Description
Technical Field
The invention belongs to the technical field of chemi-mechanical pulp wood chip preheating equipment, and particularly relates to an anti-bridging groove body of a steaming bin.
Background
At the present stage, as the country restricts the import of waste paper, the waste paper raw material cannot be fully supplemented. At present, many domestic paper making enterprises are in transformation and upgrading, and the chemical pulp line has large investment scale and is more strict in approval. Therefore, many paper making enterprises now tend to invest in chemi-mechanical pulp production lines. The production process of the chemical mechanical pulp production line necessarily needs wood chip pre-steaming equipment to pre-treat wood chips, so that the subsequent process treatment is facilitated. At the moment, the wood chip pre-steaming equipment is particularly important, but the wood chips enter the steaming bin body in a sheet form and stay in the bin body for a certain time, so the height of the steaming bin body is generally higher. Because the wood chips entering the bin are dry, the wood chips can expand rapidly and become larger in volume after encountering steam.
The steaming bin body is generally higher in height, the internal general stacking height is larger, the steaming bin body is easily compacted with the internal part of the steaming bin body after the volume of wood chips is increased, and a material receiving cone at the bottom upwards forms an integral wood plug to form a bridge. The wood chip bin cannot normally discharge materials, and personnel are required to enter the bin body for maintenance after the material collecting cone in the conventional steaming bin is used for effectively increasing the volume rate of the bin body and bridging, so that the operation of the whole production line is influenced, and the danger and the time consumption are reduced.
In the application field of the current steaming bin, two main forms of a groove body are provided, namely a straight cylinder form and a right frustum form. The current tank body design form mainly has the following problems: 1. firstly, both the two forms have the problem of wood chip bridging, because the wood chip needs to be preheated and soaked by steam and water after entering the steaming bin, the surface of the wood chip can be adhered to the inner wall of the slot body at the moment, the bottom of the bin bottom and the circumferential space can be smaller and smaller along with the increase of time, and after a certain time, the wood chip can be compacted with the inner wall under the action of the horizontal pressure generated by the material with the height larger than the natural height and the self-swelling to form the bridging.
Whether the bridge is formed or not in the cone structure is mainly related to the taper of the groove body. Practice shows that if the inner wall of the bin is smooth, and the taper of the frustum structure is smaller than 30 degrees, the wood chip surface still adheres to the inner wall of the groove body due to poor flowability of the wood chips, and finally bridging is caused under the combined action of self moistening tension and pressure, the bridging period is only longer than that of a straight cylinder, but the waste of workshop site space is larger. However, if a larger taper is used, a large portion of the volume (the same floor area, the same height of contrast) is lost and the residence time is uneconomical.
