Technical Field

The utility model relates to a strong calcium oxide production facility field, specific hardened material breaker that is used for calcium hydrate to weigh before the packing that says so.

Background

In the process of weighing and bagging calcium hydroxide, a belt conveyor is generally used to convey calcium hydroxide from a silo storing the calcium hydroxide to a weighing and bagging device. In actual production, the calcium hydroxide finished product which is normally powdery in a silo is easy to harden to form a plate caking material. After the plate materials are conveyed to the weighing and packing equipment along with the belt conveyor, the plate materials are prone to blocking of pipelines inside the weighing and packing equipment. Resulting in interruption of packaging production and requiring manual maintenance. Even if blockage is not generated, the self weight of the blocky hardened materials is large, and the large caked calcium hydroxide directly falls into a finished product packaging bag through a packaging weighing device, so that weighing errors are caused.

Detailed Description

As shown in figure 1, the plate caking material crushing device used before weighing and packing calcium hydroxide comprises a frame 13, wherein a belt conveyor 12 and a crushing mechanism are arranged on the frame 13. The conveying direction of the belt conveyor 12 is from left to right, the left end of the belt conveyor is connected with a silo for storing calcium hydroxide finished products, and the right end of the belt conveyor is connected with weighing and packing equipment. The crushing mechanism is provided at a position above the middle of the belt conveyor 12 and is used to re-crush the cake materials 14 mixed in the powdery material 15 conveyed by the belt conveyor 12 into a powder form.

The crushing mechanism includes a first crushing plate 10 and a second crushing plate 6 which are disposed in parallel at a spaced position above a belt conveyor 12. A crushing gap for crushing the plate agglomerate 14 is formed between the first crushing plate 10 and the second crushing plate 6. The first crushing plate 10 is fixed to the upper part of the frame 13 in fig. 1 by means of fixing rods (not shown in the figures) which function to keep the first crushing plate 10 unchanged relative to the frame 13 and to maintain the stability of the first crushing plate 10 during the crushing process, the form of which can be chosen arbitrarily. The second breaker plate 6 is fixed to a reciprocating shaft 8 which is distributed horizontally and perpendicularly to the conveying direction of the belt conveyor 12. Two ends of the reciprocating shaft 8 are respectively installed on two linear bearings 9 which are fixed on the frame 13 and positioned at two sides of the belt conveyor 12 in a matching way. The outer circumference of the end of the reciprocating shaft 8 and the inner circumference of the axis bearing 9 are also provided with spline structures which are matched with each other so as to prevent the reciprocating shaft 8 from sliding. The lower end of the reciprocating shaft 8 is also in sliding contact with a rim of a cam 4 rotatably provided on the frame 13, and the cam 4 is driven to rotate by a motor 3 provided on the frame 13.

In the state shown in fig. 1, the non-convex portion of the cam 4 contacts the end portion of the reciprocating shaft 8, and the first crushing plate 10 and the second crushing plate 6 have the largest gap therebetween, and the crushing gap is the largest. As shown in fig. 2, when the cam 4 rotates 180 °, the convex portion of the cam 4 gradually pushes the reciprocating shaft 8 and the second crushing plate 6 toward the first crushing plate 10, so that the crushing gap is minimized, and the first crushing plate 10 and the second crushing plate 6 are close, thereby crushing the plate agglomerate 14 conveyed into the crushing gap. The technical effect of re-crushing the blocky plate caking material 14 into the powdery material 15 is achieved. After the state shown in fig. 2, as the cam 4 continues to rotate, the reciprocating shaft 8 and the second crushing plate 6 are pushed again toward the cam 4 by the elastic potential energy accumulated by the first return spring 7 until the state shown in fig. 1 is reached, which is ready for the next crushing. In order to optimize the extrusion fit between the cam 4 and the reciprocating shaft 8, the corresponding end part of the reciprocating shaft 8 is provided with the roller 5, and the roller 5 is in sliding fit with the rim of the cam 4, so that the phenomenon that the reciprocating shaft 8 is blocked in the rotating process of the cam 4 is avoided.

A guide mechanism is also provided in front of the crushing mechanism for guiding the plate agglomerate 14 in the direction of the crushing gap. The guide mechanism comprises two arc-shaped plates 11, the two arc-shaped plates 11 are distributed in a splayed shape on a rack 13, one arc-shaped plate 11 is fixed with the first crushing plate 10, one end of the other arc-shaped plate 11 is hinged with the second crushing plate 6, and the other end of the other arc-shaped plate is connected with a connecting column 1 fixed on the rack 13 through a second reset spring 2. As shown in fig. 1 and 2, the arc plate 11 located at the lower position can be always matched with the arc plate 11 located at the upper position under the action of the second return spring 2 in the process of moving along with the second crushing plate 6, so as to cover the whole width direction of the belt conveyor 12, thereby avoiding the leakage of the plate knot material 14 or generating the force of pushing the plate knot material 14 out of the belt conveyor 12.

As shown in fig. 3, the first crushing plate 10 and the second crushing plate 6 are both spaced from the conveying surface of the belt conveyor 12 and are not collided with the powder material 15 spread on the belt conveyor 12. Only after the agglomerates of the larger pieces mixed in the powdery material 15 enter the crushing gap, the agglomerates are crushed by the pressing action between the first crushing plate 10 and the second crushing plate 6.

The first crushing plate 10 and the second crushing plate 6 in the embodiment shown in fig. 3 are also provided with spring grooves 16 on opposite sides, by means of which spring grooves 16 part of the first return spring 7 can be accommodated, so that the first crushing plate 10 and the second crushing plate 6 are reliably close enough, so that the crushing gap is small enough, and thus the crushing of the finer plate cake 14 is possible.
