Description

A dewatering screen with a rapid drainage mechanism

Technical field

The utility model relates to the technical field of dewatering screens, in particular to a dewatering screen with a rapid drainage mechanism.

Background technique

The main function of the dewatering screen is dehydration, desliming and demediation. It can be used for sand washing in sand and gravel plants, coal slime recovery in coal preparation plants, dry discharge of tailings in ore dressing plants, etc. Therefore, it is also called sand and gravel dewatering screens, mining dewatering screens, and coal dewatering screens. Mud dewatering screen, tailings dewatering screen, etc.;

The components of the centrifugal force generated by the two sets of eccentric masses of the dehydration screen are superimposed along the vibration direction, and the reverse centrifugal force is offset, thereby forming a single excited vibration along the vibration direction, causing the screen box to make reciprocating linear motion;

After actual use, it was found that the dewatering screen has the following shortcomings:

The rubber spring at the base of the dehydration screen is used to absorb shock, so that the amplitude is not large and the vibration is slow, so that the dehydration screen can be removed cleanly. However, the screen mesh is fixed to the dehydration screen frame, and the materials on the screen continue to move outward with the vibration of the dehydration screen frame. The contact with the screen is small, the water flows downward through the screen holes, and the materials are easy to accumulate and block the screen holes;

And when the existing screen is dehydrated, the water in the material flows downward from the screen hole through the vibration of the screen, and is discharged through dripping. It takes a certain amount of time to perform the drainage operation, and the dehydration speed is slow, while the material in the upper layer flows along with the screen. Moving outward, most of the entrained water has not been filtered out, resulting in poor dehydration effect;

Therefore, this application provides a dewatering screen with a rapid drainage mechanism to meet the needs.
