Description

Technical Field

[0001] The invention relates to the technical field of resin processing, in particular to a conveying device for producing unsaturated polymer resin. Background Art

[0002] Unsaturated polymer resin is the most commonly used type of thermosetting resin. It is generally a linear polymer compound with ester bonds and unsaturated double bonds formed by the condensation of unsaturated dibasic acid and diol, or saturated dibasic acid and unsaturated diol. Usually, the polyesterification polycondensation reaction is carried out at 190-220℃ until the desired acid value (or viscosity) is reached. After the polyesterification polycondensation reaction is completed, a certain amount of vinyl monomer is added while it is hot to form a viscous liquid. This polymer solution is called unsaturated polymer resin.

[0003] Temperature and sunlight will affect the storage time of unsaturated polymer resin. It is recommended that the storage temperature should be below 25℃. The lower the temperature, the longer the shelf life of the unsaturated polymer resin, and the higher the temperature, the shorter the shelf life. Unsaturated polymer resin needs to be stored in a sealed container to prevent monomer volatilization loss and external impurities from falling in. The lid of the packaging barrel for storing resin cannot be made of copper or copper alloy. It is recommended to use polypropylene, polyethylene, polyvinyl chloride and other metal materials. In the case of high temperature in summer, it is necessary to avoid direct sunlight on the packaging barrel, but the storage period will still be affected because the gel time of the resin will be shortened a lot in high temperature weather. If it is stable Resins with poor properties may even solidify directly in the packaging barrel. Therefore, if conditions permit, it is recommended to store unsaturated resins in a constant temperature and air-conditioned warehouse at 25°C. If a constant temperature and air-conditioned warehouse is not available, attention should be paid to shortening the storage time of the resin. The shelf life of unsaturated polymer resins is three months in summer and the weather is relatively cold in winter, so the shelf life will be appropriately extended. After the resin exceeds the shelf life, it can still be used normally if it passes the re-inspection. However, the current storage problem of unsaturated polymer resins is that the storage cost is too high, the warehouse area is large, and the energy consumption is high while the energy utilization rate is low in a large area. Therefore, it is necessary to design a conveying equipment for the production of unsaturated polymer resins. Summary of the Invention

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-8 The present invention provides a technical solution: a conveying device for producing unsaturated polymer resin, comprising a resin storage tank 1 and a resin transport tank 2. The resin storage tank 1 is arranged on a transport track 1 3, and the resin transport tank 2 is arranged on a transport track 2 4. The resin storage tank 1 is used to store resin and transport the resin to the resin transport tank 2. The resin transport tank 2 is used as a container for transporting the resin.

[0029] A metal frame 5 is provided between the resin storage tank 1 and the resin transport tank 2 to provide walking and ground space for personnel, so that part of the resin transport process can be manually operated.

[0030] A cavity 16 and a conveying frame 7 are provided on the top of the resin storage tank 1, wherein a hinge-controlled flip cover 18 is provided on the top of the cavity 16, and the top of the flip cover 8 is made of glass, so that the resin inside the resin storage tank 1 can be observed from the outside of the resin storage tank 1. A groove 9 is provided on the top of the conveying frame 7, and a track 3 10 is provided on the inner wall of the groove 9. A baffle 11 is slidably installed on the track 3 10, and the conveying frame 7 is opened and closed by controlling the baffle 11 to slide on the track 3 10. The interior of the conveying frame 7 includes a pressure relief valve 12 and a cavity 2 13, and a motor is provided at the bottom of the baffle 11. The sliding of the baffle 11 can be remotely controlled by the motor or manually controlled. A pressure sensor is provided inside the resin storage tank 1, and the installation position of the pressure sensor is in the adjacent area of ​​the pressure relief valve 12. Since the pressure relief valve 12 is installed on the top of the resin storage tank 1, installing the pressure sensor on the top of the resin storage tank 1 can improve the accuracy of opening and closing the pressure relief valve 12.

[0031] A hinge-controlled flip cover 2 14 is provided on the top of the cavity 2 13. The opening and closing of the flip cover 18 and the cavity 1 6 are fixed and opened by using bolts. Similarly, the opening and closing of the flip cover 14 and the cavity 2 13 are also fixed and opened by using bolts. When opening again, the bolts fixing the flip cover are taken out, and the delivery pipe 15 matching the bolt hole is fixed to the cavity 1 6 and the cavity 2 13 by using the same bolt. The same bolt hole in the cavity is used for two different ways of fixing, and the fixing objects are different, so as to achieve the sealing storage requirements of the resin when it is static and the purpose of resin delivery.

[0032] A rotating rod 16 is provided in the resin storage tank 1, and a main driving member 17 is provided at one end of the resin storage tank 1. A bearing at one end of the rotating rod 16 is provided on the inner wall of the resin storage tank 1, and the other end of the rotating rod 16 is fixedly connected to the output end of the main driving member 17. The rotation of the rotating rod 16 is controlled by controlling the start and stop of the main driving member 17. The main driving member 17 can be a motor. A plurality of metal rods 18 are fixedly installed on the side wall of the rotating rod 16. Each metal rod 18 is made of a heat-conducting material. A hollow layer 19 is provided inside each metal rod 18. A heating plate 20 is provided on the inner wall of the hollow layer 19. Each heating plate 20 is connected to a generator, and the heating plate 20 is independently controlled by the generator.

[0033] Cooling fins 21 are also provided on the inner wall of the hollow layer 19. Each cooling fin 21 is connected to a generator, and the cooling fins 21 are independently controlled by the generator.

[0034] A thermometer 1 22 is also provided in the hollow layer 19, and a plurality of thermometers 23 are provided on the inner wall of the resin storage tank 1. The thermometers 23 are evenly distributed on the inner wall of the resin storage tank 1.

[0035] The main driving part 17 is driven by the equipment system to operate, and the operation of the main driving part 17 drives the rotating rod 16 to rotate, and the rotation of the rotating rod 16 drives the metal rod 18 to rotate, and the rotation of the metal rod 18 stirs the resin in the resin storage tank 1. The equipment system determines the stirring frequency and stirring time according to the amount of resin in the resin storage tank 1. The resin is stirred by the metal rod to ensure that the resin is uniform, and before the resin is transported, it is forced to stir. The stirring time is between 30-60 minutes to ensure that the transported resin is uniform. The thermometer 23 monitors the temperature in the resin storage tank 1 in real time to ensure that the temperature in the resin storage tank 1 is 25 degrees. This temperature has an error temperature value. When the temperature is lower than 25 degrees, the equipment system starts the heating plate 20 and uses the heating plate 20 to heat the resin. When the temperature is higher than 25 degrees, the equipment system starts the cooling plate 21 and uses the cooling plate 21 to cool the resin to ensure that the resin is constant temperature and improve the storage quality of the resin. Due to the presence of the metal rod 18, the heating The energy consumption of the heating plate 20 or the cooling plate 21 works on the metal rod 18 structure. When the equipment system activates the heating plate 20 or the cooling plate 21, it is necessary to simultaneously drive the metal rod 18 to rotate and stir the resin to ensure that the resin temperature is uniform and that the temperature monitoring of the thermometer 2 23 is accurate. The temperature value monitored by the thermometer 1 22 is H, and the temperature value monitored by the thermometer 2 23 is L. The temperature difference between the two is calculated to be M=|HL|. The temperature range of H is set to H1-H2. By monitoring the temperature value of H, whether the sealing of the metal rod 18 is complete is detected. If the H value exceeds the range of H1-H2, it indicates that the sealing of the metal rod 18 is defective. On the premise of ensuring that the sealing of the metal rod 18 is complete, the heating or cooling of the resin is more precisely controlled. M is divided into three levels, M1-M3, a total of three levels. M1 indicates that the temperature difference between the inside and outside of the metal rod 18 is the smallest, and M3 indicates that the temperature difference between the inside and outside of the metal rod 18 is the largest.

[0036] During the resin heating process, if M1 is selected, it means that the temperature value processed and manufactured by the heating plate 20 is very close to the actual temperature of the resin. At this time, the equipment system can turn off the heating plate 20 and continue to heat the resin through the residual heat of the metal rod 18 and the hollow layer 19. The residual heat is sufficient to ensure that the resin reaches 25 degrees within the error range. This method reduces the working time of the heating plate 20 and thus reduces energy consumption. If M2 is selected, it means that the temperature value processed and manufactured by the heating plate 20 is moderately different from the actual temperature of the resin. The equipment system increases the stirring force of the resin by increasing the rotation speed of the rotating rod 16. degrees, prompting the resin temperature to quickly and evenly increase, improving the monitoring accuracy of the thermometer 23, and then improving the accuracy of the M value. The M2 level is to determine a more accurate M value so that the heating plate 20 can be turned off in advance. If it is M3, it means that the temperature value processed by the heating plate 20 is significantly different from the actual temperature of the resin. The rotating rod is kept rotating at a low speed to stir the resin in a low-energy manner. By setting thermometers in different spaces, the actual temperature of the resin and the heating temperature of the resin are accurately calculated. Under the premise of heating the resin to 25 degrees, the resin heating is completed with minimum energy consumption;

[0037] During the resin cooling process, the control of the cooling fins 21 and the stirring control of the rotating rod 16 are consistent with the heating process. By setting thermometers in different spaces, the actual temperature of the resin and the heating temperature of the resin are accurately calculated. Under the premise of cooling the resin to 25 degrees, the resin cooling is completed with minimum energy consumption.

[0038] The cost of converting the constant temperature in the storage room to the constant temperature inside the resin storage tank 1 lies in the design and production of the resin storage tank 1. Compared with traditional resin storage tanks, the cost is higher. However, during long-term use, it not only improves the energy utilization rate, but also improves the accuracy of temperature control of the temperature resin.

[0039] Several buffer bins 24 are provided on the delivery pipe 15, and a curved pipe 25 is provided inside each buffer bin 24. When the resin starts to be delivered, the constant temperature process is started, that is, the thermometer 23 is monitored in real time. The delivery pipe 15 is first sealed and fixed to the cavity 1 6, and the pump 26 provided at the end of the delivery pipe 15 extends into the resin storage tank. A track 4 27 is provided on the inner wall of the end side of the delivery pipe 15, and a lifting plate 28 is slidably installed on the track 4 27. A ground pipe 29 is provided in the middle area of ​​the lifting plate 28. The ground pipe 29 passes through the lifting plate 28, and the pump 26 is fixedly installed at the bottom of the ground pipe 29. The space outside the connection area between the ground pipe 29 and the lifting plate 28 can allow the airflow in the resin storage tank 1 to enter the delivery pipe 15. The constant temperature airflow in the resin storage tank 1 enters the curved pipe 25 through the conveying pipe 15. The airflow performs a temperature balancing process on the bay pipe 25 and the buffer bin 24, that is, ensuring that the temperature in the curved pipe 25 is consistent with the temperature of the resin storage tank 1, avoiding overheating or too low temperature in the curved pipe 25, causing the resin to adhere to the inner wall of the conveying pipe 15 or the curved pipe 25 during transportation. The purpose of maintaining a constant temperature in the buffer bin 24 is to reduce the temperature loss of the curved pipe 25 with the help of the buffer bin 24 with insulation function, thereby reducing the temperature loss during the resin transportation process. The curved curved pipe 25 is provided to not only balance the temperature of the buffer bin 24, but also to increase the resin insulation area and improve the constant temperature efficiency of the resin.

[0040] The other end of the delivery pipe 15 is fixedly connected to the resin transport tank 2 .

[0041] The resin conveying process is to first perform a temperature balancing process for a preset time. After the temperature balancing process is completed, the pump 26 is started by the equipment system to pump the resin, and the resin is conveyed into the conveying pipe 15, passing through multiple buffer bins 24 in sequence until it enters the resin transport tank 2.
