Description

Technical Field

[0001] The invention relates to the technical field of rosin collection, and in particular to a high-voltage electrostatic system for rosin collection. Background Art

[0002] When printing chips, rosin is used, and the rosin waste gas generated needs to be purified and filtered by purification equipment before it can be discharged. Rosin can also be filtered by using oil fume filtering equipment. By energizing the electrode needle to generate an arc, the rosin is polarized, that is, the rosin is charged and adsorbed on the wall.

[0003] However, the traditional oil fume filtering equipment has a short time period, that is, it can continue to be used for a long time without cleaning. For the rosin processing equipment used in the factory, it needs to work uninterruptedly around the clock. Therefore, frequent cleaning plays a very important role. And when cleaning it, the time needs to be short and fast, because when the equipment is not working, the rosin gas will not be processed, which will cause the factory to be polluted. In addition, due to the limited working range of the electrode needle, the generated arc is difficult to completely cover the gas channel, so it is also necessary to increase the coverage of the electrode needle.

[0004] Therefore, it is necessary to design a high-voltage electrostatic system for rosin collection, which can perform self-cleaning in a timely and rapid manner and can increase the working range of the electrode needle. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0034] Embodiment: The present invention provides a high voltage electrostatic system for collecting rosin, such as Figure 1-3As shown, it includes a cylinder 1, a rotating mechanism 2, a rotating switching mechanism 3, an electrostatic emission mechanism 4, a scraper 10, a rosin adsorption tube 11, a heating wire 12 and a high-pressure vortex air pump 13. The rosin adsorption tube 11 is fixedly installed in the middle of the cylinder 1. The inner edge of the rosin adsorption tube 11 is used to adsorb rosin. The heating wire 12 is wound around the outer edge of the rosin adsorption tube 11. When the heating wire 12 is powered on and heated, the heat will be transferred to the rosin adsorption tube 11, and the rosin adhered to the inside of the rosin adsorption tube 11 will be heated by the heat, so that the rosin is melted. The electrostatic emission mechanism 4 is located in the middle of the rosin adsorption tube 11. The electrostatic emission mechanism 4 is used to release an arc to the rosin adsorption tube 11, and the rosin passing between the electrostatic emission mechanism 4 and the rosin adsorption tube 11 will be hit by high-voltage static electricity and generate suction, and adsorbed on the inner wall of the rosin adsorption tube 11. The scraper 10 is vertically inserted between the electrostatic emission mechanism 4 and the rosin adsorption tube 11, and one side of the scraper 10 is in contact with the inner edge of the rosin adsorption tube 11. The rotating mechanism 2 is fixedly installed on the top of the cylinder 1, and the top of the scraper 10 is connected to the rotating end of the rotating mechanism 2. The rotating mechanism 2 is used to drive the scraper 10 to rotate along the inner edge of the rosin adsorption tube 11. When the rosin is melted, the scraper 10 rotates, so that the rosin on the rosin adsorption tube 11 can be scraped off the rosin adsorption tube 11, thereby accelerating the cleaning effect. The rotary switching mechanism 3 is fixedly installed on the top of the cylinder 1. The rotary switching mechanism 3 is used to drive the rotary mechanism 2 to connect with the electrostatic emission mechanism 4, so that the electrostatic emission mechanism 4 can be driven to rotate by the rotary mechanism 2. A plurality of electrode needles 4a are arranged on the outer edge of the electrostatic emission mechanism 4. The electrostatic emission mechanism 4 rotates, which can simultaneously drive the plurality of electrode needles 4a to rotate, so that the range covered by the arc generated by the electrode needles 4a when working is increased. At the same time, the rotation of the electrode needles 4a can disturb the upward airflow, so that the gas rises in disorder, and avoids the gas not passing through the arc working area. In this way, the cleaning effect is further increased. The cylinder 1 is provided with an air inlet 1a and an air outlet 1b. The air inlet 1a is located at the bottom of the cylinder 1, and the air outlet 1b is located at the top of the cylinder 1. The air inlet of the high-pressure vortex air pump 13 is connected to the air outlet 1b through a pipeline. The high-pressure vortex air pump 13 is used to evacuate air, so that the gas can rise from bottom to top along the inside of the cylinder 1.

[0035] When the rosin needs to be electrified, the rotating switching mechanism 3 drives the rotating mechanism 2 to connect with the electrostatic emission mechanism 4, and the rotating mechanism 2 drives the electrostatic emission mechanism 4 to rotate, so that the electrode needle 4a can expand the working range and the gas is disturbed;

[0036] When the rosin adsorption tube 11 needs to be cleaned, the heating wire 12 is energized, the heating wire 12 heats the inner wall of the rosin adsorption tube 11, the rotation switching mechanism 3 drives the rotation mechanism 2 to connect with the scraper 10, the rotation mechanism 2 drives the scraper 10 to rotate, and the scraper 10 scrapes the rosin on the inner wall of the rosin adsorption tube 11. The scraper 10 is made of non-conductive material to avoid arcing and hitting the scraper 10.

[0037] In the above method, the electrode needle 4a needs to be powered off during cleaning, and the frequent startup and power failure of the high voltage will cause the electrical components inside the electrode needle 4a to burn out. However, if the power is not turned off, the rosin flowing downward during cleaning will be struck by the arc to produce coke, and some particles will be re-adsorbed on the rosin adsorption tube 11. For this reason, Figure 3 As shown, the electrostatic emission mechanism 4 also includes an installation inner tube 4b, a lifting shaft 4c and a lifting mechanism 4e. The top of the installation inner tube 4b passes through the top of the cylinder 1, and the installation inner tube 4b is rotatably connected to the cylinder 1, so that the installation inner tube 4b can rotate at the center of the cylinder 1. The lifting shaft 4c is located in the central area of ​​the installation inner tube 4b, the lifting mechanism 4e is fixedly installed on the top of the cylinder 1, and the top of the lifting shaft 4c is rotatably connected to the lifting end of the lifting mechanism 4e, so that the lifting mechanism 4e can vertically lift the lifting shaft 4c upwards. When the rotation switching mechanism 3 switches the rotation mechanism 2 to be connected with the installation inner tube 4b, the rotation mechanism 2 drives the installation inner tube 4b to rotate. When the rotation mechanism 2 drives the installation inner tube 4b to rotate, although the lifting shaft 4c rotates with the installation inner tube 4b, the lifting mechanism 4e will not be driven to rotate because the lifting shaft 4c is rotatably connected to the lifting mechanism 4e. Multiple electrode needles 4a are slidably connected to the tube wall on which the inner tube 4b is installed. A tube hole for the electrode needle 4a to slide is opened on the tube wall on which the inner tube 4b is installed. A connecting frame 4f is fixedly installed at the tail of each electrode needle 4a, and a hinged rod 4d is installed on each connecting frame 4f. One end of the hinged rod 4d is hinged to the connecting frame 4f, and the other end of the hinged rod 4d is hinged to the pulling shaft 4c. When pulled upward by the pulling shaft 4c, the pulling shaft 4c will pull the multiple electrode needles 4a inward through the hinged rod 4d for recovery, and the distance between the working end of the electrode needle 4a and the rosin adsorption tube 11 is increased, which makes it impossible to generate static electricity between the electrode needle 4a and the scraper 10, thereby preventing the rosin flowing downward from being hit by the electric arc, and there is no need to cut off the power to prevent the electrode needle 4a from being damaged.

[0038] Among them, if the high-pressure vortex air pump 13 keeps pumping air during the process of the scraper 10 cleaning the rosin, it is bound to cause the rosin gas and part of the rosin solution to be pumped upward. In the long run, more rosin will be pumped into the subsequent purification equipment, which greatly reduces the life of the subsequent purification equipment. For this reason, Figure 4As shown, it also includes a covering mechanism 5, which is installed on the installation inner tube 4b. When the rosin adsorption tube 11 needs to be cleaned, the covering mechanism 5 is used to block the gas outlet 1b. The covering mechanism 5 includes a cover plate 1 5a, a hinged rod 2 5b and a guide column 5c. The guide column 5c can be installed on the installation inner tube 4b in a horizontally slidable manner. The cover plate 1 5a is fixedly installed on the end of the guide column 5c close to 1d. One end of the hinged rod 2 5b is hinged to the guide column 5c, and the other end of the hinged rod 2 5b is hinged to the lifting shaft 4c. When the lifting shaft 4c is pulled upward, the lifting shaft 4c will push the hinged rod 2 5b to move, so that the guide column 5c pushes the cover plate 1 5a to cover the gas outlet 1b, that is, the high-pressure vortex air pump 13 can no longer extract the gas inside the cylinder 1, so as to prevent the rosin from being drawn into the subsequent purification equipment.

[0039] It should be noted that when the cover plate 5a is in the initial state (not covering the air outlet 1b), the cover plate 5a is located inside the circumference of the scraper 10, so as to avoid collision between the cover plate 5a and the scraper 10 when being rotated.

[0040] When the scraper 10 is used to clean the inner wall of the rosin adsorption tube 11, the scraper 10 rotates in an angular swinging manner to avoid collision between the scraper 10 and the guide post 5c. In order for the rotating area to cover the entire inner wall of the rosin adsorption tube 11, a semi-arc notch can be opened on the inner side of the two scrapers 10 close to the guide post 5c to avoid the guide post 5c.

[0041] When the rotating mechanism 2 drives the electrostatic emission mechanism 4 to rotate, it can rotate forward several times and then rotate reversely several times to avoid the wires from getting tangled.

[0042] In order to realize that the rotation switching mechanism 3 can switch the connection between the rotation mechanism 2 and the scraper 10 or the installation inner tube 4b, for this purpose, as shown in FIG. Figure 5 and Figure 6 The rotating mechanism 2 includes an inner gear ring 2a, an outer gear ring 2b, a gear 2c, a rotating shaft 2d and a rotating driver 2e. There are multiple scrapers 10, and the multiple scrapers 10 are fixedly installed at the bottom of the inner gear ring 2a. The outer gear ring 2b is fixedly connected to the outer edge of the mounting inner tube 4b. The gear 2c is located between the inner gear ring 2a and the outer gear ring 2b. The rotating shaft 2d is fixedly connected to the gear 2c. The rotating shaft 2d passes through the top of the cylinder 1 and is transmission-connected to the rotating driver 2e. The rotating driver 2e is fixedly installed on the rotating switching mechanism 3.

[0043] When the rosin needs to be electrified, the rotary driver 2e is pulled to move by the rotary switching mechanism 3, so that the rotary driver 2e drives the gear 2c to move through the gear 2c, that is, the rotary switching mechanism 3 pulls the gear 2c to mesh with the outer gear ring 2b, and the rotary driver 2e works, which will cause the gear 2c to drive the outer gear ring 2b to rotate, so that the inner tube 4b can drive the multiple electrode needles 4a to rotate;

[0044] When the rosin adsorption tube 11 needs to be cleaned, the rotation switching mechanism 3 pulls the gear 2c to engage with the inner gear ring 2a, and the inner gear ring 2a rotates, so that the scraper 10 can clean the rosin on the rosin adsorption tube 11.

[0045] Through the above-mentioned manner, it is possible to realize that the rotation switching mechanism 3 can switch the connection between the rotation mechanism 2 and the scraper 10 or the installation inner tube 4b.

[0046] If the cover plate 5a is not restored to its initial position, the rotating mechanism 2 will drive the electrostatic emission mechanism 4 to rotate, which will cause the guide column 5c to collide with the scraper 10 during the rotation process, and eventually cause the equipment to malfunction. In addition, the process of using the rotating switching mechanism 3 to drive the rotating mechanism 2 to move and the lifting mechanism 4e to pull the lifting shaft 4c up is controlled in steps, which will lead to poor continuity of the equipment and require waiting time, which is not conducive to quickly cleaning the inner wall of the rosin adsorption tube 11. For this reason, if Figure 6 and Figure 7 As shown, the rotary switching mechanism 3 includes a slide 3a, a slide rail 3b, an extension rod 3c and a hinge rod 3d, the slide rail 3b is fixedly mounted on the top of the cylinder 1, the slide 3a can be horizontally slidably mounted on the slide rail 3b, the rotary driver 2e is fixedly mounted on the slide 3a, the rotating shaft 2d can be horizontally rotatably mounted on the slide 3a, the extension rod 3c is fixedly mounted on the slide 3a, one end of the hinge rod 3d is hinged to the extension rod 3c, the electrostatic emission mechanism 4 includes an extension shaft 4e1 and an electric pull rod 4e2, one end of the extension shaft 4e1 is fixedly connected to the output end of the electric pull rod 4e2, the other end of the extension shaft 4e1 is rotatably connected to the top of the lifting shaft 4c, the other end of the hinge rod 3d is hinged to the extension shaft 4e1, and the electric pull rod 4e2 is fixedly mounted on the top of the cylinder 1 through a mounting frame. The extension shaft 4e1 will not be driven to rotate due to the rotation of the lifting shaft 4c. By pulling the extension shaft 4e1 upward through the electric pull rod 4e2, the extension shaft 4e1 will push the hinge rod 3 3d upward, so that the slide 3a moves toward the side away from the cylinder 1, and the rotary driver 2e is driven to move, so that the gear 2c is engaged with the inner gear ring 2a.

[0047] When the rosin needs to be electrified, the lifting mechanism 4e is in the initial position, that is, the extension shaft 4e1 does not move upward. At this time, the gear 2c is meshed with the outer gear ring 2b, the electrode needle 4a is in the state of being pushed outward, and the guide column 5c is in the state of being retracted inward;

[0048] When the rosin adsorption tube 11 needs to be cleaned, the electric pull rod 4e2 pulls the extension shaft 4e1 to move upward, and the hinge rod 3 3d pushes the rotary driver 2e outward, so that the gear 2c is meshed with the inner gear ring 2a, the electrode needle 4a is in a state of being retracted inward, and the guide column 5c is in a state of being pushed outward. Through the above working method, the continuity of the equipment is increased. It is also avoided that the rotating mechanism 2 can only drive the electrostatic emission mechanism 4 to rotate when the cover plate 1 5a returns to the initial position, and the guide column 5c is prevented from colliding with the scraper 10.

[0049] In order to reduce the bearing force of the extension shaft 4e1 during long-term discharge, as Figure 4 As shown, a support ring 4h is fixedly installed on the inner edge of the inner tube 4b, the middle part of the lifting shaft 4c passes through the support ring 4h, and a lifting ring 4s is fixedly installed on the lifting shaft 4c. When the rosin needs to be energized, the bottom of the lifting ring 4s contacts with the top of the support ring 4h, that is, through the contact between the two, the bearing force of the extension shaft 4e1 is reduced, thereby extending the life of the equipment.

[0050] like Figure 8 As shown, a waist-shaped hole is provided at the top of the cylinder 1 for the rotating shaft 2d to slide horizontally, and a cover plate 2h is fixedly provided on the rotating shaft 2d, and the cover plate 2h covers the waist-shaped hole. In this way, the rotating shaft 2d has a sliding space when switching and sliding, and the cover plate 2h seals the waist-shaped hole to prevent external gas from entering the cylinder 1.

[0051] like Figure 6 As shown, the rotary driver 2e includes a driving motor 2e1, a bevel gear 1 2e2 and a bevel gear 2e3. The driving motor 2e1 is fixedly mounted on the slide 3a, the bevel gear 2e3 is fixedly mounted on the output end of the driving motor 2e1, the bevel gear 1 2e2 is fixedly mounted on the top of the rotating shaft 2d, and the bevel gear 2e3 is meshed and connected with the bevel gear 1 2e2. By controlling the driving motor 2e1 to work, the driving motor 2e1 drives the bevel gear 2e3 to work, and the bevel gear 2e3 drives the bevel gear 1 2e2 to rotate, and finally the rotating shaft 2d is rotated.

[0052] During use, when the rosin needs to be electrified, the lifting mechanism 4e is in the initial position, that is, the lifting mechanism 4e does not move upward. At this time, the gear 2c is meshed with the outer gear ring 2b, the electrode needle 4a is in an outward push state, and the guide column 5c is in an inward retracted state. At this time, the gear 2c can be controlled to rotate, so that the gear 2c drives the outer gear ring 2b to rotate, that is, the rotation discharge of the electrode needle 4a is realized;

[0053] When the rosin adsorption tube 11 needs to be cleaned, the electric pull rod 4e2 pulls the extension shaft 4e1 upward to pull the lifting shaft 4c1 upward, and the hinge rod 3d pushes the rotary driver 2e outward, so that the gear 2c meshes with the inner gear ring 2a, the electrode needle 4a is in a state of being retracted inward, and the guide column 5c is in a state of being pushed outward. The inner gear ring 2a rotates, so that the scraper 10 rotates to clean the rosin on the rosin adsorption tube 11.

[0054] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
