Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to a waste gas treatment device for stretch film production equipment. Background Art

[0002] Stretch film, also known as stretch film and heat shrink film, was first produced in China with PVC as the base material and DOA as the plasticizer and self-adhesive PVC stretch film. Stretch film is generally produced and processed by a film blowing machine, which heats and melts plastic particles and then blows them into a film. It is mainly composed of an extruder, a die head, a cooling device, a bubble stabilizing frame, a herringbone plate, a traction roller, a winding device, etc. When producing stretch film, the film blowing machine will generate waste gas, which contains dust particles, non-methane total hydrocarbons, styrene, etc. If the waste gas is not treated, it will be directly discharged into the air and pollute the air.

[0003] Nowadays, the waste gas generated by the stretch film production equipment needs to be treated by a filtering structure before it can be discharged. The waste gas contains a large amount of dust particles. When passing through the adsorption filter, the particles will remain on the surface of the filter. After filtering the waste gas for a long time, the surface of the filter will be blocked by impurities, affecting the waste gas treatment efficiency. Therefore, the filter structure needs to be cleaned or replaced regularly. In the waste gas treatment process of the stretch film production equipment, since the waste gas generated by the production contains a large amount of impurities such as particulate matter, the cleaning and replacement of the filter is more frequent. In addition, since the waste gas contains a large amount of toxic and harmful substances, professional personnel are required to operate with supporting equipment during cleaning and replacement. The process also requires the production equipment to be in a shutdown state, which will reduce the production efficiency of the stretch film.

[0004] Based on this, an exhaust gas treatment device for stretch film production equipment is proposed. Summary of the invention

A vertical slot 29 is opened on the connecting plate 6, and the pushing block 37 is slidably connected to the vertical slot 29. A load block 31 is slidably connected to the vertical slot 29, and a support block 32 is connected to one side of the connecting plate 6. When the pushing block 37 is not acted upon by the load block 31, the symmetrical spring 40 structure can push the deflection block 38 to separate from one end of the crank 28. In the initial state, the load block 31 falls on the support block 32. At this time, the crank 28 is in an inclined state, and the lower end of the brush rod 27 abuts against the cleaning roller 26. When the pushing block 37 rises in height, the pushing block 37 will contact the load block 31. At this time, the load block 31 is separated from the support block 32. The load block 31 is used to push the block 37, so that the deflection block 38 and one end of the crank 28 are close to each other. At this time, the crank 28 structure begins to flip, thereby flipping the brush rod 27 to a horizontal state. A slide rail 12 is connected to one side of the connecting plate 6, and a slider 13 is slidably connected to the slide rail 12. The slide rail 12 is arranged so that the slider 13 can slide horizontally and stably. An impact column 14 is connected to the slider 13.

[0020] Specifically, Figure 1As shown, a vibration spring 3 is connected to the outside of the connection frame 1, and the other end of the vibration spring 3 is connected to a fixing frame 2. The fixing frame 2 is a fixed structure. The vibration spring 3 is provided to prevent the vibration amplitude of the connection frame 1 from being too large.

[0023] Specifically, Figure 2 and Figure 3 As shown, a plug strip 7 is connected to one side of the connection frame 1, a slot 8 is provided on the connection plate 6, and the plug strip 7 is slidably connected to the slot 8. By setting the plug strip 7 structure, the position between the connection frame 1 and the connection plate 6 is stabilized when the connection frame 1 vibrates, avoiding displacement between the structures, and also reducing the load of the vibration spring 3 connecting the connection frame 1. One side of the receiving groove 24 is connected to a block structure for abutting against the connection plate 6, which has the effect of stabilizing the two connection structures.

[0024] Specifically, Figure 2 and Figure 4 As shown, a clamping bar 19 is connected to one side of the connecting plate 6, and an intermediate block 36 is connected to one side of the lifting block 20. The intermediate block 36 is slidably connected between the clamping bars 19. By setting the intermediate block 36, the stability of the lifting block 20 moving up and down along the clamping bars 19 is improved.

[0025] Specifically, Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the transmission mechanism includes a moving block 21, which is slidably connected to the lifting block 20, and a traction rod 33 is connected to one side of the moving block 21, and the traction rod 33 is vertically connected to one side of the moving block 21. A bending groove 30 is opened on the connecting plate 6, and the bending groove 30 has an "L"-shaped structure. The traction rod 33 is slidably connected to the bending groove 30, and the traction rod 33 is rotatably connected to the cylinder 9. The operator only needs to control the extension and retraction of the cylinder 9 to complete the cleaning of the filter screen 5. After the cleaning is completed, the cleaning roller 26 can also be controlled to rotate to clean the brush rod 27. The cylinder 9 is rotatably connected to one side of the connecting plate 6, and the moving block 21 is slidably connected to the toggle plate 22. The toggle plate 2 2 is connected with a docking inclined block 35 and a connecting spring 23, the other end of the connecting spring 23 is connected to the moving block 21, one end of the slider 13 is connected with a force storage inclined block 15, the connecting plate 6 is connected with a reset frame 10, the reset frame 10 is connected with a reset inclined block 11, one end of the slide rail 12 is connected with a limit block 16, a force storage spring 18 is connected between the force storage inclined block 15 and the limit block 16, the docking inclined block 35 and the reset inclined block 11 are arranged on the same vertical plane, and the toggle inclined plate 22 and the force storage inclined block 15 are arranged on the same vertical plane, the docking inclined block 35 and the reset inclined block 11 are provided with mutually matching inclined surfaces, and the toggle inclined plate 22 and the force storage inclined block 15 are provided with mutually matching inclined surfaces.

The limiting rod 17 is set to limit the force storage spring 18, so that the horizontal movement of the slider 13 is more stable.

[0027] In summary, the waste gas treatment device of a stretch film production equipment provided in this embodiment needs to connect the waste gas discharge pipe and the corrugated pipe 4 to each other when it is necessary to treat the waste gas generated in the production process of the stretch film production equipment, wherein the fixing frame 2 and the connecting plate 6 are both fixed structures, and the waste gas needs to pass through the filter screen 5 when it is discharged, and the filter screen 5 is used to adsorb and intercept dust particles and harmful substances in the waste gas. After a long period of waste gas treatment, a large amount of impurities will remain on the filter screen 5. At this time, the operation only needs to start the cylinder 9 structure to clean the filter screen 5, thereby preventing impurities from adhering to the filter screen 5, thereby ensuring that the filter screen 5 can efficiently treat the waste gas; When the cylinder 9 is contracted, the cylinder 9 pulls the traction rod 33 to slide on the bending groove 30. At this time, the traction rod 33 drives the moving block 21 to pull the lifting block 20 to rise in height. When the lifting block 20 rises in height, the crank 28 connected to one end of the lifting block 20 rises in height. At this time, when the push block 37 rises in height, the push block 37 structure will contact the load block 31. At this time, the load block 31 will squeeze the push block 37, so that the symmetrical spring 40 structure is compressed. At this time, the crank 28 structure begins to flip. During this process, the brush rod 27 can be transformed from a slanted downward state to a state where one side is facing the filter 5. At this time, one side of the brush rod 27 contacts the filter 5. As the brush rod 27 rises in height, the brush rod 27 can be used to disturb the filter 5. The bristles on the brush rod 27 can extend into the filter 5 and disturb the attached impurities, thereby preventing impurities from adhering to the filter 5. When the traction rod 33 rises to the highest point, the cylinder 9 continues to contract, the traction rod 33 begins to move horizontally, the lifting block 20 stops rising in height, and one side of the brush rod 27 abuts against the highest point of the filter screen 5. At this time, one side of the toggle plate 22 abuts against the force storage bevel block 15. When the traction rod 33 begins to move horizontally to the right, the toggle plate 22 can be used to drive the force storage bevel block 15 to move horizontally to the right. At this time, the force storage spring 18 begins to be compressed, and the moving block 21 begins to slide along the lifting block 20. The slider 13 slides along the slide rail 12 and moves toward the limit block 16. When the toggle plate 22 moves horizontally, the docking bevel block 35 moves toward the reset bevel block 11. When the inclined surfaces on the two structures abut against each other, since the reset bevel block 11 is a fixed structure, the docking bevel block 35 is squeezed by the reset bevel block 11 and its height decreases. At this time, the connecting spring 23 structure is compressed, and the toggle bevel The plate 22 structure is separated from the force storage inclined block 15. At this time, the force storage inclined block 15 is not limited by the toggle plate 22, and its structure is pushed by the force storage spring 18. At this time, one end of the impact column 14 moves rapidly toward the connection frame 1. The connection frame 1 is provided with a column structure on the side opposite to the impact column 14. The rapidly moving impact column 14 can collide with the column structure, so that the connection frame 1 structure is collided and vibrates. At this time, the vibration spring 3 can slow down the vibration of the connection frame 1, and the insertion strip 7 reciprocates in the slot 8. Since one end of the brush rod 27 is a brush structure, when the connection frame 1 vibrates left and right, its structure will not collide with the main structure of the brush rod 27. Vibration is used to separate the disturbed impurities on the filter screen 5 from the filter screen 5 under inertia, further improving the cleaning effect of the filter screen 5. The impurities separated from the filter screen 5 will freely fall into the receiving groove 24 below. After the cylinder 9 is retracted, the cleaning operation of the filter screen 5 is completed. At this time, the cylinder 9 begins to extend, and the structures connected to the connecting plate 6 begin to reset. Since the power storage inclined block 15 and the toggle inclined plate 22 are provided with inclined plane structures parallel to each other, when the two inclined planes are in contact, the power storage inclined block 15 will not prevent the toggle inclined plate 22 from resetting. When the brush rod 27 falls to the lowest position, the operator can start the cleaning roller 26 and use the cleaning roller 26 to rotate to clean the brush on the brush rod 27 to prevent impurities from adhering to the brush, thereby interfering with the next cleaning operation of the brush rod 27. One end of the cleaning roller 26 is connected to a driving motor, and the driving motor structure is not shown in the drawings. The exhaust gas treatment device can be used to regularly clean the filter 5, ensuring that the filter 5 can always be in an efficient exhaust gas treatment state, reducing the frequency of replacing or cleaning the filter 5, wherein the brush rod 27 is only arranged on one side of the filter 5, and this structural arrangement can achieve the effect of cleaning both sides of the thinner filter 5, while for the thicker filter 5, the brush rod 27 cleaning structure can be simultaneously arranged on both sides of the filter 5, thereby achieving the effect of cleaning both sides of the filter 5. The exhaust gas treatment device can seamlessly connect the vibration cleaning of the filter 5 after brushing cleaning, and the cleaning process can greatly improve the cleaning effect of the filter 5, thereby maintaining the efficient exhaust gas treatment state of the filter 5, so that the exhaust gas can be treated during the production process of the stretch film, thereby improving the production efficiency of the stretch film.
