Description

Technical Field

[0001] This utility model relates to the field of coal mine tunneling drainage technology, specifically to a drainage device for a tunneling face. Background Technology

[0002] During coal mine tunneling operations, due to the complex and ever-changing strike and dip conditions of the coal seam, construction workers often face long and arduous downhill tunneling tasks. In particular, under continuous high-intensity operation, the large amounts of water required for the cooling system of the roadheader, the necessary water used for drilling operations, and various types of wastewater, such as sewage discharged for dust flushing, tend to accumulate in the tunneling face area. This accumulation of wastewater not only occupies valuable working space but also exacerbates the problem of water-slag mixture buildup in the downstream area, thus severely restricting the overall operational efficiency of the face. Effective measures are urgently needed to address this issue promptly.

[0003] Of particular concern is that during the coal seam cutting operation, the cooling water system of the roadheader often needs to be kept running for extended periods to ensure the normal operation of the equipment. However, this practice inevitably leads to a large amount of cooling water entering the coal flow system and flowing along the transportation route with the coal. This undoubtedly exacerbates the difficulty of managing industrial water along the route and puts greater pressure on the mine's water resource management and environmental protection efforts.

[0004] Furthermore, the steep slopes of downhill tunnels place higher demands on drainage equipment due to these unique geological conditions. Traditional single-unit air pumps often lack sufficient power to meet the demands of efficient drainage, resulting in low drainage efficiency. Even more challenging is the tendency for solid waste such as coal gangue to clog the suction inlets and drainage pipes. This not only affects the normal operation of drainage equipment but also poses a series of safety hazards, seriously threatening the safety and progress of tunneling operations. Therefore, effectively addressing the issues of wastewater accumulation and coal gangue buildup during downhill tunneling has become a pressing technical challenge in coal mine tunneling operations. Utility Model Content

[0005] To address the shortcomings of existing technologies, a drainage device for tunneling faces is proposed, which solves the problems of wastewater accumulation and gangue buildup during downhill tunneling as described in the background.

[0006] To achieve the above objectives, the present invention proposes the following technologies:

[0007] A drainage device for a tunneling face includes a water tank. One side of the water tank is connected to the sewage at the front of the roadheader via a pipeline to collect the sewage and store it. The other side of the water tank is connected to a discharge pipeline to discharge the wastewater in the tank.

[0008] Furthermore, a baffle is installed inside the water tank, which is set perpendicular to the direction of the incoming sewage to intercept coal gangue impurities in the incoming sewage.

[0009] Furthermore, the baffle divides the water tank into a front water tank and a rear water tank, and the baffle is provided with evenly distributed mesh holes to filter the wastewater at the front and prevent coal gangue from clogging the discharge pipeline.

[0010] Furthermore, it also includes a sliding platform, on which the water tank is fixedly installed. The sliding platform moves synchronously with the roadheader to maintain a constant relative distance from the approach.

[0011] Furthermore, the sliding platform includes a slide rail and a trailer. There are two slide rails arranged horizontally opposite each other, and the trailer is located between the two slide rails. The water tank is fixedly connected above the trailer.

[0012] Furthermore, a guide head is provided on the front side of the slide, the guide head has an angle with the horizontal plane, and the lower surface of the guide head has a smooth arc-shaped structure.

[0013] Furthermore, the water tank is provided with connectors on the front and rear sides, and the connectors are connected to the front air pump or the rear air pump through rubber hoses to enable the front wastewater to enter and exit the water tank.

[0014] Furthermore, the connector is provided in multiple parts, each with a different diameter to connect to hoses of different diameters, thereby facilitating connection to a blower to achieve water pumping and drainage.

[0015] Compared with the prior art, the comprehensive effects brought about by this utility model include:

[0016] This application utilizes a water tank to facilitate the collection of wastewater from the tunnel face. This system allows for the continuous storage of water while simultaneously ensuring that impurities such as coal slurry and rock slurry in the wastewater settle at the bottom, facilitating the discharge of wastewater from the tank. This prevents coal and gangue impurities from clogging the wastewater discharge pipes, achieving continuous drainage. This effectively solves the problem of difficult drainage at the tunnel face during downhill tunneling, ensuring the safe operation of the tunneling machine and improving the standardization of the tunneling face's quality.

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figs. 1 to 3 As shown, a drainage device for a tunneling face includes a water tank 1. One side of the water tank 1 is connected to the sewage at the front of the roadheader via a pipeline to collect the sewage and store it as intermediate water. The other side of the water tank 1 is connected to a discharge pipeline to discharge the wastewater in the water tank 1.

[0024] By setting up water tank 1, it is convenient to collect wastewater from the face. While realizing the intermediate water storage, the setting of water tank 1 can also allow impurities such as coal sludge and rock mud in the wastewater to settle at the bottom, which is conducive to the discharge of wastewater from water tank 1. This avoids the blockage of wastewater discharge pipeline by coal gangue impurities, realizes the continuous drainage function, effectively solves the problem of difficult drainage at the face during the downhill tunneling, ensures the safe operation of the tunneling machine, and improves the quality standardization of the tunneling face.

[0025] In the tunneling face drainage device of this embodiment, a baffle 2 is provided in the water tank 1. The baffle 2 is set perpendicular to the direction of the sewage inlet at the face to intercept coal and gangue impurities in the sewage at the face.

[0026] The baffle 2 is installed to reduce the impact of the incoming wastewater into the water tank 1 on the inner wall of the water tank 1, and to intercept large fixed particles of impurities in the wastewater, so as to prevent impurities in the wastewater from entering the drainage pipe and causing blockage.

[0027] In the tunneling face drainage device of this embodiment, the baffle 2 divides the water tank 1 into a front water tank and a rear water tank. The baffle 2 is provided with evenly distributed mesh holes to filter the wastewater at the face and prevent coal gangue from clogging the discharge pipeline.

[0028] Specifically, the pumping pipeline draws the wastewater from the front of the tunneling machine into the front water tank. Under the filtration effect of baffle 2, impurities such as coal slime and rock slime are deposited at the bottom of the front water tank, while the filtered wastewater passes over baffle 2 and enters the rear water tank, and is then discharged through the discharge pipeline. The above structure not only stores water but also settles coal slime, and prevents the settled impurities from mixing with the wastewater again.

[0029] The tunneling face drainage device in this embodiment also includes a sliding platform. The water tank 1 is fixedly installed on the sliding platform. The sliding platform moves synchronously with the tunneling machine to maintain a constant relative distance from the face.

[0030] The water tank 1 is installed via a sliding platform, enabling it to move automatically with the machine. This keeps the relative distance between the water tank 1 and the machine head constant, eliminating the need for additional movement. As a result, the paths of the pumping and discharging pipes remain relatively fixed, preventing damage caused by stretching and ensuring normal drainage.

[0031] In the tunneling face drainage device of this embodiment, the sliding platform includes a slide rail 3 and a trailer 4. There are two slide rails 3 arranged horizontally opposite each other. The trailer 4 is located between the two slide rails 3, and the water tank 1 is fixedly connected above the trailer 4.

[0032] Specifically, a trailer 4 is installed on the two slide rails 3. The water tank 1 is placed on the slide rail 3 as a whole by the trailer 4 on the slide rail 3. The water tank 1 is rectangular in shape, and its length is set along the extension direction of the slide rail 3 and is consistent with the tunneling direction of the tunneling machine.

[0033] In the tunneling face drainage device of this embodiment, a guide head 5 is provided on the front side of the slide 3. The guide head 5 has an angle with the horizontal plane, and the lower surface of the guide head 5 has a smooth arc structure.

[0034] By setting the guide head 5, the collision between the slide 3 and the traveling surface is reduced. The arc contact surface on the lower side of the guide head 5 is used to flatten the traveling surface, reduce the bumps of the water tank 1, and improve the overall stability of the drainage device.

[0035] In the tunneling face drainage device of this embodiment, the front and rear sides of the water tank 1 are respectively provided with joints 6. The joints 6 are connected to the face air pump or the rear air pump through rubber hoses to realize the entry and exit of face wastewater into the water tank 1 and the discharge of water tank 1.

[0036] The front connector 6 can be connected to the front air pump with a rubber hose to pump the front wastewater into the water tank 1. The baffle 2 in the middle of the water tank 1 divides the water tank 1 into two parts: the front part and the rear part. After the front wastewater enters the front water tank, impurities such as coal slime and rock slime are deposited at the bottom, while the wastewater passes over the baffle 2 and enters the rear water tank. Then it is discharged by the rear air pump through the rubber hose.

[0037] In the tunneling face drainage device of this embodiment, multiple joints 6 are provided, and the diameters of the multiple joints 6 are different to connect rubber hoses of different diameters, thereby facilitating the connection of air pumps to realize water pumping and drainage.

[0038] Specifically, multiple φ51, φ19, and φ13 water pipe joints 6 are respectively installed on the front and rear surfaces of the water tank 1 to meet the connection requirements of different pipelines. The joints 6 are connected and other joints 6 are sealed according to the actual situation, which is adapted to the water volume of the headwaters in different working faces.

[0039] Preferred, such as Fig. 3 As shown, two φ51 connectors 6 are provided on the front side of water tank 1, both located at the bottom of the front side of water tank 1. They are suitable for using large-diameter hoses in conjunction with air pumps to extract the headwaters of mixed coal gangue. Three different diameter connectors 6 are provided on the rear side of water tank 1. The three sets of connectors 6 are located at the upper part of the rear side of water tank 1. They are used to connect hoses to discharge filtered wastewater according to different needs. The higher position of the rear connectors 6 allows the filtered wastewater to further settle in the rear water tank, reducing the content of fine particles in the extracted wastewater and preventing blockage.
