Description

Technical Field

[0001] This utility model relates to the field of freeze-drying equipment technology, and in particular to a cascade ultra-low dew point freeze dryer. Background Technology

[0002] The cascade ultra-low dew point freeze dryer is a compressed air drying device that achieves extremely low dew points by combining different drying technologies. It combines the advantages of freeze drying and adsorption drying, using multi-stage processing to achieve ultra-low dew point air drying. As a highly efficient and high-quality method for material drying and preservation, the cascade ultra-low dew point freeze dryer plays an important role in many fields. In the future, with continuous technological advancements and sustained growth in market demand, this equipment will demonstrate its unique charm and value in even more areas.

[0003] In existing technologies, cascade ultra-low dew point freeze dryers filter air through their filter elements during operation. This step is crucial for reducing the impact of impurities and airborne particles on the system. However, filter elements used for extended periods require regular inspection and replacement to ensure equipment efficiency and stability. Existing equipment is designed with complex filter element replacement procedures, which not only increases maintenance difficulty but also leads to a significant reduction in work efficiency, thus affecting the efficiency of the entire production process. The cumbersome operation process often requires professional personnel to spend considerable time and effort, which not only increases the company's operating costs but also forces the production line to stop during filter element replacement, thereby reducing production efficiency. Furthermore, the complex replacement process also increases the risk of equipment damage due to improper operation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cascade ultra-low dew point freeze dryer.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a cascade ultra-low dew point freeze dryer, comprising a freeze drying equipment body, a filter fixed to the inner wall of the freeze drying equipment body, a filter element module provided on the inner wall of the filter, hook grooves on both sides of the inner wall of the filter, an installation frame fixed to the top of the hook grooves, a pressure rod slidably connected to the inner wall of the installation frame, a track component fixed to one end of the pressure rod, a return spring fixed to one end of the track component, one end of the return spring fixed to the inner wall of the installation frame, and the top of the installation frame... An L-shaped hook rail component is rotatably connected. One end of the L-shaped hook rail component is slidably connected to the inner wall of the top rail of the rail component. An inverted U-shaped frame rail frame is fixed at the bottom of the rail component. A sliding groove rod is slidably connected to the inner wall of the inverted U-shaped frame rail frame. A fixing hook is fixed to the circumference of the sliding groove rod. A rotating base rod is fixed to both sides of the fixing hook. A swivel member is rotatably connected to one end of the rotating base rod. The top of the swivel member is fixed to the bottom of the mounting frame. A side bottom groove is opened on one side of the bottom of the filter module. An arc-shaped step member is fixed to the inner wall of the side bottom groove. A fixing rectangular groove is opened at the bottom of the arc-shaped step member.

[0006] Preferably, the inner wall of the mounting frame is provided with limiting ladder grooves on both sides, and limiting ladder members are fixed on both sides of the track component. The surface of the limiting ladder member is slidably connected to the inner wall of the limiting ladder groove. In the prior art, the track component is easily affected by external environmental factors, vibration interference from adjacent equipment, and instability caused by manual pushing by the operator during operation. These factors combined cause the track component to be unable to maintain a constant parallel state relative to its ideal trajectory during movement. This non-parallel movement not only causes additional friction and wear between the track component and the components it contacts, reducing the overall operating efficiency of the equipment, but also accelerates the aging or damage of some components due to uneven dynamic load distribution. Over time, this unstable movement state leads to a decrease in the operational reliability of the entire system, manifested as increased mechanical vibration, reduced positioning accuracy, and in severe cases, even equipment failure and shutdown, causing unnecessary interruptions and losses to production activities. To address this problem, this utility model uses the installation of limiting ladder members to solve the problem. By coordinating the limiting ladder members with the limiting ladder grooves, the mounting frame always maintains a stable movement path, ensuring smooth movement while preventing abnormal wear between components, thereby improving the service life of the equipment.

[0007] Preferably, a pressure pad is fixed to one end of the pressure rod. In the prior art, during the contact process between the pressure rod and the arc-shaped ladder component, the contact area between the two is relatively small, resulting in a significant increase in pressure at the contact point. If this high-pressure state continues for a long time, the surface of the arc-shaped ladder component will gradually be eroded and worn. With the passage of time and the increase in usage frequency, this wear phenomenon of the arc-shaped ladder component will become more and more serious, thereby affecting the normal operation and service life of the entire equipment. Wear not only leads to a decline in equipment performance, but also triggers a chain reaction in other components, ultimately causing overall equipment failure or premature scrapping. To address this problem, this utility model solves it by installing a pressure pad, which greatly increases the contact area between the pressure rod and the arc-shaped ladder component, thereby reducing the pressure at the contact area, preventing damage to the arc-shaped ladder component, and achieving the effect of improving the service life of the equipment.

[0008] Preferably, both ends of the inner wall of the limiting ladder groove are glued and fixed with groove end pads, which can prevent collision and wear between components and improve the service life of the equipment.

[0009] Preferably, the bottom arc surface of the arc-shaped component is provided with a hand grip groove, which facilitates operation by staff and improves the user experience.

[0010] Preferably, the freeze-drying equipment has reinforcing ribs fixed to the side of the main body, which strengthens the stability of the equipment shell and improves the service life of the equipment.

[0011] Preferably, the edges of the freeze-drying equipment are all fixed with edge-binding arc ribs, which reduces the wear of components during transportation and improves the service life of the equipment.

[0012] Beneficial effects:

[0013] 1. In existing technologies, cascade ultra-low dew point freeze dryers filter air through their filter elements during operation. This step is crucial for reducing the impact of impurities and airborne particles on the system. However, filter elements used for extended periods require regular inspection and replacement to ensure equipment efficiency and stability. Existing equipment has a complex filter element replacement design, which not only increases maintenance difficulty but also leads to a significant reduction in work efficiency, thus affecting the efficiency of the entire production process. The operation is cumbersome, often requiring professional personnel to spend considerable time and effort, which not only increases the company's operating costs but also forces the production line to stop during filter element replacement, thereby reducing production efficiency. Furthermore, the complex replacement process also increases the risk of equipment damage due to improper operation. To address these issues, this utility model adopts a fixed installation method... The hook mechanism solves the problem by allowing workers to easily install filter modules. The filter module's side groove is aligned with the mounting frame and slid in. When the curved section contacts the pressure rod, it pushes the track component. Due to the varying depths of the track at the top, the track component can only slide clockwise. The hook engages with the recessed section of the track near the pressure rod, causing the inverted U-shaped frame to move with the track component. This pushes the sliding rod, causing the fixing hook to rotate clockwise upwards around the base rod, securing the filter module in the fixing slot. When the filter module needs replacement, the worker pushes it inwards, causing the track component to move towards the return spring. The L-shaped hook slides clockwise out to the track near the return spring, releasing the track component and pushing it back to its original position. The fixing hook then rotates counter-clockwise away from the fixing slot, allowing workers to easily disassemble the filter module and improving work efficiency.

[0014] 2. In existing technologies, track components are highly susceptible to external environmental factors, vibration interference from adjacent equipment, and instability caused by manual pushing by operators during operation. These factors combined cause the track components to fail to maintain a constant parallel state relative to their ideal trajectory. This non-parallel movement not only causes additional friction and wear between the track components and their contacting parts, reducing the overall operating efficiency of the equipment, but also accelerates the aging or damage of certain components due to uneven dynamic load distribution. Over time, this unstable movement state leads to a decrease in the operational reliability of the entire system, manifesting as increased mechanical vibration and reduced positioning accuracy. In severe cases, it can even cause equipment failure and shutdown, resulting in unnecessary interruptions and losses to production activities. To address these issues, this utility model employs a method of installing limiting ladder components. By coordinating the limiting ladder components with the limiting ladder groove, the mounting frame maintains a stable movement path, ensuring smooth movement while preventing abnormal wear between components, thereby improving the service life of the equipment.

[0015] 3. In the prior art, during the contact process between the pressure rod and the arc-shaped ladder component, the relatively small contact area leads to a significant increase in pressure at the contact point. If this high-pressure state continues for a long time, the surface of the arc-shaped ladder component will gradually be eroded and worn. As time goes by and the frequency of use increases, this wear phenomenon of the arc-shaped ladder component will become more and more serious, thus affecting the normal operation and service life of the entire equipment. Wear not only leads to a decline in equipment performance, but also triggers a chain reaction in other components, ultimately causing overall equipment failure or premature scrapping. To address this problem, this utility model adopts the method of installing pressure pads to solve it. By using pressure pads, the contact area between the pressure rod and the arc-shaped ladder component is greatly increased, thereby reducing the pressure at the contact area, preventing damage to the arc-shaped ladder component, and achieving the effect of improving the service life of the equipment.

[0024] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0027] Reference Figure 1-6A cascade ultra-low dew point freeze dryer includes a freeze-drying equipment body 1. A filter 101 is fixed to the inner wall of the freeze-drying equipment body 1. A filter element module 102 is provided on the inner wall of the filter 101. Hook grooves 2 are opened on both sides of the inner wall of the filter 101. An installation frame 201 is fixed to the top of the hook grooves 2. A pressure rod 202 is slidably connected to the inner wall of the installation frame 201. A track component 203 is fixed to one end of the pressure rod 202. A return spring 204 is fixed to one end of the track component 203. One end of the return spring 204 is fixed to the inner wall of the installation frame 201. An L-shaped hook rail component 205 is rotatably connected to the top of the installation frame 201. One end of the circumference is slidably connected to the inner wall of the top track of the track component 203. The bottom of the track component 203 is fixed with an inverted U-shaped frame rail frame 206. The inner wall of the inverted U-shaped frame rail frame 206 is slidably connected with a sliding groove rod 207. The circumference of the sliding groove rod 207 is fixed with a fixing hook 208. Both sides of the fixing hook 208 are fixed with a rotating base rod 209. One end of the rotating base rod 209 is rotatably connected with a swivel member 2010. The top of the swivel member 2010 is fixed to the bottom of the mounting frame 201. A side bottom groove 2011 is opened on one side of the bottom of the filter element module 102. An arc-shaped step member 2012 is fixed on the inner wall of the side bottom groove 2011. A fixing rectangular groove 2013 is opened at the bottom of the arc-shaped step member 2012. Both sides of the inner wall of the mounting frame 201 are provided with limiting ladder grooves 3, and both sides of the track component 203 are fixed with limiting ladder components 301. The surface of the limiting ladder component 301 is slidably connected to the inner wall of the limiting ladder groove 3. During operation, the track component 203 is easily affected by external environmental factors, vibration interference from adjacent equipment, and instability caused by manual pushing by the operator. These factors combined can cause the track component 203 to fail to maintain a constant parallel state relative to its ideal trajectory during movement. This non-parallel movement not only causes additional friction and wear between the track component 203 and its contacting components, but also reduces the overall operating performance of the equipment. In addition to improving efficiency, uneven dynamic load distribution can accelerate the aging or damage of certain components. Over time, this unstable motion state can lead to a decrease in the reliability of the entire system, manifested as increased mechanical vibration and reduced positioning accuracy. In severe cases, it can even cause equipment failure and shutdown, resulting in unnecessary interruptions and losses to production activities. This problem is solved by installing a limiting ladder component 301. Through the cooperation between the limiting ladder component 301 and the limiting ladder groove 3, the mounting frame 201 can always maintain a stable motion path. While maintaining smooth movement, it prevents abnormal wear between components, thereby improving the service life of the equipment.

[0028] One end of the pressure rod 202 is fixed with a pressure pad 4. During the contact process between the pressure rod 202 and the arc-shaped ladder component 2012, the relatively small contact area leads to a significant increase in pressure at the contact point. If this high-pressure state continues for a long time, the surface of the arc-shaped ladder component 2012 will gradually be eroded and worn. With the passage of time and the increase in usage frequency, this wear phenomenon of the arc-shaped ladder component 2012 will become more and more serious, thus affecting the normal operation and service life of the entire equipment. Wear not only leads to a decline in equipment performance but also triggers a chain reaction in other components, ultimately causing overall equipment failure or premature scrapping. The installation of the pressure pad 4 solves this problem by greatly increasing the contact area between the pressure rod 202 and the arc-shaped ladder component 2012, thereby reducing the pressure at the contact area and preventing damage to the arc-shaped ladder component 2012, thus improving the service life of the equipment. Both ends of the inner wall of the limiting ladder groove 3 are glued and fixed with groove end pads 5, which prevents collision wear between components and improves the service life of the equipment. The bottom arc surface of the 2012 curved ladder component has a hand grip groove 6, which facilitates operation by staff and improves user experience. Reinforcing ribs 7 are fixed to the sides of the freeze-drying equipment body 1, which strengthens the stability of the equipment shell and extends its service life. Edge-binding curved ribs 8 are fixed to the edges of the freeze-drying equipment body 1, which reduces wear and tear on components during transportation and further extends the equipment's service life.

[0029] The working principle of this utility model is as follows: When the operator needs to install the filter element module 102, the side bottom groove 2011 of the filter element module 102 is aligned with the mounting frame 201 and slid in. When the arc-shaped step member 2012 contacts the pressure rod 202, it pushes the track member 203. Due to the different depths in the track at the top of the track member 203, the track member 203 can only slide clockwise. The hook is engaged with the track recess on the side of the track member 203 near the pressure rod 202. The inverted U-shaped frame rail bracket 206 moves together with the track member 203, pushing the sliding rod 207 to make the fixing hook 208 rotate. The rod 209 rotates clockwise upwards around the axis, hooking the fixing groove 2013 to fix the filter module 102. When the staff needs to replace the filter module 102, they push the filter module 102 inwards, causing the track component 203 to move towards the end of the return spring 204 again. The L-shaped hook track component 205 slides clockwise out to the track near the end of the return spring 204. The track component 203 loses its fixing position, and the return spring 204 pushes it out to reset. The fixing hook 208 rotates counterclockwise away from the fixing groove 2013, thus allowing the staff to easily disassemble the filter module 102.
