Steel belt type rotary cutter discharging efficient slag filter cake drying machine

Abstract

The invention discloses a steel belt type rotary cutter discharging efficient slag filter cake drying machine. The steel belt type rotary cutter discharging efficient slag filter cake drying machine comprises a heat conducting oil furnace, a rotary cutter discharging machine, a steel belt and a drying machine body; the interior structure of the drying machine body is that a flat plate heating body is arranged below the steel belt; fin heating bodies on the steel belt are in series connection through connecting pipes; a motor drives a fan; two ends of the drying machine body are provided with flexible material doors; a rotary cutter discharging machine comprises a feeding hopper, a cutter blade and a rotary cutter frame; the feeding hopper is provided with a flexible baffle plate with the adjustable opening degree; the flexible baffle plate which is fixed through a hinge is supported by a spring; a vibrator is arranged on the flexible baffle plate; a rotary shaft, a rotary disc and the cutter frame are welded to form into the rotary cutter frame; the cutter blade is fixed on the cutter frame through bolts. According to the steel belt type rotary cutter discharging efficient slag filter cake drying machine which is efficient and energy saving, the drying is rapid in speed and through, and continuous efficient drying of slag filter cakes is achieved; the motor reduces speed to drive the rotary cutter to cut and discharge and tile materials are particularly suitable for rapid and efficient drying; the integral system is coordinate and smooth in design and stable and reliable in working.

Description

technical field [0001] The invention relates to a slag filter cake dryer, in particular to a high-efficiency slag filter cake dryer for steel belt rotary 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 reduction an...

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
