Description

Technical Field

[0001] This utility model relates to the field of battery-related technology, and in particular to a feeding and conveying device. Background Technology

[0002] The main raw materials used to make the positive and negative electrodes of batteries are lithium cobalt oxide and graphite. These raw materials are in powder form and have a high density when stacked together. In order to make the positive or negative electrode of the battery, the powdered raw materials need to be mixed with other materials in a predetermined amount and at a predetermined time. In the past, the material was usually added manually to the mixing chamber at a predetermined time and in a predetermined quantity.

[0003] When the mixing chamber door is opened, the dust inside the mixing chamber will quickly disperse into the workshop. This dust is very harmful to the health of the workers who feed the materials and the workers in the workshop. Moreover, the production efficiency of manually feeding materials at fixed times and in fixed quantities is low, and the materials are also prone to accumulate in a certain position, resulting in uneven mixing in a short period of time.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] See Figure 1 and Figure 2 The present invention discloses a feeding and conveying device, comprising: a frame 100, wherein the frame 100 is provided with a feeding bin 200, the feeding bin 200 having an open cavity 210 and a door panel 220 for opening and closing the opening of the cavity 210, the cavity 210 being connected to an exhaust device 300, the exhaust device 300 having a filter element assembly 400 at its inlet or outlet end, the bottom of the cavity 210 having a discharge hopper 500 and a discharge pipe 600 connected to the discharge hopper 500, and the output end of the discharge pipe 600 being connected to a mixing chamber through a negative pressure adsorption device.

[0029] The material in the cavity 210 passes through the discharge hopper 500 and the discharge pipe 600 in sequence. Under the suction of the negative pressure adsorption device, it moves to the mixing chamber for use. When it is necessary to add material to the feeding hopper 200, there is a large amount of floating matter in the cavity 210. At this time, the exhaust device 300 is activated to reduce the air pressure in the cavity 210. The floating matter adheres to the filter element assembly 400 under the suction. At this time, opening the door panel 220 to add material will not cause dust problems, which is beneficial to human health. It also helps to improve the material conveying efficiency, alleviate the problem of material accumulation and jamming, and ultimately improve the mixing efficiency.

[0030] See Figure 2 In some embodiments of this utility model, the feeding bin 200 is provided with a partition 230 that divides the cavity 210 into a first chamber 211 and a second chamber 212. The first chamber 211 is directly connected to the material discharge pipe 600. The partition 230 is provided with a vent 231 that can connect the first chamber 211 and the second chamber 212. The filter element assembly 400 is provided at the vent 231 to prevent powder material from moving to the second chamber 212. The exhaust device 300 is a fan that connects the second chamber 212 to the outside. Understandably, after the material is basically conveyed into the second chamber 212, the fan starts working, the internal air pressure of the first chamber 211 decreases, thereby driving the gas in the second chamber 212 to flow towards the vent 231. A large amount of powdery material floats in the gas, and this powdery material is adsorbed onto the filter element assembly 400. At this time, the door panel 220 is opened, and the air in the second chamber 212 will not be turbid. After the material is manually added, the door panel 220 can be closed.

[0031] See Figure 2 and Figure 3In some embodiments of this utility model, the partition 230 is arranged horizontally, the second chamber 212 is located directly above the first chamber 211, the fan is located on the top wall of the feeding bin 200, and the filter element assembly 400 includes an upper end cover 410, a lower end cover 420 and a cylindrical filter element 430 connected between the upper end cover 410 and the lower end cover 420 located in the second chamber 212. The upper end cover 410 is located on the lower end face of the partition 230 and surrounds the vent 231. The upper end face of the partition 230 is provided with a mounting bracket 440 that passes downward through the vent 231 to connect the lower end cover 420. It should be noted that the second chamber 212 serves as the air intake chamber, and the required volume of the second chamber 212 is relatively small. The first chamber 211 occupies most of the volume of the cavity 210 to accommodate materials and place the filter element assembly 400. The filter element assembly 400 with the above structure is suspended and fixed on the partition plate 230 by the mounting bracket 440. The filter element assembly 400 adopts a cylindrical filter element 430 with a structure that is basically the same as that of the prior art, and the cost of use is low.

[0032] See Figure 3 In some embodiments of this utility model, in order to minimize the impact on the air intake at the vent 231 while achieving the suspension of the filter element assembly 400, the mounting bracket 440 includes a hanging rod 441. The lower end of the hanging rod 441 is connected to the lower end cover 420, and the upper end of the hanging rod 441 is connected to a mounting plate 442 mounted above the vent 231. The outer periphery of the mounting plate 442 is provided with multiple connecting ribs 443 connected to the upper end face of the partition plate 230. To prevent the cylindrical filter element 430 from being flattened by a large negative pressure suction, a support frame 444 extending along its length is provided in the middle of the hanging rod 441. The support frame 444 can abut against the inner peripheral wall of the cylindrical filter element 430, thereby ensuring the filtration effect of the cylindrical filter element 430.

[0033] In addition, the filter element assembly 400 is generally designed to be detachable for easy replacement, which will not be elaborated further here.

[0034] See Figure 1 and Figure 2 In some embodiments of this invention, the second chamber 212 is directly or indirectly connected to an inflation unit 700. The inflation unit 700 can input gas into the second chamber 212 to drive the powder material in the discharge hopper 500 through the discharge pipe 600 quickly. When the inflation unit 700 inputs gas into the second chamber 212, it can increase the internal air pressure of the second chamber 212, thereby assisting the negative pressure adsorption device in transferring the powder material to the mixing chamber.

[0035] In some embodiments of this utility model, the inflation unit 700 includes an air compressor and an air delivery pipe 710, with the outlet of the air delivery pipe 710 facing vertically downwards toward the air vent 231. It is conceivable that when the air compressor blows compressed air through the air delivery pipe 710 toward the air vent 231, some of the material adhering to the filter element assembly 400 can return to the discharge hopper 500, reducing material waste and extending the service life of the filter element assembly 400. This ingenious approach achieves multiple functions simultaneously.

[0036] See Figure 1 and Figure 3 In some embodiments of this utility model, two vents 231 and two filter element assemblies 400 are provided, and two corresponding air supply pipes 710 are provided. The two air supply pipes 710 are connected to a gas buffer tank 720, which is connected to the air compressor via an oil-gas separator 730. A valve 740 is provided on the bottom side of the gas buffer tank 720. It is understood that the first chamber 211 is typically a rectangular space, and the filter element assembly 400 is cylindrical. Arranging two filter element assemblies 400 is beneficial for improving space utilization and filtration effect. Specifically, the air compressor inputs high-pressure air into the gas buffer tank 720, and the oil-gas separator 730 separates the high-pressure air from the oil droplets in the air compressor, then outputs the air through the two air supply pipes 710. When dust or foreign matter is present in the gas buffer tank 720, the valve 740 can be opened for removal.

[0037] See Figure 1 and Figure 2 In some embodiments of this utility model, in order to improve the efficiency of material conveying and prevent materials from getting stuck in the discharge pipe 600, a vibration component 800 is provided on the side of the discharge pipe 600.

[0038] See Figure 1 and Figure 2 In some embodiments of this utility model, the upper part of the discharge pipe 600 and the lower part of the discharge hopper 500 are connected by multiple elastic suspension components 810 to create a height gap between the lower end of the discharge hopper 500 and the upper end of the discharge pipe 600. The multiple elastic suspension components 810 are evenly spaced around the outer periphery of the discharge pipe 600. The vibration component 800 includes at least two vibration motors spaced around the outer periphery of the discharge pipe 600. It is understood that when the vibration motors drive the discharge pipe 600 to vibrate, the elastic suspension components 810 will move slightly up and down, maintaining the height gap. The arrangement of the elastic suspension components 810 can prevent a large amount of vibration from the discharge pipe 600 from being transmitted to the discharge hopper 500, thus preventing the entire feeding and conveying device from experiencing significant vibration that could affect its safety and stability.

[0039] In some embodiments of this utility model, the material discharge pipe 600 is movably provided with a switch plate 910 capable of opening and closing the lower port of the material discharge pipe 600. The switch plate 910 is connected to a driver 920 that drives its operation. The driver 920, the fan, and the inflation unit 700 are all electrically connected to the control module. It should be noted that after the material is conveyed for a period of time, the material in the discharge hopper 500 and the material discharge pipe 600 is basically consumed. At this time, the control module drives the switch plate 910 to close, the fan to work to eliminate dust, and the user can open the door plate 220 to feed material. After the door plate 220 is closed, the control module drives the inflation unit 700 to work to accelerate the material conveying.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
