Embodiment 1

[0032] See attached Figure 1-2 , a horizontal multi-axis disc dryer comprising: a housing 1 provided with a feed port 8, a discharge port 10 and an exhaust port 9; the first and second drying layer units, including a Drying disc shaft 3, the drying disc installed on the drying disc shaft 3 and the pushing plate 5 installed on the outer circumference of the drying disc; and the power transmission mechanism 2 for rotating the drying disc shaft 3; wherein, The first and second dry layer units are installed in the housing 1, and a spacer 4 and a material channel 11 adjacent to the spacer 4 are arranged between the first and second dry layer units, so as to The material to be dried passes through the feeding port 8 , the first drying layer unit, the material channel 11 , and the second drying layer unit to the discharge port 10 in sequence.

[0033] Preferably, the horizontal multi-shaft disc dryer may further include a scraper 6 installed between each drying disc for scraping of...

Embodiment 2

[0046] The structure of the horizontal multi-shaft disc dryer in this embodiment is basically the same as that in Embodiment 1, and the similarities are omitted here, and the differences will be mainly described below.

[0047] See attached image 3 And attached Figure 4 , the horizontal multi-shaft disc dryer also includes one or more drying layer units, and spacers 4 and material passages 11 adjacent to the spacers are arranged between all drying layer units, and the material passages 11 alternately They are arranged on the right and left sides of the corresponding spacer so that the material to be dried can pass through the drying layer unit and reach the discharge port 10 smoothly.

[0048] Preferably, the horizontal multi-shaft disc dryer may include: a housing 1, 6 power transmission mechanisms 2, 6 drying disc shafts 3, 2 spacers 4, a pusher plate 5 and a scraper 6, wherein, 6 drying disc shafts 3 are stacked up and down two or two to form three layers (upper, middle...

Abstract

The invention provides a horizontal multi-shaft disc dryer, which comprises a shell (1), first and second drying layer units and a power transmission mechanism (2), wherein the first and second drying layer units comprise drying disc shafts (3) used for heating a material to be dried, drying discs arranged on the drying disc shafts, and material push plates (5) arranged on the outer circumferences of the drying discs; the power transmission mechanism (2) is used for rotating the drying disc shafts; the first and second drying layer units are arranged in the shell (1); and a clapboard and a material channel adjacent to the clapboard are arranged between the first and second drying layer units so as to allow the material to be dried to reach a discharging port through a charging port, the first drying layer unit, the material channel and the second drying layer unit. The dryer can further comprise one or more drying layer units. The dryer dries materials through drying layer units stage by stage so as to improve the thermal efficiency of drying.

Description

technical field [0001] The invention relates to the field of material drying, in particular to a horizontal multi-shaft disc dryer with multiple drying disc shafts. Background technique [0002] The disc dryer is widely used in the drying of coal slime, sludge, fish meal, graphite, carbon black, polyethylene powder, feed, distiller's grains and other materials. Compared with other types of dryers, it has the following advantages: [0003] 1) The surface of the heat transfer disc is smooth, not easy to scale, not easy to wear, and has good heat transfer performance. [0004] 2) The inner rotor of the dryer is submerged in the material, and the heat transfer area is fully utilized. [0005] 4) The drying project is closed and operated without air pollution. [0006] 5) The equipment runs smoothly, and the operation and maintenance are simple; it can be operated continuously or intermittently. [0007] For example, the applicant is Wang Shaoliang, and the patent application ...
