Description

Technical Field

[0001] This utility model relates to the technical field of fireproof material filling equipment, and in particular to a fireproof isolation material filling equipment for underground mines. Background Technology

[0002] During coal mining, in coal seams, roadways, and areas affected by geological structures, the roof stability is poor, and roof collapses are common, forming high-risk areas in roadways and mining areas. The long-term existence of these high-risk areas poses safety hazards to coal mine production. In recent years, with the widespread adoption of fully mechanized longwall mining technology and increased mine depth, mine pressure has become more severe and frequent, and the thickness of coal roofs in roadways has increased significantly. Due to these reasons, high-risk areas are prevalent in modern mines, leading to a sharp increase in the risk of spontaneous combustion of coal roofs in roadways. Potential hazards such as gas accumulation in high-risk areas constantly affect mine safety. Based on these circumstances, the treatment of high-risk areas is particularly necessary to ensure safe production. With increasing emphasis on high-risk area treatment, various methods and materials for treating high-risk areas have emerged both domestically and internationally. Different materials require different equipment; currently, high-risk area treatment equipment is generally divided into grouting equipment and filling equipment.

[0003] Three-phase foam is a common fireproof filling material used in underground coal mines. It consists of three phases: mud (or fly ash slurry), foaming agent, and gas (nitrogen or air). In use, the material is mixed evenly in a mixer and then pumped to the filling equipment at the front of the working face, where it is sprayed out. However, existing filling equipment is generally large, making it unsuitable for use in confined spaces.

[0004] Therefore, it is necessary to provide a downhole fireproof isolation material filling device to solve the above-mentioned technical problems. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a downhole fireproof isolation material filling device that can fill fireproof material on the working surface and is suitable for use in narrow areas.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments. Example

[0016] like Figure 1-6 As shown, the downhole fireproof isolation material filling equipment provided by this utility model includes: a support frame 1, a rotating bracket 2 mounted on the support frame 1, a jet pipe 3 with adjustable pitch angle rotatably mounted on the rotating bracket 2, a material connection port 4 at the tail end of the jet pipe 3, a high-pressure gas inlet 5 inclined at the bottom of the jet pipe 3, an arc-shaped handle 8 installed near the tail end of the jet pipe 3, a booster pump 6 mounted on the rotating bracket 2, a hose 7 installed between the booster pump 6 and the high-pressure gas inlet 5, and the material connection port 4 connected to a delivery pump for feeding the mixed fireproof material from the tail end into the jet pipe 3. In use, the equipment is placed on the working surface, the arc-shaped handle 8 is held, and the fireproof material enters the jet pipe 3 from the material connection port 4 and then moves towards the front end of the jet nozzle 3. Simultaneously, the booster pump 6 sends high-pressure air through the hose 7 and the high-pressure gas inlet 5 into the jet pipe 3. After the gas mixes with the material in the pipe, it is ejected from the jet nozzle 3, spraying the fireproof material onto the working surface. Pressing down the curved handle 4 adjusts the material spray direction, and rotating it horizontally adjusts the orientation of the spray pipe 3. The device has a compact overall structure and small size, making it suitable for use in confined spaces. Furthermore, the curved handle 4 design ensures that both hands are comfortably positioned when adjusting the elevation angle of the spray pipe 3, preventing hand discomfort and improving user comfort.

[0017] By setting up a support frame 1, a rotating bracket 2, a spray pipe 3, a booster pump 6, and an arc-shaped handle 8, and installing the booster pump 6 on the rotating bracket 2, fireproof material can be easily filled onto the working surface. The overall structure of the device is simple and compact, making it suitable for use in narrow areas. Example

[0018] like Figure 2-3As shown, in this embodiment, a rotating shaft 9 is fixedly installed at the bottom of the rotating bracket 2, and a sleeve 10 is rotatably installed at the bottom end of the rotating shaft 9 through a bearing. A plug-in rod 11 is fixedly installed at the top of the support frame 1, and the plug-in rod 11 is inserted into the sleeve 10, so that the rotating bracket 2 and the support frame 1 can be quickly assembled and disassembled for transportation.

[0019] By setting the rotating shaft 9, sleeve 10, and plug rod 11, the rotating bracket 2 and the support frame 1 can be easily assembled. Example

[0020] like Figure 1-3 As shown, a support plate 12 is fixedly installed at the bottom of the support frame 1. The support plate 12 increases the ground contact area of ​​the support frame 1, making the equipment less likely to sink into the ground and improving the stability of the equipment. At the same time, the larger area makes the equipment easier to drag and move on gravel surfaces.

[0021] By fixing the support plate 12 to the bottom of the support frame 1, the stability of the equipment can be improved and the equipment can be moved more easily. Example

[0022] like Figure 5-6 As shown, an auxiliary plate 13 is hinged to the bottom of the support plate 12. After the auxiliary plate 13 is rotated 180 degrees outward, it is parallel to the bottom of the support plate 12, which further increases the support area of ​​the equipment and improves the stability of the equipment. Moreover, after the auxiliary plate 13 is folded into the bottom of the support plate 12, the overall volume of the equipment will not be too large, which facilitates transportation.

[0023] By hinged installation of auxiliary plate 13 at the bottom of support plate 12, the stability of the equipment can be further improved. Example

[0024] like Figure 4-5 As shown, in this embodiment, auxiliary handles 14 are installed on both sides of the spray pipe 3. The auxiliary handles 14 are fixed to the rotation axis of the spray pipe 3. When in use, the personnel can stand on the side (e.g., the top of the support plate 12 or the auxiliary plate 13), hold the auxiliary handles 14, and adjust the pitch angle of the spray pipe 3.

[0025] By installing auxiliary handles 14 on both sides of the jet pipe 3, the pitch angle of the jet pipe 3 can be easily adjusted from the side. Example

[0026] like Figure 2-3 As shown, arc-shaped guide heads 15 are inclined on both sides of the support plate 12. The guide heads 15 are inclined upward at a certain angle. When the equipment is being dragged, the guide heads 15 will not be blocked by the gravel when they encounter it, but will slide along the top of the gravel, thus improving the equipment's passability.

[0027] By setting arc-shaped guide heads 15 at an angle on both sides of the support plate 12, the passability of the equipment can be improved.

[0028] Working Principle: During use, place the device on the work surface, grasp the handle 8, and the fireproof material enters the spray pipe 3 through the material connection port 4, then moves towards the front end of the spray nozzle 3. Simultaneously, the booster pump 6 sends high-pressure air through the hose 7 and high-pressure gas inlet 5 into the spray pipe 3. After the gas mixes with the material inside the pipe, it is then sprayed out at high speed from the outlet 3, spraying the fireproof material onto the work surface. Pressing down the arc-shaped handle 4 adjusts the spray direction, and rotating it horizontally adjusts the horizontal orientation of the spray pipe 3. The device has a compact overall structure and small size, making it suitable for use in confined spaces.
