Description

Technical Field

[0001] The invention belongs to the technical field of medical waste treatment, and in particular relates to a discharging mechanism of a medical waste low-temperature pyrolysis device. Background Art

[0002] Medical waste refers to waste that is directly or indirectly infectious, toxic or otherwise harmful and is generated by medical institutions in the course of medical treatment, prevention, health care and other related activities. Medical waste is mainly divided into five categories: infectious waste, injury waste, pathological waste, pharmaceutical waste and chemical waste.

[0003] At present, low-temperature pyrolysis equipment is often used to perform low-temperature pyrolysis on medical waste. However, low-temperature pyrolysis technology has not yet been applied on a large scale. In addition, due to the complex composition of medical waste, the pyrolysis process is difficult to control, and the composition after pyrolysis is uncertain. Therefore, whether the sealing and safety of the residue after pyrolysis can be guaranteed during the discharge process has become a key point in the current low-temperature pyrolysis technology.

[0004] To this end, the inventors considered designing a discharge mechanism for a low-temperature pyrolysis device for medical waste to improve the sealing and safety of the pyrolysis residue during discharge. Summary of the invention

[0005] In view of the above-mentioned defects in the prior art, the present invention provides a discharging mechanism of a medical waste low-temperature pyrolysis device, comprising an upper discharging pipe and a lower discharging pipe, which are arranged vertically, a first push pipe and a first inner discharging pipe are passed through the interior of the upper discharging pipe, and the first push pipe is fixedly connected to the left side of the first inner discharging pipe, an upper discharging bin is connected to the upper part of the right end of the upper discharging pipe, a lower discharging bin is connected to the right end of the upper discharging pipe, a first power device is arranged at the left end of the upper discharging pipe, the first power device is provided with a first output end fixedly connected to the first push pipe, and the first power device can drive the first push pipe to reciprocate left and right in the upper discharging pipe through the first output end.

[0006] A second push tube and a second inner discharge tube are inserted into the interior of the lower discharge tube, and the second push tube is fixedly connected to the left side of the second inner discharge tube. The upper part of the right end of the lower discharge tube is connected to the bottom of the lower discharge bin. A second power device is provided at the left end of the lower discharge tube. The second power device is provided with a second output end fixedly connected to the second push tube, and the second power device can drive the second push tube to reciprocate left and right in the lower discharge tube through the second output end.

[0007] Optionally, the outer shape of the first inner discharge pipe matches the inner cavity of the upper discharge pipe, and the outer shape of the second inner discharge pipe matches the inner cavity of the lower discharge pipe.

[0008] Specifically, this can improve the sealing between the first inner discharge pipe and the upper discharge pipe, and between the second inner discharge pipe and the lower discharge pipe.

[0009] Optionally, the upper discharge pipe and the first power device, as well as the lower discharge pipe and the second power device, are sealedly connected via flanges and flange sealing sleeves.

[0010] Specifically, this can ensure the sealing between the upper discharge pipe and the first power device, and between the lower discharge pipe and the second power device.

[0011] Optionally, sight glasses are provided on the upper parts of the upper discharge bin and the lower discharge bin.

[0012] Specifically, the sight glass facilitates observation of the discharge of the pyrolysis residue.

[0013] Optionally, the lower discharge bin is located on the right side of the upper discharge bin, and a discharge port is provided at the right end of the lower discharge pipe.

[0014] Optionally, the top end of the upper discharge bin is connected to the discharge end of the low-temperature pyrolysis equipment through a connecting pipe.

[0015] Optionally, the first power device and the second power device may adopt electric push rods, electric cylinders, hydraulic cylinders or propulsion cylinders.

[0016] The present invention also includes other components that enable the discharge mechanism of a medical waste low-temperature pyrolysis device to function normally, which are all conventional technical means in the art. In addition, the devices or components not limited in the present invention all adopt conventional technical means in the art.

[0017] The working principle of the present invention is that the medical waste after pyrolysis becomes pyrolysis residue, which is discharged from the discharge end of the low-temperature pyrolysis equipment and enters the upper discharge bin through the connecting pipe. At this time, the first inner discharge pipe is blocked at the bottom of the upper discharge bin to play a sealing role, and the first power device is started to drive the first push pipe to reciprocate left and right, thereby driving the first inner discharge pipe to reciprocate left and right. During the movement of the first inner discharge pipe, the pyrolysis residue in the upper discharge bin falls into the upper discharge pipe and is pushed into the lower discharge bin. Similarly, at this time, the second The inner discharge pipe is blocked at the bottom of the lower discharge bin to play a sealing role. After the first inner discharge pipe in the upper discharge pipe completes a reciprocating motion, the second power device is started to drive the second push pipe to reciprocate left and right, thereby driving the second inner discharge pipe to reciprocate left and right, so that the pyrolysis residue in the lower discharge bin falls into the lower discharge pipe and is pushed out of the lower discharge pipe. In this way, the upper discharge pipe and the lower discharge pipe perform alternating left and right reciprocating motions to ensure that at least one place provides sealing for the pyrolysis system during the discharge of the pyrolysis residue.

[0018] The beneficial effects of the present invention are:

[0019] (1) The present invention ensures that at least one point of the pyrolysis residue provides sealing for the pyrolysis system during the discharge process by alternately performing left and right reciprocating motions in the upper discharge pipe and the lower discharge pipe, thereby improving the sealing and safety of the slag discharge of the entire pyrolysis system.

[0020] (2) The upper discharge pipe and the lower discharge pipe, as well as the upper discharge bin and the lower discharge bin are staggered, which provides convenience for the pyrolysis residue to fall layer by layer and facilitates continuous discharge. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] A second push tube 13 and a second inner discharge tube 14 are penetrated inside the lower discharge tube 2, and the second push tube 13 is fixedly connected to the left side of the second inner discharge tube 14, the upper part of the right end of the lower discharge tube 2 is connected to the bottom of the lower discharge bin 8, and a discharge port is provided at the right end of the lower discharge tube 2, and a second electric cylinder 12 is provided at the left end of the lower discharge tube 2, the second electric cylinder 12 is provided with a second output end fixedly connected to the second push tube 13, and the second electric cylinder 12 can drive the second push tube 13 to reciprocate left and right in the lower discharge tube 2 through the second output end.

[0030] In addition, the shape of the first inner discharge pipe 4 matches the inner cavity of the upper discharge pipe 1 , and the shape of the second inner discharge pipe 14 matches the inner cavity of the lower discharge pipe 2 .

[0031] It is understandable that this can improve the sealing between the first inner discharge pipe 4 and the upper discharge pipe 1 , and between the second inner discharge pipe 14 and the lower discharge pipe 2 .

[0032] The upper discharge pipe 1 and the first electric cylinder 11 , as well as the lower discharge pipe 2 and the second electric cylinder 12 , are sealedly connected via a flange 5 and a flange sealing sleeve 6 .
