Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment production technology, specifically to an electrochemical wastewater treatment device. Background Technology

[0002] Current mainstream wastewater treatment technologies include biological methods, physical methods (such as sedimentation and filtration), and chemical methods (such as redox reactions). While these methods have achieved certain results, they generally suffer from high operating costs and secondary pollution. Electrochemical technology, which degrades pollutants under the influence of an applied current, offers advantages such as low energy consumption and simple operation. Specifically, the electrocoagulation-electroflotation method involves the soluble anode (typically aluminum or iron) generating cations under an external voltage. These cations coagulate colloidal pollutants. Simultaneously, the cathode releases a large amount of hydrogen gas under voltage, which carries the flocs to the surface, thus separating pollutants and purifying the water.

[0003] In existing technologies, when using electrochemical methods to treat wastewater, flocs tend to accumulate on the surfaces of the anode and cathode, affecting water treatment efficiency. Furthermore, after water purification, the upper layer of floc impurities needs to be manually removed before the purified water can be collected, making the operation complex. Utility Model Content

[0004] The technical problem this invention aims to solve is that flocs generated during water treatment tend to adhere to the electrodes, affecting electrolysis efficiency, and the purified water is inconvenient to collect and the operation is complex.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] An electrochemical wastewater treatment device includes a tank with several supporting legs fixed to its lower end. An electrolysis mechanism is provided in the tank, which includes a power source, an anode, and a cathode. The power source is located at the upper end of the tank, and power transmission lines are provided on both sides of the power source and connected to the anode and cathode, respectively. The device also includes a cleaning mechanism and a filtration mechanism both located in the tank. An inlet pipe is provided at the upper end of one side of the tank, and a collection pipe and a slag outlet pipe are symmetrically provided at the lower end of the tank. Both the collection pipe and the slag outlet pipe are equipped with control valves.

[0007] The cleaning mechanism includes a motor and a scraper frame. The motor is fixed to the upper end of the housing and drives the scraper frame to slide vertically inside the housing, which is fitted onto the anode and cathode.

[0008] The filtration mechanism includes a hydraulic rod and a mounting frame. The mounting frame is equipped with a filter screen. The hydraulic rod is fixed to the outside of the housing and drives the mounting frame to slide horizontally inside the housing.

[0009] Furthermore, a screw is fixedly connected to the output end of the motor, and a first support plate and a second support plate are symmetrically fixedly connected to the inner wall of the housing. The lower end of the screw is rotatably connected to the first support plate, and a slide rod is fixedly connected between the second support plate and the upper inner wall of the housing. One side of the scraper is threadedly connected to the screw, and the other side of the scraper is slidably connected to the slide rod.

[0010] Furthermore, the initial position of the scraper is attached to the upper end of the inner wall of the box, and the four sides of the outer wall of the scraper slide against the inner wall of the box. The scraper is provided with two through holes, and the anode and cathode are respectively slidably adapted to the two through holes.

[0011] Furthermore, the hydraulic rod is horizontally positioned and fixed to the outside of the housing, and connecting plates are symmetrically fixed to the inner wall of the mounting frame. The telescopic end of the hydraulic rod slides into the housing and is fixed to the connecting plates.

[0012] Furthermore, the lower end of the mounting frame is slidably attached to the bottom surface of the inner wall of the box, and the two sides of the mounting frame are slidably attached to the two sides of the inner wall of the box.

[0026] like Figure 1-4 As shown, an electrochemical wastewater treatment device includes a housing 1. Several support legs 101 are fixedly connected to the lower end of the housing 1. An electrolysis mechanism 2 is provided inside the housing 1. The electrolysis mechanism 2 includes a power supply 201, an anode 203, and a cathode 204. The power supply 201 is located at the upper end of the housing 1. Power transmission lines 202 are provided on both sides of the power supply 201 and are respectively connected to the anode 203 and the cathode 204. Mounting plates 205 are fixedly connected to the upper ends of both the anode 203 and the cathode 204. The mounting plates 205 are secured by bolts 206. Fixedly connected to the upper end of the housing 1, it also includes a cleaning mechanism 3 and a filtration mechanism 4 both disposed in the housing 1. An inlet pipe 102 is provided at the upper end of one side of the housing 1, and a collection pipe 105 and a slag outlet pipe 103 are symmetrically provided at the lower end of the housing 1. A control valve 104 is provided on both the collection pipe 105 and the slag outlet pipe 103. Wastewater is electrolyzed by the electrolysis mechanism 2, the anode 203, the cathode 204 and the inner wall of the housing 1 are scraped and cleaned by the cleaning mechanism 3, and the flocs produced by electrolysis are filtered by the filtration mechanism 4 to collect purified water.

[0027] like Figure 3 , 5As shown, the cleaning mechanism 3 includes a motor 301 and a scraper frame 304. The motor 301 is fixed to the upper end of the housing 1 and drives the scraper frame 304 to slide vertically within the housing 1, mounted on the anode 203 and cathode 204. A screw 302 is fixed to the output end of the motor 301. A first support plate 106 and a second support plate 107 are symmetrically fixed to the inner wall of the housing 1. The lower end of the screw 302 is rotatably connected to the first support plate 106. A slide rod 303 is fixed between the second support plate 107 and the upper inner wall of the housing 1. One side of the scraper frame 304 is threaded to the screw 302, and the other side of the scraper frame 304 is slidably connected to the slide rod 303. The initial position of the scraper 304 is attached to the upper end of the inner wall of the housing 1. The four sides of the outer wall of the scraper 304 slide against the inner wall of the housing 1. The scraper 304 is provided with two through holes 305. The anode 203 and cathode 204 are respectively slidably adapted to the two through holes 305. The motor 301 drives the scraper 304 to slide vertically against the inner wall of the housing 1, thereby scraping and cleaning the cathode 204, anode 203 and part of the inner wall of the housing 1, avoiding the adhesion of lint to the electrodes and the inner wall of the housing 1. The scraper 304 is made of flexible non-metallic material, such as rubber, to avoid excessive friction on the electrodes and damage. The lowest position of the scraper 304 touches the upper end of the mounting frame 402.

[0028] like Figure 3 , 6 As shown, the filter mechanism 4 includes a hydraulic rod 401 and a mounting frame 402. A filter screen 404 is provided in the mounting frame 402. The hydraulic rod 401 is fixed to the outside of the housing 1 and drives the mounting frame 402 to slide horizontally within the housing 1. The hydraulic rod 401 is horizontally positioned and fixed to the outside of the housing 1. Connecting plates 403 are symmetrically fixed to the inner wall of the mounting frame 402. The telescopic end of the hydraulic rod 401 slides into the housing 1 and is fixed to the connecting plate 403. The mounting frame 402... The lower end of the 02 slides against the bottom surface of the inner wall of the box 1, and the two sides of the mounting frame 402 slide against the two sides of the inner wall of the box 1. The initial position of the mounting frame 402 is against the inner wall of the box 1 that is connected to the liquid collection pipe 105. The mounting frame 402 with the filter screen 404 is initially set in the box 1 on the side connected to the liquid collection pipe 105. Thus, when the purified water is collected through the liquid collection pipe 105, the flocs can be filtered, and after the purified water is collected, the flocs can be pushed out through the slag discharge pipe 103.

[0029] In use, wastewater is introduced into the tank 1 through the inlet pipe 102. The wastewater is then treated by the electrolysis mechanism 2. The soluble anode 203 (usually aluminum or iron) generates cations, which can coagulate colloidal pollutants. Simultaneously, the cathode 204 releases a large amount of hydrogen gas under voltage. As the hydrogen gas rises, it carries the flocs to the surface, achieving pollutant separation and water purification. The open inlet pipe 102 balances the air pressure inside the tank 1 (or a constant pressure valve is installed to achieve air pressure balance inside the tank 1). The output of the motor 301 drives the screw 302 to rotate. At the same time, under the sliding limit action of the sliding scraper 304, the scraper 304 slides vertically inside the tank 1, thereby scraping and cleaning the anode 203 and cathode 204, preventing the anode 203 and cathode 204 from colliding during wastewater treatment by the electrolysis mechanism 2. 4. Adhesive impurities: After water treatment, the collection pipe 105 is opened through the control valve 104 to collect purified water. After the purified water is collected, the scraper 304 is used again to scrape and clean the anode 203, cathode 204 and the upper part of the inner wall of the tank 1 until the lower end of the scraper 304 touches the upper end of the mounting frame 402. The slag outlet pipe 103 is opened through the control valve 104. Then, the hydraulic rod 401 is used to push the mounting frame 402, so that the mounting frame 402 slides against the inner wall of the tank 1 to scrape and discharge the flocculent impurities from the slag outlet. Clean water can be used during cleaning to promote the cleaning effect inside the tank 1.
