Technical Field
[0001] This utility model relates to the field of pusher centrifuge technology, specifically to a feeding trough structure for a double-push double-outlet pusher centrifuge. Background Technology
[0002] A centrifuge is a machine that uses centrifugal force to separate the components of a mixture of liquids and solid particles or liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions; or to separate two immiscible liquids with different densities in emulsions.
[0003] Chinese Patent Application No. 202121781704.9 discloses a piston bidirectional pusher centrifuge, including a piston rotating rod that performs horizontal linear motion and rotational motion. An inner sleeve is provided between the piston rotating rod and a bearing seat. The bearing seat is located inside an outer shell. A rotating drum is provided on the side of the bearing seat. A screen is provided inside the rotating drum. A pusher is provided inside the screen. A through hole is provided on the pusher near the screen. The outer wall of the pusher is in contact with the inner surface of the screen. The pusher performs repeated linear motion along the axial direction inside the screen. The pusher is connected to the side of the piston rotating rod through a connector. A feeding hopper is provided on the side of the pusher away from the piston rotating rod. A discharge port is provided on the side of the screen and on the rotating drum. An outer cylinder is provided on the side of the outer shell. A scraper is provided inside the outer cylinder near the discharge port.
[0004] However, after the material flows out of the discharge port, it is blocked by the scraper blade, which causes the material to stick to the scraper blade, also known as the feeding trough.
[0005] Therefore, the applicant has developed a new technical solution in the actual production process to solve the above-mentioned technical problems. Utility Model Content
[0006] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a feeding trough structure for a double-push, double-outlet type centrifuge, which has the advantage of reducing material adhesion to the inner wall of the feeding trough.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0008] This utility model provides a feeding trough structure for a double-push double-discharge type centrifuge, including a surrounding plate connected to the centrifuge product chamber via a connector. The surrounding plate is a semi-circular arc plate distributed coaxially with the drum. Vertical plates are provided at both ends of the surrounding plate. There is a gap between the surrounding plate and the outer wall of the drum, and they are distributed directly opposite the discharge port on the drum. An anti-adhesion lining layer is provided on the side of the surrounding plate and the vertical plate facing the outer wall of the drum.
[0009] By adopting the above technical solution, the surrounding plate and vertical plate are located on the outer wall of the drum, which plays a role in guiding and blocking the material flowing out from the discharge port. The anti-adhesion liner is set on the inner wall of the surrounding plate and vertical plate, that is, on the side in contact with the material. At this time, the anti-adhesion liner reduces the material from adhering to the surrounding plate and vertical plate, thus reducing the occurrence of material blockage.
[0010] Preferably, the connector includes an arc-shaped plate located on one side of the enclosure and distributed along the edge of the enclosure. The surface of the arc-shaped plate is perpendicular to the surface of the enclosure. The two ends of the arc-shaped plate extend out of the outer wall and inner wall of the enclosure, respectively. The arc-shaped plate is provided with a plurality of connecting screws on the surface extending out of the outer wall of the enclosure. The inner wall of the centrifuge product chamber is provided with an extension plate extending in the direction of the drum. Each of the connecting screws passes through the arc-shaped plate and is threadedly connected to the extension plate.
[0011] Preferably, the anti-adhesion liner is a PTFE anti-adhesion layer or a PP anti-adhesion layer.
[0012] Preferably, the anti-adhesion liner is detachably connected to the vertical plate or the surrounding plate.
[0013] Preferably, the anti-adhesion liner has a plurality of protrusions inserted into the surrounding panel at intervals on the side connected to the surrounding panel.
[0014] Preferably, the anti-adhesion liner is installed on the vertical plate and the surrounding plate by countersunk screws.
[0015] Preferably, the width of the enclosure is smaller than the length of the entire discharge port, but greater than two-thirds of the length of the discharge port.
[0016] The beneficial effects of this utility model are as follows: the surrounding plate and the vertical plate are located on the outer wall of the drum, which guides and blocks the material flowing out from the discharge port. The anti-adhesion liner is set on the inner wall of the surrounding plate and the vertical plate, that is, on the side in contact with the material. At this time, the anti-adhesion liner reduces the material from adhering to the surrounding plate and the vertical plate, thus reducing the occurrence of material blockage.

[0024] 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.
[0025] A feeding trough structure for a double-push, double-discharge centrifuge, such as... Figure 1 and Figure 2 The centrifuge includes a surrounding plate 1 connected to the centrifuge product chamber via a connector. The surrounding plate 1 is a semi-circular arc plate coaxially distributed with the rotating drum 2. Vertical plates 11 are provided at both ends of the surrounding plate 1. There are gaps between the surrounding plate 1 and the vertical plates 11 and the outer wall of the rotating drum 2, and they are distributed directly opposite the discharge port 3 on the rotating drum 2. The surrounding plate 1 and the vertical plates 11 are provided with an anti-adhesion lining layer 12 on the side facing the outer wall of the rotating drum 2. The centrifuge product chamber corresponds to the outer cylinder of a piston bidirectional push centrifuge disclosed in Chinese Patent Application No. 202121781704.9.
[0026] like Figure 1 and Figure 2 The enclosure 1 and vertical plate 11 are located on the outer wall of the drum 2, which guides and blocks the material flowing out from the discharge port 3. The anti-adhesion liner 12 is set on the inner wall of the enclosure 1 and vertical plate 11, that is, on the side in contact with the material. At this time, the anti-adhesion liner 12 reduces the material adhering to the enclosure 1 and vertical plate 11, reducing the occurrence of material blockage. The lower ends of the two vertical plates 11 extend below the drum 2. The two vertical plates 11 make the lower half of the enclosure 1 an open structure, reducing material accumulation.
[0027] like Figure 1 and Figure 2 and Figure 3The connecting component includes an arc-shaped plate 13 located on one side of the enclosure 1 and distributed along the edge of the enclosure 1. The surface of the arc-shaped plate 13 is perpendicular to the surface of the enclosure 1. The two ends of the surface of the arc-shaped plate 13 extend out of the outer wall and inner wall of the enclosure 1, respectively, which facilitates welding the enclosure 1 to the surface of the arc-shaped plate 13. The inner wall of the arc-shaped plate 13 is distributed close to the outer wall of the drum 2, which facilitates the obstruction of materials. Several connecting screws 131 are provided on the surface of the arc-shaped plate 13 that extends out of the outer wall of the enclosure 1. The inner wall of the centrifuge product chamber is provided with an extension plate 14 extending towards the drum 2. Each connecting screw 131 passes through the arc-shaped plate 13 and is threadedly connected to the extension plate 14. The extension plate 14 facilitates fixing the enclosure 1 and the vertical plate 11 to the outer wall of the drum 2. At this time, there is a gap between the arc-shaped plate 13 and the extension plate 14 and the outer wall of the drum 2, which facilitates the rotation of the drum 2.
[0028] The anti-adhesion liner 12 is a PTFE anti-adhesion layer or a PP anti-adhesion layer.
[0029] The anti-adhesion liner 12 is detachably connected to the vertical plate 11 or the surrounding plate 1. This facilitates the installation and replacement of the anti-adhesion liner 12.
[0030] like Figure 4 The anti-adhesion liner 12 has several protrusions 15 at intervals on the side connected to the surrounding plate 1, which are inserted into the surrounding plate 1. The anti-adhesion liner is installed on the vertical plate 11 and the surrounding plate 1 by countersunk screws. The protrusions 15 facilitate the fit between the anti-adhesion liner 12 and the surrounding plate 1, thereby facilitating the installation of the countersunk screws. The countersunk screws pass through one end of the anti-adhesion liner 12 and enter the surrounding plate 1 or the vertical plate 11. At this time, the nuts of the countersunk screws are embedded in the anti-adhesion liner 12.
[0031] like Figure 3 The length of the discharge hole is distributed along the length of the drum 2. The width of the enclosure 1 is smaller than the length of the entire discharge port 3, but larger than two-thirds of the length of the discharge port 3. The purpose of this design is to block the material in the discharge port 3 on the one hand, and to reduce the accumulation of material between the enclosure 1 and the drum 2 on the other hand, thereby reducing the risk of material blockage.
[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
