Description

Technical Field

[0001] This invention relates to the field of flue gas desulfurization technology, specifically to a slurry preparation device and method for producing desulfurizing agents with adjustable concentration. Background Technology

[0002] Desulfurizing agents are chemical substances that remove sulfur-containing substances from fuels such as coal and oil. Therefore, desulfurizing agents are widely used in industries such as power, metallurgy, chemical, and environmental protection to treat exhaust gases containing sulfur dioxide, enabling them to meet emission requirements.

[0003] When using desulfurizing agents, a slurry mixing tank is needed to prepare the desulfurizing agent powder into a slurry. However, the concentration of the slurry in the current slurry mixing tank cannot be controlled in real time during use. Furthermore, due to the limited stirring range of the stirring shaft during the preparation process, the desulfurizing agent cannot be evenly dispersed in the water, resulting in uneven concentration of the desulfurizing agent slurry and affecting the desulfurization effect.

[0004] Therefore, the present invention provides a slurry preparation device and method for producing desulfurizing agent with adjustable concentration. Summary of the Invention

[0005] To solve the above-mentioned technical problems, a slurry preparation device and method for producing desulfurizing agent with adjustable concentration are provided.

[0006] The technical solution of the present invention is as follows: The present invention provides a slurry preparation device for desulfurizing agent production with adjustable concentration, including a preparation tank and two stirring shafts vertically arranged inside the preparation tank;

[0007] The configuration tank is rotatably connected to a top cover, which has four mutually perpendicular and internally connected transverse sliding grooves. A slider is slidably installed in each of two adjacent transverse sliding grooves, and the upper ends of the two stirring shafts pass through the corresponding two sliders respectively.

[0008] The upper ends of the two stirring shafts are connected by a connecting rod, and the two ends of the connecting rod are respectively hinged to the two stirring shafts. A support plate is fixedly connected to the top of the cover by a connecting plate. A rotating shaft is vertically provided on the support plate. The lower end of the rotating shaft passes through the support plate and is fitted with a crank. A guide groove is provided on the crank. A locking pin is provided on the connecting rod for sliding connection with the guide groove. A driving device for driving the rotating shaft to rotate is provided on the support plate.

[0009] Each of the two stirring shafts is fitted with a gear, and a rack that meshes with the gear is provided on the lower end face of the upper cover located on the same side of the four transverse sliding grooves.

[0010] Each transverse chute has a first airbag at its outer end. The inner wall of the configuration tank has an inflation component that corresponds to each of the four first airbags. Each inflation component includes a fixing block fixed to the inner wall of the configuration tank. A stop block is located between two of the fixing blocks. Both of the stop blocks are fixedly connected to the lower end face of the upper cover. Each side wall of the fixing block corresponding to the stop block has an arc-shaped airbag.

[0011] The configuration tank is equipped with a pH sensor, and the upper end of the cover is provided with a water inlet pipe and a feed pipe. Both the water inlet pipe and the feed pipe are equipped with solenoid valves. The pH sensor and the solenoid valves are electrically connected through a relay. The bottom of the configuration tank is provided with a liquid outlet pipe.

[0012] Explanation: The above-mentioned slurry preparation device drives the crank to rotate via a drive mechanism. The crank then drives two sliders to slide back and forth in two transverse grooves via a connecting rod. Due to the meshing of the rack and gear, the stirring shaft rotates as it follows the sliders to agitate the slurry, expanding the stirring range of the stirring shaft and ensuring that the desulfurizer is evenly distributed in the slurry. When the slider slides to the sides of the corresponding transverse groove, it squeezes the first air bladder, allowing the two arc-shaped air bladders to alternately inflate and push the upper cover to rotate back and forth. The feeding pipe can add desulfurizer during the rotation of the upper cover, preventing all the desulfurizer from concentrating in one place and ensuring a more uniform distribution of the desulfurizer in the slurry. At the same time, the pH sensor can detect the pH value of the slurry in real time. The opening of the feeding pipe and water pipe is controlled by the pH value change of the slurry to control the slurry concentration in real time.

[0013] Furthermore, a bracket is fitted onto the configuration tank, and the bracket is provided with multiple legs. The bracket and the configuration tank are detachably connected by bolts, and the legs are inserted into slots provided on the lower end face of the bracket.

[0014] Note: The bracket can improve the stability of the container, and it has low manufacturing cost, good practicality, and the snap-fit ​​legs are easy to replace and maintain, making it convenient to use.

[0015] Furthermore, a rotating ring is fixedly connected to the lower end face of the upper cover, and multiple scrapers that contact the inner wall of the container are fixedly connected to the lower end face of the rotating ring.

[0016] Note: The reciprocating rotation of the top cover can drive the rotating ring to rotate, which in turn drives the scraper to clean the side wall of the mixing tank, preventing the desulfurizer from sticking to the side wall of the mixing tank.

[0017] Furthermore, the drive mechanism includes a first bevel gear sleeved on the upper end of the rotating shaft, and a motor mounted on the support plate;

[0018] A second bevel gear is fixedly sleeved on the output shaft of the motor for meshing with the first bevel gear to transmit power.

[0019] Note: The above-mentioned drive mechanism can drive the second bevel gear to rotate via a motor, and the second bevel gear will drive the shaft to rotate via the first bevel gear.

[0020] Furthermore, a transmission shaft is vertically provided on one side of the configuration tank. The lower end of the transmission shaft is provided with a cam that strikes the side wall of the configuration tank by rotation. The upper end of the transmission shaft passes through the upper cover and the support plate in sequence and is provided with a third bevel gear. The output shaft of the motor passes through the vertical plate provided on the support plate and is fixedly fitted with a fourth bevel gear for meshing with the third bevel gear to transmit power.

[0021] Explanation: The motor can drive the fourth bevel gear to rotate, which in turn drives the transmission shaft to rotate through the third bevel gear. This causes the transmission shaft to drive the cam to rotate, which then strikes the side wall of the mixing tank. The desulfurizing agent adhering to the mixing tank will fall off under the vibration generated by the strike.

[0022] Furthermore, the stirring shaft is composed of a hollow rod at the upper end and a sleeve at the lower end. The gear is fixedly sleeved on the hollow rod, and the stirring blade is fixedly sleeved on the sleeve. The hollow rod and the sleeve are connected by a spline and a spline groove for limiting sliding. The hollow rod is connected to the inner bottom surface of the sleeve by a spring. The inner bottom surface of the sleeve is provided with a piston rod that is slidably and sealingly connected to the hollow rod.

[0023] The slider has a cavity inside, and an air inlet is provided on the side wall of the hollow rod inside the cavity. A second airbag is provided at both ends of the slider, and the two second airbags are respectively connected to the cavity through corresponding gas channels provided inside the slider.

[0024] Explanation: When the slider drives the stirring shaft to slide to both sides of the transverse groove, the second air bladder will be compressed. The gas in the second air bladder will enter the hollow rod through the gas channel and inflation hole, causing the piston rod to drive the sleeve to descend under the action of air pressure. When the second air bladder is no longer compressed, the spring will drive the sleeve to return to its original position, so that the stirring shaft can move up and down during the stirring process, which increases the stirring range of the stirring shaft and further improves the stirring effect.

[0025] Furthermore, the two gas channels are staggered vertically, and a slip ring is fitted on the hollow rod, which slides up and down in the cavity to switch the connection between the inflation port and the corresponding gas channel. The slip ring, the cavity, and the hollow rod are all in sliding sealed connection.

[0026] Explanation: When a second airbag is compressed, the air pressure will first push the slip ring to slide, so that one gas channel is connected to the inflation port, ensuring that only one gas channel is connected to the inflation port when the hollow rod is inflated, thus preventing gas from entering the other second airbag.

[0027] Furthermore, both the upper and lower ends of the slip ring are provided with limiting rings to prevent the slip ring from contacting the cavity.

[0028] Note: The limiting ring prevents the slip ring from making complete contact with the top or bottom surface of the cavity, which would result in no gap between the slip ring and the cavity, preventing the slip ring from sliding up and down under air pressure.

[0029] On the other hand, the present invention provides a method of using the above-mentioned desulfurizing agent production slurry preparation device, comprising the following steps:

[0030] S1. Start the drive mechanism to make the drive mechanism drive the rotating shaft to rotate, the rotating shaft drives the crank to rotate, and the crank will drive the two sliders to slide sequentially in the two transverse sliding grooves through the connecting rod;

[0031] S2. When the two sliders slide, they will squeeze the first airbag in turn. After the first airbag is compressed, gas enters the corresponding arc-shaped airbag. The arc-shaped airbag inflates and elongates, and pushes the top cover to rotate through the stop. By alternately inflating the two arc-shaped airbags corresponding to each stop, the top cover can rotate back and forth.

[0032] S3. Add desulfurizing agent and water through the feeding pipe and water supply pipe. The feeding pipe adds desulfurizing agent into the preparation tank as it reciprocates with the upper cover. After the desulfurizing agent and water are added, slurry is obtained.

[0033] S4. When the slider slides in the transverse groove, it will drive the stirring shaft to slide together. Since the gear meshes with the corresponding rack, the stirring shaft will rotate to stir the slurry when it slides. During the stirring process, the pH sensor will detect the pH value of the slurry in real time, and control the opening of the feed pipe and water pipe through the real-time pH value to control the concentration of the slurry.

[0034] Explanation: The above method uses the top cover to drive the feeding pipe to rotate back and forth, which prevents all the desulfurizing agent from concentrating together. Two sliders drive the stirring shaft to slide back and forth in two transverse grooves, which expands the stirring range of the stirring shaft and allows the desulfurizing agent to be evenly distributed in the slurry. The concentration of the slurry is controlled in real time by a pH sensor and a solenoid valve.

[0035] The beneficial effects of this invention are:

[0036] (1) The device of the present invention drives the crank to rotate through the drive mechanism. The crank drives two sliders to slide back and forth in two transverse grooves through the connecting rod. The stirring shaft will rotate during the sliding process of following the slider to stir the slurry and expand the stirring range of the stirring shaft, so that the desulfurizing agent can be evenly distributed in the slurry. At the same time, the pH sensor can detect the pH value of the slurry in real time. The opening of the feeding pipe and the water supply pipe can be controlled by the change of the pH value of the slurry to control the slurry concentration in real time.

[0037] (2) When the slider of the device of the present invention slides to the two sides of the corresponding transverse groove, it will squeeze the first air bag, so that the two arc-shaped air bags can be alternately inflated to push the upper cover to rotate back and forth. The feeding pipe can add desulfurizing agent during the rotation of the upper cover, so as to avoid the desulfurizing agent from being concentrated together and make the distribution of desulfurizing agent in the slurry more uniform.

[0038] (3) When the slider of the device of the present invention slides to both sides of the transverse groove, the second air bag will be compressed. The gas in the second air bag will enter the hollow rod through the gas channel and the inflation hole, causing the piston rod to drive the sleeve to descend under the action of air pressure. When the second air bag is no longer compressed, the spring will drive the sleeve to return to its original position, so that the stirring shaft can move up and down during the stirring process, which improves the stirring range of the stirring shaft and further improves the stirring effect.

[0039] (4) The method of the present invention drives the feeding pipe to rotate back and forth through the top cover, so as to avoid the desulfurizing agent from being concentrated together. The stirring shaft is driven to slide back and forth in two transverse grooves through two sliders, which expands the stirring range of the stirring shaft, so that the desulfurizing agent can be evenly distributed in the slurry. The concentration of the slurry is controlled in real time through a pH sensor and a solenoid valve. Attached Figure Description

Detailed Implementation

[0051] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0052] Example 1

[0053] like Figure 1 , 2 As shown, a slurry preparation device for desulfurizing agent production with adjustable concentration includes a preparation tank 1 and two stirring shafts 11 vertically arranged inside the preparation tank 1.

[0054] like Figure 3 As shown, a top cover 2 is rotatably connected to the configuration tank 1. The top cover 2 is rotatably connected to the configuration tank 1 via an annular groove. The top cover 2 has four mutually perpendicular transverse sliding grooves connected at their inner ends, and a slider 21 slides in each adjacent transverse sliding groove. Figure 4 As shown, the upper ends of the two stirring shafts 11 respectively pass through the two corresponding sliders 21;

[0055] The upper ends of the two stirring shafts 11 are connected by a connecting rod 22, and the left and right ends of the connecting rod 22 are respectively hinged to the two stirring shafts 11. A support plate 23 is fixedly connected to the top of the cover 2 by a connecting plate. A rotating shaft 24 is vertically provided on the support plate 23. The lower end of the rotating shaft 24 passes through the support plate 23 and is fitted with a crank 241. A guide groove is provided on the crank 241. A locking post 221 for sliding connection with the guide groove is provided on the connecting rod 22. A drive device for driving the rotating shaft 24 to rotate is provided on the support plate 23. The drive device is a commercially available motor.

[0056] Each of the two stirring shafts 11 is fitted with a gear 111, and the lower end face of the upper cover 2 located on the same side of the four transverse sliding grooves is provided with a rack 25 that meshes with the gear 111.

[0057] Each transverse groove has a first airbag 26 at its outer end, such as Figure 6As shown, the inner wall of the configuration tank 1 is provided with an inflation component corresponding to the four first airbags 26 one by one, and each inflation component includes a fixing block 12 fixed on the inner wall of the configuration tank 1. A stop block 27 is provided at the middle position of two fixing blocks 12. Both stop blocks 27 are fixedly connected to the lower end face of the upper cover 2. Each fixing block 12 corresponding to the stop block 27 is provided with an arc-shaped airbag 13 on its side wall.

[0058] The configuration tank 1 is equipped with a pH sensor. The upper end face of the cover 2 is provided with a water inlet pipe 28 and a feed pipe 29. Both the water inlet pipe 28 and the feed pipe 29 are equipped with solenoid valves. The pH sensor and the solenoid valves are electrically connected through a relay. The pH sensor, relay and solenoid valve are all products of existing technology. The bottom surface of the configuration tank 1 is provided with a liquid outlet pipe 14.

[0059] A bracket 15 is fitted onto the configuration tank, and the bracket 15 has six legs. The bracket 15 is detachably connected to the configuration tank 1 by bolts, and the legs are inserted into slots on the lower end face of the bracket 15. Figure 5 As shown, a rotating ring 16 is fixedly connected to the lower end face of the upper cover 2, and six scrapers 161 that contact the inner wall of the configuration tank 1 are fixedly connected to the lower end face of the rotating ring 16.

[0060] The method for preparing desulfurizing agent slurry using the above-mentioned equipment includes the following steps:

[0061] S1. Start the drive mechanism to make the drive mechanism drive the rotating shaft 24 to rotate, the rotating shaft 24 drives the crank 241 to rotate, and the crank 241 will drive the two sliders 21 to slide back and forth in the two transverse sliding grooves through the connecting rod 22.

[0062] S2. When the two sliders 21 slide, they will squeeze the first airbag 26 in turn. After the first airbag 26 is compressed, the gas enters the corresponding arc-shaped airbag 13. The arc-shaped airbag 13 inflates and elongates, and pushes the upper cover 2 to rotate through the stop block 27. By alternately inflating the two arc-shaped airbags 13 corresponding to each stop block 27, the upper cover 2 can rotate back and forth.

[0063] S3. Add desulfurizing agent and water through feeding pipe 29 and water supply pipe 28. Feeding pipe 29 adds desulfurizing agent to preparation tank 1 as it reciprocates with the upper cover 2. After the desulfurizing agent and water are added, slurry is obtained.

[0064] S4. When the slider 21 slides in the transverse groove, it will drive the stirring shaft 11 to slide together. Since the gear 111 meshes with the corresponding rack 25, the stirring shaft 11 will rotate to stir the slurry when it slides. When the upper cover 2 rotates back and forth, it will drive the rotating ring 16 to rotate back and forth, so that the rotating ring 16 drives the scraper 161 to clean the preparation tank 1. During the stirring process, the pH sensor will detect the pH value of the slurry in real time, and control the opening of the solenoid valve in the feed pipe 29 and the water pipe 28 through the real-time pH value to control the concentration of the slurry.

[0065] Example 2

[0066] like Figure 7 As shown, this embodiment is basically the same as embodiment 1, except that the driving mechanism includes a first bevel gear 242 sleeved on the upper end of the rotating shaft 24, and a motor 3 set on the support plate 23. The motor 3 is a commercially available motor.

[0067] A second bevel gear 31 for meshing with the first bevel gear 242 to transmit power is fixedly sleeved on the output shaft of the motor 3;

[0068] The right side of the configuration tank 1 is provided with a vertical drive shaft 32. The lower end of the drive shaft 32 is provided with a cam 33 that strikes the side wall of the configuration tank 1 by rotating. The upper end of the drive shaft 32 passes through the upper cover 2 and the support plate 23 in sequence and is provided with a third bevel gear 34. The output shaft of the motor 3 passes through the vertical plate provided on the support plate 23 and is fixedly fitted with a fourth bevel gear 35 for meshing with the third bevel gear 34 for transmission.

[0069] The working principle of the above-mentioned drive mechanism is as follows: when the motor 3 rotates, it will drive the second bevel gear 31 and the fourth bevel gear 35 to rotate. The second bevel gear 31 will drive the rotating shaft 24 to rotate through the first bevel gear 242. At the same time, the fourth bevel gear 35 will drive the third bevel gear 34 to rotate. The third bevel gear 34 will drive the cam 33 to rotate through the transmission shaft 32, so that the cam 33 will strike the side wall of the configuration tank 1.

[0070] Example 3

[0071] like Figure 8 , 9 As shown, this embodiment is basically the same as embodiment 1, except that the stirring shaft 11 is composed of a hollow rod 112 at the upper end and a sleeve 113 at the lower end. The gear 111 is fixedly sleeved on the hollow rod 112, and the stirring blade is fixedly sleeved on the sleeve 113. The hollow rod 112 is connected to the spline on the sleeve 113 through a spline groove for limiting sliding. The hollow rod 112 is connected to the inner bottom surface of the sleeve 113 through a spring. The inner bottom surface of the sleeve 113 is provided with a piston rod 114 that is slidably and sealingly connected to the hollow rod 112.

[0072] like Figure 10 As shown, the slider 21 has a cavity inside, and the hollow rod 112 located inside the cavity has an inflation hole 116 communicating with the cavity on its side wall. The slider 21 has a second airbag 211 at both the left and right ends. The two second airbags 211 are respectively connected to the cavity through corresponding gas channels inside the slider 21.

[0073] The two gas channels are staggered vertically, and a slip ring 115 is fitted on the hollow rod 112. The slip ring 115 slides up and down in the cavity to switch the connection between the inflation port 116 and the corresponding gas channel. The slip ring 115 is slidably sealed to the cavity and the hollow rod 112. Both the upper and lower ends of the slip ring 115 are provided with limiting rings to prevent the slip ring 115 from contacting the cavity.

[0074] The working principle of the stirring shaft 11 is as follows: In the initial state, the air hole 116 is closed by the inner wall of the slip ring 115. When the slider 21 slides to the left side of the corresponding transverse slide groove, the second air bag 211 on the left side is compressed and the gas inside enters the cavity through the corresponding gas channel. The air pressure in the cavity increases and pushes the slip ring 115 to slide upward. At this time, the slip ring 115 no longer closes the air hole 116, and the second air bag 211 on the left side is connected to the hollow rod 112.

[0075] When the slider 21 slides to the right side of the corresponding transverse slide groove, the second airbag 211 on the right side is compressed, the air pressure in the cavity increases and pushes the slip ring 115 to slide downward, so that the second airbag 211 on the right side is connected to the hollow rod 112.

[0076] After the hollow rod 112 is inflated, the piston rod 114 pushes the sleeve 113 downward under the action of air pressure, causing the stirring shaft 11 to extend. When the second air bladder 211 is no longer compressed, the sleeve 113 gradually returns to its original position under the action of the spring, so that the length of the stirring shaft 11 also changes during the rotation, thereby expanding the stirring range of the stirring shaft 11.

8. The slurry preparation device for desulfurizing agent production with adjustable concentration according to claim 7, characterized in that, The slip ring (115) is provided with limiting rings at both the upper and lower ends to prevent the slip ring (115) from contacting the cavity.

9. The method of using the slurry preparation device for desulfurizing agent production according to any one of claims 1 to 8, characterized in that, Includes the following steps: S1. Start the drive mechanism to make the drive mechanism drive the rotating shaft (24) to rotate, the rotating shaft (24) drives the crank (241) to rotate, and the crank (241) will drive the two sliders (21) to slide back and forth in the two transverse sliding grooves through the connecting rod (22); S2. When the two sliders (21) slide, they will squeeze the first airbag (26) in turn. After the first airbag (26) is compressed, the gas enters the corresponding arc-shaped airbag (13). The arc-shaped airbag (13) inflates and elongates, and pushes the upper cover (2) to rotate through the stop (27). By alternately inflating the two arc-shaped airbags (13) corresponding to each stop (27), the upper cover (2) can rotate back and forth. S3. Add desulfurizing agent and water through the feeding pipe (29) and the water supply pipe (28). The feeding pipe (29) adds desulfurizing agent into the preparation tank (1) as it reciprocates with the upper cover (2). After the desulfurizing agent and water are added, slurry is obtained. S4. When the slider (21) slides in the transverse groove, it will drive the stirring shaft (11) to slide together. Since the gear (111) meshes with the corresponding rack (25), the stirring shaft (11) will rotate to stir the slurry when it slides. During the stirring process, the pH sensor will detect the pH value of the slurry in real time, and control the opening of the solenoid valve in the feed pipe (29) and water pipe (28) through the real-time pH value to control the concentration of the slurry.
