Description

Technical Field

[0001] This utility model belongs to the field of physical separation technology, specifically relating to a leak-proof centrifuge with top suspension and bottom unloading. Background Technology

[0002] The discharge port of the top-suspended, bottom-discharge centrifuge is located at the bottom of the support, and the bottom of the drum is also equipped with a discharge port that is opposite to the discharge port. After the filter cake inside the drum is crushed, it is directly discharged through the discharge port and the discharge outlet, making discharge very convenient.

[0003] In some operating conditions, users will install a conveyor belt below the discharge port to allow the filter cake discharged from the centrifuge to be directly transported to the target location via the conveyor belt, thereby further improving the automation of filter cake transfer and collection.

[0004] However, when a centrifuge separates materials that easily produce mist-like gas and form droplets, the droplets, suspended in the drum and not subject to centrifugal force, will flow directly from the lower discharge port and drip onto the conveyor belt below, affecting the conveying of materials in the next process and also impacting the work environment.

[0005] Therefore, it is necessary to provide countermeasures to address this technical problem. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a leak-proof top-suspended bottom-discharge centrifuge, which solves the technical problem that in the top-suspended bottom-discharge centrifuge, some liquid material atomizes and condenses into droplets after escaping the centrifugal force during the centrifugation process and leaks directly from the discharge port, contaminating the conveyor belt below the discharge port.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a leak-proof, top-suspended, bottom-discharge centrifuge, including a base, an outer shell fixedly connected to the base, a centrifugal drive fixedly connected to the top plate of the outer shell, a rotating shaft connected to the centrifugal drive and inserted into the outer shell, a rotating drum fixedly connected to the end of the rotating shaft and located inside the outer shell, a scraper mechanism connected to the top plate of the outer shell and extending into the rotating drum at one end, and a feed pipe connected to the top plate of the outer shell and extending into the rotating drum at one end. The bottom of the rotating drum is provided with a discharge port, and the base is provided with a discharge port directly opposite the discharge port. The discharge port is located within the range of the discharge port. A liquid support plate is horizontally slidably connected below the base. A translation drive is provided on the base to drive the liquid support plate to move horizontally back and forth. The outer diameter of the liquid support plate is larger than the discharge port. The liquid support plate and the discharge port are directly opposite each other. The translation drive drives the liquid support plate to move away from the discharge port or directly below the discharge port.

[0008] As a preferred embodiment, a lead screw is installed below the base on both sides of the discharge port. The two lead screws are parallel to each other, and a lead screw nut is connected to each of the two lead screws. The two sides of the liquid support plate are fixedly connected to the two lead screw nuts respectively. The two ends of the two lead screws are connected to the bottom surface of the base through connecting seats. The two ends of the lead screws are rotatably connected to the connecting seats. The translation drive is a geared motor. There are two translation drives, which are connected to the two lead screws one-to-one. The two translation drives drive the two lead screws to rotate synchronously, which drives the lead screw nuts and the liquid support plate to move along the axial direction of the lead screws.

[0009] As a preferred embodiment, the bottom surface of the liquid tray is cone-shaped, and a downward-extending guide tube is connected to the center of the liquid tray. The guide tube is connected to the liquid storage container through a flexible tube.

[0010] As a preferred embodiment, each of the two lead screws is provided with a guide rail fixedly connected to the bottom surface of the base. The guide rail is parallel to the lead screw. Each side of the liquid support plate is fixedly connected with a slider that slides in cooperation with the guide rail. The slider is supported by the guide rail and slides back and forth along the guide rail under the drive of the lead screw nut.

[0011] As a preferred embodiment, a conveyor belt is provided below the liquid tray.

[0012] As a preferred option, the conveyor belt's conveying direction is consistent with the liquid tray's moving direction.

[0013] The beneficial effects of this utility model are as follows: By setting a sliding liquid tray, when the centrifuge is centrifuging the material, the liquid tray is driven to the bottom of the discharge port to collect the leaking liquid droplets, effectively avoiding the problem of liquid droplets falling onto the conveyor belt below the discharge port and causing pollution. This realizes the anti-leakage function of the top-suspended and bottom-discharge centrifuge. When the centrifuge is unloading, the liquid tray is driven away from the discharge port without affecting the normal unloading of the centrifuge. Attached Figure Description

[0015] The specific implementation scheme of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] like Figure 1 The centrifuge shown is a leak-proof, top-suspended, bottom-discharge centrifuge, comprising a base 1, an outer shell 2 fixedly connected to the base 1, a centrifugal drive 3 fixedly connected to the top plate of the outer shell 2, a rotating shaft 4 driven by the centrifugal drive 3 and inserted into the outer shell 2, a rotating drum 5 fixedly connected to the end of the rotating shaft 4 and located inside the outer shell 2, a scraper mechanism 6 connected to the top plate of the outer shell 2 with one end extending into the rotating drum 5, and a feed pipe 7 connected to the top plate of the outer shell 2 with one end extending into the rotating drum 5. The bottom of the drum 5 is provided with a discharge port 8, and the base 1 is provided with a discharge port 9 that is directly opposite to the discharge port 8. The discharge port 8 is located within the range of the discharge port 9. A liquid support plate 10 is horizontally slidably connected below the base 1. A translation driver 11 is provided on the base 1 to drive the liquid support plate 10 to move horizontally back and forth. The outer diameter of the liquid support plate 10 is larger than that of the discharge port 9. The liquid support plate 10 and the discharge port 9 are directly opposite each other. The translation driver 11 drives the liquid support plate 10 to move away from the discharge port 9 or to move directly below the discharge port 9.

[0017] like Figure 2 As shown, a lead screw 12 is respectively installed below the base 1 on both sides of the discharge port 9. The two lead screws 12 are parallel to each other, and a nut 13 is connected to each of the two lead screws 12. The two sides of the liquid support plate 10 are fixedly connected to the two nuts 13 respectively. The two ends of the two lead screws 12 are respectively connected to the bottom surface of the base 1 through connecting seats 14. The two ends of the lead screws 12 are rotatably connected to the connecting seats 14. Figure 3 As shown, the translation driver 11 is a geared motor. There are two translation drivers 11, which are connected to the two lead screws 12 in a one-to-one transmission. The two translation drivers 11 drive the two lead screws 12 to rotate synchronously, thereby driving the lead screw nut 13 and the liquid support plate 10 to move along the axial direction of the lead screw 12.

[0018] like Figure 1 As shown, the bottom surface of the liquid receiving tray 10 is cone-shaped, and a downward-extending guide tube 15 is connected to the center of the liquid receiving tray 10. The guide tube 15 is connected to the liquid storage container 17 through a flexible tube 16. The droplets received by the liquid receiving tray 10 are directly guided to the liquid storage container 17 for storage through the guide tube 15 and the flexible tube 16, so as not to reduce the load on the base 1.

[0019] like Figure 2 and Figure 3 As shown, each of the two lead screws 12 has a guide rail 18 fixedly connected to the bottom surface of the base 1 on its outer side. The guide rail 18 is parallel to the lead screw 12. Each of the liquid support plate 10 has a slider 19 fixedly connected to its side, which slides in cooperation with the guide rail 18. The slider 19 is supported by the guide rail 18 and slides back and forth along the guide rail 18 under the drive of the lead screw nut 13.

[0020] like Figure 1 As shown, a conveyor belt 20 is installed below the liquid tray 10. The conveyor belt 20 is located directly below the discharge port 9. When the centrifuge needs to discharge, the liquid tray 10 is moved away from the discharge port 9, and the material is discharged directly from the discharge port 9 onto the conveyor belt 20. The conveyor belt 20 transports the material to the designated target location.

[0021] In this embodiment, the conveying direction of the conveyor belt 20 and the moving direction of the liquid tray 10 are preferably set to be the same to reduce the floor space of the centrifuge.

[0022] The working process of this utility model is as follows: Figures 1-3 As shown, during centrifugation, the translation driver 11 drives the liquid tray 10 to move directly below the discharge port 9 (as shown). Figure 3 The solid line indicates the position of the liquid collection tray 10. This tray collects droplets falling from the discharge port 9. When the centrifuge needs to discharge, the translation driver 11 moves the liquid collection tray 10 to one side of the discharge port 9, completely offsetting the liquid collection tray 10 from the discharge port 9 (e.g., ...). Figure 3 (The dashed line indicates the location of the liquid tray 10).

[0023] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
