Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment equipment, and in particular to an automatic adding device and method for adding flocculants for urban and rural water supply. Background Art

[0002] Flocculant is the most basic and extremely important chemical powder in the treatment of industrial water and domestic sewage. By adding some flocculants into the water, the particles in the water that are difficult to precipitate can aggregate with each other to form a colloid, and then combine with the impurities in the water to form a larger floc. The floc has a strong adsorption capacity and can not only adsorb suspended matter, but also some bacteria and soluble substances. The flocculant increases in volume and sinks through adsorption.

[0003] Announcement No. CN 211664772 U discloses a flocculant adding device for a sludge treatment plant. The small pipe can be freely extended and retracted in the large pipe, thereby increasing the range of movement of adding flocculants. The third spring and the inclined plate in the fastening device are used to fix the small pipe, thereby increasing the stability of the small pipe. The spiral propulsion rods in the inner cavities of the large pipe and the small pipe are used to push the flocculant in the large pipe into the small pipe, thereby avoiding the blockage of the flocculant in the pipe, thereby realizing the automation of flocculant addition. The rotation of the two semicircular plates is used to drive the large pipe above the movable plate to move up, down, left, and right in a cyclic manner. The movable plate and the middle plate are connected by the second spring, and then the large pipe is connected by the middle plate by the support rod, thereby realizing the large pipe and the small pipe to move up, down, left, and right at the same time, thereby facilitating the discharge of the flocculant in the large pipe and the small pipe from the discharge port, thereby improving the efficiency of flocculant addition. However, the above patent still has the following problems in actual use:

[0004] When the flocculant adding equipment of the sludge treatment plant uses a spiral propeller to push and discharge the flocculant, it is not possible to achieve quantitative feeding of the flocculant, and it is not possible to accurately feed the flocculant. When the amount of flocculant is large, it will cause a waste of flocculant. When the amount of flocculant is small, it will affect the effect of sewage treatment. At the same time, it is not possible to achieve uniform delivery of the flocculant, which affects the effect of the reaction between the flocculant and sewage.

The heating spiral blade 110 can be used to dry the flocculant to avoid the flocculant from being damp and agglomerated. The second spiral blade 112 is driven to rotate by the mixing tripod 111 to break up the flocculant for easy discharge of the flocculant. The mixing rotating sleeve 109 is used to drive the sliding sleeve 114 to rotate. Under the limiting action of the sliding limiting block 115, the conical blocking block 116 drives the spiral clearing block 117 to rotate, thereby clearing the discharge port of the discharge box 101 to avoid the discharge port of the discharge box 101 being blocked, thereby affecting the normal discharge of the flocculant.

[0053] Secondly, the air pump 206 is used to inflate the interior of the lifting airbag 209, so that the lifting airbag 209 generates a certain buoyancy, thereby driving the scattering rotating disk 122 and the conical blocking block 116 to move up and down, so that the conical blocking block 116 is separated from the bottom discharge port of the discharge box 101, and the flocculant can fall into the scattering rotating disk 122 through the gap between the conical blocking block 116 and the discharge port, so as to evenly deliver the flocculant, and the opening and closing active bevel gear 214 is driven to rotate by the opening and closing motor 213, and the meshing connection between the opening and closing active bevel gear 214 and the meshing gear ring 215 and the opening and closing driven bevel gear 216 is utilized. The characteristics of the connection make the opening and closing connecting rod 217 drive the opening and closing baffle 218 to rotate, and by adjusting the size of the bottom opening of the air-inflating nozzle 211, the speed of the airflow outflow from the lifting airbag 209 can be controlled. When the air inside the lifting airbag 209 flows out, the lifting airbag 209 loses buoyancy, driving the conical blocking block 116 to descend, thereby controlling the speed of the discharge port of the discharge box 101. By controlling the lifting time of the lifting airbag 209, the amount of flocculant discharge is controlled to achieve the purpose of quantitative discharge. The air pump 206 is a prior art that can control the amount of inflation and the inflation pressure, thereby facilitating the quantitative addition of flocculant.

[0054] Finally, the rotating motor 120 drives the rotating connecting shaft 121 and the scattering rotating disk 122 to rotate, and the scattering rotating disk 122 and the scattering spiral blade 119 slide relative to each other to scatter the flocculant to the outside of the scattering rotating disk 122, and the flocculant falls through the through hole 123, so that the flocculant is evenly discharged, so that the flocculant can better contact with the sewage, thereby improving the sewage treatment effect, and the stirring driving gear 222 is driven by the stirring motor 221 to rotate, and the stirring driving gear 222 is meshed with the stirring driven gear 223 and the fixed gear ring 224. The mixing connecting rod 225 drives the stirring tripod 227 and the third spiral blade 228 to rotate, and the stirring driven gear 223 drives the stirring spiral blade 226 to rotate. When the stirring spiral blade 226 rotates, the stirring bracket 230 can be driven to rotate, so as to achieve sufficient mixing of the flocculant and the sewage. During the descent of the lifting airbag 209, bubbles will be generated from the air pumping nozzle 211. The bubbles can further make the sewage and the flocculant react, so as to purify the sewage. The sewage can be discharged through the drain pipe 203, and the flocculent precipitate can be discharged through the sewage pipe 204.

The mixing motor (105) is used to drive the rotating worm (106) to rotate. The rotating worm (106) and the rotating worm wheel (107) are meshed and connected to each other, so that the rotating worm wheel (107) drives the mixing rotating sleeve (109) to rotate. The heating spiral blade (110) is used to dry the flocculant to prevent the flocculant from agglomerating due to moisture. The material tripod (111) drives the second spiral blade (112) to rotate, which can break up the flocculant and facilitate the discharge of the flocculant. The mixing rotating sleeve (109) drives the sliding sleeve (114) to rotate. Under the limiting action of the sliding limiting block (115), the conical blocking block (116) drives the spiral clearing block (117) to rotate, thereby clearing the discharge port of the discharge box (101) to avoid blockage of the discharge port of the discharge box (101), thereby affecting the normal discharge of the flocculant. Step 2: Inflate the interior of the lifting airbag (209) by using an air pump (206) to generate a certain buoyancy in the lifting airbag (209), thereby driving the breaking up rotating disk (122) and the conical blocking block (116) to move upward and downward, so that the conical blocking block (116) is separated from the bottom discharge port of the discharge box (101), and the flocculant can fall into the breaking up rotating disk (122) through the gap between the conical blocking block (116) and the discharge port, thereby evenly dispensing the flocculant, and driving the opening and closing active bevel gear (214) to rotate by the opening and closing motor (213), and utilizing the opening and closing active bevel gear (214) to engage with the meshing gear ring (215) and the opening and closing driven bevel gear (216).

By adjusting the size of the bottom opening of the air pump (211), the speed of the airflow outflow from the lifting airbag (209) can be controlled. When the air inside the lifting airbag (209) flows out, the lifting airbag (209) loses buoyancy, driving the conical blocking block (116) to descend, thereby controlling the speed of the discharge port of the discharge box (101).

The stirring connecting rod (225) drives the stirring tripod (227) and the third spiral blade (228) to rotate, and the stirring driven gear (223) drives the stirring spiral blade (226) to rotate. When the stirring spiral blade (226) rotates, the stirring bracket (230) can be driven to rotate, thereby achieving full mixing of the flocculant and the sewage.
