Description

Technical Field

[0001] The utility model relates to the technical field of gypsum board manufacturing equipment, in particular to a pneumatic loosening mechanism for powder materials. Background Art

[0002] When powder materials are discharged from the silo, the powder particles squeeze each other and form pressure on the silo discharge section, which easily forms a material arch, affecting the material transportation efficiency of the silo. During the storage process, gypsum powder adheres to each other due to the humid environment, which reduces its fluidity during transportation and makes it more prone to blockage at the discharge port of the storage silo.

[0003] The solution to the blockage of the feed silo in the prior art is to use tools to knock or hit it manually or to install a vibrating device in the feed silo in advance. Although this process can solve part of the blockage problem, repeated vibration and knocking on the silo wall can easily cause the gap between the powder materials to decrease during the vibration process, making the powder particles become tight, thereby increasing the pressure on the silo wall and making the blockage problem more serious.

[0004] Therefore, it is necessary to provide a pneumatic loosening mechanism for powder materials to facilitate breaking the material arch formed during the material feeding process so that the powder materials can fall stably. Utility Model Content

[0008] Furthermore, the vibration component includes an elastic protrusion arranged on the flexible sheet; wherein the elastic protrusion protrudes out of the flexible sheet toward the outside of the air storage chamber; and the elastic protrusions are equidistantly arranged around the flexible sheet.

[0009] Furthermore, the flexible sheet is provided with a plurality of mounting holes which are equidistantly arranged around the mounting hole, and the vibration component comprises a spring sheet arranged in the mounting hole; wherein the spring sheet is connected to the porous plate through an elastic member; so that the spring sheet abuts against the four sides of the opening of the mounting hole.

[0010] Furthermore, one end of the spring sheet extends toward the mounting hole to form an outer edge; wherein ventilation gaps are equidistantly provided on the outer edge in the circumferential direction; and the ventilation gaps are provided along the axis of the spring sheet.

[0011] Furthermore, one end of the spring sheet extends toward the mounting hole to form an outer edge; wherein, ventilation holes are equidistantly arranged on the outer edge in the circumferential direction; and the axes of the ventilation holes are perpendicular to the section of the outer edge.

[0012] Furthermore, the vent hole is in a trumpet shape, wherein the large diameter end of the vent hole coincides with the inner wall surface of the outer edge, and the small diameter end of the vent hole protrudes from the outer wall surface of the outer edge.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, the utility model provides a pneumatic loosening mechanism for powder materials, comprising:

[0027] The gas storage chamber 1 has one end open to form a cavity sealed on all sides and at the bottom. A porous plate 11 is provided in the gas storage chamber 1. The porous plate 11 divides the gas storage chamber 1 into a gas storage chamber 12 and an actuating chamber 13. One side of the gas storage chamber 12 is connected to a gas source. A flexible sheet 131 is provided at the open end of the actuating chamber 13.

[0028] The outer edge of the flexible sheet 131 surrounds the open end of the air storage chamber 1 to form a seal for the action chamber 13;

[0029] A vibration component 2 is provided on the flexible sheet 131 , and the vibration component 2 is used to generate unidirectional vibration on the flexible sheet 131 by utilizing air pressure.

[0030] The utility model aims to use the air pressure change formed by the instantaneous pumping of compressed air into the air storage chamber 12 to produce deformation through the setting of the flexible sheet 131, so that the material arch formed by the powder material in the material bin is destroyed, the arch breaking efficiency of the powder bin is improved, and the powder material is transported more smoothly. Specifically, the pneumatic loosening mechanism provided by the utility model can replace the flexible sheet 131 as part of the side wall of the material bin ... of the pneumatic loosening mechanism provided by the flexible sheet 131, so that the material arch formed by the instantaneous pumping of the compressed air formed by the instantaneous pumping of the compressed air formed by the instantaneous pumping of the compressed air formed by the instantaneous pumping of the compressed air formed by the instantaneous pumping of the compressed air formed by the instantaneous pumping of the compressed air formed by the

[0031] In order to clearly illustrate the working mode of the flexible sheet 131 and the vibration component 2 in the present invention, a specific embodiment is provided below.

[0032] like Figure 1 As shown, in one embodiment of the present utility model, the vibration component 2 includes an elastic protrusion 21 provided on the flexible sheet 131;

[0033] The elastic protrusions 21 protrude from the flexible sheet 131 toward the outside of the air storage chamber 1 ; the elastic protrusions 21 are arranged around the flexible sheet 131 at equal intervals.

[0034] In this embodiment, the elastic protrusion 21 is provided to replace the flexible sheet 131 to deform when the air storage chamber 12 is inflated, and because the elastic protrusion 21 protrudes from the flexible sheet 131, the elastic protrusion 21 is deformed to a greater extent and is more likely to damage the arch foot. In actual use, the elastic protrusion 21 and the flexible sheet 131 are preferably made of flexible materials, and the elastic protrusion 21 is thinner than the flexible sheet 131, so that the elastic protrusion 21 is more likely to deform.

[0035] like Figure 2-3 As shown, in another embodiment provided by the present utility model, a plurality of mounting holes 132 equidistantly arranged around the flexible sheet 131 are provided, and the vibration component 2 includes a spring sheet 22 disposed in the mounting hole 132;

[0036] The spring piece 22 is connected to the porous plate 11 via the elastic member 221 , so that the spring piece 22 abuts against the periphery of the opening of the mounting hole 132 .

[0037] In this embodiment, by setting the spring piece 22 on the flexible sheet 131, an air flow channel that automatically opens and closes according to the air pressure is formed on the flexible sheet 131, so that the spring piece 22 is pushed up when the air pressure in the action chamber 13 increases, and the opening mounting hole 132 forms an air flow channel, and the material arch is pushed up by the instantaneous airflow and the pushing movement of the spring piece 22, thereby achieving the arch breaking effect and accelerating the falling of the material.

[0038] In order to prevent the powder material from falling from the gap between the spring sheet 22 and the flexible sheet 131 and being reversely sucked into the gas storage chamber 1 when the spring sheet 22 is opened, causing the porous plate 11 to be blocked, as shown in FIG. Figure 4 As shown, in another embodiment provided by the present invention based on the above embodiment, one end of the elastic sheet 22 extends toward the mounting hole 132 to form an outer edge 222;

[0039] Among them, ventilation gaps 223 are evenly spaced around the outer edge 222;

[0040] The ventilation gap 223 is formed along the axis of the spring piece 22 .

[0041] In this embodiment, by setting the outer edge 222, when the spring piece 22 is opened, a sealed space is formed between the outer edge 222 and the mounting hole 132, thereby preventing the powder from entering the air storage chamber 1, and by setting the ventilation gap 223 on the outer edge 222, the air flow can break the material arch through the ventilation gap 223.

[0042] In order to further solve the above problems, Figure 6-7 As shown, in another preferred embodiment provided by the present invention based on the above embodiment, one end of the elastic sheet 22 extends toward the mounting hole 132 to form an outer edge 222;

[0043] The outer edge 222 is provided with ventilation holes 224 at equal intervals in the circumferential direction; the axes of the ventilation holes 224 are perpendicular to the cross-section of the outer edge 222 .

[0044] More specifically, the vent hole 224 is in the shape of a bell mouth;

[0045] The large diameter end of the vent hole 224 coincides with the inner wall surface of the outer edge 222 , and the small diameter end of the vent hole 224 protrudes from the outer wall surface of the outer edge 222 .

[0046] In this embodiment, by setting the trumpet-shaped air vent 224, it is difficult for the material in the silo to fall into the air storage chamber 1 through the air vent 224 after the material arch is broken, thereby ensuring the cleanliness of the air storage chamber 1 and preventing the porous plate 11 from being poisoned. Moreover, the large-diameter end of the air vent 224 is set in the direction of the air flow, so that the flow velocity of the air flow increases after passing through the air vent 224, generating a greater air pressure while improving the air flow's ability to break the arch.

[0047] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
