Description

Technical Field

[0001] This utility model relates to the field of drying oven technology, and in particular to an electric heating forced-air drying oven with a cleaning structure. Background Technology

[0002] Electric heating drying ovens are indispensable equipment in industrial production, scientific research experiments, and many other fields requiring drying processes. They use electric blowers to generate hot air, which is then used to dry items placed inside the oven. They are widely used in industries such as chemical, pharmaceutical, food, and electronics. However, existing electric heating drying ovens suffer from several problems that urgently need to be addressed in practical use. These problems severely affect the drying effect, production efficiency, and lifespan of the equipment.

[0003] Currently, most electric heating drying ovens on the market have complex and cumbersome connection structures between the main body and the mounting plate. Traditional connection methods may use a large number of bolts for fixing, requiring operators to tighten each bolt individually during installation. This is not only time-consuming and labor-intensive but also demands a high level of skill from the operators. If even one bolt is not tightened properly, the connection may be weak, affecting the overall stability of the equipment.

[0004] When equipment requires maintenance, repair, or replacement of critical components, such as electric blowers, the disassembly process is fraught with difficulties. Operators must first loosen each bolt individually, then carefully separate the mounting plate from the drying chamber body. This process is not only time-consuming and labor-intensive, but also prone to damaging components due to improper operation. Moreover, during reinstallation, each bolt must be tightened again to ensure a secure connection, which undoubtedly further increases maintenance time and costs. For companies that require frequent maintenance or component replacement, this inefficient disassembly and assembly method severely impacts production schedules, reduces production efficiency, and increases operating costs.

[0005] During the operation of an electric heating forced-air drying oven, outside air enters the oven body through the air inlet. However, outside air often contains a large amount of dust, impurities, and other contaminants. Most existing drying ovens lack effective filtration and cleaning structures, allowing these contaminants to enter the oven with the air and adhere to the surface of the items being dried, severely affecting the drying quality. For example, during food drying, the adhesion of dust and impurities may contaminate the food, affecting its safety and quality; during the drying of electronic components, dust and impurities may affect the performance and reliability of the components.

[0006] Furthermore, even if some drying ovens are equipped with filter screens, the lack of an effective cleaning mechanism leads to the gradual accumulation of dust and impurities on the filter screens over time, causing them to become clogged. Clogged filter screens severely impair ventilation, preventing the hot air generated by the electric blower from being evenly distributed within the drying oven, resulting in uneven drying and reduced efficiency. Simultaneously, poor ventilation increases the workload of the electric blower, leading to increased energy consumption and potentially causing damage due to overheating, shortening the equipment's lifespan and increasing replacement costs for businesses. Therefore, we provide an electric blower drying oven with a cleanable structure. Utility Model Content

[0007] To address the aforementioned problems, this invention proposes an electric heating drying oven with a clean structure, which more accurately solves the problems mentioned in the background art.

[0008] This utility model is achieved through the following technical solution:

[0009] The utility model proposes an electric heating blower drying oven with a clean structure, including a drying oven body and a mounting plate. The mounting plate is installed on the side of the drying oven body, and an electric heating blower is fixedly installed on the upper surface of the mounting plate. The drying oven body is rotatably connected to a sealed opening and closing door via a hinge. A through groove is opened on the side of the drying oven body for connecting the electric heating blower. A disassembly and assembly mechanism is connected between the drying oven body and the mounting plate.

[0010] The disassembly and assembly mechanism includes a docking block fixedly installed on the side of the drying oven body and an opening groove opened on the surface of the mounting plate. One end of the docking block is provided with a limit insertion hole. A rectangular groove is provided on the surface of the mounting plate. A moving block is slidably connected to the inner wall of the rectangular groove. A limit insertion rod is fixedly connected to the surface of the moving block.

[0011] Furthermore, a plug-in rod is inserted into the end wall of the rectangular groove, and one end is fixedly connected to the surface of the moving block. A spring is sleeved around the plug-in rod, and a guide structure connects the rectangular groove and the moving block.

[0012] Furthermore, the guide slide structure includes a guide slide groove formed on the inner sidewall of the rectangular groove and guide slide blocks fixedly connected to the surfaces at both ends of the movable block, and the guide slide blocks are slidably connected to the inner wall of the guide slide groove.

[0013] Furthermore, a placement rack and a U-shaped plate are fixedly installed on the inner wall of the drying oven body, a filter screen is inserted into the inner wall of the U-shaped plate, and a cleaning brush is fixedly installed directly below the filter screen and on the inner wall of the drying oven body for cleaning when the filter screen is pulled out.

[0014] Furthermore, the mating block is inserted into the inner wall of the opening groove, one end of the limiting rod passes through the end wall of the rectangular groove and is inserted into the inner wall of the limiting hole, and the inner diameter of the limiting hole is adapted to the outer diameter of the limiting rod.

[0015] Furthermore, one end of the spring is fixedly connected to the end wall of the rectangular groove, and the other end of the spring is fixedly connected to the surface of the movable block.

[0016] The beneficial effects of this utility model are:

[0017] This invention achieves a convenient and stable connection between the drying oven body and the mounting plate through a disassembly and assembly mechanism. During installation, simply insert the mating block on the side of the drying oven body into the opening slot on the surface of the mounting plate, then push the insertion rod to move the moving block within the rectangular groove, allowing the limiting rod to insert into the limiting insertion hole of the mating block, thus completing the connection. During disassembly, releasing the insertion rod causes the spring force to return the moving block to its original position, disengaging the limiting rod from the limiting insertion hole, easily separating the mating block from the opening slot. This convenient disassembly and assembly method significantly shortens the installation and disassembly time, reduces operational difficulty, and can be completed without specialized technicians. When the equipment requires maintenance, repair, or replacement of components such as the electric heating blower, quick disassembly and assembly can be performed, improving equipment maintenance efficiency, reducing downtime, thereby increasing production efficiency and reducing enterprise operating costs.

[0018] This invention utilizes a filter screen inserted into a U-shaped plate to effectively filter dust and impurities from the air entering the drying chamber, preventing these contaminants from adhering to the dried items and affecting drying quality. Simultaneously, a cleaning brush installed directly below the filter screen automatically cleans its surface when the screen is pulled out, removing dust and impurities and preventing airflow obstruction due to filter clogging. This not only ensures the cleanliness of the air inside the drying chamber and improves drying efficiency but also extends the lifespan of the filter screen and reduces the frequency of replacement.

[0025] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details. Example

[0026] like Figures 1-5 As shown in the figure, an embodiment of the present invention discloses an electric heating drying oven with a clean structure. Its main structure includes a drying oven body 1 and a mounting plate 2. The mounting plate 2 is installed on the side of the drying oven body 1 by bolts or other means. An electric heating blower 3 is installed on the upper surface of the mounting plate 2 by welding or bolt fixing. The drying oven body 1 is connected to a sealed opening and closing door 4 via a hinge for easy loading and unloading of items. A through groove 9 is provided on the side of the drying oven body 1. The position and size of the through groove 9 are adapted to the air outlet of the electric heating blower 3 for docking with the electric heating blower 3, allowing the hot air generated by the electric heating blower 3 to smoothly enter the drying oven body 1. A disassembly and assembly mechanism connects the drying oven body 1 and the mounting plate 2. Specifically, a docking block 10 is fixedly installed on the side of the drying oven body 1 by welding or other means. An opening groove 11 is provided on the surface of the mounting plate 2. The size of the docking block 10 matches the opening groove 11, and a limit insertion hole 12 is provided at one end of the docking block 10. A rectangular groove 13 is formed on the surface of the mounting plate 2. A movable block 14 is slidably connected to the inner wall of the rectangular groove 13. The movable block 14 can slide in a specific direction within the rectangular groove 13. A limiting rod 15 is fixedly connected to the surface of the movable block 14 by welding or other means. In actual installation, the mating block 10 is inserted into the opening groove 11, and then the movable block 14 is pushed so that one end of the limiting rod 15 is inserted into the limiting hole 12, thereby achieving the connection and fixation between the drying oven body 1 and the mounting plate 2. When disassembly is required, the movable block 14 is pulled in the opposite direction to disengage the limiting rod 15 from the limiting hole 12, and the mating block 10 can be removed from the opening groove 11, completing the disassembly of the drying oven body 1 and the mounting plate 2.

[0027] Furthermore, a pull rod 16 is inserted into the end wall of the rectangular groove 13. One end of the pull rod 16 is fixedly connected to the surface of the movable block 14 by welding or other means. The operator can pull or push the pull rod 16 to make the movable block 14 slide within the rectangular groove 13. A spring 17 is sleeved around the pull rod 16, and the spring 17 is in a certain state of compression or tension. When the pull rod 16 is pushed to insert the limiting rod 15 into the limiting socket 12, the spring 17 is further compressed or stretched, generating elastic force. When disassembly is required, the pull rod 16 is released, and the elastic force of the spring 17 will cause the movable block 14 to return to its original position, causing the limiting rod 15 to disengage from the limiting socket 12. At the same time, a guide structure is connected between the rectangular groove 13 and the movable block 14 to ensure the stability and accuracy of the sliding of the movable block 14.

[0028] Furthermore, the guide structure specifically includes a guide groove 18 formed on the inner wall of the rectangular groove 13 and guide sliders 19 fixedly connected to the two end surfaces of the movable block 14. The guide sliders 19 are fixed to the two end surfaces of the movable block 14 by welding or other methods. The size of the guide sliders 19 matches the guide groove 18, and the guide sliders 19 are slidably connected to the inner wall of the guide groove 18. When the movable block 14 slides within the rectangular groove 13, the guide sliders 19 slide along the guide groove 18, thereby guiding and limiting the sliding of the movable block 14, ensuring that the movable block 14 can slide smoothly and accurately, avoiding deviation or jamming, and ensuring that the limiting insertion rod 15 can smoothly insert into or disengage from the limiting insertion hole 12.

[0029] Furthermore, a shelf 5 and a U-shaped plate 6 are installed on the inner wall of the drying chamber body 1 by welding or bolting. The shelf 5 is used to place items to be dried, and a filter screen 7 is inserted into the inner wall of the U-shaped plate 6. The filter screen 7 can be easily inserted into or removed from the U-shaped plate 6. A cleaning brush 8 is installed directly below the filter screen 7 and on the inner wall of the drying chamber body 1 by welding or bolting. When it is necessary to clean the filter screen 7, simply pull the filter screen 7 out of the U-shaped plate 6. During the pulling process, the cleaning brush 8 will clean the surface of the filter screen 7, removing dust, impurities, etc., adhering to the filter screen 7, thereby ensuring the filtration effect of the filter screen 7, extending its service life, and also ensuring the cleanliness of the air inside the drying chamber body 1.

[0030] Furthermore, the mating block 10 is inserted into the inner wall of the opening groove 11, and the size of the mating block 10 is tightly fitted with the opening groove 11 to ensure the stability of the connection. One end of the limiting rod 15 penetrates the end wall of the rectangular groove 13 and is inserted into the inner wall of the limiting hole 12. The inner diameter of the limiting hole 12 is matched with the outer diameter of the limiting rod 15, so that the limiting rod 15 can be tightly inserted into the limiting hole 12, thereby effectively restricting the movement of the mating block 10 in the opening groove 11 and realizing a stable connection between the drying oven body 1 and the mounting plate 2. When disassembly is required, simply pull the limiting rod 15 to disengage it from the limiting hole 12 to release the restriction on the mating block 10 and easily remove the mating block 10 from the opening groove 11.

[0031] Furthermore, one end of the spring 17 is fixedly connected to the end wall of the rectangular groove 13 by welding or other means, and the other end of the spring 17 is fixedly connected to the surface of the moving block 14 by welding or other means. When the insertion rod 16 is pushed to slide the moving block 14, the spring 17 is compressed or stretched, generating elastic force. When it is necessary to disassemble the drying oven body 1 and the mounting plate 2, the insertion rod 16 is released, and the elastic force of the spring 17 will cause the moving block 14 to reset, driving the limiting insertion rod 15 to disengage from the limiting insertion hole 12, thereby realizing the automatic reset function, which is convenient and quick, and improves the disassembly and assembly efficiency.
