Description

Technical Field

[0001] The utility model relates to the technical field of paper-faced gypsum board manufacturing equipment, and particularly relates to a structure of a bunker dividing wheel for blanking. Background Art

[0002] In the current production process of gypsum boards, for the storage and uniform transportation of powder materials, a conical bunker plus a dividing wheel is basically adopted for storage and blanking.

[0003] However, during the bunker blanking process, due to the differences in the specific surface area and crystal water content in the desulfurized gypsum powder feedstock, the fluidity of the powder materials in the bunker is either good or bad. For the powder materials with good fluidity, due to the poor sealing of the dividing plate of the dividing wheel in the bunker body, excessive blanking will occur, resulting in powder overflow or excessive powder in the subsequent equipment such as the conveying auger and bucket elevator, which easily causes the equipment to operate overload and trip due to overload.

[0026] As Figure 1 shown, the present utility model provides a blanking bin dividing wheel structure, including:

[0027] A blanking bin housing 10 having a cylindrical structure with both ends open, and the powder material forms a blanking flow flowing from one end to the other end by gravity inside it;

[0028] A power shaft 20 passing through the blanking bin housing 10 and axially connected to its side wall. The power shaft 20 is provided with dividing plates 21 arranged at equal circumferential intervals. The outer edge of the dividing plate 21 extends close to the inner wall of the blanking bin housing 10, so as to form a sealed space inside the blanking bin housing 10 through the dividing function of the dividing plate 21 for controlling the blanking flow;

[0029] Among them, a flexible sheet 22 is provided on the outer edge of the dividing plate 21 and abuts against the inner wall of the blanking bin housing 10. The flexible sheet 22 is detachably installed on the dividing plate 21, and a sealing strip 23 covering the connection gap between the flexible sheet 22 and the dividing plate 21 is provided to prevent the powder material from entering it.

[0030] A kind of blanking bin dividing wheel structure provided by the utility model fills the gap between the dividing plate 21 and the side wall of the blanking bin housing 10 by arranging a flexible sheet 22 on the periphery of the dividing plate 21, so as to improve the sealing effect of each blanking partition formed by the dividing plate 21 inside the blanking bin housing 10 and improve the accuracy of quantitative measurement during blanking. And further, a sealing strip 23 arranged between the dividing plate 21 and the flexible sheet 22 covers the gap generated between the flexible sheet 22 and the dividing plate 21 when the flexible sheet 22 deforms, avoiding the leakage of powder from this gap and making the quantitative standard during blanking relatively uncontrollable.

[0031] In the above embodiment, since the dividing plate 21 is in an intermittent rotational motion state, the flexible sheet 22 arranged thereon is prone to deformation during the process of contacting and rubbing against the side wall of the blanking bin housing 10, resulting in unstable connection between the flexible sheet 22 and the dividing plate 21.

[0032] To solve the above problems, as Figure 3 shown, in the preferred embodiment provided by the utility model based on the above embodiment, a positioning groove 211 is formed on the outer edge end wall of the dividing plate 21, and a positioning block 221 is arranged on the flexible sheet 22.

[0034] To further strengthen the stability of the connection between the flexible sheet 22 and the dividing plate 21, as Figure 4-5 shown, in the preferred embodiment provided by the utility model based on the above embodiment, a reinforcing column 212 is coaxially arranged in the positioning groove 211; wherein, a reinforcing groove 222 adapted to the reinforcing column 212 is coaxially arranged on the positioning block 221. When the positioning block 221 is embedded in the positioning groove 211, the reinforcing column 212 can be embedded in the reinforcing groove 222 to strengthen the fixing effect between the positioning block 221 and the positioning groove 211; the end of the reinforcing column 212 is 1 cm lower than the notch end of the positioning groove 211.

[0035] To further strengthen the stability of the connection between the reinforcing column 212 and the reinforcing groove 222, please continue to refer to Figure 6As shown, in the preferred embodiment provided by the present utility model based on the above embodiment, an annular limiting protrusion 213 is provided on the reinforcing column 212, and a limiting groove 223 adapted to the limiting protrusion 213 is provided on the reinforcing groove 222; wherein, the limiting protrusion 213 is provided in the middle of the reinforcing column 212, and the axial section of the limiting protrusion 213 is semi-elliptical.

[0036] In this embodiment, the reinforcing column 212 and the reinforcing groove 222 are connected to each other through the arrangement of the limiting protrusion 213 and the limiting groove 223. The limiting protrusion 213 is preferably made of a flexible material, such as rubber, so that it can be embedded in the reinforcing groove 222 to achieve a fixed connection.

[0037] In an embodiment provided by the present utility model, the sealing strip 23 includes a concave-shaped plate, and both ends of the sealing strip 23 are clamped in the dividing plate 21 and the flexible sheet 22; wherein, clamping grooves 24 are respectively provided on the flexible sheet 22 and the dividing plate 21, and the clamping grooves 24 are adapted to the edges of the sealing strip 23; the clamping grooves 24 penetrate through the dividing plate 21 and the flexible sheet 22 along the axial direction of the power shaft 20 respectively.

[0038] More specifically, the sealing strip 23 is fixed to the dividing plate 21 and the flexible sheet 22 through a fixing member 25; wherein, the fixing member 25 includes a bolt.

[0039] In this embodiment, by first clamping the sealing strip 23 on the dividing plate 21 and the flexible sheet 22 at the same time, and then fixing it to the dividing plate 21 and the flexible sheet 22 through the fixing member 25, the matching gap between the dividing plate 21 and the flexible sheet 22 can be stably sealed to prevent material leakage from this gap.
