Description

Technical Field

[0001] The invention relates to the technical field of smoke and dust cleaning, in particular to a workshop smoke and dust cleaning device. Background Art

[0002] In order to reduce the impact of various harmful gases and smoke generated in the production process on the health of production personnel, the design of workshops and production lines must be equipped with smoke and dust removal devices. There are some studies on smoke and dust cleaning devices for workshops and production lines in the existing technology.

[0003] For example, the Chinese utility model patent with publication number CN211304164U discloses an environmentally friendly smoke cleaning device, including a welding smoke treatment device, a functional seat, the left and right sides of the top surface of the welding smoke treatment device are respectively connected with a first and a second corrugated pipe type smoking pipe through a first connecting seat and a second connecting seat, and the first smoking pipe and the second smoking pipe are respectively bent toward the two sides; the functional seat is two places, and two frame-type moving wheels are respectively installed on their bottom surfaces, and separated by a row of transparent rubber strip-style baffles. For another example, the Chinese utility model with publication number CN217315029U discloses a foldable dust removal and smoking hood for a forging workshop, including a cantilever crane, a smoking hood assembly and a smoke exhaust pipe, the cantilever of the cantilever crane is connected to a traveling crane, the smoking hood assembly includes a top plate, a group of side plates and a driving mechanism, a group of side plates are rotatably arranged on the opposite sides of the top plate through a hinge seat, the top of the top plate is fixed with a mounting plate through a number of connecting rods, the mounting plate is fixed on the traveling crane, and a group of smoke exhaust ports are arranged on the top plate.

[0004] During actual use, the smoke hood is often used in conjunction with a bellows. Specifically, the bellows is connected to the top of the smoke hood, so that even if the smoke hood is translated within a certain range, the smoke absorbed inside can be discharged through the bellows. The bellows also bends and expands synchronously when the smoke hood is translated. When the bellows bends and elongates, the smoke absorbed by the smoke hood will collide with the inner wall of the bellows during the upward movement, and some of the smoke will remain in the annular gap of the smoke hood. After the bellows resumes contraction, it will squeeze out the remaining smoke. If these squeezed smoke are not cleaned in time, they will combine with water vapor in the air to form small particles. The small particles will fall onto the workpiece under the smoke hood under the action of gravity, affecting the surface finish of the workpiece. Therefore, how to clean the smoke remaining on the inner wall of the bellows in a timely and effective manner is a problem that technicians in this field need to solve. Summary of the invention

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, this embodiment provides a workshop smoke cleaning device, including a smoke hood 1 and a bellows 2 located inside a workshop processing room, an adsorption mechanism is arranged in the bellows 2, and the adsorption mechanism can adopt activated carbon adsorption or filter paper adsorption, the smoke hood 1 is horizontally slidably installed on the side wall of the workshop processing room (a driving member for driving the smoke hood 1 to translate is arranged in the workshop processing room, which is not shown in the figure), a rectangular opening is formed at the bottom of the smoke hood 1, and the opening is located above the processed part during the processing, the bellows 2 is installed on the top of the workshop processing room and connected to the external ventilation duct, and the bottom end of the bellows 2 is detachably connected to the top of the smoke hood 1; the ventilation duct is connected to the air pump, so that negative pressure is generated in the smoke hood 1 and the bellows 2 when working, so that the external air is sucked into the smoke hood 1 and the bellows 2; specifically, the device in the workshop processing room performs punching and hemming operations on the plate, and the smoke generated in the process enters the smoke hood 1 through the opening of the smoke hood 1 and is discharged through the bellows 2.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, a horizontal guide rail 3 is fixedly installed in the smoke hood 1 through a bracket. The guide rail 3 is annular and coaxial with the corrugated pipe 2 in a vertical state; an annular plate 4 coaxial with the corrugated pipe 2 is rotatably installed on the guide rail 3, and multiple guide rods 5 are vertically fixedly installed on the annular plate 4. A lifting platform 6 is slidably installed on the multiple guide rods 5. The cross section of the lifting platform 6 is circular and a cavity is formed inside. A plurality of rigid tubes 7 connected to the internal cavity are installed on the side wall of the lifting platform 6. The top of the rigid tube 7 is closed, and a vertical strip groove 701 is opened on the rigid tube 7; a circular tube 8 connected to the internal cavity is installed on the top of the lifting platform 6; the rigid tube 7 includes a vertical section, a horizontal section, and a curved section connecting the vertical section and the horizontal section. When the lifting platform 6 rises along the guide rod 5 under the action of an external force, it drives the rigid tube 7 and the circular tube 8 to rise synchronously.

[0028] like Figure 4 As shown, a horizontal circular plate 9 is fixedly installed on the circular tube 8, and the diameter of the circular plate 9 is 1 mm smaller than the internal diameter of the corrugated tube 2 in the vertical contraction state; the rigid tube 7 passes through the circular plate 9 and the outer wall of the rigid tube 7 is in contact with the circular plate 9; a through groove 901 cooperating with the guide rod 5 is opened on the circular plate 9.

[0029] Specifically, in the initial state, the bellows 2 is in a vertical state, that is, the bellows 2 is in a contracted state; when processing the plate, the smoke cover 1 is translated to the position of the plate, and the bellows 2 is in a bent and stretched state. Before the bellows 2 changes from a vertical state to a bent state, the lifting platform 6, the rigid tube 7, the round tube 8 and the round plate 9 are moved from the vertical state to the curved state. Figure 1 The state changes to Figure 3 state, that is, the lifting platform 6, the rigid tube 7, the round tube 8 and the round plate 9 move downward into the smoke hood 1 as a whole, so that the bellows 2 will not interfere with the lifting platform 6, the rigid tube 7, the round tube 8 and the round plate 9 during the bending process; during the processing, the smoke and dust generated by the plate enters the bellows 2 through the smoke and dust hood 1 and is discharged through the ventilation duct; after the processing is completed, the smoke and dust hood 1 moves horizontally to the initial state, and the lifting platform 6, the rigid tube 7, the round tube 8 and the round plate 9 rise to the Figure 1 State; in this state, the external air pump is still working, so that negative pressure is generated in the bellows 2. Since the circular plate 9 separates the bellows 2 at this time, and the diameter of the circular plate 9 is 1 mm smaller than the diameter of the bellows 2, the external air will enter the bellows 2 through the gap between the circular plate 9 and the bellows 2 after entering the smoke and dust hood 1, and part of the air will enter the rigid tube 7 through the strip groove 701, and then pass through the lifting platform 6 and the circular tube 8, and then enter the bellows 2 from the top of the circular tube 8, and finally be discharged from the ventilation duct; in the above process, the flow direction of the air when entering the rigid tube 7 through the strip groove 701 tends to be horizontal, thereby driving part of the smoke and dust remaining on the inner wall of the rigid tube 7 to enter the rigid tube 7 synchronously, and driving the smoke and dust to pass through the lifting platform 6 and the circular tube 8, and finally enter the bellows 2 and be discharged from the ventilation duct.

[0030] It should be noted that the air in the smoke hood 1 enters the bellows 2 through the gap between the circular plate 9 and the bellows 2 and then flows upward along the inner wall of the bellows 2. In this process, the air collides with the uneven inner wall of the bellows 2, generating turbulence, which promotes the separation of the smoke and dust remaining on the inner wall of the bellows 2 from the bellows 2, thereby making it more conducive for the lateral airflow to drive the smoke and dust into the rigid tube 7.

[0031] In this embodiment, there are two design schemes for the position of the circular plate 9. One is as follows: Figure 4 As shown, the circular plate 9 is installed at the position corresponding to the bottom end of the strip groove 701. In this case, the vertical airflow corresponding to the position of the rigid tube 7 is stronger, while the horizontal airflow is weaker. Another method is to install the circular plate 9 at the position corresponding to the top end of the strip groove 701. In this case, the horizontal airflow corresponding to the position of the rigid tube 7 is stronger, while the vertical airflow is weaker. After testing, the cleaning effects of the two methods are not much different.

[0032] like Figure 1 , Figure 2 and Figure 4As shown, a horizontal lifting ring 10 is movably installed on the lifting platform 6, a winding wheel 11 and a first motor 12 for driving the winding wheel 11 are installed on the smoke hood 1, a pull wire 13 is wound on the winding wheel 11, and one end of the pull wire 13 is fixedly connected to the lifting ring 10. Specifically, a semicircular ring is installed on the side wall of the lifting ring 10, and one end of the pull wire 13 is wound on the semicircular ring; a plurality of balls that roll with the lifting platform 6 are evenly installed on the lifting ring 10 along its circumference to reduce the friction between the lifting ring 10 and the lifting platform 6. It should be noted that the number of the winding wheel 11, the first motor 12 and the pull wire 13 are all two, and the pull wire 13 is symmetrically distributed on both sides of the lifting ring 10.

[0033] exist Figure 1 In the state, the winding wheel 11 is in the reeling state, and the pulling wire 13 is wound on the winding wheel 11; when the first motor 12 is started and drives the winding wheel 11 to rotate forward, the winding wheel 11 gradually unwinds, that is, the pulling wire 13 tends to relax, and at this time, the lifting platform 6, the rigid tube 7, the round tube 8, the round plate 9 and the lifting ring 10 move downward as a whole under the action of gravity, and pull the pulling wire 13 so that the pulling wire 13 is in a tensioned state; until the lifting platform 6, the rigid tube 7, the round tube 8, the round plate 9 and the lifting ring 10 are lowered to Figure 3 Similarly, when the first motor 12 is started and the winding wheel 11 is driven to reverse, the winding wheel 11 gradually reels the wire 13, and the lifting platform 6, the rigid tube 7, the round tube 8, the round plate 9 and the lifting ring 10 as a whole rise to the position under the pulling force of the wire 13. Figure 1 Status shown.

[0034] like Figure 6 As shown, a bevel gear ring 14 is fixedly mounted on the annular plate 4, a gear shaft 15 meshing with the bevel gear ring 14 and a second motor 16 for driving the gear shaft 15 are mounted on the guide rail 3; during the cleaning process of the inner wall of the bellows 2, the second motor 16 drives the wheel shaft 15 to rotate, and the wheel shaft 15 drives the bevel gear ring 14 and the annular plate 4 to rotate, so that the guide rod 5, the lifting platform 6, the rigid tube 7, the circular tube 8, the circular plate 9 and the lifting ring 10 rotate as a whole, so that the rigid tube 7 can clean the smoke and dust remaining at various positions on the inner wall of the bellows 2.

[0035] During the research and development process, it was found that if the position of the rigid tube 7 is designed to fit the inner wall of the corrugated tube 2 in the vertical state, the rigid tube 7 will be scratched against the inner wall of the corrugated tube 2 when it rises, and even affect the normal rise of the rigid tube 7; if the position of the rigid tube 7 is designed to be separated from the inner wall of the corrugated tube 2 in the vertical state, due to the existence of the gap, the rigid tube 7 has a poor cleaning effect on the smoke and dust remaining on the inner wall of the corrugated tube 2. Based on this, the following design is also made in this embodiment.

[0036] like Figure 7As shown, the horizontal section of the rigid tube 7 slides with the lifting platform 6 along the radial direction of the lifting platform 6, and an elastic member 17 is connected between the rigid tube 7 and the lifting platform 6; during the rising process of the rigid tube 7, it does not contact the inner wall of the corrugated tube 2. When the rigid tube 7 rises to Figure 1 After reaching a predetermined height, the rigid tube 7 overcomes the force of the elastic member 17 under the action of external force and moves horizontally, the elastic member 17 is stretched, and the rigid tube 7 fits against the inner wall of the corrugated tube 2, thereby improving the cleaning effect of the residual smoke and dust on the inner wall of the corrugated tube 2.

[0037] like Figure 5 and Figure 7 As shown, a circular shaft 18 coaxial with the lifting platform 6 is movably installed on the lifting platform 6, a mounting sleeve 19 located in the lifting platform 6 is rotatably installed on the circular shaft 18, and a blade wheel 20 located in the circular tube 8 is fixedly installed on the circular shaft 18; an adjustment plate 21 located in the lifting platform 6 is fixedly installed on the end of the horizontal section of the rigid tube 7, and an inclined groove 22 is opened on the adjustment plate 21; a support arm 23 is fixedly installed on the mounting sleeve 19 at a position corresponding to each adjustment plate 21, and a round pin 24 cooperating with the corresponding inclined groove 22 is rotatably installed on the support arm 23.

[0038] Specifically, when air enters the lifting platform 6 and the circular tube 8 from the rigid tube 7 and finally flows out from the top of the circular tube 8, the airflow will drive the impeller 20 to rotate, thereby driving the circular shaft 18 to rotate. In this process, the impeller 20 and the circular shaft 18 are displaced upward under the action of the airflow, and drive the mounting sleeve 19, the support arm 23 and the circular pin 24 to rise. During the rising process of the circular pin 24, the interaction force with the inclined groove 22 causes the adjustment plate 21 and the rigid tube 7 to produce horizontal displacement until the circular pin 24 moves to the top of the inclined groove 22, and the rigid tube 7 is also separated from the inner wall of the corrugated tube 2; after the inner wall of the corrugated tube 2 is cleaned, the external air pump stops working, and the air in the rigid tube 7, the lifting platform 6 and the circular tube 8 also stops flowing. The impeller 20 and the circular shaft 18 stop rotating and descend to the initial height under the action of gravity. The resilience of the elastic member 17 causes the adjustment plate 21 and the rigid tube 7 to produce reverse horizontal displacement and return to the initial position, and the rigid tube 7 is separated from the inner wall of the corrugated tube 2. To sum up, in this embodiment, when the rigid tube 7 is rising, the external air pump does not work, and the rigid tube 7 remains separated from the inner wall of the corrugated tube 2; when the rigid tube 7 rises to a predetermined height, the external air pump works, and the rigid tube 7 automatically fits against the inner wall of the corrugated tube 2, thereby improving the cleaning effect of the residual smoke and dust on the inner wall of the corrugated tube 2.

[0039] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
