Technical Field
[0001] This utility model relates to the field of LPG gas technology, specifically to a novel LPG gas supply chamber. Background Technology
[0002] Liquefied petroleum gas (LPG) is a multi-component hydrocarbon compound primarily composed of propane. LPG is a gas at room temperature and pressure, but when pressurized to approximately 0.8 MPa (pressure varies depending on the composition; propane is used as an example), it can liquefy at room temperature (20°C). Besides being used as a chemical feedstock, LPG is widely used as fuel for urban and rural residents, and its supply and sales network covers urban and rural areas throughout China.
[0003] LPG supply systems are mostly used in construction site canteens, company and institution canteens, commercial restaurants, hotels, agritourism resorts, and other catering service venues. Therefore, there is an urgent need for a highly integrated, intelligent, and safe LPG supply unit that can meet customer needs to the greatest extent possible. Utility Model Content

Detailed Implementation
[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0034] This embodiment 1 provides a novel LPG supply chamber, such as Figure 1 As shown, it includes:
[0035] The storage unit 1 has doors and windows installed on its side walls;
[0036] LPG cylinder 11 is placed in the chamber 1;
[0037] A gas supply pipeline, one end of which is connected to the outlet of the LPG cylinder 11, and the other end of which is connected to the actuator. The gas supply pipeline is equipped with a pressure detection device 4, an emergency shut-off solenoid valve 9, a safety relief device 12, and a regulating valve 7.
[0038] Automatic fire extinguishing device 2 is fixed on the top wall inside the chamber 1;
[0039] Temperature detection device 5 is fixedly installed on the side wall of the chamber;
[0040] An explosion-proof fan 10 is installed on the side wall of the chamber 1;
[0041] A combustible gas detection device 8 is installed on the inner side wall of the chamber 1 near the bottom of the chamber 1;
[0042] The controller 3 is electrically connected to the pressure detection device 4, the emergency shut-off solenoid valve 9, the temperature detection device, the combustible gas detection device 8, and the explosion-proof fan 10.
[0043] The controller can connect to the terminal via a wireless signal transmission module. The terminal can refer to the staff's mobile phone, computer, etc. Meanwhile, the power supply for the controller can be AC power or a battery. The signal transmission, power supply and controller model of the controller are all existing technologies, and will not be described in detail here.
[0044] In this technical solution, placing the LPG cylinders inside the storage compartment reduces the likelihood of them coming into direct contact with open flames, and also reduces the risk of injury or death from LPG cylinder explosions or fires. Furthermore, the integrated skid-mounted design of the LPG supply compartment in this embodiment simplifies on-site installation and facilitates overall relocation.
[0045] Of course, for overall relocation, casters with braking function can be installed on the bottom of the outer side of the compartment.
[0046] By installing an automatic fire extinguishing device, when an LPG cylinder catches fire and causes the temperature inside the chamber to rise, the automatic fire extinguishing device can automatically release extinguishing agent to achieve the effect of extinguishing the fire.
[0047] Once the temperature detection device detects that the temperature inside the chamber is higher than the upper temperature limit, the controller starts the explosion-proof fan to increase the air circulation speed inside the chamber, thereby achieving the purpose of cooling.
[0048] Since LPG has a higher density than air, placing the combustible gas detection device near the bottom of the storage tank can quickly detect whether there is LPG near the bottom of the tank. If so, it can be determined that there is a gas leak in the LPG cylinder or gas supply line. At this time, the controller can transmit the gas leak detection signal to the terminal to notify the staff.
[0049] Doors and windows can be hinged doors and blinds.
[0050] It should also be noted that the installation of a door on the chamber allows staff to easily enter and exit the chamber to replace LPG cylinders and inspect the various working components inside the chamber. Louvers are also installed to facilitate air circulation inside and outside the chamber when the explosion-proof fan is turned on.
[0051] It should also be noted that the relative position of the automatic fire extinguishing device and the LPG cylinder can be set according to the actual situation. The automatic fire extinguishing device can be set directly above or diagonally above the LPG cylinder, as long as the extinguishing agent sprayed by the automatic fire extinguishing device can extinguish the flame of the burning LPG cylinder.
[0052] The emergency shut-off solenoid valve is used to cut off the output of the medium. When pressure, temperature, leakage, fire, or other factors require the output to be cut off, the emergency shut-off solenoid valve is closed to achieve this.
[0053] The executing device is the device that uses LPG, such as a gas stove.
[0054] In some embodiments, because the amount of LPG used per unit time is large, a vaporization device 6 may also be installed on the gas supply pipeline.
[0055] The gasification device can be ambient temperature type, electric heating type, etc.
[0056] In some embodiments, the pressure detection device 4 includes a local pressure gauge and a pressure transmitter, the pressure transmitter being electrically connected to the controller 3.
[0057] The purpose of setting up a pressure transmitter is to enable the controller to collect the air pressure of the air supply pipeline, thereby enabling the controller to monitor the air pressure of the air supply pipeline.
[0058] The purpose of installing both pressure transmitters and local pressure gauges is to verify each other using two different types of pressure gauges. Additionally, the local pressure gauges allow staff to directly observe the pressure values in the pipeline.
[0059] In some embodiments, the automatic fire extinguishing device 2 is a suspended temperature-sensitive glass bulb dry powder fire extinguisher.
[0060] In some embodiments, the automatic fire extinguishing device 2 is a suspended thermal aerosol fire extinguisher.
[0061] In this LPG supply chamber, a temperature-sensing glass bulb or thermal wire is used as the temperature sensing element, and dry powder or aerosol is used as the extinguishing agent. When the temperature sensing element detects that the ambient temperature has reached the set value, the fire extinguishing device releases the extinguishing agent to achieve automatic fire suppression.
[0062] The automatic fire extinguishing device in this embodiment is a non-electrically driven automatic fire extinguisher. The suspended heat-sensitive glass bulb dry powder fire extinguisher is a suspended dry powder fire extinguisher, and the suspended heat-sensitive wire aerosol fire extinguisher is an aerosol automatic fire extinguisher. Both types of automatic fire extinguishers are existing finished products, and the installation of these two types of automatic fire extinguishers is also existing. Therefore, they will not be described in detail here.
[0063] In some embodiments, an alarm device 13 is also included, which is installed on the outer side wall of the compartment 1 and is electrically connected to the controller 3.
[0064] When the temperature, LPG gas concentration, or gas supply pipeline pressure in the chamber exceed the corresponding set thresholds, the alarm device will sound, alerting staff to take action.
[0065] In some embodiments, the alarm device 13 is an alarm flashing light, a buzzer, or an audible and visual alarm.
[0066] In some embodiments, the controller 3 is connected to a remote terminal (not shown in the figure) via a communication module (not shown in the figure).
[0067] Remote terminals can be control terminals such as computers and mobile phones.
[0068] The controller automatically interlocks with the emergency shut-off solenoid valve, explosion-proof fan, and alarm device when any of the monitored data, such as gas concentration, pipeline pressure, or ambient temperature, exceeds the set value.
[0069] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
