Description

Technical Field

[0001] The utility model belongs to the technical field of shot blasting machines, and particularly relates to a cleaning device for a steel bar shot blasting machine. Background Technique

[0002] A steel bar shot blasting machine is a device used for the surface treatment of steel bars. By means of a high-speed rotating shot blasting device, steel shots or other particulate matters are sprayed onto the surface of the steel bars, so as to remove rust, dirt and oxide layers on the surface of the steel bars. At the same time, the surface quality of the steel bars is improved, and its corrosion resistance and mechanical strength are enhanced.

[0003] After the steel bars are derusted by the steel bar shot blasting machine, there may be residual rust debris and a small amount of particulate matters used for derusting on their surfaces. For this reason, as disclosed in a cleaning device for a steel bar derusting shot blasting machine with the application number CN201921724454.8, it includes a fixed box fixedly arranged on the shot blasting machine body. The fixed box is communicated with the inside of the shot blasting machine body. A cleaning component is detachably connected in the fixed box. The cleaning component includes a positioning plate arranged in the fixed box. A through hole is opened in the middle of the positioning plate. A circular rubber pad is arranged at the through hole of the positioning plate. The rubber pad is radially divided into multiple petals from the central position outwards. The steel bar passes through the center of the rubber pad. It uses the rubber pad to scrape off the rust and iron sand on the surface of the steel bar, prevents the rust debris and iron sand from flowing out of the shot blasting machine body along with the steel bar, cleans the steel bar more cleanly, and can also reduce the waste of iron sand.

[0004] In this technical solution, when the steel bar passes through the central position of the rubber pad, the central part of the rubber pad will deform towards the discharge direction by the steel bar, and there will be a gap between two adjacent petals of the rubber pad. It is difficult for the rubber pad to fully contact the side surface of the steel bar. Moreover, after the central part of the rubber pad is set into multiple petals, the resilience of the central part of the rubber pad will be weakened, and it may be difficult to effectively scrape off the residual debris and particulate matters on the surface of the steel bar. Therefore, there is still room for improvement. Content of the Utility Model

[0028] Embodiment 1: As Figures 1 to 3As shown in the figure, a cleaning device for a steel bar shot blasting machine includes a shot blasting machine body 1. An outlet 11, a pipe body 2, and an inlet 12 located directly below the outlet 11 are provided on the side of the shot blasting machine body 1. One end of the pipe body 2 is communicated with the outlet 11, and the other end of the pipe body 2 is provided with an end cap 3. A through hole 31 coaxial with the outlet 11 is provided on the end cap 3. An outlet 2121 and a plurality of air spray guns 4 are provided on the side of the pipe body 2. The outlet 2121 is connected to the inlet 12 through a connecting pipe 5, and the air spray guns 4 extend into the pipe body 2.

[0029] The steel bars output from the outlet 11 of the shot blasting machine body 1 enter the pipe body 2. The rust debris and particulate matter on the surface of the steel bars are cleaned by jetting air through the air spray guns 4. After cleaning, the steel bars are output through the through hole 31, and the rust debris and particulate matter return to the inside of the shot blasting machine body 1 through the outlet 2121, the connecting pipe 5, and the inlet 12 for convenient later cleaning.

[0030] Embodiment Two: As Figures 2 to 4 shown in the figure, the rest is the same as Embodiment One, and the difference is that the pipe body 2 includes four side plates 21 and four inclined plates 22 distributed along the circumferential direction. Adjacent two side plates 21 are connected by one inclined plate 22. The air spray guns 4 are arranged on the inclined plates 22, and the outlet 2121 is arranged on the lower side plate 21. Further, the cross-section of the pipe body 2 is a regular octagon. The four side plates 21 are respectively an upper side plate 211, a lower side plate 212, a left side plate 213, and a right side plate 214. The outlet 2121 is arranged on the lower side plate 212. Transparent observation windows 23 are respectively arranged on the upper side plate 211, the left side plate 213, and the right side plate 214. The design of this structure facilitates the rust debris and particulate matter to gather on the lower side plate 212 and finally return to the inside of the shot blasting machine body 1 through the outlet 2121, the connecting pipe 5, and the inlet 12. The air spray guns 4 can clean the steel bars in all directions, and the staff can directly view the cleaning status through the observation windows 23.

[0031] In this embodiment, a first mounting hole 221 corresponding to the air spray gun 4 is provided on the inclined plate 22. The air spray gun 4 includes a gun body 41 and a gun barrel 42. The gun body 41 is fixedly arranged on the outer side surface of the pipe body 2, and the gun barrel 42 extends into the pipe body 2 after passing through the corresponding first mounting hole 221.

[0032] In this embodiment, four air spray guns 4 are provided, and one air spray gun 4 is respectively arranged on each inclined plate 22.

[0033] Embodiment Three: As Figures 2 to 4 shown in the figure, the rest is the same as Embodiment Two, and the difference is that eight air spray guns 4 are provided, and two air spray guns 4 are respectively arranged on each inclined plate 22, which helps to improve the cleaning efficiency.

[0034] In this embodiment, the two air spray guns 4 of the same inclined plate 22 are distributed along the length direction of the tube body 2. The barrel 42 of the air spray gun 4 near one end of the tube body 2 is inclined from the outside to the inside and toward the direction of the discharge port 11, and the barrel 42 of the air spray gun 4 near the other end of the tube body 2 is inclined from the outside to the inside and toward the direction of the through hole 31. This can make the airflow cover the surface of the steel bar more widely and effectively blow away rust fragments and particulate matter from different areas of the steel bar surface, thereby improving the overall cleaning efficiency. In addition, by forming an inclined airflow, rust fragments and particulate matter can be more easily guided toward the outlet 2121 of the lower plate 212, thereby reducing the retention of rust fragments and particulate matter inside the tube body 2 and avoiding accumulation.

[0035] In this embodiment, a second mounting hole 222 is provided on the inclined plate 22, and the second mounting hole 222 is located between the air spray gun 4 and the discharge port 11. A brush 6 is inserted at the second mounting hole 222, and the head of the brush 6 extends into the tube body 2. The brush 6 plays an auxiliary cleaning role, using physical contact to help scrape off rust debris and particles. Compared with the rubber pad, it can more fully contact with the steel bar and has a better cleaning effect. Since the brush 6 is arranged between the air spray gun 4 and the discharge port 11, even if the brush 6 is worn out, the impurities it produces have little impact and can be quickly cleaned by the air spray gun 4.

[0036] Embodiment 4: Figures 2 to 4 As shown, the rest of the parts are the same as those of Example 3, with the difference being that the second mounting hole 222 is a threaded hole, the brush 6 includes a rod body 61 and bristles 62 arranged at one end of the rod body 61, the side of the rod body 61 is provided with an external thread, the rod body 61 is threadedly matched with the second mounting hole 222, and one end of the rod body 61 extends into the tube body 2. The design of this structure can flexibly adjust the length of the brush 6 extending into the inside of the tube body 2 to adjust the cleaning force of the brush 6, and has good flexibility.

[0037] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
