Description

Technical Field

[0001] This utility model relates to the field of industrial heating equipment safety technology, and in particular to an explosion-proof intelligent alarm device for a thermal oil furnace. Background Technology

[0002] Thermal oil heaters are important thermal energy equipment in industrial production. They use thermal oil as a circulating medium to provide the required thermal energy to heat-consuming industrial equipment.

[0003] Because thermal oil heaters typically operate at high temperatures, the hot oil pumps used are generally centrifugal pumps. If the circulation valve closes during operation and the thermal oil stops flowing, the oil temperature will rise rapidly, which could lead to rupture, leakage, or even explosion due to overpressure. At the same time, thermal oil is also flammable and explosive, and once it leaks, it can easily cause a fire or even an explosion. Therefore, thermal oil heaters are also high-risk equipment in industrial production.

[0004] Therefore, thermal oil heaters must be equipped with comprehensive safety protection devices during operation. Flow meters are one of the important protective devices for thermal oil heaters. They measure the flow rate of thermal oil in the pipeline to prevent accidents such as dry burning, carbonization, and explosions caused by the thermal oil not circulating properly or the flow rate being lower than the preset threshold, thereby ensuring the safe operation of the equipment.

[0005] However, existing flow meters generally only display the flow rate and do not have an alarm function. If the valve is closed and the hot oil does not circulate, the staff will not be able to detect the abnormal flow in time, and an accident will inevitably occur. Therefore, this utility model provides an explosion-proof emergency alarm device for hot oil furnaces. When the flow of heat transfer oil is not smooth or stops, it will automatically issue an alarm to avoid the occurrence of danger. Utility Model Content

[0009] Optionally, an oil inlet pipe is provided near the bottom of the hot oil furnace body, and a second flow meter body is provided on the outer surface of the oil inlet pipe.

[0010] The above technical solution involves installing an oil inlet pipe and a second flow meter body at the bottom of the hot oil furnace body, which, together with the first flow meter body of the oil outlet pipe, forms a bidirectional monitoring system for the inflow and outflow of heat transfer oil.

[0011] Optionally, an L-shaped baffle is provided at the top of the base plate near the explosion-proof box, and the L-shaped baffle is located between the explosion-proof box and the main body of the hot oil furnace.

[0012] The above technical solution can prevent the explosion-proof box from being directly impacted by high temperature or explosive fragments when the hot oil furnace malfunctions, thus protecting the normal operation of the electronic components inside the explosion-proof box and enhancing the overall safety of the device.

[0013] Optionally, the warning light is located on the top of the explosion-proof box, and there are two warning lights, which are symmetrically distributed on the top of the explosion-proof box.

[0014] Through the above technical solution, when the device detects an anomaly, the flashing warning light can alert people in the vicinity from multiple angles.

[0015] Optionally, the front end of the explosion-proof box is hinged to the switch door, and a sealing plate is fixedly connected to the rear end of the switch door. The outer surface of the sealing plate is tightly fitted to the inner wall of the explosion-proof box.

[0016] The above technical solution ensures the airtightness of the explosion-proof box, which allows the box to withstand internal pressure and prevent flame leakage in the event of an accidental explosion.

[0017] Optionally, the front end of the switch door is fixedly connected to the control panel near the left side, and the front end of the switch door is fixedly connected to a handle near the right side.

[0018] The above technical solution involves setting an operation panel near the left side of the front of the door to facilitate staff in setting parameters, viewing data, and other operations.

[0019] Optionally, a buzzer is provided on the right side of the front end of the door, and the number of buzzers is two and they are symmetrically distributed vertically.

[0020] The above technical solution allows multiple buzzers to sound simultaneously, producing a louder and clearer alarm sound. This ensures that even in noisy industrial environments, the alarm sound can still attract the attention of staff, allowing them to take timely countermeasures.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0029] Reference Figure 1-4 This utility model provides an explosion-proof intelligent alarm device for a thermal oil furnace, which includes a base plate 1. A mounting bracket 2 is fixedly connected to the top of the base plate 1 near the rear end. A thermal oil furnace body 3 is installed on the inner wall of the mounting bracket 2. An oil outlet pipe 4 is provided on the top of the thermal oil furnace body 3. A first flow meter body 5 is provided on the outer surface of the oil outlet pipe 4. An explosion-proof box 9 is provided on the base plate 1 near the left front end.

[0030] The hot oil furnace body 3 is provided with an oil inlet pipe 6 near the bottom. The outer surface of the oil inlet pipe 6 is provided with a second flow meter body 7. An L-shaped baffle 8 is provided on the top of the bottom plate 1 near the explosion-proof box 9. The L-shaped baffle 8 is located between the explosion-proof box 9 and the hot oil furnace body 3.

[0031] The explosion-proof box 9 includes a warning light 14, a door switch 10, an operation panel 11, a buzzer 12, a signal receiving module 17, a data transmission module 18, a partition 16, a data processing module 19, and a control device 20.

[0032] Warning lights 14 are located on the top of the explosion-proof box 9. There are two warning lights 14, which are symmetrically distributed on the top of the explosion-proof box 9. The front end of the explosion-proof box 9 is hinged to the switch door 10. The rear end of the switch door 10 is fixedly connected to a sealing plate 15. The outer surface of the sealing plate 15 is tightly fitted to the inner wall of the explosion-proof box 9. The front end of the switch door 10 is fixedly connected to the operation panel 11 near the left side. The front end of the switch door 10 is fixedly connected to the handle 13 near the right side. A buzzer 12 is provided on the right side of the front end of the switch door 10. There are two buzzers 12, which are symmetrically distributed vertically. The middle of the inner wall of the explosion-proof box 9 is fixedly connected to a horizontally placed partition 16. The signal receiving module 17 and the data transmission module 18 are located on the left and right sides of the top of the partition 16, respectively. The data processing module 19 and the control device 20 are located on the left and right sides of the bottom inner wall of the explosion-proof box 9, respectively.

[0033] Working principle: When the explosion-proof intelligent alarm device for thermal oil furnace is working, the first flow meter body 5 on the oil outlet pipe 4 and the second flow meter body 7 on the oil inlet pipe 6 collect the inlet and outlet flow data of thermal oil in real time, and transmit the analog signal to the signal receiving module 17 in the explosion-proof box 9 through the signal cable, and convert it into a digital signal by A / D conversion.

[0034] After the signal receiving module 17 filters and denoises the data, it transmits it to the data processing module 19 through the data transmission module 18. The data processing module 19 has a built-in algorithm to calculate parameters such as the difference between the inlet and outlet oil volume and the flow fluctuation amplitude, and compares them with preset thresholds. When the difference between the inlet and outlet oil volume exceeds the threshold or the flow rate of a single channel drops or rises suddenly, an alarm signal is generated.

[0035] The signal is output in three channels through the control device 20, triggering the warning lights 14 on the left and right sides of the top of the explosion-proof box 9 to flash, and the two buzzers 12 symmetrically positioned at the front of the door 10 to emit an alarm sound. The alarm data is then sent to the central control system via the network through the data transmission module 18.

[0036] The explosion-proof box 9 is made of welded steel plates. The opening and closing door 10 forms an explosion-proof sealing surface through the sealing plate 15. The L-shaped baffle 8 isolates the main body 3 of the hot oil furnace from the explosion-proof box 9 to prevent impact. The operation panel 11 is a touch screen, which can display the flow curve in real time and modify the alarm parameters. The opening and closing door 10 is opened by the handle 13 for easy maintenance. In case of pipe blockage, the warning light 14 flashes quickly and the buzzer 12 sounds continuously. The central control pop-up window displays the pipe blockage, realizing millisecond-level response to abnormal flow of the thermal oil furnace and explosion-proof safety protection.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
