Description

Technical Field

[0001] The utility model relates to the technical field of polyurea coatings, in particular to a dynamic feeding device for producing polyurea waterproof coatings. Background Art

[0002] Polyurea coating adopts a one-time coating process. No matter how large the area is, there is no joint seam. It is also a dust-free material polyurea coating with the characteristics of strong adhesion, friction resistance, and strong hardness. The dispersion kettle is mainly used for crushing, dispersing, emulsifying and mixing raw materials. It can strongly shear, impact, crush and disperse the materials through high-speed rotation to achieve the purpose of rapid mixing, dissolving and refining.

[0003] For example, the Chinese patent application number is "202222041148.2", which is a crushable coating dispersion device for the production of polyurea coatings, comprising a box, the bottom of which is fixedly connected to a support rod, the top of which is movably connected to a piston column, the top of which is fixedly installed with a starter, the bottom of which is fixedly connected to a discharge pipe, and the output end of the starter is fixedly connected to a rotating shaft. This solution can disperse the raw materials evenly.

[0004] Since the raw material concentration of polyurea waterproof coatings has errors within the standard range, the detection performance indicators will not meet the standards after the dispersion of multiple mixtures due to concentration errors. Therefore, a device that can dynamically feed according to the indicator errors is needed. Utility Model Content

The top of the reactor 1 is provided with an inspection cover 3, and the top of the inspection cover 3 is provided with a secondary feeding mechanism 4, which is controlled by the signal of the detection port 2, and the secondary feeding mechanism 4 includes a powder feeding mechanism 41 and a liquid feeding mechanism 42, and the discharge end of the secondary feeding mechanism 4 is connected to and through the reactor 1.

[0023] The powder feeding mechanism 41 includes a feeding hopper 411, which is fixedly installed above the inspection cover 3 and connected to the reactor 1. A storage hopper 412 is arranged above the feeding hopper 411, and a roller 413 is arranged in the middle of the feeding hopper 411. A notch 414 is opened on the surface of the roller 413. A motor 415 is arranged on the outside of the feeding hopper 411, and the output end of the motor 415 is fixedly connected to the roller 413. Through such an arrangement, the motor 415 can be used to drive the roller 413 to rotate, so that a unit amount of powdered raw material is carried in the notch 414 for feeding.

[0024] The liquid feeding mechanism 42 includes a piston sleeve 421, the feed end and the discharge end of the piston sleeve 421 are connected and penetrated by a one-way valve 422, the discharge end of the piston sleeve 421 is provided with a nozzle 423, the nozzle 423 is connected to the reactor 1, the feed end of the piston sleeve 421 is provided with a silo 424, the silo 424 is connected to the one-way valve 422, and the control end of the piston sleeve 421 is provided with a telescopic mechanism 425, and the telescopic mechanism 425 can be used to control the suction and discharge amounts by setting the piston.

[0025] The telescopic mechanism 425 includes a rack plate 426, which is fixedly connected to the piston pad. The motor 415 is fixedly installed above the piston sleeve 421. The output end of the motor 415 is fixedly installed with a gear 427 that meshes with the rack plate 426. Through this arrangement, the motor 415 can be used to drive the piston pad to move.
