Embodiment Construction

[0027] An intermittent foam dust-reducing sprinkler head for underground coal mine construction in the present invention is realized in this way. When in use, when carrying out dust-reducing during underground construction, first install and fix the present invention on the external dust-reducing device through three fixing ears (2), and then install it on the main body Add a certain amount of water and foaming agent into the barrel (1), drive the motor (7) to work, and the motor shaft drives multiple foam plates (9) and spiral stirring blades (4) to rotate, and drives them through the connecting ring (11) The rotating rod (12) rotates, the connecting ring (11) drives the filter screen (5) to rotate through a plurality of arc-shaped rods (20), and the plurality of foam plates (9) and the spiral stirrer (4) respectively rotate to the main cylinder ( 1) Stir the foaming agent and water inside to make it generate foam. At the same time, the spiral stirrer (4) drives the foam to mo...

Abstract

The invention relates to an underground intermittent foam dust-falling spraying nozzle for coal mine construction, and discloses a spraying nozzle which can spray foam intermittently to make the foambe in full contact with dust for improving dust-falling effect. The underground intermittent foam dust-falling spraying nozzle is characterized in that three fixed lugs are arranged on the outer sideof a main body cylinder at equal intervals, and fixed holes are formed in each fixed lug; a plurality of spraying slots are formed in the bottom of the main body cylinder at equal angles, and each spraying groove is of an elliptical structure; each spraying slots is internally provided with a split net, each split net is made of steel wires, the surface of each split net is coated with a coating layer, and spraying rings are placed in the spraying grooves and connected with the main body cylinder through two connecting plates, and a supporting ring is arranged in the main body cylinder and connected with the inner wall of the main body cylinder through a plurality of fixing rods; and a driving motor is placed in the inner ring of the support ring, one end of a rotating rod is connected with one end of a motor shaft of the driving motor through a connecting ring, a fixed table is arranged at the other end of the rotating rod through a bearing and connected with the middle of the bottomend of the main body cylinder, and the fixed table is in a round table shape.

Description

technical field [0001] The invention relates to an intermittent foam dust-reducing nozzle for coal mine construction underground, which relates to a nozzle for reducing dust by intermittently spraying foam and belongs to the field of coal mine equipment. In particular, it relates to a spray head which can fully contact the foam and dust through intermittent foam spraying and improve the effect of dust suppression. Background technique [0002] At present, in the process of coal mining, the hazard of dust is one of the most important occupational hazards. In order to prevent and control underground dust, the method of dust suppression will be used to reduce dust during mining operations, but this method cannot effectively carry out continuous dust reduction. The more advanced foam dust reduction technology is developed. The foam is sprayed on the underground working surface to absorb the dust. Due to the large surface area of ​​the foam, the dust adsorption efficiency is high...
