Description

Technical Field

[0001] The utility model relates to the technical field of batching devices, in particular to a precise metering device for electrode paste batching. Background Art

[0002] Electrode paste is a conductive material used in electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces. Electrode paste is also called self-baking electrode. It relies on the heat in the submerged arc furnace to complete the baking. Therefore, the key to the use of electrode paste is to match the electrode consumption rate with the baking rate. Due to the development of submerged arc furnace technology, it is gradually developing in the direction of large-scale and closed. During the baking process, the electrode has reduced the more conductive heat and radiant heat obtained by the open furnace type in the past to only conductive heat. Therefore, the heat obtained by the electrode from the furnace is greatly reduced. This requires improving the sintering performance of the electrode paste to make up for this deficiency. The electrode paste needs to be batched before forming.

[0003] The publication number in the existing public technology is: CN213408588U. A batching device for electrode paste molding includes a base, two symmetrically arranged vertical plates are fixedly installed on the top of the base, and the same batching chamber is fixedly installed on the top of the two vertical plates. The batching chamber is hollow, and two symmetrically arranged feeding components are arranged inside the batching chamber. Two symmetrically arranged intermediate tubes are fixedly installed on the bottom inner wall of the batching chamber, and the bottoms of the two intermediate tubes extend to the bottom of the batching chamber. Two symmetrically arranged horizontal plates are fixedly installed on the top of the base, and the same metering barrel with an opening on the top is rotatably installed on one side of the two horizontal plates close to each other, and there are two metering barrels. Compared with the traditional method of manually weighing the electrode paste ingredients, the utility model has a high degree of automation, low labor intensity, greater accuracy in weighing the electrode paste ingredients, and can maximize the performance of the electrode paste after molding.

[0004] However, the above patent still has certain shortcomings during use: although it can detect the amount of delivery through a gravity sensor, when it detects that the ingredients meet the standard, since the conveyor shaft is feeding continuously, there is a problem that the conveyor shaft is not stopped in time, resulting in some raw materials continuing to be added, which is easy to cause excessive addition of materials, resulting in excessive dosage, thereby affecting the overall ratio of the ingredients and the production quality of the electrode paste. Moreover, when the ingredients are subsequently added to the metering barrel, some ingredients are easy to adhere to its inner wall, which makes it impossible to completely discharge them, resulting in a reduction in the amount that can be used subsequently. At the same time, the residue of ingredients will also affect the subsequent addition ratio of ingredients, resulting in the overall ingredient accuracy being not high enough.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0032] In one embodiment, a fixed seat 15 is fixedly installed in the middle position of the bottom of the surface of the hopper 27, and a rotating rod in the middle position of the fixed seat 15 is connected to a driving shaft 6. The top of the driving shaft 6 is connected to the driving structure 7 through a gear. Scrapers 4 are symmetrically installed on the surfaces of both sides of the driving shaft 6, and the scrapers 4 are in contact with the inner wall of the hopper 27. The scrapers 4 are arranged to scrape off the residual raw materials on the inner wall of the hopper 27, reduce the residue, and improve the proportioning effect of the raw materials. The driving structure 7 can refer to the use of equipment such as the motor 13. The specific type of the motor 13 can be adjusted according to different needs. One group of connected gears is horizontal and the other group is vertical, and the driving structure 7 is arranged on the outer surface of the batching barrel 5. Similarly, the type of gears used can also be adjusted according to needs, such as conventional gears or bevel gears, which can be adjusted according to needs.

[0033] In one embodiment, a discharge port 19 is opened at the bottom surface of the batching barrel 5, and a sealing plate 21 is slidably connected to the inner position of the discharge port 19. First electric push rods 17 are symmetrically installed on both sides of the sealing plate 21 at the bottom surface of the batching barrel 5, and a second weighing sensor 18 is installed at the top surface of the sealing plate 21. The second weighing sensor 18 is used to detect the amount of raw materials inside the hopper 27 to determine whether the raw materials meet the standards.

[0034] In one embodiment, a feed port 9 is fixedly installed at one side of the top of the batching barrel 5. The provision of the feed port 9 facilitates the addition and use of various raw materials.

[0035] In one embodiment, the size of the discharge port 10 is the same as the size of the feeding port 11. The same size ensures that the raw materials can be discharged and used smoothly through the two ports, which is convenient for the subsequent proportioning and adding of raw materials.

[0036] In one embodiment, a mixing hopper 20 is installed below the batching barrel 5 on the surface of the base 1. The mixing hopper 20 is provided to mix raw materials with various proportions for use, so as to facilitate the subsequent production of electrode paste.

[0037] In one embodiment, the collecting hopper 27 is a conical structure, and the conical structure is provided to facilitate the discharge of raw materials for use and improve the efficiency of discharge.

[0038] In one embodiment, the storage bin 8 is a semi-conical structure, and the semi-conical structure is provided to collect the raw materials to the bottom position through the inclination of the surface, thereby facilitating subsequent discharge and use.

[0039] Working principle: In actual use, personnel can add various ingredients needed to produce electrode paste to the corresponding internal positions of the ingredient barrel 5 through the feed ports 9 at different positions. At this time, the added raw materials will enter the storage bin 8. At this time, personnel can control the operation of the motors 13 at different positions according to the required amount of raw materials, and then drive the adjustment disk 14 to rotate through the operation of the motor 13. When the adjustment disk 14 rotates, the feeding port 11 on its surface is intermittently aligned with the discharge port 10 on the bottom surface of the storage bin 8. At this time, the internal raw materials can be smoothly discharged. It is convenient to add materials. Since the intermittent feeding operation is adopted, it can be stopped in time after the raw material feeding amount reaches the standard, so as to avoid excessive addition of raw materials due to untimely stagnation. As the raw materials continue to fall, the amount of raw materials inside the hopper 27 will continue to increase. At this time, the second weighing sensor 18 on the surface of the sealing plate 21 at the bottom of the hopper 27 can detect the weight of the raw materials inside the hopper 27, so as to achieve accurate addition of raw materials. After the raw materials are added in place, the motor 13 can be controlled to stop in time. At this time, if some raw materials are not stopped in time, resulting in excessive addition of raw materials, At this time, the blocking plate 26 can be opened from the flow slot 24 by recovering the third electric push rod 28 in the temporary storage chamber 22 on both sides of the hopper 27, so that the raw materials inside the hopper 27 flow into the temporary storage chamber 22. At this time, the first weighing sensor 16 inside it can detect the amount of raw materials entering. When it is detected that the amount of stored raw materials is the same as the previous excess raw materials, the structure runs in the reverse direction, so that the blocking plate 26 seals the temporary storage chamber 22, thereby ensuring that the amount of raw materials inside the hopper 27 will not exceed the standard, thereby ensuring the subsequent ratio between different raw materials and improving the overall ratio. At the same time, when the raw materials are discharged later, the operation of the driving structure 7 can drive the scraper 4 to scrape the inside of the hopper 27, and then scrape off the raw materials attached to the surface, to prevent the residual raw materials from reducing the actual amount of falling, and further improve the proportioning effect of the raw materials. After all the processing is completed, the raw materials in the temporary storage chamber 22 can be pushed out by the movement of the push plate 25, which is convenient for subsequent secondary proportioning and avoids the waste of raw materials. The overall use effect of the device is improved. The device as a whole has the advantages of excess material diversion, scraping off attached materials, and high proportioning accuracy.
