Description

Technical Field

[0001] The utility model belongs to the technical field of shot blasting cleaning, and particularly relates to a shot blasting cleaning mechanism with a multi-layer sealing device at the top. Background Art

[0002] A shot blasting cleaning mechanism is a device used to clean dirt, oxides, and welding spatter on the surface of metals. By using a shot blasting machine that rotates at high speed to project particulate matters such as steel shots onto the surface of the workpiece, the cleaning effect is achieved through the impact force. This process can not only improve the cleanliness of the metal surface but also help enhance the surface roughness, thereby improving the adhesion of subsequent coatings or treatments. It is widely used in industries such as casting, forging, and mechanical manufacturing. During the shot blasting process of existing shot blasting cleaning mechanisms, a large amount of dust is generated, which fills the inside of the shot blasting chamber. If not controlled, it will pose a hazard to the health of operators and affect the workshop environment. The conventional countermeasure is to use a fan air extraction system to remove the dust in a timely manner. Although these methods can reduce the dust leakage to a certain extent, there are still drawbacks. During the process of removing dust by the fan air extraction system, there is still a small amount of dust leakage and it cannot completely prevent dust leakage. Therefore, a new structure is proposed to solve the above problems. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a shot blasting cleaning mechanism with a multi-layer sealing device at the top.

[0004] The utility model is realized through the following technical solutions: A shot blasting cleaning mechanism with a multi-layer sealing device at the top, comprising: a dust storage box, a first docking pipe, and an air extraction pipe. A sealing frame is provided on the outer side of the bottom of the dust storage box, a fixed pipe is provided on the top of the dust storage box, and a sealing ring is provided on the outer side of the bottom of the fixed pipe;

[0005] A second sealing layer is adhesively bonded to the outer side of the fixed pipe. The second sealing layer is a cylindrical structure with a gradually increasing radius from bottom to top. A docking groove is formed by the downward depression of the annular area far from the center of the circle at the top of the fixed pipe, and a first sealing layer is adhesively bonded to the side surface close to the center of the circle of the docking groove;

[0006] A rotary connecting pipe is movably sleeved on the outer side of the fixed pipe. An internal thread groove is provided on the inner side of the rotary connecting pipe. An air extraction pipe is provided above the fixed pipe. A docking pipe is provided at the bottom of the air extraction pipe. A third sealing layer is adhesively bonded to the outer side of the docking pipe. Threads matching the specifications of the internal thread groove are provided on the outer side surface of the air extraction pipe. A retaining ring is provided at the top of the threads, and a fourth sealing layer is adhesively bonded to the bottom of the retaining ring.

[0007] As a preferred embodiment, a cleaning mechanism main body is provided below the dust temporary storage box. The bottom of the dust temporary storage box is connected to the top of the cleaning mechanism main body in a penetrating manner. The inner side of the sealing frame is adhesively bonded to the lower side of the side of the dust temporary storage box, and the bottom of the sealing frame is adhesively bonded to the top of the cleaning mechanism main body.

[0008] As a preferred embodiment, the sealing frame, the sealing ring, the first sealing layer, the second sealing layer, the third sealing layer and the fourth sealing layer are all made of rubber. The side of the sealing ring is adhesively bonded to the side of the fixed pipe, and the bottom of the sealing ring is adhesively bonded to the top of the dust temporary storage box.

[0009] As a preferred embodiment, the top of the dust temporary storage box is connected to the bottom of the fixed pipe in a penetrating manner. The radius length of the fixed pipe matches the radius length of the air extraction pipe, and the inner circle radius length of the rotary connection pipe matches the outer circle radius length of the air extraction pipe, ensuring that the rotary connection pipe can be rotatably connected to the outside of the air extraction pipe.

[0010] As a preferred embodiment, the air extraction pipe and the docking pipe are of an integral structure. The radius length of the docking pipe matches the radius length of the docking groove, the wall thickness of the docking pipe matches the width of the docking groove, and the height of the docking pipe matches the depth of the docking groove, ensuring that the docking pipe can be completely inserted into the docking groove.

[0011] As a preferred embodiment, the inner circle radius length of the rotary connection pipe is greater than the radius length of the bottom of the second sealing layer, and the inner circle radius length of the rotary connection pipe is less than the radius length of the top of the second sealing layer, ensuring that when the rotary connection pipe rotates upward and moves, the bottom of the rotary connection pipe gradually squeezes the side of the second sealing layer upward, thereby sealing the bottom of the rotary connection pipe through the second sealing layer.

[0012] As a preferred embodiment, the height of the rotary connection pipe is equal to the height of the threaded part of the air extraction pipe. The rotary connection pipe, the air extraction pipe and the fixed pipe are all made of stainless steel. The radius length of the rotary connection pipe is less than the radius length of the retaining ring. During actual use, the docking pipe at the bottom of the air extraction pipe is inserted downward into the docking groove at the top of the fixed pipe, so that the third sealing layer on the outside of the docking pipe contacts the side of the docking groove away from the center of the circle, and the first sealing layer contacts the inner wall of the docking pipe, thereby achieving a double-sealing effect. Then, the rotary connection pipe outside the fixed pipe is rotated upward so that the internal thread groove inside the rotary connection pipe is rotatably connected to the thread on the outside of the air extraction pipe. At this time, the rotary connection pipe rotates upward and moves, and gradually covers the docking part between the bottom of the air extraction pipe and the top of the fixed pipe. Moreover, the bottom of the rotary connection pipe moves upward and gradually squeezes the second sealing layer outside the fixed pipe. When the fourth sealing layer adhesively bonded to the bottom of the retaining ring by the top of the rotary connection pipe is tightened, the rotary connection is completed at this time. The second sealing layer and the fourth sealing layer seal the gaps between the rotary connection pipe and the fixed pipe and the air extraction pipe, and the final effect is to greatly improve the sealing effect at the top of the cleaning mechanism main body.

[0013] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: By setting a sealing frame and a sealing ring, dust leakage at the bottom and top of the dust storage box can be prevented. By setting a fixed pipe, an exhaust pipe, a rotary pipe, a first sealing layer, a second sealing layer and a third sealing layer, the docking pipe at the bottom of the exhaust pipe is inserted into the docking groove, so that the side of the first sealing layer away from the center of the circle contacts the inner side of the docking pipe, and at the same time, the third sealing layer on the outer side of the docking pipe contacts the side of the docking groove away from the center of the circle, thereby achieving the effect of preventing dust leakage. Then, move the rotary pipe upward and rotate it, so that the internal thread groove on the inner side of the rotary pipe is rotationally connected with the thread on the outer side of the exhaust pipe, so that the rotary pipe moves upward along the outer sides of the fixed pipe and the exhaust pipe. At the same time, the inner side of the bottom of the rotary pipe is gradually pressed against the second sealing layer. When the top of the rotary pipe is pressed tightly against the fourth sealing layer at the bottom of the retaining ring, the rotary connection of the rotary pipe is completed. The second sealing layer and the fourth sealing layer seal the gap between the rotary pipe and the fixed pipe and the exhaust pipe to prevent dust leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] Please refer to Figures 1 to 5 : A shot blasting cleaning mechanism for a top multi - layer sealing device, including: a dust temporary storage box 100, a docking pipe 310 one, and an extraction air duct 300. A sealing frame 110 is provided on the outer side of the bottom of the dust temporary storage box 100, a fixed pipe 200 is provided on the top of the dust temporary storage box 100, and a sealing ring 120 is provided on the outer side of the bottom of the fixed pipe 200;

[0026] A seal layer two 212 is adhesively bonded to the outer side of the fixed pipe 200. The seal layer two 212 is a cylindrical structure with a gradually increasing radius from bottom to top. A docking groove 210 is formed by the downward depression of the annular area far from the center of the circle at the top of the fixed pipe 200, and a seal layer one 211 is adhesively bonded to the side close to the center of the circle of the docking groove 210;

[0027] A rotary connection pipe 400 is movably sleeved on the outer side of the fixed pipe 200. An internal thread groove is provided on the inner side of the rotary connection pipe 400. An extraction air duct 300 is provided above the fixed pipe 200. A docking pipe 310 is provided at the bottom of the extraction air duct 300. A seal layer three 311 is adhesively bonded to the outer side of the docking pipe 310. Threads matching the specifications of the internal thread groove are provided on the outer side of the extraction air duct 300. A retaining ring 320 is provided at the top of the threads, and a seal layer four 321 is adhesively bonded to the bottom of the retaining ring 320.

[0028] A cleaning mechanism main body is provided below the dust temporary storage box 100. The bottom of the dust temporary storage box 100 is connected to the top of the cleaning mechanism main body in a penetrating manner. The inner side of the sealing frame 110 is adhesively bonded to the lower side of the side of the dust temporary storage box 100, and the bottom of the sealing frame 110 is adhesively bonded to the top of the cleaning mechanism main body.

[0029] The sealing frame 110, the sealing ring 120, the seal layer one 211, the seal layer two 212, the seal layer three 311, and the seal layer four 321 are all made of rubber material. The side of the sealing ring 120 is adhesively bonded to the side of the fixed pipe 200, and the bottom of the sealing ring 120 is adhesively bonded to the top of the dust temporary storage box 100.

[0030] The top of the dust storage box 100 is connected through and communicated with the bottom of the fixed pipe 200. The radius length of the fixed pipe 200 matches the radius length of the exhaust pipe 300, and the inner circle radius length of the rotary connecting pipe 400 matches the outer circle radius length of the exhaust pipe 300, ensuring that the rotary connecting pipe 400 can be rotatably connected to the outside of the exhaust pipe 300.

[0031] The exhaust pipe 300 and the docking pipe 310 are of an integral structure. The radius length of the docking pipe 310 matches the radius length of the docking groove 210, the wall thickness of the docking pipe 310 matches the width of the docking groove 210, and the height of the docking pipe 310 matches the depth of the docking groove 210, ensuring that the docking pipe 310 can be completely inserted into the docking groove 210.

[0032] The inner circle radius length of the rotary connecting pipe 400 is greater than the radius length of the bottom of the second sealing layer 212 and less than the radius length of the top of the second sealing layer 212. When the rotary connecting pipe 400 rotates and moves upward, the bottom of the rotary connecting pipe 400 gradually squeezes the side of the second sealing layer 212 upward, thereby sealing the bottom of the rotary connecting pipe 400 through the second sealing layer 212.

[0033] The height of the rotary connecting pipe 400 is equal to the height of the threaded part of the exhaust pipe 300. The rotary connecting pipe 400, the exhaust pipe 300, and the fixed pipe 200 are all made of stainless steel. The radius length of the rotary connecting pipe 400 is less than the radius length of the retaining ring 320. The retaining ring 320 prevents the rotary connecting pipe 400 from rotating excessively, and the fourth sealing layer 321 below the baffle can seal the gap at the junction of the rotary connecting pipe 400 and the retaining ring 320.

[0034] Example 1: Please refer to Figures 1 to 5, during actual use, the sealing frame 110 at the bottom of the dust storage box 100 can seal the bottom of the dust storage box 100, and the sealing ring 120 at the top of the dust storage box 100 can seal the welding part at the bottom of the fixed pipe 200. The docking pipe 310 at the bottom of the exhaust pipe 300 is inserted downward into the docking groove 210 at the top of the fixed pipe 200, so that the sealing layer three 311 on the outer side of the docking pipe 310 contacts the side of the docking groove 210 away from the center of the circle, and the sealing layer one 211 contacts the inner wall of the docking pipe 310, thus achieving a double-sealing effect. Then, the rotary pipe 400 on the outer side of the fixed pipe 200 is rotated upward, so that the internal thread groove on the inner side of the rotary pipe 400 is rotationally connected with the external thread on the outer side of the exhaust pipe 300. At this time, the rotary pipe 400 rotates upward and moves, and gradually covers the docking part between the bottom of the exhaust pipe 300 and the top of the fixed pipe 200. Moreover, the bottom of the rotary pipe moves upward and gradually presses the sealing layer two 212 on the outer side of the fixed pipe 200. When the sealing layer four 321 glued to the bottom of the retaining ring 320 by the top of the rotary pipe is pressed tightly, the rotary pipe is then screwed together. The sealing layer two 212 and the sealing layer four 321 seal the gap between the rotary pipe 400, the fixed pipe 200 and the exhaust pipe 300. The final effect is to greatly improve the sealing effect at the top of the main body of the cleaning mechanism.

[0035] Embodiment 2: Please refer to Figures 2 to 5 , when the main body of the cleaning mechanism is not working, the rotary pipe 400 can be rotated reversely, so that the internal thread groove on the inner side of the rotary pipe 400 is rotationally disengaged from the external thread on the outer side of the exhaust pipe 300. The rotary pipe 400 is moved downward along the outer side of the fixed pipe 200 to the lower side of the side of the fixed pipe 200, and then the exhaust pipe 300 is lifted upward, so that the docking pipe 310 at the bottom of the exhaust pipe 300 is disengaged upward from the inside of the docking groove 210, so that the exhaust pipe 300 and the fixed pipe 200 can be separated. The final effect is to facilitate the cleaning and maintenance of the interiors of the fixed pipe 200, the rotary pipe 400 and the exhaust pipe 300, and to extend the service lives of the fixed pipe 200, the rotary pipe 400 and the exhaust pipe 300.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
