Description

Technical Field

[0001] The utility model relates to the technical field of coating production equipment, in particular to a mixing device for producing waterproof coatings. Background Art

[0002] The general-purpose waterproof coating is a two-component waterproof material composed of a liquid material composed of acrylic emulsion and additives and a powder material composed of cement, sand and mineral powder in a specific proportion. After the two materials are mixed, a chemical reaction occurs, forming a surface coating for waterproofing and also penetrating into the base material to form crystals to block the passage of water, achieving a double waterproof effect. The waterproof film formed after the waterproof coating is cured has certain extensibility, elastoplasticity, crack resistance, impermeability and weather resistance, and can play a role in waterproofing, anti-seepage and protection.

[0003] In the existing waterproof coating mixing device, after adding each raw material into the mixing cylinder according to the proportion, a stirring device is used to drive the stirring shaft or stirring blades to rotate through a motor, so that each raw material of the waterproof coating can be fully mixed. However, in the existing waterproof coating mixing device, during the mixing process, due to the viscosity of the waterproof coating, a small amount of the mixture adheres to the inner wall of the mixing device; even after the mixing process in the mixing device is completed and each raw material is fully mixed, relying on gravity, the waterproof coating will automatically flow to the discharge pipe for discharging. However, considering the viscosity of the waterproof coating, there will still be a small amount of the mixed waterproof coating adhering to the inner wall of the mixing cylinder or the outer wall of the stirring shaft or stirring blades; if not cleaned up in time, on the one hand, it will cause waste of a small amount of waterproof coating, and on the other hand, it will also affect the progress of the next mixing process in this mixing cylinder, otherwise it will cause the situation that the remaining adhered waterproof coating is mixed with each raw material of the next mixing process, affecting the final quality of the waterproof coating. At present, for cleaning the remaining adhered waterproof coating in the mixing device, not only the cleaning effect is not ideal, but also it is time-consuming and laborious.

[0050] Specifically, the mixing device for producing waterproof coating further comprises an inverted U-shaped mounting groove body 21, and the first lead screw 24, the second lead screw 27, the first motor 22 and the second motor 25 are all mounted on the mounting groove body 21.

[0051] The working principle of the utility model is as follows:

[0052] During the mixing process, each raw material of the waterproof coating is transported to the mixing chamber 102 by the feed pipe 10, and the valves on the feed pipe 10 and the discharge pipe 11 are closed; the plugging plate 7 completely plugs all the air inlet holes 5; the third motor 12 is started to work, and the motor shaft of the third motor 12 drives the stirring shaft 13 and the stirring rod 14 to rotate, so as to fully mix each raw material in the mixing chamber 102.

[0053] After the mixing process is completed, the third motor 12 stops working, and the valve on the discharge pipe 11 is opened. By relying on gravity, the mixed waterproof coating is transported to the next production and processing device by the discharge pipe 11; due to the viscosity of the waterproof coating, a small amount of the mixed waterproof coating still adheres to the inner wall of the mixing cylinder 1, the stirring shaft 13 or the outer wall of the stirring blades.

[0054] The second motor 25 is started to work, and the motor shaft of the second motor 25 drives the second lead screw 27 to rotate. The second lead screw 27 drives all the air inlet pipes 6 to move upward. When the plugging plate 7 completely disengages from the air inlet holes 5, the second motor 25 stops working. At this time, all the air inlet pipes 6 are still in the air inlet chamber 101, and the plugging plate 7 no longer plugs the air inlet holes 5; the valve on the air inlet main pipe 16 is opened and the air pump is started to work. The gas is transported from the air collecting chamber 9, each air inlet pipe 6 and the air outlet channel 8 to the air inlet chamber 101 at a high speed, and then is sprayed into the mixing chamber 102 through each air inlet hole 5 at a high speed. By the force of the high-speed gas eruption, a small amount of the waterproof coating adhering to the inner wall of the mixing cylinder 1, the stirring shaft 13 or the outer wall of the stirring blades is sprayed down and collected on the discharge pipe 11, so as to effectively clean the slightly adhered waterproof coating.

[0055] If the cleaning liquid is input into the mixing cylinder 1 through the feed pipe 10, the high-speed gas can still be sprayed into the mixing cylinder 1 through the air inlet pipe 6 by the above principle to assist in cleaning the adhered waterproof coating, and the cleaning efficiency is greatly improved.

[0056] Finally, after the second motor 25 stops working, the first motor 22 starts to work. The motor shaft of the first motor 22 drives the first lead screw 24 to rotate, and the first lead screw 24 drives the push rod 28 and the edge partition 4 to move downward. When the edge partition 4 moves downward to a position close to the inner bottom wall of the mixing cylinder 1, the first motor 22 stops working. During the downward movement of the edge partition 4, it plays a role in scraping off the waterproof coating adhered to the inner wall of the mixing cylinder 1, and the cleaning efficiency is very good.

[0057] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
