Technical Field

The utility model relates to a vertical mill technical field particularly, relates to a seal device of sediment department is arranged to vertical mill.

Background

The vertical mill is a large-scale grinding device and is widely applied to industries such as cement, electric power, metallurgy, chemical industry, non-metal ore and the like. It integrates crushing, drying, grinding and grading conveying into a whole, has high production efficiency, and can grind blocky, granular and powdery raw materials into required powdery materials. The slag formed when the vertical mill works is discharged through a slag discharge pipe arranged on one side.

A double-layer turning plate air locking valve is generally arranged at the slag discharging position of the vertical mill for locking air, and the blanking function is realized; some vertical mills are also provided with a vibration feeder to form a material column by controlling the flow rate, so that the functions of air locking and blanking are achieved. These devices are not ideal in effect from the present, and are mainly reflected in: the double-layer flap valve often causes air locking failure because slag particles enter a joint of the shaft and the valve plate and are blocked, so that air leakage at a slag discharge port of the vertical mill is caused, the internal air speed of the vertical mill is reduced, and finished products cannot be taken away by air flow in time, so that the power consumption of equipment is increased, the yield of the vertical mill is reduced, and the normal operation of the equipment is influenced; the use of vibration feeding machine can bring certain noise problem because of its vibration frequency, also need carry out the full-sealed just can not produce the raise dust during the use, needs certain power consumption simultaneously, and the installation also needs great space.

SUMMERY OF THE UTILITY MODEL

The utility model provides a sealing device who immediately grinds sediment department to not enough in the background art. Through the utility model discloses can realize immediately grinding the stable ejection of compact and the effective lock wind of arranging sediment department.

In order to achieve the above object, the technical solution of the present invention is as follows: the utility model provides a seal device of sediment department is arranged to vertical mill, includes the scum pipe, the mouth of pipe department of scum pipe is equipped with segmentation airlock, segmentation airlock upper end is articulated with the mouth of pipe upper end of scum pipe, the total four sections of segmentation airlock just pass through hinge connection, the scum pipe below is equipped with the conveyer belt.

In order to ensure that the multi-section wind locking plate arranged at the position of the slag discharging pipe has good wind locking effect by means of the gravity of the multi-section wind locking plate attached to the plane of the pipe opening of the slag discharging pipe, the invention provides another preferable scheme. The included angle between the pipe orifice plane of the slag discharge pipe and the vertical plane is 10 degrees close to the machine body. And the negative pressure of about 1100Pa inside the vertical mill works together to play a good air locking effect on the slag discharge pipe.

In order to adjust the accumulation height of the waste residues at the pipe orifice of the slag discharge pipe during working so as to ensure that the waste residues form a certain material column in front of the air locking plate to achieve the air locking effect, the invention provides another preferable scheme. And a material level sensor is arranged on the inner wall of the slag discharging pipe. The level sensor is a radar level sensor commonly used in the prior art, and is not described herein.

In order to accumulate the waste slag with a certain height between the slag discharging pipe and the conveying belt and connect the waste slag with the waste slag at the pipe opening of the slag discharging pipe into a whole to block the pipe opening of the slag discharging pipe to form an air locking structure, the invention provides another preferable scheme. The distance between the bottom end of the pipe orifice of the slag discharge pipe and the upper surface of the conveying belt is 40-60 mm.

In order to reduce the dust overflow in the deslagging process, the invention provides another preferable scheme. The conveying belt is characterized in that a casing is arranged outside the conveying belt, and a feeding hole and a discharging hole are sequentially formed in the casing along the conveying direction of the conveying belt.

Generally, through the utility model discloses above technical scheme who conceives compares with prior art, can gain following beneficial effect:

1. the multi-section air locking plate is adsorbed at the pipe orifice of the slag discharging pipe by utilizing the combined action of the self gravity of the multi-section air locking plate and the negative pressure in the vertical mill, so that the air locking effect is achieved.

2. Different sections are opened by the multi-section wind locking plate connected with the hinge at different speeds of the conveyor belt, so that the feeding stability and the optimal wind locking effect are both considered.
