Description

Technical Field

[0001] The utility model relates to the technical field of powder raw material proportioning devices, and specifically, to a raw material proportioning device for 995 alumina ceramic granulating powder. Background Technique

[0002] Alumina ceramics, with a series of excellent characteristics such as high mechanical strength, high volume resistivity, good electrical insulation, high strength, wear resistance, and oxidation resistance, are increasingly widely used in the modern industrial field. Especially in wear-resistant and corrosion-resistant components in the mechanical and chemical industries, crucible protection tubes, refractory materials used in the metallurgical industry, substrate insulators, radar radomes, microwave electrolytes, and other ceramic components for the electronics industry, alumina ceramics have become the preferred material due to their excellent performance.

[0003] In the production process of alumina ceramics, the proportioning of raw materials and granulation technology are the key factors affecting product quality. When preparing alumina ceramic granulating powder, in order to ensure more accurate proportioning of various raw materials, corresponding raw material proportioning devices are usually used. The raw material proportioning devices on the market all use load cells to complete the weighing operation to achieve the effect of precise control of the quantity, and this type of raw material proportioning device generally uses a corresponding cylinder to hold the raw materials in advance, and weighs the whole cylinder and the raw materials inside the cylinder to achieve the effect of precise control of the batching quantity.

[0004] However, after the cylinder of this type holds the raw materials and finishes weighing, with the start of the discharging operation, generally, the valve at the bottom of the cylinder is directly opened for discharging. However, in the actual discharging process, due to the lack of corresponding scraping and components to promote the falling of the raw materials at this cylinder part, the raw materials will adhere to the inner wall of the cylinder, and it is difficult for the raw materials to fall directly by their own gravity. At this time, the amount of raw materials falling out of the cylinder will be small. Without people's knowledge, the discharging amount will be less than the previously weighed amount, resulting in inaccurate batching and affecting the use effect. In view of this, we have proposed a raw material proportioning device for 995 alumina ceramic granulating powder. Summary of the Utility Model

On the upper surface of the support platform 1, a plurality of groups of weighing sensors 11 arranged linearly at equal intervals are fixedly installed. The through holes 10 are located at the center positions of each group of weighing sensors 11. A containing cylinder 3 is inserted and fitted in the through holes 10. A support ring 30 is fixedly installed on the bottom cylinder of the containing cylinder 3, and the bottom surface of the support ring 30 is fixedly installed on the corresponding weighing sensor 11, which is convenient for using the weighing sensor 11 to perform weighing operations;

[0028] Specifically, a discharge hopper 31 is fixedly installed at the bottom end of the containing cylinder 3, a discharge pipe 32 is fixedly installed at the bottom end of the discharge hopper 31, and a discharge valve 33 is fixedly installed on the discharge pipe 32. A screw feeder 2 is arranged on one side of the containing cylinder 3. The discharge end of the screw feeder 2 is fixedly installed with a discharge pipe 20, and an electric valve 21 is fixedly installed on the discharge pipe 20. The discharge pipe 20 is inserted into the containing cylinder 3, which is convenient for transporting raw materials into the containing cylinder 3 for weighing operations;

[0029] Specifically, a reduction motor 35 is arranged at the top of the containing cylinder 3. The end of the output shaft of the reduction motor 35 is fixedly installed with a long shaft 36, and a scraping plate 37 is fixedly installed on the long shaft 36, which is convenient for using the scraping plate 37 to scrape the raw materials on the inner wall of the containing cylinder 3, so that the raw materials in the containing cylinder 3 can fall out more smoothly along the discharge pipe 32.

[0030] In this embodiment, a plurality of support legs 12 arranged in a matrix are fixedly installed on the bottom surface of the support platform 1, and the support legs 12 are used for supporting operations.

[0031] Specifically, a top plate 34 is fixedly installed on the inner wall of the top cylinder of the containing cylinder 3, and the reduction motor 35 is fixedly installed at the center position of the top plate 34; a blanking hole 371 is arranged between the bottom end rod bodies of the scraping plate 37 and the long shaft 36, and the blanking hole 371 is used for blanking operations, so that the raw materials can fall out more smoothly along the scraping plate 37 and the blanking hole 371 at the bottom.

[0032] Further, a rotating shaft 13 is rotatably connected between two corresponding front and rear support legs 12, and a conveyor belt 131 connected end to end is connected between the left and right rotating shafts 13. The end of one of the rotating shafts 13 is coaxially provided with a driving motor 14, and the discharge pipe 32 is located directly above the conveyor belt 131, which is convenient for using the conveyor belt 131 to convey the raw materials falling from the discharge pipe 32.

[0033] In addition, discharge plates 15 are fixedly installed between the left and right support legs 12. The bottom end of the discharge plate 15 extends to the upper surface of the conveyor belt 131. A discharge gap 151 is provided between the front and rear discharge plates 15. The discharge gap 151 is directly above the middle position of the conveyor belt 131. The discharge plate 15 is arranged to be inclined downward at an angle of 45° to 60°, and is used to prevent the raw materials from falling out from the side part of the conveyor belt 131.

[0034] It should be noted that a batching control module 16 is fixedly installed on one of the support legs 12. The batching control module 16 is used to control the operation of the discharge valve 33. The weighing sensor 11 is used to monitor the amount of raw materials in the holding cylinder 3 in real time. The batching control module 16, as the core of the entire device, is responsible for controlling the batching process of the raw materials. This module includes a processor, a control program, and a batching algorithm. The processor calculates and outputs a batching instruction through the control program according to the preset raw material formula and the real-time data of the raw materials stored in the holding cylinder 3. The electric valve 21 completes the opening or closing operation according to the instruction of the batching control module 16 to implement specific batching operations. Specifically, the weighing sensor 11 first weighs the holding cylinder 3, and then after setting is completed in the batching control module 16 according to user needs, the batching control module 16 controls the electric valve 21 to open and at the same time controls the screw feeder 2 to work. At this time, discharging starts. After discharging, the weighing value detected by the weighing sensor 11 is continuously increasing. When the weighing value detected by the weighing sensor 11 reaches the set standard, the batching control module 16 controls the electric valve 21 to close and controls the screw feeder 2 to stop working, completing the accurate batching operation.

[0035] In practical applications, the management personnel first input information such as the configuration parameters of the raw materials through the display screen and buttons on the batching control module 16. The batching control module 16 calculates and outputs a batching instruction according to this information. The electric valve 21 and the screw feeder 2 complete the opening and closing operations according to the instruction to unload the corresponding amount of raw materials, and the weighing sensor 11 performs timely weighing operations.

[0036] Finally, it should be noted that the components such as the weighing sensor 11, the batching control module 16, and the electric valve 21 involved in the present invention are all general standard components or components known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the adapted controllers and power supplies, are connected by wires. The specific connection means should refer to the working principle of the present invention. The electrical components are electrically connected in the order of their working sequence. Their detailed connection means are all well-known technologies in the art.

[0037] When the raw material proportioning device of 995 alumina ceramic granulating powder of the present utility model is in use, first close the discharge valve 33, then open the electric valve 21, and start the screw feeder 2 to make it work. When the screw feeder 2 works, it starts to convey the raw materials. The raw materials fall from the end of the discharge pipe 20 into the holding cylinder 3. At this time, use the weighing sensor 11 to weigh the overall weight on the holding cylinder 3. When the amount of raw materials in the holding cylinder 3 reaches the required amount, the electric valve 21 is closed and the screw feeder 2 stops working to stop discharging. At this time, the amount of raw materials in the holding cylinder 3 is the required amount. Then open the discharge valve 33. At this time, the raw materials in the holding cylinder 3 can fall out along the end of the discharge pipe 32 onto the conveyor belt 131. At the same time, connect the reduction motor 35 to an external power supply and make it work. When the reduction motor 35 works, the output shaft on it rotates to drive the long shaft 36 to rotate, and further drives the scraping plate 37 to rotate, so as to scrape the raw materials on the inner wall of the holding cylinder 3. In addition, connect the drive motor 14 to an external power supply and make it work. When the drive motor 14 works, the output shaft on it rotates to drive the rotating shaft 13 and the conveyor belt 131 to rotate, so as to convey the raw materials outwards.
