Description

Technical Field

[0001] The utility model relates to the technical field of horizontal spiral decanter centrifuges, in particular to a horizontal spiral decanter centrifuge which can prevent clogging. Background Art

[0002] Horizontal spiral sedimentation centrifuge is a machine that feeds mud and water mixture into the drum through the feed pipe and spiral discharge port. Under the centrifugal force generated by the high-speed rotation of the main machine, solid particles with larger specific gravity are deposited on the inner wall of the drum. The spiral blades that move relative to the drum continuously scrape the solid particles deposited on the inner wall of the drum and push them out of the discharge port. The separated clear liquid flows out of the drum through the weir plate opening.

[0003] When the horizontal spiral decanter centrifuges currently on the market are in use, the slag is discharged directly through the slag discharge pipe. After long-term use, the inner wall of the slag discharge pipe of the existing horizontal spiral decanter centrifuge is easily adhered to by some slag. As the amount of adhered slag increases, the horizontal spiral decanter centrifuge is easily blocked. Therefore, we propose a horizontal spiral decanter centrifuge that can prevent blocking.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the anti-clogging horizontal spiral decanter centrifuge drives the connecting frame to move downward synchronously through the mutual cooperation of the threaded rod and the movable plate, and the connecting frame promptly cleans the slag material adhered to the inner wall of the slag discharge pipe during the downward movement, so that the horizontal spiral decanter centrifuge has an anti-clogging structure, and the contact area between the horizontal spiral decanter centrifuge and the ground is increased by the connecting seat and the abutment plate, so that the placement of the horizontal spiral decanter centrifuge is more stable.

[0014] 1. The anti-clogging horizontal spiral decanter centrifuge starts the motor to drive the threaded rod connected to the output end to rotate synchronously. As the threaded rod rotates, the movable plate drives the connected connecting frame to move downward simultaneously along the installation groove and the movable cavity. When the connecting frame moves downward, it can scrape and clean the impurities adhering to the inner wall of the slag discharge pipe. The shielding plate blocks the outside of the installation groove to prevent the slag from entering the interior of the movable cavity. The threaded rod and the movable plate cooperate with each other to drive the connecting frame to move downward synchronously. During the downward movement, the connecting frame cleans the slag adhering to the inner wall of the slag discharge pipe in a timely manner, thereby making the horizontal spiral decanter centrifuge have an anti-clogging structure.

[0015] 2. The anti-clogging horizontal spiral decanter centrifuge drives the connected connecting rod to rotate synchronously by turning the knob. As the connecting rod rotates, the connecting seat and the abutment plate provided on the outside can be moved downward synchronously until the abutment plate contacts the placement position, and the rotation of the knob can be stopped. The connecting seat and the abutment plate provided under the centrifuge housing increase the contact area between the horizontal spiral decanter centrifuge and the ground, thereby making the placement of the horizontal spiral decanter centrifuge more stable.

The screw conveyor 2 is installed inside the centrifuge housing 1, and a material distribution port 3 is opened on the surface of the screw conveyor 2. A feed port 4 is provided at one end of the centrifuge housing 1, and a drive motor 5 is installed at the other end of the centrifuge housing 1. A liquid discharge pipe 6 and a slag discharge pipe 7 are respectively provided on both sides of the lower side of the centrifuge housing 1, and a support column 10 is welded to the bottom of the centrifuge housing 1.

[0023] A scraping assembly 8 is provided on the inner side of the slag discharge pipe 7, and the scraping assembly 8 includes a mounting groove 801, a movable cavity 802, a limiting groove 803, a movable plate 804, a connecting frame 805, a limiting block 806, a threaded rod 807, a motor 808 and a shielding plate 809. The mounting groove 801 is provided in the middle of one side of the slag discharge pipe 7, and a movable cavity 802 is provided inside the centrifuge housing 1 on the side close to the mounting groove 801; a limiting groove 803 is provided on the inner wall of the movable cavity 802, and a movable plate 804 is provided inside the movable cavity 802, and one end of the movable plate 804 passes through the interior of the mounting groove 801; a connecting frame 805 is provided inside the slag discharge pipe 7, and the bottom edge of the connecting frame 805 is connected to the movable The top of the plate 804 is connected, and the two sides of the movable plate 804 are connected to the limiting blocks 806, and the limiting blocks 806 are docked in the inside of the limiting groove 803. A threaded rod 807 runs through the middle of the movable plate 804; the threaded rod 807 is connected to the inner wall of the movable cavity 802 through the bearing seat, and a motor 808 is installed on the lower surface of the centrifuge housing 1, and the output end of the motor 808 is connected to the threaded rod 807. The inner wall of the mounting groove 801 is provided with a baffle 809 connected to the movable plate 804, and the limiting blocks 806 are slidably connected to the limiting groove 803. The outer wall of the connecting frame 805 fits the inner wall of the slag discharge pipe 7, and the movable plate 804 and the threaded rod 807 are threadedly connected.

[0024] During the specific implementation, the motor 808 is started to drive the threaded rod 807 connected to the output end to rotate synchronously. Since the movable plate 804 and the threaded rod 807 are threadedly connected, the movable plate 804 can drive the connected connecting frame 805 to move downward simultaneously along the installation groove 801 and the movable cavity 802 as the threaded rod 807 rotates.

[0026] During specific implementation, turning the knob 16 drives the connected connecting rod 15 to rotate synchronously. Since the connecting rod 15 and the connecting seat 12 are threadedly connected, the connecting seat 12 arranged on the outside can be moved downward as the connecting rod 15 rotates. The downward-moving connecting seat 12 moves steadily downward along the guide rod 14 while driving the connected abutment plate 13 to move downward synchronously until the abutment plate 13 contacts the placement position. The rotation of the knob 16 can be stopped. By providing the connecting seat 12 and the abutment plate 13 below the centrifuge housing 1, the contact area between the horizontal spiral sedimentation centrifuge and the ground is increased, thereby making the placement of the horizontal spiral sedimentation centrifuge more stable.
