Description

Technical Field

[0001] The utility model relates to the technical field of pusher centrifuges, in particular to a counterweight-free pusher centrifuge anti-vibration structure. Background Art

[0002] A pusher centrifuge is a continuously operated, high-efficiency, filtration-type centrifuge. During operation, the drum assembly rotates at high speed, with the first drum rotating and reciprocating back and forth, continuously pushing the filter cake into the next drum and ultimately out of the centrifuge. During operation, the hydraulic system's reversing mechanism, distribution, and pushing motions generate a certain amount of vibration in the centrifuge. To ensure safe and stable operation, an anti-vibration structure consisting of a vibration damping frame, rubber cushions, and reinforced concrete or cast iron counterweights is used between the pusher centrifuge and the mounting platform. The rubber cushions are installed between the upper and lower vibration damping frames, beneath the counterweights. The centrifuge and counterweights are rigidly connected, forming a single structure with increased inertia, which reduces the amplitude and frequency of the centrifuge's vibrations during operation. However, reinforced concrete counterweights require on-site fabrication, which can be time-consuming. Castings are also expensive, and to achieve good vibration damping, the counterweights occupy a considerable amount of space. Therefore, a cost-effective, anti-vibration structure for a pusher centrifuge without counterweights is proposed. Summary of the Invention

[0003] The purpose of the utility model is to solve the above problems and to propose a counterweight-free pusher centrifuge anti-vibration structure.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a vibration-proof structure of a counterweightless pusher centrifuge, which is characterized by including a lower base plate fixed on a mounting platform, an upper base plate connected to the centrifuge, and a plurality of first buffer pads and second buffer pads respectively installed between the lower base plate and the upper base plate and on the upper base plate to reduce the vibration amplitude and vibration frequency of the centrifuge.

[0005] Preferably, the first buffer pad and the second buffer pad are both rubber buffer pads.

[0006] Preferably, upper substrate positioning pins and lower substrate positioning pins for positioning the first buffer pad are respectively installed on the upper substrate and the lower substrate.

[0007] Preferably, the second buffer pad is provided with a locking bolt which passes through the second buffer pad and the upper base plate in sequence and connects with the lower base plate.

[0008] Preferably, a threaded seat connected to a locking bolt is provided on the lower base plate.

[0009] Preferably, a locking nut capable of adjusting the degree of compression of the upper base plate is also installed on the locking bolt.

[0010] Preferably, a plurality of anchor bolts for fixing the lower substrate are further installed on the lower substrate; nuts are installed on the anchor bolts.

[0011] Preferably, a spring washer is installed between the nut and the lower substrate.

[0012] The beneficial effects of the present utility model are as follows: By installing the first buffer pad and the second buffer pad between the upper substrate and the lower substrate and on the upper substrate respectively, the vibration generated during the operation of the centrifuge is blocked by the first buffer pad and the second buffer pad, so that the energy is dissipated, the vibration amplitude and vibration frequency of the centrifuge are reduced, the stable operation of the centrifuge is ensured, and the use cost is also reduced. At the same time, it also plays the role of reducing the resonance amplitude of the mechanical structure and weakening the vibration transmission. Description of the Drawings
