Description

Technical Field

[0001] This utility model relates to the field of vacuum storage tank technology, and in particular to a feeding mechanism for a vacuum storage tank. Background Technology

[0002] In daily life, to prevent items from rotting or spoiling, food, medicine, tea, coffee beans, and other items are often placed in vacuum storage containers. Then, the air inside the vacuum storage container is removed, creating a vacuum state inside, which increases the storage time of the items and also prevents moisture and insects.

[0003] Existing vacuum storage tanks typically have a vacuum valve and a pressure relief valve installed on them. These valves are connected to the internal space of the tank to achieve vacuuming and pressure relief. When unloading materials from the vacuum storage tank, the pressure relief valve is usually opened to release pressure before the material is unloaded. During this unloading process, the inside of the vacuum storage tank remains at atmospheric pressure, which is not conducive to moisture-proof storage of the materials.

[0004] Therefore, this utility model proposes a feeding mechanism for a vacuum storage tank to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a feeding mechanism for a vacuum storage tank, which enables the vacuum storage tank to complete the feeding under vacuum conditions, effectively preventing the material inside the vacuum storage tank from getting damp.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a feeding mechanism for a vacuum storage tank, the innovation of which is: the feeding mechanism includes a receiving tank and a pressure equalization pipe; The vacuum storage tank has a discharge port at its bottom. The receiving tank is located below the vacuum storage tank and is detachably and sealed to the discharge port. A valve is installed at the discharge port to control whether the receiving tank is connected to the vacuum storage tank. One end of the pressure equalization pipe is connected to the vacuum storage tank and the other end is connected to the receiving tank. A pressure equalization valve is installed on the pressure equalization pipe to control its opening and closing. A pressure relief valve is installed on the receiving tank to control whether the inside of the receiving tank is connected to the outside.

[0007] Furthermore, the receiving tank includes a tank body and a tank cover. The tank cover is installed at the discharge port, and the tank body is located below the tank cover and is detachably and sealingly connected to the tank cover via a connecting assembly. A pressure relief valve is installed on the tank cover, and a pressure equalization pipe is connected to the bottom of the tank body.

[0008] Furthermore, the connecting assembly includes a rocker arm and two push rods; The tank cover has a first flange plate at the bottom and a second flange plate at the top of the tank. Two push rods are each installed on opposite sides of the first flange plate via an L-shaped connector. The push rods are located below the first flange plate and are rotatably mounted on the L-shaped connector via a rotating shaft. The two ends of the rocker arm are connected to the two push rods via a connecting bracket and drive the two push rods to rotate between a first position and a second position. When the push rod is in the first position, there is a distance between the push rod and the first flange plate for the second flange plate to enter. When the tank is moved so that the second flange plate enters between the first flange plate and the push rod, and the push rod rotates to the second position, the central axis of the push rod is perpendicular to the second flange plate. The push rod applies an upward pushing force to the second flange plate, so that the second flange plate and the first flange plate fit tightly together.

[0009] Furthermore, a sealing ring is provided between the first flange plate and the second flange plate.

[0010] Furthermore, the tank contains a breathable packaging bag, the opening of which is located below the discharge port.

[0011] Furthermore, the equalizing pipe is a deformable flexible tube.

[0012] Furthermore, the bottom of the tank is equipped with casters for movement.

[0013] Furthermore, the receiving tank is connected to and communicates with the discharge port through a maintenance section. The maintenance section is installed at the bottom of the discharge port, and the receiving tank is installed at the bottom of the maintenance section. The maintenance section has a maintenance port.

[0014] The advantages of this utility model are: The feeding mechanism of this utility model is achieved by installing a pressure relief valve on the receiving tank and connecting the receiving tank to the vacuum storage tank via a pressure equalization pipe equipped with a pressure equalization valve. When feeding material into the vacuum storage tank, the pressure equalization valve is first opened, and the air in the receiving tank enters the vacuum storage tank through the pressure equalization pipe and is discharged outside the vacuum storage tank during vacuuming. The pressure inside the receiving tank changes from atmospheric pressure to a vacuum state consistent with that inside the vacuum storage tank. The pressure equalization valve is then closed, and the valve at the discharge port is opened. The material is fed under the action of gravity. After feeding is completed, the valve at the discharge port is closed, and the pressure relief valve is opened to change the receiving tank from a vacuum state to an atmospheric pressure state. Then, the receiving tank can be opened and the material removed. Throughout the feeding process, the vacuum storage tank is in a vacuum state, effectively preventing the material inside the vacuum storage tank from getting damp.

[0015] The receiving tank of this utility model adopts a split structure. The tank cover is installed at the discharge port. When installing the receiving tank, the tank body can be directly connected to the tank cover, which is convenient to operate. The pressure relief valve is installed on the tank cover, which can effectively prevent the material in the tank from causing adverse effects when the pressure is released.

[0016] The connecting assembly of this utility model uses a rocker arm, a push rod, and an L-shaped connector to work together. Simply by rocking the rocker arm, the tank body and the tank cover can be installed and disassembled, which is convenient to operate and has low maintenance costs.

[0017] The container of this utility model has a breathable packaging bag inside, which makes it easy to take the material out of the container without adversely affecting the vacuuming effect inside the container.

[0018] The pressure equalization pipe of this invention is a deformable flexible hose, which facilitates the disassembly and relocation of the receiving tank without the need for repeated disassembly and reassembly of the pressure equalization pipe.

[0019] This invention facilitates maintenance by setting an inspection port between the outlet of the vacuum storage tank and the receiving tank. Attached Figure Description

[0022] Figure 2 This is an enlarged view of the structure at point A of this utility model. Detailed Implementation

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Example This embodiment provides a feeding mechanism for a vacuum storage tank, such as... Figure 1 As shown, the feeding mechanism includes a receiving tank 3 and a pressure equalization pipe 4.

[0025] The vacuum storage tank 1 has a discharge port at its bottom. The receiving tank 3 is vertically positioned below the vacuum storage tank 1 and is detachably and sealed to the discharge port. A valve is installed at the discharge port to control whether the receiving tank is connected to the vacuum storage tank 1. One end of the pressure equalization pipe 4 is connected to the vacuum storage tank 1, and the other end is connected to the receiving tank 3. A pressure equalization valve 5 is installed on the pressure equalization pipe 4 to control its opening and closing. A pressure relief valve 6 is installed on the receiving tank 3 to control whether the inside of the receiving tank 3 is connected to the outside.

[0026] In this embodiment, the receiving tank 3 includes a tank body 32 and a tank cover 31. The tank cover 31 is installed at the discharge port, and the tank body 32 is located below the tank cover 31 and is detachably and sealed to the tank cover 31 through the connecting component 7. The pressure relief valve 6 is installed on the tank cover 31, and the pressure equalization pipe 4 is connected to the bottom of the tank body 32.

[0027] Among them, such as Figure 2 As shown, the connecting assembly 7 includes a rocker arm 71 and two push rods 74. The bottom of the tank cover 31 has a first flange plate 311, and the top of the tank body 32 has a second flange plate 321. The two push rods 74 are each mounted on opposite sides of the first flange plate 311 via an L-shaped connector 73. The L-shaped connector 73 is welded to the edge of the first flange plate 311. The push rods 74 are positioned below the first flange plate 311 and are rotatably mounted on the L-shaped connector 73 via a rotating shaft 75. The central axis of the rotating shaft 75 is horizontally oriented. A bushing 76 matching the rotating shaft 75 is mounted on the L-shaped connector 73, and the rotating shaft 75 is rotatably mounted within the bushing 76. One end of each push rod 74 is connected to the end of the rotating shaft 75 near the tank body 32, and the central axis of the push rod 74 is perpendicular to the central axis of the rotating shaft 75. Both ends of the rocker arm 71 are connected to the two push rods 74 via a connecting bracket 72. The two ends of the connecting frame 72 are respectively connected to the end of the rocker arm 71 and the end of the rotating shaft 75 away from the top rod 74. The rocker arm 71 drives the two top rods 74 to rotate between the first position and the second position through the connecting frame 72 and the rotating shaft 75.

[0028] When the push rod 74 is in the first position, the end of the push rod 74 away from the rotating shaft 75 is away from the first flange plate 311, leaving a distance between the push rod 74 and the first flange plate 311 for the second flange plate 321 to enter. When the tank body 32 is moved so that the second flange plate 321 enters between the first flange plate 311 and the push rod 74, and the push rod 74 rotates to the second position, the central axis of the push rod 74 is perpendicular to the second flange plate 321, and the push rod 74 applies an upward pushing force to the second flange plate 321, making the second flange plate 321 fit tightly against the first flange plate 311. To improve the sealing between the tank cover 31 and the tank body 32, a sealing ring is provided between the first flange plate 311 and the second flange plate 321, and the sealing ring is installed on the bottom surface of the first flange plate 311.

[0029] In this embodiment, a breathable packaging bag is built into the tank 32, with the bag opening located below the discharge port. This facilitates the removal of materials from the tank 32 without negatively impacting the vacuuming effect inside the material tank 3. The bottom of the tank 32 is equipped with casters 33 for easy movement. The equalizing pipe 4 is a deformable flexible hose, eliminating the need to remove it during tank movement.

[0030] In this embodiment, to facilitate the maintenance of the discharge port, the receiving tank 3 is connected to and communicates with the discharge port through the maintenance section 2. The maintenance section 2 is installed at the bottom of the discharge port, and the receiving tank 3 is installed at the bottom of the maintenance section 2. The maintenance section 2 has a maintenance port 21.

[0031] Working principle: When discharging material into the vacuum storage tank, place the packaging bag into the tank body 32, install the tank body 32, and connect it to the tank cover 31. Then, open the pressure equalization valve 5. The air in the receiving tank 3 enters the vacuum storage tank 1 through the pressure equalization pipe 4 and is discharged outside the vacuum storage tank 1 as the vacuum storage tank 1 is evacuated. The pressure inside the receiving tank 3 changes from normal pressure to a vacuum state consistent with that inside the vacuum storage tank 1. Close the pressure equalization valve 5, and then open the valve at the discharge port. The material is discharged under gravity. After the material is discharged, close the valve at the discharge port and open the pressure relief valve 6 to change the receiving tank 3 from a vacuum state to a normal pressure state. Then, open the receiving tank 3, pull the tank body 32 away from the tank cover 31, and remove the packaging bag containing the material.

[0032] Throughout the entire feeding process of the vacuum storage tank's feeding mechanism, the vacuum storage tank remains in a vacuum state, effectively preventing the material inside from becoming damp.
