Referring to fig. 1, an embodiment of the present invention provides a filtering apparatus, including: a housing 11 having an inner cavity, and an air inlet 111 and an air outlet connected to the inner cavity; the filtering component 13 is fixedly arranged in the inner cavity and divides the inner cavity into a filtering chamber and a clean room, the air inlet 111 is communicated with the filtering chamber, and the air outlet is communicated with the clean room; the ash cleaning component 12 is movably arranged in the filtering chamber; the control assembly comprises a pressure difference detection unit and a driving unit, the pressure difference detection unit is used for detecting the pressure difference at two sides of the filtering assembly 13, and the driving unit is in transmission connection with the ash removal assembly 12; when the magnitude of the pressure difference reaches the pressure difference threshold value, the ash cleaning component 12 moves from the initial position to the cleaning position under the driving of the driving unit so as to clean the filtering component 13.
Wherein, the deashing subassembly 12 can clean filter component 13 on the clean position, and when deashing subassembly 12 was in initial position, can not clean filter component 13.
In practical use, the gas enters the filter chamber through the air inlet 111, enters the clean room after being filtered by the filter assembly 13, and is discharged out of the filter device through the air outlet to obtain clean gas; along with the continuous generation of clean gas, dust accumulated on the filter assembly 13 is more and more, the pressure difference between the air inlet side and the air outlet side of the filter assembly 13 is larger and larger, and the resistance of the gas in the filter chamber entering the clean room through the filter assembly is larger and larger; when the pressure difference between the two sides of the filtering component 13 reaches the pressure difference threshold value, it is described that much dust is accumulated on the filtering component 13, the filtering capacity of the filtering component 13 is greatly reduced, the ash removal component 12 needs to be started to perform ash removal treatment on the filtering component 13, at this time, the driving unit drives the ash removal component 12 to move to the cleaning position, and when the ash removal component 12 is located at the cleaning position, automatic cleaning treatment can be performed on the dust on the filtering component 13.
Compared with the prior art, the dust on the filtering component 13 can be automatically cleaned, the filtering component 13 can be used for multiple times, manual replacement or cleaning is not needed, and the equipment maintenance cost can be reduced; meanwhile, the dust can be removed in time according to the actual operation condition of the filtering device, and the problem of unstable equipment operation caused by untimely dust removal can be avoided.
Optionally, the pressure difference threshold corresponds to a pressure difference value when the resistance of the filter device is twice the initial resistance, and at this time, when the resistance of the filter device is twice the initial resistance and the ash removal is started, the economic benefit is considered, and the machine is prevented from being operated excessively.
In one embodiment, the filter chamber has opposing first and second walls, both extending in the direction of air intake of the filter assembly 13; the ash removal component 12 has a fixed end and a movable end, the fixed end of the ash removal component 12 is connected to the first wall surface, and the movable end of the ash removal component 12 is configured to be close to or far away from the second wall surface under the driving of the driving unit.
When the movable end of the ash removal component 12 is close to the second wall surface, the ash removal component 12 is located at the cleaning position, the ash removal component 12 faces the filtering component 13, and the air duct between the filtering component 13 and the air inlet 111 can be isolated or partially isolated, so as to perform ash removal treatment on the filtering component 13; when the movable end of the ash removal assembly 12 is far away from the second wall surface, and the ash removal assembly 12 is located at the initial position, the ash removal assembly 12 partially or completely isolates the air channel between the filter assembly 13 and the air inlet 111, so as to reduce the wind resistance to the air flow.
In actual use, the first wall surface and the second wall surface can be the top surface and the bottom surface of the housing 11, respectively, so that the fixed end of the ash removal component 12 is connected to the top surface, the weight of the ash removal component 12 can control the movement of the ash removal component 12, and the driving power consumption can be reduced.
In an alternative embodiment, the fixed end of the ash removal assembly 12 is hinged to the first wall surface, and the movable end of the ash removal assembly 12 is driven by the driving unit to rotate relative to the first wall surface. When the movable end of the ash removal component 12 rotates towards the first wall surface, the ash removal component 12 moves away from the second wall surface and moves from the cleaning position to the initial position; when the movable end of the ash removal assembly 12 is rotated toward the second wall surface, the ash removal assembly 12 is rotated from the initial position to the cleaning position. So, can enough realize the switching of deashing subassembly 12 stations through rotating deashing subassembly 12, can also accomodate deashing subassembly 12 on first wall simultaneously, avoid the structure of accomodating of special design accomodate deashing subassembly 12, can also simplify the structure of filter chamber.
Optionally, an articulated shaft for articulating the first wall surface is fixedly arranged at the fixed end of the ash removal component 12, and the articulated shaft rotates relative to the first wall surface at the movable end of the ash removal component 12 under the driving of the driving unit so as to support the movable end of the ash removal component 12 to rotate.
Further, when the ash removal assembly 12 is located at the initial position, the fixed end of the ash removal assembly 12 is disposed closer to the filter assembly 13 than the movable end of the ash removal assembly 12. So, the expansion end of deashing subassembly 12 is close to filter component 13 towards the orientation when moving towards the second wall, is favorable to drawing close deashing subassembly 12 and filter component 13's distance, improves the deashing effect.
Furthermore, a first connecting portion 121 is disposed on the movable end of the ash removing assembly 12, a second connecting portion 122 is disposed on the second wall surface, and the first connecting portion 121 and the second connecting portion 122 are detachably connected. Thus, when the ash removal assembly 12 moves to the cleaning position, the connection between the first connection portion 121 at the movable end of the ash removal assembly 12 and the second connection portion 122 on the second wall surface is helpful to improve the instability of the ash removal assembly 12 due to the overlarge air volume of the air inlet 111 during ash removal.
Optionally, one of the first connection portion 121 and the second connection portion 122 is a snap, and the other of the first connection portion 121 and the second connection portion 122 is a bayonet, and the snap is in clearance fit with the bayonet. When the movable end of the ash removal component 12 moves towards the cleaning position, the buckle moves into the bayonet along with the ash removal component 12, and when the movable end of the ash removal component 12 moves towards the initial position, the buckle is separated from the bayonet.
Alternatively, the first connecting portion 121 and the second connecting portion 122 may also be magnetic components, such as a magnetic strip, a magnetic block, and the like, and at this time, the first connecting portion 121 and the second connecting portion 122 may be magnetically attached.
Furthermore, an electromagnetic valve 15 is arranged on the first wall surface, a magnetic part is arranged on the movable end of the ash cleaning component 12, and the electromagnetic valve 15 is connected with the magnetic part in an adsorption manner in a power-on state; when the magnitude of the differential pressure reaches the differential pressure threshold, the solenoid valve 15 is de-energized. In use, when the magnitude of the pressure difference across the filter assembly 13 is smaller than the pressure difference threshold, the electromagnetic valve 15 is in the power-on state and the ash removal assembly 12 is in the initial position, and at this time, the electromagnetic valve 15 adsorbs the magnetic component on the movable end of the ash removal assembly 12. In this manner, the structural stability of the ash removal assembly 12 in the initial position is facilitated to be improved. When the pressure difference between the two sides of the filtering component 13 reaches the pressure difference threshold value, the electromagnetic valve 15 is powered off, at this time, the electromagnetic valve 15 cannot magnetically adsorb the magnetic part of the movable end, and the movable end of the ash cleaning component 12 conveniently moves towards the second wall surface under the driving of the driving unit.
Further, the ash removal component 12 comprises a base and an acoustic wave device arranged on the base, one end of the base is a fixed end of the ash removal component 12, the other end of the base is a movable end of the ash removal component 12, and a horn end of the acoustic wave device corresponds to the filter component 13. At this time, when the ash removing assembly 12 is located at the cleaning position, the dust accumulated on the filter assembly 13 is vibrated away from the filter assembly 13 by the sound energy generated by the sound wave device.
Alternatively, the number of the acoustic wave devices is plural, the plural acoustic wave devices are uniformly distributed on the base, and the horn ends of the plural acoustic wave devices face the same side of the base, that is, the side capable of facing the filter assembly 13.
The sound wave device uses compressed air as the energy source of sound wave, the high-strength titanium metal membrane self-oscillates under the action of compressed air source and generates resonance in the resonant cavity to convert the potential energy of compressed air into low-frequency sound energy, the sound energy is transmitted to corresponding ash deposition points through air medium, so that the sound wave plays a role of 'sound induced fatigue' on ash slag.
It should be noted that, when the ash removal assembly 12 is used for removing ash, the filter device is still in the air intake stage, and the air intake 111 is still in the air intake stage.
Further, the filter device further comprises a fan, and the fan can be arranged in the filter chamber or outside the housing 11. The blower is used for blowing or drawing air outside the housing 11 into the filter chamber from the air inlet 111 during rotation, and also for drawing air inside the filter chamber out of the housing 11. In practical use, after the dust on the filter assembly 13 is removed by the acoustic wave device, the air with dust in the filter chamber is extracted from the filter chamber by the reverse air extraction of the fan, so as to achieve the purpose of thoroughly cleaning the dust.
Of course, when the filter device is used as a part of the air cleaning device, the filter device itself may not include a fan, and the fan of the air cleaning device may be connected to the air inlet 111 to achieve the purpose of reverse air draft for ash removal.
In one embodiment, the first wall surface is a top surface, the second wall surface is a bottom surface, the driving unit includes a first power source, a fixed pulley 16 and a rope 17, the power source is disposed on the housing 11, the fixed pulley 16 is rotatably disposed on the first wall surface along its axis, one end of the rope 17 is wound on the fixed pulley 16, the other end of the rope 17 is connected to the movable end of the ash removal assembly 12, and the first power source is in transmission connection with the fixed pulley 16 for driving the fixed pulley 16 to rotate. In practical use, when the movable end of the ash removal component 12 needs to clean the filter component 13, the first power source drives the fixed pulley 16 to rotate clockwise (or anticlockwise) and unreel the rope 17, so that the length of the rope 17 between the movable end of the ash removal component 12 and the fixed pulley 16 is increased, and at the moment, the movable end of the ash removal component 12 falls to a position connected with the bottom surface under the action of gravity to reach a cleaning position; when the movable end of the ash removal component 12 needs to be stored, the first power source reversely drives the fixed pulley 16 to rotate and wind the rope 17, so that the length of the rope 17 between the movable end of the ash removal component 12 and the fixed pulley 16 is shortened, and at the moment, the movable end of the ash removal component 12 returns to the initial position under the pulling of the rope 17.
