[0031] In order to make the content of the present invention more clearly understood, the present invention is further described in detail below based on specific implementation methods and in conjunction with the accompanying drawings.
[0032] Figure 1 This is a schematic diagram of the structure of a ton-bag unloading device for rejecting lithium hydroxide provided in an embodiment of the present application. The device includes a discharge box 1, a ton-bag inlet 2, a dust collection pipe 3, a discharge port 4, and a cutter 5. The rejecting ton-bag of lithium hydroxide is placed into the discharge box 1 through the ton-bag inlet 2. The rejecting ton-bag of lithium hydroxide is cut open by the cutter 5, and the rejecting lithium hydroxide is automatically discharged to the discharge port. During the discharge process, the dust collection pipe 3 continuously collects dust to prevent the rejecting lithium hydroxide dust from affecting the operator.
[0033] Specifically, the unloading box 1 is in the shape of a hollow cuboid, comprising an upper box and a lower box. Figure 2 The upper end, front side, rear side, and left side of the upper box body 1 are enclosed with 0.3 cm thick rectangular stainless steel plates. Two doors 8 are hingedly connected to the right side of the upper box body. When both doors 8 are closed simultaneously, the right side of the unloading box body 1 is closed. A rectangular ton bag inlet 2 with a side length of 50-60 cm is opened in the middle of the upper end of the upper box body. The lower end of the upper box body is designed to be open.
[0034] See also Figure 3 The lower box body of the discharge box body 1 includes four rectangular angle steels. The filter screen 7 is fixedly welded to the four angle steels. The filter screen 7 is made of stainless steel and has a thickness of 0.5 cm. The mesh holes of the filter screen 7 are circular holes with a diameter of 3.5 to 4.5 cm and a center spacing of 6 cm. The lower box body is supported by four round tube legs 12. Figure 1 After the upper box body and the lower box body of the unloading box body 1 are connected, a box body is formed with a ton bag feeding port 2 at the upper end, a filter screen 7 at the lower end and a closed side.
[0035] Preferably, an angular stainless steel frame 13 is further provided in the unloading box 1 to ensure the strength of the unloading box 1 .
[0036] The dust collection duct 3 is fixedly welded to the upper end surface of the discharge box 1 and is connected to the chamber inside the discharge box 1. When the door 8 of the discharge box 1 is closed, the air flow of the dust collection duct 3 must meet the requirement of maintaining negative pressure in the discharge box 1.
[0037] In this embodiment, the inner diameter of the dust collection pipe 3 is 8 to 12 cm, and the wall thickness is 0.4 cm.
[0038] See also Figure 4 The cutter 5 includes a handle and a trapezoidal cutter 5. In this embodiment, the handle is 120 to 140 cm long, the trapezoidal cutter 5 is 4 to 6 cm long, and the angle between the cutter 5 and the handle is 80 to 88 degrees. Figure 1A knife edge 6 is provided on the door 8 of the discharge box 1. The knife edge 6 allows the cutter 5 to freely enter and exit the internal chamber of the discharge box 1, thereby cutting the ton bag located in the discharge box 1. In this embodiment, the diameter of the knife edge 6 is 7.5 cm.
[0039] The upper end of the unloading box 1 is fixedly welded with a feeding bin 9. Figure 1 The feed bin 9 is in the shape of a hollow cone with open ends, and is invertedly installed on the discharge box 1. The upper bottom surface of the cone (the end surface with a smaller area) is fixedly connected to the upper end surface of the discharge box 1. The shape of the ton bag feed port 2 is the same as the shape of the upper bottom surface of the cone, both of which are rectangular, and the upper bottom surface of the cone is aligned with the ton bag feed port 2. The lower bottom surface of the cone (the end surface with a larger area) serves as the feed port of the feed bin 9. The unqualified lithium hydroxide ton bags enter the chamber inside the discharge box 1 through the feed bin 9.
[0040] In this embodiment, the angle between any side surface of the feeding bin 9 and the upper end surface of the discharge box 1 is 45°.
[0041] A discharge bin 10 is fixedly welded to the lower end of the discharge box 1. Figure 1 The discharge bin 10 is in the shape of a cone and is inverted and installed at the lower end of the discharge box 1. The lower bottom surface of the cone (the end surface with a larger area) is fixedly connected to the lower end surface of the discharge box 1. The shape of the lower bottom surface of the cone is the same as the shape of the lower end surface of the discharge box 1, and the lower bottom surface of the cone is aligned with the lower end surface of the discharge box 1. Two parallel angle steels are welded to the upper bottom surface of the cone (the end surface with a smaller area), and the thickness of the two parallel angle steel devices is 0.4 cm. A sealing plate 11 for opening or closing the discharge port 4 is installed at the discharge port 4. The sealing plate 11 is a stainless steel insert plate with a rectangular shape and a side length of 30 cm. The stainless steel insert plate can be opened and closed by sliding horizontally in the parallel angle steel.
[0042] In this embodiment, the angle between the side surface of the discharge bin 10 and the lower end surface of the discharge box body 1 is 40°.
[0043] When the above-mentioned unloading device for unqualified lithium hydroxide ton bags is in use, the unqualified lithium hydroxide ton bags are moved to the top of the feed bin 9 and enter the chamber inside the unloading box 1 through the feed bin 9 and the ton bag feed port 2. The dust collecting device connected to the dust collection pipe 3 is opened, and the box door 8 of the unloading box 1 is closed. A negative pressure is formed inside the unloading box 1, and the unqualified lithium hydroxide dust can be collected through the dust collection pipe 3. The cutter 5 extends from the blade 6 into the unloading box 1, and the tip of the cutter 5 vertically penetrates into the bottom of the ton bag to cut the unqualified lithium hydroxide ton bag. The unqualified lithium hydroxide is automatically discharged to the filter screen 7 and then to the discharge port. The sealing plate 11 is then pulled out to adjust the discharge amount of the unqualified lithium hydroxide.
[0044] Therefore, the technical solution of the present application can effectively isolate unqualified lithium hydroxide dust from contact with operators, and collect the generated dust, thereby reducing the workload of operators and improving work efficiency. Moreover, the collected powder can be re-dissolved to reduce waste and thus improve efficiency.
[0045] In addition to the above embodiments, the present invention may also have other implementation methods; any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
