How to avoid the phenomenon of air leakage in the box dryer

Box-type dryer using double-track conveyor eliminates damage to the material surface phenomenon, through two-way cross-flow mode, the cloth spread adjustable, feed device to increase both other measures to ensure a uniform product moisture, the drying temperature, the material The residence time and the thickness of the material layer can be intelligently controlled by the computer. Since 50%-95% of the hot air can be recycled and the insulation box is used, the energy consumption and production cost are reduced, and the bottom is provided with an automatic cleaning mechanism for automatic cleaning. All are manufactured according to the standard. All the plates are laser-cut and cut to prevent the deformation of the body due to manual cutting. It is suitable for the drying treatment of high-grade puffed pellets and pet feed. It can also be used in food, food and chemical industries. Drying of granular and flaked materials.

The principle of the box dryer:

The clean hot air is distributed into the bed through the valve plate; the wet material entering from the feeder is boiled by hot air. Due to the extensive contact between hot air and materials; the process of heat and mass transfer is enhanced; therefore, it can be dried in a short period of time. It enters from one end of the bed and is boiled and dried for several tens of seconds to several minutes, automatically flowing out from the other end of the bed. The box dryer is suitable for heating, solidifying, drying and dehydrating materials and products in the pharmaceutical, chemical, food, agricultural and sideline products, aquatic products, light industry, heavy industry and other industries. Such as bulk drugs, raw drugs, Chinese herbal medicine pieces, extracts, powders, granules, granules, water pills, packaging bottles, pigment dyes, medicinal materials, dehydrated vegetables, aquatic products, fruit slices, sausages, plastic resins, electrical components, baking varnish, etc.

The box dryer needs to avoid air leakage during operation:

The box dryer is operated by the hot gas generated by the combustion furnace, and the circulating flow of hot air in the machine is inseparable from the exhaust system, which can quickly suck the high temperature gas generated by the combustion furnace into the drum interior. It allows rapid exchange of heat with the drying material, and the exhaust system can also quickly discharge the exhaust gas in the drum, so that the drying effect can be quickly achieved. However, the design of the exhaust system must be tight and airtight. However, after a long period of operation, the air leakage is inevitable. The staff should pay special attention to the air leakage between the flaps and the bearing parts.

During the operation of the machine, the staff should prevent the large slag block, bricks, wire and other debris from falling into the flap valve to cause air leakage, even obstructing the discharge or jamming the flap, and cannot be turned over. Observe how much the flap valve is cut and the size of the blanking interval, and whether it is compatible with the discharge speed of the box dryer . In the dump bucket, it is impossible to store too much material to affect the discharge, and it is not necessary to store too little vibration. Refuel the shaft oil cup on time, twist l-2 times per shift, and rotate the silver one button. For the flashing valve, it is necessary to observe whether the operation is flexible, whether the unloading is smooth, whether the balance hammer is properly positioned, and whether the triangular cone is in close contact with the discharge nozzle. According to the situation of ash deposition, the balance hammer can be properly adjusted, and the triangular pyramid is usually movably coupled to the lever.
