Description

Technical Field

[0001] The utility model relates to wastewater, in particular to an adding device for a heavy metal scavenger for wastewater, belonging to the technical field of heavy metal scavengers for wastewater. Background Technique

[0002] Wastewater refers to the general term for the water discharged during the activities of residents and the runoff rainwater. It includes domestic sewage, industrial wastewater, and other useless water such as the first rain runoff into the drainage pipe channels. Generally, it refers to the water that cannot be recycled after a certain technical treatment or the water whose purification treatment difficulty after primary pollution cannot reach a certain standard;

[0003] The Chinese published patent (publication number: CN 215963558 U) discloses a preparation device for a heavy metal scavenger for wastewater treatment, including an outer tank, a preparation tank, and a control box. The preparation tank is installed inside the outer tank, and a circular groove is opened in the outer tank. An electric heating wire is sleeved in the circular groove outside the preparation tank. A circular ring stopper is installed on the lower end tank body inside the preparation tank. A filter screen is installed on the circular ring stopper in a limiting manner. Two handles are symmetrically installed at both ends of the top of the filter screen. The upper end of the preparation tank is spirally installed with a tank cover. Handles are symmetrically installed on both sides of the tank cover. A motor is installed in the middle of the top of the tank cover. The output shaft of the motor is meshed with a stirring shaft, and stirring paddles are installed on the stirring shaft. Liquid inlet pipe A, a solid feed hopper, and liquid inlet pipe B are respectively installed at the left and right ends of the motor on the top of the tank cover, and a control valve and a flow meter are installed on the liquid inlet pipe A. By heating the liquid medicine and stirring the liquid medicine with a stirring device, the utility model can make the liquid medicine mix quickly, thereby accelerating the crystallization speed.

[0004] When carrying out the crystallization work on the heavy metals in the wastewater with a scavenger, it is necessary to accurately add the scavenger with a matching component according to the amount of heavy metals contained in the wastewater. However, the above device is not equipped with a corresponding adding device. As a result, when the scavenger is poured into the wastewater, the content may be too little or too much. Pouring too much or too little of the scavenger will affect the crystallization effect of the heavy metals in the wastewater, and at the same time, it may cause the heavy metals in the wastewater to not be completely crystallized. Also, during use, the adding device needs to be repaired regularly. When the installation of the adding device is relatively cumbersome, it may take a long time to disassemble. At this time, the machine is often in a stopped working state. The longer the time spent on disassembly and repair, the more time for purifying the wastewater will be wasted, thereby reducing the purification efficiency of the wastewater. Therefore, an adding device for a heavy metal scavenger for wastewater is proposed. Content of the Utility Model

[0005] In view of this, the utility model provides an adding device for a heavy metal scavenger for wastewater to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0024] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0026] As Figures 1-4 shown, the embodiment of the present utility model provides a tank body 1. A mounting opening 7 is fixedly installed at the top of the tank body 1.

[0027] By providing the installation mechanism 2, the whole adding mechanism 3 can be fixed, avoiding the cumbersome installation and disassembly and the long time spent, which will delay the capture of heavy metals in the wastewater and reduce the purification efficiency of the wastewater. By providing the adding mechanism 3, a capture agent can be infused into the wastewater and the heavy metals in the wastewater can be crystallized, so as to achieve the purification effect of the wastewater.

[0028] Embodiment 2

[0029] In one embodiment, a gear 202 is fixedly connected to the output end of the first motor 201. A gear ring 203 is movably connected to the outside of the mounting opening 7. The right side of the gear ring 203 meshes with the left side of the gear 202. Moving grooves 204 are formed in the top of the gear ring 203. A mounting rod 205 is movably connected to the inner cavity of the moving groove 204. A fixing plate 206 is fixedly installed on the inner side of the mounting rod 205. The inner side of the fixing plate 206 is in contact with the outer surface of the box body 301. A limiting piece 208 is fixedly installed at one end of the mounting rod 205 away from the fixing plate 206. The top of the limiting piece 208 is in contact with the top of the gear ring 203. A limiting groove 209 is formed in the top of the tank body 1. Limiting rods 210 are fixedly installed on the left and right sides of the bottom of the gear ring 203. The bottom of the limiting rods 210 is slidably connected to the inner cavity of the limiting groove 209. Mounting plates 207 are fixedly installed on the top of the tank body 1. The outer surface of the mounting rod 205 is movably connected to the inner surface of the mounting plate 207.

[0030] By providing the first motor 201, the whole adding mechanism 3 can be quickly fixed or disassembled, reducing the time consumed during installation or disassembly. By providing the limiting piece 208, the position of the mounting rod 205 in the inner cavity of the moving groove 204 can be limited to prevent it from sliding off the bottom of the inner cavity of the moving groove 204. By providing the limiting rods 210 and the limiting groove 209, the gear ring 203 can be limited to prevent it from shifting during rotation, thus avoiding the situation where the fixing plate 206 cannot fix the box body 301. By providing the mounting plate 207, the movement of the mounting rod 205 can be limited to prevent it from shifting during movement, thus avoiding the situation where the fixing plate 206 cannot fix the box body 301.

[0031] Embodiment 3

[0032] In one embodiment, the box body 301 is arranged in the inner cavity of the mounting opening 7. A second motor 302 is fixedly installed on the top of the box body 301. A liquid inlet valve 303 is fixedly installed on the front side of the top of the box body 301. The output end of the second motor 302 is fixedly connected to a hollow tube 304. Liquid inlet grooves 305 are formed on the left and right sides of the top of the outer surface of the hollow tube 304. Stirring blades 306 are fixedly installed on the outer surface of the hollow tube 304. A capture agent control nozzle 307 is fixedly installed at the bottom of the hollow tube 304. A capture agent control panel 308 is fixedly installed on the left side of the top of the box body 301.

[0033] By setting the box body 301, the stirring blade 306 can be rotated to increase the speed of fusion of the capture agent and the wastewater, and accelerate the crystallization speed of the heavy metals in the wastewater. By setting the capture agent control nozzle 307 and the capture agent control panel 308, the discharge amount of the capture agent can be controlled to avoid excessive or insufficient discharge, which does not match the content of heavy metals in the wastewater, and then causes the inability to crystallize the heavy metals.

[0034] When the utility model is working, wastewater is injected into the inner cavity of the tank body 1 through the water inlet 5, and then the capture agent is injected into the inner cavity of the box body 301 from the liquid inlet valve 303, and the capture agent flows into the inner cavity of the hollow tube 304 through the liquid inlet tank 305. At this time, the capture agent control nozzle 307 and the capture agent control panel 308 cooperate to inject the required amount of capture agent into the inner cavity of the tank body 1, and the output end of the second motor 302 drives the hollow tube 304 to rotate, and then the stirring blade 306 rotates to accelerate the capture agent and wastewater. The fusion allows the heavy metals in the wastewater to be crystallized, and then the wastewater and the crystals are discharged through the drain port 6 to complete the addition of the capture agent. When the adding mechanism 3 as a whole needs to be repaired, the output end of the first motor 201 drives the gear 202 to rotate, and through the cooperation of the gear ring 203, the mounting rod 205 moves outward along the inner cavity of the moving groove 204, so that the fixing plate 206 is separated from the outer surface of the box body 301, and then the adding mechanism 3 is taken out upward as a whole to complete the disassembly of the adding mechanism 3 as a whole.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
