Description

Technical Field

[0001] The utility model relates to the technical field of chemical water treatment tanks in thermal power plants, in particular to a chemical water treatment tank with a protective structure. Background Art

[0002] Thermal power plants, referred to as thermal power plants, are factories that use combustibles as fuel to produce electricity. Thermal power plants need to treat the wastewater generated during operation. Usually, wastewater is treated through chemical water treatment tanks, which remove pollutants in the form of dissolved or colloidal substances in wastewater through electrolytic chemical reactions or convert them into harmless substances. Existing chemical water treatment tanks still have certain defects when used;

[0003] In the prior art, chemical water treatment tanks can sterilize and remove scale from pollutants in sewage by electrolyzing water. Usually, chemical water treatment tanks are controlled and operated by control boxes. During transportation of chemical water treatment tanks, the surface of the control box is easily squeezed and scratched, thus affecting the subsequent use of the control box. Utility Model Content

[0004] The utility model aims to provide a chemical water treatment tank with a protective structure to solve the problem that the control box on the chemical water treatment tank on the market currently has no protective measures as mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chemical water treatment tank with a protective structure, comprising: a tank body, a control box, a discharge pipe, a drain valve and a fixed block, wherein a control box is installed at the front of the tank body, a discharge pipe is welded to the bottom of the tank body, a drain valve is arranged above the discharge pipe, and a fixed block is respectively welded to the top and bottom of the control box, a transparent protective cover is arranged at the front of the control box, a docking block is respectively fixed to the top and bottom of the transparent protective cover, a spring is connected inside the docking block, one end of the spring is connected to a movable plate, a limiting block is fixed to the top of the movable plate, and a sliding rod is connected through the inside of the movable plate.

[0006] Preferably, a sliding connection is formed between the movable plate and the sliding rod.

[0007] Preferably, the limiting blocks are in the shape of a triangle, and two groups of limiting blocks are symmetrically arranged about the center of the transparent protective cover.

[0008] Preferably, a connecting cylinder is fixed to the outer side of the bottom of the sewage valve, and a sealing ring is embedded in the connecting cylinder.

[0009] Preferably, a rubber block is fixed on the outside of the connecting cylinder, and a clamping block is installed on the outside of the rubber block.

[0010] Preferably, a butt-joint pipe is welded above the discharge pipe, a connecting block is welded on the outside of the butt-joint pipe, and a through groove is penetrated through the inside of the connecting block.

[0011] Compared with the prior art, the beneficial effects of the utility model are: the chemical water treatment tank with a protective structure can sterilize and descale the pollutants in the sewage through the cathode and anode electrolysis inside the tank body. Usually the control box is directly installed on the outside of the tank body, which can easily cause the control box to be damaged during transportation. When the transparent protective cover moves, it can drive the docking block to move, and when the docking block moves, it can drive the limit block to move. The sealing ring can improve the sealing performance of the drain valve and the docking pipe, so that when the drain valve on the chemical water treatment tank is abnormal, maintenance work can be quickly carried out.

[0012] 1. The chemical water treatment tank can sterilize and descale pollutants in sewage through cathode and anode electrolysis inside the tank body. Usually, the control box is directly installed on the outside of the tank body, which can easily cause the control box to be damaged during transportation. When the transparent protective cover moves, it can drive the docking block to move, and when the docking block moves, it can drive the limit block to move. When the transparent protective cover moves to the surface of the control box, the inclined surface of the limit block will be squeezed by the fixed block. At this time, the limit block can drive the moving plate to move, and the spring can be squeezed when the moving plate slides. When the limit block moves to the inside of the docking block, the end of the docking block can pass through the fixed block. At this time, the transparent protective cover can protect the surface of the control box, and the limit block can be reset by the spring and popped out from the inside of the docking block. The limit block can make the transparent protective cover stably installed on the front surface of the control box, so that the chemical water treatment tank can protect the surface of the control box through the transparent protective cover during transportation.

[0013] 2. The dirt generated after sewage purification in the chemical water treatment tank can be discharged through the drain valve. Usually, the drain valve is fixed to the discharge pipe by multiple sets of bolts and screws, which is cumbersome to disassemble using tools. For this reason, two sets of blocks can be pressed at the same time. When the blocks are squeezed, the rubber blocks can be deformed. At this time, the drain valve can be pulled, and the connecting tube can be moved when the drain valve moves. When the rubber block slides out of the connecting block through the through groove, the drain valve can be quickly disassembled and maintained. The sealing ring can improve the sealing performance of the drain valve and the butt pipe, which is convenient for quick maintenance when the drain valve on the chemical water treatment tank is abnormal.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 5 The utility model provides a technical solution: a chemical water treatment tank with a protective structure, comprising: a tank body 1, a control box 2, a discharge pipe 3, a drain valve 4 and a fixed block 5, the control box 2 is installed at the front of the tank body 1, the discharge pipe 3 is welded at the bottom of the tank body 1, and the drain valve 4 is arranged above the discharge pipe 3, and the fixed block 5 is respectively welded to the top and the bottom of the control box 2, and a transparent protective cover 6 is arranged at the front of the control box 2, and the top and the bottom of the transparent protective cover 6 are respectively fixed with docking blocks 7, a spring 8 is connected inside the docking block 7, and a moving plate 9 is connected at one end of the spring 8, a limiting block 10 is fixed on the top of the moving plate 9, a sliding rod 11 is connected to the inside of the moving plate 9, and a sliding connection is formed between the moving plate 9 and the sliding rod 11, and the limiting block 10 is in the shape of a triangle, and two groups of limiting blocks 10 are symmetrically arranged about the center of the transparent protective cover 6.

[0022] During specific implementation, the chemical water treatment tank can sterilize and descale pollutants in the sewage through the cathode and anode electrolysis inside the tank body 1. Usually, the control box 2 is directly installed on the outside of the tank body 1, and there are usually no protective measures on the surface, which can easily cause the control box 2 to be damaged during transportation, affecting the later use of the control box 2. For this reason, the transparent protective cover 6 can be pushed to move. When the transparent protective cover 6 moves, it can drive the docking block 7 to move. When the docking block 7 moves, it can drive the limit block 10 to move. When the transparent protective cover 6 moves to the surface of the control box 2, the inclined surface of the limit block 10 will be squeezed by the fixed block 5. At this time, the limit block 10 can drive the moving plate 9 to move. When the moving plate 9 moves, it can slide through the slide rod 11. When the moving plate 9 slides, it can squeeze the spring 8. When the limit block 10 moves to the inside of the docking block 7, the end of the docking block 7 can pass through the fixed block 5. At this time, the transparent protective cover 6 can protect the surface of the control box 2, and the limit block 10 can be reset by the spring 8 and popped out from the inside of the docking block 7. The limit block 10 can stably install the transparent protective cover 6 on the front surface of the control box 2.

[0023] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 It can be seen that the surface of the control box 2 can be protected by the transparent protective cover 6 during transportation of the chemical water treatment tank.

[0024] See also Figure 1 , Figure 2 , Figure 5 It can be seen that a connecting tube 12 is fixed to the outside of the bottom of the sewage valve 4, a sealing ring 13 is embedded in the connecting tube 12, a rubber block 14 is fixed to the outside of the connecting tube 12, a clamping block 15 is installed on the outside of the rubber block 14, a butt tube 16 is welded above the discharge pipe 3, a connecting block 17 is welded to the outside of the butt tube 16, a through groove 18 is opened inside the connecting block 17, and the shape of the clamping block 15 is triangular.

[0025] During specific implementation, the dirt generated after sewage purification in the chemical water treatment tank can be discharged through the drain valve 4. Usually, the drain valve 4 is fixed to the discharge pipe 3 by multiple groups of bolts and screws, which is cumbersome to disassemble using tools. This method is not easy to perform quick maintenance on the drain valve 4. For this reason, the two groups of blocks 15 can be pressed at the same time. When the blocks 15 are squeezed, the rubber blocks 14 can be deformed. At this time, the drain valve 4 can be pulled. When the drain valve 4 moves, the connecting tube 12 can be driven to move. When the connecting tube 12 moves, the rubber block 14 can be driven to move. When the rubber block 14 slides out of the connecting block 17 through the through groove 18, the drain valve 4 can be quickly disassembled and maintained. The sealing ring 13 can improve the sealing performance of the drain valve 4 and the butt pipe 16.

[0026] See also Figure 1 , Figure 2 , Figure 5 It can be seen that when an abnormality occurs in the drain valve 4 on the chemical water treatment tank, maintenance work can be quickly performed.

[0027] To sum up, when using the chemical water treatment tank with a protective structure, electrodes are inserted into the wastewater inside the tank body 1 and current is passed through, and electrons are accepted on the cathode plate. During the electrolysis of water, oxygen is generated on the anode and hydrogen is generated on the cathode. The above-mentioned comprehensive process causes oxidation to occur on the anode and reduction to occur on the cathode, thereby sterilizing and descaling pollutants in the sewage. The electrolysis of water by the chemical water treatment tank is a prior art and will not be described in detail here. The control box 2 in transportation can be protected by the transparent protective cover 6, and maintenance and repair operations can be quickly carried out by quickly disassembling the drain valve 4, saving time. In the utility model, the improvement of the chemical water treatment tank belongs to the structural improvement. Therefore, this improved chemical water treatment tank is not only suitable for thermal power plants, but also can be applied to other similar water conservancy projects using chemical water treatment tanks, and has good versatility. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
