Description

Technical Field

[0001] This utility model relates to the technical field of electrocoagulation flotation equipment, specifically to an electrocoagulation flotation device. Background Technology

[0002] Electrocoagulation and flotation equipment is a type of water treatment equipment that combines two technologies: electrocoagulation and flotation. The electrocoagulation process uses direct current to cause soluble metal anodes (such as aluminum and iron) to lose electrons and generate metal cations. These cations undergo hydrolysis, polymerization, and other reactions to form various hydroxyl complexes, polynuclear hydroxyl complexes, and hydroxides, thereby coagulating pollutants in the water and causing them to precipitate or form easily separable flocs. Flotation involves introducing tiny air bubbles into the water, causing suspended solids or hydrophobic substances in the water to adhere to the surface of the bubbles and float to the surface with them, thus achieving solid-liquid separation.

[0003] Existing electrocoagulation flotation equipment requires frequent wastewater treatment, resulting in a large amount of waste residue adhering to the inner wall of the flotation tank. In order not to affect the subsequent wastewater treatment effect, it is necessary to clean the waste residue on the inner wall of the flotation tank. However, the internal space of the flotation tank is very small, and there are also dissolved air tanks and other mechanisms installed inside, making it very inconvenient to clean the inner wall of the flotation tank. Utility Model Content

[0004] The purpose of this invention is to provide an electrocoagulation flotation device to solve the problem mentioned in the background art that the currently used electrocoagulation flotation devices are inconvenient to clean the inner wall of the flotation tank quickly.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electrocoagulation flotation device, comprising: a base and a dissolved air tank, wherein an electrocoagulant is installed on the top of the base, a pipe is connected to one side of the electrocoagulant, and a flotation tank is connected to the side of the pipe away from the electrocoagulant, and the dissolved air tank is installed inside the flotation tank;

[0006] A drive motor is installed at the bottom of the air flotation tank. An output shaft is connected to the top of the drive motor via a coupling. Both sides of the output shaft are connected to drive belts via pulleys. A rotating shaft is connected to the side of the drive belt away from the output shaft.

[0007] Preferably, a gear is connected to the outer side of the rotating shaft, and an internal gear ring is meshed with the outer side of the gear.

[0008] Preferably, a scraper is installed on the top of the internal gear ring, and a slider is connected between the bottom of the internal gear ring and the circular groove of the flotation tank.

[0009] Preferably, the inside of the flotation tank is equipped with a collection tray, a slag discharge tray is installed in the middle of the collection tray through a groove, and a connecting rod is installed on the top of the slag discharge tray.

[0010] Preferably, a connecting ring is installed at the top of the connecting rod, and a telescopic block is provided on the outer side of the connecting ring.

[0011] Preferably, a movable spring is connected between the telescopic block and the groove of the flotation tank, and a locking rod is connected through the middle of the telescopic block.

[0012] Preferably, a protrusion is installed on one side of the lever.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this electrocoagulation flotation equipment, the drive motor can be started according to the usage requirements. The drive motor will drive the output shaft to rotate through the coupling. The rotation of the output shaft will drive the rotating shaft and gear to rotate under the cooperation of the pulley and the drive belt. The gear is meshed with the inner wall of the inner gear ring, so the inner gear ring will rotate through the gear. A scraper is installed on the top of the inner gear ring. When the inner gear ring rotates, it will drive the scraper on the top to rotate along the inner wall of the flotation tank. The scraper can scrape and clean the waste residue inside the flotation tank, so as not to affect the subsequent wastewater treatment effect. This is the usage feature of this electrocoagulation flotation equipment.

[0014] 1. When the inner wall of the flotation tank needs to be cleaned, this electrocoagulation flotation equipment only requires starting the drive motor. With the cooperation of the output shaft and the drive belt, the rotating shaft drives the gear to rotate. The rotation of the gear drives the internal gear ring to rotate, which in turn drives the scraper at the top to rotate along the inner wall of the flotation tank. The scraper can clean the inner wall of the flotation tank, thus facilitating and quickly cleaning the waste residue remaining on the inner wall of the flotation tank.

[0015] 2. When it is necessary to collect the waste residue inside the flotation tank, the telescopic block of this electrocoagulation flotation equipment only needs to be pulled to one side, so that the telescopic block drives the locking rod and the protrusion to move. When the protrusion does not limit the connecting ring, the slag discharge plate can be pulled to the top of the collection plate through the connecting ring and the connecting rod, so that the slag discharge plate can be pulled out from the inside of the flotation tank. At this time, the waste residue inside the flotation tank can be collected and processed conveniently and quickly. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 This utility model provides a technical solution: an electrocoagulation flotation device, comprising: a base 1 and a dissolved air tank 5, an electrocoagulator 2 is installed on the top of the base 1, a pipe 3 is connected to one side of the electrocoagulator 2, and a flotation tank 4 is connected to the side of the pipe 3 away from the electrocoagulator 2, and the dissolved air tank 5 is installed inside the flotation tank 4.

[0025] A drive motor 6 is installed at the bottom of the flotation tank 4. The top of the drive motor 6 is connected to an output shaft 7 via a coupling. Both sides of the output shaft 7 are connected to drive belts 8 via pulleys. A rotating shaft 9 is connected to the side of the drive belt 8 away from the output shaft 7. A gear 10 is connected to the outside of the rotating shaft 9. An internal gear ring 11 is meshed with the outside of the gear 10. A scraper 12 is installed on the top of the internal gear ring 11. A slider 13 is connected between the bottom of the internal gear ring 11 and the circular groove of the flotation tank 4. Two sets of scrapers 12 are symmetrically installed about the center line of the internal gear ring 11.

[0026] In practical implementation, when it is necessary to clean the waste residue on the inner wall of the flotation tank 4, the drive motor 6 at the bottom of the flotation tank 4 can be started. The drive motor 6 will drive the output shaft 7 to rotate through the coupling. Both sides of the output shaft 7 are connected to the drive belt 8 through pulleys, and the other end of the drive belt 8 is connected to the rotating shaft 9 through the pulley. Therefore, with the cooperation of the drive belt 8 and the pulley, the rotating shaft 9 can drive the gear 10 on the outer side to rotate. The outer side of the gear 10 is engaged with the gear. There is an internal gear ring 11, and the bottom of the internal gear ring 11 slides in the circular groove at the bottom of the flotation tank 4 via the slider 13. Therefore, when the gear 10 rotates, it will drive the internal gear ring 11 to rotate. A scraper 12 is also installed on the top of the internal gear ring 11. When the internal gear ring 11 rotates, it will drive the scraper 12 on the top to rotate along the inner wall of the flotation tank 4. At this time, the scraper 12 can clean the inner wall of the flotation tank 4, thereby preventing a large amount of waste residue from adhering to the inner wall of the flotation tank 4 and affecting the subsequent sewage treatment effect.

[0027] See Figure 1 , Figure 3 and Figure 5 It can be seen that when it is necessary to clean the inner wall of the flotation tank 4, the transmission motor 6 and the output shaft 7 can drive the transmission belt 8 to rotate. The rotation of the transmission belt 8 will drive the rotating shaft 9 and the gear 10 to rotate through the pulley. Since the gear 10 and the internal gear ring 11 mesh with each other, the internal gear ring 11 will rotate and drive the scraper 12 at the top to move along the inner wall of the flotation tank 4, thereby cleaning the inner wall of the flotation tank 4.

[0028] The flotation tank 4 is equipped with a collection tray 14. A slag discharge tray 15 is installed in the middle of the collection tray 14 through a groove. A connecting rod 16 is installed on the top of the slag discharge tray 15. A connecting ring 17 is installed on the top of the connecting rod 16. A telescopic block 18 is provided on the outside of the connecting ring 17. A movable spring 19 is connected between the telescopic block 18 and the groove of the flotation tank 4. A locking rod 20 is connected through the middle of the telescopic block 18. A protrusion 21 is installed on one side of the locking rod 20. The protrusion 21 is inserted into one side of the connecting ring 17 through a groove.

[0029] In practical implementation, when the waste residue inside the flotation tank 4 needs to be collected, due to the inclined structure of the top of the collection plate 14, the waste residue inside the flotation tank 4 will slide from the collection plate 14 into the discharge plate 15 under the influence of gravity. Then, the telescopic block 18 can be pulled to one side, so that the telescopic block 18 drives the protrusion 21 to move out of the groove of the connecting ring 17 through the locking rod 20. At the same time, the movable spring 19 will be in a stretched state. Without the protrusion 21 inserted into the connecting ring 17, the connecting ring 17 can be closed. 7. Pull upwards. The bottom of the connecting ring 17 is connected to the slag discharge plate 15 through the connecting rod 16. Therefore, the upward movement of the connecting ring 17 will drive the slag discharge plate 15 to move upwards through the connecting rod 16. At this time, the telescopic block 18 is not limited by the connecting ring 17 through the locking rod 20. It will retract into the groove of the flotation tank 4 through the reset action of the movable spring 19. Without the obstruction of the telescopic block 18, the slag discharge plate 15 can be pulled out from the inside of the flotation tank 4 through the connecting rod 16, so as to facilitate the collection and cleaning of the waste residue inside the slag discharge plate 15.

[0030] When the slag discharge plate 15 needs to be installed, simply connect the slag discharge plate 15 to the groove in the middle of the collection plate 14 through the connecting ring 17 and the connecting rod 16, and then pull the telescopic block 18 to one side, so that the telescopic block 18 drives the locking rod 20 and the protrusion 21 on one side to move to one side. When the connecting ring 17 moves to the top of the telescopic block 18, release the telescopic block 18. Under the reset action of the movable spring 19, the telescopic block 18 drives the protrusion 21 to move through the locking rod 20. At this time, the protrusion 21 can be inserted into the groove of the connecting ring 17, so that the slag discharge plate 15 can be fixed in the collection plate 14 through the connecting ring 17 and the connecting rod 16, so that the slag discharge plate 15 can be installed more stably in the collection plate 14.

[0031] See Figure 1 , Figure 2 , Figure 4 and Figure 6 It can be seen that when it is necessary to collect the waste residue inside the flotation tank 4, it is only necessary to pull the telescopic block 18 to one side so that the protrusion 21 does not limit the connecting ring 17. Then, the slag discharge plate 15 can be pulled out from the groove of the collection plate 14 through the connecting ring 17 and the connecting rod 16, so as to facilitate the collection and cleaning of the waste residue inside the flotation tank 4.

[0032] In summary: When using this electrocoagulation flotation equipment, the entire equipment can be placed in a stable position using the base 1. Wastewater is then injected into the electrocoagulant 2 through the inlet. The electrocoagulant 2 causes the waste residue and impurities in the wastewater to form flocs, which then flow through the pipe 3 into the flotation tank 4. Microbubble gas clusters are formed in the dissolved air tank 5 inside the flotation tank 4, allowing the microbubble gas clusters to come into contact with the flocs in the wastewater and form low-density flocs that float on the water surface. This facilitates the treatment of waste residue and impurities in the wastewater. This is existing technology and will not be elaborated further here. This is the characteristic of the use of this electrocoagulation flotation equipment. The content not described in detail in this description belongs to the prior art known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
