Abstract

The utility model relates to a machine for coal sorting, which is composed of a transmission system, a piston group, a jigging slot body and a reject discharge and cinder storing device. The utility model is characterized in that the transmission system is installed above the jigging slot, and the other side of the jigging slot is provided with the reject discharge and cinder storing device; thus, the continuously automatic reject discharge can be realized. The utility model has the advantages of simple structure, convenient installation and use, small ground occupation, high efficiency of coal sorting, and high quality. In addition, the utility model can save the capital expenditure and reduce the coal sorting cost greatly.

Description

Plunger jig for coal sorting

The utility model relates to a kind of coal separation machinery that uses water as medium, also can be used for the sorting of other mineral.

Existing piston jig, its structure generally is that transmission system and the split of jigging groove are laid on the ground, and the discharge refuse form is to release at the bottom of the manual discontinuous slit, and the jigging bottom land need have been built the bastard coal storehouse.High about 3 meters of bastard coal storehouse.Heavily about 3 tons of complete equipment, per hour handling capacity is 12～18 tons.This device structure is complicated, and consumption material is many, and occupation of land is many with capital expenditure, operation inconvenience, and the coal separation cost is higher.

The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of lateral flow type continuous discharge refuse jigging machine, reduces capital expenditure and coal washing cost.

Technical scheme is that by motor, the transmission system that reduction box, eccentric wheel, power transmission shaft, connecting rod are formed is installed on the top of jigging groove side piston chamber, piston chamber and jigging groove composition one; Jigging groove opposite side bottom offers mud hole, and mud hole is provided with storage slag case outward, and the discharge refuse form is the continuous discharge refuse of automatic lateral flow type, and storage slag case and jigging groove are linked to be an integral body.There is slag trap at the mud hole place, in the storage slag case discharge refuse valve is arranged, and all controls by handle.Wear-resistant rubber sheet is arranged around the piston plate, and available bolt is regulated.The eccentric wheel shell is two semicircles, and shell is concavo-convex the cooperation with eccentric wheel periphery interface, eccentric wheel outer casing underpart and rod hinge connection.

The utility model is compared with traditional jigging machine, has following superiority: 1. transmission system, sorting groove, waste stone exhaust system are linked as an integral body, compact conformation, and installation and maintenance are convenient.2. complete machine is heavily about 2,0 tons, about 1 ton of material saving.3. change the interrupted manually discharge refuse of upright releasing type and be the continuously automatic discharge refuse of lateral flow type, easy to operate.4. this utility model need not built discharge refuse storehouse and reinforced concrete pedestal, saves capital expenditure and coal separation cost.5. handling capacity per hour can reach 18～25 tons, coal separation efficient height.

Accompanying drawing provides an embodiment of the present utility model.

Fig. 1 is a groove side discharge refuse piston jig structural representation.

Fig. 2 is the side-looking generalized section of Fig. 1.

Fig. 3 is eccentric wheel and connecting rod connection diagram.

Shown in Figure 2 according to Fig. 1, transmission system is made up of motor 5, reduction box 6, power transmission shaft 10, eccentric wheel 8, connecting rod 16.6 eccentric wheels are positioned on the

power transmission shaft

10, and 3 cover shaft coupling 7 and 6 bearing blocks 9 are arranged on the power transmission shaft, and transmission system is fixed in the piston chamber 17 of jigging groove 1 side by the support of bearing 4.Connecting rod 16 upper ends connect eccentric wheel, and its lower end connects piston plate 2 by bearing pin, around the piston plate adjustable wear-resistant rubber sheet are housed, and can regulate by bolt.Piston is done in piston chamber and is pumped.The piston chamber bottom is communicated with the jigging groove, and the jigging groove has three Room, divides triple jump to eliminate.The groove bottom is provided with permeable sieve plate 11.Water inlet pipe 15 connects piston chamber, can enter in the jigging groove by permeable sieve plate after water enters.Jigging groove two ends are respectively equipped with charging, discharging opening.Jigging groove opposite side bottom has 3 mud hole 19a, and mud hole is provided with storage slag case 18 outward, and mud hole 19b is arranged at the bottom of the case, in the storage slag case discharge refuse valve 13 is arranged, and the discharge refuse valve is by handle 12 controls, and the mud hole place is provided with slag trap 3, and slag trap connects handle 14.

According to shown in Figure 3, eccentric wheel 8 is hinged by eccentric wheel shell 21 and connecting rod 16, and the eccentric wheel shell is two semicircular shaped object, and upper and lower two sides of shell are respectively protruded one, and has screw with bolt 20 fastening alignment pins 23 in addition, and shell is fastened on the eccentric wheel 8.Shell is concavo-convex the cooperation with eccentric wheel periphery interface, saves the binding on the eccentric wheel section.Also be provided with grease cup 22 on the eccentric wheel shell 21.

Operation principle is, coal or ore pour the jigging groove by water, and along with the reciprocating motion of piston, WATER AS FLOW MEDIUM also back and forth flows, and material (raw coal) is carried out gravitational separation, and light material cleaned coal floats over the top of water, is washed away by top water, flows into the cleaned coal pond.Weight spoil and assorted material then sort out from the leading portion of jigging groove, discharge automatically from groove side mud hole, thereby along with continuous separation of constantly carrying out realizing weight (spoil, impurity) and unsteady thing (cleaned coal) of sorting.
