the filter 8 comprises a vertical cylinder 801, the cylinder 801 is rotatably mounted on the turntable 7, a vertical guide rod 802 is mounted at the center of the cylinder 801, the guide rod 802 can move up and down, a filter screen 803 is mounted on the upper end surface of the cylinder 801, the middle of the filter screen 803 is fixedly connected with the upper end of the guide rod 802, and a balancing weight 804 is mounted at the lower end of the guide rod 802; a slag box 807 is sleeved outside the cylinder body 801, and the slag box 807 moves up and down along with the guide rod 802.
In order to realize dust washing, the dust collector adopts a wet dust collector.
In order to stabilize the pressure and speed of water discharged from the water discharge hole 6, the interior of the upper box 2 is divided into an upper chamber 201 and a lower chamber 202 by a partition, a water inlet pipe 203 arranged in the lower chamber 202 is installed at the bottom of the upper chamber 201, and a float valve 204 is installed at the bottom of the water inlet pipe 203.
For better slag receiving, the slag box 807 is a cylindrical box body, the upper end of the box body is provided with a funnel-shaped water guide edge 808, a cross brace 810 is arranged inside the box body, and the middle part of the cross brace 810 is connected with the guide rod 802 through a vertical connecting rod 809.
In order to realize the up-and-down movement of the guide rod 802, a collar 805 capable of moving up and down along the sleeve 4 is arranged inside the cylinder 801, and the outer edge surface of the guide rod 802 is fixed on the collar 805 through a plurality of support rods 806.
For better filtering, the filtering net 803 has certain elasticity, and the weight block 804 is a sphere.
In order to realize the rotation of the rotating disc 7, the rotating shaft 5 is driven by a motor to rotate.
In order to realize slag receiving, when the guide rod 802 is at the lowest position of the stroke, the lower end of the edge corresponds to the upper end of the cylinder 801.
When the invention is used, firstly, water is added into the upper tank body 2, because the upper tank body 2 is divided into the upper chamber 201 and the lower chamber 202, and the lower chamber 202 controls the water entering the lower chamber 202 from the upper chamber 201 through the float valve 204, the maximum water level of the lower chamber 202 can be controlled at a set value. In the initial state, the water level in the lower chamber 202 is clean, and at this time, the water can directly flow downwards through the water discharge hole 6; since each drain hole 6 corresponds to each filter 8 and the upper case 2 and the turntable 7 rotate together; therefore, the drain hole 6 can be ensured to always correspond to one filter 8; the filtered water enters the inside of the lower case 3.
The dust is pumped into the dust scrubber 1 by a pump, so that atomized water drops or dense water flow is contacted with the dust to enable the dust to be melted into the water flow; the used water is returned to the inside of the water tank by the pump.
At this point the water has begun to contain impurities; need the starter motor, make the motor drive whole carousel 7 and go up box 2 and rotate, the pivoted in-process can filter.
Firstly, the rotation of the rotating shaft 5 makes the filters 8 revolve with the rotating disc 7, each filter 8 rotates due to the engagement of the gear 10 on the filter 8 and the inner gear ring 11 while each filter 8 revolves, and after the filter 8 rotates, the torsion spring 9 between the filter 8 and the rotating disc 7 is twisted, and then elastic potential energy is stored.
Because the slope-shaped convex section 13 is arranged on the right side of the bottom plate, the part of the inner gear ring 11 is the toothless section 12, and the baffle 15 fixed on the lower box body 3 can also block the water drainage hole 6 which rotates to the part, the slag throwing operation can be carried out after the filter 8 rotates to the part, so that sundries on the filter screen 803 are thrown away, and the filter screen 803 is dredged. The specific working principle is as follows.
Firstly, when the filter 8 is on the left side, the weight 804 at the lower end of the guide rod 802 is placed on the bottom plate, and the bottom plate on the left side is lower, so the middle of the filter screen 803 is lower than the periphery of the filter screen 803, and the filter screen 803 presents an inverted cone with a large upper end and a sharp lower end, and the lower end of the guide rod 802 is supported, the stress on the filter screen 803 is smaller, so that the deformation of the filter screen 803 can be ignored, the gap of the filter screen 803 is smaller, and the filtering effect is better. Meanwhile, the inverted cone shape can prevent liquid leakage and improve the filtering speed and the filtering effect. Meanwhile, the slag box 807 is also at a low position of the stroke, referring to fig. 5, the water guide edge 808 on the slag box 807 corresponds to the cylinder 801 at this time, so that water can conveniently enter the cylinder 801.
When the filter 8 rotates to the right side along with the rotary disc 7, the lower end of the guide rod 802 passing through the inside of the filter 8 is jacked up by the raised section 13 of the bottom plate, so that the guide rod 802 moves upwards until the middle of the filter screen 803 is higher than the periphery of the filter screen 803, i.e. the filter screen 803 presents a conical shape with a sharp upper end and a big lower end; meanwhile, the guide rod 802 is upward to deform the filter screen 803 under stress, that is, the gap between the filter screen 803 is enlarged; the sundries clamped inside can be thrown out more quickly. Meanwhile, after the filter 8 rotates to the right side, the gear 10 on the filter 8 is matched with the toothless section 12 of the inner gear ring 11, at the moment, the cylinder 801 rotates reversely at a high speed under the action of the torsion spring 9, and impurities on the filter screen 803 are thrown into the material receiving groove under the action of centrifugal force. During the throwing of the screen 803, the right baffle 15 blocks the drain hole 6, and the filter 8 is suspended from the filtering operation. Meanwhile, after the guide rod 802 rises, the slag box 807 is driven to rise together, so that the middle of the slag box 807 corresponds to the upper end of the cylinder 801, namely the filter screen 803 corresponds to the middle of the slag box 807, and thrown impurities fall into the slag box 807; and (4) collecting.
Then, the filter 8 continues to rotate, and the guide rod 802 is first reset by gravity, so that the filter screen 803 and the slag box 807 are both restored to the original state.
Because the filter screen 803 has small gap and low filtering speed, the flow rate and pressure of the water discharge hole 6 can be controlled by controlling the height of the liquid level of the lower chamber 202 in the upper box body 2, so that untimely filtering is avoided; ensuring the full filtration.
A plurality of filters 8 in this device cycle work to at the endless in-process, every rotation just can the automatic shutdown filter to the right side, and through reverse deformation and tensile, and cooperate the centrifugation to clear up, through the high-speed rotation of torsional spring 9, can make the strong debris of adhesion such as thin debris or mud on the filter screen 803 thrown away, and collect.
In the device, each filter 8 can automatically accumulate force during revolution and then release and rotate reversely, and no additional power source is needed, so that the device is simple and efficient.
Filter screen 803 circulation work can make the filtration be in the state of serialization in this device, and rivers in whole water tank are in the state that flows always promptly, have guaranteed the continuity of supplying water, and the water yield is not enough in the box 3 under preventing, and the cavitation that causes is bound, the dust scrubber 1 circumstances such as out of work.
