Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wastewater treatment, specifically to an activated carbon adsorption tank for chemical wastewater. Background Technology
[0002] Chemical wastewater treatment refers to the proper treatment of water used in chemical production processes for reuse in production or proper discharge from the factory. This includes the management of production water and measures taken to facilitate wastewater treatment. The first step in production treatment is to remove insoluble and sedimentary waste from industrial wastewater, and currently, most of these methods involve adsorption tanks for impurity adsorption. Currently, adsorption tanks typically use activated carbon and ion exchange resins as adsorbent particles to adsorb impurities from wastewater. The adsorbent particles are placed in the tank, and as water flows through them, impurities are adsorbed onto the particle surface, while the water falls and is collected through the gaps in the particles. While this method can remove some impurities from wastewater, the adsorbent particles aggregate, making it difficult for their surface to contact the wastewater, thus limiting their effectiveness. Furthermore, after adsorption, flocculants are added to the wastewater for further impurity removal. Typically, the flocculant is added to the tank through a chemical valve, resulting in a concentrated flocculant concentration that affects the mixing efficiency between the flocculant and wastewater. Moreover, replacing the adsorbent particles after they become saturated with impurities is cumbersome, further reducing efficiency. Therefore, we provide an activated carbon adsorption tank for chemical wastewater to address these issues. Utility Model Content
[0003] To address the aforementioned problems, specifically those raised in the background section, this utility model proposes an activated carbon adsorption tank for chemical wastewater, comprising a tank body, a filter plate 1 fixedly disposed above the inner cavity of the tank body, and a filter plate 2 disposed at the tank opening. A drain valve is disposed at the bottom of the side wall of the tank body, and a motor and a reducer are installed at the bottom of the outer wall of the tank body. The output end of the motor is fixedly connected to the input end of the reducer, and a rotating shaft is fixedly disposed at the output end of the reducer. The rotating shaft is rotatably connected to the tank body and the filter plate 1, and several rods are disposed at the top end of the rotating shaft.
[0004] Preferably, a chemical valve is provided on the side wall of the tank below the filter plate, and an annular tube is provided at one end of the chemical valve in the inner cavity of the tank. Several nozzles are provided at the bottom of the annular tube, and multiple sets of stirring rods are provided on the outer wall of the rotating shaft below the nozzles.
[0005] Preferably, a liquid level sensor is installed on the inner wall of the tank below the nozzle, and a fixing bracket corresponding to the agent valve is fixedly installed on the inner wall of the tank, and the fixing bracket is fixedly connected to the annular tube.
[0006] Preferably, the tank body is threadedly connected to a top cover at the tank opening, and a water injection pipe is connected to the top of the top cover. The inner cavity of the tank opening is provided with a placement groove for placing the second filter plate, and a pressure ring is fixedly installed inside the top cover to press and fix the second filter plate.
[0007] Preferably, the filter plate 2 is internally rotatably provided with a connecting shaft, the bottom end of the connecting shaft is provided with a spline groove, the top end of the rotating shaft is keyed to the spline groove, and the plurality of rods are all fixed to the outer wall of the connecting shaft.
[0008] The beneficial technical effects of this utility model are as follows: by setting several rods between filter plate two and filter plate one, and driven by a motor, the internal adsorbed particles are dispersed, so that the adsorbed particles can be exposed, thereby further absorbing impurities in the wastewater.
[0009] By adding a ring pipe to one end of the agent valve, and with the action of the nozzle, the impurity removal agent can be evenly distributed inside the wastewater. Under the mixing of the stirring rod, the impurity removal agent can fully contact the remaining impurities in the wastewater, thus accelerating the mixing speed of the impurity removal agent and the wastewater.
[0010] By setting a threaded top cover at the tank opening, and with the action of the fixing groove and the pressure ring, the filter plate can be quickly disassembled and assembled. At the same time, the rod can be easily disassembled by using the key connection between the connecting shaft and the rotating shaft. This disassembly method makes it easier to replace the adsorbed particles inside. Attached Figure Description

[0014] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0015] This utility model proposes an activated carbon adsorption tank for chemical wastewater, including a tank body 1. A filter plate 2 is fixedly installed on the upper part of the inner cavity of the tank body 1, and a second filter plate 3 is installed at the opening of the tank body 1. A drain valve 4 is installed at the bottom of the side wall of the tank body 1. A motor 5 and a reducer 6 are installed at the bottom of the outer wall of the tank body 1. The output end of the motor 5 is fixedly connected to the input end of the reducer 6. A rotating shaft 7 is fixedly installed at the output end of the reducer 6. The rotating shaft 7 is rotatably connected to the tank body 1 and the first filter plate 2. Several rods 8 are provided at the top of the rotating shaft 7. By setting several rods 8 between the second filter plate 3 and the first filter plate 2, and driven by the motor 5, the adsorbed particles inside are dispersed, so that the adsorbed particles can be exposed, thereby further absorbing impurities in the wastewater. It should be noted that the cross-section of the rods 8 is set as triangular to facilitate better dispersion of the adsorbed particles.
[0016] Specifically, a chemical valve 9 is installed on the side wall of the tank 1 below the filter plate 2. An annular tube 10 is installed at one end of the chemical valve 9 inside the tank 1. Several nozzles 11 are installed at the bottom of the annular tube 10. Multiple sets of stirring rods 12 are installed on the outer wall of the rotating shaft 7 below the nozzles 11. A liquid level sensor 13 is installed on the inner wall of the tank 1 below the nozzles 11. A fixing bracket 14 corresponding to the chemical valve 9 is fixedly installed on the inner wall of the tank 1. The fixing bracket 14 is fixedly connected to the annular tube 10. By adding an annular tube 10 at one end of the chemical valve 9, and under the action of the nozzles 11, the impurity removal agent can be evenly distributed inside the wastewater. Under the mixing of the stirring rods 12, the impurity removal agent can fully contact the remaining impurities in the wastewater, which accelerates the mixing speed of the impurity removal agent and the wastewater. It should be noted that the several nozzles 11 are equidistantly distributed.
[0017] Specifically, a top cover 15 is threadedly connected to the opening of tank body 1, and a water injection pipe 16 is connected to the top of the top cover 15. The inner cavity of the opening of tank body 1 has a groove for placing filter plates 3. A pressure ring 17 is fixedly installed inside the top cover 15 to secure the filter plates 3. A connecting shaft 18 is rotatably installed inside the filter plates 3. A spline groove is opened at the bottom of the connecting shaft 18, and the top of the rotating shaft 7 is keyed to the spline groove. Several rods 8 are fixed to the outer wall of the connecting shaft 18. The water injection pipe 16 is connected to the tank body 1 via... A threaded top cover 15 is provided at the can opening, and the filter plate 3 can be quickly disassembled and assembled under the action of the fixing groove and the pressure ring 17. At the same time, the rod body 8 can be easily disassembled by using the key connection between the connecting shaft 18 and the rotating shaft 7. This disassembly method makes it easier to replace the adsorbent particles inside. It should be noted that the connecting shaft 18 and the filter plate 3 are connected by a bearing, and the bearing and the connecting shaft 18 are connected by a key. This design makes it easy to install the connecting shaft 18 before filling with adsorbent particles.
[0018] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.
[0019] Working principle: When removing impurities from wastewater, the water inlet pipe 16 can be connected to an external wastewater pipe, allowing the wastewater to be discharged into the interior of the top cover 15. Impurities in the wastewater are adsorbed by the adsorption particles between filter plate 2 (3) and filter plate 3 (2). When the adsorption particles are relatively saturated, the motor 5 can be started to drive the reducer 6 to reduce the output speed. The reducer 6, through the rotating shaft 7 and connecting shaft 18, drives the rod 8 to rotate. The rotation of the rod 8 disperses the adsorption particles, exposing the adhered parts of the adsorption particles, thus increasing the adsorption capacity to a certain extent. The adsorption rate is measured, and then the water level in the inner cavity of tank 1 is monitored by the liquid level sensor 13. When the water level reaches a certain value, water injection into tank 1 is stopped. At the same time, the impurity removal agent (i.e., flocculant) is injected into the agent valve 9 using a delivery pump. After the impurity removal agent enters the annular pipe 10, it is evenly sprayed onto the surface of the wastewater using the nozzle 11. Under the action of the motor 5, the rotating shaft 7 drives the stirring rod 12 to rotate, so that the wastewater and impurity removal agent can be fully mixed. After mixing, the water and impurity removal agent can be discharged into the collection tank for sedimentation treatment through the drain valve 4. When it is necessary to replace the adsorbent particles, the top cover 15 can be loosened to remove the filter plate 3. At the same time, the connecting shaft 18 and the rod body 8 are also disassembled. Then, the adsorbent particles can be taken out from the top of tank 1 and replaced.
