Description

Technical Field

[0001] This utility model relates to the technical field of equipment for extracting effective components from natural plants, and in particular to a supernatant discharge device and a sedimentation tank for natural plant enzymatic hydrolysis extract. Background Technology

[0002] In the extraction of effective components from natural plants, enzymatic hydrolysis is often used. The extract after enzymatic hydrolysis needs to be allowed to stand in a settling tank to separate into layers. The upper layer is a clear supernatant containing the effective components to be extracted, while the lower layer is a precipitate and residue.

[0003] Currently, the discharge device of settling tanks is usually a single discharge port fixed at the bottom or lower side of the tank. When discharging the supernatant, as the liquid level drops, the sediment in the lower layer is easily carried out with it, affecting the purity of the supernatant. If only a discharge port at a higher position is set, the supernatant may not be completely discharged, resulting in waste.

[0004] Therefore, a discharge device is needed that can flexibly adjust the discharge position according to the supernatant level, so as to ensure the purity of the supernatant and fully discharge the supernatant. Utility Model Content

[0005] The purpose of this invention is to provide a supernatant discharge device and a sedimentation tank for natural plant enzymatic hydrolysis extracts, which can flexibly adjust the discharge position according to the supernatant level, and has a simple structure and is easy to operate.

[0006] The objective of this utility model can be achieved by the following technical solutions:

[0007] This utility model provides a supernatant discharge device for installation inside a tank. The supernatant discharge device includes a vertically arranged and closed-end vertical pipe. Multiple horizontal pipes are connected from top to bottom along the vertical pipe. A liquid inlet is provided on each horizontal pipe. A piston capable of sealing and sliding is provided inside each horizontal pipe. The piston can block or open the liquid inlet by moving. A discharge pipe is connected to the bottom side wall of the vertical pipe, and a main discharge valve is provided on the discharge pipe. The vertical pipe is used for installation inside the tank. Both the horizontal pipes and the discharge pipe can be sealed through the side wall of the tank. The liquid inlet is located inside the tank, and the main discharge valve is located outside the tank.

[0009] In a preferred embodiment of this utility model, a handle is provided at the end of the piston rod extending out of the horizontal tube.

[0010] In a preferred embodiment of this utility model, the liquid inlet is a circular hole with a diameter of 8-15mm, and the distance between two adjacent horizontal pipes is 30-50mm.

[0011] This utility model also provides a sedimentation tank for natural plant enzymatic hydrolysis extract, including a vertically arranged tank body and the above-mentioned supernatant discharge device; the top and bottom of the tank body are respectively provided with an openable and closable feed port and a drain port, and the tank body is provided with an observation window.

[0032] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0033] like Figures 1 to 3 As shown, this application provides a supernatant discharge device for installation inside a tank 1. The supernatant discharge device includes a vertically arranged and closed-end vertical pipe 2. Multiple horizontal pipes 3 are connected from top to bottom on the vertical pipe 2. An inlet 31 is provided on the horizontal pipe 3. A piston 32 that can be sealed and slid inside the horizontal pipe 3 is provided. The piston 32 can block or open the inlet 31 by moving. A discharge pipe 4 is connected to the bottom side wall of the vertical pipe 2. A main discharge valve 41 is provided on the discharge pipe 4. The vertical pipe 2 is used to install inside the tank 1. Both the horizontal pipes 3 and the discharge pipe 4 can be sealed through the side wall of the tank 1. The inlet 31 is located inside the tank 1, and the main discharge valve 41 is located outside the tank 1.

[0034] Therefore, the supernatant discharge device of this application, by arranging multiple horizontal pipes 3 with inlets 31 vertically, and each horizontal pipe 3 containing a piston 32 capable of blocking or opening the inlet 31, ensures that all inlets 31 and the main discharge valve 41 are closed when the supernatant discharge device is in its initial state. When the supernatant discharge device is in the discharge state, as the supernatant level decreases, each inlet 31 can be gradually opened from top to bottom according to the supernatant level, ensuring that only the supernatant is discharged, avoiding the mixing of lower sediment, and effectively improving the purity of the supernatant. The entire device has a simple structure, is easy to operate, can fully discharge the supernatant, reduce the waste of effective components, and improve extraction efficiency.

[0035] Furthermore, this application also provides a sedimentation tank for natural plant enzymatic hydrolysis extract, including a vertically arranged tank body 1 and the aforementioned supernatant discharge device; an openable and closable inlet 11 and a drain outlet 13 are respectively provided at the top and bottom of the tank body 1, and an observation window is provided on the tank body 1.

[0036] The sedimentation tank includes the aforementioned supernatant discharge device and has the same advantages.

[0037] Specifically, tank 1 is a hollow tank closed at both ends. The inlet 11 at the top of tank 1 is used to add the liquid to be allowed to settle and separate, such as natural plant enzymatic extract. The drain 13 at the bottom of tank 1 is used to drain the sediment after settling and separation. The cross-sectional shape of tank 1 can be circular or square, depending on the specific requirements. The vertical pipe 2 can be connected via a suitable support (e.g., Figure 2 The fixing rod 16 is fixed inside the tank body 1. The drain pipe 4 is also placed horizontally and located below the bottommost horizontal pipe 3. The vertical pipe 2, each horizontal pipe 3, and the drain pipe 4 should be made of rigid pipe for easy installation. Multiple mounting holes are provided on the side wall of the tank body 1 for the horizontal pipes 3 and the drain pipe 4 to pass through. The specific number of horizontal pipes 3 depends on actual needs. The inlet 31 on each horizontal pipe 3 can be opened on the top of the side wall of the horizontal pipe 3. The inlet 31 is closed or opened by the movement of the piston 32.

[0038] Taking four horizontal pipes 3, labeled from top to bottom as first horizontal pipe 301, second horizontal pipe 302, third horizontal pipe 303, and fourth horizontal pipe 304, and their respective inlets 31 labeled from top to bottom as first inlet 311, second inlet 312, third inlet 313, and fourth inlet 314, in the initial state, the pistons 32 in each horizontal pipe 3 block their respective inlets 31, and all inlets 31 are closed. The aforementioned main drain valve 41 is also closed. In use, the natural plant enzymatic extract is added to the tank 1 through the feed inlet 11 and allowed to stand and separate. When the required standing time has been reached, the piston 32 in the first horizontal pipe 301 is moved to open the first inlet 311. The supernatant after separation in the tank 1 flows in from the first inlet 311. The main drain valve 41 is then opened to release the uppermost supernatant. The operator observes the liquid level of the supernatant through the observation window on tank 1. After the uppermost layer of supernatant is drained, the piston 32 in the second horizontal pipe 302 is opened to open the second inlet 312 for liquid inflow. This process is repeated as the supernatant level decreases. The second inlet 312 and the third inlet 313 can be opened sequentially downwards until some unclarified liquid is discharged. At this point, the main drain valve 41 is closed, and the supernatant is completely drained.

[0039] Furthermore, a movable piston rod 33 is also inserted inside the horizontal tube 3, and the piston 32 is sleeved and fixed on the piston rod 33, with one end of the piston rod 33 extending out of the horizontal tube 3.

[0040] The first end of the horizontal pipe 3 is located inside the tank body 1 and connected to the vertical pipe 2. The second end of the horizontal pipe 3 extends outside the tank body 1. The diameter of the piston rod 33 should be smaller than the inner diameter of the horizontal pipe 3. The piston 32 is a cylindrical structure fitted onto the first end of the piston rod 33 and has a sealing sliding fit with the horizontal pipe 3. The second end of the piston rod 33 extends out of the horizontal pipe 3 for easy operation by the operator. By pushing the piston rod 33 inward or pulling it outward, the operator can make the piston 32 block or open the liquid inlet 31. Optionally, a handle 34 is provided at the end of the piston rod 33 extending out of the horizontal pipe 3 to make it easier for the operator to move the piston rod 33.

[0041] The inner diameter of the vertical pipe 2, the inner diameter of the horizontal pipe 3, the shape and size of the inlet 31, the inner diameter of the outlet pipe 4, and the spacing between two adjacent horizontal pipes 3 are designed according to actual needs. For example, the inlet 31 can be a circular hole with a diameter of 8-15mm, and the spacing between two adjacent horizontal pipes 3 can be 30-50mm. This size setting can ensure a suitable discharge speed while avoiding the impact of excessive spacing between two adjacent horizontal pipes 3 on the adjustment accuracy of the discharge position. For example, in a specific case, the inlet 31 is a circular hole with a diameter of 10mm, and the spacing between two adjacent horizontal pipes 3 is 40mm.

[0042] Alternatively, the observation window is a transparent glass piece located on the side wall of the tank 1, with vertically graduated lines on it. This observation window can be a long strip of transparent glass, vertically aligned, to allow operators to observe the liquid level stratification and changes in the supernatant level. The graduated lines help operators accurately determine the supernatant level, thereby controlling the opening of the corresponding inlet 31 to precisely control the discharge height and improve operational accuracy.

[0043] Alternatively, to facilitate the collection of supernatant, the end of the drain pipe 4 extending out of the tank body 1 is connected to a collection tank.

[0044] Alternatively, a pump can be installed on the discharge pipe 4 to improve discharge efficiency. The pump is also located outside the tank 1. Of course, if needed, the pump can be omitted from the discharge pipe 4, allowing the supernatant to flow automatically into the collection tank.

[0045] Optionally, a feed pipe 12 is connected to the feed inlet 11, a conveying pump is installed on the feed pipe 12, and a feed valve 121 is installed on the feed pipe 12 near the feed inlet 11 to facilitate feeding. A drain pipe 14 is connected to the drain outlet 13, and a drain valve 141 is installed on the drain pipe 14 to facilitate drainage and cleaning of sediment at the bottom of the tank.

[0046] For the valves mentioned above, ball valves or gate valves can be used, which are easy to operate and have good sealing performance.

[0047] Alternatively, the bottom surface of tank 1 may be an outwardly convex arc-shaped bottom surface to facilitate the discharge of sediment from the bottom.

[0048] Alternatively, a support leg 15 may be provided at the bottom of the tank body 1 to support the tank body 1.

[0049] In summary, the supernatant discharge device and the sedimentation tank for natural plant enzymatic hydrolysis extract in this embodiment can flexibly adjust the discharge position according to the supernatant level, ensuring the purity of the supernatant, while fully discharging the supernatant to reduce waste. The structure is simple and the operation is convenient.

[0050] It is understood that the supernatant discharge device and sedimentation tank of this application are not limited to the extraction of natural plant enzymatic hydrolysis extracts, but can also be used for other liquids that require static layering extraction.

[0051] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
