Description

Efficient dryer for axial air inlet and axial air exhaust of clean room

Technical Field

The utility model relates to the technical field of dryers, in particular to an efficient dryer for axial air inlet and axial air exhaust of a clean room.

Background

The drying principle of the existing dryer is as follows: heating air to 70-80 deg.c with heater, heating and taking away water from clothes, filtering the wet and hot air with filter to eliminate impurity, and exhausting air with exhaust fan. Therefore, the dried hot wind is indispensable as a medium for drying laundry. From market application, the mode of hot air entering the inner roller is mainly as follows: radial air inlet and radial air exhaust are shown with reference to figure 1. The largest disadvantage of the air inlet mode is that the hot air enters the inner roller and rotates at the same time, the wall of the inner roller can reflect and rebound a part of hot air, a part of hot air is wasted, and the air inlet quantity and the drying efficiency of the inner roller are reduced;

based on this, chinese patent publication No. CN103103735B discloses a negative pressure type front door air intake dryer, the working principle of which is shown with reference to fig. 2, in which hot air enters from one axial end of an inner drum and is radially discharged. Although the air inlet mode can improve the air inlet quantity of the inner roller, moist hot air is remained in the inner roller due to the influence of reflection on the inner wall of the inner roller when the air is exhausted, and the drying efficiency is also influenced.

Detailed Description

The principles and features of the present utility model are described below with reference to fig. 1 through 3, the examples being provided for illustration only and not for limitation of the scope of the utility model.

An axial air inlet and axial air exhaust efficient dryer for a clean room comprises an outer cylinder body 1, an inner cylinder body 2, a clothes door 3 and a transmission system 4.

The inner cylinder body 2 is rotatably connected to the inner part of the outer cylinder body 1, one end of the inner cylinder body 2 is connected with a belt wheel, the transmission system 4 at least comprises a motor 14 and a belt 15, the output end of the motor 14 is connected with the belt wheel, and the motor 14 drives the inner cylinder body 2 to rotate through the belt 15.
