[0053] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention, and for ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0054] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the embodiments of the present invention are not therefore limited to the following embodiments.

[0055] Combination Figure 1-Figure 9 As shown, the present invention provides a waste filtering and collecting device for a shot blasting machine, comprising a base 1, a cylinder 2 fixed on the base 1, a cover structure 3 on the cylinder 2, a partition 4 is provided in the cylinder 2, the partition 4 is fixedly connected to the inner wall of the cylinder 2, and the cylinder 2 is divided into a first cylinder part 5 and a second cylinder part 6, and a filtering and collecting mechanism 7 and a cleaning mechanism 8 are provided in the cylinder 2.

[0056] According to one embodiment of the present invention, the filter collection mechanism 7 includes a rotating disk 71, a driving cone 72, a filter cylinder 73, a swing connection 74, a cleaning assembly 75, a driving device 76 and a protective guide device 77.

[0057] In this embodiment, the upper side of the partition 4 has an annular flange 41, and the rotating disk 71 is located in the annular flange 41 and is rotatably connected to the partition 4. The driving cone 72 is located on the upper side of the rotating disk 71 and is fixedly connected to the rotating disk 71. In this embodiment, the driving cone 72 is fixedly connected to the rotating disk 71 through a middle connecting cylinder 721. The inner surface of the driving cone 72 is a rough surface. The filter cartridge 73 of the present invention has an open end and a closed end, and is used to accommodate waste. The swing connector 74 is located on the lower side of the filter cartridge 73 and is fixedly connected to the middle of the closed end of the filter cartridge 73. The cleaning assembly 75 is arranged in the filter cartridge 73.

[0058] According to an embodiment of the present invention, the cleaning assembly 75 of the present invention comprises a mounting seat 751, a limiting column 752, a fixing ring 753 and a chain structure 754. In this embodiment, the mounting seat 751 is fixedly mounted on the inner wall of the filter cartridge 73, the limiting column 752 is mounted on the mounting seat 751, the fixing ring 753 is mounted on the limiting column 752, the chain structure 754 is hinged to the fixing ring 753, and the chain structure 754 has a collision block 755. Along the circumference and axial direction of the filter cartridge 73, a plurality of cleaning assemblies 75 are evenly spaced on the inner wall of the filter cartridge 73.

[0059] According to one embodiment of the present invention, the driving device 76 of the present invention is used to drive the rotating disk 71 to rotate. The specific structure is configured to include a mounting tube 761 installed on the lower side of the partition 4 and a variable frequency motor 762 fixedly installed in the mounting tube 761. A through hole is provided on the partition 4, and the output shaft of the variable frequency motor 762 passes through the through hole and is fixedly connected to the rotating disk 71.

[0060] In addition, the waste filtering and collecting device of the shot blasting machine of the present invention has the lower end annular surface of the driving cone 72 eccentrically arranged with respect to the upper end annular surface along the vertical direction, and the swing connecting member 74 passes through the driving cone 72 and is hingedly connected to the rotating disk 71, for example, by a universal ball connection, and the swing connecting member 74 abuts against the inner wall of the driving cone 72 and slides with the driving cone 72.

[0061] The waste filtering and collecting device of the shot blasting machine of the present invention can place the waste of the shot blasting machine in the filter drum 73 as needed, and drive the rotating disk 71 to rotate through the drive of the variable frequency motor 762, thereby realizing the rotation of the driving cone 72, and since the swing connecting member 74 fixedly connected to the filter drum 73 passes through the driving cone 72 and is hingedly connected to the rotating disk 71, and the swing connecting member 74 abuts against the inner wall of the driving cone 72 and is slidably connected to the driving cone 72, during the rotation of the rotating disk 71, the filter drum 73 moves with it, and at the same time, since the driving cone 72 moves with it, the driving cone 72 and the rotating disk 71 are connected. The swing connector 74 is slidably matched, and the lower end annular surface of the driving cone 72 is eccentrically arranged with the upper end annular surface, that is, the inner surface of the driving cone 72 is an irregular cone surface, so that when the driving cone 72 rotates, the swing connector 74 can be realized, and then the swing effect of the filter cylinder 73 can be realized, so that the collision effect between the waste in the filter cylinder 73, between the waste and the cleaning component 75, and between the waste and the inner wall of the filter cylinder 73 can be increased. In the above mutual collision process, the waste constantly changes its position, which is conducive to improving the cleaning effect and can effectively clean up impurities such as oil, rust, and paint on the waste. Setting the inner surface of the driving cone 72 as a rough surface is conducive to improving the movement stability of the swing connector 74.

[0062] Combination Figure 3-Figure 5 , Figure 10-12 As shown, the cleaning mechanism 8 of the present invention comprises an annular nozzle 81 and a high-pressure water supply pipeline 82 connected to the annular nozzle 81, wherein the annular nozzle 81 is located at the top of the cylinder 2 and fixedly installed on the lower side of the cover structure 3, one end of the high-pressure water supply pipeline 82 is connected to the annular nozzle 81, and the other end extends out of the cylinder 2 to connect to the high-pressure water supply source. In this embodiment, the side wall of the filter cartridge 73 is provided with a plurality of second through holes 731 along its circumference near the lower end, and the outer edge of the inner bottom of the filter cartridge 73 is provided with a guide groove 732 connected to the second through hole 731.

[0063] With such a configuration, when the waste in the filter cartridge 73 is cleaned, the cleaning mechanism 8 can be used to perform high-pressure flushing on the filter cartridge 73 from above, which can not only flush the waste, but also filter and flush the impurities cleaned in the filter cartridge 73 out from the second through hole 731, thereby preventing the impurities from accumulating or adhering to the filter cartridge 73 and affecting the cleaning effect of the next waste. A guide groove 732 is provided on the outer edge of the bottom of the filter cartridge 73 and is connected to the second through hole 731, which can further improve the discharge effect of the cleaned impurities.

[0064] Combination Figure 3-Figure 6As shown, the lower end surface of the filter cylinder 73 of the present invention is also fixedly connected to a protective flow guide device 77, and the swing connector 74 and the driving cone 72 are located inside the protective flow guide device 77. In this embodiment, the protective flow guide device 77 includes a first conical cylinder portion 771 and a second conical cylinder portion 772 connected in sequence, and the generatrix inclination angle of the first conical cylinder portion 771 is greater than the generatrix inclination angle of the second conical cylinder portion 772. On the one hand, it can avoid interference with the movement of the driving cone 72 during movement, and on the other hand, it ensures that the sewage containing impurities discharged from the second through hole 731 flows downward through the protective flow guide device 77. In this embodiment, the maximum outer diameter of the second conical cylinder portion 772 of the present invention is greater than or equal to the outer diameter of the rotating disk 71. Such a configuration can ensure that the sewage containing impurities flows to the annular flange 41 of the partition 4 under the guidance of the protective flow guide device 77, and will not affect the structural parts such as the rotating disk 71.

[0065] In addition, due to the provision of the protective guide device 77, the stability of the relative sliding between the filter cylinder 73 and the driving cone cylinder 72 can also be improved.

[0066] Combination Figure 3-Figure 5 As shown, according to one embodiment of the present invention, the upper surface of the annular flange 41 of the partition 4 of the present invention is a conical surface. Specifically, the height of the annular flange 41 gradually decreases along the direction away from the rotating disk 71. The annular flange 41 is provided with a plurality of first through holes 42 along its circumference, and the first through holes 42 connect the first cylinder part 5 and the second cylinder part 6. In this embodiment, the lower end of the second cylinder part 6 is fixed on the base 1 in a closed manner, and the second cylinder part 6 includes a conical guide cylinder part 61 and a bottom cylinder part 62 connected in sequence, and a collecting pipe 63 is connected to the bottom cylinder part 62.

[0067] With such arrangement, the sewage containing impurities can be filtered along the protective guide device 77 to the annular flange 41, and then flow into the second cylinder part 6 through the first through hole 42. The second cylinder part 6 acts as a water tank, wherein the conical guide cylinder part 61 acts as a guide. The second cylinder part 6 transports the sewage containing impurities backward through the collection pipe 63 for subsequent treatment.

[0068] The waste filtering and collecting device of the shot blasting machine of the present invention has the following working principle:

[0069] The frequency conversion motor 762 drives the rotating disk 71 to rotate. Due to the drive cone 72 and the swing connector 74, the filter cartridge 73 can be rotated and swung, thereby increasing the position change and impact of the waste in the filter cartridge 73 and the cleaning assembly 75, achieving a better cleaning effect, and cleaning the impurities such as oil, rust, and paint on the waste. The frequency conversion motor 762 can control the forward and reverse rotation of the rotating disk 71, so that the forward and reverse cycles can be set as needed to further improve the cleaning effect.

[0070] After the filter collection mechanism 7 is cleaned, the cleaning mechanism 8 works and sprays water to the filter cartridge 73 through the annular nozzle 81. At this time, the variable frequency motor 762 can be in a stopped state or in a low-speed working state. With such a setting, during the water spraying process, due to the rotation and swing of the filter cartridge 73, the waste inside also has position changes, which can achieve a better flushing effect. It is particularly important to emphasize that due to the above-mentioned setting of the cleaning component 75, the impact block 755 of the cleaning component 75 will also impact the inner wall of the filter cartridge 73, which is conducive to reducing the problem of impurities adhering to the inner wall of the filter cartridge 73. Finally, the flushing water carries the cleaned impurities through the second through hole 731 and the first through hole 42 and is filtered into the second barrel part 6 for subsequent treatment.

[0071] According to the present invention, the cleaning mechanism 8 is set up, and the high-pressure water supply pipeline 82 can be connected not only to a high-pressure water source, but also to a high-pressure gas source at the same time, so that after flushing, the high-pressure gas source can be turned on for high-pressure gas supply, which can enhance the cleaning effect on the one hand, and dry the waste on the other hand. Of course, the high-pressure water source can also be replaced with a high-pressure source, and filtering can be performed by high-pressure ventilation.

[0072] In addition, the waste filtering and collecting device of the shot blasting machine of the present invention, through the above-mentioned structural setting, makes the overall structure of the device more compact and reasonable, which is specifically reflected in, for example, dividing the cylinder 2 into the first cylinder part 5 and the second cylinder part 6, and the second cylinder part 6 can be used as a water tank. For another example, the cooperation of the driving cone 72 and the swing connecting member 74 can not only improve the impact cleaning effect, but also cooperate well with the top cleaning mechanism 8 to achieve the purpose of improving the cleaning effect while saving water.

[0073] The above is only one embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
