Description

Technical Field

[0001] This utility model relates to the field of chemical testing technology, and in particular to a drying oven for chemical testing with a scalding-proof structure. Background Technology

[0002] In chemical testing, drying ovens are used to remove moisture, solvents, and other volatile substances from samples to ensure the accuracy of test results. For example, drying chemical raw materials, intermediates, or finished products before chemical analysis or material performance testing is an indispensable key piece of equipment in the chemical testing process.

[0003] In daily work, it has been found that existing chemical testing drying ovens are usually equipped with multiple shelves inside to place various items to be tested for drying. When the drying process is over and the operator needs to retrieve the items, the space between adjacent shelves is extremely narrow. Because the internal temperature of the drying oven is high during operation, the shelves are also at a high temperature. In this confined space, operators are prone to accidentally touching adjacent shelves, which can lead to burns. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the space between adjacent racks is extremely narrow, and the racks are also in a high-temperature state when the drying oven is working, making it easy to get burned when taking them out. Therefore, this invention proposes a chemical testing drying oven with an anti-scalding structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drying oven for chemical testing with an anti-scalding structure, comprising a drying oven body, a door provided on the surface of the drying oven body, a handle fixedly connected to the surface of the door, a protective device provided on the inner wall of the drying oven body, the protective device comprising multiple fixing blocks fixed in the inner wall of the drying oven body, a placement rack slidably connected to the inner wall of the fixing blocks, a driving unit provided between the drying oven body and the placement rack, and a blowing assembly provided on the surface of the drying oven body. Through the above components, when the drying is completed and the item is to be taken out, the driving unit controls the corresponding placement rack to move within the fixing blocks, thereby bringing the item out. This prevents contact with the placement rack during retrieval, thus preventing scalding.

[0006] Preferably, the driving unit includes a driving screw rotatably connected to the inner wall of the drying chamber, the driving screw being threadedly connected to the inner wall of the placement rack, a driving motor being fixedly connected to the surface of the drying chamber, and the output end of the driving motor being fixedly connected to one end of the driving screw. Through the above components, when the driving motor is turned on, the driving motor can drive the driving screw to rotate, and the driving screw can control the placement rack to move within the inner wall of the fixed block.

[0007] Preferably, two sliding rods are fixedly connected to the surface of the placement rack, and a connecting block is fixedly connected to one side of each of the two fixed blocks. The sliding rods are slidably connected to the inner wall of the connecting block. Through the above components, when the placement rack moves within the inner wall of the fixed block, the sliding rods can move within the connecting block, thereby providing support for the placement rack.

[0008] Preferably, a protective cover is fixedly connected to one side surface of the drying chamber by screws. Through the above-mentioned components, the protective cover can shield and protect multiple sets of drive motors.

[0009] Preferably, the blowing assembly includes an air pump fixed to the surface of the drying chamber, and a blower head fixedly connected to the inner wall of the drying chamber. The input end and output end of the air pump are respectively fixedly connected to pipe two and pipe one. The other end of pipe one is connected to the blower head. Through the above components, when the rack is moved out, the air pump can be turned on. The air pump can draw in air through pipe two and supply it to the blower head through pipe one. The blower head can blow air to cool down the rack and the items, further reducing the chance of burns.

[0010] Preferably, the inner wall of the second pipe is threaded with a connector, and the inner wall of the connector is fixedly connected with a filter screen. Through the above components, the connector can be threadedly connected to the second pipe, and the filter screen can then play a certain role in dust prevention.

[0011] Preferably, the surface of the blower head has multiple air outlets arranged at equal intervals.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting an auxiliary device, the drive unit controls the placement rack to move within the fixed block. When the operator retrieves items, the placement rack and items are carried out of the drying chamber, eliminating the need to retrieve items in a narrow, high-temperature space. This greatly reduces the risk of burns, ensures the safety of the operator, and reduces work interruptions and physical injuries caused by burns.

[0014] In this invention, the sliding connection between the slide rod and the connecting block provides stable support during movement, ensuring the smooth operation of the placement rack.

[0015] In this invention, by setting up a blower assembly, the air pump, pipe one, pipe two and blower head work together to blow air and cool down the moving rack and items, further reducing the temperature when picking them up and reducing the chance of burns. At the same time, rapid cooling helps with subsequent testing and analysis of the items and improves work efficiency. Attached Figure Description
