Description

Technical Field

[0001] The utility model belongs to the field of sand and gravel powder selection, in particular to a sand and gravel powder selection machine with a quantitative feeding structure. Background Art

[0002] The sand and gravel powder classifier is a device that can perform powder selection and separation operations on sand and gravel. The powder selection principle of the sand and gravel powder classifier is to separate the sand and gravel mixture crushed in the previous process into different weights through high-pressure gas. When the sand and gravel powder classifier is in use, it needs to be continuously fed through the feeding device. The speed and amount of sand and gravel feeding determine the efficiency and quality of sand and gravel powder selection. Once the sand and gravel are fed too fast, it will cause sand and gravel accumulation, affecting the quality of screening. Feeding too little will increase the screening and separation costs and reduce the efficiency.

[0003] After searching, the Chinese patent application number is: 202210942096.8, which discloses a sand and gravel powder classifier with a quantitative feeding structure, including a powder classifier body, a quantitative roller, a vibration component, and a vibration component. A feed bin is vertically provided on one side of the upper end of the powder classifier body, and a feeding pipe is horizontally plugged into the upper end of one side of the feed bin. The quantitative roller is horizontally plugged into the lower end of the feed bin through a driving component, and a plurality of quantitative slots are symmetrically opened on the upper end of the quantitative roller. The vibration component is achieved by arranging a quantitative roller with a vibration component and a vibration component in the feed bin of the powder classifier body. The material fed into the feed bin is first accumulated in the bin, and the quantitative trough is quickly filled with sand and gravel under the action of the vibration component, and no cavitation occurs. The sand and gravel are transported at a uniform speed, and the amount of sand and gravel transported is consistent. In addition, the space occupied by the vibration component in the quantitative trough is controlled by the adjustment component to achieve the change of the amount of sand and gravel transported in a single time by the quantitative trough. The operation is simple, easy to use, and avoids the problem of feeding deviation such as sand and gravel accumulation. It has the following problems: the equipment lacks screening of the material entering the sand and gravel classifier, and large particles of material are easy to get stuck in the quantitative roller, causing the equipment to fail to work normally.

The metering barrel 6 and the output end of the motor 5 are fixedly connected, and a screen 8 is provided inside the feed bin 2. The inner wall of the feed bin 2 is fixedly connected to a spring 9, and the spring 9 is located between the screen 8 and the feed bin 2. The outer wall of the feed bin 2 is provided with a discharge port 11 matching the screen 8, and the lower surface of the screen 8 is fixedly connected to a vibration motor 10. The outer wall of the feed bin 2 is fixedly connected to a placement tray 12, and a collection frame 13 is placed on the upper surface of the placement tray 12.

[0019] It should be noted that, since the equipment lacks the method of screening the materials entering the sand and gravel powder classifier, large particles of materials are easily stuck in the metering roller, causing the equipment to not work properly. Therefore, in order to solve the problem that the equipment lacks the method of screening the materials entering the sand and gravel powder classifier, large particles of materials are easily stuck in the metering roller, causing the equipment to not work properly, this solution uses the screen 8 to screen the materials entering the feed bin 2 through the feed pipe 3. Large particles of materials are intercepted by the screen 8. Along the inclined screen 8, the large particles of materials fall from the right end of the screen 8 into the collection frame 13, and the large particles are sorted by the collection frame 13. The material is received and collected, and the vibration motor 10 is operated to make the screen 8 vibrate, thereby increasing the activity of the material on the upper surface of the screen 8 and improving the screening efficiency of the screen 8. The large-particle material is screened by the screen 8 to ensure the fineness of the material entering the discharge barrel 4, avoiding the large-particle material causing the metering barrel 6 to be unable to rotate, and ensuring the normal operation of the equipment. The material entering the powder classifier body 1 is quantified through the metering slot 7, and the metering barrel 6 can be turned over by the output end of the motor 5, so that the quantitative material in the metering slot 7 enters the powder classifier body 1.

[0020] In a further preferred embodiment of the present invention, Figure 2 As shown, an anti-clogging rod 16 is fixedly connected to the lower surface of the screen 8.

[0021] In this embodiment, the vibration of the screen 8 drives the anti-clogging rod 16 to vibrate above the quantitative groove 7, ensuring that the material in the feed bin 2 enters the quantitative groove 7 smoothly.

[0022] In a further preferred embodiment of the present invention, Figure 2 As shown, a baffle 14 is fixedly connected to the inner wall of the collecting frame 13 .

[0023] In this embodiment, the baffle 14 blocks the material discharged from the screen 8 , thereby preventing the material from the screen 8 from falling out of the collecting frame 13 .
