Papermaking raw material conveying device with screening function

Abstract

The invention discloses a papermaking raw material conveying device with a screening function. The papermaking raw material conveying device comprises: a first conveyor belt, wherein baffle plates are vertically arranged on the two sides of the first conveyor belt to form an accommodating space with an opening in the top with the first conveyor belt, and the first conveyor belt is arranged horizontally with one end as an output end; a second conveyor belt, wherein the second conveyor belt inclines by 25-35 degrees with respect to the ground, and a lower end of the second conveyor belt is overlapped below the output end of the first conveyor belt; and a third conveyor belt, wherein the third conveyor belt inclines by 40-50 degrees with respect to a bottom surface, and a lower end of the third conveyor belt is arranged below a higher end of the second conveyor belt to receive dropping materials. The papermaking raw material conveying device is integrated with conveying and screening, simple in structure, good in screening effect, and time-saving and labor-saving. The papermaking raw material conveying device firstly layers papermaking raw materials while conveying the raw materials, and separates out the raw materials relatively large in volume first before separating impurities from the raw materials, and therefore, a separation effect is improved. A pillar of the papermaking raw material conveying device is a telescopic pillar so that an inclination and a conveying height can be effectively adjusted.

Description

technical field [0001] The invention relates to the field of delivery devices. More specifically, the present invention relates to a papermaking stock conveying device with a screening function. Background technique [0002] Papermaking raw materials can be obtained by mechanically pulverizing raw wood or wood. However, during the pulverization or transportation of raw wood and wood, some stones or metals are often mixed in. These stones and metals affect the quality of papermaking raw materials. Therefore, before using papermaking raw materials, it is necessary to screen out these impurities such as stones and metals. [0003] The traditional method is to use the screening device to screen the paper-making raw materials first, and then send the paper-making raw materials to the designated place through the conveying device. However, this method not only has many procedures and takes a long time, but also has a complicated structure. Therefore it is imperative to design an...

[0005] However, this kind of conveying equipment can only separate the sundries that are quite different in weight from the papermaking raw materials. Some sundries with small volume and weight equivalent to the papermaking raw materials are not isolated by these parabolic separation and inertial separation. Although these sundries are relatively large in size Small, but the gravity is equivalent to that of larger papermaking raw materials, so when performing parabolic separation and inertial separation, this part of debris will still be mixed with the larger papermaking raw materials and cannot be separated
