Description

Technical Field

[0001] This utility model relates to the field of metal insulation board processing technology, and in particular to a device for spraying polyurethane insulation layer on metal insulation boards. Background Technology

[0002] Metal insulation panels are a common building material used in construction, refrigeration, and industrial facilities, offering excellent thermal insulation performance. Their main structure consists of a combination of metal and insulation materials. The metal panels are typically made of steel or aluminum, while the insulation layer may be made of polyurethane, rock wool, or glass wool. Currently, during the manufacturing process, metal insulation panels are coated with an insulating paint to enhance their thermal insulation effect.

[0003] During use, the isocyanate component in the coating of existing polyurethane insulation layer spraying equipment for metal insulation boards may react with water or moisture to release toxic or irritating gases, such as carbon dioxide, nitrogen oxides and isocyanate vapors. However, most of these equipment are not equipped with harmful gas filtration and adsorption functions, resulting in the direct release of harmful gases into the air, which can easily cause environmental pollution and may even affect the health of workers.

[0004] Therefore, it is necessary to provide a polyurethane insulation layer spraying device for metal insulation boards to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a polyurethane insulation layer spraying device for metal insulation boards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a polyurethane insulation layer spraying device for metal insulation boards, comprising a spraying box, a processing box fixedly connected to the back of the spraying box via a mounting plate, an air quality detector and an air flow rate detector sequentially installed on the surface of the processing box from top to bottom, two alarm lights installed on the surface of the processing box, two placement frames fixedly connected to both sides of the inner wall of the processing box, an activated carbon adsorption plate slidably connected between two opposite placement frames, and a filter plate slidably connected between the other two opposite placement frames, an air outlet pipe fixedly connected to the top of the processing box, a PLC controller installed on the top of the spraying box, an air suction component provided on the surface of the processing box, a spraying component provided on the top of the spraying box, an air collection frame installed on the spraying component via several support frames, a liquid extraction component provided on the surface of the spraying box, and a motor installed on the top of the spraying box.

[0007] The air intake and spraying components draw the air generated during the spraying process into the spraying box. The air then moves upward and passes through the filter plate and activated carbon adsorption plate in sequence. The filter plate filters out solid particles in the air, and the activated carbon adsorption plate adsorbs harmful gases in the air.

[0008] As a further description of the above technical solution:

[0009] The air intake assembly includes an air pump mounted on the surface of the processing chamber. The input end of the air pump is fixedly connected to a three-way flexible hose, and a solenoid valve is installed inside the three-way flexible hose.

[0010] By setting up an air pump, air during the spraying process can be drawn into the three-way hose, and then discharged into the treatment box for processing using the output end of the air pump.

[0011] As a further description of the above technical solution:

[0012] The output end of the air pump is fixedly inserted into the interior of the processing box and located below the filter plate. The two ends of the three-way hose are respectively inserted into the interior of the two air collection frames and are fixedly connected to the air collection frames.

[0013] As a further description of the above technical solution:

[0014] The spraying assembly includes two mounting frames fixedly extending through the top of the spraying box. A reciprocating screw is rotatably connected to one side of the inner wall of each of the two mounting frames. A connecting shaft is fixedly connected to one end of the reciprocating screw, and one end of the connecting shaft extends through to the outside of the mounting frame and is fitted with a pulley.

[0015] As a further description of the above technical solution:

[0016] The reciprocating lead screw has a moving block threadedly connected to its outer surface. A hollow plate is fixedly connected to the bottom of the moving block, and several nozzles are fixedly connected to the surface of the hollow plate.

[0017] By having the motor drive one of the connecting shafts and using two pulleys, the other connecting shaft can be driven to rotate. This causes the two connecting shafts to drive two reciprocating lead screws to rotate, which in turn causes the moving block to move the hollow board and several spray nozzles, thus enabling the metal insulation board to be sprayed from all directions.

[0018] As a further description of the above technical solution:

[0019] The liquid extraction assembly includes a storage tank fixedly connected to the surface of the spray box, and a liquid extraction pump is installed on the top of the storage tank.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1-5 This utility model provides a polyurethane insulation layer spraying device for metal insulation boards: It includes a spraying box 1, a processing box 2 fixedly connected to the back of the spraying box 1 via a mounting plate, an air quality detector 3 and an air flow rate detector 4 sequentially mounted on the surface of the processing box 2 from top to bottom, two alarm lights 5 mounted on the surface of the processing box 2, two placement frames 6 fixedly connected to both sides of the inner wall of the processing box 2, an activated carbon adsorption plate 7 slidably connected between two opposing placement frames 6, and a filter plate 8 slidably connected between the other two opposing placement frames 6, an air outlet pipe 9 fixedly connected to the top of the processing box 2, a PLC controller 10 mounted on the top of the spraying box 1, an air suction component on the surface of the processing box 2, a spraying component on the top of the spraying box 1, a gas collection frame 11 mounted on the spraying component via several support frames, and a liquid extraction component on the surface of the spraying box 1. A motor 12 is installed on the top of the spray box 1. Clamping frames 27 are fixedly connected to the top and bottom of the inner wall of the spray box 1. The filter plate 8 is located below the activated carbon adsorption plate 7. The air quality detector 3 is located between the air outlet pipe 9 and the activated carbon adsorption plate 7 and is used to detect the air quality above the activated carbon adsorption plate 7. The air flow rate detector 4 is located between the activated carbon adsorption plate 7 and the filter plate 8 and is used to detect the flow rate of the gas on the filter plate 8. The PLC controller 10 is electrically connected to the air quality detector 3, the air flow rate detector 4 and the two alarm lights 5. Through the air intake assembly and the spraying assembly, the air generated during the spraying process can be drawn into the interior of the spray box 1. Then the air moves upward and passes through the filter plate 8 and the activated carbon adsorption plate 7 in sequence. At this time, the filter plate 8 filters down the solid particles in the air, and then the activated carbon adsorption plate 7 adsorbs the harmful gases in the air.

[0036] The air intake assembly includes an air pump 13 mounted on the surface of the treatment chamber 2. The input end of the air pump 13 is fixedly connected to a three-way hose 14. A solenoid valve 15 is installed inside the three-way hose 14. The output end of the air pump 13 is fixedly inserted into the interior of the treatment chamber 2 and located below the filter plate 8. The two ends of the three-way hose 14 are respectively inserted into the interior of two air collection frames 11 and are fixedly connected to the air collection frames 11. The solenoid valve 15 is electrically connected to the PLC controller 10, the air quality detector 3, and the air flow rate detector 4. The solenoid valve 15 is installed on the main pipe of the three-way hose 14. By setting the air pump 13, the air in the spraying process can be drawn into the three-way hose 14, and then discharged into the treatment chamber 2 for treatment using the output end of the air pump 13.

[0037] The spraying assembly includes two mounting frames 16 fixedly extending through the top of the spraying box 1. A reciprocating screw 17 is rotatably connected to one side of the inner wall of each mounting frame 16. One end of the reciprocating screw 17 is fixedly connected to a connecting shaft 18. One end of the connecting shaft 18 extends through to the outside of the mounting frame 16 and is fitted with a pulley 19. The two pulleys 19 are connected via belt drive. The output end of the motor 12 is fixedly connected to one end of one of the connecting shafts 18. A moving block 20 is threaded onto the outer surface of the reciprocating screw 17. The bottom of the moving block 20... A hollow plate 21 is fixedly connected to the part, and several spray nozzles 22 are fixedly connected to the surface of the hollow plate 21. One side of the moving block 20 is slidably connected to one side of the inner wall of the mounting frame 16. By having the motor 12 drive one of the connecting shafts 18 and using two pulleys 19, the other connecting shaft 18 can be driven to rotate, so that the two connecting shafts 18 drive two reciprocating screws 17 to rotate respectively, thereby causing the moving block 20 to move the hollow plate 21 and several spray nozzles 22, so as to carry out the spraying work on the metal insulation board from all directions.

[0038] The liquid extraction assembly includes a storage tank 23 fixedly connected to the surface of the spray box 1. A liquid extraction pump 24 is installed on the top of the storage tank 23. The output end of the liquid extraction pump 24 is fixedly connected to a three-way flexible hose 25. The input end of the liquid extraction pump 24 is fixedly connected to an inlet pipe 26. The other two ends of the three-way flexible hose 25 pass through the interior of two hollow plates 21 and are fixedly connected to the interior of the hollow plates 21. One end of the inlet pipe 26 is fixedly connected to the interior of the storage tank 23.

[0039] Working principle: In use, first open the door of the spray box 1 and place the metal insulation board to be sprayed between the two clamping frames 27 to clamp the metal insulation board. Then close the door and start the liquid pump 24 to draw the spraying liquid in the storage tank 23 into the liquid inlet pipe 26 and the three-way hose 25. Then the three-way hose 25 will deliver the spraying liquid to the two hollow plates 21 and spray it out by the nozzles 22. At the same time, start the motor 12, so that the motor 12 drives one of the connecting shafts 18 and the corresponding pulley 19 to rotate. At this time, the pulley 19 will drive the other pulley 19 to rotate by the belt, so that the other pulley 19 drives the other connecting shaft 18. Then the two connecting shafts 18 will drive the two reciprocating screws 17 to rotate, so that the moving block 20 on the reciprocating screw 17 drives the hollow plate 21, and then drives several nozzles 22 to move, so that the two sides of the metal insulation board can be sprayed.

[0040] During the spraying process, the air pump 13 is started and the solenoid valve 15 is opened. At this time, suction is generated inside the three-way hose 14. The air containing harmful gases is then drawn into the three-way hose 14 by the air collection frame 11 and delivered to the processing box 2. The air flows upwards, passing sequentially through the filter plate 8 and the activated carbon adsorption plate 7. The filter plate 8 filters fixed particles in the air, and the activated carbon adsorption plate 7 adsorbs harmful gases. As the usage time increases, the airflow detector 4 detects the airflow velocity above the filter plate 8. If the airflow velocity above the filter plate 8 is lower than a preset value, the filter plate 8 is considered blocked. The airflow detector 4 will generate a signal, which is received by the PLC controller 10. After receiving the signal, the PLC controller 10 will activate the alarm light 5 corresponding to the air flow rate detector 4 and close the solenoid valve 15. Subsequently, after hearing the alarm, the staff will open the door of the processing box 2 and remove the filter plate 8 for cleaning. After cleaning, the filter plate 8 will be installed inside the two opposing placement frames 6. Similarly, the air quality detector 3 will detect the air quality above the activated carbon adsorption plate 7. If the detection is unqualified, it means that the adsorption capacity of the activated carbon adsorption plate 7 has deteriorated. At this time, the air quality detector 3 will send a signal, which will be received by the PLC controller 10, activating the alarm light 5 corresponding to the air quality detector 3 and closing the solenoid valve 15, so that the staff can open the processing box 2 in time and remove the activated carbon adsorption plate 7 for replacement.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
