Description

Technical Field

[0001] This utility model relates to the field of steel processing technology, and in particular to an H-beam shot blasting and dust removal device. Background Technology

[0002] During the processing of H-beams, shot blasting machines can remove oxide scale, rust, oil stains and other contaminants from the surface of the H-beams, so as to expose the steel substrate and provide a clean surface for subsequent surface treatment processes such as painting and electroplating.

[0003] However, during the process, dirt and rust on the surface of the H-beams are removed by high-speed projectiles, which also generate a large amount of dust and debris. If this dust and debris is not removed in time, it can easily spread in the air, which is not only detrimental to the environment, but also poses a threat to the respiratory health of workers.

[0004] Based on the above situation, the inventors have proposed an H-beam shot blasting and dust removal device to improve the situation. Utility Model Content

[0032] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] This utility model embodiment specifically provides an H-beam shot blasting suction dust removal device. Please refer to... Figures 1-4 It includes a shot blasting machine 1, a dust removal assembly 2, and a dust collection pipe 3.

[0034] The shot blasting machine 1 and the dust removal component 2 are connected by a dust collection pipe 3. Flexible baffles are provided at both ends of the working chamber of the shot blasting machine 1 to reduce the discharge of shot blasting dust. When the H-beam is fed into the shot blasting machine 1 for processing, the dust generated by the shot blasting machine 1 is sent to the dust removal component 2 through the dust collection pipe 3 for processing, so that large dust particles can be collected by the dust removal component 2 for easy processing and the discharged clean air.

[0035] Specifically, the dust removal assembly 2 includes a chamber 21, a sealing door 22, and a base 23. The chamber 21 is equipped with a dust removal structure for centralized filtration and collection of shot blasting dust. The sealing door 22 is hinged to the front of the chamber 21. The sealing door 22 is a common revolving door component. A lock can be installed between the sealing door 22 and the chamber 21 to facilitate locking the sealing door 22 when the chamber 21 is in use and to quickly open the sealing door 22 when it is necessary to operate the components inside the chamber 21. The base 23 is fixedly connected to the bottom surface of the chamber 21 to increase the distance between the chamber 21 and the placement surface.

[0036] Furthermore, the dust removal structure includes a first pipe connected to the dust collection pipe 3 at its top and a second, third and fourth pipe connected to the first pipe in a top-to-bottom order. The first and second pipes are connected in a detachable manner to facilitate the removal and cleaning of the filtered dust.

[0037] Specifically, the first pipe includes an air inlet pipe 31 whose outer wall is fixed to the chamber 21, and the top end of the air inlet pipe 31 is fixedly connected to the dust collection pipe 3. The second pipe includes a dust filter pipe 41 whose inner wall is inserted into the air inlet pipe 31, so that shot blasting dust can be sent into the air inlet pipe 31 through the dust collection pipe 3 and then into the dust filter pipe 41.

[0038] The air inlet pipe 31 has a protruding sealing ring 32 fixed on its outer side. The top surface of the dust filter pipe 41 is in contact with the sealing ring 32. The dust filter pipe 41 is detachably installed with a filter screen 42 inside. The inner wall of the dust filter pipe 41 is in contact with the air inlet pipe 31, so that the air inlet pipe 31 can be airtight when connected with the dust filter pipe 41.

[0039] The filter cylinder 42 has a columnar structure with an open top and a mesh structure on the rest. A raised ring 43 is fixed on the inner wall of the dust filter tube 41. The bottom end of the filter cylinder 42 is in contact with the raised ring 43, and the outer side of the filter cylinder 42 is in close contact with the inner wall of the dust filter tube 41. This allows large dust particles carried inside the filter cylinder 42 to be filtered out and collected when the dusty gas is sent downward through the filter cylinder 42.

[0040] Furthermore, the third pipeline includes a receiving pipe 51 and flanges 52 fixed at both ends of the receiving pipe 51. The receiving pipe 51 is made of a flexible material. In practice, the material of the receiving pipe 51 can be rubber, which has strong elastic deformation capability.

[0041] Specifically, the fourth pipeline includes an exhaust pipe 61 whose outer wall is fixed to the chamber 21 and a fan 62 fixedly connected to the bottom end of the exhaust pipe 61. The upper and lower ends of the receiving pipe 51 are fixedly connected to the dust filter pipe 41 and the exhaust pipe 61 respectively through flanges 52. Both the dust filter pipe 41 and the exhaust pipe 61 are provided with flange structures for bolting to the flanges 52, so that the fan 62 generates an outward suction force, thereby drawing the dust gas inside the shot blasting machine 1 into the dust collection pipe 3, and finally discharging the filtered gas through the exhaust pipe 61 and the fan 62.

[0042] During implementation, the outer wall of the dust filter tube 41 is connected to the adjustment component, and the dust filter tube 41 is linearly displaced along the height direction of the chamber 21 by the guide. The adjustment component drives the dust filter tube 41 to move up and down, so that the dust filter tube 41 can be quickly separated from the air inlet tube 31, thereby making it convenient to remove the filter screen cylinder 42 from the dust filter tube 41.

[0043] Specifically, the adjustment assembly includes a cylinder 71 and a push plate 72 fixedly connected to the outer wall of the dust filter pipe 41. The piston rod of the cylinder 71 is fixedly connected to the push plate 72, and the cylinder 71 is fixedly mounted in the chamber 21 through a mounting bracket 73. The mounting bracket 73 is fixedly connected to the outer wall of the cylinder 71 and is fixed to the inner wall of the chamber 21. Thus, the piston rod is extended and retracted by the cylinder 71, so that the dust filter pipe 41 can be quickly inserted into or separated from the air inlet pipe 31.

[0044] The guide includes a vertical rod 81 fixed at both ends in the chamber 21 and a slide 82 slidably connected to the vertical rod 81 at one end. The vertical rod 81 is parallel to the height direction of the chamber 21. The other end of the slide 82 is fixedly connected to the dust filter pipe 41. The slide 82 can only move vertically up and down along the height direction of the vertical rod 81, so as to facilitate the dust filter pipe 41 to maintain a stable synchronous displacement.

[0045] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
