Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, and more specifically, to a non-powered grain drying and processing equipment. Background Technology

[0002] Currently, the mainstream equipment in the grain drying and processing field is mostly traditional powered dryers. These dryers typically use electricity, coal, or natural gas as energy sources, generating high temperatures through built-in heating devices (such as electric heating elements and burners), and then using fans to blow hot air onto the grain to achieve moisture evaporation. Common traditional dryers include batch circulating dryers and continuous dryers. Their structure generally includes a heating system, a ventilation system, a grain conveying system, and a control system. They require continuous energy consumption to maintain the drying operation. For example, a medium-sized electric heating grain dryer can consume 15-30 kWh of electricity per hour. If coal heating is used, it will not only produce a large amount of waste gas that pollutes the environment, but also require regular refueling, increasing labor and cost inputs. Therefore, improvements are needed. Utility Model Content

The non-powered component includes a platform bolted to the rear side of the drying box, a tempered glass cover plate embedded in the top of the platform, a black heat-absorbing coated aluminum plate disposed inside the platform, an air layer disposed between the upper side of the black heat-absorbing coated aluminum plate and the lower side of the tempered glass cover plate inside the platform, a phase change heat storage layer disposed below the black heat-absorbing coated aluminum plate filling the interior of the platform, and a metal heat-conducting plate bolted to the interior of the platform, located below the phase change heat storage layer and extending into the interior of the drying box, the metal heat-conducting plate being located below the drying component.

[0005] As a preferred embodiment of this utility model, the drying assembly includes a drying box, and material-picking mechanisms are provided on both sides of the drying box. The material-picking mechanism includes side plates welded to both sides of the drying box. A slot is provided on the front side of the side plate, and slots penetrating the side plate are provided on both sides of the slot. The material-picking mechanism includes a support block. An insert plate extending into the slot is welded to the inner side of the support block. Movable grooves are provided on both sides of the insert plate. An inclined block extending into the slot is slidably installed inside the movable groove. A telescopic spring is elastically installed between the inner side of the movable groove and the inner side of the inclined block.

[0006] As a preferred embodiment of this utility model, the drying assembly further includes a rectangular plate bolted to the inside of the drying chamber. The rectangular plate has a sliding groove inside, and a sliding plate is slidably installed inside the sliding groove. A support plate is welded to the front end of the sliding plate, and a pull plate is welded to the front end of the support plate. Horizontal holes are evenly distributed on the surface of the support plate, and the drying box is placed above the support plate.

[0007] As a preferred technical solution of this utility model, a limiting groove is provided on the inner side of the movable groove at both ends, and a limiting block that is slidably connected inside the limiting groove is welded to the inner side of the inclined block.

[0008] As a preferred embodiment of this utility model, the inclined block is planar on one side near the support block, and the other side of the inclined block is arc-shaped.

[0009] As a preferred technical solution of this utility model, a sealing strip is provided at the connection between the top of the platform and the tempered glass cover. The sealing strip is made of high-temperature resistant silicone rubber and has a thickness of 2-3mm.

[0010] As a preferred embodiment of this utility model, the side plates are symmetrically distributed on both sides of the drying box, and the slots are opened along the vertical direction of the side plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model effectively solves the problems of high energy consumption, high pollution, and high labor costs of traditional powered dryers in the background art through a non-powered component. The top of the platform in the non-powered component is embedded with a tempered glass cover plate, and the interior is equipped with a black heat-absorbing coated aluminum plate, an air layer, a phase change heat storage layer, and a metal heat-conducting plate. During operation, it does not rely on external energy sources such as electricity, coal, or natural gas. It only receives solar radiation through the tempered glass cover plate, and the black heat-absorbing coated aluminum plate converts solar energy into heat energy. Part of the heat energy is transferred to the drying area inside the drying chamber through the air layer and the metal heat-conducting plate to achieve the temperature rise required for grain drying. The other part of the heat energy is absorbed and stored by the phase change heat storage layer, and releases heat in the evening to maintain the drying temperature. There is no energy consumption throughout the process. At the same time, there is no need to replenish fuel regularly, saving the manpower input for fuel transportation and replenishment, which greatly reduces the energy and labor costs of drying operations and meets the requirements of environmental protection and low-cost production.

[0012] 2. This utility model significantly improves the safety and convenience of grain removal through its material handling mechanism. The support block in the material handling mechanism is made of heat-insulating material and works in conjunction with components such as the insert plate, inclined plate, and telescopic spring. When placing grain, pressing the support block can drive the insert plate into the slot of the side plate, and the inclined plate is fixed by engaging with the slot, making it easy to lift the drying box stably for grain placement. When removing the dried grain, the side plate and drying box heat up as the temperature of the drying area rises during the drying process. The heat insulation properties of the support block can prevent personnel from directly contacting high-temperature components and causing burns. The fixation can be released by pressing the inclined plate, and after pulling out the insert plate, the drying box can be removed with the help of the support block. The operation is simple and safe, solving the problems of easy burns and cumbersome operation when handling grain in traditional drying equipment. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 5As shown, this utility model provides a non-powered grain drying and processing equipment, including a drying box 1, a non-powered component 5 arranged on the rear side of the drying box 1, a drying component 2 arranged inside the drying box 1, air inlets 3 arranged on both sides of the bottom end of the drying box 1, and air outlets 4 arranged on both sides of the top end of the drying box 1. The non-powered component 5 includes a platform 51 bolted to the rear side of the drying box 1, a tempered glass cover plate 52 embedded in the top of the platform 51, a black heat-absorbing coated aluminum plate 56 arranged inside the platform 51, an air layer 53 opened inside the platform 51 between the upper side of the black heat-absorbing coated aluminum plate 56 and the lower side of the tempered glass cover plate 52, a phase change heat storage layer 54 located below the black heat-absorbing coated aluminum plate 56 filled inside the platform 51, and a metal heat-conducting plate 55 bolted inside the platform 51 located below the phase change heat storage layer 54 and extending into the interior of the drying box 1. The metal heat-conducting plate 55 is located below the drying component 2.

[0017] Hold the outer side of the support block 603 in the feeding mechanism 6 with both hands. The support block 603 is made of heat-insulating material. Press the support block 603 inward, which will cause the insert plate 604 welded to the inner side of the support block 603 to move into the slot 602. When the insert plate 604 moves, it will press the inclined block 606, which will compress the telescopic spring 607 in the movable groove 605. When the insert plate 604 is fully inserted into the slot 602, the inclined block 606 will extend into the slot 610 to fix the insert plate 604. At this time, lift the support block 603 upward, thereby lifting the drying box 27. Hold the pull plate 25 in the drying assembly 2 and pull it forward, which will cause the support plate 24 welded to the pull plate 25 to drive the sliding plate 2. 3. Slide the rectangular plate 21 smoothly in the groove 22 until the support plate 24 is fully extended out of the drying box 1; place the drying box 27 above the support plate 24, and pour the grain to be dried evenly into the drying box 27 placed above the support plate 24, controlling the thickness of the grain to be laid to 5-8cm, ensuring that the grain does not exceed the edge of the drying box 27; press the inclined block 606 to disengage the inclined block 606 from the inside of the limiting groove 608, and then pull out the support block 603 to disengage the insert plate 604 from the inside of the slot 602, thereby separating the support block 603 from the drying box 27; push the pull plate 25 to make the slide plate 23 slide back into the rectangular plate 21 along the groove 22 until the support plate 24 is fully inserted into the drying box 1; During the day, solar radiation passes through the tempered glass cover 52 in the non-powered component 5 and shines onto the black heat-absorbing aluminum plate 56 inside the platform 51. The black heat-absorbing aluminum plate 56 absorbs solar energy and converts it into heat energy. Part of the heat energy is transferred to the interior of the platform 51 through the air layer 53, and the other part is evenly conducted to the drying area inside the drying chamber 1 through the metal heat-conducting plate 55, so that the temperature of the drying area gradually increases by 10-20°C compared with the external environment. During this process, the side panel 601 and the drying box 27 will rise with the temperature of the drying area. During high-temperature heating, the support block 603, due to its heat-insulating material properties, maintains a temperature consistently lower than the side plate 601 and drying box 27, preventing burns during subsequent material handling. Part of the heat generated by the black heat-absorbing aluminum plate 56 is transferred downwards to the phase change heat storage layer 54, causing the phase change material in the layer to absorb heat and transform from a solid to a liquid state, thus storing heat energy. Simultaneously, the hot air in the drying area, due to its reduced density, naturally exits from the air outlets 4 on both sides of the top of the drying box 1, while cool outside air enters the drying area from the air inlets 3 on both sides of the bottom of the drying box 1, creating continuous natural convection. The airflow passes through the transverse holes 26 on the surface of the support plate 24 and the drying box 27, making full contact with the grain and removing moisture. The moisture is then discharged from the air outlets 4 with the hot air, completing the drying process. In the evening, after solar radiation weakens, the phase change material in the phase change heat storage layer 54 transforms from a liquid to a solid state, slowly releasing the heat energy stored during the day. This heat is continuously supplied to the drying area through the metal heat-conducting plate 55, maintaining the temperature above 25°C and ensuring overnight grain drying. The operation continues uninterrupted, further reducing the moisture content of the grain. During this stage, the side plate 601 and the drying box 27 maintain a certain temperature. Pulling the pull plate 25 causes the support plate 24 to smoothly extend the drying box 27 out of the drying chamber 1. After the drying box 27 is fully extended, the support block 603 is reconnected to the side plate 601, and then the drying box 27 is removed from above the support plate 24 to avoid the surface temperature of the drying box 27 being too high and causing burns to personnel. Clean the debris on the dust filter screen of the air inlet 3 to ensure that all parts of the equipment are in place for easy use next time.

[0018] The non-powered component 5 effectively solves the problems of high energy consumption, high pollution, and high labor costs of traditional powered dryers in the background technology. The top of the platform 51 in the non-powered component 5 is embedded with a tempered glass cover plate 52, and the interior is equipped with a black heat-absorbing coated aluminum plate 56, an air layer 53, a phase change heat storage layer 54, and a metal heat-conducting plate 55. During operation, it does not rely on external energy sources such as electricity, coal, and natural gas. It only receives solar radiation through the tempered glass cover plate 52, and the black heat-absorbing coated aluminum plate 56 converts solar energy into heat energy. Part of the heat energy is transferred to the drying area inside the drying chamber 1 through the air layer 53 and the metal heat-conducting plate 55 to achieve the temperature rise required for grain drying. The other part of the heat energy is absorbed and stored by the phase change heat storage layer 54, and releases heat in the evening to maintain the drying temperature. There is no energy consumption throughout the process. At the same time, there is no need to replenish fuel regularly, saving the manpower input for fuel transportation and addition, which greatly reduces the energy and labor costs of drying operations and meets the requirements of environmental protection and low-cost production.

[0019] The drying assembly 2 includes a drying box 27. A material-picking mechanism 6 is provided on both sides of the drying box 27. The material-picking mechanism 6 includes side plates 601 welded to both sides of the drying box 27. A slot 602 is provided on the front side of the side plate 601. A slot 610 penetrating the side plate 601 is provided on both sides of the slot 602. The material-picking mechanism 6 includes a support block 603. An insert plate 604 extending into the slot 602 is welded to the inner side of the support block 603. Movable grooves 605 are provided on both sides of the insert plate 604. An inclined block 606 extending into the slot 610 is slidably installed inside the movable groove 605. A telescopic spring 607 is elastically installed between the inner side of the movable groove 605 and the inner side of the inclined block 606.

[0020] The material handling mechanism 6 significantly improves the safety and convenience of the grain removal process. The support block 603 in the material handling mechanism 6 is made of heat-insulating material and works in conjunction with components such as the insert plate 604, the inclined block 606, and the telescopic spring 607. When placing grain, pressing the support block 603 can drive the insert plate 604 to insert into the slot 602 of the side plate 601. The inclined block 606 is fixed by engaging with the slot 610, which facilitates the stable lifting of the drying box 27 for grain placement. When removing the dried grain, the side plate 601 and the drying box 27 heat up as the temperature of the drying area increases during the drying process. The heat insulation properties of the support block 603 can prevent personnel from directly contacting the high-temperature components and causing burns. The fixation can be released by pressing the inclined block 606. After pulling out the insert plate 604, the drying box 27 can be removed with the help of the support block 603. The operation is simple and safe, solving the problems of easy burns and cumbersome operation when handling grain in traditional drying equipment.

[0021] The drying assembly 2 also includes a rectangular plate 21 bolted to the inside of the drying chamber 1. The rectangular plate 21 has a groove 22 inside, and a sliding plate 23 is slidably installed inside the groove 22. A support plate 24 is welded to the front end of the sliding plate 23, and a pull plate 25 is welded to the front end of the support plate 24. Horizontal holes 26 are evenly opened on the surface of the support plate 24. The drying box 27 is placed above the support plate 24.

[0022] The rectangular plate 21 is fixed to the inside of the drying box 1 by bolts, which is stable and easy to disassemble and maintain. The sliding plate 23 slides in the sliding groove 22, and with the pull plate 25, the support plate 24 can be easily pulled in and out of the drying box 1, which is convenient for taking out and putting in the drying box 27. The horizontal holes 26 on the support plate 24 allow hot air to pass through evenly, ensuring that the grain in the drying box 27 is heated and dried evenly, improving drying efficiency and reducing the risk of localized mold growth in the grain.

[0023] Among them, the inner sides of the movable grooves 605 at both ends are provided with limiting grooves 608, and the inner side of the inclined block 606 is welded with a limiting block 609 that is slidably connected inside the limiting groove 608.

[0024] The limiting block 609 slides within the limiting groove 608, limiting the movement direction of the inclined block 606 and preventing it from shifting or falling out of the movable groove 605. This ensures that the inclined block 606 accurately engages with the slot 610 for fixation or smoothly disengages for unlocking. This guarantees stable operation of the material handling mechanism 6, prevents misalignment of the inclined block 606 from causing the drying box 27 to fail to stay in place or be obstructed during handling, and improves the reliability of the equipment.

[0025] The inclined block 606 is planar on one side near the support block 603, and arc-shaped on the other side.

[0026] The curved side of the inclined block 606 reduces the frictional resistance when it is inserted into the insert plate 604, allowing the insert plate 604 to easily squeeze the inclined block 606 to compress the telescopic spring 607 and reduce the operating force. The flat side can fit tightly against the inner wall of the slot 610 after the inclined block 606 is inserted into the slot 610, which enhances the fixing stability, prevents the insert plate 604 from loosening accidentally during use, ensures that the drying box 27 is placed stably, and improves the convenience and safety of material handling.

[0027] A sealing strip is provided at the connection between the top of the platform 51 and the tempered glass cover 52. The sealing strip is made of high-temperature resistant silicone rubber and has a thickness of 2-3mm.

[0028] The high-temperature resistant silicone rubber sealing strip can adapt to the high-temperature environment inside the non-powered component 5, avoiding heat-induced aging and failure; the 2-3mm thickness can effectively fill the connection gap between the platform 51 and the tempered glass cover 52, preventing cold air from seeping in or hot air from escaping, reducing heat loss, ensuring the heat collection and insulation effect of the non-powered component 5, improving the temperature stability of the drying area, and shortening the drying cycle.

[0029] The side plates 601 are symmetrically distributed on both sides of the drying box 27, and the slots 602 are opened along the vertical direction of the side plates 601.

[0030] The side plates 601 are symmetrically distributed on both sides of the drying box 27, which can limit the drying box 27 from both sides and prevent the drying box 27 from shifting on the support plate 24; the slot 602 is opened in the vertical direction, so that the insert plate 604 can be inserted and fixed vertically, which enhances the vertical support force after the support block 603 is connected to the side plate 601, ensures that the force is balanced when the drying box 27 is lifted, avoids the drying box 27 from tilting and causing the grain to spill, and improves the stability of picking up and putting down the grain.

[0031] Working principle and usage process of this utility model: Hold the outer side of the support block 603 in the feeding mechanism 6 with both hands. The support block 603 is made of heat-insulating material. Press the support block 603 inward, which will cause the insert plate 604 welded to the inner side of the support block 603 to move into the slot 602. When the insert plate 604 moves, it will press the inclined block 606, which will compress the telescopic spring 607 in the movable groove 605. When the insert plate 604 is fully inserted into the slot 602, the inclined block 606 will extend into the slot 610 to fix the insert plate 604. At this time, lift the support block 603 upward, thereby lifting the drying box 27. Hold the pull plate 25 in the drying assembly 2 and pull it forward, which will cause the support plate 24 welded to the pull plate 25 to drive the sliding plate 2. 3. Slide the rectangular plate 21 smoothly in the groove 22 until the support plate 24 is fully extended out of the drying box 1; place the drying box 27 above the support plate 24, and pour the grain to be dried evenly into the drying box 27 placed above the support plate 24, controlling the thickness of the grain to be laid to 5-8cm, ensuring that the grain does not exceed the edge of the drying box 27; press the inclined block 606 to disengage the inclined block 606 from the inside of the limiting groove 608, and then pull out the support block 603 to disengage the insert plate 604 from the inside of the slot 602, thereby separating the support block 603 from the drying box 27; push the pull plate 25 to make the slide plate 23 slide back into the rectangular plate 21 along the groove 22 until the support plate 24 is fully inserted into the drying box 1; During the day, solar radiation passes through the tempered glass cover 52 in the non-powered component 5 and shines onto the black heat-absorbing aluminum plate 56 inside the platform 51. The black heat-absorbing aluminum plate 56 absorbs solar energy and converts it into heat energy. Part of the heat energy is transferred to the interior of the platform 51 through the air layer 53, and the other part is evenly conducted to the drying area inside the drying chamber 1 through the metal heat-conducting plate 55, so that the temperature of the drying area gradually increases by 10-20°C compared with the external environment. During this process, the side panel 601 and the drying box 27 will rise with the temperature of the drying area. During high-temperature heating, the support block 603, due to its heat-insulating material properties, maintains a temperature consistently lower than the side plate 601 and drying box 27, preventing burns during subsequent material handling. Part of the heat generated by the black heat-absorbing aluminum plate 56 is transferred downwards to the phase change heat storage layer 54, causing the phase change material in the layer to absorb heat and transform from a solid to a liquid state, thus storing heat energy. Simultaneously, the hot air in the drying area, due to its reduced density, naturally exits from the air outlets 4 on both sides of the top of the drying box 1, while cool outside air enters the drying area from the air inlets 3 on both sides of the bottom of the drying box 1, creating continuous natural convection.

The operation continues uninterrupted, further reducing the moisture content of the grain. During this stage, the side plate 601 and the drying box 27 maintain a certain temperature. Pulling the pull plate 25 causes the support plate 24 to smoothly extend the drying box 27 out of the drying chamber 1.
