Description

Technical Field

[0001] This utility model belongs to the technical field of environmental protection equipment, and in particular relates to a reagent dosing and mixing tank. Background Technology

[0002] A chemical dosing system is an automated equipment used in water treatment systems. It is primarily used to add coagulants such as polyaluminum chloride (PAC), PAM, and ferric salts, and is widely used in waterworks, wastewater treatment plants, industrial circulating water systems, swimming pools, and other fields. This system ensures effective water treatment, improves system efficiency, and reduces operating costs by precisely controlling the dosage.

[0003] The dosing device also functions as a pre-dissolving device, allowing precise control of the dosage. This enables some difficult-to-dissolve agents to dissolve rapidly under the high-speed stirring action of the dosing device before being released into tap water. Some agents are in solid granular form, such as aluminum sulfate. While granular form is cheaper, its dissolution efficiency is low. Existing dosing tanks are enormous, with capacities ranging from 40-60L, to meet the required dissolution saturation. Due to the large water capacity of these tanks, larger stirring equipment is needed, resulting in high energy consumption and affecting the lifespan of the tank due to the kinetic energy generated, while also producing significant noise. Therefore, this invention improves the dosing method based on the characteristics of existing dosing tanks, reducing energy consumption and increasing dissolution efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a drug dosing and mixing tank that improves the dosing method, reduces energy consumption, and increases dissolution efficiency based on the characteristics of existing drug dosing and mixing tanks.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A pharmaceutical dosing mixing tank includes a cylindrical tank body with an upper open side. A small mixing drum is detachably installed on the open side. The body of the mixing drum is fixed to the upper open side of the tank body, and the bottom of the mixing drum is a fine-pore filter screen.

[0007] The upper side of the mixing tank is open and is equipped with a stirring device.

[0008] It includes a water pump installed on the side of the tank, the water pump being connected in series with a first pipe, the lower end of the first pipe being connected to the bottom of the tank and the upper end being connected to the mixing tank, and being controlled by a first valve. The first pipe is also connected to a second pipe, which is controlled by a second valve.

[0009] Furthermore, the tank body has a support frame at the bottom for elevation, the top of the tank body is conical, the bottom is conical, and the tip of the conical bottom is connected to the first pipe body.

[0010] Furthermore, the stirring device includes a motor, the motor shaft of which extends into the stirring tank and is equipped with a stirring paddle. The upper open side of the stirring tank has a support ring that supports a cover plate, the cover plate being used to support the motor. The cover plate is hinged to one side of the support ring for flipping, and grooves are formed between the cover plate and the support ring for installing sealing rings.

[0011] This invention has the following advantages: The upper end of the first pipe is connected to the upper part of the mixing tank. This reagent addition mixing tank is mainly used to dissolve insoluble solid reagents, such as granular aluminum sulfate in a crystalline state. The reagent is added to the mixing tank through the opening on the upper side, and a pre-measured amount of water is added to the tank. The second valve is closed, the first valve is opened, and the water pump is turned on to inject water into the mixing tank. Under the action of the stirring device, the added reagent is dissolved. The dissolved water enters the tank directly through the filter screen, forming a circulating dissolution process until the added reagent is completely dissolved. Then, the stirring device and the first valve are closed. When it is necessary to discharge the dissolved reagent, ensure that the first valve is closed, open the second valve, and discharge the reagent by the water pump. Attached Figure Description

[0012] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.

[0013] Figure 1 : Schematic diagram of the structure of this utility model.

[0014] The components represented by each number in the attached diagram are listed below: Tank 1, Mixing Tank 2, Filter Screen 7, Water Pump 3, First Pipe 4, First Valve 41, Second Pipe 5, Second Valve 51, Motor 6, Mixing Paddle 61, Support Ring 21, Cover Plate 22, Sealing Ring 23. Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] like Figure 1 As shown: A reagent dosing mixing tank includes a cylindrical tank body 1 with an open upper side. A small mixing tank 2 is detachably installed on the open upper side. The body of the mixing tank 2 is fixed to the open upper side of the tank body 1. The bottom of the mixing tank is a fine-pore filter screen 7. The mixing tank is fitted into the open side of the tank body, with its lower half inside the tank body and its upper half on the upper side of the tank body. The filter screen is a metal structure filter screen with filter holes of approximately 3 mm in diameter.

[0017] The upper side of the mixing tank 2 is open and equipped with a stirring device;

[0018] It includes a water pump 3 installed on the side of the tank 1, the water pump 3 being connected in series with the first pipe 4, the lower end of the first pipe 4 being connected to the bottom of the tank 1 and the upper end being connected to the mixing tank 2, and being controlled by the first valve 41. The first pipe 4 is also connected to the second pipe 5, and is controlled by the second valve 51.

[0019] The upper end of the first pipe is connected to the upper part of the mixing tank. This reagent addition mixing tank is mainly used to dissolve poorly soluble solid reagents, such as granular aluminum sulfate in a crystalline state. The reagent is added to the mixing tank through the opening on the upper side, with a pre-measured amount of water added to the tank. The second valve is closed, the first valve is opened, and the water pump is turned on to inject water into the mixing tank. Under the action of the stirring device, the added reagent is dissolved. The dissolved water passes directly into the tank through a filter, forming a circulating dissolution process until the added reagent is completely dissolved. Then, the stirring device and the first valve are closed. When it is necessary to discharge the dissolved reagent, ensure the first valve is closed, open the second valve, and use the water pump to discharge the reagent.

[0020] To prevent the drug particles from clogging the filter screen in the mixing tank, the stirring device mainly makes the drug vortex rotate in the mixing tank. Because the mixing tank is small, the stirring device does not need a lot of power to operate, and the stirring rate can be increased to improve the solvent rate.

[0021] The tank 1 has a support frame at the bottom for elevation. The top and bottom of the tank 1 are conical, with the pointed tip of the bottom cone connecting to the first tube 4. The conical bottom facilitates the complete outflow of the reagent, preventing residue buildup inside the tank. The pointed bottom of the tank also has an open side, sealed with a threaded cap for easy disassembly, cleaning, and protection of the tank's interior.

[0022] The stirring device includes a motor 6, whose shaft extends into the stirring tank 2 and is equipped with a stirring paddle 61. The stirring paddle directs the stirring force downwards to increase the dynamic force of the solution and facilitate the flow through the filter screen. Due to the smaller size of the stirring tank, the stirring paddle and the motor do not require high power or large size to achieve a good and vigorous stirring effect. The upper open side of the stirring tank 2 has a support ring 21 that supports a cover plate 22, which supports the motor 6. The cover plate is detachably installed on the upper open side of the stirring tank for easy removal of the cover plate for adding chemicals. The cover plate 22 is hinged to the support ring 21 on one side for flipping the cover plate 22. Grooves are provided between the cover plate 22 and the support ring 21 for installing sealing rings 23. The convenient opening and closing cover plate structure has an annular groove with a circular arc cross-section, which is fitted with an annular rubber sealing ring to improve sealing and prevent liquid splashing and escape during stirring.

[0023] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
