Description

Percussion type Eucommia samara shell drying device

technical field

The utility model relates to a striking drying device for Eucommia ulmoides samara shells. the

Background technique

Eucommia ulmoides gum is a new and multi-purpose functional material with important application value. Eucommia ulmoides gum mainly exists in Eucommia ulmoides leaves, bark and fruit, and the gum content in Eucommia samara shell can reach more than 20%. It is an ideal raw material for extracting Eucommia gum.

Before the Eucommia samara shell is used to extract Eucommia gum, pretreatment is generally required to enhance the penetration of solvents, improve the yield and extraction efficiency of Eucommia gum, and the pretreatment methods mainly include alkali method, enzymatic method, etc. The common point is that water is used, but in actual operation, it is found that when the raw material of Eucommia ulmoides gum is leached with petroleum ether, it is easy to produce a mucus-like paste, which leads to a decrease in the solubility of the solvent to the glue and a decrease in the solvent penetration ability. Decrease, that is, a small amount of water in the samara shell has a great influence on the dissolution and leaching of the glue, so the material needs to be dried before leaching to improve the leaching effect.

Since the water in the pre-treated eucommia samara plant tissue exists not only in the cells, but also in the gaps between the glue filaments, and the dense glue filaments make it difficult to evaporate the water, so it is difficult for ordinary drying equipment to dry the water in a short time. The moisture in the raw material dries out, which has the defects of labor-intensive, time-consuming, high energy consumption and poor drying effect.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, aiming at the characteristics of the eucommia samara shell material, to provide a striking type eucommia samara shell drying device with simple structure, energy saving, fast drying speed and good effect.

Because a small amount of water in the shell of Eucommia ulmoides samara also seriously affects the leaching, the shell must be dried thoroughly, but the water inside the glue is difficult to remove, so it can be dried by vibration conveying in a sieve trough, and hammer crushing Machine, when the material passes through, it is hit at a high speed, and the hit material is blown loose like ginger, garlic, and cucumber when cooking, which is more conducive to the full evaporation and drying of water; in addition, by recovering the heat in the exhaust gas, it can Save energy and improve work efficiency.

Therefore, the technical scheme of the utility model is as follows:

A percussion type Eucommia ulmoides samara shell drying device, comprising a closed drying box, is characterized in that: the drying box is provided with a multi-layer sieve plate vibrating trough, and the sieve plate vibrating trough is connected with a vibration source and an elastic steel sheet, When the vibrating trough of the sieve plate vibrates, the elastic steel sheet can adjust the material conveying speed and direction; the vibrating trough of the uppermost sieve plate is connected to the lifting feeder; there are multiple hammer mills in the drying box, and the hammer mill The feed port of the machine is connected to the end point of the upper material direction, and the discharge port is connected to the starting point of the lower material direction; the upper part of the drying box is conical, the cone top is connected to the exhaust pipe, and the exhaust pipe is connected to the exhaust gas exhaust pipe through the exhaust gas heat exchanger; The inlet of the heater is connected to the blower, and the outlet is connected to the air distribution pipe through the steam coil fin heat exchanger, and the air distribution pipe is located in the drying box.

An insulation layer is provided outside the drying box to prevent heat loss.

The steam coil fin heat exchanger is provided with steam pipes and steam traps.

The steam coil fin heat exchanger is provided with a pressure gauge, which is convenient for monitoring the pressure of the steam coil fin heat exchanger.

The utility model recovers the waste heat from the tail gas discharged from the drying box through the tail gas heat exchanger, and improves the thermal efficiency by exchanging heat between the intake air and the exhaust gas. The heater further increases the air temperature. After the hot air enters the box, the hot air is evenly dispersed through the air distribution pipe.

The material enters the uppermost sieve plate vibrating trough in the drying box through the lifting feeder. The vibrating trough is made of sieve plate, which can make the air flow smooth and promote the drying of the material.

The structure of the sieve plate vibrating trough is simple and reliable. The material has the function of automatic diffusion and uniform distribution, and also has similar stirring and fluidization functions, which is especially conducive to the full contact between hot air and materials, enhancing heat and mass transfer and water evaporation. Multi-layer vibrating conveying is used for drying. If the top layer of material moves from left to right, the second layer of material moves from right to left, and so on. The bottom layer of material is output through the discharge port. The conveying direction and speed can be determined by the inclination direction of the elastic steel sheet. . Controlling a reasonable vibration mode can significantly improve work efficiency and prolong the service life of equipment.

When the material passes through the hammer mill, it is fully hit, rubbed, squeezed, and twisted to promote the loosening of the samara shell and facilitate the smooth evaporation of water from the glue of the samara.

Compared with the prior art, the utility model has the advantages of:

It solves the technical problem that the moisture in Eucommia rubber filaments is difficult to dry completely. By exchanging the waste heat in the exhaust gas with the fresh air, the exhaust heat emission is reduced, the work efficiency is improved, and energy is saved; a reasonable sieve plate vibrating trough is set Vibration mode or intermittent vibration can prolong the service life of the equipment without affecting the drying process; when the material passes through the hammer mill, the shell is blown loose, which actively promotes the water evaporation and drying process. The utility model has the advantages of simple structure, low cost, strong operability and strong industrialization value, and is suitable for drying Eucommia ulmoides husks in large quantities and in large quantities.
