Description

Technical Field

[0001] This utility model relates to the technical field of flash point testers with automatic dry powder fire extinguishing devices, and particularly to a flash point tester with an automatic dry powder fire extinguishing device. Background Technology

[0002] In modern chemical production processes, flash point is a safety indicator for the storage, transportation, and use of flammable liquids, as well as an indicator of the volatility of flammable liquids. Existing flash point measurement instruments are quite mature, but the situation of oil ignition is often overlooked when measuring flash point, which cannot be effectively addressed, leading to damage to analytical instruments and causing safety accidents.

[0003] Secondly, in actual operation, flammable liquids with low flash points are prone to ignition due to their high volatility. When the ignition rod is used for sweeping tests, the oil cup may suddenly ignite, resulting in poor safety. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a flash point tester with an automatic dry powder fire extinguishing device. This utility model is achieved through the following technical solution:

[0005] A flash point tester with an automatic dry powder fire extinguishing device includes a flash point tester, a testing platform, a rear side plate on the rear side of the testing platform, a left side plate on the left side, and a right side plate on the right side. A lever is provided on the right side plate. A test cup is placed on the testing platform. A fire extinguishing device is provided above the test cup on the left side plate. The fire extinguishing device includes a fire source sensor and a housing. A circuit board is housed inside the housing. The circuit board is circular. Several probes are arranged in a circular array on the circuit board facing the test cup. The signal output terminal of the fire source sensor is electrically connected to the signal input terminal of a programmable logic controller (PLC). The signal output terminal of the PLC is electrically connected to the activation valve of a dry powder fire extinguisher. The dry powder fire extinguisher has a bottle valve and a spray bar with a nozzle facing the test cup.

[0006] As a preferred embodiment, the flash point tester is equipped with a voltmeter, a switch, and a display.

[0007] As a preferred embodiment, the dry powder fire extinguisher and the fire source sensor are located on the same side.

[0008] As a preferred embodiment, the programmable logic controller is fixedly connected to the left side panel.

[0009] Compared with the prior art, the beneficial effects of this utility model are: if the experimental cup catches fire or boils over during flash point analysis, a fire extinguishing device can be used to quickly and effectively extinguish the fire, and the degree of automation is high, minimizing the harm caused by the fire. Attached Figure Description

[0010] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0011] Figure 1 This is a schematic diagram of the connection structure of this utility model;

[0012] Figure 2 This is a schematic diagram of the connection structure between the circuit board and the probe of this utility model. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0014] A flash point tester with an automatic dry powder fire extinguishing device includes a flash point tester 1. The flash point tester 1 includes a testing platform 2. The testing platform 2 has a rear side plate 21 on its rear side, a left side plate 22 on its left side, and a right side plate 23 on its right side. A lever 3 is provided on the right side plate 23. A test cup 4 is provided on the testing platform 2. A fire extinguishing device 5 is provided on the left side plate 22 above the position of the test cup 4. The fire extinguishing device 5 includes a fire source sensor 6. The fire source sensor 6 includes a housing 61. A circuit board 62 is disposed inside the housing 61. The circuit board 62 is circular, and several probes 7 are connected in parallel in a circular array on the side facing the experimental cup 4. The signal output terminal of the fire source sensor 6 is electrically connected to the signal input terminal of the programmable logic controller 8. The signal output terminal of the programmable logic controller 8 is electrically connected to the start valve 10 of a dry powder fire extinguisher 9. The dry powder fire extinguisher 9 is equipped with a bottle valve 11, which is normally open during the use of the flash point tester. The dry powder fire extinguisher 9 is equipped with a spray bar 12, and the spray bar 12 is equipped with a nozzle 13, which faces the experimental cup 4.

[0015] Furthermore, the flash point tester 1 is equipped with a voltmeter 14, a switch 15, and a display 16.

[0016] Furthermore, the dry powder fire extinguisher 9 and the fire source sensor 6 are located on the same side.

[0017] Furthermore, the programmable logic controller 8 is fixedly connected to the left side plate 22.

[0018] When the flash point tester with automatic dry powder fire extinguishing device is in use, if a fire occurs while the oil to be tested for flash point is placed in the test cup, the fire source sensor 6 can collect the fire signal in time. Several probes 7 connected in parallel can collect the fire source signal over a wider area more quickly. The fire source sensor 6 uploads the collected fire signal to the programmable logic controller 8. The programmable logic controller 8 controls the start valve 10 of the dry powder fire extinguisher 9 to work. When the start valve 10 is opened, the dry powder fire extinguisher 9 sprays a large amount of dry powder from the nozzle 13 toward the test cup 4 to extinguish the fire in time and minimize the damage of the fire as much as possible.

[0019] The specific implementation of this utility model has been described in detail above, but it is only an example. This utility model is not limited to the specific implementation cases described above, and equivalent modifications to this utility model are also within the protection scope of this utility model.
