Description

Technical Field

[0001] This application relates to the field of physical dehydration equipment, and more particularly to a dehydration press. Background Technology

[0002] With the advancement and development of food preservation technology, in order to improve the shelf life and taste of food, food usually needs to be dehydrated after harvesting, depending on its intended use and method of consumption.

[0003] For example, freshly picked bamboo shoots have a water content as high as 80%-90%. If they are not processed in time, the high moisture content can easily lead to the growth of microorganisms and cause the bamboo shoots to rot. Therefore, after the bamboo shoots have undergone preliminary processing, they need to be further dehydrated by physical dehydration devices to form dried bamboo shoots.

[0004] Among them, Chinese utility model patent, publication (announcement) number: CN221410335U, discloses a dehydration device for bamboo shoot processing, including an outer cylinder and an inner cylinder, both of which are equipped with connecting components. The inner cylinder is equipped with an anti-detachment component. This utility model allows bamboo shoots to be dehydrated to be placed inside the inner cylinder. By pulling a protrusion, an arc-shaped limiting block is moved into an arc-shaped groove. A connecting block set on the lower surface of the inner cylinder can be inserted into the connecting port. By rotating the rotating ring, the connecting groove is aligned with the rectangular block, and the rectangular block is placed into the connecting groove. After releasing the protrusion, the arc-shaped limiting block can enter the limiting groove by the force of the arc-shaped spring, connecting the inner cylinder and the rotating ring. When dehydration is completed and the bamboo shoots need to be removed from the inner wall, the protrusion can be moved to disengage the arc-shaped limiting block from the limiting groove. The inner cylinder can be removed from the outer cylinder through the through hole, and the bamboo shoots inside can be removed, thus achieving the purpose of dehydrating bamboo shoots. The operation is simple and conducive to promotion and application.

[0005] However, in practical applications, although bamboo shoots have been softened and partially dehydrated during the initial processing, bamboo shoots are mainly composed of water and dietary fiber. Even with centrifugal dehydration, a large amount of water will still remain. In subsequent processing steps, a second dehydration is required, and the dehydration cycle is relatively long, indicating room for improvement. Utility Model Content

[0006] The purpose of this utility model is to provide a dehydration press to improve the convenience and efficiency of the bamboo shoot dehydration process.

[0007] To achieve the above objectives, the water-squeezing press provided in this application adopts the following technical solution:

[0008] A dewatering press includes a main frame with a closed door that slides along its height. A transverse discharge assembly is located on the side of the main frame away from the closed door. The main frame, through the closed door and the transverse discharge assembly, forms a material cavity. Several drainage holes are formed through the surface of the main frame and the surface of the closed door along their thickness. A longitudinal dewatering assembly is located on the main frame above the material cavity. The longitudinal dewatering assembly moves along the main frame towards or away from the material cavity. When the longitudinal dewatering assembly moves away from the material cavity, the closed door moves along the main frame toward the longitudinal dewatering assembly, at which point the material cavity is in an open state.

[0009] Preferably, the main frame is provided with a guide groove along the height direction, and the closing door is slidably disposed in the guide groove.

[0010] Preferably, the main frame is provided with a feeding port.

[0011] Preferably, a water-blocking baffle is provided on the surface of the main frame, and the water-blocking baffle and the surface of the main frame form a flow gap along the height direction of the main frame.

[0012] Preferably, the longitudinal dewatering assembly includes a first pressure plate and a first hydraulic cylinder, the first hydraulic cylinder being mounted on the main frame, and the piston rod of the first hydraulic cylinder movably passing through the main frame and being fixedly connected to the first pressure plate.

[0013] Preferably, a hydraulic push rod is provided on the main frame, the base of the hydraulic push rod is hinged to the main frame, and the output shaft of the hydraulic push rod is connected to the closed door.

[0014] Preferably, a water collection tank is provided below the main frame.

[0015] Preferably, the main frame is provided with a plurality of reinforcing ribs, which are arranged in a crisscross pattern along the surface of the main frame.

[0016] Compared with the prior art, the present invention provides a dewatering press, which has the following advantages:

[0017] 1. The bamboo shoots are placed in the material chamber to increase the single processing capacity of bamboo shoot dehydration. The longitudinal squeezing component applies pressure to the bamboo shoots in the material chamber to dehydrate them. The water removed from the bamboo shoots is discharged through the drain hole. After the bamboo shoots are dehydrated, the longitudinal squeezing component moves away from the material chamber. At this time, the closed door opens and the dehydrated bamboo shoots in the material chamber are pushed out along the main frame by the transverse discharge component. This achieves the purpose of rapid dehydration of bamboo shoots. The operation is simple and the stability is high. It plays a positive guiding role in reducing the water content of the dehydrated bamboo shoots.

[0018] 2. Water is blocked by a baffle to prevent splashing of water flowing out of the drain hole, allowing the water to flow out through the flow gap for easy collection.

[0019] 3. The guide groove limits the sliding path of the closed door along the main frame and increases the supporting force of the closed door, so as to avoid the closed door being subjected to excessive force when the material in the material cavity is squeezed by the longitudinal squeezing component, which could cause the closed door to fall off along the main frame.

[0024] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0025] This application discloses a water-squeezing press. (Refer to...) Figure 1 and Figure 2 A dewatering press includes a main frame 1. A closed door 2 is slidably disposed on the main frame 1 along the height direction. A transverse discharge assembly 3 is disposed on the side of the main frame 1 away from the closed door 2. The main frame 1 forms a material cavity 4 by enclosing the closed door 2 and the transverse discharge assembly 3. Several drainage holes 5 are respectively opened through the surface of the main frame 1 and the surface of the closed door 2 along the thickness direction. A longitudinal dewatering assembly 6 is disposed on the main frame 1 above the material cavity 4. The longitudinal dewatering assembly 6 moves along the main frame 1 towards or away from the material cavity 4. When the longitudinal dewatering assembly 6 moves away from the material cavity 4, the closed door 2 moves along the main frame 1 towards the longitudinal dewatering assembly 6. At this time, the material cavity 4 is in an open state.

[0026] Specifically, the outer contour of the main frame 1 is arranged in a square shape, and the main frame 1 is provided with several reinforcing ribs 13. The reinforcing ribs 13 are arranged in a cross pattern along the surface of the main frame 1. The reinforcing ribs 13 can be fixedly connected to the main frame 1 by welding to improve the load-bearing capacity and rigidity of the main frame 1.

[0027] Furthermore, refer to Figure 1 and Figure 3 The main frame 1 is provided with a guide groove 7 along the height direction, and the closing door 2 is slidably disposed in the guide groove 7.

[0028] Specifically, limit plates 14 are installed on the side walls of the main frame 1 along the length of the closed door 2. The cross-sectional profile of the limit plates 14 is L-shaped and is fixedly connected to the main frame 1 by welding. A guide groove 7 is formed between the limit plates 14 and the main frame 1. The groove width of the guide groove 7 is in clearance fit with the thickness tolerance of the closed door 2, so that the closed door 2 can slide smoothly along the height direction of the main frame 1 through the guiding action of the guide groove 7, thereby improving the stability of the closed door 2 when sliding along the main frame 1.

[0029] Correspondingly, a hydraulic push rod 11 is provided on the main frame 1. The base of the hydraulic push rod 11 is hinged to the main frame 1, and the output shaft of the hydraulic push rod 11 is connected to the closed door 2. There are two hydraulic push rods 11, which are located on the main frame 1 at both ends of the closed door 2 along its length. Since the connection relationship between the two hydraulic push rods 11 and the main frame 1 and the closed door 2 is the same, the connection relationship between one of the hydraulic push rods 11 and the main frame 1 and the closed door 2 will be described in detail below.

[0030] The bottom of the main frame 1 protrudes along the side wall to form a hinge seat 15. The base of the hydraulic push rod 11 is hinged to the hinge seat 15 through a pin, so that the hydraulic push rod 11 can swing along the main frame 1.

[0031] Therefore, when it is necessary to drive the closed door 2 to move towards the longitudinal squeezing assembly 6, the output shaft of the hydraulic push rod 11 extends, thereby driving the closed door 2 to slide along the guide groove 7. During the extension of the output shaft of the hydraulic push rod 11, due to the clearance fit between the thickness of the closed door 2 and the width tolerance of the guide groove 7, the closed door 2 will swing along the main frame 1 during its movement towards the longitudinal squeezing assembly 6. At the same time, the base of the hydraulic push rod 11 and the hinge seat 15 are in a hinged state, thereby correcting the movement path of the closed door 2 along the main frame 1. This reduces the probability that the closed door 2 will not move smoothly along the guide groove 7 due to the angular deviation of the movement path of the closed door 2 along the main frame 1, which would cause mechanical friction between the closed door 2 and the surface of the limiting plate 14.

[0032] In addition, since several drainage holes 5 are provided through the surface of the main frame 1 and the surface of the closed door 2 along the thickness direction, for ease of explanation, the drainage holes 5 located on the main frame 1 will be described in detail.

[0033] The drainage hole 5 can be circular or polygonal. In this embodiment, preferably, to facilitate the processing and shaping of the drainage hole 5 and improve its drainage capacity, thereby reducing the possibility of the bamboo shoot overflowing along the drainage hole 5 and causing blockage during the squeezing process, the drainage hole 5 is preferably a waist-shaped groove. Several drainage holes 5 are evenly distributed along the surface of the main frame 1, so that the drainage capacity is the same at all points on the surface of the main frame 1.

[0034] Reference Figure 1 and Figure 2 A water-blocking baffle 9 is provided on the surface of the main frame 1, and a flow gap 10 is formed between the water-blocking baffle 9 and the surface of the main frame 1 along the height direction of the main frame 1.

[0035] First, it should be noted that in this embodiment, water-blocking baffles 9 are respectively installed on the surface of the main frame 1 and the surface of the closed door 2. Since the water-blocking baffle 9 located at the closed door 2 and the water-blocking baffle 9 located on the surface of the main frame 1 have the same cooperation method, the following description will focus on the cooperation relationship between the main frame 1 and the water-blocking baffle 9.

[0036] The water-blocking baffle 9 is connected to the main frame 1 via a hinge structure, which allows the water-blocking baffle 9 to open or close along the main frame 1, so as to facilitate cleaning of the water-blocking baffle 9 and the main frame 1.

[0037] During the process of squeezing the bamboo shoots located in the material cavity 4 by the longitudinal water squeezing component 6, the water that is separated from the bamboo shoots is discharged through the drain hole 5. The water blocking baffle 9 blocks the water discharged through the drain hole 5 to prevent the water discharged through the drain hole 5 from splashing.

[0038] Meanwhile, the end of the water-blocking baffle 9 facing the bottom of the main frame 1 is open. As a result, the water discharged along the drain hole 5 is blocked by the water-blocking baffle 9 and flows along the flow gap 10. The water flows towards the open end of the water-blocking baffle 9 by its own gravity, thus realizing the drainage operation.

[0039] In other embodiments, a water collection tank is provided below the main frame 1 to collect water discharged along the flow gap 10 for unified treatment.

[0040] Reference Figure 1 and Figure 2The transverse discharge assembly 3 includes a second pressure plate 31 and a second hydraulic cylinder 32. The second hydraulic cylinder 32 is located on the side of the main frame 1 away from the closing door 2. The second hydraulic cylinder 32 is installed on the main frame 1 in the horizontal direction. The piston rod of the second hydraulic cylinder 32 moves through the main frame 1 and is fixedly connected to the second pressure plate 31. When the piston rod of the second hydraulic cylinder 32 moves, the piston rod of the second hydraulic cylinder 32 will drive the second pressure plate 31 to move toward the closing door 2.

[0041] Furthermore, the length of the second pressure plate 31 is in a clearance fit with the length tolerance of the material cavity 4, so that the second pressure plate 31 can move smoothly along the material cavity 4.

[0042] Meanwhile, the main frame 1 is provided with a feeding port 8, which is located on the main frame 1 at the second pressure plate 31. The feeding port 8 is set downward from the end away from the main frame 1 to the end closer to the main frame 1. The bamboo shoot can be quickly fed into the material cavity 4 through the feeding port 8.

[0043] Reference Figure 1 and Figure 2 The longitudinal dewatering assembly 6 includes a first pressure plate 61 and a first hydraulic cylinder 62. The first hydraulic cylinder 62 is mounted on the main frame 1, and the piston rod of the first hydraulic cylinder 62 moves through the main frame 1 and is fixedly connected to the first pressure plate 61.

[0044] When the piston rod of the first hydraulic cylinder 62 moves, the first pressure plate 61 will move synchronously with the piston rod of the first hydraulic cylinder 62 to drive the first pressure plate 61 into the material cavity 4.

[0045] On the other hand, in this embodiment, the main frame 1, the first pressure plate 61, the second pressure plate 31, the water-blocking baffle 9, and the closing door 2 are all made of stainless steel to improve corrosion resistance.

[0046] The implementation principle of the dewatering press according to this application embodiment is as follows: In actual application, bamboo shoots are fed into the material cavity 4 through the feeding port 8, and the first hydraulic cylinder 62 is activated. At this time, the piston rod of the first hydraulic cylinder 62 will drive the first pressure plate 61 to move into the material cavity 4. At the moment when the first pressure plate 61 contacts the bamboo shoot, it will begin to apply continuous and slow pressure to the bamboo shoot located in the material cavity 4. Under the pressure, the bamboo shoot will begin to dewater, and the water that is separated from the bamboo shoot will be discharged through the drain hole 5. The water discharged through the drain hole 5 is blocked by the water-blocking baffle 9, causing the water to flow along the flow gap 10 and along the water-blocking baffle 9. The water flows out from one open end to avoid splashing of water discharged along the drain hole 5. After the bamboo shoots are squeezed and dehydrated, the piston rod of the first hydraulic cylinder 62 begins to retract, and drives the first pressure plate 61 to move synchronously with the piston rod of the first hydraulic cylinder 62. Then the output shaft of the hydraulic push rod 11 extends to drive the closed door 2 to move toward the first pressure plate 61, so that the material cavity 4 opens. The piston rod of the second hydraulic cylinder 32 moves to drive the second pressure plate 31 to move toward the closed door 2, thereby achieving the purpose of pushing the dehydrated bamboo shoots located in the material cavity 4 out along the material cavity 4, and improving the production efficiency of bamboo shoot dehydration processing.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
