Description

Technical Field

[0001] This utility model relates to the field of rosin recycling technology, specifically a device for recycling and reusing rosin processing waste. Background Technology

[0002] The source of rosin is limited. In many rosin processing plants, due to the lack of effective recycling technology and equipment, the rosin residue discharged from the high-level pot is simply discarded. In fact, a lot of rosin that has not been distilled and extracted is still left in these residues. Simply discarding them not only wastes resources but also causes environmental pollution. Therefore, the slag-throwing machine came into being.

[0003] Existing centrifuges for extracting rosin from high-level boiler residue use a centrifuge drum to centrifuge the rosin residue. The rosin in the residue is then sprayed onto the inner wall of the drum through the discharge port. A rotating scraper scrapes the rosin on the inner wall, facilitating its discharge from the outlet. However, because the scraper and the centrifuge drum are fixed in place, a large amount of rosin impurities adhere to the scraper's surface over time. When not in use, these impurities can stick the scraper to the inner wall of the drum. When needed, this causes significant resistance to the starting of the geared motor, resulting in a sudden increase in the motor's load and causing considerable damage. Furthermore, the extracted rosin still contains small particles of residue, creating significant problems for subsequent deep filtration.

[0004] Chinese patent discloses a device for recycling and re-extracting rosin processing tailings (authorization announcement number CN219187309U). This patented technology uses electric heating tubes and heaters. While the rosin is centrifuged at high speed, the telescopic rod extends outward due to the centrifugal force, which in turn drives the scraper to come into contact with the inside of the device. This allows the rosin splashed onto the inner wall to be scraped off while rotating at high speed, reducing the amount of residue and improving the recycling effect. Moreover, the electric heating tube connected inside the scraper can heat the entire scraper and maintain it at a suitable temperature to prevent the rosin in contact with it from solidifying on its surface, ensuring that the rosin can be fully removed. In addition, the heater on the inner wall of the device can also heat the surface, further reducing the amount of rosin residue, so that the rosin can be fully removed and re-extracted. This prevents the phenomenon of the scraper sticking to the inner wall due to long-term disuse, reducing the impact on the device. It has the advantages of preventing solidification and minimizing the impact on operation.

[0005] The resin in the resin residue will be discharged outward through the surface pores. The discharged resin will move outward all the way until it is discharged from the outlet and collected by personnel. The discharged resin will be filtered through a filter screen to remove the residue particles, thereby improving the actual re-extraction effect.

[0006] However, it has certain drawbacks: it removes residual particles from rosin through a filter screen, and after a long period of use, a large number of residual particles will accumulate on the surface of the same filter screen, causing blockage of the filter holes and thus affecting the normal discharge of rosin; and when replacing the filter screen, it is necessary to stop the machine for a long time and wait, which affects the recycling progress. Utility Model Content

[0007] The purpose of this invention is to provide a device for recycling and reusing rosin processing waste, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A device for recycling and reusing rosin processing waste includes a recycling cylinder, a first motor fixedly connected to the lower surface of the recycling cylinder, a centrifuge cylinder fixedly connected to the output end of the first motor, a discharge pipe connected to the inside of the recycling cylinder fixedly connected to the lower end of the left side surface of the recycling cylinder, two filter plates movably connected through the upper surface of the discharge pipe from left to right, and a scraping mechanism provided at the upper end of the left side surface of the centrifuge cylinder.

[0010] A rack is fixed to the upper end of the filter plate, and a connecting rod is movably connected to the inside of the rack on one side of the filter plate. A driving mechanism is provided on the upper surface of the discharge pipe between the two filter plates.

[0011] As a further embodiment of this utility model: the scraping mechanism includes an L-shaped plate, a sliding tube is fixedly connected through the inside of the L-shaped plate, a spring is fixedly connected to the right side surface of the inside of the sliding tube, a sliding rod is fixedly connected to the left end of the spring, and a scraper is fixedly connected to the left end of the sliding rod.

[0012] As a further embodiment of this utility model: the driving mechanism includes a connecting plate, a second motor is fixedly connected to the front surface of the connecting plate, and a gear is fixedly connected to the output end of the second motor.

[0013] As a further embodiment of this utility model: the centrifuge cylinder is located inside the recovery cylinder, the filter plate is movably located inside the discharge pipe, and the lower end of the connecting rod is fixed to the upper surface of the discharge pipe.

[0014] As a further embodiment of this utility model: the right end of the L-shaped plate is fixed to the left side surface of the centrifuge cylinder, and the slide rod is slidably connected to the inside of the slide tube.

[0015] As a further embodiment of this utility model: the lower end of the connecting plate is fixed to the upper surface of the discharge pipe, the gear is located between the two racks, and the gear is meshed with the two racks.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model is equipped with a scraping mechanism. The spring in the scraping mechanism is stretched under the action of centrifugal force, so that the scraper adheres to the inner wall of the recycling cylinder and follows the rotation of the centrifugal cylinder to clean the inner wall of the recycling cylinder, removing the adhering rosin. When not in use, the spring returns to its original state and drives the scraper away from the inner wall of the recycling cylinder.

[0018] 2. This utility model uses filter plates to filter small particulate impurities in the recovered rosin. The second motor drives the gear to rotate, which can realize the staggered lifting of the two racks, thereby quickly switching between the two filter plates and avoiding clogging caused by using the same filter plate for a long time. Moreover, when cleaning one filter plate, the other filter plate can be used normally without the need for long-term downtime. Attached Figure Description

A scraper 11 is fixedly connected to the left end of the sliding rod 10.

[0031] Under normal conditions, the scraper 11 does not contact the inner wall of the recycling cylinder 1; under the action of centrifugal force, the spring 9 will stretch, causing the scraper 11 to contact the inner wall of the recycling cylinder 1, and follow the rotation of the centrifuge cylinder 3 to clean the inner wall and remove the adhering rosin. Its principle is the same as that of the telescopic rod in the comparative document.

[0037] The working principle of this utility model is as follows: When in use, the operator puts the rosin-containing waste material into the centrifuge cylinder 3 and then closes the cylinder lid; the first motor 2 drives the centrifuge cylinder 3 to rotate, throwing out the rosin from the rosin-containing waste material. The rosin is filtered through the filter plate 5 in the discharge pipe 4 and then discharged; during this process, the spring 9 is stretched by centrifugal force, causing the scraper 11 to contact the inner wall of the recovery cylinder 1, cleaning off the rosin adhering to the inner wall of the recovery cylinder 1; after a period of time, the second motor 16 drives the gear 17 to rotate clockwise, driving the left rack 12 to rise and the right rack 12 to fall, thereby moving the left filter plate 5 out of the discharge pipe 4 and moving the right filter plate 5 into the discharge pipe 4, realizing the rapid switching of the two filter plates 5; the operator can disassemble the left filter plate 5 for cleaning.
