Abstract
Description
Technical Field
[0001] This utility model relates to the field of calcium fluoride processing technology, specifically to a calcium fluoride metering device. Background Technology
[0002] In chemical, metallurgical, and other industrial production processes, accurate metering of calcium fluoride is crucial for ensuring process stability. Existing calcium fluoride metering devices generally employ a separate design for the storage tank and weighing device. This means that material is extracted from the storage tank via pipelines, screw conveyors, or other transfer mechanisms and then transported to a separately located weighing device for metering. This separate structure reveals the following technical shortcomings in practical applications:
[0003] The separate installation of storage tanks and weighing devices requires separate installation space. Especially in large production lines, the spacing requirements and pipeline routing planning between the two will significantly increase the difficulty of workshop layout. In compact industrial settings, the separate structure may lead to crowded equipment layout due to excessive floor space, or even fail to meet on-site installation conditions. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a calcium fluoride metering device, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a calcium fluoride metering device, comprising a storage tank, a weighing device, and a hinged conveyor;
[0006] The storage tank is mounted on the weighing device, which is used to weigh and record the total weight of the storage tank.
[0007] The hinge conveyor is connected to the bottom of the storage tank, and the weighing device is electrically connected to the hinge conveyor.
[0008] A hopper is provided inside the storage tank, and a crushing assembly is installed inside the hopper to crush the calcium fluoride fed into the storage tank.
[0009] Furthermore, a discharge pipe is connected to the bottom of the hopper.
[0010] Furthermore, the crushing assembly includes at least two support rods installed on the inner wall of the discharge pipe. A bearing is provided at one end of the support rod away from the discharge pipe. A rotating shaft is rotatably sleeved inside the bearing. At least three sets of cutting blades are provided on the outer side of the rotating shaft.
[0011] A support frame is provided on the inner wall of the hopper, and a motor with its output end connected to the rotating shaft is installed on the support frame.
[0012] Furthermore, each set of cutting blades contains three blades.
[0013] Furthermore, at least three sets of the cutting blades are arranged at vertical intervals.
[0014] Furthermore, there are at least three connecting rods on the outer side of the rotating shaft, and a scraper is installed at the end of the connecting rod away from the rotating shaft. The scraper is in contact with the inner wall of the storage tank.
[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0016] 1. This calcium fluoride metering device, by directly mounting the storage tank above the weighing device to form a vertical coaxial structure, eliminates the need for horizontal spacing between the two, reducing the overall footprint of the equipment by approximately 50% compared to traditional designs. This compact layout is particularly suitable for scenarios with limited factory space, allowing for the deployment of more equipment or optimization of other production processes within a confined area.
[0017] 2. This calcium fluoride metering device uses a crushing component with high-speed rotating cutting blades to break up agglomerated calcium fluoride into uniform fine particles upon entering the storage tank. This eliminates material blockage and flow rate fluctuations caused by agglomeration, ensuring that the material enters the metering process in a stable state. This avoids production line interruptions or metering deviations caused by material agglomeration. In conjunction with the synchronous scraping of the scraper, it reduces the interference of material residue and adhesion to the inner wall on the metering weight, enabling the weighing device to more accurately reflect the actual amount of material in the tank and indirectly improving the accuracy of the metering results.

[0022] 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.
[0023] Please see Figure 1-3 The calcium fluoride metering device in this embodiment includes a storage tank 1, a weighing device 2, and a auger conveyor 3. The storage tank 1 is mounted on the weighing device 2, which is used to weigh and record the total weight of the storage tank 1. The auger conveyor 3 is connected to the bottom of the storage tank 1, and the weighing device 2 is electrically connected to the auger conveyor 3.
[0024] In actual use, storage tank 1 contains a certain amount of calcium fluoride material. Weighing device 2 is in standby mode and has completed zero-point calibration to accurately record subsequent weight changes in storage tank 1. The hinged conveyor 3 is in a stopped state, waiting for a start command.
[0025] Calcium fluoride material is added to storage tank 1 by means of pipeline transportation or manual dumping. Since storage tank 1 is set on weighing device 2, weighing device 2 will sense and record the total weight of storage tank 1 and its internal material in real time. This initial weight data provides a basic reference for subsequent measurement work.
[0026] When the calcium fluoride material in storage tank 1 needs to be transported to other places, the operator or control system will issue a transport command. Since the weighing device 2 is electrically connected to the hinged conveyor 3, the weighing device 2 will control the hinged conveyor 3 to start according to the preset transport amount information.
[0027] After the hinge conveyor 3 is started, its spiral blades begin to rotate, pushing the calcium fluoride material at the bottom of the storage tank 1 forward along the spiral channel, thereby realizing the material conveying. In this process, as the material is continuously conveyed out of the storage tank 1, the total weight of the storage tank 1 and the remaining material inside it will gradually decrease.
[0028] Meanwhile, the weighing device 2 will continuously monitor the total weight change of the storage tank 1 in real time and feed the weight data back to the control system. The control system will dynamically adjust the operating status of the hinge conveyor 3 according to the preset conveying target and the real-time monitored weight change.
[0029] If a certain weight of calcium fluoride material needs to be conveyed, when the weighing device 2 detects that the total weight reduction of the storage tank 1 is close to or reaches the preset conveying amount, the control system will promptly issue a deceleration or stop command to the hinged conveyor 3 to ensure that the amount of material conveyed reaches the set value as accurately as possible. This real-time feedback and control mechanism effectively reduces errors in the conveying process and improves the accuracy of measurement.
[0030] When the amount of material conveyed reaches the preset value, the hinge conveyor 3 stops running, and the material conveying process ends. At this time, the weighing device 2 will record the final weight of the storage tank 1 after the conveying is completed. By comparing it with the initial weight, the actual amount of material conveyed can be accurately calculated. If the next conveying task is required, the operator can replenish the material in the storage tank 1 as needed and then repeat the above work process.
[0031] Furthermore, in order to crush the calcium fluoride fed into the storage tank 1 and prevent lumpy calcium fluoride from entering the storage tank 1, a hopper 4 is provided inside the storage tank 1. A crushing component 5 is installed inside the hopper 4 to crush the calcium fluoride fed into the storage tank 1.
[0032] In detail, a discharge pipe 6 is connected to the bottom of the hopper 4. The crushing component 5 includes at least two support rods 501 installed on the inner wall of the discharge pipe 6. A bearing 502 is provided at the end of the support rod 501 away from the discharge pipe 6. A rotating shaft 503 is rotatably sleeved inside the bearing 502. At least three sets of cutting blades 504 are provided on the outer side of the rotating shaft 503. A support frame 505 is provided on the inner wall of the hopper 4. A motor 506 with its output end connected to the rotating shaft 503 is installed on the support frame 505.
[0033] Each set of cutting blades 504 consists of three blades, and at least three sets of cutting blades 504 are arranged vertically at intervals.
[0034] In actual use, the motor 506 starts before or simultaneously with the material entering the hopper 4. The motor 506 is mounted on a support frame 505 on the inner wall of the hopper 4, and its output end is connected to the rotating shaft 503. After the motor 506 is powered on, it drives the connected rotating shaft 503 to rotate. As the shaft 503 rotates, since at least three sets of cutting blades 504 are located on the outer side of the shaft 503, the cutting blades 504 rotate synchronously with the shaft 503. When the agglomerated calcium fluoride material falls into the working range of the cutting blades 504, the high-speed rotating cutting blades 504 cut and crush the agglomerated calcium fluoride.
[0035] Specifically, during the rotation of the cutting blade 504, its sharp edge comes into contact with the agglomerated calcium fluoride, and the agglomerated material is broken into smaller particles through strong shearing force. Since at least three sets of cutting blades 504 are set, the agglomerated material can be cut from different positions and angles, which improves the crushing efficiency and effect and ensures that most of the agglomerated material can be crushed into appropriate sizes.
[0036] Furthermore, the main function of bearing 502 is to support shaft 503, reduce friction when shaft 503 rotates, so that shaft 503 can rotate more smoothly and steadily, ensuring the crushing effect and stability of cutting blade 504, and also extending the service life of shaft 503 and related components.
[0037] Furthermore, in order to prevent calcium fluoride from adhering to the inner wall of the storage tank 1, at least three connecting rods 507 are provided on the outer side of the rotating shaft 503 in this embodiment. A scraper 508 is installed on the end of the connecting rod 507 away from the rotating shaft 503, and the scraper 508 is in contact with the inner wall of the storage tank 1.
[0038] In actual use, when the motor 506 starts, it drives the rotating shaft 503 to rotate. At the same time, the connecting rod 507 installed on the outside of the rotating shaft 503 will also rotate with the rotating shaft 503. Since a scraper 508 is installed on the end of the connecting rod 507 away from the rotating shaft 503, and the scraper 508 is in contact with the inner wall of the storage tank 1, when the rotating shaft 503 rotates, the scraper 508 will make a circular motion along the inner wall of the storage tank 1. When the scraper 508 moves along the inner wall, it will directly contact the calcium fluoride material that has been adhered to the inner wall. Through the scraping action of the scraper 508, the calcium fluoride material adhered to the inner wall is scraped off and returned to the inside of the storage tank 1, thereby keeping the inner wall of the storage tank 1 clean.
[0039] It should be noted that during the crushing and scraping process, the total weight of the storage tank 1 is not recorded to prevent the vibration generated by the motor 506 when driving the rotating shaft 503 to rotate from causing errors in the data obtained by the weighing device 2.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
