Description

Technical Field

[0001] This utility model belongs to the field of fire prevention, dust suppression and spraying technology, specifically a fire prevention, dust suppression and spraying device. Background Technology

[0002] Due to the special working conditions, mine fires are difficult to effectively control, especially the spontaneous combustion of coal seams in the shutdown line of the working face, which is highly concealed. It is difficult to implement fire prevention and extinguishing measures in the support space of the shutdown line and the goaf behind the support, especially in areas with small or no support gaps. It is very time-consuming, requires a lot of manpower, material resources, and financial resources. Traditional methods such as grouting, injection of sizing agents, and injection of liquid carbon dioxide cannot reach the location of the hidden danger.

[0003] Commonly used fire extinguishing agents both domestically and internationally include foam, dry powder, water, inert gas, and aerosols. Among these, aerosols are more effective at extinguishing fires than the other methods.

[0004] Meanwhile, application number CN110613909B, entitled "A Pneumatic Fire Extinguishing Material Spraying and Gel-Making Device," describes a pneumatic fire extinguishing material spraying and gel-making device that includes a powder spraying system and a water spraying system. The powder spraying system includes a pneumatic powder diaphragm pump equipped with a powder dispensing control valve and a powder dispensing spray gun. The water spraying system includes a water volume control box with an external multi-parameter detector for detecting toxic and harmful gases and a spray gun. The powder spraying system sprays fire extinguishing powder through the powder dispensing spray gun, while the water spraying system sprays water through the spray gun. When the fire extinguishing powder and water meet, they can form a gel. This gel, when applied to the surface of the coal, can isolate oxygen and prevent reignition. It integrates powder spraying, adhesive preparation, dust suppression, and cooling, and enables adjustable and controllable water spraying and powder output. At the same time, it monitors the gas concentration in the working environment through a multi-parameter measuring device and provides automatic audible and visual alarms to ensure operational safety. It solves the problem of rapid treatment of coal fire source hazards under special working conditions in coal mines and has extremely high practicality, pertinence, and emergency needs.

[0005] The above-mentioned technical solution, during use, only allows the fire extinguishing material spraying device to spray powder.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 4 As shown, this utility model provides a fire prevention, dust suppression spraying device, including a mixing tank 1, a mixer 12 installed on the surface of the mixing tank 1, and a double-pass assembly 2 installed on the surface of the mixing tank 1.

[0026] The dual-channel assembly 2 includes a partition 21. The partition 21 is installed inside the mixing tank 1. The bottom of the mixing tank 1 is connected to a partition pipe 22. The surface of the partition pipe 22 is connected to an A-channel pipe 23 and a B-channel pipe 24, respectively. Switch valves 25 are installed on the surface of both the A-channel pipe 23 and the B-channel pipe 24. One end of the partition pipe 22 is connected to an air pipe 26. A partition 27 is installed inside the partition pipe 22. Switch valve 211 is installed on the surface of the air pipe 26. A closing assembly 3 is installed on the surface of the mixing tank 1, thereby enabling the spraying of liquid on one side and powder on the other side, and enabling the spraying of liquid or powder on both sides, further improving the application range of the fire prevention, dust suppression and extinguishing spraying device and reducing the limitations of spraying.

[0027] Specifically, the mixing tank 1 is symmetrically equipped with inclined discs 28, and the surface of the inclined discs 28 has a discharge hole 29, which can guide the fire extinguishing material to flow into the discharge hole 29 and enter the interior of the partition tube 22.

[0028] like Figures 1 to 4 As shown, a discharge pipe 210 is connected to the discharge hole 29. Both discharge pipes 210 are connected to the partition pipe 22, which enables the fire extinguishing material to be guided into the two cavities separated by the partition pipe 22.

[0029] Furthermore, the two discharge pipes 210 are located in the two discharge cavities of the partition pipe 22, which allows the fire extinguishing material to enter the two cavities separated by the partition pipe 22 respectively.

[0030] It is worth noting that pipe A 23 and pipe B 24 are respectively connected to the two discharge cavities of the partition pipe 22, and pipe A 23 and pipe B 24 are located on both sides of the partition pipe 22, thus enabling the simultaneous spraying of liquid and powder.

[0031] like Figures 1 to 4 As shown, the closing assembly 3 includes an opening and closing plate 31. The opening and closing plate 31 is provided inside the mixing tank 1. An adjustment groove 32 adapted to the opening and closing plate 31 is provided on the surface of the partition 21. The opening and closing plate 31 and the partition 21 are slidably connected through the adjustment groove 32. A pull rod 33 is installed on the surface of the opening and closing plate 31. One end of the pull rod 33 passes through the partition 21 and the mixing tank 1 in sequence and extends to the outside of the mixing tank 1, so as to facilitate the mixing of fire extinguishing materials, so that the two states of fire extinguishing materials can be separated and mixed, further improving the use effect of the device and making it convenient for operators to use.

[0032] It is worth emphasizing that a return spring 34 is fitted on the surface of one end of the pull rod 33 that passes through the mixing tank 1. One end of the return spring 34 is connected to the mixing tank 1, and the other end of the return spring 34 is connected to the pull rod 33, so that the pull rod 33 can be reset, which is convenient for operators to use.

[0033] The structure of the electric motor is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0034] Working principle and process: When spraying liquid and powdered fire extinguishing materials, firstly, the powdered fire extinguishing material is poured into the mixing tank 1. Since the mixing tank 1 has a partition 21 installed inside, the fire extinguishing material is divided into two parts. Then, water is poured into another cavity, and the mixer 12 is started to stir the fire extinguishing material inside, ensuring thorough mixing of the fire extinguishing material and water. At this point, one side of the mixing tank 1 contains the liquid fire extinguishing material, and the other side contains the powdered fire extinguishing material. Then, the valve 211 is opened, allowing air to enter the mixing tank 1 through the air pipe 26. The liquid and powdered fire extinguishing materials then flow through the openings on the surfaces of the two inclined plates 28. The material enters the discharge pipe 210 through the discharge hole 29. At this time, the discharge pipe 210 guides the liquid and powdered fire extinguishing materials, causing them to fall into the partition pipe 22. The partition plate 27 installed inside the partition pipe 22 separates the liquid and powdered fire extinguishing materials. Then, the switch valve 25 is opened, and the liquid and powdered fire extinguishing materials are discharged from the A-pipe 23 and B-pipe 24 respectively. This allows for spraying liquid on one side and powder on the other, and both sides can be sprayed with either liquid or powder, further improving the application range of the fire extinguishing material spraying material and reducing the limitation of the spraying range.

[0035] When the fire extinguishing material is poured into the mixing tank 1, the pull rod 33 is pulled. The pull rod 33 slides on the surface of the mixing tank 1. When the pull rod 33 is pulled, it causes the return spring 34 to deform, and the return spring 34 can reset the position of the pull rod 33, making it convenient for the operator to use. At this time, the pull rod 33 pulls the opening and closing plate 31 to slide in the adjustment groove 32 opened on the surface of the partition plate 21, so that the opening and closing plate 31 moves upward. During the upward movement, the distance between the opening and closing plate 31 and the mixing tank 1 gradually increases. At this time, the partition plate 21 in the mixing tank 1 connects the two cavities that are separated, so that the fire extinguishing material in the two cavities can be connected, so that liquid or powder can be sprayed from both sides. At this time, the operator releases the pull rod 33, and the return spring 34 is no longer pulled, so the opening and closing plate 31 is reset, so that the two cavities separated by the partition plate 21 are separated, thus forming a separate closed space, which can achieve the spraying of liquid on one side and powder on the other side.

[0036] It should be noted that the mixing tank 1 and mixer 12 in this device are model ZBQ-27 / 1.5 grouting pump (equipped with a 100L mixing tank + 60 mixer).

[0037] It should be noted that: the pressure boosting flow ratio of materials A and B is 1:1; the viscosity range of materials A and B is 200-1000 cp; the output of materials A and B is 3-15 kg / min; the working air pressure is 0.3-0.8 MPa; the maximum force of a single-component liquid is 5-15 MPa; the weight is 60 kg; the valve inner diameter thread is 1 / 8 (one-point thread); the inner diameter of the main material pipe is 10 mm; and the outer diameter of the air pipe is 10 mm.
