Description

Technical Field

[0001] This utility model relates to the field of degassing tank technology, and in particular to a degassing tank discharge structure. Background Technology

[0002] The working principle of a vacuum degassing tank is to place the liquid in a vacuum environment, causing the free and dissolved gases in the liquid to be released. A vacuum pump is used inside the degassing tank to create a negative pressure environment, removing gases from the container. Degassing tanks are commonly used for vacuum degassing of products such as fruit juice and liquid milk to prevent oxidation, browning, and improve appearance.

[0003] like Figure 1 This is a commonly used vacuum degassing tank structure on the market. The tank body a has a conical bottom b with the tip of the conical bottom b facing downwards, and a discharge pipe c is set in the center of the conical bottom b. This structure has certain defects: for example, when discharging, the liquid is easily vortexed when it is guided by the conical bottom b and discharged from the central discharge pipe c, which makes the pump prone to cavitation and affects the pump's working efficiency; in addition, this structural design makes the liquid flow path in the tank body a short, which affects the degassing effect of the liquid.

[0004] Based on this, the present invention proposes a degassing tank discharge structure to solve the problems mentioned above. Utility Model Content

[0027] The degassing tank discharge structure of this utility model will be described in more detail below with reference to the schematic diagram, which illustrates the preferred embodiment of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0028] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0029] like Figure 2 As shown in the figure, this utility model embodiment proposes a degassing tank discharge structure, including a base plate 1, a discharge cylinder 2, and a cleaning mechanism 3.

[0030] Specifically, the base plate 1 is set at the bottom of the degassing tank 01 and is used to seal the bottom of the degassing tank 01; the top surface of the base plate 1 is a cone structure 10 with the tip pointing upwards, and the central axis of the cone structure 10 coincides with the central axis of the degassing tank 01; one end of the discharge cylinder 2 is connected to the bottom edge of the base plate 1 and communicates with the inside of the degassing tank 01; the cleaning mechanism 3 is installed on the base plate 1 and is used to sweep the medium remaining at the junction of the base plate 1 and the degassing tank 01 to the discharge cylinder 2.

[0031] In this embodiment, the top surface of the base plate adopts a cone-shaped design with the tip pointing upwards. This, combined with the connection of one end of the discharge cylinder to the edge of the base plate, allows the degassing tank to achieve lateral discharge from a reverse cone bottom. The inclined surface of the reverse cone bottom guides the material to slide unidirectionally along the inclined bottom towards the side wall discharge port, rather than converging towards the center. This flow pattern is closer to "laminar slip," with a consistent fluid direction, reducing the lateral velocity component and thus reducing the rotational tendency, effectively minimizing vortex generation. Vortexes can draw air into the pump, forming a gas-liquid mixture. This reduces pump efficiency because air is less dense than liquid, resulting in poor work done by the impeller on air, leading to a decrease in head and flow rate. Furthermore, if the vortex causes a decrease in suction pressure, when the pressure falls below the liquid's saturated vapor pressure, the liquid will vaporize to form bubbles. These bubbles enter the high-pressure zone of the impeller and burst, generating impact force that damages the impeller, while also producing noise and vibration. This is cavitation, which not only affects efficiency but also shortens the pump's lifespan. Therefore, the degassing tank discharge structure provided in this embodiment reduces vortex generation, thus improving pump efficiency.

[0032] Furthermore, in this embodiment, the use of a reverse cone bottom for lateral discharge can increase the movement path of the liquid in the degassing tank, allowing the liquid to remain in the degassing tank for a longer time, thereby improving the degassing effect of the liquid.

[0033] Furthermore, in this embodiment, due to the use of a lateral discharge form with an inverted conical bottom, a small amount of material is easily retained at the junction of the bottom plate 1 and the degassing tank 01 after discharge. If this retained material is not removed, it will affect the subsequent use of the degassing tank 01. In this embodiment, the cleaning mechanism 3 sweeps the medium retained at the junction of the bottom plate 1 and the degassing tank 01 to the discharge cylinder 2, achieving effective cleaning of the dead corners inside the degassing tank 01.

[0034] In the above embodiment, the cleaning mechanism 3 includes a cleaning block 30, a rotating shaft 31, and a connecting rod 32; the cleaning block 30 is placed at the junction of the base plate 1 and the degassing tank 01; the rotating shaft 31 is rotatably installed at the center of the base plate 1; the two ends of the connecting rod 32 are respectively connected to the cleaning block 30 and the rotating shaft 31.

[0035] Specifically, refer to Figure 3 The base plate 1 has a through-hole (not shown in the figure) in the middle, and the rotating shaft 31 passes through the mounting hole and is rotatably connected to the base plate 1. By driving the rotating shaft 31 to rotate from outside the degassing tank 01, the cleaning block 30 can be driven by the connecting rod 32 to perform circumferential cleaning of the junction between the base plate 1 and the degassing tank 01.

[0036] To ensure the smooth rotation of the rotating shaft 31, the rotating shaft 31 is rotatably connected to the base plate 1 through the rotating bearing 33.

[0037] Preferably, a power motor 34 is connected to the bottom end of the rotating shaft 31, and the power motor 34 is mounted on the bottom surface of the base plate 1. The power motor 34 enables automated cleaning of the cleaning block 30.

[0038] Necessarily, a sealing element is installed on the rotating shaft 31 to seal the mounting hole, ensuring the sealing of the bottom of the degassing tank.

[0039] Specifically, the sealing element includes a plurality of O-rings 35, which are installed at intervals on the rotating shaft 31, and the O-rings 35 are in close contact with the sidewall of the mounting hole.

[0040] To ensure stable installation of the multiple O-rings 35, multiple annular dovetail grooves 310 are spaced apart on the rotating shaft 31. The multiple O-rings 35 are correspondingly fitted into the multiple annular dovetail grooves 310, such as... Figure 4 As shown.

[0041] When installing the O-ring 35, it is embedded in the annular dovetail groove 310. The axial fixation is achieved by utilizing the inclined self-locking effect of the annular dovetail groove 310. Compared with the traditional rectangular groove, the O-ring cannot slide freely along the axial direction in the groove, making the installation of the O-ring 35 more stable.

[0042] In the above embodiment, multiple reinforcing rods 4 are connected between the discharge cylinder 2 and the bottom surface of the base plate 1 to improve the stability of the discharge cylinder 2 installation.

[0043] In summary, compared with the prior art, this utility model has at least the following advantages:

[0044] The degassing tank discharge structure provided by this utility model includes a bottom plate with a cone-shaped top surface that points upwards. One end of the discharge cylinder is connected to the edge of the bottom surface of the bottom plate, which enables the degassing tank to achieve lateral discharge with an inverted cone bottom. This effectively reduces the generation of vortices and improves the flow path of the liquid inside the degassing tank, thereby improving the working efficiency of the pump and the degassing effect of the liquid.

[0045] Furthermore, the degassing tank discharge structure provided by this utility model has a cleaning mechanism installed on the bottom plate. The cleaning mechanism sweeps the medium that remains at the junction of the bottom plate and the degassing tank to the discharge cylinder, thus achieving effective cleaning of the dead corners inside the degassing tank.

[0046] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
