Abstract

The utility model relates to a novel dense medium shunting box for coal dressing. The novel dense medium shunting box is provided with a box type shunting box body, wherein a medium inlet pipe, a high-concentration dense medium outlet pipe, a low-concentration dense medium outlet pipe and a thin medium outlet pipe are connected with the bottom and one side of the shunting box body; a front end shunting baffle and a rear end shunting baffle are sequentially connected with the shunting box body bottom plate in the shunting box body; the front end shunting baffle is positioned between the high-concentration dense medium outlet pipe and the low-concentration dense medium outlet pipe; the rear end shunting baffle is positioned between the low-concentration dense medium outlet pipe and the thin medium outlet pipe; distances between the front end shunting baffle and the top plate of the shunting box body and between the rear end shunting baffle and the top plate of the shunting box body are reserved. The novel dense medium shunting box can change the shunt volume and the shunt concentration according to the actual demand during production, also improves the circulation and the recovery of the dense medium, improves the production efficiency, and guarantees the stability of a dense medium system.

Description

A kind of novel coal separation heavy medium shunt box

Technical field

the utility model relates to the current divider box that coal separation is used, especially a kind of novel coal separation heavy medium shunt box.

Background technology

at present, coal preparation plant carrys out coal separation with heavy medium shunt box now, but, in the casing of existing heavy medium shunt box, only has a distributing damper, and only have two dense media outlets, cause like this shunting of dense media to distribute difficult adjusting, the dense media excessive concentration of shunting or too low, has affected coal separation efficiency.

Summary of the invention

in order to solve existing current divider box shunting, distribute the problem that is difficult for adjusting, the utility model provides a kind of novel coal separation heavy medium shunt box, the novel coal separation of this one can change shunt volume and shunting concentration aborning according to actual needs with heavy medium shunt box, but also has improved circulation and the recovery of dense media.

the utility model solves the technical scheme that its technical problem adopts: the novel coal separation of this one heavy medium shunt box comprises: rear end distributing damper, front end distributing damper, current divider box main body, medium feeding pipe, high concentration dense media discharge nozzle, low concentration dense media discharge nozzle, rare medium discharge nozzle, the novel coal separation of this one is provided with a box-type current divider box main body with heavy medium shunt box, and current divider box bottom part body and a side are connected with medium feeding pipe, high concentration dense media discharge nozzle, low concentration dense media discharge nozzle and medium discharge nozzle; On current divider box main body base plate in current divider box main body, be connected with front end distributing damper and rear end distributing damper in turn; Front end distributing damper is between high concentration dense media discharge nozzle and low concentration dense media discharge nozzle; Rear end distributing damper is between low concentration dense media discharge nozzle and rare medium discharge nozzle; The top board of front end distributing damper and rear end distributing damper and current divider box main body leaves distance; During use, medium enters in current divider box main body by medium feeding pipe, and by front end distributing damper, place once shunts, and overflow is being carried out second diffluence through rear end distributing damper, so just can reach the object that changes shunt volume and shunting concentration.

the beneficial effects of the utility model, the novel coal separation of this one can change shunt volume and shunting concentration aborning according to actual needs with heavy medium shunt box, but also improved circulation and the recovery of dense media, and improved production efficiency, guaranteed the stable of dense media system.

Accompanying drawing explanation

below in conjunction with drawings and Examples, the utility model is further illustrated.

fig. 1 is cross-sectional view of the present utility model.

in Fig. 1,1. rear end distributing damper, 2. front end distributing damper, 3. current divider box main body, 4. medium feeding pipe, 5. high concentration dense media discharge nozzle, 6. low concentration dense media discharge nozzle, 7. rare medium discharge nozzle.

The specific embodiment

in Fig. 1, the novel coal separation of this one comprises with heavy medium shunt box: rear end distributing damper 1, front end distributing damper 2, current divider box main body 3, medium feeding pipe 4, high concentration dense media discharge nozzle 5, low concentration dense media discharge nozzle 6, rare medium discharge nozzle 7, the novel coal separation of this one is provided with a box-type current divider box main body 3 with heavy medium shunt box, and current divider box main body 3 bottoms and a side are connected with medium feeding pipe 4, high concentration dense media discharge nozzle 5, low concentration dense media discharge nozzle 6, rare medium discharge nozzle 7; On current divider box main body 3 base plates in current divider box main body 3, be connected with front end distributing damper 2 and rear end distributing damper 1 in turn; Front end distributing damper 2 is between high concentration dense media discharge nozzle 5 and low concentration dense media discharge nozzle 6; Rear end distributing damper 1 is between low concentration dense media discharge nozzle 6 and rare medium discharge nozzle 7; Front end distributing damper 2 and rear end distributing damper 1 leave distance with the top board of current divider box main body 3; During use, medium enters in current divider box main body 3 by medium feeding pipe 4, and by front end distributing damper, 2 places once shunt, and overflow is being carried out second diffluence through rear end distributing damper 1, so just can reach the object that changes shunt volume and shunting concentration.
