For the convenience of description, the sewage to be treated is denoted as external sewage, the treated sewage is denoted as clean water, and the washing water containing a large amount of impurities after backwashing is denoted as washing sewage.
[0023] Reference Signs List Figure 1The concave-convex deformation resonance type backwashing stainless steel filter tank of the present application comprises a protective shell 10, two double-cone filter tanks 11 rotatably arranged inside the protective shell 10 by means of collinear rotating shafts A41 and B42 at two sides, respectively, a busbar 6 fixedly arranged on the rotating shaft A41, two resonant filter screens 21 of the same structure arranged inside the double-cone filter tank 11, a vibration exciting assembly 3 for exciting the resonance of the resonant filter screen 21, a vibration spring 22 connected to the center points of the two resonant filter screens 21 at two ends, respectively, a filter screen deformation driving assembly for driving the resonant filter screen 21 to deform concave-convex, a vibration driving device for driving the vibration exciting assembly 3 to work, and a turnover motor 43 for driving the rotating shaft B42 to rotate in the forward and reverse directions. In the specific implementation, the left end of the rotating shaft A41 is rotatably arranged on the left side plate of the protective shell 10 by means of a rolling bearing, and the right end thereof is fixedly connected to the middle part of the left outer wall of the double-cone filter tank 11; the left end of the rotating shaft B42 is fixedly connected to the middle part of the right outer wall of the double-cone filter tank 11, and the right end thereof is rotatably arranged on the right side plate of the protective shell 10 by means of another rolling bearing; the turnover motor 43 is fixedly arranged on the outer wall of the protective shell 10, and the output shaft thereof is drivingly connected to the right end of the rotating shaft B42. The collinear rotating shafts A41 and B42 are arranged along the horizontal direction, and are in-plane orthogonal to the axis of the double-cone filter tank 11 along the vertical direction. The two resonant filter screens 21 and the two vibration exciting assemblies 3 are symmetrically arranged up and down about the collinear rotating shafts A41 and B42, and the two resonant filter screens 21 are arranged as concave or as convex by means of the vibration spring 22.
[0024] The double-cone filter tank 11 comprises a hollow cylinder and conical heads A and B fixedly connected to both ends of the hollow cylinder; the conical head A and the upper resonant filter screen 21 form a filter cavity A, the blowdown pipe A 12, the water inlet pipe A 14 and the water outlet pipe A (not shown in the figure) are communicated with the filter cavity A through the conical head A, the conical head B and the lower resonant filter screen 21 form a filter cavity B, the blowdown pipe B 13, the water inlet pipe B 15 and the water outlet pipe B (not shown in the figure) are communicated with the filter cavity B through the conical head B; the water inlet channel (not shown in the figure), the sewage channel (not shown in the figure) and the water outlet channel (not shown in the figure) are arranged on the water collecting plate 6, the water inlet channel is communicated with the water inlet pipe A 14, the water inlet pipe B 15 and the total water inlet pipe 62, the sewage channel is communicated with the blowdown pipe A 12, the blowdown pipe B 13 and the total blowdown pipe 61, and the water outlet channel (not shown in the figure) is communicated with the water outlet pipe A (not shown in the figure), the water outlet pipe B (not shown in the figure) and the total water outlet pipe (not shown in the figure). In specific implementation, a valve independently controlled is arranged on each pipe to open or close the corresponding pipe. In order to improve the backwashing effect and avoid the secondary pollution of clean water by backwashing, the blowdown pipe A 12 and the blowdown pipe B 13 are arranged at the tip of the conical head A and the conical head B respectively. In specific use, the external sewage flows into the water collecting plate 6 through the total water inlet pipe 62, flows into the filter cavity A or the filter cavity B through the water inlet pipe A 14 or the water inlet pipe B 15 and the upper resonant filter screen 21 through the water inlet channel, the clean water enters the filter cavity B or the filter cavity A through the lower resonant filter screen 21, flows out to the external clean water equipment through the water outlet pipe A or the water outlet pipe B, the water outlet channel and the total water outlet pipe, and the flushing sewage flows out to the external blowdown equipment through the blowdown pipe A 12 or the blowdown pipe B 13, the sewage channel and the total blowdown pipe 61. The double-cone filter tank 11 is driven by the overturning motor 43 to be overturned by 180° in the forward direction or the reverse direction, and the position of the conical head A and the conical head B is exchanged, that is, the position of the two resonant filter screens 21 is exchanged. In order to avoid the water pipes inside the protective shell 10 from being wound, the double-cone filter tank 11 is always overturned by 180° in the forward direction and the reverse direction alternately. Through the control of the independent valve on the water pipe, the external sewage flows into the double-cone filter tank 11 through the total water inlet pipe 62 and flows downward in the double-cone filter tank 11, that is, the external sewage always flows from the resonant filter screen 21 at the higher position to the resonant filter screen 21 at the lower position, so the impurities in the external sewage are always intercepted on the upper surface of the resonant filter screen 21 at the higher position. When the resonant filter screen 21 with impurities on the surface needs to be flushed, the overturning motor 43 first drives the double-cone filter tank 11 to be overturned by 180°, the position of the two resonant filter screens 21 is exchanged, so that the impurities are transferred from the upper surface of the resonant filter screen 21 at the higher position to the lower surface of the resonant filter screen 21 at the lower position.
[0025] Referring to Figure 1 and Figure 4, the resonant filter screen 21 comprises a fixed ring 211, a curved filter screen 212 which can be deformed concave-convex inside the fixed ring 211, and a plurality of resonators 213 which are distributed equidistantly along the circumference and are arranged on the curved filter screen 212. In the specific implementation, the fixed ring 211 is arranged on the inner side surface of the double-cone filter tank 11; the resonators 213 are solid stainless steel balls, which are used to increase the local inertial mass of the resonant filter screen 21, to reduce the natural vibration frequency, and to further improve the vibration effect of the curved filter screen 212; the resonators 213 are made of stainless steel material, which avoids secondary pollution to the clean water; and the curved filter screen 212 is a flexible spherical curved screen which can be deformed concave-convex.
[0026] Referring to Figure 1 and Figure 3 , the excitation assembly 3 is arranged in one-to-one correspondence with the resonant filter screen 21; the excitation assembly 3 comprises an excitation rod 31 which is hingedly arranged at one end on the inner side wall of the double-cone filter tank 11 and is provided at the other end with an excitation ball 32, an energy storage spring 33 which is fixedly connected at both ends to the excitation rod 31 and the inner side wall of the double-cone filter tank 11, and a traction rope C 34 which is connected at one end to the excitation rod 31 and is fixed at the other end around the fixed pulley set A and on the outer side wall of the double-cone filter tank 11. In the specific implementation, the fixed pulley set A comprises a fixed pulley A 35 which is rotatably arranged on the inner side wall of the double-cone filter tank 11, and a fixed pulley B 36 and a fixed pulley C 37 which are rotatably arranged on the outer side wall of the double-cone filter tank 11; one end of the traction rope C 34 is connected to the excitation rod 31, and the other end is wound around the fixed pulley A 35, passes through a threading hole C provided on the side wall of the double-cone filter tank 11, is wound around the fixed pulley B 36 and the fixed pulley C 37, and is then fixedly connected to the outer wall of the double-cone filter tank 11. When the lower traction rope C 34 is stretched, the lower excitation rod 31 rotates counterclockwise around the hinge point, the deformation amount of the energy storage spring 33 increases, and the elastic potential energy is accumulated; when the lower traction rope C 34 is suddenly released, the lower excitation rod 31 rotates clockwise under the action of the spring force of the energy storage spring 33, so that the lower excitation ball 32 impacts the lower resonant filter screen 21, and the lower resonant filter screen 21 compresses the excitation spring 22 upward, at this time, since the upper end of the excitation spring 22 is temporarily fixed, the excitation spring 22 absorbs the excitation vibration energy of the excitation ball 32 through compression deformation, and then releases the vibration energy through the slight vibration of the lower curved filter screen 212. Such slight vibration can make the impurities quickly fall off from the lower curved filter screen 212 and flow into the total sewage pipe 61 under the action of the reverse flushing.
[0027] Referring to Figure 1 and Figure 2The filter screen deformation driving assembly comprises a winding wheel 25 rotatably arranged on the rotating shaft A41, a winding motor 26 driving the winding wheel 25 to rotate, and a traction rope A23 and a traction rope B24 wound on the winding wheel 25 in opposite directions. The axis of the winding wheel 25 is perpendicular to the axis of the rotating shaft A41, and the other ends of the traction rope A23 and the traction rope B24 pass through a fixed pulley set B and are respectively fixedly connected with the middle portions of the two curved filter screens 212. In specific implementation, a motor plate is fixedly arranged on the rotating shaft A41, the winding motor 26 is fixedly arranged on the motor plate, the winding wheel 25 is fixedly arranged on the output shaft of the winding motor 26, and the output shaft of the winding motor 26 is perpendicular to the rotating shaft A41, so that the axis of the winding wheel 25 is perpendicular to the axis of the rotating shaft A41. The double-cone filter tank 11 is provided with a threading hole A111 and a threading hole B112 on the inner wall of the side close to the winding wheel 25. The fixed pulley set B comprises a fixed pulley D71 and a fixed pulley F73 rotatably arranged on the inner wall of the double-cone filter tank 11, and a fixed pulley E72 and a fixed pulley G74 rotatably arranged on the outer wall of the double-cone filter tank 11. One end of the traction rope A23 is fixedly connected with the curved filter screen 212 close to the conical head A, and the other end of the traction rope A23 is wound on the winding wheel 25 in a forward direction via the fixed pulley D71, the threading hole A111 and the fixed pulley E72. One end of the traction rope B24 is fixedly connected with the curved filter screen 212 close to the conical head B, and the other end of the traction rope B24 is wound on the winding wheel 25 in a reverse direction via the fixed pulley F73, the threading hole B112 and the fixed pulley G74. The winding modes of the traction rope A23 and the traction rope B24 make one of the traction rope A23 and the traction rope B24 in a winding state and the other in a releasing state when the winding wheel 25 rotates.
[0028] Referring to Figure 1 , Figure 3 and Figure 6, as preferably, the vibration exciting power device comprises: a T-shaped pull rod 51 sliding through the protection shell 10 in horizontal direction, a rack 52 fixedly arranged on the longitudinal rod of the T-shaped pull rod 51, a sector gear 53 rotatably arranged inside the protection shell 10 and engaged with the rack 52, an energy storage motor 54 driving the sector gear 53 to rotate, and a protection spring 55 sleeved on the longitudinal rod; the cross rod 511 of the T-shaped pull rod 51 is always located between the traction rope C34 and the outer wall of the double-cone filter tank 11, and the protection spring 55 is fixedly connected to the T-shaped pull rod 51 at the end of the protection shell 10 away from the protection shell 10. As preferably, the overturning motor 43 is a servo motor, the winding motor 26 is a speed reduction motor, and the energy storage motor 54 is a stepping motor. In specific implementation, the number of the vibration exciting power device is one, which is arranged on the protection shell 10 close to the lower vibration exciting assembly 3, so that the T-shaped pull rod 51 can always act on the lower traction rope C34 after the double-cone filter tank 11 is overturned. The energy storage motor 54 drives the sector gear 53 to rotate counterclockwise, when the rack 52 is engaged with the sector gear 53, the cross rod 511 of the T-shaped pull rod 51 pulls the traction rope C34 to the right, so that the lower vibration exciting rod 31 rotates counterclockwise, and the energy storage spring 33 stores energy; when the rack 52 is disengaged from the sector gear 53, the energy storage spring 33 releases energy, the lower vibration exciting rod 31 rotates clockwise, and the vibration ball 32 impacts the lower curved filter screen 26, thereby causing the curved filter screen 26 to vibrate. The protection spring 55 can prevent the T-shaped pull rod 51 from moving too much to the left.
[0029] Referring to Figure 5 , as preferably, the protection shell 10 is provided with an arc-shaped through hole A101 allowing the total sewage pipe 61 to slide therethrough, an arc-shaped through hole B102 allowing the total water inlet pipe 62 to slide therethrough, and an arc-shaped through hole C (not shown in the figure) allowing the total water outlet pipe (not shown in the figure) to slide therethrough. When the double-cone filter tank 11 is overturned in forward and reverse directions, the total sewage pipe 61, the total water inlet pipe 62 and the total water outlet pipe can slide in the corresponding through holes, so as to achieve the effect of rotating synchronously with the busbar 6.
[0030] The working principle of the external sewage filtering of the double-cone filtering tank 11 is as follows: when the conical head A is on the top and the conical head B is on the bottom, at this time, the two curved filtering screens 212 are in concave filtering state; the external sewage flows to the inside of the double-cone filtering tank 11 through the total water inlet pipe 62, the water inlet channel and the water inlet pipe A 14 in turn, the impurities in the external sewage are intercepted in the resonant filtering screen 21 on the top, the clean water flows through the resonant filtering screen 21 on the bottom and then flows out through the water outlet pipe B (not shown in the figure), the water outlet channel (not shown in the figure) and the total water outlet pipe (not shown in the figure) in turn. In the above process, the water inlet pipe B 15, the water outlet pipe A (not shown in the figure) and the total sewage discharge pipe 61 are all in the valve closed state. When the conical head B is on the top and the conical head A is on the bottom, the external sewage to be treated flows to the inside of the double-cone filtering tank 11 through the total water inlet pipe 62, the water inlet channel and the water inlet pipe B 15 in turn, the impurities in the external sewage are intercepted in the resonant filtering screen 21 on the higher position, the clean water flows through the resonant filtering screen 21 on the lower position and then flows out through the water outlet pipe A (not shown in the figure), the water outlet channel (not shown in the figure) and the total water outlet pipe (not shown in the figure) in turn, in the above process, the water inlet pipe A 14, the water outlet pipe B (not shown in the figure) and the total sewage discharge pipe 61 are all in the valve closed state.
[0031] The working principle of the resonant filtering screen 21 realizing the mutual transformation between the convex state and the concave state is as follows: the two resonant filtering screens 21 in the concave state are transformed into the convex state after the double-cone filtering tank 11 is turned over, that is, the transformation of the resonant filtering screen 21 from the concave state to the convex state is realized by turning over the double-cone filtering tank 11. In order to clearly understand the working process of the transformation of the two resonant filtering screens 21 from the convex state to the concave state, it is convenient to describe that the traction rope A 23 is connected with the convex resonant filtering screen 21 on the higher position and the traction rope B 24 is connected with the convex resonant filtering screen 21 on the lower position. The winding motor 26 drives the winding wheel 25 to rotate counterclockwise, the traction rope A 23 starts to wind, and at the same time, the traction rope B 24 starts to release, so the traction rope A 23 pulls the center of the curved filtering screen 212 on the higher position downward, so that the resonant filtering screen 21 on the higher position is transformed from the convex state to the concave state; in the above process, since the two curved filtering screens 212 are connected through the excitation spring 22 and the traction rope B 24 is in the relaxed state, when the center of the curved filtering screen 212 on the higher position moves downward, the excitation spring 22 will push the center of the curved filtering screen 212 on the lower position to move downward, until the resonant filtering screen 21 on the lower position is also transformed from the convex state to the concave state, that is, the transformation of the two resonant filtering screens 21 from the convex state to the concave state is realized by the combined action of the traction rope A 23, the traction rope B 24 and the excitation spring 22.
[0032] The resonant backwashing working principle of the resonant filter screen 21 in the application: in the application, when both of the resonant filter screens 21 are concave, the corresponding state is a concave filtering state or a concave backwashing state, and when both of the resonant filter screens 21 are convex, the corresponding state is an intermediate state from the concave filtering state to the concave backwashing state. Without loss of generality, it is assumed that the resonant filter screen 21 close to the conical head A needs backwashing, that is, the impurities are located on the upper surface of the resonant filter screen 21 at a higher position, that is, both of the resonant filter screens 21 are in the concave filtering state. Figure 1 The resonant filter screen 21 close to the conical head A needs backwashing, that is, the impurities are located on the upper surface of the resonant filter screen 21 at a higher position, that is, both of the resonant filter screens 21 are in the concave filtering state. The first step is to temporarily close all the water pipe valves; the second step is to rotate the motor 43 driving shaft B 42 by 180° to make the double-cone filter tank 11 overturn, that is, the conical head A is at the bottom and the conical head B is at the top. At this time, both of the resonant filter screens 21 are in the convex intermediate state, and the impurities are located on the lower surface of the resonant filter screen 21 close to the conical head A; the third step is to drive the winding wheel 25 to rotate by the winding motor 26, so that both of the resonant filter screens 21 are changed from the convex intermediate state to the concave backwashing state; the fourth step is to open the corresponding valve, so that the external sewage flows into the double-cone filter tank 11 through the total water inlet pipe 62 and the water inlet pipe B 15, and washes the resonant filter screen 21 from top to bottom; at the same time, the vibration exciting device drives the vibration exciting assembly 3 to work, so that the vibration exciting ball 32 impacts the curved filter screen 212 at a lower position, and then causes the curved filter screen 212 at the lower position to vibrate rapidly, the impurities are quickly shaken off from the curved filter screen 212, and flow to the sewage discharge pipe A 12 with the washing sewage, and are discharged through the sewage channel and the total sewage discharge pipe 61; the fifth step is to open the corresponding valve after the washing is completed, so that the continuous filtering can be realized, that is, the resonant filter screen 21 is in the concave filtering state again.
[0033] The above is only a specific embodiment of the application, but the protection scope of the application is not limited thereto, and any change or replacement without creative labor should belong to the protection scope of the application.
