At present, when a lithium battery is charged and discharged for the first time, processes such as formation of a negative electrode SEI (solid electrolyte interface) film, deactivation of negative electrode material particles due to falling off, irreversible deposition of lithium metal and the like exist, active lithium of a positive electrode is consumed, and available energy of the battery is reduced. In order to compensate for the loss of active lithium during the first charge-discharge cycle of the battery, the battery is usually lithium-supplemented using a relevant lithium supplementation technique. For example, the lithium powder particles are spread on the surface of the electrode, however, in this way, the lithium-containing dust is easy to float to the air and pollute the air in the lithium supplementing process, and in addition, because the lithium metal is active in nature and is easy to react and burn in the high-temperature air and even explode, the generated dust needs to be collected by a dust collecting device in the lithium supplementing process.

The applicant finds that in the existing dust collecting equipment, after dust enters the dust collecting equipment, the dust automatically stacks up in the dust collecting equipment to be a cone, the piled dust structure is loose, the occupied space is large, the space utilization rate in the dust collecting equipment is low, and the dust is piled up fully easily, so that the dust collecting equipment needs to be cleaned manually frequently.

To solve or at least partially solve the above problems and other potential problems of the dust collecting devices of the prior art, the inventor of the present application proposed a dust collecting apparatus 1, and will hereinafter set forth specific solutions.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a dust collecting device 1 according to an embodiment of the present disclosure, and fig. 2 is a schematic structural diagram of the dust collecting device 1 according to the embodiment of the present disclosure after removing a flexible separating member 40. The dust collecting apparatus 1 includes a cleaner body 10, a push lever mechanism 30, and a flexible partition 40. The dust collector body 10 is provided with an inlet 11, a deposition chamber 12 and a storage chamber 13 are arranged in parallel in the horizontal direction in the dust collector body 10, a material collecting cylinder 20 is arranged in the storage chamber 13, and the deposition chamber 12 is provided with a first port 121 communicated with the inlet 11 and a second port 122 communicated with the storage chamber 13. The push rod mechanism 30 is disposed on a sidewall of the deposition chamber 12 opposite to the second opening 122, and a pushing portion 31 is disposed at an end of the push rod mechanism 30 close to the second opening 122, and the pushing portion 31 is configured to move in a direction close to or away from the second opening 122. A flexible spacer 40 is disposed within the deposition chamber 12 to separate the pusher mechanism 30 from dust within the deposition chamber 12. When the pressing portion 31 moves in the direction approaching the second port 122, the pressing portion 31 presses the flexible spacer 40 to press the dust of the deposition chamber 12 entering from the first port 121 into the material collecting tube 20 of the housing chamber 13.

The inlet 11 is an opening through which dust enters the cleaner body 10 from the outside. The deposition chamber 12 and the receiving chamber 13 may be arranged in parallel in front of and behind the cleaner body 10, or arranged in parallel from left to right, which is not limited in this embodiment.

The pusher mechanism 30 may include, but is not limited to, a mechanical pusher, an electric pusher, and the like, and the electric pusher may include, but is not limited to, a motor-driven telescopic rod, a hydraulic-driven telescopic rod, and the like. Preferably, the pusher mechanism is an electric pusher. The pressing portion 31 may be a pressing plate provided at one end of the pressing mechanism near the second port, but the pressing portion 31 may be a member having another shape having a pressing plane on the side facing the second port 122.

The flexible spacer 40 may be a spacer film made of plastic, non-woven fabric, glass fiber, or the like. The flexible isolating member 40 is used for separating the pushing mechanism 30 from dust in the deposition chamber 12, that is, the flexible isolating member 40 separates a dust accumulation space formed by communicating the moving space of the pushing mechanism 30 in the deposition chamber 12 with the first through port 121 and the second through port 122 into two parts which are independent of each other, so that the dust enters the deposition chamber 12 from the first through port 121 and is accumulated in the deposition chamber 12, the flexible isolating member 40 can isolate the accumulated dust in the deposition chamber 12 from the pushing mechanism 30, the problem that the movement resistance of the pushing mechanism 30 is increased due to the fact that the dust is attached to the pushing mechanism 30 is avoided, and meanwhile, the difficulty in cleaning the dust is reduced.

In the embodiment, the push rod mechanism 30 is arranged on a side wall of the deposition chamber 12 opposite to the second through hole 122, and the pushing part is arranged at one end close to the second through hole 122, so that the push rod mechanism 30 pushes the pushing part 31 to move towards the direction close to the second through hole 122, and then the dust accumulated in the deposition chamber 12 can be pushed into the material collecting barrel 20 of the accommodating chamber 13, after the pushing part 31 is compressed, the dust structure is changed from a loose state to a solid state, thereby not only cleaning the dust in the deposition chamber 12, but also reducing the occupied space of the dust in the accommodating chamber 13, greatly improving the utilization rate of the internal space of the dust collector body 10, periodically pushing the dust accumulated in the deposition chamber 12 into the accommodating chamber 13 through the pushing mechanism, reducing the frequency of manually cleaning the dust, and a user only needs to take out the material collecting barrel 20 in the accommodating chamber 13 and clean the dust in the material collecting barrel 20, the operation is simple and convenient.

In some examples, the flexible spacer 40 is an antistatic flame-retardant bag having a first opening 41 and a second opening 42 communicating with an inner space thereof, the first opening 41 being disposed in communication with the first through-hole 121, and the second opening 42 being disposed in communication with the second through-hole 122.

The antistatic flame-retardant bag is a bag-shaped structural member made of antistatic flame-retardant materials, and has the functions of antistatic and flame-retardant. When the dust gets into the deposition chamber 12 from first opening 121 in, thereby the dust will first opening 41 get into prevent in the fire-retardant bag of static, make the dust get into the deposition chamber 12 after, can directly pile up and prevent inside the fire-retardant bag of static, separate the dust in the deposition chamber 12 with push rod mechanism 30, make the dust can not produce too much contact with push rod mechanism 30, the dust absorption organism has reduced the production of static, also can play shielded effect to static each other simultaneously, when the dust is on fire, fire and push rod mechanism 30 keep apart can also be kept apart to fire by fire-retardant bag. Therefore, the anti-static flame-retardant bag of the embodiment of the application can isolate the dust in the deposition chamber 12 from the push rod mechanism 30, thereby avoiding the accident risk of dust burning caused by electric sparks generated by static electricity among the dust, the push rod mechanism 30 and the dust collector body 10.

In some embodiments, the edge portion of the first opening 41 and the edge portion of the first through opening 121, and the edge portion of the second opening 42 and the edge portion of the second through opening 122 may be fixed by magnetic attraction, such as a magnet, or may be fixed by a magnetic attraction, a hook and loop fastener, or may be fixed by a screw or a snap fastener, so that when the antistatic flame-retardant bag is worn or damaged, the antistatic flame-retardant bag may be removed and replaced.

In some embodiments, the dust collecting apparatus 1 further includes a dust inlet pipe 50 and a control assembly (not shown), one end of the dust inlet pipe 50 is disposed to communicate with the inlet 11, the other end of the dust inlet pipe 50 is a dust suction end, the dust suction end is provided with a temperature detector 51, a first control valve 52 is further disposed in the dust inlet pipe 50 between the temperature detector 51 and the inlet 11, and the first control valve 52 and the temperature detector 51 are respectively electrically connected to the control assembly. When the temperature detector 51 detects that the temperature of the dust at the dust suction end is greater than the first threshold value, the control assembly controls the first control valve 52 to close.

The dust inlet pipe 50 may be a tubular structural member with a hollow interior, and the dust inlet pipe 50 may be made of a hard plastic material or a metal material, which is specifically limited in the embodiment of the present application. Wherein, the end of the dust inlet pipe 50 communicated with the inlet 11 of the dust collector body 10 is a dust outlet end of the dust inlet pipe 50, and dust can enter the dust inlet pipe 50 through the dust outlet end, and then enter the dust collector body 10 from the inlet 11 of the dust collector body 10 through the dust outlet end of the dust inlet pipe 50.

The control component may be an upper computer and a controller, such as a single chip microcomputer and a plc controller, which are not specifically limited in this embodiment of the present application.

The temperature detector may include, but is not limited to, an infrared temperature sensor, a thermal resistance temperature sensor, and the like.

The first control valve may be a butterfly valve, ball valve, or other form of control valve, such as a sleeve-type control valve.

The first threshold value may be set according to a temperature at which dust inside the dust collector body 10 starts to burn in a specific usage scenario, that is, the first threshold value may be set as an initial temperature value at which dust in the dust collector body 10 starts to burn.

Because the dust contains lithium powder, the lithium metal has active property, and is easy to react and combust in high-temperature air and even explode. Therefore, in use, when the temperature detector 51 detects that the temperature of the dust is greater than the first threshold, that is, the temperature detector 51 detects that the dust at the dust suction end is high-temperature dust, the control assembly controls the first control valve 52 to close, so as to prevent the high-temperature dust from entering the dust suction machine body 10 from the dust inlet pipeline 50; when the temperature detector 51 detects that the temperature of the dust is lower than the first threshold value, that is, the temperature detector 51 detects that the dust at the dust suction end is non-high temperature dust, the first control valve 52 is kept in an open state, and the control component does not perform any operation on the first control valve 52.

The present embodiment is provided with a temperature detector 51 at the dust suction end of the dust inlet pipe 50, so that the control component controls the opening and closing of the first control valve 52 according to the temperature of the dust detected by the temperature detector 51 at the dust suction end, thereby preventing the risk of burning and even explosion of excessive high-temperature dust entering the dust collector body 10.

In some specific embodiments, the length s of the conduit between the first control valve 52 and the temperature detector 51 satisfies the following relationship: s > vt; where v and t are both positive numbers, v is the flow rate of the dust in the dust intake pipe 50, and t is the response time period from when the temperature detector 51 detects that the temperature of the dust at the dust suction end is greater than the first threshold value to when the first control valve 52 is fully closed.

The temperature detector 51 starts to detect the dust temperature, the detected dust temperature is sent to the control assembly in an electric signal mode, the control assembly converts the electric signal into a corresponding temperature value, compares and judges the temperature value with a first threshold value, and determines whether to control the first control valve 52 to be closed according to a judgment result, a certain time is consumed in the process, and meanwhile, certain reaction time is needed when electric components such as the temperature detector 51, the control assembly and the first control valve 52 work. If the distance of the dust flowing in the dust inlet duct 50 is longer than the duct length s between the first control valve 52 and the temperature detector 51 during the response period from the time when the temperature detector 51 detects the temperature of the dust to the time when the first control valve 52 is completely closed, the dust passes through the first control valve 52 before the first control valve 52 is completely closed, and the first control valve 52 cannot function to prevent the high-temperature dust from entering the cleaner body 10.

The present embodiment can effectively prevent the high temperature dust detected by the temperature detector 51 from entering the cleaner body 10 by setting the duct length s between the first control valve 52 and the temperature detector 51 to be longer than the distance that the dust travels in the dust intake duct 50 during the response time period, so that the first control valve 52 is completely closed when the high temperature dust reaches the first control valve 52.

In some embodiments, the first control valve 52 may be a butterfly valve. The butterfly valve is simple in structure, large in valve caliber, high in response speed when being opened and closed, suitable for application scenes of achieving automatic frequent operation control, capable of further reducing the response time and meanwhile reducing the total length of the dust inlet pipeline 50.

In some embodiments, a duct filter 53 is further provided between the inlet 11 and the first control valve 52, and the duct filter 53 is used to filter and passivate dust entering the dust inlet duct 50.

The pipe filter 53 may be a filter with silicone oil or other passivating agent solution therein. As an example, taking a filter containing silicone oil as an example, when the dust passes through the pipe filter 53, the silicone oil may form an oil film on the surface of active dust such as lithium powder, so that the lithium powder particles cannot react with other substances, thereby performing a passivation function, and the pipe filter 53 may also be used to filter out some dust with large particle size.

The pipeline filter 53 is arranged between the inlet 11 and the first control valve 52, so that some dust with large particle size can be filtered out, and meanwhile, the dust with strong activity is passivated, so that the risk that too much dust with strong activity is accumulated in the dust suction machine body 10 and the dust is combusted or even exploded due to chemical reaction in the air is avoided.

In some embodiments, the duct filter 53 is detachably connected between the dust inlet duct 50 and the inlet 11 of the dust collection body 10.

Specifically, the feed inlet of the duct filter 53 and the dust outlet end of the dust inlet duct 50, and the discharge outlet of the duct filter 53 and the inlet 11 of the dust collector body 10 are respectively fixed by screwing through flanges. Of course, in other embodiments, the duct filter 53 can be fixed between the inlet 11 of the cleaner body 10 and the dust outlet end of the dust inlet duct 50 by a flange or other connecting members in a snap-fit manner.

In the embodiment, the pipe filter 53 is detachably installed between the dust outlet end of the dust inlet pipe 50 and the inlet 11 of the dust collector body 10, so that when the pipe filter 53 is blocked, the pipe filter 53 can be detached for replacement or cleaning, maintenance is convenient, and the use cost is reduced.

In some embodiments, the cleaning machine body 10 further has a clean room 14 and an exhaust room 15, the clean room 14 and the deposition room 12 are sequentially communicated from top to bottom, and the clean room 14 is communicated with the inlet 11 and the first port 121, respectively. A filter cartridge 16 is also provided in the clean room 14 in communication with the exhaust chamber 15. A blower 17 and a back-blowing assembly 18 which are electrically connected with the control assembly are also arranged in the exhaust chamber 15, the blower 17 is used for guiding the air in the purifying chamber 14 to the exhaust chamber 15 and discharging the air to the outside of the dust collector body 10, and the back-blowing assembly 18 is used for removing the dust attached to the outer surface of the filter cartridge 16.

Wherein the exhaust chamber 15 is communicated with the outside atmosphere, and the exhaust chamber 15 and the deposition chamber 12 are respectively communicated with the inlet 11 through the purge chamber 14. The filter cartridge 16 serves to filter dust contained in the air in the clean room 14 so that the fan 17 discharges the filtered air from the exhaust chamber 15 to the outside. The blowback assembly 18 includes a gas tank and a blowing nozzle connected to the gas tank, the blowing nozzle is disposed in the filter cartridge 16, and the blowback assembly 18 may be of an existing structure and will not be described in detail herein.

When the fan 17 works, the dust inlet pipe 50, the inlet 11, the purification chamber 14, and the exhaust chamber 15 are sequentially communicated to form an air flow channel of air, and the flow rate of the air in the dust inlet pipe 50 is the flow rate of the dust in the dust inlet pipe 50, so that when the pipe length from the first control valve 52 to the temperature detector 51 is designed, the flow rate of the air in the dust inlet pipe 50 when the fan 17 works can be used as the flow rate of the dust. In the process of flowing the air from the purifying chamber 14 to the exhaust chamber 15, the dust in the air is blocked on the outer surface by the filter cartridge 16, and part of the dust falls and accumulates in the deposition chamber 12, so that the dust in the air to be exhausted to the external atmosphere environment in the dust collector body 10 is filtered, and the external environment is prevented from being polluted by the dust; when the dust attached to the surface of the filter cartridge 16 is more and more, the pressure difference between the exhaust chamber 15 and the purification chamber 14 is increased, and when the pressure difference reaches a preset value, the control assembly controls the blowing nozzle of the blowback assembly 18 to be opened to perform blowing operation, so that the dust attached to the surface of the filter cartridge 16 falls into the deposition chamber 12, thereby achieving the purpose of removing the dust attached to the outer surface of the filter cartridge 16, reducing exhaust resistance and reducing power consumption of the fan.

This application embodiment sets up through the intercommunication department with exhaust chamber 15 in clean room 14 and strains a section of thick bamboo 16 to the outside air of dust catcher organism 10 exhaust through straining a section of thick bamboo 16 and filtering the dust avoids the dust to cause the pollution to the external environment, can clear up automatically simultaneously through setting up blowback subassembly 18 and attach to straining a section of thick bamboo 16 surface dust, reduces and reduces the exhaust resistance, reduces fan 17's consumption.

In some embodiments, the cleaning chamber 14 may be funnel-shaped so that dust falling from the filter cartridge 16 can slide more smoothly into the deposition chamber 12 through the slope of the inner wall of the funnel-shaped cleaning chamber 14.
