Description

Technical Field

[0001] This utility model provides a particle size separation tank, and particularly relates to a vibrating particle size separation tank for surface gangue of a coal flow deposit. Background Technology

[0002] Coal gangue separation equipment is a key piece of equipment in the coal processing industry used to separate coal from gangue. Its main function is to remove gangue from the coal stream through screening and sorting, thereby improving the purity of the coal, reducing the difficulty of subsequent processing, and ensuring the quality of coal products. It is widely used in coal mining, washing and other processes.

[0003] Existing coal flow surface gangue separation devices typically consist of a simple tank structure with an inlet at the top and an outlet at the bottom or side. Internally, fixed screens or grids are often used as separation components, achieving particle size separation through the material's own gravity. The support structure is usually a simple bracket directly connected to the tank. However, these devices have significant shortcomings. The fixed separation gap of the screens or grids makes it difficult to adapt to the separation requirements of gangue of different particle sizes. Furthermore, the lack of an effective material guiding structure allows coal flow to accumulate in the separation area, leading to blockages and low separation efficiency. Additionally, the support structure lacks stability, easily swaying under material impact, affecting separation accuracy. The insufficiently tight fit between the drive and separation components further restricts the improvement of separation performance. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1 and Figure 2 As shown, a vibratory particle size separator for surface gangue in a coal flow accumulation includes an outer shell 1, a separating roller shaft 2 disposed within the outer shell 1, and a support assembly supporting the outer shell 1. The outer shell 1 has a feed inlet 11 at the top and a discharge structure on one side, which consists of opposing first and second side plates, a top plate connected to the top of the side plates, a bottom plate, and side side panels. The feed inlet 11 is located on the top plate, and the discharge structure includes a discharge outlet on the side side panel. The support assembly has two symmetrical support beams. The outer shell 1 is mounted to the support beams via connectors. The support beams have mounting holes at both ends for connecting to an external foundation. The separating roller shaft 2 is rotated via bearings through mounting holes on the first and second side plates of the outer shell 1. The outer shell 1 also has a drive assembly mounting section for mounting a motor or other components to drive the separating roller shaft 2 to rotate.

[0027] In this embodiment, the first side plate and the second side plate of the outer shell 1 are arranged opposite to each other. The top plate, the bottom plate and the side plate are respectively connected to the top, bottom and side of the first side plate and the second side plate to form a closed working space. The feed inlet 11 is opened on the top plate and the discharge outlet is opened on the side plate, forming a material inlet and outlet channel. The two support beams of the support assembly are symmetrically distributed. The outer shell 1 is fixed to the support beams by connectors. The mounting parts at both ends of the support beams are connected to the external foundation by mounting holes to provide stable support for the entire device. The two ends of the separating roller shaft 2 are rotatably engaged with the mounting holes on the first side plate and the second side plate of the outer shell 1 by bearings. The motor and other drive components installed in the drive assembly mounting part can drive the separating roller shaft 2 to rotate.

[0028] From an implementation perspective, this structural design ensures the orderly flow of materials within a closed space. The stable support of the supporting components prevents the device from shaking due to vibration during operation, guaranteeing the stability of the separation operation. The rotational cooperation design between the separation roller 2 and the outer shell 1 enables the separation roller 2 to operate efficiently to achieve material separation. From an innovative perspective, the coordinated cooperation of various components solves the problem of poor stability in existing devices. The closed space formed by the outer shell 1 reduces material splashing, the stable support of the supporting components improves the overall load-bearing capacity of the device, and the cooperation between the separation roller 2 and the drive components provides power guarantee for efficient separation, thereby improving the efficiency and reliability of the separation operation.

[0029] like Figure 3 and Figure 4 As shown, the separating roller shaft 2 consists of a roller shaft body 21, several separating blades 22 sleeved on it, and a limiting member 23 for axial positioning. The separating blades 22 are spaced apart along the axial direction of the roller shaft body 21 to form material separation gaps. They are annular with raised structures for crushing material on their outer periphery. The limiting member 23 is a limiting sleeve that fits onto the roller shaft body 21 and is fixed by fasteners. Inside the outer shell 1, there is a guide plate 13 that cooperates with the separating roller shaft 2. It is inclined, with one end near the feed inlet 11 and the other end near the discharge outlet, and is used to guide the material to move towards the separating roller shaft 2 and assist in separation.

[0030] In this embodiment, a number of separating blades 22 are sleeved on the roller body 21 and distributed at intervals along its axial direction. Adjacent separating blades 22 form a material separation gap. The limiting member 23 is also sleeved on the roller body 21 as a limiting sleeve. It is fixed to the roller body 21 by fasteners, thereby limiting the separating blades 22 axially. The separating blades 22 are annular and have a protruding structure on the outer periphery. The guide plate 13 is located inside the outer shell 1 and is in an inclined state. One end of it is close to the feed port 11 and the other end is close to the discharge port, and it cooperates with the separating roller 2.

[0031] In terms of implementation, the spacing of the separating blades 22 creates a separation gap that can screen gangue of different particle sizes according to requirements. The raised structure can crush the material, and the limiting component 23 ensures the stability of the separating blades 22 during operation. The inclined setting of the guide plate 13 effectively guides the material to move towards the separating roller shaft 2, avoiding material accumulation. From an innovative perspective, this structural combination solves the problems of fixed separation gap, poor adaptability, and easy clogging in existing devices. The design of the separating blades 22 improves the separation accuracy and material handling capacity, while the guide plate 13 improves the separation efficiency, making the entire separation process smoother and more efficient.

[0032] During use, this device requires a motor as a drive component to connect to the drive assembly mounting part to drive the separation roller shaft 2 to rotate. It also requires a conveyor belt to feed the coal flow accumulation from the feed inlet 11. The separated material can be transported out through the discharge outlet by another conveyor belt. The outer shell 1 can be made of wear-resistant cast iron, the separation blades 22 can be made of high manganese steel to enhance wear resistance, the support beam can be made of Q235 steel to ensure support strength, and the bearing can be a deep groove ball bearing to reduce friction when the separation roller shaft 2 rotates.

[0033] Specifically, during installation, the support beam is first fixed to the concrete foundation using expansion bolts through the mounting holes at both ends of the support beam. Then, the outer shell is fastened to the support beam using bolt connectors. The deep groove ball bearing is embedded into the mounting holes of the first and second side plates of the outer shell. The two ends of the separating roller shaft are inserted into the inner ring of the bearing and positioned by the shaft shoulder. Then, the motor output shaft is connected to one end of the separating roller shaft through a coupling, and the motor is fixed to the drive assembly mounting part. During use, the motor is started to drive the separating roller shaft to rotate. The coal flow accumulation is transported from the feed port to the outer shell through the conveyor belt. The material is guided to the separating roller shaft by the guide plate. Under the rotation of the separating blades, the material that meets the particle size falls through the separation gap and is then transported out by another conveyor belt through the discharge port. After the operation is completed, the motor is turned off. The internal components are inspected and maintained periodically through the maintenance door opened on the side plate of the outer shell.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
