Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting, in particular to a sandblasting angle adjustment mechanism. Background Art

[0002] When the boiler is mixed with industrial waste, due to the high content of alkali metal elements such as sodium and potassium in the ash and the low ash melting point, it is easy to form ash accumulation with strong adhesion on the heating surface of the rear end of the boiler, reducing the thermal efficiency of the boiler and affecting the long-term operation of the boiler. Although the shock wave soot blowing method is currently generally adopted for the heating surface of the rear end of the boiler, the soot blowing effect is not very significant. Therefore, sand blasting is used to clean the ash, but the existing sand blasting angle is reflected by the baffle, and the angle of the baffle is often fixed, resulting in a limited range. Improvements are proposed in this regard. Utility Model Content

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 3 The sandblasting angle adjustment mechanism includes a baffle 2, which slides inside the boiler through a rod body 3 in the middle. The rod body 3 slides in the boiler flue 1 to control the movement of the control rod 4 and the position of the baffle 2 to adjust the sandblasting angle.

[0017] Furthermore, in order to increase the reflective sandblasting interval, control rods 4 are provided on both sides of the rod body 3, and the control rod 4 also slides in the boiler flue 1. A rack 5 is configured on the opposite side of the control rod 4, that is, the direction of the teeth of the rack 5 is arranged toward the rod body 3, and a half gear 6 is installed in the middle of the rod body 3. The half gear 6 has a gear with half the circumference. When the half gear 6 continuously rotates in the same direction, when the upper rack 5 is driven, the lower one remains stationary, and vice versa, so that the control rod 4 realizes reciprocating movement.

[0018] It can be seen that the middle part of the baffle 2 is rotatably connected to the rod body 3, so the control rod 4 continuously rotates back and forth alternately to realize the rotation of the baffle 2. Furthermore, in order to ensure the sealing of the boiler flue 1 during sandblasting, the rod body 3 and the control rod 4 are connected to the hole 8 of the boiler flue 1, and a sealing ring is provided in the hole 8. The sealing ring ensures the sealing of the rod body 3 and the control rod 4 when they move.

[0019] At the same time, the control rod 4 is connected to the end of the rod body 3 through a spring 7. Specifically, a connecting plate 9 is provided on the end of the rod body 3, and a guide rod 10 with a diameter smaller than the main body is provided at the end of the control rod 4. The spring 7 is connected between the connecting plate 9 and the control rod 4. At the same time, the guide rod 10 passes through the spring 7 and slides in the connecting plate 9. The spring 7 ensures buffering and recovery during the movement, and can also quickly reset another set of control rods 4 when the half gear 6 is working.

[0020] As for the half gear 6, it is directly connected to the motor, and the drive of the motor provides reliable rotational force, making the rotation of the half gear 6 more efficient and stable. Further, the rod body 3 is mostly an output shaft of an electric push rod or a hydraulic push rod, which can provide the movement of the baffle 2 as a whole.

[0021] In summary, this embodiment uses the non-use nozzle 11 angle to control the sandblasting angle, and utilizes the nozzle 11, the side baffle 2 and the rotatable adjustment mechanism to achieve efficient and wide-range sandblasting operations.

[0022] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
