Technical Field
[0001] This utility model relates to the technical field of cleaning, sterilization and drying equipment, and in particular to a mobile spray cleaning device and a cleaning, sterilization and drying equipment adapted to freeze-drying trays. Background Technology
[0002] Vacuum freeze-drying, or freeze drying for short, is a drying method that involves freezing an object below its eutectic point temperature and then removing the moisture from the object through sublimation drying under high vacuum conditions. Freeze-dried powders obtained by this method have advantages such as maintaining the original activity and color of the object and being easy to store for a long time. Therefore, freeze-drying technology is widely used in food, pharmaceutical, biological, and agricultural fields.
[0003] Freeze-drying trays are essential loading containers in the freeze-drying process. Currently, the main types of freeze-drying trays on the market are stainless steel freeze-drying trays and disposable aseptic freeze-drying trays. Using disposable aseptic freeze-drying trays can reduce the risk of cross-contamination and ensure the quality of freeze-dried powder. However, disposable products cause resource waste, difficulties in recycling, high recycling costs, and environmental pollution. On the other hand, using stainless steel freeze-drying trays requires cleaning, sterilization, drying, transfer, and storage, which is a complex process with a high possibility of cross-contamination. In addition, the cleaning method for stainless steel freeze-drying trays is currently mainly manual cleaning. Manual cleaning has drawbacks such as uncontrollability, difficulty in guaranteeing cleaning quality, high labor load, low cleaning efficiency, and high labor costs. Utility Model Content
[0004] The technical problem this invention aims to solve is to provide a mobile spray cleaning device that can move along the front-to-back direction of materials and spray clean the bottom and sides of the materials. This device has a simple structure, is easy to operate, has low cost, good cleaning effect, and high cleaning efficiency. When the spray medium has a sterilizing effect, such as a high-temperature spray medium, in addition to spray cleaning, it can also spray sterilize the materials. This invention also provides a cleaning, sterilization, and drying equipment adapted for freeze-drying pallets, capable of loading large quantities of freeze-drying pallets and performing multi-directional cleaning, sterilization, and drying on these pallets. The freeze-drying pallets cleaned, sterilized, and dried by this equipment have a high degree of cleanliness.
[0005] Currently, the method for cleaning used stainless steel freeze-drying pallets is manual cleaning, followed by transfer to a sterilization cabinet for sterilization and drying. However, manual cleaning suffers from drawbacks such as uncontrollability, difficulty in ensuring cleaning quality, high labor intensity, low efficiency, and high labor costs. Therefore, this invention addresses these issues by designing a mobile spray cleaning device. This device can be used in conjunction with suspended loading carts carrying large quantities of freeze-drying pallets. By moving back and forth and utilizing rotating cleaning balls, the mobile spray cleaning device performs multi-directional cleaning, sterilization, and drying of the freeze-drying pallets within each suspended loading cart, ensuring cleaning quality and achieving very high cleaning efficiency.
[0006] The technical solution adopted by this utility model is: the mobile spray cleaning device includes: at least one mobile spray cleaning vehicle installed in a sterilization cabinet, characterized in that: when the number of mobile spray cleaning vehicles is two or more, each mobile spray cleaning vehicle is arranged in sequence from front to back;
[0007] The mobile spray cleaning vehicle includes: a bottom frame and a left mounting frame located on the left side of the bottom frame;
[0008] A walking mechanism is provided on the bottom frame, which can travel on the bottom track group inside the sterilization cabinet. Each mobile spray cleaning vehicle is driven by a drive device to move synchronously forward and backward along the bottom track group.
[0009] Several spray groups are arranged at intervals from top to bottom on the left mounting frame. Each spray group consists of several horizontal spray pipes arranged at intervals from front to back. Several upward spray heads are installed at intervals from left to right on the pipe wall of each horizontal spray pipe.
[0010] At least one vertical spray pipe is provided on the right side of the bottom frame, and several second spray heads spraying to the left are installed at intervals from top to bottom on the pipe wall of the vertical spray pipe;
[0011] The mobile spray cleaning vehicle is equipped with a water channel connecting each vertical spray pipe and each horizontal spray pipe. The water inlet of the water channel is sealed to the water inlet on the sterilization cabinet through a flexible hose.
[0012] Since the spray cleaning cart needs to move back and forth inside the sterilizer, the hose needs to be long enough to accommodate the back and forth movement of the spray cleaning cart. To facilitate hose management, a better solution is to fix a spring on the hose to suspend it inside the sterilizer. The spring has a tensile function and can pull the hose.
[0013] Furthermore, in the aforementioned mobile spray cleaning device, the structure of the driving device is as follows: a connecting frame is provided on the mobile spray cleaning vehicle; when there are two or more mobile spray cleaning vehicles, each mobile spray cleaning vehicle is connected through the connecting frame.
[0014] An insert hole is provided on the wall of the sterilizer at the rear of the sterilizer. An insert block is sealed and fixedly installed in the insert hole. The front end of the insert block is located inside the sterilizer, and the rear end of the insert block is located outside the sterilizer. A through channel is provided in the insert block.
[0015] The drive rod is sealed and inserted into the channel. The front end of the drive rod is fixedly connected to the rear end of the connecting frame on the mobile spray cleaning cart located at the rear end. The rear end of the drive rod has an internal threaded channel. The screw is screwed into the internal threaded channel. The rear end of the screw extending out of the internal threaded channel is fixedly connected to the output shaft of the reduction motor. The reduction motor is fixed on the platform outside the sterilization cabinet. The drive rod is circumferentially limited by the guide structure, so that when the screw rotates forward or backward, it can only force the drive rod to move forward or backward.
[0016] A corrugated pipe is fitted onto a drive rod located inside the sterilizer. A connecting block is fixedly installed on the front section of the drive rod. The front end of the corrugated pipe is sealed and fixedly connected to the connecting block, and the rear end of the corrugated pipe is sealed and fixedly connected to the mounting block.
[0017] Furthermore, in the aforementioned mobile spray cleaning device, a mounting block is provided on the rear end of the connecting frame, and a hemispherical positioning hole is provided inward on the rear end face of the mounting block. The drive rod head consists of, from front to back, a hemisphere that matches the hemispherical positioning hole, a connecting shaft with a diameter smaller than the diameter of the hemisphere, and a limiting member that is fixedly connected to the mounting block after being engaged with the connecting shaft, thereby confining the hemisphere in the hemispherical positioning hole.
[0018] This utility model also discloses a cleaning, sterilization and drying equipment adapted to freeze-drying trays. The equipment includes the mobile spray cleaning device mentioned in this solution; a number of rotating cleaning balls are installed on the top of the sterilization cabinet located above each spray device, and the inlet of each rotating cleaning ball is connected to a steam pipe.
[0019] The cleaning, sterilization and drying equipment adapted to freeze-drying trays also includes: at least one overhead loading vehicle with a horizontally placed lifting beam suspended from the top of the sterilizer from front to back;
[0020] The structure of the suspended loading vehicle includes: a suspension frame, which is composed of a bottom suspension frame, a right side suspension frame located on the right side of the bottom suspension frame, and a top suspension frame located on top of the right side suspension frame. A sliding mechanism is provided on the top of the top suspension frame, which can be suspended on the lifting beam and can slide along the axis of the lifting beam under the push of an external force. The space between the bottom suspension frame, the right side suspension frame, and the top suspension frame is a placement space for placing multiple freeze-drying pallets. Several sets of shelf groups for placing freeze-drying pallets are arranged at intervals from top to bottom on the right side suspension frame, and each shelf group is located in the placement space.
[0021] When the suspended loading vehicle enters any mobile spray cleaning device, a set of support frames enters the space between two adjacent spray groups. The right suspension frame enters the space between the vertical spray pipe and the right end of each spray group, and there are holes on the right suspension frame for the spray medium sprayed by each second spray head to pass through. The bottom suspension frame enters the space between the lowest spray group and the bottom frame.
[0022] Furthermore, in the aforementioned cleaning, sterilization, and drying equipment for adapting freeze-drying trays, the sliding mechanism comprises: a sliding seat provided at the top of the top suspension frame; a sliding groove provided downwards at the top of the sliding seat; at least two left-side guide wheels provided on the left side of the sliding groove; and at least two right-side guide wheels provided on the right side of the sliding groove. A space is formed between each left-side guide wheel, each right-side guide wheel, and the sliding groove for the hoisting beam to pass through. When the suspended loading vehicle is suspended on the hoisting beam, each left-side guide wheel and each right-side guide wheel rolls in contact with the upper arc surface of the hoisting beam, and the hoisting beam does not contact the sliding groove.
[0023] To ensure that the suspended loading vehicle does not tilt when suspended from the lifting beam, a more preferred solution is to install a counterweight on the right-side suspension frame.
[0024] To prevent water accumulation on the top surface of the top suspension frame, a more preferred solution is to have an inclined surface on the top surface of the top suspension frame. This can prevent water accumulation on the top surface of the top suspension frame from contaminating the cleaned, sterilized, and dried freeze-dried pallets or from contaminating the working environment during transport by the suspended loading vehicle.
[0025] The beneficial effects of this utility model are: ① The mobile spray cleaning device has a simple structure and is easy to operate; during operation, the mobile spray cleaning cart moves along the front and back direction of the material and sprays and cleans the bottom and sides of the material, resulting in good cleaning effect and high cleaning efficiency. When the spray medium has a sterilization effect, such as high-pressure spray medium, it can also sterilize in addition to spray cleaning; ② The mobile spray cleaning device can be used in conjunction with a suspended loading cart loaded with a large number of freeze-dried trays. The mobile spray cleaning device moves in the front and back direction, supplemented by rotating cleaning balls, to clean, sterilize and dry the freeze-dried trays in each suspended loading cart in multiple directions. The cleaning and sterilization are basically without dead corners, resulting in good cleaning effect and high cleaning efficiency, which greatly improves the cleanliness of the freeze-dried trays after cleaning, sterilization and drying.

Therefore, they should not be construed as limitations on this utility model.
[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example 1
[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the mobile spray cleaning device described in this embodiment includes: a mobile spray cleaning cart 2 installed inside the sterilization cabinet 1. The number of mobile spray cleaning carts 2 is at least one. When the number of mobile spray cleaning carts is two or more, each mobile spray cleaning cart is arranged sequentially from front to back in a straight line on the bottom track group 12 inside the sterilization cabinet 1.
[0044] The mobile spray cleaning vehicle 2 includes a bottom frame 21 and a left mounting frame 23 located on the left side of the bottom frame 21. A walking mechanism 22 is provided at the bottom of the bottom frame 21, capable of moving along a bottom track assembly 12 inside the sterilizer 1. The walking mechanism 22 can be a set of wheels or other structural forms that can move along the bottom track assembly 12; no limitation is made here, and the walking mechanism 22 is a conventional structure. The mobile spray cleaning vehicle 2 is driven by a drive unit to move forward or backward along the bottom track assembly 12. When there are two or more mobile spray cleaning vehicles 2, all mobile spray cleaning vehicles 2 are driven by the drive unit to move synchronously and in the same direction along the bottom track assembly 12.
[0045] On the left-side mounting frame 23, several spray groups 24 are arranged at intervals from top to bottom. Each spray group 24 consists of several horizontal spray pipes 241 arranged at intervals from front to back. On the pipe wall of each horizontal spray pipe 241, several upward spraying first spray heads 25 are installed at intervals from left to right.
[0046] At least one vertical spray pipe 26 is provided on the right side of the bottom frame 21, and several second spray heads 27 spraying to the left are installed at intervals from top to bottom on the pipe wall of the vertical spray pipe 26.
[0047] The mobile spray cleaning vehicle 2 is equipped with water channels connecting each vertical spray pipe 26 and each horizontal spray pipe 241. The inlet of the water channel is sealed to the inlet of the sterilizer 1 via a flexible hose 3. When there are two or more mobile spray cleaning vehicles 2, the flexible hose 3 on each mobile spray cleaning vehicle 2 is sealed to the same inlet on the sterilizer 1. Alternatively, multiple inlets can be provided on the sterilizer 1, with each flexible hose 3 corresponding to one inlet.
[0048] In use, the spraying medium is distributed to each vertical spray pipe 26 and each horizontal spray pipe 241 through the water inlet, hose 3, and water channel. The spraying medium is then sprayed outward through each first spray head 25 and each second spray head 27. The spraying medium can be selected according to actual needs. For example, if spray cleaning is required, cleaning water with a certain concentration of diluted cleaning agent can be selected. If sterilization is also required, the temperature of the cleaning water can be increased to the sterilization temperature requirement.
[0049] Since the mobile spray cleaning vehicle 2 needs to move back and forth along the bottom track assembly 12 during the spray cleaning process, the hose 3 needs to have a certain length. For easier management of the hose 3, a more preferable solution is to fix a spring 4 on the hose 3 to suspend it inside the sterilizer 1. Figure 3 As shown.
[0050] When there is only one mobile spray cleaning vehicle 2, a connecting frame is provided on it. When there are two or more mobile spray cleaning vehicles 2, a connecting frame can be provided on each vehicle, with the connecting frame on the rear vehicle connected to the connecting frame on the front vehicle, thus connecting all the mobile spray cleaning vehicles into a line. Alternatively, the connecting frame can be long and narrow, with all mobile spray cleaning vehicles 2 fixed to this long and narrow connecting frame 28.
[0051] When one mobile spray cleaning vehicle 2 is installed, the drive unit is connected to the connecting frame of the mobile spray cleaning vehicle 2. When two or more mobile spray cleaning vehicles 2 are installed, the positional relationship between the connecting frame 28 and the drive unit and the structure of the drive unit will be explained as an example, taking all mobile spray cleaning vehicles 2 as fixed on the long strip connecting frame 28.
[0052] The above-mentioned mobile spray cleaning device has a simple structure and is easy to operate. When working, the mobile spray cleaning vehicle 2 moves along the front and back direction of the material and sprays and cleans the bottom and sides of the material. The cleaning effect is good and the cleaning efficiency is high. When the spray medium has a sterilization effect, such as high temperature spray medium, sterilization can be performed in addition to spray cleaning.
[0053] Drive units have many structural forms. Considering the optimization of the overall structure and the operating environment, the drive unit is designed as follows: Figure 7 and Figure 8 As shown, the structure of the driving device in this embodiment is as follows: an insert hole is provided on the sterilization cabinet wall at the rear of the sterilization cabinet 1, and an insert block 13 is sealed and fixedly installed in the insert hole. The front end of the insert block 13 is located inside the sterilization cabinet 1, and the rear end of the insert block 13 is located outside the sterilization cabinet 1. A through channel 131 is provided in the insert block 13.
[0054] The drive rod 7 is sealed and inserted into the channel 131. The front end of the drive rod 7 is fixedly connected to the rear end of the connecting frame 28. The rear end of the drive rod 7 has an inwardly threaded channel 71. The screw 8 is screwed into the threaded channel 71. The rear end of the screw 8 extending out of the threaded channel 71 is fixedly connected to the output shaft of the reduction motor 81. The reduction motor 81 is fixed on the platform 6 outside the sterilizer 1. The drive rod 7 is circumferentially limited by a guide structure, so that when the screw 8 rotates forward or backward, it can only force the drive rod 7 to move forward or backward. Here, the guide structure can be a guide rail slider structure, a guide rod sleeve structure, or other structures available on the market. The guide structure is a conventional structure in this field, so it will not be described in detail here. The drive rod 7 can be set on the platform 6 through the guide structure.
[0055] like Figure 8 and Figure 9 As shown, in this embodiment, a bellows 9 is fitted onto the drive rod 7 located inside the sterilizer 1. A connecting block 74 is fixedly installed on the front section of the drive rod 7. The front end of the bellows 9 is sealed and fixedly connected to the connecting block 74, and the rear end of the bellows 9 is sealed and fixedly connected to the mounting block 13. The sealing method between the front end of the bellows 9 and the connecting block 74, and the sealing method between the rear end of the bellows 9 and the mounting block 13, can use sealing rings or other sealing structures; these are not strictly required, as long as the required sealing is achieved. The bellows 9 ensures that the fluid in the sterilizer 1 will not leak out through this drive structure during the forward or backward movement of the drive rod 7.
[0056] The front end of the drive rod 7 is fixedly connected to the connecting frame 28 in the following structure: Figure 9As shown, a mounting block 281 is provided on the rear end of the connecting frame 28. A hemispherical positioning hole 282 is formed inward on the rear end face of the mounting block 281. The head of the drive rod 7 consists of, from front to back: a hemisphere 72 that matches the hemispherical positioning hole 282, and a connecting shaft 73 with a diameter smaller than the diameter of the hemisphere. The limiting member 10 is fixedly connected to the mounting block 281 after being engaged with the connecting shaft 73, thereby confining the hemisphere 72 in the hemispherical positioning hole 281. In actual installation, it is difficult to ensure that the connecting frame 28 and the drive rod 7 are completely aligned on the same axis. In addition, wear during use can also lead to errors. The above structure has a self-adjusting function. When the connecting frame 28 and the drive rod 7 are not completely aligned on the same axis and there are installation errors, or after long-term use and wear, the hemisphere 72 can be adjusted by cooperating with the hemispherical positioning hole 282 to ensure that the drive structure can still operate smoothly. Example 2
[0057] The cleaning, sterilization and drying equipment adapted to freeze-drying trays described in this embodiment includes the mobile spray cleaning device described in Embodiment 1; a number of rotating cleaning balls are provided on the top of the sterilization cabinet 1 located above each spray device, and the inlet of each rotating cleaning ball is connected to a steam pipe.
[0058] The cleaning, sterilization and drying equipment adapted to freeze-drying trays also includes: at least one suspended loading trolley 5, with a lifting beam 11 suspended horizontally from front to back above the sterilization cabinet 1.
[0059] like Figure 5 , Figure 6 and Figure 7 As shown, the structure of the suspended loading vehicle 5 in this embodiment includes: a suspension frame, which is composed of a bottom suspension frame 51, a right side suspension frame 52 located on the right side of the bottom suspension frame 51, and a top suspension frame 53 located on the top of the right side suspension frame 52. A sliding mechanism is provided on the top of the top suspension frame 53, which can be suspended on the lifting beam 11 and can slide along the axis of the lifting beam 11 under the push of an external force.
[0060] There is also an external lifting beam outside the sterilizer 1 that can connect with the lifting beam 11. The suspended loading vehicle 5 can be transferred from outside the sterilizer 1 to the lifting beam 11 inside the sterilizer 1 via the external lifting beam, or from inside the sterilizer 1 to outside the sterilizer 1 via the lifting beam 11 inside the sterilizer 1.
[0061] like Figure 5 and Figure 6As shown, the sliding mechanism in this embodiment is as follows: a sliding seat 54 is provided on the top of the top suspension frame 53, a sliding groove 541 is provided downward on the top of the sliding seat 54, at least two left guide wheels 542 are provided on the left side of the sliding groove 541, and at least two right guide wheels 543 are provided on the right side of the sliding groove 541. A space for the hoisting beam 11 to pass through is formed between each left guide wheel 542, each right guide wheel 543 and the sliding groove 541. When the suspended loading vehicle 5 is suspended on the hoisting beam 11, each left guide wheel 542 and each right guide wheel 543 roll in contact with the upper arc surface of the hoisting beam 11, and the hoisting beam 11 does not contact the sliding groove 541.
[0062] The space between the bottom suspension frame 51, the right side suspension frame 52, and the top suspension frame 53 is a placement space for multiple freeze-drying trays. Several sets of shelving units 55 are spaced at intervals from top to bottom on the right side suspension frame 52. Each shelving unit 55 is located within the placement space, and at least one freeze-drying tray is placed on each shelving unit 55 from front to back. The structure of the shelving units can be designed according to the structure of the freeze-drying trays. When each shelving unit 55 holds one freeze-drying tray, there can be two shelving rods that can support the trays through the wings on both sides of the freeze-drying tray. The freeze-drying trays will not detach from the shelving rods under the impact of the spray. When each shelving unit 55 holds at least two freeze-drying trays, the number of shelving rods increases accordingly.
[0063] When the suspended loading trolley 5 enters any of the mobile spray cleaning devices, a set of support frames 55 enters the space between two adjacent spray groups. The right suspension frame 52 enters the space between the vertical spray pipe 26 and the right end of each spray group 24, and the right suspension frame 52 has holes through which the spray medium sprayed by each second spray head 27 passes. The bottom suspension frame 51 enters the space between the lowest spray group 24 and the bottom frame 21. At this time, during the back-and-forth movement of the suspended loading trolley 5 on the lifting beam 11 under the action of external force, the suspended loading trolley 5 and the freeze-drying pallets loaded on it will not touch any parts of the mobile spray cleaning trolley 2. During the back-and-forth movement of the mobile spray cleaning trolley 2 on the bottom track group 12, no part of the mobile spray cleaning trolley 2 will touch the suspended loading trolley 5 or the freeze-drying pallets loaded on it.
[0064] Each freeze-drying tray placed on the shelf assembly 55 has its side facing down, with the side carrying the items facing down. At this time, each first spray head 25 sprays upwards, spraying and rinsing the side carrying the items. Here, the right frame 52 can be constructed by splicing several beams and connecting them with screws, welding, or other fixed connections. In this case, the gap between the beams is the hole through which the spray medium sprayed by each second spray head 27 passes, and the side of the freeze-drying tray is sprayed and rinsed through each second spray head 27.
[0065] When the mobile spray cleaning device is used in conjunction with the suspended loading vehicle 5 carrying a large number of freeze-dried trays, the mobile spray cleaning device moves back and forth and is supplemented by rotating cleaning balls to clean, sterilize and dry the freeze-dried trays in each suspended loading vehicle 5 in multiple directions. The cleaning and sterilization are basically without dead corners, which greatly improves the cleanliness after cleaning and sterilization, ensures the cleaning quality, and greatly improves the cleaning efficiency.
[0066] To ensure that the suspended loading vehicle 5 does not tilt when suspended from the lifting beam 11, a counterweight 521 is provided on the right side frame 52; the top surface of the top frame 53 is an inclined surface 531. The inclined surface 531 is designed to guide the condensate generated during the freeze-drying process to slide down and not accumulate on the top surface of the top frame 53. In addition, it can also prevent cleaning water and condensate from accumulating on the top surface of the top frame 53 during the cleaning and sterilization process.
[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any modifications or equivalent changes made based on the technical essence of the present utility model shall still fall within the scope of protection claimed by the present utility model.
