[0002] Decanter centrifuges are a vital piece of equipment widely used in industrial solid-liquid separation, particularly in the chemical, pharmaceutical, food, and environmental protection industries. Decanter centrifuges use the centrifugal force generated by high-speed rotation to separate substances of varying densities. One of the key factors in achieving this separation is controlling the centrifugal level.

[0003] Traditional mechanical adjustment devices have complex structures and require many manual operation steps during the adjustment process, which not only increases the workload of operators but also reduces production efficiency. Especially in working conditions where frequent liquid level adjustments are required, the complex operation process is particularly inconvenient, which seriously restricts the efficiency of equipment use.

[0005] Furthermore, when the compression spring is in a non-compressed state, the adjusting screw can extend out of the liquid level end plate.

[0006] Furthermore, an elastic sealing ring is sleeved on the outer peripheral surface of the liquid level end plate.

[0007] Furthermore, a positioning scale line is engraved on the outer surface of the liquid level end plate. The distance between the positioning scale line and the end wall closest to the liquid level end plate is A. The length that the adjusting screw can extend out of the liquid level end plate in the non-compressed state is also A.

[0008] Furthermore, the liquid level regulating plate can completely block the liquid outlet hole.

[0009] The beneficial effects of the utility model are as follows:

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] An energy-saving horizontal screw centrifuge liquid level regulating device, such as Figure 1 and Figure 2As shown, it includes a liquid level end plate 1, which is provided with a plurality of liquid outlet holes 2; a square inner chute 3 is provided inside the liquid level end plate 1 on the outer periphery of the liquid outlet hole 2, the square inner chute 3 is connected to the liquid outlet hole 2, and a liquid level regulating plate 4 is slidably connected in the square inner chute 3. The liquid level regulating plate 4 can completely block the liquid outlet hole 2, and an adjusting screw 5 is provided to pass through the liquid level regulating plate 4 and be threadedly connected to the liquid level regulating plate 4. One end of the adjusting screw 5 passes through the outer periphery of the liquid level end plate 1 and extends to the outside of the liquid level end plate 1. The adjusting screw 5 is rotatably connected to the liquid level end plate 1, and a sliding mounting plate 6 is also slidably connected in the square inner chute 3. A compression spring 7 is provided between the sliding mounting plate 6 and the bottom wall deep in the square inner chute 3. The two ends of the compression spring 7 are respectively fixed to the sliding mounting plate 6 and the bottom wall of the square inner chute 3. The bottom of the adjusting screw 5 is rotatably connected to the sliding mounting plate 6; by rotating the adjusting screw 5, the liquid level adjusting plate 4 can be driven to slide in the square inner chute 3, thereby adjusting the degree to which the liquid level adjusting plate 4 blocks the liquid outlet hole 2.

[0019] like Figure 1 and Figure 2 As shown, in this embodiment, when the compression spring 7 is in a non-compressed state, the adjusting screw 5 can extend out of the liquid level end plate 1; the outer circumferential surface of the liquid level end plate 1 is sleeved with an elastic sealing ring 8; the outer surface of the liquid level end plate 1 is engraved with a positioning scale line 9, and the distance between the positioning scale line 9 and the end wall closest to the liquid level end plate 1 is A. In the non-compressed state, the length that the adjusting screw 5 can extend out of the liquid level end plate 1 is also A; after the liquid level adjusting plate 4 is adjusted, the elastic sealing ring 8 is sleeved to seal the outer circumferential surface of the liquid level end plate 1, and the adjusting screw 5 can also be fully extended into the liquid level end plate 1. At this time, the compression spring 7 is in a compressed state; when the liquid level adjusting plate 4 is driven to move by the adjusting screw 5, the position where the liquid level adjusting plate 4 finally blocks the liquid outlet 2 is judged by the positioning scale line 9.

[0020] The working principle of this utility model is as follows:

[0021] To adjust the liquid level of the liquid level adjustment plate 4, rotate the adjustment screw 5. This rotation drives the liquid level adjustment plate 4 to slide within the square inner chute 3. The liquid level adjustment plate 4 can be moved to different positions, partially or completely blocking the liquid outlet 2. The adjustment screw 5, connected to the sliding mounting plate 6, enables precise control of the liquid level adjustment plate 4.

[0022] The liquid level end plate 1 is provided with a positioning scale 9, which is used to determine the final position of the liquid level adjustment plate 4. When the adjustment screw 5 extends outside the liquid level end plate 1, the degree of sealing of the liquid outlet 2 by the liquid level adjustment plate 4 can be determined by observing the position of the positioning scale 9. After adjustment is completed, the elastic sealing ring 8 is fitted onto the outer circumference of the liquid level end plate 1, ensuring the equipment's sealing performance and adjustment stability. (Since the adjustment screw 5 extends inward a distance (length A) when the elastic sealing ring 8 is subsequently fitted, the position of the positioning scale 9 during the adjustment process corresponds to the position of the end wall of the liquid level end plate 1 after the elastic sealing ring 8 is fitted.)

[0023] When the adjusting screw 5 extends out of the liquid level end plate 1, the compression spring 7 is in a non-compressed state, and the adjusting screw 5 can be freely adjusted on the outside of the liquid level end plate 1; when the adjustment is completed, the elastic sealing ring 8 is sleeved to seal the outer peripheral surface of the liquid level end plate 1, so that the adjusting screw 5 is fully extended into the liquid level end plate 1, and the compression spring 7 enters a compressed state to provide external sealing.

[0024] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
