Description

Technical Field

[0001] This utility model belongs to the field of freeze dryer equipment, and specifically relates to a pull-down switch door structure for a pilot-scale freeze dryer. Background Technology

[0002] Currently, in the use of pilot-scale freeze dryers, the rationality of the door structure design has a significant impact on the overall performance of the equipment. Common door structures for pilot-scale freeze dryers, such as side-opening doors and top-opening doors, have many drawbacks. Side-opening doors require a large lateral space when opened, which can easily interfere with surrounding equipment and experimental tables in pilot-scale workshops or laboratories with limited space, affecting not only operational convenience but also potentially causing equipment damage. While top-opening doors save lateral space to some extent, the door body swings upward when opened, increasing the overall vertical space requirement of the equipment, which is extremely inconvenient for places with limited ceiling height. Furthermore, it poses a safety hazard of operators bumping their heads during operation.

[0003] Therefore, considering the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. In the spirit of striving for excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. Specifically, a pull-down door structure for a pilot-scale freeze dryer is provided to address the problem that existing side-opening doors require a large lateral space when opened, which can easily interfere with surrounding equipment and experimental tables in space-constrained pilot-scale workshops or laboratories, affecting not only operational convenience but also potential equipment damage. While top-opening doors save lateral space to some extent, the door body swings upwards when opened, increasing the overall vertical space requirement of the equipment, which is extremely inconvenient for locations with limited ceiling height. Furthermore, it poses a safety hazard of operators bumping their heads during operation. Utility Model Content

[0004] This invention proposes a pull-down door structure for a pilot-scale freeze dryer, which solves the problem that existing side-opening doors require a large lateral space when opened, which can easily interfere with surrounding equipment and experimental tables in pilot-scale workshops or laboratories with limited space, affecting not only operational convenience but also potential equipment damage. While top-opening doors save lateral space to some extent, the door body swings upward when opened, increasing the overall vertical space requirement of the equipment, which is extremely inconvenient for places with limited ceiling height. In addition, there is a safety hazard of operators bumping their heads during operation.

[0005] The technical solution of this utility model is implemented as follows: A pilot-scale freeze dryer pull-down switch door structure includes: a freeze dryer body, two longitudinally arranged mounting grooves are opened in a straight array on the front end face of the freeze dryer body, a sling assembly is fixedly connected to the inner side of the two mounting grooves, and a damping hinge is hinged to the front end of the freeze dryer body.

[0006] The damping hinges are provided in two locations, arranged in a linear array on the left and right sides of the front face of the freeze dryer body. A door assembly is fixedly connected to the front end of each of the two damping hinges, and the door assembly is used to close the front opening of the freeze dryer body.

[0007] In a preferred embodiment, a closed window is embedded on the inner side of the hatch assembly, and an L-shaped handle is fixedly connected to the front face of the hatch assembly.

[0009] In a preferred embodiment, the freeze dryer body and the partition assembly together form a load-bearing structure, and a groove is provided on the front end face of the freeze dryer body, and a magnetic ring of an electromagnet structure is fixedly connected inside the groove.

[0010] In a preferred embodiment, the magnetic ring is matched with the hatch assembly. When the magnetic ring is energized and generates magnetism, the hatch assembly is in a state of being attracted, limited, and tightened.

[0011] In a preferred embodiment, two longitudinal grooves are arranged in a straight line on the rear end face of the freeze dryer body. A servo push rod is fixedly connected inside the longitudinal groove, and there are two servo push rods in total.

[0012] In a preferred embodiment, a movable component is fixedly connected to the bottom end face of both servo push rods.

The movable component is slidably connected to the rear side of the freeze dryer body through the slider components fixedly connected to its outer side. A support component with a triangular cross-section is also fixedly connected to the outer side of the movable component.

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

[0014] 1. In this utility model, the pull-down door assembly does not require lateral space when opened, avoiding interference with surrounding equipment and experimental tables in narrow pilot plant or laboratory, significantly improving operational convenience and reducing the risk of equipment damage. At the same time, compared with the top-opening door, the pull-down door does not increase the overall vertical space requirement of the equipment, and operators do not need to worry about bumping their heads, making operation safer and more convenient, effectively solving the shortcomings of traditional door structures in terms of space utilization and operational convenience.

[0015] 2. In this utility model, the design of the magnetic suction ring adsorbing the door assembly allows the door to fit tightly against the freeze dryer body when closed, enhancing the sealing effect, ensuring the stability of the internal environment of the freeze dryer, and improving the quality of freeze-dried products. In addition, the combination of servo push rod, moving component and support component can provide additional support for the freeze dryer body when needed, enhancing the stability of the equipment, making up for the shortcomings of traditional freeze dryers in terms of stability, and ensuring that the equipment is more reliable during operation.

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 1-6 As shown, a pilot-scale freeze dryer pull-down switch door structure includes: a freeze dryer body 1, two longitudinally arranged mounting grooves 2 are provided in a straight array on the front end face of the freeze dryer body 1, a sling assembly 201 is fixedly connected to the inner side of the two mounting grooves 2, and a damping hinge 2014 is hinged to the front end of the freeze dryer body 1.

[0026] There are two damping hinges 2014. The two damping hinges 2014 are installed in a straight array on the left and right sides of the front end face of the freeze dryer body 1. The front end of the two damping hinges 2014 is also fixedly connected to the door assembly 2011, which is used to close the front opening of the freeze dryer body 1.

[0027] The door assembly 2011 has a sealed window 2012 embedded inside, and an L-shaped handle 2013 is fixedly connected to the front end of the door assembly 2011. The four corners of the bottom surface of the freeze dryer body 1 are equipped with self-locking casters 101. The front groove of the freeze dryer body 1 has a partition assembly 1011 fixedly connected in a straight line array.

[0028] The freeze dryer body 1 and the partition assembly 1011 together form a load-bearing structure, and a groove is provided on the front end face of the freeze dryer body 1. A magnetic ring 1012 with an electromagnet structure is fixedly connected inside the groove.

[0029] Among them, the magnetic ring 1012 is matched with the door assembly 2011. When the magnetic ring 1012 is energized and generates magnetism, the door assembly 2011 is in a state of being attracted, limited and tightened. Two longitudinal grooves are opened in a straight array on the rear end face of the freeze dryer body 1. Servo push rods 3 are fixedly connected inside the longitudinal grooves. There are two servo push rods 3. A moving component 301 is fixedly connected to the bottom end face of each of the two servo push rods 3. Two slider assemblies 3011 with protruding structures are fixedly connected to the outside of the moving component 301 in opposite directions. The moving component 301 is slidably connected to the rear side of the freeze dryer body 1 through the slider assemblies 3011 fixedly connected to its outside. A support component 3012 with a triangular cross-section is also fixedly connected to the outside of the moving component 301.

[0030] When in use, if it is necessary to open the door assembly 2011, first disconnect the power to the magnetic ring 1012 to demagnetize it and release the attraction limit on the door assembly 2011. Then, the operator holds the handle 2013 on the front surface of the door assembly 2011 and pulls the door assembly 2011 downward. Since the door assembly 2011 is hinged to the freeze dryer body 1 through the damping hinge 2014, the damping hinge 2014 plays a buffering and stabilizing role during the pulling process, ensuring that the door assembly 2011 moves downward smoothly. At the same time, the sling assembly 201 inside the mounting slot 2 will also extend as the door assembly 2011 descends, providing auxiliary support and guidance for the door assembly 2011 and preventing the door assembly 2011 from shaking or deviating during the descent.

[0031] After completing material loading and unloading or equipment maintenance, the door assembly 2011 needs to be closed. The operator holds the handle 2013 and pushes the door assembly 2011 upward. Under the action of the damping hinge 2014, the door assembly 2011 moves upward slowly, and the sling assembly 201 gradually retracts. When the door assembly 2011 rises to the near-closed position, the magnetic ring 1012 is energized. The magnetic ring 1012 generates magnetism, attracting and tightening the door assembly 2011, so that it fits tightly against the front opening of the freeze dryer body 1, thus completing the closure and sealing of the door.

[0032] If it is necessary to move the freeze dryer body 1, the self-locking mechanism of the caster wheel 101 can be released. The freeze dryer body 1 can be moved by pushing the caster wheel 101. After the freeze dryer body 1 is moved to the designated position, the caster wheel 101 can be locked again to fix the equipment. If additional support is needed for the freeze dryer body 1, the servo push rod 3 can be activated. The servo push rod 3 extends and drives the moving component 301 to move downward. The slider component 3011 on the outside of the moving component 301 slides in the longitudinal groove on the rear side of the freeze dryer body 1 to ensure that the moving component 301 descends smoothly. When the support component 3012 contacts the ground and reaches the appropriate support force, the action of the servo push rod 3 is stopped. The support component 3012 provides stable additional support for the freeze dryer body 1 and enhances the stability of the equipment during use.
