Abstract

This utility model relates to a discharging revolving bridge for plain bottom silos, which is a long structure with whose top taking the shape of a bow, and lies across on the bottom plate of the silo, with the internal end connecting to the revolving room at the center of the silo and the external end connecting with the circular rack rail by movable connection; a blocking slant plate with wider inner than the outer is fastened to the front end of the bow-shaped top plate of the revolving bridge. Radial feeding amount at different positions of the revolving bridge can be controlled by the blocking slant plate in this utility model, which insures even discharging in different positions of the silo. This utility model has the advantages of simple structure and convenience for operation.

Description

Flat bottom silo discharging reversing bridge

Technical field

The utility model relates to a kind of device for discharging of flat first in first out formula silo, particularly relates to the reversing bridge in the silo device for discharging.

Background technology

The CN1724318 patent application discloses a kind of silo that is used for storing bulking, this silo is a kind of flat first in first out formula silo, its device for discharging is arranged on one group of annular spin chamber and the annular reversing bridge on the silo base plate, wherein annular spin chamber is connected on the center shaft on the silo base plate, laterally disposed have several dischargings to put plate, and the bottom is communicated with the blanking annular groove, opens discharging pendulum plate, the above material of leaning angle can flow into the blanking annular groove by nature in the silo, arrives the outfeed belt machine.Annular reversing bridge one end is placed on the annular tooth track by drive wheel mounted thereto, and the other end is fixedly connected on the annular spin chamber, fuses with annular spin chamber, by driver drives, makes gyroscopic movement around center shaft together.The annular reversing bridge is divided into ante-chamber and back cavity by dividing plate, inboard discharging machine is installed in the ante-chamber, and by in the charging pendulum plate be communicated with silo, open and put plate in the charging, the first half branch of the following material of leaning angle is transported to the blanking annular groove and arrives the outfeed belt machine along with the revolution of annular reversing bridge enters on the inboard discharging machine in the silo; Outside discharging machine is installed in the back cavity, and is communicated with silo by charging bottom plate, open charging bottom plate, the lower part branch of the following material of leaning angle is discharged on the outfeed belt machine by outside discharging machine from level to level along with the revolution of annular reversing bridge in the silo.Above-mentioned silo has adopted leaning angle directly to be transported to the compound discharging technology of blanking annular groove discharging by the belt reversing bridge of buried type by material beyond center blanking annular groove discharging, the leaning angle with interior material, having solved the problem that the material storage of silo bottom for a long time can't discharging effectively, is a kind of discharge way of first in first out completely.

Find by practice, the annular reversing bridge structure of above-mentioned silo device for discharging also exists following weak point: because silo is circular, the inventory of its inner circumference is than outer end circumference inventory much less, if the interior outer end of reversing bridge is all with identical radially inlet amount discharging, then will certainly cause the inhomogeneous of the whole discharging of silo, inner because the fast and material bed slump of discharge rate is rapid, the outer end is owing to discharge rate forms solid accumulation slowly.For this reason, need control the radially inlet amount of reversing bridge diverse location, to guarantee the whole evenly discharging of silo by the folding degree of adjusting bottom plate on the reversing bridge.Yet, the folding degree of bottom plate on the reversing bridge accurately controlled not be one and be easy to the thing that just can accomplish.

Summary of the invention

The purpose of this utility model provide a kind of can the automatically regulating silo in the outer end reversing bridge of inlet amount radially, to realize the whole evenly discharging of silo.

Flat bottom silo discharging reversing bridge of the present utility model is the elongate structure of a top archwise, it lies across on the silo base plate, the inner is connected on the spin chamber at silo center, annular tooth track on outer end and the silo wall flexibly connects, surround a cavity between the arc top board of reversing bridge and the base plate, the cavity front end is communicated with silo, it is characterized in that the front end at the arc top board of reversing bridge is fixedly connected with the backgauge swash plate of an inner wide and outer narrow.

According to the difference of silo internal diameter size, and, can do suitable adjustment to the leaning angle of backgauge swash plate, generally between 1～30 ° to the different demands of load size.

The radially inlet amount at the backgauge swash plate control reversing bridge diverse location place of the utility model by being fixed on reversing bridge arch roof front edge of board has advantage simple in structure, easy to operate.Because the inner swash plate broad of backgauge swash plate, the inventory that enters in the reversing bridge is less relatively; The outer end swash plate is narrower, and the inventory that enters in the reversing bridge is more relatively, has therefore guaranteed the evenly discharging of material at diverse location place in the silo.

Description of drawings

Fig. 1 is the structural representation of the utility model flat bottom silo discharging with reversing bridge;

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

As shown in Figure 1, flat bottom silo discharging reversing bridge is an elongate structure, and its inner is connected on the spin chamber 1 that is positioned at the silo center, and the annular tooth track 3 on outer end and the silo wall 2 flexibly connects, thereby lies across on silo base plate 6.Front end at reversing bridge is fixedly connected with a backgauge swash plate 5, the inner broad of backgauge swash plate 5, and the outer end is narrower.

The flat bottom silo discharging with the inner structure of reversing bridge as shown in Figure 2, the top of reversing bridge is an arc top board 4, surrounds a cavity between itself and the base plate 7.Discharging machine 8 is installed in the cavity, and the front end of cavity is communicated with silo, and material can enter and be discharged in the cavity on the discharging machine 8.Front end at the arc top board 4 of reversing bridge is fixedly connected with a backgauge swash plate 5, along with the variation of backgauge swash plate 5 width, regulates the inventory that enters cavity, controls the load size of different radial positions.

Claims (2)

1, a kind of flat bottom silo discharging reversing bridge, be that a top is arc elongate structure, lie across on silo base plate (6), the inner is connected on the spin chamber (1) at silo center, annular tooth track (3) on outer end and the silo wall (2) flexibly connects, surround a cavity between the arc top board (4) of reversing bridge and the base plate (7), the cavity front end is communicated with silo, it is characterized in that the front end at the arc top board of reversing bridge (4) is fixedly connected with the backgauge swash plate (5) of an inner wide and outer narrow.

2, flat bottom silo discharging reversing bridge according to claim 1, the leaning angle that it is characterized in that described backgauge swash plate (5) is 1～30 °.
