Description

Medical waste treatment device {Apparatus for treating medical waste}

The present invention relates to a medical waste treatment apparatus, and more particularly, to a medical waste treatment apparatus in which a cutter block for crushing and pulverizing waste can be easily replaced.

In general, medical waste (hereinafter abbreviated as 'waste') disposed of in hospitals or sanatoriums contains pathogens, and such wastes are sterilized and disposed of by law.

As a device for treating medical waste, Korean Patent Application Laid-Open No. 2003-0007363 and Korean Patent Publication No. 2011-0011214 are disclosed as prior art.

The above prior art has a system for crushing or pulverizing the waste while sterilizing the waste.

However, the waste crushing and crushing devices of the prior art have a structure in which the structure is fixed or the waste is crushed by a screw blade. In general, medical waste is made of plastic or vinyl material that can be easily crushed, but it is difficult to cut clothes or needles that need to be cut through a crushing device without a sharp blade. In particular, when it is wound around the screw blade without being cut, the operation of the processing device is stopped and the waste wound on the screw blade is manually removed, and then the processing device is operated.

In order to overcome this problem, instead of using a two-dimensional screw blade, a rotary grinder in which a plurality of blades form the outer circumferential surface of a cylindrical shaft is implemented three-dimensionally, and a device for pulverizing, cutting, and crushing waste more efficiently has emerged.

However, the rotary grinder that continuously pulverizes, cuts, and crushes waste, even though it is made of an alloy material with excellent durability, is prone to wear due to its functional characteristics, and it is cumbersome to replace it periodically.

In particular, the rotary crusher currently used in waste treatment equipment, etc., must be disassembled for replacement or repair, and after replacing the rotary crusher, it is necessary to check whether the operation of the rotary crusher is normal after reassembly. There are difficulties in disassembling the device again.

In addition, if the rotary grinder is not replaced or repaired in a timely manner, the specifications prescribed by the law that can be landfilled or incinerated due to the nature of medical waste cannot be met. can occur

A medical waste treatment device according to an embodiment of the present invention is a device capable of safely processing wastes that are likely to cause secondary infection, such as hospitals. Most of the medical waste currently generated is collected at a specialized collection company, sterilized so that there is no risk of infection, and then incinerated or buried. However, since the collection process is cumbersome and wastes with a high possibility of infection must be stored in the hospital until they are collected, there is always a risk of infection of patients, guardians, and medical staff caused by pathogens.

The medical waste treatment device according to an embodiment of the present invention relates to a device capable of processing medical waste that is actually generated by itself, and the disassembly and assembly of the cutter block, which must be replaced for management and maintenance of the device, is required. It relates to an easy medical waste treatment device.

Briefly explaining the general medical waste treatment apparatus shown in FIG. 1 , the medical waste contained in the basket 1 is moved to the upper part of the apparatus by the lifting device, and the waste contained in the basket 1 is put into the hopper 2 . do. The medical waste put into the hopper 2 falls to the cutter block 100, and the cutter block 100 crushes the inputted medical waste into small pieces.

The pieces of medical waste shredded to a predetermined size are placed on the screw-type rotary transfer unit and rise, and various pathogens are removed by the sterilizing device 3 while ascending. The piece of medical waste rising from the sterilization treatment device 3 is again put into the drying unit 4 and discharged to the discharge unit 5 after removing a significant portion of the moisture component remaining inside. The discharged medical waste residues are incinerated or landfilled for final treatment.

Through this series of treatment processes, medical waste is directly input, and the cutter block 100 that crushes it must be periodically replaced and inspected, and for this purpose, the medical waste treatment device must be disassembled. In particular, it takes a long time to replace or check the cutter block 100 because it is necessary to disassemble the large-volume hopper 2 as shown in FIG. 1 and also disassemble the motor and reducer in some cases, and the cutter block 100 ), we have to go through a complex decomposition process to find the problem.

As shown in Figs. 3 and 4, the cutter body 120 is an area for crushing the waste input through the open upper surface of the block housing 110, and as shown in Figs. 3 and 4, the cutter body 120 has a cylindrical shape. A first shaft 121a and a second shaft 122a rotating in opposite directions together with the first shaft 121a are formed. The first blade 121b formed on the outer peripheral surface of the first shaft 121a and the second blade 122b formed on the outer peripheral surface of the second shaft 122a rotate in an interdigitated manner, and the first blade 121b And the waste is crushed between the first blade (121b), the second blade (122b) rotates as the waste is input to the second blade (122b).

The first blade 121b and the second blade 122b are formed obliquely along the longitudinal direction of the cylindrical shape in the form of a rotating blade in the form of a screw, and the first shaft 121a and the first blade 121b may be integrally configured. , preferably configured to be decomposable with each other.

In particular, the first shaft 121a and the first blade 121b are formed in the longitudinal direction inside the first fixing groove 121d and the first blade 121b formed in the longitudinal direction of the outer circumferential surface of the first shaft 121a. The first protruding pieces 121c are coupled to each other. The coupling of the first fixing groove 121d and the first protruding piece 121c may induce the first blade 121b to rotate together with the rotation of the first shaft 121a, and the second shaft 122a ) and the second blade 122b are coupled to the second fixing groove and the second protruding piece 122c so that the second blade 122b can rotate together with the rotation of the second shaft 122a.

The first shaft 121a constituting the cutter body 120 protrudes through the gearbox 140 and rotates by the external rotational force, that is, the rotational force transmitted by the motor 10, and the second shaft accommodated in the gearbox. A gear (not shown) provided on one side of the shaft 122a is rotated.

In the gearbox 140, the first gear provided on one side of the first shaft 121a and the second gear provided on one side of the second shaft 122a are meshed with each other, and the first gear provided on one side of the first shaft 121a is engaged with each other. When the first gear rotates, the second gear rotates together in the gearbox 140 to rotate the second shaft 122a.

The sieve 160 discharges waste crushed to a predetermined size or less in the lower portion of the cutter body 120, or the waste before being crushed to a predetermined size or less is put back between the first blade 121b and the second blade 122b. make it possible

The sieve 160 may be composed of an iron mesh having a predetermined interval, but is not necessarily limited thereto.

The center groove 170 is formed in the lower center of the lower plate 111 and coincides with the center guide 250 formed in the support structure 200 when the cutter block 100 is combined with the support structure 200 . make it Due to the center groove 170 and the center guide 250 , the rotary wheel 150 of the cutter block 200 can move without departing along the transfer rail 300 , and the cutter block 100 moves to the support structure 200 . ) can be combined in place.
