Description

Technical Field

[0001] This utility model relates to the field of freeze-drying equipment technology, and in particular to a freeze-drying equipment equipped with an intermittent feeding structure. Background Technology

[0002] In the existing field of freeze-drying equipment, with the increasing demands for equipment stability and production efficiency in industrial production, equipment maintenance and repair have become crucial to ensuring smooth production. Currently, the connection between the feeding structure and the machine body of most freeze-drying equipment is relatively complex, typically employing traditional methods such as bolt fastening and welding.

[0003] During long-term operation, the feeding structure, such as the feed chute and the transmission components that drive the feed, is prone to failure due to material wear, corrosion, or frequent mechanical movement. Once a failure occurs, traditional connection methods limit the time and effort required for maintenance personnel to disassemble the relevant components. For example, bolted connections require unscrewing multiple bolts individually, which is not only cumbersome but also prone to problems like rust and stripped threads, making disassembly difficult. Welded connections are even more troublesome, requiring specialized cutting tools to cut open the welded areas, and then re-welding during reinstallation. This increases maintenance difficulty and time costs, and may damage other components. Furthermore, regular cleaning of the feeding structure is necessary to ensure cleanliness and prevent hygiene problems and equipment malfunctions caused by material residue. The complex connection methods make cleaning extremely difficult, making it hard to thoroughly clean every corner, thus affecting the overall performance and lifespan of the equipment.

[0004] Furthermore, some freeze-drying equipment on the market currently suffers from significant defects in its feeding methods. Some equipment uses continuous feeding, with materials constantly entering the freeze-drying machine. This easily leads to material accumulation within the machine, preventing some materials from fully contacting the freeze-drying environment and causing uneven drying. For example, in food freeze-drying, uneven drying can cause some foods to lose their texture and nutritional value due to over-drying, while others may spoil easily due to under-drying, severely affecting product quality and shelf life. Other equipment, while attempting intermittent feeding, lacks precise control methods, making it impossible to accurately set the feeding interval and quantity. Too long a feeding interval increases equipment downtime and reduces production efficiency; too short a feeding interval leads to problems similar to continuous feeding, compromising drying quality. Moreover, unstable feeding quantities make it difficult to precisely control parameters such as temperature and pressure during freeze-drying, further affecting the drying effect. Therefore, we provide a freeze-drying device equipped with an intermittent feeding structure. Utility Model Content

[0005] To address the aforementioned problems, this invention proposes a freeze-drying device equipped with an intermittent feeding structure, which more accurately solves the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution:

[0007] The utility model proposes a freeze-drying device equipped with an intermittent feeding structure, including a freeze-drying body and an arc-shaped column. The arc-shaped column is slidably inserted into the freeze-drying body, and a material-holding trough is formed on the surface of the arc-shaped column. An intermittent propulsion structure is connected between the freeze-drying body and the material-holding trough for intermittent feeding.

[0008] The intermittent propulsion structure includes a fixed plate fixedly installed on the periphery of the end of the arc-shaped column and a hydraulic cylinder fixedly installed on the freeze dryer body. The output end of the hydraulic cylinder is fixedly welded with a connecting plate. The surface of the freeze dryer body is respectively equipped with a controller and a timer for controlling the intermittent start of the hydraulic cylinder.

[0009] A disassembly assembly is connected between the fixing plate and the connecting plate.

[0010] Furthermore, the assembly and disassembly assembly includes an opening groove on the surface of the fixed plate and a rectangular slide groove on the surface of the connecting plate. The end wall of the opening groove has a limit insertion hole. A sliding plate is slidably connected to the inner wall of the rectangular slide groove. A limit insertion rod is fixedly connected to the surface of the sliding plate. A reciprocating component is connected between the rectangular slide groove and the sliding plate.

[0011] Furthermore, the reciprocating component includes a strip-shaped mounting groove formed on the inner sidewall of a rectangular slide groove. A horizontal fixing rod is fixedly connected between the two end walls of the strip-shaped mounting groove. A spring is sleeved around the horizontal fixing rod, and a movable sleeve block is slidably connected around the horizontal fixing rod.

[0012] Furthermore, the connecting plate is disposed on the inner wall of the opening groove, and one end of the limiting rod passes through the end wall of the rectangular slide groove and is inserted into the inner wall of the limiting hole. The inner diameter of the limiting hole is adapted to the outer diameter of the limiting rod.

[0013] Furthermore, the movable sleeve is slidably connected to the inner wall of the strip-shaped placement groove, and the opposite surfaces of the two movable sleeves are fixedly connected to the two end surfaces of a sliding plate.

[0014] Furthermore, one end of the spring is fixedly connected to the end wall of the strip-shaped mounting groove, and the other end of the spring is fixedly connected to one end surface of the movable sleeve block.

[0015] The beneficial effects of this utility model are:

[0016] This invention utilizes a disassembly and assembly assembly between a fixed plate and a connecting plate, employing the cooperation of a limiting rod and a limiting hole, along with springs and moving blocks in the reciprocating component, to achieve rapid connection and disassembly. During daily operation, if the arc-shaped column malfunctions or the material trough needs cleaning or maintenance, workers can easily remove the arc-shaped column from the freeze dryer without complex tools. Simply operate the reciprocating component to pull the limiting rod out of the limiting hole. After maintenance or cleaning, re-operate the reciprocating component to insert the limiting rod back into the limiting hole to complete installation. This convenient disassembly and assembly method significantly reduces equipment maintenance and repair time, minimizes production losses due to downtime, lowers maintenance costs, and improves overall equipment efficiency and economic benefits.

[0017] This invention uses a controller and timer to control the intermittent activation of a hydraulic cylinder, thereby driving an arc-shaped column to achieve intermittent feeding. The timer can precisely set the time interval, and the controller accurately controls the movement of the hydraulic cylinder according to the setting, enabling the arc-shaped column to feed the material in the hopper into the freeze dryer at predetermined time intervals. This precise intermittent feeding method avoids the problem of material accumulation and uneven drying caused by a large influx of material into the freeze dryer at once. The material can enter the freeze dryer in an orderly and uniform manner, and freeze-dry under suitable conditions, ensuring that each material particle can fully contact the freeze-drying environment, thereby improving the quality of freeze-drying, making the quality of the dried material more stable, and meeting the product quality requirements of different production needs.

Detailed Implementation

[0023] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0024] Example

[0025] like Figures 1-4 As shown in the figure, an embodiment of the present invention discloses a freeze-drying device equipped with an intermittent feeding structure, mainly composed of a freeze-drying body 1 and an arc-shaped column 2. The arc-shaped column 2 is connected to the freeze-drying body 1 by a sliding insertion method, ensuring that the arc-shaped column 2 can slide relative to the freeze-drying body 1. A material holding trough 3 is opened on the surface of the arc-shaped column 2 for holding the material to be freeze-dried; to achieve intermittent feeding, an intermittent propulsion structure is connected between the freeze-drying body 1 and the material holding trough 3. The intermittent propulsion structure specifically includes a fixing plate 4 fixedly installed on the periphery of the end of the arc-shaped column 2, and a hydraulic cylinder 5 fixedly installed on the freeze-drying body 1. A connecting plate 6 is fixedly welded to the output end of the hydraulic cylinder 5, and the connecting plate 6 is moved by the extension and retraction of the hydraulic cylinder 5. A controller 7 and a timer 8 are respectively installed on the surface of the freeze-drying body 1. The controller 7 is electrically connected to the hydraulic cylinder 5, and the timer 8 is electrically connected to the controller 7. The time interval is set by the timer 8, and the controller 7 controls the intermittent start of the hydraulic cylinder 5 according to the set time interval, thereby pushing the arc-shaped column 2 to achieve intermittent feeding.

[0026] The above structure enables the intermittent feeding function of the freeze-drying equipment, allowing materials to enter the freeze-drying machine 1 at set time intervals for freeze-drying, thereby improving the controllability and efficiency of the freeze-drying process.

[0027] Furthermore, a disassembly assembly is connected between the fixing plate 4 and the connecting plate 6. Specifically, the disassembly assembly includes an opening slot 9 on the surface of the fixing plate 4 and a rectangular sliding groove 11 on the surface of the connecting plate 6. A limiting insertion hole 10 is formed on the end wall of the opening slot 9, and a sliding plate 12 is slidably connected to the inner wall of the rectangular sliding groove 11, allowing the sliding plate 12 to slide horizontally within the rectangular sliding groove 11. A limiting insertion rod 13 is fixedly connected to the surface of the sliding plate 12, and the limiting insertion rod 13 moves as the sliding plate 12 slides. A reciprocating component is connected between the rectangular sliding groove 11 and the sliding plate 12 to realize the reciprocating motion of the sliding plate 12, thereby driving the insertion and removal of the limiting insertion rod 13.

[0028] The assembly and disassembly mechanism allows for easy connection between the arc-shaped column 2 and the connecting plate 6 of the hydraulic cylinder 5. When the arc-shaped column 2 needs to be connected to the connecting plate 6 of the hydraulic cylinder 5, the reciprocating mechanism can be operated to insert the limiting rod 13 into the limiting hole 10, thus connecting the fixing plate 4 and the connecting plate 6. When disassembly is required, the reciprocating mechanism can be operated to pull the limiting rod 13 out of the limiting hole 10, thus separating the two. This facilitates the installation and disassembly of the arc-shaped column 2 and makes the maintenance and repair of the equipment easier.

[0029] Furthermore, the reciprocating component specifically includes a strip-shaped mounting groove 14 formed on the inner wall of the rectangular slide groove 11, which provides installation space for the horizontal fixing rod 15, the spring 16, and the movable sleeve 17. The horizontal fixing rod 15 is fixedly connected between the two end walls of the strip-shaped mounting groove 14, and the horizontal fixing rod 15 guides the sliding of the movable sleeve 17. A spring 16 is sleeved around the horizontal fixing rod 15; the spring 16 is elastic, capable of deforming under force and returning to its original shape after the external force disappears. The movable sleeve 17 is slidably connected around the horizontal fixing rod 15, and the movable sleeve 17 can slide horizontally on the horizontal fixing rod 15.

[0030] When the limiting rod 13 needs to be inserted into the limiting hole 10, an external force pushes the sliding plate 12, causing the moving sleeve 17 to slide on the horizontal fixing rod 15, compressing the spring 16. Once the limiting rod 13 is aligned with the limiting hole 10, the external force is released, the spring 16 returns to its original state, and the moving sleeve 17 slides in the opposite direction, thereby causing the sliding plate 12 and the limiting rod 13 to be inserted into the limiting hole 10. When the limiting rod 13 needs to be removed, an external force is applied again to push the sliding plate 12, compressing the spring 16, and the limiting rod 13 is pulled out of the limiting hole 10. This reciprocating component realizes the reciprocating motion of the limiting rod 13, facilitating the assembly and disassembly of the components.

[0031] Furthermore, the connecting plate 6 is positioned on the inner wall of the opening groove 9 to ensure accurate alignment between the connecting plate 6 and the fixing plate 4. The reciprocating mechanism is operated to allow one end of the limiting rod 13 to pass through the end wall of the rectangular slide groove 11 and be inserted into the inner wall of the limiting hole 10. At this point, the inner diameter of the limiting hole 10 and the outer diameter of the limiting rod 13 are matched, allowing the limiting rod 13 to be tightly inserted into the limiting hole 10, ensuring the connection stability between the fixing plate 4 and the connecting plate 6.

[0032] By setting the connecting plate 6 in the opening slot 9 and accurately inserting the limiting rod 13 into the limiting hole 10, a reliable connection between the fixing plate 4 and the connecting plate 6 is achieved, ensuring that the two will not loosen or separate when the hydraulic cylinder 5 pushes the arc column 2 for intermittent feeding, thus ensuring the normal operation of the equipment.

[0033] Furthermore, the movable sleeve 17 is slidably connected to the inner wall of the strip-shaped mounting groove 14, ensuring that the movable sleeve 17 can slide stably along the length of the strip-shaped mounting groove 14. The opposing surfaces of the two movable sleeves 17 are fixedly connected to the two end surfaces of a sliding plate 12. When the sliding plate 12 is subjected to external force, it will drive the two movable sleeves 17 to slide synchronously on the horizontal fixing rod 15, ensuring the smoothness of the movement of the sliding plate 12.

[0034] By fixing the two movable sleeve blocks 17 to both ends of the sliding plate 12, the sliding plate 12 can remain horizontal during movement without tilting or shaking, thereby ensuring that the limit plug 13 can be accurately inserted into and pulled out of the limit plug hole 10, improving the operational accuracy and reliability of the assembly and disassembly components.

[0035] Furthermore, one end of the spring 16 is fixedly connected to the end wall of the strip-shaped mounting groove 14, and the other end is fixedly connected to one end surface of the movable sleeve 17. When the movable sleeve 17 slides on the horizontal fixing rod 15, the spring 16 is stretched or compressed, generating an elastic force. When the external force disappears, the elastic force of the spring 16 will push the movable sleeve 17 to slide in the opposite direction, thereby resetting the sliding plate 12 and the limiting rod 13.

[0036] By fixing the two ends of the spring 16 to the end wall of the strip-shaped mounting groove 14 and the surface of the movable sleeve 17 respectively, the spring 16 can generate elastic force when the movable sleeve 17 slides, providing power for the reset of the sliding plate 12 and the limiting rod 13, ensuring the normal operation of the assembly and disassembly components, and facilitating the installation and disassembly of the arc-shaped column 2.
