Description

Technical Field

[0001] This application relates to the field of wastewater treatment equipment, and more specifically, to a chemical dosing device for a reaction tank in rural wastewater treatment. Background Technology

[0002] With social development, people are becoming increasingly aware of environmental protection, especially the conservation and utilization of various resources. Currently, the rational use of water resources can alleviate water waste. When treating sewage, it is necessary to first add chemicals for sedimentation. In simple rural sewage treatment equipment, during the sedimentation process in the sewage tank, a dosing device, as disclosed in Chinese patent application number 202420949467.X, can continuously change the dosing point of the agent, thereby increasing the contact range between the agent and the sewage and improving the uniformity of agent dosing. However, the dosing tank in this scheme can only move in a straight line, resulting in poor mixing effect between the agent and the sewage. Utility Model Content

[0003] To overcome the shortcomings of the existing system, this application provides a dosing device for a reaction tank in rural sewage treatment, which can solve the problem that the dosing tank can only move in a straight line, resulting in poor mixing effect between the agent and the sewage.

[0004] The technical solution adopted by the embodiments of this application to solve its technical problem is: a chemical dosing device for a reaction tank for rural sewage treatment, including a sewage treatment component and a chemical dosing component.

[0005] A wastewater treatment assembly includes a wastewater treatment tank, the bottom of which is provided with a drain pipe; The dosing assembly includes a mounting plate disposed on the top of the wastewater treatment tank. A motor is installed on the wastewater treatment tank. The drive end of the motor movably passes through the mounting plate and is detachably connected to a feeding bucket. The side wall of the feeding bucket is provided with fine mesh holes, and the feeding bucket is located inside the wastewater treatment tank.

[0006] In one specific implementation, the drive end of the motor is fixedly connected to a connector, and the connector is detachably connected to the feeding hopper.

Detailed Implementation

[0017] The technical solution in this application embodiment is to solve the problem that the dosing tank can only move in a straight line, resulting in poor mixing effect between the agent and the sewage. The overall idea is as follows: Please see Figures 1-5 A chemical dosing device for a reaction tank in rural sewage treatment includes a sewage treatment component 10 and a chemical dosing component 20.

[0018] Please see Figure 1 and Figure 2 The sewage treatment component 10 includes a sewage treatment tank 110, and a drain pipe 120 is provided at the bottom of the sewage treatment tank 110; sewage enters the sewage treatment tank 110 for sedimentation, thereby achieving preliminary treatment and sedimentation of rural sewage.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The dosing assembly 20 includes a mounting plate 210, which is positioned on top of the wastewater treatment tank 110. A motor 220 is mounted on the wastewater treatment tank 110. The drive end of the motor 220 movably passes through the mounting plate 210 and is detachably connected to a feeding bucket 230. The side wall of the feeding bucket 230 has fine mesh openings, and the feeding bucket 230 is located inside the wastewater treatment tank 110. The chemical is placed into the feeding bucket 230, and then the motor 220 is started, causing the feeding bucket 230 to rotate. This allows the chemical inside to flow out through the fine mesh openings while rotating. The rotation of the feeding bucket 230 by the motor 220, causing the chemical to rotate and flow out simultaneously, achieves mixing between the chemical and the wastewater. The rotation of the feeding bucket 230 also agitates the wastewater, thus improving the mixing efficiency of the chemical and wastewater and enhancing the flocculation effect of the wastewater. The detachable connection between the feeding hopper 230 and the motor 220 allows the feeding hopper 230 to be disassembled. When the feeding hopper 230 becomes clogged after prolonged use, it can be disassembled for cleaning, thereby improving the efficiency of the drug flow.

[0020] A connector 240 is fixedly connected to the drive end of the motor 220, and the connector 240 is detachably connected to the feeding bin 230. The connector 240 includes a connecting plate 241 and two L-shaped limiting plates 242. The connecting plate 241 is fixedly connected to the output end of the motor 220. One L-shaped limiting plate 242 is fixedly connected to one end of the connecting plate 241, and the other L-shaped limiting plate 242 is elastically connected to the other end of the connecting plate 241. The two L-shaped limiting plates 242 are detachably inserted into the side walls of the feeding bin 230. A mounting groove is provided inside one end of the connecting plate 241, and a spring 260 is provided inside the mounting groove. One L-shaped limiting plate 242 is connected to the spring 260. Slots 231 that mate with the two L-shaped limiting plates 242 are respectively provided on the outer side of the feeding bin 230. During disassembly, pulling one L-shaped limiting plate 242 exposes it from the slot 231, and then lifting it upwards dislodges the other L-shaped limiting plate 242 from the other slot 231. During installation, first insert one L-shaped limiting plate 242 into the slot 231, then pull the other L-shaped limiting plate 242 into the other slot 231. At this point, the spring 260 ensures the L-shaped limiting plate 242 is firmly inserted into the slot 231, thus achieving installation. The spring 260 and L-shaped limiting plates 242 make installing and disassembling the feeding hopper 230 simpler and faster, improving the efficiency of installation and disassembly.

[0021] A stirring rod 250 is installed on the outside of the feeding tank 230. When the feeding tank 230 rotates, the stirring rod 250 also rotates, thereby agitating the wastewater.

[0022] Please refer to 1. The dosing device for the reaction tank in rural sewage treatment also includes a lifting assembly 30. The lifting assembly 30 includes two multi-stage cylinders 320, which are respectively installed on both sides of the sewage treatment tank 110. The two ends of the mounting plate 210 are fixedly connected to the cylinder rod ends of the two multi-stage cylinders 320. Mounting blocks 310 are fixedly connected to both sides of the sewage treatment tank 110, and the multi-stage cylinders 320 are mounted on the mounting blocks 310. The two multi-stage cylinders 320 can lift and lower the dosing tank 230, so that after the sewage is stirred, the dosing tank 230 can be raised from the sewage treatment tank 110, preventing it from contacting the sewage. This reduces the rusting efficiency of the dosing tank 230 and increases its service life.

[0023] When this application is used: The reagent is placed into the feeding tank 230, and then the motor 220 is started, causing the feeding tank 230 to rotate. This allows the reagent inside to flow out through the fine mesh while rotating. The motor 220 drives the feeding tank 230 to rotate, causing the reagent to flow out while rotating, thus achieving mixing between the reagent and the wastewater. The rotation of the feeding tank 230 also agitates the wastewater, improving the mixing efficiency and thus enhancing the flocculation effect. The detachable connection between the feeding tank 230 and the motor 220 allows the feeding tank 230 to be disassembled. If the feeding tank 230 becomes clogged after prolonged use, it can be disassembled for cleaning, improving the reagent flow.

[0024] In summary, this application uses a motor 220 to drive the feeding tank 230 to rotate, so that the agent flows out while rotating, thereby achieving mixing of the agent and the wastewater. Furthermore, the rotation of the feeding tank 230 can agitate the wastewater, thus achieving mixing of the agent and wastewater at the same time, improving the mixing efficiency of the agent and wastewater, and thereby improving the flocculation effect of the wastewater.

[0025] It should be noted that the specific model specifications of the motor 220 and the multi-stage cylinder 320 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0026] The power supply and operating principle of the motor 220 and the multi-stage cylinder 320 are clear to those skilled in the art and will not be described in detail here.

[0027] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
