Description

Technical Field

[0001] This utility model belongs to the field of conveying equipment, and specifically relates to a conveying spiral structure for the filter section of a concentration centrifuge. Background Technology

[0002] The conveying spiral structure in the filtration section of a centrifuge is a core functional component for solid-liquid separation. While current conveying spiral structures in the filtration section of centrifuges can meet basic solid-liquid separation and conveying requirements, they still have limitations when facing complex operating conditions. Existing structural forms are relatively simple and often fail to fully adapt to diverse material characteristics. For example, for materials with large particle sizes, spiral components with uniform pitch and blade shape struggle to simultaneously achieve effective conveying of large particles and fine filtration of small particles. This is because a single structure cannot flexibly adjust its action on particles of different sizes during conveying according to material characteristics. A conventional solution is to adjust the speed difference between the spiral and the drum, but this only alleviates the problem to a limited extent and has significant drawbacks: excessively large speed difference adjustments exacerbate mechanical wear between the spiral blades and the material / drum, significantly shortening the equipment's lifespan; while insufficient adjustments fail to fundamentally improve the processing effect on different particles, making it difficult to improve separation efficiency and quality. Therefore, a new structure is needed to solve these technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a conveying spiral structure for the filtration section of a concentration centrifuge, thereby solving the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a conveying spiral structure for the filtration section of a centrifuge, comprising: a spiral assembly and a housing assembly, wherein the spiral assembly for conveying is installed inside the housing assembly, the spiral assembly includes a rotating shaft for installing a first auger section and a second auger section, the front end of the rotating shaft is equipped with a coupling for connecting to the centrifuge, the housing assembly includes a filter housing for filtration, the outer surface of the filter housing is equipped with a housing body, and the outer surface of the housing assembly is equipped with a discharge cylinder and a liquid discharge cylinder.

[0005] In a preferred embodiment, the rotating shaft is connected to the output shaft of the concentrator centrifuge via a coupling. An auger section one is mounted on the outer surface of the rotating shaft, and an auger section two is mounted on the rear side of the auger section one via the rotating shaft. The auger section one and the auger section two are connected to each other.

[0006] In a preferred embodiment, the length of the first auger section matches the length of the second auger section. Both the first and second auger sections have a spiral structure. The spacing between the first auger sections is greater than the spacing between the second auger sections, and the spacing between the second auger sections gradually decreases. During use, the larger spacing of the first auger sections facilitates the rapid introduction and initial separation of materials, avoids blockage, and improves feeding efficiency. The second auger section adopts a conical structure with a smaller spacing, which gradually squeezes the materials during the conveying process, effectively enhancing the dehydration effect.

[0007] In a preferred embodiment, the second auger section has a conical structure with a gradually decreasing diameter, the outer shell assembly has a conical bullet structure, and a spiral assembly is installed inside the outer shell assembly via a centrifuge. The right end of the outer shell assembly is the inlet of the centrifuge filtration section.

[0008] In a preferred embodiment, the size of the filter housing is smaller than that of the housing body, the filter housing is installed inside the housing body, a receiving cavity is provided between the filter housing and the housing body, and a discharge cylinder is installed on the outer surface of the filter housing.

[0009] In a preferred embodiment, the discharge cylinder is installed on the left edge of the outer surface of the filter housing, and the liquid discharge cylinder is installed on the right edge of the outer surface of the housing body. A solenoid valve is provided at the connection between the liquid discharge cylinder and the housing body. In use, by setting the housing assembly, the spiral assembly is enclosed inside, forming a stable separation space. The filter housing is responsible for intercepting the solid phase and allowing the liquid phase to pass through, thus achieving preliminary solid-liquid separation.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a spiral assembly, the spiral assembly includes a rotating shaft for installing auger section one and auger section two. Both auger section one and auger section two are spiral structures. The distance between auger section one is greater than the distance between auger section two. Auger section two is conical. During use, the large distance between auger section one facilitates the rapid introduction and initial separation of materials, avoids clogging, and improves feeding efficiency. Auger section two adopts a conical structure with a small distance, which gradually squeezes the materials during the conveying process, effectively enhancing the dehydration effect. At the same time, the conical design can make the materials gather towards the center. Combined with the centrifugal force of the centrifuge, it further improves the solid-liquid separation accuracy, taking into account both conveying efficiency and separation quality.

[0011] 2. By setting up an outer shell assembly, a spiral assembly for conveying is installed inside the outer shell assembly. The outer shell assembly includes a filter shell for filtration. The outer surface of the filter shell is fitted with the outer shell body. The outer surface of the outer shell assembly is fitted with a discharge cylinder and a liquid discharge cylinder. In use, by setting up the outer shell assembly, the spiral assembly is enclosed inside, which can form a stable separation space. The filter shell is responsible for intercepting the solid phase and allowing the liquid phase to pass through, thereby achieving preliminary solid-liquid separation. Attached Figure Description

[0018] 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.

[0019] Please see Figures 1 to 3As the first embodiment of this utility model: a conveying spiral structure for the filter section in a centrifuge, comprising: a spiral assembly and a shell assembly, wherein the spiral assembly for conveying is installed inside the shell assembly, the spiral assembly includes a rotating shaft 100 for mounting a first auger section 120 and a second auger section 130, the front end of the rotating shaft 100 is fitted with a coupling 110 for connecting with the centrifuge, the shell assembly includes a filter shell 220 for filtering, a shell body 200 is mounted on the outer surface of the filter shell 220, and a discharge cylinder 230 and a liquid discharge cylinder 240 are mounted on the outer surface of the shell assembly;

[0020] The rotating shaft 100 is connected to the output shaft of the concentrator centrifuge via the coupling 110. A screw conveyor section 120 is installed on the outer surface of the rotating shaft 100. A screw conveyor section 2 130 is installed on the rear side of the screw conveyor section 120 via the rotating shaft 100. The screw conveyor section 120 and the screw conveyor section 2 130 are connected to each other.

[0021] The length of auger section 120 is matched with the length of auger section 230. Both auger section 120 and auger section 230 are spiral structures. The spacing between auger section 120 is greater than the spacing between auger section 230, and the spacing between auger section 230 gradually decreases.

[0022] The second auger section 130 has a conical structure, and the diameter of the second auger section 130 gradually decreases. The outer shell assembly has a conical bullet structure. Inside the outer shell assembly, a spiral assembly is installed through the rotation of the concentrator centrifuge. The right end of the outer shell assembly is the inlet of the filter section of the concentrator centrifuge.

[0023] During use, the user can install the device in the filtration section of a centrifuge (the specific installation process, principle, and structure need to be selected by the user according to the actual situation, and will not be elaborated here). When the screw assembly is in use, its rotating shaft 100 will rotate through the centrifuge, thereby driving the auger section 120 and auger section 130 on the outer surface of the rotating shaft 100 to rotate. Since the distance between auger section 120 is greater than the distance between auger section 130, and the distance between auger section 130 gradually decreases, and auger section 130 has a conical structure, when the screw assembly is performing a conveying task, at this time... The material first enters through the outer casing assembly from the direction of auger section 120, then is conveyed by auger section 120, and then conveyed to auger section 230, and finally discharged from the discharge cylinder 230 inside the outer casing assembly. Because the auger section 120 has a large spacing during use, it is conducive to the rapid introduction and initial separation of materials, avoiding blockage and improving feeding efficiency. Auger section 230 adopts a conical structure with a small spacing, which gradually squeezes the material during the conveying process, effectively enhancing the dehydration effect. At the same time, the conical design can make the material gather towards the center, which, together with the centrifugal force of the centrifuge, further improves the solid-liquid separation accuracy, taking into account both conveying efficiency and separation quality.

[0024] Please see Figures 1 to 3 As a second embodiment of the present invention: based on the description in the above embodiments, the size of the filter housing 220 is smaller than that of the housing body 200. The filter housing 220 is installed inside the housing body 200. A receiving cavity 210 is provided between the filter housing 220 and the housing body 200. A discharge cylinder 230 is installed on the outer surface of the filter housing 220.

[0025] The discharge cylinder 230 is installed on the left edge of the outer surface of the filter housing 220, and the liquid discharge cylinder 240 is installed on the right edge of the outer surface of the housing body 200. A solenoid valve is provided at the connection between the liquid discharge cylinder 240 and the housing body 200.

[0026] When in use, if the material is conveyed by the spiral assembly according to the operation steps of the first embodiment, the spiral assembly will centrifugally convey the material and then allow the liquid material to enter the receiving cavity 210 between the outer shell 200 and the filter shell 220 (the filter shell 220 is a one-way filter shell 220, the specific structure and working principle of which will not be described in detail here, its purpose is to prevent the liquid from flowing back into the filter shell 220 after being thrown out). After the liquid is stored in the receiving cavity 210, the user can discharge the liquid through the liquid outlet 240 on the outer surface of the outer shell 200. Since the spiral assembly is enclosed inside by the outer shell assembly during use, a stable separation space can be formed. The filter shell 220 is responsible for intercepting the solid phase and allowing the liquid phase to pass through, thus achieving preliminary solid-liquid separation.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
