Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid extraction, in particular to a solid-liquid extraction tower. Background Art

[0002] Solid-liquid extraction is a unit operation that uses organic or inorganic solvents to dissolve the soluble components in the solid raw materials, allowing them to enter the liquid phase, and then separate the insoluble solids from the solution. Its essence is the mass transfer process of solutes from the solid phase to the liquid phase. At present, solid-liquid extraction has a wide range of applications in pharmaceutical production, such as the extraction of effective ingredients in Chinese herbal medicines and the washing of solids. The solid-liquid extraction tower is one of the commonly used equipment for solid-liquid extraction. It is mainly suitable for the extraction between solid particles and solvents. Scientific tower structure design can more reasonably control the extraction time, solid-liquid contact mode, etc., and effectively improve the extraction effect.

[0003] In the solid-liquid extraction process, the solid-liquid contact area and contact time are the most important factors affecting the extraction efficiency, and these two aspects are determined by the structure of the extraction tower. At present, the existing solid-liquid extraction towers mainly include turntable type, fixed sieve plate type, packing type, and vibrating sieve plate type. However, these structures all have the following disadvantages: the solid raw material falls freely from top to bottom in the solution, and its residence time cannot be adjusted and controlled, that is, the solid-liquid contact time cannot reach the optimal value; the solid raw material is not evenly distributed in the extraction solvent, which affects the solid-liquid contact area. Utility Model Content

[0004] In view of the defects in the prior art, the purpose of the utility model is to provide a solid-liquid extraction tower. When the movable disk is close to the fixed disk, the solid is intercepted on the fixed disk and fully contacts with the solvent, and the contact time can be controlled by the time of the up and down reciprocating motion of the transmission shaft; when the movable disk is away from the fixed disk, the solid can fall in an arc through the fixed disk and the movable disk, and due to the stirring effect of the liquid material flowing, the solid raw material can be evenly distributed in the solvent, which can significantly improve the extraction efficiency.

[0005] The utility model provides a solid-liquid extraction tower, characterized in that it comprises:

[0006] A transmission shaft, the transmission shaft is connected to a driving device, and the driving device can drive the transmission shaft to move along its own axis;

[0007] a first ring and a second ring, wherein the first ring and the second ring are both mounted on the transmission shaft;

[0008] A fixed plate, the fixed plate is fixedly mounted on the side wall of the solid-liquid extraction tower, the center of the fixed plate passes through the transmission shaft, and at least one fan-shaped through hole is provided on the fixed plate;

[0009] A support ring, the support ring is located between the first sleeve ring and the second sleeve ring, and the support ring is slidably arranged on the transmission shaft;

[0010] A movable plate, wherein the size, shape and number of the movable plate correspond to the fan-shaped through holes one by one, one side of the movable plate is rotatably connected to the side of the fixed plate away from the transmission shaft, and the other side of the movable plate close to the transmission shaft is directly overlapped on the support ring, and a circular through hole is opened on the movable plate, and the circular through hole corresponds to the position of the fan-shaped through hole;

[0011] A screen is fixedly mounted on the circular through hole of the movable disk.

[0012] In one embodiment, a spring is further included, wherein the spring is sleeved on the transmission shaft and the spring is located between the support ring and the second sleeve ring.

[0013] In one embodiment, the diameter of the screen is greater than the diameter of the circular through hole.

[0014] In one embodiment, the circumference of the fixed disk is fixedly connected to the side wall of the solid-liquid extraction tower via a sealing rubber.

[0015] In one embodiment, the driving device is one of a motor, a cylinder, and a hydraulic cylinder capable of reciprocating drive.

[0016] In one embodiment, one side of the movable disk is rotatably connected to a side of the fixed disk away from the transmission shaft via a hinge.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. In the solid-liquid extraction tower provided by the utility model, the transmission shaft drives the supporting ring to move up and down reciprocatingly, and then drives the movable disk to move away from or close to the fixed disk with the hinge as the axis. When the movable disk is close to the fixed disk, the solid is intercepted on the fixed disk and fully contacts with the solvent. The contact time can be controlled by the time of the up and down reciprocating motion of the transmission shaft; when the movable disk is away from the fixed disk, the solid can fall in an arc through the fixed disk and the movable disk. In addition, due to the stirring effect of the liquid material during the flow, the solid raw material can be evenly distributed in the solvent, which can significantly improve the extraction efficiency.

[0019] 2. In the solid-liquid extraction tower provided by the utility model, the driving device can be selected from motors, cylinders, hydraulic cylinders and other devices, which can drive the transmission shaft to reciprocate up and down, and can also adjust the reciprocating frequency of the driving device through very common automation means, thereby controlling the residence time of the solid material on the fixed disk.

[0020] 3. In the solid-liquid extraction tower provided by the utility model, the processing accuracy and installation accuracy of each component are required to be relatively low, which saves the installation cost of the entire solid-liquid extraction tower and is easy for daily maintenance.

[0034] The support ring 7 is slidably mounted on the transmission shaft 1, and the support ring 7 reciprocates between the first sleeve ring 21 and the second sleeve ring 22;

[0035] The size, shape and number of the movable disk 6 correspond one to one with the fan-shaped through holes on the fixed disk 5, that is, the movable disk 6 is a fan-shaped disk, and the number of the movable disk 6 is consistent with the fan-shaped through holes on the fixed disk 5, which is six. One side of the movable disk 6 is rotatably connected to the side of the fixed disk 5 away from the transmission shaft 1 through a hinge 9, and the other side of the movable disk 6 close to the transmission shaft 1 is directly overlapped on the supporting ring 7.
