Description

Technical Field

[0001] The utility model relates to the technical field of feed screening, and specifically, to a flow tube sieve. Background Art

[0002] In the existing feed production process, before entering the finished product flow tube silo, the feed needs to be screened by a grading sieve device. However, during the process of the feed entering the finished product flow tube silo, it usually falls freely. Since the height of the finished product flow tube silo is relatively high, generally about 10 meters, this causes the feed to be easily broken when impacting the bottom of the silo, forming some dust, increasing the powder content rate of the feed, and degrading the quality.

[0003] However, if a vibrating sieve device is additionally installed after the finished product flow tube silo discharges, on the one hand, it occupies space, and on the other hand, it will increase the energy and maintenance costs. Summary of the Utility Model

[0004] To overcome the above defects, an embodiment of the utility model provides a flow tube sieve, aiming to solve the problems of high powder content rate and low quality of the feed product.

[0005] An embodiment of the utility model provides a flow tube sieve, which includes a flow tube silo, a first flow tube, a second flow tube, and a powder flow tube.

[0006] Among them, the flow tube silo includes a silo body, a silo door, and a screen. The length direction of the silo body is set at an angle of 45 degrees with the horizontal plane. The silo body has a receiving cavity. A silo door is opened on the side surface of the silo body. The screen is arranged in the receiving cavity parallel to the bottom surface of the silo body. An inlet is opened above the screen at one end of the silo body. An outlet and a powder outlet are respectively opened above and below the screen at the other end of the silo body. The upper end of the first flow tube is connected to the outlet flow tube, and the lower end of the first flow tube is connected to the inlet. The upper end of the second flow tube is connected to the outlet. The upper end of the powder flow tube is connected to the powder outlet.

The upper end of the first flow tube is connected to the outlet flow tube, and the lower end of the first flow tube is connected to the inlet. The upper end of the second flow tube is connected to the outlet. The upper end of the powder flow tube is connected to the powder outlet. Through the setting of this structure, the screening of the powder is realized by using the included angle between the material flow direction and the gravity direction, which can effectively reduce the powder content rate of the product and improve the quality of the finished feed.

It not only has a good powder reduction effect, but also saves more space compared with adding a vibrating screen device after the finished product flow pipe silo exits the bin. At the same time, it saves energy and maintenance costs. In previous production, the powder content rate of the feed was detected to be 2% through flow pipe sampling before entering the finished product logistics pipe silo, and the sampling result showed that the powder content rate increased to 4% when leaving the bin and being packed. After installing the flow pipe screen provided by the utility model at the exit section of the finished product flow pipe silo, the detected powder content rate is 2%. The device has a good powder reduction effect and can effectively improve the quality of the finished feed. Brief Description of the Drawings
