Description

Technical Field

[0001] This utility model relates to the technical field of drying devices, and in particular to a drying device for impregnating and drying explosion-proof motor windings. Background Technology

[0002] The impregnation and drying process is a key step in the manufacturing of explosion-proof motor windings. Through impregnation, the varnish can fully penetrate between the winding turns and between the insulation layer and the conductor, filling the tiny pores of the insulation material and forming a uniform and dense insulating protective layer.

[0003] Currently, in the process of impregnating and drying windings, such as the patent with prior art authorization announcement number CN208112466U, this utility model provides a motor stator winding impregnation and drying device, which solves the technical problems of complex structure and poor drying effect of existing motor stator winding impregnation and drying devices. It is equipped with a workbench, a drying box above the workbench, a vacuum tube connected to the bottom of the drying box, a vacuum pump inside the workbench, and the suction pipe end of the vacuum pump is connected to the vacuum tube through a solenoid valve.

[0004] However, it was found during the use of the device that it was not very effective at drying the inside of the windings, which reduced the efficiency of the winding drying process and the convenience of use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an explosion-proof motor winding impregnation and drying device that uses multiple sets of nozzles to blow air and dry the outside of the winding, while simultaneously using air jet pipes to blow air and dry the inside of the winding, thereby driving the winding to rotate and improving the efficiency and uniformity of the drying process.

[0006] This utility model discloses an explosion-proof motor winding impregnation and drying device, comprising a housing with an opening at the front end; it also includes a support device, a support mesh plate, a U-shaped air duct, nozzles, and an air jet pipe. The support mesh plate is disposed inside the housing, the U-shaped air duct is installed on the inner side wall of the housing, multiple sets of nozzles are connected and disposed on the U-shaped air duct, and the air jet pipe is disposed inside the housing via the support device. The support device is used to support and fix the winding and to drive the winding to move and adjust. Both the U-shaped air duct and the air jet pipe are connected to an external hot air device. The impregnated winding is placed on top of the support mesh plate, and then the air jet pipe is moved downward by the support device to extend into the winding. The winding is then clamped and fixed by the support device, and then the winding is moved upward by the support device to be in a suspended state. Hot air is delivered to the U-shaped air duct and the air jet pipe by the external hot air device, so that the multiple sets of nozzles blow air to dry the outside of the winding, while the air jet pipe blows air to dry the inside of the winding. At the same time, the support device drives the winding to rotate, thereby improving the drying efficiency and uniformity of the winding.

[0007] Preferably, the support device includes a lifting device, a driving device, a housing, a cylinder, a guide member, a clamping member, and a first hydraulic cylinder. The housing is installed on the inner wall of the box via the lifting device, and the cylinder is rotatably installed at the bottom of the housing via the driving device. An electromagnetic slip ring is provided between the housing and the cylinder. The guide member is installed at the bottom of the cylinder, and two sets of clamping members are slidably installed on the guide member. Two sets of first hydraulic cylinders are installed on the outer wall of the guide member, and the moving ends of the two sets of first hydraulic cylinders are connected to the outer walls of the two sets of clamping members. The top end of the jet pipe is installed on the inner wall of the housing, and the lower part of the jet pipe passes through the cylinder and the inside of the guide member. When the winding is placed on the support mesh plate, the lifting device drives the housing to move downward, causing the housing to drive the two sets of clamping members to extend into the winding. The two sets of first hydraulic cylinders drive the two sets of clamping members to move away from each other, thereby causing the two sets of clamping members to expand and clamp the winding. At this time, the jet pipe extends into the winding simultaneously, suspending the winding. Then, the driving device drives the cylinder to rotate, thereby causing the two sets of clamping members to drive the winding to rotate for drying.

[0008] Preferably, the driving device includes a motor, a gear, and a gear ring. The motor is mounted on the inner side wall of the housing, the gear is located on the output end of the motor, and the gear ring is mounted on the outer side wall of the cylinder. The gear meshes with the gear ring. The motor drives the gear to rotate, which in turn drives the cylinder to rotate through meshing with the gear ring.

[0009] Preferably, the lifting device includes a first guide rail and a second hydraulic cylinder. The first guide rail is installed on the inner side wall of the housing, and the housing is slidably installed on the first guide rail. The second hydraulic cylinder is installed on the inner side wall of the housing, and the moving end of the second hydraulic cylinder is connected to the housing. The second hydraulic cylinder drives the housing to move up and down, improving the convenience of suspending and rotating the winding.

[0010] Preferably, it also includes a collection trough, which is located at the bottom of the box body; by providing a collection trough, it is convenient to collect excess dripping paint.

[0011] Preferably, it also includes a second guide rail, which is disposed on the inner side wall of the housing, and the support mesh plate is slidably mounted on the second guide rail; this improves the convenience of pulling and sliding the support mesh plate outward and improves the convenience of picking up and placing the winding on the support mesh plate.

[0012] Preferably, it also includes a sealing door, which is installed at the opening of the housing; this improves the sealing effect of the housing and increases the drying efficiency of the hot air on the windings.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the varnished winding is placed on the top of the support mesh plate, and then the air jet pipe is moved downward by the support device so that the air jet pipe extends into the winding. Then the winding is clamped and fixed by the support device. Then the winding is moved upward by the support device so that the winding is in a suspended state. Hot air is delivered to the U-shaped air duct and the air jet pipe by the external hot air equipment, so that multiple sets of nozzles blow air to dry the outside of the winding, while the air jet pipe blows air to dry the inside of the winding. At the same time, the winding is rotated by the support device, thereby improving the drying efficiency and the uniformity of the drying process. Attached Figure Description
