Description

Technical Field

[0001] The invention relates to a pulverizer, in particular to a pulverizing and separating device of a vertical shaft counter-impact pulverizer. Background Art

[0002] Currently used vertical mills and Raymond mills combine two devices, each with crushing and separation functions, within the same device. Specifically, the crushing and separation operations are located in separate areas within the same device. The O-SEPA classifier utilizes the centrifugal force generated by a rotating cage to keep coarse particles out of the cage, while the fan forces fine particles into the cage and out of the cavity. Currently used vertical hammer crushers and vertical impact crushers have their crushing rotors mounted sequentially on a single rotating shaft. Material is fed into the crusher from a hopper and then pulverized by each of the crushing rotors before being discharged from the cavity. However, these crushers lack the ability to separate coarse and fine materials, and the crushing rotors lack the ability to coordinate with each other to achieve ultra-fine pulverization. This results in poor pulverization, an inability to control the fineness of the output material, low efficiency, and high waste. Summary of the Invention

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0026] Reference Figures 1 to 4 As a first embodiment of the present invention, a pulverizing and separating device for a vertical shaft counter-acting pulverizer is provided, comprising a housing 7; an upper cover 2 is mounted on the housing 7; a feed hopper 1 and an air inlet 4 are provided on the upper cover 2; a base 17 is mounted on the bottom of the housing 7; a lower hopper 19 and an air duct 15 connected to a fan are provided on the base 17; a high-speed rotating pulverizing rotor 9 and a pulverizing and separating rotor 21 are mounted within the housing 7; the air duct 15 is used to connect the pulverizing and separating rotor 21 to the fan;

[0027] The pulverizing rotor 9 and the pulverizing and separating rotor 21 are used for ultra-fine powdering of materials. The powders of different finenesses are separated together with the pulverizing and separating rotor 21 by controlling the air volume and air pressure of the fan.

[0028] Specifically, the crushing rotor 9 and the crushing and separation rotor 21 rotate at high speed, so that the material is repeatedly circulated and crushed between the crushing rotor 9 and the crushing and separation rotor 21, and the fan is used to make the casing 7 generate wind force and wind pressure negative pressure, so that the fine powder material passes through the through holes on the crushing and separation rotor 21, thereby achieving the required fineness requirement.

[0029] The upper cover 2 is provided with a shaft A5 and a sleeve A6; the grinding rotor 9 is connected to the pulley A3 providing external rotational power via the shaft A5;

[0030] The crushing rotor 9 is composed of a rotor A23 and a plurality of hammers 10; the upper and lower end surfaces of the rotor A23 are provided with a plurality of grooves;

[0031] The striking hammer 10 is installed in a groove of the rotor A23.

[0032] Specifically, the material enters from the top feed hopper 1 and falls onto the crushing rotor 9, thereby being crushed by the impact hammer 10; the pulley A3 is connected to the motor that provides power through a belt.

[0033] The base 17 is provided with a shaft B16 and a sleeve B20; the crushing and separating rotor 21 is connected to a pulley B18 providing external rotational power via the shaft B16; the crushing and separating rotor 21 is provided with a plurality of through holes;

[0034] The crushing and separation rotor 21 includes a rotor 13 and an inclined wear-resistant separation plate 22 mounted on the rotor 13;

[0035] The inclined wear-resistant separation plate 22 is provided with a guide plate 12 , and the guide plate 12 is provided with a guide plate.

[0036] Specifically, after the material is crushed by the crushing rotor 9, it further falls onto the crushing and separation rotor 21. Under the action of the inclined wear-resistant separation plate 22, the material is repeatedly circulated and crushed in the crushing rotor 9 and the crushing and separation rotor 21. The function of the guide plate 12 and the guide plate is to guide the material into the inclined wear-resistant separation plate 22.

[0037] The inclined wear-resistant separation plate 22 is in a fan-shaped structure; a trapezoidal wear-resistant block 24 is provided on the inclined wear-resistant separation plate 22 .

[0038] Specifically, the trapezoidal wear-resistant blocks 24 will throw up the materials that fall onto the inclined wear-resistant separation plate 22 under the action of rotation, thereby achieving repeated cyclic crushing in the crushing rotor 9 and the crushing separation rotor 21.

[0039] A retaining ring 11 is installed on the inner wall of the housing 7 to separate the crushing rotor 9 and the crushing and separation rotor 21;

[0040] The inner wall of the casing 7 is provided with a lining plate A8 and a lining plate B14 above and below the retaining ring 11 respectively.

[0041] Specifically, the function of the retaining ring 11 is to better guide the material onto the inclined wear-resistant separation plate 22, thereby increasing the reliability of the repeated circulation crushing of the material in the crushing rotor 9 and the crushing separation rotor 21; the function of the liner A8 and the liner B14 is to protect the casing 7.

[0042] The center lines of the axis A5 and the axis B16 coincide with each other. This technical feature further constrains the axes of the crushing rotor 9 and the crushing and separation rotor 21 to coincide with each other or be on the same straight line, thereby ensuring that the material can be repeatedly crushed to the required fineness.

[0043] Working principle: The motor provides power to pulley A3 and pulley B18 to drive the corresponding shaft A5 and shaft B16 to rotate, and at the same time starts the fan to feed the material. After the material is crushed by the crushing rotor 9, it falls into the inclined wear-resistant separation plate 22 on the crushing and separation rotor 21. The guide plate 12 and the guide plate guide the material to fall onto the inclined wear-resistant separation plate 22. The trapezoidal wear-resistant block 24 will throw the material that falls on the inclined wear-resistant separation plate 22 under the action of rotation, thereby realizing repeated cycle crushing in the crushing rotor 9 and the crushing and separation rotor 21. By adjusting the air volume and wind pressure of the fan, the fine powder material passes through the through hole on the rotating crushing and separation rotor 21 under the action of wind force and wind pressure, and is discharged from the casing 7 through the induced air duct 15, realizing the separation of materials of different fineness after crushing.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
