DETAILED DESCRIPTION

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1-2 As shown, the utility model provides a centralized lubrication system for a mechanical agitation flotation machine, wherein the mechanical agitation flotation machine 1 is provided with bearings; the centralized lubrication system 2 is installed on the mechanical agitation flotation machine 1, and the centralized lubrication system 2 includes an oil storage tank 4, a grease pump 3, a metering pump unit 5, and a distributor 9; the oil storage tank 4 is provided with a grease pump 3, and a plurality of metering pump units 5 are arranged around the grease pump 3; the metering pump unit 5 is connected to a safety valve 6 through a connecting pipe, the safety valve 6 is connected to the distributor 9 through a connecting pipe, and the distributor 9 is connected to a plurality of bearings through a connecting pipe. The bearing includes a stirring mechanism bearing 11 and a scraper bearing 12. The distributor 9 includes a stirring mechanism distributor 9-1 and a scraper distributor 9-2; the stirring mechanism distributor 9-1 is respectively connected to a plurality of stirring machine bearings 11 through connecting pipes; the scraper distributor 9-2 is respectively connected to a plurality of scraper bearings 12 through connecting pipes. Each outlet of the stirring mechanism distributor 9-1 and the scraper distributor 9-2 corresponds to a lubrication hole of a bearing. A pressure gauge 7 is arranged on the safety valve 6. A filter 8 is provided on the connecting pipe between the safety valve 6 and the distributor 9. The grease pump 3 is provided with an intelligent controller for controlling the working time and intermittent time of the grease pump.

[0020] When the centralized lubrication system of the mechanical stirring flotation machine is working, the lubricant is injected into the oil storage tank 4, and the working time and the intermittent time of the grease pump 3 are set through the intelligent controller. During the set working time, the grease pump 3 is started to work, and each time the grease pump 3 rotates one circle, the multi-channel quantitative pump unit 5 configured on its periphery completes a telescopic action in turn, thereby quantitatively sucking the lubricant from the oil storage tank 4 and discharging it at high pressure. The lubricant discharged by the quantitative pump unit 5 enters the corresponding safety valve 6, filter 8, and distributor 9 in turn through the connecting pipe.

[0021] There are multiple sets of slide valves in the distributor 9, which have a multi-way distribution function. Under the pressure of the lubricant itself, the slide valve groups can move in sequence. When the metering pump unit 5 completes a suction and discharge action, the corresponding slide valve in the distributor 9 changes direction and pushes the lubricant to one outlet; when the metering pump unit 5 moves for the second time, another corresponding slide valve in the distributor 9 moves to push the lubricant to the next outlet; the metering pump unit 5 keeps moving, the slide valve group of the distributor 9 keeps changing direction, and each outlet discharges the lubricant in sequence and circulates continuously. Each outlet of the distributor 9 corresponds to a lubrication hole of a bearing, so during the working cycle of the grease pump 3, each bearing will be lubricated in a timely and quantitative manner in sequence.

[0022] The centralized lubrication system is provided with a safety valve 6 with a fault alarm function. When a lubrication channel is blocked, the corresponding channel safety valve 6 will be actuated to discharge lubricant to prevent damage to components, and at the same time, an audible and visual alarm will be issued to give a prompt.

[0023] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
