Description

Technical Field

[0001] This utility model belongs to the field of medical waste plastic treatment technology, specifically relating to a vibrating automated sorting device for small impurities in medical waste plastic. Background Technology

[0002] Small impurities in medical waste plastics, such as glass fragments, metal particles, cotton swab fragments, and drug residue particles, if not screened, may cause equipment wear during subsequent crushing and melting processes, such as scratching crusher blades and clogging melting pipes, or even causing equipment failure, reducing processing efficiency and increasing maintenance costs.

[0003] To prevent the aforementioned problems, a vibrating screen is used to separate impurities from medical waste plastic. When using a vibrating screen to separate impurities from medical waste plastic, the operator feeds the impurities into the vibrating screen through the feed inlet. However, this process has a drawback: due to the large quantity of medical waste plastic fed at once, it tends to become entangled and pile up on the screen. Even with normal screening, it takes time to separate the piled-up plastic. During this vibration period, the accumulated plastic cannot be effectively separated, resulting in a poor final screening effect. Utility Model Content

[0004] The purpose of this invention is to provide an automated vibrating sorting device for small impurities in medical waste plastics. This device addresses the problem that when a large quantity of medical waste plastics is fed in at once, it tends to become entangled and pile up on the vibrating screen. Even with normal screening, it takes time to separate the piled-up medical waste plastics. During this vibration period, the accumulated waste plastics cannot be effectively screened, resulting in a poor final screening effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibrating automatic sorting device for small impurities in medical waste plastic, including a vibrating sorter. A first screen is installed in the screening area near the top inside the vibrating sorter, and a second screen is installed at the bottom of the first screen. A micro-material outlet is provided at the bottom of the discharge port of the second screen, and one end of the micro-material outlet is welded to the outer wall at the bottom of the opening end of the vibrating sorter.

[0006] A feeding hopper is installed on the surface of the vibrating separator at the end away from the micro-material outlet. A side plate is detachably installed in the opening on one side of the feeding hopper by bolts. A first bearing is fitted into the outer wall of the side plate facing the inside of the feeding hopper. A second bearing is fitted into the inner wall of the feeding hopper away from the side plate. A crossbar is rotatably installed between the second bearing and the first bearing.

[0007] In order to prevent medical waste plastic from falling off the end of the partition when it is placed in the area between the six partitions of the crossbar, the medical waste plastic vibration type small impurity automatic sorting device of this utility model preferably has six partitions evenly spaced on the outer wall of the crossbar, and an end plate is installed between each two adjacent partitions.

[0008] The inside of the feeding hopper is fixedly installed with two limiting plates by bolts, and the opposite side of the two limiting plates is in contact with the outer wall of one end of the partition.

[0009] In order to enable the partition to be installed on the crossbar in a detachable structure, as the medical waste plastic vibration type small impurity automatic sorting device of this utility model, preferably, six sets of insertion ports are equally spaced on the outer wall of the crossbar. Each set of insertion ports consists of two rectangular slots. A plug is inserted into the two rectangular slots in the same set, and the other end of the two plugs is fixedly connected to one side of the outer wall of the same partition.

[0010] The crossbar has six threaded grooves arranged in a ring on the outer wall facing the side plate. Each threaded groove has a long bolt threaded inside it, and the end of the long bolt is completely inside the threaded groove after installation.

[0011] When each of the long bolts is installed into the corresponding threaded groove, it will simultaneously pass through two inserts, which are fixedly installed in the socket by the long bolts.

[0012] In order to enable the rocker arm to rotate and drive the crossbar to rotate, in the present invention, the medical waste plastic vibration type small impurity automatic sorting device, preferably, has a rocker arm movably arranged on one side of the side plate, and one end of the rocker arm is connected to the end of the crossbar that extends into the inner ring of the first bearing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] During operation, the operator rotates the crossbar and its six upper partitions using a crank, adding the medical waste plastic to be screened into the feeding hopper. As the waste plastic enters the hopper, the crossbar rotates the corresponding partitions to the waste plastic's falling area. The falling waste plastic is then partially caught by the crossbar and partitions, and the caught portion is conveyed to the bottom opening of the hopper by the rotation of the crossbar and partitions. This allows the waste plastic to be distributed onto the first screen. This structure effectively prevents excessive accumulation of large amounts of waste plastic onto the first screen when added at once, thus improving the efficiency of subsequent screening.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 The present invention provides the following technical solution: a medical waste plastic vibration type small impurity automatic sorting equipment, including a vibration sorter 1, a first screen 2 installed in the screening area near the top inside the vibration sorter 1, a second screen 3 installed at the bottom of the first screen 2, a micro material outlet 4 provided at the bottom of the discharge port of the second screen 3, and one end of the micro material outlet 4 welded to the outer wall at the bottom of the opening end of the vibration sorter 1;

[0025] The screen opening size on the first screen 2 is larger than that on the second screen 3. During use, the medical waste plastic to be screened is fed into the first screen 2 through the feeding hopper 5. At this time, under the action of the vibrating separator 1, the medical waste plastic piled on the first screen 2 will gradually disperse, and at the same time, it will gradually move towards the discharge port of the first screen 2.

[0026] During the screening process of the vibrating separator 1, small impurities in the medical waste plastic will fall down from the first screen 2 and the second screen 3 in sequence according to their size. In this way, the vibrating separator 1 can automatically complete the sorting of small impurities in the medical waste plastic.

[0027] A feeding hopper 5 is installed on the surface of the vibrating separator 1 at the end away from the micro-material outlet 4. A side plate 6 is detachably installed in the opening on one side of the feeding hopper 5 by bolts. A first bearing 7 is fitted into the outer wall of the side plate 6 facing the inside of the feeding hopper 5. A second bearing 9 is fitted into the inner wall of the feeding hopper 5 away from the side plate 6. A crossbar 8 is rotatably installed between the second bearing 9 and the first bearing 7.

[0028] The detachable design of the side panel 6 allows it to be disassembled as needed during use, which allows the long bolt 84 to be installed or removed from one side of the crossbar 8, thereby meeting the requirements for disassembling and installing the partition 81.

[0029] Preferably, six partitions 81 are installed at equal intervals on the outer wall of the crossbar 8, and an end plate 82 is installed between each two adjacent partitions 81;

[0030] Two limiting plates 51 are fixedly installed inside the feeding hopper 5 by bolts. The two limiting plates 51 are in contact with the outer wall of one end of the partition plate 81 on opposite sides.

[0031] In practical use, the limiting plate 51 can be provided with a notch at its bottom according to the size of the round rod at the end of the crossbar 8. In this way, the limiting plate 51 can be installed in the feeding hopper 5 by inserting it downwards and then fixed with screws.

[0032] Preferably, six sets of sockets 85 are equally spaced on the outer wall of the crossbar 8. Each set of sockets 85 consists of two rectangular slots. A plug block 83 is inserted into each of the two rectangular slots in the same set, and the other end of the two plug blocks 83 is fixedly connected to one side of the outer wall of the same partition 81.

[0033] The crossbar 8 has six threaded grooves 86 arranged in a ring on the outer wall facing the side plate 6. Each threaded groove 86 has a long bolt 84 threaded inside it, and the end of the long bolt 84 is completely set inside the threaded groove 86 after installation.

[0034] When each long bolt 84 is installed into the corresponding threaded groove 86, it will simultaneously pass through two inserts 83. The inserts 83 are fixedly installed in the socket 85 by the long bolts 84.

[0035] In practical use, when installing the partition 81, align the two inserts 83 on one side with the corresponding two sockets 85 on the crossbar 8, and then install the long bolt 84 into the threaded groove 86 on one side of the crossbar 8. After alignment, the long bolt 84 will fix the two inserts 83 in the sockets 85, thus securely installing the partition 81 on the crossbar 8.

[0036] Preferably, a rocker arm 61 is movably provided on one side of the side plate 6. One end of the rocker arm 61 is connected to one end of the crossbar 8 that extends into the inner ring of the first bearing 7. When in use, the rocker arm 61 is rotated, which causes the crossbar 8 to rotate, thereby allowing the crossbar 8 to rotate between the first bearing 7 and the second bearing 9.

[0037] In practical use, the operator rotates the crossbar 8 and its six partitions 81 via the rocker arm 61, at which point the medical waste plastic to be screened is added into the feeding hopper 5. As the medical waste plastic enters the feeding hopper 5, the crossbar 8 will rotate the corresponding partitions 81 to the area where the medical waste plastic falls.

[0038] The falling medical waste plastic is then partially caught by the crossbar 8 and the corresponding partition 81. The caught portion of the medical waste plastic is then conveyed to the bottom opening of the feeding hopper 5 as the crossbar 8 and partition 81 rotate. This allows the medical waste plastic to be distributed onto the first screen 2 in portions. During use, this structure effectively prevents excessive stacking of large quantities of medical waste plastic onto the first screen 2 when a large amount is fed at once, thereby improving the efficiency of subsequent screening.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
