Description

Technical Field

[0001] This utility model relates to the field of waterproof coating mixing technology, specifically to a mixing tank for waterproof coatings. Background Technology

[0002] Waterproof coatings are materials applied to surfaces to prevent moisture penetration. These coatings can be applied to a variety of surfaces, including walls, roofs, floors, and other building structures, to prevent water penetration and protect the surface from water damage. Waterproof coatings are usually stored separately in powder and liquid form before use and need to be mixed using a mixing container.

[0003] However, most existing mixing tanks directly mix powdered and liquid raw materials during use. Powdered raw materials tend to settle at the bottom of the mixing tank, resulting in incomplete mixing of powdered and liquid materials and reducing the performance of waterproof coatings. Utility Model Content

[0004] The purpose of this invention is to design a mixing container for waterproof coatings, which can solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A mixing tank for waterproof coating includes a tank body, an internal stirring shaft, stirring blades on the outer surface of the stirring shaft, an internal cavity inside the stirring shaft, an opening at the bottom of the stirring shaft communicating with the internal cavity, an inner shaft at the top of the internal cavity, spiral blades on the outer surface of the inner shaft, the outer side of the spiral blades being in close contact with the inner wall of the internal cavity, a plurality of through holes on the side of the stirring shaft communicating with the top of the internal cavity, a motor, a powder inlet, and a liquid inlet at the top of the tank body, and the output end of the motor penetrating into the interior of the tank body and fixedly connected to the top end of the stirring shaft.

[0006] Furthermore, the lower part of the tank has a conical structure that is wider at the top and narrower at the bottom, and a discharge pipe is connected to the bottom of the tank.

[0007] Furthermore, the outer surface of the stirring shaft is provided with a shell that encloses the through hole, and the side of the shell is provided with a plurality of leakage holes distributed in a ring.

[0008] Furthermore, the bottom of the housing has a conical structure that is narrower at the top and wider at the bottom.

[0009] Furthermore, an electronic flow meter is connected to the liquid outlet, and the other end of the electronic flow meter is connected to the feed hopper via an electric valve. The electronic flow meter and the electric valve are electrically connected via a controller.

[0010] Furthermore, the electric valve is an electric three-way valve, the third port of the electric valve is connected to an overflow pipe, a bracket is fixedly connected to the side of the tank, a recycling bin is placed on the bracket, and the outlet of the overflow pipe is located directly above the recycling bin.

[0011] Furthermore, the lower part of the tank is fixedly connected with support legs.

[0012] The beneficial effects of this utility model are as follows: When the stirring shaft rotates, the spiral blades inside the stirring shaft will transport the material at the bottom of the tank from bottom to top and flow out from the through hole. Then, the stirring blades will stir and mix it, which can prevent the powdered raw materials from settling at the bottom of the tank. This ensures that the powdered and liquid raw materials in the waterproof coating are fully and evenly mixed, thus avoiding a reduction in the performance of the waterproof coating.

[0013] The outer side of the spiral blades is in close contact with the inner wall of the cavity, which can prevent materials from falling through the gap between the outer side of the spiral blades and the inner wall of the cavity, thereby improving the conveying efficiency of materials and thus improving the mixing efficiency of powdered and liquid raw materials.

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] like Figure 1-4 As shown, a mixing tank for waterproof coatings includes a tank body 1. A stirring shaft 2 is installed inside the tank body 1, and stirring blades 3 are provided on the outer surface of the stirring shaft 2. The stirring shaft 2 drives the stirring blades 3 to rotate, thereby mixing the materials. An inner cavity 4 is provided inside the stirring shaft 2, and an opening communicating with the inner cavity 4 is provided at the bottom end of the stirring shaft 2. An inner shaft 5 is fixedly connected to the top of the inner cavity 4, and spiral blades 6 are fixedly connected to the outer surface of the inner shaft 5. Several through holes 7 are provided on the side of the stirring shaft 2, communicating with the top of the inner cavity 4. When the stirring shaft 2 rotates, the spiral blades 6 rotate accordingly, and the materials are conveyed from bottom to top within the inner cavity 4 and flow out through the through holes 7. After the materials at the bottom of the tank body 1 are removed, a negative pressure is formed in the middle of the bottom of the tank body 1, causing the materials at the periphery of the bottom of the tank body 1 to flow towards the center, thus allowing the materials at the bottom of the tank body 1 to flow... The movement of the stirring shaft 2 prevents powdered raw materials from settling at the bottom of the tank 1. The outer side of the spiral blade 6 is in close contact with the inner wall of the inner cavity 4, preventing material from falling through the gap between the outer side of the spiral blade 6 and the inner wall of the inner cavity 4, thus improving the conveying efficiency of the material and the mixing efficiency of the powdered and liquid raw materials. The outer surface of the stirring shaft 2 is provided with a shell 11 that covers the through hole 7. Several drainage holes 12 are distributed in a ring on the side of the shell 11. The material flows into the shell 11 through the through hole 7. As the shell 11 rotates with the stirring shaft 2, the clumps of material inside the shell 11 are dispersed and splashed out by centrifugal force and the drainage holes 12, avoiding material clumping and ensuring the quality of the waterproof coating. The bottom of the shell 11 is a cone structure that is narrow at the top and wide at the bottom, which helps the material inside the shell 11 to converge at the through hole 7 and facilitates the discharge of the material. The top of the tank 1 is equipped with a motor 8, a powder inlet 9, and a liquid inlet. The output end of the motor 8 is inserted into the tank 1 and fixedly connected to the top of the stirring shaft 2. The motor 8 drives the stirring shaft 2 to rotate. Powdered raw materials are fed into the tank 1 through the powder inlet 9, and liquid raw materials are added into the tank 1 through the liquid inlet. The lower part of the tank 1 has a cone-shaped structure that is wider at the top and narrower at the bottom, which facilitates the convergence of materials towards the bottom of the stirring shaft 2 and makes material transportation easier. The bottom of the tank 1 is connected to a discharge pipe 10, and the liquid inlet is connected to an electronic flow meter 13. The other end of the electronic flow meter 13 is connected to a feed hopper 15 through an electric valve 14. The electronic flow meter 13 and the electric valve 14 are electrically connected through a controller. The electric valve 14 is an electric three-way valve, and the third port of the electric valve 14 is connected to an overflow pipe 16, which discharges material into the feed hopper 15. Liquid raw materials are fed in, and then the electronic flow meter 13 detects the amount of liquid raw materials fed in. When the amount of raw materials fed in reaches the preset flow value of the electronic flow meter 13, the controller will control the electric valve 14 to start, disconnecting the feed hopper 15 from the electronic flow meter 13 and connecting the feed hopper 15 to the overflow pipe 16, so that the remaining liquid raw materials can be discharged through the overflow pipe 16. The amount of liquid raw materials added can be precisely controlled according to the actual amount of powdered raw materials added, ensuring the accuracy of the waterproof coating ratio. A bracket 17 is fixedly connected to the side of the tank body 1, and a recycling bin 18 is placed on the bracket 17. The outlet of the overflow pipe 16 is located directly above the recycling bin 18. The liquid raw materials discharged from the overflow pipe 16 will fall into the recycling bin 18 for recycling. A support foot 19 is fixedly connected to the lower part of the tank body 1.

[0019] Working principle: like Figure 1-4 As shown, when using the mixing tank of this utility model, the prepared powdered raw material is first put into the powder inlet 9, and then the electronic flow meter 13 is set according to the amount of powdered raw material added. Then, liquid raw material is added into the feed hopper 15. When the feed amount reaches the preset flow value of the electronic flow meter 13, the controller will control the electric valve 14 to start, disconnect the feed hopper 15 from the electronic flow meter 13, and connect the feed hopper 15 to the overflow pipe 16, so that the remaining liquid raw material is discharged through the overflow pipe 16. The amount of liquid raw material added can be precisely controlled according to the actual amount of powdered raw material added, so as to ensure the accuracy of the waterproof coating ratio. After the powdered and liquid raw materials are added, the motor 8 is started. The motor 8 drives the stirring shaft 2 to rotate. When the stirring shaft 2 rotates, the spiral blades 6 will also rotate. The material will be conveyed from bottom to top in the inner cavity 4 and flow out from the through hole 7. After the material at the bottom of the tank 1 is removed, a negative pressure will be formed in the middle of the bottom of the tank 1. The material at the periphery of the bottom of the tank 1 will flow towards the middle, thereby making the material at the bottom of the tank 1 flow. This can prevent the powdered raw materials from settling at the bottom of the tank 1, and ensure that the powdered and liquid raw materials in the waterproof coating are fully and evenly mixed, thus avoiding a reduction in the performance of the waterproof coating.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
