Description

Technical Field

[0001] The present application relates to the technical field of drying ovens, and in particular to a constant temperature drying oven. Background Art

[0002] A drying oven, also known as an "oven", blows out hot air through a circulating fan to ensure temperature balance inside the oven. It is a commonly used instrument and equipment, mainly used to dry samples. With the widespread application of traditional Chinese medicine and the increasing demand for modern production, a drying oven is needed to dry Chinese herbal medicines for better preservation.

[0003] A constant temperature drying oven disclosed in an existing Chinese patent application (authorization announcement number: CN219889994U) comprises a drying oven, wherein the inner wall of the drying oven is symmetrically provided with holders, and racks are movably connected between the holders. A heating lamp is provided on the inner wall of the drying oven between adjacent racks. A water receiving trough is provided at the bottom of the drying oven cavity, a fixed net is provided at the upper end of the water receiving trough, and a water receiving tray is provided at the bottom of the water receiving trough. The bottom of the water receiving tray cavity is evenly provided with hemispherical grooves. The double-layer arrangement of the fixed net causes water dripping from the upper portion to be splashed multiple times, thereby dispersing and reducing the volume of the water, thereby accelerating the vaporization of the water droplets. After vaporization, the water is discharged through the air vents along with the hot air, thereby accelerating the drying efficiency. The provision of the water receiving tray allows some water to remain in the hemispherical grooves as it flows along the inclined surface of the water receiving tray. Compared with water that accumulates entirely in the middle of the water receiving tray, the water in the hemispherical grooves can cause more water molecules to be disturbed under the same temperature energy, thereby accelerating vaporization and improving the drying efficiency.

[0004] In the above patent, the volume of water is dispersed and reduced by the double-layer setting of the fixed net, which can accelerate the vaporization of water droplets. After vaporization, the water droplets are discharged from the air vents with hot air, which can accelerate the drying efficiency. However, in actual use, the above patent uses a heating lamp to heat and dry the inside of the drying box, which cannot effectively control and adjust the temperature inside the drying box, resulting in the possibility of the temperature being too high or too low during the drying process of the medicinal materials. The staff needs to constantly adjust the temperature according to experience and actual conditions, and the operation process is relatively cumbersome. For this reason, the present application provides a constant temperature drying box. Utility Model Content

[0005] The purpose of this application is to solve the problem that the temperature inside the drying oven cannot be effectively controlled and adjusted, which may cause the temperature to be too high or too low during the drying process of medicinal materials.

This application provides a constant temperature drying oven.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a constant temperature drying oven.

[0035] Reference Figure 1 and Figure 2 A constant temperature drying oven includes a drying chamber 1, a heating chamber 2 is fixedly connected to one side of the drying chamber 1, a plurality of drying racks 5 are evenly slidably arranged inside the drying chamber 1, a glass door 6 is hinged on one side of the drying chamber 1, a temperature sensor 7 is fixedly connected inside the drying chamber 1, heating components 8 are symmetrically installed inside the heating chamber 2, an air guide component 9 is installed inside the heating chamber 2, a cleaning component 10 is installed on the glass door 6, a handle 11 is fixedly connected to the glass door 6, a controller 3 is fixedly connected to one side of the drying chamber 1, a plurality of operation buttons 4 are fixedly connected to one side of the drying chamber 1, the temperature sensor 7 is electrically connected to the controller 3, and a plurality of heat dissipation holes 12 are opened on one side of the heating chamber 2.

[0036] When in use, first open the glass door 6 through the handle 11, and then insert multiple drying racks 5 into the drying chamber 1 in turn. The drying chamber 1 is divided into multiple spaces by the multiple drying racks 5 to accommodate medicinal materials of different volumes. After the medicinal materials are classified and placed on the drying racks 5, the glass door 6 is closed. At this time, the working parameters are set and the heating component 8 is started through the controller 3 and the operation button 4. The heat generated by the heating component 8 is evenly transmitted to the inside of the drying chamber 1 through the transmission of the air guide component 9, so as to ensure that the medicinal materials are evenly dried. Secondly, when the medicinal materials in the drying chamber 1 are heated and dried, the temperature inside the drying chamber 1 can be monitored in real time through the internal temperature sensor 7. When the temperature is high, , the information is transmitted to the controller 3, and the controller 3 controls the heating component 8 to lower the heating temperature. When the temperature is low, the controller 3 controls the heating component 8 to increase the drying temperature. The controller 3 and the temperature sensor 7 cooperate to control and adjust the temperature inside the drying chamber 1 to ensure that the temperature is constant during the drying process, avoid affecting the quality of the medicinal materials due to temperature fluctuations, and greatly improve the drying effect of the medicinal materials. In addition, during the heating process of the medicinal materials, the water in the medicinal materials evaporates and produces water vapor that adheres to the inner wall of the glass door 6. At this time, the cleaning component 10 can be rotated to clean the inner wall of the glass door 6. The drying condition of the medicinal materials inside the drying chamber 1 can be directly observed through the cleaned glass door 6.

[0037] Reference Figure 1 and Figure 3The heating component 8 includes two heating chambers 81 symmetrically and fixedly connected to the inside of the heating chamber 2, and a plurality of parallel seats 82 are uniformly and symmetrically fixedly connected inside the two heating chambers 81. A heat pipe 83 is fixedly connected inside the plurality of parallel seats 82, and a resistance heating wire 84 is fixedly connected to the heat pipe 83. A plurality of fans 85 are fixedly connected on both sides of the heating chamber 81. The air guide component 9 includes a connecting pipe 91 that passes through and is fixedly connected to the opposite surfaces of the two heating chambers 81, and a plurality of transmission pipes 92 are uniformly fixedly connected to the connecting pipe 91. A blowing pipe 93 is fixedly connected to one side of the plurality of transmission pipes 92. One end of the blowing pipe 93 passes through and is fixedly connected to the inside of the drying chamber 1, and the resistance heating wire 84 and the fan 85 are electrically connected to the controller 3.

[0038] During use, after the medicinal materials are placed in the drying chamber 1, the controller 3 can start the operation of the resistance heating wire 84, and the heat generated by the resistance heating wire 84 is filled in the heating chamber 81 through the heat conduction of the heat pipe 83. At this time, the fan 85 is started to blow the heat inside the heating chamber 81 into the inside of the connecting pipe 91. After the heat enters the inside of the connecting pipe 91, the hot air is blown into the interior of the drying chamber 1 through the transmission guidance of the transmission pipe 92 and the blowing pipe 93. Since the blowing pipe 93 is located between the two drying racks 5, the hot air is evenly distributed in the drying chamber 1, ensuring uniform drying of the medicinal materials.

[0039] Reference Figure 4 and Figure 5 The cleaning assembly 10 includes a rotating rod 101 that is rotatably connected to the glass door 6, one end of the rotating rod 101 is fixedly connected to a knob 102, the end of the rotating rod 101 away from the knob 102 is fixedly connected to a connecting plate 103, one end of the connecting plate 103 is fixedly connected to a cleaning plate 104, a sealing gasket 105 is fixedly connected to the rotating rod 101, and limiting grooves are provided at the upper and lower ends of the connecting plate 103, and springs 106 are fixedly connected inside the limiting grooves. An adjusting block 107 is slidably connected inside the limiting groove, one end of the adjusting block 107 is fixedly connected to one end of the spring 106, and a clamping block 108 is fixedly connected to one side of the adjusting block 107. A clamping slot is provided at one end of the cleaning plate 104, and the clamping block 108 is slidably set inside the clamping slot.

[0040] During use, when heating medicinal materials, water in the medicinal materials evaporates and produces water vapor that adheres to the inner wall of the glass door 6. At this time, the knob 102 can be rotated to drive the rotating rod 101 and the connecting plate 103 to rotate together, so that the cleaning plate 104 rotates on the inner wall of the glass door 6 with the rotating rod 101 as the center. The rotating cleaning plate 104 can quickly clean the water vapor on the inner wall of the glass door 6, so that the staff can more conveniently observe the drying status of the medicinal materials in the drying chamber 1. At the same time, the sealing gasket 105 can prevent the heat in the drying chamber 1 from being lost.

[0041] Secondly, when the cleaning plate 104 needs to be replaced, the adjusting blocks 107 on both sides of the connecting plate 103 can be pressed to squeeze the two adjusting blocks 107 into the limit grooves. When the adjusting blocks 107 move, the card blocks 108 will be driven to move out of the card grooves, thereby releasing the connection between the connecting plate 103 and the cleaning plate 104. At this time, the cleaning plate 104 can be pulled out for replacement. When the new cleaning plate 104 is fitted with the connecting plate 103, the adjusting blocks 107 can be loosened. At this time, according to the rebound of the spring 106, the adjusting blocks 107 are pushed away from the limit grooves, thereby driving the card blocks 108 to re-enter the card grooves to fix the cleaning plate 104 on the connecting plate 103, thereby preventing the cleaning plate 104 from falling off during the cleaning process.

[0042] The implementation principle of a constant temperature drying oven in this embodiment is as follows: when in use, first open the glass door 6 through the handle 11, and then insert the multiple drying racks 5 into the drying chamber 1 in sequence. The multiple drying racks 5 divide the drying chamber 1 into multiple spaces to accommodate medicinal materials of different volumes. After the medicinal materials are classified and placed on the drying racks 5, the glass door 6 is closed. At this time, the operating parameters are set through the controller 3 and the operation button 4 and the resistance heating wire 84 is started to operate. The heat generated by the resistance heating wire 84 is filled into the heating chamber 81 through the heat conduction of the heat conduction pipe 83. At this time, the fan 85 is started to operate and the heat inside the heating chamber 81 is blown into the interior of the connecting pipe 91. After the heat enters the interior of the connecting pipe 91, the heat is transmitted and guided by the transmission pipe 92 and the blowing pipe 93 to blow the hot air into the interior of the drying chamber 1. Because the blowing pipe 93 is located between the two drying racks 5, the hot air is evenly distributed in the drying chamber 1, ensuring uniform drying of the medicinal materials.

[0043] Secondly, when the medicinal materials in the drying chamber 1 are heated and dried, the temperature inside the drying chamber 1 can be monitored in real time through the internal temperature sensor 7. When the temperature is high, the information is transmitted to the controller 3, and the controller 3 controls the heating component 8 to reduce the heating temperature. When the temperature is low, the controller 3 controls the heating component 8 to increase the drying temperature. The controller 3 and the temperature sensor 7 cooperate to control and adjust the temperature inside the drying chamber 1, ensuring that the temperature is constant during the drying process, avoiding the influence of temperature fluctuation on the quality of the medicinal materials, and greatly improving the drying effect of the medicinal materials.

[0044] In addition, during the heating process of the medicinal materials, the water vapor generated by the evaporation of the medicinal materials will adhere to the inner wall of the glass door 6. At this time, the knob 102 can be rotated to drive the rotating rod 101 and the connecting plate 103 to rotate together, so that the cleaning plate 104 can rotate on the inner wall of the glass door 6 with the rotating rod 101 as the center. The rotating cleaning plate 104 can quickly clean the water vapor on the inner wall of the glass door 6, so that the staff can more conveniently observe the drying status of the medicinal materials in the drying chamber 1. At the same time, the sealing gasket 105 can prevent the heat from being lost in the drying chamber 1. When the cleaning plate 104 needs to be replaced, it can be replaced. When the adjusting blocks 107 on both sides of the connecting plate 103 are pressed, the two adjusting blocks 107 are squeezed into the limiting grooves. When the adjusting blocks 107 move, the card blocks 108 are driven to move out of the card slots, thereby releasing the connection between the connecting plate 103 and the cleaning plate 104. At this time, the cleaning plate 104 can be pulled out for replacement. When the new cleaning plate 104 is fitted with the connecting plate 103, the adjusting blocks 107 can be loosened. At this time, according to the rebound of the spring 106, the adjusting blocks 107 are pushed away from the limiting grooves, thereby driving the card blocks 108 to re-enter the card slots to fix the cleaning plate 104 on the connecting plate 103, thereby preventing the cleaning plate 104 from falling off during the cleaning process.
