DETAILED DESCRIPTION
[0032] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and are not used to limit the scope of the utility model.
[0033] Example 1
[0034] As Figures 1-6 shown, a medical waste extrusion crushing treatment device comprises:
[0035] The barrel 1, the first working head 2, the second working head 3, the adjusting mechanism 4, the first drive mechanism 5 and the second drive mechanism 6, the barrel 1 has a cavity with a cylindrical shape and open at both ends inside, that is, the cylindrical cavity penetrates through the entire barrel 1 along the axial direction of the barrel 1, a feed inlet 110 is arranged in the middle of the top of the barrel 1, and the feed inlet 110 is in communication with the lower end outlet of the feeding pipeline 10, a flange is arranged on the feed inlet 110 to facilitate the butt joint of the feeding pipeline 10, a discharge port 120 is arranged in the middle of the bottom of the barrel 1, and the discharge port 120 is in communication with the feed inlet of the incineration equipment 11, a flange is arranged on the discharge port 120 to facilitate the butt joint of the incineration equipment 11;
[0036] The first working head 2 and the second working head 3 are respectively arranged at both ends inside the barrel 1, that is, the first working head 2 can slide in the axial direction inside the barrel 1, and the second working head 3 can slide in the axial direction inside the barrel 1; the first working head 2 is externally arranged with the first driving mechanism 5 fixedly connected with the first working head 2, the second working head 3 is externally arranged with the second driving mechanism 6 fixedly connected with the second working head 3, the barrel 1 is externally fixed with the adjusting mechanism 4, and the first driving mechanism 5 and the second driving mechanism 6 are respectively fixedly connected with the adjusting mechanism 4; the first driving mechanism 5 is used to drive the first working head 2 to rotate inside the barrel 1, and the second driving mechanism 6 is used to drive the second working head 3 to rotate inside the barrel 1.
[0037] The adjusting mechanism 4 is used to adjust the distance between the first working head 2 and the second working head 3, for example, to adjust the distance between the first working head 2 and the second working head 3 to be smaller, and to adjust the distance between the first working head 2 and the second working head 3 to be larger; the process of reducing the distance can realize the extrusion work of the medical waste, and at the same time, the rotation driving of the first working head 2 and the second working head 3 by the first driving mechanism 5 and the second driving mechanism 6 respectively realizes the extrusion and crushing work; since the distance between the first working head 2 and the second working head 3 can be adjusted to be smaller, the medical waste after crushing treatment can be pushed into the discharge port 120 between the first working head 2 and the second working head 3 during the process of the first working head 2 and the second working head 3 approaching each other; the discharge port 120 is externally arranged with the blocking plate 7 in the form of a socket on the side surface of the discharge port 120, that is, the discharge port 120 is externally arranged with a plug plate opening, and the blocking plate 7 is inserted into the plug plate opening; the barrel 1 is externally arranged with the moving mechanism 8 connected with the blocking plate 7 and used to open and close the discharge port 120 by controlling the movement of the blocking plate 7; for the medical waste without crushing treatment, the moving mechanism 8 controls the blocking plate 7 to close the discharge port 120 to prevent it from falling into the incineration equipment 11; for the medical waste after crushing treatment, the moving mechanism 8 controls the blocking plate 7 to open the discharge port 120, and pushes the medical waste after crushing treatment into the discharge port 120 during the process of the first working head 2 and the second working head 3 approaching each other controlled by the adjusting mechanism 4.
[0038] In this scheme, the feeding pipe 10 and the incineration equipment 11 still adopt existing technology and remain unchanged. Instead, the feeding machine is replaced with a medical waste crushing and processing device. The medical waste in the feeding pipe 10 falls into the area between the first working head 2 and the second working head 3 on the material cylinder 1 through the inlet 110. The adjusting mechanism 4, the first drive mechanism 5 and the second drive mechanism 6 are activated. The first drive mechanism 5 and the second drive mechanism 6 drive the first working head 2 and the second working head 3 to rotate respectively. At the same time, the adjusting mechanism 4 controls the first working head 2 and the second working head 3 to slowly approach each other. During the slow approach, the medical waste is crushed and processed. For the crushed medical waste, the moving mechanism 8 controls the baffle plate 7 to open the discharge port 120, and the adjusting mechanism 4 controls the first working head 2 and the second working head 3 to slowly approach each other. As the first and second working heads 2 and 3 approach each other, the crushed medical waste is pushed into the discharge port 120 and finally into the incineration equipment 11. The crushing device can both crush the medical waste and push it into the incineration equipment 11. The crushing device can crush the first and second working heads 2 and 3 approach each other, so the crushing effect is better and the crushing speed is faster than that of a crusher with fixed working heads. Because the medical waste is crushed, its size will be reduced, which is beneficial for subsequent incineration, shortens the incineration time, and improves the incineration efficiency. At the same time, the crushing process can also cut the wire into multiple segments to shorten its length, so as to prevent long wires from entering the incineration equipment and causing material to stick inside the incineration equipment.
[0039] Example 2
[0040] like Figure 2 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

Sealing rings are installed in the insert plates on the side of the baffle plate 7 and the side of the discharge port 120 to prevent liquid leakage. The distance between the upper surface of the baffle plate 7 and the inner wall of the material cylinder 1 should not be too high, usually 2cm to 5cm is sufficient. If it is too high, too much medical waste will be stored, which is not conducive to crushing. The bottom wall of the drain outlet 130 is preferably flush with the upper surface of the baffle plate 7 or slightly lower than the upper surface of the baffle plate 7 so that no liquid will remain above the baffle plate 7.
[0042] Example 3

The specific number of circles can be determined according to the actual size, such as two circles, three circles, four circles, etc. The number of first crushing teeth 220 in each circle can also be determined according to the actual size, such as two, three, four, etc. When the first driving mechanism 5 is started, the first crushing disc 210 can rotate axially in the barrel 1. Under the rotation of the first crushing disc 210, the first crushing tooth 220 will also rotate, thereby crushing the medical waste by means of the first crushing tooth 220. The first crushing tooth 220 is a long columnar structure with a blade or a tooth thereon.

[0048] Embodiment 5
[0049] As shown in Figure 4 , Figure 5 , Figure 6 , this embodiment is a further improvement based on embodiment 4, which is as follows:
[0050] The multiple rows of first crushing teeth 220 on the inner side of the first crushing disc 210 and the multiple rows of second crushing teeth 320 on the inner side of the second crushing disc 310 are not axially overlapped, and the first crushing teeth 220 and the second crushing teeth 320 are spaced apart;
[0051] Specifically, it can be understood as follows: for example, the inner side of the first crushing disc 210 has three rows of first crushing teeth 220, and the diameters of each row are D1, D2, and D3, respectively, and D1 < D2 < D3; the inner side of the second crushing disc 310 has two rows of second crushing teeth 320, and the diameters of each row are D4 and D5, respectively, and D1 < D4 < D2 < D5 < D3; when the first crushing disc 210 and the second crushing disc 310 are close to a certain extent, although the first crushing disc 210 and the second crushing disc 310 are not axially overlapped, they can be partially overlapped in the vertical direction, the first crushing teeth 220 and the second crushing teeth 320 cooperate with each other to change the density of the crushing teeth, thereby better crushing the medical waste.
[0052] Embodiment 6
[0053] As shown in Figure 4 , Figure 5 , Figure 6 This embodiment is a further improvement based on embodiment 5, and the details are as follows:
[0054] The inner side of the first crushing disc 210 is outwardly recessed to form multiple rows of first annular grooves 211, and the positions of the multiple rows of first annular grooves 211 on the first crushing disc 210 correspond to the multiple rows of second crushing teeth 320 on the second crushing disc 310; the inner side of the second crushing disc 310 is outwardly recessed to form multiple rows of second annular grooves 311, and the positions of the multiple rows of second annular grooves 311 on the second crushing disc 310 correspond to the multiple rows of first crushing teeth 220 on the first crushing disc 210;
[0055] The first crushing teeth 220 can enter the second annular grooves 311, and the second crushing teeth 320 can enter the first annular grooves 211, so that the first crushing disc 210 and the second crushing disc 310 can be closer, and in the subsequent unloading process, the first crushing disc 210 and the second crushing disc 310 can act as a pushing plate under the action of the adjusting mechanism 4 to unload the crushed medical waste. In addition, during the process of the first crushing disc 210 and the second crushing disc 310 being closer, the medical waste can be further extruded and crushed.

[0056] Embodiment 7
[0057] AsFigure 4 As shown, this embodiment is a further improvement based on embodiment 6, and its specific details are as follows:
[0058] During the crushing and extrusion process, to prevent medical waste from entering the first annular groove 211 and the second annular groove 311 and thus affecting the subsequent entry of the first crushing tooth 220 and the second crushing tooth 320, a material ejection mechanism 9 is provided in both the first annular groove 211 and the second annular groove 311. When the first crushing tooth 220 and the second crushing tooth 320 have not entered the second annular groove 311 and the first annular groove 211, the material ejection mechanism 9 blocks the second annular groove 311 and the first annular groove 211. When the first crushing tooth 220 and the second crushing tooth 320 have entered the second annular groove 311 and the first annular groove 211, the material ejection mechanism 9 does not affect their entry. Furthermore, when the first crushing tooth 220 and the second crushing tooth 320 have exited the second annular groove 311 and the first annular groove 211, the material ejection mechanism 9 can push out the medical waste that has entered the second annular groove 311 and the first annular groove 211.
