As shown in fig. 1 and 2, the present invention discloses a stirring apparatus 10 suitable for semidry desulfurization, which comprises: filtered water pit 20, fixed base 30, driving mechanism 40 and stirring mechanism 50. Wherein, the fixed base 30 is arranged above the filtered water pit 20, the driving mechanism 40 is arranged on the fixed base 30, and the stirring mechanism 50 is in driving connection with the driving mechanism 40.
Specifically, as shown in fig. 3, the drive mechanism 40 includes: a driving motor 100, a reciprocating elevating assembly 200 and a reciprocating swinging assembly 300.
As shown in fig. 3 and 4, the reciprocating lifting assembly 200 includes a driving drum 210 and a driven telescopic rod 220. The driving rotating drum 210 is in driving connection with the driving motor 100, a lifting driving groove 211 is formed in the driving rotating drum 210, the driven telescopic rod 220 is slidably arranged on the fixed base 30, and a pressing driving column 221 matched with the lifting driving groove 211 is arranged on the driven telescopic rod 220. In the slurry stirring process, the driving motor 100 drives the driving drum 210 to rotate in one direction, and the pressing driving column 221 abutting against the lifting driving groove 211 performs lifting motion along with the rotation of the driving drum 210, so as to drive the driven telescopic rod 220 to perform lifting motion.
In the present embodiment, as shown in fig. 5, the elevation driving groove 211 includes: a lower slot 212, an upper slot 213, and a transition 214. The lower groove 212 and the upper groove 213 are used for keeping the position of the driven telescopic rod 220 unchanged; the transition portion 214 is used for driving the driven telescopic rod 220 to ascend or descend, and further driving the stirring mechanism 50 to ascend and descend.
As shown in fig. 3, 4 and 5, the reciprocating yaw assembly 300 includes a driving turntable 310 and a driven yaw sleeve 320. The driving turntable 310 is fixedly connected to the driving drum 210, the driving turntable 310 is provided with a yaw driving groove 311, the driven yaw sleeve 320 is rotatably provided on the fixed base 30, and the driven yaw sleeve 320 is provided with a yaw thrust pin 321 matched with the yaw driving groove 311. During the slurry stirring process, the driving rotary disk 310 rotates with the driving rotary drum 210, and since the deflection thrust nails 321 on the driven deflection sleeve 320 are accommodated in the deflection driving grooves 311, as shown in fig. 6, the driven deflection sleeve 320 is driven by the driving rotary disk 310 to perform reciprocating rotation, so as to drive the stirring mechanism 50 to perform reciprocating rotation, which will be explained below.
In the present embodiment, as shown in fig. 5, the yaw driving groove 311 includes: small diameter portion 312, large diameter portion 313, and intermediate portion 314. The small diameter part 312 and the large diameter part 313 are used for keeping the position of the driven deflection sleeve 320 unchanged; the middle portion 314 is used for driving the driven deflecting sleeve 320 to deflect, and further driving the stirring mechanism 50 to rotate.
In one embodiment, as shown in fig. 3, the driven telescopic rod 220 is engaged with the fixed base 30 by a shaft key, so that the driven telescopic rod 220 can slide smoothly on the fixed base 30.
As shown in fig. 3, the stirring mechanism 50 includes a stirring rod 400 and a pulse stirring paddle 500. The stirring rod 400 is in driving connection with the driven telescopic rod 220 and the driven deflection sleeve 320, and the pulse stirring paddle 500 is installed on the stirring rod 400.
As shown in fig. 7 and 8, the pulse stirring paddle 500 has an arc-shaped stirring surface 510, a storage tank 520 and a plurality of opening and closing through holes 530 are formed on the pulse stirring paddle 500, the opening and closing through holes 530 are arranged on the arc-shaped stirring surface 510 at intervals, each opening and closing through hole 530 is communicated with the storage tank 520, and an opening and closing door 540 capable of freely rotating is further disposed on each opening and closing through hole 530. During agitation of the slurry, sediment that may be present in the slurry will settle and accumulate in the lower region of the filtered water sump 20 due to the influence of gravity. The stirring mechanism 50 of the present invention has both lifting and rotating motions, and the pulse stirring paddle 500 can be used to pump the slurry in the lower region of the filtered water pit 20 to the upper region in cooperation with the motion of the stirring mechanism 50, so as to achieve the purpose of re-stirring and suspending the solid precipitate, and the specific steps will be described below.
In this embodiment, as shown in fig. 4 and 5, the driven telescopic rod 220 is provided with a connecting rod 222, and one end of the connecting rod 222 is sleeved on the stirring rod 400. Therefore, the stirring rod 400 can perform telescopic movement along with the sliding of the driven telescopic rod 220, and the rotation of the stirring rod 400 does not affect the driven telescopic rod 220.
In the present embodiment, as shown in fig. 5, the driven swing sleeve 320 has an accommodating groove 322, the stirring rod 400 is slidably accommodated in the accommodating groove 322, and the stirring rod 400 is provided with a limit key 420. Thus, the paddle 400 can be rotated by the rotation of the driven swing sleeve 320 and can slide in the receiving groove 322.
The operation principle of the stirring device 10 suitable for semidry desulfurization will be described below with reference to the present embodiment:
in the slurry stirring process, the driving motor 100 drives the driving drum 210 to rotate in one direction, and the lifting driving groove 211 drives the pressing driving column 221 to slide on the fixed base 30 due to the pressing driving column 221 pressing on the lifting driving groove 211, thereby driving the driven telescopic rod 220 to slide. And because the driven telescopic rod 220 is connected with the stirring rod 400 through the connecting rod 222, the sliding driven telescopic rod 220 drives the stirring rod 400 to do lifting motion. Meanwhile, the driving turntable 310 rotates with the driving drum 210, and the driven yaw sleeve 320 continuously performs reciprocating rotation under the driving of the driving turntable 310 due to the fact that the yaw thrust nail 321 on the driven yaw sleeve 320 is accommodated in the yaw driving groove 311, so as to drive the stirring rod 400 to perform reciprocating rotation. Further, the stirring rod 400 drives the pulse stirring paddle 500 to do lifting motion and reciprocating rotation motion together, and the lifting motion and the reciprocating rotation motion are alternately performed, so that slurry in the lower area of the filtered water pit 20 is pumped to the upper area, the purpose of re-stirring and suspending solid precipitates is achieved, and meanwhile, the reciprocating rotation motion of the pulse stirring paddle 500 has a certain horizontal stirring function;
to better explain the lifting and reciprocating rotation of the driving mechanism 40 and to explain the working principle of the pulse stirring paddle 500 in detail, it is specified that the driving drum 210 rotates one circle into one cycle, and the cycle is divided into four steps, namely a forward rotation step, an ascending step, a reverse rotation step and a descending step, and the numbers 1 to 4 respectively indicate the states of the reciprocating lifting assembly 200 at the four steps, and the numbers 5 to 8 respectively indicate the states of the reciprocating deflecting assembly 300 at the four steps. The following four steps are described in detail:
in the normal rotation step, as shown by reference numerals 1 in fig. 9 and 5 in fig. 10, the pressing drive column 221 is pressed against the lower groove portion 212 of the elevation drive groove 211, and the yawing thrust pin 321 is pressed against the intermediate portion 314 of the yawing drive groove 311. At this time, since the lower groove portion 212 of the lifting driving groove 211 is always at the same horizontal position, the pressing driving column 221 will not slide during the rotation of the driving drum 210, that is, the stirring mechanism 50 will not make a lifting motion, and the pulse stirring paddle 500 is located at the lower region of the filtered water pit 20. Meanwhile, since the middle portion 314 of the yaw driving groove 311 is a connection region between the large diameter portion 313 and the small diameter portion 312, and the distance from each position on the middle portion 314 to the rotation center of the driven yaw sleeve 320 is constantly changed, the driven yaw sleeve 320 performs a yaw motion at a proper time to adapt to the change of the distance, thereby driving the stirring rod 400 to rotate together. Further, the pulse paddle 500 rotates together with the paddle shaft 400. The rotation direction at this time is defined as a forward direction, and at this time, as shown in fig. 11, the opening/closing door 540 facing the water flow side is opened by the water flow, and the opening/closing door 540 facing away from the water flow is closed, that is, the opening/closing through hole 530 facing the water flow side is in an open state (the left opening/closing through hole 530 shown in fig. 11), and the opening/closing through hole 530 facing away from the water flow side is in a closed state. The partial sediment accumulated in the lower region of the filtered water sump 20 will be "scooped up" by the arc-shaped agitating surface 510 and enter the storage tank 520 through the opened and closed through-holes 530;
in the raising step, as shown by reference numerals 2 in fig. 9 and 6 in fig. 10, the pressing drive column 221 abuts against the transition portion 214 of the elevation drive groove 211, and the yawing thrust pin 321 abuts against the small diameter portion 312 of the yawing drive groove 311. Since the transition portion 214 connecting the lower trough portion 212 and the upper trough portion 213 is in a rising trend, the pressing driving rod 221 slides upwards along the transition portion 214 during the rotation of the driving drum 210, and further drives the stirring mechanism 50 to move upwards. At the same time, since the distance from the small diameter portion 312 of the yaw driving groove 311 to the rotation center of the driven yaw sleeve 320 is constant, the driven yaw sleeve 320 is kept at the conventional position, that is, the stirring mechanism 50 is not rotated without the yaw operation. At this time, the opening and closing doors 540 are all closed, that is, the opening and closing through holes 530 are also all in a closed state, and the sediment "scooped up" by the pulse stirring paddle 500 is still in the storage tank 520;
in the reverse rotation step, as shown by reference numerals 3 in fig. 9 and 7 in fig. 10, the pressing drive column 221 abuts against the upper groove portion 213 of the vertical movement drive groove 211, and the yawing thrust pin 321 abuts against the intermediate portion 314 of the yawing drive groove 311. At this time, since the upper groove 213 of the lifting driving groove 211 is located at the same horizontal position, the pressing driving column 221 will not slide, that is, the stirring mechanism 50 will not move up and down, and the pulse stirring paddle 500 is located at the upper region of the filtered water pit 20 during the rotation of the driving drum 210. Meanwhile, since the middle portion 314 of the yaw driving groove 311 connects the small diameter portion 312 and the large diameter portion 313, and the distance from each position on the middle portion 314 to the rotation center of the driven yaw sleeve 320 is constantly changed, the driven yaw sleeve 320 performs a yaw motion at a proper time to adapt to the change of the distance, thereby driving the stirring rod 400 to rotate together. Further, the pulse paddle 500 rotates together with the paddle shaft 400. At this time, the rotation direction is reversed, the opening/closing door 540 facing the water flow side is opened by the water flow, that is, the opening/closing through hole 530 facing the water flow side is in a smooth open state (as shown in fig. 12, the right opening/closing through hole 530 is located), and the opening/closing through hole 530 facing away from the water flow side is in a closed state. The cleaner slurry in the upper region of the filtered water sump 20 floods the storage tank 520 and "squeezes out" the sediment that was in the storage tank 520, thus pumping the sediment that was in the lower region of the filtered water sump 20 to the upper region;
in the lowering step, as shown by reference numerals 4 in fig. 9 and 8 in fig. 10, the pressing drive column 221 abuts against the transition portion 214 of the elevation drive groove 211, and the yawing thrust pin 321 abuts against the large diameter portion 313 of the yawing drive groove 311. Since the transition portion 214 connecting the upper groove portion 213 and the lower groove portion 212 is inclined downward, the pressing driving rod 221 slides downward along the transition portion 214 during the rotation of the driving drum 210, and drives the stirring mechanism 50 to move downward. At the same time, since the distance from each point on the large diameter portion 313 of the yaw driving groove 311 to the rotation center of the driven yaw sleeve 320 is constant, the stirring mechanism 50 does not rotate even if the driven yaw sleeve 320 is not moved to the existing position, that is, the yaw operation does not occur. At this time, the opening and closing doors 540 are closed, that is, the opening and closing through holes 530 are also closed, and the relatively clear slurry in the storage tank 520 is carried to the lower region of the filtered water sump 20 and mixed with the relatively turbid slurry.
It should be noted that, the four steps of one cycle have a sequential order, and under the driving of the driving mechanism 40, the stirring mechanism 50 makes four actions of forward rotation, upward rotation, reverse rotation, and downward rotation, and by using the characteristics of the pulse stirring paddle 500, in the rotation process of the pulse stirring paddle 500, the 'replacement' of the slurry inside the storage tank 520 and the slurry outside the storage tank 520 is realized. In the normal rotation, the turbid slurry rich in sediment in the lower region of the filtered water sump 20 is stored in the storage tank 520; while rising, the cloudy slurry is brought to the upper region of the filtered water pit 20; when the slurry is reversed, the clear slurry in the upper area is accommodated in the storage tank 520, and turbid slurry rich in precipitate is squeezed out; while descending, the clear slurry is brought to the lower region of the filtered water sump 20; again, in the forward rotation, the lower region of turbid slurry, which is rich in sediment, enters the storage tank 520 again and is squeezed out to give a clear slurry. The above steps are repeated, so that the solid sediment possibly generated in the slurry can be continuously stirred again and suspended, and the pulse stirring of the slurry is realized. Meanwhile, as shown in fig. 7, the arc-shaped stirring surface 510 is designed to make the reciprocating rotation motion of the pulse stirring paddle 500 have a certain horizontal stirring effect on the slurry.
It is emphasized that the opening and closing door 540 plays an important role in achieving "replacement" of the slurry inside the holding tank 520 with the slurry outside the holding tank 520. When the pulse stirring paddle 500 rotates forward, as shown in fig. 11, the opening/closing door 540 facing the water flow side is opened by the water flow (the opening/closing door 540 on the left side as shown in fig. 11), the opening/closing through hole 530 facing the water flow side is in an open state, and the opening/closing through hole 530 facing away from the water flow side (the right side as shown in fig. 11) is in a closed state, so that turbid slurry in the lower region is trapped in the storage tank 520 after flowing in; when the pulse stirring paddle 500 is rotated in reverse, as shown in fig. 12, the shutter 540 on the side facing the water flow will be opened by the water flow (the right shutter 540 as shown in fig. 12), the opening/closing through hole 530 on the side facing the water flow is in an open state, and the opening/closing through hole 530 on the side opposite to the water flow (the left side as shown in fig. 12) is in a closed state, so that the clear slurry in the upper region will be "trapped" in the reservoir 520 after flowing in. The opening and closing of the opening and closing door 540 are not controlled by an external driving source, but controlled by the water flow caused by the rotation of the pulse stirring paddle 500, so that the structure of the stirring mechanism 50 is simpler and the operation is reliable.
It can also be seen that the entire mixing device 10 suitable for semidry desulfurization has such a clear feature: the stirring mechanism 50 does not participate in the lifting movement during the rotation, specifically, the stirring mechanism 50 does not generate the lifting movement during the forward rotation, and the stirring mechanism 50 does not generate the descending movement during the reverse rotation. In this way, the stirring mechanism 50 is just positioned at the bottom of the tank during the positive rotation, and the sediment at the bottom of the tank can more fully enter the tank body because the stirring mechanism does not move upwards; similarly, the stirring mechanism 50 is just at the top of the tank when inverted, and since it does not undergo a descending motion, the sediment in the tank can be more sufficiently separated out, and thus the dispersion can be more sufficiently completed at the top of the tank. Therefore, the movement process not only can enable the sediment to enter the tank body more fully, but also can enable the sediment to be separated from the tank body at the top of the tank more fully so as to complete diffusion, and has a good effect.
In one embodiment, the end of the pressing driving rod 221 is provided with a universal ball (not shown), so that the friction coefficient between the pressing driving rod 221 and the lifting driving groove 211 can be reduced, and the friction force when the pressing driving rod 221 slides can be reduced.
In one embodiment, as shown in fig. 3, the number of the pulse stirring paddles 500 is two, and the two pulse stirring paddles 500 are arranged in a crossed manner, so that on one hand, the total capacity of the storage tank 520 can be made larger, thereby enhancing the effect of pulse stirring; on the other hand, the plurality of pulsed paddles 500 may also enhance the effect of the horizontal stirring action.
In conclusion, the stirring device 10 suitable for semidry desulfurization has the characteristics of simple and reliable structure, can replace the traditional pulse stirring system, and also achieves the purpose of re-stirring and suspending the solid sediment which is possibly generated.
The invention also provides a stirring process suitable for semi-dry desulphurization, which comprises the following steps:
firstly, injecting the slurry into a filtered water pit 20, and installing a fixed base 30 above the filtered water pit 20;
then, the driving mechanism 40 is installed on the fixed base 30, and the driving mechanism 40 is in driving connection with the stirring mechanism 50;
