Problems solved by technology

[0006] The present invention provides a tandem jig system that improves the efficiency of slag sorting in domestic waste incineration, one purpose of which is to have the function of improving the working efficiency of the equipment and solve the traditional non-magnetic heavy metal recovery process in the comprehensive utilization of slag. Generally, the recovery process of primary jigging + secondary jigging + shaking table is adopted. The structure of the shaking table is more complicated, the operation is not convenient, the maintenance rate is extremely high, and the productivity is also low, which affects the working efficiency of the equipment; One purpose is to solve the problem that in the recovery process of primary jigging + secondary jigging + shaker, the equipment occupies a large area of ​​the plant, which leads to an increase in the cost of the equipment, so as to reduce the occupied area of ​​the equipment and reduce the cost of the equipment.

Embodiment 1

[0030] Such as Figure 1-3 As shown, the present invention provides a tandem jig system improving the efficiency of domestic waste incineration slag sorting. The series jigger system improving the efficiency of domestic waste incinerator slag sorting comprises the following steps:

[0031] Step 1, feeding materials to the series jig system;

[0032] Step 2, performing a series process of first-stage jigging A and second-stage jigging B on the feed;

[0033] Step 3: Carry out three-stage fine jump recovery jigging.

Embodiment 2

[0035] Such as Figure 1-3 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: Preferably, step 2 also includes the following steps: the sawtooth wave waveform first rises in a straight line, then falls sharply, rises again, and then falls steeply, so Repeatedly, and then use water as the beneficiation medium, sort according to the specific gravity (density) difference between the useful minerals and the gangue, discharge the slag from the side plate of the first jigging A, and discharge the first-grade concentrate at the bottom of the first jigging A Ore discharge A1, the first-level concentrated ore discharge A1 enters the top of the second-level jigger B, and cooperates with the second-level jigger to operate and sort, so that the side plate of the second-level jigger B performs slag discharge, and then the second The bottom of the second jigging B carries out secondary concentrate discharge B1.

Embodiment 3

[0037] Such as Figure 1-3 Shown, on the basis of embodiment 1, the present invention provides a kind of technical scheme: preferably, in step 3, also include the following steps: adopt two special-purpose drum jigs of one square cascaded into two squares, carry out The sieve hole is optimized for three-stage fine jumping recovery jig C, and a special iron ore cushion is laid on the sieve surface, and the tailings are directly discharged into the closed-loop beneficiation. The top pressure drives the spring to press down, and then goes up through the reset of the spring, and cooperates with the resilience of the flexible connection tympanic membrane to sort the ore inside the tympanic chamber, the tailings are directly discharged into the closed-loop mineral processing, and the concentrate is separated through the three-stage sand settling water bucket The final water is directly discharged, and the concentrate in the sedimentation bucket is directly recovered from copper sand...

Abstract

The invention discloses a tandem type jigger system capable of improving sorting efficiency of household garbage incineration slag, and relates to the technical field of jiggers. The system comprises the following steps: 1, feeding material into the tandem type jigger system, 2, carrying out a first-stage jigging A and second-stage jigging tandem process on the fed material, 3, carrying out third-stage concentrate recovery jigging, sawtooth waves firstly rise in a straight line, then steeply fall, then rise and then steeply fall, and the process is repeated, so that water is used as a mineral separation medium, and separation is carried out according to the specific gravity (density) difference of useful minerals and gangue. According to the system, a third stage uses two special one-square-meter jiggers which are cascaded into a two-square-meter jigger with a bed, a special iron ore cushion layer is laid on the screen surface, tailings are directly discharged to enter closed-loop beneficiation, water is directly discharged after a concentrate is separated through a three-stage desilting sand water hopper, and copper sand is directly recycled from a concentrate in a sedimentation hopper, the separation efficiency of the jigger in gravity separation is improved, and the working efficiency of the equipment process is improved.

Description

technical field [0001] The invention relates to the technical field of jigging machines, in particular to a series jigging machine system for improving the efficiency of slag sorting in domestic waste incineration. Background technique [0002] Domestic waste incineration power generation has been widely used in my country. Its advantages are: after incineration, the volume of waste can be reduced by more than 70%, which can solve the problems of high land cost of landfill and inability to meet the landfill capacity requirements. The high-temperature gas produced by waste incineration Energy can be recovered and reused. Incineration slag is a by-product of the waste incineration process, mainly including residues on the grate and particles falling from between the grate, and its output accounts for about 20%-30% of the original waste mass. Since waste is a metal substance in social life At the end point, the fine-grained slag is regarded as the raw material for beneficiation...
