Double-side air blowing type leather processing equipment

Abstract

The invention discloses double-side air blowing type leather processing equipment. A fan (1) is sequentially connected with an air heater (2) and drying equipment (3), a water supply box (12) provides hot water for the air heater (2), cold water of the air heater (2) is heated by a solar water heater (14) and a buried-pipe heat collector (17) and then returns to the water supply box (12), the drying equipment (3) is connected with a first moisture absorption device (4) and a second moisture absorption device (5) respectively through a three-way valve A (7), air outlets of the moisture absorption devices are connected with emptying pipes and air return pipes respectively, and a regeneration fan (6) is used for performing desorption on the moisture absorption devices which are saturated through adsorption. The leather processing equipment has the benefits as follows: solar energy is fully utilized, electric power consumed by a system for water heating is reduced, and meanwhile, the solar water heater and the buried-pipe heat collector are used, so that the problem that the efficiency of a ground source heat pump is reduced after usage for a certain period is solved.

Description

technical field [0001] The invention relates to the field of leather drying devices, in particular to a double-side blowing type leather processing equipment. Background technique [0002] Drying is an extremely important process in the leather finishing process. The dyed leather should be squeezed and stretched for the first drying. At present, the commonly used drying method is to first use iron plate or vacuum drying to reduce the moisture content of the leather to 35-42%, and then dry it naturally or in a drying room to further reduce the moisture content of the leather to about 15%. Enter the next process. For the drying in the back, most factories use hanging to dry naturally, and the drying time takes about two days. The drying time is very long, which seriously affects the leather processing efficiency. When the leather is dried by blowing hot air, the moisture of the leather is taken away by the hot air. At present, the hot air with moisture is mostly discharged d...

AI Technical Summary

Problems solved by technology

In the latter part of the drying process, most factories use hanging to dry naturally, and the drying time takes about two days. The drying time is very long, which seriously affects the leather processing efficiency.

When the leather is dried by blowing hot air, the moisture of the leather is taken away by the hot air. At present, the hot air with moisture is mostly discharged directly, which leads to the waste of heat energy. There is also a method of recovering this part of air heat energy by setting a heat exchanger. , but the recovery rate is very low, and the waste of heat energy cannot be avoided
