Abstract
Description
Technical Field
[0001] This utility model relates to the field of shot blasting processing technology, specifically a shot blasting device for iron parts of dry-type transformers. Background Technology
[0002] Shot blasting of iron components in dry-type transformers is a surface treatment process mainly used to clean and strengthen the surface of iron parts, improving their performance and adaptability to subsequent processing. It primarily utilizes a high-speed rotating impeller in shot blasting equipment (such as a shot blasting machine) to propel abrasive materials such as steel shot and steel grit at a speed of 50–100 meters per second onto the surface of iron components (such as the core, clamps, and supports) of the dry-type transformer. The treatment is achieved through the impact and cutting action of the abrasive materials.
[0003] In shot blasting of transformer iron components, steel shot is the mainstream choice. Its materials include steel (such as carbon steel and stainless steel), cast iron, and ferroalloys. These materials contain a large number of iron atoms with orderly internal electron spins, which can be strongly attracted by magnets. Steel shot generally needs to be recycled and reused after use. Steel shot that has been used multiple times may break and fragment into smaller metal residues due to metal fatigue. These metal residues are often mixed with the better steel shot, which makes it more difficult to separate the better steel shot from the metal residues.
[0004] To address these issues, this invention provides a shot blasting device for iron components of dry-type transformers. Utility Model Content

[0017] Beneficial effects
[0018] This utility model provides a shot blasting treatment device for iron components of dry-type transformers. Compared with the prior art, it has the following advantages:
[0019] 1. This shot blasting device for dry-type transformer iron parts can control the L-shaped baffle to move upward and open by starting the electric push rod. Then, the transformer iron parts to be processed can be placed into the installation box by the feeding device or the loading machine, which is fixed on the fixture. Then, the shot blasting machine can be started to process the transformer iron parts. The entire processing is carried out in the installation box, which can effectively reduce the spread of dust.
[0020] 2. In this shot blasting device for iron components of dry-type transformers, some broken steel shot residues are mixed with relatively intact steel shot and fall into a collection box through a funnel box. During the falling process of the steel shot and residues, an electromagnet can be activated. The magnetic force generated by the electromagnet can attract the smaller residues to its surface, while the larger steel shot can escape the magnetic attraction during the falling process and fall onto the inclined surface at the bottom of the collection box. After sliding down the inclined surface, it falls from the bottom outlet of the collection box, thus recovering the relatively intact steel shot. By pushing the pull rod, the push plate slides on the inclined surface at the bottom of the collection box, thereby scraping away any remaining metal residues. This process compresses the spring and then releases the pull rod, allowing the spring to release its elasticity and reset the pull rod through the separator ring. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0030] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0031] Reference Figures 1 to 6 This application provides a shot blasting device for dry-type transformer iron parts, including a mounting box 1, with a processing component 2 inside the mounting box 1; a recovery component 3 is provided at the bottom of the mounting box 1; the recovery component 3 includes a funnel box 31, with a collection box 32 fixedly connected to the bottom of the funnel box 31, an electromagnet 33 slidably connected to the inside of the side wall of the collection box 32, a connecting plate 34 fixedly connected to one end of the electromagnet 33, and a handle 35 fixedly connected to one side of the connecting plate 34. An auxiliary block 36 is fixedly connected to one side of the collection box 32, and the auxiliary block 36 can be inserted into one end of the electromagnet 33. A pull rod 39 is slidably connected to the inside of the side wall of the collection box 32, with a push plate 37 fixedly connected to one end of the pull rod 39, and the push plate 37 is slidably connected to the bottom inclined surface of the collection box 32. One end of the pull rod 39 is fixedly connected to a partition ring 310, one side of the central box 32 is fixedly connected to a sleeve 38, one side of the partition ring 310 is fixedly connected to a spring 311, one end of the spring 311 is fixedly connected to one side of the central box 32, and the pull rod 39 and the spring 311 are located inside the sleeve 38.
[0032] In this embodiment, some broken steel shot residue is mixed with relatively intact steel shot and falls into the collection box 32 through the funnel box 31. During the falling process of the steel shot and residue, the electromagnet 33 can be activated. The magnetic force generated by the electromagnet 33 can attract the smaller residue to its surface, while the larger steel shot can escape the magnetic attraction during the falling process and fall onto the inclined surface at the bottom of the collection box 32. After sliding down the inclined surface, it falls from the bottom outlet of the collection box 32, thus recovering the relatively intact steel shot. By pushing the pull rod 39, the push plate 37 slides on the bottom inclined surface of the collection box 32, thereby scraping away any remaining metal residue. This process compresses the spring 311 and then releases the pull rod 39. The spring 311 can then release its elasticity and reset the pull rod 39 through the separator ring 310. When it is necessary to repair the electromagnet 33, it can be pulled out directly through the handle 35. The auxiliary block 36 can provide support for the other end of the electromagnet 33.
[0033] Reference Figures 1 to 6 In one aspect of this embodiment, the processing assembly 2 includes a frame rod 21, with a shot blasting machine 22 fixedly mounted at one end of the frame rod 21. A limiting block 24 is fixedly connected to one side of the mounting box 1, and an L-shaped baffle 25 is slidably connected between the limiting block 24 and the mounting box 1. An electric push rod 23 is fixedly connected to one side of the mounting box 1, and the movable end of the electric push rod 23 is fixedly connected to the top of the L-shaped baffle 25.
[0034] In this embodiment, by activating the electric actuator 23, the L-shaped baffle 25 can be controlled to move upward and open. Then, the transformer iron parts that need to be processed, which are fixed on the fixture, can be placed into the mounting box 1 by the feeding device or the loading machine. Then, the shot blasting machine 22 can be started to process the transformer iron parts. The entire processing process is carried out within the mounting box 1, which can effectively reduce the spread of dust.
[0035] Working principle: During equipment operation, the L-shaped baffle 25 can be opened by activating the electric actuator 23. Subsequently, with the help of the feeding device or loader, the iron transformer part to be processed, fixed on the fixture, is accurately fed into the mounting box 1. Then, the shot blasting machine 22 is started to process the iron part. Since the entire processing is carried out in the closed mounting box 1, dust diffusion is effectively suppressed, reducing dust pollution.
[0036] After processing, the broken steel shot residue and intact steel shot fall together through the funnel box 31 into the collection box 32. During the descent, the electromagnet 33 is activated, and the magnetic force it generates attracts the lighter residue to the surface, while the intact steel shot, due to its greater mass, escapes the magnetic attraction and slides down the inclined surface at the bottom of the collection box 32, falling out of the outlet, achieving efficient recycling. After recycling is complete, the pull rod 39 is pulled, causing the push plate 37 to slide on the inclined surface at the bottom of the collection box 32, thoroughly removing any remaining metal residue. This process compresses the spring 311. After releasing the pull rod 39, the spring 311 releases its elasticity, and the pull rod 39 returns to its original position through the separator ring 310, preparing for the next recycling and cleaning cycle.
