Description

Technical Field

[0001] This utility model belongs to the field of grain processing technology, and in particular relates to a hot air furnace for grain drying. Background Technology

[0002] The main purpose of grain drying is to rapidly reduce the moisture content of grain after harvest to meet safe storage standards, prevent mold, pests, and sprouting, and ensure stable grain quality. Drying effectively extends the shelf life of grain, reduces losses caused by moisture, and ensures the safety and quality of grain during transportation and storage. A grain hot air furnace is a highly efficient heating device specifically designed for grain drying. It generates heat by burning biomass, coal, or using electricity to heat the air and evaporate the moisture in the grain, ensuring that the grain reaches safe humidity standards before storage. It not only improves grain drying efficiency but also reduces losses due to mold caused by moisture, which is crucial for ensuring both grain quality and quantity.

[0003] The problems with existing technology are that the filter plates of existing equipment are often complicated and time-consuming to disassemble, resulting in a lot of time and manpower required for maintenance. In addition, the exhaust pipe of existing equipment lacks effective shielding, which can easily cause dust to enter the equipment from the exhaust pipe, increasing the risk of pollution and failure. Utility Model Content

A connecting groove 5 is opened on the rear side of the air inlet pipe 3, and a filter plate 6 is slidably connected inside the connecting groove 5.

[0023] refer to Figure 2 and Figure 4 Fixing blocks 7 are fixedly connected to both the upper and lower sides of the rear surface of the connecting groove 5. The positions of the fixing blocks 7 correspond to the positions of the connecting groove 5. Each fixing block 7 has a receiving groove 8 inside. A spring 9 is fixedly connected to the right side of each receiving groove 8. A connecting plate 10 is fixedly connected to the other end of each spring 9. A limiting rod 11 is fixedly connected to the left side of each connecting plate 10. Through holes 12 are opened on both the upper and lower sides of the rear surface of the filter plate 6. The left end of the limiting rod 11 penetrates through and extends out of the surface of the fixing block 7. The limiting rod 11 is used in conjunction with the through hole 12.

[0024] By adopting the above solution, the filter plate 6 can be easily disassembled and cleaned by setting the limiting rod 11 and the through hole 12, while ensuring its stability and reliability during operation, thereby improving the maintenance convenience and operating efficiency of the equipment.

[0025] refer to Figure 2 and Figure 4 A pull rod 13 is fixedly connected to the right side of the connecting plate 10. The right end of the pull rod 13 passes through and extends out of the surface of the fixing block 7. A movable plate 14 is placed on the rear side of the air intake pipe 3. The front side of the movable plate 14 is slidably connected to the rear side of the air intake pipe 3. The right end of the pull rod 13 is fixedly connected to the left side of the movable plate 14.

[0026] By adopting the above solution, by setting the pull rod 13 and the movable plate 14, the user can easily pull the movable plate 14 to control the locking and releasing of the filter plate 6, which greatly simplifies the disassembly and installation process of the filter plate 6.

[0027] refer to Figure 4 Two stabilizing rods 15 are provided inside the receiving groove 8. The left and right sides of the stabilizing rods 15 are fixedly connected to the surface of the receiving groove 8. The side of the stabilizing rods 15 near the connecting plate 10 passes through and extends out of the surface of the connecting plate 10. The connecting plate 10 is slidably connected to the surface of the stabilizing rods 15.

[0028] By adopting the above solution, by setting the stabilizing bar 15, it can be ensured that the connecting plate 10 remains stable and directionally accurate during movement, avoiding deviation caused by vibration or external force.

[0029] refer to Figure 3 A top cover 16 is placed on both the front and rear sides of the top of the exhaust pipe 2. The left and right sides of the top cover 16 are rotatably connected to the top of the exhaust pipe 2. Gears 17 are fixedly connected to the opposite sides of the right surface of the top cover 16. A slide groove 18 is opened on the right side of the exhaust pipe 2. Two racks 19 are placed on the right side of the exhaust pipe 2. The racks 19 are slidably connected to the inside of the slide groove 18. The racks 19 are meshed with the gears 17.

[0030] By adopting the above solution, by setting the top cover 16, it is possible to effectively prevent dust and other impurities from entering the equipment from the top of the exhaust pipe 2 when the equipment is not in use.

[0031] refer to Figure 3 A dual-head motor 20 is fixedly connected to the right side of the exhaust pipe 2. Screws 21 are fixedly connected to the output ends of the front and rear sides of the dual-head motor 20. The threads of the front screw 21 and the rear screw 21 are opposite. The other end of the screw 21 is rotatably connected to the surface of the exhaust pipe 2. The surface of the screw 21 is threadedly connected to the connecting rod 22. The top of the connecting rod 22 is fixedly connected to the bottom of the rack 19.

[0032] By adopting the above solution, the top cover 16 can be automatically opened and closed by setting up a dual-head motor 20 and a screw 21, ensuring that the top cover 16 can be tightly closed when the equipment is not in use, effectively preventing dust and other impurities from entering the equipment, keeping the equipment clean and extending its service life.

[0033] refer to Figure 3 Two stabilizing grooves 23 are provided on the right side of the exhaust pipe 2, and the left side of the connecting rod 22 is slidably connected to the inside of the stabilizing groove 23.

[0034] By adopting the above solution, by setting the stabilizing groove 23, it is possible to ensure the smooth and precise guidance of the connecting rod 22 during movement, making the opening and closing of the top cover 16 smoother and more reliable, and preventing jamming or deviation during operation.

[0035] The working principle of this utility model:

[0036] In operation, first, start the dual-head motor 20. The dual-head motor 20 drives the two screws 21 to rotate. The screws 21 drive the connecting rods 22 to move along the stabilizing groove 23. Since the threads of the two screws 21 turn in opposite directions, the connecting rods 22 move in opposite directions. Then, the connecting rods 22 drive the rack 19 to move. The rack 19 drives the gear 17 to rotate. The gear 17 drives the top cover 16 to rotate. After the top covers 16 on both sides are opened, turn off the dual-head motor 20. Then, start the blower 4 and the hot air furnace body 1. The blower 4 will blow air into the interior of the hot air furnace body 1. The air will first be filtered by the filter plate 6, and then... After passing through the hot air furnace body 1, the ash is finally discharged from the exhaust pipe 2. After the equipment has been used for a period of time, the filter plate 6 needs to be cleaned or replaced. When disassembling the filter plate 6, first pull the moving plate 14 to the right. The moving plate 14 drives the pull rods 13 on both sides to move. The pull rods 13 drive the connecting plate 10 and the limiting rod 11 to move to the right. When the limiting rod 11 moves out of the through hole 12, the filter plate 6 can be taken out of the connecting groove 5. When installing the filter plate 6, first insert the filter plate 6 into the connecting groove 5, and then insert the limiting rods 11 on both sides into the through hole 12 to fix the filter plate 6 and prevent it from moving.

[0037] In summary, this hot air furnace for grain drying, through the coordinated use of the following components—hot air furnace body 1, exhaust pipe 2, air inlet pipe 3, fan 4, connecting groove 5, filter plate 6, fixing block 7, receiving groove 8, spring 9, connecting plate 10, limit rod 11, through hole 12, pull rod 13, moving plate 14, stabilizing rod 15, top cover 16, gear 17, slide 18, rack 19, double-headed motor 20, screw 21, connecting rod 22, and stabilizing groove 23—solves the problems of existing equipment where filter plate disassembly is often complex and time-consuming, leading to significant time and manpower expenditure for maintenance. Furthermore, the existing equipment's exhaust pipe lacks effective shielding, easily allowing dust to enter the equipment, increasing the risk of contamination and malfunction.
