Description

Technical Field

[0001] This utility model belongs to the technical field of wastewater treatment equipment, specifically a mixing device for purifying agents in a fly ash solidification wastewater treatment tank. Background Technology

[0002] With the development of industry, the treatment of wastewater generated during the solidification process of fly ash has become an important issue in the field of environmental protection. The wastewater from fly ash solidification is complex and contains various pollutants such as heavy metals and organic matter, requiring the addition of purification agents for treatment.

[0003] Fly ash solidification wastewater contains various pollutants, such as heavy metal ions and organic matter. Purification agents typically contain multiple chemical components, such as flocculants, precipitants, and neutralizers. Through a mixing device, the purifying agent can be fully contacted and uniformly mixed with the wastewater, allowing the various components in the purifying agent to rapidly react chemically with the pollutants in the wastewater. For example, flocculants can coagulate suspended solid particles into larger particles, facilitating subsequent sedimentation and separation; neutralizers can adjust the pH of the wastewater to a suitable treatment range, creating favorable conditions for other purification reactions.

[0004] In existing technologies, long-term use and observation have revealed that existing tanks generally do not have baffle structures. Without the obstruction and guidance of baffles, the fluid inside the tank tends to form a fixed flow path, and the flow becomes slow or even stagnant in the corners or edges of the tank. The fluid in these dead zones cannot fully participate in mixing, resulting in uneven overall mixing. Therefore, a fly ash solidification wastewater treatment tank purification agent mixing device is proposed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figure 1 - Figure 4This utility model provides a mixing device for a fly ash solidification wastewater treatment tank purification agent, including a mixing tank 1; multiple sets of support legs 10 are fixedly connected to the bottom end of the mixing tank 1; a cover 11 is provided at the top end of the mixing tank 1; feed inlets 101 are symmetrically fixedly connected to the side walls of the cover 11; support rods 12 are symmetrically fixedly connected to the top end of the cover 11; a servo motor 13 is fixedly connected to the side wall of the support rod 12; a rotating shaft 14 is fixedly connected to the output end of the servo motor 13; the rotating shaft 14 passes through the surface of the cover 11 and is rotatably connected to it; multiple sets of first stirring rods 15 are symmetrically fixedly connected to the side wall of the rotating shaft 14; the first stirring rods 15 are arc-shaped. The mixing tank 1 is configured in a symmetrical shape; multiple sets of second stirring rods 16 are symmetrically fixed to the side wall of the rotating shaft 14; the second stirring rods 16 are inclined; multiple sets of support blocks 17 are fixed to the side wall of the mixing tank 1; a baffle body 18 is slidably connected to the side wall of the support block 17; during operation, the mixing tank 1 is supported by the support legs 10, and the mixing tank 1 is supported by the cover 11. The operator can add wastewater and purification agent through the feed inlet 101. After the addition is completed, the servo motor 13 is supported by the support rod 12. The operation of the servo motor 13 drives the rotating shaft 14 to rotate, and the rotation of the rotating shaft 14 drives the first stirring rod. The first stirring rod 15 rotates, and the ribbon-type impeller used in the first stirring rod 15 may generate some high-viscosity substances or suspensions during the mixing process. The ribbon-type impeller is suitable for high-viscosity liquids of 200-500 Pa·s and pseudo-plastic fluids. It can fully mix the purifying agent with wastewater, fly ash, etc. through axial and radial composite flow in laminar flow state, improving the mixing uniformity. At the same time as the rotating shaft 14 rotates, it can also drive the second stirring rod 16 to rotate. The straight-blade impeller used in the second stirring rod 16 mainly generates radial flow, which can better disperse the purifying agent in the radial direction, which helps to mix with the wastewater. Water and fly ash come into rapid contact within a certain range, accelerating the initial mixing process. The support block 17 supports the baffle body 18, which changes the fluid flow direction during mixing, increasing the fluid turbulence. This design is not only simple and convenient to operate, but also prevents the fluid from forming a single circulation path and avoids dead zones, allowing the fluid to form a complex flow field within the tank, thereby promoting thorough mixing of the purifying agent and wastewater. Furthermore, the structure of the first stirring rod 15 and the second stirring rod 16 further enhances the mixing effect and treatment efficiency of the purifying agent and materials in the fly ash solidification wastewater treatment tank.

[0026] Furthermore, such as Figure 1 - Figure 4As shown, a first support plate 2 is symmetrically fixed to the side wall of the cover 11; a second support plate 21 is symmetrically fixed to the side wall of the mixing tank 1; an insertion hole 22 is provided on the side wall of the first support plate 2; the insertion hole 22 is also provided on the side wall of the second support plate 21; a fixing bolt 23 is provided inside the insertion hole 22; a fixing nut 24 is provided in the middle of the fixing bolt 23; the fixing nut 24 and the fixing bolt 23 are connected by a threaded connection; a sealing ring 25 is fixed to the side wall of the cover 11; during operation, the first support plate 2 and the second support plate 21 are connected by a threaded connection. The support plate 21 provides support. The worker inserts the fixing bolt 23 into the insertion hole 22. After the fixing bolt 23 has completely passed through the surface of the first support plate 2 and the second support plate 21, the worker puts the fixing nut 24 on the fixing bolt 23 and rotates it, thereby installing the cover 11. The cover 11 can be connected to the sealing ring 25, which can improve the sealing performance. This design makes it easy for workers to install and remove the cover 11, and can improve the sealing performance, thereby effectively preventing the leakage of wastewater and purification agents and reducing safety hazards.

[0027] Furthermore, such as Figure 1 - Figure 4 As shown, the top of the mixing tank 1 is symmetrically provided with positioning grooves 3; a first magnetic block 31 is fixedly connected to the side wall of the positioning groove 3; a second magnetic block 32 is fixedly connected to the bottom of the cover 11; the second magnetic block 32 and the first magnetic block 31 are connected by magnetic connection; during operation, when the operator is installing the cover 11, the second magnetic block 32 can automatically insert into the positioning groove 3 and connect with the first magnetic block 31 by bringing the second magnetic block 32 close to the first magnetic block 31, thereby achieving a quick positioning function. This design enables quick positioning when installing the cover 11, making it easier for the operator to install the cover 11.

[0028] Furthermore, such as Figure 1 - Figure 4As shown, the support block 17 has an installation groove 4 on its side wall; the baffle body 18 has an installation block 41 fixedly connected to its side wall; the installation block 41 and the installation groove 4 are connected by a sliding connection; the top of the support block 17 is symmetrically fixedly connected to a connecting frame 42; the side wall of the connecting frame 42 is fixedly connected to a limiting plate 43; during operation, the baffle body 18 can be disassembled by removing the installation block 41 from the installation groove 4, and the baffle body 18 can be installed by inserting the installation block 41 into the installation groove 4. When installing the baffle body 18, the connecting frame 42 can support the limiting plate 43, which can limit the movement of the installation block 41, thus facilitating the insertion of the installation block 41 into the installation groove 4. This design facilitates the installation and disassembly of the baffle body 18, and also provides a limiting function during installation, making it easier for the installation block 41 to be inserted into the installation groove 4.

[0029] Furthermore, such as Figure 1 - Figure 4 As shown, a handle 5 is fixedly attached to the top of the fixing bolt 23; multiple sets of rubber blocks 51 are fixedly attached to the side wall of the handle 5; during operation, the handle 5 can connect to the rubber blocks 51, and the rubber blocks 51 can increase the friction of the hand. This design can increase the friction of the hand, thereby making it easier for the operator to rotate the handle 5.

[0030] Furthermore, such as Figure 1 - Figure 4 As shown, the bottom end of the support leg 10 is provided with an anti-slip pad 6; the anti-slip pad 6 is connected to the support leg 10 by adhesive bonding; during operation, the anti-slip pad 6 can increase the friction with the ground, and this design can increase the friction with the ground, thereby improving the stability of the equipment during operation.

[0031] Working principle: The mixing tank 1 is supported by the support legs 10, and the mixing tank 1 supports the cover 11. Workers can add wastewater and purifying agent through the feed inlet 101. After addition, the servo motor 13 is supported by the support rod 12. The servo motor 13 rotates, driving the rotating shaft 14 to rotate. The rotating shaft 14 then drives the first stirring rod 15 to rotate. The first stirring rod 15 uses a ribbon-type impeller. During the mixing process, some high-viscosity substances or suspensions may be generated. The ribbon-type impeller is suitable for high-viscosity liquids (200-500 Pa·s) and pseudo-plastic liquids. The fluid, in a laminar flow state, can achieve a combined axial and radial flow, allowing the purifying agent to be fully mixed with wastewater, fly ash, etc., improving the mixing uniformity. Simultaneously, the rotation of the rotating shaft 14 also drives the second stirring rod 16 to rotate. The straight-blade impeller of the second stirring rod 16 primarily generates radial flow, enabling better dispersion of the purifying agent in the radial direction. This facilitates rapid contact with wastewater, fly ash, etc., within a certain range, accelerating the initial mixing process. Furthermore, the support block 17 supports the baffle body 18, which allows for changes in the fluid flow direction during mixing. To increase fluid turbulence, the first support plate 2 and the second support plate 21 provide support. A worker inserts a fixing bolt 23 into the insertion hole 22. After the fixing bolt 23 has completely passed through the surfaces of the first support plate 2 and the second support plate 21, the worker places a fixing nut 24 on the fixing bolt 23 and rotates it, thus installing the cover 11. The cover 11 connects to the sealing ring 25, which improves the sealing performance. When the worker installs the cover 11, the second magnetic block 32 moves close to the first magnetic block 31, and it automatically inserts into the positioning groove 3 to engage with the first magnetic block 31. The connection allows for quick positioning. Workers remove the mounting block 41 from the mounting slot 4, allowing the baffle body 18 to be disassembled. Workers then insert the mounting block 41 into the mounting slot 4, enabling the installation of the baffle body 18. During installation, the connecting bracket 42 supports the limiting plate 43, which acts as a limit, facilitating the insertion of the mounting block 41 into the mounting slot 4. The handle 5 connects to the rubber block 51, increasing hand friction, while the anti-slip pad 6 increases friction with the ground.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
