detailed description

Below in conjunction with description accompanying drawing and embodiment the utility model content is described in detail:

Figures 1 to 5 are schematic diagrams of embodiments of a workpiece cleaning water filtration and purification cycle system provided by the utility model.

A workpiece cleaning water filtration and purification circulation system, which includes a fine cleaning filtration cycle; the fine cleaning filtration cycle includes a fine cleaning return pan, a fine cleaning sewage tank, a fine cleaning water tank, and a fine cleaning nozzle connected in sequence; A first filter is provided between the washing return pan and the fine cleaning sewage tank, a second filter is provided between the fine cleaning sewage tank and the fine cleaning water tank, and a second filter is provided between the fine cleaning water tank and the fine cleaning nozzle. There is a third filter, and the fine cleaning nozzle is located directly above the fine cleaning return pan.

During the process of cleaning water from the fine cleaning return pan to the fine cleaning nozzle, it is generally filtered three times:

The first filtration: filter from the fine cleaning backwater pan through the first filter, and flow to the fine cleaning sewage tank. The first filter adopts a paper tape filter with a filtration accuracy of 20-30mu.

The second filtration: the circulating water pump pumps the water from the fine cleaning sewage tank, passes through the second filter, and then filters to the fine cleaning water tank. The second filter adopts a circulating cartridge filter with a filtration accuracy of 10mu.

The third filtration: the cleaning water pump pumps out the water from the fine cleaning water tank, passes through the third filter, and is sprayed onto the workpiece by the fine cleaning nozzle. The third filter uses a cleaning cartridge filter with a filtration accuracy of 10mu.

The engineer found in the experiment that if the cleaning water in the fine cleaning water tank is directly sprayed on the workpiece after only the first and second filtration, the cleanliness cannot reach 10mu. A third filter is arranged between the fine cleaning nozzles, so that the cleaning water is filtered again before spraying.

The paper belt filter is a filter surface formed by spreading the filter paper in the filter channel. The cleaning water flows in from the upper side of the filter paper, and flows out from the lower side after being filtered by the filter paper, so as to achieve the function of filtering the cleaning water.

The structure of circulating cartridge filter and cleaning cartridge filter is similar. They both include a filter cylinder. The upper end of the filter cylinder is provided with a water inlet, and the lower end is provided with a water outlet. The filter cylinder is equipped with a filter screen. After being filtered by the filter screen, it flows out from the water outlet, see Figure 5. The filtration accuracy of the circulation cartridge filter and cleaning cartridge filter is controlled by the filter screen.

A magnetic filter is also provided between the fine washing return pan and the first filter, and the magnetic filter performs split-flow filtration on the water in the fine washing return pan. The magnetic filter uses a magnetic chip conveyor.

The magnetic filter is used to filter the metal debris in the cleaning water, but because the amount of water that the magnetic filter can filter per unit time is low, if the fine washing return pan, the magnetic filter and the first filter are connected in series , will lead to a reduction in the purification efficiency of the entire cleaning cycle.

In the utility model, a shunt pipe is arranged on the conveying pipe connecting the fine washing return pan and the first filter. Part of the cleaning water in the water tray is magnetically filtered, and the other part of the cleaning water in the return water tray for fine washing is directly filtered through the first filter. After several cycles, the magnetic filter can magnetically filter all the cleaning water in the cycle, so that Metal debris in the wash water is kept at a low level.

An oil-water separator is also arranged on the fine cleaning sewage tank. The oil-water separator is used to filter the oil in the cleaning water.

The entire cleaning process of the workpiece cleaning machine usually includes multiple spraying processes, so that the surface of the workpiece, the particle size of the inner cavity, and the cleanliness can meet the process requirements.

In this embodiment, the workpiece cleaning machine includes at least two spray cleaning processes, which are the rough cleaning process of the workpiece and the fine cleaning process of the workpiece. The water used in the rough cleaning process of the workpiece and the water used in the fine cleaning process of the workpiece are separately filtered through the rough cleaning filtration cycle and the fine cleaning filtration cycle.

The workpiece rough washing process and the workpiece fine washing process are carried out in independent workpiece rough washing bins and workpiece fine washing bins respectively.

The coarse cleaning filtration cycle includes a rough cleaning return pan, a rough cleaning sewage tank, a rough cleaning water tank, and a rough cleaning nozzle connected in sequence; a first filter is arranged between the rough cleaning return pan and the rough cleaning sewage tank , a second filter is provided between the coarse cleaning sewage tank and the rough cleaning water tank, a third filter is provided between the rough cleaning water tank and the rough cleaning nozzle, and the coarse cleaning nozzle is located at the front of the rough cleaning return tray above.

During the workpiece cleaning process, the workpieces to be cleaned are transported through the conveying device, the workpiece rough cleaning chamber (the upper part of the workpiece rough cleaning room is equipped with rough cleaning nozzles, and the lower part is equipped Washing nozzle, the lower part is provided with a fine washing return tray) adjacent to or alternately arranged along the conveying direction of the conveying device. Since the workpiece rough washing chamber and the workpiece fine washing chamber need to be provided with a channel for the conveying device to pass through, it is difficult to achieve absolute cleanliness between them. If the seal is tight, the cleaning water in the workpiece rough washing chamber and the workpiece fine washing chamber will fly together, resulting in uneven water volume in the fine washing filtration cycle and the rough cleaning filtration cycle. Operators need to check at all times whether the cleaning water in each filtration cycle is overflowing or insufficient. In order to effectively solve the above problems, the utility model sets a string water circulation system between the fine cleaning filtration cycle and the rough cleaning filtration cycle.

The water series circulation system includes a rough washing compensation mechanism arranged between the fine washing water tank and the rough washing return pan, and a fine washing compensation mechanism arranged between the rough washing water tank and the fine washing return pan.

The rough washing compensation mechanism includes a rough washing compensation pipe connected between the fine washing water tank and the rough washing return pan, and a rough washing serial water circulation for pumping the water in the fine washing water tank to the rough washing return pan Pump;

The fine cleaning compensation mechanism includes a fine cleaning compensation pipe connected between the rough cleaning water tank and the fine cleaning return pan, and a fine cleaning serial water circulation for pumping the water in the rough cleaning water tank to the fine washing return pan Pump.

Both the fine cleaning water tank and the rough cleaning water tank are equipped with water level monitors for monitoring the water level in the tank and controlling the operation of the coarse cleaning serial water circulation pump or the fine cleaning serial water circulation pump.

When the water level monitor in the fine washing water tank detects that the water level in the tank is lower than the set value, it controls the operation of the fine washing serial water circulation pump to pump the water in the rough washing water tank to the fine washing return pan, and the fine washing return water The compensation water in the pan enters the fine cleaning water tank after the first filter and the second filter. When the liquid level of the cleaning water in the fine cleaning water tank is higher than the set value, the fine cleaning serial water circulation pump stops operating.
