Description

Anti-blocking device for silo discharge

technical field

The utility model relates to the technical field of material storage equipment, in particular to an anti-blocking device for discharging material from a silo.

Background technique

At present, metallurgy, thermal power generation and mines are developing toward large-scale, the size of raw material bins is increasing, and the phenomenon of blockage of material bins is becoming more and more serious. Traditional silo declogging methods include installing air cannons and installing vibrating mechanisms on the outer wall of the silo, etc. This method of declogging cannot effectively solve the silo blockage fundamentally.

Utility model content

The purpose of the utility model is to provide a material bin discharge anti-blocking device which can fundamentally and effectively solve the blockage of the bin.

For achieving the above object, the technical scheme that the utility model adopts is:

The anti-blocking device for silo discharge includes a distributor connected to the outlet of the silo. The distributor includes a shell with upper and lower openings. The shell is fixedly connected with a material distribution mechanism. The material distribution mechanism is an upright conical structure. ; The lower part of the feeder is provided with a spiral discharge mechanism, and the bottom of the spiral discharge mechanism is provided with a discharge port.

The screw discharge mechanism includes an auger, which is connected to the power device through a rotating shaft; the auger is divided into a left auger and a right auger with the same structure and opposite directions of rotation, and the left auger and the right auger are distributed on both sides of the rotating shaft. At the end, there is a discharge port under the middle part of the rotating shaft.

The material distributing mechanism is fixed in the middle of the distributor by two angle steels facing upward at right angles, and the two angle steels are perpendicular to each other.

The vertical section of the feeder is an inverted trapezoid, the feeder is located at the middle and lower part of the feeder, the boundary between the left auger and the right auger is located under the feeder, and the discharge port is located under the feeder.

The interior of the conical material distributing mechanism is hollow.

In the utility model, a feeder is provided at the outlet of the silo, and the feeder mechanism in the feeder can distribute the material to the side of the feeder, preventing the material from falling directly at high speed and causing blockage; the feeder structure adopts an upright position The conical structure facilitates the falling of materials and prevents material accumulation and blockage; the screw discharge mechanism under the distributor adopts the left and right augers with the same structure and opposite rotation direction to push against each other, and the material distribution mechanism is distributed to the side of the distributor. The counter-push in the middle enables the material to be discharged from the discharge port below the middle of the rotating shaft to realize forced discharge, so as to ensure the smooth discharge of the material and prevent blockage; The angle steel on the top is fixed to prevent the fixed part from collecting materials, and further prevent the material from clogging. The two angle steels are vertically arranged and fixed firmly; Basically effectively solve the problem of silo blockage.

Detailed ways

As shown in Figure 1, Figure 2, and Figure 3, the anti-blocking device for silo discharge includes a feeder 1 connected to the outlet of the silo, and the feeder 1 includes a shell with upper and lower openings, and the shell is fixedly connected with The material distribution mechanism 2 is an upright conical structure 21; the lower part of the material distributor 1 is provided with a screw discharge mechanism 3, and the bottom of the screw discharge mechanism 3 is provided with a discharge port 33. The screw discharge mechanism 3 includes an auger, the auger is connected to the power unit motor 5 through a rotating shaft 34, and the motor 5 is connected to the outside of the screw discharge mechanism 3 through a fixed seat 4; Left auger 31 and right auger 32, left auger 31 and right auger 32 are distributed in the two ends of rotating shaft 34, are provided with discharge opening 33 below the middle part of rotating shaft 34. The material distribution mechanism 2 is fixed in the middle of the material distributor 1 by two angle steels 22 and 23 facing upward at right angles, and the two angle steels 22 and 23 are perpendicular to each other and arranged up and down along the material distribution mechanism 2 . The vertical section of the distributor is in an inverted trapezoidal shape (as shown in the upper part of Figure 2), the material distribution mechanism 2 is located at the middle and lower part of the material distributor 1, and the boundary between the left auger 31 and the right auger 32 is located below the material distribution mechanism 2, The discharge port 33 is located below the material distributing mechanism 2 . The interior of the conical material distributing mechanism is hollow.

When the utility model is working, the material enters the material distributor 1 through the hopper, and under the action of gravity, the material falls to the surroundings of the material distributor 1 along the outer edge of the material distribution mechanism 2 in the material distributor 1, so as to prevent the material from distributing too quickly. The bottom of the feeder 1 is piled up, and the bottom of the feeder 1 is provided with a left auger 31 and a right auger 32 with the same structure and opposite rotation to push the material, and push the material to the middle of the screw discharge mechanism so that the material is discharged from the discharge port 33 Discharge, realize forced discharge, can effectively avoid material blockage, and the use effect is good.
