Spliced ​​multi-edge sand cone and three-pass sand drying machine with the sand cone

Abstract

The invention discloses a spliced ​​multi-edge sand-discharging cone; it relates to the field of sand-drying machine equipment, including a sand-discharging pyramid, the top of which is sealed with a polygonal observation hole cover, and the sand-discharging pyramid includes multiple spliced ​​pieces The sand outlet pyramid flap, the outer plate surface of the sand outlet pyramid is provided with a sand outlet pyramid partition at the corresponding ridge line position, and a sand falling channel is formed between two adjacent sand outlet pyramid partition boards and the sand outlet pyramid flap; splicing The advantage of the multi-edged sand outlet cone is that when wear occurs, the spliced ​​multi-edged sand outlet cone can be disassembled into multiple single-edged sand outlet cones, and each new single-edged sand outlet cone is bent Parts can be transported into the dryer barrel through the kiln head hole for assembly, and there is no need to cut and weld the sealing plates at both ends of the dryer; in actual work, the multi-edged sand cone partition is a component with relatively large wear and tear Multiple anti-friction strips are set on the surface to realize sanding instead of sanding steel and improve its service life.

Description

technical field [0001] The invention relates to the field of sand drying equipment, in particular to a sand cone partition with wear-reducing strips. Background technique [0002] With the continuous development of industrialization, the dryer, as an efficient drying equipment, is widely used in the drying of materials such as sand and mortar. For the implementation of the optimal ratio of cement, the country has promoted the construction of construction dry powder ready-mixed mortar stations with good environmental protection effects in recent years. One of the raw materials used in the dry powder ready-mixed mortar station is dry sand, which requires the use of a wet sand dryer. Initially, the single cylinder dryer was used in the industry. Due to its poor drying effect, large heat loss and high energy consumption , with low output, it was quickly replaced by three-pass dryers. However, due to the structure of the three-pass sand dryer (three-cylinder sand dryer), most o...

Problems solved by technology

[0003] The purpose of the present invention is to provide a spliced ​​multi-edge sand cone and a three-pass sand dryer with the sand cone, aiming at improving the problem that the existing three-pass dryer components are difficult to replace after the parts are worn out, and at the same time through The wear-reducing strip realizes sanding instead of sanding steel to improve the wear life of the grinding surface of the sand cone separator
