Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology, and in particular relates to a dosing device for water treatment. Background Technology

[0002] The chemical dosing step in water treatment is one of the key steps to ensure water quality meets standards. By scientifically and rationally adding chemical agents, suspended solids, colloids, organic matter, microorganisms, and other pollutants in water can be effectively removed, while simultaneously adjusting water pH, hardness, and other indicators to meet the water quality requirements for different applications. Commonly used agents include coagulants, flocculants, and disinfectants; industrial water treatment may require the addition of specialized chemicals such as corrosion inhibitors, scale inhibitors, and bactericides, depending on the specific process requirements.

[0003] Comparing with Chinese Patent CN218307446U, a dosing device for urban sewage treatment is disclosed, including a dosing tank, a base, an inlet, an outlet, a dispersing mechanism, and a lifting mechanism. The dosing tank has a base at its bottom, an inlet connected to one side, an outlet connected to the other side, and a feed inlet connected to one side of its top. Blades are fixed to both sides of the feed inlet. First grooves are formed on both sides of the dosing tank, and second grooves are formed on both sides of the base. The dispersing mechanism runs through the dosing tank, and the lifting mechanism is located within the base. The dispersing mechanism disperses the chemicals after the chemical bag is placed in the feed inlet. Combined with the vibration of the filter screen and spring, the dispersed chemicals fall to the bottom of the dosing tank for more thorough mixing with the sewage. The lifting mechanism adjusts the height of the dosing tank, allowing the inlet and outlet to accommodate different docking heights.

[0004] However, the aforementioned patent requires external energy input and uses a motor to drive the dosing, which increases energy consumption and cannot automatically and dynamically adjust to changes in water flow, seriously affecting the effectiveness of water treatment dosing. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a dosing device for water treatment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A water treatment dosing device includes a chassis for guiding the flow of water to mix chemical powder, and a storage device installed on the chassis for storing the chemical powder and allowing it to fall freely. The bottom end of the storage device is sealed and threadedly connected to the top surface of the chassis. A follower device for controlling the amount of chemical powder added in response to changes in water flow is rotatably installed in the middle of the chassis. The storage device includes a storage cylinder with a guide cone at the bottom and a discharge pipe at the bottom end of the guide cone. A dustproof component is installed at the top end of the storage cylinder. The follower device includes a central rotating shaft with a force-bearing component installed at the bottom end. Spiral pusher blades are evenly distributed on the central rotating shaft, and an agitator for breaking up chemical powder bridging is installed at the top end of the central rotating shaft.

[0008] Furthermore: the chassis device includes a chassis body, which is rectangular, with an inlet pipe and an outlet pipe respectively arranged at the diagonal, a fixing frame is arranged inside the chassis body, and a chassis cover is installed on the front of the chassis body.

[0009] Furthermore: the chassis is rectangular, the water inlet pipe and the water outlet pipe are respectively located at opposite ends of the diagonal, and a sealing gasket is affixed to the inner surface of the chassis cover.

[0010] Furthermore: the dustproof component includes a dustproof cover, and the top surface of the dustproof cover is provided with a handle.

[0011] Furthermore: the dust cover is made of polypropylene material, and the handle and the dust cover are welded together.

[0012] Furthermore: the force-bearing component includes a first connecting sleeve, on which a plurality of force-bearing plates are evenly distributed around the circumference; the stirring component includes a second connecting sleeve, on which a plurality of stirring rods are evenly distributed around the circumference.

[0013] Furthermore: the force-bearing plate is rectangular, and the stirring rod is cylindrical.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. Pure mechanical transmission requires no external power and utilizes the kinetic energy of water flow to achieve automatic operation; the water flow-driven follow-up device (force plate + central rotating shaft) realizes automatic matching of chemical dosage and water flow, avoiding manual adjustment errors; the spiral pusher blade rotates synchronously with the water flow speed to ensure dynamic adaptation of the chemical dosage to the sewage treatment needs.

[0016] 2. The stirring rod assembly effectively breaks up the "bridging" phenomenon of the powder, and the guide cone structure promotes powder flow; the spiral pusher blade forced feeding mechanism overcomes the problem of easy agglomeration in traditional gravity feeding.

[0017] 3. The rectangular box has inlet and outlet water pipes arranged diagonally to extend the water flow path and improve the mixing effect; the integrated structure (storage + mixing + transmission) saves installation space. Attached Figure Description

[0025] Please see Figures 1-5 A water treatment dosing device includes a housing for guiding the flow of water to mix chemical powder, and a storage device installed on the housing for storing the chemical powder and allowing it to fall freely. The bottom end of the storage device is sealed and threadedly connected to the top surface of the housing. A follow-up device is rotatably installed in the middle of the housing for controlling the amount of chemical powder added in accordance with changes in water flow.

[0026] In this embodiment: the chassis device includes a chassis body 101, which is rectangular. An inlet pipe 102 and an outlet pipe 103 are respectively arranged at opposite diagonals. A fixing frame 104 is installed inside the chassis body 101, and a chassis cover 105 is installed on the front of the chassis body 101. The chassis body 101 is rectangular, with the inlet pipe 102 and outlet pipe 103 respectively located at opposite ends of the diagonals. A sealing gasket 106 is pasted on the inner surface of the chassis cover 105. The chassis cover 105 is fixedly connected to the chassis body 101, and the sealing gasket 106 ensures a seal on the contact surface. Wastewater flows into the chassis body 101 from the inlet pipe 102, pushing the force plate 304 to rotate, and then flows out from the outlet pipe 103.

[0027] In this embodiment: the storage device includes a storage cylinder 201, a guide cone 202 is provided at the bottom of the storage cylinder 201, a discharge pipe 203 is provided at the bottom end of the guide cone 202, and a dustproof component is provided at the top of the storage cylinder 201; the dustproof component includes a dustproof cover 204, and a handle 205 is provided on the top surface of the dustproof cover 204; the dustproof cover 204 is made of polypropylene material, and the handle 205 and the dustproof cover 204 are welded together; the powder is poured into the storage cylinder 201, and the handle 205 is held to cover the top of the storage cylinder 201 with the dustproof cover 204. The powder flows down along the guide cone 202 in the storage cylinder 201 and is pushed down along the discharge pipe 203 by the spiral pusher blade 302, falling into the water flow in the machine housing 101, thus realizing the addition of medicine;

[0028] In this embodiment: the follower device includes a central rotating shaft 301, a force-bearing component is installed at the bottom of the central rotating shaft 301, spiral pushing blades 302 are evenly arranged on the central rotating shaft 301, and a stirring component for breaking up powder bridging is installed at the top of the central rotating shaft 301; the force-bearing component includes a first connecting sleeve 303, and a plurality of force-bearing plates 304 are evenly distributed around the circumference of the first connecting sleeve 303; the stirring component includes a second connecting sleeve 305, and a plurality of stirring rods 306 are evenly distributed around the circumference of the second connecting sleeve 305; the force-bearing plates 304 are rectangular, and the stirring rods 306... 06 adopts a cylindrical shape; the flow of sewage drives the force plate 304 to rotate, and the rotation of the force plate 304 changes with the water flow. At the same time, the force plate 304 drives the central rotating shaft 301 to rotate under the support of the fixed frame 104 through the first connecting sleeve 303, so that the spiral pusher blade 302 pushes the powder down along the feed pipe 203. The rotation of the central rotating shaft 301 drives the stirring rod 306 to rotate in the machine box 101 through the second connecting sleeve 305, breaking the bridging generated when the powder flows down along the guide cone 202 in the storage cylinder 201, ensuring that the powder flows down smoothly.

[0029] Working principle: The cover 105 is fixedly connected to the body 101, and the sealing gasket 106 ensures the seal of the contact surface. Pour the powder into the storage cylinder 201, and hold the handle 205 to place the dust cover 204 on top of the storage cylinder 201. During operation, wastewater flows into the body 101 from the inlet pipe 102, pushing the force plate 304 to rotate, and then flows out from the outlet pipe 103. During this process, the rotation of the force plate 304 changes with the water flow. The first connecting sleeve 303 drives the central rotating shaft 301 to rotate under the support of the fixed frame 104, causing the spiral pusher blade 302 to push the powder down along the feed pipe 203 and fall into the water flow inside the machine housing 101, thus realizing the addition of medicine. The rotation of the central rotating shaft 301 drives the stirring rod 306 to rotate inside the machine housing 101 through the second connecting sleeve 305, breaking the bridging generated when the powder flows down along the guide cone 202 in the storage cylinder 201, ensuring that the powder flows down smoothly.
