Description

Technical Field

[0001] This utility model belongs to the field of shot blasting machine technology, and in particular relates to a shot blasting and rust removal device for pretreatment of steel plates. Background Technology

[0002] Shot blasting is a machine tool that uses shot to strengthen the surface of workpieces. It is an important piece of equipment widely used in industries such as machinery manufacturing, automobiles, and tractors. The shot blasting cleaning process uses the friction between the high-speed shot propelled by the shot blaster and the workpiece to remove the rust layer and dirt on the workpiece surface. Due to the impact and cutting of the shot and the grinding action of the abrasive, an oxide scale with high hardness and a certain thickness is formed on the inner and outer surfaces of the workpiece.

[0003] Chinese Patent Application No. 2019215096734, entitled "A Shot Blasting Machine for Rust Removal Pretreatment of Steel Plates," includes a processing box. A conveying fixing plate is fixedly installed on the inner side of the processing box. Multiple conveying rollers are movably installed on the upper surface of the conveying fixing plate. Motor mounting boxes are fixedly installed on both outer surfaces of the processing box. A lifting conveying bucket is fixedly installed on one outer surface of the processing box, located behind the motor mounting box. A lifting motor is fixedly installed on the upper surface of the lifting conveying bucket. This utility model describes a shot blasting machine for rust removal pretreatment of steel plates. It can rapidly lift and convey steel shot through the rotation of a screw, improving the speed of steel shot recovery and thus increasing the efficiency of steel shot ejection. Furthermore, it can eject steel shot at an angle, allowing for more comprehensive shot blasting treatment of dead corners in the steel plate and preventing areas from being unable to be shot blasted.

[0004] The above patents also have the following shortcomings: during the rust removal process, the steel plate will be strengthened by shot blasting and a lot of impurities will be removed. The impurities will be recycled and thrown out again with the shot, which will damage the surface of the steel plate and affect the shot blasting effect; when the shot is shot at high speed and hits the steel plate, the shot may break. The broken shot will also damage the surface of the steel plate after being recycled. Therefore, this utility model proposes a steel plate pretreatment shot blasting rust removal device to solve the above problems. Utility Model Content

[0005] This utility model provides a shot blasting and rust removal device for steel plate pretreatment, which aims to solve the problems mentioned in the background art.

[0006] This utility model is implemented as follows: a steel plate pretreatment shot blasting and rust removal device, including a shot blasting box, a lifting assembly, a shot blasting assembly, and a shot blasting chamber;

[0007] The bottom surface of the inner wall of the shot blasting box is provided with a slope;

[0008] The lifting assembly is used for rapid lifting and conveying of shot blasting material; the shot blasting assembly is used for shot blasting.

[0009] The shot blasting chamber includes a vibrating motor, which is fitted with a protective box. The protective box is fixedly connected to the ramp. The output end of the vibrating motor is connected to a vibrating box. The bottom surface of the vibrating box is provided with a filter plate. The diameter of the filter holes on the filter plate is smaller than the shot blasting diameter. A leakage hole is opened on the side wall of the vibrating box near the bottom surface. An electric telescopic rod is provided inside the vibrating box. The output end of the electric telescopic rod is connected to a telescopic slider. The telescopic slider is connected to a baffle. The area of ​​the baffle is larger than the area of ​​the leakage hole.

[0010] Preferably, the shot blasting chamber has a front door on its front side, and a control panel is provided on the outer side of the front door.

[0011] Preferably, the bottom of the shot blasting box is provided with four legs arranged in a matrix.

[0012] Preferably, the lifting assembly includes a lifting cylinder located outside the shot blasting chamber. A lifting motor is provided on the top surface of the lifting cylinder, and the output end of the lifting motor is connected to a transmission rod. A lifting screw is provided on the outer wall of the transmission rod. The transmission rod and the lifting screw are accommodated inside the lifting cylinder. A shot blasting conveying pipe is provided on the outer wall of the lifting cylinder, and one end of the shot blasting conveying pipe is connected to the internal space of the lifting cylinder.

[0013] Preferably, the bottom of the lifting cylinder is equipped with support legs, and the lifting cylinder is connected to the interior of the shot blasting box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] After the shot blasting machine is started, the vibrating motor drives the vibrating box to swing. This not only allows the steel plate to better contact the shot, but also filters the shot fragments and rust-removing impurities through the filter plate at the bottom of the vibrating box into the collection box during the swinging process. Because the shot, shot fragments, impurities, and steel plate swing together during the swinging process, and the diameter of the filter holes on the filter plate is smaller than the diameter of the shot, the shot fragments and impurities will fall from the filter plate into the collection box under the action of the swinging force. Since the shot blasting time is usually in the range of 3-15 minutes, after the shot blasting machine has been running for 2-5 minutes, the electric telescopic rod starts to retract, causing the baffle to retract from the leakage hole. At this time, the shot inside the vibrating box will fall to the ramp and flow to the bottom of the lifting cylinder. The lifting component quickly lifts and transports the shot, improving the shot recovery and transportation speed. At the same time, the shot fragments and impurities will be collected, avoiding the problem of excessive shot fragments and impurities causing damage to the surface of the steel plate.

[0032] Please see Figures 1 to 5This utility model provides a technical solution: a shot blasting and rust removal device for steel plate pretreatment, including a shot blasting box 1, a lifting component 2, a shot blasting component 3, and a shot blasting chamber 4; the bottom surface of the inner wall of the shot blasting box 1 is provided with a ramp 11; the lifting component 2 is used for rapid lifting and conveying of shot blasting, and the shot blasting component 3 is used for shot blasting; the shot blasting chamber 4 includes a vibrating motor 41, the vibrating motor 41 is covered with a protective box, the protective box is fixedly connected to the ramp 11, the output end of the vibrating motor 41 is connected to a vibrating box 42, the bottom surface of the vibrating box 42 is provided with a filter plate 43, the diameter of the filter hole on the filter plate 43 is smaller than the shot blasting diameter, a leakage hole 47 is opened on the side wall of the vibrating box 42 near the bottom surface, an electric telescopic rod 44 is provided inside the vibrating box 42, the output end of the electric telescopic rod 44 is connected to a telescopic slider 45, the telescopic slider 45 is connected to a baffle 46, the cross-sectional area of ​​the baffle 46 is larger than the cross-sectional area of ​​the leakage hole 47.

[0033] For further details, please refer to Figure 3 The lifting assembly 2 includes a lifting cylinder 21, which is located outside the shot blasting box 1. A lifting motor 22 is provided on the top surface of the lifting cylinder 21. The output end of the lifting motor 22 is connected to a transmission rod 23. A lifting screw 24 is provided on the outer wall of the transmission rod 23. The transmission rod 23 and the lifting screw 24 are accommodated inside the lifting cylinder 21. A shot blasting conveying pipe 25 is provided on the outer wall of the lifting cylinder 21. One end of the shot blasting conveying pipe 25 is connected to the internal space of the lifting cylinder 21.

[0034] For further details, please refer to Figure 2 The shot blasting assembly 3 includes a shot blasting diversion pipe 31 and a shot blaster 33. The shot blasting diversion pipe 31 is connected to the shot blasting conveying pipe 25. The shot blasting diversion pipe 31 is fixedly installed on the top of the inner wall of the shot blasting box 1. The shot blaster 33 is connected to the shot blasting diversion pipe 31. The shot blaster 33 is driven by the shot blasting motor 32. Multiple shot blasting impellers are installed on the shot blaster 33.

[0035] In this embodiment, the shot blaster 33 is externally connected to a shot blasting container, which contains multiple shot blasting chambers. When the device is needed, the front door of the shot blasting chamber 1 is opened, a steel plate is placed inside the vibration chamber 42, and then the front door is closed. The shot blasting motor 32 is started via the control panel 12. The rotation of the shot blasting motor 32 drives the shot blaster 33 to rotate, which in turn drives the shot blasting impeller to rotate, thereby propelling the shot blasting chamber 33 at high speed towards the vibration chamber 42. The shot blaster 33 is connected to the shot blasting container, and the shot blasting chamber automatically falls into the shot blaster 33. When the shot blasting chamber is propelled into the vibration chamber 42, the shot blasting process is complete. After entering the vibrating box 42, shot blasting is performed on the surface of the steel plate inside the vibrating box 42 to remove rust. At this time, the vibrating motor 41 is started, and the vibration of the vibrating motor 41 drives the vibrating box 42 to swing. This not only allows the steel plate to better contact the shot, but also filters the shot fragments and rust removal impurities through the filter plate 43 at the bottom of the vibrating box 42 into the collection box 48 during the swinging process. Because the shot, shot fragments, impurities and steel plate swing together during the swinging process, and the diameter of the filter holes on the filter plate 43 is smaller than the diameter of the shot, the shot fragments and impurities will fall from the filter plate 43 into the collection box 48 under the action of the swinging force. Due to the shot blasting rust removal process... The time is usually within the range of 3-15 minutes. 2-5 minutes after the shot blaster 33 starts, the electric telescopic rod 44 retracts, causing the baffle 46 to retract from the vent hole 47. At this time, the shot inside the vibrating box 42 falls onto the ramp 11, flowing towards the bottom of the lifting cylinder 21. Then, the lifting motor 22 is started, driving the transmission rod 23 and the lifting screw 24 to rotate. The rotation of the lifting screw 24 rapidly transports the shot from the bottom of the lifting cylinder 21 upwards. When it reaches the top of the lifting cylinder 21, it falls into the shot blasting conveying pipe 25, and then further through the pipe... Inside the shot blasting diversion pipe 31, the shot falls back onto the inside of the shot blaster 33, and the shot blasting process is repeated. When the shot blasting motor 32 drives the shot blaster 33 to rotate and blast, the two shot blasting motors 32 and the shot blaster 33 are installed at a symmetrical angle. Therefore, the shot is also thrown at an angle. The shot thrown at an angle can more comprehensively blast the dead corners of the steel plate. After the shot blasting is completed, the electric telescopic rod 44 is activated to extend and drive the baffle 46 to block the leakage hole 47. Then the power is turned off, the steel plate is collected, the shot is collected, and finally the broken shot and impurities are collected and processed.

[0036] The above methods can filter out some of the shot fragments and impurities, preventing the proportion of shot fragments and impurities in the shot blasting process from being too high, which would affect the rust removal of the steel plate surface and avoid damage to the steel plate surface caused by excessive shot fragments and impurities.

[0037] For further details, please refer to Figure 1 The shot blasting box 1 has a front door on its front side, and a control panel 12 is located on the outer side of the front door.

[0038] In this embodiment, the control panel 12 can control the power supply to and from the lifting motor 22, shot blasting motor 32, vibration motor 41 and electric telescopic rod 44.

[0039] For further details, please refer to Figure 1 The bottom of the shot blasting box 1 is provided with four support legs 13 arranged in a matrix.

[0040] For further details, please refer to Figure 1 The bottom of the lifting cylinder 21 is equipped with support legs 13, and the lifting cylinder 21 is connected to the inside of the shot blasting box 1.

[0041] In this embodiment, the four support legs 13 arranged in a matrix can provide support and stability to the shot blasting box 1; the support legs 13 at the bottom of the lifting cylinder 21 can provide support and stability to the lifting cylinder 21.

[0042] The working principle and usage process of this utility model are as follows: When the device is needed, open the front door of the shot blasting box 1, place the steel plate inside the vibration box 42, and then close the front door. Control the start of the shot blasting motor 32 via the control panel 12. The rotation of the shot blasting motor 32 drives the shot blaster 33 to rotate, which in turn drives the shot blasting impeller to rotate, thus propelling the shot in the shot blaster 33 at high speed towards the vibration box 42. The shot blaster 33 is connected to the shot blasting container, and the shot in the container automatically falls into the shot blaster 33. After the shot is ejected and falls into the vibration box 42, the interior of the vibration box 42... Shot blasting is performed on the surface of the steel plate to remove rust. At this time, the vibrating motor 41 is started, and the vibration of the vibrating motor 41 drives the vibrating box 42 to swing. This not only allows the steel plate to better contact the shot, but also filters the shot fragments and rust-removing impurities through the filter plate 43 at the bottom of the vibrating box 42 into the collection box 48 during the swinging process. Because the shot, shot fragments, impurities, and steel plate swing together during the swinging process, and the diameter of the filter holes on the filter plate 43 is smaller than the diameter of the shot, the shot fragments and impurities will fall from the filter plate 43 into the collection box 48 under the action of the swinging force. Since the shot blasting time is usually 3-15 minutes... Within the specified range, after the shot blaster 33 has been running for 2-5 minutes, the electric telescopic rod 44 retracts, causing the baffle 46 to retract from the vent hole 47. At this time, the shot inside the vibrating box 42 falls onto the ramp 11 and flows to the bottom of the lifting cylinder 21. Then, the lifting motor 22 is started, driving the transmission rod 23 and the lifting screw 24 to rotate. Through the rotation of the lifting screw 24, the shot is quickly conveyed from the bottom of the lifting cylinder 21 upwards. When it reaches the top of the lifting cylinder 21, it falls into the shot blasting conveying pipe 25 and then into the shot blasting distribution pipe. Inside channel 31, the shot falls again into the inner side of shot blaster 33 through shot blasting diversion pipe 31, and shot blasting is carried out in a cycle. When shot blasting motor 32 drives shot blaster 33 to rotate and blast, the two shot blasting motors 32 and shot blaster 33 are installed at a symmetrical angle. Therefore, the shot is also thrown at an angle. The shot thrown at an angle can more comprehensively blast the dead corners of the steel plate. After shot blasting is completed, the electric telescopic rod 44 is activated to extend and drive the baffle 46 to block the leakage hole 47. Then the power is turned off, the steel plate is collected, the shot is collected, and finally the broken shot and impurities are collected and processed.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
