The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
As shown in fig. 1 to 8, an exhaust gas filtering and purifying apparatus of the present invention includes: the device comprises a box body 1, a filter screen 2 for filtering solid particles in waste gas, a cleaning component 3 for cleaning the filter screen 2, a cleaning component 4 for cleaning the filter screen 2, a pressurizing component 5 for discharging the solid particles and a control component.
The cleaning unit 3 includes: a cleaning brush 31 for cleaning the air inlet side of the filter screen 2, a forward and reverse rotation motor 32 for driving the cleaning brush 31 to clean the filter screen 2, and a transmission assembly 33 for transmitting the power of the forward and reverse rotation motor 32.
A collecting plate 6 is arranged below the filter screen 2, and the collecting plate 6 is used for collecting solid particles swept down by the filter screen 2 by a cleaning brush 31 and collecting impurities generated by the cleaning component 4 for cleaning the filter screen 2; a collecting cavity 11 is arranged below the collecting plate 6, and the collecting cavity 11 is used for collecting solid particles and impurities collected by the collecting plate 6; wherein the collecting plate 6 is an arc-shaped collecting plate 6, so that the flow direction of solid particles and impurities can be guided.
The bottom of the arc-shaped collecting plate 6 is provided with an impurity outlet 61, and the impurity outlet 61 is positioned below the filter screen 2 so as to collect solid particles on the filtering side of the filter screen 2 and impurities on the non-filtering side of the filter screen 2 respectively; the impurity outlet 61 is formed by the staggered arrangement of the inclined plate one 611 and the inclined plate two 612, and the gap of the impurity outlet 61 gradually reduces from top to bottom so as to facilitate the discharge of the upper solid particles into the collecting chamber 11 below, and simultaneously inhibit the upward backflow of air in the collecting chamber 11.
The pressurizing assembly 5 includes: a push block 51 slidably installed in the collection chamber 11, a check valve fixedly installed on the push block 51; the push block 51 is matched with the collecting cavity 11 to achieve a good sealing effect; the collecting cavity 11 is provided with a drain 111 at one side of the push block 51 in the forward direction, as shown in fig. 8; the push block 51 is fixedly arranged on the second rack 333, the push block 51 is driven to move by the second rack 333, and the pressure of the collecting cavity 11 is continuously increased in the reciprocating motion of the push block 51 by arranging a one-way valve, so that the pressure difference is generated between the inside and the outside of the collecting cavity 11, and when the pressure in the collecting cavity 11 reaches a threshold value, solid particles in the collecting cavity 11 are discharged from the sewage outlet 111; as can be seen from the above description, the collecting chamber 11 generates periodic pressure fluctuations during the movement of the push block 51, so that the collecting chamber 11 can suck solid particles accumulated above the impurity outlet 61 from the impurity outlet 61 on the one hand, and can discharge the solid particles collected in the chamber from the drain 111 on the other hand; thus, through the cooperation of the push block 51, the impurity outlet 61 and the collecting cavity 11, not only the solid particles generated during cleaning can be collected, but also the solid particles accumulated at the impurity outlet 61 can play a certain role in preventing waste gas leakage, and the solid particles in the collecting cavity 11 can be cleaned periodically.
As an alternative to this embodiment, as shown in fig. 5 to 6, the bottom surface of the collecting chamber 11 gradually slopes downward along the extending direction of the pushing block 51, so that the collected solid particles move downward under their own gravity, facilitating cleaning; the bottom surface of the collecting cavity 11 is coated with a belt, and a rotating plate is uniformly and rotatably arranged on the belt; when the push block 51 extends, the rotating plate in the extending direction of the push block 51 is abutted against the push block 51, so that the belt is driven to move forwards in the extending process of the push block 51; when the push block 51 is retracted, the rotating plate in the retraction direction of the push block 51 is forced to rotate in the horizontal direction so as to avoid interference with the push block 51, and when the push block 51 is retracted to the rear side of the rotating plate in the retraction direction, the rotating plate in the retraction direction is rotated upwards by the elastic force of a spring so as to be abutted with the push block 51 when the push block 51 is pushed out again, so that the belt is driven to move; in this way, during the expansion and contraction process of the push block 51, the belt can be continuously driven to move forward, so that the impurities remained on the belt are continuously brought to the sewage outlet 111; when the belt transmission is arranged, the tightness of the collecting cavity 11 can be considered, so that the belt can be further added on the basis of the former scheme, and solid particles can be discharged only through the belt transmission, and the device can be flexibly selected according to actual working conditions.
The impurity outlet 61 is rotatably provided with a discharging baffle 613 and a torsion spring for driving the discharging baffle 613 to reset after rotation, when the push block 51 is retracted, the discharging baffle 613 seals the impurity outlet 61, the push block 51 extends out, and when the pressure in the collecting cavity 11 reaches a certain degree, the discharging baffle 613 is acted by the pressure to open the impurity outlet 61 so as to discharge solid particles collected in the arc-shaped collecting plate 6 into the collecting cavity 11, and simultaneously, under the pressure of the reciprocating motion of the push block 51, the solid particles are discharged from the sewage outlet 111; the discharge baffle 613 does not exceed the bottom of the impurity outlet 61 when being inclined downward; the discharging baffle 613 is fixedly provided with a sealing gasket for sealing the impurity outlet 61 to prevent air leakage; as can be seen from the above description, the discharging baffle 613 is periodically opened and closed during the movement of the push block 51, so that not only can a good sealing effect be achieved, the push block 51 is hardly affected to pressurize the collecting cavity 11, the leakage of waste gas is reduced as much as possible, but also solid particles can be discharged during the movement of the push block 51; it should be noted that, in the case where the discharge damper 613 is not provided, the impurity outlet 61 may also have a certain effect of preventing the air from flowing back, and the discharge damper 613 is provided so as to further enhance the effect, and the pressure in the collection chamber 11 does not drop sharply when the discharge damper 613 opens the impurity outlet 61.
The transmission assembly 33 includes: a driving gear 331 mounted on the output shaft of the forward and backward rotation motor 32, a first rack 332 driving the cleaning brush 31 to move up and down, and a second rack 333 driving the push block 51 to extend and retract transversely; the first rack 332 and the second rack 333 are respectively meshed with the driving gear 331 so as to respectively drive the first rack 332 and the second rack 333 to move through the rotation of the driving gear 331; the first rack 332 and the second rack 333 are arranged in a staggered mode, the first rack 332 and the second rack 333 are respectively and correspondingly arranged in rack mounting grooves, and the rack mounting grooves are respectively and slidably arranged on corresponding tracks to avoid interference.
The cleaning assembly 4 comprises: a spray head 41 for spraying water to the air outlet side of the filter screen 2, and a driven gear 42 for driving the spray head 41 to swing reciprocally; the driven gear 42 is meshed with the second rack 333 and driven by the second rack 333; when the second rack 333 reciprocates, the driven gear 42 is driven to reciprocate, so that the spray head 41 is driven to reciprocate, and the effect of fully spraying water on the non-filtering side of the filter screen 2 is achieved; in order to prevent the driven gear 42 from rotating too many turns, an overrunning clutch can be arranged between the driven gear 42 and the spray head 41 or the size of the gear can be adjusted according to the situation; as can be seen from the above description, when the second rack 333 moves, it not only drives the push block 51 to move, but also drives the spray head 41 to swing, so that not only can the spray head 41 spray water to clean the filter screen 2, but also impurities generated by cleaning can be pumped away by the push block 51; as an alternative of this embodiment, the nozzle 41 is a high-pressure atomizing nozzle, and the nozzle 41 intermittently sprays high-pressure gas, so that the solid particles on the surface of the filter screen 2 can be cleaned, and at the same time, the filter screen 2 and the air around the filter screen 2 vibrate, and the filtering side and the non-filtering side of the filter screen 2 can be further cleaned, and the air vibration layer formed by vibration can further avoid the adhesion of the solid particles on the filter screen 2; in addition, negative pressure is formed in the continuous movement process of the push block 51, so that solid particles floating in the air can be conveniently pumped away, and the cleaning effect is better; in the above two modes, the water is cleaned up, but the sewage generated by cleaning is also required to be treated, so that the water spray cleaning or the air injection cleaning in the actual production process and the number of the spray heads 41 can be flexibly selected according to the actual working condition.
Therefore, when the forward and reverse rotation motor 32 works, the driving gear 331 is driven to rotate, and the first rack 332 is driven to move up and down so as to drive the cleaning brush 31 to clean the filter screen 2; when the driving gear 331 rotates, the second rack 333 is further driven to transversely extend and retract, so as to drive the spray head 41 to swing to spray water or jet air, and simultaneously drive the push block 51 to reciprocate so as to discharge solid particles, impurities or sewage.
The control assembly includes: a detecting unit 72 for detecting the air volume of the air outlet side of the box body 1, and a control unit 71 for controlling the operation of the forward and reverse rotation motor 32 according to the air volume detected by the detecting unit 72; when the air volume measured by the detection unit 72 is lower than the threshold value, which indicates that the filter screen 2 is blocked, the control unit 71 controls the forward and reverse rotation motor 32 to rotate so as to enable the cleaning brush 31 to clean the filter screen 2, meanwhile, the control unit 71 opens the electromagnetic valve of the spray head 41, and the spray head 41 swings under the drive of the second rack 333 while spraying water or spraying air, so that the filter screen 2 is washed; simultaneously, the second rack 333 drives the push block 51 to move, so that the drain outlet 111 of the collecting cavity 11 generates negative pressure, and solid particles brushed by the cleaning brush and waste water generated by the cleaning filter screen 2 are discharged; when the air volume measured by the detecting unit 72 is greater than or equal to the threshold value, which indicates that the filter screen 2 is cleaned or no cleaning is required, the control unit 71 controls the forward and reverse rotation motor 32 to stop working, and at this time, the exhaust gas is filtered normally through the filter screen 2.
The air pressure sensor is further installed in the collecting cavity 11, the second electromagnetic valve is further installed on the sewage outlet 111, through the design of the impurity outlet 61 and the discharging baffle 613, air backflow in the collecting cavity 11 can be limited as much as possible, air pressure in the collecting cavity 11 can continuously rise in the process that the pushing block 51 continuously moves, when the air pressure in the collecting cavity 11 exceeds a threshold value set by the air pressure sensor, the control unit 71 controls to open the second electromagnetic valve, and at the moment, solid particles in the collecting cavity 11 are sprayed out from the sewage outlet 111 under the action of pressure.
Working principle: when the air volume measured by the detection unit 72 is lower than the threshold value, the control unit 71 controls the forward and reverse rotation motor 32 to periodically forward and reverse rotation to drive the driving gear 331 to periodically forward and reverse rotation, so as to drive the first rack 332 to move up and down in a reciprocating manner, and further drive the cleaning brush 31 to clean the filtering side of the filter screen 2 through the first rack 332; meanwhile, the driving gear 331 drives the second rack 333 to horizontally move, so as to drive the push block 51 to reciprocate, and continuously pressurize the collecting cavity 11 under the action of the one-way valve; the second rack 333 moves horizontally and drives the spray head 41 to swing, so as to spray water to clean the non-filtering side of the filter screen 2; when the pressure in the collection chamber 11 reaches a threshold value, the drain 111 is opened to discharge the solid particles.
