In order to enable the second rotating shaft 12 to rotate for one circle and to toggle the pin 4 to reciprocate once, a shell 15 is sleeved outside the pin 4, the shell 15 is fixed inside the box body 1, a pressure spring 16 is installed between the pin 4 and the shell 15, and a first toggle lever 17 is fixed on the pin 4; the second rotating shaft 12 is provided with a wheel 18, the wheel 18 is provided with a second deflector rod 19 which can move the first deflector rod 17, the second rotating shaft 12 drives the wheel 18 to rotate for one circle, and the second deflector rod 19 moves the first deflector rod 17 once.
In order to ensure the stable rotation of the cylinder 201, a plurality of rollers 20 clamped around the cylinder 201 are installed on the front and rear side surfaces of the box body 1.
In order to ensure better filtration of the contaminated water, the disc 202 is in clearance fit with the side wall of the tank 1.
In order to realize that the vertical shaft 6 drives the second rotating shaft 12 to rotate intermittently, the vertical shaft 6 is provided with an incomplete gear 21, a plurality of supporting plates 23 are fixed on the rear side surface of the box body 1, vertical intermediate shafts 24 are arranged on the supporting plates 23, the intermediate shafts 24 are provided with complete gears 22 meshed with the incomplete gears 21, and the intermediate shafts 24 and the second rotating shaft 12 are linked through bevel gear sets.
In order to realize that the vertical shaft 6 drives the first rotating shaft 10 to rotate, the vertical shaft 6 and the first rotating shaft 10 are linked through a bevel gear set.
In order to realize the installation of the pipeline 5, the front end and the rear end of the pipeline 5 are arranged at the front side and the rear side of the box body 1, a vertical supporting rod 25 is fixedly installed at the front end and the rear end of the pipeline 5, and the lower end of the supporting rod 25 is fixed on the ground.
In order to enable sundries to slide down along the flat plate 9, the left end and the right end of the flat plate 9 are arranged on the outer side of the box body 1.
When the device is used, the position of the device is needed to be arranged firstly, and the device is arranged at a low position, such as a position between floors of a sewage treatment plant, because the dead weight of water is utilized, so that sewage is filtered by the device and flows into the next layer; or according to the situation on site, the water level difference is reasonably utilized, so that the device is arranged at a low position to be convenient for receiving sewage flow.
After the installation site is selected, the device may be secured, the secured device being as shown in fig. 1 and 2. Then the sewage can enter through the water inlet 3 above the box body 1.
In the initial state, the whole state is as shown in fig. 1, the number of the partition plates 203 is four, the water inlet 3 is positioned between the two partition plates 203, and the water inlet 3 is inclined toward the left side, so that the whole filter 2 has a tendency to rotate to the left by the impact of the sub-water flow, but the whole filter 2 cannot rotate at this time because the pin 4 is in a state of blocking the partition plates 203.
After the sewage is filtered by the screen 204 in the middle of the filter 2, impurities can remain between the two partition plates 203, and the filtered sewage can flow down from the screen 204, flow into the pipe 5 and then flow backwards along the pipe 5.
Because the vertical shaft 6 is arranged on the pipeline 5, the vertical shaft 6 is provided with the impellers 7, and the sizes of the impellers 7 are sequentially reduced from top to bottom, when water in the pipeline 5 flows, no matter the height of the water level, the water flow can blow the impellers 7 to rotate; which in turn keeps the vertical shaft 6 rotating. After the vertical shaft 6 rotates, the vertical shaft 6 and the first rotating shaft 10 are linked through the bevel gear set, so that the first rotating shaft 10 can drive the plurality of cams 11 arranged on the first rotating shaft 10 to rotate, and the cam 11 is contacted with the lower side surface of the right end of the flat plate 9, so that the flat plate 9 can swing back and forth with the hinge point at the left end as the middle under the action of gravity of the flat plate 9 and the rotation of the cam 11, and thus, sundries attached to the flat plate 9 can be vibrated to fall; the sundries are prevented from being attached, and the sundries can fall and be collected quickly.
On the other hand, when the vertical shaft 6 rotates, the vertical shaft 6 can drive the intermediate shaft 24 to intermittently rotate through the cooperation of the incomplete gear 21 on the vertical shaft 6 and the complete gear 22 on the intermediate shaft 24, and then the intermediate shaft 24 drives the second rotating shaft 12 to intermittently rotate through the bevel gear set.
Because the wheel 18 is installed on the second rotating shaft 12, and the second driving lever 19 is arranged on the wheel 18, the wheel 18 can drive the first driving lever 17 after the wheel 18 contacts the first driving lever 17 along with the gradual stepping of the wheel 18; the first driving lever 17 drives the pin 4 to be compressed; the pin 4 is now not blocking the partition 203, and the entire filter 2 can then be rotated by the impact of the water flow.
Because the contact time of the second shift lever 19 and the first shift lever 17 is short, when the second shift lever 19 is separated from the contact time of the first shift lever 17, the pin 4 is reset under the action of the compression spring 16 and is positioned at a position capable of blocking the partition 203; as the filter 2 is rotated ninety degrees, the next partition 203 will again be blocked by the pin 4, stabilizing the filter 2.
In the process of rotating the filter 2, the impurities which are originally positioned above the filter 2 can rotate downwards along with the filter 2 and gradually rotate to the downward position, so that the impurities fall onto the flat plate 9; then, the materials slide down along the flat plate 9 by the vibration of the flat plate 9 and are collected by a subsequent device; therefore, along with the rotation of the filter 2, the impurities originally above the filter 2 can be separated from the filter 2, and after being turned over, the impurities are separated from the filter 2, so that the cleanness of the filter 2 is kept; meanwhile, the clean area of the filter screen 204 after deslagging rotates to the upper part again for filtering operation.
According to the device, the impellers 7 are arranged in the pipeline 5, so that the vertical shaft 6 is rotated by utilizing water conservancy, on one hand, the vibration of the flat plate 9 is realized, the material accumulation and adhesion on the flat plate 9 are avoided, and the rapid blanking is convenient; on the other hand, the extension and retraction of the control pin 4 are realized, so that the rotation and the stop of the filter 2 are indirectly controlled, the filter 2 is directly pushed to rotate reversely by using the impact force and the gravitational potential energy of water without additional power, and the self-cleaning of the filter screen 204 is realized.
The device is provided with the rotatable filter 2, and the plurality of partition plates 203 are arranged in the filter 2, so that the device has the function of dividing areas on one hand, and the partition plates 203 and the pins 4 have the function of limiting on the other hand; the water outlet is obliquely arranged, so that the filter 2 always has a rotating trend, and when the pin 4 is not positioned on the limiting partition plate 203, the impact of water flow can enable the filter 2 to rotate, so that sundries are rotated to the lower part, and automatic cleaning is realized.
The invention has the advantages of convenient operation, ingenious structure, low cost, convenient manufacture, safety and effectiveness, greatly improves the speed and the quality of sewage filtration, simplifies the operation, saves the power and realizes the unattended automatic work.
