Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of high-temperature resistant material processing technology, and more specifically, to a quantitative packaging device for high-temperature resistant castables. Background Technology

[0002] In high-temperature industrial fields, such as steel smelting, glass manufacturing, and cement production, high-temperature castables, as key unshaped refractory materials, are widely used in constructing high-temperature furnace linings and repairing thermal equipment due to their good plasticity and high fluidity, which can be formed by casting.

[0003] In the past, traditional methods for packaging high-temperature resistant castables had many drawbacks. Early packaging was done manually, with workers scooping the castable from storage containers and pouring it into packaging bags, relying on experience to control the weight. This method was not only extremely labor-intensive, with workers easily fatigued from repetitive mechanical actions, but also extremely inefficient. In addition, errors in human judgment led to large weight deviations in each bag of castable, resulting in poor product quality consistency and making it difficult to meet the strict requirements of industrial production for product standardization.

[0004] With technological advancements, some rudimentary packaging equipment has emerged, such as devices with only basic material feeding functions. Materials fall from a high hopper through a simple pipe into the packaging bag below. However, such equipment cannot pre-treat the materials, leaving lumps and large particles in the castable uncrushed, affecting its performance during use. Moreover, in terms of quantitative control, these devices either lack a quantitative mechanism, relying entirely on manual shut-off of the feeding valve, leading to inaccurate metering; or they employ simple volumetric metering, controlling the material quantity through a fixed-size hopper. However, due to differences in the size and bulk density of the castable particles, the actual bagged weight fluctuates significantly. During the packaging process, material leakage and dust generation are prominent issues, resulting in material waste, pollution of the production environment, and harm to workers' health.

[0005] In addition, although some existing quantitative packaging devices have been improved, they are complex in structure, expensive, difficult to maintain, and have a high failure rate. For small and medium-sized enterprises, the purchase and use costs are beyond their affordability, which limits their widespread application. In view of the above problems, it is urgent to develop an efficient, accurate, environmentally friendly and cost-controllable quantitative packaging device for high-temperature resistant castables to meet the industry's demand for high-quality and standardized high-temperature resistant castable products. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a quantitative packaging device for high-temperature resistant castables, which solves the problems in the prior art where the equipment cannot pre-treat the material, and the castable may contain lumps, large particles, etc. that are not crushed, affecting its performance during use. Moreover, in terms of quantitative control, such equipment either lacks a quantitative mechanism and relies entirely on manually closing the discharge valve, resulting in inaccurate quantitative control; or it adopts a simple volumetric quantitative control method, which controls the amount of material through a fixed-size hopper, but due to the differences in the size and bulk density of the castable particles, the actual bagged weight fluctuates significantly.

[0007] According to one aspect, at least one embodiment of the present disclosure provides a quantitative packaging device for high-temperature resistant castables, comprising: A processing table, on which a processing plate is provided; A grinding and pulverizing assembly, wherein the grinding and pulverizing assembly is disposed on the processing plate; A discharge packaging assembly is disposed at the bottom of the processing plate; The grinding and pulverizing assembly includes a feed pipe disposed on the processing plate. A feed hood is provided on the upper end face of the feed pipe. A pulverizing spiral blade is disposed inside the feed pipe. A drive shaft is disposed inside the feed pipe. A feed spiral blade is mounted on the drive shaft. The feed spiral blade and the pulverizing spiral blade are staggered at intervals.

[0008] As a further technical solution, a telescopic hydraulic cylinder is provided on the processing table, and the telescopic end of the telescopic hydraulic cylinder is fixedly connected to the processing plate.

[0009] As a further technical solution, the discharge packaging assembly includes a collection cover, a positioning tube is provided on the lower end face of the processing plate, a telescopic tube is provided inside the positioning tube, and the telescopic tube is sealed and inserted into the collection cover.

[0010] As a further technical solution, a positioning plate is provided inside the feed pipe, and a discharge port is provided on the positioning plate. A rotating disk is provided on the inner side wall of the feed pipe, and a discharge port is opened on the rotating disk. The position of the discharge port corresponds to that of the discharge port.

[0011] As a further technical solution, an output motor is provided on the lower end face of the positioning plate, the telescopic end of the output motor is inserted into the inside of the feed tube, and the output end of the output motor is fixedly connected to the drive shaft.

[0012] As a further technical solution, the output motor is provided with a motor platform, the motor platform is mounted on the positioning plate, the rotating disk has a drive port, and the drive port is fitted onto the motor platform.

[0013] As a further technical solution, a drive handle is provided on the lower end face of the rotating disk, and a screwing plate is provided on the drive handle.

[0014] As a further technical solution, the side wall of the telescopic tube is provided with a downward driving plate, and the lower end face of the telescopic tube is provided with a sealing ring gasket.

[0015] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, the material dropping structure of the positioning plate and the rotating disk can flexibly control the amount of material falling. By precisely adjusting the opening size and time, the weight of each bag of casting material can be accurately controlled, completely changing the error problem of traditional manual packaging based on experience, ensuring product weight consistency, and the material conveying and crushing processes are carried out simultaneously. The crushing spiral blade and the feeding spiral blade work together, and the material pretreatment and conveying can be completed without additional processes, significantly shortening the packaging process time, greatly improving the packaging efficiency per unit time, and reducing the intensity of manual labor.

[0016] 2. In this disclosure, the sealed insertion design of the telescopic tube and the collection cover, combined with the bottom sealing ring gasket, can fit tightly with the container during packaging, effectively preventing material leakage and dust escaping. This reduces raw material loss and improves the workshop working environment. The telescopic cylinder can flexibly adjust the height of the processing plate, allowing the equipment to adapt to packaging containers of different specifications. It can meet various packaging needs without replacing core components, enhancing the versatility of the equipment and the operational flexibility of the production line. Attached Figure Description

[0025] like Figures 1-4 As shown, it illustrates a quantitative packaging device for high-temperature resistant castables according to this disclosure, comprising: Processing table 1, on which processing plate 2 is provided; Grinding and crushing component 3 is mounted on processing plate 2; The discharge packaging component 4 is located at the bottom of the processing plate 2; The grinding and crushing assembly 3 includes a feed pipe 3-1, which is mounted on the processing plate 2. A feed cover 3-2 is provided on the upper end face of the feed pipe 3-1. A crushing spiral blade 3-3 is provided inside the feed pipe 3-1. A drive shaft 3-4 is provided inside the feed pipe 3-1. A feed spiral blade 3-5 is mounted on the drive shaft 3-4. The feed spiral blade 3-5 and the crushing spiral blade 3-3 are staggered at the intervals.

[0026] The discharge packaging component 4 includes a collection cover 4-1, a positioning tube 4-2 is provided on the lower end face of the processing plate 2, a telescopic tube 4-3 is provided inside the positioning tube 4-2, and the telescopic tube 4-3 is sealed and inserted into the collection cover 4-1.

[0027] In some examples, the processing table 1 serves as the basic support structure for the entire device. The processing table 1 must possess sufficient strength and stability to bear the weight and vibration of the processing plate 2 and other components during operation. It can be constructed from high-quality steel through welding or assembly. The table surface should be flat and smooth to avoid affecting subsequent operations. The processing plate 2 is fixedly installed on the processing table 1. Its material can be selected according to the actual usage environment and requirements; for example, stainless steel can effectively prevent corrosion. The thickness and dimensions of the processing plate 2 need to be customized according to the installation requirements of the grinding and crushing component 3 and the discharge packaging component 4 to ensure that each component is securely installed and easy to operate. The feed pipe 3-1 is vertically installed on the processing plate 2. The diameter needs to be designed according to the feed rate and flow rate requirements of the high-temperature resistant castable. Generally, a circular cross-section is adopted to ensure smooth material flow. The material of the feed pipe 3-1 should have good wear resistance. Wear-resistant alloy steel or pipes lined with wear-resistant ceramics can be selected. The feed hood 3-2 is welded or bolted to the upper end face of the feed pipe 3-1. The feed hood 3-2 is designed in the shape of a funnel, and its opening size should be large enough to facilitate the pouring of the high-temperature resistant castable and effectively prevent the material from spilling during the pouring process. The crushing spiral blade 3-3 is fixed to the drive shaft 3-4 inside the feed pipe 3-1 by welding or key connection. The blade shape and pitch of the crushing spiral blade 3-3 need to be determined according to the properties of the castable (e.g., ...). The design is optimized for particle size, hardness, etc., and generally uses spiral blades with sharp edges to improve the crushing effect. The spacing between adjacent blades should be moderate to ensure effective material conveying and thorough grinding. The drive shaft 3-4 must penetrate the inside of the feed pipe 3-1, and its two ends are mounted on the pipe wall of the feed pipe 3-1 via bearings to ensure smooth rotation. The drive shaft 3-4 should be made of high-strength alloy steel and heat-treated to improve its strength and wear resistance. One end of the drive shaft 3-4 is connected to a power source (such as a motor) via a coupling, and the power source provides rotation. The power source drives the feeding spiral blade 3-5 and the crushing spiral blade 3-3 to rotate. The feeding spiral blade 3-5 is also mounted on the drive shaft 3-4 and is staggered with the crushing spiral blade 3-3 at intervals. The function of the feeding spiral blade 3-5 is to push the high-temperature resistant casting material poured into the feeding hood 3-2 downward along the feeding pipe 3-1. Its pitch and blade shape are different from those of the crushing spiral blade 3-3. Generally, the pitch is larger and the blades are wider to achieve efficient material conveying. The staggered arrangement of the feeding spiral blade 3-5 and the crushing spiral blade 3-3 ensures that the material is continuously subjected to the action of the two spiral blades during the conveying process, which can not only achieve effective material propulsion, but also fully grind and crush the material.

[0028] The collecting hood 4-1 is designed in a funnel shape, and its opening size should be adjusted according to the size of the packaging container to ensure that the packaging container can be smoothly placed under the collecting hood 4-1 to receive materials. The material of the collecting hood 4-1 can be stainless steel or other corrosion-resistant materials to ensure that it will not be corroded by the materials during the collection of high-temperature castable. The collecting hood 4-1 is fixed to the bottom of the positioning tube 4-2 by welding or bolting, forming a sealed connection with the positioning tube 4-2 to prevent material leakage. The positioning tube 4-2 is installed vertically on the lower end face of the processing plate 2. The diameter and length of the positioning tube 4-2 need to be designed according to the size and working stroke of the telescopic tube 4-3. The material of the positioning tube 4-2 should have good strength and sealing performance, and metal pipes can be selected. The positioning tube 4-2 and the processing plate 2 can be fixed by welding or flange connection to ensure a firm and reliable connection. The telescopic tube 4-3... The telescopic tube 4-3 is fitted inside the positioning tube 4-2 and can slide up and down within the positioning tube 4-2 to achieve the telescopic function. The telescopic tube 4-3 can be made of the same metal material as the positioning tube 4-2, and its wall thickness needs to be designed according to the working pressure and strength requirements. A sealing device (such as a sealing ring) can be installed between the outer wall of the telescopic tube 4-3 and the inner wall of the positioning tube 4-2 to ensure that no material leakage occurs during the telescopic process. The sealing ring gasket 11 is installed on the lower end face of the telescopic tube 4-3. The sealing ring gasket 11 should be made of a material with good sealing performance and high temperature resistance, such as rubber or silicone. The function of the sealing ring gasket 11 is to further enhance the sealing effect and prevent material leakage when the collection cover 4-1 is attached to the packaging container. The thickness and width of the sealing ring gasket 11 need to be designed according to the actual sealing requirements to ensure that it can effectively fill the gap between the collection cover 4-1 and the packaging container.

[0029] like Figures 1-4 As shown in the figure, this embodiment proposes that a telescopic cylinder 3-6 is provided on the processing table 1, and the telescopic end of the telescopic cylinder 3-6 is fixedly connected to the processing plate 2.

[0030] In some examples, the cylinder body of the telescopic cylinder 3-6 is fixed to the processing table 1 by a mounting base, and the telescopic end of the telescopic cylinder 3-6 is fixedly connected to the processing plate 2. The model and specifications of the telescopic cylinder 3-6 need to be selected according to the weight of the processing plate 2 and other components and the lifting stroke requirements to ensure that sufficient power can be provided to push the processing plate 2 to move up and down. The mounting base and the processing table 1 can be connected by bolts for easy installation and disassembly. The working principle of the telescopic cylinder 3-6 is to drive the piston to reciprocate in the cylinder body through the input and output of hydraulic oil, thereby driving the telescopic end to achieve the lifting action. During use, a corresponding hydraulic pump station and control system are required to accurately control the working state of the telescopic cylinder 3-6.

[0031] For example, such as Figure 3As shown, a positioning plate 4-4 is provided inside the feed pipe 3-1, and a discharge port 4-5 is provided on the positioning plate 4-4. A rotating disk 4-6 is provided on the inner side wall of the feed pipe 3-1, and a discharge port 4-7 is opened on the rotating disk 4-6. The positions of the discharge port 4-7 and the discharge port 4-5 are corresponding.

[0032] In some examples, the positioning plate 4-4 is installed inside the feed pipe 3-1. The position and size of the outlet 4-5 on the positioning plate 4-4 need to be precisely matched with the discharge port 4-7 on the rotating disk 4-6. The positioning plate 4-4 can be fixed to the inner wall of the feed pipe 3-1 by bolts or welding. Its material can be the same wear-resistant material as the feed pipe 3-1. The rotating disk 4-6 can rotate around its own axis on the inner wall of the feed pipe 3-1. The discharge port 4-7 on the rotating disk 4-6 corresponds to the position of the outlet 4-5 on the positioning plate 4-4. The rotation of the rotating disk 4-6 can be achieved in various ways, such as manual operation or electric drive. The material of the rotating disk 4-6 should have certain wear resistance and strength, and can be metal or high-strength engineering plastic.

[0033] For example, such as Figure 3 As shown, an output motor 5 is provided on the lower end face of the positioning plate 4-4. The telescopic end of the output motor 5 is inserted into the inside of the feed pipe 3-1. The output end of the output motor 5 is fixedly connected to the drive shaft 3-4. A motor platform 6 is provided on the output motor 5. The motor platform 6 is set on the positioning plate 4-4. A drive port 7 is opened on the rotating disk 4-6. The drive port 7 is fitted on the motor platform 6.

[0034] In some examples, the output motor 5 is mounted on the lower end face of the positioning plate 4-4 via the motor mount 6. The output end of the output motor 5 is inserted into the feed pipe 3-1 and fixedly connected to the drive shaft 3-4. The model and power of the output motor 5 need to be selected according to the torque and speed required by the drive shaft 3-4 to ensure that it can provide sufficient power to drive the drive shaft 3-4 to rotate smoothly. The motor mount 6 and the positioning plate 4-4 can be connected by bolts to facilitate the installation, disassembly and maintenance of the motor. The motor mount 6 is used to fix the output motor 5. Its shape and size need to be designed according to the shape of the output motor 5. It is generally made of welded steel plate and has sufficient strength and stability. The connection between the motor mount 6 and the positioning plate 4-4 should be firm and reliable to prevent loosening during motor operation.

[0035] For example, such as Figure 3 As shown, a drive handle 8 is provided on the lower end face of the rotating disk 4-6, and a screwing plate 9 is provided on the drive handle 8.

[0036] In some examples, the drive handle 8 is installed on the lower end face of the rotating disk 4-6. The drive handle 8 is equipped with a screw plate 9 to facilitate the operator to manually rotate the rotating disk 4-6. The length and shape of the drive handle 8 should conform to ergonomic design to facilitate the operator to apply force. The surface of the screw plate 9 can be designed with a non-slip texture to increase the friction between the operator's hand and the screw plate 9, ensuring the accuracy and stability of the operation.

[0037] For example, such as Figure 4 As shown, the side wall of the telescopic tube 4-3 is provided with a downward driving plate 10, and the lower end face of the telescopic tube 4-3 is provided with a sealing ring gasket 11.

[0038] In some examples, the pressure drive plate 10 is installed on the side wall of the telescopic tube 4-3. The function of the pressure drive plate 10 is to push the telescopic tube 4-3 downward by external power (such as a cylinder or electric push rod) so that the collection cover 4-1 fits tightly with the packaging container to prevent material leakage during the packaging process. The shape and size of the pressure drive plate 10 need to be designed according to the connection requirements of the external power device. Generally, it adopts a flat plate structure and is fixed to the side wall of the telescopic tube 4-3 by bolts or welding.

[0039] In use, the high-temperature resistant castable is poured into the feed pipe 3-1 through the feed hood 3-2. The output motor 5 is started, which drives the drive shaft 3-4 to rotate. The feed spiral blade 3-5 and the crushing spiral blade 3-3 on the drive shaft 3-4 rotate accordingly. The feed spiral blade 3-5 pushes the material down along the feed pipe 3-1. During this process, the staggered crushing spiral blades 3-3 use their sharp edges and unique spiral structure to grind and crush the material, breaking larger particles of castable into fine particles that meet packaging requirements.

[0040] Quantitative control: The initial positions of the discharge port 4-5 on the positioning plate 4-4 and the drop port 4-7 on the rotating disk 4-6 correspond. The crushed material falls into the collection hood 4-1 below through the discharge port 4-5 and the drop port 4-7. When it is necessary to control the discharge amount, the drive handle 8 can be manually turned to rotate the rotating disk 4-6, so that the drop port 4-7 and the discharge port 4-5 are misaligned, thus blocking the material from falling; or according to the preset quantitative requirements, the electric drive of the rotating disk 4-6 can precisely control the corresponding time and opening size of the drop port 4-7 and the discharge port 4-5 to achieve quantitative control of the discharge amount.

[0041] Material unloading and packaging: In the material unloading and packaging stage, the telescopic cylinder 3-6 can adjust the height of the processing plate 2 by hydraulic drive according to the height of the packaging container, so that the collection cover 4-1 is adapted to the position of the packaging container. When the packaging container is in place, external power (such as a cylinder or electric push rod) pushes the downward drive plate 10, so that the telescopic tube 4-3 slides downward in the positioning tube 4-2, driving the collection cover 4-1 to descend and fit tightly against the packaging container. The sealing ring gasket 11 further enhances the sealing effect and prevents material leakage. At this time, a certain amount of high temperature resistant casting material falls from the collection cover 4-1 into the packaging container, completing the packaging process.
