Description

Technical Field

[0001] The present invention belongs to the technical field of medical waste, and in particular relates to a medical waste disposal device. Background Art

[0002] Medical waste refers to contaminated waste produced by hospitals that has come into contact with patients' blood, flesh, etc. The medical inspection report of the national health department shows that due to the characteristics of medical waste such as space pollution, acute infection and latent pollution, the harmfulness of its viruses and bacteria is dozens, hundreds or even thousands of times that of ordinary domestic waste, which will cause serious pollution to the environment. Therefore, medical waste needs to be disposed of. There are many technologies for treating medical waste. According to different treatment principles, they can generally be divided into sterilization and disinfection, incineration, plasma, pyrolysis and sanitary landfill.

[0003] At present, incineration is generally used to dispose of medical waste. Because some medical waste is large in size, it will affect the incineration speed. Therefore, the medical waste must be decomposed and cut before incineration. However, the current device cannot completely ensure that the size of the decomposed and cut medical waste meets the standards during the decomposition and cutting of the medical waste. A large volume of medical waste that does not meet the standards will be generated, which will affect the incineration and is not conducive to sorting it out. Therefore, a medical waste disposal device is proposed. Summary of the invention

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described 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.

[0036] Reference Figure 1-10The embodiment of the present invention provides a medical waste disposal device, comprising a decomposable cutting shell 13, a closing piece 14, a decomposable cutting column 16, a motor 18 and a delivery shell 20; the decomposable cutting shell 13 is arranged at one end of the front of the assembly frame 12, the head of the decomposable cutting shell 13 is reserved with a delivery hole 132, and the tail of the decomposable cutting shell 13 is reserved with a discharge hole 133; a plurality of connecting holes 135 are arranged at the front head of the decomposable cutting shell 13, and a maintenance hole 136 is reserved at the front of the decomposable cutting shell 13; the closing piece 14 is a curved rectangle, and the closing piece 14 is connected to the decomposable cutting shell 13 In the front, the decomposition and cutting column 16 is connected to the decomposition and cutting shell 13, and the left side of the decomposition and cutting column 16 is connected to the chain 19. The inner wall of the decomposition and cutting shell 13 and the inside of the closing plate 14 are both hollow structures. During the period when the cutting knife 17 inside the decomposition and cutting column 16 decomposes and cuts the medical waste, the decomposition and cutting shell 13 and the closing plate 14 can weaken the sound generated during the decomposition and cutting of the medical waste, and have the ability to weaken the decibel. The motor 18 and the chain 19 are connected to each other, the delivery shell 20 is connected to the head of the decomposition and cutting shell 13, and the filter box 21 is connected to the tail of the decomposition and cutting shell 13.

[0037] The decomposition and cutting column 16 is rotatably installed in the decomposition and cutting shell 13. A plurality of assembly chambers 163 are reserved in a ring shape on the decomposition and cutting column 16. The assembly chambers 163 in the decomposition and cutting column 16 are respectively connected to the two upper and lower delivery holes 132 and the discharge holes 133 of the decomposition and cutting shell 13. The cutting knives 17 are respectively connected to the plurality of assembly chambers 163 on the decomposition and cutting column 16 via fasteners. When the decomposition and cutting column 16 in the decomposition and cutting shell 13 pulls the cutting knives 17 to rotate, the cutting knives 17 decompose and cut the medical waste put into the delivery holes 132, and the medical waste after decomposition and cutting is discharged through the discharge holes 133.

[0038] A maintenance hole 136 is reserved on the front side of the decomposition and cutting shell 13, and the closing piece 14 is embedded in the maintenance hole 136 area on the front side of the decomposition and cutting shell 13, and can be connected by snaps, etc. The tail of the closing piece 14 is screwed to the front side of the decomposition and cutting shell 13, and the connection hole 2 142 reserved at the head of the closing piece 14 and the connection hole 1 135 reserved on the front side of the decomposition and cutting shell 13 are interconnected. The fastening screw 15 is connected in the connection hole 2 142 and the connection hole 1 135. After the cutting knife 17 in the decomposition and cutting column 16 is damaged after long-term operation, the closing piece 14 on the front side of the decomposition and cutting shell 13 can be opened, and the cutting knife 17 in the decomposition and cutting column 16 can be disassembled and replaced, thereby ensuring that the cutting knife 17 in the decomposition and cutting column 16 can continue to be able to decompose and cut medical waste.

[0039] The left side of the back side of the decomposition and cutting shell 13 is fixedly connected to the motor 18 via fasteners, and the sprocket 2 182 is assembled on the rotating rod of the motor 18. The sprocket 162 is installed on the left side of the decomposition and cutting column 16. The sprocket 162 is rotatably installed on the left side of the decomposition and cutting shell 13. The sprocket 2 182 is connected to the sprocket 1 162 via the chain 19, and can pull the decomposition and cutting column 16 in the decomposition and cutting shell 13 to rotate quickly through the chain 19 connected to the motor 18, thereby achieving the purpose of decomposing and cutting medical waste in the decomposition and cutting shell 13.

[0040] A delivery shell 20 is installed at the head of the decomposing and cutting shell 13, and a plurality of oblique containment sheets 202 are installed inside the head of the delivery shell 20 at the same intervals. The tail of the delivery shell 20 and the delivery hole 132 at the head of the decomposing and cutting shell 13 are interconnected, so that medical waste can be placed into the decomposing and cutting shell 13 through the delivery shell 20. The containment sheet 202 inside the delivery shell 20 covers the medical waste ejected from the delivery hole 132 at the head of the assembly frame 12, thereby preventing the medical waste from ejecting from the delivery hole 132 at the head of the decomposing and cutting shell 13 to the outside, thereby polluting the surrounding environment.

[0041] The filter box 21 contacts the tail of the discharge hole 133, a filter is installed at the tail of the filter box 21, the rectangular frame 23 is connected to the tail of the filter box 21 via fasteners, and the tail of the rectangular frame 23 is connected to the receiving shell 24, so that the medical waste leaking out of the discharge hole 133 can be caught through the filter box 21, and the medical waste after decomposition and cutting can be separated through the filter at the tail of the filter box 21, so that the medical waste with small volume and meeting the standards can fall into the receiving shell 24, and the medical waste with large volume and not meeting the standards can be separated in the filter box 21, so that the operator can send the medical waste that does not meet the standards in the filter box 21 back into the decomposition and cutting shell 13, so as to ensure that the decomposition and cutting of the medical waste are thorough, which is conducive to subsequent incineration and other operations.

[0042] The four corners of the leakage hole 133 at the tail of the disassembled cutting shell 13 are respectively reserved with a through hole 134, the filter box 21 contacts the tail of the leakage hole 133, and the four corners of the head of the filter box 21 are respectively screwed with the tightening parts 22, the tightening parts 22 are connected to the through hole 134, and the tightening parts 22 are rotated and pressed to connect to the head of the through hole 134. When the filter box 21 contacts the tail of the leakage hole 133, the tightening parts 22 are connected to the through hole 134, and the tightening parts 22 are respectively rotated to make the tightening parts 22 press and connect to the head of the through hole 134, and the four corners of the filter box 21 are constrained by the tightening parts 22 to ensure the fixed connection, which is convenient for the removal and assembly of the filter box 21.

[0043] During operation, the motor 18 is driven through the chain 19 to rotate the decomposition and cutting column 16 in the decomposition and cutting shell 13. The operator delivers the medical waste into the decomposition and cutting shell 13 through the delivery shell 20. The decomposition and cutting column 16 drives the cutting knife 17 to rotate, and the medical waste falling from the delivery hole 132 is decomposed and cut. The containment sheet 202 in the delivery shell 20 covers the medical waste jumping out of the delivery hole 132 at the head of the decomposition and cutting shell 13, and prevents the medical waste from jumping out of the delivery hole 132 at the head of the decomposition and cutting shell 13 to the outside, so that the medical waste after decomposition and cutting is discharged from the discharge hole 133. The medical waste discharged from the discharge hole 133 is caught by the filter box 21. The operator rotates the four tightening parts 22 periodically. , separate and take away the tail of the self-draining hole 133 of the filter box 21, and separate the decomposed and cut medical waste through the filter plate at the tail of the filter box 21, so that the small-volume medical waste that meets the standards falls into the receiving shell 24, and the large-volume medical waste that does not meet the standards is separated in the filter box 21. This is conducive to the operator to send the medical waste that does not meet the standards in the filter box 21 back into the decomposition and cutting shell 13 to ensure that the medical waste is completely decomposed and cut. After the cutting knife 17 in the decomposition and cutting column 16 is damaged after long-term operation, the front sealing piece 14 of the decomposition and cutting shell 13 is opened, and the cutting knife 17 in the decomposition and cutting column 16 is disassembled and replaced to ensure the ability of the cutting knife 17 in the decomposition and cutting column 16 to decompose and cut medical waste.

[0044] The difference from the above is that the filter box 21 is also equipped with an adaptive discharge assembly mechanism, which includes a filter, a spiral beryllium copper wire 13111, a support platform 13112, a discharge cover 13114, a traction wire 13115, and a support plate 13116. The filter includes a filter 1 at the head and a cooperative filter C12124 at the tail. The filter 1 includes a filter A12122 and a filter B12124 that cooperates with the filter A12122. 23, one side of the filter A12122 is screwed and installed on one side of the inner wall of the filter box 21, one side of the filter B12123 can be screwed and installed on the other side of the inner wall of the filter box 21, the filter A12122 and the filter B12123 are installed face to face, the collaborative filter C12124 can be screwed and installed on the inner wall of the filter box 21, the filter A12122, the filter B12123 and the collaborative filter C12124 are respectively located in the horizontal plane of the high and low distribution, and the spiral beryllium copper wire 13 The tail of 111 is connected to the other side of the collaborative filter C12124, the head of the spiral beryllium copper wire 13111 is connected and abuts against the other side of the filter B12123, the other side of the filter B12123 is at the tail of the filter A12122, and abuts against the other side of the tail of the filter A12122 due to the elastic force of the filter A12122, the discharge cover 13114 can be rotatably installed on one side wall of the filter box 21, and the support platform 13112 is installed on The inner wall of the filter box 21, and the supporting platform 13112 is located at the tail of the other side of the collaborative filter C12124 for supporting the collaborative filter C12124, one end of the head of the traction wire 13115 is connected to the head of the discharge cover 13114, and the tail of the traction wire 13115 is connected to one side of the collaborative filter C12124, and the supporting plate 13116 is located at the tail of the discharge cover 13114, for supporting one side of the collaborative filter C12124 rotating toward the tail.

[0045] The high-position filter disc A12122 and the filter disc B12123 form a complete high-position filter disc structure, dividing the inside of the filter box 21 into two cavities distributed high and low. The other sides of the filter disc A12122 and the filter disc B12123 can be pressed against each other and tightly connected, so that they can be opened to form an open discharge area. The cooperative filter disc C12124 is located at the tail of the open discharge area and is adaptably installed. The distance between the two ends of filter A12122 on one side and the other side of the filter box 21 does not exceed the distance between the two ends of filter B12123 on one side and the other side of the filter box 21. The distance between the two ends of filter A12122 on one side and the other side of the filter box 21 is one third to two fifths, for example, one half, of the distance between the two ends of filter B12123 on one side and the other side of the filter box 21. Filter B12123 includes a high filter and a low filter connected to the rear edge of the high filter. The high filter and the low filter form a filter structure in which the filter is overlapped and connected to each other.

[0046] Elastic parts are installed on the rotation axis of filter A12122 and filter B12123. The elastic parts are spiral beryllium copper wires and can generate opposite torque when the rotation deformation is restored. A constraint plate 13117 is installed in the area near the rotation axis at the tail of filter A12122 to constrain the rotation range of filter A12122 toward the tail and also support filter A12122.

[0047] The size of the collaborative filter C12124 is slightly larger than that of the filter A12122, and is installed at the tail of the filter A12122. The rotation axis of the collaborative filter C12124 is installed in an area close to the other side of the collaborative filter C12124, that is, it is installed at a position farther from the discharge cover 13114, so that the medical waste that does not meet the size and is filtered and left on the collaborative filter C12124 can press the collaborative filter C12124, thereby allowing one side of the collaborative filter C12124 to swing toward the tail. A fence is installed at the edge area of ​​the other side of the collaborative filter C12124.

[0048] During routine operations, medical waste is a smooth fall stage, according to Figure 8 It is shown that the high-position filter and the collaborative filter C12124 are both in the horizontal plane;

[0049] according to Fig. 9 The demonstration is that after a long period of operation, medical waste that does not meet the size will be filtered out and form an obstacle on the head wall of the high-position filter, so that the gradually accumulated medical waste will gather on the high-position filter and cannot fall smoothly. During the period when the accumulated medical waste is greater than the amount it can carry, because filter B12123 is subjected to a larger external force than filter A12122, filter B12123 will compress the spring to swing more to the tail than filter A12122, and an open discharge area will be formed between filter A12122 and filter B12123. Filter A12122 and filter B12123, especially the medical waste on filter B12123, roll onto the collaborative filter C12124. Fig.10 It is shown that during the period when the mass of the medical waste that does not meet the size on the collaborative filter C12124 is greater than the bearing capacity, the collaborative filter C12124 swings toward the tail and allows one side to be supported on the supporting plate 13116. During the swinging, the discharge cover 13114 is pulled open by the traction wire 13115, thereby allowing the medical waste that does not meet the size on the collaborative filter C12124 to discharge out of the filter box 21. In this way, the purpose of discharging the accumulated medical waste that cannot fall from the filter, that is, the medical waste that does not meet the size, is achieved. During this period, the spiral beryllium copper wire 13111 lifts the filter B12123 toward the head, shrinking the discharge open area, thereby reducing the discharge of the high-position filter during the discharge of the collaborative filter C12124.

[0050] The present invention can properly dispose of the medical waste accumulated on the filter disc that cannot fall off normally, so as to achieve the purpose of self-discharge of the device, avoid the accumulation of medical waste that is not large enough to pass through the filter disc, causing the device to fail to work normally, and make the operation of the device more stable.

[0051] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
