[0035] Embodiment 1:

[0036] See also Figures 1 to 3 , a slag dam water intake and filtering device, the slag dam water intake and filtering device comprising:

[0037] A slag dam 1 is set up in an area with gentle water flow;

[0038] A water delivery pipeline 5 is arranged in the middle of the slag dam 1, and the water delivery pipeline 5 includes a water inlet section 4 and a diversion section 9. The diversion section 9 is located on one side of the slag dam 1, and one end of the diversion section 9 close to the slag dam 1 is connected to one end of the water inlet section 4, and the other end of the water inlet section 4 passes through the slag dam 1 and extends in a direction away from the slag dam 1;

[0039] Among them, a filter screen 2 is provided at one end of the water inlet section 4 away from the slag dam 1, and a water storage tank 6 is connected to one end of the diversion section 9 away from the slag dam 1. A water outlet 7 is provided on the side wall of the water storage tank 6, and the height of the water outlet 7 is lower than the height of the water inlet section 4.

[0040] Specifically, the slag dam 1 is narrow at the top and wide at the bottom. Since the liquid is affected by gravity and has fluidity, there is pressure in all directions inside the liquid, and the pressure of the liquid increases with the depth, that is, the deeper it is, the greater the pressure inside the liquid. Therefore, the slag dam 1 is built into a trapezoidal shape that is narrow at the top and wide at the bottom to increase the ability to withstand the pressure generated by water; a hole is provided at the upper end of the water storage tank 6 to allow the diversion section 9 to pass through, and one end of the diversion section 9 away from the slag dam 1 is welded and fixed to the upper end of the water storage tank 6 through the hole; a hole is provided on the side wall of the water storage tank 6 to allow the water outlet 7 pipe to pass through, and one end of the water outlet 7 pipe is welded and fixed to the side wall of the water storage tank 6 through the hole; the connection between the water supply pipeline 5 and the slag dam 1 should be tightly connected to prevent water leakage and loosening;

[0041] In this embodiment, the slag dam 1 is set in the area where the water flow is gentle, which can play a role in preliminary sedimentation of the water flow and realize preliminary filtration of the water flow. When the water flow enters the diversion section 9 through the water inlet section 4, due to the filtering effect of the filter screen 2, large pieces of waste slag and impurities are filtered out. This process is secondary filtration. After the secondary filtered water flows through the diversion section 9 and enters the water storage tank 6, the impurities in the water are once again gathered and precipitated at the bottom of the water storage tank 6, thereby realizing the third filtration of the water flow. The clean water after the third filtration flows into the sprinkler truck through the water outlet 7. At this time, the water quality meets the standard and meets the demand for high-quality clean water for equipment such as mine sprinkler trucks.

[0042] In this embodiment, the water flow is filtered three times to remove a large amount of waste residue, debris and other pollutants mixed in the water body during the flood season, so as to ensure that the water quality used by the sprinkler truck meets the standards, thereby reducing the risk of equipment wear and failure, thereby protecting the normal operation of equipment such as sprinkler trucks and extending their service life.

[0043] In this embodiment, the height of the water outlet 7 is lower than the height of the water inlet section 4, so that the water flow can enter the water storage tank 6 by gravity without the need to install equipment such as a water pump, so that the device has extremely low energy consumption during operation, which meets the requirements of energy conservation and environmental protection, reduces operating costs, and reduces the impact on the environment; the water storage tank 6 not only provides a buffer space and storage space for the water flow, but also a place for the sediment to gather.

[0044] In addition, the pipes and water storage tanks 6 used in this embodiment are made of durable, corrosion-resistant and wear-resistant materials, so that the device can maintain good performance during long-term use. In actual use, the aperture of the filter 2, the water inlet section 4, the diversion section 9 and the pipe diameter parameters of the water outlet 7 can be set according to the actual situation to achieve water filtration with different flow rates and water quality requirements.

[0045] Embodiment 2:

[0046] See also Figures 1 to 4 Based on the first embodiment, further and optionally, the end of the water inlet section 4 close to the slag dam 1 is a horizontal section a, and the end away from the slag dam 1 is a vertical section b, and the filter screen 2 is sleeved on the vertical section b;

[0047] The horizontal section a and the vertical section b are connected by a quick connector or a flange and have the same pipe diameter, and the opening of the vertical section b faces upward.

[0048] Specifically, the horizontal section a is arranged in the middle of the slag dam 1, and one end of the horizontal section a extends in the direction away from the slag dam 1 until it is connected with the end of the vertical section b close to the slag dam 1. The end of the vertical section b away from the slag dam 1 is sleeved with a filter screen 2, and the opening of the vertical section b faces upward to facilitate water flow into the vertical section b through gravity. The horizontal section a and the vertical section b are connected by a quick joint or flange with good sealing performance (not shown in the figure) to make the horizontal section a and the vertical section b easy to disassemble, maintain and replace. In addition, the connection should ensure no leakage;

[0049] In this embodiment, the specifications of the horizontal section a and the vertical section b are DN325mm.

[0050] Further and optionally, a plurality of filter holes 3 are provided on the vertical section b, and the filter holes 3 are round holes or plum blossom holes.

[0051] Specifically, by opening a plurality of filter holes 3 on the vertical section b, water can not only enter the vertical section b through the opening of the vertical section b, but also enter the vertical section b through the filter holes 3. Due to the limitation of the filter holes 3, impurities with larger particle sizes are difficult to enter the pipeline, which can increase the water intake and further improve the filtering effect.

[0052] In this embodiment, the pore size of the filter hole 3 is between 1-2 cm.

[0053] Further and optionally, the end of the diversion section 9 close to the slag dam 1 is a horizontal section c, and the end away from the slag dam 1 is a vertical section d;

[0054] Among them, the horizontal section c and the vertical section d are connected by a quick connector or a flange and have the same pipe diameter. The pipe diameters of the horizontal section c and the vertical section d are smaller than the pipe diameters of the horizontal section a and the vertical section b, and the opening of the vertical section d faces downward.

[0055] Specifically, the horizontal section c and the vertical section d are connected by a quick connector or a flange (not shown in the figure), so that the horizontal section c and the vertical section d are easy to disassemble, convenient for maintenance and replacement. In addition, the connection should ensure no leakage;

[0056] The pipe diameters of the horizontal section c and the vertical section d are smaller than those of the horizontal section a and the vertical section b, that is, the pipe diameter of the water inlet section 4 is larger than that of the diversion section 9. According to the Bernoulli equation, when the fluid enters the small diameter from the large diameter pipe, its pressure will drop. In this way, the pressure on the diversion section 9 is reduced and its service life is improved.

[0057] In this embodiment, the specifications of the horizontal section c and the vertical section d are DN160mm.

[0058] Further and optionally, the horizontal segment a and the horizontal segment c are integrally formed and a connection between the two is an arc transition.

[0059] Specifically, the arc transition at the connection between the horizontal section a and the horizontal section c can avoid a sharp change in pressure when water flows through, which would cause great damage to the pipeline. At the same time, the integral molding of the horizontal section a and the horizontal section c can prevent leakage problems, improve the sealing of the pipeline, and increase the strength of the pipeline.

[0060] Further and optionally, a mud discharge valve 8 is provided at the bottom of the water storage tank 6 .

[0061] Specifically, in order to prevent excessive accumulation of sediment and affect the filtering effect, a mud discharge valve 8 is set at the bottom of the water storage tank 6, and the staff can regularly open the mud discharge valve 8 for cleaning, thereby ensuring the long-term stable operation of the device.

[0062] Further and optionally, the filter screen 2 is mounted on the vertical section b in a detachable connection manner, and the outer surface of the filter screen 2 is wrapped with a geotextile.

[0063] Specifically, the mesh size of the filter 2 is precisely calculated to effectively block large pieces of waste residue without excessively obstructing the water flow. The filter 2 is detachably installed to facilitate regular cleaning and replacement. Geotextiles or other filter materials can be added to enhance the filtering effect. In daily operation, a dedicated person is arranged to regularly check the condition of the filter 2. If it is found to be damaged or blocked, it will be repaired or cleaned in time.

[0064] Further and optionally, the filter screen 2 is made of high-strength, corrosion-resistant metal material.

[0065] Specifically, the high-strength, corrosion-resistant metal material can extend the performance of the filter 2 and prolong its service life.

[0066] In addition, it should be noted that during the operation of the device, strict operating specifications and maintenance systems should be established. When opening and closing the device, the operator should follow the prescribed steps to avoid damage to the equipment or affecting the filtering effect due to misoperation. Regularly inspect the appearance of the device to check for obvious damage, leakage, etc. Especially after rainfall, the water is turbid, and the filter 2, water storage tank 6, etc. inside the device should be inspected and cleaned in detail in a timely manner.

[0067] For the vulnerable parts of the device, such as filter screen 2, seals, etc., a certain number of spare parts should be stored so that they can be replaced in time when needed. Regularly carry out comprehensive maintenance of the device, including cleaning the dirt in the pipeline and checking the flexibility of the valve.

[0068] In addition, in order to improve the operating efficiency and service life of the device, it is also necessary to train operators to familiarize them with the structure, principle, and operation and maintenance methods of the device. At the same time, equipment operation files should be established to record the operating time, maintenance status, fault handling and other information of the device to provide data support for subsequent optimization and improvement.

[0069] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
