Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical waste treatment, in particular to a medical waste crusher. Background Art
[0002] Medical waste is a type of waste generated by hospitals that is polluted by patients or other drugs. This type of waste is divided into general medical waste and high-risk medical waste. High-risk waste requires special treatment, while general medical waste mainly includes syringes, infusion sets and other medical consumables used for infusion or injection. When disposing of the waste, in order to reduce the amount, it is usually necessary to crush and compress it.
[0003] Currently, medical waste is shredded and compressed using a pulverizer, typically once or multiple times, to reduce particle size and compress volume. However, during this process, syringes and infusion sets contain metal needles, which are then shredded or bent and disposed of with the waste.
[0004] On the one hand, these unsorted needles are made of metal and can be recycled and smelted as scrap metal. On the other hand, if they are not sorted separately, they can easily cause contamination damage to equipment or personnel during subsequent processing. Utility Model Content
[0005] The technical problem to be solved by the utility model is to develop a medical waste crusher which can separate needle waste from medical waste for recycling of scrap metals and avoid contamination damage to equipment or personnel during subsequent medical waste treatment.
[0006] The technical solution of the utility model to solve the above technical problems is as follows:
[0007] A medical waste pulverizer includes a hopper, a casing, a blower and a slope. The hopper is provided on the casing, a discharge port is provided on one side of the bottom of the casing, a blower is provided on the opposite side of the discharge port, and a slope is provided at the bottom of the casing, the slope surface of the slope obliquely extending from the lower part of the blower to the outside of the discharge port; a first electromagnet is built into the slope; two pulverizing rollers fixedly connected to the output shaft of the motor are provided in the hopper; the motor and the first electromagnet are both electrically connected to an external power supply.
[0008] The beneficial effects of the utility model are as follows: medical waste is put into the hopper, the first electromagnet, the motor and the blower are started, the output shaft of the motor drives the crushing roller to rotate, the medical waste is crushed by the crushing roller and falls on the slope, the ferromagnetic metal needle waste is attracted by the first electromagnet and adsorbed onto the inclined surface of the slope, and the plastic waste after the syringe and infusion set are crushed is blown out from the discharge port under the action of the wind force of the blower; when the medical waste is crushed, the first electromagnet is turned off, and under the action of the wind force of the blower, the needle waste slides along the inclined surface of the slope to the outside of the discharge port for collection; by arranging the first electromagnet, the slope and the blower, the needle waste in the medical waste can be sorted for scrap metal recycling, while avoiding pollution damage to equipment or personnel during subsequent medical waste treatment.
[0009] On the basis of the above technical solution, the present invention can also be improved as follows.
[0010] Furthermore, it also includes a screen, and the lower part of the casing corresponding to the discharge port of the hopper is provided with a screen.
[0011] Furthermore, it also includes a baffle, which is arranged on the discharge port, and the bottom of the baffle is bent toward the inside of the casing.
[0012] Furthermore, it also includes a second electromagnet, which is fixedly arranged on the inner side of the baffle. The bending angle of the second electromagnet is the same as that of the baffle, and the second electromagnet is electrically connected to an external power supply.
[0013] Furthermore, the slope surface is frosted. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0019] like Figures 1 and 2As shown, Example 1 of the utility model is a medical waste shredder, comprising a hopper 1, a casing 2, a blower 4 and a slope 5. The hopper 1 is provided on the casing 2, a discharge port 21 is provided on one side of the bottom of the casing 2, a blower 4 is provided on the opposite side of the discharge port 21, and a slope 5 is provided at the bottom of the casing 2, the slope surface of the slope 5 extends obliquely from the lower part of the blower 4 to the outside of the discharge port 21; a first electromagnet 6 is built into the slope 5; two crushing rollers 11 fixedly connected to the output shaft of the motor 12 are provided in the hopper 1; the motor 12 and the first electromagnet 6 are both electrically connected to an external power supply.
[0020] Medical waste is put into the hopper 1, and the first electromagnet 6, motor 12 and blower 4 are started. The output shaft of the motor 12 drives the crushing roller 11 to rotate. After the medical waste is crushed by the crushing roller 11, it falls on the slope 5. The ferromagnetic metal needle waste is attracted by the first electromagnet 6 and adsorbed to the inclined surface of the slope 5. The plastic waste after the syringe and infusion set are crushed is blown out from the discharge port 21 under the action of the wind force of the blower 4; when the medical waste is crushed, the first electromagnet 6 is turned off, and under the action of the wind force of the blower 4, the needle waste slides along the inclined surface of the slope 5 to the outside of the discharge port 21 for collection; by setting the first electromagnet 6, the slope 5 and the blower 4, the needle waste in the medical waste can be sorted for scrap metal recycling, while avoiding contamination damage to equipment or personnel during subsequent medical waste treatment.
[0021] Embodiment 2 of the present invention provides a medical waste pulverizer. Based on Embodiment 1, it further includes a screen 3. The screen 3 is provided at the lower portion of the housing 2 corresponding to the discharge opening of the hopper 1. The screen 3 is used to screen the crushed medical waste. Medical waste that has reached a target particle size is subsequently sorted, while medical waste with a larger particle size continues to be crushed by the crushing roller 11, thereby ensuring the crushing effect of the pulverizer.
[0022] Embodiment 3 of the present invention is a medical waste pulverizer. Based on Embodiment 1, it further includes a baffle 7. The baffle 7 is provided on the discharge port 21, and the bottom of the baffle 7 is bent toward the interior of the housing 2. The baffle 7 prevents medical waste falling near the discharge port 21 from being directly blown out by the wind from the blower 4 without being sorted by the slope 5. Furthermore, after the medical waste is hit by the baffle 7, it can slide along the baffle 7 to the slope 5 for further sorting.
[0023] Embodiment 4 of the present invention provides a medical waste shredder, based on Embodiment 3, further comprising a second electromagnet 8 fixedly mounted on the inner side of a baffle 7. The second electromagnet 8 has the same bending angle as the baffle 7 and is electrically connected to an external power source. The second electromagnet 8 can absorb needles from medical waste that have fallen from the baffle 7, thereby reducing the sorting pressure of the first electromagnet 6 and improving sorting efficiency.
[0024] Embodiment 5 of the present invention is a medical waste pulverizer. Based on any one of Embodiments 1 to 4, the surface of the slope 5 is frosted. The frosting increases the roughness of the slope, thereby increasing the friction between the needle waste and the slope when the first electromagnet 6 attracts the needle waste, making the needle waste less likely to be blown away by the wind from the blower 4.
[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
