Description

Technical Field

[0001] This utility model relates to fire extinguishing devices, and more particularly to an automatic fire extinguishing device for testing the ignition point of petroleum products. Background Technology

[0002] The ignition point of a petroleum product refers to the lowest temperature at which, when a sample of the petroleum product in a specified open-cup is heated and ignited by a flame of a specified size, the surface of the sample in the sample cup not only flashes upon approaching the flame but also continues to burn for more than 5 seconds. The open-cup ignition point of petroleum products is also known as the flash point or ignition point.

[0003] An open-cup flash point and fire point tester for petroleum products is a specialized instrument for testing the flash point and fire point of petroleum products using the open-cup method. Typically, the flash point and fire point tests for petroleum products are performed on the same instrument. Because the temperature at which the fire point occurs is higher than the temperature at which the flash point occurs, the flash point is tested first, followed by the fire point.

[0004] During petroleum product ignition point testing, once the ignition point is detected, the sample in the test cup has already ignited (i.e., caught fire), and the test is complete. To prevent accidents, the flame in the test cup must be extinguished as quickly as possible. Currently, the common method is to create a round extinguishing cap with a handle, large enough to completely cover the mouth of the test cup. After the ignition point test, while the test cup is still on the instrument's heating furnace, the extinguishing cap is used to cover the mouth of the test cup to extinguish the flame. Alternatively, the test cup can be removed from the heating furnace before the extinguishing cap is used to extinguish the flame. However, this method has limitations and shortcomings.

[0005] 1. Because the flame extinguishing operation is completed manually after the ignition test, it cannot be completed immediately after the ignition test, resulting in a delay in flame extinguishing and posing certain safety hazards.

[0006] 2. Because the flame extinguishing operation after the ignition test is completed by manual control, the instrument for detecting the flash point and ignition point of petroleum products using the open cup method is of low technical level.

[0007] Therefore, developing an automatic fire extinguishing device for testing the ignition point of petroleum products has become an urgent problem for those skilled in the art. Utility Model Content

[0008] This invention addresses the aforementioned shortcomings by providing an automatic fire extinguishing device for petroleum product ignition point testing. Upon completion of the ignition point test, the device automatically receives a signal indicating the test's end and extinguishes the flames immediately without manual intervention. Simultaneously, it includes a manual emergency fire extinguishing button to address any emergency fire extinguishing requirements during the test; simply pressing this button will immediately extinguish the flames automatically.

[0009] The above-mentioned objective of this utility model is achieved through the following technical solution: an automatic fire extinguishing device for testing the ignition point of petroleum products, comprising a control drive circuit board and a rotary motor, wherein the control drive circuit board is connected to a manual fire extinguishing button and an automatic fire extinguishing input signal port, and is connected to the rotary motor through a motor control drive wire, and a fire extinguishing cover is fixed on the rotating shaft of the rotary motor.

[0010] Furthermore, one end of the fire extinguishing cover is connected and fixed to the rotating shaft, and the other end is provided with a sample cup covering part. When the fire extinguishing is started, after the sample cup covering part rotates into place, the sample cup covering part covers the mouth of the sample cup.

[0011] The advantages of this utility model compared with the prior art are:

[0012] 1. It has the advantages of convenient and practical operation for extinguishing internal combustion fires in the sample cup.

[0013] This invention employs an automatic fire extinguishing method, which can automatically extinguish the fire in the sample cup without manual operation, and has the advantages of convenient operation and practicality.

[0014] 2. It has the advantage of rapid fire extinguishing inside the sample cup, eliminating fire hazards and ensuring the safety of the ignition point test.

[0015] This invention employs an automatic fire extinguishing method and has the function of immediately receiving an automatic fire extinguishing signal after the ignition point is closed, and immediately extinguishing the fire inside the sample cup. It has the advantages of rapid fire extinguishing inside the sample cup, eliminating fire hazards, and ensuring the safety of the ignition point test.

[0016] 3. It has the advantage of allowing manual button operation to automatically extinguish fires in special circumstances.

[0017] This utility model has a manual button emergency fire extinguishing function, and this function has the highest priority for automatic fire extinguishing. No matter when or under what circumstances, pressing the manual button can activate automatic fire extinguishing, which has the advantage of being able to automatically extinguish fires in special circumstances at any time.

[0018] 4. It has the advantage of enhancing the technical level of instruments.

[0019] When applied to an open-cup flash point and ignition point testing instrument for petroleum products, this invention can automatically extinguish the fire inside the sample cup without manual intervention after the ignition point test is completed; and at any time and under any circumstances, the fire inside the sample cup can be automatically extinguished in an emergency by simply pressing the manual extinguishing button, which has the advantage of improving the technical level of the instrument.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] like Figure 1 As shown, an automatic fire extinguishing device for testing the ignition point of petroleum products includes a control drive circuit board 3 and a rotary motor 5. The control drive circuit board 3 is connected to a manual fire extinguishing button 1 and an automatic fire extinguishing input signal port 2, and is connected to the rotary motor 5 through a motor control drive wire 4. A fire extinguishing cover 7 is fixed on the rotation shaft 6 of the rotary motor 5. One end of the fire extinguishing cover 7 is connected and fixed to the rotation shaft 6, and the other end is provided with a sample cup covering part. When the fire extinguishing is started, after the sample cup covering part rotates into place, the sample cup covering part covers the mouth of the sample cup 8.

[0028] like Figure 1 As shown, in this utility model:

[0029] Manual fire extinguishing button 1 is a manual emergency fire extinguishing intermittent button. After pressing this button, the generated signal is processed by the control drive circuit board 3 and then drives the rotary motor 5 through the motor drive control wire 4. The fire extinguishing cover 7, which is installed on the rotating shaft 6, rotates 90 degrees counterclockwise to cover the mouth of the sample cup 8, thereby extinguishing the flame in the cup.

[0030] Automatic fire extinguishing input signal port 2 is the automatic fire extinguishing input signal port for the end of the ignition test. When the ignition detection system outside this automatic fire extinguishing device detects the ignition information, it saves the ignition temperature value and displays it on the screen; simultaneously, it sends this information to a dedicated pulse generation circuit, which generates a positive pulse signal. This signal is then transmitted via a transmission wire to this automatic fire extinguishing input signal port as an automatic fire extinguishing signal. After receiving and processing this signal, the control drive circuit board 3 drives the rotary motor 5 through the motor drive control wire 4. The fire extinguishing cover 7, mounted on the rotating shaft 6, rotates 90 degrees counterclockwise, covering the mouth of the sample cup 8, thus extinguishing the flame in the cup.
