During the production process of batteries, production equipment often generates dust, which can seriously affect the quality of batteries and the stability of production equipment.

In battery production technology, dust removal devices are usually used to absorb dust generated by production equipment during the production process to reduce the dust content in the production equipment, thereby ensuring the production safety of the battery and maintaining the stable operation of the equipment. However, since the dust generated by battery production equipment during the production process is highly flammable and explosive, when the dust accumulates to a certain concentration in the dust removal device, it is very easy to cause risks such as fire and explosion, which can easily cause the dust removal device to explode and be damaged, making the dust removal device a major safety hazard during use, which is not conducive to battery production.

The specific structure of the dust sprayer 200 can be referred to the relevant technology, and will not be repeated here.

The powder sprayer 200 has a delivery pipe 210 , which is in communication with the air inlet pipe 10 , so that the powder sprayer 200 can provide inerting powder to the air inlet space 21 of the first processing chamber 20 through the air inlet pipe 10 .

The dust sprayer 200 provides inerting powder into the air intake pipe 10 so as to suppress the spontaneous combustion of dust after the inerting powder is sprayed into the air intake pipe 10. The inerting powder provided by the dust sprayer 200 may be of various types, such as sodium bicarbonate powder or calcium carbonate powder.

According to some embodiments of the present application, the embodiments of the present application provide a control method of a dust removal device 100, which is applicable to the dust removal device 100 of any of the above schemes, with reference to Figures 2, 3 and 4, and further to Figure 6, which is a flow chart of the control method of the dust removal device 100 provided in some embodiments of the present application, the control method of the dust removal device 100:

S100: Acquire state parameters in the air intake space 21, the state parameters including air pressure or dust concentration;

S200 : If the state parameter in the air intake space 21 is greater than or equal to the threshold, the air blowing mechanism 30 is controlled to operate for a first preset time period to blow air into the exhaust portion 23 .

Among them, in step S100, the state parameter in the air intake space 21 of the first processing chamber 20 is first obtained. The state parameter can be the air pressure in the air intake space 21 or the dust concentration in the air intake space 21. By way of example, in an embodiment of the present application, the state parameter is the air pressure in the air intake space 21, that is, step S100 is to first obtain the air pressure in the air intake space 21.

In step S200, when the state parameter in the intake space 21 is greater than or equal to the threshold, that is, when the air pressure in the intake space 21 is greater than or equal to the threshold, the blowing mechanism 30 can be started and blow air into the exhaust space 22 through the exhaust part 23 for the first preset time period. Conversely, if the air pressure in the intake space 21 is lower than the threshold, the dust removal device 100 operates normally.

Exemplarily, the first preset duration is 3 minutes. Of course, in other embodiments, the first preset duration may also be 1 minute, 2 minutes, 4 minutes, 5 minutes or 6 minutes, etc.

In the above control method, the state parameters representing the air pressure or dust concentration in the air intake space 21 of the first processing chamber 20 are first obtained to feedback the dust accumulation on the first filter element 40, so that when the state parameters in the air intake space 21 reach the threshold value, the blowing mechanism 30 can be controlled to operate the first A preset time is set to reversely blow air into the air intake space 21 through the exhaust part 23 to achieve reverse blowing and cleaning of the first filter element 40, thereby realizing automatic control of the blowing mechanism 30. While reducing manual participation, the first filter element 40 can be reverse blown and cleaned according to actual usage conditions, thereby effectively improving the safety of the dust removal device 100.

According to some embodiments of the present application, refer to Figures 2, 3 and 4, and further refer to Figure 7, which is a flow chart of a control method of a dust removal device 100 provided by some other embodiments of the present application. The dust removal device 100 also includes an air extraction mechanism 60, which is connected to the exhaust part 23. In step S200: If the state parameter in the air intake space 21 is greater than or equal to the threshold value, the air blowing mechanism 30 is controlled to run for a first preset time to blow air into the exhaust part 23, and the control method of the dust removal device 100 may also include:

S300: After the blowing mechanism 30 runs for a first preset time, the state parameters in the air intake space 21 are obtained again;

S400: If the state parameter in the air intake space 21 is not lower than the threshold, the air extraction mechanism 60 is controlled to stop operating.

Among them, in step S300, after the blowing mechanism 30 runs for a first preset time, the state parameters in the intake space 21 are obtained again, that is, after the blowing mechanism 30 blows air in reverse to the exhaust space 22 through the exhaust part 23 for a first preset time, the state parameters in the intake space 21 are obtained again, that is, the air pressure in the intake space 21 is obtained again.

In step S400, if the state parameter in the air intake space 21 is still greater than or equal to the threshold, that is, the air pressure in the air intake space 21 is still greater than or equal to the threshold, the exhaust mechanism 60 stops running to alleviate further risks. Conversely, if the air pressure in the air intake space 21 is lower than the threshold, the dust removal device 100 resumes normal operation.

In the above control method, after the blowing mechanism 30 blows air into the air intake space 21 through the exhaust part 23 for the first preset time period, the state parameters of the air intake space 21 of the first processing chamber 20 are obtained again. If the state parameters representing the air pressure or dust concentration in the air intake space 21 still have not dropped below the threshold, the exhaust mechanism 60 of the dust removal device 100 is stopped, thereby alleviating the safety hazard caused by the further increase of the air pressure in the air intake space 21, which is beneficial to improve the safety of the use of the dust removal device 100.

According to some embodiments of the present application, referring to Figures 2, 3 and 4, and further referring to Figure 8, Figure 8 is a flow chart of a control method of a dust removal device 100 provided in some embodiments of the present application. The dust removal device 100 also includes an air extraction mechanism 60, which is connected to the exhaust part 23. Step S100: After obtaining the state parameters in the air intake space 21, the control method of the dust removal device 100 may further include: if the state parameters in the air intake space 21 remain unchanged within a second preset time length, controlling the air extraction mechanism 60 to stop running.

Among them, if the state parameters in the air intake space 21 remain unchanged within the second preset time period, that is, the air pressure or dust concentration in the air intake space 21 of the first processing chamber 20 remains unchanged for the second preset time period, the exhaust mechanism 60 stops running to alleviate further risks.

In the embodiment of the present application, that is, the air pressure in the air intake space 21 remains unchanged for a second preset time period, and the air extraction mechanism 60 is controlled to stop running.

Exemplarily, the second preset duration is 3 minutes. Of course, in other embodiments, the second preset duration may also be 1 minute, 2 minutes, 4 minutes, 5 minutes or 6 minutes, etc.

In the above control method, after obtaining the state parameters characterizing the air pressure or dust concentration in the intake space 21, it is also possible to determine whether the state parameters remain unchanged within a second preset time period based on the state parameters in the intake space 21. If the state parameters remain unchanged, the dust removal device 100 may have damaged components, and thus, by stopping the exhaust mechanism 60, further safety hazards in the use of the dust removal device 100 can be alleviated.

According to some embodiments of the present application, the embodiments of the present application provide a control method of a dust removal device 1000, which is applicable to the dust removal device 1000 of any of the above schemes, with reference to Figures 1 and 5, and further to Figure 9, which is a flow chart of the control method of the dust removal device 1000 provided by some embodiments of the present application, the control method of the dust removal device 1000:

S1000: Obtaining the powder output of the powder sprayer 200 within a third preset time period;

S2000: If the powder output of the powder sprayer 200 is not within a preset range, adjust the powder output of the powder sprayer 200.

Among them, in step S1000, the amount of inerting powder provided by the duster 200 to the air intake space 21 within the third preset time period is first obtained. There can be multiple methods for obtaining the amount. For example, the amount of inerting powder sprayed into the air intake pipe 10 by the duster 200 can be detected to directly obtain the amount of inerting powder provided by the duster 200 to the air intake space 21 within the third preset time period. Or the weight change of the inerting powder in the duster 200 can be obtained to indirectly obtain the amount of inerting powder provided by the duster 200 to the air intake space 21 within the third preset time period.

Exemplarily, the third preset duration is 1 hour. Of course, in other embodiments, the third preset duration may also be 0.5 hours, 1.5 hours, 2 hours, 2.5 hours or 3 hours.

In step S2000, when the powder output of the duster 200 within the third preset time period is not within the preset range, that is, the powder output of the duster 200 within the third preset time period is greater than the preset range or less than the preset range, the controller 300 can reduce or increase the powder output of the duster 200 to adjust the powder output of the duster 200. Conversely, if the powder output of the duster 200 within the third preset time period is within the preset range, the dust removal equipment 1000 operates normally.

In the above control method, the amount of inerting powder provided by the powder sprayer 200 into the air intake space 21 of the first processing chamber 20 is fed back by obtaining the powder output of the powder sprayer 200 within the third preset time period, so that when the powder output of the powder sprayer 200 is not within the preset range, the amount of inerting powder provided by the powder sprayer 200 into the air intake space 21 can be adjusted. On the one hand, the phenomenon that the inerting powder is not effective in suppressing the spontaneous combustion of dust in the first processing chamber 20 due to insufficient inerting powder supply can be alleviated. On the other hand, the phenomenon that the inerting powder is wasted due to excessive inerting powder supply and the filtering pressure of the first filter element 40 is too high can be alleviated.

According to some embodiments of the present application, refer to FIG. 1 and FIG. 5, and further refer to FIG. 10, which is a flow chart of a control method of a dust removal device 1000 provided by some other embodiments of the present application.

In step S2000: if the powder output of the dust sprayer 200 is not within the preset range, after adjusting the powder output of the dust sprayer 200, the control method of the dust removal device 1000 may also include:

S3000: obtaining the powder output of the powder sprayer 200 within the third preset time period again;

S4000: If the powder output of the powder sprayer 200 is not within the preset range, the air extraction mechanism 60 is controlled to stop operating.

In step S3000, that is, after the controller 300 adjusts the powder output of the duster 200, the powder output of the duster 200 within the second third preset time period is obtained again.

In step S4000, if the powder output of the duster 200 within the second to third preset time periods is still not within the preset range, that is, the powder output of the duster 200 within the second to third preset time periods is still greater than the preset range or less than the preset range, the exhaust mechanism 60 stops running to alleviate further risks. Conversely, if the powder output of the duster 200 within the second to third preset time periods is within the preset range, the dust removal equipment 1000 resumes normal operation.

In the above control method, after adjusting the powder output of the powder sprayer 200, the adjusted powder output of the powder sprayer 200 within the third preset time period is obtained again. If the powder output of the powder sprayer 200 is still not within the preset range, the exhaust mechanism 60 of the dust removal device 100 is stopped, thereby alleviating the safety hazards caused by excessive or insufficient supply of inert powder, which is beneficial to improving the safety of the use of the dust removal equipment 1000.

In some embodiments, the powder output of the powder sprayer 200 within the third preset time length is obtained according to the weight change of the inert powder in the powder sprayer 200 within the third preset time length. That is, the powder output of the powder sprayer 200 within the third preset time length is obtained by recording the weight reduction of the inert powder in the powder sprayer 200 within the third preset time length. If the weight reduction of the inert powder is divided by the third preset time length, the powder spraying amount of the powder sprayer 200 per unit time is obtained.

In the above control method, the powder output of the powder sprayer 200 within the third preset time period is calculated and obtained by obtaining the weight change of the inert powder in the powder sprayer 200 within the third preset time period, which is easy to implement and operate and helps to reduce programming costs.
