[0002] In arid regions and dusty regions such as coal mines, the most common cleaning equipment is a dry sweeper or a dust suction vehicle. The dry sweeper or the dust suction vehicle draws air from a suction nozzle through a fan, uses the negative pressure and high-speed airflow formed by the suction nozzle to suck the garbage on the ground into a garbage bin, and filters the dust and garbage in the air through a filter cartridge or a filter bag between the garbage bin and the fan. When the dust on the filter cartridge accumulates too much, the ventilation efficiency of the filter cartridge will be reduced, so the dust on the filter cartridge needs to be removed through reverse blowing, pulse dust removal, and beating.

[0003] At present, the most common pulse dust removal method on the market is to use a chassis air compressor or an air compressor driven by a secondary engine to provide high-pressure gas for the pulse of the filter cartridge in the garbage bin to complete pulse dust removal and reduce the problem of low filtering efficiency caused by dust blockage during use of the filter cartridge. However, due to the single source of high-pressure gas and the instability of the rotation speed of the air compressor due to other factors, the gas production is limited, the pulse dust removal frequency and time are not enough, and therefore the pulse dust removal effect is poor.

[0043] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0044] The most common pulse dedusting method on the market is to use a bottom plate air compressor or a secondary engine-driven air compressor to provide high-pressure gas for the filter cartridge in the garbage can to complete pulse dedusting and reduce the problem of low filtering efficiency caused by dust blockage during use. However, due to the single source of high-pressure gas and the unstable speed of the air compressor due to other factors, the gas production is limited, the pulse dedusting frequency and time are not enough, and therefore the pulse dedusting effect is poor.

[0045] Pulse dust removal is to release a large amount of high-pressure gas in the filter cartridge through the pulse valve for a short time (usually between 50ms-100ms), so that the filter cartridge expands, vibrates the outer wall of the filter cartridge, and thus peels off the dust on the filter cartridge. However, the gas generating device of the dust collection vehicle, dry sweeping vehicle and the like is on the chassis, and the filter cartridge, pulse valve and the like are on the garbage box, and the distance between the two is very far, and can only be transmitted through a small-aperture air pipe. Therefore, most of the gas released during each pulse dust removal comes from the gas bag connected to the pulse valve. At present, most of the gas bags used are fixed volume gas bags. Therefore, during the pulse process, the pressure of the high-pressure gas of the pulse gradually decreases over time. In actual use, it can be reduced by about 2-3bar within 50ms, thereby causing the pulse gas volume and pressure to decrease and the pulse effect to deteriorate.

[0046] The present application provides a new pulse dust removal system to solve the above problems. The high-pressure gas generated by the chassis gas supply device and the high-pressure gas generated by the upper-mounted gas supply device are combined, thereby increasing the amount of high-pressure gas during pulse, improving the pulse frequency and gas volume, and achieving better dust removal effect. In addition, by arranging a piston body in the gas bag to change the volume of the inner cavity, the instantaneous pressure change range of pulse dust removal is reduced, thereby ensuring the pressure stability during the entire pulse dust removal process, and improving the effect of pulse dust removal.

[0047] The pulse dust removal system for cleaning equipment and the cleaning equipment of the present application will be described below with reference to the accompanying drawings.

[0048] As shown in Figure 1 The present application provides a pulse dust removal system for cleaning equipment, wherein the pulse dust removal system for cleaning equipment comprises:

[0049] A pulse dust removal device 100 is used to interface with a filter device 500;

[0050] A chassis gas supply device 200 is connected to the pulse dust removal device 100;

[0051] An upper-mounted gas supply device 300 is connected to the pulse dust removal device 100;

[0052] A control device 700 is in communication connection with the chassis gas supply device 200, the upper-mounted gas supply device 300 and the pulse dust removal device, and is configured to:

[0053] The chassis gas supply device 200 and the upper-mounted gas supply device 300 are controlled to supply gas to the pulse dust removal device 100 in the case that the chassis gas supply device 200 meets the braking safety condition.

[0054] When the pulse dust removal system for cleaning equipment is used, since the pulse dust removal device 100, the chassis air supply device 200, the upper-mounted air supply device 300 and the control device 700 are included, the chassis air supply device 200 and the upper-mounted air supply device 300 are connected with the pulse dust removal device 100, and the control device 700 is configured to control the chassis air supply device 200 and the upper-mounted air supply device 300 to converge to supply air to the pulse dust removal device 100 in the case that the chassis air supply device 200 meets the braking safety condition, the air supply amount of the pulse dust removal device 100 is obviously and effectively increased by converging the chassis air supply device 200 and the upper-mounted air supply device 300 to supply air in the case of ensuring driving safety, and the increase of the air supply amount can further improve the frequency and times of pulse dust removal, so as to achieve the purpose of improving the pulse dust removal effect.

[0055] It should be particularly pointed out that the braking safety condition refers to the remaining air amount of the chassis air supply device 200 after supplying air to the pulse dust removal device 100 needs to at least meet the use amount of the chassis brake to ensure driving safety.

[0056] In the embodiment of the application, the pulse dust removal device 100 includes a gas package body 101 and a pulse valve 102 in communication connection with the control device 700, the gas package body 101 is formed with a chassis air inlet, an upper-mounted air inlet and an air outlet at intervals, the chassis air supply device 200 and the upper-mounted air supply device 300 are respectively and correspondingly butted with the chassis air inlet and the upper-mounted air inlet, one end of the pulse valve 102 is butted with the air outlet, and the other end is used for guiding the filter device 500. That is, the chassis air supply device 200 and the upper-mounted air supply device 300 can be controlled to converge to supply air to the gas package body 101, and after the air amount in the gas package body 101 reaches a certain value, the pulse valve 102 is controlled to intermittently cycle opening and closing to spray high-pressure air into the filter device 500 for pulse dust removal operation. Specifically, the gas package body 101 can be arranged at the top of a garbage can of the cleaning equipment.

[0057] Referring to Figure 1 and Figure 2 In the embodiment of the application, the pulse dust removal device 100 further includes a piston body 103 movably arranged in the inner cavity of the gas package body 101, and the inner cavity of the gas package body 101 is formed with a large cavity space 104 and a small cavity space 105 on the two sides of the piston body 103 correspondingly, the cross-sectional area A 大 of the large cavity space 104 is greater than the cross-sectional area A 小And the cross-sectional area ratio of the large cavity space 104 and the small cavity space 105 can be determined according to specific needs; the number of chassis air inlet is two, one of which is opened on the air bag body 101 corresponding to the small cavity space 105, and the air outlet, the upper air inlet and the other chassis air inlet are spaced apart on the air bag body 101 corresponding to the large cavity space 104, and the chassis air supply device 200 is respectively connected with the two chassis air inlets, so that the chassis air supply device 200 can supply air to the large cavity space 104 of the air bag body 101 together with the upper air supply device 300, so as to provide enough air for the pulse dust removal operation of the pulse valve 102, and at the same time, the small cavity space 105 of the air bag body 101 can also supply air, so that when a large amount of high-pressure gas is released in the large cavity space 104 due to the pulse dust removal operation, the high-pressure stripping in the small cavity space 105 will push the piston body 103 to move towards the large cavity space 104, reducing the volume of the large cavity space 104. When the volume of the large cavity space 104 becomes small, the pressure reduction rate in the space will slow down, so that the pulse pressure in the whole pulse dust removal process is more stable, and at the same time, through the volume change of the large cavity space 104 and the small cavity space 105 in the air bag body 101, the speed of the high-pressure gas generated by the chassis air supply device 200 into the air bag body 101 can also be accelerated.

[0058] At the same time, the first control valve 204 is arranged between the chassis air supply device 200 and the chassis air inlet corresponding to the large cavity space 104, and is in communication connection with the control device 700, and the control device 700 is further configured to:

[0059] When the chassis air supply device 200 meets the braking safety condition, the first control valve 204 is controlled to be opened, so that the chassis air supply device 200 and the upper air supply device 300 supply air to the large cavity space 104.

[0060] That is, the gas supply path of the chassis air supply device 200 can be switched by controlling the opening and closing of the first control valve 204, and the automation of path switching is realized. Specifically, when the chassis air supply device 200 meets the braking safety condition, the first control valve 204 is controlled to be opened, so that the chassis air supply device 200 and the small cavity space 105 of the air bag body 101 are both in communication with the large cavity space 104, and the chassis air supply space and the small cavity space 105 can both supply air to the large cavity space 104, and the upper air supply device 300 can also supply air to the large cavity space 104, so that the chassis air supply device 200 can supply air together with the upper air supply device 300 under the condition of ensuring driving safety. More specifically, the first control valve 204 can be an electromagnetic valve.

[0061] In the embodiment of the application, the pulse dust removal system for cleaning equipment further comprises a pressure detection device 400 for detecting the pressure in the large cavity space 104, and the pressure detection device 400 is in communication connection with the control device 700, and the control device 700 is further configured to:

[0062] In the case that the real-time pressure detected by the pressure detection device 400 is greater than the chassis safety pressure, the first control valve 204 is controlled to be opened, so that the chassis air supply device 200 and the upper-mounted air supply device 300 supply air to the large cavity space 104 in combination.

[0063] That is, the brake safety condition is that the real-time pressure detected by the pressure detection device 400 is greater than the chassis safety pressure. It should be particularly pointed out that the chassis safety pressure is a pressure determined according to the amount of air required for the chassis brake. Specifically, when the real-time pressure in the large cavity space 104 is greater than the chassis safety pressure, the chassis air supply device 200 can be switched to supply air to the large cavity space 104. Since the real-time pressure in the large cavity space 104 is greater than the chassis safety pressure, even if the chassis air supply device 200 supplies air to the large cavity space 104 afterwards, it can be ensured that the remaining amount of air of the chassis air supply device 200 is greater than the amount of air required for the chassis brake. In the prior art, when the chassis air source is used, the problem of brake safety of the chassis is not considered, so when the pulse dedusting frequency is too high, it may cause the chassis brake air source to be insufficient. In the present application, the pressure in the large cavity space 104 of the air bag body 101 is detected, and when the real-time pressure in the large cavity space 104 is higher than the chassis safety pressure, the chassis air source and the large cavity space 104 are connected, thereby ensuring the safety of the chassis brake system. More specifically, the pressure detection device 400 can be a pressure sensor. Of course, the present application is not limited thereto, and the pressure detection device 400 can also be directly arranged on the chassis air supply device 200, and the pressure detection device 400 detects the pressure of the air source of the chassis air supply device 200 to determine whether the amount of air is sufficient

[0064] In the embodiment of the present application, the control device 700 is further configured to:

[0065] In the case that the real-time pressure detected by the pressure detection device 400 is less than or equal to the chassis safety pressure, the first control valve 204 is controlled to be closed, so that the upper-mounted air supply device 300 supplies air to the large cavity space 104 alone.

[0066] Further, in the case that the real-time pressure detected by the pressure detection device 400 is less than or equal to the chassis safety pressure, the brake safety condition of the chassis air supply device 200 is not met, at this time, the first control valve 204 is controlled to be closed or continue to be closed, and the upper-mounted air supply device 300 is controlled to continuously supply air to the large cavity space 104 alone, until the real-time pressure of the large cavity space 104 detected by the pressure detection device 400 is greater than the chassis safety pressure, the first control valve 204 can be opened.

[0067] In the embodiment of the present application, a second control valve 304 in communication connection with the control device 700 is arranged between the upper-mounted air supply device 300 and the upper-mounted air inlet, like Figure 3As shown, the control device 700 is configured to perform the pulse dedusting method and sequentially perform the following steps:

[0068] Step 100, in the case that the real-time pressure detected by the pressure detection device 400 is greater than the chassis safety pressure, the first control valve 204 and the second control valve 304 are controlled to be opened for a first preset time, so that the chassis air supply device 200 and the upper-mounted air supply device 300 supply air to the large cavity space 104 in combination.

[0069] Specifically, step 100 is a large cavity air supply step, in the case that the brake safety condition of the chassis air supply device 200 is met, the first control valve 204 and the second control valve 304 are controlled to be opened for a first preset time, so that the small cavity space 105, the chassis air supply device 200 and the upper-mounted air supply device 300 supply air to the large cavity space 104 in combination for the first preset time.

[0070] Step 200, the first control valve 204 is controlled to be closed and the second control valve 304 is controlled to be continuously opened for a second preset time, so that the chassis air supply device 200 and the upper-mounted air supply device 300 supply air to the small cavity space 105 and the large cavity space 104, respectively, in one-to-one correspondence.

[0071] Further, step 200 is a two-cavity air supply step, after the first preset time of the large cavity air supply operation ends, the first control valve 204 is controlled to be closed and the second control valve 304 is controlled to be continuously opened for a second preset time, so that in the second preset time, the upper-mounted air supply device 300 continues to supply air to the large cavity space 104 and the chassis air supply device 200 switches to supply air to the small cavity space 105, thereby making P 小 *A 小 =P 大 *A 大 , in the formula, P 小 is the pressure in the small cavity space 105, A 小 is the cross-sectional area of the small cavity space 105, P 大 is the pressure in the large cavity space 104, and A 大 is the cross-sectional area of the large cavity space 104.

[0072] Step 300, the first control valve 204 and the second control valve 304 are controlled to be closed and the pulse valve 102 is controlled to be opened for a third preset time to perform the pulse dedusting operation.

[0073] Specifically, step 300 is a pulse dedusting step, in the third preset time, the first control valve 204 and the second control valve 304 are closed and the pulse valve 102 is opened, so that the air supply of the chassis air supply device 200 and the upper-mounted air supply device 300 to the large cavity space 104 is suspended during the pulse dedusting operation.

[0074] Assuming the pulse cycle time of the pulse dedusting system is T seconds, it can be divided into large cavity continuation gas time: T1, two cavity continuation gas time: T2, pulse time: T3, T=T1+T2+T3. Specifically, the large cavity continuation gas time T1 corresponds to the first preset time, the two cavity continuation gas time T2 corresponds to the second preset time, and the pulse time T3 corresponds to the third preset time.

[0075] In the large cavity continuation gas time T1, when the pressure detection device 400 detects that the real-time pressure in the large cavity space 104 is greater than the chassis safety pressure, the control device 700 controls the first control valve 204 to be powered on, and the first control valve 204 is communicated left and right. Because the pressures on both sides of the piston body 103 in the middle of the gas pocket 101 are consistent, but the cross-sectional area of the large cavity space 104 is larger, the piston body 103 will be quickly pushed towards the small cavity space 105, and the high-pressure gas from the chassis gas supply device 200 and the small cavity space 105 will quickly supplement into the large cavity space 104 of the gas pocket 101. As the piston body 103 moves towards the small cavity space 105, the volume of the large cavity space 104 increases, so that the pressure decreases, and the high-pressure gas from the chassis gas supply device 200 and the upper-mounted gas supply device 300 reaches the top of the gas pocket 101 more quickly.

[0076] In the two cavity continuation gas time T2, the control device 700 controls the first control valve 204 to be powered off and closed, and the upper-mounted gas supply device 300 continues to store gas in the large cavity space 104 of the gas pocket 101 through the second control valve 304, but the chassis power supply device supplies gas to the small cavity space 105 of the gas pocket 101, so that P small * A small = P large * A large.

[0077] In the pulse time T3, the pulse valve 102 is powered on to release a large amount of high-pressure gas in a short time, and the pressure in the large cavity space 104 decreases rapidly. At this time, the high-pressure gas in the small cavity space 105 will push the piston body 103 to move towards the large cavity space 104, reducing the volume of the large cavity space 104. When the volume becomes small, the pressure reduction rate of the space will slow down, so that the pulse pressure in the whole pulse process is more stable.

[0078] After the pulse time ends, the volume of the large cavity space 104 becomes smaller and the pressure is lower. At this time, if the gas source of the chassis is directly connected to the large cavity space 104, the pressure of the chassis gas source may decrease rapidly, causing the chassis pressure to be too low and causing a safety accident. Therefore, the upper-mounted gas supply device 300 needs to supply gas to the large cavity space 104 for a period of time, so that the real-time pressure in the large cavity space 104 is higher than the chassis safety pressure, and then the control device 700 controls the first control valve 204 to be powered on to open. The high-pressure gas in the small cavity space 105 can be supplemented into the large cavity space 104 again.

[0079] As Figure 2As shown, in the embodiment of the present application, the air pocket 101 comprises a large cavity part 106 and a small cavity part 107 which are in communication with the inner cavity, the piston body 103 comprises a large piston body 108, a small piston body 109 and a piston rod 110 connecting the large piston body 108 and the small piston body 109, the large piston body 108 is movably arranged in the large cavity space 104 formed by the large cavity part 106, and the small piston body 109 is movably arranged in the small cavity space 105 formed by the small cavity part 107. When the whole piston body 103 moves, the large piston body 108 is always located in the large cavity space 104, and the small piston body 109 is always located in the small cavity space 105, and the volume change of the large cavity space 104 and the small cavity space 105 is related to the length proportion of the piston rod 110 in the corresponding space. Of course, the present application is not limited to this, the piston body 103 can also be formed by directly connecting the large piston body 108 and the small piston body 109, and the piston rod 110 is not required to be arranged between the large piston body 108 and the small piston body 109.

[0080] Referring to Figure 1 In the embodiment of the present application, the chassis air supply device 200 comprises a chassis air compressor 201, a chassis air tank 202 and a chassis pressure reducing valve 203 which are arranged in sequence, and the pulse dust removal device 100 is connected with the chassis pressure reducing valve 203. The chassis air compressor 201 can output high-pressure gas under the driving of the chassis engine, and store the high-pressure gas into the chassis air tank 202, and the chassis pressure reducing valve 203 is arranged between the pulse dust removal device 100 and the chassis air tank 202 in order to ensure the stable work of the air pocket 101 in the pulse dust removal device 100.
