Description

Technical Field

[0001] This utility model relates to the field of AC filter technology, specifically to an AC filter insulation coating device. Background Technology

[0002] In DC transmission systems, in order to filter out harmonics generated by the DC control system to avoid adverse effects on the AC transmission system, and to compensate for the reactive power consumed by the DC control system, a certain number of AC filters must be put into operation during the DC system operation. Insulating coating, as a workpiece surface treatment technology, is often used in the production and processing of AC filters. By coating the surface of the AC filter housing with a layer of insulating material, the overall insulation performance and corrosion resistance of the AC filter can be effectively improved.

[0003] Existing AC filter insulation coating devices typically require coating the outer and inner surfaces of the AC filter housing separately. However, due to the lack of a mechanism that can simultaneously coat both the outer and inner surfaces of the AC filter housing, workers must manually adjust the AC filter housing after completing the coating of one side before coating the other side. This reduces the coating efficiency of the AC filter housing to some extent and is not conducive to the AC filter insulation coating process. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 As shown, an AC filter insulation coating device includes a base 1, a processing box 2 fixedly mounted on the top of the base 1, a processing platform 4 on the top of the inner cavity of the processing box 2, and a filter housing 5 on the top of the processing platform 4; a U-shaped frame 6, positioned above the filter housing 5, with a quadrilateral frame 3 fixedly connected to the top edge of the processing box 2, and a lifting component 7 on the top of the quadrilateral frame 3 for adjusting the height of the filter housing 5. By setting the lifting component 7, the processing platform 4 and the filter housing 5 on top can be moved to different positions within the processing box 2, thereby facilitating the subsequent coating work of the filter housing 5; and a liquid storage tank 11, fixed to the bottom of the processing box 2. Inside the processing box 2, a coating component 10 is provided to simultaneously spray the inner and outer surfaces of the filter housing 5 to improve the overall processing efficiency. By setting the coating component 10, insulation coating treatment can be performed on both sides of the filter housing 5 simultaneously, which is beneficial to improving the overall coating efficiency of the filter housing 5 compared to the common method of coating only one side of the filter housing 5 at the same time.

[0026] The coating assembly 10 includes an inner annular tube 106 at the bottom of the filter housing 5, an outer annular tube 105 on the outer side of the bottom end of the filter housing 5, the outer annular tube 105 being located above the processing platform 4, and second nozzles 107 intermittently and equally spaced on both the side of the outer annular tube 105 near the filter housing 5 and the side of the inner annular tube 106 near the filter housing 5. A lower strip tube 102 is located inside the inner annular tube 106, and an upper strip tube 101 is located below the U-shaped frame 6, above the quadrilateral frame 3. Multiple distribution tubes 103 are symmetrically installed on both sides of the upper strip tube 101 and both sides of the lower strip tube 102. First nozzles 104 are intermittently and equally spaced on the side of the distribution tubes 103 near the filter housing 5. Figure 4 , Figure 5 and Figure 6 As shown, when coating the filter housing 5, the filter housing 5 can be placed on top of the processing platform 4 beforehand. At the same time, it is necessary to ensure that the filter housing 5 is located between the inner annular tube 106 and the outer annular tube 105. Then, the lifting component 7 is used to drive the filter housing 5 to slowly fall and gradually enter the interior of the processing box 2. During this process, the second nozzles 107 on the outer side of the inner annular tube 106 and the outer annular tube 105 will coat the insulating coating on the inner and outer walls of the filter housing 5 along the way. After the filter housing 5 has completely entered the interior of the processing box 2, the first nozzles 104 on the distribution pipe 103 on the outer side of the lower strip tube 102 and the upper strip tube 101 can be used to coat the insulating coating on the top of the inner cavity and the top surface of the filter housing 5 respectively. This allows for simultaneous insulation coating treatment on both sides of the filter housing 5, which helps to improve the overall coating efficiency of the filter housing 5.

[0027] A first liquid pump 12 is fixedly installed at the bottom of the liquid storage tank 11. The inlet of the first liquid pump 12 is connected to the inside of the liquid storage tank 11, and the outlet of the first liquid pump 12 is connected to a first outlet pipe 13. The top end of the first outlet pipe 13 passes through the processing platform 4 and connects to the outer annular pipe 105. A second outlet pipe 14 is connected to the bottom of one side of the inner annular pipe 106. The bottom end of the second outlet pipe 14 passes through the processing platform 4 and connects to the first outlet pipe 13. A first liquid pump 12 is fixedly installed at the top of one side of the liquid storage tank 11. A second liquid pump 15 is installed, with its inlet connected to the inside of the storage tank 11. The outlet of the second liquid pump 15 is connected to a third outlet pipe 16. The top end of the third outlet pipe 16 passes through the processing platform 4 and connects to the lower strip pipe 102. The top of the upper strip pipe 101 is connected to a fourth outlet pipe 18. One end of the fourth outlet pipe 18 extends to the outside of the quadrilateral frame 3 and is fixedly connected to a telescopic hose 17. The bottom end of the telescopic hose 17 is connected to the third outlet pipe 16. Figure 2 , Figure 3 and 4 As shown, the first liquid pump 12 can be used to input the insulating coating inside the liquid storage tank 11 into the outer annular pipe 105 and the inner annular pipe 106 through the first liquid outlet pipe 13 and the second liquid outlet pipe 14, respectively. The second liquid pump 15 can be used to input the insulating coating inside the liquid storage tank 11 into the upper strip pipe 101 and the lower strip pipe 102 through the third liquid outlet pipe 16, the telescopic hose 17 and the fourth liquid outlet pipe 18, respectively. In this way, the insulating coating is continuously supplied to the coating assembly 10, which is beneficial to the insulation coating work of the filter housing 5.

[0028] A drain port 20 is located at the bottom of one side of the treatment tank 2, and a liquid inlet 19 is located at the top of one side of the storage tank 11. Both the liquid inlet 19 and the drain port 20 are equipped with solenoid valves. Figure 2 , Figure 4 As shown, the external insulating coating can be easily introduced into the liquid storage tank 11 through the liquid injection port 19, and the sewage discharge port 20 can be used to facilitate the discharge of cleaning wastewater when the staff is cleaning the inside of the treatment tank 2, thereby improving its practicality.

[0029] The lifting assembly 7 includes first L-shaped plates 71 fixed to the top of both sides of the quadrilateral frame 3. A first hydraulic cylinder 73 is fixedly installed on each side of the two first L-shaped plates 71 that are far apart from each other. Second L-shaped plates 72 are provided on both sides of the U-shaped frame 6. The bottom end of the second L-shaped plate 72 is connected to the processing platform 4. The top end of the first hydraulic cylinder 73 passes through the first L-shaped plate 71 and connects to the second L-shaped plate 72. Figure 1 , Figure 2 and Figure 4As shown, the first hydraulic cylinder 73 and the second L-shaped plate 72 can drive the processing platform 4 and its top filter housing 5 to slowly fall and reach different positions inside the processing box 2, thereby facilitating the subsequent coating work of the filter housing 5.

[0030] A support plate 8 is provided above the U-shaped frame 6. The support plate 8 is connected to the second L-shaped plates 72 at both ends. A second hydraulic cylinder 9 is fixedly installed at the top of both ends of the support plate 8. The bottom end of the second hydraulic cylinder 9 passes through the support plate 8 and is connected to the U-shaped frame 6. Figure 3 , Figure 4 As shown, by setting the second hydraulic cylinder 9, the U-shaped frame 6 can be raised as a whole when the filter housing 5 is placed, so as to prevent the U-shaped frame 6 from obstructing the placement of the filter housing 5. At the same time, after the filter housing 5 reaches the interior of the processing box 2, the second hydraulic cylinder 9 can be used to drive the upper strip tube 101 below the U-shaped frame 6 to move closer to the filter housing 5, so as to facilitate the coating work of the filter housing 5.

[0031] The processing platform 4 has intermittently spaced liquid guide ports 21 for excess paint to drip off, such as... Figure 6 As shown, by setting the liquid guide port 21, excess insulating paint can be easily dripped from the liquid guide port 21 to the bottom of the inner cavity of the processing box 2 during the coating work of the filter housing 5, thereby avoiding the paint from staying on the top of the processing platform 4 for a long time and affecting the insulation coating work of the filter housing 5.

[0032] Working principle: First, the operator can place the filter housing 5 on the top of the processing platform 4, while ensuring that the filter housing 5 is located between the inner annular tube 106 and the outer annular tube 105. Then, the lifting component 7 can drive the processing platform 4 and the filter housing 5 on top to slowly fall to different positions in the processing box 2, which facilitates the subsequent coating work of the filter housing 5. Then, the coating component 10 applies insulating coating to the inner and outer walls of the filter housing 5 along the way, realizing the simultaneous insulation coating treatment of both sides of the filter housing 5. Compared with the common method of coating only one side of the filter housing 5 at the same time, it is beneficial to improve the overall coating efficiency of the filter housing 5.
