The technical field is as follows:

the utility model relates to a coal gangue separator especially relates to a horizontal medium stream feed arrangement for heavy-duty medium shallow slot sorting machine.

Background art:

the heavy-medium shallow slot is formed by layering materials in a heavy-medium suspension according to different densities, heavy products with the density larger than that of the suspension are deposited at the lower part of the shallow slot, light products with the density smaller than that of the suspension are discharged together with the heavy-medium suspension through a discharge hole at the front end of the shallow slot, the sorting equipment is used for both a horizontal medium flow and an ascending medium flow, the horizontal medium flow continuously replenishes qualified suspension for the sorting slot, the density reduction of the sorting slot is prevented, the ascending medium flow causes a weak ascending speed, the suspension is prevented from being deposited in the sorting slot, the density of the suspension in the sorting slot is kept stable by the horizontal medium flow and the ascending medium flow, and the; in the prior art, a horizontal medium flow enters a separation groove from the side surface along the full width of a feeding port of a heavy-medium shallow groove separator uniformly, the medium flow density on the upper part of the groove body is stable, and Chinese patent No. 201620144117.1 discloses a horizontal medium flow feeding device of a large-scale heavy-medium shallow groove separator, which comprises two flow dividing pipes, a mixing pipe and a dispersion plate and has the main function of enabling the horizontal medium flow to consume kinetic energy and be uniformly distributed; however, the combination of the shunt pipes and the dispersion plate are greatly washed by water flow, and are easily damaged by abrasion, and in addition, the arrangement of the inclined dispersion grooves can ensure the natural outflow of the horizontal medium flow, but certain potential energy is increased, so that the stable horizontal medium flow generates certain fluctuation, the separation of the heavy medium shallow grooves is not facilitated, and the separation efficiency is reduced.

The utility model has the following contents:

an object of the utility model is to provide a horizontal medium stream feed arrangement for heavy-duty medium shallow slot sorting machine.

The content of the utility model is as follows: a horizontal medium flow feeding device for a heavy medium shallow slot separator comprises a feeding main pipe which is vertically arranged, a flange cover is hermetically connected with the top end of the feeding main pipe through a bolt, the two sides of the feeding main pipe are symmetrically communicated with material distributing pipes, the top ends of the material distributing pipes are horizontally provided with material distributing pipes, the material distributing pipes are positioned right above the feeding main pipe, a plurality of feeding pipes are vertically and upwards communicated with the top end of the distributing pipe, the feeding pipes are communicated with the material stabilizing groove, the material stabilizing groove comprises an inclined groove section and a horizontal groove section, the bottom of the groove wall of the horizontal groove section is uniformly provided with discharging through holes, the bottom end of the flange cover is fixedly connected with a wear-resistant column, the bottom end of the wear-resistant column is hemispherical, the wear-resistant columns are inserted into the feeding main pipe, and the feeding main pipe is in clearance fit with the wear-resistant columns; the cloth tube is internally and fixedly provided with a material stabilizer, the cross section of the material stabilizer is in an isosceles triangle shape, the vertex of the material stabilizer faces downwards vertically, the two waist vertexes of the material stabilizer are fixedly connected with the inner wall of the cloth tube, a plurality of flow stabilizing through holes are uniformly distributed on the two waist of the material stabilizer, floating pieces are arranged in the horizontal groove section and float on the water surface of the material stabilizer.

The utility model has the advantages that: the utility model has simple structure, the dispersion plate is designed into a triangular prism shape, which not only effectively plays the role of shunting and reducing kinetic energy, but also is wear-resistant and not easy to damage; the wear-resistant column is designed at the joint of the shunt tubes, so that the scouring of water flow can be effectively resisted; the floating pieces are designed at the horizontal groove section of the material stabilizing groove, so that the fluctuation of horizontal medium flow is prevented, the separation of the heavy medium shallow grooves is facilitated, and the separation efficiency is improved.

Description of the drawings:

fig. 1 is a solid diagram of the overall structure of the present invention;
