Central outlet water filtering device with smaller volume and lower cost -- high-pressure cooling filtering system
The technical scheme adopted is: a central effluent filtering device, which is characterized in that it comprises a water tank, a chip removal water tank, a filtering mechanism, an input pipeline, a connecting pipeline, an output pipeline, a low-pressure delivery pump and a high-pressure delivery pump, and the filtering mechanism comprises a filter and a second filter; One end of the input pipe is connected with the outlet of the waste water recovery channel of the machine tool workbench; The other end of the input pipe is connected with the chip conveyor water tank; Both ends of the connecting pipe are respectively connected with the water tank.
The filter and the low-pressure delivery pump are connected and installed on the connecting pipeline. One end of the output pipeline is connected with the water tank, and the other end is connected with the end of the machine tool spindle through a rotary joint; The filter and high-pressure delivery pump are connected and installed on the output pipe. The cooling water in the water tank is delivered to the central through-hole of the main shaft through the high-pressure delivery pump to cool the main shaft. The inclined high-level overflow pipe is connected to the side wall of the water tank, and the bottom end of the high-level overflow pipe is located in the chip cleaning water tank. When the liquid level in the water tank is higher than the top of the high-level overflow pipe, the cooling water will automatically flow into the chip cleaning water tank from the high-level overflow pipe to prevent the water tank from being filled.
As a supplement and improvement of the above technical scheme, the utility model also includes the following technical features.
The filter is a coarse filter and the second filter is a fine filter. The wastewater recovered from the wastewater recovery channel of the machine tool workbench enters the central through-hole of the spindle through two filters, effectively improving the purity of the cooling water.
The wood chip cleaning water tank is separated into two chambers by the filter screen. The input pipe is connected with one chamber, and the connecting pipe and the high-level overflow pipe are connected with the other chamber. The recycled wastewater is filtered by the filter screen first, extending the service life of the filter and the second filter.
The central effluent filtering device also includes a liquid level sensor, which is installed in the chip cleaning water tank to detect the liquid level in the chip cleaning water tank.
A pressure gauge is connected to the output pipe to detect the pressure of cooling water in the output pipe at any time.
By setting a coarse filter and a fine filter, the utility model can achieve the following beneficial effects: 1. The used cooling liquid is filtered twice, the filtering effect of the cooling liquid is good, and the utilization rate of the cooling liquid is improved; 2. Compact structure, small volume, convenient control and low cost. Better production.
Improve cutting speed and tap more productivity in production.
The tool wear is reduced. Reduce the local temperature generated by high temperature during machining, and extend the tool life. Reduce tool replacement frequency and tool consumption.
Improve quality stability and reduce the generation of waste reduction parts.
Improve the surface finish of parts, improve the quality of parts, and improve the market competitiveness of products.
