Description

Technical Field

[0001] This invention relates to the field of mining coatings and spraying equipment, and in particular to a special HBK auxiliary material for mining and its spraying system. Background Technology

[0002] In my country, 90% of coal mines are underground. Throughout the coal production process, factors such as production-related sparks, radioactive radiation, noise, toxic and harmful gases, adverse underground weather conditions, poor flame retardancy and antistatic properties of coal and wood materials, and poor lighting in the tunnels are all significant hazards to coal miners. Existing survey data also indicate that some regions have high levels of naturally occurring radioactive nuclides in coal, making radon exposure in coal mines a serious concern. The main hazards of radon and its decay products include: ① killing and damaging cells, a major cause of lung cancer in mines. During the decay of radon and its decay products, alpha particles are emitted that directly ionize the basal cells of various bronchial epithelial cells, thus forming the pathological basis for basal cell carcinogenesis; ② damaging epidermal tissues, such as causing dry skin, hair loss, and nail loss; ③ damaging the sensory organs, such as causing cataracts and glaucoma. In addition, although the main and auxiliary roadways and transport roadways in my country's coal mines are generally equipped with dedicated lighting fixtures, the lighting is not satisfactory. Many coal roadways do not even have the most basic lighting fixtures installed. Workers can only rely on the headlamps of their miners to move forward every day. The obstructed vision of the workers leads to a high accident rate. This safety hazard has been a constant concern for the lives of coal miners.

[0003] Most existing mining coatings are made of cement slurry, concrete, or polyurethane, and their functions are relatively limited. They are also weak in terms of flame retardancy, radiation shielding, noise reduction, fire resistance, weather resistance, meeting the needs of adverse underground weather conditions, and improving tunnel lighting, and cannot meet people's needs.

[0038] HBK special-structure auxiliary material for mining is a "new type of safe and healthy surface spraying protective material for coal mine roadways", which has the following characteristics: 1. Protection of various underground roadways: Inorganic surface spraying protective materials that ensure the safety of the tunnel environment and the health of workers, and reduce the accident rate.

[0039] 2. Various underground tunnels are isolated from bacteria and other contaminants: A multifunctional nano-inorganic safety and health protection material that isolates toxic and harmful gases, prevents the spread of bacteria, fungi, and mold on the surface of tunnels, and ensures the safety of underground air.

[0040] This multi-functional material integrates protection, pollution prevention, and illumination. It is widely used for surface coating protection of coal seams, rock masses, chambers, and shotcrete surfaces in all coal mine roadways. It effectively addresses the hazardous factors in the complex physical, chemical, and biological environments of underground coal mines, providing protection for the health and safety of coal miners. It is of great significance for standardizing the quality of underground coal mine construction and building safe mines.

[0041] Example 2 Based on Example 1, such as Figure 1-7As shown, a mining HBK special structure auxiliary treatment material spraying system uses the mining HBK special structure auxiliary treatment material of Example 1. It includes a displacement vehicle 1 and a paint spraying head 2. The feed end of the paint spraying head 2 is equipped with a dual alternating gas-liquid mixing paint spraying mechanism 3. The dual alternating gas-liquid mixing paint spraying mechanism includes a first spraying component 4 and a second spraying component 5 that alternately feed materials, and a crankshaft 7 for driving the first spraying component 4 and the second spraying component 5. The crankshaft 7 is rotated by a drive component 6. Currently, the concrete (dry and wet) shotcrete machines used in coal mines and roadway construction are all rotor disc shotcrete machines. This type of shotcrete machine has four major disadvantages: First, the rotor disc is not tightly sealed at the top and bottom, resulting in a large amount of dust being sprayed out during operation, creating an extremely poor working environment; this work is even considered one of the ten dirtiest jobs in the world. Second, it consumes a lot of energy; in addition to the power required for compressed air, a 5-10 kW motor is needed to drive the rotor disc. Third, each machine requires at least 3-4 people to operate, resulting in low efficiency. Fourth, the equipment is bulky, expensive, has a short service life, requires frequent maintenance, and has high construction costs. This invention, by setting a driving component, which is a motor, drives the crankshaft to rotate, thereby realizing the alternating feeding of the first spraying component 4 and the second spraying component 5. It has the advantages of good sealing, energy saving, low cost, long service life and low maintenance cost, and is especially suitable for the wet coating material of this invention that is mixed with water.

[0042] The first injection component 4 includes a first cylinder 41, a crankshaft 7 located at one end inside the first cylinder, a first bearing 42 coaxially connected to the crankshaft, a first connecting rod 43 connected to the outer wall of the first bearing, a first push rod 44 hinged to the other end of the first connecting rod, a first piston block 45 connected to the other end of the first push rod, the first piston block being movable along the length direction inside the first cylinder, a first feed port 46 and a first air inlet 48 provided on one side of the first cylinder away from the crankshaft, a first injection port 47 provided on the end face of the first cylinder away from the crankshaft, a first one-way inlet valve 11 provided at the first feed port, a first one-way outlet valve 12 provided at the first injection port, and a second one-way inlet valve 13 provided at the first air inlet. The rotation of the crankshaft drives the first connecting rod, the first push rod, and the first piston block to move up and down along the length of the first cylinder. When the first piston block moves upward, the volume of the air chamber below the first piston block increases and the pressure decreases, which closes the first one-way outlet valve 12 and opens the first one-way inlet valve 11 and the second one-way inlet valve 13, allowing the paint and outside air to enter the air chamber. When the first piston block moves downward, the volume of the air chamber below the first piston block decreases and the pressure increases, which closes the first one-way inlet valve 11 and the second one-way inlet valve 13 and opens the first one-way outlet valve 12, pushing the mixed paint and gas inside the air chamber into the first spray port 47 at high speed to achieve paint spraying.

[0043] Further, the second injection component 5 includes a second cylinder 51, which is arranged side-by-side with the first cylinder on the side away from the first feed inlet. The crankshaft 7 is located at one end inside the second cylinder, and a second bearing 52 is coaxially connected to the crankshaft. A second connecting rod 53 is connected to the outer wall of the second bearing. A second push rod 54 is hinged to the other end of the second connecting rod, and a second piston block 55 is connected to the other end of the second push rod. The second piston block can move along the length direction inside the second cylinder. A second feed inlet 56 and a second air inlet 58 are provided on the side of the second cylinder away from the first cylinder. The second feed inlet 56 and the second air inlet 58 are located at the end of the second cylinder away from the crankshaft. A second injection port 57 is provided on the end face of the second cylinder away from the crankshaft. A third one-way valve 14 is provided at the second feed inlet, a second one-way valve 15 is provided at the second injection port, and a fourth one-way valve 16 is provided at the second air inlet. The rotation of the crankshaft drives the second connecting rod, the second push rod, and the second piston block to move up and down along the length of the second cylinder. When the second piston block moves upward, the first piston block moves downward, the volume of the air chamber below the second piston block increases, and the pressure decreases, which closes the second one-way outlet valve and opens the third and fourth one-way inlet valves, allowing paint and outside air to enter the air chamber. When the second piston block moves downward, the first piston block moves upward, the volume of the air chamber below the second piston block decreases, and the pressure increases, which closes the third and fourth one-way inlet valves and opens the second one-way outlet valve, pushing the mixed paint and gas inside the air chamber into the second spray port at high speed. This alternating operation achieves paint spraying.

[0044] The first spray nozzle 47 and the second spray nozzle 57 are connected to a three-way connector 17. The output end of the three-way connector is connected to the feed end of the paint spray head 2 through a feeding hose 18.

[0045] The dual alternating gas-liquid mixing coating spraying mechanism further includes a first quantitative gas supply component 8 and a second quantitative gas supply component 9 that alternately and quantitatively supply gas to the inside of the first cylinder and the second cylinder. The first quantitative gas supply component 8 is located on the side of the first cylinder away from the second cylinder, and the second quantitative gas supply component 9 is located on the side of the second cylinder away from the first cylinder.

[0046] The first metered gas supply component 8 includes a third cylinder 81. A crankshaft 7 is located at one end inside the third cylinder. A third bearing 82 is coaxially connected to the crankshaft. A third connecting rod 83 is connected to the outer wall of the third bearing. A third push rod 84 is hinged to the other end of the third connecting rod. A third piston block 85 is connected to the other end of the third push rod. The third piston block can move along the length direction inside the third cylinder. A first air outlet 86 connected to the first air inlet is provided on one side of the third cylinder near the first cylinder. A third air inlet 87 is provided on the other side of the third cylinder. A fifth one-way valve 19 is provided at the third air inlet. The rotation of the crankshaft drives the third connecting rod, the third push rod, and the third piston block to move up and down along their length inside the third cylinder. When the third piston block moves upward, the first piston block moves downward, the volume of the air chamber below the third piston block increases, and the pressure decreases, which closes the second one-way valve and opens the fifth one-way valve, allowing outside air to enter the air chamber. When the third piston block moves downward, the first piston block moves upward, the volume of the air chamber below the third piston block decreases, and the pressure increases, which closes the fifth one-way valve and opens the second one-way valve, sending a metered amount of gas from the air chamber of the third cylinder into the first cylinder to mix with the coating.

[0047] The second quantitative gas supply component 9 includes a fourth cylinder 91. The crankshaft 7 is located at one end inside the fourth cylinder. A fourth bearing 92 is coaxially connected to the crankshaft. A fourth connecting rod 93 is connected to the outer wall of the fourth bearing. A fourth push rod 94 is hinged to the other end of the fourth connecting rod. A fourth piston block 95 is connected to the other end of the fourth push rod. The fourth piston block can move along the length direction inside the fourth cylinder. A second air outlet 96 connected to the second air inlet is provided on one side of the fourth cylinder near the second cylinder. A fourth air inlet 97 is provided on the other side of the fourth cylinder. A sixth one-way valve 20 is provided at the fourth air inlet. The rotation of the crankshaft drives the fourth connecting rod, the fourth push rod, and the fourth piston block to move up and down along their length inside the fourth cylinder. When the fourth piston block moves upward, the second piston block moves downward, the volume of the air chamber below the fourth piston block increases, and the pressure decreases, which closes the fourth one-way valve and opens the sixth one-way valve, allowing outside air to enter the air chamber. When the fourth piston block moves downward, the second piston block moves upward, the volume of the air chamber below the fourth piston block decreases, and the pressure increases, which closes the sixth one-way valve and opens the fourth one-way valve, sending a metered amount of gas from the air chamber of the fourth cylinder into the second cylinder to mix with the coating.

[0048] The third cylinder 81 and the fourth cylinder 91 have the same internal volume, and the first cylinder and the second cylinder have the same internal volume. The internal volumes of the third cylinder 81 and the fourth cylinder 91 are smaller than the internal volumes of the first cylinder and the second cylinder. This design allows for the metered delivery of air into the first and second cylinders each time, ensuring the correct mixing ratio of paint and gas, and further improving the paint spraying effect.

[0049] The displacement vehicle 1 has a placement cavity inside, and a paint holding and mixing tank is placed inside the placement cavity. The paint holding and mixing tank includes a tank body, and a stirring shaft is coaxially arranged inside the tank body. The upper and lower ends of the stirring shaft are respectively connected to the upper and lower end faces of the tank body through bearings. The upper end face of the tank body is provided with a first motor for driving the stirring shaft to rotate and a feeding hopper for putting in paint. The stirring shaft is provided with a plurality of stirring teeth along its axial direction, and the inner wall of the tank body is also provided with a first discharge pipe and a second discharge pipe along its height direction. The first inlet 46 is connected to the upper end of the first discharge pipe through the first inlet pipe 21, and the second inlet 56 is connected to the upper end of the second discharge pipe through the second inlet pipe 22.

[0050] The upper surface of the displacement vehicle 1 is also equipped with a semi-automatic spraying mechanism 10. The semi-automatic spraying mechanism 10 includes two vertically arranged vertical plates 101. An arc-shaped elastic locking sleeve 102 for locking the paint spraying head 2 is arranged between the upper ends of the two vertical plates 101. Movable rods 103 are arranged horizontally at the left and right ends of the arc-shaped elastic locking sleeve 102, respectively. The other end of the movable rod is connected to the two vertical plates 101 through bearings. One of the vertical plates is also equipped with a forward and reverse motor 104 for rotating the movable rod. The forward and reverse motor 104 is controlled by a control panel or wirelessly. The rotation of the forward and reverse motor 104 can drive the arc-shaped elastic locking sleeve 102 and the paint spraying head 2 to swing up or down, thereby realizing semi-automatic spraying of the paint spraying head 2 without manual operation and with uniform paint application.
