摘要： In accordance with the present invention a hopper outlet is provided including transversely spaced, fixed racks on opposite sides of the outlet which extend longitudinally away from the outlet. At least one door bearing is attached to the outer end of a generally horizontally moving outlet gate. A ramp including an inclined cam surface is located below the inner outlet end wall. U-shaped elastomeric seals extend below the outlet sides and end walls and the lower leg of the seal engages the gate. A transversely extending pinion shaft includes pinions which ride upon the racks in moving between open and closed position. The pinion shaft extends through a slot in the door bearing. The slot is elongated vertically to allow vertical movement of the gate and the door bearing relative to the pinion shaft as the gate is ramped upwardly into closed position and downwardly into open position.

摘要： A fluidizing outlet is provided having plenum sheets which define with the sides of the bottom pan of the outlet a plenum chamber. At least a portion of the lower edges of the plenum sheets are spaced from the sides of the bottom pan a suitable distance to provide gaps which form first fluidizing openings. Openings are provided in the upper portion of the plenum sheets to provide second fluidizing openings to fluidize the lading. The respective sizes of the first and second fluidizing openings are of a size sufficient to fluidize the lading, and are sufficiently large that they are not readily clogged by contaminates; for example, from dirty supply air and/or improper outlet cleaning to prevent operation of the outlet, and of a size sufficient that substantially all of the lading is removed during unloading. It has been found that the spacing between the outlet pan and the plenum sheets forming the first fluidizing openings should be at least about 0.03 inches, and should not exceed about 0.04 inches. It has further been found that the openings in the plenum sheets forming the second fluidizing openings should have a cross-sectional area of at least about 0.002 in..sup. 2, and should not exceed about 0.004 in..sup.2. The second fluidizing openings should be spaced from each other within the range 0.75 to about 1.25 inches.
摘要翻译： 设置有流化出口，其具有限定在出口的底盘侧面的增压室。 增压板的下边缘的至少一部分与底盘的侧面间隔适当的距离以提供形成第一流化开口的间隙。 开口设置在增压板的上部，以提供第二流化开口以使提货流化。 第一和第二流化孔的各自尺寸的尺寸足以使提质流化，并且足够大，使得它们不容易被污染物堵塞; 例如，从脏的供应空气和/或不当的出口清洁以防止出口的操作，以及足够的尺寸，使得在卸载期间基本上所有的提单都被移除。 已经发现出口盘和形成第一流化开口的增压板之间的间隔应该是至少约0.03英寸，并且不应该超过约0.04英寸。 进一步发现形成第二流化开口的增压板中的开口应具有至少约0.002英寸2的横截面积，并且不应超过约0.004英寸。 第二流化开口应在0.75至约1.25英寸的范围内彼此间隔开。

摘要： A gravity outlet suitable for hoppers is provided comprising a gate movable back and forth between open and closed positions. A locking shaft is mounted on the gate having handles on at least one side of the outlet and having a locking member preferably hook shaped mounted thereon. A locking lug and a tripping lug are affixed to the pans or frame structure of the outlet. In order to open the gate the locking shaft is rotated to move the locking member to a position out of engagement with the locking lug thus allowing the gate to move outwardly from the pans. As the gate travels towards the open position, the tripping lug trips the locking member into a tripped position where it rides to the open position with the gate. Stops are provided to stop the gate in the full open position. During closing of the gate, a cam surface on the locking member travels up the locking lug and then the locking member drops into the locked position automatically to maintain the gate in a closed and locked position. In one embodiment a pinion shaft having pinions thereon and at least one door bearing are affixed to the gate which carry the gate along a fixed rack. In another embodiment a rack is affixed to the gate which is driven by a rotatable but longitudinally fixed pinion and pinion shaft. In accordance with another embodiment of the present invention, the locking shaft is movable into an overcenter position to provide further assurance to maintain the gate in the closed position. In another embodiment a transversely extending elastomeric seal is affixed either to the gate pan or to the gate. In one embodiment the elastomeric seal maintains contact with the gate regardless of the gate position to facilitate sealing during unloading. In another embodiment the elastomeric seal is in contact with the gate pan only in the closed position. In accordance with another embodiment at the front of the gate, gate guides are provided to insure that the gate assumes and maintains a closed position in engagement with the front pan.
