Description

Sintering feed bin sizing cleaning device

Technical Field

The utility model belongs to the technical field of the metallurgical industry sintering, especially, relate to a sintering feed bin sizing cleaning device.

Background

As shown in fig. 1, the distributing device of the sintering machine includes a shuttle distributor 100, a bin 200, a circular or wide belt feeder 300, and a nine-roll distributor 400.

The material distribution of the sintering machine requires the shuttle-type material distributor 100 to perform bidirectional reciprocating operation in the width direction of the storage bin 200, so as to uniformly distribute the sintering materials in the storage bin 200. The material surface is required to be smooth along the width direction of the trolley, the distribution density of the sintering material is required to be uniform, the sintering material is in a segregation distribution effect that the upper layer of the sintering material is fine in granularity and the lower layer of the sintering material is coarse in granularity along the height direction of the material layer of the trolley, the air permeability of the material layer is improved, the sintering of the thick material layer is realized, and the quality of sintered mineral products is improved.

The shape of the sintering bin 200 is a rectangular pyramid at the lower part of the upper cuboid, the height is 6-7 m, the sintering material is a mixture of iron ore powder, a flux, solid fuel and the like, the water content reaches 7-8%, particularly the sintering raw material structure with low silicon and high alkalinity and improved fine powder rate is adopted, the proportion of quick lime is large, the viscosity of the sintering material is large, the descending speed of the sintering material is slow, the stagnation time is more than 15min, and the bin sticking is easily caused.

The feed bin sizing makes material level 201 high on one side low in the storehouse, see figure 1, and the sintering material is under the gravity segregation effect, A end large granule material is many, cause feed bin discharge pressure and discharge amount unbalance, it differs to correspond sintering machine width direction production bed of material thickness, the ignition effect differs, sintering machine A end effect is serious and perpendicular sintering speed is fast, arrive the sintering end too early, the operation is difficult to control the platform truck width direction sintering speed unanimously, influence sintering process amount of wind and heat distribution inhomogeneous, the sintering mineral matter is poor.

When the material sticking of the bin is serious, the material shortage is serious within the range of 300mm corresponding to the A end of the sintering machine, the shutdown material cleaning times are increased, and the sintering capacity is reduced.

At present, the prior art mainly comprises the following four methods for cleaning the sticky materials in a material bin:

firstly, wall vibrators are installed on the outer walls of two sides of the lower portion of the storage bin, when the storage bin is seriously stuck, the low material level operation is controlled (the low material level influences the unstable blanking amount), and the wall vibrators are started to vibrate. The method has very limited treatment of the adhesive and insignificant effect. When the amount of the sticky materials is less, the sticky materials can fall off when the vibrator on the bin wall is started, and the vibrator cannot shake when the sticky materials are serious, so that the sticky materials are tighter and firmer by continuous vibration, and the vibration plays an opposite role.

And secondly, installing air cannons on the outer walls of two sides of the lower part of the stock bin, controlling the stock bin to run at a low material level (the low material level influences the unstable blanking amount), and starting the air cannons to shake regularly. The corresponding position of the air cannon has no binder, but the surrounding binders are gradually increased, the binder is relieved to a certain extent, but the effect is limited, only the binder period is relatively prolonged, and the binder still needs to be stopped frequently and manually treated.

Thirdly, mounting sound wave vibrators on two sides inside the bin, wherein the vibrators are downward opened and vibrate once at regular intervals. In a period of time after the material is removed from the storage bin, the material viscosity at the bottom of the storage bin is reduced to a certain extent, and the material viscosity at the upper part is more. With the time extension, the upper part binder is gradually increased, the bottom binder has more strain, the material cleaning period is prolonged, but the binder phenomenon still exists.

And fourthly, hanging material cleaning lining plates on two sides in the bin, controlling the bin to operate at a low material level, and periodically knocking the lining plates to remove the sticky materials. The method for cleaning the sticky materials has the advantages that the using effect is not ideal, the sticky materials on the hanging lining plate are very much, and the sticky materials are difficult to shake.

In summary, the existing method for cleaning the sticky materials in the material bin has the following defects and shortcomings: 1) only partially installing material cleaning facilities without full-area acting adhesive materials; 2) when the material cleaning facility is arranged outside the bin wall, the material is not directly acted as the adhesive material in the material cleaning process; when the material cleaning facility is statically suspended on the inner wall of the storage bin, materials impact the material cleaning facility when the materials are not cleaned, the material cleaning facility is fully adhered with the materials, and the material cleaning operation is difficult to perform; 3) the destructive power of the material cleaning facility to the adhesive material is extremely small, so that the adhesive material is more and more compact and serious and is difficult to clean.

Therefore, in the technical field of sintering in the metallurgical industry, there is still a need for research and improvement on the cleaning of the binder of the sintering bin, which is also a research focus and emphasis in the technical field of sintering in the metallurgical industry at present, and is the starting point of the present invention.
