[0057] like Figure 1 , Figure 2 , Figure 4 As shown in the figure, this embodiment provides a portable polyurethane emergency curing device, including a body 1. The body 1 has an installation chamber. At least two installation slots are provided on the front end face of the body 1, namely a first installation slot 2 and a second installation slot 3. The bottoms of the first installation slot 2 and the second installation slot 3 communicate with the installation chamber.

A polyurethane A bottle 4 is also installed in the first installation slot 2, and a polyurethane B bottle 5 is installed in the second installation slot 3. The polyurethane A heating sleeve covers the polyurethane A bottle 4, and the polyurethane B heating sleeve covers the polyurethane B bottle 5. An air compressor 6 and a high-pressure gas cylinder 7 are installed in the installation chamber. The inlet of the high-pressure gas cylinder 7 is connected to the outlet of the air compressor 6 via a pipeline. The machine body 1 has a groove 8 on its side end face. At least three through holes 9, which communicate with the installation chamber, are arranged at intervals along the height at the bottom of the groove 8. A connecting pipe 10 is inserted into each through hole 9. One end of each connecting pipe 10 is located in the groove, and the other end passes through the through hole 9 and extends into the installation chamber.

[0058] It also includes an injection button for sending a start signal to the controller so that the polyurethane A solenoid valve, polyurethane A liquid pump, polyurethane B solenoid valve, polyurethane B liquid pump, gas solenoid valve, and air pump can be opened simultaneously; a stop button for sending a stop signal to the controller so that the polyurethane A solenoid valve, polyurethane A liquid pump, polyurethane B solenoid valve, and polyurethane B liquid pump can be closed simultaneously, and the gas solenoid valve and air pump can be closed after a delay; the controller is configured to receive the signal sent by the injection button and send an opening command to the polyurethane A solenoid valve, polyurethane A liquid pump, polyurethane B solenoid valve, polyurethane B liquid pump, gas solenoid valve, and air pump simultaneously; receive the signal sent by the stop button and send a stop command to the polyurethane A solenoid valve, polyurethane A liquid pump, polyurethane B solenoid valve, and polyurethane B solenoid valve simultaneously, and send a delayed stop command to the gas solenoid valve and air pump; the polyurethane A solenoid valve, polyurethane A liquid pump, polyurethane B solenoid valve, polyurethane B liquid pump, gas solenoid valve, and air pump respectively receive and execute the commands sent by the controller.

[0059] This invention provides a highly portable polyurethane emergency curing device that allows for the simultaneous spraying of two curing agents, enabling rapid curing and forming a sealed enclosure for leaked hazardous materials, isolating contaminants from the air. The polyurethane A bottle (4) and polyurethane B bottle (5) can contain the two curing agents respectively. With the assistance of high-pressure gas, both curing agents can be sprayed out at high speed simultaneously. Furthermore, the device features a spray button, a shut-off button, a polyurethane A electric control valve, a polyurethane A liquid pump, a polyurethane B electric control valve, a polyurethane B liquid pump, a gas electric control valve, an air pump, and a controller, enabling one-button start and one-button shut-off. After shutting down, the device also self-cleans the nozzle, preventing clogging during subsequent use.

[0060] Furthermore, the machine body has a reasonable structural design. The setting of the first mounting slot 2 and the second mounting slot 3 facilitates the placement and replacement of the urethane A bottle 4 and the polyurethane B bottle 5. After the liquid in the urethane A bottle 4 and the polyurethane B bottle 5 is used up, it is easy to replace them, which improves the convenience for users.

[0061] This invention provides a highly portable polyurethane emergency curing device that integrates the above-mentioned components into one unit, making it easy to transport. It can be placed in places where hazardous materials are likely to be present, such as airports, docks, train stations, and ports, allowing for emergency treatment before professionals arrive, preventing the spread of hazardous materials, and ensuring the safety of people in public environments.

[0062] like Figure 4As shown, this embodiment also includes a temperature sensor for bottle A installed on the bottom of polyurethane bottle A 4, used to measure the external temperature of polyurethane bottle A and send the detected temperature value to the controller; a temperature sensor for bottle B installed on the bottom of polyurethane bottle B 5, used to measure the external temperature of polyurethane bottle B and send the detected temperature value to the controller; a pressure sensor installed inside the high-pressure gas cylinder 6, used to measure the internal pressure of the gas cylinder and send the detected pressure value to the controller; an air compressor 6, used to receive and execute commands from the controller; a polyurethane A heating jacket, used to receive and execute commands from the controller; a polyurethane B heating jacket, used to receive and execute commands from the controller; and a controller configured to: acquire a first temperature value from the temperature sensor for bottle A and a second temperature value from the temperature sensor for bottle B, and transmit the first temperature value and the second temperature value to the controller. The temperature values ​​are compared with set thresholds. When both the first and second temperature values ​​are less than the set thresholds, an opening command is sent to the polyurethane A heating jacket and the polyurethane B heating jacket. When the first and second temperature values ​​are greater than the set thresholds, a closing command is sent to the polyurethane A heating jacket and the polyurethane B heating jacket. The signal sent by the injection button is acquired, and the polyurethane A solenoid valve, the polyurethane B solenoid valve, and the gas solenoid valve are simultaneously opened. The signal sent by the close button is acquired, and the polyurethane A solenoid valve and the polyurethane B solenoid valve are simultaneously closed, while the gas solenoid valve is closed with a delay. The pressure value detected by the air pressure sensor is acquired and compared with a set threshold. When the pressure value is less than the set threshold, an opening command is sent to the air compressor 7. When the pressure value is greater than the set threshold, a closing command is sent to the air compressor 7.

[0063] This invention involves installing a temperature sensor for bottle A (4) and a temperature sensor for bottle B (5) on the outside of bottle B. These sensors measure the temperatures outside both bottles A and B and send the measurements to a controller. The controller compares the measured values ​​with preset values ​​to control the heating of bottles A and B respectively. Both bottles are housed within a well-insulated casing. With slow heating, the external temperatures of the heating sleeves (A and B) are essentially equal to their internal temperatures, maintaining the liquid temperature within bottles A and B at approximately 40°C. This ensures effective spraying and prevents nozzle clogging. Simultaneously, the invention monitors the pressure in the high-pressure gas cylinders in real-time and automatically controls the air compressor (7) to fill the high-pressure cylinders with air, ensuring sufficient air supply to power the liquid spray and guaranteeing optimal spraying performance. The system is highly automated and requires no preheating or preparation before use; it is ready to use immediately upon startup.

[0064] like Figure 1As shown, a power supply module is also installed in the installation chamber of this embodiment. The polyurethane A heating jacket 3, polyurethane B heating jacket 3, and air compressor are electrically connected to the power supply module. The power supply module is equipped with a battery temperature sensor and a voltage sensor. The power supply module is used to receive and execute controller commands. The controller is also configured to acquire the battery temperature value from the battery temperature sensor, compare the battery temperature value with a set threshold, and send a stop charging command to the power supply module when the battery temperature value is less than the set lower threshold or greater than the set upper threshold. The controller also acquires the voltage value detected by the voltage sensor, compares the voltage value with a set threshold, and sends a shut-off command to the power supply module when the voltage value is less than the set lower threshold or greater than the set upper threshold. When the pressure value is lower than the set permissible threshold, the controller sends an open command to the charging module.

[0065] This invention, through the electrical connection design of the battery temperature sensor, voltage sensor, controller, and power supply module, can realize the charging and discharging management of the power supply module, while providing safety protection against temperature, over-discharge, and over-charge of the power supply module, and extending the service life of the power supply module. The power supply module is a rechargeable battery pack.

[0066] When the control gas electronic valve of the present invention closes after a delay of 5-10 seconds, it ensures the cleaning effect on the nozzle and avoids the hardener residue inside the nozzle.

[0067] The invention also includes a display connected to the controller for displaying information, featuring a fully Chinese LCD display and fully Chinese operation prompts.

[0068] The device body of this invention is also equipped with an indicator light to display the working status. When the spray button is activated, an indicator light activation signal is sent to the controller, and the controller controls the indicator light to turn on according to the signal. When the shutdown button is activated, an indicator light deactivation signal is sent to the controller, and the controller controls the indicator light to turn off according to the signal.

[0069] In this invention, heating tape is wound around the polyurethane A bottle 4 and polyurethane B bottle 5 that are connected to the corresponding connecting pipe 10 to ensure that the pipe is heated, so that the liquid in the pipe is in a flowing state and the spraying effect is guaranteed.

[0070] The body 1 of this invention is equipped with a shoulder strap, which makes it convenient for the operator to carry the device and allows the operator to operate it with one hand.

[0071] like Figure 1 As shown, this embodiment also includes a box for placing the machine body 1. The box is provided with a machine body 1 placement slot, a pipeline installation slot, a polyurethane A bottle placement slot, a polyurethane B bottle placement slot, a cleaning fluid A bottle placement slot, and a cleaning fluid B placement slot. The outer wall of the box is provided with rollers and a pull rod; it is convenient for storage and transportation and can be dragged.

[0072] like Figure 3As shown, the nozzle of this embodiment includes a housing 91, a mixing chamber 92 inside the housing 91, a first chamber 93 and a second chamber 94 on both sides of the mixing chamber 92, respectively. One side of the housing 91 has a spray outlet 911 communicating with the mixing chamber 92, and the side of the housing 91 away from the spray outlet 911 has an air inlet 912 communicating with the mixing chamber 92, a polyurethane A liquid supply port 913 communicating with the first chamber 93, and a polyurethane B liquid supply port 914 communicating with the second chamber 94. A mixing column 95 is provided inside the mixing chamber 92, and a first liquid outlet communicating with the first chamber 93 and a second liquid outlet communicating with the second chamber 94 are respectively opened on the inner wall of the mixing chamber 92. The first and second liquid outlets are respectively positioned opposite to the mixing column 95; a one-way valve A96 is installed in the first chamber 93 adjacent to the first liquid outlet, a one-way valve B97 is installed in the second chamber 94 adjacent to the second liquid outlet, and a compressed air one-way valve 98 is installed in the mixing chamber 92 adjacent to the air inlet 922; the polyurethane A supply port 913, the polyurethane B supply port 914, and the air inlet 912 are respectively connected to the corresponding connecting pipes on the machine body 1 through pipelines; the two curing agents can be mixed in the mixing chamber 92 inside the nozzle and blown out by high-pressure air. The nozzle has a simple structure, good spraying effect, low cost, and is easy to manufacture, effectively saving on-site work preparation time and improving work efficiency.

[0073] The diameter of the mixing chamber 92 at the mixing column 95 is (6-10):5. This can reduce the diameter of the mixing chamber, making the gas flow channel narrower. This will force the compressed air to flow at high speed through the first liquid outlet and the second liquid outlet, which can carry out, blow away and empty the residual liquid.

[0074] The diameter ratio of the first and second liquid outlets to the mixing column is (4-7):3, which relates to the flow rate during liquid mixing and the effect of the liquid flow around the liquid, further affecting the mixing effect of the two liquids, so that the two liquids are fully mixed to meet the requirements.

[0075] The housing of this invention has machining holes on both sides, and the machining holes are sealed with threaded plugs to facilitate cleaning of the first liquid outlet and the second liquid outlet, thereby preventing liquid from accumulating in the first liquid outlet and the second liquid outlet and affecting the liquid spraying effect.

[0076] The housing 91 is provided with a mixing column perforation, and one end of the mixing column extends into the mixing chamber 92 through the mixing column perforation; the mixing column is easy to disassemble, which facilitates the overall cleaning of the mixing chamber 92.

[0077] Instructions for using the portable polyurethane emergency curing device:

[0078] Start the spraying button, and the controller will control the opening of the polyurethane A solenoid valve, polyurethane A liquid pump, polyurethane B solenoid valve, polyurethane B liquid pump, gas solenoid valve and air pump to achieve simultaneous high-speed spraying of dual curing agents.

[0079] When it needs to be shut down, the shut-off button is activated, and the controller controls the polyurethane A solenoid valve, polyurethane A liquid pump, polyurethane B solenoid valve, and polyurethane B liquid pump to shut down, and controls the gas solenoid valve and gas pump to shut down after a delay.

[0080] In non-working state, temperature sensors A and B monitor the external temperatures of polyurethane bottle A and polyurethane bottle B in real time, respectively. The controller controls the opening of the heating jackets of polyurethane bottle A and polyurethane bottle B to ensure that the external temperatures of polyurethane bottle A and polyurethane bottle B are at 40℃. The pressure sensor monitors the pressure of the high-pressure gas cylinder in real time, and the controller controls the air compressor to supply gas to the gas cylinder so that the gas pressure inside the gas cylinder meets the set threshold.

[0081] The controller is also configured to acquire the battery temperature value from the battery temperature sensor, compare the battery temperature value with a set threshold, and send a stop charging command to the power supply module when the battery temperature value is less than the set lower threshold or greater than the set upper threshold; acquire the voltage value detected by the voltage sensor, compare the voltage value with a set threshold, and send a shut-off command to the power supply module when the voltage value is less than the set lower threshold or greater than the set upper threshold; and send an start command to the charging module when the pressure value is lower than a set permissible threshold; the power supply module receives and executes the controller commands.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
