Description

Technical Field

[0001] This utility model relates to the field of steel structure production technology, and in particular to a shot blasting device for steel structures. Background Technology

[0002] The main reason for using shot blasting machines in steel structure production is to remove rust and scale from the steel surface, thereby improving the coating quality and corrosion resistance. Shot blasting machines effectively remove surface rust, scale, and dirt by spraying steel balls or iron shot at high speed onto the steel surface, resulting in a uniform metallic luster.

[0003] Chinese patent CN221696567U discloses a shot blasting device for steel structure production. This device, by incorporating a drive cylinder, dust filter, dust suction pipe, and dust collection box, solves the problem that existing shot blasting devices easily generate iron filings and dust when steel shot impacts the surface of steel structures, affecting the working environment and causing continuous damage to the lungs when inhaled. Through the combination of the above structures, the shot blasting device can absorb the dust generated by the internal impact during use, effectively reducing the dust from spreading everywhere, improving the working environment, and preventing the dust from being inhaled into the lungs.

[0004] However, the device still has shortcomings: it occupies a large space and cannot rotate or reposition the workpiece during the workpiece transport process, so the workpiece cannot be polished in all directions without dead angles in one pass. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a steel structure shot blasting device.

[0006] The technical solution of this utility model is: a steel structure shot blasting device, including a frame, a cylindrical tube with an inlet and outlet on the side of the frame, and a plurality of shot blasters on the cylindrical tube; The storage tank is mounted on the machine frame, and its output end is connected to the input end of each shot blaster. The feeding pipe has its input end connected to the lower opening of the cylindrical tube. A filter screen is installed at an incline inside the feeding pipe. An outlet pipe connected to the inside of the feeding pipe is installed on the feeding pipe, with the filter screen tilted towards the input end of the outlet pipe. The feeding assembly is mounted on the frame and connects the output end of the discharge pipe and the input end of the storage tank. The cylinder cover is sealed to the upper end of the cylindrical tube. A turntable that rotates coaxially with the bottom of the cylinder cover is provided. Several partitions are arranged in a ring array around the bottom of the cylinder cover to form several non-interconnected compartments inside the cylindrical tube. Each compartment has a hook at its top that is connected to the turntable for rotation. And the drive mechanism, which is located on the cylinder cover, drives the hook to rotate while following the turntable in the working state.

[0007] Preferably, a guide plate is provided inside the feed pipe, the guide plate is located above the filter screen, and the guide plate is tilted towards the higher end of the filter screen.

[0008] Preferably, the feeding assembly includes a screw conveyor, the feed end of which is connected to the output end of the discharge pipe, and the output end of the screw conveyor is provided with an inclined pipe, the output end of which is inserted into the storage tank.

[0009] Preferably, a central shaft is coaxially arranged on the turntable, the central shaft is rotatably connected to the cylinder cover, one end of the partition plate is connected to the central shaft, and a support plate is arranged inside the lower channel of the cylindrical cylinder, with the central shaft rotatably connected to the support plate.

[0010] Preferably, a drive shaft is provided at the top of the hook, the drive shaft is rotatably connected to the turntable, and the drive shafts are arranged in a ring array around the center of the turntable.

[0011] Preferably, the drive mechanism includes a transmission component and a motor. The transmission component includes gears and an internal gear ring. The number of gears is the same as the number of transmission shafts, and each gear is coaxially connected to the corresponding transmission shaft. The internal gear ring is coaxially connected to the cylinder cover, and each gear meshes with the internal gear ring. The motor body is connected to the cylinder cover, and the motor output end is connected to the turntable.

[0012] Preferably, a water storage tank and a blower are installed on the frame, the lower end of the feed pipe is inserted into the water storage tank and located below the liquid surface, the output end of the blower is connected to the outside, and an air extraction pipe is installed at the input end of the blower. The other end of the air extraction pipe is inserted into the water storage tank and located above the liquid surface.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: By using a vertical frame and a horizontal cylindrical structure, the space occupied by the equipment can be reduced. Multiple shot blasters are installed on the cylindrical tube, and a structure with a turntable, partition, and hooks is installed on the tube cover. A drive mechanism consisting of gears, internal gear rings, and a motor is also installed. When the motor drives the turntable to rotate, the workpiece hanging on the hooks revolves with the turntable, and the workpiece also rotates on its own axis under the transmission of gears and gear rings. This changes the position of the workpiece towards the exit of the shot blaster while it is rotating, thereby achieving the purpose of rapid and all-round grinding. At the same time, this device is also equipped with a screw conveyor, a water tank, and a fan to facilitate the separation of shot and debris and other impurities, and to allow the shot to be reintroduced into the storage tank for recycling.

[0016] Example 1 like Figures 1-4As shown, this utility model proposes a steel structure shot blasting device, including a frame 1, a storage tank 4, a feeding pipe 6, a feeding assembly, a cylinder cover 12, and a drive mechanism. A cylindrical tube 2 with an inlet / outlet 201 on its side is mounted on the frame 1, and several shot blasters 3 are mounted on the cylindrical tube 2. The storage tank 4 is mounted on the frame 1, and a distributor is installed at the output end of the storage tank 4. The distributor includes several outlets, each with a guide pipe 5. The output end of each guide pipe 5 is connected to the input end of the corresponding shot blaster 3. The input end of the feeding pipe 6 is connected to the lower opening of the cylindrical tube 2. A filter screen 7 is inclinedly installed inside the feeding pipe 6, and a discharge pipe 9 connected to the inside of the feeding pipe 6 is installed on the feeding pipe 6, with the filter screen 7 inclined towards the input end of the discharge pipe 9. A guide plate 8 is installed inside the feeding pipe 6, located above the filter screen 7, and inclined towards the higher end of the filter screen 7. The feeding assembly is mounted on the frame 1 and connects to the output end of the discharge pipe 9 and the input end of the storage tank 4. The feeding assembly includes a screw conveyor 10, whose inlet end is connected to the output end of the discharge pipe 9. An inclined pipe 11 is installed at the output end of the screw conveyor 10, and the output end of the inclined pipe 11 is inserted into the storage tank 4. A cylinder cover 12 is sealed to the upper end of the cylindrical cylinder 2. A turntable 13, coaxially rotating with the bottom of the cylinder cover 12, is installed in a circular array around its axis at the bottom of the cylinder cover 12, forming several non-communicating compartments within the cylindrical cylinder 2. The bottom of each compartment is connected to the input end of the discharge pipe 6. Each compartment has a hook 16 at its top, rotatably connected to the turntable 13. A drive shaft 15 is installed at the top of the hook 16, rotatably connected to the turntable 13, and the drive shafts 15 are arranged in a circular array around the center of the turntable 13. A central shaft is coaxially mounted on the turntable 13, and the central shaft is rotatably connected to the cylinder cover 12. One end of the partition plate 14 is connected to the central shaft, and a support plate 202 is provided inside the lower channel of the cylindrical cylinder 2. The central shaft is rotatably connected to the support plate 202. A drive mechanism is mounted on the cylinder cover 12. In operation, the drive mechanism drives the hook 16 to rotate along with the turntable 13 while simultaneously causing the hook 16 to rotate on its own axis. The drive mechanism includes a transmission assembly and a motor 19. The transmission assembly includes gears 17 and an internal gear ring 18. The number of gears 17 is the same as the number of transmission shafts 15, and each gear 17 is coaxially connected to the corresponding side of the transmission shaft 15. The internal gear ring 18 is coaxially connected to the cylinder cover 12, and each gear 17 meshes with the internal gear ring 18. The motor 19 is connected to the cylinder cover 12. The motor 19 is a servo motor, and its output end is connected to the turntable 13.

[0017] In this embodiment, the workpiece is placed into the compartment from the inlet / outlet 201 and hung on the hook 16. The motor 19 is started, and the motor 19 drives the turntable 13 to rotate. At this time, the workpiece rotates and changes position with the turntable 12. When the workpiece rotates to the outlet of the shot blaster, the shot blaster 3 is started, thereby shot blasting the surface of the workpiece. As the turntable 13 rotates, the workpiece rotates under the action of the gear 17 and the internal gear ring 18, thereby changing its position toward the outlet of the shot blaster 3. The workpiece revolves around the central axis of the turntable 13 while rotating, so that each surface can be polished when it passes through each shot blaster 3. During the polishing process, the shot is blocked by the partition 14 and can only fall downward into the feed pipe 6. Fine debris and other impurities are filtered through the filter screen 7. The shot rolls into the discharge pipe 9 along the filter screen 7 and enters the storage pipe 4 under the lifting action of the screw conveyor 10.

[0018] Example 2 like Figure 1 As shown, the steel structure shot blasting device proposed in this utility model, compared with Embodiment 1, has a water storage tank 20 and a blower 21 installed on the frame 1. The lower end of the feed pipe 6 is inserted into the water storage tank 20 and located below the liquid surface. The output end of the blower 21 is connected to the outside, and the input end of the blower 21 is equipped with an exhaust pipe 22. The other end of the exhaust pipe 22 is inserted into the water storage tank 20 and located above the liquid surface. The water storage tank 20 is equipped with a feed pipe and a drain pipe that communicate with its interior. The feed pipe is equipped with a cap, and the drain pipe is equipped with a valve to control the opening and closing of its interior.

[0019] In this embodiment, the blower 21 draws air from the water storage tank 20 to create a negative pressure environment inside the water storage tank 20, thereby allowing air and dust from the feed pipe 6 to enter the water storage tank 20. After the dust comes into contact with the water, it separates from the air, and the air is discharged. This structure is beneficial to further improve the efficiency of separating dust and small impurities from the shot.

[0020] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
