Abstract

The utility model discloses a water-air double-heating dryer. A sealing box is fixed on a bracket, and a heating device is arranged in the sealing box as a main heating source; a roller is arranged in the sealing box and a support for supporting the roller Roller and transmission mechanism; one end of the sealed box is provided with a feed hopper and a hot air inlet pipe, and the hot air inlet pipe is used as an auxiliary heating source; the other end is provided with a discharge port and a humid air discharge port. The utility model can reduce the heat energy of the hot air channel, so that the hot air channel is mainly used to accelerate the flow of water vapor in the drum instead of the main heat source. It is beneficial to increase and preserve the heat in the drum, avoiding the direct discharge of high-temperature hot air, and achieving the effect of improving drying efficiency and reducing heat energy loss.

Description

Water and air double heating dryer

technical field

The utility model relates to the technical field of biomass energy utilization, in particular to a water-air double heating dryer.

Background technique

Existing material dryers usually use hot air to heat the inside of the drum and at the same time blow off the humid air to achieve the purpose of drying. However, there are the following defects: 1. The hot air temperature needs to be high, otherwise the drying purpose cannot be achieved, or the length of the drying cylinder needs to be extended, and the drying efficiency is low and the effect is not good; 2. In order to achieve the effect of quickly dissipating the water vapor, the hot air flow The higher the speed, the higher the hot air is directly discharged, resulting in a lot of waste of capacity.

Utility model content

The utility model provides a water-air dual-heating dryer, which can improve the drying effect and reduce the temperature of the hot air as much as possible to achieve the purpose of energy saving.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a water-air double heating dryer, including a roller on the bracket, and a roller for supporting the roller, a transmission mechanism and a power mechanism, and the two sides of the roller The ends are respectively provided with end walls fixed on the bracket, and the roller and the end walls are frictionally fitted and sealed; there are hot water supply pipes connected between the two end walls, and the two end walls are respectively provided with hot air inlets and hot air outlets. It is isolated from the inner cavity of the drum, and the heating air pipe is connected with the inner cavity of the drum; a water pump and a fan are respectively installed on the hot water supply pipe and the hot air inlet. Heat collecting covers are respectively arranged at both ends of the hot water supply pipe.

The beneficial effect is: the utility model uses the hot water supply pipe as the main heating source, and the hot air as the auxiliary heating source for promoting the water vapor flow in the drum, thereby reducing the heat energy of the hot air channel. Not only is it beneficial to increase and preserve the heat in the drum, but it can also prevent the high-temperature hot air from being discharged directly, thereby achieving the effects of improving drying efficiency and reducing heat loss.
