A cooling water system including a sedimentation tank, a vertical filter, and a pressure relief valve was designed. The system uses sedimentation in the sedimentation tank, filtration through the filter cover and the vertical filter, and the pressure relief valve to adjust the water pressure, thereby ensuring the quality of the cooling water, reducing impurities, and lowering the frequency of filter replacement.
The improved cooling water quality reduced the frequency of cooling filter replacement for the cantilever tunneling machine, ensuring continuous operation and effective cooling.

Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of cooling systems, in particular to a tunneling machine cooling water system. BACKGROUND
[0002] The present cantilever type tunneling machine cooling system uses external water for cooling, and DN50 welded pipes are used to guide the production water along the ramp to each section, and after the soft tube is connected with the DN50 welded pipe, it is directly connected with the water inlet of the cantilever type tunneling machine cooling system. After the cantilever type tunneling machine is cooled and cooled, the cooling water heated by the tunneling machine cooling system is drained to the working surface through the soft tube. However, since the present cooling water uses the production water on site, the water quality is extremely unstable and the water pressure is much greater than the suitable water pressure 3-8MPa of the tunneling machine cooling, which can easily lead to poor cooling effect, especially when the sand content of the cooling water is heavy, the cantilever type tunneling machine cooling filter element needs to be replaced every day, which seriously affects the continuous operation.

[0023] To address the aforementioned problems, this application provides a tunneling machine cooling water system. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.
[0024] like Figure 1 The tunneling machine cooling water system shown includes the original tunneling machine cooling system 4, and further includes: a sedimentation tank 1, which is used to perform primary sedimentation, filtration and purification of the cooling water. An inlet pipe 16 is connected to one end of the sedimentation tank 1, which is connected to a water source via a pipeline, and an outlet pipe 13 is connected to the other end. The system also includes a filter cover 14, a pressure relief valve 2, and a vertical filter 3.
[0025] The vertical filter 3 is connected to the water inlet of the original tunneling machine cooling system 4 to filter the water entering the original tunneling machine cooling system. The pressure relief valve 2 is connected to the vertical filter 3 through a pipe to adjust the water pressure entering the original tunneling machine cooling system 4 and maintain its optimal cooling pressure between 3-8 MPa. The filter cover 14 is placed over the outlet of the water pipe 13 to filter the water. The water outlet 13 is connected to the pressure relief valve 2 through a pipe.
[0026] Thus, the system removes the dirt and other impurities in the cooling water that can cause abnormality of the cooling system through the sedimentation tank 1, and filters and purifies the cooling water as much as possible through the filter cover 14 and the vertical filter 3, and finally adjusts the pressure of the cooling water into the original tunneling machine cooling system 4 through the pressure relief valve 2 to achieve the final adjustment of the cooling water. Thus, the cooling water into the original tunneling machine cooling system 4 is clean, the frequency of replacing the cooling filter core of the boom-type tunneling machine is reduced, and the continuity of the operation is ensured.
[0027] In one embodiment, since the domestic water is used as the cooling water on site, some large impurities are inevitable. The application is provided with a sewage basket 17 on the inner wall of the water inlet pipe 16 of the sedimentation tank 1, and the pipe opening of the water inlet pipe 16 is located in the sewage basket 17. Thus, the impurities such as branches are intercepted by the sewage basket 17, and the sewage basket 17 is located at the pool opening of the sedimentation tank 1 to facilitate the regular cleaning of these impurities to avoid blocking the outlet or falling into the sedimentation tank 1. At the same time, the pool opening cover of the sedimentation tank 1 is provided with a pool cover 18 to protect the sedimentation tank 1, and the overflow pipe 15 is arranged above the water outlet pipe 13 close to the pool opening.
[0028] In one embodiment, the vertical filter 3 is a filter with a replaceable filter core to facilitate quick replacement when the vertical filter 3 is blocked. The vertical filter 3 is fixedly arranged on the body of the tunneling machine through fasteners and moves with the boom-type tunneling machine.
