Detailed Description
So that those skilled in the art can better understand the technical solution of the present invention, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in figures 1 to 4, the embodiment of the utility model discloses a washable anti-sticking and anti-blocking coal slime chute device, including cell body 1, plenum 2 and geomantic omen 3, cell body 1 comprises bottom plate 11 and inverted U-shaped casing 12 cavity, and bottom plate 11 is equipped with a plurality of through-holes 13 along width direction, and through-hole 13 becomes the acute angle with the face of bottom plate 11. The wind chamber 2 is arranged at the bottom of the tank body 1. The wind chamber 2 is bolted with the inverted U-shaped housing 12 and the base plate 11. The two ends of the air-water main pipes 3 are used for respectively introducing water and air, and the two air-water main pipes 3 are respectively arranged at the two sides of the groove body 1 and are communicated with the air chamber 2 through the air-water branch pipes 4. The cross section of the main air-water pipe 3 is rectangular, so that the air-water branch pipes 4 can be conveniently installed. The two ends of the air-water main pipe 3 are provided with connecting ends with flange openings so as to be respectively connected with an air pipe and a water pipe to be introduced with air or water.
In this embodiment, the bottom plate 11 is made of ultra-high molecular weight polyethylene. The included angle between the through hole 13 of the bottom plate 11 and the plate surface of the bottom plate 11 is 30 degrees. The diameter of the through hole 13 is 2 mm-3 mm.
In this embodiment, a plurality of air grooves 21 are uniformly distributed in the air chamber 2, an air-water branch pipe 4 is arranged in each air groove 21, the air-water branch pipe 4 is L-shaped, the air-water branch pipe 4 is connected with an air-water header pipe 3, and an umbrella-shaped shielding plate 5 is arranged at the top of each air-water branch pipe 4. The umbrella-shaped shielding plate 5 can prevent the material from blocking the air-water branch pipe 4 and disperse the blown air flow.
In this embodiment, two vibration motors 6 are provided on the top of the inverted U-shaped housing 12. The top of the inverted U-shaped shell 12 is provided with two channel steels 7 side by side along the length direction, and the vibration motor 6 is arranged on the channel steels 7. The main effect of vibrating motor 6 is for providing the exciting force of perpendicular to chute plane for whole chute, strengthens the desorption effect of coal slime, and the main effect of two channel-section steels 7 is the structural strength who strengthens the shell 12 that falls U-shaped to lead to the chute fracture under long-time vibration stress concentration effect.
