Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for shot blasting machines, specifically a dust collector for shot blasting machines. Background Technology

[0002] In industries such as metal processing and casting, shot blasting machines are key equipment for surface treatment. They use high-speed shot streams to impact and clean workpieces, generating a large amount of dust-laden exhaust gas while achieving high efficiency. This dust-laden exhaust gas contains solid impurities such as metal particles and oxide scale. If discharged directly without effective treatment, it will lead to increased dust concentration in the workshop, directly threatening the health of operators and polluting the surrounding environment. To address this pressing problem, baghouse dust collectors, through their primary and secondary dust filtration mechanisms formed on the surface of the filter bags, can accurately intercept tiny particles in the dust-laden exhaust gas, thus achieving gas-solid separation and finding wide application in industrial dust removal.

[0003] However, existing dust collectors for shot blasting machines have certain technical defects in actual use. Specifically, when cleaning the filter bags, most dust collectors use pulse cleaning, but this cleaning method often leaves a small amount of impurities attached and remaining, resulting in incomplete cleaning and affecting the long-term stable operation and dust removal efficiency of the dust collector. At the same time, when discharging the filtered debris, blockages are prone to occur due to unreasonable bottom structural design or narrow debris discharge channels. This not only affects the normal debris discharge function of the dust collector, but also prevents the filtered debris from being discharged smoothly, causing great inconvenience to subsequent impurity collection and treatment. Utility Model Content

[0004] The purpose of this invention is to provide a dust collector for shot blasting machines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust collector for a shot blasting machine, comprising a shot blasting machine body and a dust collector body. The shot blasting machine body is connected to the input end of the dust collector body via a collection pipe. An exhaust pipe is provided on the side wall of the dust collector body, and a discharge pipe is provided at the bottom end of the dust collector body. Filter bags are equidistantly arranged inside the dust collector body via a rotating assembly. A drive assembly is provided at the top center of the dust collector body, and a cleaning and conveying assembly matching the filter bags is provided in the center of the dust collector body. Both the rotating assembly and the cleaning and conveying assembly are connected to the drive assembly.

[0006] Preferably, in order to facilitate the subsequent rotation of the filter bag body by the drive component and to cooperate with the cleaning brush to clean the surface again, the rotating component includes a mounting plate set inside the dust collector body. The mounting plate has equidistant circular holes, and the circular holes are connected to the filter bag body through bearings.

[0007] Preferably, in order to ensure the stability of the filter bag body during rotation and to play a guiding and limiting role, the inner side wall of the dust collector body is provided with arc-shaped guide rings at equal intervals, and the bottom circumferential side of the filter bag body is provided with an annular guide groove that matches the arc-shaped guide rings. The arc-shaped guide rings are fixedly connected to the inside of the filter bag body through a connecting rod.

[0008] Preferably, in order to facilitate the conveying and discharge of the waste collected by the filter and avoid blockage, the cleaning and conveying assembly includes a rotating rod rotatably disposed in the middle of the mounting plate, and a spiral conveying blade is provided at the bottom end of the rotating rod, the spiral conveying blade being matched with the discharge pipe.

[0009] Preferably, in order to clean the periphery of the bag body and avoid impurities, the cleaning and conveying assembly also includes a connector fixedly installed at the bottom center of the mounting plate. The connector is rotatably connected to the rotating rod. A cleaning roller is fixedly installed under the connector, and cleaning bristles are provided on the periphery of the cleaning roller.

[0010] Preferably, in order to facilitate the rotation of the bag body and the rotating rod, so as to clean on the one hand and assist in the discharge of collected debris on the other hand, the drive component includes a motor set at the top of the dust collector body, the output end of the motor is connected to the rotating rod, the output end of the motor is provided with a main gear, and a driven gear meshes with the peripheral side of the main gear. The driven gear corresponds one-to-one with the bag body, and the driven gear is connected to the bag body through a connecting component.

[0011] Preferably, in order to facilitate cleaning of the bag body, the connecting assembly includes a connecting platform set on the top of the bag body, a rotating shaft fixedly provided at the top of the connecting platform, the rotating shaft passing through the dust collector body and connected to the driven gear, and through holes communicating with the bag body are equidistantly opened on the periphery of the connecting platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Through the linkage design of the rotating component and the cleaning and conveying component, the filter bag body can achieve dynamic rotation. Combined with the continuous cleaning action of the cleaning brush, it effectively removes residual impurities from the surface of the filter bag, avoiding the local dust accumulation problem that is easily caused by traditional pulse cleaning methods. This significantly improves dust removal efficiency and filter bag life. The matching design of the spiral conveying blades and the discharge pipe in the cleaning and conveying component enables the active spiral conveying of debris under the drive component. This effectively prevents the discharge pipe from clogging, ensures that debris is discharged quickly and stably, and reduces the frequency of manual maintenance.

[0014] The drive assembly adopts a meshing transmission structure of main gear and driven gear to realize the dual functions of rotating the main body of the bag and rotating the spiral conveyor blades under the drive of a single motor. This simplifies the power transmission path, reduces equipment energy consumption and manufacturing costs, and ensures the synchronization and coordination of the operation of each component.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figures 1-5This utility model provides an embodiment of a dust collector for a shot blasting machine, comprising a shot blasting machine body 11, which is used for shot blasting workpieces. The debris generated during the shot blasting process is connected to the input end of the dust collector body 12 via a collection pipe 13 for convenient collection and unified processing. An exhaust pipe 14 is provided on the side wall of the dust collector body 12, and a discharge pipe 15 is provided at the bottom end of the dust collector body 12 for convenient unified discharge of the collected debris. Inside the dust collector body 12, filter bag bodies 32 are equidistantly arranged via a rotating assembly. The number of filter bag bodies 32 can be 4-8 sets. Groups 4, 5, 6, 7, and 8 are preferred, with group 4 being the most suitable. This ensures effective dust collection and is a relatively mature technology, so it will not be elaborated upon here. The dust collector body 12 has a drive assembly at the top center and a cleaning and conveying assembly matching the filter bag body 32 in the center of the dust collector body 12. Both the rotating assembly and the cleaning and conveying assembly are connected to the drive assembly. To ensure the cleaning effect on the filter bag body 32, a pulse dust collector (not shown in the figure) is installed on the dust collector body 12. It uses compressed air to instantly blow the filter bag, and combined with the Venturi effect, forms a reverse airflow to peel off the dust layer on the surface of the filter bag. This is a relatively mature technology, so it will not be elaborated upon here.

[0023] Please see Figures 1-5 To improve the cleaning effect of the filter bag body 32, prevent adsorbed impurities from adhering and remaining, and ensure that it does not affect subsequent dust collection, thereby improving the dust collection effect and ensuring thorough cleaning, the filter bag body 32 is installed inside the dust collector via a rotating assembly. The rotating assembly includes a mounting plate 31 located inside the dust collector body 12. The mounting plate 31 has equidistant circular holes, and the filter bag body 32 is connected to the circular holes via bearings. The filter bag body 32 can rotate axially at the center of the circular holes. To ensure stability during rotation, a limiting guide can be provided, allowing rotation along the central axis of the filter bag body 32. The inner sidewall of the dust collector body 12 is provided with equidistant arc-shaped guide rings 52, and the bottom circumferential side of the filter bag body 32 has an annular guide groove 53 that matches the arc-shaped guide rings 52. The arc-shaped guide ring 52 is fixedly connected to the inside of the bag body 32 via the connecting rod 51. In order to assist in the discharge during cleaning and avoid blockage, a cleaning and conveying assembly is provided inside the dust collector body 12. The cleaning and conveying assembly includes a rotating rod 41 rotatably disposed in the middle of the mounting plate 31. The bottom end of the rotating rod 41 is provided with a spiral conveying blade 42, which matches the discharge pipe 15. The cleaning and conveying assembly also includes a connector 62 fixedly disposed in the middle of the bottom end of the mounting plate 31. The connector 62 is rotatably connected to the rotating rod 41. A cleaning roller 61 is fixedly disposed below the connector 62. The cleaning roller 61 has cleaning bristles 63 on its circumferential side, which are soft bristles, so as to facilitate cleaning of the circumferential side of the bag body 32 while avoiding hard contact and damage to the bag body 32.

[0024] Please see Figures 1-5To facilitate the rotation of the spiral conveyor blades 42 for material feeding and to facilitate the rotation of the filter bag body 32 for cleaning the surrounding sides of the filter bag body 32, a drive assembly is provided on the dust collector body 12. The drive assembly includes a motor 21 located at the top of the dust collector body 12. The output end of the motor 21 is fixedly connected to the rotating rod 41 via a coupling. The output end of the motor 21 is provided with a main gear 22. A driven gear 23 meshes with the circumferential side of the main gear 22. Preferably, there are 4 sets of driven gears 23, each corresponding to one of the filter bag bodies 32. The driven gears 23 are connected to the filter bag body 32 via a connecting assembly. The connecting assembly includes a frustum-shaped connecting platform 33 located at the top of the filter bag body 32. A rotating shaft 24 is fixedly connected to the top of the connecting platform 33. The rotating shaft 24 passes through the dust collector body 12 and is connected to the driven gear 23. Through holes 34, which communicate with the filter bag body 32, are equidistantly opened on the circumferential side of the connecting platform 33, so as not to affect the passage of filtered gas and its discharge through the exhaust pipe 14.

[0025] Working Principle: In operation, when the shot blasting machine body 11 performs shot blasting on the workpiece, the generated debris is collected through the collection pipe 13 and enters the dust collector body 12. There, it is filtered by the filter bag body 32. The filtered gas passes through the through hole 34 and then exits through the exhaust pipe 14. When the filter bag body 32 needs cleaning, it can be cleaned by pulse dust collector blowing (not shown in the diagram). When the collected debris needs to be discharged, the motor 21 rotates, causing the rotating rod 41 to rotate, and the spiral conveyor blades 4... 2. Rotation assists in material feeding, which is discharged through the discharge pipe 15 for easy collection and to avoid blockage. During the rotation of motor 21, main gear 22 rotates along with it, and driven gear 23 rotates accordingly, causing the connecting platform 33 under the rotating shaft 24 and the bag body 32 to rotate within the circular hole. With the help of annular guide groove 53 and arc-shaped guide ring 52, the rotation of bag body 32 can be stabilized and guided. At this time, with the help of cleaning brush bristles 63 on the side of cleaning roller 61, the side of bag body 32 can be cleaned again to ensure the cleaning effect.
