Description

Technical Field

[0001] The utility model relates to the technical field of material conveying devices, in particular to a material discharge device for easy bridge powder materials. Background Art

[0002] Powders prone to bridging, including nano-ceramic powders (such as nano-alumina powder, nano-zirconia powder, etc.) and high specific surface area powders, are prone to bridging during storage and transportation. (Powder bridging is caused by excessive cohesion or adhesion of powdered materials, which leads to mutual adsorption between materials, thereby forming a pore structure that prevents the material from flowing freely.) This can easily lead to poor material discharge and affect production efficiency.

[0003] At present, there are three main devices for solving the problem of powder discharge that is prone to bridging: vibrating feeders, spiral feeders and pneumatic conveying systems. The vibrating feeder loosens the powder by vibration, so it has the disadvantages of high noise, high energy consumption and easy damage. The spiral feeder uses spiral blades to transport the powder to the discharge port, but this method has the disadvantages of limited conveying capacity, easy clogging and high maintenance difficulty. The pneumatic conveying system uses compressed air to transport the powder to the discharge port, but it is accompanied by disadvantages such as high energy consumption and serious dust pollution.

[0004] Therefore, a feeding device for easily bridging powder is needed to meet production needs. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-4 As shown, the utility model discloses a feeding device for easy-bridge powder material, which includes a driving mechanism, a feeding bin 1, a telescopic member 2 and an expansion and contraction member 3.

[0026] The lower silo 1 is used for containing powder.

[0027] The telescopic member 2 is provided with a first channel corresponding to the output port of the lower hopper 1 , wherein one end of the telescopic member 2 is connected to the output port of the lower hopper 1 , so that the powder in the lower hopper 1 is input into the first channel.

[0028] Preferably, the telescopic member 2 is made of a flexible rubber ring with elasticity, which can better cooperate with the containing and conveying of powder.

[0029] The expansion and contraction member 3 is provided with a second channel corresponding to the first channel and having a changeable space, wherein one end of the expansion and contraction member 3 is connected to the other end of the telescopic member 2, so that the powder in the first channel is transported to the second channel.

[0030] In this embodiment, the expansion and contraction member 3 includes a plurality of rigid baffles forming a second channel, wherein the driving mechanism includes at least one driving cylinder connected to at least one rigid baffle and used to drive at least one rigid baffle to move in a horizontal direction. That is, the number of driving cylinders is the same as the number of rigid baffles, so that the rigid baffle connected to the driving cylinder can be driven to move by the driving cylinder, thereby changing the space of the second channel.

[0031] Of course, in some embodiments, at least one driving cylinder can also drive at least one rigid baffle to move along other directions (such as an inclined direction).

[0032] Preferably, the driving cylinder includes a vibrating air cylinder, a vibrating hydraulic cylinder or other driving cylinders. It should be understood that the driving cylinder of this embodiment has a vibration function, so when the driving cylinder drives the rigid baffle to move, it also drives the rigid baffle to vibrate, so that the blanking effect is better.

[0033] It is worth noting that this embodiment does not limit the number of rigid baffles, as long as the number of rigid baffles forming the second channel is met, such as multiple rigid baffles including three rigid baffles, four rigid baffles, five rigid baffles, six rigid baffles and other rigid baffles, which depends on actual needs.

[0034] Furthermore, a flexible plate 35 is provided between two adjacent rigid baffles. It should be understood that the flexible plate 35 is elastic and is mainly used to facilitate the movement of the rigid baffles.

[0035] Preferably, the flexible plate 35 is made of rubber material, silicone material, fabric material or other elastic materials.

[0036] In this embodiment, the rigid baffle is in a rectangular plane shape, and the flexible plate 35 is in an arc shape. Of course, in other embodiments, the rigid baffle and the flexible plate 35 may also be in other shapes.

[0037] It can be understood that the second channel of the expansion and contraction member 3 is composed of multiple rigid baffles and flexible plates 35. When the driving cylinder drives the rigid baffles to move in the horizontal direction (or other directions, such as the inclined direction), due to the material structure of the flexible plates 35, the flexible plates 35 connected between the rigid baffles can expand the second channel. And because the material of the telescopic member 2 is a flexible rubber ring, the expansion and contraction member 3 will not cause the first channel and the second channel to be broken when expanding.

[0038] In a preferred embodiment, the multiple rigid baffles include a first rigid baffle 31, a second rigid baffle 32, a third rigid baffle 33 and a fourth rigid baffle 34, wherein flexible plates 35 are provided between the first rigid baffle 31 and the second rigid baffle 32, between the second rigid baffle 32 and the third rigid baffle 33, between the third rigid baffle 33 and the fourth rigid baffle 34, and between the fourth rigid baffle 34 and the first rigid baffle 31.

[0039] Furthermore, the driving mechanism includes a first driving cylinder 41 connected to the first rigid baffle 31 , a second driving cylinder 42 connected to the second rigid baffle 32 , a third driving cylinder 43 connected to the third rigid baffle 33 , and a fourth driving cylinder 44 connected to the fourth rigid baffle 34 .

[0040] Furthermore, the vertical cross-section of the first channel is in the shape of an isosceles trapezoid, and the horizontal cross-section of the first channel is in the shape of a rectangle, wherein the horizontal length and width of the output port of the lower hopper 1 are smaller than the horizontal length and width of the second channel, that is, the horizontal length and width of the output port of the lower hopper 1 are equal to the horizontal length and width of the top of the first channel, and the horizontal length and width of the top of the second channel are equal to the horizontal length and width of the bottom of the first channel. It should be understood that the horizontal diameter of the output port of the lower hopper 1 is smaller than the horizontal diameter of the second channel, so that when the expansion and contraction member 3 expands, the powder in the bridge at the output port of the lower hopper 1 falls directly from its original position due to the enlarged gap below, thereby destroying the original bridge phenomenon.

[0041] It is worth noting that in another special embodiment, the side wall of the output port of the lower silo 1 is made of a flexible material plate, so that the side wall of the output port of the lower silo 1 will also deform, that is, the diameter of the output port of the lower silo 1 will also change.

[0042] Preferably, the flexible material plate is made of rubber material or silicone material. It should be understood that the side wall is made of a flexible material plate made of rubber material or silicone material, which can make the telescopic movement of the telescopic member 2 and the expansion and contraction member 3 more convenient.

[0043] Furthermore, the unloading device for easily bridged powders also includes a conveying mechanism 5, which is disposed below the other end of the expansion and contraction member 3 and can transport the powders discharged from the unloading hopper 1 to a desired location. It should be understood that the conveying mechanism 5 can be implemented using products in the prior art, and its principles and structure are not detailed here.

[0044] Specific working principle:

[0045] When preparing to convey the powder, the powder can be poured into the lower hopper 1 first, and the powder can be discharged downward from the output port of the lower hopper 1. When the powder is conveyed downward in the lower hopper 1 and a bridging phenomenon occurs, the driving cylinder can be turned on at this time, and the driving cylinder can be allowed to move back and forth with the rigid baffle to expand or shrink the second channel of the expansion and contraction member 3. During the movement, the driving cylinder will also transmit the kinetic energy of vibration to the rigid baffle, so that the powder in the bridge at the output port of the lower hopper 1, the first channel and the second channel will be shaken off, thereby destroying the bridging phenomenon. The curved flexible plate 35 can allow the driving cylinder to drive the rigid baffle to move while ensuring the expansion of the second channel and utilizing the soft and tough properties of the flexible plate 35 material to avoid damage to the second channel. The conveying mechanism 5 can transport the powder to the required place, and this cycle is repeated, which greatly improves the unloading efficiency, while reducing energy consumption and dust pollution, and is easier to install and maintain.

[0046] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.
