Turntable type quantitative discharging device

Abstract

The invention discloses a turntable type quantitative discharging device, which comprises a storage bin. The turntable type quantitative discharging device is characterized in that the storage bin is a barrel with a circular upper part and a conical lower part, the lower edge of the lower conical part of the barrel is fixedly connected with a discharging pipe provided with a serrated bottom edge, and the outer side of the discharging pipe is fixedly provided with a bin bottom flange plate with external threads. The turntable type quantitative discharging device also comprises a cylinder which supports a supporting point outside of the storage bin so that the storage bin can rotate; a turntable assembly which is connected with the threads of the bin bottom flange plate through threads and comprises a three-claw turntable seat, a turntable arranged in the middle of the turntable seat and a rotating beam barrel; a collecting tank which is arranged below the turntable assembly and is a barrel with an upper circular part and a lower conical part; a driving host which is arranged in the middle upper part of the collecting tank; and a weighing scale which is arranged in the middle upper part of the collecting tank. The device has the advantages of simple structure, stable discharge and easy use and cleaning, can realize the smooth, accurate, rapid and automatic quantitative discharging of trace raw materials, and is applicable to the mixing and production with multiple types of powdered and particular trace raw materials and high weighing precision.

Description

technical field [0001] The invention relates to a conveying device, especially a quantitative feeding device for powder and granular matter. Background technique [0002] In the production of the feed industry, the processing of raw materials into feed products generally requires five basic production processes, namely: raw material crushing→powder, mineral and pharmaceutical raw material batching→mixing→granulation→packaging→finished product. Due to the small amount and variety of minerals and drugs used in the production process, the batching process is generally called micro-batching. Hereinafter, the same abbreviation - micro-ingredients. [0003] After nearly 20 years of development in China's feed industry, the production scale and output have undergone tremendous changes. According to the bulletin data of "China Feed Industry Information Network", by 2008, the total annual output of feed will exceed 100 million tons, and the total number of various feed production p...

[0008] 3) Differences in physical and chemical properties (both in powder form):

[0021] 1. The discharge speed and precision cannot be balanced: if the screw diameter is large, the discharge speed is fast but the precision is not high; on the contrary, the screw diameter is small, the discharge cross-sectional area is also small, the discharge accuracy is high but the speed is not fast

[0022] 2. Poor adaptability to materials: When using a screw device to make materials, for powders with good fluidity, such as calcium hydrogen phosphate of minerals, the materials are easy to discharge through the screw blade; on the contrary, if the materials with poor fluidity, Such as starch-containing drugs, milk powder, etc., which are easy to produce arches in the container and cannot be discharged; or the raw materials are agglomerated or adhered to the blade due to screw extrusion.

[0023] 3. Inconvenient to use: If due to the long storage time, the bottom of the container is prone to material arching, or the sticky material of the blade causes abnormal discharge, due to the complicated spiral structure, it is not easy to clean the blade and the residual material inside the device during use;

[0024] 4. Many power devices: each type of storage container needs to be equipped with at least one set of screw discharge mechanism, and the equipment cost is high

It shows that the defects of the above-mentioned spiral discharge mechanism make it difficult to ensure that the equipment can achieve stable and reliable discharge during use, and even cause production interruption

Other productized discharge devices (systems) also have similar problems, so they are also not suitable for feed production
