Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a crusher for discarded syringes used in hospitals and the like.

``Conventional technology'' Conventional show crushers, cone crushers, impact crushers, etc. are used to crush rocks that are easily crushed, so they are used to crush small, disposable objects that are less likely to be crushed.
When syringes, needles, drip devices, etc. are put into the crusher, they are ejected and discarded without being crushed, so there have been cases where the discarded syringes are collected and misused. Problems The object of the present invention is to simply and sufficiently crush the above-mentioned syringes.

``Means for Solving the Problems'' The present invention provides a rotating rotor in a machine casing having an input port at the top and a discharge port at the bottom, and a plurality of impact surfaces protruding from the outer periphery of the rotor. A fixed receiving plate having an inner end in contact with the outer end of the impact surface is provided on the machine casing side, shearing blades are formed at the outer end and the inner end, respectively, and the direction of the outer end shearing blade and the direction of the inner end shearing blade are It is composed of waste shredders such as syringes, which are characterized by the fact that they intersect with each other.

"Operation" Therefore, when the rotating rotor 4 is rotated at a high speed and objects to be crushed, such as a waste syringe 26, a hypodermic needle 27, and an intravenous drip device 28, are inputted from the input port 2, the plurality of impact surfaces 5 apply an impact to these objects to be crushed. give. Among the objects to be crushed, hard glass or synthetic resin syringes 26, etc. are crushed by the impact, and are deformed and collided with the fixed receiving plate 6, which further crushes the syringe needles 27 and their heads 27, metal It is manufactured by IV drip equipment 28
Since they are made of soft synthetic resin, they are less likely to be crushed by the impact, and are sheared by the shearing blades 7.8 at the outer and inner ends. During shearing, since the directions of the shearing blades 7.8 intersect with each other, the object to be crushed that falls between the shearing blades 7.8 is sandwiched between the shearing blades 7.8 and shredded by the action of the scissors. The crushed and shredded materials are discharged from the lower discharge port 3.

``Example'' A machine case 1 of a crusher is supported on a machine stand 9, an input hopper 10 is arranged in an input port 2 provided at the upper part of the machine case 1, and a discharge port 3 is connected to the lower part through a passage 11. It is formed. In this manner, the rotating rotor 4 is pivotally supported in the center of the machine casing 1. Although this rotor 4 is horizontal, it may also be vertical. A plurality of impact hammer plates 12 are protruded from the outer circumferential surface of the rotor 4, and an impact surface 5 is formed substantially in the radial direction on the rotational direction side of the plate 12. A fixed receiving plate 6.6 having an inner end in contact with the outer end of the impact surface 5 is provided on the machine casing Nla, and an adjacent receiving plate 6.6 is provided on the machine casing Nla.
6 and the distance between adjacent impact surfaces 5.5 are shown in Figures 2 and 4.
As shown in the figure, the upper end of the impact surface 5.5 is formed to simultaneously contact the adjacent receiving plate 6.6. Then, shearing blades 7.8 are formed at the outer and inner ends, respectively, and the direction of the outer end shearing blades 7 is made obliquely intersecting the central axis of the rotor 4 (an inclination of about 5/100 is sufficient as shown in FIG. 3). ), and the direction of the inner end shearing blade 8 is arranged parallel to the central axis of the rotor 4, so that the double-edged blade 7.8
cross each other (Figure 3). The inner shearing blades 8 may be arranged obliquely. The directions of the outer end shearing blades 7.7 adjacent to each other are formed in opposite directions to each other in order to balance high-speed rotation (this state is shown in No. 11W). In addition, the horizontal axis of the high-speed rotation center of the motor 4 is indicated by 13 in the figure, 14
15 is an auxiliary high-speed rotating rotary interposed in the passage 11, 15 is an impact blade surface of the blade, and 16 is a fixed receiving blade in contact with the outer end of the same blade surface 15, and the height t of the blade surface 15 is smaller than the diameter t of the injection needle head. The head of an unfractured syringe needle can be crushed.

A drive pulley provided on the 3-piece output shaft 22, 24 a drive belt,
The opening/closing lid of the 25 tf input hopper IO, 26 a disposable syringe, a 27 IIi injection needle, 28 intravenous drip tools, and 29 crushed material containers.

"Effects" Since the present invention is configured as described above, it is possible to quickly and reliably shred the waste syringes 26, injection needles 27, IV equipment 28, etc. discarded from hospitals, health centers, etc. into small pieces at hospitals, health centers, etc. It is possible to prevent the above-mentioned waste products from being misused.
