Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically a rapid separation device for a flat-plate self-unloading centrifuge. Background Technology

[0002] A centrifuge is a machine that uses centrifugal force to separate the components in a mixture of liquid and solid particles or liquid and liquid. Existing platform centrifuges have a raised conical structure at the bottom of the drum. For reference, see announcement number CN210675541U, which describes a plate centrifuge including a frame, a shell, and a cover. A drum is housed inside the shell, and a filter bag is placed inside the drum. The outer shell is characterized by a jacket with an inlet on the upper left and a outlet at the lower left. The drum includes a plate covered with filter holes, a flange at the top, and a horizontal basket bottom at the bottom. The filter bag includes a filter bag body and a cover.

[0003] The filter bag body and the top cover of the above-mentioned device are connected by a connecting device. The advantages are simple structure, good stability, large loading capacity, convenient and quick loading, and effective prevention of material overflow. However, because the filter bag and the top cover are connected, it is inconvenient to quickly lift the filter bag with hoisting equipment and open the bottom of the filter bag to discharge the filter cake. Utility Model Content

[0004] The purpose of this invention is to provide a rapid separation device for a self-unloading centrifuge with a flat plate top, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rapid separation device for a self-unloading centrifuge with a flat plate includes a flat plate base, a tank body fixedly connected to the upper surface of the flat plate base, a cover body hinged to the upper surface of the tank body, a cylinder hinged to the upper surface of the flat plate base, a motor fixedly connected to the upper surface of the flat plate base, a spline seat fixedly connected to the upper surface of the flat plate base, and a spline shaft rotatably connected inside the spline seat.

[0007] A rotating drum is fixedly connected to the upper end of the spline shaft. A filter mechanism is nested on the outer surface of the rotating drum. The filter mechanism includes a connecting ring, a filter bag, and a mounting ring. The connecting ring is snapped onto the upper surface of the rotating drum. The filter bag is fixedly connected to the inner surface of the connecting ring. The mounting ring is fixedly connected to the lower surface of the filter bag. An inner cover is hinged to the lower surface of the mounting ring.

[0008] Furthermore, the filter mechanism also includes a lifting ring, a sliding pin, a baffle, and a fastening knob. The lifting ring is fixedly connected to the upper surface of the connecting ring, the sliding pin is embedded and slidably connected to the lower surface of the inner cover, a limit block is fixedly connected to the upper surface of the sliding pin, the baffle is fixedly connected to the upper surface of the mounting ring, and the fastening knob is threadedly connected to the lower surface of the sliding pin.

[0009] Furthermore, the output end of the motor is fixedly connected to a first synchronous pulley, and a synchronous belt is meshed with the outer surface of the first synchronous pulley.

[0010] Furthermore, a second synchronous pulley is fixedly connected to the outer surface of the spline shaft, and the first synchronous pulley is connected to the second synchronous pulley via a synchronous belt.

[0011] Furthermore, the upper surface of the drum is provided with a connecting groove, and the lower surface of the connecting ring is fixedly connected with a locking block that matches the groove.

[0012] Furthermore, four buffers are fixedly connected to the lower surface of the flat base.

[0013] Furthermore, the outer surface of the tank is fixedly connected to a liquid outlet pipe, and the outer surface of the tank is fixedly connected to a hinge seat. The cover is hinged to the tank via the hinge seat. The upper surface of the cover is fixedly connected to an observation window, the upper surface of the cover is provided with a liquid inlet pipe, the upper surface of the cover is fixedly connected to a flushing pipe, and the other end of the cylinder is hinged to the cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When quickly opening the inner cover, rotate the fastening knob and manually move the sliding pin outward to separate the upper end of the sliding pin from the baffle. This will quickly remove the inner cover from its limit position, making it easier to open. The limit block and the inner cover are slidably connected to assist in limiting the sliding of the sliding pin. When the baffle rotates with the drum, it can disperse the material entering through the liquid inlet pipe, which helps to improve the separation efficiency.

[0016] 2. Rotate the connecting ring along the inclined surface of the clamping block to separate the connecting groove and the connecting ring. With the help of hoisting equipment, the connecting ring and the filter bag can be quickly lifted to separate the filter bag and the drum. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Please see Figure 1-4 In this embodiment of the utility model, a rapid separation device for a self-unloading centrifuge on a flat plate includes a flat plate base 1, a tank 2 fixedly connected to the upper surface of the flat plate base 1, a cover 3 hinged to the upper surface of the tank 2, a cylinder 4 hinged to the upper surface of the flat plate base 1, a motor 5 fixedly connected to the upper surface of the flat plate base 1, a spline seat 6 fixedly connected to the upper surface of the flat plate base 1, and a spline shaft 601 rotatably connected inside the spline seat 6.

[0024] A rotating drum 7 is fixedly connected to the upper end of the spline shaft 601. A filter mechanism 8 is nested on the outer surface of the rotating drum 7. The filter mechanism 8 includes a connecting ring 801, a filter bag 802, and a mounting ring 804. The connecting ring 801 is snapped onto the upper surface of the rotating drum 7. The filter bag 802 is fixedly connected to the inner surface of the connecting ring 801. The mounting ring 804 is fixedly connected to the lower surface of the filter bag 802. An inner cover 805 is hinged to the lower surface of the mounting ring 804.

[0025] Specifically, during use, the raw material enters the interior of the tank 2. Under the action of centrifugal force, the solid matter is blocked by the filter mechanism 8, and the liquid matter is discharged from the outlet pipe 201. When separating, external hoisting equipment is used. The hook of the hoisting equipment is connected to the connecting ring 801. After hoisting, the connecting ring 801 can be lifted to further separate the filter bag 802 and the drum 7. The inner cover 805 can be opened quickly, which is conducive to the dumping of solid matter.

[0026] Example 1

[0027] like Figure 1-4 As shown, the filter mechanism 8 also includes a lifting ring 803, a sliding pin 806, a baffle 807, and a fastening knob 809. The lifting ring 803 is fixedly connected to the upper surface of the connecting ring 801. The sliding pin 806 is embedded and slidably connected to the lower surface of the inner cover 805. A limit block 808 is fixedly connected to the upper surface of the sliding pin 806. The baffle 807 is fixedly connected to the upper surface of the mounting ring 804. The fastening knob 809 is threadedly connected to the lower surface of the sliding pin 806.

[0028] In this embodiment, the hook is connected to the lifting ring 803 and the connecting ring 801. When the inner cover 805 is opened quickly, the fastening knob 809 is rotated and the sliding pin 806 is moved outward manually at the same time, so that the upper end of the sliding pin 806 is separated from the baffle 807. This allows the inner cover 805 to quickly lose its limiting position, making it easier to open. The limiting block 808 and the inner cover 805 are slidably connected to assist in limiting the sliding of the sliding pin 806. When the baffle 807 rotates with the drum 7, the material entering through the liquid inlet pipe 302 can be dispersed, which helps to improve the separation efficiency.

[0029] Example 2

The outer surface of the spline shaft 601 is fixedly connected to a second synchronous pulley 602, and the first synchronous pulley 501 is connected to the second synchronous pulley 602 through the synchronous belt 502.

[0032] In this embodiment, the motor 5 transmits power through the synchronous belt 502, causing the spline shaft 601 to drive the drum 7 to rotate, thereby achieving solid-liquid separation under the action of centrifugal force.

[0033] like Figure 1-4 As shown, the upper surface of the drum 7 is provided with a connecting groove 701, the lower surface of the connecting ring 801 is fixedly connected with a locking block that matches the groove, the lower surface of the flat base 1 is fixedly connected with four buffers 101, the outer surface of the tank body 2 is fixedly connected with a liquid outlet pipe 201, the outer surface of the tank body 2 is fixedly connected with a hinge seat 202, the cover 3 is hinged to the tank body 2 through the hinge seat 202, the upper surface of the cover 3 is fixedly connected with an observation window 301, the upper surface of the cover 3 is provided with a liquid inlet pipe 302, the upper surface of the cover 3 is fixedly connected with a flushing pipe 303, and the other end of the cylinder 4 is hinged to the cover 3.

[0034] In this embodiment, rotating the connecting ring 801 along the inclined surface of the card block can separate the connecting groove 701 and the connecting ring 801. With the help of the hoisting equipment, the connecting ring 801 and the filter bag 802 can be quickly lifted to separate the filter bag 802 and the drum 7. The flushing pipe 303 can be used to feed liquid and flush the filter cake on the inner wall of the filter bag 802 to increase the filtrate output.
