Description

Technical Field

[0001] This utility model relates to the field of grain drying equipment, and in particular to a grain storage drying device. Background Technology

[0002] Grain storage drying equipment is a device used to reduce the moisture content of grains to meet safe storage standards. Before processing grains, grain processing enterprises need to dry them to a suitable moisture content to facilitate subsequent processing.

[0003] During the drying process, grain is in a relatively static state, making it difficult for hot air to penetrate the grain layer evenly. Grain near the heating source or vents may be over-dried, while grain further away may be under-dried. Uneven drying affects the quality of the grain. Over-dried areas may become scorched or discolored, affecting taste and nutritional value; under-dried areas are prone to mold and sprouting during storage, reducing storage stability. Inconsistent moisture content across the batch of grain prolongs drying time and hinders further heat exchange between hot air and grain, slowing down the drying process. During drying, hot air may concentrate in certain areas, causing excessively high temperatures and scorching of the grain; while other areas may remain too cool due to insufficient hot air, resulting in incomplete drying. Uneven drying can also occur, with some hot air flowing erratically and being expelled from the drying unit before fully drying, leading to wasted heat, increased energy consumption, higher drying costs, accelerated equipment aging and damage, and a reduced lifespan. Utility Model Content

[0004] The main purpose of this utility model is to provide a drying device for grain storage, which can effectively solve the problems of reduced grain storage stability, inconsistent moisture content of the whole batch of grain, correspondingly extended drying time, which to some extent hinders further heat exchange between hot air and grain, slows down the drying speed, and causes heat waste, increases energy consumption, increases drying costs, accelerates equipment aging and damage, and reduces the service life of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grain storage drying device, comprising a box body, an outer cylinder arranged inside the box body, a retaining ring fixedly connected to the left side of the outer cylinder, three upper flow plates fixedly connected to the inner top wall of the outer cylinder, four lower flow plates fixedly connected to the inner bottom wall of the outer cylinder, an inner cylinder arranged inside the outer cylinder, the left outer end of the inner cylinder rotatably connected to the inside of the retaining ring, the outer side of the inner cylinder rotatably connected to the inside of the three upper flow plates and the four lower flow plates, a semi-circular plate fixedly connected to the left side of the inner cylinder, a feed hopper fixedly connected to the left end of the outer cylinder, the interior of the feed hopper having the same configuration as the left side of the inner cylinder, a spiral blade fixedly connected to the inside of the inner cylinder, a retainer fixedly connected to the top right side of the box body, and a motor arranged on the right side wall of the retainer.

[0006] Furthermore, a rotating rod is fixedly connected to the output end of the motor, and the rotation of the rotating rod is connected inside the fixture. A collection box is provided on the outer right end of the outer cylinder, and a sleeve is fixedly connected to the outer left end of the rotating rod through the inside of the collection box.

[0007] Furthermore, the left side wall of the sleeve is fixedly connected to the right side wall of the inner cylinder, the groove on the right side wall of the inner cylinder is connected to the collection box, the bottom of the collection box is connected through a discharge pipe, and the outer side of the discharge pipe is connected through to the bottom wall of the box.

[0008] Furthermore, a control panel is fixedly connected to the right side of the front wall of the housing, support legs are fixedly connected to the bottom wall of the housing, an exhaust pipe is connected through the top right side of the outer cylinder, and an air inlet plate is fixedly connected to the bottom left end of the outer cylinder.

[0009] Furthermore, a device box is fixedly connected to the right side wall of the box body, and heating chambers are provided on both the front and rear sides of the box body. The two heating chambers are located on the bottom wall of the outer cylinder, and a power supply is fixedly connected inside the device box.

[0010] Furthermore, the output terminal of the power supply is connected to a resistor, a heat-conducting plate is fixedly connected to the front side of the resistor, and a triplet is fixedly connected to the top of the heat-conducting plate.

[0011] Furthermore, the top and bottom ends of the three-tube joint are connected to copper tubes, and the left ends of the two copper tubes are fixedly connected to heating tubes, which are located inside the two heating chambers.

[0012] Furthermore, baffles are fixedly connected to the outer walls of the two heating chambers, and partitions are fixedly connected to the inner left walls of the two baffles. Both partitions are located on the front and rear sides of the bottom wall of the air inlet plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model, through its outer cylinder, inner cylinder, feed hopper, spiral blades, motor, rotating rod, collection box, and discharge pipe, solves the problems that reduce the storage stability of grain, cause inconsistent moisture content throughout the batch of grain, extend drying time, and hinder further heat exchange between hot air and grain, thus slowing down the drying speed. The rotating rod drives the sleeve to rotate, which in turn causes the inner cylinder to rotate. The spiral blades inside the inner cylinder push the grain from left to right as the inner cylinder rotates. During this pushing process, the grain continuously tumbles inside the inner cylinder, making full contact with the inner wall, thereby effectively improving the uniform heating effect, ensuring consistent moisture content throughout the batch of grain, improving drying quality, shortening drying time, and increasing drying efficiency.

The heat generated by the heating elements raises the temperature inside the heating chamber. The baffles and partition plates on the outer side of the heating chamber guide and separate airflow. Outside air enters through the air inlet plate, is heated in the heating chamber, and then passes through the guide channels formed by the upper and lower flow plates inside the outer cylinder, ensuring full contact with the inner cylinder and heating and drying the grain inside. Moisture generated during the drying process is discharged through the exhaust pipe, effectively increasing the contact area and time between the grain and hot air, accelerating moisture evaporation, improving drying efficiency, and ensuring uniform drying.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 - Figure 6 As shown: A grain storage drying device includes a housing 1, with an outer cylinder 2 inside the housing 1. The outer cylinder 2 provides external support for the heat and the inner cylinder 6. A retaining ring 3 is fixedly connected to the inside of the left side of the outer cylinder 2. Three upper flow plates 4 are fixedly connected to the top wall of the outer cylinder 2, and four lower flow plates 5 are fixedly connected to the bottom wall of the outer cylinder 2. The three upper flow plates 4 fixed to the top wall of the outer cylinder 2 and the four lower flow plates 5 fixed to the bottom wall of the outer cylinder 2 guide the heat entering the outer cylinder 2, causing the heat to move in an S-shaped path inside the outer cylinder 2 to fully cover the outer side of the inner cylinder 6 and provide heat to the inner wall of the inner cylinder 6.

[0031] An inner cylinder 6 is housed inside the outer cylinder 2. The outer left end of the inner cylinder 6 is rotatably connected to the inside of a retaining ring 3. This connection provides support for the left end of the inner cylinder 6 and ensures stable rotation. The outer side of the inner cylinder 6 is rotatably connected to the inside of three upper flow plates 4 and four lower flow plates 5. This connection also supports the inner cylinder 6 and, through heat conduction and convection, transfers heat to the inner cylinder 6, thereby heating and drying the grain inside. The moisture in the grain evaporates upon heating, forming humid air. This humid air is discharged through an exhaust pipe 18 on the top right side of the outer cylinder 2, ensuring a dry environment inside and maintaining drying efficiency.

[0032] A semi-circular plate 7 is fixedly connected to the left side of the inner cylinder 6. This semi-circular plate 7 prevents grain from being discharged from the left end of the inner cylinder 6 during rotation. A feed hopper 8 is fixedly connected to the left end of the outer cylinder 2. The interior of the feed hopper 8 is configured similarly to the left side of the inner cylinder 6. By fixing the feed hopper 8 to the upper left of the outer cylinder 2 and aligning it with the left side of the inner cylinder 6, the grain is ensured to accurately enter the inner cylinder 6 after being fed into the feed hopper 8. A spiral blade 9 is fixedly connected inside the inner cylinder 6. A retainer 11 is fixedly connected to the top right side of the housing 1. A motor 10 is installed on the right side wall of the retainer 11. When the inner cylinder 6 is driven, the spiral blade 9 inside rotates synchronously with the inner cylinder 6. Under the push of the spiral surface of the spiral blade 9, the grain moves from the left side to the right side of the inner cylinder 6.

[0033] In addition, during this process, the grain not only undergoes axial displacement, but also continuously tumbles and stirs inside the inner cylinder 6 under the action of the spiral blades 9. The tumbling motion allows the grain to fully contact the inner wall of the inner cylinder 6, so that all parts of the grain can be heated evenly.

[0034] like Figure 1 - Figure 7 As shown, a rotating rod 12 is fixedly connected to the output end of the motor 10. The rotating rod 12 is rotatably connected inside the fixture 11. A collection box 14 is provided on the outer right side of the outer cylinder 2. A sleeve 13 is fixedly connected to the outer left side of the rotating rod 12, penetrating the interior of the collection box 14. The left side wall of the sleeve 13 is fixedly connected to the right side wall of the inner cylinder 6. After starting the motor 10, the rotating rod 12 at the output end of the motor 10 begins to rotate at high speed. The rotating rod 12 passes through the interior of the fixture 11, and the sleeve 13 on its outer left side is firmly connected to the right side wall of the inner cylinder 6, thereby driving the inner cylinder 6 to rotate around its own axis.

[0035] The right side wall of the inner cylinder 6 has a groove that communicates with the collecting box 14. A discharge pipe 15 is connected through the bottom of the collecting box 14, and the outer side of the discharge pipe 15 is connected through the bottom wall of the box body 1. When the grain is pushed to the right by the spiral blades 9 inside the inner cylinder 6, the grain can smoothly enter the collecting box 14 from the inner cylinder 6 due to the precise matching of the groove on the right side wall of the inner cylinder 6 with the structure of the collecting box 14. The collecting box 14 serves as a temporary storage for the dried grain, which is then discharged from the box body 1 through the discharge pipe 15 connected through the bottom.

[0036] like Figure 1 - Figure 8 As shown, a control panel 16 is fixedly connected to the right side of the front wall of the housing 1, through which the entire device is controlled. Support legs 17 are fixedly connected to the bottom wall of the housing 1, providing support for the bottom of the entire device.

[0037] An exhaust pipe 18 is connected through the top right side of the outer cylinder 2, and an air inlet plate 19 is fixedly connected to the bottom left end of the outer cylinder 2. The generated heat is transported to the inside of the outer cylinder 2 and the gaps on the outside of the inner cylinder 6 through the air inlet plate 19 at the bottom of the outer cylinder 2. The heat comes into contact with the inner cylinder 6 through the arrangement of the upper flow plate 4 and the lower flow plate 5, and the heat is finally discharged through the exhaust pipe 18 at the top of the outer cylinder 2.

[0038] A device box 20 is fixedly connected to the right side wall of the housing 1. The device box 20 is used to protect the internal devices. Heating chambers 21 are provided on both the front and rear sides of the interior of the housing 1. The heat generated by the heating chambers 21 is initially stored. The two heating chambers 21 are located on the bottom wall of the outer cylinder 2. A power supply 22 is fixedly connected inside the device box 20.

[0039] A resistor 23 is connected to the output terminal of the power supply 22. A heat-conducting plate 24 is fixedly connected to the front of the resistor 23. The power supply 22 inside the device box 20 serves as the energy supply core, supplying power to the resistor 23 through the circuit. According to Joule's law, when current passes through the resistor 23, electrical energy is converted into heat energy, and the resistor 23 heats up rapidly. The heat generated by the resistor 23 is transferred to the heat-conducting plate 24 on the front side by thermal conduction. The heat-conducting plate 24 has good thermal conductivity and can quickly absorb and evenly distribute heat.

[0040] A triplet 25 is fixedly connected to the top of the heat-conducting plate 24. Both ends of the triplet 25 are connected to copper pipes 26. Heating elements 27 are fixedly connected to the left ends of both copper pipes 26. The two heating elements 27 are located inside the two heating chambers 21. Heat is transferred from the heat-conducting plate 24 to the triplet 25, which further distributes the heat. The heat is then transported to the heating elements 27 located in the front and rear heating chambers 21 inside the housing 1 via the copper pipes 26. After absorbing heat, the heating elements 27 rapidly heat the surrounding air, causing the temperature inside the heating chamber 21 to rise rapidly, forming a stable high-temperature heat source.

[0041] Two heating chambers 21 are fixedly connected to the outer walls of the two heating chambers 21. Two partition plates 29 are fixedly connected to the inner left walls of the two partition plates 28. The two partition plates 29 are set on the front and rear sides of the bottom wall of the air inlet plate 19. The heat inside the heating chamber 21 is guided by the baffles 28, so that the heat is discharged through the partition plates 29 on the left side of the baffles 28. In addition, the heat is set on the top of the two partition plates 29 through the air inlet plate 19, so that the heat enters the interior of the outer cylinder 2 through the air inlet plate 19, so as to contact the inner cylinder 6 and dry the grain inside the inner cylinder 6.

[0042] It should be noted that this utility model is a drying device for grain storage. First, the motor 10, power supply 22, and control panel 16 are connected to an external power source to supply power to the device.

[0043] First, the grain enters the inner cylinder 6 through the feed hopper 8. Since the internal structure of the feed hopper 8 is identical to that of the left side of the inner cylinder 6, the grain flows in smoothly. After the motor 10 starts, it drives the sleeve 13 to rotate via the rotating rod 12, thereby causing the inner cylinder 6 to rotate. As the inner cylinder 6 rotates, the spiral blades 9 inside push the grain from the left side to the right. During this pushing process, the grain continuously tumbles inside the inner cylinder 6, making full contact with the inner wall of the inner cylinder 6.

[0044] At this time, the power supply 22 inside the device box 20 supplies power to the resistor 23, which heats up. The heat is transferred to the triple tube 25 through the heat-conducting plate 24, and then transported to the heating tube 27 set in the heating chamber 21 through the copper tube 26. The heat generated by the heating tube 27 raises the temperature inside the heating chamber 21. The baffle 28 and partition 29 on the outside of the heating chamber 21 guide and separate the airflow.

[0045] Outside air enters through the air inlet plate 19, is heated by the heating chamber 21, and then passes through the guide channel formed by the upper flow plate 4 and the lower flow plate 5 inside the outer cylinder 2, making full contact with the inner cylinder 6 to heat and dry the inner cylinder 6 and the grain inside. The moisture generated during the drying process is discharged through the exhaust pipe 18.

[0046] When the grain is pushed to the right side inside the inner cylinder 6, since the groove on the right side wall of the inner cylinder 6 has the same structure as the collection box 14, the grain smoothly enters the collection box 14 and is discharged from the box 1 through the discharge pipe 15, thus completing the drying operation.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
