The stirring blades 211 of the upper turntable 21 and the lower turntable 22 are adjusted by an angle, when the upper turntable 21 is close to or far from the lower turntable 22 along the axial direction, the distance between the upper turntable 21 and the lower turntable 22 can be changed, and at the moment, the stirring blades 211 on the upper turntable 21 and the lower turntable 22 are synchronously adjusted, for example, when the distance between the upper turntable 21 and the lower turntable 22 is reduced, the stirring blades 211 are far away from one sides of the upper turntable 21 and the lower turntable 22, so that the stirring blades 211 are unfolded, the radial shearing force on the wastewater is increased, the filtration of the wastewater is accelerated, and the interception effect of impurities in the wastewater is enhanced;
when the distance between the upper turntable 21 and the lower turntable 22 is increased, the stirring blades 211 are close to one sides of the upper turntable 21 and the lower turntable 22, so that the stirring blades 211 are folded, the axial plug flow effect is enhanced, and the mixing uniformity of the flocculant and the wastewater is improved through the generated axial circulation flow, so that the flow field form of the device can be dynamically adjusted under different volume states.

As shown in fig. 2, 4-6, 9 and 10, stirring blades 211 of an upper rotary table 21 are rotatably connected with the upper rotary table, first sliding rails 212 which are the same as the stirring blades 211 in number and in one-to-one correspondence are arranged on the upper rotary table 21, the first sliding rails 212 are obliquely arranged, first sliding blocks 2121 which are in sliding fit with the first sliding rails 212 are arranged on the first sliding rails 212, a connecting rod 2122 is arranged between the first sliding blocks 2121 and the stirring blades 211, and two ends of the connecting rod 2122 are respectively hinged with the first sliding blocks 2121 and the stirring blades 211.
When the distance between the upper turntable 21 and the lower turntable 22 is reduced or increased, the first sliding block 2121 slides along the first sliding rail 212, so that the connecting rod 2122 can pull the stirring blade 211 hinged with the first sliding block 2121, and the stirring blade 211 can rotate around the connecting point of the stirring blade 211 and the upper turntable 21, and therefore the angle of the stirring blade 211 is adjusted through the reciprocating sliding of the first sliding block 2121 on the first sliding rail 212.
When the distance between the upper rotary disk 21 and the lower rotary disk 22 is smaller, the stirring blades 211 are far away from one sides of the upper rotary disk 21 and the lower rotary disk 22, so that the stirring blades 211 are unfolded, radial shearing force on waste water is increased, the filtering speed of the waste water passing through the filter screen 23 is accelerated by matching with the volume shrinkage of the filter cavity 2, when the distance between the upper rotary disk 21 and the lower rotary disk 22 is larger, the stirring blades 211 are close to one sides of the upper rotary disk 21 and the lower rotary disk 22, the stirring blades 211 are folded, the axial plug flow effect is enhanced, and the flocculant and the waste water are fully mixed in a larger range by the generated axial circulation flow.
As shown in fig. 2, 4 to 6, 9 and 10, the top of the upper turntable 21 is further provided with a driving disc 213 rotatably connected with the upper turntable and a first rotary driving motor 2131 for driving the driving disc 213 to rotate, the driving disc 213 is provided with a second sliding rail 2132 corresponding to the first sliding rail 212, the second sliding rail 2132 extends along the radial direction of the driving disc 213, and the first sliding block 2121 is simultaneously slidingly matched with the second sliding rail 2132.
The first rotary drive motor 2131 rotates the drive plate 213 about the axis of the upper turntable 21. Because the second slide rail 2132 on the driving disc 213 extends along the radial direction, and the first slide block 2121 is in sliding fit with the first slide rail 212 and the second slide rail 2132 at the same time, the first slide rail 212 is in inclined arrangement, so that the first slide block 2121 can slide under the cross constraint of the first slide rail 212 and the second slide rail 2132, and further drives the connecting rod 2122 connected with the first slide block 2121, and the stirring blade 211 is pulled or pushed by the connecting rod 2122 to rotate around the rotating joint of the stirring blade 211 and the upper turntable 21, so that dynamic adjustment of the angle of the stirring blade 211 is realized.
The rotation of the driving plate 213 can be flexibly adjusted through the first rotary driving motor 2131 according to the treatment requirement, so that the precise control of the angle change amplitude and the response speed of the stirring blade 211 is realized, and the equipment can adapt to wastewater treatment scenes with different concentrations and different impurity contents.
As shown in fig. 2, 4, 5 and 7-10, the stirring blades 211 of the lower rotating disc 22 are rotatably connected with the stirring blades 211, a third sliding rail 221 and a second sliding block 2211 capable of being slidably arranged on the third sliding rail 221 are arranged on the stirring blades 211, a first electric push rod 222 capable of extending and contracting along the vertical direction is arranged below the stirring blades 211 on the lower rotating disc 22, and the first electric push rod 222 is hinged with the second sliding block 2211.
The lower rotary table 22 rotates around the axis of the reaction barrel 1, the first electric push rod 222 stretches and contracts in the vertical direction to drive the second sliding block 2211 to slide on the third sliding rail 221 of the stirring blade 211, and the stirring blade 211 swings around the connecting point of the stirring blade 211 and the lower rotary table 22 due to the fact that the stirring blade 211 is rotationally connected with the lower rotary table 22 and the sliding of the second sliding block 2211 enables the stirring blade 211 to swing around the connecting point of the stirring blade 211 and the lower rotary table 22, so that the angle adjustment of the stirring blade 211 is achieved. When the distance between the upper turntable 21 and the lower turntable 22 changes, the telescopic travel of the first electric push rod 222 is synchronously adapted, so that the angle of the stirring blade 211 of the lower turntable 22 and the stirring blade 211 of the upper turntable 21 cooperatively change, and a dynamic flow field is constructed in the filter cavity 2 in cooperation with the reverse rotation of the upper turntable 21 and the lower turntable 22. Therefore, the precise adjustment of the angle of the stirring blade 211 is realized, the treatment requirements of different water qualities are adapted, the angle of the stirring blade 211 of the lower turntable 22 and the angle of the stirring blade 211 of the upper turntable 21 are cooperatively changed, the flow field in the filter cavity 2 is more symmetrical, and the mixing effect of the flocculant and the wastewater is enhanced. The surface of the filter screen 23 can be disturbed by the angle change of the stirring blade 211, so that the blockage of impurities is reduced, and the service life of the filter screen 23 is prolonged.
It should be noted that the first electric push rods 222 rotate synchronously with the lower turntable 22, and the plurality of first electric push rods 222 are electrically connected with an external power source through a slip ring, so as to allow the lower turntable 22 to rotate continuously without interrupting the power supply.
As shown in fig. 1 to 4, 8 and 9, a driving shaft 11 for driving an upper rotary table 21 to rotate is arranged at the top of a reaction barrel 1, a telescopic driving shaft 12 connected with the driving shaft 11 is arranged on a lower rotary table 22, first bevel gears 121 are arranged at one ends of the driving shaft 11 and the driving shaft 12, which are close to each other, and a second bevel gear 122 in meshed connection with the two first bevel gears 121 is arranged between the two first bevel gears 121.
The top of the driving shaft 11 is provided with a second rotary driving motor 111 for driving the driving shaft 11 to rotate, and after the second rotary driving motor 111 is started, the driving shaft 11 rotates around the axis of the reaction barrel 1, and power is transmitted to the transmission shaft 12 of the lower turntable 22 through the engagement of a first bevel gear 121 at the end part of the driving shaft 11 and a second bevel gear 122 in the middle. The other first bevel gear 121 at the end of the transmission shaft 12 is in a meshed state with the second bevel gear 122, and even if the transmission shaft 12 stretches and contracts with the change of the distance between the upper turntable 21 and the lower turntable 22, the tooth surface contact of the first bevel gear 121 still ensures continuous power transmission, and drives the lower turntable 22 and the upper turntable 21 to realize reverse rotation. The problem of slipping and wearing of the traditional belt or chain transmission in high-speed rotation is avoided, and the reliability of the equipment in long-term operation is improved. The telescopic function of the transmission shaft 12 ensures that the upper rotary table 21 and the lower rotary table 22 can still keep the synchronism of reverse rotation when relatively approaching or separating, ensures that the stirring blades 211 in the filter cavity 2 continuously form opposite-flushing shear flow, and strengthens the mixing effect of wastewater and flocculant. In addition, the transmission structure saves the internal space of the reaction barrel 1, has high transmission efficiency and low noise, is suitable for corrosion and vibration working conditions in the fluorine-containing wastewater treatment environment, and reduces equipment maintenance cost.
The drive shaft 11 is also of a telescopic structure, and the upper turntable 21 is matched to slide along the axial direction of the reaction chamber 1 by the telescopic structure.
As shown in fig. 2, 4, 5 and 7 to 10, the lower turntable 22 has a conical structure, a discharge opening 223 is formed in the center of the lower turntable 22, and a discharge channel 13 corresponding to the discharge opening 223 is formed in the reaction tub 1.
The conical structure of the lower rotary disc 22 enables impurities trapped inside the filter screen 23 after filtration to naturally gather towards the discharge opening 223 in the center of the rotary disc under the combined action of gravity and rotational centrifugal force of the stirring blade 211, and when the upper rotary disc 21 approaches the lower rotary disc 22 to compress the volume of the filter cavity 2, the extrusion action further pushes the impurities to gather towards the discharge opening 223 and discharge the impurities through the corresponding discharge channel 13 on the reaction barrel 1. Avoiding the accumulation of impurities on the surface of the turntable.
The conical structure of the lower rotary table 22 optimizes the movement track of the impurities by utilizing the geometric characteristics, reduces the risk of manual intervention and blockage of the filter screen 23, improves the solid-liquid separation efficiency, and realizes continuous discharge of the filtered impurities by the corresponding arrangement of the discharge opening 223 and the discharge channel 13, adapts to an automatic treatment process and avoids shutdown cleaning. A solenoid valve may be provided on the discharge channel 13 to better handle the discharge time while ensuring the filtering and mixing effect of the waste water when the volume of the filter chamber 2 is changed.
As shown in fig. 2 to 6, 9 and 10, the top of the upper turntable 21 is provided with a lifting disk 14 rotatably connected thereto, and the lifting disk 14 is provided with a plurality of second electric pushrods 141 fixedly connected to the top of the reaction tub 1.
The second electric push rod 141 drives the lifting disk 14 to move up and down along the axial direction of the reaction barrel 1 through telescopic action, and the upper rotary disk 21 can still rotate freely around the own axis while moving along with the lifting disk 14 due to the rotary connection of the lifting disk 14 and the upper rotary disk 21. Thereby, the controllable lifting of the upper rotary table 21 in the rotation process is realized, and the distance between the upper rotary table 21 and the lower rotary table 22 can be precisely controlled by adjusting the telescopic travel of the second electric push rod 141, so that the volume of the filter cavity 2 is changed. Through the linkage of the second electric push rod 141 and the lifting disc 14, the rotation and the lifting motion of the upper rotary disc 21 are decoupled, the accurate control of the volume change of the filter cavity 2 is realized, and the adaptability of the equipment to different treatment stages is improved. In the mixing stage, the larger spacing is matched with the folding angle of the stirring blades 211, the axial circulation flow is strengthened, the flocculant and the wastewater are promoted to be fully mixed, and in the filtering stage, the smaller spacing is combined with the unfolding angle of the stirring blades 211, the radial shearing force is increased, and the impurity interception and discharge are accelerated. The structure is convenient for subsequent installation and maintenance of equipment, the independent control of the second electric push rod 141 provides an interface for subsequent intelligent upgrading, and the volume and stirring parameters of the filter cavity 2 can be automatically adjusted according to water quality monitoring data, so that the treatment effect is optimized.
As shown in fig. 2 to 6, 9 and 10, a feeding cavity 15 is arranged in the center of the lifting disk 14, the feeding cavity 15 is rotationally connected with the upper rotary disk 21, a feeding channel 151 communicated with the inside of the filter cavity 2 is arranged in the feeding cavity 15, and a water inlet pipeline 152 connected with the feeding channel 151 is arranged at the top of the feeding cavity 15.
The inlet channel 152 conveys the wastewater and the flocculant to the top of the feeding cavity 15, and because the feeding cavity 15 is rotationally connected with the upper rotary table 21 and is fixed in the center of the lifting disc 14, the feeding cavity 15 does not rotate along with the upper rotary table 21, only the upper rotary table 21 rotates around the feeding cavity 15, the distortion and abrasion risks caused by the rotation of the inlet channel 152 along with the upper rotary table 21 are avoided, and the feeding continuity and stability are ensured. The waste water and the flocculating agent vertically fall into the central area of the filter cavity 2 through the feeding channel 151 in the feeding cavity 15, so that the centrifugal splashing problem caused by the rotation of the upper turntable 21 is avoided, and meanwhile, the rotation of the upper turntable 21 drives the stirring blades 211 to form vortex under the outlet of the feeding channel 151, so that the material just entering the filter cavity 2 is rapidly involved into the opposite shearing flow field, and the dispersion and the mixing are accelerated.
The central arrangement of the feeding channel 151 enables the materials to directly enter the core area of the flow field, shortens the mixing path, and can realize efficient mixing of the medicament and the wastewater by matching with dynamic angle adjustment of the stirring blade 211. In addition, the structure separates the feeding system from the rotating part, reduces the mechanical coupling complexity, is convenient for independently maintaining the feeding channel 151, improves the overall reliability of the equipment, and is particularly suitable for fluorine-containing wastewater treatment scenes with high impurity content.
A sensor for detecting the interval between the upper rotary disk 21 and the lower rotary disk 22 is provided in the filter chamber 2.
When the distance between the upper turntable 21 and the lower turntable 22 is changed due to the lifting motion, a sensor (not shown) captures distance data in real time through a sensing element, and a control system at the rear end automatically adjusts the rotation angle of the stirring blade 211 and the volume of the filter chamber 2 according to preset parameters. For example, when the spacing is reduced to a filtering threshold, the sensor triggers the stirring vane 211 to be unfolded in angle to strengthen the radial shearing force, and when the spacing is increased to a mixing threshold, the sensor instructs the stirring vane 211 to be folded in angle to strengthen the axial circulation flow.
The sensor realizes accurate monitoring and intelligent regulation of the operation parameters of the equipment, avoids hysteresis and errors of manual intervention, and enables the cooperative matching among all the components to be more efficient. Simultaneously, the early warning function of the sensor can prevent mechanical collision caused by excessive approaching of the upper rotary table 21 and the lower rotary table 22, protect the flexible filter screen 23 and the stirring mechanism, and prolong the service life of the equipment.
The above examples merely illustrate one or several embodiments of the present invention, which are described in more detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of the invention should be assessed as that of the appended claims.
