Description

Technical Field

[0001] The utility model relates to the technical field of control cabinets, in particular to a water-electricity transfer control cabinet for plasma spraying equipment. Background Art

[0002] Plasma spraying technology uses a plasma arc driven by direct current as a heat source to heat ceramics, alloys, metals and other materials to a molten or semi-molten state, and sprays them at high speed onto the pre-treated workpiece surface to form a firmly attached surface layer. During the process of this method, the object needs to be heated by a spray gun, and the internal temperature of the spray gun will gradually increase. Therefore, during use, the spray gun will be cooled by a water-to-electricity conversion device to avoid damage to the spray gun due to long-term high temperature.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] A water-electricity transfer control cabinet for plasma spraying equipment, such as Figure 1-4 As shown, it includes an electric cabinet body 1 and an electrical installation component 2 fixedly installed on the upper end of the electric cabinet body 1;

[0031] A bakelite crossbar 3 is fixedly mounted on the upper end of the electric cabinet body 1, and the bakelite crossbar 3 is located outside the electrical installation assembly 2;

[0032] An electrical installation board 10 is arranged inside the electrical installation assembly 2. The electrical installation board 10 is fixedly installed inside the upper end of the electrical cabinet body 1, and an adjustment structure is fixedly installed just above the electrical installation board 10. Two sets of bakelite fixing blocks 13 are slidably installed inside the adjustment structure, and one set of bakelite fixing blocks 13 is fixedly installed. The two sets of bakelite fixing blocks 13 that are slidably installed are located on both sides of the bakelite fixing blocks 13 that are fixedly installed.

[0033] The outer side of the bakelite fixing block 13 is fixedly installed with a terminal post 14, and the inside of the two sets of bakelite fixing blocks 13 that are slidably installed are fixedly installed with a tungsten rod 17 and a tungsten rod 2 18.

[0034] Combination Figure 5-6 As shown, a fixed wooden board 24 is provided inside the adjustment structure, and the fixed wooden board 24 is fixedly installed on the outside of the electrical installation board 10, and the fixed wooden board 24 is located between the transformer 5 and the high-voltage mica capacitor 7, an insulating screw 25 is rotatably installed inside the fixed wooden board 24, and a moving block 26 is sleeved on the outside of the insulating screw 25, and the moving block 26 is slidably connected to the fixed wooden board 24, two groups of engaging blocks 27 are slidably installed on one end of the moving block 26 away from the fixed wooden board 24, and a supporting spring 28 is fixedly installed on the side where the two groups of engaging blocks 27 are close to each other, and an engaging groove 29 is opened inside the bakelite fixed block 13, and the side of the engaging block 27 away from the moving block 26 is located inside the engaging groove 29.

[0035] Before using the control cabinet, it is necessary to adjust the distance between tungsten rod 17 and tungsten rod 2 18, and during the adjustment process, the insulating screw 25 needs to be rotated. During the rotation of the insulating screw 25, the two groups of moving blocks 26 threadedly connected thereto will move in opposite directions inside the fixed wooden board 24, and the moving blocks 26 will drive the tungsten rod 17 and tungsten rod 2 18 to move during the movement, thereby changing the distance between tungsten rod 17 and tungsten rod 2 18, thereby achieving the effect of changing the breakdown voltage. The breakdown voltage is adjusted by rotating the insulating screw 25, which effectively improves the effect of adjusting the breakdown voltage of the control cabinet.

[0036] Based on the above embodiments, Figure 1-Figure 4 As shown, the water inlet joint 11 is located at the lower end of the pressure gauge 9, the lower end of the return water joint 12 is connected to the water tank water inlet joint 16, and the lower end of the water inlet joint 11 is connected to the water tank water outlet joint 15;

[0037] A coil 19 is arranged on the outside of the electrical installation board 10 , and the two ends of the coil 19 are connected to the return water joint 12 and the reverse water cable joint 21 respectively, and a spray gun 23 is fixedly installed at the lower ends of the positive water cable joint 22 and the reverse water cable joint 21 .

[0038] When the spray gun 23 connected inside the electric cabinet body 1 is used, the spray gun 23 will generate a large amount of heat and increase its internal temperature. At this time, the water flow inside the electric cabinet body 1 will cool down the spray gun 23 through circulation, thereby achieving the effect of protecting the spray gun 23.

[0039] Specifically, in the process of water flow cooling the spray gun 23, the cooling water flows out from the water tank outlet joint 15 of the ice water filter, and then flows into the high-pressure water pipe, enters the interior of the copper block welding body 20 through the water inlet joint 11, and then passes through the positive-tooth water cable joint 22, and is connected to the anode of the spray gun 23 through the water cable. At this time, the cooling water can enter the interior of the spray gun 23 and absorb the heat inside the spray gun 23; and after the cooling water circulates inside the spray gun 23, its internal temperature will increase, and the heated water will flow back from the cathode of the spray gun 23, and be connected to the reverse-tooth water cable joint 21 through the water cable, and finally be connected to the return joint 12 of the ice water filter through the coil 19 and the return water joint 12. The high-pressure water pipe is connected to the ice water filter integrated machine. At this time, the hot water can enter the interior of the ice water filter integrated machine, thereby completing the internal water flow circulation process of the control cabinet and effectively cooling the spray gun 23.

[0040] It is worth mentioning that the control cabinet as a whole in this embodiment is not only easy to carry and use, but can also be used alone with an external ice water filter integrated machine to complete the cooling effect on the spray gun 23. The external ice water filter integrated machine and the spray gun 23 are connected to the structure inside the electric cabinet body 1 through a high-pressure pipeline, which is convenient for the disassembly and assembly of the spray gun 23, and the control cabinet is convenient for storing the spray gun 23. By installing the electrical installation component 2 inside the electric cabinet body 1, the structure is effectively integrated, which improves the convenience of using the modular structure and increases the overall practicality.
