Description

Technical Field

[0001] The utility model relates to the technical field of wind feeding equipment, in particular to a feeding device for a powder selector. Background Art

[0002] Powder classifiers are widely used in coal mills, raw material intermediate unloading drying mills and cement mill systems in new dry process cement production lines. They can be divided into three categories: three-separation powder classifiers, centrifugal powder classifiers and cyclone powder classifiers. Most powder classifiers use wind feeding devices when running.

[0003] Most of the existing powder classifier feeding devices use wind to blow the powder directly into the powder classifier. However, the powder will adhere to the inner wall of the pipe due to static electricity and moisture. After long-term use, the attached powder will gradually accumulate, causing blockage, resulting in reduced conveying efficiency of the conveying device and affecting the operation of the powder classifier. To this end, we propose a powder classifier feeding device. Utility Model Content

During the transportation process, the screen and the vibration motor are used to shake off the powder attached to the inner wall and stuck in the holes of the screen to avoid blockage, and to facilitate the uniform separation of the powder into different channels.

[0008] Specifically, one end of the connecting passage away from the ventilation duct is connected through a material conveying rack, and a separation partition is fixedly installed at the center of the interior of the material conveying rack.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figure 1-3The embodiment of the utility model provides a technical solution: a powder selection machine feeding device, comprising a connecting channel 1, a feeding trough 2 is provided inside the connecting channel 1, a powder discharge pipe 4 is detachably installed inside the feeding trough 2, and the powder discharge pipe 4 is fixed and connected to the bottom end of the mounting frame 3, a feeding pipe 5 is connected to the top end of the mounting frame 3, and a vibration motor 9 is installed outside the bottom end of the connecting channel 1 below the feeding trough 2;

[0023] A ventilation duct 10 is connected through the side wall of the connecting channel 1. One end of the ventilation duct 10 away from the connecting channel 1 is connected through a chassis 11. An exhaust fan 12 is installed inside the chassis 11. A filter screen 13 is provided on the side wall of the exhaust fan 12.

[0024] When in use, the vibration motor 9 is operated to connect the channel 1 to allow the dust inside the feeding pipe to enter the feeding trough 2, and then the air supply mechanism is used to blow the powder in the feeding trough 2 into the feeding rack 8 and finally into the powder selection machine. During the transportation process, the screen and the vibration motor 9 are used to shake off the powder attached to the inner wall and stuck in the holes of the screen to avoid blockage, and to facilitate the uniform separation of the powder into different channels.

[0025] As shown in the figure, one end of the connecting channel 1 away from the ventilation duct 10 is connected through a material conveying rack 8, and a separation partition 7 is fixedly installed at the center of the interior of the material conveying rack 8.

[0026] When in use, different powder channels are separated by the separation partition 7 in the feeding frame 8 and sent into the powder selecting machine.

[0027] As shown in the figure, a guide frame 6 is fixedly installed at the connection between the connecting channel 1 and the material conveying frame 8.

[0028] When in use, the powder is guided by the guide frame 6 to enter the channel of the material conveying frame 8.

[0029] As shown in the figure, a screen is installed in the center of the guide frame 6 to facilitate the powder to pass through at a uniform speed.

[0030] When in use, the powder can pass through the screen evenly and at a uniform speed through the screen, and then pass through the separation partition 7 in equal amounts into different channels.

[0031] The working principle and use process of the utility model are as follows: first, the powder is transported to the inside of the connecting channel 1 through the feeding pipe 5, and the powder passes through the mounting frame 3 and the powder discharge pipe 4 to enter the inside of the feeding trough 2. Inside the feeding trough 2, the powder is prevented from adhering to the inner wall or the screen in the center of the guide frame 6 by the operation of the vibration motor 9. During the feeding process, the external air is filtered through the filter screen 13 and blown into the ventilation duct 10 by the operation of the exhaust fan 12 in the chassis 11, and finally the powder is blown into the connecting channel 1 and sent into the feeding frame 8. Under the screening and separation of the guide frame 6 and the separation partition 7 and the uniform separation by the vibration of the vibration motor 9, the powder enters the two channels in the feeding frame 8 and finally enters the powder selection machine.
