Description

Technical Field

[0001] The utility model relates to the technical field of water treatment chemical dosing and mixing equipment, in particular to a chemical dosing and mixing device for water treatment. Background Technique

[0002] The water treatment chemical dosing and mixing device is widely used in raw water, feed water treatment systems and wastewater treatment systems, and generally requires quantitative dosing of chemicals and mixing. In the conventional process, a reaction tank is used for mixing, and a stirring mechanism is used to stir and mix the mixed chemicals so that the chemicals are fully dissolved in the sewage. In order to improve the mixing efficiency, an aeration mechanism is currently added to enhance the activity of the sewage, so that the sewage can react with the chemicals quickly. However, it is found in the use process that the current aeration mechanism is generally installed on the base inside the sewage treatment tank. After long-term use, the surface of the aeration mechanism is prone to pollution or blockage, and the disassembly and repair of the aeration equipment are relatively troublesome, which increases the workload of the staff. Therefore, we propose a chemical dosing and mixing device for water treatment. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3, the present utility model provides a technical solution: a chemical dosing and mixing device for water treatment, including a box body 1. A chemical dosing bin 11 is arranged at the top of the box body 1. A stirring mechanism is arranged inside the chemical dosing bin 11. An aeration cylinder 19 is installed in the box body 1 through an installation mechanism. An air outlet 2 is formed on the side of the aeration cylinder 19. Both ends of the aeration cylinder 19 are respectively installed in a first pressing plate 22 and a second pressing plate 23. The first pressing plate 22 and the second pressing plate 23 are connected by a long screw 24 and a nut 25. An air delivery pipe 26 is connected to the end of the aeration cylinder 19. A pipe joint 27 is arranged on the air delivery pipe 26.

[0018] Specifically, a filter screen is arranged inside the air outlet 2. By arranging the aeration cylinder 19 with the air outlet 2 formed on the side, and arranging the air delivery pipe 26 and the pipe joint 27 to connect the aeration cylinder 19 with a gas source device, air flow can be continuously introduced into the box body 1. The air flow impacts the sewage, enabling the sewage to be further mixed with the chemical agent, and further improving the mixing efficiency of the chemical agent and the water treatment effect on the basis of the stirring mechanism.

[0019] In the above solution, support columns 12 are arranged at the bottom of the box body 1.

[0020] In the above solution, a water inlet pipe 13 is arranged on the side of the chemical dosing bin 11. Sewage and the chemical agent are added into the chemical dosing bin 11 through the water inlet pipe 13.

[0021] In the above solution, the stirring mechanism includes a rotating shaft 15 and a plurality of stirring paddles 16 arranged on its side. The top end of the rotating shaft 15 is connected to a motor 14. By arranging the stirring mechanism composed of the rotating shaft 15 and the stirring paddles 16 inside the chemical dosing bin 11, the stirring mechanism can be driven by the motor 14 to continuously stir and mix the sewage, enabling the chemical agent to dissolve in the sewage and improving the stirring effect.

[0022] In the above solution, a side door 17 and an operation panel 18 are arranged on the front of the box body 1. The side door 17 is hinged to the box body 1, and the connection part between the two is sealed and waterproofed. The electric mechanism can be controlled through the operation panel 18.

[0023] In the above solution, positioning seats 21 are arranged inside the first pressing plate 22 and the second pressing plate 23. By arranging the structures such as the first pressing plate 22, the second pressing plate 23, the long screw 24, and the nut 25 to cooperate with each other, the installation and disassembly of the aeration cylinder 19 can be facilitated, and thus the maintenance of the equipment can be facilitated, solving the problem that the aeration mechanism adopted by the current water treatment mechanism is generally not easy to disassemble, and reducing the use cost.

[0024] In the above solution, one end of the long screw 24 is fixed on a bracket 28. The bracket 28 is fixed inside the box body 1.

[0025] Working principle:

[0026] For this chemical dosing and mixing device used for water treatment, during use, a stirring mechanism composed of a rotating shaft 15 and stirring paddles 16 is arranged inside the chemical dosing bin 11. Driven by the motor 14, the stirring mechanism can continuously stir and mix the sewage, enabling the chemical agent to dissolve in the sewage. The pipe joint 27 connected to the air source mechanism introduces air flow into the aeration cylinder 19 and enters the box body 1 through the air outlet 2, continuously introducing air flow into the box body 1. The air flow impacts the sewage, enabling the sewage to further mix with the chemical agent, further improving the mixing efficiency of the chemical agent and the water treatment effect on the basis of the stirring mechanism. When the aeration cylinder 19 needs to be disassembled and replaced, first open the side door 17, then loosen the nut 25 on the long screw 24, so that the first pressing plate 22 and the second pressing plate 23 are separated from each other, and thus the aeration cylinder 19 between the two can be removed, solving the problem that the aeration mechanism used in the current water treatment mechanism is generally not convenient to disassemble. The operation is relatively convenient and the use cost is low.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
