Description

Technical Field

[0001] This utility model relates to the field of coating preparation equipment technology, and in particular to a water-based aluminum alloy texture coating dispersion and grinding equipment. Background Technology

[0002] As a functional coating, water-based aluminum alloy texture coatings have extremely high requirements for the dispersion state and particle size of raw materials. In particular, when dispersing flake pigments such as aluminum powder, sufficient shear force needs to be applied to ensure that the pigments are fully wetted and deagglomerated, but excessive damage to the flake structure of aluminum powder must be avoided.

[0003] In existing coating preparation processes, dispersion and grinding are often carried out in separate steps or with low integration in the same equipment, which limits production efficiency. In particular, for high-viscosity and difficult-to-disperse water-based coatings, simple conventional stirring or sand milling cannot provide efficient and controllable shear force, which can easily cause material agglomeration and affect the final performance and texture of the coating.

[0004] In addition, most existing grinding equipment adopts a fixed grinding structure. When it is necessary to adjust the particle size of the final product, the operation is complicated and the replacement is time-consuming. It cannot quickly adapt to the fine production needs of different batches or different specifications of coatings. Furthermore, the residence time of materials in the grinding area is difficult to control effectively, which may lead to some materials being over-ground or under-ground, further affecting the stability of product quality.

[0005] Therefore, this utility model proposes a water-based aluminum alloy texture coating dispersion and grinding equipment to solve the shortcomings of the prior art, such as low dispersion efficiency, easy agglomeration, inconvenient adjustment of grinding fineness, and uncontrollable material grinding time. Utility Model Content

[0006] In view of the problems existing in the prior art of water-based aluminum alloy texture coating dispersion and grinding equipment, such as insufficient dispersion shear force, easy agglomeration of materials, difficulty in flexibly adjusting grinding fineness, and uncontrollable grinding time, this utility model aims to provide a water-based aluminum alloy texture coating dispersion and grinding equipment with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a water-based aluminum alloy textured coating dispersion and grinding equipment, including: a tank, a motor disposed at the bottom of the tank, a rotating shaft vertically disposed in the tank and connected to the motor for transmission, a feed inlet disposed at the top of the tank, a discharge outlet disposed at the bottom of the tank; and an annular nozzle, a dispersion disc, an impact plate, and a grinding mechanism.

[0008] The annular nozzle is connected to the feed inlet, the dispersing disc is fixedly connected to the top of the rotating shaft, and the dispersing disc is located below the annular nozzle to receive the raw material sprayed out by the annular nozzle. The impact plate is fixed to the inner wall of the tank and located around the dispersing disc.

[0009] Furthermore, the grinding mechanism is located below the dispersing disc. The grinding mechanism includes a grinding plate fixed to the inner wall of the tank and a grinding roller rotatably arranged to cooperate with the grinding plate for grinding. The grinding mechanism also includes a discharge plate fixed to the outer wall of the rotating shaft. Both the discharge plate and the outer wall of the grinding plate are provided with discharge holes. When the discharge plate rotates, it causes the discharge holes to periodically overlap with the discharge holes of the grinding plate to control the material to be discharged to the discharge port.

[0010] Preferably, the water-based aluminum alloy textured coating dispersion and grinding equipment further includes a delivery pump and a circulation pipe; the inlet of the delivery pump is connected to the outlet, and the outlet of the delivery pump is connected to the annular nozzle through the circulation pipe.

[0011] Preferably, the top surface of the dispersing disc is provided with dispersing strips.

[0012] Preferably, the grinding mechanism further includes fastening screws; the fastening screws are used to adjust the distance between the grinding roller and the grinding plate.

[0013] Preferably, the grinding mechanism further includes a locking ring; the grinding roller is fixed to the rotating shaft by the locking ring and rotates together with the rotating shaft.

[0014] Preferably, the fastening screw passes through the locking ring to adjust the radial position of the grinding roller.

[0015] Preferably, the impact plates are arranged at intervals along the inner wall of the tank.

[0016] Preferably, the grinding plate has a ring structure.

[0017] Preferably, the discharge plate is disc-shaped and located below the grinding plate.

[0018] Preferably, both the outer wall of the grinding plate and the outer wall of the discharge plate have at least one discharge hole, and the number and shape of the holes are the same.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, by setting an annular nozzle, a high-speed rotating dispersing disc, and an impact plate fixed in the tank, causes the material to be sprayed under high pressure to the dispersing disc for the first impact, and then thrown out by the dispersing disc to impact the impact plate for the second impact. With the help of the dispersing strips on the dispersing disc to guide the flow of the material, it solves the problems of insufficient shear force for coating dispersion and easy agglomeration of materials in the prior art, and achieves the technical effects of efficient dispersion, prevention of agglomeration, and improvement of coating dispersion uniformity.

[0021] 2. This utility model solves the problems of insufficient grinding due to the inability to flexibly adjust the grinding fineness and the uncontrollable grinding time in the prior art by setting a grinding roller and a grinding plate and adjusting the distance between them with fastening screws. At the same time, it sets discharge holes that can periodically overlap on the fixed grinding plate and the discharge plate that rotates with the rotating shaft. It achieves the technical effect of flexibly adjusting the grinding particle size, ensuring sufficient grinding of materials, and making the discharge uniform and controllable.

[0034] A water-based aluminum alloy textured coating dispersion and grinding equipment also includes a delivery pump 4 and a circulation pipe 5. The inlet of the delivery pump 4 is connected to the outlet 3, and the outlet of the delivery pump 4 is connected to an annular nozzle 6 through the circulation pipe 5, for re-inputting the material into the annular nozzle 6 for multiple dispersion and grinding processes.

[0035] As a preferred embodiment, such as Figure 1 As shown, a water-based aluminum alloy textured coating dispersion and grinding equipment also includes a conveying pump 4 and a circulation pipe 5. The inlet of the conveying pump 4 is connected to the outlet 3, and the outlet of the conveying pump 4 is connected to the annular nozzle 6 through the circulation pipe 5.

Specifically, the fastening screw 202 passes through the locking ring 201 and acts on the grinding roller 203 to adjust the radial position of the grinding roller 203, thereby achieving the grinding requirements of different particle sizes.

[0040] Working principle: When producing water-based aluminum alloy base coating, the raw material is input from the feed inlet 10 and sprayed out from the annular nozzle 6 at high pressure. The sprayed raw material first impacts the top surface of the dispersion disc 7. The motor 11 at the bottom of the tank 1 drives the rotating shaft 12 to rotate. The top of the rotating shaft 12 is fixedly connected to the middle of the bottom surface of the dispersion disc 7. The dispersion disc 7 rotates at high speed, throwing the raw material on the top surface of the dispersion disc 7 out to impact the impact plate 9 fixed on the inner wall of the tank 1 for a second impact, thereby achieving efficient dispersion. The dispersion strip 8 at the top of the dispersion disc 7 guides the material to form a specific flow path, further enhancing the dispersion effect and effectively preventing the occurrence of material agglomeration. After dispersion, the raw material is ground by the grinding mechanism 2 and discharged from the discharge port 3, or it can be re-input into the annular nozzle 6 by the conveying pump 4 through the circulation pipe 5 for multiple dispersion and grinding processes.

[0041] After the material flows down from the dispersing disc 7, it reaches the top surface of the grinding plate 204. The grinding plate 204 is fixed to the inner wall of the tank 1. The motor 11 drives the locking ring 201 and the grinding roller 203 to rotate. The distance between the grinding roller 203 and the grinding plate 204 can be adjusted by the fastening screw 202 to achieve grinding of different particle sizes. The discharge plate 205 is fixed to the outer wall of the rotating shaft 12. The outer walls of the discharge plate 205 and the grinding plate 204 are provided with the same discharge holes 206. Every time the rotating shaft 12 rotates once, the two discharge holes 206 overlap once, so that the ground material can be discharged from the discharge port 3.
