Description

Soft clapboard penetrating countercurrent dryer

technical field

The utility model relates to a dryer, in particular to a soft partition type penetrating countercurrent dryer.

Background technique

People generally refer to drying with a drying temperature below 60 degrees Celsius as low-temperature drying. Low-temperature drying is widely used in the drying of heat-sensitive materials such as crop seeds, Chinese medicinal materials, and biological products. Due to its mature technology, strong adaptability, low operating cost and high reliability, hot air dryer is still one of the first choice equipment for low temperature drying. Low-temperature drying is less easy to recover tail heat due to the lower exhaust temperature. If the penetration and countercurrent drying of materials can be realized in the hot-air low-temperature drying process, and the tail heat can be effectively recovered, it will be of great significance for improving drying efficiency and realizing energy saving and emission reduction.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a soft partition type penetrating countercurrent dryer with a simple and practical structure.

In order to overcome the deficiencies in the prior art, the utility model adopts the following technical solutions:

A soft clapboard type penetrating countercurrent dryer, comprising a dryer box and an induced draft fan, characterized in that: the two ends of the dryer box are respectively provided with an exhaust hood and an air inlet hood, the exhaust hood is connected to the induced draft fan, and the induced draft fan The evaporator of the heat pump system is connected to the cyclone dust collector and then emptied; the evaporator of the heat pump system is connected to the host through the refrigerant pipe, and the host is connected to the condenser through the refrigerant pipe; the outlet end of the blower is connected to the air inlet hood through the condenser; the dryer box There are driving rollers and driven rollers in the body to drive the sieve plate steel belt to pass through. The sieve plate steel belt divides the dryer cabinet into an upper cabinet and a lower cabinet. There are multiple vertically arranged soft partitions in the upper and lower cabinets. The board separates the upper and lower cabinets into several units. The soft partition lightly presses the material to completely block the air flow but does not affect the material conveying. The unit is equipped with an axial flow fan with the upper fan facing down and the lower fan going up. After the axial flow fan is turned on, the airflow can be forced to pass through the steel belt of the sieve plate and the material above it to realize penetrating countercurrent drying.

The two ends of the sieve plate steel belt are respectively provided with a feed hopper and a discharge hopper to realize continuous feed drying.

When the equipment is working, the material is fed evenly by the feeding hopper, and the steel belt of the sieve plate passes through the inside of the dryer. After the axial flow fan is turned on, due to the isolation effect of the soft partition, the airflow can only be forced to pass through the steel belt of the sieve plate and the The material above it is subjected to penetrating countercurrent drying; the exhaust hood is connected to the inlet of the induced draft fan, and the hot and humid tail gas is cyclone-dusted and then introduced into the fin evaporator to complete tail heat recovery. The heat is released in the condenser, and the air blown in by the blower exchanges heat on the finned condenser and then enters the dryer through the air inlet hood to complete the penetrating countercurrent drying and tail heat recovery.

Compared with the prior art, the utility model has the beneficial effects of:

Through the induced draft fan, soft partition and axial fan, the penetrating countercurrent drying of the material is cleverly realized, which improves the drying efficiency and speed, and reduces energy consumption; the heat pump tail heat recovery is suitable for the heat with low tail gas temperature Recycling is particularly efficient and convenient.
