Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a flocculant adding device for wastewater treatment. Background Art

[0002] Flocculants are chemicals used in water treatment that help suspended matter, colloidal substances, and turbid substances in water quickly aggregate into larger clumps (called floccules) so that they can be more easily separated from the water. The mechanism of action of flocculants includes changing the surface charge of suspended matter, neutralizing the charge and forming floccules, and promoting the growth and aggregation of floccules. Common flocculants include inorganic flocculants (such as ferric chloride and aluminum chloride) and organic flocculants (such as polyaluminum chloride and polyacrylamide). Flocculants play an important role in purifying water quality and improving water treatment efficiency in water treatment. They are often used in sewage treatment, drinking water purification, industrial wastewater treatment and other fields.

[0003] At present, in the process of wastewater treatment, flocculants are basically added by manual throwing, which is easy to cause the problem of excessive addition. Too much flocculant will cause excessive agglomeration of particles and microparticles in the wastewater to form large pieces of matter. The sedimentation rate of these large pieces of matter may slow down, making it difficult to completely remove them from the water. Instead, they are likely to form solid wastes such as sediment and sludge, increasing the difficulty and time of subsequent treatment. In addition, flocculants are generally directly thrown into the wastewater, and the wastewater and flocculants are not dissolved and mixed thoroughly, which is also easy to cause waste of flocculants. In view of the above problems, a flocculant addition device for wastewater treatment is proposed to solve them. Utility Model Content

[0004] In order to solve the above technical problems, a flocculant adding device for wastewater treatment is provided, which solves the problem that the current wastewater treatment process is basically done by manual throwing and adding flocculants, which is easy to cause excessive addition. Excessive flocculants will cause excessive aggregation of particles and microparticles in the wastewater to form large pieces of matter. The sedimentation rate of these large pieces of matter may slow down, making it difficult to completely remove them from the water. Instead, they are likely to form solid wastes such as sediment and sludge, increasing the difficulty and time of subsequent treatment. In addition, flocculants are generally directly thrown into the wastewater, and the wastewater and flocculants are not dissolved and mixed thoroughly, which is also likely to cause the problem of waste of flocculants.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a flocculant adding device for wastewater treatment, including a solvent box, a rotating shaft is rotatably connected inside the solvent box, a first stirring frame is fixedly connected to the upper and lower sides of the rotating shaft, a second stirring frame is fixedly connected to the front and rear sides of the rotating shaft, a feed pipe is fixedly connected to the center position of the bottom of the solvent box, a volume tube is fixedly connected to the bottom of the feed pipe, a second solenoid valve is fixedly installed inside the volume tube near the outlet position, an adjusting piston is slidably connected to the right side of the volume tube, a connecting rod is fixedly connected to the right side of the adjusting piston, the end of the connecting rod passes through the right side wall of the volume tube and extends to the outside of the volume tube, and an adjustment component is arranged at the bottom of the solvent box and the right side of the volume tube.

[0006] Preferably, the regulating assembly comprises a regulating box body and a right-angle connector, the regulating box body is fixedly connected to the bottom of the solvent box via the right-angle connector, and a through groove is formed through the bottom of the regulating box body.

[0008] Preferably, an adjusting motor is fixedly mounted on the right side of the adjusting box body, and an output end of the adjusting motor passes through the right side wall of the adjusting box body and is fixedly connected to the right end of the threaded rod.

[0009] Preferably, a liquid pump is fixedly installed on the right side of the top of the solvent box, and the output end of the liquid pump is connected to the inside of the solvent box through a connecting pipe.

[0011] Preferably, a first solenoid valve is fixedly installed inside the discharge pipe.

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] The utility model is provided with an adjusting motor to drive the threaded rod to rotate, so that the moving seat moves left and right along the length direction of the threaded rod. When the moving seat moves to the left, the adjusting piston is pushed to move to the left by the connecting rod, so that the volume inside the volume tube is reduced. Similarly, when the moving seat moves to the right, the volume inside the volume tube is increased. By controlling the amount of flocculant added by the above scheme, it can be ensured that the amount of flocculant added is not excessive. The appropriate amount of flocculant added can effectively promote the coagulation and sedimentation of suspended particles in the wastewater, thereby significantly improving the efficiency and quality of wastewater treatment. This helps to reduce the content of impurities and pollutants in the wastewater to meet the discharge standard or reuse standard. Accurately controlling the amount of flocculant added can avoid excessive use of flocculants, thereby reducing the waste of agents. This can not only reduce the cost of wastewater treatment, but also help to achieve the rational use of resources.

[0014] The utility model performs dissolution pretreatment on the flocculant through a solvent box, a stirring motor, a rotating shaft, a first stirring frame and a second stirring frame. This method can make the flocculant more evenly dispersed in the entire wastewater. This uniform dispersion helps the flocculant to fully contact and mix with the suspended particles in the wastewater, thereby improving the flocculation effect. By dissolving first and then adding, the amount of flocculant can be more accurately controlled. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Specifically, the adjustment component 14 includes an adjustment box body 1401 and a right-angle connector 1402. The adjustment box body 1401 is fixedly connected to the bottom of the solvent box 1 through the right-angle connector 1402. A through groove 1408 is opened through the bottom of the adjustment box body 1401. The right-angle connector 1402 is fixed to the bottom of the solvent box 1 with screws. There are four right-angle connectors 1402 in total, which are respectively arranged at the four corners of the adjustment box body 1401.

[0025] It is worth noting that the upper part of the regulating box body 1401 is rotatably connected with a threaded rod 1403, the lower part of the regulating box body 1401 is fixedly connected with a limiting rod 1404, the surface of the threaded rod 1403 is threadedly connected with a moving seat 1405, the inside of the moving seat 1405 is slidably connected with the surface of the limiting rod 1404, the bottom of the moving seat 1405 passes through the through slot 1408 and is fixedly connected with a connecting plate 1406, the connecting plate 1406 is fixedly connected with the right end of the connecting rod 13, and the amount of flocculant added is controlled by the regulating component 14, which can ensure the stable operation of the treatment process. This helps to reduce process fluctuations and failures caused by improper addition and improve the reliability of the entire wastewater treatment system.

[0026] Specifically, an adjusting motor 1407 is fixedly installed on the right side of the adjusting box body 1401, and the output end of the adjusting motor 1407 passes through the right side wall of the adjusting box body 1401 and is fixedly connected to the right end of the threaded rod 1403.
