Detailed Description

The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.

Example (b): clearance water tank assembly, including main water tank 1, expansion tank 2 and No. two expansion tanks 3 all are connected and communicate with main water tank 1, and main water tank 1, expansion tank 2 and No. two expansion tanks 3 form the body that the shape is "Contraband" shape jointly, and this body is under machining center.

Auxiliary water tank 2 is connected with water pump 4 No. one, water pump 4's the end of intaking is connected with auxiliary water tank 2 No. one, water pump 4's play water end is connected with three-way pipe 5, the one end of three-way pipe 5 is connected with auxiliary water tank 3 No. two, the other end of three-way pipe 5 is connected in order to wash into main water tank 1 with the piece and the cooling water that cut formation in the machining center jointly in the machining center, 1 length direction's of main water tank both sides are equipped with a lower mouth of a river respectively in order to cut the piece and the cooling water that form in the machining center and lead to main water tank 1 in.

A discharge cutting machine 9 is provided along the length of the main water tank 1, and after the cooling water and the debris group in the machining center enter the main water tank 1, the debris falls into the bottom of the main water tank 1 because the density of the large debris is higher than that of the cooling water. The bottom debris is scraped from one end of the main tank 1 away from the main tank 1 by the action of the discharge cutter 9.

After the water in the first auxiliary water tank 2 is pumped into the second water by the first water pump 4, the water level of the first auxiliary water tank 2 is lowered, and the cooling water in the main water tank 1 with part of fine debris is brought into the first auxiliary water tank 2 by the first water pump 4. Since the cooling water in the secondary water tank 3 needs to cool down the cutter shaft of the machining center, the cooling water in the secondary water tank 3 needs to be removed as much as possible when being pumped into the machining center. The outer side of the second auxiliary water tank 3 is connected with a second water pump 6, the water inlet end of the second water pump 6 is connected with the second auxiliary water tank 3, the water outlet end of the second water pump 6 is connected with a centrifugal filter 7, the water outlet of the centrifugal filter 7 is connected with a machining center, and the centrifugal filter 7 can be BFS3-40RD in type.

The action process is as follows:

the first water pump 4 is started, the first water pump 4 pumps cooling water in the first auxiliary water tank 2, chip groups of a machining center are flushed into the main water tank 1 from a water outlet through the cooling water at one end of the three-way pipe 5, large-sized chips are settled, and then the large-sized chips are scraped out of the main water tank 1 by the discharge cutting machine 9.

After the water in the first auxiliary water tank 2 is pumped into the second auxiliary water tank 3 by the first water pump 4 through the other end of the three-way pipe 5, the water level of the first auxiliary water tank 2 is reduced, the main water tank 1 with part of fine scraps and cooling water in the main water tank 1 enter the first auxiliary water tank 2 under the action of the first water pump 4, and the fine scraps in the first auxiliary water tank 2 enter the second auxiliary water tank 3 along with the first water pump 4; under the action of the second water pump 6, the cooling water in the second auxiliary water tank 3 is simultaneously pumped into the centrifugal filter 7, so that the water level of the second auxiliary water tank 3 is also reduced, and the cooling water in the main water tank 1 also simultaneously flows into the second auxiliary water tank 3. When the one end of a water pump 4 passes through the three-way pipe 5 and increases the cooling water in No. two expansion tanks 3, No. two cooling water in the expansion tank 3 can be mixd to a water pump 4, therefore, tiny piece in No. two expansion tanks 3 can not deposit in No. two expansion tanks 3, No. two expansion tanks 3 can be from the clearance and keep its bottom not have tiny piece, tiny piece is stirred by a water pump 4 in No. two expansion tanks 3 in by No. two water pump 6 suction to centrifugal filter 7 in, sediment box 11 is installed in order to collect the tiny piece that filters out in centrifugal filter 7's bottom.
