Description

Technical Field

[0001] The invention belongs to the technical field of sponge product production, and in particular relates to a far-infrared enhanced medium sponge production process and production equipment. Background Art

[0002] It is generally believed that far infrared rays can improve blood circulation and metabolism. Existing far infrared dielectric materials cannot well reflect the characteristics of far infrared rays. Good far infrared dielectric materials should be able to release far infrared rays of different intensities according to the ambient temperature, rather than having a fixed emissivity and radiation intensity. For this reason, our inventors have designed a Yuanneng wide-band far infrared enhanced dielectric cotton, which has the characteristics of emitting far infrared rays with a wide amplitude, high intensity, and good sustainability. During the research process of the dielectric cotton, it was found that the existing conventional production process has a high cost and is not easy to promote the product, so it is necessary to improve the process to a certain extent.

[0003] In the corresponding process, the configured energy powder needs to be mixed with other materials. This step is extremely important for the forming of the medium sponge, so a mixing tank with good stirring is required.

[0004] my country's patent CN201921997916.3 discloses a stirring tank, including a base and a stirring tank body; the stirring tank provided by the utility model, by arranging a heating and dissolving box between the feed hopper and the stirring tank body, can first dissolve the powder material preliminarily after mixing and heating, thereby increasing the adhesion and binding force of the raw materials, making the subsequent stirring more uniform, and also saving stirring time and improving work efficiency; by arranging a first water spray pipe in the stirring tank body, the liquid is evenly sprayed into the stirring tank body through the water spray pipe, thereby improving the mixing efficiency; by arranging a second water spray pipe on the tank cover, it can be used to realize automatic cleaning of the tube wall of the stirring tank body after the stirring is completed; the stirring tank body in the present application is fixed between two brackets by a support shaft, and the material can be taken out by flipping the stirring tank body after the stirring is completed. The overall weight of the stirring tank body is supported by the bracket, the force required for flipping is small, and the material is convenient and quick to take out.

[0005] There are a large number of existing mixing tank technologies, which can achieve rapid mixing of powder and liquid, but there are still some deficiencies in the mixing process of medium sponge: First of all, when mixing the medium cotton raw material, the energy powder needs to be fully mixed with the semi-foamed polyurethane foam raw material. The polyurethane foam material has a certain density, so when the powder falls on the foam material, it is easy to float on the surface of the foam material. The conventional stirring rod has insufficient stirring effect on the foam material, and it is unable to quickly sink and fuse it, which prolongs the overall mixing time and affects the mixing quality.

[0006] Secondly, when feeding, the existing mixing tank will discharge the powder in large quantities to one location, which is very likely to cause powder accumulation, and the mixing rod cannot sink the powder quickly, thus further aggravating the low mixing efficiency. Summary of the invention

[0007] In order to overcome the deficiencies of the prior art, the present invention provides a far-infrared enhanced dielectric sponge production process and production equipment. The present invention improves the quality of the finished product and the overall cost of the dielectric sponge through process improvements, and cooperates with the arrangement of structures such as a stirring blade and a conical hole, a fan wheel and a material distribution component inside the production equipment, so that during the mixing process of the materials, the powder can be relatively evenly sprinkled into the polyurethane foam material over a large area, reducing the difficulty of mixing, and the equipment can also quickly sink the powder and mix it into the polyurethane foam material, effectively improving the quality of the finished product of the dielectric sponge.

[0008] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a far-infrared enhanced medium cotton production equipment, comprising a tank body and a tank cover, the bottom of the tank body is in a stepped cone shape, a detachable tank cover is provided on the upper end surface of the tank body, a first feed pipe is provided on one side of the upper end surface of the tank cover, a material distribution component is provided in the first feed pipe, an inner liner is provided on the inner wall of the tank body, and a discharge valve port is provided on the bottom end surface of the tank body; A rotating shaft, the rotating shaft is rotatably arranged at the center of the inner container, and a detachable spiral stirring shaft is arranged outside the rotating shaft; A first bending frame, wherein a plurality of the first bending frames are arranged outside the spiral stirring shaft, the plurality of the first bending frames rotate synchronously with the spiral stirring shaft, and a second bending frame having the same shape as the inner wall of the inner container is connected to one side of the first bending frame; Agitating blades, wherein a plurality of the agitating blades are connected between the second bending frame and the first bending frame in an inclined manner, and each of the agitating blades is provided with a plurality of tapered holes; Insulation pipes, a plurality of the insulation pipes are wound on the outer circumferential surface of the tank body, a connecting inner pipe is arranged between the plurality of insulation pipes, and a temperature detector is arranged above the insulation pipes at the bottom of the tank cover.

[0009] Through the setting of the spiral stirring shaft and the overall shape of the tank, the equipment can fully stir a small amount of material and the powder sunk to the bottom can be rolled up again, thereby improving the mixing quality; through the setting of the first bending frame and the second bending frame and the stirring knife and the tapered hole, the powder and the polyurethane foam material can be squeezed in all directions, thereby effectively improving the mixing quality, and the setting of the insulation pipe ensures that the overall temperature inside the equipment can be effectively controlled during mixing.

[0011] The arrangement of the support frame and the fixed platform improves the overall stability of the equipment, and the arrangement of the first vibrator improves the mixing effect and reduces material residue during discharge.

[0012] In the above-mentioned far-infrared enhanced medium cotton production equipment, a second feed pipe is arranged on one side of the outer cylindrical surface of the driving structure, a removable second sealing end cover is arranged on the outer side of the second feed pipe, and a second injector is arranged on the outer end surface of the second sealing end cover; The first sealing end cover is arranged on the outer end surface of the first feed pipe, and a plurality of first injectors are arranged on the end surface of the first sealing end cover.

[0013] Through the arrangement of the second injector and the first injector, the equipment can complete the addition processing of multiple materials in different stirring time periods.

[0014] In the above-mentioned far-infrared enhanced medium cotton production equipment, the material distribution component includes: A conical cover, the conical cover is arranged at the center of the first feed pipe, a plurality of sieve plates are rotatably arranged on the conical surface of the conical cover, and a plurality of sieve holes are arranged on the sieve plates; A first conical ring, the first conical ring is arranged on the inner surface of the first feed pipe in an inclined shape as a whole; The second conical ring is arranged outside the conical cover, and a plurality of elastic strips are connected between the second conical ring and the first conical ring.

[0015] Through the arrangement of the conical cover, the first conical ring and the second conical ring, the powder uniformly poured into the first feed pipe can be uniformly spread and distributed, so that the powder can be scattered over a relatively large area on the polyurethane foam material, reducing the difficulty of mixing.

[0016] In the above-mentioned far-infrared enhanced medium cotton production equipment, the material distribution component also includes: A support ring, the support ring is fixedly arranged on the bottom of the first feed pipe, a second vibrator is arranged on the upper end surface of the support ring, a connecting platform is connected to the output end of the second vibrator, and a conical cover is fixedly connected to the connecting platform; Elastic sealing rings: a plurality of elastic sealing rings are arranged between the second vibrator and the connecting platform.

[0017] By arranging the second vibrator and the elastic sealing ring, the powder can be quickly scattered downwards through multiple vibrations, thereby improving the efficiency of discharging.

[0018] In the above-mentioned far-infrared enhanced medium cotton production equipment, a rotating connecting plate is connected between the first bending frame and the second bending frame below the first feed pipe, and multiple transmission shafts are rotatably arranged on the end surface of the rotating connecting plate, and fan wheels are connected to the upper and lower ends of the multiple transmission shafts.

[0019] Through the setting of the fan wheel and the transmission shaft, the equipment can form a more complex vortex on the uppermost layer of the polyurethane foam material, so that the powder can sink into the polyurethane foam material quickly.

[0020] In the above-mentioned far-infrared enhanced medium cotton production equipment, the bottommost insulation pipe is externally connected to a drain valve pipe, and the topmost insulation pipe is externally connected to a liquid inlet valve pipe.

[0021] By arranging the discharge valve pipe and the inlet valve pipe, the specific temperature inside the tank can be effectively controlled when stirring.

[0022] A production process of far-infrared enhanced dielectric cotton, the process flow is as follows: S1: Select aluminum oxide, zinc oxide, silicon oxide, titanium oxide, zirconium oxide and platinum with a purity of 95.50-99.99% and grind them into a size below 50 nanometers; S2: fully mix the various ground powders according to the proportion to make energy powder; S3: adding the energy powder to the polyurethane foaming raw material and stirring for more than 2 hours to obtain the energy polyurethane foaming material; S4: Add the Yuanneng polyurethane foam material into the foaming mold to shape it, and obtain the Yuanneng wide-width far-infrared reinforced dielectric cotton; The stirring rate of the equipment in S3 is 1250-1800 rad / h, and the temperature during stirring in S3 is 20-30 degrees Celsius.

[0023] The existing process only requires four steps to complete the production of medium cotton, which simplifies the process, reduces production costs and improves production efficiency.

By specifically controlling the proportions, the molding quality of the dielectric sponge can be effectively improved.

[0026] In summary, compared with the prior art, the beneficial effects of this solution are: (1) The present invention arranges the spiral stirring shaft, the first bending frame, the second bending frame and the impeller, so that the equipment can not only mix a small amount of materials, thereby improving the applicability of the equipment, but also perform multiple sufficient extrusion and mixing processes on the foamed polyurethane foam material and the powder, thereby effectively improving the molding quality and molding effect of the medium sponge; (2) The present invention uses the rotating connecting plate, the transmission shaft, the impeller, etc. to enable the equipment to form a more complex vortex on the top of the material when the powder is just sprinkled into the tank, so that the powder can sink quickly and be mixed into the material, effectively improving the mixing efficiency; (3) The present invention arranges the conical cover and the second conical ring as well as the second vibrator and the sieve plate to make the powder that would otherwise be piled up and discharged dispersed relatively evenly and scatter downward, which can effectively reduce the accumulation of powder on the foam raw material, reduce the difficulty of mixing, and improve the efficiency of mixing; (4) The present invention improves the process and sets the formula, so that the medium cotton not only has the characteristics of wide far infrared wave amplitude, high intensity and good sustainability, but also greatly shortens the overall production process, reduces production costs and improves production efficiency.

This arrangement makes it difficult for the material to adhere to the inner wall during stirring, which is convenient for discharge. At the same time, the equipment can also fully stir a small amount of material, reducing the occurrence of uneven stirring when the material is insufficient. A discharge valve port 17 is provided at the center of the bottom circle of the tank body 10, and a switch valve is provided inside the discharge valve port 17, which can discharge the mixed material inside the tank body 10 to the outside, and an exhaust valve pipe 29 is provided on the outer circular surface of one side of the discharge valve port 17. Before the equipment is discharged, the exhaust valve pipe 29 can discharge the hot air inside the tank body 10 to the outside, reducing the occurrence of scalding of the staff. This is a prior art, and this scheme will not be elaborated in detail.

[0031] Reference Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 A tank cover 12 fixed by a flange and bolts is arranged at the upper end surface of the tank body 10, and a first feed pipe 24 with an integral pipe bent upward is arranged on one side of the outer surface of the tank cover 12. The first feed pipe 24 mainly pours various types of powders into the tank body 10 respectively. A detachable first sealing end cover 18 is arranged at one end of the outer side of the first feed pipe 24. A plurality of first injectors 20 are arranged on the end surface of the first sealing end cover 18. Each first injector 20 can be connected to a feeder on the outside. A plurality of first injectors 20 can be connected to a certain number of feeders, so that various types of powders can be poured separately. A material distribution component is arranged at the bottom of the first feed pipe 24, and the material distribution component will distribute the powder in a larger area. Sprinkle it into the interior of the tank body 10 to reduce the situation of concentrated accumulation of material discharge and improve the mixing effect. A second feeding pipe 25 bent outward is also provided on the outer circular surface of the other side of the tank cover 12, and a second sealing end cover 19 is provided on the outer end face of the second feeding pipe 25. A second injector 21 is provided on the outer end face of the second sealing end cover 19. The second injector 21 is externally connected to a feeder of polyurethane foam material. The second injector 21 can inject the polyurethane foam material into the second feeding pipe 25, and then discharge it into the interior of the tank body 10 through the second feeding pipe 25. In the above scheme, the second injector 21, the first injector 20 and the feeder are existing technologies, and this scheme will not be elaborated in detail, and is used to complete precise feeding processing.

[0032] Reference Figure 1 and attached Figure 4A driving structure 11 is arranged at the center of the upper end surface of the tank cover 12. The driving structure 11 is composed of an explosion-proof motor, a reducer, etc., which is the prior art and will not be elaborated in detail in this scheme. A rotating shaft 23 is connected to the tank body 10 at the output end of the driving structure 11. One end of the bottom of the rotating shaft 23 is only separated from the upper side of the bottom of the tank body 10. A spiral stirring shaft 28 is arranged on the outer circumferential surface of the rotating shaft 23. The spiral stirring shaft 28 is spirally upward as a whole. When multiple materials are poured into the tank body 10, the driving structure 11 can drive the rotating shaft 23 to rotate, thereby driving the spiral stirring shaft 28 to rotate, so that the materials can be stirred. Since the blades of the spiral stirring shaft 28 are spirally upward, a part of the powder that sinks to the bottom of the tank body 10 due to weight can be driven to roll upward, so that the mixing process can be completed again, the occurrence of dead angles can be reduced, and the mixing quality can be improved.

[0033] Reference Figure 4 , Attachment Figure 5 and attached Figure 6 A connecting sleeve 36 fixed by fastening bolts is provided on the top outer circumferential surface of the spiral stirring shaft 28, and a plurality of first bending frames 32 bent and deformed downward are provided on the outer circumferential surface of the connecting sleeve 36. The plurality of first bending frames 32 are arranged on the outer side of the spiral stirring shaft 28, and a second bending frame 34 is connected to the bottom of the first bending frame 32. The overall bending shape of the second bending frame 34 is the same as the inner wall cross-section of the inner tank 22. The outer end surface of the second bending frame 34 is basically in contact with the inner wall surface of the inner tank 22, and the two sides of the second bending frame 34 are conical. When the spiral stirring shaft 28 is rotating, the spiral stirring shaft 28 will also drive the connecting sleeve 36 and the plurality of first bending frames 32 on the connecting sleeve 36 to rotate, thereby driving the plurality of second bending frames 34 to rotate, so that a large area of ​​stirring can be formed on the outside of the spiral stirring shaft 28, while scraping part of the material adhering to the inner wall of the inner tank 22, so that it can be re-mixed and processed to improve the mixing effect.

[0034] Reference Figure 5 and attached Figure 6A plurality of inclined stirring blades 33 are connected and arranged between the first bending frame 32 and the second bending frame 34. The stirring blades 33 are inclined upward in the clockwise direction of the spiral stirring shaft 28. A plurality of tapered holes 35 are arranged on the end surface of the stirring blades 33. The plurality of tapered holes 35 are arranged in a shape that the clockwise direction of the spiral stirring shaft 28 is the large hole end and the counterclockwise direction is the small hole end. This arrangement increases the contact area between the stirring blades 33 and the material when the second bending frame 34 and the first bending frame 32 drive the plurality of stirring blades 33 to stir, so that the material can be squeezed better, so that the polyurethane foam material can be dispersed and mixed with the powder, and the polyurethane The foaming material and various powders can be squeezed and flow toward the multiple tapered holes 35. Since the tapered holes 35 are arranged in a tapered shape as a whole and the large mouth is arranged in a clockwise direction, the material will be squeezed and flow into each tapered hole 35, so that the polyurethane foaming material and various powders can be squeezed and fused for the second time during the flow process, which effectively improves the mixing effect. In this solution, there are no excessive restrictions on the connection shape between the stirring blade 33 as a whole and the first bending frame 32 and the second bending frame 34. The figure only shows the state of horizontal connection, and an inclined connection can also be performed to expand the stirring contact effect with the material. The specific setting can be based on actual conditions.

[0035] Reference Figure 1 In order to ensure the overall stability of the equipment, a plurality of fixing platforms 14 formed by welding a plurality of rib plates are evenly arranged along the circumferential direction on the outer circumferential surface of the tank body 10, and a support frame 13 is arranged on the bottom end surface of the fixing platform 14. The support frame 13 is in a groove shape as a whole, and a plurality of reinforcing ribs are arranged inside. The bottom end surface of the support frame 13 abuts against the ground. Through the arrangement of a plurality of support frames 13 and the fixing platform 14, the equipment as a whole can be stably supported and the fixing quality is improved.

[0036] Reference Figure 1 , Attachment Figure 4 , Attachment Figure 7 and attached Fig.11When the equipment is stirring, the inside of the tank body 10 needs to maintain a certain temperature and humidity. A temperature detector 26 and a humidity detector 27 are arranged on the inner arc surface of the tank cover 12, which can respectively detect the temperature and humidity inside the tank body 10, so that the material can complete the mixing process under a certain environment. A plurality of insulation tubes 16 are wound on the outer circumferential surface of the tank body 10. The inside of the plurality of insulation tubes 16 is hollow, and the plurality of insulation tubes 16 are interconnected through a plurality of connecting inner tubes 51. The top insulation tube 16 is connected to the outside with a liquid inlet valve tube 31, and the bottom insulation tube 16 is connected to the outside with a liquid discharge valve tube 30. When the material is stirred inside the tank body 10, the staff can inject a refrigerant or heating liquid of a certain temperature into the insulation tube 16 through the liquid inlet valve tube 31. The liquid will flow in the multiple connected inner tubes 51 and the insulation tube 16 in sequence, so that the temperature can be transferred to the tank body 10, so that the internal temperature of the tank body 10 can be adjusted. The flowing liquid can finally be discharged to the outside through the drain valve tube 30 to complete the heat conduction or refrigeration treatment. In this scheme, a device for adjusting the humidity inside the tank body 10 and other control elements should also be set on the outer arc surface of the tank cover 12. These are existing technologies themselves and will not be elaborated in this scheme.

[0037] Reference Figure 7 , Attachment Figure 8 and attached Fig. 9 In order to ensure that the powder can be relatively dispersed and sprinkled into the interior of the polyurethane foam material, a material distribution component is arranged inside the first feed pipe 24, and the material distribution component includes a support ring 49 arranged at the bottom of the first feed pipe 24, and a second vibrator 47 is fixedly arranged on the end face of the support ring 49. A connecting platform 46 is connected to the vibration output end of the second vibrator 47, and a conical cover 43 is fixedly arranged at the upper end face of the connecting platform 46. The top end face of the conical cover 43 is conical. A first conical ring 40 inclined downward is arranged on the inner wall surface of the first feed pipe 24 outside the conical cover 43, and a plurality of elastic strips 41 inclined downward are arranged on the inner circumferential surface of the first conical ring 40. A second conical ring 42 is connected between the plurality of elastic strips 41, and the inner circumferential surface of the second conical ring 42 is basically attached to the outer circumferential surface of the conical cover 43. In this scheme, a grid sieve hole will be formed between the plurality of elastic strips 41, and the second conical ring 42 and the elastic strips 41 are made of high temperature resistant elastic rubber material and have a certain elasticity.

[0038] Reference Figure 7 , Attachment Figure 8 and attached Fig. 9When the powder enters the first feeding pipe 24, a part of the powder will be directly screened relatively evenly by the grid sieve holes formed by the multiple elastic strips 41 and fall into the tank body 10, and the other part will be blocked by the conical cover 43 and the annular first conical ring 40 and the second conical ring 42. At this time, the second vibrator 47 will be started, and the output end of the second vibrator 47 will drive the connecting platform 46 to vibrate to a certain extent, thereby driving the conical cover 43 above the connecting platform 46 to vibrate, thereby vibrating the powder on the conical cover 43, so that the powder can flow downward and diffuse and fall evenly along the conical surface of the conical cover 43. A plurality of guide grooves 50 are arranged on the outer circumferential surface of the conical cover 43, and the plurality of guide grooves 50 can guide the powder so that the powder can fall better. The inner circular surface of the face ring 42 basically fits the outer surface of the conical cover 43, so the vibration of the conical cover 43 will also impact the second conical face ring 42, thereby vibrating the second conical face ring 42 and the elastic strip 41. The elastic strip 41 will transmit part of the vibration to the first conical face ring 40, so that the powder that falls to the elastic strip 41 and the second conical face ring 42 and other positions can be shaken off, so that it can be slowly and evenly scattered downward, effectively avoiding the occurrence of concentrated accumulation and falling, and improving the uniformity of mixing. In this solution, in order to prevent powder from entering the output end of the second vibrator 47, an elastic sealing ring 48 made of elastic material is arranged between the connecting platform 46 and the second vibrator 47. The elastic sealing ring 48 will not affect the vibration of the connecting platform 46 and can prevent dust from entering.

[0039] Reference Figure 8 A driving motor 45 is provided at the upper end surface of the connecting platform 46, and the output end of the driving motor 45 extends out to the end surface of the conical cover 43. A plurality of sieve plates 44 are connected and provided at the output end of the driving motor 45, and each sieve plate 44 is attached to the outer surface of the conical cover 43. The sieve plate 44 is attached to one end of the outer surface of the conical cover 43 and is provided with a plurality of sieve holes. When the conical cover 43 is shaking the powder, the output end of the driving motor 45 can drive the plurality of sieve plates 44 to rotate, so that the powder on the conical cover 43 can be moved so that the powder can fall downward stably. The setting of the plurality of sieve holes on the sieve plate 44 can reduce the amount of powder to be moved at a single time and slow down the discharge speed on the one hand, and can squeeze and crush a part of the powder bonded by moisture to disperse it and ensure the discharge effect on the other hand. Embodiment 2:

[0040] Reference Figure 5 and attached Figure 6A far-infrared enhanced medium cotton production equipment. In order to ensure that the powder can be quickly mixed into the polyurethane foam material in a short time, a rotating connecting plate 37 is connected at the top of the first bending frame 32 and the second bending frame 34. A plurality of transmission shafts 38 are rotatably arranged on the end surface of the rotating connecting plate 37, and a fan wheel 39 is arranged on the upper and lower end surfaces of each transmission shaft 38.

[0041] When the first bending frame 32 and the second bending frame 34 are rotating to stir the material, the rotating connecting plate 37 will also be driven to rotate, thereby driving the multiple transmission shafts 38 and the fan wheels 39 to rotate. Since the multiple fan wheels 39 are distributed in a vertical direction, during the rotation process, the multiple fan wheels 39 will also rotate due to contact with the material, thereby forming a secondary vortex in the large-area vortex generated by the first bending frame 32 and the spiral stirring shaft 28. When powder is sprinkled at the first feed pipe 24, the multiple rotating fan wheels 39 generate small vortices that can quickly break up the powder, so that it can be quickly mixed into the polyurethane foam material and will not float on the surface for a long time, thereby improving the mixing efficiency. Embodiment three:

[0042] Reference Figure 4 and attached Fig.10 , a far-infrared enhanced medium cotton production equipment, the polyurethane foam material is relatively thick as a whole, so the powder cannot be quickly mixed into the polyurethane foam material, so a first vibrator 15 is arranged on the end surface of multiple fixed platforms 14, and the output end of the first vibrator 15 extends into the tank body 10 and abuts against the wall surface of the inner tank 22. When the tank body 10 is stirred inside, the multiple first vibrators 15 can vibrate the inner tank 22, thereby vibrating the material in the inner tank 22, thereby improving the mixing quality of the material. When discharging the material inside the tank body 10, the first vibrator 15 can also generate vibration, so that the material formed in the tank body 10 can be discharged smoothly to the outside, reducing the residual phenomenon of the material. Embodiment 4:

[0055] Experimental verification 1 Experimental description: Using the same refrigerator and the same freezer location, the changes in refrigeration effect are observed by comparing the temperature drop between when the Yuanneng active cotton sheet is placed and when it is not.

[0056] Experimental equipment: a household refrigerator (Gree); a CNC temperature detection device; a Yuanneng active cotton sheet 30*30*1CM; a notebook and a pen.

[0057] Specific experimental methods: (I) Prepare an unstarted refrigerator, connect a temperature detection probe to the freezer layer of the refrigerator, and connect it to an external digital temperature monitoring device; (II) Start the refrigerator and first conduct a cooling experiment with non-energy active cotton, which is the experimental data of Group A in the table below. Record the time required for the temperature in the refrigerator to drop to different temperature points.

[0058] (III) After the experiment, turn off the power, open the refrigerator door, and let the refrigerator return to normal temperature; (IV) Place the Yuanneng active cotton sheet on the frozen test layer, which is the experimental data of Group B in the table below; (V) Start the refrigerator and record the time required for the temperature inside the refrigerator to drop to the same temperature as the non-energy active cotton test.

[0059] 6. Tabulate the experimental results for comparative analysis.

[0060] The specific experimental data are recorded in the following table

[0061] Summarize: Through this experiment, we can see that Yuanneng far-infrared active cotton can significantly improve the refrigeration efficiency, especially at ultra-low temperatures of minus 20 degrees Celsius, the advantage is very obvious. Since minus 20 degrees Celsius is basically the temperature requirement of the cold chain, it can be seen that Yuanneng far-infrared active cotton has broad prospects for energy-saving applications in the cold chain.

[0062] Experimental verification 2 Experimental description: In the same space, with the same heater, the change in heating effect is observed by adding energy cotton sheets to the air inlet of the heater.

[0063] Experimental equipment: one 2000W Airmate heater; A thermometer and hygrometer; A stopwatch; An empty room of a fixed size with a glass observation window on one side of the room. The specific dimensions of the room 3m*1.55m*2.8m, volume 13.02 cubic meters.

[0064] Specific experimental methods: First, place the thermo-hygrometer in the room and record the starting temperature and humidity of the room; Place the Airmate heater without Yuanneng active cotton in the inner corner of the room, turn on the power, adjust to the maximum wind speed of the hot air gear, and start the synchronous stopwatch.

[0065] The operator exits the room and closes the door.

[0066] Record the time it takes for the indoor temperature to rise by 7 degrees (to around 20 degrees Celsius).

[0067] After the experiment, turn off the heater, open the door, and wait until the indoor temperature and humidity return to the initial temperature before conducting the comparative experiment. The comparative experiment uses the same heater, but adds Yuanneng active cotton at the air inlet. Follow the same steps to conduct the experiment.

[0068] To ensure the objectivity of the experiment, the experiment was repeated at least three times.

[0069] The specific experimental data are recorded in the following table

[0070] Summary: Through this experiment, we can see that by modifying the air inlet of the heater with energy active cotton, the heating efficiency can be significantly improved, and repeated experiments have proved that this effect is clear and reliable.

[0071] Experimental verification 3

[0072] Summary and analysis: 1. By comparing the data of the experimental group and the control group after high temperature treatment at 160℃ and 180℃, it can be seen that almost all the change data of the experimental group are less than those of the control group, which indicates that the experimental group has better tolerance to high temperature than the control group.

[0073] 2. By comparing the data of the experimental group and the control group after high-temperature treatment at 160℃ and 180℃, it can be seen that only the tear strength and tensile strength data after treatment at 160℃ changed more in the experimental group than in the control group, and these two data are positive data, and the larger the value, the better the material performance of the experimental group.

[0074] 3. Another important indicator for measuring sponge performance is the compression deformation rate. Through data comparison, it can be found that the experimental group has less changes after high temperature resistance, and the absolute value of the compression deformation rate is also much less than that of the control group.
