Description

Technical Field

[0001] This invention relates to the field of laboratory waste treatment technology, specifically to an integrated device for sterilizing and reducing the volume of solid waste. Background Technology

[0002] In the process of veterinary drug production, various experiments are required. During these experiments, researchers often wear disposable protective equipment and use disposable laboratory equipment. The current standard procedure involves classifying and collecting these wastes, then temporarily storing them in the laboratory for periodic collection by a professional waste disposal company. However, this storage in the laboratory poses safety risks. Laboratory equipment accumulates various solutions during experiments, and prolonged storage in the laboratory can easily lead to bacterial growth and cross-contamination, which can then infect researchers.

[0003] To address the issue of bacterial growth on discarded laboratory equipment, some laboratories have adopted small-scale high-temperature steam sterilization equipment. However, after sterilization, the waste remains damp. If not bagged, this moisture allows airborne bacteria to re-adhere and multiply. Furthermore, the high temperature immediately after steam sterilization prevents immediate bagging; allowing the waste to cool naturally provides another opportunity for airborne bacteria to attach to and proliferate.

[0004] To address this, an integrated solid waste sterilization and volume reduction treatment device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated solid waste sterilization and reduction treatment device, which automatically packages and seals laboratory waste with a sealing film after steam sterilization to prevent bacteria from growing again after sterilization.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An integrated solid waste sterilization and volume reduction treatment device includes a housing with an end cap rotatably mounted on its top. A sterilization chamber is located inside the housing, and a cylindrical outer cylinder is disposed within the sterilization chamber. The outer cylinder is not sealed at both ends and is fixedly connected to the inner wall of the sterilization chamber via connecting columns. An inner cylinder is detachably disposed inside the sterilization chamber, also not sealed at both ends. A support ring is provided at the top of the inner cylinder for abutting against the top of the outer cylinder. The inner and outer cylinders are concentrically spaced. Two hooks are symmetrically arranged at the bottom of the support ring near the inner cylinder. A cylindrical sealing film is fitted over the outer side of the inner cylinder, with the sealing film aligned along the axis of the inner cylinder. The components are arranged in a continuous, integrated stack. The encapsulation film is located between the outer and inner cylinders. Two hooks simultaneously hook the top of the encapsulation film. Two heat-sealing blades are symmetrically arranged below the outer cylinder. One heat-sealing blade has a cutting hot wire, and the other heat-sealing blade has a cutting groove corresponding to the cutting hot wire. Inside the sterilization chamber, two first drive components are arranged corresponding to the two heat-sealing blades. The first drive components are used to drive the heat-sealing blades to move horizontally. A support platform is arranged below the outer cylinder. A second drive component is arranged at the bottom of the support platform to drive the support platform to move up and down. A steam component is also arranged inside the casing to provide high-temperature steam to the inside of the inner cylinder.

[0007] The steam assembly provides high-temperature steam to the inner cylinder, helping to sterilize the waste inside. When the two heat-sealing blades approach and abut each other, the bottom of the sealing film is heat-sealed first, sealing the bottom of the cylindrical sealing film. Then, the support platform moves upward to abut the bottom of the outer cylinder, providing support for the bottom of the sealing film and preventing the sealing film stacked on the outer wall of the inner cylinder from moving downward after the waste is dropped into the inner cylinder. After the experiment is completed, the laboratory personnel open the end cap and drop the waste into the inner cylinder. Then, the steam assembly delivers high-temperature steam into the inner cylinder. By setting the high-temperature sterilization time, after the high-temperature sterilization is completed, the support platform moves downward, and the waste moves downward with the support platform. The stacked sealing film on the outer wall of the inner cylinder is pulled downward by the waste and unfolds. Then, the heat-sealing blades approach each other and heat-seal the sealing film again on the top of the waste. At this time, the waste is sealed and packaged inside the sealing film, realizing automatic waste packaging without manual contact with the waste and preventing the sterilized waste from being exposed to the outside air again, which could cause bacterial growth.

[0008] The hot wire is then cut off to start heating, melting the area to be sealed by the heat-sealing knife. This separates the packaged waste from the upper packaging film while ensuring the bottom of the packaging film remains sealed for future disinfection of the waste. No equipment readjustment is required, ensuring ease of use.

[0009] Preferably, the steam assembly includes a steam generating chamber located inside the housing, an electric heating plate inside the steam generating chamber, a nozzle inside the steam generating chamber, a water storage chamber inside the housing for storing water, the nozzle communicating with the water storage chamber, a top cover on the end cap, the bottom of the top cover fitting against a support ring when the end cap is closed, a first flexible hose connecting the top cover and the steam generating chamber, the first flexible hose connecting the top cover and the top of the steam generating chamber, a waste liquid recovery chamber inside the housing, an annular reflux groove inside the lower side of the top cover, a second flexible hose connecting the top cover and the waste liquid recovery chamber, the connection port of the second flexible hose and the top cover located in the reflux groove.

[0010] The electric heating plate heats up when powered on, and the nozzle sprays water onto the electric heating plate to form steam. This method of generating steam is faster and eliminates the need to heat the entire water storage chamber at once, which helps save energy and also helps to improve the speed of disinfection.

[0011] Preferably, a positioning groove is provided on the top surface of the outer cylinder, a positioning pin is provided at the bottom of the support ring, a guide tube is provided on the inner side of the inner cylinder, and a connecting pipe that matches the guide tube is provided on the top cover. The first flexible tube is connected to the connecting pipe, and when the end cap is closed, the bottom of the connecting pipe abuts against the top of the guide tube.

[0012] Because high-temperature steam rises, the guide pipe and connecting pipe design direct the steam downwards into the inner cylinder, allowing it to come into greater contact with the waste. This prevents a large amount of steam from rising towards the top of the hood without contacting the waste, thus avoiding energy waste. It also helps improve the speed and effectiveness of disinfection.

[0013] Preferably, an annular conveying pipe is provided on the lower side of the inner cylinder, the conveying pipe is connected to the bottom of the guide pipe, and multiple air vents are evenly opened on the conveying pipe.

[0014] The delivery pipe allows steam to be discharged evenly in a ring along the inner wall of the inner cylinder, which helps the steam to come into more uniform contact with the waste and further improves the steam sterilization effect.

[0015] Preferably, the ring has two grooves, and the hooks are slidably disposed in the two grooves respectively. The lower end of the hook extends from the bottom of the ring below the groove. A spring is disposed inside each groove to keep the hook pushed upward. A battery is also disposed on the ring. A trigger button is disposed inside one of the grooves and is electrically connected to the battery. A buzzer is disposed at the bottom of the ring and is electrically connected to the trigger button and the battery.

[0016] As the platform moves downwards, the sealing film underneath is heat-sealed by the heat-sealing knife, keeping it closed. Therefore, waste inside the inner cylinder pulls the sealing film, which is fitted onto the outer wall of the inner cylinder, downwards along with the platform. When the sealing film is not long enough, it pulls down on the hook. Pressing the trigger button after the hook is pulled down will cause a buzzer to sound, alerting laboratory personnel that the sealing film is not long enough for timely replacement. This helps ensure stable equipment operation and improves the equipment's intelligence and convenience.

[0017] Preferably, a fan is provided inside the steam generating chamber, the fan is used to blow steam toward the top of the steam generating chamber, and the nozzle is located between the electric heating plate and the fan.

[0018] The fan can quickly deliver high-temperature steam into the inner cylinder, increasing the speed of waste disinfection. Simultaneously, after steam disinfection is complete, the fan can blow hot air from inside the steam generation chamber into the inner cylinder, helping to quickly dry the damp waste and ensuring it is as dry as possible before packaging, further preventing bacterial growth.

[0019] Preferably, a drawer is slidably provided on the lower side of the housing, and the second drive assembly includes a first electric push rod and a second electric push rod. The first electric push rod and the second electric push rod are both vertically fixedly installed at the bottom of the sterilization chamber. The output ends of the first electric push rod and the second electric push rod are both hinged to the bottom of the tray. The first electric push rod and the second electric push rod are arranged side by side with a gap between them. The first electric push rod is located on the side closer to the drawer, and the second electric push rod is located on the side away from the drawer.

[0020] The drawer is designed to store sterilized and packaged waste, making it easy for laboratory personnel to remove the waste from inside the machine. At the same time, the first and second electric push rods can be controlled to tilt the tray towards the drawer, allowing the sterilized and packaged waste to fall into the drawer automatically, preventing the packaged waste from remaining on the tray for a long time and affecting the next waste sterilization.

[0021] Preferably, the bottom of the top cover is provided with an annular rubber ring. The rubber ring can improve the contact sealing between the top cover and the support ring, prevent steam from overflowing into the sterilization chamber outside the inner cylinder when it is conveyed to the inner cylinder, prevent the sterilization chamber from being damp and breeding bacteria, and further ensure the hygiene of the equipment.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The solid waste sterilization and reduction integrated treatment device designed in this invention sets up an inner cylinder and an outer cylinder inside the sterilization chamber, and also sets up a sealing film and a heat sealing knife. The bottom of the sealing film is first heat-sealed by the heat sealing knife, and after the waste is sterilized inside the inner cylinder, the top of the sealing film is heat-sealed by the heat sealing knife. The sterilized waste is automatically sealed and packaged, eliminating the need for manual packaging, and preventing the sterilized waste from coming into contact with the outside air again, further reducing safety hazards.

[0023] 2. The solid waste sterilization and reduction integrated treatment device designed in this invention is also equipped with hooks, batteries, trigger buttons and buzzers. It can automatically detect whether the sealing film is used up by the waste pulling the sealing film when the tray moves down. If the sealing film is used up, the buzzer can remind laboratory personnel to replace it in time, ensuring that the equipment can effectively automatically pack the waste, improving the intelligence level and ease of use of the equipment.

[0024] 3. The solid waste sterilization and volume reduction integrated treatment device designed in this invention is further equipped with a guide pipe and a connecting pipe. The guide pipe and connecting pipe allow steam to be delivered to the bottom of the inner cylinder, preventing steam from flowing only upwards and failing to effectively sterilize the waste at the bottom of the inner cylinder at high temperature, thus ensuring the sterilization effect. At the same time, an annular conveying pipe is also provided to allow steam to be evenly released from the bottom of the inner cylinder. Attached Figure Description

The inner cylinder 6 and the outer cylinder 4 are concentrically spaced. A positioning groove 25 is provided on the top surface of the outer cylinder 4, and a positioning pin 26 is provided at the bottom of the support ring 7 corresponding to the positioning groove 25.

[0028] refer to Figure 2 and Figure 7 A guide pipe 27 is provided on the inner side of the inner cylinder 6, and an annular conveying pipe 29 is provided on the lower inner side of the inner cylinder 6. The bottom of the conveying pipe 29 is connected to the guide pipe 27, and multiple ventilation holes 37 are evenly opened on the conveying pipe 29.

[0029] refer to Figure 2 , Figure 3 and Figure 4Two grooves 38 are formed on the side of the ring 7 near the inner cylinder 6, and the two grooves 38 are symmetrically arranged about the axis of the inner cylinder 6. A hook 8 is provided inside each groove 38. The hook 8 is slidably disposed inside the two grooves 38, and the lower end of the hook 8 extends out from the bottom of the ring 7 below the groove 38.

A trigger button 32 is provided inside one of the grooves 38 and is electrically connected to the battery 31. A buzzer 33 is also provided at the bottom of the ring 7 and is electrically connected to the trigger button 32 and the battery 31.

[0030] refer to Figure 2 , Figure 3 , Figure 4 as well as Figure 7 A cylindrical sealing film 9 is sleeved on the outer side of the inner cylinder 6. The sealing film 9 is integrally and continuously stacked along the axial direction of the inner cylinder 6. The sealing film 9 is located between the outer cylinder 4 and the inner cylinder 6. Two hooks 8 simultaneously hook the top of the sealing film 9. Two heat sealing knives 10 are symmetrically arranged below the outer cylinder 4. One heat sealing knife 10 is provided with a cutting hot wire 11, and the other heat sealing knife 10 is provided with a cutting groove 12 corresponding to the cutting hot wire 11. Inside the sterilization chamber 3, two first drive components 13 are provided corresponding to the two heat sealing knives 10. In this invention, the first drive component 13 is an electric lead screw nut. The first drive component 13 is used to drive the heat sealing knife 10 to move horizontally. A support platform 14 is provided below the outer cylinder 4. A second drive component 15 is provided at the bottom of the support platform 14 to drive the support platform 14 to move up and down.

[0031] refer to Figure 2 The casing 1 also houses a steam assembly for supplying high-temperature steam to the inner cylinder 6. The steam assembly includes a steam generating chamber 16 located inside the casing 1, an electric heating plate 17 inside the steam generating chamber 16, and a fan 34 located above the electric heating plate 17. The fan 34 blows steam towards the top of the steam generating chamber 16. A nozzle 18 is located inside the steam generating chamber 16, positioned between the electric heating plate 17 and the fan 34, pointing downwards towards the electric heating plate 17. A water storage chamber 19 is located inside the casing 1, and the nozzle 18 communicates with the water storage chamber 19. A top cover 20 is provided on the end cover 2. The top cover 20 is cylindrical, with the same diameter as the inner cylinder 6, and its top is arc-shaped. An annular rubber ring 36 is fixedly installed at the bottom of the top cover 20. When the end cap 2 is closed, the bottom of the top cover 20 abuts against the top of the support ring 7.

[0032] refer to Figure 2 and Figure 3The top cover 20 is equipped with a connecting pipe 28 that matches the guide pipe 27, and the bottom of the connecting pipe 28 is flush with the bottom of the top cover 20. An annular return groove 23 is provided on the lower side inside the top cover 20. A first flexible hose 21 connects the top cover 20 and the steam generating chamber 16, and the first flexible hose 21 connects the connecting pipe 28 inside the top cover 20 to the top of the steam generating chamber 16. A waste liquid recovery chamber 22 is also provided inside the housing 1, and a second flexible hose 24 connects the top cover 20 and the waste liquid recovery chamber 22. The connection port of the second flexible hose 24 to the top cover 20 is located within the return groove 23. With the positioning groove 25 and the positioning pin 26 in place, when the end cover 2 is closed, the bottom of the connecting pipe 28 abuts against the top of the guide pipe 27.

[0033] In addition, refer to Figure 2 The steam generating chamber 16 is located at the top, the water storage chamber 19 is located in the middle, and the waste liquid recovery chamber 22 is located at the bottom. This ensures that the steam generated by the steam generating chamber 16 does not come into contact with the water storage chamber 19 or the waste liquid recovery chamber 22.

[0034] refer to Figure 1 A drawer 35 is slidably provided on the lower side of the casing 1. The second drive assembly 15 includes a first electric push rod 1501 and a second electric push rod 1502. The first electric push rod 1501 and the second electric push rod 1502 are both vertically fixedly installed at the bottom of the sterilization chamber 3. The output ends of the first electric push rod 1501 and the second electric push rod 1502 are hinged to the bottom of the tray 14. The first electric push rod 1501 and the second electric push rod 1502 are arranged side by side with intervals. The first electric push rod 1501 is located on the side closer to the drawer 35, and the second electric push rod 1502 is located on the side away from the drawer 35.

[0035] Before use, refer to Figures 1 to 5 as well as Figure 7The user can rotate and open end cap 2 to remove the inner cylinder 6 vertically upwards along its axis. The cylindrical encapsulation film 9 is then placed from bottom to top on the outer wall of the inner cylinder 6, stacking the encapsulation film 9 as much as possible along its axis. The top of the encapsulation film 9 is then hooked onto the two hooks 8 of the inner cylinder 6. After installation, a portion of the bottom of the encapsulation film 9 is left exposed, with the exposed portion being longer than the radius of the inner cylinder 6. The battery 31 is then installed at the bottom of the support ring 7. The inner cylinder 6 is then reinserted into the outer cylinder 4. When reinserting the inner cylinder 6, it is necessary to ensure that the two positioning pins 26 on the support ring 7 are engaged in the two positioning slots 25, and that the side of the inner cylinder 6 with the guide tube 27 faces the water storage chamber 19. The device is then started, and the second drive assembly 15 controls the platform 14 to move horizontally downwards to avoid obstacles. The two first drive components 13 drive the two heat sealing blades 10 to move closer together, clamping the encapsulation film 9. Simultaneously, the heat sealing blades 10 heat up to 110 degrees Celsius for 2 seconds, then stop heating. The cutting wire 11 then heats up to 200 degrees Celsius for 2 seconds, cutting off any excess encapsulation film 9 below. The cutting wire 11 then stops heating. Afterwards, the two first drive components 13 control the two heat sealing blades 10 to reset, and the support platform 14 resets. At this point, the bottom of the encapsulation film 9 is heat-sealed, and the preparation work is complete.

[0036] When using, refer to Figure 2 The user rotates to open end cap 2 and discards experimental waste into the inner cylinder 6. At this time, the support platform 14, supporting the waste from the bottom of the sealing film 9, enters the inner cylinder 6 without pulling on the sealing film 9. The user then closes end cap 2. When end cap 2 is closed, the top cover 20 on end cap 2 abuts against the support ring 7 on the inner cylinder 6, and the connecting tube 28 aligns and abuts against the guide tube 27. The equipment is then started to sterilize the waste with high-temperature steam.

[0037] During disinfection, the electric heating plate 17 rapidly heats up, and the nozzle 18 draws water from the water storage chamber 19 and sprays it onto the electric heating plate 17. Upon contact with the water, the electric heating plate 17 heats and evaporates the water, forming steam. The fan 34 blows the steam upwards, preventing it from contacting the water sprayed from the nozzle 18, directing the steam towards the first flexible hose 21. The high-temperature steam enters the first flexible hose 21 and then flows through it into the connecting pipe 28 at the top cover 20. Subsequently, driven by the airflow from the fan 34, the high-temperature steam travels along the connecting pipe 28 into the guide pipe 27, continuing its movement towards the lower side of the inner cylinder 6. Finally, the high-temperature steam enters the annular conveying pipe 29 at the bottom of the inner cylinder 6, and then passes through multiple vents 37 on the conveying pipe 29 to fully contact the waste, thus disinfecting it at high temperature.

[0038] When sterilizing at high temperatures, refer to Figure 2The support platform 14 presses the sealing film 9 against the bottom of the outer cylinder 4 from below, and the top cover 20 is also sealed against the support ring 7, so that high-temperature steam will not leak to the outside of the inner cylinder 6.

[0039] At the same time, refer to Figure 2 Excess water vapor will rise and come into contact with the top of the top cover 20. The water vapor will gather into water droplets on the top cover 20 and flow down along the inner wall of the top cover 20 into the return tank 23. Finally, it will be recycled into the waste liquid recovery chamber 22 through the second hose 24 connected to the return tank 23 to complete the recycling.

[0040] After the high-temperature steam sterilization is complete, nozzle 18 stops spraying water onto the electric heating plate 17, but the electric heating plate 17 continues to heat, and fan 34 continues to operate. After the electric heating plate 17 has evaporated all the water vapor, it begins to heat the air inside the steam generating chamber 16. Fan 34 blows this hot air towards the inner cylinder 6, allowing the water droplets condensed inside the inner cylinder 6 to evaporate as much as possible, keeping the inner cylinder 6 and the waste dry. At this time, to monitor the humidity inside the inner cylinder 6, a hygrometer can be installed inside the inner cylinder 6. Once the hygrometer reading reaches the set value, the operation of the electric heating plate 17 and fan 34 is stopped. At this point, the sterilization process is completely finished.

[0041] Afterwards, refer to Figures 2 to 7 The equipment begins packaging the disinfected waste. The second drive assembly 15 moves the platform 14 horizontally downwards. Because the waste presses the bottom of the sealed packaging film 9 onto the platform 14, the platform 14 stretches and expands the packaging film 9 stacked on the outer wall of the inner cylinder 6 as it moves downwards. The platform 14 stops moving after reaching the set position. Then, the two first drive assemblies 13 drive the two heat-sealing blades 10 to approach the outer cylinder 4 from both sides towards its axis. The two heat-sealing blades 10 clamp the packaging film 9 from both sides, and simultaneously heat the two heat-sealing blades 10 to 110 degrees Celsius for 2 seconds. Afterwards, the heat-sealing blades 10 stop heating, and the packaging film 9 is re-heat-sealed from the top of the waste. At this point, the waste packaging is complete. Next, the cutting wire 11 heats up to 200 degrees Celsius for 2 seconds. Since the cutting wire 11 is located in the middle of the heat-sealing blade 10, it will cut off the encapsulation film 9 in the middle of the heat-sealing position. At the same time, the upper and lower encapsulation films 9 are both in a heat-sealed bonded state after being cut off. The packaged waste is then separated from the upper encapsulation film 9.

[0042] Then, the first drive assembly 13 drives the heat sealing knife 10 to reset. The first electric push rod 1501 of the second drive assembly 15 continues to retract downward. As the first electric push rod 1501 retracts downward, the height of the second electric push rod 1502 is higher than the height of the first electric push rod 1501. Therefore, the tray 14 begins to tilt in the direction of the first electric push rod 1501. The packaged waste will slide down the tilted tray 14 into the drawer 35 and be collected.

[0043] Finally, the first electric push rod 1501 returns to being flush with the second electric push rod 1502, and the support platform 14 returns to a horizontal state. Then, the first electric push rod 1501 and the second electric push rod 1502 simultaneously drive the horizontal support platform 14 to move upward, so that the support platform 14 returns to its original position and is in contact with the bottom of the outer cylinder 4.

[0044] During use, if the length of the encapsulation film 9 is insufficient, as the tray 14 moves downwards, the waste pressing against the bottom of the encapsulation film 9 will move along with the tray 14, pulling the encapsulation film 9 downwards. When the encapsulation film 9 is insufficient, it will pull the hook 8 connected to the top of the encapsulation film 9. The hook 8, pulled downwards, will contact the trigger button 32, which will then control the buzzer 33 to sound, reminding the user that the encapsulation film 9 is insufficient and allowing the user to replace it in time.

[0045] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
