Technical Field
[0001] This utility model relates to the technical field of chemical raw material mixing equipment, specifically a raw material mixing device for preparing scale inhibitors and dispersants. Background Technology
[0002] The preparation of scale inhibitors and dispersants involves processing core raw materials such as organophosphonic acids, polycarboxylic acids, and polymers containing sulfonic acid groups, along with auxiliary agents such as corrosion inhibitors and surfactants, through processes such as solution polymerization, compounding, and melt reaction. In the preparation of scale inhibitors and dispersants, it is necessary to fully mix various raw materials of different forms (solid and liquid) and different properties to ensure the quality and performance of the scale inhibitors and dispersants.
[0003] However, existing mixing devices still have certain problems in use:
[0004] For example, application number CN202021147330.0 describes a mixing tank for preparing a high-efficiency scale inhibitor and dispersant, which includes a mixing tank, an inlet pipe at the upper end and an outlet pipe at the lower end of the mixing tank, a drive motor installed at the upper end of the mixing tank, a rotating rod fixedly connected to the output end of the drive motor, the rotating rod passing through the mixing tank and rotatably connected thereto, a plurality of connecting pipes fixedly connected to the rotating rod, each of the plurality of connecting pipes having a notch, a plurality of through holes passing through the end of the plurality of connecting pipes opposite to the rotating rod, an annular block fixedly mounted on the rotating rod below the connecting pipe, a plurality of inclined plates fixedly connected to the annular block, and two vertical mesh plates fixedly connected to the inner wall of the mixing tank;
[0005] Traditional mixing devices have a relatively simple stirring structure, which can lead to uneven stirring during the preparation of scale inhibitors and dispersants. This results in poor mixing of raw materials and affects the preparation effect of scale inhibitors and dispersants. In addition, the mixing devices lack an effective heating system, making it difficult to guarantee process conditions in scenarios where heating is required to promote dissolution or reaction.
[0006] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.
[0007] To address the aforementioned issues, an innovative design was implemented based on the existing raw material mixing device. Utility Model Content
[0008] The purpose of this invention is to provide a raw material mixing device for preparing scale inhibitors and dispersants, in order to solve the problems mentioned in the background art, which have a simple stirring structure, resulting in uneven stirring during the preparation of scale inhibitors and dispersants, leading to poor raw material mixing effect and affecting the preparation effect of scale inhibitors and dispersants. Moreover, the mixing device lacks an effective heating system, making it difficult to guarantee process conditions in scenarios where heating is required to promote dissolution or reaction.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A raw material mixing device for preparing a scale inhibitor and dispersant includes a main container and a top cover. The top cover is connected to the upper flange of the main container. A motor is installed on the top cover. A frequency converter is installed at the output end of the motor. A stirring shaft is connected to the middle of the frequency converter. A mounting sleeve is bolted to the outer surface of the stirring shaft. A transverse stirring rod is fixed to the outer surface of the mounting sleeve. A longitudinal stirring rod is fixed to the top end of the transverse stirring rod. Stirring blades are fixed to the outer surface of the stirring shaft. A heating jacket is welded to the outer surface of the main container. A steam inlet is connected to one side of the heating jacket, and a steam outlet is connected to the other side of the heating jacket. A guide plate is provided inside the heating jacket.
[0011] By adopting the above technical solution, the stirring shaft is driven by a motor, and the stirring rods and blades move at multiple angles to achieve full mixing of the raw materials. At the same time, steam enters the heating jacket through the air inlet and forms a spiral flow path under the action of the guide plate, which evenly heats the materials in the main container, promotes dissolution and reaction, achieves efficient mixing effect, and ensures the processing technology.
[0012] Preferably, four sets of mounting sleeves are arranged along the outer surface of the stirring shaft, and the transverse stirring rods and longitudinal stirring rods are symmetrically designed along the mounting sleeves.
[0013] By adopting the above technical solution, four sets of installation sleeves are evenly distributed along the stirring shaft, and the symmetrical layout of the horizontal and vertical stirring rods is combined to form a multi-dimensional and fully covered stirring area when the stirring shaft rotates. This allows the material to be subjected to shearing and convection in both the horizontal and vertical directions, which significantly improves the mixing efficiency and uniformity.
[0014] Preferably, the stirring blades are arranged in three sets along the outer surface of the stirring shaft, and the length of the stirring blades decreases from top to bottom.
[0015] The above technical solution, with the design of three sets of stirring blades decreasing in length from top to bottom along the stirring shaft, creates differentiated stirring intensities at different heights when the stirring shaft rotates. The upper layer of long blades expands the stirring range, the middle layer of blades enhances shear force, and the lower layer of short blades stays close to the bottom of the container to prevent sedimentation. This achieves layered stirring in the vertical direction, ensuring that the materials in the upper, middle, and lower regions are fully mixed.
[0016] Preferably, the guide plate has a spiral structure and is circumferentially attached to the outer surface of the main container. A partition is fixed in the middle of the guide plate, and guide grooves are formed between the guide plates.
[0017] By adopting the above technical solution, the spiral guide plate is attached to the outer surface of the main container in a ring shape, so that the steam flows along the spiral path in the guide groove, which prolongs the heat exchange time. The middle baffle further divides the flow channel, which promotes the uniform distribution of steam around the container, thereby achieving uniform heating of the material in the main container, reducing the temperature gradient, and improving the temperature control accuracy and heating efficiency.
[0018] Preferably, the outer surface of the main container is welded with support legs, and the support legs are arranged in three sets in a ring.
[0019] By adopting the above technical solution, three sets of ring-shaped support legs are welded to the outer surface of the main container, which can enhance the stability of the device, avoid swaying or tilting caused by the shift of the center of gravity, and improve the stability of the device during operation.
[0020] Preferably, the outer surface of the top cover is connected to a solid feed inlet, the outer surface of the top cover is connected to a liquid feed inlet, the bottom of the main container is connected to a discharge outlet, and a valve is installed in the middle of the discharge outlet.
[0021] The above technical solution is adopted. The top cover is equipped with a solid feed port and a liquid feed port, which can realize the quantitative feeding of solid raw materials and the pipeline transportation of liquid raw materials respectively, avoiding mutual interference when raw materials of different forms are mixed. The discharge port at the bottom of the main container is equipped with a valve to ensure convenient unloading.
[0022] Preferably, a support frame is fixed to the bottom of the main container, and the bottom end of the stirring shaft is rotatably connected to the support frame.
[0023] By adopting the above technical solution, the support frame at the bottom of the main container is rotatably connected to the bottom of the stirring shaft, so as to provide a stable support point for the rotation of the stirring shaft, reduce shaking and improve stability during the stirring process.

Combined with three sets of stirring blades with decreasing lengths, it realizes differentiated shearing and convection of materials at different heights, enhances the mixing effect of raw materials, and achieves thorough mixing of raw materials.
[0026] 2. The heating jacket welded to the outer surface of the main container introduces steam through the steam inlet. The steam flows in a spiral ring along the main container within the guide channel formed by the spiral guide plate and the baffle, which prolongs the contact path and time between the steam and the main container, enhances the heat exchange efficiency, promotes dissolution and reaction, achieves efficient mixing effect, and ensures the processing technology.
