Description

Technical Field

[0001] This utility model relates to the field of liquid separation equipment technology, specifically a liquid-liquid separator that can control the discharge height of liquids. Background Technology

[0002] In many industrial sectors such as food, chemicals, and environmental protection, liquid-liquid separation is a common and crucial production process. Its principle typically utilizes the density difference between different liquids, causing them to separate into layers within a container under static or centrifugal conditions, and then discharged separately. Traditional liquid-liquid separators usually have fixed discharge ports for the light and heavy phases. This structure lacks the necessary flexibility to handle different materials and separation requirements. When the interface layer of the liquids to be separated does not match the height of the fixed discharge port, incomplete separation can easily occur, resulting in one phase of liquid mixed with another. This not only affects product purity and quality but may also increase the cost and difficulty of subsequent processing.

[0003] To address these issues, the industry has made some attempts, such as setting multiple fixed discharge ports at different heights. However, this method increases manufacturing costs and structural complexity, and the number of discharge ports limits the accuracy of liquid level selection, making continuous stepless adjustment impossible. Furthermore, too many openings also increase the risk of leakage at the equipment's connection points.

[0004] Therefore, there is an urgent need for a liquid-liquid separation device that can flexibly and accurately control the discharge level and ensure reliable sealing during operation.

[0005] A search revealed a low-cost, high-efficiency liquid-liquid separation device disclosed in Chinese patent literature [Application No.: 202223315886.8, Publication No.: CN219110894U], comprising a storage tank and an inlet pipe and a gas phase outlet pipe located at the top of the tank. While this comparative patent achieves basic liquid-liquid separation and features a simple structure, the present invention, through its core mechanism of a "rotatable bending discharge pipe," achieves stepless and continuous adjustment of the discharge liquid level within the height range of the material tank's sidewall. In contrast, the positions of the light phase outlet pipe and the heavy phase outlet pipe in the comparative patent are pre-set and cannot be changed. This means that once the equipment is manufactured, the height of the separated and discharged liquid layer is fixed, making it unable to flexibly adapt to different working conditions or changes in the material stratification interface. The rotary adjustment mechanism of the present invention provides operational flexibility, allowing precise extraction of liquid layers of any depth using only one device. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a liquid-liquid separator that can control the liquid at different discharge heights.

[0007] A liquid-liquid separator capable of controlling liquids at different discharge heights, characterized in that it comprises: a material tank, wherein the top of the material tank is provided with a feeding port, the bottom of the material tank is provided with a discharge port, and the side wall of the material tank is provided with a discharge port for the separated liquid; A bent discharge pipe is movably installed at the liquid discharge port of the separated liquid. The bent discharge pipe includes a branch pipe located inside the material tank and a connecting pipe located outside the material tank.

[0008] Preferably, the bottom of the material container has a conical structure.

[0009] The above technical solution enables the natural convergence and rapid sedimentation of liquids during the separation process, and makes the tank structure more compact. The conical bottom design not only guides the liquid to drain in a concentrated manner, but also effectively reduces the overall size of the equipment.

[0010] Specifically, the conical structure utilizes gravity to allow denser liquids to slide down the tank wall and concentrate at the bottom discharge port, thus making the stratification interface clearer and reducing the risk of liquid mixing. The conical contraction of the bottom space reduces dead corners and residual liquid accumulation. At the same time, the conical structure at the bottom reduces the volume, allowing the liquid to be located within the working range of the bent discharge pipe as much as possible, improving work efficiency.

[0011] Preferably, the connecting pipe is provided with a rotating gear, which is engaged with a rotating handwheel located outside the material barrel.

[0012] The above technical solution enables controllable adjustment of the discharge height. The linkage structure between the gear and the handwheel allows the bent discharge pipe to rotate stably, thus enabling discharge selection at different liquid levels.

[0013] Specifically, when the operator turns the handwheel, the rotating gear drives the connecting pipe to rotate, causing the branch pipe inside the tank to align with different liquid levels, thus enabling flexible switching of liquid level. The entire adjustment process is compact, reliable in transmission, and allows for smooth angle changes.

[0014] Preferably, the branch pipe has a teardrop-shaped reverse flow structure.

[0015] The above technical solution reduces disturbance to the separation interface during liquid discharge, maintaining the stability of stratification. The reverse flow structure design makes the liquid flow direction more stable.

[0016] Specifically, the branch pipe ends are arranged downwards, allowing the liquid to flow naturally down the inner wall, avoiding the carrying of upper liquid or air bubbles during suction; at the same time, this configuration creates a flow buffer zone inside the pipe, reducing sudden changes in liquid velocity and thus maintaining the clarity of the liquid surface boundary.

[0017] Preferably, a glass window is provided on the side wall of the material barrel, and the glass window is located in the height area corresponding to the connecting pipe.

[0018] The above technical solution enables real-time observation of the liquid stratification within the material tank. The glass viewing window facilitates accurate assessment of the separation status when adjusting the discharge height.

[0019] Specifically, the glass window is set at a height corresponding to the draining mechanism, allowing the operator to observe changes in the liquid level and liquid layers through the transparent window, and to intuitively grasp the separation process when adjusting the rotating handwheel or opening the drain valve.

[0020] Preferably, a heating rod is provided at the bottom of the material container.

[0021] The above technical solution enables the liquid to be heated during the separation process, improving its fluidity and sedimentation properties. The heating device can also promote the stratification between different liquids.

[0022] Specifically, the heating rod is positioned at the bottom of the tank. By uniformly heating the liquid, it enhances the fluidity of the high-viscosity liquid, thereby accelerating the separation of liquids with different densities. The heating temperature can be controlled within a suitable range to ensure the stability of the liquid layer and prevent its disruption.

[0023] Preferably, a sealing element is provided at the connection between the material tank and the separation liquid discharge port, and the bent discharge pipe is connected to the material tank through this sealing element.

[0024] The above technical solution prevents liquid leakage during rotation or discharge, keeping the system sealed and clean. This sealing structure provides a stable sealing effect during dynamic rotation.

[0025] Specifically, the sealing element is installed at the interface between the discharge port and the bent discharge pipe. Its elastic structure can be finely adjusted and compensated for the displacement generated by rotation, thereby continuously maintaining the sealing state and preventing liquid leakage or air ingress.

[0026] Compared with the prior art, the present invention has the following advantages: 1. This utility model achieves flexible discharge of liquids at different levels by incorporating a rotatable, bent discharge pipe. Users can adjust the position of the branch pipes to select the discharge layer based on the liquid stratification, thus making the separation process more targeted. This structure maintains airtightness while reducing the possibility of liquid mixing, making the separation operation smoother and more efficient.

[0027] 2. This utility model employs a conical bottom, a reverse-flow branch pipe, and a sealed rotary connection to create a more compact overall device and a smoother liquid flow path. The combined use of heating and observation devices makes it easier to monitor and control the liquid stratification state, thereby improving the operability and stability of the separation process.

[0038] Specifically, when the operator turns the rotary handwheel, the rotating gear drives the connecting pipe to rotate, causing the branch pipe 51 located inside the tank to correspond to different liquid layer positions, thus achieving flexible switching of liquid level height.

[0042] Specifically, the branch pipe ends are arranged downwards, allowing the liquid to flow naturally down the inner wall, avoiding the carrying of upper liquid or air bubbles during suction; at the same time, this configuration creates a flow buffer zone inside the pipe, reducing sudden changes in liquid velocity and thus maintaining the clarity of the liquid surface boundary.

[0043] In practical applications, this structure can effectively improve separation quality, ensure the stability of the stratification interface of liquids with different densities, and reduce the occurrence of mixing and backmixing.

[0044] Specifically, a glass window 7 is provided on the side wall of the material barrel 1, and the glass window 7 is located in the height area corresponding to the connecting pipe 52.

[0045] The above technical solution enables real-time observation of the liquid stratification within the material tank. The glass viewing window facilitates accurate assessment of the separation status when adjusting the discharge height.

[0046] Specifically, the glass window is set at a height corresponding to the draining mechanism, allowing the operator to observe changes in the liquid level and liquid layers through the transparent window, and to intuitively grasp the separation process when adjusting the rotating handwheel or opening the drain valve.

[0047] In practical applications, this structure makes the liquid-liquid separation process more visible, significantly improving operational safety and controllability, and reducing misoperations caused by limited visibility.

[0048] Specifically, a heating rod 8 is provided at the bottom of the material bin 1.

[0049] The above technical solution enables the liquid to be heated during the separation process, improving its fluidity and sedimentation properties. The heating device can also promote the stratification between different liquids.

[0050] Specifically, the heating rod is positioned at the bottom of the tank. By uniformly heating the liquid, it enhances the fluidity of the high-viscosity liquid, thereby accelerating the separation of liquids with different densities. The heating temperature can be controlled within a suitable range to ensure the stability of the liquid layer and prevent its disruption.

[0051] In practical applications, this structure can shorten the separation time, improve the stability of the stratification effect, maintain the uniformity of the discharge flow rate, and enhance the continuity and controllability of the separation process.

[0052] Specifically, a sealing element 9 is provided at the connection between the material tank 1 and the separation liquid discharge port 4, and the bent discharge pipe is connected to the material tank 1 through the sealing element 9.

[0053] The above technical solution prevents liquid leakage during rotation or discharge, keeping the system sealed and clean. This sealing structure provides a stable sealing effect during dynamic rotation.

[0054] Specifically, the sealing element is installed at the interface between the discharge port and the bent discharge pipe. Its elastic structure can be finely adjusted and compensated for the displacement generated by rotation, thereby continuously maintaining the sealing state and preventing liquid leakage or air ingress.
