Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of plasma devices, and particularly relates to a plasma surface treatment device for plastic bottle blow molding production. BACKGROUND

[0002] The principle of plasma surface treatment is that plasma is a kind of electrically neutral material collection, which is composed of ions, electrons and neutral particles. In the process of plasma surface treatment, the plasma will transfer its energy to the molecules and atoms on the material surface when colliding with the material surface, thus a series of physical and chemical reaction processes are generated. The treatment effect of changing the surface properties of the material can be achieved by injecting particles or gas to the material surface to cause collision, scattering, excitation, rearrangement, isomerization, defect, crystallization and amorphization.

[0003] In the production process of plastic bottles, a large number of ions, excited molecules and free radicals in the plasma will act on the material surface, which can remove the original pollutants and impurities on the surface. This process can also produce etching effect, which can make the sample surface rough, form many fine pits and increase the roughness ratio of the sample surface, thereby improving the adhesion and wetting properties of the solid surface.

[0004] The gas after plasma treatment still contains some particulate pollutants and smoke dust. Therefore, the exhaust gas is sprayed by spraying water and filtered by the filler in the purification device to achieve secondary purification before being discharged into the atmosphere. However, the existing filter assembly collects particulate matter by using a flat filter screen to filter the wastewater, so that the filtered particulate matter is continuously accumulated on the filter element and is difficult to move and discharge, thereby causing the filter element to be blocked in a short time, increasing the frequency of filter element blockage, affecting normal purification work, and making it difficult to remove the pollution particulate matter. In addition, the single filter screen also bears a large working strength, which reduces the purification capacity. Furthermore, if the flow speed of the purified gas is large when being discharged, the pipeline will also be subjected to a large pressure, which will cause corresponding extrusion indentation phenomenon after long-term work. Therefore, the existing device cannot adaptively adjust and discharge the gas flow. SUMMARY

[0005] The application aims to provide a plasma surface treatment device for plastic bottle blow molding production, which solves the technical problem that the existing filter assembly uses a flat filter screen to filter wastewater, so that the filtered particulate matter is continuously accumulated on the filter element and is difficult to move and discharge, thereby causing the filter element to be blocked in a short time and increasing the frequency of filter element blockage.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Reference Manual Figure 1 As shown, the plasma surface treatment device for plastic bottle blow molding production includes:

[0039] Purification assembly 1, which includes a coarse filter 2 and a fine filter 3 placed at the upper and lower ends of the inner wall of the box. The coarse filter 2 is symmetrically arranged with respect to the center of the box, and a first rotating shaft 4 adapted thereto is installed at the center of the coarse filter 2. The purification assembly 1 is used to spray and purify the exhaust gas generated during the plasma treatment and to separate and collect particulate matter in the exhaust gas; a plasma box 5, which provides a processing space for plastic bottles and is used to etch the surface of plastic bottles; a liquid storage tank 6, which is connected to a spray pipe 7 at the top of the inner wall of the box via a delivery pump, and the liquid storage tank 6 is used to store the spray liquid;

[0040] The exhaust gas shunting assembly 8 comprises a tee pipe 9 arranged on the box body, a corresponding exhaust fan 10 is arranged at the center of the tee pipe 9, and a first uniform flow plate 11 is arranged on the inner wall of the tee pipe 9 along the center height direction. A tapered opening 12 is arranged at the inclined position of the pipe at both ends of the tee pipe 9, a sealing ring 14 fixed on a spring rod 13 is arranged on the tapered opening 12, and the spring rod 13 is fixed on the inner wall of the pipe through a support. The second uniform flow plate 16 is connected to the spring rod 13 through a synchronous rod 15. As the pressure at the exhaust port increases, the opening between the sealing ring 14 and the tapered opening 12 is closed or opened.

[0041] The liquid storage tank 6 is arranged, and the waste gas and smoke generated by the plasma reaction can be purified by the spraying effect of the water body, and the particulate matters in the waste gas can be collected and sprayed onto the purification assembly 1. A plurality of nozzles corresponding to the spraying pipe 7 are arranged on the spraying pipe 7, so that the waste gas in the box body can be effectively purified.

[0042] Referring to Figure 2 , Figure 3 and Figure 4 , one end of the fine filter screen 3 is arranged downwardly and outwardly, and the bottom end of the fine filter screen 3 is arranged on the cross beam 18 on the inner wall of the box body through the compression spring 17. The protruding part of one end of the coarse filter screen 2 is close to the circular corner 19 arranged on the inner wall of the box body, the arc-shaped rubber pad 20 is fixedly arranged on the circular corner 19, and the top end of the arc-shaped rubber pad 20 is provided with the trapezoidal block 21 arranged along the width direction of the inner wall of the box body. The downward corner of the trapezoidal block 21 is sealingly connected with the protruding part of the coarse filter screen 2.

[0043] Specifically, the trapezoidal block 21 arranged on the inner wall of the box body can automatically slide the particulate matters at the edge to the coarse filter screen 2 under the action of gravity, and can adjust the levelness of the protruding part of the coarse filter screen 2, so that the coarse filter screen 2 can maintain the corresponding horizontal position during filtering of the particulate matters, thereby preventing the gap between the trapezoidal block 21 and the coarse filter screen 2 from affecting the normal filtering and separating work of the device. Meanwhile, the circular corner 19 on the protruding part cooperates with the arc-shaped rubber pad 20 made of elastic material, so that the coarse filter screen 2 can normally rotate on the inner wall of the box body, and the structure is not stuck, thereby effectively ensuring the normal work of the device.

[0044] The spraying pipe 7 arranged on the inner wall of the box body can not only filter and purify the polluted particulate matters in the waste gas and smoke, but also can make the particulate matters on the rotating coarse filter screen 2 and the inclined fine filter screen 3 roll to the guide plate 26 under the impact of the spraying water, and finally be collected.

[0045] The cooperation of the purification assembly 1, the coarse filter screen 2 and the fine filter screen 3 can reduce the purification work of a single filter screen, and the filtering and purifying capacity is reduced. The coarse filter screen 2 can filter the impurities with large particles first, and then the impurities with small particles fall onto the fine filter screen 3 for filtering. Then the coarse filter screen 2 can be inclined and rotated downward by the transmission mechanism, and the impurities can fall onto the fine filter screen 3 by the gravity of the particles and the impact force of the spraying water. Then the impurities on the fine filter screen 3 can be vibrated and separated onto the guide plate 26 by the force of the rotating cam 33, and then collected by the recovery box 36.

[0046] The gear engagement mechanism is arranged under the action of the central gear 23, so that the first rotating gear 24 and the second rotating gear 25 at both ends rotate in opposite directions. Then the guide plate 26 and the coarse filter screen 2 can move towards the fine filter screen 3 by the mechanical transmission, so as to collect the impurities, and the rotating cam 33 can move together during the transmission, so as to vibrate and separate the impurities, thereby effectively playing the role of structural mechanical linkage. By collecting the impurities, the waste water filtered by the purification assembly 1 in the later sequence will not be polluted by mixing with the impurities in the box, thereby improving the purification effect of the device.

[0047] Reference Figure 2 , Figure 6 and Figure 7 The purification assembly 1 further comprises a driving motor 22 arranged on the outer wall of the box. The output shaft of the driving motor 22 extends to the central gear 23. The outer wall of the central gear 23 is engaged with the first rotating gear 24 and the second rotating gear 25 which move in opposite directions. The output shaft of the first rotating gear 24 is transmissionally connected to the second rotating shaft 27 on the guide plate 26 through the first conveying belt 28. The output shaft of the second rotating gear 25 is transmissionally connected to the third rotating shaft 29 on the inner wall of the box through the second conveying belt 30. The second rotating shaft 27 on the guide plate 26 is movably connected to the inner wall of the box. When the second rotating shaft 27 rotates, the guide plate 26 and the slot on the box are closed or separated.

[0048] The third rotating shaft 29 is transmissionally connected to the fourth rotating shaft 31 arranged vertically to the central direction through the third conveying belt 32. One end of the fourth rotating shaft 31 extends to the rotating cam 33 at the bottom of the fine filter screen 3. The third rotating shaft 29 is transmissionally connected to the first rotating shaft 4 through the fourth conveying belt 34 arranged alternately with the third conveying belt 32. When the driving motor 22 is started, the second rotating shaft 27 drives the guide plate 26 to rotate towards the fine filter screen 3, the first rotating shaft 4 drives the coarse filter screen 2 to rotate towards the fine filter screen 3, and the fourth rotating shaft 31 synchronously drives the rotating cam 33 to vibrate and separate the impurities on the fine filter screen 3.

[0049] The first rotating tooth 24 and the second rotating tooth 25 are arranged at both ends of the central gear 23, so that the first rotating tooth 24 and the second rotating tooth 25 can be driven in reverse by the driving motor 22, and then the first rotating shaft 4 and the second rotating shaft 27 can be driven to rotate in reverse by the driving effect, and the first rotating shaft 4 and the second rotating shaft 27 can be driven to rotate towards the fine filter screen 3, and when the filtering work is performed, the coarse filter screen 2 can be restored to the horizontal state, the guide plate 26 can be closed at the slot of the box, the first conveying belt 28 can transmit the power to the second rotating shaft 27, and the fourth conveying belt 34 can transmit the power to the first rotating shaft 4, and the guide plate 26 and the coarse filter screen 2 can be driven to rotate by the second rotating shaft 27 and the first rotating shaft 4 respectively.

[0050] Since the first rotating shaft 4 and the second rotating shaft 27 are arranged in high staggered parallel in the plane, the second conveying belt 30 and the third conveying belt 32 are arranged to convert the horizontal driving force into the vertical driving force, so that the driving force can be transmitted to the first rotating shaft 4 and the second rotating shaft 27 respectively, and the third rotating shaft 29 can transmit the driving force to the fourth rotating shaft 31 through the third conveying belt 32 during rotation, so that the rotating cam 33 on the fourth rotating shaft 31 can be driven to rotate, and the rotating cam 33 can be intermittently contacted with the inclined fine filter screen 3, so that the corresponding vibration effect can be generated, and then the particles on the fine filter screen 3 can be separated by vibration and fall into the guide plate 26, and the guide plate 26 can act as a transition medium for the particles on the fine filter screen 3 and the recovery box 36, so that the filtered particles can be transferred from the fine filter screen 3 to the recovery box 36.

[0051] Specifically, the diameters of the first rotating shaft 4 and the third rotating shaft 29 are the same, and the diameter of the third rotating shaft 29 is 20-45 cm larger than that of the fourth rotating shaft 31, and the above shape arrangement can enable the staggered third conveying belt 32 and the fourth conveying belt 34 to perform independent rotation work, so that the third conveying belt 32 and the fourth conveying belt 34 can not interfere with each other during rotation on the third rotating shaft 29, and thus the driving force of the third rotating shaft 29 can be effectively transmitted to the fourth rotating shaft 31 and the first rotating shaft 4 through the third conveying belt 32 and the fourth conveying belt 34 respectively.

[0052] A leak hole is arranged at the bottom end of the inner wall of the box below the fine filter screen 3, one end of the leak hole is connected to the liquid storage tank 6 through a pump body, and the waste water filtered and purified by the purification assembly 1 can enter the pump body through the leak hole, and a filter layer can be additionally arranged on the pipe of the pump body, so that the waste water can be treated and purified, and the waste water can be used repeatedly to improve the reusability of water resources and avoid resource waste.

[0053] Reference Figure 7 andFigure 8 The three-way pipe 9 is provided with a filler layer 35 arranged on the inner wall of the pipe at the air inlet, and the filler layer 35 can be made of activated carbon, adsorbing cotton or other purification materials, so as to ensure that the exhaust gas is safely and healthily discharged into the atmosphere.

[0054] The exhaust gas shunting assembly 8 is arranged, and the first uniform flow plate 11 in the pipe can preliminarily shunt the gas. When the wind speed is too large, the sealing ring 14 on the conical port 12 is pulled inward under the extrusion force, and the opening between the sealing ring 14 and the conical port 12 can be adaptively changed and adjusted according to the wind speed. At the same time, the length of the second uniform flow plate 16 can be extended by the pulling force of the spring rod 13, so as to expand the uniform flow area, so that the wind speed can be buffered and adjusted, thereby preventing the pipe from being subjected to a large pressure, and improving the safety of the device.

[0055] The first uniform flow plate 11 is fixedly connected to the air inlet of the inner wall of the three-way pipe 9, and can preliminarily shunt and adjust the flow of the wind. Under the action of the exhaust fan 10, when the wind force increases, the sealing ring 14 is fixed on the spring rod 13, and the spring rod 13 is fixed on the inner wall of the pipe through the support. The wind pressure pushes the sealing ring 14 to move towards the spring rod 13, and the opening can be opened. The spring rod 13 can pull the second uniform flow plate 16 connected in an extension manner, so as to expand the shunting area of the second uniform flow plate 16. In this way, the flow can be further shunted and buffered twice, so as to avoid excessive wind force. Moreover, when the wind speed continues to increase, the gap of the opening will also increase. The spring rod 13 is connected with the second uniform flow plate 16 through the synchronous rod 15 on both sides in an extension manner. As the pressure at the exhaust port increases, the opening between the sealing ring 14 and the conical port 12 is closed or opened. That is to say, the second uniform flow plate 16 is movable and connected with the spring rod 13. In this way, the second uniform flow plate 16 can move synchronously under the pulling force of the spring rod 13, and the shunting area of the second uniform flow plate 16 can be continuously expanded under the continuous pushing of the spring rod 13, so as to fully reduce the wind speed through the inclined pipe, improve the automatic flow adjustment of the device, and avoid manual adjustment and setting, which is beneficial to energy saving and environmental protection.

[0056] In the present application, the rotation of the plurality of purification assemblies 1 not only realizes the cleaning of the accumulated particles on the purification assembly 1 without taking out the purification assembly 1, greatly reduces the frequency of the blockage of the purification assembly 1, but also drives the rotation of the guide plate 26 to open the slot on the box, thereby avoiding the pollution of the filtered particles to the subsequent filtered wastewater, and achieving the unexpected technical effect of the purification assembly 1, which is also a non-obvious technical effect for the person skilled in the art.

[0057] The above merely provides the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any modification or change made by those skilled in the art within the technical scope disclosed by the present application and the inventive concept thereof should be covered within the protection scope of the present application.
