Description

Technical Field

[0001] The utility model relates to the technical field of aerated concrete block raw material transportation, in particular to a material distribution device for aerated concrete block raw materials. Background Art

[0002] Aerated concrete blocks are a new type of green building material with thermal insulation, high strength, good earthquake resistance and excellent fire resistance. The production principle is: using gray sand, slag, fly ash and coal gangue as raw materials, adding cement to mix, and then adding aluminum powder as an aerating agent. After stirring, pouring, gasification, pre-curing, cutting, high-pressure steam curing and other steps, a porous silicate block is finally formed. In the production process of autoclaved fly ash aerated concrete blocks, it is generally necessary to arrange the production raw materials on the transportation device through the lower hopper, and then transport the materials to the stirring device set at a high position through the transportation device. In the existing distribution device, a small discharge port is generally opened under the lower hopper to control the discharge amount of the powder material, so that the powder material falling on the transportation device is within a controllable range, but this will cause uneven distribution, and the powder material discharge amount cannot be effectively controlled, and it is easy to cause the powder material to spill during the upward transportation process, which is not conducive to production.

DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 and Figure 2As shown, the embodiment of the utility model proposes a material distribution device for aerated concrete block raw materials, including a hopper support frame, a hopper 1 with a discharge port 101 at the bottom is arranged above the hopper support frame, the discharge port 101 is arranged as a rectangular portion, the long side of the rectangle is consistent with the movement direction of the conveyor belt 2, and the inner walls on both sides are provided with an inward-inclined structure 103 that is wide at the top and narrow at the bottom, which can play a buffering role for the falling of powder materials, and an inclined structure 104 is also arranged outside the discharge port 101. The motor 4 drives the conveyor roller 3 to rotate, and the conveyor roller 3 drives the conveyor belt 2 to move. The length of the end faces on both sides of the conveyor belt 2 exceeds the far end face of the inclined structure 104, so as to prevent the powder materials from spilling from the gap between the discharge port 101 and the conveyor belt 2. The contact surface of the inclined structure 104 and the conveyor belt is provided with a plurality of rollers, preferably embedded small rollers, to reduce the friction between the conveyor belt 2 and the hopper 1.

[0025] In another embodiment, a guide plate 7 is provided on the inwardly inclined structure 103 of the inner wall of the discharge port 101, and the guide plate 7 is preferably an inverted trapezoidal structure, and the trapezoidal oblique side is fixedly connected to the inwardly inclined structure 103 on the inner side of the discharge port 101, and the guide plate 7 is vertically arranged and evenly arranged along both sides of the conveyor belt 2, and the guide plate 7 is also rotated a certain angle in the movement direction of the conveyor belt 2, so that the guide plate 7 forms an acute angle with the long side of the discharge port 101, so that the guide plate 7 concentrates the falling powder to the middle of the conveyor belt 2 without blocking the powder from moving in the movement direction of the conveyor belt. The end face length of the guide plate 7 close to the conveyor belt 2 exceeds the end faces on both sides of the discharge port 101, so that the powder can be closer to the middle position of the conveyor belt 2 when distributing the material, and the occurrence of powder entering between the conveyor belt 2 and the inclined structure 104 can be effectively reduced.

[0026] like Figure 3As shown, the roller support frame 6 below the conveyor belt 2 is composed of an inclined roller 601, an inclined bracket 604 and a vertical bracket 605. The lower ends of the inclined bracket 604 are arranged at the two ends of the supporting beam 603 and are inclined inwardly at a certain angle. The lower ends of the vertical bracket 605 are vertically fixed near the middle of the supporting beam 603. The height of the inclined bracket 604 is greater than that of the vertical bracket 605, and the upper ends of the two are connected by a pin shaft, on which an inclined roller 601 is arranged. The inclined roller 601 can rotate under the drive of the conveyor belt 2. Due to the height difference between the inclined bracket 604 and the vertical bracket 605, the inclined roller 601 will tilt inwardly. The inclined rollers 601 on both sides of the supporting beam 603 will make the conveyor belt 2 present a bowl-shaped concave shape, which can be closely matched with the inclined structure 104 described in the lower hopper 1, so that the powder is finally concentrated in the middle of the conveyor belt 2. In another embodiment, adjacent vertical brackets 605 near the middle of the support beam 2 are connected by a pin shaft, and a straight roller 602 is also provided on the pin shaft. Preferably, the roller support frame 6 provided with the straight roller 602 and the roller support frame 6 not provided with the straight roller 602 can be fixed on the transport beam 5 at equal distances.

[0027] The detailed working process of this embodiment is as follows: after the aerated concrete block powder enters the lower hopper 1, it will move downward under the action of gravity, and after being buffered by the inward-inclined structure 103, it will fall on the moving conveyor belt 2 and keep moving in the same direction as the conveyor belt. By raising the inclined bracket of the roller support frame that supports the belt, the inclined rollers at both ends of the roller support frame will present a V-shaped structure. Under the action of the mutual cooperation with the inclined structure of the lower hopper, the conveyor belt sandwiched between the two will present a bowl-shaped concave shape, thereby well protecting the powder from being concentrated in the concave part of the conveyor belt. Under the action of the guide plate, the powder will further concentrate to the center of the conveyor belt. Finally, after adjusting the height of the powder through the discharge port and the baffle plate, it will be evenly distributed in the center of the conveyor belt and stably and smoothly transported to the next device.

[0028] like Figure 4As shown, according to another embodiment of the utility model, the material distribution device for aerated concrete block raw materials further includes a material blocking structure, wherein the material blocking structure includes a material blocking plate 9 and a chute box 8, the chute box 8 is arranged in pairs on the outer wall of the lower hopper 1 on one side of the discharge port 102, the lower end surface of the chute box 8 and the upper end surface of the discharge port 102 are in the same horizontal plane, the chute box 8 is provided with a chute 801 on the inner side, the distance between the opposite chute 801 is slightly larger than the width of the discharge port 102, the material blocking plate 9 has the same size as the chute box 8, so the two ends of the material blocking plate 9 can be inserted into the chute 801 of the chute box 8 and slide freely in the chute 801, the chute box 8 and The baffle plate 9 is also provided with a positioning structure for limiting the sliding of the baffle plate 9 in the slide groove 801, and the positioning structure includes a baffle plate slide groove 902, a square slider 901 and a strip limiting groove 802. The baffle plate slide groove 902 is arranged at the upper end corner of the baffle plate 9 and horizontally passes through the outer end face of the baffle plate 9. The square slider 901 is arranged in the baffle plate slide groove 902. The slider 901 can slide freely in the baffle plate slide groove 902. There are several strip limiting grooves 802, which horizontally pass through the free end face of the slide groove box 8 and are evenly distributed longitudinally. When the slider 901 enters the strip limiting groove 802 horizontally, the baffle plate 9 will not be able to move longitudinally in the slide groove 801. The detailed working process of this embodiment is as follows: when the baffle plate chute 902 coincides with the limit groove 802, the slider 901 can slide into the limit groove 802 horizontally. At this time, since the slider 901 is blocked by the limit groove 802 in the longitudinal direction, the baffle plate 9 can no longer slide longitudinally in the chute 801; when the slider 901 slides out of the limit groove 802, the baffle plate 9 can continue to slide in the chute 801. During the operation of the material distribution device, the slider 901 on the sliding baffle plate 9 is inserted into different limit grooves 802 of the chute 8, thereby realizing the function of controlling the discharge amount of the discharge port 102 by adjusting the position of the baffle plate 9. Based on the above further improvement, due to the different positions of the baffle plate 9 at the discharge port 102, the upper layer of powder that originally passed through the discharge port 102 will be blocked and restricted again, thereby achieving the effect of controlling the feeding rate and feeding amount.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
