Description

Technical Field

[0001] The present invention relates to medical waste treatment technology, and particularly to an integrated cabin for medical waste treatment. Background Art

[0002] Medical waste includes infectious, injurious, and pathological medical waste, epidemic-related waste generated by quarantine institutions, and waste generated at airports and ports that requires disinfection and sterilization. Due to the infectivity and harmfulness of medical waste, the compliance disinfection and sterilization of medical waste, as well as reducing the impact of secondary pollution during the disinfection and sterilization process on on-site operators and the surrounding environment, are issues that the whole society is concerned about and striving to solve.

[0003] After years of development, medical waste treatment technology has made significant progress in controlling secondary pollution and protecting on-site workers. In particular, the application of the automatic transmission line in centralized medical waste treatment plants has realized the unmanned operation of a large amount of handling work inside the medical waste treatment plant, greatly reducing the work intensity of on-site operators and the infection risk of on-site operators.

[0004] However, due to still existing technical obstacles, in centralized treatment plants, some links still require manual operation. Especially in the storage area of medical waste, after the medical waste is unloaded from the transfer vehicle and transported to the feeding temporary storage area, and the medical waste that cannot be processed in time is transported to the cold storage and then transported from the cold storage to the feeding temporary storage area, etc., still rely on manual operation. In this case, the operators still need to enter the site and be exposed to the same space as the medical waste to be treated. The germs in the medical waste and the malodorous steam leaked during the treatment process (especially the non-incineration treatment process) inevitably fill the air at the site, and the harm to the on-site production operators is inevitable. Moreover, since there are operators working in the production area, in order to promote the air circulation and the entry of fresh air in the workshop, the production area not only does not adopt a closed design, but usually has a tall and spacious space design. The germ-carrying air and malodor at the production site will inevitably overflow from the workshop to the factory area and affect the surrounding environment. This is also the main reason for the "neighborhood avoidance effect" near medical waste treatment plants and the requirement in the relevant technical specifications of centralized medical waste treatment plants that the treatment plant must maintain a distance from the surrounding residential areas.

[0005] Therefore, the impact of the overflow of germ-carrying air and malodor during the treatment process of medical waste treatment plants on the surrounding environment, as well as the infection risk and occupational health problems of on-site operators, have become two major pain points of medical waste treatment plants. Moreover, various non-compliant operations caused by human factors in medical waste treatment plants objectively make it difficult to continuously meet environmental protection indicators and difficult to control non-compliant phenomena during the treatment process.

[0006] CN114715586A discloses a temporary storage for medical waste turnover boxes, a method for loading and unloading the temporary storage, and a medical waste treatment system. The temporary storage for medical waste turnover boxes includes an unloading device and a temporary storage device, and also includes a first transfer device, a second transfer device, and P transfer pallets. The temporary storage device includes N temporary storage conveyor lines arranged in sequence along the left and right directions. The first transfer device includes a first transverse guide rail, a first transfer platform, and a second transfer platform. The second transfer device includes a second transverse guide rail, a third transfer platform, and a fourth transfer platform. The unloading device can transfer medical waste turnover boxes. The temporary storage for medical waste turnover boxes can be automatically stored, and the device construction cost is low and the working energy consumption is low. The invention also discloses a method for loading and unloading the temporary storage, with a reasonable material route, smooth and efficient operation. The invention also discloses a medical waste treatment system, in which the workers are not required to directly contact the medical waste and turnover boxes that have not been disinfected and sterilized during transportation, temporary storage, circulation, disinfection, and crushing, thereby reducing labor costs. Undoubtedly, the technical solution disclosed in the above patent document is a beneficial attempt in the relevant technical field. Summary of the invention

[0038] The beneficial effects of the present invention are as follows:

[0039] 1. By means of unmanned operation in the bacterium-carrying area and the malodorous gas area at the medical waste treatment site, and by arranging the storage module and the medical waste treatment module in the negative pressure enclosed cabin, the present invention can effectively prevent the bacterium-carrying air and malodor from overflowing during the temporary storage, handling, disinfection and sterilization, and crushing of medical waste, which may affect the on-site operators and the surrounding environment. At the same time, the ventilation system can collect the air inside the negative pressure enclosed cabin and discharge it to the waste gas treatment system, so as to maintain the negative pressure inside the negative pressure enclosed cabin. The waste gas treatment system disinfects and deodorizes the air by means of activated carbon adsorption or biological purification and then discharges it externally, which can further prevent the bacterium-carrying air and malodor from overflowing.

[0040] 2. By arranging the ventilation system, the waste gas treatment system, the auxiliary module, the sewage treatment system, the centralized control system, the on-line monitoring system and the remote management system in the non-negative pressure non-enclosed cabin, and by reasonably arranging the positions of the automatic temporary storage warehouse for medical waste, the handling device for the turnover container to leave the warehouse, the disinfection and sterilization unit for the empty turnover container, the loading and feeding unit, the automatic handling device for the turnover container and the automatic handling device for the empty turnover container, the structure of the storage module is compact, the occupied space is greatly reduced, the volume inside the negative pressure enclosed cabin can be reduced, the difficulty of enclosing the negative pressure enclosed cabin and maintaining the negative pressure environment can be reduced, and the energy consumption of the ventilation system and the waste gas treatment system can be reduced, thereby reducing the construction and operation costs.

[0041] 3. By closing the turnover container entrance and exit when the turnover container does not need to enter and exit and when loading the turnover container on the loading and feeding unit, and by closing the waste residue outlet when the waste residue does not need to be discharged, the present invention can further ensure the negative pressure state inside the negative pressure enclosed cabin and prevent the bacterium-carrying air and malodor from overflowing. The ventilation system is connected to the ventilation opening through a fan, and the fan can collect the bacterium-carrying air and the leaked malodorous steam inside the negative pressure enclosed cabin and discharge them to the waste gas treatment system. The waste gas treatment system disinfects and deodorizes the air by means of activated carbon adsorption or biological purification and then discharges it externally. At the same time, the ventilation system can also send fresh air into the negative pressure enclosed cabin. Since there are very few external connection ports for the negative pressure enclosed cabin, the fan only needs a very small power to ensure the negative pressure state inside the negative pressure enclosed cabin.

[0042] 4. The present invention integrates and skids various equipment and supporting pipelines and lines of the integrated medical waste treatment cabin on different sub-bases, so that the equipment skid-mounted on the sub-base can be hoisted and transported as a whole together with the sub-base. After one-time manufacturing in the factory, the sub-base with the equipment, pipelines and circuits is transported to the site. Multiple sub-bases form the cabin base, which makes the manufacturing of the integrated medical waste treatment cabin simple and greatly reduces the time for on-site work.

The medical waste automatic temporary storage warehouse 13 becomes a cold storage with the function of temperature regulation. A temperature sensor is arranged in the cold storage, and a position sensor is arranged at each storage position on multiple medical waste automatic temporary storage conveying lines 131 inside the cold storage. When a turnover container is put into storage at a storage position, it sends a signal to the centralized control system 7. The centralized control system 7 automatically records the storage time and starts timing.

[0102] The working process of the medical waste treatment module 2 is as follows:

[0103] B1. The third conveying platform 142 of the turnover container outbound handling device 14 conveys the turnover container 11 containing medical waste to the feeding position of the automatic loading device 26. The automatic loading device 26 lifts and turns over the medical waste in the turnover container 11 and pours it into the sterilization trolley 22 on the feeding platform 234, and places the empty turnover container after pouring back onto the turnover container outbound handling device 14;

[0104] B2. The feeding platform 234 transports the sterilization trolley 22 containing medical waste to the feeding and discharging ferry platform 231;

[0105] B3. The feeding and discharging ferry platform 231 pushes the sterilization trolley 22 containing medical waste into the disinfection and sterilization equipment 21. After disinfection and sterilization, the feeding and discharging ferry platform 231 pulls out the sterilization trolley 22 from the disinfection and sterilization equipment 21, and then transfers the sterilization trolley 22 pulled out from the disinfection and sterilization equipment 21 onto the fourth conveying platform 232;

[0106] B4. The fourth conveying platform 232 conveys the sterilization trolley 22 pulled out from the disinfection and sterilization equipment 21 onto the crushing ferry platform 233;

[0107] B5. The elevator 24 can lift and flip the sterilization trolley 22 and pour the materials in the sterilization trolley 22 into the crusher 25, and then transport the sterilization trolley 22 to the crushing and ferrying platform 233. The crusher 25 crushes and destroys the sterilized medical waste and discharges the waste residue from the waste residue outlet into the negative pressure closed cabin 101;

[0108] B6. The crushing and ferrying platform 233 transports the empty sterilization cart 22 to the material preparation platform 234, ready to receive the medical waste dumped by the automatic loading device 26.

[0109] In this embodiment, the negative pressure closed cabin 101 is provided with a turnover container entrance and exit, a waste residue outlet and a ventilation port. The turnover container entrance and exit and the waste residue outlet are both provided with openable and closable covers. The turnover container entrance and exit correspond to the position of the loading and feeding unit 17, the waste residue outlet corresponds to the position of the crusher 25 of the medical waste treatment module 2, and the ventilation port is connected to the ventilation system 4.

[0110] The inlet and outlet of the turnover container and the outlet of the waste residue are both provided with an openable and closable cover plate. When the turnover container 11 is not required to enter or exit and when the turnover container 11 on the loading and feeding unit 17 is not required to be loaded, the inlet and outlet of the turnover container are closed, and when the waste residue is not required to be discharged, the outlet of the waste residue is closed, which can further ensure the negative pressure state in the negative pressure closed cabin 101 and prevent the overflow of the contaminated air and malodor; the ventilation system 4 is connected to the vent through an induced draft fan, and the induced draft fan can collect the contaminated air and the leaked malodorous steam in the negative pressure closed cabin 101 and discharge them to the exhaust gas treatment system 6, and the exhaust gas treatment system 6 disinfects and deodorizes the air through activated carbon adsorption or biological purification, and then discharges it to the outside. At the same time, the ventilation system 4 can also send fresh air into the negative pressure closed cabin 101. Since the negative pressure closed cabin 101 has few external connection ports, the induced draft fan only needs a small power to ensure the negative pressure state in the negative pressure closed cabin 101.

[0111] In this embodiment, the shelter base 103 includes a plurality of sub-bases 1031 that can be connected into a whole, and various devices of the integrated medical waste treatment shelter and the supporting pipelines and lines are integrated and skid-mounted on different sub-bases 1031. In this embodiment, the negative pressure closed cabin 101 and the non-negative pressure non-closed cabin 102 both include a roof and a plurality of wall panels arranged on the lower side of the roof, and the lower sides of the plurality of wall panels are connected to the shelter base 103.

[0112] like Figures 4 - 6 As shown, in this embodiment, a quick-connect device 104 is provided between every two adjacent sub-bases 1031 of the cabin base 103 to facilitate the positioning and connection of each module. The quick-connect device 104 includes a guide seat 1041, a positioning seat 1042, a locking pin 1043, a washer 1044 and a locking nut 1045.

[0113] The guiding seat 1041 is connected to one of the two adjacent sub-bases 1031, and the positioning seat 1042 is connected to the other sub-base 1031 of the two sub-bases 1031. There is a guiding groove 10411 on the guiding seat 1041, and a guiding block 10421 on the positioning seat 1042. A through hole is opened on the guiding block 10421, and the locking pin 1043 can pass through the hole. When connecting, the guiding block 10421 is inserted into the guiding groove 10411 to position the two connected sub-bases 1031 in one direction.

[0114] One end of the locking pin 1043 has a positioning step and the other end has a thread. The size of the positioning step is larger than the opening size of the guiding groove 10411 on the guiding seat 1041. After the positioning seat 1042 is inserted into the guiding seat 1041, a washer 1044 is sleeved on the guiding block 10421. The locking pin 1043 is inserted into the hole on the guiding block 10421 from the guiding seat 1041 end and then passes out from the positioning seat 1042 end. The locking nut 1045 is tightened, and the two sub-bases 1031 are pulled together and fixed to position the two connected sub-bases 1031 in one direction.

[0115] As Figures 7 - 10 shown, in this embodiment, a hoisting device 105 is provided on each sub-base 1031 of the cabin base 103, including a hollow sleeve 1051 and a sling connection pin 1052. The hoisting device 105 is arranged on the outer main beam 10311 of the sub-base 1031, and multiple groups are arranged at a certain interval. Every two opposite hoisting devices 105 on the left and right sides form a group, and every two groups form a hoisting position 105. Selecting different two groups of hoisting devices 105 can form multiple hoisting schemes.

[0116] The hollow sleeve 1051 passes through the opening on the outer main beam 10311 of the sub-base 1031 and is welded to the outer main beam 10311. A section of internal thread 10511 is provided inside the hollow sleeve 1051. The sling connection pin 1052 is a pin with a limit step 10522 at one end and an external thread 10521 at the other end. During hoisting, the sling connection pin 1052 is inserted into the hole on the sling and then into the hollow sleeve 1051. The connection pin 1052 is rotated so that the external thread 10521 on the connection pin 1052 cooperates with the internal thread 10511 of the hollow sleeve 1051 and is tightened. During hoisting, the connection pin 1052 and the sling are effectively limited and will not fall off, ensuring safety.
