Abstract

The invention discloses a helical blade drying machine, which comprises an outer shell and a central rotating shaft which is arranged inside the outer shell, and the helical blade drying machine is characterized in that a helical blade is sleeved on the central rotating shaft, the outside of the helical blade is uniformly provided with heating units, one end of the central rotating shaft is provided with a drive device, and the drive device is fixed on one end of the outer shell. By adopting the heating units and the helical blade, the energy loss in the process for heating the heat conduction oil can be reduced, and the utilization rate of the energy can be increased.

Description

A spiral blade dryer

technical field

The invention relates to a sludge drying device, in particular to a spiral blade dryer.

the

Background technique

The rotary disc dryer uses heat transfer oil to dry the sludge. The drying process requires a large amount of heat transfer oil, and heating the heat transfer oil consumes a lot of energy, which causes unnecessary waste.

Contents of the invention

The invention aims at the deficiencies of the prior art, and provides a spiral blade dryer which directly dries the sludge by a heating unit, which can improve the energy utilization rate.

For realizing above technical purpose, the present invention will take following technical scheme:

A spiral blade dryer, which includes a shell and a central rotating shaft arranged in the shell, characterized in that: the central rotating shaft is covered with a spiral blade, and a heating unit is evenly distributed outside the spiral blade, and one end of the central rotating shaft is provided with There is a driving device, the driving device is fixed at one end of the casing, the driving device is a geared motor, the central rotating shaft is connected to the driving device with a coupling, and the casing is provided with a material inlet, a material outlet and an exhaust port .

Beneficial effects of the present invention: the device adopts a heating unit and a helical blade, which reduces energy loss in the process of heating the heat transfer oil and increases the utilization rate of energy.

Detailed ways

The accompanying drawing discloses a non-restrictive structural schematic diagram of a preferred embodiment involved in the present invention, and the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, a spiral blade dryer according to the present invention includes a casing 6 and a central rotating shaft 2 disposed inside the casing 6, and is characterized in that: the central rotating shaft 2 is covered with a spiral blade 3, the spiral The heating unit is evenly distributed on the outside of the blade 3, and one end of the central rotating shaft 2 is provided with a driving device 1, and the driving device 1 is fixed on one end of the casing 6. The driving device 1 is a geared motor, and the central rotating shaft 2 and the driving device 1 are used The casing is connected by a coupling, and the housing is provided with a feed port 5, a discharge port 7 and a steam discharge port 4.

Its working process is as follows: the driving device 1 drives the central rotating shaft 2 to rotate, the heating unit generates heat, and the sludge is poured into the dryer from the feeding port 5 . The steam emitted during the drying process will be discharged through the steam discharge port 4, and the dried sludge will be sent out from the discharge port 7.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection of the present invention. within range.
