All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 11, a filtering mechanism for sewage treatment of the present invention includes a first connection pipe 1 and a second connection pipe 7, the first connection pipe 1 and the second connection pipe 7 being connected to sewage pipes, respectively. The filtering mechanism also comprises a shunt tube 3, a crushing tube 4 and a storage tube 6 which are sequentially positioned between the first connecting tube 1 and the second connecting tube 7; the first connecting pipe 1 is internally provided with a first filter tank 2, and the accommodating pipe 6 is internally provided with a second filter tank 5 and a flow sensor 8.
When in use, the filter structure needs to be connected into a sewage pipeline. The filtering mechanism is vertically or obliquely arranged, and the first connecting pipe 1 and the second connecting pipe 7 are respectively connected into a sewage pipeline, so that sewage can flow in from the first connecting pipe 1 and flow out from the second connecting pipe 7. The sewage flows through the first filter tank 2 and the second filter tank 5 in sequence, and can be filtered.
A plurality of shunt arc pieces 301 are uniformly arranged in the shunt tube 3, the shunt arc pieces 301 are obliquely arranged, and the inclination angle is adjustable, so that the shunt tube 3 is divided into a plurality of areas; a plurality of rotary cutters 401 are uniformly arranged in the crushing pipe 4 at the positions corresponding to the diversion arc pieces 301, and the cutting edges of the rotary cutters 401 are upward and can rotationally cut under the action of water flow.
The shunt arc piece 301 comprises an arc piece body 302, an adjusting shaft 303 and a control motor 304, wherein the adjusting shaft 303 is positioned at the upper end of the arc piece body 302, the adjusting shaft 303 is transversely arranged along the section of the shunt tube 3 and penetrates through the side wall of the shunt tube 3, and the control motor 304 is connected with the tail end of the adjusting shaft 303; the inner wall of the crushing pipe 4 is connected with a movable gear ring 402 along the circumferential direction, the tail part of each rotary cutter 401 is coaxially provided with a synchronous gear 403, and a plurality of synchronous gears 403 are meshed with the movable gear ring 402.
After the flow sensor 8 is installed in the second filtering tank 5, the flow sensor 8 monitors the flow passing through the storage pipe 6 in real time and transmits flow data to the control unit 9, and the control unit 9 sends out an operation command to enable the control motor 304 to operate according to the flow change in the pipeline, so that the inclination angle of the shunt arc piece 301 is adjusted.
As shown in fig. 2, 3 and 4, the upper end edge of the first connecting pipe 1 is symmetrically provided with a fitting groove 104; the first filter tank 2 comprises a fitting block 201 and a first filter screen 202; the attaching blocks 201 are symmetrically arranged on two sides of the upper end surface of the first filter tank 2, the attaching blocks 201 are in an inverted U-shaped structure, and are just clamped into the attaching tank 104; the first filter screen 202 is disposed at the bottom center of the first filter tank 2.
The first filter 202 is mainly used for primarily filtering sewage and filtering and isolating impurities with larger volume. Meanwhile, the first filter tank 2 and the first connecting pipe 1 are respectively provided with the attaching block 201 and the attaching groove 104, so that the first filter tank 2 is conveniently fixed and can be quickly detached, and the first filter tank 2 and the first connecting pipe are mutually movable, so that large sundries or garbage can be isolated, and the primary filtering capacity of sewage is improved.
With continued reference to fig. 3, adjusting grooves 103 are symmetrically formed on both sides of the first connecting tube 1, connecting seats 107 and screw seats 102 are fixed on the sides of the adjusting grooves 103, through holes 108 are formed in the connecting seats 107 and the screw seats 102, and locking structures 10 are arranged on the through holes 108. When the first connecting pipe 1 is connected with the sewage pipeline, the pipeline is aligned and the locking structure 10 is locked, so that the gap of the adjusting groove 103 can be reduced, the butt joint of the pipeline is completed rapidly, and the installation stability of the whole filtering mechanism is ensured.
In this embodiment, the locking structure 10 includes a limit groove 106, a nut 105 and a screw 101, the limit groove 106 is formed on the outer side of a through hole 108 on the screw seat 102, one side of the nut 105 is tightly attached to the limit groove 106, and the screw 101 passes through the connecting seat 107 and the through hole 108 on the screw seat 102 to be in threaded connection with the nut 105. The nut 105 and the bolt are mutually rotated and tightened, so that the gap of the adjusting groove 103 can be changed, and the first connecting pipe 1 can be locked on the sewage pipeline, and the installation is quick and convenient.
Of course, in order to allow a quick installation of the entire filter mechanism, a locking structure 10 may also be provided at the end of the second connecting tube 7.
As shown in fig. 5, a plurality of shunt arc pieces 301 are uniformly arranged in the shunt tube 3, and the shunt arc pieces 301 are obliquely arranged to divide the shunt tube 3 into a plurality of areas; a plurality of rotary cutters 401 are uniformly arranged in the crushing pipe 4 at the positions corresponding to the diversion arc pieces 301. The plurality of shunt arcs 301 divide the cross section of the shunt tube 3 into a plurality of areas and direct the water flow to flow in different areas and directions and to the crushing tube 4 in a relative movement with the corresponding shear blades 401. While the water flow and the rotary cutter 401 generate relative motion, sundries or particles with larger volume in the water body are cut into particles with smaller volume by the rotary cutter 401, and the particles continue to flow forwards. The diversion arc piece 301 also plays a certain stirring role on sundries or particles in water flow when diverting, so that the sundries or particles can uniformly enter the crushing pipe 4 for crushing.
The shunt arc 301 comprises an arc body 302, an adjusting shaft 303 and a control motor 304, wherein the adjusting shaft 303 is positioned at the upper end of the arc body 302, the adjusting shaft 303 is transversely arranged along the section of the shunt tube 3 and penetrates through the side wall of the shunt tube 3, and the control motor 304 is connected with the tail end of the adjusting shaft 303. When the motor 304 is controlled to act, the adjusting shaft 303 is driven to rotate, so that the arc piece body 302 rotates, and the angle of the whole shunt arc piece 301 is adjusted. After the angle of the diversion arc piece 301 is adjustable, the water flow direction is correspondingly changed, and the cutting effect of the rotary cutter 401 can be changed, so that the cutting and crushing functions of the whole device are more diversified.
As shown in fig. 9, in order to ensure the sealing between the adjusting shaft 303 and the shunt tube 3, a sealing bearing 304 is mounted on the adjusting shaft 303 at the side wall penetrating through the shunt tube 3, and the outer edge of the sealing bearing 304 is fixedly connected with the shunt tube 3.
As is well known, the rotary cutter 401 cuts the sundries or the particles by the rotation of the blade. Thus, we can use external energy or natural force to rotate, for example, to configure the rotary cutter 401 with a rotary motor and energize. In this example, with the diversion of the diversion arc piece 301, we can drive the rotation cutter 401 to rotate naturally by the impact of water flow. We will rotate the cutting blade 401 upwards and can cut by the water flow. In this way, the water flow drives the rotary cutter 401 to rotate, so as to cut the impurities or particles with larger volume in the water body, and fully filter the sewage.
The inner wall of the crushing pipe 4 is connected with a movable gear ring 402 along the circumferential direction, the tail part of each rotary cutter 401 is coaxially provided with a synchronous gear 403, and a plurality of synchronous gears 403 are meshed with the movable gear ring 402. Since the plurality of synchronizing gears 403 are meshed with the movable gear ring 402, the movable gear ring 402 drives the synchronizing gears 403 to move while the synchronizing gears 403 drive the movable gear ring 402 to move. When one of the rotary cutter 401 and the synchronizing gear 403 rotates, the other rotary cutter 401 is also synchronized with the rotation speed of the rotary cutter 401. Therefore, even if the water flow in the pipe is not uniform or the sizes of the sundries are different, a good crushing effect can be obtained when the sundries are crushed by the rotary cutter 401 through the crushing pipe 4.
Further, as shown in fig. 10, an adjusting rod 404 is arranged outside the movable gear ring 402, and the adjusting rod 404 penetrates through the pipe wall of the crushing pipe 4 and is hinged with the crushing pipe 4. The adjusting rod 404 is hinged with the crushing tube 4 and can rotate up and down to drive the movable gear ring 402 to move up and down in the crushing tube 4. While moving, the movable gear ring 402 is meshed with or separated from the synchronous gear 403, so that the linkage of the plurality of rotary cutters 401 is more free and flexible.
Preferably, in order to fully perform the splitting, stirring and cutting actions of the splitting arc 301 and the rotary cutter 401, the number of the splitting arc 301 and the rotary cutter 401 is three.
As shown in fig. 11, the flow sensor 8 monitors the flow through the receiving pipe 6 in real time, and transmits flow data to the control unit 9, and the control unit 9 sends an operation command to operate the control motor 304 according to the flow change in the pipe, thereby adjusting the inclination angle of the shunt arc 301. When the flow sensor 8 monitors that the flow of the storage tube 6 is reduced and abnormal, flow data are transmitted to the control unit 9, the control unit 9 sends out an operation command to enable the control motor 304 to operate, the adjusting shaft 303 is driven to rotate, the inclination angle of the split arc piece 301 is reduced, water flow is accelerated to enter the crushing tube 4 through the split tube 3, the rotary cutter 401 is driven to accelerate cutting, sundry particles are better cut and crushed, and accordingly the flow of the storage tube 6 is increased, and the flow passing through the whole filtering mechanism is normal. When the flow sensor 8 detects that the flow of the storage tube 6 is abnormal, the control unit 9 issues an opposite instruction. In a word, the flow sensor 8 and the control motor 304 operate under the control of the control unit 9 to drive other components to act, so that the whole device can normally operate.
As shown in fig. 6 and 7, a transfer hole 605 is formed in the side surface of the storage tube 6, a movable sealing door 603 is mounted on the transfer hole 605, the movable sealing door 603 can move along the circumferential direction of the storage tube 6, a push block 601 is mounted on one side of the movable sealing door 603, and a protrusion 602 is arranged on the push block 601; the lower end of the receiving tube 6 is also fixed with a rest net 604, and the second filter tank 5 is mounted on the rest net 604. The resting net 604 plays a fixed role for the second filter tank 5.
The second filter tank 5 comprises an annular side wall 501 and a second filter screen 502 connected with the bottom end of the side wall 501, a filter sheet 503 is paved on the second filter screen 502, and a hand-held block 504 is arranged on the outer side of the side wall 501. Meanwhile, in order to improve the filtering effect, the filter sheet 503 may be laid in multiple layers.
In order to facilitate the replacement of the second filter screen 502, the second filter tank 5 is movably connected with the receiving tube 6. Therefore, a transfer hole 605 is formed in the side surface of the storage tank. In order to smoothly take out the second filtering tank 5, the width of the transfer hole 605 is equal to or greater than the semicircular circumference of the receiving pipe 6. Since the movable seal door 603 is used for a sewage pipe, it is necessary to install the movable seal door 603 in the transfer hole 605. The shape of the movable sealing door 603 matches the shape of the transfer hole 605 and has a size larger than the size of the transfer hole 605. Sliding structures are arranged between the upper end and the lower end of the movable sealing door 603 and the transfer holes 605. The sliding structure may be a sliding groove fixed on the transfer hole 605, into which the upper and lower ends of the movable sealing door 603 are inserted. As shown in fig. 8, a seal 606 is provided between the movable seal door 603 and the transfer hole 605 for sealing. Sealing strip 606 mainly plays a role in isolation and sealing, and the material of sealing strip 606 can be selected according to actual needs.
The push block 601 and the bulge 602 are arranged on the movable sealing door 603, and the handheld block 504 is arranged on the second filter tank 5, so that the movable sealing door 603 and the second filter tank 5 can be conveniently moved, and the purpose of quickly replacing the second filter screen 502 is achieved.
It should be noted that, in order to obtain a better filtering effect, the accuracy of the second filter 502 is higher than that of the first filter 202. Typically, the first filter tank 2 is a stainless steel punched filter screen with a pore size of 2-5mm, and the second filter tank 5 is a stainless steel woven filter screen with a pore size of 0.5-2 mm.
The working principle of the filtering mechanism is as follows:
1. and (3) device installation: attaching the attaching block 201201 to the attaching groove 104104 to complete the installation of the first filter tank 2; the second filter tank 5 is arranged in the containing pipe 6, and the movable sealing door 603 is closed; aligning the first connecting pipe 1 and the second connecting pipe 7 with the sewage pipelines respectively, and adjusting the locking structure 10 to finish the connection of the first connecting pipe 1 and the second connecting pipe 7 with the sewage pipelines respectively;
2. and (3) filtering: the sewage passes through the first filter tank 2, and a large volume of sundries are filtered, so that preliminary filtration is realized; the sewage enters the shunt tube 3 and the crushing tube 4, and under the action of the shunt arc piece 301 and the rotary cutter 401, sundries and particles with larger volumes are cut and crushed; finally, sewage enters a storage pipe 6, large particles are filtered by a second filter tank 5, and the filtering treatment is completed; in the filtering process, when the flow sensor 8 monitors that the flow of the storage tube 6 is abnormal, flow data are transmitted to the control unit 9, the control unit 9 sends out an operation command to enable the control motor 304 to operate according to the flow change in the pipeline, the adjusting shaft 303 is rotated, the inclination angle of the split arc piece 301 is adjusted, and therefore the cutting and crushing effect of the rotary cutter 401 is changed, and the filtering effect is improved;
3. and (3) replacing a filter screen: directly opening the movable sealing door 603, taking out the second filter tank 5, and replacing the second filter screen 502; the first connection pipe 1 is disconnected from the sewage pipe, and the first filter tank 2 is removed to replace the first filter screen 202.
In summary, by arranging the first filter screen 202 and the second filter screen 502 in the filtering mechanism, impurities in sewage can be sufficiently filtered by the two filter screens, so that the filtering effect is better, meanwhile, by arranging the split arc piece 301 in the split water pipe, water flow can be split, and then garbage in the water flow can be crushed by matching with the rotary cutter 401 arranged in the crushing pipe 4, and the sewage treatment capacity of the whole device can be increased; meanwhile, the locking structure 10 can be quickly connected with the sewage pipeline, the locking structure 10 can be adjusted to drive the adjusting groove 103 to quickly tighten, so that the stable connection capability between the sewage pipeline and the filtering mechanism can be adjusted, and the stable installation capability of the whole filtering mechanism can be further improved.
