Description

Technical Field

[0001] The invention relates to the technical field of gas relays, and in particular to a material processing method and processing equipment for gas relays. Background Art

[0002] A gas relay (also known as a gas relay) is a protective device used in transformers. It is installed in the pipeline between the oil storage cabinet and the oil tank of the transformer. When an internal fault of the transformer causes the oil to decompose and produce gas or causes oil flow to surge, the contacts of the gas relay are activated, the specified control circuit is connected, and a signal alarm is issued in time or the protection element is activated to automatically cut off the transformer. The double float baffle gas relay is a device used to monitor and control gas flow. It uses two internal floats and a baffle to accurately measure and control the gas flow rate and pressure. The device has important application value in the safe production of high-risk places such as coal mines, oil fields, and petrochemicals.

[0003] The existing gas relay is in contact with insulating oil. When the transformer fails, overheats or generates an arc, the insulating oil decomposes to produce acidic substances such as formic acid (HCOOH) and acetic acid (CH3COOH). If the insulating oil contains sulfur, hydrogen sulfide may be released during decomposition. This gas is corrosive and toxic, and may decompose into corrosive aldehyde compounds such as formaldehyde (HCHO), causing corrosion of various parts in the gas relay, especially the float, which is more severely corroded and cannot provide sufficient buoyancy for the gas relay, causing the gas relay to fail to work normally, which is easy to cause safety accidents. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the prior art that when a transformer fails, overheats or generates an arc, the insulating oil decomposes into corrosive substances, causing corrosion of various parts in the gas relay, especially the float, and causing the gas relay to fail to work normally. A material processing method and processing equipment for a gas relay are proposed to solve the problems in the prior art that when a transformer fails, overheats or generates an arc, the insulating oil decomposes into corrosive substances, causing corrosion of various parts in the gas relay, especially the float, and causing the gas relay to fail to work normally.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] S6. Move the storage tray to the paint spraying device and spray corrosion-resistant paint on the float;

[0040] S7, stacking the trays at intervals and conveying them to a drying device for drying.

[0041] In the present invention, the float is ground and polished to remove oxides and dirt on the surface of the float, making the surface smoother and reducing surface unevenness, thereby reducing the aggregation of corrosive substances and increasing adhesion to corrosion-resistant paint, thereby improving the corrosion resistance effect.

[0042] Reference Figure 1-5 The present invention further proposes a material processing device for a gas relay and a material processing method for the above-mentioned gas relay, comprising a processing table 1, on which a grinding mechanism 2 and a polishing mechanism 3 are arranged, a turntable 4 is arranged on the processing table 1, and a plurality of workstations 5 for placing material trays are arranged on the turntable 4, and a positioning structure 6 is arranged on each workstation 5, and a reduction motor for driving the turntable 4 to rotate is arranged in the processing table 1.

[0043] Furthermore, in this embodiment, a guide column 7 is provided on the processing table 1 to cooperate with the grinding mechanism 2 and the polishing mechanism 3, and a height adjustment mechanism 8 is provided in the guide column 7 to drive the grinding mechanism 2 and the polishing mechanism 3 to move. The positions of the grinding mechanism 2 and the polishing mechanism 3 are controlled by the height adjustment mechanism 8, which facilitates the grinding and polishing of the float on the loading plate, and at the same time will not hinder the turntable 4 from driving the loading plate to rotate.

[0044] Furthermore, in the present embodiment, the height adjustment mechanism 8 includes a guide groove 81 provided on the guide column 7, and the grinding mechanism 2 and the polishing mechanism 3 are both fixedly provided with a guide portion 82 which is slidably connected to the guide groove 81. By providing the guide portion 82 to cooperate with the guide groove 81, the moving trajectory of the grinding mechanism 2 and the polishing mechanism 3 is limited to prevent them from being misaligned with the loading plate.

[0045] In this embodiment, a servo motor is fixedly installed in the guide groove 81, and the output shaft of the servo motor is fixedly connected to the screw rod 83. A nut seat threadedly connected to the screw rod 83 is fixedly installed on the guide part 82. The screw rod 83 is driven to rotate by the servo motor, and the nut seat and the guide part 82 are driven to move up and down, thereby controlling the position of the grinding mechanism 2 and the polishing mechanism 3.

[0046] It should be noted that, in this embodiment, a guide rod 84 is fixedly provided on the processing table 1, and the guide rod 84 is movably connected with the guide portion 82, so that the force exerted on the guide portion 82 is shared by the guide rod 84, thereby preventing the guide portion 82 from bending due to excessive force.

[0049] In this embodiment, a support assembly 9 is provided in the work station 5, and the upper end of the support assembly 9 abuts against the placement tray. An upward force is applied to the placement tray through the support assembly 9. When the positioning structure 6 cancels the fixation of the placement tray, the support assembly 9 lifts the placement tray and separates it from the work station 5, making it convenient to take out the placement tray for replacement.

[0051] Working mode: When working, the turntable 4 is driven to rotate by the reduction motor, and the carrier plate is transported to the grinding mechanism 2 and the polishing mechanism 3, so that the floating ball on the carrier plate is ground and polished;

[0052] Before processing, the servo motor controls the screw rod 83 to drive the guide part 82 upward, thereby driving the grinding mechanism 2 and the polishing mechanism 3 to move upward, so as not to hinder the rotation of the turntable 4. When the loading plate is delivered to the right position, the grinding mechanism 2 and the polishing mechanism 3 are controlled to move downward to grind and polish the float.
