Multifunctional continuous extraction solid-liquid separation combined machine

Abstract

Provided is a multifunctional continuous extraction solid-liquid separation combined machine. The multifunctional continuous extraction solid-liquid separation combined machine comprises a roller body, a feeding hopper and a discharging port, wherein the roller body is horizontally arranged on a machine frame or arranged on the machine frame in an inclined mode, the feeding hopper is located at the feeding end of the roller body, and the discharging port is located at the discharging end of the roller body. A spiral blade and a water collecting box are arranged on the inner wall of the roller body, a water filter device is arranged at the discharging end of the roller body and located in front of the discharging port, the front portion and the rear portion of the roller body are sleeved with a large gear ring and a large rolling ring respectively, the large rolling ring is arranged on a supporting wheel arranged on the machine frame, and a pinion meshed with the large gear ring is arranged on an output shaft of a variable frequency motor arranged on the machine frame. According to the multifunctional continuous extraction solid-liquid separation combined machine, a material and water can be evenly mixed, the separation phenomenon is avoided, the water adding amount of the material can be reduced, the solid-to-liquid ratio is reduced, the mixture is evenly mixed, the concentration of extracted liquid is improved, the extraction rate is increased, the material filling rate is high, and the material is cleanly discharged. The multifunctional continuous extraction solid-liquid separation combined machine is simple in structure and convenient to operate and maintain. Power consumption is small, and an energy saving effect is obvious.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaf production by papermaking method. Background technique [0002] At present, in the domestic production of reconstituted tobacco leaves by the papermaking method, raw materials such as tobacco stems, shredded tobacco leaves, and tobacco powder are extracted with a solvent by using an extraction tank, and then solid-liquid separation is performed on the output. Material extraction and solid-liquid separation need to be completed by two sets of equipment, occupying a large area, many equipment, many transmission points to be controlled, complex structure, high maintenance equipment costs, and high investment costs. The extraction tank is mainly used for extracting tobacco stems, shredded tobacco leaves and tobacco powder under stirring state with hot water as medium. The extraction tank heats water while feeding, soaks and stirs and then discharges the material. The material and w...

AI Technical Summary

Problems solved by technology

The disadvantages are: due to the light bulk density of the shredded tobacco leaves and tobacco powder, the shredded tobacco leaves float on the surface after adding water, and the stirring parts cannot achieve the effect of uniform mixing of materials and water

Due to the unreasonable structure, the transmission point is inside the conical tank, which is prone to oil leakage and high maintenance cost

And the tobacco stems are easy to bridge in the cone, and the discharge is not smooth. When the valve plate of the lower discharge port is opened, the water flows out first, and the material and water cannot be discharged uniformly at the same time, resulting in large fluctuations in the concentration of the discharge, resulting in unstable concentration in the press. , affecting the extraction rate

In addition, the valve plate at the discharge port of the extraction tank is frequently opened and closed, and the gasket is easily damaged, resulting in liquid leakage, which needs to be replaced frequently
