[0001] The utility model belongs to the technical field of dredging equipment, and in particular relates to a dredging component, a feeding device and a stirring system. Background Art

[0002] The first step of the lithium battery slurry process is the powder process, which mainly uses gravity feeding to the planetary mixer. During the process of lithium battery main powder feeding to the planetary mixer, due to different material formulas and different feeding options, the material will remain in the feeding pipe.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Embodiment 1, in this embodiment, as Figure 1 As shown, this embodiment provides a dredging component, which includes: a cylinder 1, an air intake unit 2 and an air discharge unit 3; wherein an air storage chamber 101 is opened in the cylinder 1; the air intake unit 2 is connected to the air storage chamber 101, and the air discharge unit 3 is connected to the air storage chamber 101; the air intake unit 2 is suitable for inflating air into the air storage chamber 101; the air discharge unit 3 is suitable for opening the air storage chamber 101 so that the gas in the air storage chamber 101 forms an airflow and is blown out.

[0038] In this embodiment, the barrel 1 is installed with the blanking pipe 9, and the air intake unit 2 cooperates with the air release unit 3 to blow the blanking pipe 9, so as to better ensure that there is no residual accumulation of the main powder in the blanking pipe 9 and the reversing valve after the blanking is completed, thereby improving the blanking accuracy, reducing the blanking time and material waste, and using the air flow to apply pressure to the blanking pipe 9 to flush away the residue. It can automatically and quickly inflate, which is simple, convenient and fast. The strong air pressure can easily clear the blanking pipe 9 to prevent material bridging.

[0039] As an optional embodiment of the air intake unit 2, the air intake unit 2 includes: an air pump 201 and a first one-way valve 202; a first air inlet is opened on the cylinder 1, the first air inlet is connected to the air storage chamber 101, the first one-way valve 202 is installed at the first air inlet, and the air pump 201 is connected to the first one-way valve 202 through a first air intake pipe 203.

[0040] In order to realize automatic inflation of the air storage chamber 101, the air output by the air pump 201 opens the first one-way valve 202, and the air enters the air storage chamber 101, so that the air pressure in the air storage chamber 101 continues to increase. When the air pump 201 stops outputting air, the first one-way valve 202 is reset, and the air in the air storage chamber 101 cannot be discharged through the first one-way valve 202.

[0041] In order to provide a stable air pressure, an air filter 204 , a pressure reducing valve 205 and an oil mist collector 206 are arranged in the first air inlet pipe 203 .

[0042] The pressure reducing valve 205 can stabilize the air source and keep the air source in a constant state, which can reduce the damage to hardware such as valves or actuators caused by sudden changes in the air source pressure.

The oil mist device 206 can lubricate the moving parts of the machine body and can lubricate the parts that are inconvenient to add lubricating oil, thereby greatly extending the service life of the machine body.

[0043] As another optional embodiment of the air intake unit 2, the air intake unit 2 includes: an air supply pipe 207, an air supply handle 208, an air supply rod 209, an air supply piston 210 and a second one-way valve 211; a second air inlet is opened on the cylinder 1, the second air inlet is connected to the air storage chamber 101, the second one-way valve 211 is installed at the second air inlet, and the air supply pipe 207 is connected to the second one-way valve 211; an air supply port is opened on the air supply pipe 207, the air supply handle 208 is connected to the air supply piston 210 through the air supply rod 209, the air supply piston 210 is movably installed in the air supply pipe 207, the second one-way valve 211 is located on one side of the air supply port, and the air supply piston 210 is located on the other side of the air supply port.

The air replenishing piston 210 compresses the air in the air replenishing pipe 207, which can push open the second one-way valve 211, and the air enters the air storage chamber 101, so that the air pressure in the air storage chamber 101 continues to increase until the air replenishing handle 208 is stopped and the second one-way valve 211 is reset, and the air in the air storage chamber 101 cannot be discharged through the second one-way valve 211.

[0045] An air replenishing handle 208 is added so that when the amount of gas is insufficient, the gas storage chamber 101 can be replenished by manually pumping air.

[0046] In order to improve the structural strength, a base 102 is provided at the bottom of the cylinder 1 , and a deflation valve port 103 is provided on the base 102 ; the deflation unit 3 is movably arranged above the deflation valve port 103 .

[0047] Specifically, the thickness of the base 102 is greater than the thickness of the inner wall of the cylinder 1 , which is beneficial for the air in the air storage chamber 101 to be discharged from the air release valve port 103 after the air release valve port 103 is opened.

[0048] As an optional implementation of the deflation unit 3 , the deflation unit 3 includes: a deflation drive 301 and a deflation rod 302 ; the output portion of the deflation drive 301 is connected to the deflation rod 302 , and the end of the deflation rod 302 is arranged toward the deflation valve port 103 .

[0049] The deflation driving member 301 can pull the deflation rod 302 to move, so that the deflation rod 302 is close to or away from the deflation valve port 103 , thereby opening or blocking the deflation valve port 103 .

[0050] In order to improve the sealing performance when blocking the deflation valve port 103 , the deflation unit 3 further includes a flexible plug 303 ; the flexible plug 303 is arranged at the end of the deflation rod 302 , and the flexible plug 303 is arranged toward the deflation valve port 103 .

[0051] In order to adjust the blowing direction and angle, the dredging component further includes: a purge unit 4; the purge unit 4 is connected to the air release valve port 103 via a blowing pipe 401.

[0053] Specifically, the cylinder 1 and the blanking pipe 9 are installed obliquely, and the blanking pipe 9 connects the silo 8 and several execution devices. The execution device can be a mixer 10. By adjusting the number of air nozzles 402, the installation angle between the air nozzle 402 and the inner wall of the blanking pipe 9 and the blowing range of the air nozzle 402, the pipe and the valve body can be purged, and the angle between the air outlet direction of the air nozzle 402 and the material flow direction in the blanking pipe 9 is an acute angle.

[0054] In order to prevent the pressure in the air storage chamber 101 from being too high, a pressure-bearing pipe 5 is provided in the air storage chamber 101 .

[0055] Specifically, the pressure pipe 5 is a stainless steel pipe.

[0056] In order to monitor the pressure in the air storage chamber 101 , a pressure sensor 6 is provided in the air storage chamber 101 .

[0057] Specifically, each air nozzle 402 is installed to the lower side pipeline of the blanking pipe 9, and can be automatically and manually inflated. At the same time, the pressure sensor 6 can indicate the pressure. When the pressure warning value is reached, the pressure sensor stops inputting, and the purging is completed by instantaneous air pressure, which solves the problems of the existing powder material conveying pipeline, such as large conveying resistance, easy blockage, easy deterioration of materials, and difficult cleaning, and realizes automatic cleaning of the blanking pipe 9.

[0058] In order to ensure the safety of the equipment, a safety valve port 104 is further provided on the base 102 , and a safety pull rod 7 is movably provided above the safety valve port 104 .

[0061] Specifically, the rotary valve can control the amount of powder falling and effectively control the powder residue.

[0062] By installing the dredging component, it can be better ensured that there is no residual accumulation of main powder in the pipeline and valve body after the blanking is completed, the blanking accuracy is improved, the blanking time and material scrapping are reduced, and it has the function of simultaneously blowing the pipeline, valve body, valve plate, and blanking port of the mixer 10, and using the airflow to apply pressure to the pipeline to blow away the residual powder. It can automatically and quickly inflate, which is simple, convenient and fast. The strong air pressure can easily dredge the pipeline to prevent material bridging.

[0063] Embodiment 3, based on the above embodiment, Figure 1 to Figure 2 As shown, this embodiment provides a stirring system, which includes: a feeding device as provided in Example 2 and a plurality of stirrers 10; wherein the feeding device is connected to each stirrer 10.
