Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically to a shot blasting machine steel shot recycling and screening device. Background Technology

[0002] Shot blasting machine is a casting equipment that uses high-speed shot to clean or strengthen the surface of castings. Shot blasting machine can simultaneously remove sand, core and clean castings. In some areas, it is also colloquially called sandblasting machine or sandblasting machine. Compared with other surface treatment technologies, it is faster and more efficient. After use, shot blasting machine needs to be screened and recycled. Since different steps have systematic requirements for shot of different diameters, a screening device is needed to classify and recycle the shot.

[0003] When the shot blasting machine finishes its work, the workers need to screen the shot produced by the machine and clean the waste material off the shot. This not only increases the labor intensity of the workers, but also reduces the screening efficiency.

[0004] For example, patent application number 202420321231.1 discloses a shot blasting screening and recycling device for a shot blasting machine. This utility model discloses a shot blasting screening and recycling device for a shot blasting machine, including a shot blasting machine and a screening box. A feed pipe is provided at the bottom of one side of the shot blasting machine, and the other end of the feed pipe is fixedly installed to the top of the screening box. A first screen plate is provided inside the screening box, and a second screen plate is provided inside the screening box below the first screen plate. By setting the first screen plate and the second screen plate, the mixed waste material and shot blasting conveyed by the feed pipe are screened, which reduces the labor intensity of workers and improves the screening efficiency. However, when screening steel shot, the shot blasting screening and recycling device of this shot blasting machine will accumulate impurities, debris or dust in the steel shot in the screen holes after long-term use, resulting in a reduction in the effective filtration area and a slowdown in the steel shot grading speed.

[0005] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a steel shot recycling and screening device for shot blasting machines. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-5As shown, a steel shot recycling and screening device for shot blasting machines includes a main body 1 with a feed pipe 101 on its upper surface, a support frame 102 on its lower surface, a vibration device 103 on its upper surface, elastic resetters 104 on both sides of the support frame 102, and a discharge plate 105 on its front surface. This technical solution uses the vibration device 103 to generate vibration by hammering the upper surface of the support frame 102, thereby screening the material.

[0027] Furthermore, a screening plate 2 is slidably installed on the inner surface of the support frame 102, and a connecting plate 201 is provided on the rear surface of the screening plate 2. A handle 202 is provided in the middle of the surface of the connecting plate 201, and a positioning block 203 is provided above the handle 202. This technical solution, through the setting of the double-layer screening plate 2, can classify and screen steel sand by setting the size of the holes, thereby improving the screening speed and reducing the frequency of steel sand getting stuck in the screening plate 2. Through the setting of the connecting plate 201, the double-layer screening plate 2 can be pulled out for quick replacement and maintenance, thereby improving the maintenance speed of the screening plate 2 and improving the working efficiency of the screening device.

[0028] Furthermore, a connecting block 204 is provided on the rear surface of the support frame 102, and a sliding insert rod 205 is slidably installed through the surface of the connecting block 204. The sliding insert rod 205 and the positioning block 203 are slidably connected. With this technical solution, the sliding insert rod 205 can be inserted into the interior of the positioning block 203 in a sliding manner to fix the screening plate 2.

[0029] Furthermore, a lifting plate 206 is provided on the upper surface of the sliding rod 205, and a return spring 207 is provided on the outer surface of the sliding rod 205. With this technical solution, the return spring 207 can drive the sliding rod 205 to slide by means of its reset characteristic, so as to prevent it from loosening during operation.

[0030] like Figure 6 As shown, a collection box 307 is slidably installed on the lower outer surface of the main body 1 of the screening device, and the collection box 307 is located below the support frame 102. With this technical solution, the collection box 307 can collect unqualified materials and dust, and can also be quickly removed and cleaned by sliding.

[0031] Furthermore, a connecting plate 3 is provided on the end surface of the collection box 307, and a handle 301 is provided on the surface of the connecting plate 3. A magnetic block 302 is provided on the upper surface of the connecting plate 3, and the magnetic block 302 is magnetically connected to the main body 1 of the screening device. With this technical solution, the collection box 307 can be magnetically attracted and fixed by the setting of the magnetic block 302, thereby improving the stability of the collection box 307 during operation.

[0032] Furthermore, the inner surface of the collection box 307 is provided with an inclined plate 303, and the lower surface of the inclined plate 303 is provided with an air inlet plate 304. The upper surface of the air inlet plate 304 is provided with a dust filter 305, and the outer surface of the air inlet plate 304 is provided with an air suction device 306. This technical solution, through the setting of the dust filter 305, can filter the dust attached to the air inlet plate 304, preventing dust from clogging the air suction device 306; through the setting of the air suction device 306, suction can be generated below the support frame 102 to guide and collect the dust during material feeding, so that it can fall accurately into the inside of the collection box 307 for collection, preventing dust from flying around and sticking to the surface of the screening plate 2, reducing the frequency of removing and maintaining the screening plate 2, and improving the screening efficiency of the equipment.

[0033] Working principle: When using the steel shot recycling and screening device of this shot blasting machine, firstly, after the shot blasting operation is completed, the mixture of steel shot, dust, and impurities enters the screening plate 2 through the feed pipe 101. At this time, the vibration device 103 is activated, driving the screening plate 2 through high-frequency vibration to achieve precise grading and filtration of the steel shot. Steel shot that meets the standards is smoothly discharged along the discharge plate 105, while unqualified materials, along with dust and impurities, fall into the collection box 307.

[0034] To prevent dust from scattering during the material feeding process and affecting collection efficiency and the working environment, the suction device 306 can be turned on. The suction force will adsorb the suspended dust onto the inclined plate 303 and guide it into the collection box 307; a small amount of dust that escapes will be intercepted and filtered by the dust filter 305 before being discharged, effectively avoiding secondary dust generation.

[0035] After waste collection is complete, gently pull handle 301 to disengage the magnetic block 302 from the main body 1 of the screening device, allowing easy removal of the collection box 307 for quick cleaning of the waste and dust accumulated on the surface of the filter screen 305. When the screening plate 2 becomes clogged, pull the lifting plate 206 outward to disengage the sliding rod 205 from the locking position block 203, then pull handle 202 to smoothly remove the screening plate 2 along the inner surface of the support frame 102, completing a convenient and efficient cleaning and replacement. This is the working principle of the shot blasting machine's steel shot recycling and screening device.
