylinder in batches. This leads to the stratification of the flocculant and the wastewater, resulting in slow mixing efficiency and poor mixing uniformity during subsequent stirring and mixing, thus limiting its practicality.

[0028] The flocculation reaction device includes a container assembly 1, a mixing assembly 2, a pump assembly 3, and a drive motor 4. The container assembly 1 includes a processing cylinder 101 and a storage cylinder 102. The processing cylinder 101 is fixedly installed on the top of the storage cylinder 102, and the storage cylinder 102 stores flocculation treatment solution inside. The mixing assembly 2 includes a drive base 201 and a stirring shaft 202. The drive base 201 is rotatably connected to the bottom of the storage cylinder 102, and the stirring shaft 202 is fixedly installed on the top of the drive base 201. The shaft of the stirring shaft 202... The bodies are rotatably connected to the top of the storage tank 102 and the bottom of the processing tank 101 via sealed bearings, and the stirring shaft 202 is located inside the processing tank 101 with a stirring rod outside the shaft body; the pump assembly 3 includes a pump piston 301 and a drive gear 302, the pump piston 301 is inserted into the inside of the drive seat 201, and the drive gear 302 is rotatably connected to the inside of the drive seat 201; the drive motor 4 is fixedly installed at the bottom of the storage tank 102, and the rotating shaft of the drive motor 4 is connected to the bottom of the drive seat 201.

[0029] In this embodiment, the pumping assembly 3 is provided in two sets, and the two sets of pumping assemblies 3 are symmetrically arranged inside the drive seat 201. The drive seat 201 is provided with a piston chamber 2011, and the pumping piston 301 is inserted into the piston chamber 2011. The pumping piston 301 can only move up and down inside the piston chamber 2011, and the pumping pistons 301 of the two sets of pumping assemblies 3 are in opposite phases. In use, the drive motor 4 can drive the mixing assembly 2 to rotate inside the processing cylinder 101, so that when the stirring shaft 202 rotates, it can mix the medicine liquid and waste liquid inside the processing cylinder 101 through the external stirring rod. When the drive motor 4 rotates, the drive motor 4 can drive the drive seat 201 to rotate synchronously. When the drive seat 201 rotates, it can drive the stirring shaft 202 to rotate, thereby realizing the mixing operation of medicine liquid and waste liquid, which is convenient and flexible to use.

[0030] In this embodiment, the bottom of the pump piston 301 is provided with a reciprocating spiral groove 3011, and the inside of the drive gear 302 is provided with a drive protrusion 3021. The drive protrusion 3021 is inserted into the inside of the reciprocating spiral groove 3011. In use, the pump assembly 3 can pump the agent inside the storage tank 102 into the processing tank 101 during the stirring and mixing process. The agent can be pumped into different depths of the waste liquid inside the processing tank 101 in a layered manner. When the drive seat 201 rotates, it can drive the pump assembly 3 inside it to rotate accordingly. The inside of the storage tank 102 is provided with a follower rack 1021, and the follower rack 1021 and the drive gear 302 mesh and drive each other. The pump assembly 3 rotates with the drive seat 201. When in motion, the follower rack 1021 can drive the drive gear 302 to rotate. When the drive gear 302 rotates, it drives the protrusion 3021 to drive the pump piston 301 to move up and down reciprocally inside the piston chamber 2011 through the reciprocating spiral groove 3011. This realizes the function of extracting the liquid from the storage tank 102 and pumping it into the treatment tank 101. It is convenient and flexible to use. The drain channel 2021 extends into the inside of each stirring rod, so that the liquid can be completely discharged from the inside of the stirring rod into the waste liquid. This realizes the layered discharge of liquid into the waste liquid for mixing treatment. The mixing efficiency of liquid and waste liquid is fast and the mixing uniformity is high. It does not require additional pump mechanical drive, reducing energy input and saving energy and protecting the environment.

[0031] In this embodiment, the top of the piston chamber 2011 is provided with a liquid extraction channel 2012 and a liquid supply channel 2013. The liquid extraction channel 2012 connects the top of the piston chamber 2011 and the interior of the liquid storage cylinder 102. The interior of the stirring shaft 202 is provided with a liquid discharge channel 2021, which extends to the stirring rod. The liquid supply channel 2013 connects the top of the piston chamber 2011 and the bottom of the liquid discharge channel 2021. Both the liquid extraction channel 2012 and the liquid supply channel 2013 are provided with one-way valves to control the liquid flow direction. In use, when the pumping piston 301 moves downward inside the piston chamber 2011, the liquid storage cylinder 102 is filled with liquid. The liquid medicine inside the cylinder 102 can be drawn into the piston chamber 2011 through the liquid extraction channel 2012. When the pump piston 301 moves upward inside the piston chamber 2011, the liquid medicine inside the piston chamber 2011 can enter the discharge channel 2021 through the liquid supply channel 2013, and be discharged into the waste liquid through the opening of the discharge channel 2021 inside the stirring rod. It is convenient and flexible to use. Moreover, the pump pistons 301 of the two sets of pump components 3 are used in opposite phases, that is, the movement directions of the two pump pistons 301 are always opposite, so as to realize the function of continuous and uninterrupted pumping and discharging of liquid medicine, further improving the flexibility of the device.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In this invention, flocculation treatment solution for electrophoresis waste liquid treatment is added to the inside of the storage tank 102, and then the waste liquid is discharged into the treatment tank 101. Flocculation treatment can then be initiated by turning on the drive motor 4. The drive motor 4 drives the mixing component 2 to rotate inside the treatment tank 101. Thus, when the stirring shaft 202 rotates, it can mix the solution and waste liquid inside the treatment tank 101 via an external stirring rod. When the drive motor 4 rotates, it drives the drive base 201 to rotate synchronously. The rotation of the drive base 201, in turn, drives the stirring shaft 202 to rotate, thereby achieving the mixing of the solution and waste liquid. During the mixing operation, the pump assembly 3 can pump the agent inside the storage tank 102 into the processing tank 101 during the stirring and mixing process. The agent can be pumped into different depths of the waste liquid inside the processing tank 101 in a layered manner. When the drive seat 201 rotates, it can drive the pump assembly 3 inside it to rotate as well. When the pump assembly 3 rotates with the drive seat 201, the follower rack 1021 can drive the drive gear 302 to rotate. When the drive gear 302 rotates, the drive protrusion 3021 can drive the pump piston 301 to move up and down reciprocally inside the piston cavity 2011 through the reciprocating spiral groove 3011, thereby realizing... The system features a convenient and flexible function that draws liquid from the storage tank 102 and pumps it into the treatment tank 101. The discharge channel 2021 extends into the interior of each stirring rod, ensuring that all the liquid is discharged from the stirring rods into the waste liquid. This achieves a stratified mixing process, resulting in rapid and uniform mixing of the liquid and waste liquid without the need for additional pumps, thus reducing energy consumption. When the pumping piston 301 moves downwards within the piston chamber 2011, the liquid from the storage tank 102 is drawn into the piston chamber 2011 through the extraction channel 2012. Inside the piston cylinder 101, when the pump piston 301 moves upward inside the piston chamber 2011, the liquid medicine inside the piston chamber 2011 can enter the interior of the discharge channel 2021 through the supply channel 2013, and be discharged into the waste liquid through the opening of the discharge channel 2021 inside the stirring rod. It is convenient and flexible to use. Moreover, the pump pistons 301 of the two sets of pump components 3 are used in opposite phases, that is, the movement directions of the two pump pistons 301 are always opposite, so as to realize the function of continuous and uninterrupted pumping and discharging of liquid medicine. After the waste liquid is flocculated, it can be discharged from the interior of the treatment cylinder 101 and the next purification treatment operation can be carried out.
