[0002] China is experiencing rapid development in the design of new energy and materials. Powder handling often results in floating dust pollution, which poses a significant threat to both workers and the environment. This is particularly true in the field of new energy battery manufacturing, where the tiny particles and complex composition of raw materials pose a greater risk. Therefore, addressing this floating dust pollution is crucial.

Furthermore, the relatively closed working environment poses a greater risk to human health. Furthermore, manual weighing methods are inefficient.

[0004] In view of this, this patent application is filed. Utility Model Content

[0011] In summary, the battery raw material quantitative loading device proposed in this application has the following advantages and beneficial effects:

[0030] Example 1, as Figures 1 to 5 As shown, the battery raw material quantitative loading device includes a frame 2, a silo 1 is arranged on the top of the frame 2, a distributor 4, a weighing mechanism 5 and a collection bin 6 are respectively installed in the middle of the frame 2, the bottom of the silo 1 is connected to the top of the distributor 4 through a discharge valve 3, the bottom of the distributor 4 is connected to at least two groups of weighing mechanisms 5, and a collection bin 6 is arranged at the bottom of each group of weighing mechanisms 5.

[0031] Among them, Figure 2 As shown, the silo 1 includes a silo body, an arch breaker 103 is provided inside the silo body for preventing the material from bridging and blocking the silo, an arch breaking motor 102 is installed on the silo body through an arch breaking motor base 101, and its output end is driven and connected to the arch breaker 103; at least one group of pneumatic vibration hammers 106 are installed through the side wall of the silo body for preventing the material from sticking to the wall, and a material level meter 104 and a respirator 105 are provided on the top of the silo body for detecting the height of the material in the silo;

[0032] like Figure 3As shown, the distributor 4 is connected to the weighing mechanism 5 at its bottom through a hose 401; a vibrator 402 and a switching cylinder 403 are provided on the side wall of the distributor 4 to prevent material blockage; the output end of the switching cylinder 403 is driven and connected to a switching valve plate (not shown in the figure) provided inside the distributor 4; the switching valve plate is driven and rotated by the switching cylinder 403, thereby realizing alternating feeding of materials to different weighing mechanisms 5;

[0033] like Figure 4 As shown, the weighing mechanism 5 is composed of a weighing bin 501 connected to the distributor 4, a feeding valve 502 and a feeding port 504 connected in sequence, and a weighing sensor 503 is provided at the bottom of the feeding valve 502;

[0034] like Figure 5 As shown, the collecting bin 6 includes a tray rack 604, a dust removal port 601 and a feeding port 602 are provided on the top of the tray rack 604, a slide rail and a push plate cylinder 603 are provided on the side of the tray rack 604, and the tray 605 is placed on the slide rail through a slider. The driving end of the push plate cylinder 603 can touch and push the tray 605 to move horizontally along the front and rear directions of the slide rail, and a collection box 606 for receiving materials spilled from the weighing mechanism 5 or the tray 605 is provided below the tray rack 604.

[0035] Based on the structural design of the above-mentioned battery raw material quantitative loading device, the following quantitative feeding and weighing operation process can be realized:

[0036] The material before drying is stored in silo 1;

[0037] When quantitative quantity is required, the material is discharged from the silo 1 by the discharge valve 3 and conveyed downward to the weighing mechanism 5; during the unloading process, the arch breaker 103 is started and causes the silo wall to vibrate to prevent the material from bridging or blocking in the silo 1, and at the same time, the pneumatic vibration hammer 106 can intermittently knock on the silo wall to prevent the material from adhering to the silo wall, and the material level meter 104 monitors the height position of the material accumulation in the silo in real time; during the feeding process to the weighing mechanism 5, the switching cylinder 403 on the distributor 4 drives the valve plate to switch, selectively realizing alternating unloading to different weighing mechanisms 5; wherein, the vibrator 402 prevents the material from blocking inside the distributor 4 by vibration, and the material is conveyed to the weighing bin 501 through the hose 401;

[0038] When the weighing sensor 503 detects that the material has reached the set value, the switching cylinder 403 drives the switching valve plate again to unload the material to another weighing mechanism 5;

[0039] The material is finally loaded onto the tray in the collection bin 6. When the material falls into the weighing bin 501 and reaches the set value, the push cylinder 603 drives the tray 605 to move to the specified position, and the feeding valve 502 starts feeding, thereby evenly laying the material on the tray 605. The above-mentioned loading operation is carried out alternately on different trays 605. When achieving quantitative loading of materials, the dust removal port 601 is connected to the external dust removal system, so that the entire feeding process is in a negative pressure environment to prevent dust from overflowing.

[0040] During the loading and feeding process, the material leaking from the tray 605 will be collected in the collection box 606 for further collection and use.
