Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying equipment technology, and in particular to a continuous heating and microwave sterilization and insecticidal conveying device. Background Technology
[0002] An electric screw conveyor is a mechanical device that uses a motor to drive a screw blade to rotate, and the screw blade pushes the material to transport it. It is mainly used for conveying powders, granules, and small lumps, and can transport materials horizontally, inclined, or vertically. In the food, pharmaceutical, and agricultural industries, there is a need to heat or microwave raw materials for sterilization and insect control (for example, in the food industry, sterilizing dried fennel, star anise, Sichuan peppercorns, and chili peppers to remove excessive levels of E. coli, mold, and pathogens; in agriculture, sterilizing and insect-controlling rice flour, paddy rice, peanuts in their shells, oat flakes, and raw oat flakes, as well as sterilizing and insect-controlling raw materials for edible fungi).
[0003] In existing technologies, electric screw conveyors and electric heating / sterilization / insecticide mechanisms, or microwave sterilization / insecticide mechanisms, are three separate sets of equipment. This means that while the electric screw conveyor is conveying the corresponding material, it cannot simultaneously perform electric heating and microwave sterilization / insecticide processes. Consequently, production efficiency is low, and production costs are increased (usually, one set of electric conveyors feeds the material into the electric heating or microwave sterilization / insecticide equipment, and after sterilization / insecticide treatment, the material is output to the next process via another electric conveyor). Therefore, it is very necessary to provide a device that combines material conveying with electric heating, microwave sterilization, and insecticide functions. Utility Model Content
[0004] To overcome the shortcomings of existing electric screw conveyors, electric heating sterilization and insecticidal mechanisms, and microwave sterilization and insecticidal mechanisms, which are separate from each other and cannot perform sterilization and insecticidal operations simultaneously with material transport, this utility model provides a continuous heating and microwave sterilization and insecticidal conveying device that, under the combined action of the relevant mechanisms, can sterilize and kill materials simultaneously with microwave and electric heating, thereby improving work efficiency and saving production costs.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A continuous heating and microwave sterilization / insect-killing conveying device includes an electric spiral conveyor with a conveying pipe, a drive shaft, spiral blades, and a motor reduction mechanism; microwave sterilization equipment; an electric heating fan; a voltage regulating device; and a fixed cylinder. The conveying pipe has multiple openings at intervals from front to back at both ends. A glass plate is fixedly installed on the outside of each opening. Multiple sets of microwave sterilization equipment are installed, each set fixedly installed on the outside of the multiple openings in the conveying pipe. The drive shaft is a hollow structure with multiple air vents at intervals on its surface. The front of the fixed cylinder... Bearings are fixedly installed on the rear end. The outer front end of the drive shaft is fixedly installed in the inner ring of the bearing at the rear end of the fixed cylinder. The rear end of the fixed cylinder is fixedly installed on the outer front end of the conveying pipe. The motor reduction mechanism is fixedly installed on the outer front end of the fixed cylinder. The rear side of the rotating shaft of the motor reduction mechanism and the front side of the drive shaft are fixedly installed together. An air inlet pipe is fixedly installed on the upper end of the fixed cylinder. The upper end of the air inlet pipe is fixedly connected to the air outlet pipe of the electric heating fan. The electric heating fan is fixedly installed on the side end of the electric screw conveyor. The power output terminal of the voltage regulating device is electrically connected to the power input terminal of the electric screw conveyor.
[0007] Furthermore, the multiple microwave sterilization devices at both ends of the delivery pipe are installed in a staggered manner, with each pair of horizontally distributed microwave sterilization devices being staggered.
[0008] Furthermore, the transmitter heads of the multiple microwave sterilization devices are respectively attached to the outer sides of multiple glass plates.
[0009] Furthermore, a sealing ring is installed between the inner and outer rings of the bearing.
[0010] Furthermore, the inner surface of the fixed cylinder of the drive shaft has multiple air inlets.
[0011] Compared with existing technologies, the advantages of this invention are as follows: Through the combined action of related structures, this invention integrates multiple functions including conveying, electric heating, microwave sterilization, and insecticidal effects. The equipment is relatively compact and easy to use. The hot air blower outputs hot air through a fixed cylinder and the air outlet of the drive shaft while the material is being conveyed via the rotating shaft. Simultaneously, multiple microwave sterilization devices generate microwaves that act on the material, achieving continuous sterilization and insecticidal effects. This improves work efficiency and saves production costs. In summary, this invention has good application prospects. Attached Figure Description

[0014] Figure 2 , 3 This is a partial structural schematic diagram of the present invention. Detailed Implementation
[0015] Figure 1 , 2 As shown in Figure 3, a continuous heating and microwave sterilization and insecticidal conveying device includes an electric spiral conveyor (power 5KW) with a conveying pipe 1, a drive shaft 2 and spiral blades 3, a motor reduction mechanism 4 and other necessary components; a microwave sterilization device 5 (model BJ2211NS, power 1KW per set); and an electric heating fan (…). Figure 1 , 2 (Not shown in the diagram, power 6KW), voltage regulating device 6 (model TDGC2, input AC 220V, output 0-220V continuously adjustable AC power supply), fixed cylinder 7; the conveying pipe 1 has five openings 101 at intervals on the left and right ends and from front to back, and a tempered glass plate 102 is fixedly installed on the outside of each opening through a hollow rectangular fixing plate. There are ten sets of microwave sterilization equipment 5, and each set of microwave sterilization equipment 5 is fixedly installed on the outside of each opening 101 of the conveying pipe; the drive shaft 2 is a hollow structure with closed front and rear ends, and the surface of the drive shaft 2 has multiple air vents 21 at intervals. A bearing 71 is fixedly installed in the middle of the front and rear ends of the fixed cylinder 7, and the outer front end of the drive shaft 2 (fixed in the inner ring of the bearing in the middle of the rear side of the conveying pipe) is led out from the outer front end of the middle front part of the conveying pipe 1 and fixedly installed in the inner ring of the bearing 71 at the rear end of the fixed cylinder. The front part is located inside the rear end of the fixed cylinder 7. The rear end of the fixed cylinder 7 is fixedly installed on the front outer end of the conveying pipe 1. The motor reduction mechanism 4 is fixedly installed on the front outer end of the fixed cylinder 7, and the middle part of the rotating shaft of the motor reduction mechanism 4 is fixedly installed in the inner ring of the bearing 71 at the front end of the fixed cylinder 7. The rear part of the rotating shaft is located inside the front end of the fixed cylinder 7. The rear part of the rotating shaft and the front part of the transmission shaft 2 are fixedly installed together. An air inlet pipe 72 that communicates with its interior is fixedly installed in the middle of the upper end of the fixed cylinder 7. The upper end of the air inlet pipe 72 is connected to the air outlet pipe of the electric heating fan through a pipe. The electric heating fan is fixedly installed on the front right end of the electric screw conveyor. The power input terminals of the voltage regulating device 6 (installed in the electrical control box of the electric screw conveyor) and the ten sets of microwave sterilization equipment 5 are connected to the two poles of the AC 220V power supply through wires. The power output terminal of the voltage regulating device 6 is connected to the power input terminal of the motor reduction mechanism 4 of the electric screw conveyor through wires.
[0016] Figure 1 , 2As shown in Figure 3, five sets of microwave sterilization devices 5 are installed from front to back at the left and right ends of the conveying pipe 1, with the two sets of microwave sterilization devices 5 arranged laterally on each side being staggered. The transmitter heads of the ten sets of microwave sterilization devices 5 are respectively sealed and fitted to the outer sides of the ten glass plates 102 (the outer end of the opening of the conveying pipe 1 has multiple threaded holes, and the microwave sterilization devices 5 and fixing plates are screwed into the threaded holes by bolts and then installed at the outer end of the opening). Sealing rings are installed between the inner and outer rings of the front and rear bearings of the bearing 71 (to prevent hot air from escaping). The front end of the drive shaft 2 has multiple air inlets 22 located on the inner surface of the fixed cylinder.
[0017] Figure 1 , 2 As shown in Figure 3, this new type of equipment integrates multiple functions such as conveying, electric heating, microwave sterilization, and insecticidal functions through the combined action of related structures. The equipment is relatively compact and easy to use. When the electric screw conveyor is working, the motor reduction mechanism 4 drives the screw blades 3 to rotate via the transmission shaft 2. The screw blades 3 push the material (granular or powdery, etc.) for conveying, so that the material can enter from the feed inlet 103 and exit from the discharge outlet 104 of the conveying pipe. When the ten sets of microwave sterilization equipment 5 are working, microwaves are generated and act on the material in the conveying pipe through the glass plate 102 to sterilize and kill insects. Since the five sets of microwave sterilization equipment 5 installed on the left and right ends of the conveying pipe 1 from front to back are staggered, the ten sets of microwave sterilization equipment 5 can continuously sterilize and kill insects on the material in the conveying pipe as much as possible. After the electric heating fan is powered on, the hot air output enters the fixed cylinder 7. Then, the hot air (around 110℃) enters the drive shaft 2 through the air inlet pipe 72 and air inlet hole 22, and is discharged from several air outlet holes 21 distributed on the front and rear surfaces of the drive shaft, heating and sterilizing the material in the conveying pipe. After sterilization, the material is discharged from the discharge port 104 of the conveying pipe along with the hot air (to prevent powdery material from being blown into the air by the hot air, a cloth bag is usually placed at the lower end of the discharge port as a material collection mechanism) into the material collection mechanism. In this new invention, by adjusting the voltage of the output power supply of the voltage regulating device 6, the motor speed of the electric screw conveyor can be adjusted, thereby adjusting the speed at which the electric screw conveyor conveys the material. The slower the speed, the longer the sterilization and insecticidal time of the material; the faster the speed, the longer the sterilization and insecticidal time of the material. As described above, this new type of hot air blower can output hot air through a fixed cylinder and through the air outlet of the drive shaft while conveying materials. At the same time, it generates microwaves through ten sets of microwave sterilization equipment to act on the materials, achieving continuous sterilization and insecticidal effects, thereby improving work efficiency and saving production costs.
