Description

Technical Field

[0001] This utility model relates to the field of foaming tank technology, specifically a negative pressure low-temperature foaming tank. Background Technology

[0002] A fermentation tank is a closed pressure vessel used for short-term extraction, leaching, or fermentation of plant, animal, or mineral raw materials under negative pressure and low temperature. The tank typically maintains a vacuum of -0.04 MPa to -0.09 MPa and a low temperature of 0°C to 10°C to inhibit oxidation, reduce aroma volatilization, and accelerate the dissolution of active ingredients. This equipment is widely used in the food industry for preparing concentrated herbal teas and health wine bases, in the pharmaceutical industry for low-temperature extraction of traditional Chinese medicine, and in the cosmetics industry for the leaching of natural essential oils. It requires complete discharge and rapid switching of raw materials after each batch processing to meet the demands of continuous and clean production.

[0003] Existing foaming tanks generally adopt a fixed tank body + top manual flange cover + side discharge valve structure. The following technical problems have been exposed during use: the tank cover and the discharge valve are two independent mechanisms, with many parts and sealing points. Frost and adhesion at low temperatures make it difficult to open the cover; the side discharge port angle is fixed, and viscous or solid-containing extracts are prone to forming dead corners at the bottom of the tank, resulting in incomplete discharge and batch cross-contamination; the single-cylinder hinged structure added to achieve tilting discharge can only provide a single tilting action, and additional power is still required to open the tank cover. The overall footprint is large and the center of gravity is offset. After long-term use, the negative pressure sealing surface is deformed by bending moment, and the vacuum leakage rate increases. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a negative pressure low-temperature brewing tank, which has advantages such as facilitating negative pressure low-temperature brewing and material discharge. It solves the problems of existing technologies where the tank lid and discharge valve are two separate mechanisms, resulting in many parts and sealing points, and difficulty in opening the lid due to frost adhesion at low temperatures; the fixed angle of the lateral discharge port makes it easy for viscous or solid-containing extracts to form dead corners at the bottom of the tank, leading to incomplete discharge and batch cross-contamination; the single-cylinder hinged structure added to achieve tilting discharge can only provide a single tilting action, still requiring additional power to open the tank lid, and the overall footprint is large and the center of gravity is offset. After long-term use, the negative pressure sealing surface is deformed by bending moment, and the vacuum leakage rate increases.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure low-temperature foaming tank, comprising a support base and a support mechanism disposed on the top of the support base;

[0006] The support mechanism includes two sets of fixed seats fixedly installed on the top of the support base. A support shaft is fixedly connected inside each of the two sets of fixed seats. A lifting frame is rotatably connected to the outside of the two sets of support shafts. A tank is embedded inside the lifting frame. Two sets of first hydraulic cylinders are rotatably connected to the inner bottom wall of the support base. The output ends of the two sets of first hydraulic cylinders are respectively connected to the front and rear sides of the bottom of the lifting frame. Columns are fixed to the front and rear sides of the support base. Second hydraulic cylinders are fixedly connected to the outside of the two sets of columns. A lifting plate is fixedly connected to the output shaft of the two sets of second hydraulic cylinders. A tilting arm is rotatably connected to the outside of the lifting plate. A tank cover is fixedly connected to one side of the lifting plate by the tilting arm. A negative pressure component is provided on the outside of the tank cover.

[0007] The support mechanism also includes a third hydraulic cylinder disposed on the inner bottom wall of the support base. The output shaft of the third hydraulic cylinder is attached to the bottom of the lifting frame to assist in the lifting of the lifting frame. A fourth hydraulic cylinder is disposed at the bottom of the lifting plate, and the output shaft of the fourth hydraulic cylinder is rotatably connected to the tilting arm.

[0008] Furthermore, a controller is fixed to the front of the support base, and several sets of support feet are provided at the bottom of the support base.

[0009] Furthermore, the negative pressure assembly includes a negative pressure pipe connected to the outside of the can lid, a pressure gauge is provided on the outside of the negative pressure pipe, a refrigeration pipe is connected to the outside of the can lid, and the end of the refrigeration pipe near the can lid passes through and extends into the interior of the can body.

[0010] Furthermore, the cross-sectional shape of the flipping arm is set to L-shape, and the can lid is placed on top of the can body.

[0011] Furthermore, the distance between the two sets of columns on the side closest to each other is greater than the maximum diameter of the tank, which is used to allow the tank to be tilted over to pour out the internal materials.

[0012] Furthermore, the inside of the lifting frame is provided with an embedding groove that is adapted to the tank body, and the tank body is embedded in the inside of the lifting frame through the embedding groove.

[0013] Furthermore, a pad is provided at the bottom of the lifting frame for fitting against the output shaft of the third hydraulic cylinder.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. This negative pressure low temperature foaming tank, by coordinating the movement of the second hydraulic cylinder, lifting plate, and tilting arm in the tank lid opening and closing mechanism with the first hydraulic cylinder, lifting frame, and third hydraulic cylinder in the tank tilting mechanism, and integrating them on the same support base, significantly reduces the number of parts and sealing points, avoids the difficulty of opening the lid caused by low temperature frost, and realizes the automatic opening of the tank lid and the tilting of the tank for material discharge under negative pressure low temperature environment with a single power synchronous operation.

[0016] 2. This negative pressure low-temperature foaming tank utilizes three sets of hydraulic cylinders arranged at multiple angles in space, allowing the tank to stop at any angle within a certain range and tilt slowly. Combined with the embedded tank design of the lifting frame, dead corners at the bottom of the tank are eliminated, ensuring the complete discharge of viscous or solid materials. At the same time, the symmetrical support of the hydraulic cylinders ensures that the center of gravity always falls on the center line of the support base, avoiding bending deformation of the negative pressure sealing surface.

[0023] 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.

[0024] Please see Figure 1-5The negative pressure low temperature foaming tank in this embodiment includes a support base 1 and a support mechanism 2 disposed on the top of the support base 1.

[0025] In this embodiment, the support mechanism 2 includes two sets of fixed seats 21 fixedly installed on the top of the support base 1. The interior of each set of fixed seats 21 is fixedly connected to a support shaft 22. The outer sides of the two sets of support shafts 22 are rotatably connected to a lifting frame 23. The interior of the lifting frame 23 is embedded with a tank body 24. The inner bottom wall of the support base 1 is rotatably connected to two sets of first hydraulic cylinders 25. The output ends of the two sets of first hydraulic cylinders 25 are respectively connected to the front and rear sides of the bottom of the lifting frame 23. The front and rear sides of the support base 1 are fixedly connected to columns 26. The outer sides of the two sets of columns 26 are fixedly connected to second hydraulic cylinders 27. The output shafts of the two sets of second hydraulic cylinders 27 are fixedly connected to a lifting plate 28. The outer side of the lifting plate 28 is rotatably connected to a tilting arm 29. The tilting arm 29 is fixedly connected to a tank cover 210 on one side of the lifting plate 28. A negative pressure component 3 is provided on the outer side of the tank cover 210.

[0026] It should be noted that the brewing process in tank 24 is as follows: the brewing solution and raw materials are poured into the interior of tank 24, and when all cylinders are in their original positions, tank 24 is... Figure 1 The tank is tilted as shown, and then the lid 210 is closed. The external negative pressure system is connected through the negative pressure pipe 31 to draw the tank 24 to a suitable negative pressure environment. Then, the cooling pipe 32 is connected to the external cooler. The external cooler generates cold air and introduces it into the tank 24 through the cooling pipe 32 to achieve cooling and maintain the subsequent low temperature state.

[0027] It should also be noted that when the material is unloaded after the brewing process is completed, the controller first commands the fourth hydraulic cylinder 212 to retract, which drives the tilting arm 29 to rotate downward around the lifting plate 28, thereby completely separating the can cover 210 from the can body 24 and moving it horizontally outward to avoid subsequent interference.

[0028] In this embodiment, the support mechanism 2 also includes a third hydraulic cylinder 211 disposed on the inner bottom wall of the support base 1. The output shaft of the third hydraulic cylinder 211 is attached to the bottom of the lifting frame 23 to assist in the lifting of the lifting frame 23. A fourth hydraulic cylinder 212 is disposed at the bottom of the lifting plate 28. The output shaft of the fourth hydraulic cylinder 212 is rotatably connected to the tilting arm 29.

[0029] In this embodiment, a controller is fixed on the front of the support base 1, and several sets of support feet are provided on the bottom of the support base 1.

[0030] In this embodiment, the negative pressure component 3 includes a negative pressure pipe 31 connected to the outside of the can lid 210, a pressure gauge is provided on the outside of the negative pressure pipe 31, and a refrigeration pipe 32 is connected to the outside of the can lid 210. The end of the refrigeration pipe 32 near the can lid 210 passes through and extends into the interior of the can body 24.

[0031] In this embodiment, the cross-sectional shape of the flipping arm 29 is set to L-shape, and the can lid 210 is placed on the top of the can body 24.

[0032] In this embodiment, the distance between the two sets of columns 26 on one side is greater than the maximum diameter of the tank 24, which is used to allow the tank 24 to be tilted to pour out the internal material.

[0033] In this embodiment, the inside of the lifting frame 23 is provided with an embedding groove that is adapted to the tank 24, and the tank 24 is embedded in the inside of the lifting frame 23 through the embedding groove.

[0034] In this embodiment, a pad is provided at the bottom of the lifting frame 23 for fitting with the output shaft of the third hydraulic cylinder 211.

[0035] Specifically, the third hydraulic cylinder 211 first extends and lifts the tail of the lifting frame 23 through the pad block, so that it is raised to a certain height around the support shaft 22; at this time, the angle between the lifting frame 23 and the first hydraulic cylinder 25 changes from an acute angle to an obtuse angle to avoid subsequent dead points.

[0036] The working principle of the above embodiments is as follows:

[0037] The tank body 24 is fixed in the lifting frame 23 by an embedded groove. With the tank lid 210 closed, it is connected to an external negative pressure system via a negative pressure pipe 31 in the negative pressure assembly 3. The negative pressure pipe 31 acts as a medium to evacuate the inside of the tank body 24 to a certain negative pressure condition. Simultaneously, the refrigeration pipe 32 delivers a cold source into the tank, allowing the material to complete the soaking process in a low-temperature environment of 0-10℃. When the material is discharged after soaking, the controller first commands the fourth hydraulic cylinder 212 to retract, driving the tilting arm 29 to rotate downwards around the lifting plate 28, thereby completely separating the tank lid 210 from the tank body 24 and moving it horizontally outwards to avoid subsequent interference. Furthermore, the... The second hydraulic cylinder 27 extends, driving the lifting plate 28, along with the tilting arm 29 and the tank cover 210, to rise vertically along the column 26, creating upper space for the tank body 24 to tilt. Then, the third hydraulic cylinder 211 extends first, using the pads to lift the tail of the lifting frame 23, raising it to a certain height around the support shaft 22. At this time, the acute angle between the lifting frame 23 and the first hydraulic cylinder 25 changes to an obtuse angle to avoid subsequent dead points. Finally, the first hydraulic cylinder 25 continues to extend, driving the lifting frame 23 to rotate the tank body 24 around the support shaft 22 by a certain angle. The material is then completely discharged along the tank wall into the pre-placed container.
