Drawings
Fig. 1 is a schematic diagram of the present invention.
Detailed Description
For the purpose of illustrating the spirit and purposes of the present invention, the present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a spraying device for coal fire retardant in coal conveying process, which is used for spraying fire retardant on coal on the surface of a conveying belt, comprises a fire retardant mixing box 1, a dosing machine 2 provided with a medicine box 21 inside, a water pump 3 and a spraying assembly 4, wherein the spraying assembly 4 at least comprises a plurality of shunt tubes 41 and a plurality of spraying heads 42 arranged on the shunt tubes 41 and communicated with the shunt tubes 41; the liquid inlet of fire retardant mixing box 1 is connected with inlet tube 11, and the medicine outlet of dosing machine 2 is connected with the medicine inlet of fire retardant mixing box 1, and the one end of water pump 3 is connected with the liquid outlet of fire retardant mixing box 1, and the other end is connected with shunt tubes 41, and shunt tubes 41 set up perpendicularly directly over the coal conveyer belt and perpendicular with the direction of delivery that the coal was carried, and the fire retardant in fire retardant mixing box 1 spouts the coal on the conveyer belt through water pump 3, shunt tubes 41 and sprinkler head 42.
As shown in figure 1, a chemical adding machine 2 adds chemical liquid into a flame retardant mixing box 1, a water inlet pipe 11 conveys tap water or industrial water into the flame retardant mixing box 1, and the chemical liquid is mixed with the tap water or the industrial water to form the flame retardant. Coal is transported on the upper surface of the conveying belt, and in the transporting process, the spraying heads 42 spray the fire retardant to the coal on the surface of the conveying belt, so that the transported coal is fully sprayed with the fire retardant, spontaneous combustion of the coal in a storage yard is prevented, and dust is generated in the transporting and stacking process; the labor intensity can be reduced, and the coal fire retardant can be uniformly sprayed.
