The design of their door opening and closing structure directly affects the ease of use, sealing, and safety of the equipment. For example, some existing freeze dryers use the traditional hinged door opening method, which requires a large operating space when opening the door. This is extremely inconvenient when used in places with limited space, such as laboratories. In addition, the door opening angle is limited, which is not conducive to the rapid loading and unloading of materials.

[0003] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a sliding door structure for a pilot-scale freeze dryer to solve the problem that some existing freeze dryers use a traditional hinged door opening method, which requires a large operating space when opening the door, making it extremely inconvenient to use in places with limited space such as laboratories. In addition, the door opening angle is limited, which is not conducive to the rapid loading and unloading of materials. Utility Model Content

[0004] This utility model proposes a sliding door structure for a pilot-scale freeze dryer, which solves the problem that some existing freeze dryers use a traditional hinged door opening method, which requires a large operating space when opening the door, making it extremely inconvenient to use in places with limited space such as laboratories, and the door opening angle is limited, which is not conducive to the rapid loading and unloading of materials.

[0005] The technical solution of this utility model is implemented as follows: A pilot-scale freeze dryer sliding door structure includes: a freeze dryer body, two guide grooves are provided in a straight line array on the front end face of the freeze dryer body, and a horizontally arranged guide plate is also fixedly connected to the front end face of the freeze dryer body.

[0006] The guide groove is internally slidably connected to a block assembly. There are two block assemblies, and each of the two block assemblies has two protruding guide block assemblies fixedly connected to its upper and lower sides. A hatch mechanism is also fixedly connected to the front end of the two block assemblies. Two sets of mounting plates are fixedly connected in a linear array to the bottom end of the hatch mechanism. The inner side of the mounting plates is rotatably connected to a moving wheel.

[0007] In a preferred embodiment, the movable wheel is slidably connected to the guide plate, and four casters are installed on the bottom surface of the freeze dryer body.

[0008] In a preferred embodiment, the four casters are fixedly connected to the four corners of the bottom surface of the freeze dryer body, and a control panel is fixedly connected to the right side of the front surface of the freeze dryer body. A controller is also fixedly connected to the front of the freeze dryer body.

[0009] In a preferred embodiment, the controller is connected to the control panel, and heat dissipation slots are arranged in a rectangular array on the front surface of the freeze dryer body.

[0010] In a preferred embodiment, a cavity is provided on the front end face of the freeze dryer body. Inside the cavity, three partition mechanisms are fixedly connected in a linear array. The partition mechanisms and the freeze dryer body together form a support structure.

[0011] In a preferred embodiment, the door mechanism has a through slot inside, and a closed window made of plexiglass is embedded inside the through slot. The door mechanism and the closed window together form a closed structure for the opening at the front of the freeze dryer body.

[0012] In a preferred embodiment, a slot assembly is provided on the front end face of the hatch mechanism. There are two slot assemblies, which are provided opposite to each other on the left and right sides of the front end face of the hatch mechanism. The slot assembly is used for inserting a hand to push the hatch mechanism.

[0013] After using the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by adopting a sliding door structure, compared with the traditional hinged door opening method, no large operating space is required when opening the door. In places with limited space such as laboratories, operators can easily open and close the door mechanism, avoiding the inconvenience caused by the limited opening angle of the door, and greatly improving the ease of use of the equipment in small spaces. For example, in a laboratory with limited space, a traditional hinged freeze dryer may not be able to fully open the door due to the obstruction of surrounding equipment or obstacles, while the sliding door of this equipment can be opened smoothly, which is convenient for loading and unloading materials.

[0015] 2. In this utility model, the sliding door mechanism opens and closes smoothly and conveniently. Through the cooperation of components such as the slot assembly, moving wheels, guide groove and guide plate, the operator can quickly complete the opening and closing of the door. This makes the loading and unloading of materials more efficient, reduces the time that materials are exposed to the external environment, and helps to maintain the quality and characteristics of materials. It solves the problem that the traditional hinged door opening method is not conducive to the rapid loading and unloading of materials, and meets the needs of fields such as drug research and development and biological product preparation that have high requirements for material handling efficiency.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6As shown, a pilot-scale freeze dryer sliding door structure includes: a freeze dryer body 1, two guide grooves 201 are provided in a straight array on the front end face of the freeze dryer body 1, and a horizontally arranged guide plate 2011 is also fixedly connected to the front end face of the freeze dryer body 1.

[0026] The guide groove 201 is internally slidably connected to a block assembly 3012. There are two blocks assemblies 3012, and two protruding guide assemblies 3013 are fixedly connected to each other on the upper and lower sides of the two blocks assemblies 3012. The front end face of the two blocks assemblies 3012 is also fixedly connected to a hatch mechanism 3. The bottom end face of the hatch mechanism 3 is fixedly connected to two sets of mounting plates 3014 in a linear array. The inner side of the mounting plate 3014 is rotatably connected to a moving wheel 3015.

[0027] Among them, the movable wheel 3015 is slidably connected to the guide plate 2011, and the bottom surface of the freeze dryer body 1 is equipped with a universal wheel 101. There are four universal wheels 101 in total, and the four universal wheels 101 are respectively fixedly connected to the four corners of the bottom surface of the freeze dryer body 1. The right side of the front surface of the freeze dryer body 1 is fixedly connected to the control panel 1011, and the front end of the freeze dryer body 1 is also fixedly connected to the controller 1012.

[0028] The controller 1012 is connected to the control panel 1011, and the front end face of the freeze dryer body 1 has a rectangular array of heat dissipation slots 1013. The front end face of the freeze dryer body 1 has a cavity, and three partition mechanisms 2 are fixedly connected in a linear array inside the cavity. The partition mechanisms 2 and the freeze dryer body 1 together form a support structure.

[0029] The door mechanism 3 has a through slot inside, and a closed window 301 with an organic glass structure is embedded inside the through slot. The door mechanism 3 and the closed window 301 together form a closed structure for the front opening of the freeze dryer body 1. The front surface of the door mechanism 3 has a slot assembly 3011. There are two slot assemblies 3011, which are opened opposite each other on the left and right sides of the front surface of the door mechanism 3. The slot assembly 3011 is used for inserting a hand to push the door mechanism 3.

[0030] When in use, the operator pushes the freeze dryer body 1, and the four casters 101 installed at the four corners of its bottom can rotate flexibly, making it easy to move the equipment to the required work location. After arriving at the location, if it is necessary to fix the equipment, the casters 101 can be braked to ensure that the equipment remains stable during operation.

[0031] The operator inserts their hand into any of the slot components 3011 on the left or right sides of the front face of the door mechanism 3 and pushes the door mechanism 3 by applying force with their hand. At this time, the moving wheel 3015, which is rotatably connected to the inner side of the mounting plate 3014 at the bottom of the door mechanism 3, slides on the guide plate 2011. At the same time, the insertion block component 3012, which is fixedly connected to the door mechanism 3, slides in the guide groove 201. The guide block components 3013 on the upper and lower sides of the insertion block component 3012 play an auxiliary guiding and stabilizing role, ensuring that the door mechanism 3 slides smoothly to one side until the front opening of the freeze dryer body 1 is exposed, thus completing the door opening action.

[0032] After the door is opened, the operator can place the material to be freeze-dried inside the freeze dryer body 1, or take out the freeze-dried material from inside. After placing or taking out the material, push the door mechanism 3 again to make it move in the opposite direction according to the above sliding method until the door mechanism 3 closes, sealing the front opening of the freeze dryer body 1. The sealing window 301 is made of plexiglass. During the closing process of the door, it is embedded in the through groove inside the door mechanism 3, and together with the door mechanism 3, it forms a sealing structure for the front opening of the freeze dryer body 1, ensuring the airtightness of the equipment and providing a good environment for subsequent freeze-drying operations.

[0033] Equipment Operation and Control: Operators set equipment operating parameters, such as freeze-drying temperature and time, through the control panel 1011. The control panel 1011 is connected to the controller 1012. The set parameter information is transmitted to the controller 1012. The controller 1012 controls the operation of each component inside the freeze dryer body 1 according to the received parameter information to achieve precise control of the freeze-drying process. During equipment operation, the freeze dryer body 1 generates heat. The heat dissipation slots 1013 arranged in a rectangular array on the front surface can dissipate the heat, maintain a suitable temperature environment inside the equipment, and ensure normal operation of the equipment.

[0034] Internal support and material placement: Three partition mechanisms 2 are fixedly connected in the cavity of the front end of the freeze dryer body 1. The partition mechanisms 2 and the freeze dryer body 1 together form a support structure, which not only enhances the structural stability of the freeze dryer body 1, but also provides layered support for the placement of materials, making it easier to arrange the placement of materials and improve space utilization.
