In order to achieve the above object, the utility model is achieved in that:

A lift-type steel ore bin, including a bracket, a bin body, a funnel, and vibrating feeding and conveying equipment, wherein the funnel is arranged below the outlet at the bottom of the bin body, and the vibrating feeding and conveying equipment is arranged at the bottom of the outlet at the bottom of the funnel Below, the bracket includes an upper bracket, a lower bracket and a funnel bracket. The upper bracket is socketed with the lower bracket and the upper bracket can rise or fall along the lower bracket. The mine bin body is fixed in the center of the upper bracket, and the lower bracket is provided with a funnel bracket, and the funnel overlaps with the mine bin body and is arranged in the funnel bracket.

In the lift-type steel ore bin, the upper bracket and the lower bracket both include four columns and beams for enclosing the four columns to form a rectangular frame structure, and the four columns of the upper bracket are socketed on the four columns of the lower bracket. .

In the lift-type steel ore bin, the joint between the funnel and the bin body is threaded through connecting bolts.

Benxi Iron and Steel’s ore warehouse adopts the above-mentioned design, and realizes the overall modularization of the steel ore warehouse that is traditionally fabricated and installed on site through liftable brackets, so as to achieve the purpose of lowering the center of gravity of the steel ore warehouse itself, reducing its volume, and facilitating transportation and reinstallation. It brings convenience to the installation of steel ore bins.

detailed description

Below further illustrate the utility model by specific embodiment.

As shown in Figure 1 and Figure 2, a lift-type steel ore bin includes a bracket 4, a bin body 1, a funnel 2 and a vibrating feeding conveying device 5, wherein the funnel 2 is located at the bottom outlet of the bin body 1 Below, the vibrating feeding conveying equipment 5 is located below the discharge port at the bottom of the funnel 2, the support 4 includes an upper support 6, a lower support 7 and a funnel support 3, the upper support 6 is socketed with the lower support 7 and the upper support can be moved along the lower support As shown in Figure 3, the upper bracket 6 and the lower bracket 7 are fixed by the pin connection of the bolt 8 and the threaded connection of the bolt 9, the mine bin body 1 is fixed on the center of the upper bracket 6, and the lower bracket 7 is provided with The funnel support 3 and the funnel 2 overlap the mine bin body 1 and are arranged in the funnel support 3 .

In the lift-type steel ore bin, the upper bracket 6 and the lower bracket 7 both include four columns and a crossbeam for enclosing the four columns to form a rectangular frame structure, and the four columns of the upper bracket 6 are sleeved on the lower bracket 7. on four pillars.

In the lift-type steel ore bin, the joint between the funnel 2 and the bin body 1 is threaded through connecting bolts.

The disassembly method of the lift-type steel ore bin includes the following steps;

Step 1. According to the design drawings, use steel profiles to make brackets, mine bin bodies, and funnels, and prepare vibration feeding and conveying equipment;

Step 2, pre-assembly;

Pre-assemble in the order of the lower bracket, vibrating feeding conveying equipment, funnel bracket, funnel, upper bracket, and mine bin body;
