Description

Technical Field

[0001] The invention belongs to the technical field of flocculant production equipment, and in particular relates to a flocculant preparation device for water treatment. Background Art

[0002] Flocculants for water treatment are chemical substances used to remove suspended matter from water. They can separate suspended matter from water by aggregating or precipitating it, thereby improving the clarity of water quality. Flocculants are widely used in industrial production, sewage treatment, drinking water purification and other fields. Common flocculants are mainly organic flocculants and inorganic flocculants. Before treating the water body, it is necessary to select an appropriate flocculant formula to configure the flocculant according to the specific conditions of the water body, and then add the selected flocculant to an appropriate amount of water, stir evenly to form a flocculant solution, and then adjust the concentration of the flocculant solution according to the water body to be treated. Usually, too high a concentration may cause excessive flocculation, and too low a concentration may not achieve the expected effect. Then adjust the pH value according to the water body to be treated, and finally put the prepared flocculant solution into the water body to be treated for use.

[0003] Conventional flocculant preparation usually uses a common stirring device, and the amount of each material added is manually controlled during the stirring process according to the specific water body to be treated, so as to prepare a flocculant that meets the needs.

[0037] Working principle: During operation, the solid materials to be prepared are first stored in the medicine storage hopper 211, and then water or other liquid materials to be prepared are stored in the first liquid storage tank 52 or the second liquid storage tank 53. At the beginning of preparation, the solid materials and the liquid materials need to be fed at the same time; At this time, the electric push rod 33 is started to drive the transmission component 34 to slide vertically on the stirring shaft 32, the first driving ring 341 is clamped on the first driven ring 23, and the third driving ring 343 is clamped on the second driven ring 42, and then the control motor 31 is started to reverse the control motor 31, and the stirring shaft 32 drives the first driven ring 23 and the second driven ring 42 to reverse at the same time. At this time, the first driven ring 23 is engaged with the medicine delivery disk 22, and the second driven ring 42 is engaged with the first dial ring 41; The rotation of the first driven ring 23 can drive the medicine delivery plate 22 to rotate, and the solid materials in the medicine storage hopper 211 fall into the medicine delivery groove 221 on the medicine delivery plate 22 when it rotates to the bottom of the medicine storage hopper 211. The medicine delivery groove 221 filled with solid materials falls into the mixing drum 1 when it rotates to the top of the discharge port 241 on the bottom plate 24, so that the fixed materials in the mixing drum 1 are fed. The feeding amount of the solid materials can be controlled by simply controlling the number of revolutions and angles of the stirring shaft 32. When the first dial ring 41 rotates, the dial rod 411 is driven to rotate. When the dial rod 411 rotates to the corresponding spray head 54, the switch on the spray head 54 can be turned to make the spray head 54 work and spray water or other liquid materials to realize the feeding of liquid materials in the mixing drum 1. The feeding amount of liquid materials can be controlled by simply controlling the number of revolutions and angles of the stirring shaft 32. When solid materials need to be fed separately due to configuration requirements during the flocculant preparation process, the electric push rod 33 is started, and the electric push rod 33 drives the transmission component 34 to rise, so that the second drive ring 342 is clamped on the first driven ring 23. At this time, the first drive ring 341 and the third drive ring 343 are not clamped on the second driven ring 42. At this time, the stirring shaft 32 is reversed, which can drive the drug delivery disc 22 to rotate, so as to realize the separate feeding of solid materials in the mixing drum 1; When the liquid material needs to be fed separately due to configuration requirements during the flocculant preparation process, the electric push rod 33 is started, and the electric push rod 33 drives the transmission component 34 to descend, so that the second drive ring 342 is clamped on the second driven ring 42. At this time, the first drive ring 341 and the third drive ring 343 are not clamped in the first driven ring 23. At this time, the stirring shaft 32 is reversed, which can drive the first dial ring 41 to rotate, so as to realize the separate feeding of the liquid material in the stirring drum 1; When feeding is not required during the flocculant preparation process, the control motor 31 drives the stirring shaft 32 to rotate forward. At this time, the first driven ring 23 is not engaged with the medicine delivery disk 22, and the second driven ring 42 is not engaged with the first shift ring 41. The stirring shaft 32 can drive the stirring blade 321 to rotate normally to stir and mix the materials in the stirring drum 1. After the flocculant is prepared, the prepared flocculant is discharged through the discharge port below the mixing drum 1, and the electric push rod 33 is started. The electric push rod 33 drives the transmission component 34 to descend, so that the second drive ring 342 is clamped on the second driven ring 42. At this time, the first drive ring 341 and the third drive ring 343 are not clamped in the first driven ring 23. At this time, the mixing shaft 32 is reversed, which can drive the first dial ring 41 to rotate. The rotation of the first dial ring 41 drives the lever 411 and the scraper 431 to rotate. The lever 411 first turns the switch on the corresponding spray head 54, so that the spray head 54 sprays water on the inner wall of the mixing drum 1, and then the scraper 431 cleans the inner wall of the mixing drum 1 that has been sprayed with water, effectively improving the cleaning effect.
