Description

Technical Field

[0001] The present invention belongs to the technical field of medical device recycling, and specifically relates to a medical device part recycling and processing device. Background Art

[0002] The waste generated after the use of medical devices includes packaging materials, used instruments, etc. These wastes can be recycled through classification, cleaning, and appropriate treatment methods. There may also be valuable resources in the recycled wastes, such as recyclable metals, plastics, etc. The metals and plastics in medical device parts are often in a connected state, and they need to be crushed and then screened and separated. However, the crushing process of medical device parts is a sensitive and strictly controlled process because of the harmful substances it may contain, the risk of biological contamination, and the complexity of the materials.

[0003] When the existing equipment crushes medical device parts, the crushing chamber is in an open state, and the heat generated by the crushing roller will volatilize the harmful substances on the surface into the air, seriously affecting the personal safety of the staff. Secondly, a small amount of dust and particles will also be generated during the crushing process, and the open crushing chamber allows them to directly diffuse into the air, causing serious environmental pollution. Summary of the Invention

[0004] The purpose of the present invention is to provide a medical device part recycling and processing device to solve the problems raised in the above background art.

A feed inlet is provided at the rear of the control housing. An exhaust pipe is fixedly connected to the front of the housing.

[0007] Preferably, the heater includes a heating housing. A plurality of rectangular plates are fixedly connected to the middle of the heating housing. A plurality of through holes are provided in the middle of the rectangular plates. A heating wire is fixedly connected to the middle of the plurality of rectangular plates. The heating housing is fixedly connected to the inner wall of the housing. The right side of the motor sleeve is fixedly connected to the inner wall of the housing.

[0008] Preferably, the collection chamber is slidably connected to the housing with good sealing performance. The right side of the air pump is fixedly connected to the inner wall of the housing. The left and right ends of the guide plate one, guide plate two, and guide plate three are all fixedly connected to the inner wall of the housing.

[0009] Preferably, the two spur gears are meshed with each other, and the two crushing rollers are adapted to each other.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. In the present invention, by the rotation of the upper shift lever and the lower shift lever, the upper and lower sliding plates are staggered to move forward and backward. While ensuring the feeding of medical equipment parts, the volatilized toxic substances, generated dust and particles cannot be discharged from the feed inlet into the atmosphere, thus ensuring the personal safety of the staff.

[0014] 2. The hot gas discharged through the gas distribution shell in the present invention blows the plastic of the medical device parts forward and drops into the interior of the front collection chamber, while the metal falls into the interior of the rear collection chamber due to inertia. At the same time, the hot gas inactivates the viruses on the surfaces of the plastic and the metal. Subsequently, the gas after separating the plastic and the metal continues to move upward to inactivate the viruses on the surfaces of the medical device parts that will enter the interior of the shell. While completing the separation of the metal and the plastic, the viruses that may survive on the surfaces of the medical device parts are inactivated, greatly reducing the risk of biological contamination and solving the problem of relatively high risk in the recycling process of existing medical device parts.

[0023] Among them, it further includes a control shell 22 fixedly connected to the upper surface of the shell 1. Two sliding cavities 23 are formed inside the control shell 22. A control board 24 is slidably connected inside the sliding cavity 23. A spring 25 fixedly connected to the control shell 22 is fixedly connected to the front end of the control board 24. A sliding plate 26 is fixedly connected to the rear end of the control board 24. A control rod 27 is rotatably installed in the middle of the control shell 22.

A lower bevel gear 31 is meshed with the right side of the upper bevel gear 30. A transmission rod 32 is fixedly connected to the middle of the lower bevel gear 31. A third pulley 33 is fixedly connected to the right end of the transmission rod 32. A second belt 34 is connected between the third pulley 33 and the rear second pulley 15 for transmission. A feed inlet 35 is formed at the rear of the control shell 22. An exhaust pipe 36 is fixedly connected to the front of the shell 1. The function is that, through the rotation of the upper shift lever 28 and the lower shift lever 29, the upper and lower sliding plates 26 are staggered to move forward and backward, while ensuring the feeding of medical equipment parts, the volatilized toxic substances, generated dust and particles cannot be discharged into the atmosphere from the feed inlet 35, thus ensuring the personal safety of the staff. Moreover, when the lower sliding plate 26 opens for feeding, the slightly discharged gas is sucked back into the interior of the shell 1, further avoiding the diffusion of toxic substances, generated dust and particles into the air, and solving the problem of serious environmental pollution caused by the prior art.

[0024] Among them, the heater 6 includes a heating shell 61. A plurality of rectangular plates 62 are fixedly connected to the middle of the heating shell 61. A plurality of through holes 63 are formed in the middle of the rectangular plates 62. A heating wire 64 is fixedly connected to the middle of the plurality of rectangular plates 62. The heating shell 61 is fixedly connected to the inner wall of the shell 1. The function is that the heating wire 64 is powered on for heating, and at the same time the air pump 8 works. Air is inhaled through the suction pipe 13 and the motor sleeve 10, and the heat generated during the operation of the drive motor 11 will be taken away during the process, so as to dissipate heat from the drive motor 11. The inhaled air enters the interior of the heating shell 61 from the intake pipe 7. Due to the arrangement of the through holes 63, the gas will stay in the interior of the heating shell 61 for a relatively long time, and after being fully heated by the heating wire 64, it enters the connecting pipe 5 and finally is discharged from the air distribution shell 4 into the interior of the shell 1, while distinguishing plastics and metals, inactivating the viruses on the surfaces of plastics and metals and the viruses on the surfaces of medical equipment parts.

[0025] Among them, the collection chamber 3 is slidably connected to the housing 1 with good sealing performance. The right side of the air pump 8 is fixedly connected to the inner wall of the housing 1. The left and right ends of the first guide plate 19, the second guide plate 20, and the third guide plate 21 are all fixedly connected to the inner wall of the housing 1. The right side of the motor sleeve 10 is fixedly connected to the inner wall of the housing 1. The transmission rod 32 is rotatably connected to the control housing 22. The upper shift lever 28 and the lower shift lever 29 are collinear but in opposite directions. The upper shift lever 28 is coplanar with the upper control plate 24, and the lower shift lever 29 is coplanar with the lower control plate 24. The upper end of the suction pipe 13 has two air inlets. The upper air inlet is communicated with the feed port 35 between the two sliding plates 26. The sliding plates 26 and the control housing 22 have good sealing performance. Its function is to intermittently input the medical device parts to be pulverized from the feed port 35 onto the upper surface of the upper sliding plate 26. Since the upper shift lever 28 and the first guide plate 19 rotate, the rotation of the upper shift lever 28 will push the upper control plate 24 to move forward, thereby driving the upper sliding plate 26 to move forward and compress the upper spring 25, so that the medical device parts on the upper surface of the sliding plate 26 are pushed by the control housing 22 to the upper surface of the lower sliding plate 26. At this time, since the rotating lower shift lever 29 is located at the notch of the lower control plate 24, when the upper sliding plate 26 opens, the lower sliding plate 26 is still in the closed state. When all the medical device parts on the upper surface of the sliding plate 26 fall onto the upper surface of the lower sliding plate 26, the upper shift lever 28 rotates, and the upper spring 25 will push the upper sliding plate 26 to gradually close. When the upper shift lever 28 and the lower shift lever 29 rotate 180 degrees, the lower shift lever 29 will drive the lower sliding plate 26 to move forward, so that the medical device parts fall onto the upper surfaces of the third guide plate 21 and the second guide plate 20, thus avoiding the diffusion of toxic substances, generated dust and particles into the air.

[0026] Working principle:

[0027] Before the present invention is used, both sliding plates 26 are in the closed state. The collection chamber 3 is located inside the housing 1 with good sealing performance. The outlet of the exhaust pipe 36 is connected to an existing gas treatment device;

[0028] When the present invention is in use, the heating wire 64 is energized for heating, and at the same time the air pump 8 works. Air is inhaled through the suction pipe 13 and the motor sleeve 10 and enters the inside of the heating housing 61 from the air inlet pipe 7. Due to the setting of the through holes 63, the gas will stay in the heating housing 61 for a relatively long time, and after being fully heated by the heating wire 64, it enters the connecting pipe 5 and finally exits from the air distribution housing 4 and enters the inside of the housing 1;

[0029] The driving motor 11 operates, and the output shaft drives the first pulley 12 to rotate. The first pulley 12 drives the second pulley 15 at the front side to rotate through the first belt 18. The rotation of the second pulley 15 drives the front-side rotating shaft 14, the crushing roller 17, and the spur gear 16 to rotate. Since the spur gear 16 at the rear side meshes with the spur gear 16 at the front side, the rotating shaft 14, the crushing roller 17, and the second pulley 15 at the rear side rotate. The second pulley 15 at the rear side drives the third pulley 33 to rotate through the second belt 34. The rotation of the third pulley 33 drives the transmission rod 32 and the lower bevel gear 31 to rotate. The rotation of the lower bevel gear 31 drives the upper bevel gear 30 meshing above it to rotate. The rotation of the upper bevel gear 30 drives the control rod 27, the upper shift lever 28, and the lower shift lever 29 to rotate. The medical device parts to be crushed are intermittently fed from the feed port 35 onto the upper surface of the upper sliding plate 26. Since the upper shift lever 28 and the first guide plate 19 rotate, the rotation of the upper shift lever 28 will push the upper control plate 24 forward, thereby driving the upper sliding plate 26 to move forward and compress the upper spring 25. As a result, the medical device parts on the upper surface of the sliding plate 26 are pushed by the control housing 22 to the upper surface of the lower sliding plate 26. Since the rotating lower shift lever 29 is located at the notch of the lower control plate 24 at this time, while the upper sliding plate 26 is opened, the lower sliding plate 26 remains closed. When all the medical device parts on the upper surface of the sliding plate 26 have fallen onto the upper surface of the lower sliding plate 26, the upper shift lever 28 rotates, and the upper spring 25 will push the upper sliding plate 26 to gradually close. When the upper shift lever 28 and the lower shift lever 29 rotate 180 degrees, the lower shift lever 29 will drive the lower sliding plate 26 to move forward, so that the medical device parts fall onto the upper surfaces of the third guide plate 21 and the second guide plate 20, and finally fall onto the middle part of the crushing roller 17 with opposite rotation directions, and thus are crushed. The crushed medical device parts slide down from the upper surface of the first guide plate 19. The hot gas discharged from the air distribution housing 4 will blow the plastic of the medical device parts to fall forward into the inner part of the front collecting cavity 3, while the metal falls into the inner part of the rear collecting cavity 3 due to inertia. At the same time, the hot gas will inactivate the virus on the surfaces of the plastic and the metal;

[0030] Since heat is generated while the crushing roller 17 crushes the medical device parts, the toxic substances contaminated on the medical device parts are volatilized and float upward. At the same time, a small amount of dust and particles are generated, and the gas after the separation of the plastic and the metal continues to move upward to inactivate the virus on the surface of the medical device parts entering the inside of the housing 1, and drives the volatilized toxic substances, dust, and particles to be discharged from the exhaust pipe, and finally are processed by the existing gas treatment device.
