Description

Technical Field

[0001] This utility model relates to the field of zinc-aluminum coating preparation technology, specifically a dilution device for preparing zinc-aluminum coating. Background Technology

[0002] Zinc-aluminum coating is a novel metal surface anti-corrosion treatment technology developed by Shenyang Hangda Technology Co., Ltd. It can be directly applied to the substrate without electroplating. Its core components are a composite coating composed of ultrafine zinc and aluminum powder, chromium-free binder, and environmentally friendly passivating agent. The coating structure is dense, and the physical shielding and electrochemical protection of the zinc-aluminum coating work synergistically to effectively isolate corrosive media. It is widely used for corrosion protection of fasteners such as automotive chassis and body connecting parts, accounting for up to 40% of applications. The preparation of zinc-aluminum coating typically involves mixing nano-sized zinc powder, aluminum powder, organic solvents, and other raw materials in a specific ratio to form a coatable liquid state. To improve the preparation efficiency of zinc-aluminum coating, a dilution device is needed; however, existing dilution devices still have the following shortcomings:

[0003] When existing dilution devices are used, most of them only have a relatively simple mixing structure, which makes it difficult for the solution to be fully dispersed, resulting in a slow mixing speed. At the same time, the simple mixing structure can increase the energy consumption of the equipment and may also increase the noise, causing the dilution device to become less practical and less efficient. Utility Model Content

[0004] The purpose of this invention is to provide a dilution device for preparing zinc-aluminum coating solution, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dilution device for preparing zinc-aluminum coating liquid, comprising a main tank and a mixing assembly. The main tank is provided with an upper mounting cover and a support column is installed at the bottom of the main tank. The mixing assembly is provided inside the main tank and includes a servo motor, a support rod, a mounting ring, a lower blade, and an upper blade. The front end of the servo motor is connected to the support rod, and the lower end of the support rod is provided with a mounting ring. A lower blade is added outside the mounting ring, and an upper blade is provided above the lower blade. An installation assembly is provided outside the mounting cover.

[0006] Furthermore, the internal dimensions of the mounting cover are adapted to the external dimensions of the main tank, and the mounting cover is connected to the main tank.

[0007] Furthermore, the support rod is embedded in the main tank body, and the support rod is rotatably connected to the main tank body via a servo motor.

[0008] Furthermore, the lower blades are perpendicular to the mounting ring, and the lower blades are fixedly connected to the mounting ring by bolts.

[0009] Furthermore, the installation assembly includes a limiting cylinder, a limiting crossbar, a return spring, and a limiting through hole. The limiting cylinder is connected to the limiting crossbar, and a return spring is provided inside the limiting cylinder outside the limiting crossbar. A limiting through hole is provided at the upper end of the main tank.

[0010] Furthermore, the number of the limiting cylinders is set to two, and the two limiting cylinders are symmetrically arranged on both sides of the outer side of the mounting top cover with respect to the central axis of the front of the mounting top cover.

[0011] Furthermore, the limiting crossbar is embedded in the limiting cylinder, and the limiting crossbar is elastically connected to the limiting cylinder through a return spring.

[0012] Furthermore, the external dimensions of the limiting crossbar are adapted to the internal dimensions of the limiting through hole, and the limiting crossbar is connected to the main tank body through the limiting through hole.

[0013] This invention provides a dilution device for preparing zinc-aluminum coating solution, which has the following beneficial effects:

[0014] 1. This utility model, through the setting of the mixing component, enables the servo motor to drive the support rod to rotate during the use of the dilution device for zinc-aluminum coating solution preparation. The mounting ring is then fitted onto the outside of the support rod and fixed with fastening bolts. This fixes the lower blade installed outside the mounting ring to the support rod. The lower blade is close to the bottom of the device and can agitate the deposited zinc-aluminum particles. Similarly, the upper blade is fixed to the support rod. The upper blade is tilted at a 45° angle, which enhances the vertical convection of the solution, improves the solution mixing efficiency, and increases the overall practicality of the dilution device.

[0015] 2. By setting up the installation components, this utility model enables the limiting crossbar to be elastically connected to the limiting cylinder through the reset spring inside the limiting cylinder when the zinc-aluminum coating preparation dilution device is used. This allows the installation top cover to be snapped into place with the main tank. The limiting crossbar, in conjunction with the limiting through hole, completes the fixed installation of the installation top cover and the main tank, thereby making the installation top cover easy to disassemble and improving the overall practicality and efficiency of the dilution device.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1 to 3 As shown, a dilution device for preparing zinc-aluminum coating liquid includes a main tank 1 and a mixing assembly 4.

The mixing assembly 4 is located inside the main tank 1 and includes a servo motor 401, a support rod 402, a mounting ring 403, a lower blade 404, and an upper blade 405. The front end of the servo motor 401 is connected to the support rod 402, and a mounting ring 403 is provided on the lower part of the support rod 402. A lower blade 404 is added to the outside of the mounting ring 403, and an upper blade 405 is provided above the lower blade 404. The internal dimensions of the mounting top cover 2 are adapted to the external dimensions of the main tank 1, and the mounting top cover 2 is connected to the main tank 1. The support rod 402 is embedded in the main tank 1 and is rotatably connected to the main tank 1 via the servo motor 401. The lower blade 404 and the support rod 402 are connected to the main tank 1 in a rotatable manner. The mounting rings 403 are vertically distributed, and the lower blades 404 are fixedly connected to the mounting rings 403 by bolts. The servo motor 401 is fixedly installed in the middle of the upper part of the mounting top cover 2 by fastening bolts. The output shaft of the servo motor 401 is connected to the support rod 402 through a coupling. The operation of the servo motor 401 drives the support rod 402 to rotate. The internal dimensions of the mounting rings 403 are adapted to the external dimensions of the support rod 402. The mounting rings 403 are fitted onto the outside of the support rod 402 and then fixed with fastening bolts, so that the lower blades 404 installed on the outside of the mounting rings 403 are fixed to the support rod 402. The lower blades 404 are close to the bottom of the device and can agitate the deposited zinc and aluminum particles. Similarly, the upper blades 405 are fixedly installed to the support rod 402. The upper blades 405 are tilted at a 45° angle, which enhances the vertical convection of the solution, improves the solution mixing efficiency, and increases the overall practicality of the dilution device.

[0022] like Figure 1 and Figure 3As shown, an installation assembly 5 is provided on the outside of the mounting top cover 2. The installation assembly 5 includes a limiting cylinder 501, a limiting crossbar 502, a return spring 503, and a limiting through hole 504. The limiting cylinder 501 is internally connected to the limiting crossbar 502, and the limiting crossbar 502 is externally located inside the limiting cylinder 501 with a return spring 503. A limiting through hole 504 is provided at the upper end of the main tank body 1. There are two limiting cylinders 501, which are symmetrically arranged on both sides of the outside of the mounting top cover 2 about the central axis of the front of the mounting top cover 2. The limiting crossbar 502 is embedded in the limiting cylinder 501 and elastically connected to the limiting cylinder 501 through the return spring 503. The external dimensions of the limiting crossbar 502 and the internal dimensions of the limiting through hole 504 are similar. The dimensions are compatible, and the limiting crossbar 502 is connected to the main tank 1 through the limiting through hole 504. The limiting cylinder 501 is fixedly installed on both sides of the outside of the mounting top cover 2 by fastening bolts. The limiting crossbar 502 is installed inside the limiting cylinder 501. The limiting crossbar 502 is elastically connected to the limiting cylinder 501 by the return spring 503 set inside the limiting cylinder 501. The mounting top cover 2 is snapped into place with the main tank 1. The external dimensions of the limiting crossbar 502 are compatible with the internal dimensions of the limiting through holes 504 opened on both sides of the upper end of the main tank 1. Thus, the mounting top cover 2 and the main tank 1 are fixedly installed by the limiting crossbar 502 and the limiting through hole 504. This makes the mounting top cover 2 easy to disassemble and improves the overall practicality and efficiency of the dilution device.

[0023] In summary, the dilution device for preparing zinc-aluminum coating solution, during use, firstly increases the stability of the equipment during operation through the support column legs 3 installed at the bottom of the main tank 1. The return spring 503 inside the limiting cylinder 501 elastically connects the limiting crossbar 502 to the limiting cylinder 501, thereby snapping the mounting top cover 2 onto the main tank 1. The limiting crossbar 502, in conjunction with the limiting through hole 504, completes the fixed installation of the mounting top cover 2 onto the main tank 1, thus facilitating the removal of the mounting top cover 2. Then, the servo motor... Operation 401 drives the support rod 402 to rotate, and the mounting ring 403 is fitted onto the outside of the support rod 402 and then fixed with fastening bolts. This fixes the lower blade 404, which is installed on the outside of the mounting ring 403, to the support rod 402. The lower blade 404 is close to the bottom of the device and can agitate the deposited zinc and aluminum particles. Similarly, the upper blade 405 is fixed to the support rod 402. The upper blade 405 is tilted at a 45° angle, which enhances the vertical convection of the solution, improves the solution mixing efficiency, and increases the overall practicality of the dilution device.
