Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of chemical raw material mixing, specifically a chemical raw material mixing tank. Background Technology
[0002] Mixing tank stirring is one of the most common operations in the chemical, petrochemical, pharmaceutical, and food industries. Its purpose is to enable two or more media to reach maximum contact, thereby completing the required mixing, mass transfer, heat transfer, or reaction process within a predetermined time. In the process of chemical product production, it is generally necessary to mix and stir chemical raw materials through mixing tanks.
[0003] Traditional mixing tanks typically use simple inlet valves or manual pouring for feeding, often involving dumping large quantities of raw materials at once. This single-pour method can lead to excessively high local concentrations within the tank, increasing the instantaneous load on the agitator and making it difficult to disperse the material quickly. Furthermore, simple continuous feeding lacks effective "cutting" and "quantitative" mechanisms, causing raw materials to agglomerate or distribute unevenly from the initial stage of entering the mixing tank. This results in longer mixing times and higher energy consumption. While some existing equipment features quantitative feeding structures, the rotating drum in these structures is usually fixed inside the feed hopper, meaning the amount fed each time is constant. This slows down the mixing speed for easily soluble solids, and over time, solid materials inevitably adhere to the feed hopper, making cleaning difficult and affecting the mixing of subsequent raw materials. Utility Model Content
[0004] To solve the above problems, namely the problems raised in the background art, this utility model proposes a chemical raw material mixing tank, which includes a mixing tank body. The mixing tank body includes a cover, a tank body, a mixing component, and a discharge component. An inlet pipe and a quantitative dispensing structure are installed on the upper side of the cover. The quantitative dispensing structure includes a symmetrical dispensing component and a driving component.
[0005] Each of the aforementioned feeding components includes a material cylinder, a feeding pipe, a feeding pipe, a movable sealing door, a turntable, a set of trapezoidal slide bars, and a rotating cylinder;
[0006] The upper and lower ends of the material cylinder are respectively fixedly connected to the feed pipe and the discharge pipe. The discharge pipe is fixedly connected to the cover. One end of the material cylinder is movably connected to the movable sealing door. The central shaft of the turntable is connected to and passes through one end of the material cylinder. A set of evenly arranged trapezoidal slide rods is fixedly connected to the other side of the turntable. The outer side of the set of trapezoidal slide rods is in contact with the inner wall of the material cylinder. A set of evenly arranged trapezoidal grooves and receiving grooves are provided on the outer side of the turntable. The set of trapezoidal grooves and the set of receiving grooves are staggered. The set of trapezoidal grooves matches the corresponding trapezoidal slide rods. The outer side of the turntable is in contact with the inner wall of the material cylinder.
[0007] A further feature of this invention is that the drive assembly includes a motor, a driving wheel, and a pair of driven wheels;
[0008] The cover has an upright plate on its upper side. The motor is fixedly connected to the upright plate. The output end of the motor passes through the upright plate and is fixedly connected to the driving wheel. The driving wheel is an incomplete gear with 1 / 4 tooth. The central shaft of a pair of turntables is fixedly connected to the corresponding driven wheel. Each driven wheel is an incomplete gear with teeth and concave locking arcs distributed alternately. The concave locking arc of each driven wheel matches the convex locking arc of the driving wheel.
[0009] A further feature of this invention is that the mixing assembly includes a second motor, a rotating shaft, a set of stirring rods, and a pair of scrapers.
[0010] The second motor is mounted on the upper side of the cover. The output end of the second motor passes through the cover and is fixedly connected to the rotating shaft. A set of evenly arranged stirring rods are fixedly connected to the outside of the rotating shaft. A pair of scrapers are fixedly connected to the bottom of the rotating shaft. The outer sides of the pair of scrapers are attached to the bottom and side wall of the mixing tank. During the stirring process, the pair of scrapers effectively scrape off the raw materials adhering to the tank wall, prevent material accumulation in dead corners, and further ensure the uniformity of mixing.
[0011] A further feature of this invention is that both the inner and outer rings of the pair of movable sealing doors are covered with sealing strips.
[0012] A further feature of this invention is that a set of evenly arranged top beads are rolled inside the pair of movable sealing doors, which, while pressing the rotating cylinder against the turntable, makes the rotating cylinder rotate more smoothly.
[0013] A further feature of this invention is that the cross-sections of the lower opening of each feed pipe, the upper opening of the receiving trough, and the upper opening of the discharge pipe are the same, ensuring that the amount of material received each time is consistent. If the receiving troughs are of different volumes, the area of the upper opening is different, only the depth is different.
[0014] A further feature of this invention is that a circular groove is provided along the central axis of the rotating drum to reduce its weight. A handle is fixedly connected to one end of the circular groove to facilitate the installation and disassembly of the rotating drum, as well as the replacement of rotating drums of different volumes and the cleaning of the rotating drum, thus ensuring the purity and quality of raw materials when mixing different batches.
[0015] A further feature of this invention is that the discharge assembly includes a discharge pipe and a valve.
[0016] A further feature of this invention is that the movable sealing door can be fixed to the material cylinder by a buckle or by magnetic attraction.
[0017] A further feature of this invention is that the first motor is a medium-low speed motor.
[0018] The beneficial technical effects of this utility model are as follows: This utility model achieves a "receiving-rotating-discharging" cycle mechanism for solid raw materials through a symmetrically arranged quantitative feeding structure, replacing the problems of raw material agglomeration and difficulty in dispersion caused by traditional manual pouring or one-time feeding. Intermittent quantitative feeding allows raw materials to enter the tank in batches and evenly, avoiding excessively high local concentrations in the tank and reducing the instantaneous load on the stirring device. Combined with the efficient stirring of the mixing component, it achieves the purpose of "mixing while feeding". In the mixing component, the scraper at the bottom of the rotating shaft can adhere to the inner wall and bottom of the tank to scrape off the adhering raw materials, avoid local accumulation, and ensure full contact of the raw materials. This application reduces the probability of raw material agglomeration by batch quantitative feeding, and achieves uniform mixing without long-term high-intensity stirring, significantly reducing equipment energy consumption and mixing time costs. It is especially suitable for mixing various chemical raw materials. Moreover, the rotating drum is a detachable drum, and different volumes of receiving tanks can be selected according to the reaction of the solid and liquid raw materials to facilitate mixing of different solid raw materials and easy cleaning.

[0024] The following is a reference to the appendix. Figures 1-4 The preferred embodiments of this utility model are described below. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.
[0025] This utility model proposes a chemical raw material mixing tank. When using this device, a rotating drum 10 with a suitable volume for the receiving trough 3 is selected according to process requirements. The handle is used to align a set of trapezoidal grooves on the rotating drum 10 with the corresponding trapezoidal slide rod 2. Pushing the handle causes the rotating drum 10 to slide onto the corresponding trapezoidal slide rod 2 via the trapezoidal grooves. After one end of the rotating drum 10 is pressed against one side of the turntable 15, the movable sealing door 4 is closed. A set of top beads 14 on the movable sealing door 4 pushes the rotating drum 10 to fit tightly against the turntable 15. At this time, the lower opening of the feed pipe 1 and the discharge pipe 7 are connected to the corresponding receiving trough 3. Solid raw materials are conveyed into the feed pipe 1 through an auger or other feeding structure. The solid raw materials in the feed pipe 1 slide into the corresponding receiving trough 3 due to their own gravity. An external liquid pump is connected to the inlet pipe to pump the liquid raw material into the tank. Motor 13 and Motor 2 16 are started. Motor 13 drives the drive wheel 12 to rotate. The convex locking arc of the drive wheel 12 slides along the concave locking arc of the corresponding driven wheel 11. When the teeth of the drive wheel 12 mesh with the teeth of a driven wheel 11, the drive wheel 12 drives the driven wheel 11 to rotate. The driven wheel 11 drives the corresponding rotating drum 10 to rotate along the inner wall of the material cylinder 9 via the corresponding turntable 15. When the teeth of the drive wheel 12 disengage from a driven wheel 11, the convex locking arc of the drive wheel 12 engages with the concave locking arc of the driven wheel 11. At this time, the driven wheel 11 drives the corresponding rotating drum 10 to rotate 90°. When the drive wheel 12 rotates 180°, the drive wheel 12... The gear teeth mesh with the gear teeth of another driven wheel 11, driving the other driven wheel 11 and the corresponding rotating drum 10 to rotate 90°. The operation process is the same and will not be described again. The solid raw materials in the two drums 9 are quantitatively and alternately fed, replacing the problem of raw material agglomeration and difficulty in dispersion caused by traditional manual pouring or one-time feeding. Intermittent quantitative feeding allows the raw materials to enter the tank in batches and evenly, avoiding excessively high local concentrations in the tank and reducing the instantaneous load on the stirring device. At the same time, the motor 16 drives the rotating shaft to rotate, and the rotating shaft drives a set of stirring rods 18 to rotate to mix and stir the solid and liquid raw materials in the tank. The rotating shaft drives a pair of scrapers 19 to slide along the inner wall of the tank, scraping off the raw materials adhering to the inner wall of the tank and adding them to the mixing, avoiding local accumulation and ensuring that the raw materials are fully mixed. The process involves partial contact to achieve "simultaneous feeding and mixing." Once the mixture is uniform, motor 16 is turned off (during the mixing process, the external liquid pump automatically shuts off after a certain amount of liquid raw material is pumped in; motor 13 is turned off after all the solid raw material has fallen into the tank, leaving only motor 16 running). The discharge assembly is then opened to collect the mixed raw material. This application's batch-quantitative feeding reduces the probability of raw material agglomeration and achieves uniform mixing without prolonged high-intensity stirring, significantly reducing equipment energy consumption and mixing time costs. It is particularly suitable for mixing various chemical raw materials. Furthermore, the rotating drum 10 is a detachable drum, allowing for the selection of receiving tanks 3 with different volumes based on the reaction of the solid and liquid raw materials being mixed. This facilitates the mixing of different solid raw materials and makes cleaning easier.
