Description

Automatic temperature control device of flitch dryer

Technical Field

The invention relates to an automatic temperature control device of a flitch dryer, belonging to the field of leather processing.

Background

The leather flitch is an auxiliary facility of one of the procedures in the leather making process, the main function of the facility is the drying and shaping of the dyed leather, and most of the equipment used for drying and shaping the leather is a vacuum drier. The vacuum dryer has high manufacturing cost, large energy consumption and high maintenance and operation cost, and can not finish the production process which accords with all leather products. Some leather products need to be dried and shaped, and do not need to be vacuumized, otherwise the quality of the products can be influenced, and although some iron plate type equipment is also available, the leather products are easy to be heated unevenly due to large size and cause damage to the leather due to overhigh temperature.

Disclosure of Invention

the outer surface of the triangular barrel is provided with a temperature sensor, the temperature sensor is electrically connected with a PLC, and the PLC is electrically connected with a valve.

The vapor that produces the boiler through steam conduit spreads into three-edged bucket into inside, because the inside water that fills of three-edged bucket, can heat the inside water of three-edged bucket, three-edged bucket surface generate the temperature, add hot water through vapor, conduct the mode on three-edged bucket surface again, the heating is even, therefore, the carrier wave prepaid electric energy meter is low in cost, vapor is through the inside back of three-edged bucket simultaneously, meet cold, inside vapor can condense into the comdenstion water, steam conduit flows into the cistern with the comdenstion water, the cistern passes through the water pump with comdenstion water suction header tank, the header tank passes through inlet channel and connects three-edged bucket top, be used for replenishing the inside water of three-edged bucket, guarantee that the inside water of three-edged bucket is full.

The temperature of the surface of the triangular barrel is detected through a temperature sensor, and when the temperature is lower than 75 ℃, a valve is controlled to be opened through a PLC. Steam enters the triangular barrel to heat water to 75 ℃, and then the valve is controlled to be closed through the PLC, so that air supply is automatically stopped; the temperature of the triangular barrel is ensured not to exceed 75 ℃. Prevent the leather from being dried rapidly, reduce the leather yield, cause the problems of the deformation of the veneer due to long-time high temperature and the like

Preferably, the part of the steam pipeline positioned inside the triangular barrel is spiral.

The contact area can be effectively increased.

Preferably, the height of the water collecting tank is higher than that of the triangular barrel.

Through gravity, the water in the water collecting tank is automatically supplemented into the triangular barrel.

Preferably, the triangular barrel is made of iron.

Good heat conductivity

Preferably, an exhaust pipe is arranged on the triangular barrel.

The vapor generated in the triangular barrel is discharged, so that the triangular barrel is prevented from deforming or even causing danger due to overlarge internal pressure.

The invention has the beneficial effects that:

(1) the steam generated by the boiler is transmitted into the triangular barrel through the steam pipeline, and the triangular barrel is filled with water, so that the water in the triangular barrel can be heated, the surface of the triangular barrel generates temperature, and the water is heated through the steam and then transmitted to the surface of the triangular barrel, so that the heating is uniform, and the cost is low;

(2) simultaneously vapor is through the inside back of three-edged bucket, can meet cold, and inside vapor can condense for the comdenstion water, and steam conduit flows into the cistern with the comdenstion water, and the cistern passes through the water pump with comdenstion water suction header tank, and the header tank passes through inlet channel and connects three-edged bucket top for supply the inside water of three-edged bucket, guarantee that the inside water of three-edged bucket is full of the state, three-edged bucket surface all can be heated, can circulate again and use.

(3) An exhaust pipe is arranged on the triangular barrel; the vapor generated in the triangular barrel is discharged, so that the triangular barrel is prevented from deforming or even causing danger due to overlarge internal pressure.

(4) Detect the temperature on triangular barrel surface through temperature sensor, prevent that the leather from drying sharply, the leather rate reduces, and long-time high temperature leads to flitch deformation scheduling problem.
