Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an indirect suction type flocculant dosing device. Background Art

[0002] According to their chemical composition, flocculants can be generally divided into two categories: inorganic flocculants and organic flocculants. Inorganic flocculants include inorganic coagulants and inorganic polymer flocculants, and organic flocculants include synthetic organic polymer flocculants, natural organic polymer flocculants and microbial flocculants. In the field of water treatment for water supply and drainage, it is often necessary to add flocculants to the treated water to condense certain tiny suspended impurities in the water for easy removal;

[0003] In the prior art, flocculating agents are usually added before a water pump, and the negative pressure of the water pump suction port is used to suck the prepared flocculating agents into the water. The high-speed rotation of the water pump impeller can quickly mix the agents and water. However, for water pumps with a low suction range, due to the low efficiency of the water pump, there are shortcomings such as unstable liquid suction volume, uneven mixing of the agents and water, and inaccurate liquid metering, resulting in poor impurity coagulation effect. Therefore, the utility model proposes an indirect suction flocculant dosing device to solve the above problems. Utility Model Content

[0004] In view of the above problems, the utility model proposes an indirect suction flocculant dosing device to solve the problem in the prior art that when a water pump is used to add flocculant, the flocculant is easily affected by the power of the water pump and the suction volume is unstable.

[0007] A further improvement is that a No. 1 motor is installed on the left side of the bottom of the main frame, the output end of the No. 1 motor is connected to the bottom of the turntable, and the outer wall of the piston is fitted and connected to the inner wall of the feeding pipe.

[0008] A further improvement is that electromagnetic valves are provided at the top and bottom of the discharge pipe, a No. 2 motor is installed at the top of the storage hopper, and a stirring mechanism is provided inside the storage hopper.

[0009] A further improvement is that the stirring mechanism includes a rotating shaft and stirring blades, the rotating shaft is rotatably connected to the upper part of the storage hopper, the top of the rotating shaft is connected to the output end of the second motor, and multiple groups of stirring blades are symmetrically arranged on the outer center of the rotating shaft.

Because the connecting rod is hinged with the movable rod, and the feeding tube can only limit the movable rod to make linear motion, the movable rod drives the piston to make linear reciprocating motion on the inner wall of the feeding tube, repeatedly exhausting the air inside the feeding tube, and using the air pressure difference to suck the flocculant powder inside the storage hopper into the inside of the feeding tube, and then the flocculant powder is pushed into the internal gap of the discharge tube through the piston to be fed outward, and each time the movable rod moves to a constant power and a constant size of the feeding tube, so that the amount of medicine added each time is stable.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes an indirect suction flocculant dosing device, including a main frame 1, a fixed frame 2 and a storage hopper 3. The fixed frame 2 is fixed on the right side of the main frame 1, and the storage hopper 3 is installed on the top of the fixed frame 2. One side of the top of the storage hopper 3 is connected with a feeding pipe 4, and the bottom end of the storage hopper 3 is connected with a discharge pipe 5. The outer side of the discharge pipe 5 is connected with a feeding pipe 6. A suction dosing mechanism matching the feeding pipe 6 is provided on the left side of the main frame 1. The flocculant powder is poured into the storage hopper 3 through the feeding pipe 4 for storage. When dosing is needed, the suction dosing mechanism sucks the flocculant powder into the feeding pipe 6 to ensure the dosage for sewage treatment, and then pushes the flocculant powder into the discharge pipe 5, and discharges it to the outside through the discharge pipe 5. The volume of the feeding pipe 6 is fixed, so its dosing amount is fixed, so that the impurity coagulation effect is stable.

[0019] The suction-type dosing mechanism includes a turntable 7, a movable rod 8, a piston 9, an articulated seat 10, a connecting rod 11 and a pin 12. The left side of the main frame 1 is rotatably connected to the turntable 7, and the right end of the feeding tube 6 is slidably installed with the movable rod 8. One end of the movable rod 8 is connected to the piston 9, and the left end of the movable rod 8 is connected to the articulated seat 10. One end of the articulated seat 10 is hinged to the connecting rod 11. The outer side of the turntable 7 is hinged to the left end of the connecting rod 11 through the pin 12. The left end of the feeding tube 6 is provided with a vent. A No. 1 motor 13 is installed on the left side of the bottom of the main frame 1. The output end of the No. 1 motor 13 is connected to the bottom of the turntable 7. The outer wall of the piston 9 is connected to the The inner wall of the feeding tube 6 is fitted and connected, and the No. 1 motor 13 drives the turntable 7 to rotate on the left side of the main frame 1. The turntable 7 drives the connecting rod 11 to make a circular motion through the pin shaft 12. Because the connecting rod 11 is hinged with the movable rod 8, and the feeding tube 6 can only limit the movable rod 8 to make a linear motion, the movable rod 8 drives the piston 9 to make a linear reciprocating motion on the inner wall of the feeding tube 6, repeatedly exhausting the air inside the feeding tube 6, and using the air pressure difference to suck the flocculant powder inside the storage hopper 3 into the inside of the feeding tube 6, and then the flocculant powder is pushed into the internal gap of the discharge tube 5 through the piston 9 to be fed outward, and each time the movable rod 8 moves to a constant power and a constant size of the feeding tube 6, the amount of medicine added each time is stable.

[0020] The top and bottom ends of the feed pipe 5 are both provided with solenoid valves 14. When the flocculant powder inside the storage hopper 3 is sucked, the solenoid valve 14 at the top end of the feed pipe 5 is opened, and the solenoid valve 14 at the bottom end of the feed pipe 5 is closed, and the passage between the feeding pipe 6 and the storage hopper 3 is opened. When the flocculant powder inside the feeding pipe 6 needs to be discharged into the feed pipe 5, the solenoid valve 14 at the top end of the feed pipe 5 is closed, and the solenoid valve 14 at the bottom end of the feed pipe 5 is opened, and the passage between the feeding pipe 6 and the storage hopper 3 is closed, and the passage at the bottom of the feed pipe 5 is opened.

[0021] A No. 2 motor 17 is installed on the top of the storage hopper 3, and a stirring mechanism is provided inside the storage hopper 3. The stirring mechanism includes a rotating shaft 18 and stirring blades 19. The upper part of the storage hopper 3 is rotatably connected with the rotating shaft 18, and the top of the rotating shaft 18 is connected to the output end of the No. 2 motor 17. A plurality of stirring blades 19 are symmetrically provided on the outer center of the rotating shaft 18. The No. 2 motor 17 can drive the rotating shaft 18 to rotate inside the storage hopper 3, and the rotating shaft 18 can drive the stirring blades 19 to stir the flocculant powder inside the storage hopper 3 to move it, so as to break it up and avoid excessive flocculant powder from piling up and being unable to be discharged.

[0022] A hose 15 is sleeved on the bottom end of the discharge pipe 5, and a clamp 16 is provided on the top end of the hose 15. Both ends of the clamp 16 are detachably connected by bolts. The clamp 16 is sleeved on the outer side of the top end of the hose 15, and the top end of the hose 15 is directly sleeved on the bottom end of the discharge pipe 5. Then, the bolts at both ends of the clamp 16 are tightened to drive the clamp 16 to shrink inward to clamp the top end of the hose 15 on the bottom end of the discharge pipe 5. At this time, the top end of the hose 15 and the bottom end of the discharge pipe 5 are connected to each other, and the hose 15 can extend the discharge distance of the discharge pipe 5, making the discharge of the flocculant powder more convenient.

The two flanges are detachably connected to the left side of the bottom of the main frame 1 and the top of the storage hopper 3 by bolts.

[0024] In the indirect suction flocculant dosing device, the No. 1 motor 13 drives the turntable 7 to rotate on the left side of the main frame 1, and the turntable 7 drives the connecting rod 11 to make a circular motion through the pin shaft 12. Because the connecting rod 11 is hinged with the movable rod 8, and the feeding tube 6 can only limit the movable rod 8 to make a linear motion, the movable rod 8 drives the piston 9 to make a linear reciprocating movement on the inner wall of the feeding tube 6, repeatedly evacuating the air inside the feeding tube 6, and using the air pressure difference to suck the flocculant powder inside the storage hopper 3 into the inside of the feeding tube 6, and then the flocculant powder is pushed into the internal gap of the discharge tube 5 through the piston 9 to be fed outward, and each time the movable rod 8 moves to a constant power and a constant size of the feeding tube 6, the amount of medicine added each time is stable.
