Description

Technical Field

[0001] This utility model relates to the field of flocculant processing technology, specifically to a jet-type flocculant mixing device. Background Technology

[0002] Flocculants are substances that can cause fine suspended particles in a liquid to aggregate into larger flocs. They are widely used in water treatment, papermaking, food processing and many other fields. When flocculants dissolve in water, the ions they produce interact with the charges on the surface of colloidal particles in the water, compressing the double layer around the colloidal particles and reducing its thickness. This reduces the electrostatic repulsion between particles, making them easier to approach and aggregate. The charged ions of the flocculant attract the opposite charges on the surface of the colloidal particles, neutralizing the charge on the particle surface, reducing the particle potential and stability, and thus causing aggregation.

[0003] The existing patent announcement number CN212417657U discloses a jet-type flocculant mixer, comprising a mixer base, a stepper motor, a first rotating shaft, a support seat, and an annular limiting groove. The top of the mixer base is provided with a support seat, and the bottom end of the support seat is fixedly connected to the mixer base. A mixing cylinder is provided on the top of the mixer base on one side of the support seat. A transmission rod is provided inside the mixing cylinder, with one end extending into the interior of the support seat. A stirring blade is provided on the surface of the transmission rod below the support seat. The inner wall of the stirring blade is fixedly connected to the transmission rod. A limiting mechanism is provided on the outer wall of the support seat on one side of the mixing cylinder, and a conveying box is provided at the bottom of the mixer base below the limiting mechanism. This invention not only achieves efficient and rapid mixing of jet-type flocculants, preventing viscous flocculants from clogging the mixer outlet, but also improves the working efficiency of the mixer.

[0004] Existing jet-type flocculant mixing devices have the following problems: when mixing flocculants, using a single jet nozzle to mix the flocculants cannot thoroughly mix them, resulting in poor mixing effect. Therefore, we propose a jet-type flocculant mixing device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a jet-type flocculant mixing device. When mixing the flocculant, the flocculant is mixed twice to ensure thorough mixing and better mixing effect, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a jet-type flocculant mixing device, comprising a mixing tank, a connecting pipe at the feed inlet at the upper end of the mixing tank, a diffuser at the left end of the connecting pipe, a mixing pipe at the left end of the diffuser, a nozzle inside the left end of the mixing pipe, and a suction chamber inside the left end of the mixing pipe, and also includes a secondary mixing mechanism.

[0007] The secondary mixing mechanism includes a protective cover, a rotating shaft, a rotating cylinder, support blocks, and stirring blades. The upper end of the mixing tank is equipped with a protective cover, and the top wall of the protective cover is rotatably connected to the rotating shaft. The sliding groove on the inner wall of the rotating cylinder is slidably connected to the sliding strip on the outer wall of the rotating shaft. The outer wall of the rotating cylinder is fixedly connected with evenly distributed support blocks, and the outer ends of the support blocks are respectively fixedly connected with stirring blades. When mixing the flocculant, the flocculant is mixed twice to ensure thorough mixing and better mixing effect.

[0008] Furthermore, a control switch group is provided on the outside of the mixing tank. The input end of the control switch group is electrically connected to an external power source to provide electrical connections for each electrical appliance.

[0009] Furthermore, the secondary mixing mechanism also includes a drive assembly, which includes a spring, a retaining ring, a support rod, a roller, and a wave-shaped boss. The upper edge of the rotating cylinder is provided with a support rod, and the front end of the support rod is rotatably connected to a roller. The lower side of the inner wall of the protective cover is provided with a wave-shaped boss. The outer wall of the roller and the upper surface of the wave-shaped boss are slidably connected. The upper end of the rotating cylinder is fixedly connected with a retaining ring. A spring is sleeved on the outside of the rotation shaft between the upper end of the retaining ring and the top wall of the protective cover to realize up-and-down swinging.

[0010] Furthermore, the drive assembly also includes a motor, which is disposed at the upper end of the protective cover. The lower end of the motor's output shaft is fixedly connected to the upper end of the rotating shaft, and the input end of the motor is electrically connected to the output end of the control switch group to provide rotation drive.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This jet-type flocculant mixing device has the following advantages:

[0015] Driven by a motor, the rotating shaft, rotating cylinder, and support block drive the stirring blades to perform secondary mixing of the flocculant inside the mixing tank. The rotating cylinder drives the rollers and corrugated protrusions via the support rod. When the rollers contact the highest point of the corrugated protrusions, the support rod drives the stirring blades upward through the rotating cylinder. When the rollers contact the lowest point of the corrugated protrusions, the rotating cylinder moves downward under the rebound action of the spring and the retaining ring. This causes the stirring blades to rotate and swing up and down, thus thoroughly mixing the flocculant inside the mixing tank. By mixing the flocculant twice, the flocculant is thoroughly mixed, resulting in a better mixing effect. Attached Figure Description

Detailed Implementation

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a jet-type flocculant mixing device, including a mixing tank 1, a connecting pipe 3 at the feed inlet at the upper end of the mixing tank 1, a diffuser 4 at the left end of the connecting pipe 3, a mixing pipe 5 at the left end of the diffuser 4, a nozzle 7 inside the left end of the mixing pipe 5, and a suction chamber 6 inside the left end of the mixing pipe 5. It also includes a secondary mixing mechanism 9. A control switch group 12 is provided outside the mixing tank 1, with its input terminal electrically connected to an external power source. A support 2 is provided on the outer wall of the mixing tank 1, with a high-pressure pump 13 at the upper end of the support 2. The output port of the high-pressure pump 13 is connected to the feed inlet at the left end of the nozzle 7. A feed pipe 8 is provided at the upper end of the mixing pipe 5, with its lower end connected to the suction chamber 6. The input terminal of the high-pressure pump 13 is electrically connected to the control switch group 9. The output end of the control switch group 12 is provided with a discharge pipe 11 at the discharge port at the lower end of the mixing tank 1. A valve is connected in series with the outside of the discharge pipe 11. The lower end of the outer wall of the mixing tank 1 is provided with evenly distributed support legs 10. When the flocculant is mixed, it is then connected to the input port of the high pressure pump 13 through the external material pipe. The water pipe will enter the suction chamber 6 through the feed pipe 8. Then, by controlling the control switch group 12, the high pressure pump 13 will operate. The high pressure pump 13 will accelerate the flocculant into a high-speed jet through the nozzle 7 and enter the mixing pipe 5. In the suction chamber 6, the high-speed jet collides violently with the water, forming turbulence, which promotes the uniform dispersion of flocculant. The mixed fluid passes through the throat pipe for further uniform mixing. The fluid enters the diffuser pipe 4, where the flow rate decreases and the mixing effect is stable.

[0023] The secondary mixing mechanism 9 includes a protective cover 92, a rotating shaft 93, a rotating cylinder 94, support blocks 95, and stirring blades 96. The upper end of the mixing tank 1 is provided with a protective cover 92. The top wall of the protective cover 92 is rotatably connected to the rotating shaft 93. The sliding groove on the inner wall of the rotating cylinder 94 is slidably connected to the sliding strip on the outer wall of the rotating shaft 93. Evenly distributed support blocks 95 are fixedly connected to the outer wall of the rotating cylinder 94. Stirring blades 96 are fixedly connected to the outer ends of the support blocks 95 respectively. The secondary mixing mechanism 9 also includes a drive assembly 91, which includes a spring 912, a retaining ring 913, and a support rod 914. The rotating cylinder 94 has a support rod 914 at its upper edge, with the front end of the support rod 914 rotatably connected to the roller 915. A wave-shaped boss 916 is provided on the lower inner wall of the protective cover 92. The outer wall of the roller 915 and the upper surface of the wave-shaped boss 916 are slidably connected. A retaining ring 913 is fixedly connected to the upper end of the rotating cylinder 94. A spring 912 is sleeved on the outside of the rotating shaft 93 between the upper end of the retaining ring 913 and the top wall of the protective cover 92. The drive assembly 91 also includes a motor 911, which is located at the upper end of the protective cover 92. The lower end of the output shaft of motor 911 is fixedly connected to the upper end of the rotating shaft 93. The input end of motor 911 is electrically connected to the output end of control switch group 12. Then, the mixed flocculant enters the mixing tank 1. Next, by adjusting the control switch group 12, motor 911 operates. The output shaft of motor 911 drives the rotating shaft 93 to rotate. The rotation of rotating shaft 93 drives the rotating drum 94 to rotate through the slide groove and slide bar. The rotation of rotating drum 94 drives the stirring plate 96 to rotate through the support block 95. The rotation of stirring plate 96 will perform secondary mixing of the flocculant inside the mixing tank 1. During rotation, the rotating cylinder 94 will drive the support rod 914 to rotate, and the support rod 914 will drive the roller 915 to contact the corrugated boss 916. When the outer surface of the roller 915 contacts the highest point of the corrugated boss 916, the rotating cylinder 94 will be driven to move upward through the support rod 914, which will in turn drive the stirring plate 96 to move upward. Then, when the outer surface of the roller 915 contacts the lowest point of the corrugated boss 916, the rotating cylinder 94 will swing up and down outside the rotating shaft 93 under the rebound action of the spring 912 and the retaining ring 913, thereby thoroughly mixing the flocculant inside the mixing tank 1.

[0024] The working principle of the jet-type flocculant mixing device provided by this utility model is as follows: When mixing the flocculant, the external feed pipe is connected to the input port of the high-pressure pump 13, and the water pipe enters the suction chamber 6 through the feed pipe 8. Then, by controlling the control switch group 12, the high-pressure pump 13 is activated. The high-pressure pump 13 accelerates the flocculant into a high-speed jet through the nozzle 7 and enters the mixing pipe 5. In the suction chamber 6, the high-speed jet collides violently with the water, forming turbulence, which promotes the uniform dispersion of the flocculant. The mixed fluid passes through the throat pipe for further uniform mixing. The fluid enters the diffuser pipe 4, where the flow rate decreases and the mixing effect stabilizes. Then, the mixed flocculant enters the mixing tank 1. Then, by controlling the control switch group 12, the motor 911 is activated. The output shaft of the motor 911 drives the rotating shaft 93 to rotate. The rotation of the rotating shaft 93 will drive the rotating cylinder 94 to rotate via the sliding groove and the sliding bar. The rotation of the rotating cylinder 94 will drive the stirring plate 96 to rotate via the support block 95. The rotation of the stirring plate 96 will perform secondary mixing of the flocculant inside the mixing tank 1. When the rotating cylinder 94 rotates, it will drive the support rod 914 to rotate. The support rod 914 will drive the roller 915 to contact the corrugated boss 916. When the outer surface of the roller 915 contacts the highest point of the corrugated boss 916, it will drive the rotating cylinder 94 to move upward via the support rod 914, which will in turn drive the stirring plate 96 to move upward. Then, when the outer surface of the roller 915 contacts the lowest point of the corrugated boss 916, the rotating cylinder 94 will swing up and down outside the rotating shaft 93 under the rebound action of the spring 912 and the retaining ring 913, thereby thoroughly mixing the flocculant inside the mixing tank 1.

[0025] It is worth noting that the motor 911 and high-pressure pump 13 disclosed in the above embodiments can be selected as 5Ik12RGU-CF for motor 911 and IDB70 for high-pressure pump 13. The control switch group 12 is provided with switch buttons that correspond one-to-one with motor 911 and high-pressure pump 13 and are used to control their switching operation.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
