Description

Technical Field

[0001] The utility model relates to the technical field of vacuum impregnation equipment, in particular to a vacuum impregnation mechanism which is easy to clean. Background Art

[0002] Vacuum impregnation refers to the insulation treatment process in which components or the entire inner stator after assembly and winding connection are impregnated with insulating varnish under vacuum to form a whole. Vacuum pressure impregnation equipment is widely used in the production of high-voltage motors, test transformers, power capacitors, high-voltage cables, etc. It is a key equipment to improve the insulation performance of such products.

[0003] For example, an existing Chinese patent (publication number: CN213279449U) discloses a vacuum impregnation tank. Since the workpiece is lifted up by the apexes of multiple conical top blocks, the contact area of ​​the bottom surface of the workpiece is greatly reduced, and the impregnation effect is improved. When the impregnation is completed, the electric push rod begins to retract, and the movable tray is stably lifted so that it can support the workpiece and move upward. The staff can open the tank cover to take it out, which is easy to use and improves practicality.

[0004] However, the vacuum impregnation tank of the above design still has some disadvantages in practical application: for example, although the vacuum impregnation tank of the above design can improve the effect of impregnating workpieces, it is not convenient to clean the tank. When actually cleaning the tank, it is necessary to inject clean water into the tank and then discharge the liquid through the drain pipe. However, due to the small diameter of the drain pipe, not only is the drainage rate slow, but the drain pipe is also prone to clogging.

[0005] Therefore, we propose a vacuum impregnation mechanism which is easy to clean to solve the above problems. Utility Model Content

[0006] The utility model provides a vacuum impregnation mechanism that is easy to clean. By turning on a motor, a bidirectional screw rod can be rotated so that two nuts drive the L-shaped parts to move away from each other. During this process, the first half tank and the second half tank move away from each other. At this time, the opposite side of the first half tank and the second half tank is in an open state. Then, a person uses a spray gun to flush the first half tank and the second half tank, so that the first half tank and the second half tank can be cleaned. Since the first half tank and the second half tank have larger openings, not only can the drainage rate be increased, but also the problem of blockage can be avoided, thereby solving the problems mentioned in the above background technology.

[0007] In order to solve the above technical problems, the utility model provides a vacuum impregnation mechanism that is easy to clean, including a fixed seat, a first half tank and a second half tank are respectively arranged on both sides of the top of the fixed seat, the first half tank and the second half tank are abutted against each other, a bidirectional screw rod is rotatably arranged in the fixed seat, two nuts are symmetrically threaded on the bidirectional screw rod, a motor is embedded in the fixed seat, the driving shaft of the motor is transmission-connected to one end of the bidirectional screw rod, and the two nuts are respectively connected to the first half tank and the second half tank with a spacing between them.

[0011] Preferably, a material injection pipe is fixedly inserted into one side of the first half tank, and a solenoid valve is arranged at the bottom of the second half tank.

[0012] Preferably, a water inlet is provided on the top of the fixing seat, and a drainage hole is opened on the front side of the fixing seat. The water inlet, the drainage hole and the cavity are connected. The sewage discharged from the first half tank and the second half tank can enter the cavity through the water inlet, and then be discharged to the designated position through the drainage hole. The sewage can be reasonably collected and conveniently treated.

[0013] Preferably, there are multiple water inlets, and the multiple water inlets are opened at equal intervals on the top of the fixing seat, which can further improve the diversion effect.

[0014] Preferably, a sealing ring is fixedly installed on one side of the second half tank, and the sealing ring is against the first half tank. The sealing ring is made of fluororubber, which can improve the sealing between the first half tank and the second half tank.

[0025] In specific implementation, when it is necessary to clean the first half tank 2 and the second half tank 3, the motor 6 is turned on to rotate the bidirectional screw rod 4, so that the two nuts 5 drive the L-shaped part 8 to move away from each other. During this process, the first half tank 2 and the second half tank 3 follow and move away from each other. At this time, the opposite side of the first half tank 2 and the second half tank 3 is in an open state, and then the personnel uses a spray gun to flush the first half tank 2 and the second half tank 3 to clean the first half tank 2 and the second half tank 3. Since the first half tank 2 and the second half tank 3 have larger openings, not only the drainage rate can be increased, but also the problem of blockage can be avoided.

[0026] Embodiment 2

[0027] Depend on Figure 1-3 A vacuum impregnation mechanism which is easy to clean is provided, comprising a fixed seat 1, a first half tank 2 and a second half tank 3 are respectively arranged on both sides of the top of the fixed seat 1, the first half tank 2 and the second half tank 3 are abutted against each other, a bidirectional screw rod 4 is rotatably arranged in the fixed seat 1, two nuts 5 are symmetrically threadedly sleeved on the bidirectional screw rod 4, a motor 6 is embedded in the fixed seat 1, the driving shaft of the motor 6 is transmission connected to one end of the bidirectional screw rod 4, the two nuts 5 are respectively connected to the first half tank 2 and the second half tank 3 with a spacing therebetween, a rotating shaft 11 is rotatably connected in the second half tank 3, a connecting member 12 is fixedly installed on the rotating shaft 11, a scraper 13 is arranged at the other end of the connecting member 12, the scraper 13 is abutted against the inner walls of the first half tank 2 and the second half tank 3, a motor 14 is arranged on one side of the second half tank 3, and the driving shaft of the motor 14 is transmission connected to one end of the rotating shaft 11.

[0028] In the specific implementation, on the basis of Example 1, before flushing the inner walls of the first half tank 2 and the second half tank 3, the motor 14 is turned on to rotate the rotating shaft 11, so that the connecting member 12 drives the scraper 13 to scrape off the materials adhered to the inner walls of the first half tank 2 and the second half tank 3, thereby improving the effect of cleaning the first half tank 2 and the second half tank 3.

[0029] A material injection pipe 15 is fixedly connected to one side of the first half tank 2, and a solenoid valve 16 is provided at the bottom of the second half tank 3. Anti-corrosion materials can be conveniently added and discharged. In addition, when using the vacuum impregnation mechanism, a vacuum pump and an anti-corrosion material storage box should be provided on the first half tank 2 and the second half tank 3. The purpose of the vacuum pump is to make the first half tank 2 and the second half tank 3 in a vacuum state, and the anti-corrosion material storage box is convenient for adding anti-corrosion materials to the first half tank 2 and the second half tank 3, so as to facilitate the impregnation of the workpiece. Since the settings of the vacuum pump and the anti-corrosion material storage box are both existing technologies, they will not be described in detail in this specification.

[0030] In addition, in order to facilitate personnel to control the electrical appliances involved in the vacuum impregnation mechanism, we can also set a controller on the rear side of the fixing seat 1 to control the switch and operation status of the electrical appliances. Since the controller also belongs to the prior art, it will not be explained in detail in this manual.

[0031] A water inlet 17 is provided at the top of the fixing seat 1, and a drainage hole 18 is provided at the front side of the fixing seat 1. The water inlet 17, the drainage hole 18 and the cavity 9 are connected. There are multiple water inlets 17, and multiple water inlets 17 are evenly spaced at the top of the fixing seat 1.

[0032] A sealing ring 19 is fixedly mounted on one side of the second half tank 3, and the sealing ring 19 abuts against the first half tank 2.

[0033] In addition, the solenoid valve 16 is usually a gate valve controlled by an electromagnetic, and the solenoid gate valve can only be fully opened and fully closed. The principle is: when power is turned on, the magnetic valve coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens. When power is turned off, the electromagnetic force disappears, and the spring force presses the closing member onto the valve seat, and the valve closes. Since the valve belongs to the prior art, it will not be explained in detail in this manual.

[0034] Working principle:

[0035] When in use, firstly, all the electrical appliances involved in the vacuum impregnation mechanism are connected to an external power supply. When it is necessary to clean the first half tank 2 and the second half tank 3, the motor 6 is turned on to rotate the bidirectional screw rod 4, so that the two nuts 5 drive the L-shaped parts 8 to move away from each other. In this process, the first half tank 2 and the second half tank 3 move away from each other. At this time, the opposite side of the first half tank 2 and the second half tank 3 is in an open state. Then, the personnel use a spray gun to flush the first half tank 2 and the second half tank 3, so that the first half tank 2 and the second half tank 3 can be cleaned. Since the first half tank 2 and the second half tank 3 have large openings, the first half tank 2 and the second half tank 3 can be cleaned. , which can not only improve the drainage rate but also avoid the problem of clogging. In addition, the sewage discharged from the first half tank 2 and the second half tank 3 can enter the cavity 9 through the water inlet 17, and then be discharged to the designated position through the drainage hole 18. The sewage can be reasonably collected and conveniently treated. It should be noted that before flushing the inner walls of the first half tank 2 and the second half tank 3, the motor 14 is turned on to rotate the rotating shaft 11, so that the connecting member 12 drives the scraping member 13 to scrape off the materials adhered to the inner walls of the first half tank 2 and the second half tank 3, thereby improving the effect of cleaning the first half tank 2 and the second half tank 3.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
