Description

A ball nut mechanism shaft-pivot push-flow aerator

technical field

The invention relates to a plug-flow aerator for sewage treatment, in particular to a ball-nut mechanism shaft-pivot push-flow aerator.

technical background

Push-flow aeration is the core of sewage treatment. Aeration equipment is the mechanical equipment that adds air to sewage. Surface aeration and bottom aeration equipment are generally used when new sewage treatment plants are newly built. However, some sewage treatment plants meet discharge standards during construction. It is relatively low, and the standard will be upgraded in the later stage to increase the amount of aeration and oxygenation. The most hope is to directly increase the equipment, without changing any inherent settings. , all due to defects such as loose structure, weak overall planning system, poor adaptability to working conditions, etc., users are not satisfied, especially the equipment is inconvenient to repair and maintain. Once the traditional equipment underwater bearings fail, cranes, etc. Lifting equipment and tools can only be operated outside the sewage pool, which is very cumbersome, and the maintenance cost is high. Users are eager to meet the needs of reliable and efficient products that can be operated and repaired directly on the equipment platform. This ball nut mechanism pivot push The flow aerator was invented in response to this requirement. It created a ball nut mechanism and a pivot-type rotating device, which can meet the underwater fixed state during work and the maintenance state when it is transferred to the water during maintenance, completely solving the inconvenience of maintenance and replacement. technical problems.

The device is fixed on the upper fixing plate, and the lower fixing plate is fixed and connected with the T-shaped bolts embedded in the fixed seat of the rotating body through nuts. The other side of the pivoting rotating body is provided with hinge lugs, and the hinge lugs pass through the hinge bolts. The rod is connected to the hinge turning lug, the hinge turning lug is connected to the upper end of the threaded tie rod, and the threaded tie rod is passed through the ball nut. The outer ball head of the ball nut and the inner spherical surface of the ball nut seat are in a spherical 360° rotating pair.

The ball nut seat 2, the pivot rotating seat 6 and the rotating body fixing seat 8 are arranged on the upper plane of the supporting body 1 at a reasonable distance, and are fixedly connected as a whole. and the upper hinge rotating lug, the outer ball head of the ball nut is hingedly connected to the inner spherical surface of the ball nut seat 2, the outer ball head of the ball nut and the inner spherical surface of the ball nut seat form a spherical 360° rotating pair state, the ball The upper end of the nut mechanism is connected by the hinge lug and the hinge lug 4 on the shaft pivot rotating body 7 through the hinge screw bolt 5. Relative rotation occurs, the middle screw of the ball nut mechanism and the ball nut are in the state of a threaded connection rotating pair. Through the circumferential rotation of the ball nut, the screw is pulled to move axially. They are composed of fixed holes, they are in a triangular shape that meets the functional requirements of the structure, the pivot is arranged in the middle position, and embedded in the pivot rotating seat 6, the pivot and the pivot rotating seat are in the state of a door-pivot revolving pair, and at the same time The pivoting body 7 is connected and fixed by the fixing hole body and the rotating body fixing seat 8 through the T-shaped bolt device 9, and the driving pushing device 10 is fixed on the pivoting body 7, and is arranged obliquely at a certain angle, and the blower 11 is fixed on On the supporting body 1, it is connected to the driving push-flow device by the gas pipeline at the same time. The drive push-flow device 10 is fixed and rotated synchronously with the pivot rotating body 7. Through the ball nut mechanism, the pivot rotating device and the T-bolt Coordinated fixation and rotation.

The advantages of the present invention are: compact and practical structure, powerful and reliable function, the ball nut mechanism and pivot combination are attached to the reasonable size of the support body and the fixed arrangement of the space, so as to realize the fixing and stability of the driving push flow device during work and the rotation during maintenance And displacement, to meet the requirements of work and maintenance are completed on the support body. Compact structure, novel design, reliable and practical, safe and convenient.
