Background
The application of the coagulant in sewage treatment comprises the following steps: larger coarse suspended substances in the particles can be removed by natural sedimentation, but finer suspended substances, even some harmful chemical ions, especially colloid particles, settle slowly, can be kept in a dispersed suspended state in water for a long time and cannot naturally settle, and are difficult to separate and remove from the water by the natural sedimentation method. The principle of the coagulant is to destroy the stability of the fine particles, make them contact with each other to coagulate together, form floc, and sink and separate.
The coagulant preparation is generally carried out in a dissolving tank and a solution tank, the coagulant is firstly introduced into the dissolving tank, a small amount of water is added, the coagulant is dispersed and dissolved by using machinery, water conservancy or compressed air, then the dissolved medicine is sent into the dissolving tank to be diluted to a specified concentration, and the stirring is continuously carried out in the process.
The coagulant adding method comprises two steps: firstly, dry casting; the dry adding method is to directly add the powder coagulant into water, is suitable for adding a large amount of medicines, and can be used for lime hydrate, aluminum sulfate, ferric sulfate, ferrous sulfate and other medicines.

As shown in fig. 1, the lower end of the water shell 24 is connected with the lower end of the pre-dissolving barrel 9 through a hose, and the water shell 24 is connected with the hose through a rotary connecting structure; the reason why the rotary connection structure is adopted for connecting the water shell 24 and the hose connecting the water shell 24 and the pre-dissolving barrel 9 is that when the second motor 4 works, the second motor 4 can drive the connecting rotating shaft 26 to drive the water shell 24 to rotate, and the interference between the water shell 24 and the connected hose in the rotation process of the water shell 24 can be prevented through the rotary connection structure; according to the invention, when the water shell 24 rotates, the water shell 24 can drive the spraying pipes 25 arranged on the water shell to rotate, and the coagulant in each spraying pipe 25 can be further and better sprayed to each place of the sewage pool through designing the rotation of the spraying pipes 25.
As shown in fig. 12, the outer circumferential surface of the lower end of the connecting rotating shaft 26 has external threads, the threaded sleeve 27 has guide holes 33 uniformly distributed and penetrating in the circumferential direction, and the threaded sleeve 27 is mounted on the connecting rotating shaft 26 by means of thread fit with the external threads of the lower end of the connecting rotating shaft 26, as shown in fig. 11, a plurality of fixed guide rods 32 are uniformly mounted on the fixed support 23 in the circumferential direction, and the fixed guide rods 32 mounted on the fixed support 23 are slidably connected with the guide holes 33 of the threaded sleeve 27 in a one-to-one correspondence manner; as shown in fig. 12 and 13, each spraying pipe 25 is provided with a sliding block 28 in a sliding fit manner, each sliding block 28 is fixedly provided with a connecting rod 29, and one end of each connecting rod 29, which is far away from the corresponding sliding block 28, is arranged on the outer circular surface of the rotating sleeve which is rotatably matched with the threaded sleeve 27 in a hinged manner; when the connecting rotating shaft 26 is driven to rotate by the second motor 4, the threaded sleeve 27 is fixed by the fixed guide rods 32 and cannot rotate around the connecting rotating shaft 26, so that when the connecting rotating shaft 26 rotates, the threaded sleeve 27 can slide up and down relative to the connecting rotating shaft 26, the threaded sleeve 27 slides to drive the connecting rod 29 mounted on the threaded sleeve to swing, the connecting rod 29 swings to drive the corresponding sliding block 28 to swing, the sliding block 28 swings to drive the corresponding spraying pipe 25 to swing, namely, the spraying pipe 25 swings to and fro while rotating, the area range of the coagulant flowing out in the spraying pipe 25 is enlarged, and the contact efficiency of the coagulant and sewage is increased.
As shown in fig. 3, the second gear 10 is fixedly installed on the output shaft of the first motor 1, the first gear 6 is fixedly installed on the air pipe 7, and the first gear 6 is engaged with the second gear 10; the first motor 1 works to drive the second gear 10 to rotate, the second gear 10 rotates to drive the first gear 6 to rotate, and the first gear 6 rotates to drive the air pipe 7 to rotate, so that the coagulant in the pre-dissolving barrel 9 moves downwards.
As shown in fig. 5, a rectifying column 12 is fixedly installed at the lower end of the pre-dissolving barrel 9, which is located at the lower side of the barrel with smaller diameter, and the rectifying column 12 is provided with holes which are uniformly distributed and run through up and down; the rectifying column 12 is used for ensuring that high-pressure water flowing out of the pre-dissolving barrel 9 can stably flow out, and preventing the phenomenon of turbulent flow in a hose between the pre-dissolving mechanism 2 and the spraying mechanism 5 from causing flow loss of the high-pressure water and influencing the spraying effect.
As shown in fig. 5, the spiral stirring blade 11 is fixedly installed on the inner circular surface of the upper end of the barrel with smaller diameter at the lower side of the pre-dissolving barrel 9; the spiral stirring blade 11 is used for better enabling the coagulant mixed with the high-pressure water to be uniformly stirred.
As shown in fig. 6, the lower end surface of the watering ring shell 8 has water holes distributed uniformly, so as to ensure that high-pressure water can flow uniformly from the lower end of the watering ring shell 8 into the pre-dissolving tank 9, and a low-pressure backflow area is formed at the conical surface in the pre-dissolving tank 9.
The sum of the diameters of all the spray pipes 25 arranged at the upper end of the water shell 24 is equal to the pipe diameter of the lower end of the water shell 24 connected with a hose; the reason for this is to reduce the flow resistance and ensure that the coagulant which has become a solution flows from the hose connected to the lower end of the water jacket 24 into the individual spray pipes 25 with sufficient pressure.
The outer circle surface of the water adding ring shell 8 is provided with a water pipe 16, and the water pipe 16 is connected with an external high-pressure water source through a water pipe.
The diameter of the water delivery pipe 16 is equal to that of the barrel with smaller diameter at the lower side of the pre-dissolving barrel 9; in the invention, high-pressure water is sprinkled into the pre-dissolving barrel 9 from the water adding ring shell 8 and is mixed with the coagulant in the pre-dissolving barrel 9 to be changed into solution, the solution flows out through the lower side of the pre-dissolving barrel 9, the reason that the diameter of the water delivery pipe 16 is designed to be equal to the diameter of the barrel with smaller diameter at the lower side of the pre-dissolving barrel 9 is to reduce the flow resistance, and the coagulant which is changed into solution has enough pressure to flow out from the lower side of the pre-dissolving barrel 9.
The specific working process is as follows: when the sewage treatment device designed by the invention is used, firstly, a coagulant is added into the blanking pipe 13 through the hopper 3, then the coagulant is conveyed to the lower end of the blanking pipe 13 through the spiral conveying piece 15 arranged on the air pipe 7, and the coagulant enters the pre-dissolving barrel 9 under the blowing of high-pressure air in the air pipe 7; simultaneously, high-pressure water added into the water adding ring shell 8 is sprinkled into the pre-dissolving barrel 9 from the water adding ring shell 8 and is mixed with a coagulant in the pre-dissolving barrel 9 in a reflux zone, and the coagulant is changed into a solution; coagulant solution flows to the lower end of the pre-dissolving barrel 9 through the spiral stirring blade 11, flows into the water shell 24 through a hose connected between the pre-dissolving barrel 9 and the water shell 24, then the coagulant which becomes liquid flows into the spraying pipe 25 from the water shell 24, flows out from the spraying pipe 25, is mixed into the sewage pool to clean the sewage in the sewage pool.
