Description

Technical Field

[0001] The utility model relates to the field of sandblasting process auxiliary equipment and devices, in particular to a sandblasting particle layered recovery box. Background Art

[0002] Sandblasting is a method of using compressed air to spray abrasives onto metal surfaces for treatment. Sandblasting sprays sand and other media onto the surface of an object through a high-speed sand stream. This impact can effectively remove impurities on the surface of the object and improve the fatigue resistance, adhesion and durability of metal workpieces. Sandblasting can also remove rust and old paint layers on the surface of the workpiece, prepare a good base layer for coating, bonding or other finishing, and enhance the bonding strength between the coating or adhesive and the surface of the workpiece. In the wet sandblasting process, abrasives are mixed with water into a slurry-like substance and then sprayed. This is usually used to prevent oxidation or rust of metal materials during the treatment process.

[0003] During the sandblasting process, a large number of sandblasting particles used to process the surface of the workpiece will pop out or drift outward after colliding with the workpiece, so the sandblasting process is usually carried out in a relatively closed hollow box. For these sandblasting particles after use, considering factors such as environmental protection, economic benefits, and improving efficiency and processing quality, these sandblasting particles are usually recycled and put into use again. Since the sandblasting particles used in the sandblasting process usually adopt two or more types of mixed states, and the debris generated on the surface of the workpiece during the sandblasting process will also be mixed into the particles, it is necessary to screen these sandblasting particles after use before they can be put into use again. Some existing devices and equipment can already achieve good screening of sandblasting particles. For example, a sandblasting abrasive screening and recovery device for sandblasting equipment disclosed in the Chinese utility model patent document with application number CN202311659710.0 includes a box, and a plurality of screens with different apertures are arranged in sequence from top to bottom inside the box. The sandblasting abrasive screening and recovery device of the sandblasting equipment removes the limit plates on the rear surface of the box body and the rear surface, and then pulls the screen outwards through the first pulling plate, and the screen can be taken out from the interior of the box body under the support of the clamping seat; when the screen needs to be installed, the screen is inserted into the interior of the box body through the insertion groove on the front surface of the box body, and the first pulling plate on the rear surface of the screen is supported by the clamping seat to pass through the interior of the through groove and extend to the outside of the first pulling plate on the rear surface of the box body, and then the limit plate is installed on the first pulling plate to complete the installation and fixation of the screen, which solves the problem of inconvenient disassembly and assembly of the screen in the prior art.

[0004] However, for the sandblasting abrasive screening and recovery device provided in the technical solution of the above-mentioned patent document, after a certain period of screening and recovery, a large amount of sandblasting particles of a certain size will accumulate on the surface of the upper screen, thereby causing the small-size sandblasting particles that should have passed through the upper screen to be unable to fall smoothly downward after screening, thereby causing the device to have a low effect in separating and recovering different types of sandblasting particles.

[0005] In view of the above problems, the utility model provides a sandblasting particle layered recovery box which can fully separate different types of sandblasting particles and timely recover each part of the sandblasting particles as the sandblasting particles continue to enter, thereby always ensuring that the equipment has an efficient screening and recovery effect.

[0027] The following specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0028] This solution is achieved through the following technical means:

[0029] Embodiment: The sandblasting particle sealing layer recovery box provided in the present embodiment can fully separate different types of sandblasting particles and recover each part of the sandblasting particles in time, thereby always ensuring that the equipment has an efficient screening and recovery effect.

[0030] First of all, before explaining the present embodiment, it is necessary to briefly introduce the screening and recovery of sandblasting particles. In the process of sandblasting the surface of the workpiece, due to the collision and friction between the particles and the surface of the workpiece, a small amount of metal debris will inevitably be generated and mixed into this part of the sandblasting particles. The existence of such debris will make it difficult to control the state of the injection impact of the sandblasting particles during repeated recycling, which is not only easy to cause scratches on the surface of the workpiece and reduce the quality of surface treatment, but also cause the sandblasting equipment to be blocked and damage the wind direction. In addition, due to different requirements for process treatment at different positions on the surface of the workpiece, a variety of different types of sandblasting particles are often used in the process of surface sandblasting.

[0031] Therefore, based on the premise of green environmental protection and recycling of resources, the sandblasting particles should be subjected to corresponding secondary treatment after the work is completed before they can be put into repeated recycling to avoid the occurrence of the above problems.

[0032] Specifically, the device mainly includes a hollow main box 1, and a hollow chamber 101 is formed inside the main box 1, which is used to install the sandblasting particle screening system 2 set inside. Specifically, the system includes a particle recovery bin arranged at the bottom of the hollow chamber 101. The particle recovery bin is formed by welding a plurality of metal plates together, and the overall shape is a hollow box body that is concave from top to bottom, and is used to receive and carry the sandblasting particles that have been screened and removed from impurities and fall from top to bottom. Of course, a particle injection port 103 is also required to be provided at the top of the main box 1, and a material extraction opening 104 is provided at the lower part of the side wall of the main box 1 for the particle recovery bin 201 to escape outward.

[0033] The sandblasting particle screening system 2 also includes a plurality of screening filter plates 202 arranged from top to bottom and parallel to each other. Figure 1 In the structure shown, the screening filter plate 202 is set in an inclined state. It should be noted that the higher end of the screening filter plate 202 needs to be close to the side of the aforementioned particle injection port 103, so that when the impurity-containing sandblasting particles to be processed enter the box, they will first contact with the upper side of the uppermost screening filter plate 202 and be supported there. At this time, a driving mechanism 4 can be used to drive the screening filter plate 202 to vibrate in a certain direction, so that the sandblasting particles to be processed can pass through the screening filter plate downward while moving to the lower side under the action of the inclined surface.

[0034] Specifically, the structure of the screening filter plate 202 here mainly includes a frame part 203 arranged on the outside to play a connecting and fixing role, and a screen part 204 located in the central area. On the front and rear sides of the main box 1 mentioned above, installation slots 102 are formed for inserting the front and rear ends of the screening filter plate 202. Then, when the two ends of the screening filter plate 202 are respectively inserted into the installation slots 102 on both sides, the plate can perform reciprocating translational motion along the extension direction of the installation slot 102. It should be noted here that the apertures of the filter parts in the multi-layer screening filter plate 202 from top to bottom are different, and the apertures of these filter parts gradually decrease from top to bottom, so as to realize the separation of the various sandblasting particles to be processed layer by layer according to the particle size or to screen and remove impurities of different sizes from the sandblasting particles in sequence, until the sandblasting particles that have been finally processed are obtained, which can be conveniently put into new processing and use work.

[0035] The driving mechanism 4 for driving the aforementioned screening filter plate 202 to reciprocate and vibrate mainly comprises a motor 401 arranged inside the installation slot and a supporting cam 402 installed on the output shaft of the motor 401 and rotating around a fixed central axis, wherein the screening filter plate 202 abuts against the front end face of the supporting cam 402, and a supporting spring component 403 is arranged between the rear end face of the screening filter plate 202 and the main box body 1. When the motor 401 continuously rotates, in the initial state, the supporting cam 402 can continuously support the front end face of the screening filter plate 202, and the supporting spring component 403 located at the rear side will be compressed; as the motor 401 device continues to rotate, the supporting cam 402 continues to deflect to a position where it cannot effectively support the screening filter plate 202, and at this time, under the action of the supporting spring component 403, the screening filter plate 202 will be pushed forward. This repetition provides a vibration effect to the screening filter plate 202, thereby effectively preventing the sandblasting particles from being stacked, agglomerated, and stuck on the screen portion 204, and also avoiding the problem of low screening efficiency.

[0036] Further preferably, refer to the attached specification Figure 1 In the structure shown here, in order to recycle the impurities or sandblasting particles with larger particle size discharged by each level of the screening filter plate 202, an impurity screening recovery box 3 can be installed on the outer side of the lower end of the screening filter plate 202 by mounting, and a transition guide plate 301 is also provided between the impurity screening recovery box 3 and the screening filter plate 202. Then at this time, with the vibration of the screening filter plate 202, the sandblasting particles to be processed carried on the screen part 204 can be screened and dropped layer by layer, and the sandblasting particles retained on the screen part 204 can be gradually moved to a lower place under the guidance of the inclined surface until they move into the impurity screening recovery box 3 through the transition guide plate 301, thereby realizing the centralized screening treatment of impurities of this type of particle size. Of course, the existence of the impurity screening recovery box 3 can not only complete the screening treatment of impurities, but also can carry out targeted layered screening of sandblasting particles of different particle sizes, and conveniently recycle them.

[0037] For the aforementioned material taking opening 104, during the screening process, the chamber inside the main box body 1 needs to be relatively closed, and after the screening process is completed, the aforementioned particle recovery bin 201 needs to be pulled out from there using the material taking opening 104. Therefore, at the material taking opening 104, an opening and closing bin door 5 that can conveniently control the change of the open or closed state of the main box body 1 should also be installed. Specifically, in the present embodiment, the structure of the opening and closing bin door 5 that can be lifted and moved in the vertical direction can be realized by a drive rack fixedly installed on the door panel, and a gear structure fixedly installed on the output end of the stepping motor 401 and meshing with the drive rack. Of course, the structure can also be replaced by a lifting transmission mechanism such as a chain or a crawler, which will not be expanded here.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
