Description

Technical Field

[0001] This utility model relates to the technical field of gas-fired drying equipment, specifically to a gas-fired drying equipment for kernels. Background Technology

[0002] A pumpkin seed dryer is a device used to dry pumpkin seeds to achieve the ideal degree of dryness and quality. It heats the air through heating elements, and the hot air circulates in the drying chamber, making full contact with the pumpkin seeds and removing moisture. For example, a hot air circulating oven uses a circulating fan to keep the hot air circulating in the chamber, achieving uniform heating and drying.

[0003] Existing gas-fired drying equipment typically dries pumpkin seeds by circulating hot air. The circulating hot air causes the damp pumpkin seeds to evaporate water vapor, which then enters the circulating hot air and easily comes into contact with the pumpkin seeds during circulation, causing the dried pumpkin seeds to be affected by the water vapor. Utility Model Content

[0004] To address this issue, this utility model provides a seed kernel gas drying device. By combining absorbent cotton with a water-squeezing component, it solves the problem that the hot air in circulation carries evaporated water vapor, which easily comes into contact with the pumpkin seeds during transport, causing the dried pumpkin seeds to be affected by water vapor interference.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas-fired drying equipment for kernels, comprising a gas-fired drying chamber body, a feeding hopper fixedly provided on one side of the gas-fired drying chamber body, a filter-type conveyor belt device inserted inside the gas-fired drying chamber body, a feeding chamber on the right side of the gas-fired drying chamber body, a cooling chamber on the left side of the gas-fired drying chamber body, multiple drying chambers inside the gas-fired drying chamber body, ventilation openings on one side of each of the multiple drying chambers, drainage slopes at the bottom of two of the drying chambers, drainage holes at the bottom of each of the two drainage slopes, two metal ventilation meshes fixedly provided inside each of the multiple drying chambers, a gas-fired heating device fixedly connected inside each of the multiple drying chambers, absorbent cotton fixedly provided inside two of the drying chambers, and a flow fan fixedly provided at the bottom of the other two drying chambers, with a water-squeezing component at the bottom of each of the two absorbent cottons.

[0006] Preferably, the plurality of drying chambers and the ventilation openings form an air duct structure.

[0007] Preferably, an exhaust device is fixedly installed at the bottom of the cooling chamber, and a cooling fan is fixedly installed at the top of the cooling chamber.

[0008] Preferably, both metal ventilation meshes are fixedly installed inside the drying chamber, and the two metal ventilation meshes are respectively installed on the upper and lower sides of the filter conveyor belt device.

[0009] Preferably, the absorbent cotton is fixedly installed inside the drying chamber, and the top of the absorbent cotton is fixedly connected to the adjacent metal ventilation mesh.

[0010] Preferably, the dewatering assembly includes an electric push rod, which is fixedly mounted on the bottom of the gas-fired drying chamber. A push rod is fixedly connected to the output end of the electric push rod. The top of the push rod extends into the drying chamber and is slidably connected to the bottom of the drying chamber. A top plate is fixedly mounted on the top of the push rod. A dewatering plate is fixedly mounted on the top of the top plate. A sealing plate is fitted over the top plate and is fixedly connected to the inner wall of the drying chamber.

[0011] Preferably, the feeding chamber, cooling chamber, and multiple drying chambers are all connected to a door on one side.

[0012] Preferably, the bottom of the gas drying box body is fixedly provided with two support feet.

[0013] The present invention has the following advantages:

[0014] 1. Through the air duct structure composed of multiple drying chambers and circulating ventilation openings, hot air circulates along the "up-down-up-down" path to achieve three-dimensional and uniform drying of pumpkin seeds, avoiding insufficient or excessive drying in some areas. The metal ventilation mesh on the upper and lower sides of the drying chamber can block the direct impact of hot air flow on pumpkin seeds, prevent the material from being blown away from the conveyor belt, ensure a smooth conveying process, and guide hot air to pass evenly through the material layer, improving the uniformity of drying.

[0015] 2. The absorbent cotton can absorb moisture from the circulating hot air, preventing moisture from flowing back into the dried pumpkin seeds, avoiding the "dampness" problem, and ensuring a stable moisture content in the final product. The dewatering assembly uses an electric push rod to drive the dewatering plate to squeeze the absorbent cotton, discharging the water through the drain slope and drain holes, achieving centralized treatment of moisture and preventing water accumulation inside the equipment from affecting drying efficiency.

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See attached document Figure 1 -Appendix Figure 7This utility model provides a gas-fired drying equipment for kernels, including a gas-fired drying chamber body 1, a feeding hopper 3 fixedly provided on one side of the gas-fired drying chamber body 1, a filter conveyor belt device 4 inserted inside the gas-fired drying chamber body 1, a feeding chamber 5 on the right side of the gas-fired drying chamber body 1, a cooling chamber 7 on the left side of the gas-fired drying chamber body 1, multiple drying chambers 6 inside the gas-fired drying chamber body 1, ventilation openings 8 on one side of each of the multiple drying chambers 6, drainage slopes 9 at the bottom of two of the drying chambers 6, drainage holes 10 at the bottom of each of the two drainage slopes 9, two metal ventilation meshes 11 fixedly provided inside each of the multiple drying chambers 6, a gas heating device 14 fixedly connected inside each of the multiple drying chambers 6, absorbent cotton 12 fixedly provided inside two of the drying chambers 6, and a flow fan 15 fixedly provided at the bottom of the other two drying chambers 6, with a water squeezing component 16 at the bottom of each of the two absorbent cotton 12.

[0028] In this embodiment, in order to achieve the purpose of filtering and absorbing water vapor in the circulating hot air, the airflow fan 15 blows the air to make the air circulate and pass through the gas heating device 14, thereby heating the air into hot air. Through the cooperation of four drying chambers 6 and four airflow vents 8, the hot air circulates from right to left in the drying chamber 6 in the direction of up-down-up-down, thereby fully drying the pumpkin seeds conveyed by the filter conveyor belt device 4. When the damp pumpkin seeds are dried by the hot air, water vapor will evaporate. The evaporated water vapor will participate in the circulating hot air. When the hot air circulates, it will pass through the water-absorbing cotton 12, which filters and absorbs the water vapor in the hot air, and finally the dry hot air is discharged into the lower part of the cooling chamber 7.

[0029] To achieve the purpose of forming an airflow ventilation duct, this device adopts the following technical solution: multiple drying chambers 6 and circulation vents 8 form an air duct structure; an exhaust device 13 is fixedly installed at the bottom of the cooling chamber 7; a cooling fan 17 is fixedly installed at the top of the cooling chamber 7; and two support feet 2 are fixedly installed at the bottom of the gas drying box body 1. Through the cooperation of the four drying chambers 6 and the four circulation vents 8, the hot air flows from right to left in the drying chamber 6 in the direction of up-down-up-down, thereby fully drying the pumpkin seeds conveyed by the filter conveyor belt device 4. The cooling fan 17 in the cooling chamber 7 works to introduce air from outside the gas drying box body 1. Since there is no heating device in the cooling chamber 7, the air blowing from top to bottom in the cooling chamber 7 is cold air, which cools the dried pumpkin seeds on the filter conveyor belt device 4. Finally, it will be discharged from the gas drying box body 1 through the exhaust device 13 along with the hot air discharged from the bottom of the cooling chamber 7 through the circulation vents 8, forming a pumpkin seed drying and cooling process.

[0030] To prevent the circulating hot air from blowing away the pumpkin seeds conveyed on the filter conveyor belt device 4, the device adopts the following technical solution: two metal ventilation meshes 11 are fixedly installed inside the drying chamber 6, and the two metal ventilation meshes 11 are respectively installed on the upper and lower sides of the filter conveyor belt device 4. When the hot air blows the pumpkin seeds on the filter conveyor belt device 4 from top to bottom to dry them, the air pressure presses the pumpkin seeds onto the filter conveyor belt device 4, so that the pumpkin seeds will not detach from the filter conveyor belt device 4. When the hot air blows the pumpkin seeds on the filter conveyor belt device 4 from bottom to top to dry them, the metal ventilation meshes 11 block the flow of the pumpkin seeds, preventing them from being blown into other areas of the drying chamber 6, so that the pumpkin seeds are always within the conveying area of ​​the filter conveyor belt device 4.

[0031] To achieve the purpose of absorbing moisture from circulating hot air and facilitating its discharge, this device employs the following technical solution: Absorbent cotton 12 is fixedly installed inside the drying chamber 6, with its top fixedly connected to the adjacent metal ventilation mesh 11. The dewatering assembly 16 includes an electric push rod 161, which is fixedly installed at the bottom of the gas-fired drying chamber body 1. A push rod 162 is fixedly connected to the output end of the electric push rod 161. The top of the push rod 162 extends into the drying chamber 6 and slides through the bottom of the drying chamber 6. A top plate 163 is fixedly installed on the top of the push rod 162, and a dewatering plate 164 is fixedly installed on the top of the top plate 163. A sealing plate 165 is fitted over the top plate 163 and fixedly connected to the inner wall of the drying chamber 6. The absorbent cotton 12 filters and absorbs moisture from the hot air. When it is necessary to squeeze out the water vapor absorbed by the absorbent cotton 12, the electric push rod 161 is activated. The electric push rod 161 causes the push rod 162 to extend and move upward. The movement of the push rod 162 causes the top plate 163 to separate from the sealing plate 165. At the same time, the top plate 163 causes the water squeezing plate 164 to move upward and contact the absorbent cotton 12, squeezing the absorbent cotton 12 and squeezing out the water vapor absorbed in the absorbent cotton 12. The water vapor drips into the drainage slope 9 through the gap between the top plate 163 and the sealing plate 165, and finally exits outside the gas drying box body 1 through the drainage hole 10, achieving the purpose of centralized discharge of absorbed water vapor. After the water squeezing is completed, the water squeezing component 16 is reset, so that the top plate 163 is retracted into the sealing plate 165, sealing the bottom of the drying chamber 6, so that the air in the drying chamber 6 can only circulate through the ventilation port 8.

[0032] In order to facilitate subsequent observation or maintenance of the internal conditions of the feeding chamber 5, drying chamber 6, and cooling chamber 7, the device adopts the following technical solution: the feeding chamber 5, cooling chamber 7, and multiple drying chambers 6 are all connected to a door 18 on one side. By controlling the opening and closing of the door 18, it is convenient to observe or maintain the internal conditions of the feeding chamber 5, drying chamber 6, and cooling chamber 7.

[0033] The usage process of this utility model is as follows: When using this utility model, connect an external power source. When drying pumpkin seeds is required, feed the pumpkin seeds into the feeding hopper 3. The pumpkin seeds enter the feeding chamber 5 through the feeding hopper 3 and fall onto the filter conveyor belt device 4. Start the filter conveyor belt device 4 to transport the pumpkin seeds, so that the pumpkin seeds enter the drying chamber 6 from the feeding chamber 5. Start the gas heating device 14 and the airflow fan 15. The gas heating device 14 provides heat through gas combustion, and the airflow fan 15 introduces air from outside the gas drying chamber 1 and blows it into the drying chamber 6. The airflow fan 15 blows air through the gas heating device 14, heating it into hot air. Through the coordination of four drying chambers 6 and four air vents 8, the hot air flows from right to left within the drying chambers 6 in an up-down-up-down direction, thoroughly drying the pumpkin seeds conveyed by the filter conveyor belt 4. When the damp pumpkin seeds are dried by the hot air, they evaporate moisture, which then enters the flowing hot air. The hot air then passes through the absorbent cotton 12, which filters and absorbs the moisture in the hot air. The process involves drawing air from outside the gas-fired drying chamber 1, which is then exhausted into the lower part of the cooling chamber 7. Simultaneously, the cooling fan 17 operates within the cooling chamber 7, drawing air from the outside of the chamber. Since there is no heating device in the cooling chamber 7, the air blowing downwards is cold air, cooling the dried pumpkin seeds on the filter conveyor belt 4. This cold air, along with the hot air exhausted from the lower part of the cooling chamber 7 through the ventilation vent 8, is then discharged from the gas-fired drying chamber 1 through the exhaust device 13, completing the pumpkin seed drying and cooling process. When it is necessary to dry the absorbent cotton 12... When the absorbed water vapor is squeezed out, the electric push rod 161 is activated, which causes the push rod 162 to extend and move upward. The movement of the push rod 162 causes the top plate 163 to separate from the sealing plate 165. At the same time, the top plate 163 causes the water squeezing plate 164 to move upward and come into contact with the absorbent cotton 12, squeezing the absorbent cotton 12 and squeezing out the water vapor absorbed in the absorbent cotton 12. The water vapor drips into the drainage slope 9 through the gap between the top plate 163 and the sealing plate 165, and finally exits to the outside of the gas drying box body 1 through the drainage hole 10, so as to achieve the purpose of centralized discharge of absorbed water vapor.

[0034] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
