Description

Technical Field

[0001] The present application relates to the field of wastewater treatment technology, and more particularly to a concrete wastewater flocculation tank. Background Art

[0002] A large amount of wastewater is generated during the production process of concrete. The wastewater contains a large amount of strong alkaline substances such as cement, sand, coal powder, ash, mineral powder, admixtures, etc. Direct discharge will cause serious pollution to the environment. Therefore, it is necessary to filter, flocculate and filter press the concrete wastewater.

[0003] In the coagulation and flocculation tank, through slow movement and sufficient stirring, the flocculant comes into contact with the suspended matter and colloidal substances in the water, so that they are flocculated into flocs. The tank is usually equipped with a stirring device or a flotation device to increase the flocculation speed. The flocs after coagulation will gradually sink to the bottom of the tank to form a sludge layer, and the clean water flows into the sedimentation tank from the top.

[0004] When the existing wastewater flocculation tank is in use, the wastewater and flocculant are mostly stirred by rotating the stirring shaft driven by a motor. However, during the mixing process, due to the stickiness of the flocculant, part of the flocculant is easily attached to the inner wall of the flocculation tank and is not easy to mix with the wastewater. The rotation direction of the stirring shaft is relatively single, which can easily affect the mixing of the flocculant and the wastewater. Utility Model Content

[0005] The purpose of the present application is to solve the problem that flocculants are easily attached to the inside of the flocculation tank, and the present application provides a concrete wastewater flocculation tank.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0008] By adopting the above technical solution, the motor drives the stirring mechanism to stir the wastewater and flocculant, reducing the flocculant adhering to the inner wall of the tank body, facilitating the mixing of the wastewater and flocculant, and further reducing the impact on wastewater flocculation.

[0010] By adopting the above technical solution, the transmission component is used to rotate the stirring rod one and the stirring rod two, and the stirring blades rotate alternately, so that the flocculant and the wastewater are merged.

[0012] By adopting the above technical solution, the motor rotates, so that gear one drives gear two and gear three to rotate. The diameter of gear two is larger than that of gear three, so that the rotation speeds of stirring rod one and stirring rod two are different. Gear one drives stirring rod three to stir and scrape the inner wall of the pool body, thereby reducing the attachment of flocculant to the inner wall of the pool body, facilitating the mixing of flocculant and wastewater, and reducing the impact on wastewater flocculation.

[0013] Furthermore, the stirring blade is provided with stirring holes, and the stirring holes are distributed in a straight line array.

[0014] By adopting the above technical solution, the stirring hole reduces the resistance between the stirring blade and the wastewater, so that the flocculant and the wastewater are mixed.

[0015] Furthermore, protective nets are provided on both sides of the support plate, and the protective nets are fixedly connected to the pool body and the support plate.

[0016] By adopting the above technical solution, the protective net reduces the risk of workers falling into the pool.

[0017] Furthermore, a feed pipe is fixed to the upper end of the feed pipe, one end of the feed pipe away from the feed pipe is fixedly connected to a water outlet of a water pump, a water inlet is fixed to the side of the water pump, and a nozzle is fixed to the lower end of the feed pipe and distributed in an array.

[0018] By adopting the above technical solution, the nozzle allows the prepared flocculant to contact and mix with the wastewater in the water inlet pipe in advance, and sprays it evenly in the wastewater, so that the flocculant and the wastewater are mixed in advance.

[0019] Furthermore, one end of the water inlet pipe extending into the pool body is threadedly connected with a filter tube, and a filter screen is fixed in the filter tube.

At the same time, the stirring blades on stirring rod 1 and stirring rod 2 rotate alternately. When rotating, the stirring holes reduce the resistance between the stirring blades and the wastewater, which is convenient for mixing flocculant and wastewater and reduces the impact on wastewater flocculation.

DETAILED DESCRIPTION

[0032] The following is combined with Figures 1 to 4 This application is described in further detail.

[0033] The embodiment of the present application discloses a concrete wastewater flocculation tank.

[0034] Reference Figure 1 A concrete wastewater flocculation tank comprises a tank body 1, a water inlet pipe 2 is fixed on the side of the tank body 1, a support plate 4 is fixed on the tank body 1, a motor 5 is fixed on the support plate 4, the output end of the motor 5 passes through the support plate 4, a feed pipe 6 is fixed at one end of the support plate 4, the feed pipe 6 passes through the support plate 4 and extends into the tank body 1, and a stirring mechanism is arranged at the output end of the motor 5.

[0035] When treating concrete wastewater, the staff discharges the wastewater into the tank body 1 through the water inlet pipe 2, and then adds the configured flocculant into the tank body 1 through the discharge pipe 6, and then drives the stirring mechanism through the motor 5 to stir the wastewater and the flocculant, so as to reduce the flocculant adhering to the inner wall of the tank body, facilitate the mixing of the wastewater and the flocculant, and thus reduce the impact on the flocculation of the wastewater.

[0036] Reference Figure 2 and Figure 3 The stirring mechanism includes a stirring rod 10 and a stirring rod 2 11 which are rotatably connected to the lower end of the support plate 4. The stirring rod 10 and the stirring rod 2 11 are fixedly connected with stirring blades 12 and are arranged in an array. The stirring blades 12 on the stirring rod 10 and the stirring rod 2 11 are staggered. The upper ends of the stirring rods 10 and the stirring rods 2 11 are provided with a transmission assembly. The transmission assembly includes a gear 1 7 fixed to the output end of the motor 5. The lower end of the gear 1 7 is fixed with a stirring rod 3 21. The stirring rod 3 21 is L-shaped. A scraper 22 is fixed at one end of the stirring rod 3. The scraper 22 contacts the inner wall of the tank body. The upper end of the stirring rod 10 is fixedly connected with a gear 2 8. The upper end of the stirring rod 2 11 is fixedly connected with a gear 3 9. The gear 1 7 is meshed with the gear 2 8 and the gear 3 9. The stirring blade 12 is provided with a stirring hole 13, and the stirring holes 13 are arranged in a straight line array.

[0037] When treating concrete wastewater, the motor 5 is turned on, and the motor 5 drives the gear 1 7 to rotate, and the gear 1 7 drives the gear 2 8 and the gear 3 9 to rotate. The rotation directions of the gear 1 7, the gear 2 8 and the gear 3 are different. The gear 1 7 drives the stirring rod 3 21, and the stirring rod 3 21 drives the scraper to scrape the flocculant attached to the inner wall of the pool body 1, so that the scraped flocculant is mixed with the wastewater. At the same time, the stirring rod 10 and the stirring rod 2 11 are rotated. During the rotation, the diameter of the gear 2 8 is larger than the gear 3 9, so that the rotation speed of the stirring rod 10 and the stirring rod 2 11 is different, which improves the mixing of the flocculant and the wastewater. At the same time, the stirring blades 12 on the stirring rod 10 and the stirring rod 2 11 rotate alternately. During the rotation, the stirring hole 13 reduces the resistance between the stirring blade 12 and the wastewater, and reduces the attachment of the flocculant to the inner wall of the pool body through the stirring mechanism, which is convenient for mixing the flocculant and the wastewater and reduces the influence on the flocculation of the wastewater.

[0038] Reference Figure 2 and Figure 4, protective nets 14 are provided on both sides of the support plate 4, and the protective nets 14 are fixedly connected to the tank body 1 and the support plate 4. A feed pipe 16 is fixed to the upper end of the feed pipe 6, and the end of the feed pipe 16 away from the feed pipe 6 is fixedly connected to the water outlet end of the water pump 15, and the side of the water pump 15 is fixed with a water inlet end, and the lower end of the feed pipe 6 is fixed with a nozzle 18 and distributed in an array. The end of the water inlet pipe 2 extending into the tank body 1 is threadedly connected with a filter pipe 19, and a filter screen 20 is fixed in the filter pipe 19. A water outlet pipe 3 is fixed on one side of the tank body 1, and a solenoid valve 17 is fixed in the water outlet pipe 3.

[0039] When treating concrete wastewater, the protective net 14 reduces the risk of workers falling into the tank body 1. At the same time, the water pump 15 is turned on, and the prepared flocculant enters the water outlet from the water inlet end through the water pump 15. The feed pipe 16 enters the discharge pipe 6, and the prepared flocculant is contacted and mixed with the wastewater in the water inlet pipe 2 through the nozzle 18, and is evenly sprayed in the wastewater to mix the flocculant and the wastewater in advance. When the wastewater enters the tank body 1, the filter screen 20 simply filters the sand and gravel debris in the wastewater to improve the water quality. When replacing, the filter tube 19 can be twisted to clean and replace the filter screen 20. After the mixing is completed, the wastewater is discharged through the outlet pipe 3, and the speed of water discharge is controlled by the solenoid valve 17 to facilitate the next step of sedimentation.

[0040] The implementation principle of a concrete wastewater flocculation tank in this embodiment is as follows: when treating concrete wastewater, the protective net 14 reduces the risk of workers falling into the tank body 1, and the workers discharge the wastewater into the tank body 1 through the water inlet pipe 2. When draining, the filter screen 20 simply filters the sand and gravel debris in the wastewater. When replacing, the filter tube 19 can be twisted to clean and replace the filter screen 20. At the same time, the water pump 15 is turned on, and the prepared flocculant enters the water outlet from the water inlet end through the water pump 15, and enters the discharge pipe 6 through the feed pipe 16. The prepared flocculant is contacted and mixed with the wastewater from the water inlet pipe 2 in advance through the nozzle 18, and is evenly sprayed in the wastewater. After completion;

[0041] Turn on the motor 5, the motor 5 drives the gear 1 7 to rotate, the gear 1 7 drives the gear 2 8 and the gear 3 9 to rotate, the gear 1 7 rotates in different directions from the gear 2 8 and the gear 3, the gear 1 7 drives the stirring rod 3 21 to scrape the flocculant attached to the inner wall of the pool body 1, and the scraped flocculant is mixed with the wastewater. At the same time, the stirring rod 10 and the stirring rod 2 11 are rotated. During the rotation, the diameter of the gear 2 8 is larger than the gear 3 9, so that the rotation speed of the stirring rod 10 and the stirring rod 2 11 is different, which improves the mixing of the flocculant and the wastewater. At the same time, the stirring blades 12 on the stirring rod 10 and the stirring rod 2 11 rotate alternately. During the rotation, the stirring holes 13 reduce the resistance between the stirring blades 12 and the wastewater, and the flocculant is reduced from adhering to the inner wall of the pool body through the stirring mechanism. After the stirring is completed, the wastewater is discharged through the outlet pipe 3, and the speed of discharging water is controlled by the solenoid valve 17 to facilitate the next step of sedimentation.
