Description

Technical Field

[0001] The utility model belongs to the field of fire safety equipment in production workshops, and particularly relates to a fire-fighting device. Background Art

[0002] In current glue production workshops, flammable gases that may be produced during glue production include tert-butyl alcohol, toluene, methylcyclohexane, gasoline, acrylic acid, and epoxy resin. These substances are not only hazardous chemicals, but can also pose a threat to the human body when volatilized.

[0003] These gases can cause fires during the production process, and combustion also produces toxic gases such as carbon monoxide and sulfur dioxide, which pose a serious threat to human health. Therefore, strict safety measures must be taken during the glue production process, including storage in a cool, well-ventilated area, away from fire and heat sources, and the provision of necessary personal protective equipment and fire-fighting equipment. However, each workshop environment is different, and it is difficult to achieve good ventilation conditions in every workshop. Once these gases accumulate to a certain level, they can easily ignite when exposed to open flames. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a fire-fighting device. By arranging the ventilation seat at the lower end of the storage tank, and the air intake plate on the ventilation seat is parallel to the outer wall of the storage tank, when negative pressure air is introduced, the air around the storage tank can be sucked in, thereby changing the concentration of the gas around the storage tank and reducing the possibility of combustion. By controlling the distance between the air intake plate and the storage tank, the speed of air intake can be effectively increased, and rapid ventilation can be achieved. This device is particularly suitable for additional installation in workshops with poor ventilation conditions.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A fire-fighting device comprises a frame, a storage tank and a fire-fighting component, wherein the storage tank is arranged on the frame, and the fire-fighting component comprises a ventilation seat and a ventilation pipe, the ventilation seat is arranged on the frame, one end of the ventilation pipe is connected to the air inlet pipe at the lower end of the ventilation seat, and the other end of the ventilation pipe is connected to a vacuum pump, and the suction plate at the upper end of the ventilation seat faces the storage tank, and the upper end surface of the suction plate is provided with a suction hole connected to the ventilation pipe, and a gap is left between the suction hole and the storage tank; the upper end surface of the suction plate is an arc-shaped structure parallel to the outer side wall of the storage tank, and the distance between the upper end surface of the suction plate and the storage tank is 10-20mm; the ventilation seat comprises several groups, and several groups of the ventilation seats are arranged in parallel under the storage tank, and the ventilation pipe is respectively connected to several groups of ventilation seats.

[0007] The fire-fighting device adopts this structure, and the frame can be a frame-like structure formed by welding a combination of square pipes. The storage tank is arranged on the frame, and the connection part between the storage tank and the frame is placed horizontally on the square pipe. There can be multiple sets of connecting bases, so there is a gap between the storage tank and the frame. By adding a fire-fighting component that can inhale air at the lower end of the storage tank, that is, a ventilation seat, the replacement of the air around the storage tank can be achieved. In order to better achieve air inhalation, an air intake plate is provided on the upper end of the ventilation seat. The air intake plate has an arc-shaped structure and keeps a distance from the bottom of the storage tank and is parallel to each other. The air intake holes provided on the air intake plate are connected to the ventilation pipe connected to the air inlet pipe at the lower end of the ventilation seat. Therefore, when the vacuum pump connected to the ventilation pipe is vacuumed, air will be inhaled from the gap between the air intake plate and the storage tank, thereby changing the air concentration at the lower end of the storage tank. In order to accelerate the flow of air, the air intake plate and The distance between the storage tank is kept between 10-20mm. If it is less than 10mm, the distance between the suction plate and the storage tank is too small, which will cause the suction space to become smaller and fail to achieve sufficient air suction. When the distance exceeds 20mm, it is unable to achieve a good effect of improving the air circulation speed. Therefore, the air suction volume and suction speed are best when it is between 10-20mm. Since the connection between the storage tank and the rack is fixed by multiple sets of connecting bases, in order to better achieve the air replacement effect around the storage tank, multiple sets of ventilation seats can be set up. Each set of ventilation seats is arranged in parallel under the storage tank and is connected to the same set of ventilation pipes. Since this type of ventilation does not require a large replacement volume, a set of vacuum pumps can achieve air ventilation, reduce the concentration around the storage tank, and make the gas concentration not reach the combustion conditions, thereby achieving fire safety and ensuring the protection of the workshop during the glue production process.

[0008] Furthermore, a nitrogen concentration sensor is provided on the lower end surface of the air intake plate.

[0009] Compared with the existing technology, the advantages of the present invention are: the arc-shaped structure of the air suction plate keeps a distance from the bottom of the storage tank and is parallel to each other, so that under the action of the vacuum pump, the air at the lower end of the storage tank is replaced. When the distance is between 10-20 mm, the air flow rate and flow rate that can be circulated can be improved. Therefore, under the action of a small vacuum pump, air ventilation can be achieved, and the concentration around the storage tank can be reduced so that the gas concentration does not reach the conditions for combustion, thereby achieving fire safety and ensuring the protection of the workshop during the glue production process.

An air intake hole 313 connected to the ventilation pipe 32 is provided on the end face, and a gap is left between the air intake hole 313 and the storage tank 2; the upper end face of the air intake plate 312 is an arc-shaped structure parallel to the outer side wall of the storage tank 2, and the distance between the upper end face of the air intake plate 312 and the storage tank 2 is 10-20mm; the ventilation seat 31 includes several groups, and several groups of the ventilation seats 31 are arranged in parallel under the storage tank, and the ventilation pipe 32 is connected to several groups of ventilation seats 31 respectively.

[0020] Furthermore, a nitrogen concentration sensor 314 is provided on the lower end surface of the air intake plate 312 .

[0021] Description of the working method of this utility model:

[0022] In the fire-fighting device adopting this structure, the frame 1 can be a frame-like structure formed by welding a combination of square pipes. The storage tank 2 is set on the frame 1. The connection part between the storage tank 2 and the frame 1 is horizontally placed on the square pipe. There can be multiple sets of connecting bases. Therefore, there is a gap between the storage tank 2 and the frame 1. By adding a fire-fighting component 3 that can inhale air at the lower end of the storage tank 2, that is, a ventilation seat 31, the replacement of the air around the storage tank 2 can be achieved. In order to better achieve air inhalation, an air intake plate 312 is provided on the upper end of the ventilation seat 31. The air intake plate 312 has an arc-shaped structure and is connected to the storage tank 2. The bottoms are kept at a distance and parallel to each other. The suction holes 313 provided on the suction plate 312 are connected to the ventilating pipe 32 connected to the air inlet pipe 311 at the lower end of the ventilation seat 31. Therefore, when the vacuum pump 321 connected to the ventilating pipe 32 is evacuated, air will be sucked in from the gap between the suction plate 312 and the storage tank 2, thereby changing the air concentration at the lower end of the storage tank 2. In order to accelerate the flow of air, the distance between the suction plate 312 and the storage tank 2 is kept between 10-20 mm. If it is less than 10 mm, the suction plate 312 will be too small to cause the suction to flow. The air intake space becomes smaller and sufficient air cannot be sucked in. When the distance exceeds 20mm, it is impossible to achieve a good effect of improving the air circulation speed. Therefore, the air intake amount and suction speed are best when the distance is between 10-20mm. In order to save energy for starting the vacuum pump 321 and avoid continuous air replacement when the air concentration around the storage tank 2 is not enough to cause combustion, a nitrogen concentration sensor 314 is set on the lower end surface of the air intake plate 312. By detecting the nitrogen content in the air at the lower end of the air intake plate 312, it can be known whether the proportion of harmful gases exceeds the standard. When the nitrogen content exceeds the standard, it can be detected. air replacement can be performed under these circumstances; since the connection between the storage tank 2 and the rack 1 is fixed by multiple sets of connecting bases, in order to better achieve the air replacement effect around the storage tank 2, multiple sets of ventilation seats 31 can be set, and each set of ventilation seats 31 is arranged in parallel under the storage tank 2, and are all connected to the same set of ventilation pipes 32. Since this type of ventilation does not require a large replacement volume, a set of vacuum pumps 321 can achieve air ventilation, reduce the concentration around the storage tank 2, and make the gas concentration do not reach the conditions for combustion, thereby achieving fire safety and ensuring the protection of the workshop during the glue production process.

[0023] The beneficial effect of the present invention is that the arc-shaped structure of the air suction plate 312 maintains a distance from the bottom of the storage tank 2 and is parallel to each other, so that under the action of the vacuum pump 321, the air at the lower end of the storage tank 2 is replaced. When the distance is between 10-20 mm, the air flow rate and flow rate that can be circulated can be improved. Therefore, under the action of the small vacuum pump 321, air ventilation can be achieved, and the concentration around the storage tank 2 can be reduced so that the gas concentration does not reach the conditions for combustion, thereby achieving fire safety and ensuring the protection of the workshop during the glue production process.
