Description

Technical Field

[0001] This utility model relates to the field of centrifuge discharge technology, specifically a buffer hopper for a bottom-discharge centrifuge. Background Technology

[0002] In the crystallization industry, in order to ensure that the particle size of the crystals is not damaged during centrifugation, it is necessary to select some specific centrifuges. These centrifuges are mostly intermittent feeders, with a feed volume ranging from several hundred kilograms to several tons at a time. A silo with a buffer function is needed to slowly transport this material to the next process.

[0003] Existing silo designs mostly feature concentric truncated cones, which can cause salt bridging due to wet salt, preventing proper flow and leading to silo blockage. Adding vibration only results in more compaction when excessive salt accumulates. Therefore, this invention proposes a buffer silo for a bottom-discharge centrifuge that can solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a buffer hopper for a bottom-discharge centrifuge to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a buffer hopper for a bottom-discharge centrifuge, comprising a hopper body and a dispersing assembly, wherein the hopper body comprises an upper hopper part and a lower hopper part connected from top to bottom;

[0006] The upper part of the hopper is cylindrical and is connected to the discharge port of the centrifuge;

[0007] The lower part of the hopper is provided with a discharge port, which is rectangular in shape. The lower part of the hopper includes inclined plates on the front and rear sides and vertical plates on the left and right sides, and adjacent inclined plates and vertical plates are connected by arc plates.

[0008] As a preferred technical solution, the dispersing component includes two shafts extending into the lower part of the hopper. The two shafts are connected by a gear set outside the lower part of the hopper, and each shaft is provided with multiple dispersing rollers inside the lower part of the hopper.

[0009] As a preferred technical solution, the disintegration component further includes a power motor, which is drivenly connected to one of the shafts.

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

[0011] When the centrifuge feeds crystalline salt, the crystalline salt enters the lower part of the hopper from the upper part and is discharged through the rectangular discharge port at the bottom. As the crystalline salt flows in the lower part of the hopper, its flow direction changes. The set dispersing component disperses the crystalline salt, allowing it to flow smoothly and fall slowly to the next process without bridging or blockage. Attached Figure Description
