Abstract

The utility model discloses a balling disc water jet equipment relates to the balling disc field, provides an effectual balling disc water jet equipment of water spray. The water spraying device of the disc pelletizer comprises a water spraying pipe and a spray head connected with the water spraying pipe, and further comprises a compressed air pipe connected with the water spraying pipe. Wherein, the spray pipe is provided with a spray water control valve, and the compressed air pipe is provided with a spray air control valve; the included angle between the compressed air pipe and the water spray pipe is a, and a is less than or equal to 60 degrees. The utility model discloses compressed air pipe and spray pipe are connected, and the shower nozzle blowout is followed to steam after the intraductal mixture of spray. The compressed air increases the water pressure, which is beneficial to the atomization of water; compressed air can further blow away water, improves the atomization effect. Under the less condition of water pressure, the utility model discloses an effect is more obvious.

Description

Water spraying device of disc pelletizer

Technical Field

The utility model relates to a balling disc field especially relates to a balling disc water jet equipment.

Background

The disk pelletizer is disk pelletizing equipment for pelletizing fine powder material into spherical material with granularity meeting the requirement of the next operation, and is used in the production of iron smelting pellet in metallurgical industry and pelletizing operation of mixed non-ferrous metal concentrate to raise the economic indexes of smelting technology. The pelletizing material is acted by gravity, centrifugal force and friction force in the inclined and rotating disc to produce rolling and twisting, and after proper water content is replenished, mother ball is formed. The fine grained material rolls on the wet surface of the cue ball, so that the cue ball grows and has certain strength. The different pellets automatically follow different trajectories in the disk from which the finished pellets that meet the requirements are discharged.

As mentioned above, water needs to be sprayed in the production process of the disc pelletizer, and the water is required to be uniformly sprayed and have fine water drops in a certain range of the disc. The water spraying device of the existing disc pelletizer comprises a water spraying pipe and a spray head connected with the water spraying pipe. The spray head is a common mechanical atomization spray head, the atomization effect of the spray head on water is poor, and particularly under the condition of low water pressure, the spray head is similar to dripping water, and the production speed and quality of pellets are influenced.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: provides a water spraying device of a disc pelletizer with good water spraying effect.

The technical scheme adopted for solving the problems is as follows: the water spraying device of the disc pelletizer comprises a water spraying pipe and a spray head connected with the water spraying pipe, and further comprises a compressed air pipe connected with the water spraying pipe.

Further, the method comprises the following steps: the water spray pipe is provided with a water spray control valve, and the compressed air pipe is provided with a water spray control valve.

Further, the method comprises the following steps: the included angle between the compressed air pipe and the water spray pipe is a, and a is less than or equal to 60 degrees.

The utility model has the advantages that: the utility model discloses compressed air pipe and spray pipe are connected, and the shower nozzle blowout is followed to steam after the intraductal mixture of spray. The compressed air increases the water pressure, which is beneficial to the atomization of water; compressed air can further blow away water, improves the atomization effect. Under the less condition of water pressure, the utility model discloses an effect is more obvious. Therefore, the utility model discloses can improve the water spray effect, do benefit to and evenly spray tiny water droplet in the certain region of disc to improve the production speed and the quality of pelletizing.

Drawings

FIG. 1 is a schematic structural diagram of a water spraying device of a disc pelletizer;

labeled as: a spray pipe 1, a spray head 2, a compressed air pipe 3, a spray water control valve 4 and a spray air control valve 5.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1, the water spraying device of the disc pelletizer comprises a water spraying pipe 1 and a nozzle 2 connected with the water spraying pipe 1, and further comprises a compressed air pipe 3, wherein the compressed air pipe 3 is connected with the water spraying pipe 1.

The utility model discloses compressed air pipe 3 is connected with spray pipe 1, and the shower nozzle blowout is followed to steam after mixing in spray pipe 1. The compressed air increases the water pressure, which is beneficial to the atomization of water; compressed air can further blow away water, improves the atomization effect.

In order to further make the water spray effect adjustable, the utility model discloses set up on preferred spray pipe 1 and spout water control valve 4, be provided with on compressed air pipe 3 and spout air control valve 5. The opening degrees of the water spray control valve 4 and the water spray control valve 5 are adjusted, and the input water-air ratio can be adjusted, so that the atomization effect is adjusted, and the water spray quantity and the atomization effect of water are optimized.

Compressed air should obviously spout to 2 directions of shower nozzle, and compressed air pipe 3 should not be too big with the contained angle of spray pipe 1, the utility model discloses preferred compressed air pipe 3 is a with the contained angle of spray pipe 1, and a is less than or equal to 60.
