Description

TECHNICAL FIELD

[0039] The water blocking plate 31 is installed in the inside of the capturing box 8 by the top pressure spring, so that the water blocking plate 31 keeps in contact with the water permeable plate 30 in real time, the size of the water blocking plate 31 is smaller than that of the water permeable plate 30, when the water blocking plate 31 is in contact with the water permeable plate 30, a water storage chamber can be isolated in the inside of the capturing box 8, when the water permeable plate 30 is separated from the water blocking plate 31, water can pass through the water permeable plate 30 and enter the water storage chamber from the gap between the water permeable plate 30 and the water blocking plate 31.

[0040] When the supporting rod 4 drives the capturing box 8 to rotate counterclockwise in the sewage pool 1, the suspended solids in the sewage can be filtered by the intercepting plate 14, at the same time, the movement of the capturing box 8 increases the resistance of the sewage to the water blocking plate 31, the water blocking plate 31 is pushed to slide towards the direction away from the water permeable plate 30 by the water pressure, and the sewage can enter the water storage chamber through the gap between the water blocking plate 31 and the water permeable plate 30.

[0046] When the catch box 8 is rotated to the horizontal state by the supporting rod 4, the water in the water storage chamber is reversed until the water level is higher than the opening of the siphon pipe 33, and then the water is sent into the inner cavity of the spray washing box 20 through the water sending pipe 35 under the siphon effect, so as to facilitate the backwashing of the spray washing box 20 to the intercepting plate 14.

[0047] The side wall of the supporting rod 4 is fixedly provided with a fixed rod 23, the inside of the fixed rod 23 is rotatably provided with a rotating rod 22, the inside of the rotating rod 22 is elastically provided with a clamping block 24, one end of the clamping block 24 is obliquely provided, and the fixed rod 23 is provided with a gap for the clamping block 24 to extend out;

[0048] The rotating rod 22 can rotate a certain distance in the inside of the fixed rod 23, when the rotating rod 22 rotates clockwise in the inside of the fixed rod 23, the clamping block 24 can be rotated, and the clamping block 24 can be pushed into the inner cavity of the rotating rod 22 by the oblique surface of the clamping block 24 being pressed by the inner wall of the gap.

[0049] The side wall of the catch box 8 is fixedly provided with a transmission cylinder 36, and the fixed rod 23 is rotatably arranged in the inside of the transmission cylinder 36.

[0050] The catch box 8 can rotate on the outer wall of the fixed rod 23 through the transmission cylinder 36.

[0051] The inner wall of the transmission cylinder 36 is provided with a first clamping groove 25 and a second clamping groove 26 for the clamping block 24 to be inserted;

[0052] The clamping block 24 on the rotating rod 22 can be inserted into the first clamping groove 25 or the second clamping groove 26 through the gap, when the clamping block 24 is inserted into the first clamping groove 25, the plane of the clamping block 24 will clamp the first clamping groove 25 and limit the clockwise rotation of the transmission cylinder 36, therefore, the current catch box 8 cannot rotate, and will remain in the vertical state, and the rotation of the catch box 8 can fish the suspended solids in the sewage through the vertical catch box 8.

[0053] When the clamping block 24 is inserted into the second clamping groove 26, the catch box 8 will be in a horizontal state, which is convenient for the backwashing of the spray washing box 20 to the intercepting plate 14.

[0054] The outer wall of the fixed rod 23 is fixedly provided with a limiting block 27, and the inner wall of the transmission cylinder 36 is provided with a limiting groove 28.

[0055] The limiting block 27 and the limiting groove 28 can control the rotation angle of the transmission cylinder 36 on the outer wall of the fixed rod 23 to be 90°, so that the catch box 8 can only rotate from vertical to horizontal or from horizontal to vertical.

[0056] A first torsional spring is arranged between the transmission cylinder 36 and the supporting rod 4, one end of the rotating rod 22 away from the transmission cylinder 36 penetrates the supporting rod 4 and is fixedly provided with a rotating gear 13, and a second torsional spring is arranged between the rotating rod 22 and the supporting rod 4.

[0057] When the capture box 8 is in the vertical state, the first torsion spring is in the normal state, and when the capture box 8 is in the horizontal state, the first torsion spring is deformed and stores elastic potential energy.

[0058] When the rotating rod 22 drives the clamping block 24 to be inserted with the notch, the second torsion spring is in the normal state, and when the rotating rod 22 rotates counterclockwise to release the insertion of the clamping block 24 with the notch, the second torsion spring is in the deformed state.

[0059] The inner wall of the sewage tank 1 is fixedly installed with the first guide gear 6 and the second guide gear 7 which are engaged with the rotating gear 13.

[0060] When the capture box 8 is located directly below the filtering box 3, the capture box 8 is in the vertical state, and as the capture box 8 rotates clockwise, the rotating gear 13 on the supporting rod 4 will first contact the first guide gear 6 and control the rotating rod 22 to drive the clamping block 24 to rotate clockwise, so that the clamping block 24 is disengaged from the first clamping groove 25. During the movement of the capture box 8, not only the suspended solids in the sewage can be salvaged through the intercepting plate 14, but also part of the sewage can be sent into the water storage chamber for storage. At this time, after the capture box 8 stores the sewage, the weight increases, which drives the capture box 8 to rotate to the horizontal state, and the first torsion spring is deformed and stores elastic potential energy, until the rotating gear 13 is separated from the first guide gear 6. At this time, the second torsion spring releases the elastic potential energy and drives the rotating rod 22 to reset, the clamping block 24 reinserts the notch and is clamped with the second clamping groove 26. At this time, the capture box 8 is also in the horizontal state, and the water is sent into the inner cavity of the spray washing box 20 through the water sending pipe 35 under the effect of the siphon, and the suspended solids on the intercepting plate 14 are flushed into the inside of the filtering box 3 for storage. At this time, the supporting rod 4 drives the rotating gear 13 to contact the second guide gear 7, controls the rotating rod 22 to rotate clockwise, and releases the clamping of the clamping block 24 with the second clamping groove 26. At this time, the first torsion spring releases the elastic potential energy, controls the transmission cylinder 36 to rotate counterclockwise with the capture box 8, and makes the capture box 8 parallel to the supporting rod 4.

[0061] The bottom end of the capture box 8 is fixedly installed with the installation box 9, the inside of the installation box 9 is rotatably installed with the winding wheel 18 through the coil spring, the winding wheel 18 and the spray washing box 20 are connected through the pull rope 29, the side wall of the winding wheel 18 is fixedly installed with the ratchet wheel 15, the inside of the installation box 9 is elastically installed with the ratchet rod 16 for blocking the ratchet wheel 15, and the top end of the spray washing box 20 is fixedly installed with the floating air bag 21.

[0062] When the capture box 8 is located in the sewage, at this time the floating air bag 21 will drive the spray washing box 20 to slide upwards in the inside of the capture box 8, it should be noted that the water outlet on the spray washing box 20 needs to be set as one-way in and out, which can only spray out from inside to outside, at the same time, pulling the pull rope 29 makes the winding wheel 18 unwind, and the coil spring will also deform and store elastic potential energy, at this time the unwinding direction of the winding wheel 18, the ratchet rod 16 will not block the rotation direction of the ratchet wheel 15, when the capture box 8 rotates to the top of the filter box 3 and is in a horizontal state, the water in the storage chamber is sent into the inside of the spray washing box 20 through siphon, which back-flushes the interception plate 14, at the same time, the ratchet rod 16 removes the blockage of the ratchet wheel 15, the coil spring releases the elastic potential energy, and the control spray washing box 20 reversely slides in the inside of the capture box 8, which can back-flush the interception plate 14 in a full range.

[0063] The side wall of the supporting rod 4 is fixedly installed with an arc-shaped tooth plate 11, the inside of the capture box 8 is rotatably installed with a winding wheel 19, the winding wheel 19 is connected with the ratchet rod 16 through a connecting rope 17, one end of the winding wheel 19 extends out of the outside of the capture box 8 and is fixedly installed with a transmission gear 12 which is engaged with the arc-shaped tooth plate 11.

[0064] When the capture box 8 rotates from vertical to horizontal, at this time the transmission gear 12 arranged on the capture box 8 will contact with the arc-shaped tooth plate 11, which controls the transmission gear 12 to rotate and drives the winding wheel 19 to wind the connecting rope 17, thereby removing the blockage of the ratchet rod 16 to the ratchet wheel 15, the ratchet rod 16 is elastically installed in the inside of the installation box 9, when the transmission gear 12 is separated from the arc-shaped tooth plate 11, the ratchet rod 16 will block the ratchet wheel 15 again.

[0065] The interception plate 14 is slidably installed with a cleaning block 10, the water spraying end of the spray washing box 20 is magnetically attracted to the cleaning block 10.

[0066] When the spray washing box 20 slides, the cleaning block 10 can be driven by magnetic force to scrape the interception plate 14, thereby assisting the spray washing box 20 to clean the interception plate 14 through back-flushing.

[0067] After the starting motor 2, its output shaft drives the rotating block 5 to rotate, the rotating block 5 drives the support rod 4 and the capture box 8 between the support rods 4 to rotate clockwise in the sewage pool 1, at this time the clamping block 24 on the rotating rod 22 is inserted with the first clamping slot 25 of the transmission cylinder 36, the rotation of the capture box 8 is limited to keep it vertical, the interception plate 14 intercepts the suspended solids in the sewage during the rotation of the capture box 8, at the same time the resistance generated by the flow of sewage pushes the water blocking plate 31 away from the water permeable plate 30, the sewage enters the water storage chamber through the gap between the water permeable plate 30 and the water blocking plate 31 for storage, in this process, the floating air bag 21 drives the spray washing box 20 to slide upwards, pulls the pull rope 29 to make the winding wheel 18 unwind, the coil spring deforms to store energy and the ratchet rod 16 does not block the rotation of the ratchet wheel 15; when the support rod 4 drives the capture box 8 to rotate to the top of the filtering box 3, the rotating gear 13 at the end of the rotating rod 22 engages with the first guide gear 6, drives the rotating rod 22 to rotate in the fixed rod 23, the clamping block 24 is pressed by the inclined surface of the clamping block 24 in the gap of the fixed rod 23 to make the clamping block 24 retract into the inner cavity of the rotating rod 22, the clamping block 24 is released from the clamping of the first clamping slot 25, under the weight of the capture box 8 and the deformation of the first torsion spring, the capture box 8 rotates on the outer wall of the fixed rod 23 through the transmission cylinder 36, the limiting block 27 cooperates with the limiting slot 28 to limit the rotation angle of 90°, the capture box 8 switches to the horizontal state, the clamping block 24 extends under the action of the second torsion spring and is inserted with the second clamping slot 26; in the horizontal state of the capture box 8, the sewage in the water storage chamber changes direction, the water level is higher than the opening of the siphon pipe 33, under the siphon effect, the sewage is sent into the inner cavity of the spray washing box 20 through the siphon pipe 33 and the water delivery pipe 35, at the same time, the transmission gear 12 engages with the arc-shaped toothed plate 11 during the state switching of the capture box 8, drives the tightening wheel 19 to rotate and wind the connecting rope 17, releases the ratchet rod 16 from blocking the ratchet wheel 15, the coil spring releases the elastic potential energy to pull the spray washing box 20 to slide in the capture box 8, the spray washing box 20 sprays sewage through the water outlet to realize the overall flushing of the interception plate 14, and the spray washing box 20 attracts the cleaning block 10 through magnetic force, the cleaning block 10 is scraped off the suspended solids on the interception plate 14 when it slides, further improving the cleaning effect, the suspended solids washed off fall into the filtering box 3 for collection; the continuous and efficient treatment of the suspended solids in the sewage is realized, and the quality of sewage treatment is guaranteed.
