The traditional method is to manually insert the mouth of the ton bag into the barrel. The ton bag will occupy the internal space of the barrel and affect the material discharge speed. In addition, since there is no sealing design between the ton bag and the barrel, when conveying powder materials, dust will float during the material discharge process, affecting the workshop environment and damaging human health. Especially for powder materials containing heavy metals such as the lithium battery industry, higher sealing requirements are required during the transportation process.

[0003] Therefore, it is necessary to design a barrel structure with good sealing performance, avoid material leakage and increase the material dropping speed. Utility Model Content

DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] Embodiment 1

[0026] like Figure 1 and Figure 2 As shown, a double-layer material receiving mechanism includes an inner cylinder 1, an outer cylinder 2 and a pressure cover 3. The inner cylinder 1 is fixed inside the outer cylinder 2. The outer diameter of the inner cylinder 1 is smaller than the inner diameter of the outer cylinder 2. The walls of the two are separated. The pressure cover 3 is located on the top of the inner cylinder 1 and the outer cylinder 2 and can move up and down. The outside of the pressure cover 3 is connected with a locking pressure plate 302. When the pressure cover 3 is closed, the pressure cover 3 clamps the bag mouth of the ton bag between the pressure cover 3 and the outer peripheral surface of the inner cylinder 1, and the locking pressure plate 302 is pressed on the upper end surface of the outer cylinder 2.

[0027] The outer cylinder 2 is connected to the lower-level material receiving equipment and plays a sealing and protective role. The inner cylinder 1 is used to connect to the bag mouth of the ton bag. The channel in the center is the material discharge channel. The bottom of the inner cylinder 1 preferably extends out of the outer cylinder 2, and the material discharge channel is extended into the interior of the lower-level material receiving equipment to avoid leakage at the entrance of the lower-level material receiving equipment. The pressure cap 3 can press the bag mouth to fix the ton bag and the entrance of the inner cylinder 1. The locking plate 302 can isolate the interior of the outer cylinder 2 from the external environment. Even if a small amount of material leaks into the gap between the inner cylinder 1 and the outer cylinder 2, it can enter the lower-level material receiving equipment from the bottom of the outer cylinder 2 and will not be exposed upward. When in use, first lift the pressure cap 3 upward, the bag mouth of the ton bag is sleeved outside the inner cylinder 1, and then the pressure cap 3 presses the bag mouth downward to complete the assembly, and you can start to discharge the material.

[0028] In traditional bag opening stations, the ton bag is directly put on the outside of the silo, tied manually, or stuffed inside the silo, which will cause a certain amount of dust leakage. The up and down movement of the pressure cap 3 can automatically press the bag opening. Compared with manual tightening, the pressure cap 3 can make the ton bag fit tightly with the outer peripheral surface of the inner tube 1 in the circumferential direction, with better sealing and higher work efficiency.

[0029] like Figure 2 As shown, the inner cylinder 1 and the outer cylinder 2 are both connected from top to bottom, and the bottom of the outer cylinder 2 is provided with a flange 4 connected to the lower-level material receiving equipment. The pressure cover 3 includes a pressure plate inner ring 301, and a locking pressure plate 302 is fixed to the outer circumferential surface of the pressure plate inner ring 301. The length of the pressure plate inner ring 301 is relatively long. When the bag mouth of the ton bag is clamped, the pressure plate inner ring 301 partially extends into the gap between the inner cylinder 1 and the outer cylinder 2, and the bag mouth of the ton bag is clamped between the pressure plate inner ring 301 and the inner cylinder 1, and the locking pressure plate 302 is pressed on the upper end surface of the outer cylinder 2.

[0030] The up and down movement of the gland 3 can be achieved by the lifting cylinder 5. Figure 2 As shown, a lifting cylinder 5 is provided outside the outer tube 2, and the telescopic rod of the lifting cylinder 5 is connected to the locking plate 302. The lifting cylinder 5 is preferably fixed on the flange 4. A cylinder mounting seat 6 can be provided above the flange 4, and the two ends of the lifting cylinder 5 are respectively fixed on the flange 4 and the cylinder mounting seat 6. It is preferred that two lifting cylinders 5 are symmetrically provided to ensure that the force on the circumferential surface of the gland 3 is balanced.

[0031] Embodiment 2

[0032] On the basis of the first embodiment, the gland 3 further comprises a sealing plate 304 fixed to the inner ring 301 of the plate, and the inner diameter of the sealing plate 304 is smaller than the outer diameter of the inner cylinder 1. Figure 3 As shown, when the gland 3 is closed, the sealing plate 304 abuts against the upper end surface of the inner tube 1. At this time, the inner ring 301 of the plate does not need to be close to the ton bag, and the ton bag can be pressed tightly by the sealing plate 304 at the top.

[0033] Embodiment 3

[0034] On the basis of the above embodiment, in order to further seal the gap between the outer cylinder 2 and the inner cylinder 1, the present embodiment is improved as follows: an inflatable sealing ring 303 is provided on the outer circumferential surface of the pressure plate inner ring 301 located below the locking pressure plate 302, and the inflatable sealing ring 303 fills the radial gap between the pressure plate inner ring 301 and the outer cylinder 2, thereby preventing the material from leaking upwards through the two structures of the inflatable sealing ring 303 and the locking pressure plate 302.

[0035] The fixing of the inner cylinder 1 and the outer cylinder 2 in the present invention can be selected from the following structures: Figure 1 As shown, the inner cylinder 1 is connected to the outer cylinder 2 via a plurality of reinforcing ribs 7 arranged in a circumferential array. The bottom of the outer cylinder 2 has a slot 201 for the reinforcing rib 7 to pass through. The reinforcing rib 7 passes through the slot 201 and is fixed to the flange 4 .

[0037] In this specification, the schematic representation of the terms does not necessarily refer to the same embodiment. Moreover, the specific features, structures, materials or characteristics described can be combined in any suitable manner in one or more embodiments.
