Description

Technical Field

[0001] The invention relates to the technical field of capacitor porcelain sleeve insulator production, in particular to steam heating tunnel drying equipment. Background Art

[0002] The capacitor porcelain sleeve insulator blank is an insulating component used for capacitors, usually made of porcelain. It protects the dielectric and electrodes inside the capacitor, while providing electrical insulation and mechanical support. However, during the production process, the capacitor porcelain sleeve insulator blank needs to use steam heating tunnel drying equipment, mainly to ensure that the product can be evenly heated during the drying process and maintain the stability of product quality and performance;

[0003] Traditional steam-heated tunnel drying equipment usually starts with a steam generator to heat water and gradually convert it into steam. The generated high-temperature steam is transported to the equipment that needs to be heated or the drying tunnel through a pipeline system. At this time, the porcelain sleeve insulator blanks are placed on a conveyor belt in sequence and transported to the tunnel, where they are gradually exposed to high-temperature steam for drying, achieving a gradual drying effect.

[0004] The traditional method has the following problems: since the insulator blanks are placed on the transmission device, some areas may not be evenly exposed to the heating source, resulting in uneven local heating, affecting the quality and performance of the final product. In addition, during transportation in the tunnel, the traditional steam-heated tunnel drying equipment does not have a stable fixing method or track design, which may cause the blanks to fall off or deviate from the correct drying track. For this reason, we propose a steam-heated tunnel drying equipment. Summary of the invention

[0037] The working principle of a steam heating tunnel drying device provided by the present invention is as follows: first, the operation of the steam generator 7 is regulated by the single chip microcomputer 8, and the water is heated and gradually converted into steam by the steam generator 7. The generated high-temperature steam is transported to the steam connecting pipe 2 through the steam connecting pipe 2, and is diverted to the inside of the drying shell 1 through the evenly distributed heating pipes 3, ensuring that the heat can be evenly distributed inside the drying shell 1. Then, the porcelain sleeve insulator blanks are placed on the roller 62 at the right end in sequence, and the operation of the motor 401 is regulated by the single chip microcomputer 8. The output shaft of the motor 401 rotates to drive the screw 410 to rotate. The screw 410 is connected to the mounting block 403 through a thread, so that the mounting block 403 moves along the inner wall of the mounting groove 10 and drives The guide wheel 408 on the mounting seat 404 moves synchronously with the movement of the mounting block 403, so that it can be adjusted according to the height of the porcelain sleeve insulator blank, providing additional guidance during the transmission of the porcelain sleeve insulator blank to prevent it from falling off or shifting during the transmission. At the same time, the operation of the motor 2 61 is regulated by the single-chip microcomputer 8. The rotation of the output shaft of the motor 2 61 drives the rotation of the outermost roller 62. The outermost roller 62 drives the outermost single-groove pulley 64 to rotate, and is transmitted to the adjacent double-groove pulley 63, the adjacent double-groove pulley 63 in the middle, and the innermost single-groove pulley 64 and the adjacent double-groove pulley 63 through the belt 65, so that all the rollers 62 start to rotate. However, the rotation directions of the two motors 2 61 are the same. The porcelain sleeve insulator embryo is ensured to be stable during the transmission process. During the transmission process, the spring 405 between the end of the mounting frame 407 away from the center of the drying shell 1 and the inner side of the adjacent mounting seat 404 can maintain the appropriate distance between the guide wheel 408 and the porcelain sleeve insulator embryo, so that the guide wheel 408 can adaptively move in the slide hole 409 according to the shape and size changes of the embryo, so as to ensure that the embryo is transported along the correct path and remains stable. When the porcelain sleeve insulator embryo is transported to the innermost roller 62 at the right end, it will fall on the support rod 111 between the flip plate 112, and then the high temperature resistant motor 113 is controlled to operate through the single chip microcomputer 8, and the output shaft of the high temperature resistant motor 113 rotates to drive the screw rod 116 to rotate. The screw rod 116 is threadedly connected with the guide block 115, so that the guide block 115 moves to the right along the axis of the limit column 119. The movement of the guide block 115 drives the flip plate 112 to move synchronously, so that the connecting rod 117 starts to rotate with the pin shaft between the flip plate 112 as the center, and rotates and pushes the right end of the flip plate 112 with the pin shaft in the rotating groove as the center. When the right end of the flip plate 112 is pushed, the left end will move along a predetermined trajectory accordingly, and be on the same horizontal line with the innermost roller 62 at the left end, flipping the porcelain sleeve insulator blank and making it fall on the roller 62 at the left end, and being transported to the discharge port, thereby ensuring that the porcelain sleeve insulator blank can evenly cover the entire surface during the heating process in the steam heating tunnel.Avoid quality problems caused by uneven local heating and improve drying effect.
