How the meter works

The air valve sends air into and out of the air chamber of the jig at a selected frequency so that the water medium in the jig forms a pulsation motion up and down. The raw coal fed into the first section (gangue section) of the machine body from the infeed section is layered on the sieve plate by density under the action of pulsating water flow. The denser vermiculite gradually sinks. The material moves forward during the pulsation and the vermiculite is discharged through the gate at the end of the meteorite section to the discharge. The clean coal and Chinese coal continue to be stratified with the pulsation water flowing into the second section (middle coal section). At this time, the medium coal is distributed in the bottom layer, moves to the end of the coal gate through the gate and discharges to the middle coal layer, and the top coal is distributed from the top layer. The overflow at the discharge end of the machine body allows the raw coal to be divided into three products: vermiculite, medium coal and clean coal.

IV. Structure Introduction In order to meet the needs of the production process layout, the jig design has two forms, left and right. Looking at the direction of coal flow, the air valve is left-handed on the left, and vice versa.

The machine consists of a body, a rotary air valve system, a bucket elevator system, and a discharge device.

(A) The body is a metal structural member welded with steel plates of 8mm-10mm thickness. Each of the divided rock sections and the middle coal sections is divided into two jigs by compartments. The screen body is provided in the body for layering the material on it.

(2) Air valve system The local air valve is a new rotary air valve, which has the advantages of small size, light weight, large inlet area, simple structure, convenient installation and maintenance, etc. Its structure is mainly composed of a shell and a rotor, and is eliminated. The adjustment sleeve of the rotary damper is generally fixed to fix the damper curve at an optimum value. The rotor is a hollow cylinder with ribs in the middle. The surface is opened with a rectangular exhaust hole with a rotor angle of 60°, and the rotor is fixed on On the rotor shaft, the rotor shaft supports the shaft sleeves at the left and right ends, and is fixed to the housing through the end cover. The clearance between the rotor and the housing is sealed and the characteristic curve of the air valve is provided.

(III) Bucket elevator system The sulfur analyzer consists of a hoist head, a head drive system head frame, a bucket chain, and a tail device. The two hoists of the machine have their own independent transmission system, and the lower device will have a sieve hole. Leakage is sent to the end of each segment.
