Abstract

The utility model provides a charging device of a preheating device pipe in a lime calcining system. The utility model is characterized in that the upper end of a vertical device in the utility model is connected with a charging groove, and the lower end of the vertical device is connected with a lower box body in which a valve control mechanism composed of a guide rail and a trolley is arranged. The lower end face of a steel pipe is made into an oblique angle of 5 DEG, and the distance between the lower end face of the steel pipe and the trolley is 30 mm. The bottom surface of the lower box body is provided with an opening communicated with a preheating device. The utility model has the advantages of simple structure, light weight, no power consumption and simple and convenient operation and alters a complicated structure composed of a plurality of vibrating motors and a plurality of mechanical control mechanisms in the prior art.

Description

Preheater pipeline feeding device in the lime calcining system

The utility model relates to a kind of by inject the vertical pipeline feeding device of Wingdale in device, especially the lime calcining system of vertical pipeline injecting material in preheater.

At present in the prior art, Anshan Iron and Steel Company's first phase of construction has been introduced the vibration material feeding that injects Wingdale in the lime calcining system that German Claus Mafi company provides in preheater.Its mode of operation is: Wingdale enters the vibration charging chamber through the top charging tank, and the vibration charging chamber is for being symmetrically arranged, a cover job, and a cover is standby.Indoor at vibration charging, Wingdale is through the top feeder, and shutter door mechanism enters upper box, continues to fall into to a 2m again ³In the hopper, and then through the bottom feeder, shutter door mechanism enters lower box.Wingdale has just been finished the stroke in the vibration charging chamber like this, enters intermediate chute at last, in tremie pipe enters preheater.Vibration material feeding of the prior art, complex structure promptly has 4 mechanical handling mechanisms, 4 vibrating motors.Equipment very easily breaks down and vibration charging is finished on more than 20 meters platforms in long-term vibration work, and maintenance is extremely inconvenient, and current consumption is big, cost height, ton surplus whole installation weight reaches 10.

The purpose of this utility model is to change the weak point that prior art exists, and a kind of preheater pipeline feeding device of only using two direct blankings of vertical pipeline is provided.

The purpose of this utility model can be achieved through the following technical solutions: in the pipeline feeding device that is made of steel pipe, charging tank, lower box, gate controlling organization, connect charging tank in the upper end of steel pipe, connect lower box, in lower box, be provided with the gate controlling organization in the bottom of steel pipe.

The purpose of this utility model can further be achieved through the following technical solutions: the gate controlling organization is arranged in the lower box, is to be made of guide rail that is arranged on the lower box bottom surface and dolly.Steel pipe is provided with 2 at least, and its underpart should be inserted in the lower box, and should there be 5 ° oblique angle its lower surface, also requires at least 25 mm distance between the dolly of its lower surface and gate controlling organization.

The advantage that the utility model compared with prior art has is: (1) is simple in structure, only uses two direct blankings of vertical pipeline.(2) in light weight, saved many vibrating motors and a plurality of mechanical handling mechanism.(3) no power consumption is easy to maintenance, and is easy and simple to handle.

The utility model provides the following drawings: accompanying drawing 1 is the utility model structural representation.Accompanying drawing 2 is a gate controlling organization synoptic diagram.

Be described in further detail below in conjunction with drawings and Examples:

As shown in drawings, in the utility model, 2 vertical steel pipes (2) are set, diameter is at least 400 millimeters of Φ, and length is at least 4000 millimeters.In the upper end of steel pipe (2) 1 charging tank (1) is set, connect by flange between them, in the bottom of steel pipe (2) 1 lower box (3) is set, steel pipe (2) should insert in the lower box (3), connect between them and should seal tightly, and require to do 1.5 normal atmosphere leak detections, prevent in working order, because of contrary air-flow appears in gas leakage, influence is reinforced.Lower surface at steel pipe (2) is a discharge port, 5 ° of oblique angles that should be made into.Be provided with gate controlling organization (4) in lower box (3), gate controlling organization (4) is to be made of the guide rail on the bottom surface that is arranged on lower box (3) (6) and 2 dollies (5), and dolly (5) can be gone up operation at guide rail (6) separately.Play the effect of closing 2 steel pipes (2).The lower surface of dolly (5) and steel pipe (2) is that the distance between the discharge port should reach 30 millimeters at least, at the middle part, bottom surface of lower box (3) 1 opening is arranged, and can communicate with preheater.

Working process of the present utility model is: 2 steel pipes (2) that are used for blanking, one is used for work, one is used for standby, Wingdale is injected in 1 steel pipe (2) wherein by charging tank (1), and drop in the lower box (3), dolly (5) in the gate controlling organization (4) is pushed a side to, the lower surface of promptly opening steel pipe (2) is a discharge port, Wingdale can enter in the preheater from lower box (3) smoothly, when occurring in the steel pipe (2) just at work that material blocks and when obstructed, 1 standby steel pipe (2) in addition then, dolly (5) in the gate controlling organization (4) of lower end is pushed a side to, promptly open steel pipe (2) lower surface discharge port, Wingdale is injected in this standby steel pipe (2) by charging tank (1), fall into lower box (3) and enter in the preheater, steel pipe (2) lower surface is that discharge port is 5 ° of oblique angles, and with apart at least 25 millimeters in dolly (5), purpose is when closing this discharge port, avoids oversize material stuck at this discharge port place.
