A dust-free coal screening device

Abstract

The invention discloses a dustless coal screening device. The dustless coal screening device comprises an outer shell, a feed port integrally formed in one side of the upper surface of the outer shell, and a discharge port integrally formed in the surface of the other side of the outer shell opposite to the feed port; rings are arranged at the lower end of the discharge port; a collecting bag is fixed on the rings through a fixing module; the two rings are connected through a fixed plate; a thread hole is formed in middle of the fixed plate; and a thread column is screwed in the thread hole. The rings are arranged under the discharge port; the collecting bag sleeves the rings; clamping rings are arranged at the upper ends of the rings; the lower ends of the clamping rings are connected with clamping plates through springs; one ends of the clamping rings are connected with extension rods; after the collecting bag sleeves the rings, and when the clamping rings are descended to proper positions through the extension rods, bolts are inserted into insertion holes; and through the effects of the springs and the clamping plates, an opening of the collecting bag is fixed to achieve installation.

Description

technical field [0001] The invention belongs to the technical field of coal screening, in particular to a dust-free coal screening device. Background technique [0002] When the existing coal screening device collects the coal that has been screened, most of them use collection bag coal to collect. However, when collecting, the coal is easy to leak from the collection bag because the collection bag is not fixed properly. [0003] Also, when collecting, when the collection bag is full, the equipment will generally not stop. At this time, the collection bag needs to be replaced, and it will take a long time. During this time, coal will fall to the ground in large quantities, and people need to go there afterwards. It is very troublesome to pick it up. Contents of the invention [0004] In order to solve the problems raised in the above-mentioned background technology. The invention provides a dust-free coal screening device, which has the characteristics of more secure fix...

Problems solved by technology

[0002] The existing coal screening device, when collecting the screened coal, mostly uses coal collection bags for collection. However, when collecting, the coal is easy to leak from the collection bag because the collection bag is not fixed securely.

[0003] Also, when collecting, when the collection bag is full, the equipment will generally not stop. At this time, the collection bag needs to be replaced, and it will take a long time. During this time, coal will fall to the ground in large quantities, and people need to go there afterwards. Pick it up, very troublesome
