Steel belt type reciprocating cutter feeding efficient slag filter cake drying machine

Abstract

The invention discloses a steel belt type reciprocating cutter feeding efficient slag filter cake drying machine which comprises a heat conduction oil furnace, a reciprocating cutter feeding machine, a steel belt and a drying machine body. The inner structure of the drying machine body is characterized in that flat plate heating bodies are arranged below the steel belt, steel belt upper fin heating bodies are serially connected through connecting tubes, and motors drive fans. Movable material doors are disposed at two ends of the drying machine body. The reciprocating cutter feeding machine comprise a feeding hopper, a crank, a connecting rod, a cutter hanging rod and a cutter, wherein the crank drives the connecting rod to allow the cutter to move in a reciprocating manner, the cutter comprises a cutter plate and a cutter rack, a frame and a rib plate form the high-strength cutter rack, the cutter plate is welded to the cutter rack through spot welding, and cutter holes are formed in the cutter plate. The drying machine has the advantages that the drying machine is efficient and energy saving, fast and through in drying, and capable of achieving continuous and efficient drying of slag filter cakes; the crank connecting rod mechanism drives the reciprocating cutter to perform cutting and feeding, and tile-shaped materials are especially suitable for fast and efficiency drying; the drying machine is coordinated and smooth in system overall design and stable and reliable in work.

Description

technical field [0001] The invention relates to a slag filter cake dryer, in particular to a high-efficiency slag filter cake dryer with steel belt reciprocating knife cutting. Background technique [0002] Hydrometallurgy is a processing and utilization method in which the ore is ground into powder and then leached. The slag after leaching is press-filtered and mainly exists in the form of filter cake. Due to the generally large amount of ore processing, a large amount of waste is produced. Slag filter cake, if a large amount of slag filter cake is randomly piled up and discharged, it will cause serious pressure and adverse effects on the environment. Therefore, it is very important to comprehensively utilize the slag filter cake to achieve energy saving and emission reduction and improve economic benefits. [0003] After the slag filter cake is dried, compound fertilizer can be produced, which can be absorbed and metabolized by crops to achieve energy saving, emission redu...

Problems solved by technology

[0004] Therefore, drying the slag filter cake is the first step to realize slag turning waste into treasure and ecological comprehensive utilization. Although there are many types of dryers available, there are almost no dryers specifically for slag filter cake. Filter cakes are generally large, thick, and have special physical and chemical properties. Some slag filter cakes are even as thick as 1 square centimeter. Existing dryers often have high energy consumption and low efficiency when used for slag filter cake drying. , incomplete drying and inconvenient continuous operation, therefore, the existing dryers cannot meet people's requirements for slag filter cake drying, and need to be redesigned according to the characteristics of slag filter cake
