[0036] like Figure 1 As shown, a grinding fluid circulation filtration system for a grinding machine includes a grinding fluid tank, a workpiece bed and a sedimentation tank.
[0037] The grinding fluid box is located at one end of the workpiece bed, and a liquid infusion pipe interface is provided on the grinding fluid box, and a liquid infusion pipe for inputting grinding fluid into the workpiece bed is connected between the liquid infusion pipe interface and the workpiece bed;
[0038] A drainage trough is provided on the ground at the side of the workpiece bed for discharging the waste grinding fluid into the sedimentation tank;
[0039] The sedimentation tank is opened on the ground at the other end of the workpiece bed, and a water inlet pipe is connected between the grinding fluid tank and the sedimentation tank, which is used to add the grinding fluid that is reused after sedimentation into the grinding fluid tank;
[0040] A filter is provided on the top of the grinding liquid tank, the water outlet end of the water inlet pipe is connected to the filter, and a grinding mud box is provided on the side of the filter, which is used to collect the sediment filtered out from the filter;
[0041] The infusion pipe and the drainage trough are both located on one side of the workpiece bed, and the water inlet pipe is located on the other side of the workpiece bed. By making the water inlet and outlet pipes located on both sides of the workpiece bed respectively, the two do not affect each other, which is convenient for checking pipe blockage and unblocking the pipe;
[0042] The sedimentation tank is provided with a plurality of sedimentation sub-tanks connected in series, the drainage trough is connected to the sedimentation sub-tank at the head end, and the water inlet pipe is connected to the sedimentation sub-tank at the end;
[0043] The plurality of sedimentation sub-tanks connected in series are all water tanks with openings on the tops, and through pipes are respectively provided between the water tanks connected in series.
[0044] The multiple sedimentation sub-tanks are respectively a primary tank, a secondary tank and a tertiary tank, the primary tank is connected to a drainage trough, and the tertiary tank is connected to a water inlet pipe; wherein the areas of the primary tank to the tertiary tank decrease gradually, the primary tank accounts for 1 / 2 of the total area of the sedimentation tank, the secondary tank accounts for 1 / 3 of the total area of the sedimentation tank, and the tertiary tank accounts for 1 / 6 of the total area of the sedimentation tank.
[0045] The utility model divides the sedimentation tank into a multi-level sedimentation structure, and makes the waste grinding liquid precipitate in a plurality of sedimentation sub-tanks in sequence, so as to have a better sedimentation effect, thereby reducing the generation of sediment in the grinding liquid tank and avoiding the blockage of the pipeline. Example
[0046] A self-priming pump is installed at the upper water layer in the sedimentation tank, and the water inlet pipe is connected to the self-priming pump. On the one hand, it slows down the rotting and damage of the water pump buried in the grinding waste. On the other hand, the self-priming pump draws the upper liquid surface to avoid drawing the bottom waste into the water inlet pipe, thereby reducing the filtering pressure of the filter.
[0047] A water level control device is installed in the sedimentation tank, and the water level control device includes a liquid level gauge installed in the sedimentation tank and a warning light installed above the sedimentation tank. The liquid level gauge and the warning light are connected in series, and the warning light is connected in parallel with the self-priming pump. When the water level in the sedimentation tank reaches the upper limit of the liquid level gauge, the warning light lights up to alarm, and the self-priming pump starts to pump water. After the water level in the sedimentation tank returns to normal, the warning light turns off and the self-priming pump stops pumping water.
[0048] A cover is provided at the top of the sedimentation tank to prevent the odor in the sedimentation tank from emanating. The cover is slidably connected to the top of the sedimentation tank and can be easily opened. A lighting lamp and a proximity switch connected in series are installed at the movable end of the cover. When a staff member approaches, the proximity switch is turned on, the lighting lamp is powered on, and the lighting lamp serves as a reminder. Example
[0049] like Figure 1 As shown, an overflow port is provided on the upper part of the side wall of the grinding fluid tank, and the drainage groove extends to just below the overflow port. In the present application, an overflow port is provided on the grinding fluid tank, and the drainage groove is extended to just below the overflow port. If too much liquid is added to the grinding fluid tank, it can be discharged into the drainage groove through the overflow port, thus avoiding overflow and pollution caused by water inlet pipe during water replenishment.
[0050] like Figure 2 and Figure 3As shown, a sedimentation box is provided in the grinding fluid box. The sedimentation box is a top-opening structure, which is located below the water outlet of the filter. The area and height of the sedimentation box are smaller than the grinding fluid box. The filtered water first falls into the sedimentation box, and the sediment in the liquid settles at the bottom of the box. When the sedimentation box is full of liquid, the upper liquid overflows and flows into the grinding fluid box. The two sides of the sedimentation box are respectively provided with lifting ears for easy lifting. When cleaning the sediment at the bottom of the grinding fluid box, there is no need to enter the bottom of the box for cleaning. You only need to lift the collection box to the outside for cleaning and then replace it. The height of the sedimentation box is smaller than the height of the overflow port, so that the liquid in the sedimentation box will not directly enter the overflow port after overflowing, and will only be retained from the overflow port when it reaches a certain height.
[0051] The infusion tube interface is located at the top of the grinding fluid box and outside the sedimentation box. The infusion tube enters the grinding fluid box from the infusion tube interface and extends to the bottom of the grinding fluid box. The grinding fluid output by the infusion tube does not contain impurities and can avoid the infusion tube being blocked by the sediment at the bottom of the sedimentation box. Example
[0052] The cleaning scheme of the grinding liquid tank of the utility model is as follows: the liquid in the tank is extracted by a sewage pump, and then the sedimentation tank is lifted out of the grinding liquid tank, the sludge at the bottom of the sedimentation tank is cleaned, and after the cleaning is completed, the sedimentation tank is put back into the grinding liquid tank.
[0053] The cleaning scheme of the sedimentation tank of the utility model is as follows: since the sedimentation tank mainly contains sediments with little liquid content, it is only necessary to extract the liquid in the sedimentation tank into the grinding liquid tank through a self-priming pump, and then lift each sedimentation sub-tank out of the sedimentation tank, clean the sedimentation sub-tank, and after the cleaning is completed, put each sedimentation sub-tank back into the sedimentation tank.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of each embodiment of the utility model.
