Description
Technical Field
[0001] The utility model belongs to the technical field of shot blasting machines, and in particular relates to a shot blasting machine which is convenient for separating shot blasting residues. Background Art
[0002] Shot blasting machine is a processing technology that uses a shot blaster to throw steel shots at high speed to impact the surface of the material. The burrs, rust or surface dirt on the surface of the material are removed by throwing steel shots at high speed to impact the surface of the material. During the cleaning process, the slag on the surface of the material will adhere to the steel shots. Among them, a large amount of steel shots are required for cleaning the material. The number of steel shots loaded by the machine itself is limited. Therefore, the recycling of steel shots is more important.
[0003] When the shot-slag separation device of the existing shot blasting machine is performing shot-slag separation, because it uses steel shots to impact and clean the materials, this will produce block or powder material slag. The traditional separation device generally uses a filter screen filtering method to screen the slag and steel shots. The finer slag can be well screened out from the bottom of the filter screen, while the larger pieces of slag will continue to be mixed with the steel shots, resulting in incomplete separation of the shot-slag, thereby reducing the cleaning effect, affecting the surface treatment quality of the workpiece, and reducing the use efficiency of the equipment and increasing the maintenance cost of the equipment.

DETAILED DESCRIPTION
[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0021] like Figure 1-5 As shown, a shot blasting machine for separating shot and residue includes a shell 1, a shot blasting machine body 2 and a conveyor belt 3. A feed port is provided on the upper right side of the shell 1, and a feed hopper 4 is installed on the upper side of the feed port. The shot blasting machine body 2 is arranged at the rear side of the shell 1, and the conveyor belt 3 is installed on the right side of the shot blasting machine body 2. The feed end of the conveyor belt 3 matches the inner side of the shot blasting machine body 2, and the discharge end of the conveyor belt 3 is located on the upper side of the feed hopper 4. A separation device is installed on the inner side of the shell 1.
[0022] The separation device includes a sieve plate 6, a plurality of small sieve holes 7 are evenly opened on the right side of the sieve plate 6, a plurality of large sieve holes 8 are evenly opened on the left side of the sieve plate 6, two baffles 9 are vertically installed at the bottom of the shell 1, one baffle 9 matches the middle part of the sieve plate 6, and the other baffle 9 matches the left side of the sieve plate 6, a shot blasting funnel 10 is installed at the bottom of the shell 1 and between the two baffles 9, the shot blasting funnel 10 is connected to the inside of the shot blasting machine body 2, two waste slag funnels 11 are installed at the bottom of the shell 1 and on the left and right outsides of the two baffles 9, and a motion component is connected to the lower side of the sieve plate 6 through transmission.
[0023] When in use, the shot blasting machine body 2 processes the workpiece, and the processed shot slag enters the conveyor belt 3 from the feeding end of the conveyor belt 3 matched therewith, and the shot slag mixture is transmitted to the output end of the conveyor belt 3 through the conveyor belt 3 and finally falls into the inner side of the feed hopper 4, and the sieve plate 6 is located below the feeding port. When the shot slag needs to be separated, the shot slag enters the inner side of the feed hopper 4, the diameter of the small sieve hole 7 is slightly smaller than the diameter of the steel shot, and the diameter of the large sieve hole 8 is slightly larger than the diameter of the steel shot. The sieve plate 6 is slightly inclined downward from right to left, so the shot slag enters from the right side of the sieve plate 6 and can slide to the left side, one of the baffles 9 is below the middle part of the sieve plate 6, and the other baffle 9 is below the left end of the sieve plate 6. When the shot slag passes through the small sieve hole 7, the powdered slag and smaller slag pass through the small sieve hole 7 and are discharged from the waste slag funnel 11 located on the right.
[0024] When the shot slag passes through the large sieve hole 8, the steel passes through the large sieve hole 8 and is discharged from the shot blasting funnel 10, and finally enters the inner side of the shot blasting machine body 2. The larger block slag is discharged from the left side of the sieve plate 6 into the waste slag funnel 11 on the left side, and finally discharged from the waste slag funnel 11 on the left side.
[0025] The cooperation between the small sieve holes 7 and the large sieve holes 8 enables the separation device of the shot blasting machine to separate smaller powdery slag from steel shots while also separating larger blocky slag during shot-slag separation, making the shot-slag separation more thorough, thereby improving the cleaning effect of the shot blasting machine and the surface treatment quality of the workpiece, improving the working efficiency of the shot blasting machine and reducing the use cost of the shot blasting machine. The motion component can move the sieve plate 6 to increase its screening efficiency.
[0026] There are four groups of motion components, and two groups of two are located on the front and rear sides of the sieve plate 6 respectively. The motion components include a support frame 12, which is fixedly connected to the shell 1. A rotating rod 13 is rotatably installed on the upper side of the support frame 12, and a short crank 14 is fixedly installed on the upper side of the rotating rod 13. A rotating shaft 15 eccentric to the rotating rod 13 is fixedly installed on the upper side of the short crank 14. The rotating shaft 15 is rotatably connected to the sieve plate 6, and the rotation directions of the short cranks 14 of the four groups of motion components are consistent. The lower sides of the two rotating rods 13 located on the front side are both transmission-connected with pulleys 16, and a transmission belt 17 is transmission-connected between the two pulleys 16. A motor 18 is installed on the lower side of the pulley 16, and the output end of the motor 18 is transmission-connected to one of the pulleys 16.
[0027] The crank cooperates with the eccentric rotating shaft 15 so that the sieve plate 6 as a whole can make a circular motion around the four rotating rods 13 on the inclined plane of the sieve plate 6. When the sieve plate 6 is working, the motor 18 is started, and the output end of the motor 18 drives one of the pulleys 16 to rotate, and the power is transmitted to the other pulley 16 through the transmission belt 17, so that the moving component located on the front side can run synchronously, so that the sieve plate 6 can always be kept in the left and right direction during operation to avoid jamming.
[0028] The motor 18 and the motion assembly can make the screen plate 6 as a whole continuously perform circular motion, thereby increasing the screening efficiency of the screen plate 6. The cooperation between the pulley 16 and the transmission belt 17 can ensure the smooth operation of the screen plate 6 and avoid jamming. At the same time, the pulley 16 and the transmission belt 17 make the structure of the motion assembly simple, improve its reliability, and reduce maintenance costs.
[0029] The small sieve holes 7 are elongated through holes.
[0030] Since the small sieve holes 7 are smaller than the diameter of the steel shots, the steel shots cannot pass through the small sieve holes 7 . Therefore, the elongated through holes can improve the screening efficiency of the sieve plate 6 for small-volume and powdery slag, so that the small-volume slag can be screened thoroughly.
[0031] The large sieve holes 8 are circular through holes.
[0032] Since the large sieve holes 8 are slightly larger than the diameter of the steel shots, bulk slag larger than the steel shots cannot pass through the large sieve holes 8. Therefore, the circular through holes can improve the screening efficiency of the sieve plate 6 for bulk slag with larger volume, thereby improving the purity of the steel shots.
[0033] A control valve 5 is installed at the lower side of the feed hopper 4.
[0034] The main function of the control valve 5 is to control the flow rate of the pellet-slag mixture through the feed hopper 4, and to start and stop the flow of the pellet-slag mixture. Since the control valve 5 is an existing public technology, it will not be described in detail. The control valve 5 can control the flow rate of the pellet-slag and thus control the uniformity and efficiency of the screening process of the separation device, thereby improving the screening quality.
[0035] A notch is provided on the upper side of the housing 1 , a slide rail 19 is installed on the upper side of the notch, and an inspection cover 20 is slidably installed on the upper side of the slide rail 19 .
[0036] The inspection cover 20 can be slid open to allow technicians to conveniently clean or maintain the interior of the separation device to ensure the normal operation of the separation device.
[0037] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
