Description

Technical Field

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

[0002] During the coating production process, in order to prevent the coating from agglomerating, an appropriate amount of anti-caking agent is usually added thereto. This operation process needs to be carried out in a coating machine.

[0003] The existing coating machines usually pour the paint first, and then spray the anti-caking agent into the paint, stirring while spraying, so that the surface of the paint is evenly coated with a layer of anti-caking agent. This method has a long history.

[0004] As people's requirements for coating quality gradually increase, coating particles are getting smaller and smaller. The traditional stirring method of coating anti-caking agent has gradually failed to meet actual needs. For this reason, our company has developed this coating machine, which can spray anti-caking agent on the coating during the dynamic centrifugal movement to achieve the purpose of sufficient coating with finer particle size.

[0028] like Figure 1 As shown, the top of the centrifugal cylinder 2 extends to the interior of the machine body 1, an arc-shaped material guide platform 3 is provided at the bottom of the inner wall of the machine body 1, the bottom of the centrifugal cylinder 2 is fixed to the top of the arc-shaped material guide platform 3, a first motor 4 is provided at the bottom of the machine body 1, a centrifugal shaft 5 is installed at the output end of the first motor 4, and the centrifugal shaft 5 passes through the arc-shaped material guide platform 3 and extends to the interior of the centrifugal cylinder 2.

[0029] like Figure 2 As shown, the centrifugal shaft 5 includes a centrifugal stirring shaft 51 and a screw feeding shaft 52 , wherein the centrifugal stirring shaft 51 is located in the centrifugal section 23 , and the screw feeding shaft 52 is located in the feeding section 22 .

[0030] like Figure 2 As shown, the inner cavity of the arc-shaped material guiding platform 3 is provided with a heating tube 6. Turning on the heating tube 6 can increase the temperature in the machine body 1 and accelerate the mixing of the coating and the anti-caking agent.

[0031] like Figure 1 , 5As shown, a box body 7 and a pump 8 are respectively provided on the outside of the machine body 1, and an injection rack 9 is installed in the inner cavity of the machine body 1. The injection rack 9 is composed of a plurality of groups of annular injection pipes 91 interconnected with each other. The number of the injection pipes 91 is not less than four groups, and the lowest injection pipe 91 is not less than 50 centimeters high from the arc-shaped material guide platform 3. The pump 8 is used to spray the oily anti-caking agent in the box body 7 through the injection rack 9.

[0032] like Figure 1 , 3 as well as Figure 4 As shown, a second motor 10 is provided on the top of the body 1, and an annular slide rail 12 and a rotatable gear 11 are respectively provided on the top of the inner wall of the body 1. The gear 11 is driven by the second motor 10. A rotatable ring gear 13 is installed on the annular slide rail 12, and the ring gear 13 is meshed with the gear 11.

The pump 8 draws out the anti-caking agent in the box body 7 and sprays it out at high speed through the injection rack 9. The paint quickly enters the centrifugal section 23 under the action of the spiral feed shaft 52, and generates centrifugal force under the rotation of the centrifugal stirring shaft 51. The centrifugal force can cause the paint to be thrown out from the discharge trough 24, and the thrown paint is quickly mixed with the anti-caking agent sprayed out at high speed. During the movement, the oily anti-caking agent can be quickly wrapped on the surface of the paint.

[0037] To sum up, the coating machine for chemical production has improved the existing coating and anti-caking agent wrapping method by setting up a centrifugal throwing mechanism. The coating is thrown out at high speed by centrifugal throwing during entering the coating machine, and then mixed with the oily anti-caking agent. Compared with the traditional static passive mixing method, the centrifugal mixing method can mix the coating and the anti-caking agent more evenly, so that fine particles of coating can also be evenly wrapped. Finally, under the action of the stirring mechanism, the purpose of secondary mixing is achieved, thereby greatly improving the wrapping efficiency and being able to meet the wrapping needs of fine particle coatings.
