Description

Technical Field

[0001] The utility model relates to the technical field of wastewater cyclone feed box return slurry distribution device, in particular to a wastewater cyclone feed box return slurry distribution device with an anti-blocking function. Background Art

[0002] The dehydration of gypsum slurry produced in the limestone-gypsum wet flue gas desulfurization process is an important system in the flue gas desulfurization process. After the primary dehydration, the overflow liquid separated by the gypsum cyclone enters the wastewater cyclone feeding box, and its solid content is generally less than 10%. Part of the slurry in the wastewater cyclone feeding box is transported to the wastewater cyclone station through the wastewater cyclone feeding pump for further solid-liquid separation, and the other part enters the filtrate water tank through the overflow, and then is transported back to the absorption tower by the filtrate water pump for recycling.

[0003] During the actual design and operation process, it was found that the reuse process of first overflowing to the filtrate water tank and then using the filtrate water pump to return to the absorption tower will increase the selection of filtrate water tanks, filtrate water pumps and other ancillary equipment, directly leading to an increase in construction investment costs, and then increasing daily operation and maintenance costs. This is undoubtedly contrary to the current development direction of low-carbon environmental protection, energy conservation and emission reduction. Utility Model Content

[0004] The purpose of the utility model is to provide a wastewater cyclone feed box return slurry distribution device with an anti-blocking function to solve the problems raised in the above background technology.

[0005] In order to solve the above-mentioned technical problems, the utility model provides the following technical solutions: a wastewater cyclone feeding box return slurry distribution device with anti-blocking function includes a slurry diversion box, a movable partition is installed in the slurry diversion box, an anti-blocking flow-increasing pipe is installed at the bottom of the slurry diversion box, an adjustment module is installed at the top of the slurry diversion box, the slurry diversion box is installed on the wastewater cyclone feeding box, the slurry diversion box is used to store and divert overflow return slurry, the anti-blocking flow-increasing pipe is used to transmit the return slurry and increase the flow rate of the return slurry and prevent the pipeline interface from being blocked, the adjustment module is used to adjust the position of the movable partition, and the movable partition is used to partition the slurry diversion box into independent small box chambers.

[0006] The installation position of the slurry diversion box is lower than the overflow port of the wastewater cyclone feed box and higher than the absorption tower and the filtrate water tank, so that the overflowed reflux slurry can flow into the absorption tower and the filtrate water tank by its own gravity. The reflux slurry distribution device is externally connected to a control system, which controls the entire reflux slurry distribution device.

[0007] The slurry diversion box includes a bottom plate, on which an outer plate, a side plate and an overflow plate are installed, and a top plate is installed on the top of the side plate and the outer plate. The bottom plate, the side plate and the top plate are all connected to the wastewater cyclone feed box, and an arc groove is provided on the top plate, and a water outlet hole is provided on the bottom plate. When the return slurry in the wastewater cyclone feed box reaches the overflow water level, it will flow into the slurry diversion box through the overflow port, and the control system will start the motor at this time.

[0008] The anti-blocking flow-increasing pipe comprises a pipe body, which is mounted at the bottom end of the base plate, a flange is mounted at the bottom end of the pipe body, a driving ring is concentrically mounted on the pipe body, and an anti-blocking device is mounted in the pipe body. The flange is used to connect with the pipe.

[0009] The pipeline body comprises a pipeline shell, a flange is coaxially installed at the bottom end of the pipeline shell, a bottom support ring is installed in the pipeline shell, a gravity sensor is installed in the bottom support ring, a plurality of second thread strips are installed in the pipeline shell, and a driving ring is coaxially installed on the pipeline shell.

[0010] The anti-blocking device includes a first connecting rod and a bearing. The first connecting rod is installed in the pipeline shell. A spring telescopic rod is installed on the first connecting rod. A diverter cone is installed on the top of the spring telescopic rod. A fan wheel is concentrically installed on the bottom of the spring telescopic rod through a bearing. A plurality of permanent magnets are embedded in the side wall of the fan wheel. A plurality of first threaded strips are installed on the fan wheel. A drainage ring is installed on the fan wheel.

[0011] The drainage ring is used to fill the gap between the impeller and the pipe shell, and to guide the return slurry into the impeller through the inclined section at the top of the drainage ring. The diverter cone is used to reduce the resistance of the return slurry, and while guiding the return slurry into the impeller, reduce the loss of the impact force of the return slurry.

[0012] After the return slurry flows into the small box chamber separated by the movable partition, it flows out from the anti-blocking flow-increasing pipe. When the return slurry passes through the anti-blocking device, the return slurry impacts the fan wheel, driving the fan wheel to rotate. The rotation of the fan wheel stirs the return slurry evenly to prevent the impurities in the return slurry from accumulating at the outlet due to long-term operation, causing blockage;

[0013] The driving ring includes a driving housing, which is concentrically mounted on the pipe housing, an iron core is mounted inside the driving housing, and an enameled wire is mounted on the iron core. The enameled wire is connected to a control chip, which is connected to a power supply. The control chip is used to control the direction of the current. When the power supply is turned on, the control chip automatically controls the direction of the current flow, so that the enameled wire generates an electromagnetic field.

[0014] When the wastewater cyclone feed box has a large demand for drainage or the filtrate box and the absorption tower have a large demand for water, and the return slurry cannot meet the demand by its own weight, the control system turns on the power supply, and after the control chip in the drive ring is powered on, it automatically controls the current to flow into the enameled wire, and the electromagnetic field generated around the enameled wire drives the impeller with a permanent magnet embedded in it to accelerate the rotation. The high-speed rotation of the impeller drives the return slurry to quickly flow into the filtrate box or the absorption tower;

[0015] When the reflux slurry distribution device has been running for a long time or due to changes in the external temperature environment, resulting in an increase in impurities in the reflux slurry, causing the anti-blocking and flow-increasing pipe to be blocked and unable to drain, the water pressure in the slurry diversion box will increase due to the accumulation of reflux slurry. The fan wheel will drive the spring lifting and retracting rod to lengthen and fall due to the increase in water pressure, so that the first thread strip and the second thread strip are close to each other. When it falls to the bottom supporting ring in the pipe shell, the gravity sensor in the bottom supporting ring converts the changing gravity into an electrical signal and transmits it to the control system. After receiving the electrical signal, the control system turns on the power, and the drive ring generates an electromagnetic field to drive the fan wheel to rotate. When the wheel rotates, the first thread strip thereon drives the fan wheel upward along the trajectory of the second thread strip. Since the first thread strip and the second thread strip are disconnected and discontinuous, when the first thread strip rotates to the disconnection point, the fan wheel falls again due to loss of support. After falling, the fan wheel rotates and rises again, and this cycle is repeated. During the continuous falling process, vibrations are continuously generated, so that the blocked impurities are broken up and shaken off under the action of the vibration force and the fan wheel's own rotational force. When the blockage is cleared, as the water pressure decreases, the fan wheel rises and returns to its original position under the action of the spring telescopic rod, thereby achieving the purpose of clearing the blockage.

[0016] The adjustment module includes an adjustment shell, which is mounted on the top plate, an adjustment device is mounted inside the adjustment shell, and the adjustment device is slidably connected to the movable partition. An electric slide rail is embedded in the adjustment shell, and the electric slide rail is used to drive the sliding support to slide. An opening is provided at the top of the adjustment shell, and the motor output shaft passes through the opening and slides in the opening.

[0017] The electric slide rail drives the motor on the sliding support to slide, and the gear on the first motor output shaft follows the motor to move to the first rack. Then, the first rack is driven to slide on the slide groove base through the meshing transmission of the gear and the first rack. The first rack drives the partition panel to move through the slide groove block. Since the moving trajectory of the partition panel is arc-shaped, the first rack slides in the slide groove block when moving to prevent the partition panel from getting stuck. When the partition panel moves, the pulley on the plate body will roll along the outer plate and the overflow plate to reduce friction resistance; when the first rack drives the partition panel to move to the preset position, the electric slide rail controls the motor on the sliding support to slide toward the second rack, and then repeats the previous steps to make the second rack drive the partition panel to move to the preset position.

[0018] The adjusting device includes a sliding support and a slide groove base. The sliding support is installed on the top of the adjusting shell. A motor is installed on the sliding support. The motor output shaft passes through the adjusting shell and is installed with a gear. The slide groove base is installed on the top plate. A first rack and a second rack are slidably installed on the slide groove base. The first rack and the second rack are meshed with the gear for transmission. One side of the first rack and one side of the second rack are both slidably connected to the movable partition.

[0019] The movable partition includes a partition plate member, a water retaining strip is installed on the partition plate member, a second connecting rod is installed on the top of the partition plate member, a connecting plate is installed between the second connecting rods, the second connecting rod passes through the arc groove on the top plate, a slide block is installed on one side of the connecting plate, and the first rack and the second rack are respectively slidably installed on the slide block.

[0020] The partition plate comprises a plate body, a third connecting rod is installed on both sides of the plate body, a pulley is rotatably installed on the third connecting rod, a water retaining strip is installed on the plate body, and a second connecting rod is installed on the top of the plate body. The water retaining strip is installed at the pulley to prevent the backflow slurry from penetrating into the gap between the pulley and the plate body, and to prevent the backflow slurry from flowing into other small chambers from the gap between the pulley and the outer plate and the overflow plate.

[0021] Compared with the prior art, the utility model has the following beneficial effects: the utility model stores and diverts the reflux slurry overflowing from the wastewater cyclone feed box through the slurry diversion box, so that the reflux slurry flows into the filtrate box and the absorption tower by gravity, eliminating the step that the reflux slurry must pass through the filtrate box and then enter the absorption tower in the traditional process, so that the reflux slurry can directly flow into the absorption tower, greatly improving the working efficiency of the equipment, thereby reducing the volume of the filtrate box, using a smaller power filtrate water pump, and saving construction investment costs; through the movable partition and the adjustment module, the movable partition can be adjusted, so that the volume of the internal small box chamber of the slurry diversion box can be changed according to different needs; under normal conditions, the anti-blocking flow-increasing pipe is used to make the reflux slurry flow out evenly, and it is not easy to be blocked. At the same time, when the demand for reflux slurry is large, the flow rate of the reflux slurry can be increased by the driving ring to meet the demand. Finally, when the anti-blocking flow-increasing pipe is blocked due to long-term use or external environmental factors, it can be automatically cleared to ensure the normal operation of the slurry diversion box.

When the partition panel 45 moves, the pulley 452 on the plate body 451 will roll along the outer plate 13 and the overflow plate 12 to reduce friction resistance; when the first rack 313 drives the partition panel 45 to move to the preset position, the electric slide rail controls the motor 311 on the sliding support 312 to slide toward the second rack 316, and then repeats the previous steps to make the second rack 316 drive the partition panel 45 to move to the preset position.

[0046] The adjusting device 31 includes a sliding support 312 and a slide groove base 315. The sliding support 312 is installed on the top of the adjusting shell 32. A motor 311 is installed on the sliding support 312. The output shaft of the motor 311 passes through the adjusting shell 32 and is installed with a gear 314.

[0050] The pipeline body 23 includes a pipeline shell 231 , a flange 21 is coaxially mounted on the bottom end of the pipeline shell 231 , a bottom support ring 233 is mounted inside the pipeline shell 231 , a gravity sensor is mounted inside the bottom support ring 233 , a plurality of second thread strips 232 are mounted inside the pipeline shell 231 , and a drive ring 22 is coaxially mounted on the pipeline shell 231 .

[0051] The anti-blocking device 24 includes a first connecting rod 241 and a bearing 248. The first connecting rod 241 is installed in the pipe shell 231. A spring telescopic rod 243 is installed on the first connecting rod 241. A diverter cone 242 is installed on the top of the spring telescopic rod 243.

[0053] After the reflux slurry flows into the small box chamber separated by the movable partition 4, it flows out from the anti-blocking flow-increasing pipe 2. When the reflux slurry passes through the anti-blocking device 24, the reflux slurry impacts the impeller 244, driving the impeller 244 to rotate.

When the power supply is turned on, the control chip automatically controls the direction of the current so that the enameled wire 222 generates an electromagnetic field.

[0056] When the wastewater cyclone feed box has a large discharge volume demand or the filtrate box and the absorption tower have a large water volume demand, and the return slurry cannot meet the demand by its own weight flow, the control system turns on the power supply, and after the control chip in the drive ring 22 is powered on, the current is automatically controlled to flow into the enameled wire 222, and an electromagnetic field is generated around the enameled wire 222 to drive the impeller 244 with the permanent magnet 247 embedded therein to accelerate the rotation. The high-speed rotation of the impeller 244 drives the return slurry to quickly flow into the filtrate box or the absorption tower;

[0057] The working principle of the utility model is as follows: when the reflux slurry in the wastewater cyclone feed box reaches the overflow water level, it will flow into the slurry diversion box 1 through the overflow port, and the control system will start the motor 311 at this time. The electric slide rail drives the motor 311 on the sliding support 312 to slide, and the gear 314 on the output shaft of the first motor 311 moves with the motor 311 to the first rack 313, and then the first rack 313 is driven to slide on the chute base 315 through the meshing transmission of the gear 314 and the first rack 313, and the first rack 313 drives the partition plate 45 to move through the chute block 43. Since the moving trajectory of the partition plate 45 is an arc, the first rack 313 moves Slide in the slide block 43 to prevent the partition panel 45 from getting stuck. When the partition panel 45 moves, the pulley 452 on the plate body 451 will roll along the outer plate 13 and the overflow plate 12 to reduce friction resistance; when the first rack 313 drives the partition panel 45 to move to the preset position, the electric slide rail controls the motor 311 on the sliding support 312 to slide toward the second rack 316, and then repeats the previous steps to make the second rack 316 drive the partition panel 45 to move to the preset position.

[0058] After the reflux slurry flows into the small box chamber separated by the movable partition 4, it flows out from the anti-blocking flow-increasing pipe 2. When the reflux slurry passes through the anti-blocking device 24, the reflux slurry impacts the impeller 244, driving the impeller 244 to rotate. The rotation of the impeller 244 stirs the reflux slurry evenly to prevent impurities in the reflux slurry from accumulating at the water outlet due to long-term operation, causing blockage. When the wastewater cyclone feed box has a large discharge volume demand or the filtrate box and the absorption tower have a large water volume demand, and the reflux slurry's own weight flow alone cannot meet the demand, the control system turns on the power supply, and after the control chip in the drive ring 22 is powered on, the current is automatically controlled to flow into the enameled wire 222. An electromagnetic field is generated around the enameled wire 222 to drive the impeller 244 embedded with a permanent magnet 247 to accelerate the rotation. The high-speed rotation of the impeller 244 drives the reflux slurry to quickly flow into the filtrate box or the absorption tower.

[0059] When the reflux slurry distribution device runs for a long time or because of changes in the external temperature environment, resulting in an increase in impurities in the reflux slurry, causing the anti-blocking and flow-increasing pipe 2 to be blocked and unable to drain, the water pressure in the slurry diversion box 1 will increase due to the accumulation of the reflux slurry, and the fan wheel 244 will drive the spring lifting and retracting rod to lengthen and fall due to the increase in water pressure, so that the first thread strip 245 and the second thread strip 232 are close to each other, and when it falls to the bottom supporting ring 233 in the pipe shell 231, the gravity sensor in the bottom supporting ring 233 converts the changing gravity into an electrical signal and transmits it to the control system. After receiving the electrical signal, the control system turns on the power, and the drive ring 22 generates an electromagnetic field to drive the fan wheel 244 to rotate, and the fan wheel 244 rotates When the first thread strip 245 is rotated to the disconnection point, the fan wheel 244 falls again due to the loss of support. After falling, the fan wheel 244 rotates and rises again, and the cycle repeats. During the continuous falling process, vibration is continuously generated, so that the blocked impurities are broken up and shaken off by the vibration force and the rotational force of the fan wheel 244 itself. When the blockage is cleared, as the water pressure decreases, the fan wheel 244 rises and returns to its original position under the action of the spring telescopic rod 243, thereby achieving the purpose of clearing the blockage.
