Description

Technical Field

[0001] The present invention relates to the technical field of deep treatment devices for fly ash washing filtrate, and specifically to an intelligent dosing deep treatment device for fly ash washing filtrate. Background Art

[0002] The deep treatment device for fly ash filtrate is a treatment equipment for the filtrate generated during the fly ash washing process of waste incineration. This device is mainly used to remove harmful substances contained in the filtrate. The device adds specific chemicals to the filtrate to form granular flocs of pollutants, and then effectively separates them through sedimentation and filtration units.

[0003] However, during the long-term use of existing deep treatment devices, with the attachment of sediment, caking is likely to occur at the bottom, causing blockage of the sludge discharge pipe; and due to the unstable impurity content in the filtrate, the accumulation amount of sediment will change irregularly. Without effective detection means, the sediment may not be discharged in time, leading to blockage and even backflow; existing treatment devices not only lack effective means for dynamically detecting the sediment content, but also it is difficult to adjust the operation rate of the sludge removal device in real time according to the sediment content. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent dosing deep treatment device for fly ash washing filtrate to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An intelligent dosing deep treatment device for fly ash washing filtrate, including a base, on which a cylinder is installed. A driving motor is installed at the bottom end of the cylinder, and the output shaft of the driving motor penetrates the bottom end of the cylinder and is equipped with a sludge scraping and detecting component. A water inlet pipe is installed on the cylinder, a sludge discharge pipe is installed on the cylinder, and a central pipe is installed inside the cylinder through a connecting piece. The outlet of the water inlet pipe is located inside the central pipe, a reflecting plate is installed at the bottom end of the central pipe, and an anti-blocking component is installed inside the cylinder.

[0006] The treatment device is externally connected to a control system, which is used to control the entire treatment device. An intelligent dosing device is provided inside the cylinder, which is used to add a preset amount of chemicals into the cylinder. The sludge discharge pipe is externally connected to a sludge pumping device, which pumps the sediment inside the cylinder away through a sludge pumping pipe.

[0007] The fly ash washing filtrate is transported to the central pipe through the water inlet pipe. Then, the reflecting plate at the bottom of the central pipe makes the filtrate flow evenly to the surrounding of the cylinder and mix with the chemicals. Under the action of the chemicals, the harmful substances in the filtrate are neutralized, and the fine particles flocculate and precipitate to the bottom of the cylinder. The treated filtrate flows into the overflow end through the overflow plate and is discharged through the drain pipe, thus realizing the deep treatment of the fly ash washing filtrate.

[0008] Furthermore, an enlarged end is provided in the cylinder, an anti-blocking component is installed in the enlarged end, a mud discharge pipe is connected to the enlarged end, an overflow end is provided at the top of the cylinder, an overflow plate is installed on the overflow end, and a drain pipe is connected to the overflow end.

[0009] Furthermore, the anti-blocking component includes an anti-blocking device and a transmission member, the anti-blocking device is rotatably installed in the enlarged end, the transmission member is slidably installed in the enlarged end, the transmission member is movably connected to the anti-blocking device, and a reciprocating spring is installed between the transmission member and the enlarged end.

[0010] Furthermore, the anti-blocking device includes a rotating drum, which is provided with an inclined groove, and a plurality of anti-blocking blades are arranged in the rotating drum. The anti-blocking blades are provided with cutting angles, and the cutting angles are acute angles. The rotating drum is rotatably installed in the enlarged end, and the rotating drum is movably connected to the transmission member.

[0011] The tip of the cutting angle points to the entrance of the enlarged end, and the sediment enters the enlarged end from the entrance of the enlarged end. The sharp cutting angle on the anti-blocking blade breaks and guides the sediment, breaking the block sediment into small pieces to avoid sediment blockage.

[0012] The mud discharge device extracts the sediment through the mud discharge pipe, and the sediment enters the mud discharge pipe from the expanded end. The anti-blocking blade performs secondary crushing on the passing block sediment to prevent the block sediment from causing blockage. When the electromagnet in the energized state rotates with the mud removal scraper to the vicinity of the transmission ring, the transmission ring is attracted by the electromagnet and drives the entire transmission part to slide in the expanded end, the reciprocating spring is stretched, and the transmission column on the slide drives the rotating drum to rotate through the inclined groove, and the rotating drum drives the anti-blocking blade head to rotate. When the electromagnet rotates away, the transmission part is pulled back under the tension of the reciprocating spring, so that the anti-blocking blade head in the rotating drum rotates in the opposite direction, and so on and so forth, so that the anti-blocking blade head produces reciprocating rotation, and the reciprocating anti-blocking blade head stirs the flowing sediment to further prevent sediment blockage.

[0013] Furthermore, the transmission part includes a transmission ring, which is made of a magnetically adsorbable material and is slidably installed in the expanded end. A number of slides are installed on the transmission ring, and a transmission column is installed on the slide. The transmission column is slidably connected to the inclined groove, and the transmission ring is movably connected to the rotating drum. A reciprocating spring is installed between the transmission ring and the expanded end, and a number of limit plates are installed in the expanded end. The limit plates are located on both sides of the slide, and the slide is slidably connected to the limit plates.

[0014] Furthermore, the mud scraping detection assembly includes a driving shaft, which is connected to the output shaft of the driving motor, and the driving shaft is rotatably connected to the cylinder. A connecting head is installed on the driving shaft, and a plurality of detection scrapers are installed on the connecting head. The detection scrapers are connected to the cross bar. A transmission joint is provided at the bottom end of the cylinder, and a tooth groove is provided on the transmission joint. The transmission joint is meshed with the detection scraper through the tooth groove for transmission, and the connecting head is rotatably connected to the top of the transmission joint.

[0015] Both ends of the crushing plate are provided with crushing heads. When the crushing plate rotates, the crushing heads thereon can break up the lumpy sediment.

[0016] The control system activates the drive motor. The output shaft of the drive motor drives the drive shaft to rotate. The drive shaft drives the detection scraper to rotate around the drive shaft through the cross bar and the connector. The sludge removal scraper scrapes the sediment adhering to the bottom of the cylinder. When the detection scraper rotates, it drives the transmission gear on the transmission rod to rotate around the transmission joint. Under the action of the tooth groove, the transmission gear drives the transmission rod to rotate on its own axis. The transmission rod drives the crusher to rotate. The crushing plate breaks up the lumpy sediment scraped by the sludge removal scraper. Due to the inclined setting of the crushing plate, the rotation will increase the disturbance of the surrounding sediment, thereby driving the lumpy sediment to float, achieving the purpose of preventing the lumpy sediment from sinking to the bottom and avoiding secondary adhesion. At the same time, the floating sediment is more conducive to being broken by the crushing plate, increasing the crushing efficiency.

[0017] Further, the detection scraper includes a sludge removal scraper. The sludge removal scraper is installed on the connector. A transmission rod is rotatably installed on the sludge removal scraper. A transmission gear is installed on the transmission rod. The transmission gear is meshed and driven with the transmission joint through the tooth groove. A plurality of crushing plates are obliquely installed on the transmission rod. A plurality of flocculation detectors are installed on the sludge removal scraper. An electromagnet is provided inside the sludge removal scraper, and the position of the electromagnet corresponds to the position of the transmission ring.

[0018] The transmission rod obliquely passes through the crushing plate, and the crushing plate is inclined. The position of the electromagnet corresponds to the position of the transmission ring. When the energized electromagnet rotates with the sludge removal scraper to near the transmission ring, the electromagnet can attract the transmission ring to slide within the enlarged end.

[0019] Further, the flocculation detector includes a detection shell, a piezoelectric body, a backing plate and a detection rod. The detection shell is installed on the sludge removal scraper. An elastic membrane is installed on the detection rod. The elastic membrane is connected to the detection shell. A buoyancy head is installed at the top of the detection rod. The buoyancy head is made of a low-density material. A bottom plate is installed at the bottom of the detection rod. The bottom plate is slidably installed inside the detection shell. The backing plate is slidably installed inside the detection shell. The piezoelectric body is located between the backing plate and the elastic membrane. A force transmission spring is installed between the backing plate and the bottom plate.

[0020] The buoyancy head is affected by the buoyancy of the water body, floats upward and drives the bottom plate upward through the detection rod. The bottom plate squeezes the force - transmitting spring upward, and the force - transmitting spring transmits the pressure to the piezoelectric body through the backing plate. The piezoelectric body generates an electrical signal under the extrusion of the elastic membrane and the backing plate. When the water body is relatively clear, the intensity of the electrical signals received by the control system is relatively close. As the sediment sinks, when a large amount of sediment falls near the buoyancy head, it will change the buoyancy received by the buoyancy head, thus causing a difference in the electrical signals at this position. Since the sediment precipitates towards the bottom of the cylinder, the electrical signals of the flocculation detector at the bottom change first. Then, as the sediment increases, the electrical signals gradually show differences upwards. The control system judges the height of the sediment accumulation in real time according to the depth of the changing electrical signals. When there is too much sediment, the control system increases the output of the driving motor. The driving motor drives the sludge scraping and detecting assembly to run at an accelerated speed, and the sludge scraping and detecting assembly drives the anti - blocking assembly to accelerate synchronously. At the same time, the control system increases the output of the sludge pumping device, so that the sediment is pumped away more quickly, achieving the purpose of self - adapting adjustment of the running speeds of the sludge scraping and detecting assembly, the anti - blocking assembly and the sludge discharging speed according to the sediment accumulation amount.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The anti - blocking cutter head is used to crush the passing massive sediment a second time to prevent the massive sediment from causing blockage. The rotating electromagnet intermittently drives the transmission part to move, and cooperates with the reciprocating spring to make the transmission part do intermittent reciprocating motion, so that the anti - blocking cutter head rotates reciprocally. The reciprocally rotating anti - blocking cutter head stirs the passing sediment, further preventing the sediment from blocking.

[0022] 2. The driving motor is used to drive the sludge removal scraper to scrape the sediment attached to the bottom of the cylinder. Then, through the transmission joint, the transmission rod rotates self - rotatably to drive the crushing plate to rotate, and crush the massive sediment scraped by the sludge removal scraper. Due to the inclined setting of the crushing plate, the rotation will increase the disturbance of the surrounding sediment, and then drive the massive sediment to float, achieving the purpose of preventing the massive sediment from sinking to the bottom and avoiding secondary adhesion. At the same time, the floating sediment is more conducive to being crushed by the crushing plate, increasing the crushing efficiency.

[0023] 3. The influence of the sediment on the buoyancy of the buoyancy head is converted into detectable electrical signals by the flocculation detector. By using several groups of flocculation detectors in cooperation, the purpose of dynamically detecting the sediment accumulation height is achieved; when there is too much sediment, the control system increases the output of the driving motor. The driving motor drives the sludge scraping and detecting assembly to run at an accelerated speed, and the sludge scraping and detecting assembly drives the anti - blocking assembly to accelerate synchronously. At the same time, the control system increases the output of the sludge pumping device, so that the sediment is pumped away more quickly, achieving the purpose of self - adapting adjustment of the running speeds of the sludge scraping and detecting assembly, the anti - blocking assembly and the sludge discharging speed according to the sediment accumulation amount.

[0037] Working principle of the present invention: The fly ash washing filtrate is transported to the central pipe 6 through the water inlet pipe 3. Then, the reflecting plate 9 at the bottom of the central pipe 6 makes the filtrate flow evenly to the periphery of the cylinder body 2 and mix with the medicament. Under the action of the medicament, the harmful substances in the filtrate are neutralized, and the fine particles in it flocculate and precipitate to the bottom of the cylinder body 2. The treated filtrate flows into the overflow end 21 through the overflow plate 22 and is discharged through the drain pipe, thus realizing the deep treatment of the fly ash washing filtrate. The control system starts the driving motor 4, and the output shaft of the driving motor 4 drives the driving shaft 71 to rotate. The driving shaft 71 drives the detection scraper 73 to rotate around the driving shaft 71 through the cross bar 72 and the connector 74. The sludge removal scraper 731 scrapes the sediment attached to the bottom of the cylinder body 2. When the detection scraper 73 rotates, it drives the transmission gear 734 on the transmission rod 732 to rotate around the transmission joint 24. Under the action of the tooth groove, the transmission gear 734 drives the transmission rod 732 to rotate self - rotatably. The transmission rod 732 drives the crusher to rotate, and the crushing plate 735 crushes the massive sediment scraped by the sludge removal scraper 731. Due to the inclined setting of the crushing plate 735, the rotation will increase the disturbance of the surrounding sediment, thereby driving the massive sediment to float, achieving the purpose of preventing the massive sediment from sinking to the bottom and avoiding secondary adhesion. At the same time, the floating sediment is more conducive to being crushed by the crushing plate 735.

[0038] The sludge discharge device sucks out the sediment through the sludge discharge pipe 5. The sediment enters the sludge discharge pipe 5 from the enlarged end 23. The anti - clogging cutter head 812 performs secondary crushing on the passing massive sediment to prevent the massive sediment from causing blockage. When the energized electromagnet rotates to the vicinity of the transmission ring 831 following the sludge removal scraper 731, the transmission ring 831 is attracted by the electromagnet, thereby driving the entire transmission part 83 to slide within the enlarged end 23. The reciprocating spring 82 is stretched. The transmission column 833 on the slide plate 832 drives the rotating cylinder 811 to rotate through the inclined slot 813. The rotating cylinder 811 drives the anti - clogging cutter head 812 to rotate. When the electromagnet rotates away, under the pulling force of the reciprocating spring 82, the transmission part 83 is pulled back, so that the anti - clogging cutter head 812 in the rotating cylinder 811 rotates in the reverse direction. In this way, the anti - clogging cutter head 812 rotates reciprocally, and the reciprocally rotating anti - clogging cutter head 812 stirs the passing sediment to further prevent sediment blockage.

[0039] The buoyancy head 7331 is affected by the buoyancy of the water body, floats upward, and drives the bottom plate 7333 to move upward through the detection rod 7332. The bottom plate 7333 squeezes the force-transmitting spring 7334 upward, and the force-transmitting spring 7334 transmits the pressure to the piezoelectric body 7337 through the backing plate 7335. The piezoelectric body 7337 generates an electrical signal under the extrusion of the elastic membrane 7338 and the backing plate 7335. When the water body is relatively clear, the intensity of the electrical signal received by the control system is relatively close. As the sediment sinks, when a large amount of sediment falls near the buoyancy head 7331, it will change the buoyancy received by the buoyancy head 7331, thereby causing a difference in the electrical signal at this position. Since the sediment precipitates towards the bottom of the cylinder 2, the electrical signal of the flocculation detector 733 at the bottom changes first. Then, as the sediment increases, the electrical signals gradually differ from top to bottom. The control system judges the height of the sediment accumulation in real time according to the depth of the changing electrical signal. When there is too much sediment, the control system increases the output of the drive motor 4. The drive motor 4 drives the sludge scraping and detecting assembly 7 to run at an accelerated speed, and the sludge scraping and detecting assembly 7 drives the anti-blocking assembly 8 to accelerate synchronously. At the same time, the control system increases the output of the sludge pumping device, so that the sediment can be pumped out more quickly, achieving the purpose of self-adaptive adjustment of the running speeds of the sludge scraping and detecting assembly 7 and the anti-blocking assembly 8 and the sludge discharging speed according to the sediment accumulation amount.
