Description

Technical Field

[0001] The utility model relates to the field of V-shaped powder classifiers for cement grinding, and in particular to a V-shaped powder classifier for cement grinding. Background Art

[0002] V-type powder classifier is a powder mixing equipment widely used in pharmaceutical, chemical, food and other fields. It is mainly used to evenly mix powder raw materials of different particle size, density, specific gravity and color. V-type powder classifier usually has two rotating barrels or one barrel and a rotating blade. The inner wall of the barrel is usually smooth to facilitate the mixing and flow of powder. In the V-type powder classifier, multiple rotating blades or agitators are usually installed, which are responsible for mixing the powder materials. The design and rotating motion of these blades help to evenly disperse and mix the powder together. Through its efficient and uniform mixing method, it provides important technical support for the production of various powder raw materials, helping enterprises to improve production efficiency and product quality.

[0003] In the specific process of cement powder grinding and selection, although the conventional device can use grading blocks to select cement powder, it is unable to continuously grind the cement powder during the selection process, thereby affecting the selection of cement powder. In addition, when the cement powder is selected, it cannot be directly used in conjunction with the packaging device after the labeling is completed, which is insufficient in practicality.

The cement enters the interior of the powder classifier body 11, and through the continuous movement of the cement, the cement can be diverted through the grading block 18, and the cement can be limited, and the cement can be left on the top of the grading block 18, so that the cement and the wind inside the powder classifier body 11 are in full and effective contact, thereby improving the powder selection efficiency. Then, when the operator introduces the gas into the air inlet duct 13, the operator can start the motor 15 to drive the grinding roller 17 to rotate, thereby increasing the speed of the gas, so that the gas has a better powder selection effect on the cement, and the rotation speed of the grinding roller 17 can be controlled, and cement of different particle sizes can be ground out according to actual needs, so that the cement powder can be continuously ground and selected, thereby improving the powder selection effect of the cement powder.

[0027] Reference Figure 1-Figure 4 In a preferred embodiment, a conveying device 2 is provided on the top of the mounting frame 12, an air inlet pipe 13 is provided on one side of the powder classifier body 11, a limit frame is fixedly installed inside the mounting frame 12, and the limit frame is provided to improve the stability of the motor 15. The motor 15 is arranged inside the limit frame, a conveying fence 22 is provided on the top of the powder classifier body 11, a feed hopper 21 is provided on the top of the conveying fence 22, a feed pipe 14 is provided on the other side of the powder classifier body 11, and a powder discharge pipe 23 is provided at the bottom of the powder classifier body 11. The powder discharge pipe 23 is provided below the motor 15. A feed trough 19 is provided on one side, and the feed trough 19 is connected to the conveying fence 22. Through the cooperation between the conveying device 2 and the powder discharge pipe 23, when the operator needs to directly package the cement after powder selection, the operator can start the conveying device 2 and transport the labeled packaging bags. When the packaging bags are transported to the powder discharge pipe 23, the operator can directly open the packaging bags. Finally, the operator can open the powder discharge pipe 23, so that the cement after powder selection can be packaged into the interior of the packaging bags, etc., and then it can be directly used in conjunction with the packaging device after labeling, thereby improving the practicality of the device.

[0028] Reference Figure 1-Figure 4In a preferred embodiment, the grading block 18 and the grinding roller 17 are arranged to intersect with each other, and one side of the inner cavity of the conveying bar 22 is arranged in a sloped shape, thereby improving the conveying efficiency of the conveying bar 22. The conveying device 2 is arranged below the powder classifier body 11, and the feed hopper 21 is arranged on the top of the mounting frame 12. The conveying device 2 includes a conveyor belt. By arranging the conveyor belt, a servo motor and a mounting rod, the mounting rod is fixed to the output end of the servo motor, and the conveyor belt is arranged on the surface of the mounting rod. By arranging the conveying device 2, the labeled packaging bags can be conveyed, and the conveyor belt is arranged directly below the powder classifier body 11.

[0029] Specifically, the working process or working principle of the V-type powder classifier for cement grinding is as follows: in the specific cement grinding and powder selection, although the conventional device can use the grading block 18 to select the cement powder, it is impossible to continuously grind the cement powder during the powder selection process, which affects the powder selection of the cement powder, and the cement powder cannot be directly used in conjunction with the packaging device after the labeling is completed during the powder selection, which is not practical enough. Therefore, the present technical solution can solve the above problems. When the operator needs to use it in practice, he can first put the cement from the feed hopper 21 into the inside of the conveying fence 22, and then the cement can enter the inside of the powder classifier body 11 through the feed trough 19. Through the continuous movement of the cement, the cement can be diverted through the grading block 18, and the cement can be limited to stay on the top of the grading block 18, so that the cement and the wind inside the powder classifier body 11 are fully and effectively in contact, thereby improving the powder selection efficiency. The operator then guides the gas into the air inlet pipe 13, and at this time the operator can start the motor 15 to drive the grinding roller 17 to rotate, thereby increasing the speed of the gas, so that the gas has a better effect on the selection of cement powder, and the rotation speed of the grinding roller 17 can be controlled, and cement of different particle sizes can be ground according to actual needs, so that the cement powder can be continuously ground and selected, thereby improving the selection effect of the cement powder. When the operator needs to directly package the cement after powder selection, the operator can start the conveying device 2 to convey the labeled packaging bags, etc., and when it is conveyed to the powder discharge pipe 23, the operator can directly open the packaging bags, etc., and finally the operator can open the powder discharge pipe 23, so that the cement after powder selection can be packed into the packaging bags, etc., and then it can be directly used in conjunction with the packaging device after labeling, thereby improving the practicality of the device, and all processes are ended here.

[0030] It should be noted that the powder classifier body 11 and the motor 15 are both electrically connected to an external power supply and are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
