Description

Technical Field

[0001] This utility model relates to the technical field of multi-stage sedimentation sludge tanks, specifically a multi-stage sedimentation sludge tank for electrochemical descaling equipment. Background Technology

[0002] Electrochemical descaling equipment for circulating water refers to a method that uses the mechanism of electrolysis to transform impurities in circulating water into harmless solid substances through a series of chemical reactions at the cathode and anode, thereby purifying the water. This method can effectively remove pollutants such as hardness, suspended solids, colloids, bacteria, and algae from water without the addition of chemical agents, significantly reducing sewage discharge and making it environmentally friendly. Through electrical control, the equipment can achieve periodic automatic scaling and descaling, realizing automated production, reducing labor intensity and costs, and saving energy and increasing efficiency for enterprises. Circulating water is introduced into the electrolytic cell through the inlet. The electrolytic cell is equipped with cathode and anode plates. During electrolysis, the water flowing between the cathode and anode plates generates strong oxidizing substances such as OH, O3, H2, O2, and HClO at the anode, which play a role in sterilization, algae removal, and corrosion prevention. Calcium and magnesium ions precipitate from the water, forming scale deposits such as calcium carbonate, magnesium carbonate, and magnesium hydroxide, along with some slime, which are adsorbed onto the cathode plate in solid particle form. A transmission mechanism drives the cathode plate up and down, and a scraper mechanism within the electrolytic cell scrapes off the adsorbed calcium carbonate, magnesium carbonate, and magnesium hydroxide, discharging the wastewater and scale into a sedimentation tank at the bottom of the electrolytic cell for further deposition. Traditional sedimentation tanks are single-box type. When wastewater and scale fall into the sedimentation tank, the scale, being denser than water, slowly settles at the bottom, while the supernatant flows back to the water tower. Because the scale deposition process is slow, some scale often flows back to the water tower with the supernatant before it has fully settled, causing secondary pollution. This is detrimental to the entire pipe network, indirectly increasing energy consumption and reducing the descaling efficiency of the electrochemical descaling equipment. Furthermore, the water level in the sedimentation tank is difficult to control. Utility Model Content

[0003] The purpose of this invention is to provide a multi-stage sedimentation tank for electrochemical descaling equipment. This solves the problem of traditional single-box sedimentation tanks, where, after wastewater and scale fall into the tank, the scale, being denser than water, slowly settles at the bottom, while the supernatant flows back to the water tower. Because the scale deposition process is slow, a small portion often flows back to the water tower with the supernatant before it has fully settled, causing secondary pollution and negatively impacting the entire pipe network. This indirectly increases energy consumption, reduces the descaling efficiency of the electrochemical descaling equipment, and makes it difficult to control the water level in the sedimentation tank.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage sedimentation tank for electrochemical descaling equipment, comprising a primary sedimentation tank, a connecting pipe fixedly connected inside the primary sedimentation tank, a valve provided in the middle of the connecting pipe, a secondary sedimentation tank connected to the outside of the connecting pipe, a tertiary sedimentation tank provided at the end of the secondary sedimentation tank, an overflow weir provided between the secondary and tertiary sedimentation tanks, a gravity flow port fixedly connected to the side wall of the tertiary sedimentation tank, and an adjustment mechanism provided on the overflow weir.

[0005] Preferably, the secondary sedimentation tank and the primary sedimentation tank are fixedly connected, and the tertiary sedimentation tank and the primary sedimentation tank are fixedly connected. By setting up three sedimentation tanks, the sedimentation time of scale is extended, resulting in more thorough sedimentation.

[0006] Preferably, the adjusting mechanism includes a lifting plate, a support plate fixedly connected to the surface of the lifting plate, a housing fixedly installed on the surface of the overflow weir, a motor fixedly installed on the surface of the housing, a screw fixedly connected to the upper end of the motor shaft, a screw cylinder threadedly connected to the outer side of the screw, the screw cylinder and the housing being slidably connected, a slide cylinder slidably connected to the outer side of the screw cylinder, the slide cylinder and the support plate being fixedly connected, and a spring being installed inside the slide cylinder. The motor drives the screw to rotate and the screw cylinder to perform threaded movement, thereby causing the screw cylinder to compress the spring, which in turn causes the support plate to move the lifting plate within the secondary sedimentation tank, thus changing the distance between the upper end of the lifting plate and the bottom of the sedimentation tank, thereby allowing adjustment of the water level in the sedimentation tank.

[0007] Preferably, the lifting plate and the overflow weir are slidably connected, and the lifting plate and the secondary sedimentation tank are slidably connected. The water level is controlled by installing the lifting plate.

[0008] Preferably, a sliding pin is fixedly connected to the surface of the screw cylinder, and the sliding pin and the slide cylinder are slidably connected. By providing the sliding pin, relative rotation between the screw cylinder and the slide cylinder is prevented.

[0009] Preferably, one end of the spring is fixedly connected to the support plate, and the other end of the spring is fixedly connected to the screw cylinder. The spring provides elastic support to the support plate.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model forms a multi-stage sedimentation tank by setting up a primary sedimentation tank, a secondary sedimentation tank and a tertiary sedimentation tank. Through the optimized design of the two box-type water tanks, a three-stage sedimentation effect is achieved, so that the sewage and scale discharged from the electrolytic cell flow through the three sedimentation tanks in sequence, which prolongs the sedimentation time of the scale and makes the sedimentation more complete.

[0012] 2. This utility model uses a motor to drive the screw to rotate and the screw barrel to make a spiral motion, which in turn causes the screw barrel to compress the spring, which in turn causes the support plate to slide the lifting plate in the secondary sedimentation tank, thereby changing the distance between the upper end of the lifting plate and the bottom of the sedimentation tank, and thus allowing the water level in the sedimentation tank to be adjusted.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 A multi-stage sedimentation tank for electrochemical descaling equipment includes a primary sedimentation tank 1, with a connecting pipe 2 fixedly connected inside the primary sedimentation tank 1. A valve 3 is installed in the middle of the connecting pipe 2, and a secondary sedimentation tank 4 is connected to the outside of the connecting pipe 2. A tertiary sedimentation tank 6 is installed at the end of the secondary sedimentation tank 4, and an overflow weir 5 is installed between the secondary sedimentation tank 4 and the tertiary sedimentation tank 6. The secondary sedimentation tank 4 and the primary sedimentation tank 1 are fixedly connected, and the tertiary sedimentation tank 6 and the primary sedimentation tank 1 are fixedly connected. By setting up three sedimentation tanks, the sedimentation time of scale is extended, and the sedimentation is more complete. A gravity flow port 7 is fixedly connected to the side wall of the tertiary sedimentation tank 6, and an adjustment mechanism 8 is installed on the overflow weir 5.

[0018] Please see Figures 1-2The regulating mechanism 8 includes a lifting plate 81, which is slidably connected to the overflow weir 5 and the secondary sedimentation tank 4. The water level is controlled by the lifting plate 81. A support plate 82 is fixedly connected to the surface of the lifting plate 81. A housing 83 is fixedly installed on the surface of the overflow weir 5. A motor 84 is fixedly installed on the surface of the housing 83. A screw 85 is fixedly connected to the upper end of the shaft of the motor 84. A screw cylinder 86 is threadedly connected to the outer side of the screw 85. The screw cylinder 86 is slidably connected to the housing 83. A sliding pin 88 is fixedly connected to the surface of the screw cylinder 86. The sliding pin 88 is slidably connected to the sliding cylinder 87. By setting the sliding pin 88, the screw cylinder 86 and the sliding cylinder 87 are prevented from sliding together. The screw 86 rotates relative to the support plate 82. The outer side of the screw 86 is slidably connected to the slide 87. The slide 87 is fixedly connected to the support plate 82. The inside of the slide 87 is provided with a spring 89. One end of the spring 89 is fixedly connected to the support plate 82, and the other end of the spring 89 is fixedly connected to the screw 86. By setting the spring 89, the support plate 82 is elastically supported. The screw 85 is driven to rotate by the motor 84 and the screw 86 makes a threaded movement, which causes the screw 86 to compress the spring 89. This causes the support plate 82 to drive the lifting plate 81 to slide in the secondary sedimentation tank 4, which causes the distance between the upper end of the lifting plate 81 and the bottom of the sedimentation tank to change, thereby allowing the water level in the sedimentation tank to be adjusted.

[0019] The specific implementation process of this utility model is as follows: In use, according to the water level adjustment device in the sedimentation tank, the motor 84 is started. The motor 84 drives the screw 85 to rotate. The rotation of the screw 85 and the screw barrel 86 perform a threaded motion, thereby causing the screw barrel 86 to move. The screw barrel 86 drives the spring 89 to move upward, the spring 89 drives the support plate 82 to move upward, and the support plate 82 drives the lifting plate 81 to move upward. The upward movement of the lifting plate 81 changes the distance between the upper end of the lifting plate 81 and the secondary sedimentation tank 4. The motor 84 drives the screw 85 to rotate and the screw barrel 86 to perform a threaded motion, thereby... The screw 86 compresses the spring 89, which in turn causes the support plate 82 to drive the lifting plate 81 to slide within the secondary sedimentation tank 4. This causes the distance between the upper end of the lifting plate 81 and the bottom of the sedimentation tank to change, thereby allowing the water level in the sedimentation tank to be adjusted. By setting up a primary sedimentation tank 1, a secondary sedimentation tank 4, and a tertiary sedimentation tank 6, a multi-stage sedimentation tank is formed. Through the optimized design of the two box-type water tanks, a three-stage sedimentation effect is achieved, allowing the wastewater and scale discharged from the electrolytic cell to flow through the three sedimentation tanks in sequence, extending the sedimentation time of the scale and making the sedimentation more complete.
