Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and specifically to a device for adding chemicals for wastewater treatment. Background Technology

[0002] Wastewater treatment requires the addition of appropriate chemical agents. These agents react with organic or inorganic matter in the wastewater to purify it. Most existing wastewater treatment methods involve directly adding granular chemical agents to the wastewater tank, waiting for the agents to react, and then discharging the wastewater into the next treatment stage. This process has several drawbacks: adding the chemical agents to the tank causes them to concentrate in one area, resulting in uneven distribution and insufficient mixing with the wastewater, thus reducing the treatment effectiveness. Therefore, we propose a wastewater treatment agent addition device. Utility Model Content

[0003] The purpose of this invention is to provide a device for adding chemicals for wastewater treatment, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for adding chemicals for wastewater treatment, comprising a mixing tank, a support frame fixedly connected to the bottom of the mixing tank, a feeding tank fixedly mounted on the top of the mixing tank, a feeding mechanism fixedly mounted between the feeding tank and the mixing tank, an inlet pipe fixedly connected to the side wall of the mixing tank, a first switching valve fixedly mounted inside the inlet pipe, a stirring mechanism mounted inside the mixing tank, and one end of an outlet pipe fixedly connected to the bottom of the mixing tank, and a mixing mechanism fixedly connected to the other end of the outlet pipe;

[0005] The mixing mechanism includes a fixed tube, with a dispensing tube fixedly connected to the end of the fixed tube, and a buffer block fixedly assembled inside the dispensing tube.

[0006] Preferably, the feeding mechanism includes a guide platform, which is fixedly installed at the bottom of the inner cavity of the feeding tank. A connecting pipe is fixedly connected to the bottom of the feeding tank and extends into the mixing tank. A flow control valve is fixedly installed inside the connecting pipe.

Stirring frames are uniformly fixedly mounted on the side wall of the rotating shaft. The output end of the drive motor is fixedly connected to the bottom of the rotating shaft. Bottom blocks are uniformly fixedly connected to the bottom of the stirring frames.

[0008] Preferably, the liquid outlet pipe includes a top pipe and a bottom pipe. The top of the top pipe is fixedly connected to the bottom of the mixing tank. A second switching valve is fixedly installed inside the top pipe. The bottom of the top pipe is fixedly connected to the bottom pipe. The bottom of the bottom pipe is fixedly connected to the top of the liquid separator. An assembly frame is fixedly installed in the inner cavity of the bottom pipe.

[0009] Preferably, the top of the buffer block is wavy.

[0010] Compared with the prior art, the beneficial effects of this utility model are: a device for adding chemicals for sewage treatment. This device is mainly used before sewage enters the sewage tank. It adds a slow-release chemical solution to the sewage through the outlet pipe, and the solution enters the sewage tank along with the sewage. Compared with the traditional treatment method of directly adding chemicals to the sewage tank, this device can improve the mixing degree between the chemical agent and the sewage, and make the chemical agent more evenly distributed in the sewage, thereby improving the treatment effect of sewage in the sewage tank.

[0011] This device is equipped with a stirring mechanism. Before the chemical agents are added to the wastewater, the stirring mechanism can fully mix the chemical agents with the water to form a chemical agent solution. Adding the solution to the wastewater can improve the binding degree between the wastewater and the chemical agents, thereby enhancing the treatment effect of the chemical agents on the wastewater. At the same time, this device is equipped with a mixing mechanism, which further improves the mixing degree between the chemical agent solution and the wastewater by diverting the wastewater and using buffer blocks to slow down the flow rate of the wastewater, and improves the uniformity of the chemical agent solution distribution in the wastewater.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a device for adding chemicals for wastewater treatment, including a mixing tank 1. A support frame 2 is fixedly connected to the bottom of the mixing tank 1, supporting and fixing the mixing tank 1. A feeding tank 3 is fixedly mounted on the top of the mixing tank 1. A feeding rack is integrally formed on the top of the feeding tank 3 for adding chemical agents into the feeding tank 3. A feeding mechanism 4 is installed between the feeding tank 3 and the mixing tank 1. The feeding mechanism 4 evenly adds chemical agents for wastewater treatment (such as granular agents such as aluminum sulfate, sodium hydroxide, and calcium hydroxide) into the mixing tank 1. A stirring mechanism 5 is installed inside the mixing tank 1. The side wall of the mixing tank 1 is fixed... A liquid inlet pipe 6 is fixedly connected to the mixing tank 1. The liquid inlet pipe 6 is used to add a solution that is mixed with chemical agents into the mixing tank 1. A first switch valve 7 is fixedly installed inside the liquid inlet pipe 6. The first switch valve 7 is electrically connected to an external power supply and an external controller. The first switch valve 7 is a solenoid valve. The opening and closing of the liquid inlet pipe 6 is controlled by the first switch valve 7. The chemical agents are mixed with water by the stirring mechanism 5, and the chemical agents are slowly released. Then, the solution is transported to the mixing mechanism 9 through the liquid outlet pipe 8 at the bottom. Before the sewage is discharged into the sewage tank, the slowly released solution of the chemical agents is evenly mixed in the sewage, which improves the uniformity of the mixing between the chemical agents and the sewage and improves the treatment effect of the chemical agents on the sewage.

[0020] like Figure 2 and Figure 3As shown, the feeding mechanism 4 includes a guide platform 41, which is fixedly installed inside the feeding tank 3. The guide platform 41 has a discharge port that slopes downwards in the middle. The guide platform 41 guides the material to the bottom of the feeding tank 3. The bottom of the feeding tank 3 is fixedly connected to a connecting pipe 42 that extends into the mixing tank 1. A flow control valve 43 is fixedly installed inside the connecting pipe 42. The flow control valve 43 is electrically connected to an external power supply and an external controller. The feeding amount of the feeding tank 3 can be adjusted by the flow control valve 43. The bottom of the connecting pipe 42 is fixedly connected to a discharge pipe 44 that is symmetrically arranged on the left and right. The bottom of the discharge pipe 44 has discharge holes 45 evenly opened. The material can enter the discharge pipe 44 through the connecting pipe 42 for discharge by the inclined discharge pipe 44. The evenly arranged discharge pipe 44 can keep the material feeding into the mixing tank 1 uniform.

[0021] like Figure 2 As shown, the stirring mechanism 5 includes a drive motor 51, which is fixedly mounted on the bottom of the stirring tank 1. A rotating shaft 52 is rotatably connected to the bottom of the inner cavity of the stirring tank 1. The output end of the drive motor 51 is fixedly connected to the bottom of the rotating shaft 52 through a coupling. The drive motor 51 is electrically connected to an external power source. A stirring frame 53 is uniformly fixedly connected to the side wall of the rotating shaft 52. By driving the stirring frame 53 to rotate, the medicine and solution located in the stirring tank 1 can be fully mixed. A bottom block 54 is uniformly integrally formed on the bottom of the stirring frame 53. The bottom block 54 scrapes the medicine located at the bottom of the stirring tank 1 during the rotation of the stirring frame 53, preventing the medicine from accumulating at the bottom of the stirring tank 1.

[0022] like Figure 4 As shown, the mixing mechanism 9 includes a fixed pipe 91, with a distribution pipe 92 integrally formed at the end of the fixed pipe 91. The fixed pipe 91 and the distribution pipe 92 are distributed in a Y-shape. There are two outlet pipes 8, and the output ends of the two outlet pipes 8 are respectively fixedly connected to the corresponding distribution pipes 92. The sewage entering the fixed pipe 91 is diverted to the distribution pipes 92 on both sides. Buffer blocks 93 are fixedly installed in the two distribution pipes 92. The top of the buffer block 93 is wavy. By setting the buffer block 93, the passage speed of sewage in the distribution pipe 92 can be slowed down. The position of the buffer block 93 corresponds to that of the outlet pipe 8. The slow-release chemical agent solution discharged from the outlet pipe 8 is fully mixed with the sewage that has passed through the buffer block 93. The subsequent sewage is discharged into the sewage tank to enhance the treatment effect of the chemical agent on the sewage.

[0023] like Figure 5As shown, the outlet pipe 8 includes a top pipe 81 and a bottom pipe 82. The top pipe 81 is fixedly connected to the bottom of the mixing tank 1 and communicates with the inner cavity of the mixing tank 1. A second switching valve 83 is fixedly installed inside the top pipe 81. The second switching valve 83 is electrically connected to an external power supply and an external controller. The second switching valve 83 is a liquid flow control valve, and the liquid outlet flow rate of the second switching valve 83 can be controlled by the external controller. The bottom of the bottom pipe 82 extends into the distribution pipe 92. The bottom pipe 82 is used to add a slow-release solution of the chemical agent to the buffer block 93 area of ​​the distribution pipe 92. An assembly is fixedly installed at the bottom of the inner cavity of the bottom pipe 82. The bottom of the frame 85 is detachably fixed with a filter frame 84 by fixing bolts. A filter screen is embedded in the filter frame 84. The filter frame 84 filters the slow-release chemical solution entering the separatory tube 92, preventing undissolved chemical clumps or large impurities from entering the separatory tube 92. The top and bottom of the bottom tube 82 are detachably fixed to the top tube 81 and the separatory tube 92 by fixing bolts. Disassembling the bottom tube 82 facilitates regular cleaning and maintenance of the filter frame 84, ensuring that the filter frame 84 maintains a good filtration effect.

[0024] Working Principle: During use, the inlet end of the fixed pipe 91 of the mixing mechanism 9 is connected to the inlet end of the sewage, and the outlet end of the separating pipe 92 is connected to the inlet of the sewage tank. First, the required amount of chemical agents to be added to the sewage is added to the feeding tank 3 according to the sewage treatment process. Water is then added to the mixing tank 1 according to the proportion of the chemical agents. The flow control valve 43 is opened to control the material in the feeding tank 3 to slowly flow downwards. The discharge pipe 44 can evenly distribute the material downwards. The drive motor 51 drives the rotation of the mixing frame 53, allowing the chemical agents and water to be fully mixed, forming... After the chemical solution is prepared, the wastewater inlet is turned on. The wastewater enters through the fixed pipe 91 and is divided through the separator 92. During the process of the wastewater passing through the separator 92, it is slowed down by the buffer block 93. During the deceleration process, the second switch valve 83 in the outlet pipe 8 opens, and the chemical solution is slowly added to the wastewater through the outlet pipe 8, which mixes thoroughly with the wastewater passing through the buffer block 93 area. This device can increase the uniformity of the mixing between the wastewater treatment chemical agent and the wastewater when the wastewater is discharged into the wastewater tank, avoid the concentrated distribution of the chemical agent in the wastewater tank, and improve the treatment effect of the chemical agent on the wastewater.
