Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] According to an embodiment of this utility model, an integrated fire prevention injection device is provided. Please refer to [link / reference]. Figures 1 to 4The system includes: a housing 1, which is hollow inside and divided into two independently configured mixing chambers 2, each of which has a feed inlet 23 and a water inlet 24 on the housing 1. A stirring device 3 is installed in the mixing chamber 2 for stirring the mixed materials. The mixing chamber 2 includes at least two mixing chambers 4; and a grouting pump 5, which has at least two suction ports connected to the discharge ports 25 of the mixing chambers 2. The mixing chamber 4 includes at least two discharge ports 41 on the housing 1, and both discharge ports 41 are connected to the mixer.

[0027] Through the above-mentioned design, the fire prevention injection device is integrated into a single unit. This device integrates batching, mixing, and injection, and is pre-configured with internal connecting pipes and connection ports such as the material inlet 23 and water inlet 24. The internal piping is complete, and only the slurry, water pipe, and air duct need to be connected before use, which simplifies the installation and removal process, facilitates the handling of the device, enables rapid installation and removal, improves construction efficiency, and effectively solves the problems of dirt and disorder and low standards at the injection site. It also solves the technical problem of inconvenient handling and installation caused by the large number of containers and supporting facilities in fire prevention injection devices in related technologies.

[0028] In some embodiments, the mixer is located outside the housing 1 and is connected to at least two mixing chamber outlets 41 respectively. The mixing materials from multiple mixing chambers 2 are mixed in the mixer to prevent the mixing time of the mixing materials from being too long, which would cause the slurry to solidify prematurely and affect the grouting effect.

[0029] In some embodiments, the container 1 is made of stainless steel, which has better corrosion resistance and overall lightness than the mixing barrel. The stainless steel container is resistant to compression deformation, can be recycled, and avoids the problem of frequent deformation and damage during the transportation of the mixing barrel, thus achieving material savings.

[0030] In some embodiments, the mixing chamber 4 is provided with a maintenance cover, which is detachably connected to the housing 1. After the maintenance cover is opened, the grouting pump 5 can be removed separately for maintenance.

[0031] In the integrated fire prevention injection device of this embodiment, see... Figure 4 The housing 1 is equipped with a first partition 11. A mixing chamber 4 is provided on one side of the first partition 11, and at least two mixing chambers 2 are provided on the other side of the first partition 11. Through the above arrangement, multiple closed and independent chambers are formed inside the housing 1, ensuring the continuity and convenience between various process steps.

[0032] In the integrated fire prevention injection device of this embodiment, see... Figure 4At least two mixing chambers 2 include a first mixing chamber 21 and a second mixing chamber 22 spaced apart. A second partition 12 is provided between the first mixing chamber 21 and the second mixing chamber 22. One end of the second partition 12 is connected to the first partition 11, and the extending direction of the second partition 12 is perpendicular to the first partition 11. By setting the second partition 12, the first mixing chamber 21 and the second mixing chamber 22 are formed inside the housing 1, maximizing the volume of each mixing chamber and improving the material mixing efficiency.

[0033] In the integrated fire prevention injection device of this embodiment, see... Figure 1 or Figure 4 The mixing chamber outlet 25 includes a first mixing chamber outlet 251 and a second mixing chamber outlet 252 located at the bottom of the first partition 11. The first mixing chamber outlet 251 is correspondingly arranged to the first mixing chamber 21, and the second mixing chamber outlet 252 is correspondingly arranged to the second mixing chamber 22. By setting the first mixing chamber outlet 251 and the second mixing chamber outlet 252, the mixed material in the first mixing chamber 21 is sucked out by the grouting pump 5 through the first mixing chamber outlet 251, and the mixed material in the second mixing chamber 22 is sucked out by the grouting pump 5 through the second mixing chamber outlet 252. Setting the first mixing chamber outlet 251 and the second mixing chamber outlet 252 at the bottom of the first partition 11 can improve the outflow efficiency of the mixed material and avoid the accumulation of the mixed material.

[0034] In the integrated fire prevention injection device of this embodiment, see... Figure 1 The integrated fire prevention injection device includes lifting rings 6 installed on the top of the housing 1. The lifting rings 6 are used to move the housing 1. Multiple lifting rings 6 are symmetrically arranged on opposite sides of the housing 1. The lifting rings 6 facilitate the overall lifting and transportation of the device, allowing for rapid installation and removal within the tunnel via rail transport equipment.

[0035] In some embodiments, the housing 1 has a cuboid structure, and the lifting rings 6 include 4 rings, which are located at the four corners of the top plate of the housing 1.

[0036] In the integrated fire prevention injection device of this embodiment, see... Figure 1 The mixing device 3 includes a mixer 31 and a mounting base 32 for mounting the mixer 31. The mounting base 32 is mounted on the top of the housing 1 and is detachably connected to the housing 1. Through this design, the mixing device 3 adopts a modular approach. After removing the mounting base 32, it can be pulled out entirely for inspection and maintenance, facilitating the complete removal of the mixing device 3 for easy installation or maintenance. Placing the mixer inside the housing 1 ensures the safety of construction personnel.

[0037] In some embodiments, the stirring device 3 includes a pneumatic motor for driving the rod stirrer 31, which enables automatic stirring after feeding, and the stirring speed can be controlled by airflow.

[0038] In the integrated fire prevention injection device of this embodiment, see... Figure 1 The feed inlet 23 includes: a liquid inlet 231, which is used to input liquid raw materials into the first mixing chamber 21 or the second mixing chamber 22, and the liquid inlet 231 is located at the top of the housing 1; and a feed port 232, which is used to input solid raw materials into the first mixing chamber 21 or the second mixing chamber 22, and the feed port 232 is located at the top of the housing 1. Specifically, a pipe interface is provided at the liquid inlet 231 to facilitate connection with a pipe for conveying raw materials.

[0039] In some embodiments, the stirring device 3 is spaced a certain distance from the feeding port 232 to ensure the safety of the feeding personnel and avoid further injury to the feeding personnel in the event of accidents such as personnel falling.

[0040] In the integrated fire prevention injection device of this embodiment, see... Figure 1 The feeding port 232 is equipped with a cover, which is detachably connected to the top of the box 1. By providing the cover, the cover can be closed when no material is being added, preventing debris from entering the box and ensuring that the mixing chamber 2 remains clean.

[0041] In the integrated fire prevention injection device of this embodiment, see... Figure 1 The first mixing chamber 21 and / or the second mixing chamber 22 include a cleaning port 7. The cleaning port 7 is located on the side of the first mixing chamber 21 and / or the second mixing chamber 22 away from the first partition 11. The cleaning port 7 is used to drain the cleaning water after cleaning the first mixing chamber 21 and / or the second mixing chamber 22. By providing the cleaning port 7, the cleaning effect is improved in conjunction with the agitator, and it is convenient to clean the tank 1 after use. At the same time, the discharge of liquid will not cause water overflow and cause scouring and pollution of the tunnel.

[0042] In the integrated fire prevention injection device of this embodiment, see... Figure 1 The mixing chamber 4 includes an air inlet 42, which is located on the housing 1. A filter screen is installed at the air inlet 42, which is used to input air into the mixing chamber 4. By providing the air inlet 42, air is supplied for the piston movement of the grouting pump 5, ensuring the normal operation of the grouting pump 5.

[0043] It should be noted that the grouting pump 5 is a double-suction grouting pump with two suction ports and two output ports connected to the two suction ports. The two output ports of the grouting pump 5 are respectively connected to the two mixing chamber outlets 41 through hoses. The two mixed materials output through the mixing chamber outlets 41 are mixed in the mixer outside the box 1, and then the grouting is completed.

[0044] In some embodiments, the grouting process is as follows: according to the required gelling time on site, the base material A (water glass) and the coagulant B (baking soda) are stirred and diluted evenly in different mixing chambers in proportion. The specific gravity of liquid A (water glass solution) is preferably 1.13-1.15, and the specific gravity of liquid B (coagulant solution) is preferably 1.07-1.11. Then, the grouting pump 5 is turned on, and liquid A and liquid B are extracted by the double-suction grouting pump and mixed in the mixer. After mixing, they are transported to the grouting borehole by the grouting pipe. The gelling time is adjusted to ensure minimal leakage and good filling effect in the floating coal.

[0045] In some embodiments, this integrated fire prevention injection device can also be used for injection of infinitely variable filling materials for sealed roadways, enabling remote bag filling. Two powders, A and B, are stirred separately to form a uniform slurry. The uniform slurry is then injected via a dual-suction injection pump, with equal amounts fed into a mixer through two delivery pipes for mixing. After thorough mixing in the mixer, the two slurries (A and B) are fed together into the filling bag or empty roadway, where they quickly solidify.

[0046] In this embodiment of the integrated fire prevention injection device, a stainless steel double-box body replaces the mixing tank, and the injection pump 5, mixer 31, etc. are installed inside the box body 1. The main piping system is built-in, forming a complete injection system. This facilitates overall movement, rapid installation and removal, and efficient construction, effectively solving problems such as messy and unsanitary conditions and low standards at the injection site. After on-site promotion and application, this device has advantages such as a clean appearance, small footprint, convenient maintenance, simple use, and easy installation and removal. In this embodiment, the integrated fire prevention injection device, after practical application, reduced the number of workers required from four to only two, demonstrating good on-site application results, effectively reducing the labor intensity of workers and ensuring safe construction.
