Description

Technical Field

[0001] This application relates to the technical field of building material testing equipment, specifically an electric heating drying oven. Background Technology

[0002] As the construction industry continues to raise its requirements for material quality, the quality testing of building materials such as gypsum board has become particularly important. Gypsum board contains a certain amount of moisture, which can affect the accuracy of test results. Placing gypsum board samples in an electric heating drying oven and drying them to constant weight at a specified temperature can effectively remove moisture and bring the samples to the standard testing state.

[0003] An existing patent (publication number: CN215490816U) discloses an electric heating forced-air drying oven, including a drying oven with a vertically arranged mounting plate inside. A heater is located on the top of the mounting plate. The heater and mounting plate divide the interior of the drying oven into a heating chamber and a drying chamber. The heating chamber is located on the left side of the drying chamber. A movable platform is slidably arranged inside the drying chamber. A circular groove is formed in the movable platform, and a bearing is connected to the circular groove. A placement platform is connected to the inner ring of the bearing, and a first drive motor is connected to the lower surface of the placement platform. This utility model provides an electric heating forced-air drying oven where a first drive motor drives a concrete sample on the placement platform to rotate, ensuring uniform drying. After drying, a second drive motor drives a screw to rotate. The screw engages with a threaded hole in a slider, causing the first drive motor on the slider to move the concrete sample out of the drying oven for easy removal.

[0004] However, it was found in the above solution that the drying process of gypsum board could not achieve circulating drying, which reduced the drying efficiency and caused energy waste. Furthermore, the heated air would carry moisture after drying the gypsum board, and if the humid air could not be discharged quickly, it would cause pollution to the gypsum board. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an electric heating forced-air drying oven, which has the advantages of achieving efficient drying through circulation while preventing excessive humidity from contaminating gypsum board. This solves the problems of gypsum board drying processes where the inability to circulate the drying process reduces drying efficiency, wastes energy, and causes contamination of the gypsum board when the humid air inside the drying oven cannot be discharged quickly.

[0006] To achieve the above objectives, this application provides the following technical solution: an electric heating forced-air drying oven, comprising a drying oven body, a humidity sensor fixedly installed on the inner wall of the drying oven body, a partition and an inclined plate fixedly connected to the inner wall of the drying oven body, an air inlet pipe fixedly installed on the left side of the drying oven body, an air inlet fan fixedly installed at the right end of the air inlet pipe, the outer surface of the air inlet fan fixedly connected to the inner wall of the partition, a heating wire provided on the inner wall of the drying oven body, a circulation pipe fixedly connected to the outer surface of the air inlet pipe, the outer surface of the circulation pipe fixedly connected to the inner wall of the drying oven body and the left side of the partition, an exhaust head fixedly installed on the upper surface of the drying oven body, an exhaust pipe fixedly connected to the upper surface of the exhaust head, an exhaust fan fixedly installed at the right end of the exhaust pipe, and an air outlet pipe fixedly connected to the output end of the exhaust fan.

[0007] To improve drying efficiency, the above solution involves the following steps: When the humidity sensor detects normal humidity, the intake fan draws outside air into the drying chamber through the intake duct. Heated by the heating wire, the hot air rises to dry the gypsum board. As the hot air rises, it is transferred to the left side of the drying chamber via an inclined plate installed on the inner wall. The hot air then enters the left side of the partition and is recirculated by the intake fan to the heating wire position. When the humidity sensor detects humidity exceeding a set value, the exhaust fan activates, drawing out the humid air from inside the drying chamber through the exhaust head and duct. This prevents the high humidity from affecting the drying process, thus improving drying efficiency and preventing contamination of the gypsum board.

[0008] Furthermore, a door is installed on the front of the main body of the drying oven, a handle is fixedly connected to the front of the door, and an observation window is provided on the inner wall of the door.

[0009] The above solution involves installing the door on the front of the drying oven body, allowing the drying oven body to be opened and closed by opening and closing the door. A handle facilitates the operation of opening and closing the door, and an observation window is set on the inner wall of the door, allowing the operator to observe the drying status of the gypsum board.

[0010] Furthermore, support rods are fixedly connected to the right side of the partition and the inner wall of the drying oven body, and two guide rods are fixedly connected to the upper surface of each support rod.

[0011] The above method involves installing support rods on the right side of the partition and the inner wall of the drying oven body to achieve the positioning and installation of the support rods. The guide rods are then fixed to the upper surface of the corresponding support rods, forming a fixed connection to achieve the installation of the guide rods.

[0012] Furthermore, the interior of the drying oven body is provided with a shelf, and guide blocks are fixedly connected to the left and right sides of the shelf. The inner wall of each guide block is slidably connected to the outer surface of the corresponding guide rod.

[0013] The above scheme involves placing a shelf inside the main body of the drying oven to hold gypsum board samples. Guide blocks are installed on the left and right sides of the shelf for fixed connection, and the inner walls of the guide blocks are connected to the corresponding guide rods for sliding connection, thereby enabling the shelf to be positioned.

[0014] Furthermore, limit rods are fixedly connected to the right side of the partition and the inner wall of the drying oven body, and the top of each guide rod is fixedly connected to the bottom surface of the corresponding limit rod.

[0015] The above solution involves installing limiting rods on the right side of the partition and the inner wall of the drying oven body to achieve positioning of the limiting rods. The top of the corresponding guide rod is connected to the corresponding limiting rod to limit the top of the guide rod.

[0016] Furthermore, a limiting component is fixedly connected to the upper surface of one of the limiting rods, a rotating rod is rotatably connected to the inner wall of the limiting component, and a bevel gear is fixedly connected to the back of the rotating rod.

[0017] The above scheme involves installing the limiting component on the upper surface of the left limiting rod as a fixed connection to achieve the installation of the limiting component, installing the rotating rod on the inner wall of the limiting component as a rotatable connection to achieve the limiting of the rotating rod, and installing a bevel gear at the rear end of the rotating rod so that the rotation of the bevel gear can be achieved by rotating the rotating rod.

[0018] Furthermore, a second bevel gear meshes with the outer surface of the first bevel gear, and a threaded rod is fixedly connected to the bottom surface of the second bevel gear. The outer surface of the threaded rod is rotatably connected to the inner wall of the corresponding limiting rod.

[0019] The above scheme involves placing bevel gear 2 on the side of bevel gear 1 and connecting bevel gear 1 and bevel gear 2. The rotation of bevel gear 1 allows bevel gear 2 to rotate. A threaded rod is installed on the bottom surface of bevel gear 2. When bevel gear 2 rotates, the threaded rod rotates with it. The surface of the threaded rod is connected to the corresponding limiting rod, forming a rotating connection to achieve the limiting effect on the threaded rod.

[0020] Furthermore, the outer surface of the threaded rod is threaded with a threaded block, and the right side of the threaded block is fixedly connected to the left side of the shelf.

[0021] The above scheme involves installing a threaded block on the surface of a threaded rod to form a threaded connection, and connecting the right side of the threaded block to the left side of the shelf to form a fixed connection. When the threaded rod rotates, the threaded block can drive the shelf to rise and fall, making it easy to adjust the height of the shelf according to different sizes of gypsum board.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This electric heating forced-air drying oven incorporates components such as a humidity sensor, inclined plate, and circulation pipe. External air is drawn in via an inlet fan and inlet pipe, heated by a heating wire, and then the hot air rises to dry the gypsum board. The inclined plate guides the hot air to the left side of the partition. The connection between the inlet pipe and circulation pipe allows the hot air to be drawn in by the inlet fan for circulating drying. When the humidity sensor detects that the humidity exceeds a set value, the exhaust fan is activated, allowing the excessively humid air to be expelled through the exhaust pipe. This achieves efficient drying and prevents excessively humid air from contaminating the gypsum board. Rotating the rotating rod causes bevel gear one to rotate, which in turn causes bevel gear two to rotate. This causes the threaded rod to rotate and drive the threaded block to rise and fall, thereby raising and lowering the shelf to accommodate adjustments based on the size of the gypsum board.

[0037] Please see Figure 5 One of the limiting rods 20 has a limiting component 21 fixedly connected to its upper surface.

[0040] This embodiment of an electric heating drying oven includes a humidity sensor 2, an inclined plate 6, and a circulation pipe 7. External air is drawn in via an intake fan 4 and an intake pipe 3, heated by a heating wire 12, and then the hot air rises to dry the gypsum board. The inclined plate 6 guides the hot air to the left side of the partition 5. The connection between the intake pipe 3 and the circulation pipe 7 allows the hot air to be introduced by the intake fan 4 for circulating drying. When the humidity sensor 2 detects that the humidity exceeds a set value, the exhaust fan 10 is activated. The exhaust head 8 and exhaust pipe 9 allow the excessively humid air to be discharged through the exhaust pipe 11, achieving efficient drying and preventing contamination of the gypsum board by excessively humid air. Rotating the rotating rod 22 causes the first bevel gear 23 to rotate, which in turn causes the second bevel gear 24 to rotate. At this time, the threaded rod 25 rotates and drives the threaded block 26 to rise and fall, thereby raising and lowering the shelf 19, allowing for adjustment of the shelf 19's height according to the size of the gypsum board.

[0041] It should be noted that the observation window 15 is made of tempered glass, which can withstand high temperatures and has good impact resistance.

[0042] The working principle of the above embodiments is as follows:

[0043] By observing the dimensions of the gypsum board, rotating the rotating rod 22 causes the first bevel gear 23 to rotate, which in turn causes the second bevel gear 24 to rotate. The second bevel gear 24 drives the threaded rod 25 to rotate. With the threaded rod 25 connected to the threaded block 26, the shelf 19 can drive the corresponding guide block 18 to rise and fall on the surface of the guide rod 17. After adjusting the height of the shelf 19, the gypsum board is placed on the shelf 19, and then the door 13 is closed. The inlet fan 4 is started, and the outside air can enter the drying chamber body 1 through the air inlet pipe 3. The air is heated by the heating wire 12, and then the air rises to dry the gypsum board. The inclined plate 6 guides the air to the left side of the partition 5. With the connection between the circulation pipe 7 and the air inlet pipe 3, the air can circulate, improving the drying efficiency. When the humidity sensor 2 detects that the humidity is higher than the set value, the exhaust fan 10 is started. The high humidity air inside the drying chamber body 1 can be extracted through the exhaust head 8 and the exhaust pipe 9, and then discharged through the exhaust pipe 11, which can prevent the high humidity air from contaminating the gypsum board.
