Based on the above-mentioned problems existing in the prior art, an object of an embodiment of the present application is to: provides a backwater tank, and achieves the effect of avoiding iron filings accumulation.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a return water tank, includes the box, be fixed with water inlet pipe and water pump on the box, water inlet pipe lower extreme and the inside intercommunication of box, the water sucking mouth of water pump and the inside intercommunication of box, the box is circular, the bottom of box is the cambered surface of camber downwards.

Further, the water suction port of the water pump is connected with a water outlet pipe, the water outlet pipe stretches into the box body and is internally connected with a storage box, the storage box is fixed in the box body, the lower end of the storage box is fixedly provided with a water suction pipe, and the lower end of the water suction pipe extends and is close to the bottom of the box body and is used for sucking away impurities accumulated at the bottom of the box body.

Further, a filter screen is fixed at the lower end of the water outlet pipe and is used for filtering impurities.

Further, the upper end of the water suction pipe stretches into the storage box, and the upper end of the water suction pipe is higher than the bottom surface of the storage box, so that impurities are prevented from falling out of the storage box through the water suction pipe.

Further, an inductor is arranged on the box body and used for detecting the water level.

The beneficial effects of the utility model are as follows:

1. because the box body is round, corners of the rectangular box body are not present, and therefore impurities such as scrap iron and the like cannot be accumulated at the corners;

2. because the bottom of box is the cambered surface of camber downwards, impurity such as iron fillings in the cooling water can pile up the bottom in the box owing to self gravity, makes things convenient for impurity to concentrate to retrieve.

Detailed Description

The present utility model will now be described in detail with reference to the accompanying drawings. The figure is a simplified schematic diagram illustrating the basic structure of the utility model only by way of illustration, and therefore it shows only the constitution related to the utility model.

As shown in fig. 1-3, the application provides a water return tank, which comprises a tank body 1, wherein the tank body 1 is circular, and the bottom of the tank body 1 is a cambered surface arched downwards.

The upper end of the box body 1 is fixed with a water inlet pipe 2, the lower end of the water inlet pipe 2 is communicated with the inside of the box body 1, and it can be understood that the upper end of the water inlet pipe 2 is a recovery port of cooling liquid, and the cooling liquid can flow back into the water inlet pipe 2 after being practically used and then flows into the box body 1.

Since the case 1 is circular, there are no corners of the rectangular case, and therefore, impurities such as iron filings are not accumulated at the corners.

The upside of box 1 is fixed with water pump 3, and water sucking mouth of water pump 3 is connected with outlet pipe 4, and outlet pipe 4 stretches into box 1 internally connected and has bin 5, and bin 5 is fixed in inside box 1, and the lower extreme of bin 5 is fixed with the water sucking pipe 6, and the lower extreme of water sucking pipe 6 extends and is close to the inside bottom of box 1.

When the water pump 3 is started, negative pressure is generated at the water suction port of the water pump 3, and the negative pressure sequentially acts on the inside of the box body 1 through the water outlet pipe 4, the storage box 5 and the water suction pipe 6, so that cooling water recovered in the box body 1 is sequentially sucked and recovered by the water pump 3 through the water suction pipe 6, the storage box 5 and the water outlet pipe 4.

Because the bottom of the box body 1 is a cambered surface arched downwards, impurities such as scrap iron in cooling water can be accumulated at the bottom of the box body 1 due to self gravity.

Because the lower end of the water suction pipe 6 extends and is close to the bottom of the inside of the box body 1, the water pump 3 sucks cooling water and simultaneously sucks impurities together.

The lower end of the water outlet pipe 4 is fixedly provided with a filter screen 7, and impurities in the cooling water are filtered out through the filter screen 7, so that on one hand, the impurities are prevented from being sucked into the water pump 3, and the water pump 3 or a subsequent device is prevented from being damaged; on the other hand, the impurities are concentrated and blocked in the inner storage tank 5.

The upper end of the water suction pipe 6 is higher than the bottom surface of the interior of the storage box 5. When the water pump 3 stops working, impurities in the storage tank 5 can be accumulated at the bottom in the storage tank 5 due to the impurities, and the impurities can be prevented from falling back into the tank body 1 through the water suction pipe 6 because the upper end of the water suction pipe 6 is higher than the bottom surface in the storage tank 5, so that the impurities are stored in the storage tank 5, and a worker can conveniently clean and recover the impurities by disassembling the storage tank 5 at any time.

In combination, the effects of automatically and intensively storing impurities and conveniently cleaning and recycling the impurities are achieved.

It can be understood that the upper side of the box 1 is also provided with an inductor 8 for detecting the water level of the cooling water in the box 1, and when the water level of the cooling water is too high, a signal is sent to an external control system, and the external control system starts the water pump 3, so that the water pump 3 is prevented from being started for a long time, and energy is saved.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
