Thin-film hydraulically excited double-barrel vibrating mill

Abstract

The invention provides a film type hydraulic vibration dual-cylinder vibrating mill. The film type hydraulic vibration dual-cylinder vibrating mill comprises an upper cylinder body, a reset spring group, a film type hydraulic vibrator, a lower cylinder body and a base, wherein the film type hydraulic vibrator is arranged between the upper cylinder body and the lower cylinder body and comprises a film made of a flexible material, a vibration plate I and a vibration plate II; the vibration plate I and the vibration plate II are arranged in parallel; the film is arranged between the vibration plate I and the vibration plate II and forms an enclosed space for accommodating a liquid with the vibration plate I and the vibration plate II individually or together; the vibration plate I or the vibration plate II is provided with a channel; the enclosed space is communicated with a hydraulic source capable of outputting a liquid flow the direction of which can be changed periodically via a channel. A bearing is not required for the vibrating mill; a piston is not required for a hydraulic device; the vibrating mill is simple to manufacture, is convenient to maintain, can steplessly regulate the frequency and amplitude without stop, has no relevance between frequency regulation and amplitude regulation, is low in cost, is strong in vibration force, has no abrasion and leakage, does not need to dissipate heat, is uniform in vibration force distribution, is low in energy consumption, is very tiny in external vibration interference, and generates vibration by utilizing the film type hydraulic vibrator for milling operation.

Description

technical field [0001] The invention relates to a thin-film hydraulically excited double-cylinder vibration mill. Background technique [0002] Existing vibrating mills use mechanical exciters or vibrating motors as excitation sources to generate vibrations, and most of them are non-near-resonant vibrating mills. The disadvantages are: when the vibration force is large and the speed is high, one or two Therefore, multiple exciters have to be used and work away from the resonance point, which results in high energy consumption and low efficiency. [0003] Above-mentioned situation causes existing vibrating mill to have following deficiency: [0004] 1) The lubrication, heat dissipation, sealing, and transmission between the bearing and the shaft become very complicated, which brings many difficulties to manufacturing, installation, and maintenance, and also reduces reliability. [0005] 2) It is necessary to stop the machine to adjust the vibration amplitude of the machine....

AI Technical Summary

Problems solved by technology

[0002] Existing vibrating mills use mechanical exciters or vibrating motors as excitation sources to generate vibrations, and most of them are non-near-resonant vibrating mills. The disadvantages are: when the vibration force is large and the speed is high, one or two The exciter is not competent, so multiple exciters have to be used, and work away from the resonance point, with high energy consumption and low efficiency

[0004] 1) The lubrication, heat dissipation, sealing and transmission between the bearing and the shaft become very complicated, which brings many difficulties to manufacturing, installation and maintenance, and also reduces the reliability

[0005] 2) It is necessary to stop the machine to adjust the amplitude of the machine

[0006] 3) The vibration force of the vibrator is concentrated and cannot be evenly distributed, which makes the structure not well stressed

[0007] 4) It is difficult to make multiple exciters work in parallel and synchronously

[0008] 5) Due to the high vibration intensity, many dynamic loads are transmitted to the ground, causing interference to the working environment
