Technical Field
[0001] The utility model relates to the technical field of sandblasting treatment, and more specifically, it relates to a sandblasting treatment device for the surface of metal castings. Background Art
[0002] The sandblasting treatment device for metal castings is used to remove rust, scale and old coatings on the metal surface to prepare for subsequent processes such as painting and electroplating. This kind of device requires a large amount of abrasive grains and high-pressure gas. There are a large number of metal impurities in the abrasive grains after sandblasting treatment. Such abrasive grains with impurities cannot be immediately put into the next sandblasting work and need to be decontaminated. These metal impurities are usually waste chips generated during the surface processing of metal castings, generally light burrs. By solving the problem of repeated use of abrasive grains, the work efficiency can be effectively improved.
[0003] Currently, during the process of abrasive grain treatment, a combination of horizontal recovery and vertical recovery is mainly adopted to remove impurities from the abrasive grains to be treated. Horizontal recovery mainly relies on the sand return hopper plate and the screw conveyor to function. The sand return hopper plate can effectively collect the abrasive grains to be treated, and then the screw conveyor smoothly transports these abrasive grains to the vertical recovery port. The vertical recovery part mainly consists of a hoist and an abrasive grain separator. The hoist is responsible for lifting the abrasive grains from horizontal recovery to a certain height so as to enter the abrasive grain separator. The abrasive grain separator then performs fine screening and impurity removal operations on the abrasive grains through a specific working principle. After this series of treatments, the impurity-removed abrasive grains will fall back into the storage bin. These treated abrasive grains will flow back into the sandblasting tank and be put into production use again. However, it occupies a large area and requires more production space in actual application. At the same time, the treatment process is complicated, which not only increases the equipment maintenance cost and operation difficulty, but also may affect the production efficiency to a certain extent.
[0004] Therefore, a sandblasting treatment device for the surface of metal castings is proposed, which has the functions of reducing the floor area, simplifying the treatment process, and improving the work efficiency. Summary of the Utility Model
[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a sandblasting treatment device for the surface of metal castings that reduces the floor area, simplifies the treatment process, and improves the work efficiency.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] A sandblasting treatment device for the surface of a metal casting, comprising a sandblasting machine frame. A sandblasting machine assembly is arranged at the top of the sandblasting machine frame. Sand collection boxes are respectively arranged on both sides of the sandblasting machine frame. A sand falling port is arranged at the bottom end of the sandblasting machine assembly. A sand screening assembly is arranged at the bottom end of the sand falling port, and a driving assembly is connected inside the sand screening assembly; The sandblasting machine assembly includes a sandblasting machine housing. A sand inlet is arranged on one side of the sandblasting machine housing. A sandblasting gun is arranged inside the sandblasting machine housing; The sand screening assembly includes a sand screening housing. A discharge port is arranged at the bottom end of the sand screening housing.
[0008] The present utility model is further arranged as: A sand collection hopper is arranged at the bottom end of the sandblasting machine housing, and a screen mesh is arranged at one end of the sandblasting machine housing away from the sand collection hopper.
[0009] By adopting the above technical solution, the sand inlet arranged on the side wall of the sandblasting machine housing inputs new sand pellets or processed sand pellets through high-pressure gas pressurization. The operator controls the sandblasting gun to process the surface of the metal casting. The used sand pellets are initially screened out through the screen mesh, and are guided through the sand collection hopper into the sand falling port and then enter the subsequent sand screening assembly and driving assembly for further screening out impurities.
[0010] The present utility model is further arranged as: The discharge port is arranged in a hollow cylindrical structure, and an air spraying pipe is arranged on one side of the discharge port. The air spraying pipe is arranged in a hollow cylindrical structure.
[0011] The present utility model is further arranged as: The diameter of the air spraying pipe is smaller than that of the discharge port. An impurity outlet is arranged at the top end of the sand screening housing, and the diameter of the impurity outlet is the same as that of the air spraying pipe.
[0012] By adopting the above technical solution, the air spraying pipe arranged at the bottom end of the sand screening housing sprays high-pressure gas with controlled flow rate into the inside of the sand screening housing. The sand pellets inside the sand screening housing are heavier in mass and will not be blown upward by the high-pressure gas, while the metal debris with lighter mass, generally in the shape of thin sheets or other irregular shapes, is easily blown upward by the gas. Through the impurity outlet, the debris is sucked out of the inside of the sand screening housing. After the sand pellets are processed, they are discharged from the discharge port, realizing the reuse of the sand pellets and improving the work efficiency and the utilization efficiency of the sand pellets.
[0013] The present utility model is further arranged as: The driving assembly includes a blocking pusher. A blocking push rod is slidably connected to the bottom of the blocking pusher. A blocking plate is fixedly connected to the side of the blocking push rod away from the blocking pusher. The blocking plate is adapted to the shape of the sand screening housing, and the blocking plate is slidably connected to the sand screening housing.
[0014] The utility model is further arranged as follows: at the top end of the inner wall of the sand screening shell, two sand falling port ejectors are fixedly connected, the two sand falling port ejectors are arranged close to the sand falling port, a sand falling port push rod is slidably connected to one side of the sand falling port ejector close to the sand falling port, and a sand falling port baffle is arranged on the side of the sand falling port push rod away from the sand falling port ejector.
[0015] By adopting the above technical solution, the driving blocking ejector drives the blocking push rod to slide upward, lifting the blocking plate, so that the processed sand pellets inside the sand screening shell are discharged through the discharge port and re-enter the sand inlet to process the metal casting. When the blocking push rod slides downward, the blocking plate descends, preventing the sand pellets inside the sand screening shell from flowing out, which is convenient for processing. The two sand falling port ejectors drive the sand falling port push rod to slide, driving the sand falling port baffle to separate, so that the sand pellets to be processed inside the sand falling port enter the sand screening shell. After a certain amount of sand pellets to be processed enter the sand screening shell, the sand falling port ejector drives the sand falling port push rod to slide, closing the sand falling port baffle, and the device arranged inside the sand screening shell is used to remove impurities from the sand pellets to be processed.
[0016] In summary, the present application includes at least one of the following beneficial technical effects:
[0017] 1. The sand inlet arranged on the side wall of the sandblasting machine housing inputs new sand pellets or processed sand pellets by pressurizing with high-pressure gas. The operator controls the sandblasting gun to process the surface of the metal casting, initially screens out the used sand pellets through the screen mesh, and guides them through the sand collecting hopper into the sand falling port and into the subsequent sand screening assembly and driving assembly for further impurity screening.
[0018] 2. The air injection pipe arranged at the bottom end of the sand screening shell injects high-pressure gas with controlled flow rate into the inside of the sand screening shell. The sand pellets inside the sand screening shell are heavier and will not be blown upward by the high-pressure gas, while the lighter metal debris, generally in the shape of thin sheets or other irregular shapes, is easily blown upward by the gas. The debris is sucked out through the impurity outlet, blowing it out of the inside of the sand screening shell. After the sand pellets are processed, they are discharged from the discharge port, realizing the reuse of the sand pellets and improving the work efficiency and the usage efficiency of the sand pellets.
[0019] 3. The driving blocking ejector drives the blocking push rod to slide upward, lifting the blocking plate, so that the processed sand pellets inside the sand screening shell are discharged through the discharge port and re-enter the sand inlet to process the metal casting. When the blocking push rod slides downward, the blocking plate descends, preventing the sand pellets inside the sand screening shell from flowing out, which is convenient for processing. The two sand falling port ejectors drive the sand falling port push rod to slide, driving the sand falling port baffle to separate, so that the sand pellets to be processed inside the sand falling port enter the sand screening shell. After a certain amount of sand pellets to be processed enter the sand screening shell, the sand falling port ejector drives the sand falling port push rod to slide, closing the sand falling port baffle, and the device arranged inside the sand screening shell is used to remove impurities from the sand pellets to be processed.

[0031] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.
[0032] It should be pointed out that unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.
[0033] Embodiment 1. Please refer to Figures 1-5 , the present utility model provides the following technical solutions:
[0034] Specifically, it refers to a surface sandblasting treatment device for metal castings. Please refer to Figures 1-2, including a sandblasting machine frame 1. The support device of the sandblasting machine frame 1 is at a height similar to that of the operator, improving the operation comfort. A sandblasting machine component 2 is arranged at the top of the sandblasting machine frame 1. The surface of the metal casting is sandblasted through the sandblasting machine component 2 to improve the mechanical properties of the metal casting. Sand collecting boxes 3 are respectively arranged on both sides of the sandblasting machine frame 1. The accumulated sand pellets are collected through the sand collecting boxes 3 to improve the work efficiency. A sand dropping port 4 is arranged at the bottom end of the sandblasting machine component 2. The used sand pellets inside the sandblasting machine component 2 are guided to flow into a sand screening component 5 through the sand dropping port 4. A sand screening component 5 is arranged at the bottom end of the sand dropping port 4. The used sand pellets are operated to remove impurities through the sand screening component 5 to realize the reuse of the sand pellets and improve the work efficiency. A driving component 6 is connected inside the sand screening component 5. The flow rate of the sand pellets is controlled through the driving component 6.
[0035] Refer to Figure 3 , the sandblasting machine component 2 includes a sandblasting machine housing 21. A sand inlet 22 is arranged on one side of the sandblasting machine housing 21. A sandblasting gun 23 is arranged inside the sandblasting machine housing 21. A sand collecting hopper 25 is arranged at the bottom end of the sandblasting machine housing 21. A screen 24 is arranged at one end of the sandblasting machine housing 21 away from the sand collecting hopper 25. Through the sand inlet 22 arranged on the side wall of the sandblasting machine housing 21, new sand pellets or processed sand pellets are pressurized and input through high-pressure gas. The operator controls the sandblasting gun 23 to process the surface of the metal casting. The used sand pellets are preliminarily screened out through the screen 24 and are guided to flow into the sand dropping port 4 through the sand collecting hopper 25 and enter the subsequent sand screening component 5 and driving component 6 for further impurity screening.
[0036] Refer to Figure 2 , the sand screening component 5 includes a sand screening housing 51. A discharge port 52 is arranged at the bottom end of the sand screening housing 51. The discharge port 52 is set as a hollow cylindrical structure. An air injection pipe 53 is arranged on one side of the discharge port 52. The air injection pipe 53 is set as a hollow cylindrical structure. The diameter of the air injection pipe 53 is smaller than that of the discharge port 52. An impurity outlet 54 is arranged at the top end of the sand screening housing 51. The diameter of the impurity outlet 54 is the same as that of the air injection pipe 53.
[0037] Specifically, the high-pressure gas with controlled flow rate is sprayed into the inside of the sand screening housing 51 through the air injection pipe 53 arranged at the bottom end of the sand screening housing 51. The sand pellets inside the sand screening housing 51 are heavier in mass and will not be blown upward by the high-pressure gas. While the metal debris with lighter mass, generally in the shape of thin flakes or other irregular shapes, is easily blown upward by the gas. The debris is blown out of the inside of the sand screening housing 51 by pumping air through the impurity outlet 54. The processed sand pellets are discharged from the discharge port 52, realizing the reuse of the sand pellets and improving the work efficiency and the usage efficiency of the sand pellets.
[0038] Refer to Figures 4-5, the driving component 6 includes a blocking pusher 61. A blocking push rod 62 is slidably connected to the bottom of the blocking pusher 61. A blocking plate 63 is fixedly connected to the side of the blocking push rod 62 away from the blocking pusher 61. The blocking plate 63 is adapted to the shape of the sand screening housing 51, and the blocking plate 63 is slidably connected to the sand screening housing 51. At the top end of the inner wall of the sand screening housing 51, two sand dropping port pushers 64 are fixedly connected. The two sand dropping port pushers 64 are arranged close to the sand dropping port 4. A sand dropping port push rod 65 is slidably connected to the side of the sand dropping port pusher 64 close to the sand dropping port 4. A sand dropping port baffle 66 is arranged on the side of the sand dropping port push rod 65 away from the sand dropping port pusher 64.
[0039] Specifically, by driving the blocking pusher 61 to drive the blocking push rod 62 to slide upward, the blocking plate 63 is lifted, so that the processed sand pellets inside the sand screening housing 51 are discharged through the discharge port 52 and re-enter the sand inlet 22 for processing the metal casting. When the blocking push rod 62 slides downward, the blocking plate 63 descends so that the sand pellets inside the sand screening housing 51 cannot flow out, which is convenient for processing. By driving the two sand dropping port pushers 64, the sand dropping port push rod 65 slides, driving the sand dropping port baffle 66 to separate, so that the sand pellets to be processed inside the sand dropping port 4 enter the sand screening housing 51. After a certain amount of sand pellets to be processed enter the sand screening housing 51, the sand dropping port pusher 64 drives the sand dropping port push rod 65 to slide so that the sand dropping port baffle 66 closes, and the sand pellets to be processed are subjected to impurity removal treatment by the device arranged inside the sand screening housing 51.
[0040] The working principle of a surface sandblasting treatment device for metal castings provided by the present utility model is as follows:
[0041] The sand pellets to be processed after the metal casting is processed are guided into the sand dropping port 4 through the sand collecting hopper 25. When the two sand dropping port pushers 64 drive the sand dropping port push rod 65 to slide, driving the sand dropping port baffle 66 to separate, the sand pellets to be processed inside the sand dropping port 4 enter the sand screening housing 51. After a certain amount of sand pellets to be processed enter the sand screening housing 51, the sand dropping port pusher 64 drives the sand dropping port push rod 65 to slide so that the sand dropping port baffle 66 closes. The high-pressure gas with controlled flow rate is sprayed into the sand screening housing 51 through the air spraying pipe 53 inside the sand screening housing 51. The sand pellets inside the sand screening housing 51 are relatively heavy and will not be blown upward by the high-pressure gas, while the metal debris with relatively light mass, generally in the shape of thin sheets or other irregular shapes, is easily blown upward by the gas. Through the impurity outlet 54 for air extraction, the debris is blown out of the sand screening housing 51, and the processed sand pellets are discharged from the discharge port 52, realizing the reuse of the sand pellets.
[0042] Obviously, the above-described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
