Embodiment 1

[0063] This embodiment provides a drying device for making slime strips, see Figure 1 to Figure 2 , comprising an extruding assembly, a drying assembly located below the extruding assembly, and a sliver-making orifice 4 between the extruding assembly and the drying assembly, wherein the extruding assembly includes an extruding cylinder 1 and a piston located in the extruding cylinder 1 2. The drying assembly includes a drying cylinder 3 and an air supply unit for supplying dry gas to the drying cylinder 3. The space between the piston 2 and the sliver orifice 4 in the extrusion cylinder 1 is an extrusion cavity, and the inside of the drying cylinder 3 is The drying chamber and the extrusion chamber are connected to the feed pipe 5, and the drying cylinder 3 is connected to the discharge pipe 6; that is to say, along the vertical direction, the piston 2, the extrusion chamber, the sliver orifice 4, and the drying chamber are arranged in sequence.

[0064] It should be noted th...

Embodiment 2

[0088] The present embodiment provides a kind of coal slime drying method, comprises the following steps:

[0089] Step 1: Feed of Slime

[0090] Open the feeding pipe, and the coal slime enters the extrusion chamber from the feeding pipe. When the coal slime in the extrusion chamber reaches a certain thickness, close the feeding pipe;

[0091] Step 2: Compression cutting and extrusion drying of slime

[0092] When the piston is opened, the piston moves to the direction of the orifice plate, the volume of the extrusion chamber gradually decreases, the piston squeezes the slime, and under the action of pressure, the coal slime passes through the sliver hole of the orifice plate to complete the compression cutting of the slime and extruding and drying to obtain slime strips, and the piston resets;

[0093] Step 3: Drying of slime strips

[0094] The slime strips formed by extrusion are hung vertically under the strip-making orifice and in the drying chamber. The air supply un...

Abstract

The invention discloses a drying device and method for making slime strips, which belongs to the technical field of drying high-viscosity slime, and solves the problems of high energy consumption, high cost and poor effect in the drying process of slime in the prior art. The device of the present invention comprises an extruding assembly, a drying assembly positioned below the extruding assembly, and a strip-making orifice between the extruding assembly and the drying assembly; the extruding assembly includes an extruding cylinder and a piston positioned in the extruding cylinder, and the drying The assembly includes a drying cylinder and an air supply unit for supplying dry gas to the drying cylinder. The space between the piston and the sliver orifice in the extrusion cylinder is the extrusion chamber, and the inside of the drying cylinder is the drying chamber. The extrusion chamber and the feed pipe Connected, the drying cylinder is connected with the discharge pipe. The method of the invention is feeding of coal slime→compression cutting and extrusion drying of coal slime→drying of coal slime strips. The device and method of the invention can be used for making and drying coal slime.

Description

technical field [0001] The application belongs to the technical field of drying high-viscosity coal slime, and in particular relates to a drying device and method for making strips of fine-grained high-viscosity coal slime. Background technique [0002] According to the process and application of coal slime recycling, the physical properties of coal slime vary. At present, a filter press is usually used to recover the coal slime. [0003] However, the coal slime recovered by the filter press usually requires a water content of about 20% to 24%. If the water content of the coal slime is too high, it will not only affect the price of the coal slime, but also affect the sales of the coal slime. The existing coal slime drying treatment has problems such as high energy consumption, high cost, and poor effect. Contents of the invention [0004] In view of the above analysis, the present application aims to provide a drying device and method for making slime, which solves the p...
