Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to an electro-Fenton sewage treatment device. Background Art

[0002] Electro-Fenton wastewater treatment technology is an advanced oxidation process that combines electrochemistry and Fenton reaction. Its core principle is to generate hydrogen peroxide (H2O2) in situ through electrolysis. 2 O 2 ) and ferrous ions (Fe 2+ ), the two react to produce highly oxidizing hydroxyl radicals (·OH), thereby efficiently decomposing difficult-to-degrade organic matter. In the process of electro-Fenton sewage treatment, a sedimentation tank is needed to precipitate the iron sludge produced. The mud hopper under the sedimentation tank is a key component of the sludge treatment equipment. Through the cone or inverted pyramid structure design, gravity is used to make the iron sludge particles naturally settle and gather at the bottom of the mud hopper to achieve initial concentration, and then it is discharged through the mud discharge valve. Most of the sludge is iron sludge.

[0003] However, some iron sludge is easily adsorbed on the inner wall of the mud bucket, and the iron sludge is easy to adhere to the inner wall of the mud bucket to form hard scale, reducing the effective volume, and needs to be cleaned frequently. At present, there are some devices or equipment for cleaning the mud bucket, which generally adopts the method of scraping on the inner wall for cleaning. However, the setting of the scraper affects the shape of the inner wall of the mud bucket, resulting in protrusion from the inner wall, which not only affects the internal volume, but also affects the sliding path of iron sludge or other sludge. Part of the iron sludge is easily accumulated on the protruding part to form another group of hard scale. Summary of the invention

[0004] The object of the present invention is to provide an electro-Fenton sewage treatment device, which can externally adsorb and capture iron sludge on the inner wall of the mud hopper, and drive the iron sludge to move downward, preventing the iron sludge from being adsorbed on the inner wall for a long time to form hard scale, thereby implementing cleaning without affecting the internal shape and volume of the mud hopper.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electro-Fenton sewage treatment device, comprising a water collection tank, a regulating tank, an electrolytic cell and a neutralization tank, a sedimentation tank is arranged on one side of the neutralization tank, a mud bucket body is arranged at the bottom of the sedimentation tank, a plurality of box bodies are arranged on the periphery of the mud bucket body, the box bodies are arranged around the mud bucket body and are arranged in two rows up and down, telescopic rods are bolted on both sides of the box body, the side corners on the four sides of the mud bucket body are bolted with inclined rods, the surface of the inclined rod is slidably connected with a first sliding sleeve, a bracket is arranged below the mud bucket body, an electric hydraulic rod is bolted on the top of the bracket, the output shaft of the electric hydraulic rod is bolted with a connecting plate, a second sliding sleeve is bolted on one side of the connecting plate, the second sliding sleeve is slidably connected to the surface of the inclined rod, a window is provided on the surface of the box body close to the mud bucket body, and an electromagnet is also bolted inside the box body.

[0006] Preferably, it further includes a knocking component, which includes rollers, rubber rings and vertical plates. The number of the rollers is two groups. Vertical grooves are formed on both sides of the surface of the box body and located on both sides of the window. A transmission column is bolted to the inner wall of the roller. The number of the vertical plates is two groups and they are bolted to both sides inside the box body. The transmission column is rotatably connected to the surface of the vertical plate. A rubber ring with anti-slip ribs is arranged on the surface of the roller. A crank is rotatably connected between the two vertical plates on both sides. The crank is connected to the transmission column through a gear. A driving rod is rotatably connected to the surface of the crank. One end of the driving rod away from the crank is hinged with a movable column. The knocking component further includes sleeves penetrating through both sides of the surface of the box body. The inner wall of the sleeve is slidably connected with the movable column. One end of the driving rod is hinged with the movable column. An impact block is adhesively arranged at one end of the movable column away from the driving rod.

[0007] Preferably, the transmission column drives the crank to rotate in the way that a large gear drives a small gear.

[0008] Preferably, the impact block is made of rubber material.

[0009] Preferably, it further includes a shielding component, which includes a chute, a slider and a shielding plate. The chute is formed on the surface of the box body and above the window, and the number of the chutes is two groups. The slider is bolted to the shielding plate and slidably connected to the inner wall of the chute. The slider extends to the outside of the box body and contacts with the surface of the hopper body.

[0010] Preferably, the inclination angle of the inclined rod is the same as that of the four-side bend of the hopper body.

[0011] Preferably, an electric box is also bolted to the surface of the bracket. Ring bodies are bolted to both the upper and lower sides of the surface of the inclined rod. Touch sensors are fixed on the surface of the ring bodies.

[0012] Preferably, a bottom groove is formed at the bottom of the shielding plate.

[0013] Preferably, the hopper body is made of aluminum alloy material which is easy for magnetic field to pass through.

[0014] Preferably, the second sliding sleeve and the first sliding sleeve are fixed to each other through a connecting rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The present invention drives the first sliding sleeve, the second sliding sleeve, the telescopic rod and the box body to descend by opening the electro-hydraulic rod to contract its output shaft, and utilizes the action of the electromagnet to adsorb and capture the iron mud on the inner wall of the mud bucket, making the iron mud move downward. Through the two rows of designed electromagnets, the transfer is implemented, and finally the iron mud enters the lower part for discharge. Moreover, by using the action of the inclined rod, when the electromagnets are at a high position, they are scattered from each other to expand the magnetic field range and capture the iron mud in a larger range. When the electromagnets are at a low position, they are relatively concentrated to increase the effect of the magnetic field, so as to capture a relatively large amount of iron mud under the mud bucket body, thus adapting to the characteristic of the upper-wide and lower-narrow mud bucket, and implementing cleaning without affecting the internal shape and volume of the mud bucket, preventing the iron mud from being adsorbed for a long time to form hard scale.

[0017] 2. During the up-and-down movement of the box body in the present invention, the rollers and the rubber rings are driven to move along the surface of the mud bucket, and under the cooperation of the crank, the transmission column and the movable column, etc., the movable column and the impact block are driven to move repeatedly, so that the impact block strikes the surface of the mud bucket to generate vibration, which helps the iron mud or other sludge to break away from the inner wall of the mud bucket, making the iron mud more easily captured by the magnetic field.

[0018] 3. When the box body rises in the present invention, the shielding plate shields the window, forming a shielding space with the box body to weaken the magnetic field generated by the electromagnet and prevent a large amount of iron mud from rising together with the electromagnet. When the box body descends, the shielding plate can release the shielding of the window, allowing the magnetic field generated by the electromagnet to play a role again to drive the iron mud to descend, without frequently starting and stopping the electromagnet.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 - 13 , an electro-Fenton sewage treatment device, including a collecting pool 1, a regulating pool 2, an electrolytic cell 3 and a neutralization tank 4. A sedimentation tank 5 is arranged on one side of the neutralization tank 4, and a mud bucket body 6 is arranged at the bottom of the sedimentation tank 5. The wastewater passes through the collecting pool 1 → pre-distillation for specific pollutants → regulating pool 2 in sequence, equalizing the water quality and removing large particle impurities. The electrolytic cell 3 is the core device, with an iron anode and a cathode such as graphite or aluminum plate inside, and generates Fe 2+ and H 2 O 2, triggering the Fenton reaction to generate hydroxyl radicals ·OH to degrade organic matter. The wastewater enters the electrolytic cell 3 and electrolyzes to produce Fe under acidic conditions 2+ and H 2 O 2 . At the same time, the aeration system is used to stir and supply oxygen to complete the oxidation and degradation of organic matter. After the reaction, the wastewater enters the neutralization tank 4, and alkali is added to adjust the pH to neutral 7-9. Then, a flocculant is added to the flocculation tank to form flocs that are easy to settle. The wastewater flows into the sedimentation tank 5 for sedimentation separation. The supernatant enters the subsequent treatment unit, and the sludge is discharged into the mud bucket body 6 and finally enters the filter press through the sludge discharge valve for dehydration. The above is a simple description of the electro-Fenton sewage treatment technology, which is an existing mature technology, and other supporting facilities and equipment used therein will not be described in detail here.

[0035] The device further includes a knocking component 18, a shielding component 19, and several boxes 7 arranged around the mud bucket body 6. The boxes 7 are arranged around the mud bucket body 6 and are arranged in two rows up and down (only two rows are shown in the figure. In actual use, more rows of boxes 7 can be set according to the size of the mud bucket). Both sides of the box 7 are bolted with telescopic rods 8. The two ends of the telescopic rods 8 are respectively bolted to the boxes 7 on both sides. Diagonal rods 14 are bolted to the edges of the four sides of the mud bucket body 6. The inclination angle of the diagonal rods 14 is the same as the inclination angle of the four side edges of the mud bucket body 6. The four groups of diagonal rods 14 form a cone similar to the mud bucket body 6, and the cone angles are the same. A first sliding sleeve 9 is slidably connected to the surface of the diagonal rod 14. The number of the first sliding sleeves 9 corresponds to the number of rows of the boxes 7. The telescopic rods 8 located on both sides of the same row of corners are bolted to the first sliding sleeve 9. Thus, under the action of multiple telescopic rods 8, the boxes 7 in the same row are fixed to each other, and the boxes 7 and the first sliding sleeve 9 are fixed to each other. A bracket 10 is arranged below the mud bucket body 6. An electric hydraulic rod 12 is bolted to the top of the bracket 10. A connecting plate 21 is bolted to the output shaft of the electric hydraulic rod 12. A second sliding sleeve 13 is bolted to one side of the connecting plate 21. The second sliding sleeve 13 is slidably connected to the surface of the diagonal rod 14, and the second sliding sleeve 13 and the first sliding sleeve 9 are fixed to each other through a connecting rod, which makes the second sliding sleeve 13 and the first sliding sleeve 9 fixed to each other. During the movement of the second sliding sleeve 13, it can drive the first sliding sleeve 9 to move accordingly. A window 20 is opened on the surface of the box 7 close to the mud bucket body 6. An electromagnet 15 is also bolted inside the box 7. An electric box 11 is bolted to the surface of the bracket 10. A circuit for controlling the electric hydraulic rod 12 and the electromagnet 15 is arranged inside the electric box 11, such as electrical facilities such as relays, air switches, PLC controllers, and other intelligent control modules (these can be selected by those skilled in the art according to common sense), which are used to control the start and stop of the electrical components around the mud bucket. Rings 16 are bolted to the upper and lower sides of the surface of the diagonal rod 14. A touch sensor 17 is fixed on the surface of the ring 16. The touch sensor 17 is electrically connected to the control module inside the electric box 11.

[0036] When working, if it is necessary to clean the iron mud on the inner wall of the mud bucket, first turn on the electric hydraulic rod 12 to make its output shaft extend, so as to drive the second sliding sleeve 13, the first sliding sleeve 9, the telescopic rod 8 and the box body 7 to move obliquely upward along the direction of the inclined rod 14. After reaching the highest point, the upper first sliding sleeve 9 contacts the touch sensor 17. Then, the control circuit inside the electric box 11 controls the electric hydraulic rod 12 to turn on, and the output shaft of the electric hydraulic rod 12 stops extending. At the same time, the electromagnet 15 is turned on, and it generates magnetism. The material of the mud bucket body 6 is aluminum alloy, and the diamagnetism of aluminum alloy (μr≈1) allows the magnetic field to pass through almost unobstructed, permitting the magnetic field to penetrate. The external magnet can act on the internal iron mud. Then, the magnetic field generated by the electromagnet 15 acts on the iron mud on the inner wall of the mud bucket body 6 through the window 20 and the mud bucket body 6. Then, the output shaft of the electric hydraulic rod 12 is turned on again, and it drives the second sliding sleeve 13 and the first sliding sleeve 9 to descend through the connecting plate 21, and at the same time drives the upper and lower rows of box bodies 7 to descend. During the descent of the box body 7, the first sliding sleeves 9 on both sides are restricted by the direction of the inclined rod 14. During the downward movement, the telescopic rod 8 is gradually shortened. First, the telescopic rods 8 and the box bodies 7 on both sides converge towards the middle side. After the telescopic rods 8 on both sides contract to the limit, the telescopic rods 8 close to the middle side start to converge. The magnetic field generated by the electromagnet 15 moves downward and drives the internal iron mud to move downward. The upper row of electromagnets 15 adsorbs the iron mud on the upper half of the inner wall of the mud bucket and moves it to the inner wall on the middle side of the mud bucket body 6, while the lower row of electromagnets 15 adsorbs the iron mud on the lower half of the inner wall of the mud bucket and moves it to the bottom and discharges it through the drain valve at the bottom of the inner wall. The lower first sliding sleeve 9 contacts the touch sensor 17 located below. Then, the output shaft of the electric hydraulic rod 12 is temporarily shut down to stop the descent of the first sliding sleeve 9, the second sliding sleeve 13 and the box body 7. Then, the output shaft of the electric hydraulic rod 12 extends again, thereby driving the first sliding sleeve 9, the second sliding sleeve 13 and the box body 7 to rise. On the contrary, the first sliding sleeves 9 on both sides of the same row move relatively away from each other, and the nearest telescopic rod 8 is stretched. After reaching the limit, the telescopic rod 8 close to the middle side starts to be stretched until the upper first sliding sleeve 9 contacts the upper touch sensor 17, and the output shaft of the electric hydraulic rod 12 is closed again. At this time, the distance between the box bodies 7 expands again;In the above process, due to the action of the diagonal rod 14 and the first sliding sleeve 9, when the box body 7 and the telescopic rod 8 are at a high position, the telescopic rod 8 is in a stretched state, and the distance between the box bodies 7 is relatively large. The electromagnets 15 inside the box body 7 also move with the box body 7, changing the magnetic field distribution range. At a high position, the distance between the electromagnets 15 is relatively far apart. Under the action of gravity, the sludge particles settle towards the bottom of the sludge hopper body 6, and the accumulation amount in the deep bottom area is larger due to continuously receiving the iron sludge settling from the upper layer. Moreover, the sludge hopper body 6 is designed in an inverted cone shape, with a wider inner wall at the upper part and a narrower inner wall at the lower part. Therefore, at a high position of the sludge hopper body 6, the electromagnets 15 need to spread the distance between them to expand the magnetic field range and capture the iron sludge within a larger range. The iron sludge at the lower part is relatively concentrated. Therefore, as the first sliding sleeve 9, the second sliding sleeve 13, and the box body 7 descend, the distance between the box bodies 7 shortens, making the electromagnets 15 relatively concentrated. When the magnetic field directions of multiple electromagnets 15 are the same, the magnetic field intensity is approximately linearly superimposed, and the magnetic fields interact synergistically to capture a relatively large amount of iron sludge below the sludge hopper body 6.;

[0037] The knocking assembly 18 includes rollers 181, rubber rings 182, and vertical plates 183. The number of rollers 181 is two groups. Vertical grooves 1810 are opened on both sides of the surface of the box body 7 and located on both sides of the window 20 for the rollers 181 to pass through and contact the surface of the sludge hopper body 6. A transmission column 184 is bolted to the inner wall of the roller 181. The number of vertical plates 183 is two groups and they are bolted to both sides inside the box body 7. The transmission column 184 is rotatably connected to the surface of the vertical plate 183. A rubber ring 182 with anti-slip ribs is arranged on the surface of the roller 181. A crank 185 is rotatably connected between the two vertical plates 183 on both sides. The crank 185 is connected to the transmission column 184 through a gear. A driving rod 186 is rotatably connected to the surface of the crank 185. One end of the driving rod 186 away from the crank 185 is hinged with a movable column 189. The knocking assembly 18 further includes sleeves 187 penetrating through both sides of the surface of the box body 7. The inner wall of the sleeve 187 is slidably connected with the movable column 189. One end of the driving rod 186 is hinged with the movable column 189. A striking block 188 is adhesively arranged at the end of the movable column 189 away from the driving rod 186. The striking block 188 is made of rubber material.

[0038] During the up-and-down movement of the box body 7, it can drive the roller 181 and the rubber ring 182 to move along the surface of the mud bucket body 6. The roller 181 rotates to drive the transmission column 184 to rotate, and drives the crank 185 to rotate through a gear. The transmission column 184 drives the crank 185 to rotate in the way of a large gear driving a small gear. The crank 185 drives one end of the driving rod 186 to make a circular motion, and then the other end makes the movable column 189 slide repeatedly along the inner wall of the sleeve 187. This makes the impact block 188 at the other end of the movable column 189 frequently extend outside the sleeve 187 and contact the surface of the mud bucket body 6, generating vibration. Under the action of multiple knocking components 18, the inner wall of the mud bucket body 6 generates vibration, making it easier for the iron mud to break away from the adsorption with the inner wall of the mud bucket body 6 and making it easier for the iron mud to be captured by the magnetic field and move along.

[0039] Since the iron mud will move together with the up-and-down movement of the electromagnet 15, after the lower row of box bodies 7 are in the lowest position (while the upper row of box bodies 7 are in the position on the middle height side of the mud bucket), at this time, it is necessary to move the box body 7 upward. To prevent the continuous activation of the electromagnet 15 from driving the iron mud back to the upper part, the electromagnet 15 needs to be turned off during the upward movement of the box body 7. However, during the whole process, multiple up-and-down repeated movement operations are required, and the electromagnet 15 starts and stops frequently, which is easy to damage the electromagnet 15. Therefore, a shielding component 19 is provided. The shielding component 19 includes a chute 191, a slider 192 and a shielding plate 193. The chute 191 is opened on the surface of the box body 7 and above the window 20, and the number of the chutes 191 is two groups. The slider 192 is bolted to the shielding plate 193 and slidably connected to the inner wall of the chute 191, and the slider 192 extends outside the box body 7 and contacts the surface of the mud bucket body 6. A bottom groove 194 is opened at the bottom of the shielding plate 193 so as to fit with the top surface of the sleeve 187 during the closing process. During the upward movement of the box body 7, the friction between the slider 192 and the surface of the mud bucket body 6 makes the shielding plate 193 and the slider 192 not follow the box body 7 to rise temporarily. During the upward movement of the box body 7, the chute 191 is driven to rise until the bottom of the inner wall of the chute 191 contacts the slider 192, and then the shielding plate 193 will follow the box body 7 to rise, as Figure 9As shown, during the upward movement of the box body 7, the shielding plate 193 seals the window 20. Both the shielding plate 193 and the box body 7 are made of silicon steel, which can shield the magnetic field. In this way, during the upward movement, there is no need to turn off the electromagnet 15. The shielding formed by the closing of the shielding plate 193 and the inner wall of the box body 7 is used to greatly weaken the magnetic field (it should be noted that a small amount of magnetic induction lines will leak from the gap between the vertical groove 1810 and the roller 181 and the gap above the sliding groove 191, but the magnetic field becomes very weak and is greatly weakened. In actual use, the width of the vertical groove 1810 or the sliding groove 191 is designed to be narrow to prevent the leakage of magnetic field lines. Moreover, this part does not completely shield the magnetic field, but weakens the magnetic field so that a large amount of iron sludge is not driven to rise during the upward movement. Even if a small amount of iron sludge rises following the weakened magnetic field, it will fall again and precipitate after the device stops cleaning because it has detached from the adsorption on the inner wall of the sludge hopper, which can also prevent the iron sludge from continuously adhering to the inner wall of the hopper to a certain extent), so that during the upward movement of the box body 7 and the electromagnet 15, the iron sludge is not likely to rise synchronously with the box body 7 and the electromagnet 15 in a weak magnetic field environment. During the downward movement of the box body 7, the friction between the slider 192 and the sludge hopper body 6 causes the slider 192 and the shielding plate 193 not to follow the box body 7 downward temporarily until the slider 192 contacts the upper part of the inner wall of the sliding groove 191. At this time, the shielding plate 193 follows the box body 7 downward, but the shielding plate 193 no longer seals the window 20, allowing the magnetic field generated by the electromagnet 15 to act inside the sludge hopper body 6 to drive the iron sludge to fall. In this way, during the upward or downward movement, the electromagnet 15 remains continuously on, without the need for frequent start and stop; during the above process, as the box bodies 7 and the electromagnets 15 in the upper row move downward, the iron sludge above the sludge hopper is captured and moved to the height on the middle side of the sludge hopper, and the box bodies 7 and the electromagnets 15 in the lower row move downward, capturing the iron sludge at the middle side height of the sludge hopper and moving it downward, and then rising again, working multiple times. The electromagnets 15 in the upper and lower rows perform a hand-to-hand transfer-like action on the iron sludge, ultimately allowing the iron sludge on the inner wall of the sludge hopper to enter the lower sludge discharge valve to discharge the iron sludge.

[0040] It should be noted that those skilled in the art can adjust parameters and the number of devices based on common knowledge such as the number of electromagnets 15 and the power of the electromagnets 15 to meet the actual working conditions requirements, so as to prevent the magnetic field of the electromagnet 15 from being too strong and disturbing a large area of iron sludge that normally descends in the sewage. It only needs to adsorb and capture the iron sludge close to the inner wall of the sludge hopper. Moreover, during the movement of the iron sludge, it will also drive the surrounding other sludge mixed together to move, which can also avoid the long-term adsorption of sludge or iron sludge. This iron sludge cleaning function in the device can also be used when the device treats sewage.
