Description

Technical Field

[0001] The utility model relates to the technical field of medical waste treatment, in particular to a cutting structure for a diaper pulverizer. Background Art

[0002] Hospital waste refers to all waste that needs to be discarded and cannot be reused in hospitals, including biological and non-biological waste, as well as domestic waste. Medical waste refers to waste generated during the diagnosis, treatment, and nursing of patients.

[0003] Medical waste may contain a large number of pathogenic microorganisms and harmful chemicals, and even radioactive and damaging substances. Therefore, medical waste is an important risk factor causing disease transmission or related public health problems.

[0004] Diapers and disposable nursing pads are care products that patients often use during hospital care. They are usually discarded directly after use and then transported by hospital staff to special medical waste treatment stations and other treatment sites for disposal.

[0005] Traditional diapers and disposable nursing pads are directly thrown into the waste incinerator for incineration, but because diapers and other medical waste contain a lot of water, it will bring inconvenience to incineration.

[0006] Therefore, how to centrally and harmlessly treat medical waste such as diapers in a simpler, safer and more efficient way is a difficult problem that needs to be solved urgently.

[0007] There is a diaper grinder on the market that uses a grinding blade or a grinding roller to cut and grind diapers into small pieces for convenient incineration. However, the existing diaper grinder has a large structure, occupies a large area, and has no sealing device. It can usually only be used in places such as garbage incineration plants and is not convenient for use in hospitals.

[0008] Existing diaper crushers usually use evenly distributed cutting blades to cut diapers into strips, which are then fed into a crushing chamber and cut into small particles by crushing blades. The cutting blades and crushing blades will continue to be worn out over a long period of time, resulting in damage that affects the crushing effect. Utility Model Content

[0009] The purpose of the utility model is to provide a cutting structure for a diaper pulverizer. The utility model has the advantages that the hospital can conveniently and harmlessly treat diapers, and is not easily damaged and will not affect the pulverization effect.

[0010] The technical solution of the utility model: a cutting structure for a diaper pulverizer, comprising a machine body, a top frame arranged on the top of the machine body, a water tank arranged on the back of the machine body, a pulverizing cylinder detachably arranged in the machine body and corresponding to the top frame, a sealing cover rotatably opened and closed and arranged above the middle of the top frame, a cutting unit arranged in the pulverizing cylinder, a cylinder mounting unit arranged in the machine body for installing the pulverizing cylinder, and a spray system arranged in the machine body and respectively connected to the water tank, the sealing cover and the pulverizing cylinder; the cutting unit comprises a static cutting ring detachably arranged on the inner wall of the lower part of the pulverizing cylinder, a rotating head rotatably arranged in the middle part of the static cutting ring, and a pulverizing motor arranged below the pulverizing cylinder and connected to the rotating head; cutting modules corresponding to the static cutting ring are evenly distributed on the outer edge of the upper part of the rotating head, and grabbing blades corresponding to the cutting modules are evenly distributed on the middle edge of the upper part of the rotating head; there is a certain gap between the cutting module and the static cutting ring.

[0011] In the aforementioned cutting structure for the diaper shredder, a removable front cover plate is provided on the front side of the machine body, and a foot pedal groove with an infrared sensing unit installed is provided in the middle of the front side of the bottom; the top frame is made of antibacterial material, and a feeding port corresponding to the sealing cover is provided in the middle of the top frame, and a sealing ring is provided below the feeding port; a control panel is provided above the rear end of the top frame, and a control circuit board is provided below the control panel; a locking cover unit is distributed on the inner side of the feeding port, and the locking cover unit includes a door lock controller, a micro switch and an electric latch; a latch hole corresponding to the electric latch is provided around the sealing cover.

[0012] In the aforementioned cutting structure for the diaper shredder, the static cutting ring includes a plurality of cutting blocks evenly spaced apart; each of the cutting modules includes a mounting seat and a cutting head detachably mounted on the mounting seat, the cutting head being a square block, and the cutting head corresponds to the static cutting ring.

[0013] In the aforementioned cutting structure for the diaper shredder, the rotating head is a circular mounting plate, the middle part of the rotating head is concave, a grabbing plate is detachably provided above the middle part of the rotating head, and the grabbing blades are evenly distributed on the outer edge of the grabbing plate; there is a certain gap between the grabbing blade and the mounting seat, and one side of the end of the grabbing blade is arc-shaped.

[0014] In the aforementioned cutting structure for a diaper pulverizer, the output shaft of the pulverizing motor is detachably and rotatably connected to the rotating head via a connecting structure.

[0015] Compared with the prior art, the pulverizer of the present application is composed of a machine body, a top frame, a sealing cover, a water tank, a pulverizing cylinder, a cutting unit and a spraying unit. It is only necessary to throw diapers and disposable nursing pads into the pulverizer and then cover the sealing cover. The spraying unit sprays the pulverizing cylinder from top to bottom and forms a downward negative pressure inside, thereby driving the diapers to press down on the cutting unit. The cutting unit rotates continuously to cut and pulverize the diapers into small particles, which are then discharged from the pulverizer driven by the spraying water.

[0016] A cutting unit consisting of a static cutting ring, a rotating head, a cutting module and a grabbing blade is used to replace the traditional shearing blade and crushing blade. The cutting module consists of a mounting seat and a cutting head. The cutting head and the static cutting ring are square blocks and cutting blocks respectively, and neither has a sharp edge. The edge will not be damaged during long-term use, and the crushing effect will not be affected.

[0017] Therefore, the utility model has the advantages that the hospital can conveniently and harmlessly dispose of diapers, and the diapers are not easily damaged and the crushing effect is not affected.

[0018] By adopting this application, the crushing of diapers and the cleaning of the inside of the crusher can be automatically completed without the need for excessive operations by the staff. The entire crushing process is completely closed inside to ensure that the external environment will not be polluted;

[0019] The present application utilizes an infrared sensing unit at the bottom to sense the pedal action to open and close the sealing cover, thereby reducing contact between people and the device and effectively reducing cross infection. BRIEF DESCRIPTION OF THE DRAWINGS
