Problems solved by technology

The rake-type vacuum dryer mentioned above is not suitable for drying lithium iron phosphate materials. This is due to the poor fluidity of lithium iron phosphate suspended materials. When drying, the materials change from liquid to paste to powder, and the material changes greatly. It is sticky, and the working resistance of the rake teeth is very large. For example, the rake rod and the rake teeth are not stro...

Embodiment 1

[0019] See Figure 1 to Figure 6 , This embodiment includes a motor 21, a reduction box 22, a saddle base 24, a jacketed tank body 1 disposed on the saddle base 24 and a main shaft 6 inside the tank body 1. The output shaft of the reduction box 22 is connected with the above-mentioned main shaft 6 through a chain drive or a belt drive.

[0020] For the convenience of maintenance and cleaning, the top of the tank body is provided with a manhole b with a length greater than 1 / 2 of the length of the tank body. The manhole b is provided with a manhole cover 15 that can be opened and closed quickly. There is a feeding port a, the feeding port a is connected with a feed port cover plate 14 that can be opened and closed quickly, and the vacuum tube 16 is connected on the manhole cover plate 15 .

[0021] The left and right sides of the jacket of the tank body 1 are respectively provided with a set of circulating oil pipes 11, the bottom sides of the tank body 1 are respectively prov...

Abstract

The invention relates to a rake vacuum drying main machine, which comprises a tank body, wherein a main shaft of the main machine is solid, and a plurality of rake tooth components are arranged on the main shaft; each rake tooth component consists of a sleeve shaft and four solid rake teeth which are distributed and fixed on the sleeve shaft uniformly and is connected on the main shaft by a sleeve shaft key; the orientations of the rake teeth of all rake tooth components are the same, so that four channels are formed in the tank body; and a knocking rod is arranged in each channel or the spaced channel. In the rake vacuum drying main machine, materials are knocked continuously inside the tank body of the drying main machine by utilizing the knocking rods to accelerate the crushing of the materials, so that the materials have the large specific surface area, the drying process is accelerated, finished products are uniform in fineness and low in moisture; and the rake vacuum drying main machine is suitable for drying lithium iron phosphate materials, and improves the quality and drying efficiency of the products.

Description

technical field [0001] The invention relates to a rake-type vacuum drying host. Background technique [0002] The rake vacuum dryer is a general-purpose drying equipment. The rake vacuum dryer is a device that uses the characteristic that the boiling point of the water in the material decreases under vacuum to dry. The equipment is indirectly heated with a steam jacket, and the water is evaporated by heating and extracted in time. Inside the dryer shell, the rake teeth are driven by the transmission shaft. The end of the rake teeth and the axis are designed to have a certain angle. The transmission shaft rotates in the forward and reverse directions to move the material along the axial direction to facilitate drying and discharging. The Chinese Invention Patent Publication No. 101050916A discloses a rake dryer, which mainly adopts a hollow main shaft to be installed in the inner cylinder of the tank. The two ends of the hollow main shaft are respectively equipped with bea...
