Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and specifically to an industrial wastewater filter based on electrolytic membrane technology. Background Art

[0002] Industrial wastewater includes production wastewater, production waste liquid and cooling water, which refers to the wastewater and waste liquid generated during industrial production, containing industrial production materials, intermediate products, by-products and pollutants generated during the production process that are lost with water; industrial wastewater has a wide variety and complex composition; since industrial wastewater often contains various toxic substances, it pollutes the environment and poses a great harm to human health. Therefore, comprehensive utilization should be developed to turn harm into benefit, and corresponding purification measures should be taken according to the components and concentrations of pollutants in the wastewater before it can be discharged. In the prior art, when treating industrial wastewater, electrolysis is usually selected to precipitate heavy metal substances in the wastewater to achieve the purpose of purifying the wastewater. During electrolysis, to increase the electrolysis speed, the cathode plate is usually made uneven or perforated to increase the electrolysis speed. This may cause the generated metal flocs to usually adsorb above the cathode plate and be difficult to clean. And after the wastewater treatment is completed, the precipitate needs to be filtered. The existing devices usually directly discharge the precipitate through the sewage outlet. Such a method usually discharges a mixture of precipitate and water, and secondary treatment is still required, resulting in an increase in workload. Summary of the Invention

[0003] The purpose of the present invention is to provide an industrial wastewater filter based on electrolytic membrane technology to solve the problems raised in the above background art.

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is an industrial wastewater filter based on electrolytic membrane technology, including a box body. The box body includes a cathode chamber. In the center of the upper surface of the cathode chamber, there is a fixed connection with an installation cylinder. Above the upper surface of the cathode chamber, there is a servo motor. The servo motor is fixedly installed inside the bracket, and the bracket is fixedly installed on the upper surface of the cathode chamber. The lower surface of the cathode chamber is fixedly installed with a bottom plate, and circular grooves are fixedly connected to the four corners of the bottom plate. It also includes: a cleaning mechanism, which includes a rotating shaft and two groups of small gears. The rotating shaft is fixedly installed on the output end of the servo motor, and the two groups of small gears are symmetrically distributed around the center of the rotating shaft; a sewage discharge mechanism, which includes a sewage discharge funnel and an electric motor. The sewage discharge funnel is fixedly installed on the lower surface of the bottom plate, and the electric motor is arranged on the side of the bottom plate away from the cathode chamber.

[0005] Further, a water inlet groove is formed in one side wall of the cathode chamber. A communication pipe is fixedly installed on the side wall of the cathode chamber along the contour of the water inlet groove. A diaphragm is fixedly installed inside the communication pipe. Two cathode plates are symmetrically arranged inside the cathode chamber. The cathode plates are perpendicular to the side wall of the cathode chamber where the water inlet groove is formed. The cathode plates are fixedly installed on two mounting seats, and the mounting seats are fixedly installed on the upper inner wall of the cathode chamber.

[0006] Further, two identical oval internal gear disks are arranged up and down inside the cathode chamber. The oval internal gear disks are fixedly installed between two pairs of connecting legs, and the connecting legs are fixedly installed on the inner side wall of the cathode chamber. The major axis of the oval internal gear disk is parallel to the two cathode plates.

[0007] Further, the rotating shaft penetrates through the installation cylinder and is rotatably arranged inside the installation cylinder. Fixed cylinders are fixedly installed at both ends of the rotating shaft. Cross bars are symmetrically and fixedly connected to the fixed cylinders. Sliding grooves are formed inside the cross bars. An installation ring is fixedly connected to the end of the rotating shaft far from the servo motor. A scraping plate that does not pass through the axis of the installation ring is fixedly connected to the side wall of the installation ring. A spiral blade is fixedly connected to the end of the rotating shaft far from the servo motor, and the spiral blade is arranged on the side of the installation ring far from the servo motor.

[0008] Further, small gears are fixedly connected to both ends of the vertical rod. A cleaning cylinder is fixedly installed in the middle of the vertical rod. A number of cleaning hairs are fixedly installed on the side wall of the cleaning cylinder.

[0009] Further, sliding rods are arranged at both ends of the vertical rod. Circular holes are formed at the ends of the sliding rods close to the vertical rod. The vertical rod is rotatably connected inside the circular holes. The small gears are located between the cleaning cylinder and the sliding rods. The sliding rods are slidably arranged inside the sliding grooves. A return spring is fixedly installed between the end of the sliding rod far from the small gear and the inner wall of the bottom of the sliding groove.

[0010] Further, one end of the sewage funnel far from the bottom plate is fixedly connected to a connecting cylinder. A sewage pipe is fixedly connected to the side of the connecting cylinder far from the sewage funnel. The sewage pipe is communicated with the sewage funnel through the connecting cylinder. One end of the sewage pipe is fixedly connected to a limiting cylinder.

[0011] Further, a circular plate is fixedly connected to the end of the sewage pipe far from the limiting cylinder. A pressure sensor is fixedly installed at the central axis of the side of the circular plate close to the limiting cylinder. A sewage outlet is formed on the side of the sewage pipe close to the circular plate and far from the bottom plate. A sealing plate is fixedly installed at the end of the sewage pipe far from the sewage outlet inside the sewage pipe.

[0012] Further, a support seat is fixedly installed on the side of the electric motor far from the bottom plate. The output end of the electric motor is fixedly connected to a screw rod. The screw rod penetrates through the water passing hole and the sealing plate and extends into the connecting cylinder. A threaded cylinder is in transmission connection with the screw rod. The threaded cylinder is slidably arranged inside the sewage pipe. A number of water passing holes are formed in the threaded cylinder.

[0013] Furthermore, a movable block is provided at one end of the screw away from the electric motor, and the movable block is slidably arranged inside the sewage pipe. An installation groove is opened on the side of the movable block away from the electric motor, and a trigger rod and a support spring are fixedly installed inside the installation groove, and a sealing plate is arranged inside the support spring.

[0014] The present invention has the following beneficial effects: (1) The present invention provides a cleaning mechanism. The servo motor drives the fixed cylinder and the cross bar to rotate synchronously through the transmission effect of the rotating shaft, so that the pinion can rotate synchronously with the sliding rod. Due to the transmission connection between the pinion and the elliptical inner toothed disk, the pinion can rotate around the rotating shaft, so that the cleaning cylinder can rotate synchronously. Through the setting of the shape of the elliptical inner toothed disk, when the pinion moves close to the elliptical inner toothed disk, the pinion will be squeezed and the reset spring will be compressed. When the pinion moves away from the elliptical inner toothed disk, the reset spring will extend. In addition, due to the setting of the length of the elliptical inner toothed disk, the surface of the elliptical inner toothed disk can be cleaned in all directions while the pinion moves.

[0015] (2) The present invention adopts a vortex blade arrangement. When the shaft rotates, the scraper and the vortex blade rotate synchronously. The scraper can drive the sediment deposited on the bottom plate to rotate synchronously. The scraper is inclined so that the sediment falls into the sewage funnel along the side wall of the scraper and is squeezed. The metal sediment can be rolled into the sewage pipe through the connecting tube.

[0016] (3) The sewage discharge mechanism of the present invention is set up. When the sediment accumulates to a certain extent, it will push the movable block to move, and the trigger rod will trigger the pressure sensor, which will then transmit the signal to the electric motor. The electric motor works and drives the screw to rotate, which can make the threaded barrel move toward the side close to the movable block, squeeze the sediment, and push the movable block to move synchronously. Then, the sediment is squeezed and discharged through the sewage discharge port. In addition, by setting the water hole, the water mixed in the sediment can be squeezed out, thereby avoiding the secondary treatment of the discharged metal sediment and increasing the practicality of the device.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] One end of the sewage discharge pipe 42 far from the limiting cylinder 421 is fixedly connected with a circular plate 43. A pressure sensor 431 is fixedly installed at the central axis of the side of the circular plate 43 close to the limiting cylinder 421.

[0032] During use, due to the electrolysis operation, metal flocs will be adsorbed on the cathode plate. After the electrolysis reaction has proceeded for a period of time, the cathode plate 13 can be cleaned by controlling the operation of the servo motor 11.

Due to the setting of the length of the elliptical inner toothed disk 15, the surface of the elliptical inner toothed disk 15 can be cleaned in all directions while the pinion 3 moves. As the rotating shaft 2 rotates, the scraper 231 and the vortex blade 24 rotate synchronously. The scraper 231 can drive the sediment deposited on the bottom plate 14 to rotate synchronously. Through the inclined setting of the scraper 231, the sediment will fall into the sewage funnel 4 along the side wall of the scraper 231. Through the setting of the vortex blade 24, the metal sediment can be rolled into the sewage pipe 42 through the connecting tube 41 and squeezed. When the sediment accumulates to a certain extent, it will push the movable block 53 to move, and the trigger rod 54 will trigger the pressure sensor 431, thereby transmitting the signal to the electric motor 5. The electric motor 5 works to drive the screw 51 to rotate, which in turn can make the threaded barrel 52 move toward the side close to the movable block 53, squeeze the sediment, and push the movable block 53 to move synchronously, so that the sediment can be squeezed and discharged through the sewage outlet 44, and through the setting of the water hole 521, the water mixed in the sediment can be squeezed out, avoiding the secondary treatment of the discharged metal sediment, and increasing the practicality of the device. Afterwards, the electric motor 5 rotates in the opposite direction to drive the threaded barrel 52 to reset, the support spring 55 extends, and the movable block 53 resets, so that the sewage outlet 44 is closed, which is convenient for the reuse of the device.
