Description

Technical Field

[0001] The utility model belongs to the technical field of feed screening, and in particular relates to a multi-stage screening device for protein feed. Background Art

[0002] Amino acids have a wide range of uses and can be used in the food and feed industries. The amino acids produced are extracted from proteins. During the production process of protein feed, they need to be screened to ensure the quality of the finished product.

[0003] The discharge pipe structure of the existing multi-stage screening device is simple. When the staff finds that the discharged feed obviously does not meet the screening requirements, they cannot stop the discharge immediately. They can only close the screening device and wait for all the feed that has entered the discharge pipe to be discharged before processing. Once there is a lot of feed inside the screening device, it will bring great complexity to the subsequent processing of unqualified feed. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-stage screening device for protein feed, comprising a screening bin, which is provided with at least two layers, and the multiple layers of screening bins are stacked; a discharge pipe, which is arranged on the side of each of the screening bins and is connected to the interior of the screening bin; it also includes a blocking assembly, which is composed of an adjusting member and a closing member, wherein the adjusting member is slidably arranged at the outlet position of the discharge pipe, and the closing member is arranged inside the discharge pipe, and the adjusting member is connected to the closing member; a connecting shaft passing through the axis of the discharge pipe is fixed inside, and the closing member includes two closing plates rotatably connected to the connecting shaft at one end, and one end of the closing plate rotates around the axis of the connecting shaft, and the other end of the closing plate is equipped with a pull rope, which passes through the discharge pipe and is connected to the adjusting member.

[0006] Preferably, the adjusting member comprises a sleeve movably mounted on the discharge pipe, a first adjusting groove for a pull rope to pass through is formed on the surface of the discharge pipe, and the pull rope is fixedly connected to the inner wall of the sleeve.

[0007] Preferably, a rubber block is bonded to the discharge pipe, and the rubber block abuts against the top inner wall of the sleeve, that is, when the sleeve moves upward and drives the closing plate to achieve sealing, the rubber block can be forced to deform by abutting against the rubber block, thereby completing the limiting in a manner of increasing friction.

[0008] Preferably, a baffle is fixed on the discharge pipe, and the baffle is in contact with the top end surface of the sleeve. When the two are in contact, the closing plate is in a horizontal state, thereby sealing the inside of the discharge pipe. The baffle is located on the top of the rubber block.

[0009] Preferably, the sleeve is provided with a second adjustment groove extending to its bottom end surface on both sides, and limiting protrusions are installed on both sides of the bottom of the discharge pipe, and the limiting protrusions are connected with the second adjustment grooves. When the sleeve moves downward, once the limiting protrusions abut against the inner top end surface of the second adjustment groove, the sleeve will not continue to descend to avoid falling directly, and at the same time the closing plate tends to be vertical, that is, the inside of the discharge pipe is in an open state, and normal discharge can be carried out.

[0010] Preferably, a thread is provided at the end of the limiting protrusion, and a screw hole for the limiting protrusion to be screwed into is provided on the discharge pipe. The detachable setting of the limiting protrusion can facilitate the installation of the early sleeve and the disassembly of the later sleeve.

[0011] Preferably, it also includes a base, on the top surface of which a spring is installed at an equal angle, the spring is connected to the screening bin at the bottom, and the screening bin at the top is provided with a feed port for feeding.

[0013] The designed blocking component can block the outlet position of the discharge pipe in real time according to processing requirements to prevent the internal feed from continuing to be discharged. It is widely used in temporary maintenance, inspection, and feed screening detection, which improves the functionality of existing screening devices. At the same time, the blocking component has a simple structure, is easy to process and produce, and has high practicality as a whole. BRIEF DESCRIPTION OF THE DRAWINGS
