Description

Hopper presses down dirt loading gate

Technical Field

And because the diameter of the chute is larger, the chute cannot well extend into the carriage, so that dust flies upwards during unloading. In addition, the chute is also required to be provided with a special fan to absorb dust and uniformly discharge the dust, which also causes certain energy consumption.

As shown in fig. 2, the form of the gate 1 and the unpowered dust suppression hopper 3 is not well matched with the large flow rate of the hopper due to the structural limitation, so that the dust suppression effect is general.

Examples

As shown in fig. 3 and 5, a hopper dust suppression loading gate comprises a gate 1, a flow pipe 4 is connected to a discharge hole of the gate (1), the flow pipe 4 is communicated with the gate 1, a split flow core 6 is connected in the flow pipe 4 through an adjusting rod 7, a flow passage 5 is arranged between the outer wall of the split flow core 6 and the inner wall of the flow pipe 4, the split flow core 6 comprises an upper split flow core 61 and a lower split flow core 62, the upper split flow core 61 is in a semicircular structure, the lower split flow core 62 is in a conical structure, the flow pipe 4 comprises an upper flow pipe and a lower flow pipe, the upper flow pipe is in a straight cylinder structure, the upper split flow core 61 is arranged in the upper flow pipe, the lower flow pipe is in a conical structure, and the lower split flow core 62 is arranged in the lower flow pipe.

According to the utility model, the adjusting rod 7 is in threaded connection with the split core 6, and the gap between the split core 6 and the discharge hole of the flow pipe is adjusted through the adjusting rod 7, so that the material flow rate is controlled.

The upper and lower split cores 61 and 62 are integrally formed in the present utility model.

The gate 1 comprises a gate fixing frame 11, a gate 12 for closing or opening a discharge hole is connected in the gate fixing frame 11, and the gate 12 is in driving connection with an oil cylinder.

The working principle of the utility model is as follows:

as shown in fig. 4, the hopper 8 forms a flow space with the loading gate 1;

let the characteristics a of the material flow over the gate be: p1-pressure; v1-flow rate; a1-cross-sectional area;

assuming that the characteristics b of the material flowing through the end of the split core are: p2-pressure; v2-flow rate; a2-cross-sectional area;

according to the bernoulli equation: p1+1/2ρv12+ρg1=p2+1/2ρv22+ρg2, wherein h1 and h2 are equal when the phenomenon of acceleration of the flow velocity and the boundary layer surface phenomenon when the fluid flows through the small cross section are combined;

as can be seen, A2 is less than A1, V2 is more than V1, and P2 is less than P1;

negative pressure is formed in the area below the area A2 where the goods flow, so that dust flying is effectively restrained.

And because the material is a naturally formed flow column, the diameter of the material is smaller, and the material can be directly filled into a vehicle without the limitation of a chute.

Meanwhile, the structure of the relative gate and the unpowered dust suppression hopper is longer, and the material flow channel is longer, so that the material does free falling motion and has V=g×t, a higher speed can be obtained, the higher speed is, the larger negative pressure formed in the A2 area is, namely the smaller P2 is, and dust flying is restrained more favorably.

In addition, the loading gate can obtain larger A1, so that negative pressure is more beneficial to generation.
