Description

Technical Field

[0001] The present invention mainly relates to the technical field related to the treatment of medical turnover boxes, and in particular to a medical waste turnover box and a box cover disinfection and cleaning machine. Background Art

[0002] Medical waste turnover boxes and box covers are plastic turnover boxes and lids for storing medical waste. Existing regulations require that medical waste generated by hospitals must be sealed and placed in turnover boxes with lids, and then these turnover boxes are uniformly taken to centralized processing points for medical waste treatment. Hospitals are not allowed to process medical waste for the time being; after the centralized processing point dumps the medical waste (manually or automatically), the turnover boxes and box covers containing the medical waste need to be disinfected and cleaned, and then taken back to the hospital for recycling.

[0003] There are reinforcing ribs at the bottom of the turnover box and a circle of reinforcing ribs on the outer edge of the turnover box mouth. When the turnover box mouth is turned down for cleaning, there will be water on the bottom and the back of the outer edge of the turnover box mouth. The fan cannot completely remove the water. Therefore, the turnover box mouth is selected to be horizontal for cleaning, that is, there will be no place for water on the turnover box. In the existing related technologies, such as the related technology of a cleaning machine for medical waste turnover boxes and box covers, which was previously applied by our company with the publication number CN217342724U, the turnover box mouth is cleaned by facing the horizontal direction.

[0004] The turnover boxes and box covers can be placed directly in the cleaning machine manually, or they can enter the cleaning machine through an automatic conveyor track. When the automatic conveyor track structure is used, the turnover box opening is facing upward when it is conveyed on the track after automatic unloading. Before entering the cleaning machine, a 90-degree flipping machine is required to flip the turnover box 90 degrees, that is, the opening is facing horizontal, and then enter the cleaning machine; the 90-degree flipping machine or automatic conveyor track in front of the cleaning machine generally uses rollers to convey inclined turnover boxes. Since the cleaning machine is not suitable for the above conveying methods, the connection between the two conveying methods when entering and exiting the cleaning machine often becomes stuck, requiring manual intervention; and before entering the cleaning machine, the box opening on the track is not completely horizontal (such as the aforementioned turnover box opening has reinforcing ribs, so that when the turnover box opening is horizontal, the heights on both sides are different), there is a certain angle, so that water will accumulate at the reinforcing ribs of the turnover box. The most ideal cleaning state is that the box opening is set horizontally. However, when the turnover box enters the cleaning machine from the previous station, the turnover box needs to be flipped at a certain small angle to change its opening tilted state to a completely horizontal state, which will also cause the turnover box to jam during operation.

[0005] In the prior art, (the above publication number is CN217342724U, and the name is a cleaning machine for medical waste turnover boxes and box covers), the water tank can be used for disinfection and flushing of the turnover box, and the water tank has only one layer of filter screen, the filtering accuracy is not enough, and the pump and nozzle are easily blocked by the dirt washed down. In the prior art, the cleaning of the turnover box and the box cover adopts a parallel double station, and the two sides of the turnover box are placed on the conveyor chain and the conveyor roller respectively. The conveying structures on both sides are different, which makes the movement of the turnover box not flexible enough during transportation, and the parallel double station structure design makes the cleaning machine occupy a large space in the width direction, and the layout is not compact and reasonable. Summary of the invention

[0006] In order to solve the deficiencies of the current technology, the present invention combines the existing technology and, based on practical applications, provides a medical waste turnover box and box cover disinfection and cleaning machine, which has the advantages of compact overall structure, small space occupation, and can realize the disinfection and cleaning of turnover boxes and box covers.

This structural design greatly reduces the space occupied by the equipment in the width direction. The guide rod on the upper part can not only be used as a guide for the box cover, but also can limit the upper part of the turnover box to prevent the turnover box from accidentally resting on the push plate and interfering with the upper nozzle, causing damage to the nozzle.

[0027] 3. The overall structural layout design of the chain push plate conveying assembly of the present invention is reasonable and compact. The chain push plate is supported both above and below when in operation, which improves the stability during operation and the service life of the equipment. The unique roller tensioning assembly structural design can make it easy to tighten the roller chain in a small space.

[0028] 4. The disinfection and cleaning pipeline of the present invention adopts a double-layer filtering structure with high filtering accuracy, avoiding the problem of easy clogging of the nozzle and the pump.

[0048] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the application.

[0049] This embodiment provides a medical waste turnover box and box cover disinfection and cleaning machine, which is mainly used for disinfecting and cleaning the turnover boxes and box covers used for medical waste.

[0050] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the main structure of the disinfection and cleaning machine of the present application includes: a machine body 3, a disinfection and cleaning pipeline system 4, an inlet roller conveyor assembly 5, a chain push plate conveyor assembly 7, a turnover box alignment and reset assembly 8, a box cover guide assembly 6 and an outlet roller conveyor assembly 9.

[0051] For the turnover box 1 and the box cover 2 used for medical waste, the cleaning process is mainly divided into two steps: high-pressure disinfectant spraying and high-pressure water flushing. The whole process adopts full automation control, which can not only thoroughly disinfect the medical waste turnover box and the box cover, but also effectively reduce the labor intensity and save labor costs. In the fully automated control process, the turnover box 1 that needs to be cleaned enters the entrance roller conveyor assembly 5 through the previous station (the previous station is generally a flip machine, which mainly flips the turnover box 1 90° so that its original opening facing the upper part is turned to a horizontal state with an opening facing the upper part), enters the machine body 3 through the connection of the entrance roller conveyor assembly 5, and is mainly transported backwards by the chain push plate conveyor assembly 7 after entering the machine body, so that it passes through the disinfection spray system and the water flushing spray system of the disinfection and cleaning pipeline system 4 in turn, and finally is sent out of the machine body 3 through the exit track conveyor assembly 9. When the box cover 2 is disinfected and cleaned, the box cover 2 is transported by the chain push plate conveying assembly 7, guided by the box cover guide assembly 6, and sequentially passes through the disinfection spray system of the disinfection and cleaning pipeline system 4 and the clean water flushing spray system to achieve the disinfection and cleaning operation of the box cover 2.

[0052] In this application, the cleaning machine is made of high-quality stainless steel materials, which not only improves the corrosion resistance of the whole machine, but also ensures the strength and rigidity of the cleaning machine structure, and also makes the appearance of the whole machine beautiful and generous. The cleaning machine frame is made of high-quality stainless steel profiles and stainless steel plates welded and processed. The structure is simple and light, and it has sufficient strength and rigidity to support heavier components such as water tanks and water pumps. The middle baffle is welded in the center of the bottom plate of the cleaning machine, which effectively isolates the disinfection and flushing area from the clean water flushing area; the supporting foot adopts a disc with a hole and a threaded adjustable structure, and the height of the foot is controlled by the tightness of two bolts to adapt to the uneven floor of the factory; the guard plates at the inlet and outlet of the cleaning machine are threaded for easy disassembly and maintenance. Because the turnover box will drop the medical waste remaining on the turnover box during cleaning, in order to clean up the medical waste inside the cleaning machine in a timely and simple manner, there are five side doors on both sides of the cleaning machine (the side doors are hidden in the figure), and the side doors are fixed on the cleaning machine using duckbill buckles that are easy to disassemble, and the side doors can be disassembled and installed by one person barehanded.

[0053] In the present application, in order to avoid the problem of the turnover box 1 being stuck and requiring manual assistance when entering the cleaning machine from the turning machine, the present application sets an entrance roller conveyor assembly 5 at the head end of the cleaning machine. The entrance roller conveyor assembly 5 can better connect with the previous process, so that the turnover box 2 can smoothly enter the cleaning machine.

[0054] refer to Figure 2 , Figure 4 In this embodiment, the entrance roller conveyor assembly 5 is arranged at the head end of the machine body 3. The box cover 2 first enters the entrance roller conveyor assembly 5 through the previous process, is conveyed backward for a distance through the entrance roller conveyor assembly 5, and then continues to be conveyed backward through the chain push plate conveyor assembly 7. The entrance roller conveyor assembly 5 includes a plurality of rollers 51 and an entrance conveying motor.

[0055] In a specific implementation provided in this embodiment, the rollers 51 are divided into two rows and arranged on both sides of the machine body 3. Each row includes a plurality of rollers 51. The rollers 51 transmit power through sprockets and chains, and the conveying power is provided by the inlet conveying motor. In the above structure, the turnover box 2 is in a horizontal state with its opening facing one side (see Fig.11 When the material enters the entrance roller conveyor assembly 5, it is conveyed backward by the rollers 51 on both sides until it reaches a suitable position and is then handed over to the chain push plate conveyor assembly 7 for further conveying.

[0056] Due to the structural limitations and working principles of the cleaning machine, in the overall cleaning line, under the condition of high-pressure water impact, a large force will be exerted on the turnover box 2. If rollers are used to transport the turnover box 2, it is difficult to ensure the normal transportation and cleaning effect of the turnover box 2 under the impact of water flow. Therefore, in this embodiment, the entrance roller conveyor assembly 5 is only used to connect to the previous workstation, and the transportation of the turnover box 2 in the cleaning machine is mainly completed by a reliable chain push plate conveyor assembly 7.

[0057] As shown in the reference figure, the chain push plate conveying assembly 7 extends from the front end to the rear end of the machine body 3, and penetrates the real strip cleaning line from front to back. The chain push plate conveying assembly 7 includes a conveying chain 73, a main conveying motor and a push plate 74, wherein the conveying chain 73 is arranged in a ring shape to realize continuous conveying, and is powered by the main conveying motor. The push plates 74 are installed on the conveying chain 73 at intervals, and the spacing between adjacent push plates 74 cannot be less than the length of the turnover box 2. In this way, the turnover box 2 can be pushed backward by the push plate 74. The push plate 74 can provide a large conveying force, and can still ensure the stable and reliable backward conveying of the turnover box 2 even under the impact of high-pressure water flow. It is an optimal main conveying method.

[0058] In the present application, the rollers 51 of the entrance roller conveyor assembly 5 are arranged in two rows at intervals, and a conveyor chain 73 is arranged in the middle position. The structural design of the two rows of rollers 51 just provides installation space for the middle conveyor chain line 73. When the turnover box 1 is conveyed backward to the end of the roller 51 on the entrance roller conveyor assembly 5, as the conveyor chain 73 rotates, when the push plate 74 moves to the position of the turnover box 1, the push plate 74 can continue to push the turnover box 1 to move backward. The present application provides a cleaning machine structure that occupies a small space in the width direction, and its overall structural layout is very compact. This also makes it very difficult to tighten the chain used to rotate the roller 51 in the entrance roller conveyor assembly 5. In the present application, a roller tensioning assembly 52 suitable for narrow spaces is designed. Reference Figure 8 As shown, the roller tensioning assembly 52 mainly includes a roller tensioning sprocket 521, and the roller tensioning sprocket 521 has a wheel shaft 522. The two ends of the wheel shaft 522 are supported by a bearing plate 523 respectively, and the bearing plate 523 is provided with a slide groove for the wheel shaft 522 to slide. The adjusting screw 524 is tapped and installed on the wheel shaft 522. The adjusting screw 524 is directly connected to the wheel shaft 522, which can greatly reduce the occupied space of the roller tensioning assembly 52. ​​By rotating the adjusting screw 524 to adjust the position of the wheel shaft 522, the corresponding chain can be tightened. It can be operated in a small space, solving the problem of limited space. When tightening, it is not necessary to disassemble other parts, and the operation is simple.

[0059] In a preferred specific embodiment provided by the present application, the annular conveyor chain 73 has supports at both the upper and lower parts. When conveying the turnover box 2, the conveyor chain 73 needs to be subjected to a large force. In order to prevent the conveyor chain 73 from deflecting and interfering with other structures, and to prevent the conveyor chain 73 from being gradually stretched due to gravity, the present application designs the following structure: an upper chain support rail 71, a lower chain support rail 72, and a roller 76. Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown in the figure, the push plate 74 is installed on the conveying chain 73, and two rollers 76 are provided on both sides of the push plate 74, wherein the installation position of the roller 76 is: the roller 76 is coaxially installed with the chain pin of the chain link, and the coaxial installation method makes the overall structure more compact and is also convenient for accessories with the support. Through the above structure, it can be known that when the conveyor chain 73 moves, the push plate 74 is driven to move, the conveyor chain 73 located at the upper part of the ring is located at the upper part of the chain support rail 71, and the roller 76 corresponding to the push plate 74 moves along the lower chain support rail 71, and the support is achieved through the upper chain support rail 71. The conveyor chain 73 located at the upper part of the ring is located above the lower chain support rail 72, and the roller 76 corresponding to the push plate 74 moves along the lower chain support rail 71. Because the push plate 74 is in a downward state when it is at the bottom, it generates gravity on the conveyor chain 73, and through the support of the lower chain support rail 71, it can withstand the gravity, avoid deformation of the chain under the action of gravity, and ensure the stability of the structure. At the same time, the lower chain support rail 71 is slotted in the middle to facilitate the extension of the push plate 74 to avoid interference.

[0060] In the present application, a chain tensioning assembly 75 is provided for tensioning the conveying chain 73. Figure 4 As shown, the chain tensioning assembly 75 is arranged below one side of the roller 51 of the inlet track conveying assembly 5, and the main power shaft is pushed to move by bolts to achieve the tension of the conveying chain 73.

[0061] As mentioned in the background technology, when the turnover box 1 enters the cleaning machine through the previous process, its opening is not completely horizontal. Fig.11 As shown, because the opening of the turnover box 1 has a rib plate, the opening is higher and the bottom is lower when the turnover box is laid flat, which causes a certain tilt state, and the cleaning effect is not ideal and it is easy to retain water stains. Therefore, in order to ensure the cleaning effect, it is necessary to adjust the turnover box 1 to a completely horizontal state of the opening. That is, after the turnover box 1 enters the inlet conveyor roller assembly 5, the turnover box 1 needs to be adjusted to flip it at a certain small angle to ensure the horizontal state of the opening.

[0062] refer to Figure 2 , Figure 4As shown, the turnover box alignment and reset assembly 8 provided by the present application can be used to make corresponding adjustments to the turnover box 1. Among them, the turnover box alignment and reset assembly 8 is arranged between the entrance roller conveyor assembly 5 and the exit roller conveyor assembly 9. When the turnover box 1 enters the chain push plate conveyor assembly 7 from the entrance roller conveyor assembly 5, it has a downhill section to gradually lower the opening of the turnover box until the opening is completely horizontal. After passing through the disinfection and cleaning process, it passes through an uphill section to restore it to its initial state, and finally outputs from the exit roller conveyor assembly 9 in its initial state, so as to smoothly connect with the next process.

[0063] The turnover box alignment and reset assembly 8 includes a turnover box top support rail 81 and a turnover box bottom support rail 82, which are respectively arranged on both sides of the chain push plate conveying assembly 7, and are respectively used to support and guide the top opening rib plate and the bottom of the turnover box. When the turnover box 1 enters the cleaning machine, its opening is in a higher direction, so it is only necessary to lower the position of its opening. The turnover box bottom support rail 82 is mainly used to support the bottom end of the turnover box 1, so the turnover box bottom support rail 82 is horizontally arranged, and its height is the same as the height of the roller 51. The same height enables the turnover box 1 to move smoothly from the roller 51 to the turnover box bottom support rail 82.

[0064] For the top support rail 81 of the turnover box, refer to Figure 6As shown, the top support guide rail 81 of the turnover box includes a downhill section 811, a horizontal section 812 and an uphill section 813, wherein the downhill section 811 is arranged at one end close to the entrance roller conveyor assembly 5, and the two ends of the downhill section 811 are respectively connected to the entrance roller conveyor assembly 5 and the horizontal section 812. At the entrance, in order to better connect the turnover box 1 with a certain tilt angle delivered by the front-end equipment, the roller 51 is used to convey the turnover box 1. After the turnover box 1 enters a certain position, the conveying chain 73 with the push plate 74 continues to convey the turnover box 1 forward. At the same time, in order to ensure that the turnover box 1 can rotate a certain angle after leaving the roller 51 (that is, the box mouth of the turnover box 1 is facing horizontal), a downhill section 811 is set on the top support rail 81 of the turnover box. The front end of the downhill section 811 is parallel to the height of the roller 51, and the lower end continues to tilt downward to the horizontal section 812, so that the turnover box 1 rotates a certain angle during the forward process, that is, after the turnover box 1 passes through the downhill section 811 and enters the horizontal section 812 (the height of the horizontal section 812 is lower than the bottom support rail 82 of the turnover box), the box mouth of the turnover box 1 changes from an inclined state to a horizontal state, and then enters the disinfection and cleaning station in a horizontal state. The design of this structure can make the turnover box 1 transition smoothly and avoid jamming during the transportation process. At the same time, through the design of this structure, it can be seen that during the transportation of the turnover box 1, the top support rail 81 and the bottom support rail 82 of the turnover box can realize the limiting guidance and support of the turnover box 1, thereby further ensuring the stability and flexibility of the turnover box 1 during transportation.

[0065] As for the uphill section 813, its two ends are connected with the exit roller conveyor assembly 9 and the horizontal section 812 respectively. When the turnover box 1 passes through the uphill section 813, it gradually resets to the initial state, thereby ensuring that the turnover box 1 is in the same state when entering and leaving the cleaning machine, which is convenient for connecting with other processes. Fig.11 The state shown is a schematic diagram of the case opening of the turnover box 1 changing from an inclined state to a horizontal state under the action of the turnover box straightening and resetting assembly 8.

[0066] In the present application, the cleaning machine can not only disinfect and clean the turnover box 1, but also disinfect and clean the box cover 2. The present application designs a highly integrated structure, which can not only complete the disinfection and cleaning of the turnover box 1 and the box cover 2, but also does not occupy additional space in the width direction. Figure 2 , Figure 4 as well as Figure 5As shown, the box cover guide assembly 6 is mainly used to guide the box cover 2. It includes a box cover bottom support rail 61 and a box cover upper end guide assembly 62. The box cover bottom end support rail 61 is arranged on one side of the conveying chain 73 and is in a U-shape with the opening upward. The box cover upper end guide assembly 62 is arranged directly above the box cover bottom end support rail 61. The box cover upper end guide assembly 62 is mainly composed of two guide rods. There is a gap between the two guide rods for the box cover 2 to pass through. The state of the box cover 2 during cleaning can be referred to Fig.12 shown.

[0067] In the present application, the conveying of the box cover 2 is also pushed by the push plate 74, and the push plate 71 extends from the position of the conveying chain 73 to the direction of the box cover bottom end support rail 61 to the top of the box cover bottom end support rail 61, so that the pushing position of the push plate 74 covers the conveying position of the turnover box 1 and the box cover 2, and can push the turnover box 1 and the box cover 2 to move. That is, when the box cover 2 needs to be disinfected and cleaned, the box cover 2 is placed between the box cover bottom end support rail 61 and the box cover upper end guide assembly 62, and the box cover 2 is pushed through the disinfection and cleaning stations in sequence by the moving push plate 74. In the above structure of the present application, it can be seen that the box cover upper end guide assembly 62 can not only guide the box cover 2, but also limit the upper part of the turnover box 1. During the transportation process, the turnover box 1 may accidentally deflect, causing the turnover box 1 to be supported on the push plate 74. When the turnover box 1 is supported on the push plate 74, its position will interfere with the upper nozzle, and the nozzle may be easily damaged during transportation (this is also based on our actual experience). In the present application, due to the limiting position of the guide assembly 62 at the upper end of the box cover, the turnover box 1 will not be supported on the push plate 74, and the turnover box 1 cannot move to a position that interferes with the nozzle, thereby ensuring the safety of the turnover box 1 during cleaning.

[0068] In the present application, the turnover box 1 is output through the outlet roller conveyor assembly 9 after cleaning. The outlet track conveyor assembly 9 is arranged at the end of the machine body 3, and it also includes multiple rollers and an outlet conveying motor. The structure and principle of the outlet roller conveyor assembly 9 are similar to those of the inlet roller conveyor assembly 5, and no further description is given here.

[0069] Medical waste may be damaged and leaked in the turnover box 1, and the waste may adhere to the inner wall of the turnover box 1. The waste may be large or small, and it will enter the circulating water of the turnover box 1 during the cleaning process. If it is not processed, it will clog the water pump and the nozzle. The disinfection and cleaning pipeline system 4 of the turnover box includes two water tanks 41, the front one is used for disinfection, and the rear one is used for flushing with clean water. In the traditional way, only one layer of filtering structure is set in the water tank 41, and the filtering accuracy is not enough, which can easily cause the nozzle and the water pump to be clogged. The disinfection and cleaning pipeline system 4 of the present application can solve the above problems.

[0070] refer to Fig. 9 , Fig.10 As shown. The disinfection and cleaning pipeline system 4 of the present application mainly includes a water tank 41, a water pump 42, and a nozzle 44, wherein an inclined filter screen 45 is arranged on the top of the water tank 41, a garbage box 46 is arranged on one side of the water tank 41, and the filter screen 45 is inclined toward the direction of the garbage box 46. A filter grid 47 is arranged on the side of the water tank 41 away from the garbage box 46, and a water pump water inlet 48 is arranged on the outside of the filter grid 47, and the filter screen 45, the filter grid 47 and the garbage box 46 all adopt a detachable connection structure. During disinfection and cleaning, the water in the reflux water tank first passes through the inclined detachable filter screen 45, and the garbage in the water will remain on the filter screen 45. Under the impact of water, this part of the garbage will be washed into the garbage box 46 on the right, which is convenient for the operator to clean; the refluxed water passes through the detachable filter grid 47 again before entering the water pump 42 again to continue circulation. The multi-stage filtration ensures the filtration accuracy and prevents the water pump and the nozzle from being blocked. The inclined filter screen 45, the garbage box 46 and the filter grille 47 make it more convenient for the operator to clean the garbage and clean the water tank.

[0071] In the disinfection and cleaning pipe system 4 of the present application, the water inlet pipe provides tap water to the water tank 41. The present design adds a stainless steel float valve that is easy to replace, which can realize automatic water replenishment of the water tank 41 during use.

[0072] In the traditional structural design, the water pump 42 of the cleaning machine is directly fixed on the main body of the cleaning machine, and is rigidly connected. The vibration generated during the operation of the water pump is directly transmitted to the main body of the cleaning machine, causing a large operating noise. In this application, a stainless steel flange rubber flexible joint 43 (throat) is added to the inlet and outlet of the water pump 42, and the fixing of the water pump 42 is separated from the cleaning machine. In order to prevent the water pump and the throat from being damaged by bumps during transportation, the fixing bracket of the water pump 42 is fixed to the main body of the cleaning machine with bolts. After the equipment is in place, the bolts can be removed, and the water pump 42 is independently fixed to the ground with anchor bolts, thereby reducing the operating noise.
