Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of industrial humidifiers, and particularly relates to a rolling dust humidifier. Background Art
[0002] Dust humidifiers are divided into single-roll humidifiers and double-roll humidifiers according to the number of mixing rolls, and are further divided into co-rotating double-roll humidifiers and counter-rotating double-roll humidifiers according to the rotation direction of the two mixing rolls. Dust humidifiers are applicable to the humidification, mixing and conveying of solid materials, especially powder materials, in chemical plants, power plants, mines, steel plants, etc. Dust humidifiers belong to dust removal auxiliary equipment and are mainly used for humidifying and mixing dry ash in powder silos to meet the requirements for external transportation.
[0003] In the existing counter-rotating dust humidifier, the mixing roll is generally in the shape of a long roll with blades. The mixing effect and conveying capacity are not high. The mixing roll in the form of blades requires a high rotation speed, otherwise the mixing effect is poor. However, a high rotation speed leads to a weak rotation torque and cannot humidify a large amount of materials in a short time. Summary of the Utility Model
[0004] Therefore, the utility model provides a counter-rotating dust humidifier to improve the efficiency of humidifying and mixing powder materials, reduce dust adhesion inside the humidifier, and reduce the frequency of cleaning and maintenance of the humidifier.
[0005] The technical solution of the utility model is as follows:
[0006] A counter-rotating dust humidifier includes a base, a motor, a coupling, a speed reducer, a mixing roll and a rolling chamber. The motor, the speed reducer and the rolling chamber are all arranged on the base, and the motor, the coupling, the speed reducer and the mixing roll are connected in sequence;
[0007] The number of the mixing rolls is two and they are arranged horizontally side by side. The mixing rolls are located inside the rolling chamber, and the rotation directions of the mixing rolls are opposite. The outer surface of the mixing roll is provided with a helix and mixing teeth;
[0008] An inlet is opened above one end of the rolling chamber close to the speed reducer. A water nozzle for spraying water inward is arranged above the upper part of the rolling chamber near the inlet and far from the speed reducer. A plurality of water nozzles are arranged along the axial direction of the rolling chamber. A discharge port is opened at the bottom of one end of the rolling chamber far from the coupling. Elastic columns are arranged inward on the inner wall side of the rolling chamber and point to the mixing roll. The free ends of the elastic columns are in contact with the surface of the mixing roll.
[0009] As a preference, the elastic column is a solid rubber column, and the plane where the axis of the elastic column is located is higher than the plane where the axis of the mixing roll is located.
[0010] As a preference, the inside of the elastic column is a spring and the outside is coated with rubber, and the plane where the axis of the elastic column is located is higher than the plane where the axis of the mixing roll is located.
[0011] As a preference, the coupling is a slider coupling, the reduction gearbox is a gear reduction gearbox, and the motor is a three-phase asynchronous motor.
[0012] The working principle and beneficial effects of the present utility model are as follows:
[0013] For the roll-type dust humidifying machine provided by the present utility model, dust materials are input from the feed inlet, and the motor drives the stirring roll to rotate after being decelerated by the reduction gearbox. The dust materials are fully mixed under the action of the stirring of the stirring roll, and are gradually pushed forward under the spiral action. The water nozzle above sprays water to humidify the dust materials. At the same time, the materials are continuously stirred and pushed forward, and are pushed to the discharge port to fall and be discharged, completing the entire humidifying process. During the whole process, the elastic columns pat the stirring roll to pat off the wet materials adhered to the stirring roll, playing an auxiliary cleaning role. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] This embodiment provides a roll-type dust humidifying machine, which includes a base 1, a motor 2, a coupling 3, a reduction gearbox 4, a stirring roll 6 and a rolling chamber 5. The motor 2, the reduction gearbox 4 and the rolling chamber 5 are all arranged on the base 1, and the motor 2, the coupling 3, the reduction gearbox 4 and the stirring roll 6 are connected in sequence.
[0020] The number of the stirring rolls 6 is two and they are arranged horizontally in parallel. The stirring rolls 6 are located in the rolling chamber 5, and the rotation directions of the two stirring rolls 6 are opposite. The outer surface of the stirring roll 6 is provided with a spiral and stirring teeth.
[0021] Above the upper end of the rolling chamber 5 near the speed reducer 4, there is a feed inlet 51. Above the upper part of the rolling chamber 5 near the feed inlet 51 and away from the speed reducer 4, there are water nozzles arranged axially along the rolling chamber 5 for spraying water inward. At the bottom of the rolling chamber 5 at the end far from the coupling 3, there is a discharge port 52. On the inner wall side of the rolling chamber 5, there are elastic columns 53 arranged inward, and the elastic columns 53 point to the stirring roller 6, with the free ends of the elastic columns 53 in contact with the surface of the stirring roller 6. A preferred way for the elastic columns 53 is to use solid rubber columns. The axis of the fixed end of the elastic column 53 is higher than the axis of the stirring roller 6, and the elastic columns 53 mainly use their elasticity to pat the upper surface of the stirring roller 6. Another preferred setting method for the elastic columns 53 is to use a spring covered with rubber on the outside. In this setting method, the fixed end of the elastic column 53 is more firmly combined with the rolling chamber 5, and since rubber is an easily aging material, it is convenient to replace. At this time, the axis of the elastic column 53 is still higher than the plane where the axis of the stirring roller 6 is located, and the elastic column 53 contacts and pats the upper surface of the stirring roller 6.
[0022] In this embodiment, the motor 2 uses a three-phase asynchronous motor. This type of motor is widely used, has simple control, and low failure rate. If a speed regulation function needs to be achieved, a frequency converter can also be added. The motor 2 can also use other types of motors such as three-phase synchronous motors or DC motors. Preferably, the coupling 3 for transmission between the motor 2 and the speed reducer 4 uses a slider coupling. Preferably, the speed reducer 4 uses a gear speed reducer, which can withstand a large torque.
[0023] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
