Description

Technical Field

[0001] The utility model mainly relates to the technical field related to stone mills, in particular to a mixed feeding system of a stone mill. Background Art

[0002] Stone mill can be used to grind peanuts, soybeans, sesame, etc. It is a commonly used material processing tool. In the process of industrial stone mill processing, it is generally necessary to configure multiple stone mills to improve production efficiency. Stone mills can also process different materials according to demand.

[0003] In the prior art, the stone mill is mostly fed with a vacuum pipeline, that is, the material is first sucked into a vacuum tank by vacuuming, and then transported to the hopper of the stone mill through the vacuum tank. In the prior art, each stone mill is generally used to process only one material, so its corresponding feeding system is a single material conveyor. When multiple materials need to be mixed (such as the famous 28 sauce, which is 20% sesame and 80% peanuts), the prior art generally grinds a single material first and then mixes it after processing. The process is cumbersome, and the mixing effect is not as good as the direct mixing effect. Therefore, it is necessary to improve the existing stone mill feeding pipeline system so that it can be mixed or fed separately to meet market demand. Utility Model Content

[0004] In order to solve the shortcomings of the current technology, the utility model combines the existing technology and, based on practical applications, provides a mixed feeding system for a stone mill. The system can accurately mix a variety of materials and send them to the stone mill for processing. It can automatically feed and mix the materials before processing. The feeding system can choose to feed them individually or mix them according to actual usage requirements. The overall structure is compact and flexible to use.

[0007] Furthermore, among the multiple millstone hoppers of the feeding system, at least two discharge pipes for conveying different materials are correspondingly arranged above some or all of the millstone hoppers, and different materials are quantitatively conveyed to the millstone hoppers through screw feeders at the ends of at least two discharge pipes.

[0008] Furthermore, the discharge port of each intermediate hopper is connected to at least two discharge pipes, and the multiple discharge pipes of each intermediate hopper are correspondingly connected to the tops of multiple stone mill hoppers.

[0009] Furthermore, the millstones are arranged in two parallel rows, each row includes a plurality of millstones, and the intermediate hopper is arranged above the middle of the two rows of millstones.

[0010] Furthermore, the feed pipe is arranged to be inclined downward.

[0011] Furthermore, vacuum tanks corresponding to different materials are arranged alternately and in parallel.

[0012] Furthermore, the feeding system also includes a vortex blower, the vortex blower is connected to a vacuum pipe, and the vacuum pipe is connected to each vacuum tank through a plurality of branch pipes.

[0013] Furthermore, a second gate valve is provided on the branch pipeline corresponding to the vacuum pumping pipe near the vacuum tank, and a first gate valve is provided on the feeding pipeline corresponding to the vacuum tank.

[0014] Beneficial effects of the utility model:
