Description

Technical Field

[0001] The utility model relates to the technical field of coagulant dosing, and particularly relates to an automatic coagulant dosing device for a waterworks. Background Art

[0002] The automatic coagulant dosing device commonly used in waterworks is an important part of the water treatment system. It can automatically and accurately dose coagulants into raw water, promote the aggregation and precipitation of impurities such as suspended solids and colloids in the water, and improve the water quality. During the process of the water body entering the sedimentation tank for sedimentation, coagulants are usually sprayed through nozzles on one side of the inlet of the sedimentation tank and mixed with the water body for sedimentation.

[0003] According to the "Automatic Coagulant Dosing Device for a Waterworks" with the Chinese patent publication number CN215048934U, it mainly describes that by setting a motor, an incomplete gear and a ring rack, the coagulant is put into hopper A, then the motor is turned on to drive the incomplete gear to rotate, and then the ring rack will move horizontally. While the L-shaped plate reciprocates, the L-shaped plate will push the falling coagulant into hopper B and then fall into the reaction tank. Thus, the automatic quantitative addition of the coagulant can be achieved by controlling the motor. And by setting a slide bar, a filter screen and a handle, when it is necessary to disassemble and replace the filter screen, pull the handle to pull out the slide bar from the fixing groove, then take out the filter screen, and then replace and clean it. Then pull the handle, put the filter screen into the limit plate through the through groove, release the handle, and then the slide bar will enter the fixing groove, so that the filter screen is fixed, and thus the filter screen can be disassembled and then replaced and cleaned. During this process, the coagulant is concentrated on one side of the sedimentation tank and gradually moves with the water body. However, the moving speed of the water body is slow, resulting in poor mixing effect.

[0004] Therefore, an automatic coagulant dosing device for a waterworks is proposed to solve the problem that during this process, the coagulant is concentrated on one side of the sedimentation tank and gradually moves with the water body, but the moving speed of the water body is slow, resulting in poor mixing effect.

Detailed implementation manners

[0016] The present utility model will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figures 1-3 An automatic coagulant dosing device for a waterworks as shown, which includes a sedimentation tank 1, a guide groove 2 and a traveling crane 3. First motors are fixedly connected to both sides of the traveling crane 3, and the output ends of the first motors are fixedly connected to rotating rods 4. By driving the rotating rods 4 to rotate through the first motors, the traveling wheels 5 can move in the guide groove 2, thereby promoting the movement of the traveling crane 3. Traveling wheels 5 are fixedly connected to the rotating rods 4. A connecting cylinder 7 is fixedly connected to the center of the upper end of the traveling crane 3. A second motor is fixedly connected to one side of the connecting cylinder 7, and the output end of the second motor is fixedly connected to a flap 13. By driving the flap 13 to rotate through the second motor, the coagulant can enter the feeding port 8 from the storage cylinder 6. A storage cylinder 6 is fixedly connected to the upper end of the connecting cylinder 7. A feeding port 8 is fixedly connected to the bottom end of the traveling crane 3 and the feeding port 8 communicates with the storage cylinder 6. A third motor is fixedly connected to one side of the traveling crane 3, and the output end of the third motor is fixedly connected to a driving gear 9. An auxiliary gear ring 10 is engaged with one side of the driving gear 9. The auxiliary gear ring 10 is rotatably connected to the bottom end of the traveling crane 3. A rotating cylinder 11 is fixedly connected to the bottom end of the auxiliary gear ring 10. A connecting plate 12 is fixedly connected to the bottom end of the rotating cylinder 11. Through holes are evenly formed in the bottom end of the rotating cylinder 11. By driving the driving gear 9 to rotate through the third motor, the auxiliary gear ring 10 can be driven to rotate, thereby driving the rotating cylinder 11 to rotate. At this time, the coagulant falls onto the connecting plate 12 and is evenly dispersed from the through holes, so as to achieve the effect of mobile automatic dosing of the coagulant.

[0018] Among them, the rotating rod 4 contacts the spherical ball 15. The spherical ball 15 is rotatably embedded in the groove. The groove is located at the bottom end of the vertical rod 14. The vertical rod 14 is fixedly connected to the four sides of the bottom end of the traveling vehicle 3. By providing the vertical rod 14 and the spherical ball 15, support can be provided on one side of the rotating rod 4, thereby promoting the stable rotation of the rotating rod 4.

[0019] Among them, a synchronous belt 16 is arranged at the annular depression. The synchronous belt 16 is sleeved on two adjacent rotating rods 4. The annular depression is located on the rotating rod 4. By providing the synchronous belt 16, the stable movement of the traveling wheels 5 can be promoted.

[0020] Among them, the guide groove 2 corresponds to the scraper 18. The scraper 18 is fixedly connected to one side of the support rod 17. The four support rods 17 are fixedly connected to the bottom side of the traveling vehicle 3. By providing the scraper 18, the guide groove 2 can be cleaned when the traveling vehicle 3 moves, avoiding instability when the traveling vehicle 3 moves.

[0021] Among them, the grooves are located on the upper and lower sides of the baffle 20. The baffle 20 is fixedly connected between the two connecting rods 19. The connecting rod 19 is arranged between the two support rods 17. The two connecting rods 19 are fixedly connected to the bottom end of the traveling vehicle 3. By providing the baffle 20 and the grooves on the baffle 20, when the traveling vehicle 3 drives the connecting rod 19 and the baffle 20 to move, the grooves can comb the water body, thereby promoting the mixing of the coagulant and the water body.

[0022] Working principle: When a coagulant needs to be added to the water body, the first motor controls the rotation of the rotating rod 4, thereby promoting the rotation of the traveling wheels 5 and causing the traveling vehicle 3 to move on the upper side of the sedimentation tank 1. At this time, the coagulant enters the feeding port 8 from the storage cylinder 6 and then gradually falls on the connecting plate 12. At this time, the third motor drives the driving gear 9 to rotate and causes the auxiliary gear ring 10 to rotate. At this time, the rotating cylinder 11 rotates, and under the action of centrifugal force, the coagulant is dispersed in a fountain shape from the through holes and falls on the water body. When the traveling vehicle 3 moves, it can drive the connecting rod 19 and the baffle 20 to move. The baffle 20 is below the water surface of the water body. The grooves on the baffle 20 can cause the water body to generate turbidity, thereby achieving the effect of promoting the mixing of the flocculant.

[0023] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
