Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coating production, in particular to a mixer for waterproof coating production. Background Art

[0002] There are two major types of waterproof materials installed in the market: one is polyurethane waterproof coating. This type of material is generally made of polyurethane and coal tar as raw materials. The tar gas it emits is highly toxic and difficult to remove, so it was banned in China in 2000. The polyurethane waterproof coating that is still on sale uses asphalt instead of coal tar as raw material. However, when using this kind of coating, it is generally diluted with organic solvents such as toluene and xylene, so it is also toxic; the other type is polymer cement-based waterproof coating, which is composed of an emulsion synthesized from a variety of water-based polymers and high-quality cement mixed with various additives. The flexibility of the polymer is combined with the rigidity of the cement, making it excellent in impermeability and stability. Its advantages are convenient construction, low comprehensive cost, short construction period, and non-toxic and environmentally friendly. Therefore, polymer cement-based has become the protagonist of the waterproof coating market.

[0003] The Chinese utility model patent with the authorization announcement number "CN208482335U" is specifically "a dispersing mixer for waterproof coating production". The specific implementation method of its specification records that "the raw materials are poured in from the feed pipe, the rotating motor and the driving motor are started, the rotating motor drives the driving shaft, the driving shaft drives the first gear, the first gear drives the second gear, the second gear drives the driven shaft to rotate, the driving shaft drives the first stirring blade to stir, the driven shaft drives the second stirring blade to stir, at the same time, the driving motor drives the rotating shaft, the rotating shaft drives the slide plate to rotate, the slide plate drives the driven shaft to rotate, and the driven shaft drives the second stirring blade to move and stir, thereby improving the effect of dispersing and stirring";

[0004] The above-mentioned device moves the position of the stirring blade during the stirring process, and although it can improve the stirring effect, the raw materials poured in through the feed pipe of the above-mentioned device will be concentrated and discharged in a corner of the inner wall of the fixed box. Although the rotation of the stirring structure can drive the liquid raw material in the stirring tube to flow, and gradually mix and disperse the raw materials poured from the feed pipe, this process takes a long time, which reduces the stirring efficiency of the overall equipment. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides a mixer for waterproof coating production, which can effectively solve the problem of low mixing efficiency in the prior art.

Embodiment 2

[0029] Reference Figure 1-7, which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: a dust cover 13 is provided at the top loading port of the upper hopper 11 to prevent dust and impurities from entering the mixing tank 1. A support frame 14 is installed at the bottom of the mixing tank 1. A feeding pipe 15 is connected to the bottom feeding port of the mixing tank 1.
