Description

Technical Field

[0001] The utility model relates to the technical field of rust removal, in particular to a valve seat rust removal device. Background Art

[0002] Rust is a general term for iron oxides, usually red in color, generated by the oxidation-reduction reaction between iron and oxygen. Different forms of rust are generated under different circumstances, and most valve seats are made of iron. After long-term use, rust often forms on the surface of the valve seat, which makes the valve seat unusable. In order to extend the life of the valve seat, the valve seat needs to be derusted.

[0003] Most rust removal is done manually, using handheld tools to mechanically cut away the rust on the valve seat surface, or using chemical solutions for natural decomposition. However, these methods are either time-consuming or labor-intensive, and most valve seats have simple structures. When large quantities of valve seats need to be rusted, these rust removal methods are less efficient. Utility Model Content

DETAILED DESCRIPTION

[0020] 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 of the embodiments.

[0021] Reference Figure 1-5A valve seat rust removal device comprises a base 1, a plurality of support structures 3 are symmetrically arranged on the upper surface of the base 1, a motor 2 is arranged on the upper surface of the base 1 and located on one side of the support structure 3, rust removal buckets 4 are rotatably arranged on the support structures 3 on both sides, a side wall of one side of the rust removal bucket 4 is fixedly connected to the output end of the motor 2, and a cover plate 5 is arranged on the rust removal bucket 4;

[0022] The rust removal bucket 4 has a cover plate 5 at the middle opening of the barrel body, and the cover plate 5 is fixed by a fixing component 6. A cavity 43 is provided in the rust removal bucket 4, and the rust removal bucket 4 has lower fixing plates 42 at both sides of the barrel body and the opening.

[0023] Among them, a circle of wheel grooves 41 are opened on the outer wall of the rust removal bucket 4 and on both sides of the opening, and the wheel grooves 41 are against the supporting structures 3 on both sides. Grooves 44 are symmetrically provided on the sides of the opening of the rust removal bucket 4. The wheel grooves 41 facilitate the supporting structure 3 to support the rust removal bucket 4.

[0024] In addition, the cover plate 5 has an arc-shaped body, and upper fixing plates 51 are symmetrically fixedly connected on both sides of the cover plate 5. A sealing gasket 52 is attached to the bottom surface of the cover plate 5, and silicone strips 54 are attached to the arc side walls on both sides of the cover plate 5. Pinching blocks 53 are symmetrically arranged on both sides of the upper surface of the cover plate 5. The pinching blocks 53 are convenient for the operator to pinch and thereby pick up the cover plate 5.

[0025] Moreover, the upper fixing plate 51 and the lower fixing plate 42 correspond in position, and the upper fixing plate 51 and the lower fixing plate 42 can be horizontally fitted together and passed through by the fixing component 6. The upper fixing plate 51 and the lower fixing plate 42 are both provided with threaded holes that engage with the fixing component 6. The upper fixing plate 51 and the lower fixing plate 42 are convenient for installing the fixing component 6 to buckle and fix the cover plate 5 on the rust removal bucket 4.

[0026] Meanwhile, the support structure 3 comprises a rotating seat 31 on which a roller 32 is rotatably arranged. The roller 32 can rotate in the wheel groove 41 . The roller 32 can play the role of auxiliary rotating support when the motor 2 drives the rust removal bucket 4 to rotate.

[0027] In addition, when the cover plate 5 is buckled and fixed on the opening of the rust removal bucket 4, the fixing component 6 is inserted into the lower fixing plate 42 and the upper fixing plate 51, and the sealing gasket 52 is fitted in the groove 44. The sealing gasket 52 can prevent most of the rust removal sand from leaking out.

[0028] In this embodiment, when it is necessary to remove rust from the rusted valve seat, the present device can be used. First, the cover plate 5 is separated from the rust removal bucket 4, and then a certain number of valve seats are placed into the cavity 43, and then rust removal sand is poured into the cavity 43, and then a certain amount of rust remover is sprayed, and then the cover plate 5 is covered on the opening of the rust removal bucket 4, and after the lower fixing plate 42 and the upper fixing plate 51 are aligned, the fixing component 6 is used to screw over the lower fixing plate 42 and the upper fixing plate 51, and then the cover plate 5 is fixed on the rust removal bucket 4.

[0029] At the same time, the sealing gasket 52 fits in the groove 44 to prevent most of the rust removal sand from leaking out, and the silicone strip 54 is flexible, so that the cover plate 5 can be better clamped at the opening of the rust removal bucket 4.

[0030] After the cover plate 5 is fixed, the motor 2 can be started, so that the rust removal bucket 4 fixed on the output end of the motor 2 can rotate synchronously with the output end of the motor 2, and the roller 32 below cooperates with the rotating seat 31 to rotate in the wheel groove 41, playing a role of auxiliary support, and the internal valve seat will roll with the rust removal bucket 4 together with the rust removal sand to perform roller polishing and rust removal. After a period of roller polishing and rust removal, the rust layer on the valve seat can be removed, and then the cover plate 5 can be opened.

[0031] When opening the cover plate 5 , all the fixing components 6 are removed, and then the pinching block 53 is pinched to lift the cover plate 5 , so that the valve seat in the cavity 43 after rust removal can be collected.

[0032] In the utility model, the rust removal bucket 4 is driven by the motor 2 to roll on the support structure 3, and the rusted valve seat and rust removal sand are placed in the cavity 43. The rolling rust removal bucket 4 allows the valve seat to be rolled and rust removed with the rust removal sand, and the cover plate 5 is convenient for sealing the rust removal bucket 4. At the same time, when disassembly or installation is required, the installation or disassembly method is relatively convenient. At the same time, multiple valve seats can be placed in the cavity 43 at one time, so that multiple valve seats can be derusted at one time, and manual rust removal is not required, thereby improving the efficiency of rust removal.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
