Description

[Technical field]

[0001] The utility model mainly relates to a gas compressor with a fire extinguishing function. [Background technology]

[0002] In certain specific working environments, such as petrochemicals, coal mines, etc., gas compressors may need to operate in flammable and explosive environments. Gas compressors may generate high temperatures during operation due to various reasons, such as overload, friction, etc. If the temperature is too high, it may cause a fire. If there are no effective fire extinguishing measures, once a fire occurs, the consequences will be disastrous. In view of this, we propose a gas compressor structure with a built-in fire extinguishing function. [Contents of the utility model]

[0004] A gas compressor with a fire extinguishing function, characterized in that it comprises a casing and a fire extinguisher, wherein the casing has an accessory cavity, and the fire extinguisher is placed in the accessory cavity;

[0005] The fire extinguisher comprises a hanging part and a spraying part. The fire extinguisher is hung in the accessory cavity through the hanging part, and the spraying part faces the accessory cavity.

[0006] Preferably, the fire extinguisher is a tank body, and the hanging part and the injection part are respectively located at two ends of the tank body; the tank body is filled with sodium bicarbonate dry powder fire extinguishing agent, and the injection part is provided with a temperature-sensitive glass nozzle to control the injection of the sodium bicarbonate dry powder fire extinguishing agent.

[0007] Preferably, the injection portion is connected to a pressure gauge.

[0008] Preferably, a strip-shaped guide portion is provided along the top of the housing, and the hanging portion is slidably connected to the guide portion to adjust the position of the fire extinguisher.

[0009] Preferably, the guide portion has a guide groove, the guide groove is provided with a bayonet connected thereto, the width of the bayonet is smaller than the width of the guide groove; the hanging portion includes an extension rod and a support joint, the diameter of the extension rod is consistent with the width of the bayonet, the width of the support joint is consistent with the width of the guide groove, and the extension rod passes through the bayonet.

[0010] Compared with the background technology, the utility model has the following beneficial effects:

[0011] The utility model provides a gas compressor with a fire extinguishing function. The structure adds a fire extinguisher to the accessory cavity in the casing, and the position of the fire extinguisher in the accessory cavity can be adjusted; when the parts in the gas compressor are overloaded and a fire occurs, the temperature in the accessory cavity rises, the fire extinguishing agent in the tank body decomposes, and the gas expands. When the expansion force exceeds the compressive strength of the temperature-sensitive glass nozzle, the glass tube of the temperature-sensitive glass nozzle explodes, and gasification produces carbon dioxide and nitrogen. Carbon dioxide directly captures oxygen in the air, and nitrogen can effectively reduce the temperature of the air, thereby achieving the purpose of fire extinguishing, avoiding fire in the gas compressor, and improving production safety. It has the advantages of simple structure, compact coordination, and reasonable design; therefore, it is a product with superior performance in both technical and economic aspects.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] The following is a further description of the specific implementation of the utility model in conjunction with the drawings of the specification, so that the technical solution and its beneficial effects of the utility model are clearer and more explicit. The following description of the embodiments with reference to the drawings is exemplary and intended to explain the utility model, but cannot be understood as limiting the utility model.

[0017] The preferred embodiment provided by the utility model is as follows: Figure 1 and Figure 2 As shown, a gas compressor with a fire extinguishing function includes a casing 1 and a fire extinguisher 2. The casing 1 has an accessory cavity 11, and the fire extinguisher 2 is placed in the accessory cavity 11;

[0018] The fire extinguisher 2 includes a hanging portion 21 and a spraying portion 22 . The fire extinguisher 2 is suspended in the accessory cavity 11 through the hanging portion 21 , and the spraying portion 22 faces the accessory cavity 11 .

[0019] The fire extinguisher 2 is a tank body, and the hanging part 21 and the injection part 22 are respectively located at the two ends of the tank body; the tank body is filled with sodium bicarbonate dry powder fire extinguishing agent, and the tank body is filled with an appropriate amount of driving gas nitrogen. The injection part 22 is provided with a temperature-sensitive glass nozzle 23 to control the injection of the sodium bicarbonate dry powder fire extinguishing agent. The injection part 22 is connected to a pressure gauge 24, so as to check whether the fire extinguisher 2 is normal through the pressure gauge 24; the temperature-sensitive glass nozzle and the pressure gauge are existing products, and the structure is not repeated here.

[0020] A strip guide portion 12 is provided along the top of the housing 1, and a hanging portion 21 is slidably connected to the guide portion 12 to adjust the position of the fire extinguisher 2. The guide portion 12 has a guide groove 13, and the guide groove 13 is provided with a bayonet 14 connected thereto, and the width of the bayonet 14 is smaller than the width of the guide groove 13; the hanging portion 21 includes an extension rod 25 and a support joint 26, and the hanging portion 21 is an integrated structure, and one end of the extension rod 25 away from the support joint 26 is welded to the tank body, and the diameter of the extension rod 25 is consistent with the width of the bayonet 14, and the width of the support joint 26 is consistent with the width of the guide groove 13, and the extension rod 25 passes through the bayonet 14. The fire extinguisher 2 is suspended at the top of the housing 1, and the spraying is faster and covers a larger range.

[0021] In this embodiment, the gas compressor adopts the existing mining air compressor structure. Due to the harsh use environment of mining air compressors, high temperatures may be generated during operation due to various reasons, such as overload, friction, etc. If the temperature is too high, the parts of the air compressor will be damaged and cause a fire. If there are no effective fire extinguishing measures, once a fire occurs, the consequences will be disastrous.

[0022] Therefore, in this structure, a fire extinguisher 2 is added to the accessory cavity 11 in the casing 1; the components of the air compressor are limited by size, and the positions of the components are different. In order to facilitate the movement of the fire extinguisher 2 to the position of the components that are prone to fire, the casing 1 is provided with a guide portion 12, and the fire extinguisher 2 is slidably connected to the guide portion 12 through the hanging portion 21, and can be moved along the guide portion 12 to adjust the position of the fire extinguisher 2. When the components in the gas compressor are overloaded and a fire occurs, the temperature in the accessory cavity 11 rises, the fire extinguishing agent in the tank body decomposes, and the gas expands. When the expansion force exceeds the compressive strength of the temperature-sensitive glass nozzle 23, the glass tube of the temperature-sensitive glass nozzle 23 explodes, and the gasification produces carbon dioxide and nitrogen. Carbon dioxide directly takes away oxygen in the air, and nitrogen can effectively reduce the temperature of the air, thereby achieving the purpose of extinguishing the fire, avoiding fires in the gas compressor, and improving production safety.
