Embodiment Construction

[0030] Now in conjunction with accompanying drawing, the present invention is described in further detail.

[0031] Such as figure 1 , figure 2 , image 3 and Figure 4 The shown exhaust heat utilizes hot air penetrating countercurrent dryer, which includes a dryer box 21 and an induced draft fan A. The two ends of the dryer box 21 are respectively provided with an exhaust hood 13 and an air intake hood 17, and the exhaust hood 13 is connected to the induced draft fan. A, the induced draft fan A is tangentially connected to the high-efficiency cyclone dust removal tail heat recovery device formed by the superimposition of the tube-and-tube heat exchanger 4 and the cyclone dust collector 1, and then emptied; the shell-side inlet end of the tube-and-tube heat exchanger 4 is connected to the blower 9. The air outlet end is connected to the air inlet hood 17 through the steam fin heater 10; the induced draft fan A includes a fan impeller 41 and a casing 45, and the fan impelle...

Abstract

The invention discloses a tail heat utilization hot wind type penetrating reverse flow dryer. A draught hood and an air inlet cover are arranged at the two ends of a dryer box body respectively. The draught hood is connected with an efficient cyclone dust removal tail heat recoverer in the tangent direction through an induced draught fan and is then emptied. An air blower is connected with the air inlet cover through a tube type heat exchanger and a steam fin heater. An impeller of the induced draught fan is of the structure that blades are in hollow wedge shapes and a back plate is in a dish shape. The appearance contour line of the induced draught fan is an involute. According to the tail heat utilization hot wind type penetrating reverse flow dryer, the efficient cyclone dust removal tail heat recoverer is designed by innovatively integrating tail heat utilization and dust removal, and therefore the device input is reduced, and the work efficiency is improved; by means of the induced draught fan, a soft partition plate and an axial flow fan, penetrating type reverse flow drying is ingeniously achieved, and the work efficiency is improved; and by means of the structure that the blades are in the hollow wedge shapes and the back plate is in a dish shape, dust on the impeller is removed in real time, the strength of the impeller of the draught fan is improved, stability is enhanced, accidents caused by dust accumulation are effectively eradicated, and application prospects are wide.

Description

technical field [0001] The invention relates to a drying machine, which specifically refers to a hot air type penetrating countercurrent drying machine which utilizes the tail heat of a fan without dust accumulation. Background technique [0002] Due to its mature technology, strong adaptability, low operating cost and strong reliability, the hot air dryer is still one of the main preferred equipment for drying materials. If the material can be penetrated and countercurrently dried during the hot air drying process, And the effective recovery of tail heat is of special significance for improving drying efficiency and realizing energy saving and emission reduction. [0003] The induced draft fan is the key equipment of the hot air dryer. The induced draft fan is generally a centrifugal fan. The continuous, stable and reliable operation of the induced draft fan is very important for the dehumidification of the dryer. Because most of the occasions where the dryer is used contai...
