Description

Technical Field

[0001] This invention relates to the field of dust removal technology, and in particular to a dust removal mechanism for the production of powdered film release agents. Background Technology

[0002] The production of powdered film release agents involves the crushing and processing of raw materials. During the crushing process, a large amount of dust is easily generated above the crushing drum. This dust has a small particle size and is easy to disperse. If the dispersed dust is inhaled by the operators, it will affect their health. Therefore, if this dust is not treated, it can easily cause air pollution.

[0003] Currently, the method for dust removal from crushing processes involves using dust collection equipment. This equipment mainly includes a dust collection hood, a transmission pipeline, a spray box, and a negative pressure pipe. The dust collection hood is connected to the spray box via the transmission pipeline. A negative pressure pipe is installed on one side of the spray box, and a negative pressure fan is installed inside the negative pressure pipe. When the negative pressure fan is activated, the dust collection hood generates suction to the space below, causing the dust to enter the dust collection pipe, then be transported through the transmission pipeline into the spray box, and finally discharged through the negative pressure pipe. The spray box separates the dust from the airflow, allowing the crystallized air to be discharged through the negative pressure pipe. However, the above-mentioned dust collection equipment has shortcomings in use: due to the limitations of the objective conditions in the production workshop, the transmission pipeline is often quite long and has bends. To reduce airflow attenuation, the transmission pipeline usually contains a bend. However, due to the large amount of dust and the long length of the transmission pipeline, a large amount of dust easily accumulates on the inner wall of the pipeline. Once this dust accumulation reaches a certain level, it will seriously affect the ventilation volume, thus greatly reducing the dust removal effect.

[0004] Therefore, this invention proposes a dust removal mechanism for the production of powdered film release agent. Summary of the Invention

[0005] The purpose of this invention is to provide a dust removal mechanism for the production of powdered film release agent in order to solve the problems mentioned in the background art.

Several circumferentially evenly distributed scrapers, one side of which is attached to the inner wall of the cylinder, are installed inside the cylinder. One end of each scraper is fixedly connected to the outer wall of the annular plate at one end of the cylinder. The mechanism also includes a control component for controlling the axial movement of the cleaning mechanism inside the vertical and horizontal pipes.

[0007] As a further description of the above technical solution: The control assembly includes an upper spring, a lower spring, an upper rope, and a lower rope. A coaxial baffle is fixedly connected to the inner circumferential wall of the cylinder via a support plate. A traction shaft is fixedly connected to one side of the baffle. An upper spring is placed inside the horizontal tube, located between the baffle and one end of the horizontal tube. The upper rope is movably installed through one end of the horizontal tube, and one end of the upper rope is fixedly connected to one end of the traction shaft inside the horizontal tube. A baffle is fixedly connected to the inner circumferential wall of the vertical tube, near the horizontal tube. The lower spring is located inside the vertical tube, between the baffle and the baffle. The lower rope is movably installed through the vertical tube, near the outer wall of the horizontal tube, and one end of it is fixedly connected to the top end of the traction shaft inside the vertical tube.

[0008] As a further description of the above technical solution: The control assembly includes a traction seat, which is disposed above the horizontal tube and the two slide together along the axial direction of the horizontal tube. A left reversing wheel is disposed on the top of the horizontal tube near the other end. A right reversing wheel 1, a right reversing wheel 2, a right reversing wheel 3 and a right reversing wheel 4 are disposed sequentially from top to bottom on the outside of one end of the horizontal tube. A lower reversing wheel is disposed on the top wall of the baffle. The other ends of the upper rope and the lower rope are fixedly connected to the two sides of the traction seat, respectively.

[0009] As a further description of the above technical solution: Two guide shafts are fixedly connected to one side of the seat plate on the right reversing wheel four, respectively located on both sides of the vertical tube. Guide sleeves are fixedly connected to both sides of the vertical tube and sleeved outside the guide shafts. The guide sleeves and guide shafts are slidably engaged. A connecting plate is fixedly connected between the two guide shafts. A lower drive shaft is screwed through the connecting plate. A base that is rotatably connected to the lower drive shaft is fixedly connected to the bottom wall of the horizontal tube.

[0010] As a further description of the above technical solution: The top wall of the horizontal tube is fixedly connected to two support plates, which are located near both ends. A guide post and an upper drive shaft are provided between the two support plates. The guide post and the support plates are fixedly connected and slidably connected to the traction seat. The two ends of the upper drive shaft are rotatably connected to the two support plates and are screwed through to the traction seat.

[0011] As a further description of the above technical solution: The roller assembly includes a support plate and two grooved wheels disposed on one side of the support plate.

[0012] As a further description of the above technical solution: A coaxial mating sleeve is fixedly connected inside the ring plate. The mating sleeve is fitted onto the outside of the cylinder. An annular groove is formed on the outer peripheral wall of the cylinder, located inside the mating sleeve. A rotating roller is arranged in the annular groove. A rolling groove adapted to the rotating roller is formed on the inner peripheral wall of the mating sleeve.

[0013] As a further description of the above technical solution: The end of the cylinder is fitted with a sealing ring located inside the mating sleeve.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, a movable cleaning mechanism is provided inside the vertical and horizontal pipes. The cleaning mechanism includes a cylinder and an annular plate. When the cylinder moves, the annular plate moves as well. When the annular plate moves, it uses the cleaning strips on its outer periphery to clean the dust attached to the pipe wall. A scraper is provided inside the cylinder. The scraper is fixedly connected to one of the annular plates. By setting a spiral guide strip and a guide block, the annular plate drives the scraper to revolve when the cylinder moves. When the scraper revolve, it can scrape the inner wall of the cylinder. Thus, the cleaning mechanism in this invention can not only clean the dust on the inner wall of the vertical and horizontal pipes, but also has the function of self-cleaning dust, which greatly extends the service life of the cleaning mechanism.

[0015] 2. In this invention, the control components include an upper spring, a lower spring, an upper rope, a lower rope, a traction seat, a left reversing wheel, a right reversing wheel one, a right reversing wheel two, a right reversing wheel three, a right reversing wheel four, and a lower reversing wheel. By controlling the left and right sliding of the traction seat, the cleaning mechanism inside the vertical and horizontal pipes can be moved, which has the advantage of making it more convenient to clean the dust adhering to the inner wall of the vertical and horizontal pipes.

[0016] 3. In this invention, by setting up a right reversing wheel, a seat plate, a guide shaft, a lower transmission shaft, and a guide sleeve, it is convenient to control the cleaning mechanism in the vertical and horizontal tubes to produce different strokes. That is to say, under the constraints of objective conditions in the production workshop, the lengths of the vertical and horizontal tubes may be different. The above-mentioned setting of different stroke movement functions enables this mechanism to be applicable to various production conditions. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-12 A dust removal mechanism for the production of powdered film release agent includes a vertical pipe 1 and a horizontal pipe 2. A lower connecting flange 11 is welded to the bottom of the vertical pipe 1, and the vertical pipe 1 is fixedly installed on the top of a spray box 130 through the lower connecting flange 11. An exhaust pipe 140 is fixedly installed on one side of the spray box 130, and the exhaust pipe 140 applies negative pressure to the spray box 130. The bottom of the horizontal pipe 2 and one end of the horizontal pipe 2 are fixedly connected to the top of the vertical pipe 1. The horizontal pipe 2 and the vertical pipe 1 are perpendicular and connected to each other. The horizontal pipe 2 and the vertical pipe 1 form a long dust transmission channel. Dust easily adheres to and accumulates on the inner wall of this long dust transmission channel. When the amount of accumulated dust is too large, it will not only reduce the air volume, but also easily increase the safety hazard. The bottom of the horizontal pipe 2 is welded to a dust collection connection pipe 21 near the other end. The bottom end of the dust collection connection pipe 21 is fixedly connected to a flange, through which a dust collection hood for collecting and guiding dust can be connected. The specifications of this dust collection hood are determined according to actual requirements. After the dust collection hood is used, it can eliminate air pollution. The spray box 130 mentioned above uses a gas-liquid contact method to trap dust in the airflow in the water, so that the exhaust pipe 140 discharges clean air. In specific use, a high-efficiency activated carbon filter can also be installed at the air outlet of the exhaust pipe 140 to further adsorb dust residue.

[0021] In this technical solution, a cleaning mechanism 3 is provided in both the vertical pipe 1 and the horizontal pipe 2. This cleaning mechanism 3 is used to clean the dust adhering to the inner wall of the vertical pipe 1 and the horizontal pipe 2. Specifically, the cleaning mechanism 3 moves to clean the dust, and at the same time, the cleaning mechanism 3 has its own function of preventing dust accumulation.

[0022] Specifically, the cleaning mechanism 3 includes a cylinder 31 and an annular plate 32. Annular plates 32 are fitted around both ends of the cylinder 31. The annular plates 32 and the cylinder 31 are rotatably connected, and their outer peripheral walls are fixedly provided with evenly distributed cleaning bristles 321. Specifically, a coaxial mating sleeve 323 is fixedly connected inside the annular plate 32. The mating sleeve 323 is fitted around the outside of the cylinder 31. An annular groove 314 is formed on the outer peripheral wall of the cylinder 31, located within the mating sleeve 323. An inner rotating roller 120 is provided, and the inner peripheral wall of the mating sleeve 323 is provided with a groove 3231 that matches the rotating roller 120. The rotating roller 120 makes the rotation of the ring plate 32 relative to the cylinder 31 smoother. The end of the cylinder 31 is fitted with a sealing ring 110 located inside the mating sleeve 323. The function of the sealing ring 110 is to prevent dust from entering the cavity where the rotating roller 120 is located, and it can also effectively block dust from entering the gap between the mating sleeve 323 and the cylinder 31. The cleaning bristles 321 abut against the inner circumferential wall of the corresponding pipe. The outer circumferential wall of the cylinder 31 is provided with at least three circumferentially evenly distributed roller assemblies 311. The inner circumferential walls of the vertical pipe 1 and the horizontal pipe 2 are fixedly connected with guide rails 4 that are adapted to the roller assemblies 311. Under the guidance of the roller assemblies 311 and the guide rails 4, the cylinder 31 can move along the axial direction of the corresponding pipe without jamming. At the same time, the cylinder 31 and the corresponding pipe are in a coaxial or nearly coaxial state. The inner cavity of the cylinder 31 is an air passage. Thus, when the cylinder 31 moves in the corresponding pipe, the cleaning bristles 321 can scrape the inner wall of the pipe and remove the dust attached to the inner wall of the pipe. The scraped dust will enter the spray box 130 with the airflow. After the spray pipe in the spray box 130 sprays water, the dust in the airflow is separated.

[0023] Furthermore, a guide block 322 is fixedly connected to the outer periphery of the ring plate 32, and a spiral guide strip 5 that slides and adapts to the guide block 322 is fixedly connected to the inner periphery of the vertical tube 1 and the horizontal tube 2. There are three spiral guide strips 5 in both the vertical tube 1 and the horizontal tube 2, and they are evenly distributed circumferentially. In specific implementation, a spiral guide strip 5 is set between adjacent guide rails 4. The aforementioned ring plate 32 can rotate relative to the cylinder 31. Thus, when the cylinder 31 moves, the guide block 322 is guided by the spiral guide strip 5, and the ring plate 32 will rotate relative to the cylinder 31 at a certain angle. Several scrapers 6 are evenly distributed circumferentially and one side is attached to the inner wall of the cylinder 31. One end of the scraper 6 is fixedly connected to the outer side wall of the ring plate 32 at one end of the cylinder 31. When the ring plate 32 rotates, it will drive the scraper 6 to revolve. The scraper 6 scrapes the inner wall of the cylinder 31 and can clean the dust attached to the inner wall of the cylinder 31.

[0024] In this embodiment, the roller assembly 311 includes a support plate 3111 and two grooved wheels 3112 disposed on one side of the support plate 3111. The guide rail 4 has a triangular cross-section, and one edge of the guide rail 4 passes through the inner groove of the grooved wheel 3112. The spiral guide bar 5 has a U-shaped cross-section, and a U-shaped groove 3221 is provided on one side of the guide block 322. The U-shaped groove 3221 rides on the outside of the spiral guide bar 5.

[0025] It also includes a control component 7 for controlling the axial movement of the cleaning mechanism 3 inside the vertical pipe 1 and the horizontal pipe 2. The function of the control component 7 is to drive the cleaning mechanism 3 inside the vertical pipe 1 and the horizontal pipe 2 to move axially.

[0026] Specifically, the control component 7 includes an upper spring 71, a lower spring 72, an upper rope 73, and a lower rope 74. The inner circumferential wall of the cylinder 31 is fixedly connected to a coaxial baffle 312 via a support plate. A traction shaft 3121 is fixedly connected to one side of the baffle 312. The horizontal tube 2 contains an upper spring 71 located between the baffle 312 and one end of the horizontal tube 2. The upper rope 73 is movably installed through one end of the horizontal tube 2. Specifically, a sleeve is fixedly installed in the middle of one end of the horizontal tube 2, and a polyurethane sleeve is fixedly installed inside the sleeve. The upper rope 73 passes through the polyurethane sleeve. One end of the upper rope 73 is fixedly connected to one end of the traction shaft 3121 inside the horizontal tube 2. The upper rope 73 is a steel wire rope. When the upper rope 73 is released, under the elastic thrust of the upper spring 71, the cleaning mechanism 3 inside the horizontal tube 2 will be at the other end, where the upper rope 73 passes through the upper spring 71. A baffle 8 is fixedly connected to the inner circumferential wall of the vertical tube 1 near the horizontal tube 2. The lower spring 72 is located inside the vertical tube 1 and between the baffle 312 and the baffle 8. The lower rope 74 is movably connected through the vertical tube 1 and is set near the outer wall of the horizontal tube 2, with one end fixedly connected to the top of the traction shaft 3121 inside the vertical tube 1. Specifically, a limiting tube is fixedly connected to the outer circumferential wall of the vertical tube 1, and a polyurethane sleeve is also fixedly fitted inside the limiting tube. The lower rope 74 passes through the polyurethane sleeve. After the lower rope 74 is released, the lower spring 72 will use its elasticity to push the entire cleaning mechanism 3 inside the vertical tube 1 to the bottom. In summary, by pulling and releasing the aforementioned lower rope 74 and upper rope 73, the cleaning mechanism 3 inside the vertical tube 1 and the horizontal tube 2 can be moved.

[0027] Furthermore, the control component 7 includes a traction seat 75, which is disposed above the horizontal tube 2 and the two slide in cooperation along the axial direction of the horizontal tube 2. Specifically, the top wall of the horizontal tube 2 is fixedly connected to two support plates 24 located near both ends. A guide post 108 and an upper drive shaft 109 are disposed between the two support plates 24. The guide post 108 is fixedly connected to the support plates 24 and slidably connected to the traction seat 75. Specifically, one end of the traction seat 75 is fixedly connected to a guide sleeve sleeved outside the guide post 108. The guide sleeve and the guide post 108 slide in cooperation. The upper drive shaft... The two ends of 109 are rotatably connected to the two support plates 24 and are screwed through to the traction seat 75. Specifically, the other end of the traction seat 75 is fixedly connected to a drive sleeve sleeved on the outside of the upper drive shaft 109. The drive sleeve has an internal thread, and the upper drive shaft 109 has an external thread. When the upper drive shaft 109 rotates, it can drive the traction seat 75 to move. A servo motor is fixedly installed on the outside of one of the support plates 24. The output shaft of the upper servo motor is fixedly connected to one end of the upper drive shaft 109. The upper servo motor provides driving force for the rotation of the upper drive shaft 109. A left reversing wheel 104 is provided at the top of the horizontal tube 2 near the other end. From top to bottom, right reversing wheel 1 9, right reversing wheel 2 101, right reversing wheel 3 102 and right reversing wheel 4 103 are arranged on the outside of one end of the horizontal tube 2. A lower reversing wheel 105 is provided on the top wall of the baffle 8. The lower rope 74 passes over the lower reversing wheel 105. The other ends of the upper rope 73 and the lower rope 74 are fixedly connected to the two sides of the traction seat 75, respectively. In use, the upper rope 73 extends from one end of the horizontal tube 2 and passes over right reversing wheel 3 102 and right reversing wheel 1 9 in sequence before being fixedly connected to the traction seat 75. The lower rope 74 extends from the outer wall of the vertical tube 1 and passes over right reversing wheel 4 103, right reversing wheel 2 101 and left reversing wheel 104 in sequence before being fixedly connected to the traction seat 75. When the traction seat 75 moves, it will pull the upper rope 73 and the lower rope 74, which will drive the cleaning mechanism 3 to move.

[0028] In this embodiment, the seat plate 1031 and the horizontal tube 2 on the right reversing wheel 4 103 are not fixedly connected. Two guide shafts 10311 are fixedly connected to one side of the seat plate 1031, respectively located on both sides of the vertical tube 1. Guide sleeves 12 are fixedly connected to both sides of the vertical tube 1, sleeved on the outside of the guide shafts 10311. The guide sleeves 12 and the guide shafts 10311 are slidably engaged. A connecting plate 106 is fixedly connected between the two guide shafts 10311. A lower drive shaft 107 is screwed through and screwed onto the connecting plate 106. In specific implementation, the outer wall of the lower drive shaft 107 is provided with external threads for connection. A transmission thread sleeve is fixedly connected to the middle of plate 106 and sleeved on the outside of the external thread. A base 22 that is rotatably connected to the bottom wall of horizontal tube 2 is fixedly connected to the base 22. In use, a lower servo motor is fixedly installed on the back of the base 22. The output shaft of the lower servo motor is fixedly connected to one end of the lower transmission shaft 107, thereby controlling the rotation of the lower transmission shaft 107. When the lower transmission shaft 107 rotates, it can indirectly control the movement of the right reversing wheel 4 103. This arrangement can adjust the travel of the cleaning mechanism 3 in the vertical tube 1, which is suitable for situations where the lengths of the vertical tube 1 and the horizontal tube 2 are different.

[0029] Working principle: Before use, use a blind flange to seal the left connecting flange 23 at one end of the horizontal pipe 2. Under the premise that the length of the vertical pipe 1 is greater than that of the horizontal pipe 2, when it is necessary to clean the inner walls of the vertical pipe 1 and the horizontal pipe 2, control the upper drive shaft 109 to rotate and drive the traction seat 75 to move to the right. At this time, the upper rope 73 is released, and the cylinder 31 moves inside the horizontal pipe 2 under the push of the upper spring 71. The ring plate 32 rotates, and the cleaning strip 321 cleans the dust attached to the inner wall of the horizontal pipe 2. At the same time, the lower rope 74 is pulled, and the cylinder 31 inside the vertical pipe 1 is lifted. The ring plate 32 connected to the cylinder 31 rotates. The rotation of the ring plate 32 mentioned above can not only drive the cleaning strip 321 to clean the corresponding pipe wall, but also drive the scraper 6 to scrape off the dust attached to the inner wall of the cylinder 31. When the travel of the cylinder 31 inside the vertical tube 1 is insufficient to cover the entire vertical tube 1, the lower drive shaft 107 is rotated. At this time, the right reversing wheel 103 will move outward and support the lower rope 74, so that the cylinder 31 inside the vertical tube 1 can continue to rise. Thus, by controlling the traction seat 75 to move back and forth, and then sequentially controlling the forward and reverse rotation of the lower drive shaft 107, the dust adhering to the inner wall of the vertical tube 1 and the horizontal tube 2 can be cleaned.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
