Peristaltic propulsion type drying equipment

Abstract

The invention discloses peristaltic propulsion type drying equipment. The peristaltic propulsion type drying equipment comprises a heat supply module, a drying chamber and a material conveying devicearranged in the drying chamber, wherein the drying chamber is provided with a heat source inlet, a heat source outlet, a material inlet and a material outlet; a heat source of the heat supply module is arranged at the position of the heat source inlet and used for providing a heat source for the drying chamber; the material conveying device is used for providing a platform for horizontally pavingmaterials and pushing materials, and comprises two or more groups of grid strips which are laminated at intervals to form a laminated propelling type material conveying platform; a gap is formed between every two adjacent grid strips; and when the materials are conveyed forwards, the ventilation gaps are kept smooth, and the advancing materials are repeatedly overturned. According to the peristaltic propulsion type drying equipment, in the material conveying process, the interactive grid strips generate the transparent gaps, so that the mobility of air is improved, and the materials are advantageously dried.

Description

【Technical field】 [0001] The invention belongs to the technical field of material drying equipment, and specifically refers to a peristaltic propulsion drying equipment. 【Background technique】 [0002] Material drying equipment is widely used in the drying process of chemical, food, medicine, building materials and other industries. In the field of sludge treatment, the mud cake produced by the sludge dewatering machine falls freely to the mesh crawler belt after being granulated or slivered, and is transported by the multi-layer reciprocating mesh belt, and the mud cake on the mesh belt gradually evaporates. Finally, a material discharge with a lower moisture content is formed. [0003] Chinese invention patent 201810369116.0 discloses a return air circulation heating and drying device, and Chinese invention patent 201810953665.2 discloses a closed belt dryer. The material conveying devices in these two patent documents both use conveyor belts to convey materials, and the ...

AI Technical Summary

Problems solved by technology

[0004] This kind of drying equipment in the prior art has the following disadvantages: 1. The drying efficiency of mud cakes that cannot be molded with high moisture content is extremely low

2. After the mud cake falls to the mesh belt, it cannot be spread evenly in a short time, and it often accumulates together, and even blocks the ventilation mesh of the filter on the mesh belt, affecting the effect of ventilation and evaporation

3. During the conveying process, the shape of the mud cake will not change, the moisture inside the mud ball cannot be discharged, and the mud ball at the bottom cannot always be in contact with the hot air during a conveying process, resulting in uneven evaporation

4. The hot air rises vertically from the bottom, and there is no horizontal hot air. For the sludge on the mesh belt, the evaporation efficiency is not high

5. Since the discharge port is open, hot air will leak from the discharge port, increasing heat loss
