Abstract
Description
Technical Field
[0001] This application belongs to the field of powder extraction and detection technology, specifically a powder extraction explosion-proof protection device for the entire process of noodle making. Background Technology
[0002] In the production of instant noodles, powder sampling and testing is a crucial quality control step. This testing helps determine the quality of the instant noodle powder, including indicators such as protein content, moisture content, and ash content. Manufacturers can monitor changes in raw material quality in real time and adjust production processes and formulas accordingly to ensure the consistency and stability of the final product.
[0003] Flour is primarily composed of carbohydrates. When flour dust reaches a certain concentration, the dust particles, when mixed with air, reach their explosive limit. Upon contact with an open flame, these components can rapidly burn, releasing a large amount of heat and gas, leading to an explosion. The reasons why instant noodle powder extraction is prone to explosion are multifaceted. The extraction process typically uses a negative pressure pump with an extraction tube at the front. This design makes the already heated flour more reactive in the air, increasing the risk of explosion. Furthermore, static electricity generated from friction between flour particles in the air can also be a contributing factor to the explosion.
[0004] However, in traditional powder extraction operations, there is no corresponding explosion-proof protection structure, which reduces safety. Utility Model Content
[0005] The purpose of this application is to address the problem of reduced safety in traditional powder extraction operations due to the lack of corresponding explosion-proof protection structures, and to provide an explosion-proof protection device for powder extraction during the entire flour production process.
[0006] The technical solution adopted in this application is as follows: A powder extraction explosion-proof protection device for the entire process of noodle making includes a protective shell, a circuit body shell welded to the outer surface of the protective shell, a semiconductor cooling chip fixedly connected to the inner surface of the circuit body shell, a temperature guide plate fixedly connected to the inner surface of the circuit body shell, a cooling guide rod provided on the inner surface of the circuit body shell corresponding to the temperature guide plate, a clamping rod welded to the outer surface of the circuit body shell, a threaded ring welded to the inner surface of the circuit body shell, and a tapered tube movably connected to the inner surface of the threaded ring.
[0007] By adopting the above technical solution, the front end of the powder extraction device, through a threaded ring and corresponding to the threaded groove, screws into the conical tube by unscrewing the conical tube. The inner diameter of the conical tube decreases from large to small, and the outer clamping rod contracts inward to clamp the front end of the powder extraction device. The working principle of the semiconductor cooling chip is based on the Peltier effect. Current absorbs heat at one end, forming a cold end, and releases heat at the other end, forming a hot end. The semiconductor cooling chip absorbs heat at the side corresponding to the temperature conductor and releases heat at the side corresponding to the threaded ring. The temperature conductor conducts the low temperature to the outside through the cooling guide rod, so that the front end of the powder extraction device is in a cold air state, which reduces the expansion activity of the flour during powder extraction and facilitates explosion prevention.
[0008] As a further description of the above technical solution, an antistatic sheet is welded to the outer surface of the tapered tube, a grounding wire is welded to the outer surface of the antistatic sheet, and the other end of the grounding wire is welded to the protective shell.
[0009] By adopting the above technical solutions, the antistatic sheet and grounding wire can also be easily grounded, avoiding the cause of flour explosion triggered by static electricity generated by air electrons.
[0010] As a further description of the above technical solution, a switch is provided on the outer surface of the protective housing, and a power connector is fixedly connected to the outer surface of the protective housing.
[0011] By adopting the above technical solution, the switch makes it easy to turn on the equipment for power-on operation, and the power connector makes it easy to connect to the power source.
[0012] As a further description of the above technical solution, a side gasket is fixedly connected to the inner surface of the protective shell, and a fixing plate is fixedly connected to the inner surface of the end of the protective shell away from the main circuit body shell.
[0013] By adopting the above technical solution, the side gasket and the fixing plate can be used to fix the rear end of the powder extraction device. The side gasket clamps the surface of the powder extraction device on both sides, and the powder extraction device is fixed by being snapped into the middle surface of the fixing plate. The fixing plate wraps around and fixes the powder extraction device.
[0014] As a further description of the above technical solution, a side slide plate is movably connected to the inner surface of the protective shell, and an anti-slip groove is fixedly connected to the outer surface of the side slide plate.
[0015] By adopting the above technical solution, the side slide plate can be easily opened to place the powder extraction device, and the anti-slip groove avoids the reduction of friction caused by sweat on the hands, making it difficult to open the side slide plate.
[0016] As a further description of the above technical solution, a connecting plate is movably connected to the outer surface of the protective shell at the end away from the main circuit shell, and a screw is movably connected to the outer surface of the connecting plate. The screw is fixedly installed on the protective shell by penetrating the connecting plate through its outer surface.
[0017] By adopting the above technical solution and fixing the connecting plate by tightening screws, the front-end powder extraction device can better collect the sample. If the powder extraction device is equipped with an adjustment support device, the connecting plate can be disassembled for better sample collection.
[0018] As a further description of the above technical solution, a fixing tube is welded to the outer surface of the connecting plate, an extension rod is movably connected to the inner surface of the fixing tube, and a handle is fixedly connected to the outer surface of the extension rod.
[0019] By adopting the above technical solution, the fixed tube and the extension rod rotate relative to each other, and the distance between them is adjusted accordingly, which makes it easier for the front-end powder extraction device to collect sampling samples better.
[0020] As a further description of the above technical solution, the cooling guide rod is made of carbon fiber, and the handle is made of soft rubber.
[0021] By adopting the above technical solutions, carbon fiber has high toughness and high temperature conductivity, which facilitates the generation of external low temperatures, while the soft rubber material ensures hand-held comfort.
[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:
[0023] 1. In this application, the working principle of the semiconductor cooling chip is based on the Peltier effect. The current absorbs heat at one end, forming a cold end, and releases heat at the other end, forming a hot end. The semiconductor cooling chip absorbs heat when it corresponds to the temperature conductor side and releases heat when it corresponds to the threaded ring side. The temperature conductor conducts the low temperature to the outside through the cooling guide rod, so that the front end of the powder extraction device is in a cold air state. This reduces the expansion activity of the flour when extracting powder, which is convenient for explosion prevention. The anti-static sheet and grounding wire are also convenient for grounding, avoiding the cause of flour explosion triggered by static electricity generated by air electrons.
[0024] 2. In this application, by unscrewing the tapered tube, the front end of the powder extraction device passes through the threaded ring, and the corresponding threaded groove is screwed into the tapered tube. The inner diameter of the tapered tube decreases from large to small. The outer squeezing clamp rod contracts inward to clamp the front end of the powder extraction device. The side gaskets clamp the powder extraction device on both sides. The powder extraction device is fixed by snapping into the middle surface of the fixing plate. The fixing plate wraps around and fixes the powder extraction device for easy fixation.
[0025] 3. In this application, the connecting plate is fixed by tightening screws, which facilitates better collection of sampling samples by the front-end powder extraction device. If the powder extraction device is equipped with an adjustment support device, the connecting plate can be disassembled for better sample collection and to provide better adjustment space.

[0034] Example:
[0035] Reference Figure 1-5 An explosion-proof protective device for powder extraction during the entire process of noodle making includes a protective shell 1, a circuit body shell 2 welded to the outer surface of the protective shell 1, a semiconductor cooling chip 3 fixedly connected to the inner surface of the circuit body shell 2, a temperature guide plate 4 fixedly connected to the inner surface of the circuit body shell 2, a cooling guide rod 5 corresponding to the inner surface of the temperature guide plate 4, a clamping rod 6 welded to the outer surface of the circuit body shell 2, a threaded ring 7 welded to the inner surface of the circuit body shell 2, and a tapered tube 8 movably connected to the inner surface of the threaded ring 7.
[0036] By unscrewing the conical tube 8, the front end of the powder extraction device passes through the threaded ring 7 and is screwed into the conical tube 8 through the corresponding threaded groove. The inner diameter of the conical tube 8 decreases from large to small, and the outer side squeezes the clamping rod 6 inward to tighten the front end of the powder extraction device. The working principle of the semiconductor cooling chip 3 is based on the Peltier effect. The current absorbs heat at one end to form a cold end and releases heat at the other end to form a hot end. The semiconductor cooling chip 3 absorbs heat when it corresponds to the temperature guide plate 4 and releases heat when it corresponds to the threaded ring 7. The temperature guide plate 4 conducts the low temperature to the outside through the cooling guide rod 5, so that the front end of the powder extraction device is in a cold air state, which reduces the expansion activity of the flour during powder extraction and facilitates explosion prevention.
[0037] Reference Figure 1-5 An antistatic sheet 9 is welded to the outer surface of the tapered tube 8, and a grounding wire 10 is welded to the outer surface of the antistatic sheet 9. The other end of the grounding wire 10 is welded to the outer surface of the protective shell 1.
[0038] The antistatic sheet 9 and grounding wire 10 also facilitate grounding, preventing static electricity generated by air electrons from triggering the flour explosion.
[0039] Reference Figure 1-3 A switch 11 is provided on the outer surface of the protective housing 1, and a power connector 12 is fixedly connected to the outer surface of the protective housing 1.
[0040] Switch 11 facilitates turning on the device to power it on, and power connector 12 facilitates connecting to a power source.
[0041] Reference Figure 1-3 A side gasket 13 is fixedly connected to the inner surface of the protective shell 1, and a fixing piece 14 is fixedly connected to the inner surface of the protective shell 1 at the end away from the main body shell 2 of the circuit.
[0042] The side gasket 13 and the fixing plate 14 facilitate the fixing of the rear end of the powder extraction device. The side gasket 13 clamps the surface of the powder extraction device on both sides. The powder extraction device is inserted into the middle surface of the fixing plate 14, and the fixing plate 14 wraps around and fixes the powder extraction device.
[0043] Reference Figure 1-3 The inner surface of the protective shell 1 is movably connected to a side slide plate 15, and the outer surface of the side slide plate 15 is fixedly connected to an anti-slip groove 16.
[0044] The side slide plate 15 facilitates the placement of the powder extraction device, and the anti-slip groove 16 prevents the side slide plate 15 from being difficult to open due to reduced friction caused by sweat on the hands.
[0045] Reference Figure 1-3 A connecting plate 17 is movably connected to the outer surface of the protective housing 1 away from the main housing 2 of the circuit. A screw 18 is movably connected to the outer surface of the connecting plate 17. The screw 18 passes through the connecting plate 17 and is fixedly installed on the protective housing 1.
[0046] The connecting plate 17 is fixed by tightening the screw 18, which facilitates better collection of samples by the front-end powder extraction device. If the powder extraction device is equipped with an adjustment support device, the connecting plate 17 can be disassembled for better sample collection.
[0047] Reference Figure 1-3 A fixing tube 19 is welded to the outer surface of the connecting plate 17, an extension rod 20 is movably connected to the inner surface of the fixing tube 19, and a handle 21 is fixedly connected to the outer surface of the extension rod 20.
[0048] The fixed tube 19 and the extension rod 20 rotate relative to each other, and the distance between them is adjusted accordingly, so that the front-end powder extraction device can better collect the sample for inspection.
[0049] Reference Figure 1-5 The cooling guide rod 5 is made of carbon fiber, and the handle 21 is made of soft rubber.
[0050] Carbon fiber has high toughness and high temperature conductivity, making it easy to generate external low temperatures, while the soft rubber material ensures comfortable handling.
[0051] The implementation principle of the explosion-proof and protective device for powder extraction during the entire dough-making process described in this application is as follows:
[0052] Before use, the tapered tube 8 is unscrewed, the side slide plate 15 is cut, and the front end of the powder extraction device is screwed into the tapered tube 8 through the threaded ring 7. The outer squeezing clamp 6 retracts inward to clamp the front end of the powder extraction device. The working principle of the semiconductor cooling chip 3 is based on the Peltier effect, also known as the Peltier effect. When direct current passes through a thermocouple composed of N-type and P-type semiconductor materials, the current absorbs heat at one end, forming a cold end; and releases heat at the other end, forming a hot end. The semiconductor cooling chip 3 absorbs heat when it corresponds to the temperature guide plate 4 and releases heat when it corresponds to the threaded ring 7. The temperature guide plate 4 conducts the low temperature to the outside through the cooling guide rod 5, so that the front end of the powder extraction device is in a cold air state. This reduces the expansion activity of the flour during powder extraction and facilitates explosion prevention. The anti-static sheet 9 and grounding wire 10 also facilitate grounding to avoid the cause of flour explosion triggered by static electricity generated by air electrons. The side gasket 13 and fixing plate 14 facilitate the fixing of the rear end of the powder extraction device. The connecting plate 17 is fixed by tightening the screw 18, which facilitates the hand grip 21. The position of the corresponding fixing tube 19 can be adjusted by rotating the extension rod 20, which facilitates better collection of sampling samples by the front powder extraction device. If the powder extraction device is equipped with an adjustment support device, the connecting plate 17 can be disassembled for better sample collection.
[0053] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
