As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 and 2, the present invention discloses a stirring apparatus 10 suitable for semidry desulfurization, comprising: filtered water pit 20, fixed base 30, drive motor 40, drive mechanism 50 and stirring mechanism 60.

Wherein, the fixed base 30 is arranged above the filtered water pit 20, the driving mechanism 50 is arranged on the fixed base 30, the driving motor 40 provides power for the driving mechanism 50, and the driving mechanism 50 drives the stirring mechanism 60 to do reciprocating lifting motion and reciprocating rotation motion.

Specifically, as shown in fig. 3, the stirring mechanism 60 includes a stirring rod 100 and a stirring paddle 200, the stirring rod 100 is mounted on the fixed base 30, and the stirring paddle 200 is disposed on the stirring rod 100.

As shown in fig. 3, the driving mechanism 50 includes a lifting driving assembly 300 and a rotating driving assembly 400.

As shown in fig. 3, the lift drive assembly 300 includes a drive turret 310 and a stop collar 320. The driving turntable 310 is connected with the driving motor 40, the limit collar 320 is installed on the stirring rod 100, and the driving turntable 310 is in driving connection with the limit collar 320. The lifting driving assembly 300 drives the stirring paddle 200 to reciprocate through the stirring rod 100, so that the solid sediment possibly generated in the slurry is stirred and suspended by the lifting action.

In this embodiment, as shown in fig. 3, the driving turntable 310 is provided with a thrust column 311, and the limit collar 320 is sleeved on the thrust column 311. Preferably, the position limiting ring 320 is a semi-circular ring structure, and the center of the position limiting ring 320 coincides with the rotation center of the driving turntable 310. This may better cooperate with the rotational drive assembly 400 to drive the rotation of the agitator shaft 100, as will be described below.

In one embodiment, as shown in fig. 2 and 3, the position limiting collar 320 is connected to the stirring rod 100 through the bearing 110, so that when the stirring rod 100 rotates, the position limiting collar 320 does not rotate along with the stirring rod 100; when the stirring rod 100 goes up and down, the limiting sleeve ring 320 is driven to go up and down together, so that the limiting sleeve ring 320 can be always tightly matched with the driving turntable 310 while the rotating motion of the stirring rod 100 is not influenced.

As shown in fig. 3 and 4, the rotary driving assembly 400 includes a driven turntable 410 and a yaw sleeve 420. The driven turntable 410 is in driving connection with the driving turntable 310, the deflection sleeve 420 is sleeved on the stirring rod 100, the driven turntable 410 is provided with a sleeve poking rod 411 and a sleeve retaining rod 412, the sleeve retaining rod 412 is provided with an annular retaining piece 413, the deflection sleeve 420 is provided with a deflection poking groove 421 matched with the sleeve poking rod 411, the deflection poking groove 421 is of a cross spiral structure, and the deflection sleeve 420 is provided with a limiting avoiding groove 422 matched with the annular retaining piece 413. The rotation driving assembly 400 drives the stirring paddle 200 to rotate back and forth through the stirring rod 100, so that the slurry in the filtered water pit 20 is fully stirred.

In this embodiment, as shown in fig. 3, the driven turntable 410 is in belt-driven connection with the driving turntable 310. Preferably, the yaw sleeve 420 is shaft keyed to the agitator shaft 100.

The following explains the specific operation principle of the driving mechanism 50 with reference to the present embodiment:

as shown in fig. 2 and fig. 3, the driving motor 40 drives the driving turntable 310 to rotate, and since the limit collar 320 is sleeved on the thrust column 311 of the driving turntable 310, the driving turntable 310 drives the limit collar 320 to perform a lifting motion, and further drives the stirring mechanism 60 to perform an intermittent reciprocating lifting motion. Meanwhile, since the driven turntable 410 is drivingly connected with the driving turntable 310 through a belt, the driven turntable 410 rotates together with the driving turntable 310. During the rotation process, the sleeve poke rod 411 and the sleeve holding rod 412 on the driven turntable 410 are in contact with the deflection sleeve 420 in turn, so that the deflection sleeve 420 performs reciprocating deflection motion, and the stirring mechanism 60 is driven to perform intermittent reciprocating deflection motion;

to better explain the intermittent reciprocating up-and-down motion and the intermittent reciprocating yawing motion of the stirring mechanism 60, it is specified that the driving turntable 310 rotates one circle for one period, and the period is divided into two half periods according to whether the position change of the position-limiting lantern ring 320 occurs, namely an upper half period (as shown in fig. 5) and a lower half period (as shown in fig. 6), and the three states of the driving mechanism 50 and the stirring mechanism 60 in the upper half period are represented by numerals 1 to 3, and the three states of the driving mechanism 50 and the stirring mechanism 60 in the lower half period are represented by numerals 4 to 6;

in the first half cycle, as shown in fig. 5, the thrust column 311 on the driving turntable 310 rotates in the direction of the arrow, at this time, the rotation track of the thrust column 311 is inconsistent with the structure of the position-limiting collar 320, and the thrust column 311 presses and holds on the edge of the position-limiting collar 320. When the number mark 1 is changed to the number mark 2, the thrust column 311 pushes the limit lantern ring 320 to move upwards, and the stirring mechanism 60 also moves upwards along with the limit lantern ring; when the number is changed from 2 to 3, the pushing column 311 pushes the position-limiting collar 320 to move downward, and the stirring mechanism 60 also moves downward along with the downward movement. At the same time, during the rotation of the driving turntable 310, the driven turntable 410 also rotates in the direction of the arrow. It is noted that in the upper half cycle, in contact with the yaw sleeve 420 is the sleeve retaining rod 412 of the driven turntable 410. When in contact, the annular retaining piece 413 on the sleeve retaining rod 412 is located in the limiting and avoiding groove 422 of the deflection sleeve 420, that is, the annular retaining piece 413 is clamped in the limiting and avoiding groove 422, in this case, the driven turntable 410 does not drive the stirring mechanism 60 to rotate;

in the next half period, as shown in fig. 6, the pushing rod 311 on the driving turntable 310 rotates in the direction of the arrow, and at this time, the rotating track of the pushing rod 311 is identical to the structure of the position limiting collar 320, and the center of the position limiting collar 320 coincides with the rotating center of the driving turntable 310. Although the pushing rod 311 still presses on the edge of the position-limiting ring 320, the rotation of the pushing rod 311 does not drive the position-limiting ring 320 to move up and down, i.e. the stirring mechanism 60 does not move up and down. At the same time, during the rotation of the driving turntable 310, the driven turntable 410 also rotates in the direction of the arrow. In the next half cycle, in contact with the yaw sleeve 420 is the sleeve tap lever 411 of the slave dial 410. As shown, when the number mark 4 changes to the number mark 5, the end of the sleeve tap lever 411 will be inserted into the deflecting tap groove 421 and pressed against the groove wall of the deflecting tap groove 421 as the driven turntable 410 rotates. Since the wobble groove 421 is a spiral structure, the rotation of the sleeve lever 411 will push the wobble sleeve 420 to rotate, as shown in the figure, from numeral 4 to numeral 6. In the next half period, the sleeve tap lever 411 will be inserted into the deflection tap slot 421 on the other side, and the sleeve tap lever 411 will drive the deflection sleeve 420 to rotate in the opposite direction. Since the offset sleeve 420 is connected to the stirring rod 100 by the shaft key, the stirring mechanism 60 rotates along with the rotation of the offset sleeve 420, i.e., performs a stirring operation.

It should be noted that, in the same period, the stirring mechanism 60 performs the lifting motion in the first half period and performs the rotating motion in the second half period, and the lifting motion and the rotating motion of the stirring mechanism 60 are performed alternately. Moreover, in two adjacent periods, since the deflecting toggle slots 421 have a cross-helical structure, the rotation directions of the stirring mechanism 60 in the two next half periods are opposite. Thus, in the stirring process of the slurry, both horizontal stirring and vertical stirring exist, and the action directions of the horizontal stirring and the vertical stirring are changed, so that the influence of gravity on the precipitation in the slurry can be reduced, and the slurry in the filtered water pit 20 can be stirred more fully and thoroughly.

It is emphasized that during the upper half cycle, as shown in fig. 5, the sleeve retaining rod 412 of the driven turntable 410 contacts the deflection sleeve 420, and the annular retaining piece 413 on the sleeve retaining rod 412 is located in the limit avoiding groove 422, so that the deflection sleeve 420 is prevented from being interfered and deflected during the process of lifting the stirring mechanism 60. Only when the deflection sleeve 420 is kept not to deflect and enters the next half period, the sleeve poke rod 411 can accurately pass through the limiting avoiding groove 422 and be embedded into the spiral deflection poke groove 421, and smooth transition between the first half period and the next half period is completed. Similarly, in order to make the transition between the upper half cycle and the lower half cycle smoother, it is necessary to ensure that the sleeve tap lever 411 can be accurately inserted into the helical deflecting tap groove 421 during the transition of the half cycle. To this end, in the present embodiment, whenever the annular retaining piece 413 is about to disengage from the yaw sleeve 420 during a transition of a half cycle, as indicated by numeral 4 in fig. 6, the sleeve tap lever 411 is already in contact with the yaw sleeve 420; as shown in FIG. 6 at numeral 6, the sleeve tap 411 has not yet fully disengaged from the yaw sleeve 420 and the annular retainer 413 has come into contact with the yaw sleeve 420. Thus, smooth transition between the upper half cycle and the lower half cycle can be ensured.

In one embodiment, a universal ball (not shown) is disposed at the end of the sleeve tap lever 411, so that the friction coefficient between the sleeve tap lever 411 and the deflection tap groove 421 can be reduced, and the friction force is reduced, so that the sleeve tap lever 411 can rotate more smoothly.

In one embodiment, as shown in fig. 3, the paddle 200 includes a large paddle 210 and a small paddle 220, so that the stirring effect of the stirring mechanism 60 can be enhanced and the slurry can be better mixed.

It is specifically noted that in order to better suspend the solids that may be present in the slurry by agitation with the lifting action, i.e., to enhance the effectiveness of the pulsed agitation, the present invention, in one embodiment, is specifically modified to include an agitation mechanism 60:

specifically, as shown in fig. 3, 7 and 8, the stirring mechanism 60 of the present invention further includes a pulse assist paddle 300. The pulse auxiliary paddle 300 is installed on the stirring rod 100, the pulse auxiliary paddle 300 has an arc-shaped stirring surface 310, the pulse auxiliary paddle 300 is provided with a storage tank 320 and a plurality of auxiliary through holes 330, the plurality of auxiliary through holes 330 are arranged on the arc-shaped stirring surface 310 at intervals, each auxiliary through hole 330 is communicated with the storage tank 320, and the storage tank 320 is provided with an upper through hole 321 and a side through hole 322.

In the next half cycle, the stirring mechanism 60 makes a rotational movement, and the pulse assist paddle 300 also rotates together. Since the sediment in the slurry will accumulate at the bottom under the action of gravity, and the rotation of the pulse auxiliary paddle 300 will also be at the bottom of the filtered water sump 20, during the rotation of the pulse auxiliary paddle 300, the part of the sediment accumulated at the bottom will be "scooped up" by the arc-shaped stirring surface 310 and enter the storage tank 320 through the auxiliary through holes 330. Then in the last half cycle, as the stirring mechanism 60 makes an ascending movement, the pulse assist paddle 300 ascends together and no longer rotates. As shown in fig. 7, during the ascending process, the water flow generated by the ascending of the pulse auxiliary paddle 300 flows into the storage tank 320 through the upper through hole 321, and flows out of the storage tank 320 through the side through hole 322 and the auxiliary through hole 330, and the sediment originally in the storage tank 320 is carried out of the storage tank 320 by the water flow. In this way, the sediment accumulated in the lower area of the slurry is brought to the upper area of the slurry, and the effect of the pulse stirring is enhanced. Therefore, the pulse auxiliary paddle 300 can stably scoop up and contain the sediment at the bottom of the tank in the storage tank 320 in terms of the feeding of the sediment, most of the sediment can be smoothly separated from the storage tank 320 and reach the upper area of the slurry in the process of rising, and a small part of the sediment can be separated from the storage tank 320 in the process of rapidly falling, so that the sediment can be more fully separated from the storage tank 320 through rising and falling motions, and a good effect is achieved. It will be appreciated that due to the structural design of the storage tank 320, a large portion of the sediment may be released from the storage tank 320 and reach the upper region of the slurry during the ascending process, which further facilitates the spreading of the sediment within the tank.

It should be particularly noted that, in the present invention, the driving mechanism 50 includes the lifting driving assembly 300 and the rotating driving assembly 400, and the lifting driving assembly 300 and the rotating driving assembly 400 cooperate with each other to finally realize the alternate lifting movement and rotating movement of the stirring mechanism 60, during the stirring process of the slurry, there is horizontal stirring and vertical stirring, and the action directions of the horizontal stirring and the vertical stirring are also changed, so that the influence of gravity on the precipitation in the slurry can be reduced, and the slurry in the filtered water pit 20 can be stirred more fully and completely. More importantly, the lifting driving assembly 300 and the rotating driving assembly 400 which are matched with each other are arranged, the pulse auxiliary paddle 300 is driven to lift and rotate, the pulse auxiliary paddle 300 can scoop up the sediment and enter the storage tank 320 in the rotating process, and most of the sediment can smoothly separate from the storage tank 320 and reach the upper area of the slurry in the lifting process (particularly the lifting process), so that the sediment can be more favorably dispersed in the tank and cannot return to the bottom of the tank in the rapid descending process.

In summary, the stirring device 10 for semidry desulfurization according to the present invention has both horizontal stirring and pulse stirring, and has a simple structure, and can achieve the purpose of fully stirring the slurry and preventing the slurry from settling.

The invention also provides a stirring process suitable for semi-dry desulphurization, which comprises the following specific steps of:

first, the slurry is poured into the filtered water pit 20, and the fixed base 30, the driving mechanism 50 and the stirring mechanism 60 are mounted above the filtered water pit 20;

then, the driving motor 40 is in driving connection with the driving mechanism 50;

after the driving motor 40 is started, the driving mechanism 50 drives the stirring mechanism 60 to perform horizontal rotation and vertical lifting movement. Specifically, the driving mechanism 50 is divided into a lifting driving assembly 300 and a rotating driving assembly 400. The lifting driving assembly 300 drives the stirring mechanism 60 to perform intermittent reciprocating vertical lifting motion, and the rotating driving assembly 400 drives the stirring mechanism 60 to perform intermittent reciprocating horizontal rotating motion.

Also, the horizontal rotation motion and the vertical lifting motion are alternately performed. In one cycle, the first half cycle, the stirring mechanism 60 completes one ascending and descending motion; in the next half cycle, the stirring mechanism 60 completes a single-directional horizontal rotation. In the next cycle, the first cycle, the stirring mechanism 60 still completes one ascending and descending action; in the next half cycle, the stirring mechanism 60 completes a horizontal rotation in the opposite direction.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
