Existing material bin structure, between the bulkhead of cone hopper and liner plate, be generally bolted, in actual production process, need on bulkhead, bore a large amount of holes, because cone position, hopper inner space is narrow and small, the position, cone bottom that is particularly to bore hopper, space is extremely narrow, therefore, in the time of boring, difficulty of construction is large, holes consuming time of a specified duration.Meanwhile, due to bolts, so necessarily have bolt cap and give prominence on liner plate, outstanding bolt cap can hinder the discharging of material, and material is easily piled up in the outstanding position of bolt cap simultaneously, causes the obstruction of material, affects discharging.
In the present embodiment, round steel bar 7 can be welded and fixed with an end face of described liner plate 2 and the inner barn wall 4 of described cone hopper 1 respectively.So, can ensure that the other end of the liner plate 2 after fixing is smooth, reduce material and the friction force of boring between hopper 1 in discharge process, play and helped stream effect, prevent the obstruction of material bin.Preferably, described liner plate 2 is smooth high molecular abrasion-proof liner plates, as, polyfluortetraethylene plate.Wherein, the quantity of described round steel bar 7 can arrange according to the laying condition of liner plate 2 in actual production process.
Preferably, with reference to Fig. 2, be a kind of liner plate laying structure schematic diagram of material bin shown in Fig. 1.In the present embodiment, described liner plate 2 comprises at least one sub-liner plate 13.In the actual process of deployment of liner plate 2:
First, measure inner barn wall 4 sizes of described cone hopper 2, according to the size of inner barn wall 4, inner barn wall 4 is carried out to separated time layout.
Secondly, according to the geomery of described inner barn wall 4 and described separated time layout, liner plate 2 is cut and obtains at least one sub-liner plate 13.
Then, described at least one sub-liner plate 13 connect by polyolefin is gluing between any two, obtain the described liner plate 2 identical with interior bulkhead 4 geomeries of described cone hopper 2.It should be noted that, sub-liner plate can but be not limited only to connect by polyolefin is gluing.
Finally, described round steel bar 7 one sides are weldingly fixed on to the junction between two (, separated time place) of described at least one sub-liner plate 13, described round steel bar 7 opposite sides are weldingly fixed on the interior bulkhead 4 of described cone hopper 2.So that described round steel bar 7 is as the shielding wire between liner plate 2 and interior bulkhead 4, play the effect of dilatation joint simultaneously.Wherein, described round steel bar 7 can be that diameter is the cylindrical steel rods of 4mm, and the length of described round steel bar 7 is identical with the connection lead length of the junction between two of described at least one sub-liner plate.Described sub-liner plate 13 can be that thickness is the polytetrafluoroethylene liner plate of 5mm.
Described at least one air bubble 5 is distributed on the outer bulkhead of described cone hopper by setting intervals.
In the present embodiment, the quantity of air bubble 5 can arrange according to needs of production, and the present embodiment is not restricted this.Preferably, in actual production process, described at least one air bubble 5 can be arranged on to the often susceptible to plugging position of appearance of cone hopper 1 by setting intervals.As, described air bubble 5 can be arranged to outer bulkhead 3 middle parts of described cone hopper 2, that is, described air bubble 5 is identical with the vertical distance that described air bubble 5 arrives described cone hopper 2 discharging openings to the vertical distance of described cone hopper 2 inlet points.Wherein, preferably, be also provided with a star-shaped discharge valve 14 in the position of described cone hopper 2 discharging openings.
The principle of work of described air bubble 5 is as follows: in discharge process, start air bubble 5, the pressure gas that air bubble 5 sprays enters in described cone hopper 2, material in described cone hopper 2 is purged, reach the effect of broken arch, block clearing, make Flow of Goods and Materials normal, avoided the obstruction of material bin.Here it should be noted that, described air bubble 5 can be always in opening in discharge process; Also can in discharge process, there is arch material in described air bubble 5, stop up or storehouse at the bottom of discharging start when smooth, in the time that Flow of Goods and Materials is normal, close, to save power consumption, avoid the wasting of resources.
In the present embodiment, described air bubble 5 comprises: fixed support 10, air bubble main body 9 and freeing pipe 11.
One end of described fixed support 10 is connected with described air bubble main body 9, and the other end of described fixed support 10 is connected with the outer bulkhead 3 of described cone hopper 1, so that described air bubble 5 is fixed on the outer bulkhead 3 of described cone hopper 1.
