Description

Technical Field

[0001] This utility model relates to the technical field of horizontal centrifuge equipment, and in particular to an improved horizontal centrifuge device. Background Technology

[0002] A horizontal centrifuge is an industrial device used for solid-liquid separation. Its core components include a high-speed conical drum, a screw conveyor rotating in the same direction as the drum but at a slightly lower speed, and a differential. When sludge is fed into the drum through a hollow shaft, the centrifugal force generated by the high-speed rotation causes the solid particles in the sludge to adhere to the inner wall of the drum, forming a solid ring layer. Water, due to its lower density and weaker centrifugal force, forms a liquid ring layer inside the solid ring layer. Utilizing the speed difference between the screw and the drum—that is, relative motion—the sludge in the solid ring layer is slowly pushed away. The liquid in the liquid ring layer is continuously discharged through the weir by gravity at the cone end of the drum, forming the separated liquid. During the waste separation process, the waste is crushed and then enters the horizontal centrifuge. The separated solid waste is thrown out from the outlet. The solid waste is first thrown onto the centrifuge's protective cover, and then slides down the cover into the discharge port for discharge. Because the separated solid waste is highly viscous and falls slowly, it is prone to clogging. It is necessary to open the protective cover to clean the blockage, which affects the normal operation of the centrifuge. Utility Model Content

[0003] The purpose of this invention is to provide an improved horizontal centrifuge device to solve the technical problem that solid materials in existing horizontal centrifuges are prone to clogging.

[0004] The utility model relates to an improved horizontal centrifuge device, comprising a body, a conical drum disposed within the body, a plurality of discharge ports partially formed along the circumferential direction on the conical drum, a protective cover mounted on the body, a vibrating plate matching the shape of the protective cover disposed on the inner wall of the protective cover, the vibrating plate being connected to a vibration assembly, the vibration assembly being connected to a drive assembly, and the drive assembly driving the vibration assembly to vibrate up and down.

[0005] Furthermore, the vibration assembly includes a square column, the bottom end of which is connected to the vibration plate. A square hole is provided on the protective cover, and the square column is slidably connected to the square hole. A limiting plate is connected to the top of the square column, and a compression spring is fitted on the square column. The top and bottom ends of the compression spring are in contact with the limiting plate and the machine body, respectively.

[0006] Furthermore, the drive assembly includes a camshaft rotatably connected to a frame, the frame being fixedly mounted on the cover, the camshaft being drive-connected to a motor, and the cam of the camshaft contacting the limiting plate.

[0007] Furthermore, the vibrating plate is semi-circular, and guide plates are inclined inward at both ends of the vibrating plate.

[0008] Furthermore, the angle between the guide plate and the vertical direction is 10° to 15°.

[0009] Furthermore, baffles are installed on both sides of the vibrating plate and the guide plate.

[0010] Furthermore, one end of the protective cover is hinged to the machine body, and the other end of the protective cover is fixedly connected to the machine body by bolts.

[0011] The beneficial effects of this utility model are as follows: This utility model has a simple structure. A vibrating plate vibration assembly is designed on the protective cover of the horizontal centrifuge, so that solid waste is thrown onto the vibrating plate for discharge. Due to the high-frequency vibration of the vibrating plate, the solid waste adhering to the vibrating plate can be quickly shaken off, ensuring that the solid waste is discharged quickly and smoothly, preventing the centrifuge from clogging. It is worth promoting and using on a large scale. Attached Figure Description

Detailed Implementation

[0016] like Figures 1 to 3 As shown, an improved horizontal centrifuge device includes a body 1, a conical drum 2 disposed inside the body 1, a plurality of discharge outlets 3 partially formed along the circumferential direction on the conical drum 2, a protective cover 4 mounted on the body 1, one end of the protective cover 4 being hinged to the body 1, and the other end of the protective cover 4 being fixedly connected to the body 1 by bolts, a vibrating plate 5 matching the shape of the protective cover 4 being disposed on the inner wall of the protective cover 4, the vibrating plate 5 being connected to a vibration assembly, the vibration assembly being driven by a drive assembly, and the drive assembly driving the vibration assembly to vibrate up and down.

[0017] Specifically, such as Figure 2 and Figure 3As shown, the vibration assembly includes a square column 8, the bottom end of which is connected to the vibration plate 5. A square hole is provided on the protective cover 4, and the square column 8 is slidably connected to the square hole. A limit plate 10 is connected to the top of the square column 8, and a compression spring 9 is fitted on the square column 8. The top and bottom ends of the compression spring 9 are in contact with the limit plate 10 and the machine body 1, respectively. The drive assembly includes a camshaft 11, which is rotatably connected to the frame 13. The frame 13 is fixedly installed on the protective cover 4. The camshaft 11 is connected to the motor 12 for transmission. The cam of the camshaft 11 is in contact with the limiting plate 10. The vibrating plate 5 is a semi-circular arc shape that matches the shape of the protective cover 4. In order to better guide the separated solid phase to be smoothly discharged into the discharge port 14, guide plates 6 are connected to both ends of the vibrating plate 5 at an inward angle. The angle between the guide plates 6 and the vertical direction is 12°. Baffles are installed on both sides of the vibrating plate 5 and the guide plates 6 to effectively prevent the solid phase from splashing when it is thrown out.

[0018] In practical use, the horizontal centrifuge separates the solid and liquid phases of the waste through the differential rotation of the conical drum 2 and the auger set inside the conical drum 2 (existing technology, not described in detail). The separated solid phase of the waste is thrown out from the outlet 3, and a portion of it is thrown onto the vibrating plate 5. The motor 12 is started, and the motor 12 drives the camshaft 11 to rotate at high speed, thereby driving the limit plate 10, the square column 8, and the vibrating plate 5 to vibrate up and down at high frequency, thereby quickly shaking off the solid waste adhering to the vibrating plate 5, ensuring that it falls smoothly into the discharge port 14 and preventing blockage.

[0019] The above are merely preferred embodiments of the present utility model and are 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 shall be included within the protection scope of the present utility model.
