Description

Technical Field

[0001] This utility model relates to the field of feeding valve technology, specifically a continuous feeding valve for powder materials. Background Technology

[0002] In modern industrial production, continuous powder feeding valves are core equipment in the material conveying process and are widely used in many industries such as food, pharmaceuticals, chemicals, and building materials. From the quantitative conveying of sugar powder and flour in food production lines to the precise metering of drug powders in the pharmaceutical industry, from the stable transmission of corrosive powders in the chemical field to the efficient conveying of large quantities of powdered raw materials in the building materials industry, the performance of the feeding valve directly affects production efficiency, product quality, and enterprise economic benefits. Therefore, continuous powder feeding valves are required.

[0003] Traditional powder feeding valves mostly use a single rotating shaft to drive the feeding blades to push the powder. However, when the powder clumps due to moisture, it is easy to accumulate inside the valve body. The increased viscosity of the powder inside the valve can also cause blockage inside the valve body, and in severe cases, it may even be impossible to feed the powder. Utility Model Content

[0004] The purpose of this utility model is to provide a continuous powder feeding valve to solve the problems mentioned in the background art, such as when powder clumps due to moisture, it easily accumulates inside the valve body, and the increased viscosity of the powder inside the valve can easily cause blockage, even preventing feeding in severe cases. To achieve the above objective, this utility model provides the following technical solution: a continuous powder feeding valve, including a valve body frame;

[0005] The scraping assembly includes a feeding bin, which is located inside the valve body frame. A scraper is installed inside the feeding bin. A limit ring is fixedly connected to one side of the scraper, and an extension tube is fixedly connected to the other side of the scraper. An interlocking groove is provided inside the extension tube, and a scraper rotating rod is fixedly connected to the other side of the extension tube. A scraper motor is installed at the other end of the scraper rotating rod.

[0006] The feeding assembly includes feeding blades installed inside the feeding bin, and a feeding motor is installed on one side of the feeding blades.

[0007] More preferably, the scraping assembly is located on one side of the valve body frame, and the feeding assembly is located on one side of the valve body frame. By installing the scraping assembly, the scraping motor can drive the scraping rod to rotate, causing the scraping plate to rotate in the feeding bin inside the valve body frame. The scraping plate is in close contact with the inner wall of the feeding bin, which can scrape off the powder adhering to the bin wall in time, preventing material accumulation and blockage. At the same time, the limiting ring on the scraping plate can limit its range of motion, ensuring stable operation of the scraping work. The extension tube and its internal fitting groove facilitate the splicing and fitting of the scraping plate and the feeding blade, and the rotation speed of the feeding blade can be staggered with that of the scraping plate. This dual-shaft structure makes it difficult for powder to stick and accumulate inside, which is conducive to continuous powder feeding.

[0008] In a further preferred embodiment, the feeding assembly further includes a fitting block, which is fixedly connected to one side of the feeding blade and is adapted to the fitting groove. An extension rod is fixedly connected to the other side of the feeding blade, and the other end of the extension rod is connected to the transmission end of the feeding motor. A first bearing plate is fixedly connected to the bottom of the scraper motor, and a second bearing plate is fixedly connected to the bottom of the feeding motor. By installing the feeding assembly, the feeding motor can drive the extension rod to rotate, thereby causing the feeding blade to rotate in the feeding bin and continuously convey the powder outward, completing the continuous feeding operation. The scraper motor and the feeding motor are fixed by the first bearing plate and the second bearing plate, respectively. The design of the fitting block and the fitting groove allows the feeding blade and the scraper to be easily assembled and disassembled, thereby improving practicality.

[0009] More preferably, the top of the valve body frame is provided with a splicing groove, the inside of the splicing groove is provided with a splicing hole, a connecting pipe is installed inside the splicing groove, and a splicing bolt is threadedly connected inside the connecting pipe. Two connecting pipes are symmetrically distributed on the upper and lower sides of the valve body frame. The top of the first support plate and the second support plate are fixedly connected with a suspension rod. By installing the splicing groove, the connecting pipe can be conveniently embedded into the splicing groove. The connecting bolt passes through the splicing hole and is threadedly connected to the connecting pipe, so that the connecting pipe is firmly fixed to the valve body frame, which facilitates the connection of external input and output pipes. The suspension rod can be connected to an external bracket or fixed structure, thereby ensuring the stability of the valve body.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In this invention, by installing a scraper assembly, the scraper motor drives the scraper rod to rotate, which in turn drives the scraper plate to rotate in the feeding bin inside the valve body frame. The scraper plate is in close contact with the inner wall of the feeding bin, which can scrape off the powder adhering to the bin wall in time, preventing material accumulation and blockage. At the same time, the limiting ring on the scraper plate can limit its range of motion, ensuring stable operation of the scraper. The extension tube and its internal fitting groove facilitate the splicing and fitting of the scraper plate and the feeding blade. Moreover, the rotation speed of the feeding blade can be staggered with that of the scraper plate. This dual-shaft structure makes it difficult for powder to stick and accumulate inside, which is conducive to continuous powder feeding.

[0012] In this utility model, by installing the feeding assembly, the feeding motor can drive the extension rod to rotate, which in turn drives the feeding blade to rotate in the feeding bin, continuously conveying the powder outward and completing the continuous feeding operation. The scraper motor and the feeding motor are fixed by the first bearing plate and the second bearing plate, respectively. The design of the interlocking block and the interlocking groove makes it easy to assemble and disassemble the feeding blade and the scraper, thereby improving the practicality.
