Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an experimental device for testing the flocculation effect of flocculants. Background Technology
[0002] Flocculants are widely used in wastewater treatment and water purification, and their flocculation effect directly affects the treatment quality and efficiency. Therefore, accurate testing of flocculant flocculation effect is crucial. However, traditional flocculant flocculation effect testing equipment uses a single paddle stirring structure. This structure makes it difficult to fully mix the flocculant and the liquid to be treated in the reactor. Especially for liquids with high viscosity, flocculant is prone to local accumulation, leading to incomplete flocculation reaction. As a result, the test results cannot truly reflect the performance of the flocculant. In addition, traditional flocculant flocculation effect testing equipment has limited testing functions, usually only able to detect liquid turbidity, lacking monitoring of parameters such as floc particle size, and cannot comprehensively evaluate the flocculation effect of the flocculant. Therefore, we have introduced a new flocculant flocculation effect testing equipment. Utility Model Content
[0003] The main purpose of this invention is to provide an experimental device for testing the flocculation effect of flocculants, which can effectively solve the problems in the background technology.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] An experimental device for testing the flocculation effect of a flocculant includes a reaction vessel. A square frame is fixedly connected to the upper rear of the reaction vessel, and a connecting plate is fixedly connected to the upper front of the square frame. A multi-stage mixing reaction group is installed inside the square frame. Detection components are installed on the left and right sides of the outer surface of the reaction vessel. Three fixing blocks are fixedly connected to the upper part of the outer surface of the reaction vessel, and each of the three fixing blocks has a through-hole at its upper end. A liquid input pipe is fixedly connected to the upper left of the reaction vessel, and a flocculant input pipe is fixedly connected to the upper right of the reaction vessel. A drain pipe is fixedly connected to the lower end of the reaction vessel. Electric valves are movably installed on the outer surfaces of the liquid input pipe, the flocculant input pipe, and the drain pipe. A control panel is provided on the front of the outer surface of the reaction vessel.
[0006] Preferably, the detection component includes a U-shaped plate, with a first through-hole at the upper left end of the left U-shaped plate and a second through-hole at the lower left end of the left U-shaped plate. A turbidity sensor is fixedly fitted into the first mounting hole, and a particle size analyzer is fixedly fitted into the second mounting hole. The right end of the left U-shaped plate is fixedly connected to the outer surface of the reaction vessel.
[0007] By adopting the above technical solution: the turbidity sensor model is E+H Turbimax CUS51D, which meets the requirements of the flocculant flocculation effect testing equipment for monitoring the turbidity of the liquid in the reactor; the particle size analyzer model is Anton Paar Litesizer DIF 500, which can determine the particle size distribution of flocculants in the reactor during flocculant flocculation effect testing, providing key data support for evaluating the flocculation effect.
[0008] Preferably, the detection head of the turbidity sensor and the detection head of the particle size analyzer both penetrate the outer surface of the reactor and extend into the reactor. The turbidity sensor and the particle size analyzer are both electrically connected to the control panel via connecting cables.
[0009] By adopting the above technical solution, the turbidity sensor and particle size analyzer are electrically connected to the control panel via a connecting cable, enabling the detection data to be transmitted to the control panel quickly and accurately. The microprocessor in the control panel can analyze and process the collected data according to preset algorithms and programs.
[0010] Preferably, the multi-stage mixing reaction assembly includes a motor base, on the upper end of which a variable frequency motor is fixedly mounted. A main bevel gear is fixedly mounted on the output end of the variable frequency motor. A first mixing reaction mechanism is meshed with the lower part of the outer surface of the main bevel gear, and a second mixing reaction mechanism is meshed with the upper part of the outer surface of the main bevel gear. The lower end of the motor base is fixedly connected to the lower inner wall of the square frame. The rear end of the variable frequency motor is fixedly connected to the rear inner wall of the square frame. The front end of the variable frequency motor is fixedly connected to the front inner wall of the square frame, and the output end of the variable frequency motor passes through the front inner wall of the square frame and extends to the outside of the square frame.
[0011] By adopting the above technical solution: the multi-stage mixing reaction group drives the main bevel gear to rotate through the frequency conversion motor, thereby driving the first mixing reaction mechanism and the second mixing reaction mechanism to work simultaneously. This design can form stirring forces of different levels and directions in the reactor, so that the liquid to be treated and the flocculant are fully mixed in multiple dimensions.
[0012] Preferably, the first mixing reaction mechanism includes a first auxiliary bevel gear, a first rotating rod is fixedly connected to the lower end of the first auxiliary bevel gear, a first fixing ring is fixedly sleeved on the upper and lower parts of the outer surface of the first rotating rod, a plurality of helical blades are fixedly connected to the outer surfaces of the two first fixing rings, a plurality of first flat blades are fixedly connected to the middle part of the outer surface of the first rotating rod, and the outer surface of the first auxiliary bevel gear and the outer surface of the main bevel gear are meshed.
[0013] By adopting the above technical solution: when the spiral blades rotate, they can generate axial and radial liquid flow, so that the liquid circulates up and down in the reactor, promoting the mixing of flocculant and liquid to be treated in the vertical direction. The first flat blade generates strong shear force by rotating, which quickly disperses the liquid in the horizontal direction.
[0014] Preferably, the lower end of the first rotating rod is movably connected to the upper end of the reactor through a bearing, and a plurality of the spiral blades are arranged in a circular array around the center of the first rotating rod, and a plurality of the first flat blades are arranged in pairs at equal distances and are all inclined.
[0015] By adopting the above technical solution, several helical blades are arranged in a ring array around the center of the first rotating rod. When rotating, they can push the liquid from multiple directions to form a uniform and powerful axial and radial liquid flow, which promotes the all-round circulation of the liquid in the reactor.
[0016] Preferably, the second mixing reaction mechanism includes a second auxiliary bevel gear, a second rotating rod is fixedly connected to the lower end of the second auxiliary bevel gear, a second fixing ring is fixedly sleeved on the lower part of the outer surface of the second rotating rod, a plurality of anchor blades are fixedly connected to the outer surface of the second fixing ring, a plurality of second flat blades are fixedly connected to the ends of the plurality of anchor blades near the second rotating rod, and the ends of the plurality of second flat blades near the second rotating rod are fixedly connected to the outer surface of the second rotating rod, and the outer surface of the second auxiliary bevel gear meshes with the outer surface of the main bevel gear.
[0017] By adopting the above technical solution: the anchor blades rotate to push the liquid, allowing the liquid to be treated at the bottom of the reactor to come into full contact with the flocculant, accelerating the flocculation reaction in the bottom area. At the same time, the second flat blades are fixed between the anchor blades and the second rotating rod, generating additional shear force and stirring force during rotation, further enhancing the degree of liquid mixing, ensuring that the liquid at the bottom of the reactor is mixed evenly, avoiding the impact of insufficient mixing at the bottom on the overall flocculation effect, and improving the accuracy and reliability of the test results.
[0018] Preferably, the upper end of the second bevel gear is movably connected to the lower end of the connecting plate via a rotating shaft, and the upper part of the second rotating rod is movably sleeved inside the first bevel gear and the first rotating rod.
[0019] By adopting the above technical solution: the upper part of the second rotating rod is movably sleeved in the first bevel gear and the first rotating rod. At the same time, the first mixing reaction mechanism and the second mixing reaction mechanism rotate in different directions through the rotation of the main bevel gear, generating complex and intersecting liquid flows in the reactor. The two liquid flows in different directions impact and collide with each other, forming a strong turbulent effect. This turbulence can break the laminar flow state of the liquid, allowing the flocculant and the liquid to be treated to fully mix in various areas of the reactor, greatly improving the mixing uniformity, avoiding the situation of insufficient local mixing, creating more favorable conditions for the flocculation reaction, and making the test results more accurately reflect the actual effect of the flocculant.
[0020] Preferably, the shape and size of the lower part of several of the anchor blades are adapted to the conical structure at the bottom of the reactor.
[0021] By adopting the above technical solution: the conical structure at the bottom of the reactor can easily cause the sedimentation of liquids or impurities with high density, which affects the flocculation reaction and the detection results. The matching anchor blades continuously stir the liquid at the bottom of the reactor during rotation, and the generated liquid flow can effectively prevent the sedimentation of liquid and impurities, keep the liquid in suspension, and allow the flocculant to fully react with the impurities in the liquid to be treated.
[0022] Compared with the prior art, the present invention has the following beneficial effects:
[0023] 1. In this utility model, efficient mixing is achieved through a multi-stage mixing reaction group. During operation, the variable frequency motor drives the main bevel gear to rotate, which in turn drives the first and second auxiliary bevel gears, causing the first and second mixing reaction mechanisms to operate. The spiral blades and the first flat blades on the first rotating rod stir the liquid in the upper part of the reactor, while the anchor blades and the second flat blades on the second rotating rod stir the liquid in the lower part. The anchor blades are adapted to the conical structure at the bottom of the reactor. This multi-stage mixing method allows the flocculant and the liquid to be treated to come into rapid and full contact in the reactor, accelerating the flocculation reaction. Compared with traditional single stirring equipment, the reaction time is greatly shortened, effectively improving the detection efficiency.
[0024] 2. In this invention, the turbidity sensor and particle size analyzer in the detection component monitor the liquid parameters in the reactor in real time. The turbidity sensor detects changes in liquid turbidity, and the particle size analyzer analyzes the particle size distribution of flocculants. Both transmit analog signals to the data acquisition module of the control panel. After processing, the microprocessor calculates the parameters of flocculation time, particle size distribution, and turbidity change curve. Compared with traditional devices that only detect turbidity, this device can obtain more comprehensive data, evaluate the flocculation effect of flocculants, and greatly reduce the error rate, providing a reliable basis for flocculant performance research and optimization.
