Description

Technical Field

[0001] This utility model relates to a combined drying oven, and more particularly to a combined drying oven with segmented heating that is applied in the field of drying oven equipment. Background Technology

[0002] The working principle of an oven is based on heat transfer. Heating elements convert electrical energy into heat, raising the internal temperature of the oven. This heat is transferred to the items to be dried through conduction, convection, and radiation, causing the moisture or other solvents in the items to evaporate, thus achieving the purpose of drying. During the drying process, the temperature control system monitors and adjusts the temperature inside the oven in real time to ensure temperature stability and accuracy, meeting the drying requirements of different items.

[0003] Chinese patent CN219120909U discloses a hot air circulating electric heating oven, the structure of which includes a base and a processing box disposed on the upper end of the base. A rectangular frame is fixedly disposed on the inner wall of the processing box. The front side of the rectangular frame is an open structure and several storage plates are disposed at intervals inside. An air inlet and an air outlet are respectively opened on the upper and lower sides of the rectangular frame. A hot air circulation mechanism is disposed on the outer side of the air inlet and the air outlet of the processing box. Two symmetrically arranged air duct groups are opened on the left and right sides of the rectangular frame. Each air duct group includes multiple air inlet ducts arranged linearly.

[0004] In terms of production efficiency, traditional drying equipment uses a relatively crude method for material turning and conveying. Its material conveying and turning mechanism lacks flexibility and cannot be dynamically adjusted according to material characteristics and drying process. It is difficult to meet the high-efficiency drying needs of small batches and multiple varieties of materials. Especially in industries such as food and chemical, where production batches are frequently switched, traditional equipment is difficult to quickly adapt to the drying requirements of different materials, which restricts the improvement of production efficiency. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the material turning and conveying methods of traditional drying equipment are relatively crude. The material conveying and turning mechanism lacks flexibility and cannot be dynamically adjusted according to the material characteristics and drying process. It is difficult to meet the high-efficiency drying needs of small batches and multiple varieties of materials. Especially in industries such as food and chemical industry, where production batches are frequently switched, traditional equipment is difficult to quickly adapt to the drying requirements of different materials, which restricts the improvement of production efficiency.

[0006] To address the aforementioned problems, this utility model provides a segmented heating combined drying oven, including a base, a drying combination chamber fixedly connected to the base, multiple drying crossbars fixedly connected to the left and right inner walls of the drying combination chamber, multiple airflow nozzles installed at the ends of two corresponding drying crossbars that are close to each other, a side limiting plate fixedly connected to the upper right side of the base, an electric conveyor belt installed at the upper left side of the side limiting plate, multiple protruding uprights fixedly connected to the outer end of the electric conveyor belt, a load-bearing side plate fixedly connected to the upper end of the protruding uprights, a motor installed at the left end of the load-bearing side plate, a tilting vertical rod connected to the output end of the motor, a vertical electric guide rail fixedly connected to the upper left side of the tilting vertical rod, a first hollow drying plate fixedly connected to the output end of the vertical electric guide rail, and a second hollow drying plate fixedly connected to the lower left side of the tilting vertical rod.

[0007] In the aforementioned segmented heating combined oven, the material in this solution passes through different temperature zones sequentially under the drive of the electric conveyor belt. The material is turned over by the motor-driven rotating vertical rod, and the vertical electric guide rail assists in lifting, so that all parts of the material can be evenly dried by the hot airflow at different temperatures.

[0008] As a further improvement of this application, two flexible curtains are fixedly connected to the upper inner wall of the drying combination chamber, and the flexible curtains are located above the electric conveyor belt.

[0009] As a further improvement to this application, the flexible curtain and the drying crossbar are separated, and multiple airflow nozzles are all externally connected to pumps.

[0010] As a further improvement of this application, the first and second perforated drying plates, which are corresponding to each other, are fitted together.

[0011] As another improvement of this application, a material discharge inclined plate is provided at the upper end of the equipment base, and a material discharge lever is fixedly connected to the right side of the front inner wall of the material discharge inclined plate.

[0012] As a further improvement to this application, the discharge lever passes through the position between the two corresponding first and second hollow drying plates, and a material storage frame is fixedly connected to the right end of the equipment base.

[0013] As a further improvement to this application, the material storage frame and the material discharge inclined panel are interconnected, and the material body is held between the first hollow drying plate and the second hollow drying plate.

[0014] In summary, this solution utilizes multiple drying crossbars with varying numbers of airflow nozzles beneath them to create drying zones with different temperature gradients within the drying chamber. Driven by an electrically conductive conveyor belt, the material sequentially passes through these temperature zones. This, combined with a motor-driven rotating vertical bar for material rotation and the lifting assistance of vertical electrically conductive rails, ensures that all parts of the material receive uniform drying from hot airflows at different temperatures. This effectively prevents over- or under-drying in certain areas, improving drying uniformity and efficiency, and guaranteeing the material achieves the desired drying effect. The discharge lever automatically sweeps the dried material onto the discharge ramp, where it finally slides into the storage frame. The entire process requires minimal manual intervention, reducing labor input, increasing production efficiency, and lowering labor costs. Attached Figure Description

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 2-7 A segmented heating combined drying oven is shown, including a base 1, a drying combination chamber 2 fixedly connected to the base 1, multiple drying crossbars 4 fixedly connected to the left and right inner walls of the drying combination chamber 2, multiple airflow nozzles 5 installed at the ends of two corresponding drying crossbars 4 that are close to each other, a side limiting plate 6 fixedly connected to the upper right side of the base 1, an electric conveyor belt 7 installed at the upper left side of the side limiting plate 6, multiple protruding uprights 9 fixedly connected to the outer end of the electric conveyor belt 7, a load-bearing side plate 8 fixedly connected to the upper end of the protruding uprights 9, a motor 11 installed at the left end of the load-bearing side plate 8, a tilting vertical rod 12 connected to the output end of the motor 11, a vertical electric guide rail 13 fixedly connected to the upper left side of the tilting vertical rod 12, a first hollow drying plate 14 fixedly connected to the output end of the vertical electric guide rail 13, and a second hollow drying plate 15 fixedly connected to the lower left side of the tilting vertical rod 12.

[0027] Figures 2-7 The upper inner wall of the drying combination chamber 2 is fixedly connected to two flexible curtains 3. The flexible curtains 3 are located above the electric conveyor belt 7. The flexible curtains 3 are separated from the drying crossbar 4. Multiple airflow nozzles 5 are externally connected to pumps. The upper and lower corresponding first hollow drying plates 14 and second hollow drying plates 15 are mutually coordinated. The upper end of the equipment base 1 is provided with a material discharge inclined plate 16. The right side of the front inner wall of the material discharge inclined plate 16 is fixedly connected to a discharge lever 17. The discharge lever 17 passes through the position between the upper and lower corresponding first hollow drying plates 14 and second hollow drying plates 15. The right end of the equipment base 1 is fixedly connected to a material storage frame 18. The material storage frame 18 and the material discharge inclined plate 16 are interconnected. The material body is clamped between the first hollow drying plates 14 and the second hollow drying plates 15.

[0028] Figures 1-7Before the equipment starts operating, the material is placed between the first perforated drying plate 14 and the second perforated drying plate 15. At this time, the motor 11 has not yet started, and the first perforated drying plate 14 and the second perforated drying plate 15 are in a separated state, which facilitates the placement of the material. After the material is placed, the motor 11 starts, and its output end drives the rotating vertical rod 12 to rotate, so that the first perforated drying plate 14 moves towards the second perforated drying plate 15 through the vertical electric guide rail 13 until the two are in contact, clamping and fixing the material. Inside the drying combination chamber 2, multiple drying horizontal rods 4 are horizontally distributed along the left and right inner walls, each... Each of the drying crossbars 4 has an airflow nozzle 5 installed at one end close to the others. These nozzles 5 are all connected to an external pump, which serves as the power source, providing a stable airflow output. Depending on the drying process requirements, the number of airflow nozzles 5 varies below different drying crossbars 4. Areas with more nozzles 5 experience a greater volume of hot airflow per unit area, resulting in a higher drying temperature; areas with fewer nozzles experience a relatively lower drying temperature. This design creates different temperature gradient drying zones within the drying chamber 2, precisely adapting to the different stages of material drying. To meet drying requirements, when the equipment is running, the electrical conveyor belt 7, constrained by the side limiting plate 6, runs smoothly along a set path. Multiple protruding uprights 9 fixed to the outer end of the electrical conveyor belt 7 move synchronously with it, thereby driving the connected load-bearing side plate 8, motor 11, tilting uprights 12, first perforated drying plate 14, and second perforated drying plate 15 to move as a whole. As the material moves through different drying zones with the components, the external control terminal precisely controls the operation of the motor 11 according to the temperature settings of each zone. The motor 11 drives the tilting uprights 12 to achieve… The overall flipping action, combined with the lifting function of the vertical electric guide rail 13, flips the material. By controlling the frequency of flipping, the material can be evenly dried by hot airflows of different temperatures, ensuring that all parts of the material achieve the ideal drying effect and avoiding local over- or under-drying. Throughout the process, the equipment base 1 provides stable support for all components. A pair of flexible curtains 3 fixed to the inner wall of the drying combination chamber 2 can reduce heat loss during the drying process and prevent foreign objects from entering the drying combination chamber 2, ensuring the smooth progress of the drying work.

[0029] Second implementation method:

[0030] Figure 2-3A segmented heating combined oven is shown. After the material completes the entire drying process, it moves to the bottom of the electric conveyor belt 7 and above the discharge inclined plate 16. At this time, the discharge lever 17 is installed on the right side of the front inner wall of the discharge inclined plate 16 and passes through the position between the first hollow drying plate 14 and the second hollow drying plate 15. As the material continues to move, the discharge lever 17 will contact the material and sweep the material down between the first hollow drying plate 14 and the second hollow drying plate 15. After being swept down, the material slides down along the inclined discharge inclined plate 16 by its own gravity and finally enters the storage frame 18, which is connected to the discharge inclined plate 16, for storage, thus realizing the function of automatic material discharge.

[0031] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
