Description

Technical Field

[0001] The invention relates to the technical field of electroplating pool wastewater treatment, in particular to a device for filtering and recycling wastewater from electroplating and zinc plating pools. Background Art

[0002] At present, there are various methods for treating electroplating wastewater in China, and each has its own advantages. The main methods include chemical method, ion exchange method, membrane separation method (reverse osmosis, electrodialysis, diffusion dialysis, liquid membrane method, ultrafiltration method), extraction method, electrolysis method, biological method, etc. Among them, the precipitation method is relatively simple. It only needs to let the wastewater stand, let the particles in the wastewater settle and gather by gravity, and then collect the supernatant to complete it.

[0003] In the process of treating electroplating pool wastewater, the sedimentation method mainly relies on the sinking of large particles to achieve the effect of treating wastewater. Small particles are tiny and sink slowly. In addition, since purification mainly relies on sedimentation treatment, small particles that fail to precipitate in time will appear, which is not conducive to the thorough treatment of electroplating wastewater. Summary of the invention

[0004] The object of the present invention is to provide a device for filtering and recycling wastewater from an electroplating and zinc plating pool to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for filtering and recycling wastewater from an electroplating and galvanizing pool, comprising a sedimentation tank, wherein the sedimentation tank comprises a treatment chamber, a water injection chamber and a water diversion channel, and further comprising: a filter assembly, wherein the filter assembly is arranged inside the treatment chamber; a plurality of attachment plates, wherein the plurality of attachment plates are distributed in a linear array and are arranged obliquely, wherein the bottom ends of the plurality of attachment plates are rotatably connected to a support frame, wherein the support frame is fixedly mounted on the inner wall of the treatment chamber; a plurality of cleaning members, wherein the plurality of cleaning members are respectively slidably sleeved on the top ends of the plurality of attachment plates; a driving assembly, wherein the driving assembly is used to drive the cleaning members to scrape the surface of the attachment plates during the cleaning process, while causing the attachment plates to flip and change; specifically, a drain pipe is fixedly connected to the top end of the side wall of the treatment chamber, wherein the drain pipe is located above the filter assembly, and a water inlet pipe is fixedly connected to the bottom end of the inner side wall of the water injection chamber; and the water diversion channel connects the water injection chamber with the treatment chamber;

[0006] It should be understood that the wastewater from the electroplating pool enters the treatment chamber from the water injection chamber through the water diversion channel. The water diversion channel is set so that the wastewater injected into the water injection chamber flows into the treatment chamber, reducing the impact of the shaking generated during water injection on the wastewater in the treatment chamber.

[0007] After the treatment chamber is filled with water, it is precipitated. During the precipitation process, large particles in the wastewater in the treatment chamber will sink to the bottom of the treatment chamber, and small particles will float upward. Some of the small particles will adhere to the attachment plate, and the wastewater passing through the filter component will be filtered again to further filter the small particles, which is conducive to the thorough cleaning of electroplating wastewater.

[0008] After settling for a certain period of time, the driving component is started, and the driving component drives the cleaning component to scrape the surface of the attachment plate, so that the attached particles are scraped and cleaned, and the scraped attached particles will form large particles, causing the attachment plate to flip and change. The flipping attachment plate will actively collide with the wastewater during the flipping process, which is conducive to completely cleaning the substances attached to the attachment plate;

[0009] It should be further explained that, during cleaning, the flipping and swinging of the attachment plate will cause the wastewater to shake, which increases the chances of contact and collision between the particles being cleaned and in the wastewater, thereby promoting coagulation and precipitation of impurities in the wastewater.

[0010] As an optional embodiment of the present invention, the filter assembly includes:

[0011] A fixing seat, wherein the fixing seat is fixedly mounted on the inner wall of the processing chamber;

[0012] A filter plate is fixedly mounted on the fixing seat.

[0013] It should be understood that by setting up the filter plate, the water passing through the filter plate is further filtered and treated before being discharged, which is conducive to the thorough cleaning of the wastewater. Through the attachment treatment, it is helpful to reduce the filtering difficulty of the filter plate.

[0017] A rotary drive assembly is used to drive the outer gear ring to rotate.

[0018] It should be understood that after the filter plate filters the water after the attachment treatment, the filtered particulate matter will be attached to the filtering surface of the filter plate, and the rotating ring is driven to rotate by the rotating drive assembly, and the rotating ring synchronously drives the scraper to clean, so as to clean the particulate matter attached to the filter plate. The cleaned particulate matter is condensed during the attachment process. Therefore, after cleaning, the particulate matter will form large particles, so that the cleaned particles can sink.

[0019] As an optional embodiment of the present invention, the rotation drive assembly includes:

[0020] A motor, wherein the motor is fixedly mounted on the side wall of the sedimentation tank, and an output end thereof passes through the sedimentation tank and extends to the inside of the treatment chamber and is fixedly connected to a driving gear;

[0021] An intermediate gear, the intermediate gear being rotatably connected to the bottom of the fixing seat;

[0022] The specific structure of the rotating ring is an outer gear ring, and the outer gear ring is meshed with the driving gear.

[0023] It should be understood that when cleaning is required, the motor is started, the motor drives the driving gear to rotate, the driving gear drives the intermediate gear to rotate, and the intermediate gear drives the scraper to scrape under the transmission of the outer gear ring.

[0024] As a further optimized embodiment of the present invention, the plurality of scrapers are arranged at an angle to form an impeller with the rotating ring.

[0025] It should be understood that during the scraping process, since the scraper and the rotating ring form an impeller, the scraper and the rotating ring will push the water in the process of scraping and cleaning the filter plate, so that the water is pushed in the direction of the attachment plate, and the water flows toward the attachment plate, which is conducive to impacting the water on the surface of the attachment plate, and is conducive to flushing down the attached particles. The water flows through the gaps between the attachment plates, which is conducive to driving and cleaning the attached particles.

[0026] As an optional embodiment of the present invention, the driving assembly includes:

[0027] Two movable racks, opposite sides of the two movable racks are rotatably connected to two ends of the cleaning member respectively;

The linkage frame will move on the traction track, and the traction track will drive the traction pin to move in the guide track. The traction pin drives the cleaning piece to move on the surface of the attachment plate from the top to the bottom, so as to scrape and clean the particles attached to the surface of the attachment plate; during the scraping and cleaning process, the attachment plate will flip at the same time, so that the attachment plate has an active interaction with water, which is beneficial to further clean up the particles attached to the surface of the attachment plate; the scraping and cleaning of the cleaning piece and the cleaning of the scraper are carried out simultaneously. In the process of cleaning the attachment plate and the filter plate, the scraper realizes pushing the water downward, and the attachment plate actively collides with the pushed water during the flipping process, thereby increasing the collision intensity between the attachment plate and the water flow, which is beneficial to further clean up the particles attached to the surface of the attachment plate.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The driving component drives the cleaning part to scrape the surface of the attachment plate, so that the attached particles are scraped off, and the scraped attached particles will form large particles, causing the attachment plate to flip over. The flipped attachment plate will actively collide with the wastewater during the flipping process, which is conducive to completely cleaning the attached materials on the attachment plate;

[0035] During cleaning, the flipping and swinging of the attachment plate will cause the wastewater to shake, which increases the chances of contact and collision between the cleaned particles and the particles in the wastewater, thereby promoting coagulation and the precipitation of impurities in the wastewater.

[0036] 2. After the treatment chamber is filled with water, sedimentation is carried out. During the sedimentation process, large particles in the wastewater in the treatment chamber will sink to the bottom of the treatment chamber, and small particles will float upward. Some of the small particles will adhere to the attachment plate, and the wastewater passing through the filter component will be filtered again to further filter the small particles, which is conducive to the thorough cleaning of the electroplating wastewater.

[0037] 3. During the scraping process, since the scraper and the rotating ring form an impeller, the scraper and the rotating ring will push the water in the process of scraping and cleaning the filter plate, so that the water is pushed toward the attachment plate, and the water flows toward the attachment plate, which is conducive to impacting the water on the surface of the attachment plate, and is conducive to flushing down the attached particles. The water flows through the gaps between the attachment plates, which is conducive to driving and cleaning the attached particles. BRIEF DESCRIPTION OF THE DRAWINGS
