Description

Technical Field

[0001] The utility model relates to the technical field of tank containers, in particular to a safety protection device for filling an ISO tank. Background Art

[0002] Products from the production unit include HFC-245fa and HFO-1233zd. After sampling and analysis, they are packaged into ISO tanks. Two filling scales are identical and located close together on site. During filling, the operator connects the filling hose of HFC-245fa or HFO-1233zd to the corresponding ISO tank, then notifies the DCS to open the remote control valve and pump the product into the ISO tank until the valve automatically closes after the set weight is reached. The filling operator then disconnects the filling hose and contacts the gantry crane to lift the ISO tank to the finished product area. The gantry crane operator, located in the cab at a height of about 15 meters, cannot clearly observe that the ISO tank on the filling scale is completely disconnected from the filling hose.

[0003] Because the ISO tank interfaces used for both products are standardized and similar in nature, the filling hoses are made of the same material, size, and connector design. Furthermore, the DCS-controlled valves used for on-site filling share similar digital numbers. Despite the color-coded hoses for the two products, on-site operators could still misconnect the hoses and incorrectly open the remote-controlled valves, potentially leading to incorrect filling or even material leaks. Furthermore, the gantry crane operator cannot clearly see whether the hoses are disconnected from the ISO tanks, potentially causing them to break when moving the ISO tanks, potentially resulting in safety incidents. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem in the prior art that when HFC-245fa and HFO-1233zd are filled into ISO Tanks, malfunction is easily caused on site due to the similar filling structures.

[0005] To solve the above technical problems, the present invention provides a safety protection device for filling an ISO tank, comprising: a first ISO tank; a second ISO tank, which is independent of the first ISO tank; a first hose rack, on which a first filling line is placed, and a first contact switch is provided on the first hose rack, and the first filling line is connected to the first ISO tank via a pipeline; a second hose rack, on which a second filling line is placed, and a second contact switch is provided on the second hose rack, and the second filling line is connected to the second ISO tank via a pipeline; a first valve, which is provided on the pipeline between the first filling line and the first ISO tank, and when the first filling line leaves the first hose rack and the first contact switch is in the "open" state, the first valve can be opened; and a second valve, which is provided on the pipeline between the second filling line and the second ISO tank, and when the second filling line leaves the second hose rack and the second contact switch is in the "open" state, the second valve can be opened. The ISO tank filling safety protection device of the utility model interlocks the filling valves of corresponding products through the contact switch on the hose rack, thereby preventing the possibility of the remote valve being opened by mistake and eliminating the hidden dangers of quality and leakage.

[0006] In one embodiment of the present invention, the first contact switch is connected to a first transmitter, and a switch signal of the first contact switch is transmitted to the first valve through the first transmitter.

[0007] In one embodiment of the present invention, the second contact switch is connected to a second transmitter, and a switch signal of the second contact switch is transmitted to the second valve through the second transmitter.

[0008] In one embodiment of the present invention, the area where the first hose rack and the second hose rack are installed is a filling area.

[0009] In one embodiment of the present invention, a first warning light and a second warning light are provided on the ceiling of the filling area. The first warning light is connected to a first contact switch, and the second warning light is connected to a second contact switch. Adding the first and second warning lights on-site to indicate the connection status of the hose can clearly prompt the gantry crane operator to operate.

[0010] In one embodiment of the present invention, when the first contact switch is in the "on" state, the first warning light flashes to give an alarm to prevent the first ISO Tank from being moved.

[0011] In one embodiment of the present invention, when the second contact switch is in the "on" state, the second warning light flashes to give an alarm to prevent the second ISO Tank from being moved.

[0013] In one embodiment of the present invention, a second pipeline is provided between the second ISO Tank and the second filling line, the second valve is provided on the second pipeline, and the second valve is used to open or close the second pipeline.

[0014] In one embodiment of the present invention, a first quick connector is provided between the first pipeline and the first ISO Tank, and a second quick connector is provided between the second pipeline and the second ISO Tank.

[0015] The above technical solution of the utility model has the following beneficial effects compared with the prior art:

[0016] The ISO tank filling safety protection device of the present invention controls the remote control valve for filling to prevent it from being opened by mistake by adding a status signal of the hose in the control system, thereby achieving error-proof control.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0022] Reference Figure 1 、 2 As shown, the safety protection device for filling an ISO tank of the present invention includes: a first ISO tank 100; a second ISO tank 200, which is independent of the first ISO tank 100; a first hose rack, on which a first filling line 1 is placed, and a first contact switch 2 is provided on the first hose rack, and the first filling line 1 is connected to the first ISO tank 100 via a pipeline; a second hose rack, on which a second filling line 3 is placed, and a second contact switch 4 is provided on the second hose rack, and the second filling line 3 is connected to the second ISO tank 200 via a pipeline; a first valve 5, which is provided on the pipeline between the first filling line 1 and the first ISO tank 100, and when the first filling line 1 leaves the first hose rack and the first contact switch 2 is in the "open" state, the first valve 5 can be opened; and a second valve 6, which is provided on the pipeline between the second filling line 3 and the second ISO tank 200, and when the second filling line 3 leaves the second hose rack and the second contact switch 4 is in the "open" state, the second valve 6 can be opened.

[0023] In the above structure, the first contact switch 2 is connected to the first transmitter 7, and its switching signal is transmitted to the first valve 5 via the first transmitter 7. The second contact switch 4 is connected to the second transmitter 8, and its switching signal is transmitted to the second valve 6 via the second transmitter 8. The operating principle of the first contact switch 2, the second contact switch 4, the first valve 5, the second valve 6, the first transmitter 7, and the second transmitter 8 is that the contact switch generates two signals, open and close. When the hose is removed from the hose rack, the contact switch generates a closed "open" signal, which is transmitted to the valve via the transmitter. Only after the valve receives the "open" signal can it be opened on the control panel. Conversely, when the hose is in the hose rack, the switch generates a closed "close" signal, which is transmitted to the valve via the transmitter. After the valve receives the "close" signal, it is not allowed to open.

[0024] In the above structure, the area where the first and second hose racks are installed constitutes the filling area. The ceiling of the filling area is equipped with first and second alarm lights 9 and 10. The first alarm light 9 is connected to the first contact switch 2, and the second alarm light 10 is connected to the second contact switch 4. Specifically, the first and second hose racks are added next to the product filling scale, and the first and second filling lines 1 and 3 of the corresponding products are placed. The first and second contact switches 2 and 4 on the first and second hose racks are interlocked with the corresponding first and second filling remote control valves 5 and 6.

[0025] In the above configuration, when the first contact switch 2 is in the "on" position, the first warning light 9 flashes to signal an alarm, preventing the movement of the first ISO tank 100. When the second contact switch 4 is in the "on" position, the second warning light 10 flashes to signal an alarm, preventing the movement of the second ISO tank 200. By adding on-site hose status alarms, namely the first warning light 9 and the second warning light 10, operating safety for the gantry crane operator is greatly improved, reducing the possibility of hose breakage.

[0026] In the above structure, a first pipe 11 is provided between the first ISO Tank 100 and the first filling line 1. The first valve 5 is disposed on the first pipe 11 and is used to open or close the first pipe 11. A second pipe 12 is provided between the second ISO Tank 200 and the second filling line 3. The second valve 6 is disposed on the second pipe 12 and is used to open or close the second pipe 12. A first quick connector 13 is provided between the first pipe 11 and the first ISO Tank 100, and a second quick connector 14 is provided between the second pipe 12 and the second ISO Tank 200.

[0027] The working principle of the ISO Tank filling safety protection device of the utility model is as follows:

[0028] By adding a first contact switch 2 and a second contact switch 4 to the first hose rack and the second hose rack of the filling hoses of the two products respectively;

[0029] The first contact switch 2 and the second contact switch 4 are interlocked with the corresponding remote-controlled first valve 5 and second valve 6 respectively. When the contact switch is in the "off" state, the corresponding product remote-controlled valve is in the interlocked closed state and cannot be opened; only when this contact switch is in the "on" state can the corresponding remote-controlled valve be opened; in this way, the remote-controlled valve for filling is prevented from being opened incorrectly, avoiding an erroneous filling process.

[0030] At the same time, two red alarm lights, the first alarm light 9 and the second alarm light 10, are added to the top of the canopy in the filling area, which are respectively connected to the switch signals on the first hose rack and the second hose rack. When the first filling pipeline 1 or the second filling pipeline 3 is removed from the first hose rack and the second hose rack, and the contact switch is in the "on" state, the first alarm light 9 and the second alarm light 10 of the alarm start flashing to remind the gantry crane driver not to move the ISO Tank to prevent the hose from being pulled off in the connected state.

[0031] When the hose is disconnected from the ISO Tank and placed back on the first hose rack or the second hose rack, and the first contact switch 2 or the second contact switch 4 is in the "off" state, the first alarm light 9 and the second alarm light 10 of the alarm stop sounding, reminding the gantry crane operator that the hose is disconnected from the ISO Tank. After confirmation with the filling operator, the ISO Tank can be moved.

[0032] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
