Description
Technical Field

[0002] Aluminum-zinc composite sacrificial anode coating equipment is a specialized device for preparing zinc-aluminum composite coatings on the surface of metal substrates. It extends the substrate's lifespan by coating an anti-corrosion coating containing zinc and aluminum sheets, combining sacrificial anode protection with physical shielding. The coating equipment typically consists of a storage tank, filter, high-pressure plunger pump, and spray gun, and is commonly used in automotive fasteners, marine engineering, and power transmission and distribution equipment.
[0003] In the prior art, although the filter installed between the high-pressure pump and the storage tank can filter the paint entering the high-pressure pump, most of the paint particles are blocked by the filter plate when the paint passes through the filter. This not only increases the residence time of the paint particles at the filter pores and reduces the flow rate of the paint in the filter, but also causes the paint particles to accumulate in the filter, resulting in increased resistance, which requires the high-pressure pump to continuously replenish the pressure.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figures 1 to 7 As shown, the aluminum-zinc composite sacrificial anode anti-corrosion coating device of this utility model includes a vehicle body 1, on which a storage tank 2 and a high-pressure pump 3 are fixedly installed. A spray gun 4 is fixedly installed on the high-pressure pump 3. A parallel feeding mechanism is provided between the storage tank 2 and the high-pressure pump 3.
[0027] The parallel feeding mechanism includes a support frame 5, a three-way pipe 6, a filter 9, and a mounting base 19. Two support frames 5 are fixed to the vehicle body 1, and filters 9 are fixed to the top of each of the two support frames 5. The mounting base 19 is fixed to the high-pressure pump 3. A three-way pipe 6 is provided between the two support frames 5. The three-way pipe 6 is connected to the two filters 9 through two branch pipes 8. The three-way pipe 6 is connected to the inner cavity of the storage tank 2 through a feeding pipe 7. The mounting base 19 is provided with two feed inlets 20. The feed inlets 20 are connected to the filters 9 through branch pipes 10. A turbine auxiliary component is provided inside the filter 9. An adjustment component is provided on the mounting base 19. During operation, the valves on the branch pipes 8 and 10 on both sides of one filter 9 are closed first, and the valves on both sides of the other filter 9 are opened. The high-pressure pump 3 is started. The paint in the storage tank 2 passes through the feed pipe 7, the three-way pipe 6, and the branch pipe 8 with the valve open, and then enters the filter 9. After being filtered by the filter 9, the paint continues to enter the mounting base 19 along the branch pipe 10 with the valve open. Finally, it is drawn from the mounting base 19 into the spray gun 4 by the high-pressure pump 3. The operator can then use the spray gun 4 to complete the spraying work. When the filter 9 has been used for the specified time, the valves on both sides of the working filter 9 are closed, and another filter 9 is opened. This allows for switching without stopping the machine, ensuring the continuity of the spraying operation. The turbine auxiliary component installed in the filter 9 can reduce the residence time of paint particles at the filter holes during the filtration process, increase the flow rate of paint in the filter 9, and alleviate the problem of increased resistance caused by the accumulation of paint particles in the filter 9.
[0028] The turbine auxiliary assembly includes a motor 11 and turbine blades 13. Two arc-shaped filter plates 14 are symmetrically fixed in the inner cavity of the filter 9. An arc-shaped cavity is formed between the two arc-shaped filter plates 14 and the inner wall of the filter 9, and a filtration cavity is formed between the two arc-shaped filter plates 14. The motor 11 is fixedly installed on the outer wall of the filter 9. A rotating shaft 12 is fixedly connected to the output end of the motor 11. One end of the rotating shaft 12 extends into the filtration cavity and is fixedly connected to multiple sets of turbine blades 13. The turbine blades 13 are adapted to the arc-shaped filter plates 14. During operation, the motor 11 drives the turbine blades 13 on the rotating shaft 12 to rotate. The periodic flow generated by the rotation of the turbine blades 13 can form a directional scouring effect on the surface of the arc-shaped filter plates 14, similar to a self-cleaning effect. This breaks down the impurity layer adhesion structure formed on the surface of the arc-shaped filter plates 14, shortens the residence time of the coating at the arc-shaped filter plates 14, and allows the symmetrically arranged two arc-shaped filter plates 14 to repeatedly filter the passing coating, thus improving the filtration effect.
[0029] Multiple sets of guide plates 15 are uniformly fixed to the outer wall of the arc-shaped filter plate 14. The guide plates 15 are located inside the arc-shaped cavity. A waste discharge trough 16 is provided at the bottom of the filter cavity. A waste discharge pipe 17 is fixed to the bottom of the filter 9. The waste discharge pipe 17 is connected to the waste discharge trough 16. A cover plate 18 is threaded to the bottom end of the waste discharge pipe 17. During operation, by setting the guide plates 15 on the outer side of the arc-shaped filter plate 14, the paint can pass through the area of the arc-shaped filter plate 14 in a laminar flow state, suppressing turbulent air entrainment. The laminar flow characteristics help reduce the probability of paint particles impacting and accumulating on the surface of the arc-shaped filter plate 14. When it is necessary to clean one of the filters 9 during spraying, close the valves on both sides of the filter 9, open the cover plate 18, and send water into the waste discharge pipe 17. At the same time, start the motor 11. The rotation of the turbine blades 13 can further improve the cleaning effect inside the filter 9.
[0030] The adjusting assembly includes a sealing plug 23 and a screw 28. The sealing plug 23 is rotatably connected to the inner cavity of the mounting base 19. The sealing plug 23 has a first feeding groove 24, a second feeding groove 25, and a third feeding groove 26. A limiting cavity 27 is provided at the top of the sealing plug 23, and a vertical groove is provided on the inner wall of the limiting cavity 27. A threaded groove 21 is provided at the top of the mounting base 19, and the screw 28 is threadedly connected to the threaded groove 21. The bottom end of the screw 28 extends into the limiting cavity 27 and is fixedly connected to a limiting block 29. A protrusion is provided on the limiting block 29, and the protrusion is slidably connected to the vertical groove. A wheel 30 is fixedly connected to the top end of the screw 28. The bottom of the inner cavity of the sealing plug 23 is funnel-shaped. The first feeding groove 24, the second feeding groove 25, and the third feeding groove 26 are all in communication with the inner cavity of the sealing plug 23. The bottom of the inner cavity of the sealing plug 23 is connected to... The bottom of the inner cavity of the mounting base 19 is connected. During operation, when the two filters 9 are being swapped, the operator rotates the wheel 30 to drive the screw 28 to rotate in the threaded groove 21, causing the limit block 29 to drive the sealing plug 23 to rotate. At this time, the protrusion slides in the vertical groove, and the feed channel 24 on the sealing plug 23 rotates accordingly and connects with one of the feed ports 20 corresponding to the filter 9 to be swapped, thus completing the swap of the paint flow path. During this process, the feed channels 25 and 3 are not connected with the feed ports 20. When the two flow paths of the paint need to be cleaned after the spraying is completed, the sealing plug 23 can be rotated to connect the feed channels 25 and 3 26 with the two feed ports 20. At this time, the feed channel 24 is not connected with the two feed ports 20, thus achieving simultaneous rinsing of the flow paths of the two filters 9.
[0031] The mounting base 19 has an annular groove 22 at its top. A limiting ring 31 is rotatably connected within the annular groove 22. Multiple sets of support rods 32 are fixedly connected to the limiting ring 31. The wheel 30 is slidably connected to the support rods 32. A spring 33 is sleeved on the support rod 32. The two ends of the spring 33 are fixedly connected to the bottom end of the wheel 30 and the top of the limiting ring 31, respectively. During operation, when the wheel 30 is rotated, the support rods 32 drive the limiting ring 31 to rotate. At the same time, the wheel 30 slides along the support rods 32 and compresses the spring 33. The elastic potential energy stored in the spring 33 can strengthen the connection between the screw 28 and the threaded groove 21, thereby preventing the screw 28 from loosening during the spraying operation, which would cause the sealing plug 23 to deflect and prevent the paint from being delivered normally.
[0032] The top of the mounting base 19 is fixed with two positioning pins 34, which are respectively adapted to the two feed ports 20. The limiting ring 31 is fixed with three positioning pins 35, which are respectively adapted to the feed groove 24, feed groove 25 and feed groove 26. During operation, the three positioning pins 35 on the limiting ring 31 and the two positioning pins 34 on the mounting base 19 make it easy for the operator to quickly determine the rotation position of the sealing plug 23 when rotating the screw 28.
[0033] Working principle: First, close the valves on branch pipes 1 and 2 on both sides of one filter 9, and open the valves on both sides of the other filter 9. Start the high-pressure pump 3. The paint in the storage tank 2 enters the filter 9 after passing through the feed pipe 7, the three-way pipe 6, and the branch pipe 1 with the valve open. After being filtered by the filter 9, the paint continues to enter the mounting base 19 along the branch pipe 2 with the valve open. Finally, it is drawn from the mounting base 19 into the spray gun 4 by the high-pressure pump 3. The operator can then use the spray gun 4 to complete the spraying work. The turbine blades 13 on the rotating shaft 12 are rotated by the motor 11, so that the periodic flow generated by the rotation of the turbine blades 13 can form a directional scouring effect on the surface of the arc-shaped filter plate 14, destroying the impurity layer adhesion structure formed on the surface of the arc-shaped filter plate 14. When the filter 9 has been used for a certain period of time, close the valves on both sides of the filter 9 that is currently in operation, and open the other filter 9 to achieve non-stop switching. During this period, open the filter to be cleaned. The cover plate 18 on the filter 9 sends water into the waste discharge pipe 17, and the motor 11 is started at the same time. The rotation of the turbine blades 13 can quickly clean the inside of the filter 9. When the two filters 9 are swapped, the operator drives the screw 28 to rotate in the threaded groove 21 by rotating the wheel 30, so that the limit block 29 drives the sealing plug 23 to rotate. At this time, the protrusion slides in the vertical groove, and the feed channel 24 on the sealing plug 23 rotates and connects with one of the feed ports 20 of the filter 9 to be swapped, so as to complete the swap of the paint flow path. During this process, the feed channel 25 and the feed channel 3 26 are not connected to the feed port 20. When the two flow paths of the paint need to be cleaned after the spraying is completed, the sealing plug 23 can be rotated to connect the feed channel 25 and the feed channel 3 26 with the two feed ports 20. At this time, the feed channel 24 is not connected to the two feed ports 20, so that the flow paths of the two filters 9 can be flushed at the same time.
