Abstract
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. Background Technology
[0002] The electric heating drying oven uses electric heating to conduct circulating drying tests. It is divided into two types: forced air drying and vacuum drying. Forced air drying involves blowing hot air out by a circulating fan. The hot air comes into contact with the sample to dry it, ensuring a balanced temperature inside the oven. It is mainly used to dry samples.
[0003] The announcement number is CN218821551U, and the name is an electric heating forced-air drying oven. It includes an oven body, a rotary drive component, a hot air structure, an insulation plate, and a mesh tray. By freely setting the insulation plate and the mesh tray, and cooperating with the rotary drive component to adjust the rotation of the hot air structure, it is divided into a concentrated hot air drying mode for the middle layer and a normal three-layer drying mode. This mode is adapted to the efficient drying of a small number of samples and the normal simultaneous drying of a large number of samples, respectively, thereby improving the utilization rate of hot air and increasing the drying efficiency of a small number of samples.
[0004] However, the aforementioned drying oven is equipped with multi-layer mesh trays, which hold different types and quantities of samples. Different types of samples require different drying times. However, the samples on the multi-layer mesh trays are connected, and the hot air outlet position is fixed. In order to ensure that the samples in the oven are completely dry, the drying time needs to be increased. However, samples that are dried for a short time are affected, resulting in excessive drying of samples that are dried for a short time. Utility Model Content
[0005] The purpose of this invention is to provide an electric heating forced-air drying oven, which aims to improve the above-mentioned problems.
[0006] This utility model is implemented as follows:
[0007] An electric heating drying oven includes a drying component and a heating component. The drying component includes a cabinet with an opening on the front vertical end face of the cabinet, and a cabinet door is rotatably installed on the opening end of the cabinet. Multiple partitions are horizontally fixed in the vertical direction inside the cabinet, and the interior of the cabinet is divided into multiple placement chambers by the multiple partitions. Multiple air inlet pipes are horizontally arranged in the vertical direction on the rear end face of the cabinet, and one end of each air inlet pipe passes through multiple placement chambers and is fixed to the rear end face of the cabinet. The heating component includes a sliding frame, which is vertically fixed to the rear end face of the cabinet, and a lifting plate is vertically slidably installed in the sliding frame. A heating cylinder is horizontally fixed in the sliding frame, and one end of the heating cylinder is connected to and fixedly connected to an air suction pipe. The other end of the heating cylinder is connected to and fixedly connected to a corrugated pipe, and the other end of the corrugated pipe passes through and is fixedly connected to a sleeve, which is sleeved on the air inlet pipe to guide hot air into the placement chambers of the cabinet.
[0008] Furthermore, multiple through holes are vertically oriented on the cabinet door, and each through hole corresponds to a different placement cavity. A perforated plate is fixed in each of the through holes of the cabinet door.
[0009] Furthermore, multiple heating rods are horizontally and evenly arranged in the heating cylinder, and these heating rods are fixed to the inner end face of the heating cylinder.
[0010] Furthermore, a mesh cover is fixed through the end of the air intake pipe of the heating cylinder, and an air pump is connected and installed on the air intake pipe of the heating cylinder.
[0011] Furthermore, a rod is horizontally slidably installed on the front end face of the lifting plate, and a sleeve is fixed through the rod.
[0012] Furthermore, an electric telescopic rod is horizontally fixed on the top surface of the lifting platform, and the output end of the electric telescopic rod is fixed on the rod frame.
[0013] Furthermore, a screw rod is installed vertically through the top surface of the sliding frame, and the bottom end of the screw rod is rotatably connected to the lifting plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, different types of samples are placed in different placement chambers in the cabinet, and then the cabinet door is closed. During heating, the sliding lifting plate moves vertically up and down in the sliding frame to different placement chamber heights. Then, the sleeve is fitted onto the air inlet pipe of the cabinet, and the air pump on the air suction pipe at the end of the heating cylinder is started to drive air into the heating cylinder. After the air is heated, it is guided to the placement chamber of the cabinet through the corrugated pipe. After the hot air comes into contact with the sample and dries it, the air is discharged from the perforated plate of the corresponding placement chamber in the cabinet door. Thus, different types of samples require different drying times. Multiple placement chambers are set up to place samples in a connected manner, and the air outlet position of the hot air structure can be moved to each placement chamber to guide hot air for heating and drying. This avoids the need to increase the drying time in order to keep the samples in the chamber completely dry, but samples that are dried for a short time are affected, resulting in a transition in the drying effect of short-time samples. This improves the selectivity of drying different types of samples. Attached Figure Description

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an electric heating drying oven includes a drying element 1 and a heating element 2. The drying element 1 includes a cabinet 11 with an opening on the front vertical end face of the cabinet 11, and a cabinet door 15 is rotatably installed on the opening end of the cabinet 11. Multiple partitions 12 are horizontally fixed vertically inside the cabinet 11, dividing the interior of the cabinet 11 into multiple placement chambers 13. Multiple air inlet pipes 14 are horizontally arranged vertically on the rear end face of the cabinet 11, with one end of each air inlet pipe 14 passing through multiple placement chambers 13 and fixed to the rear end face of the cabinet 11. The heating element 2 includes a sliding frame 2. 1. A sliding frame 21 is vertically fixed to the rear end face of the cabinet 11, and a lifting plate 23 is vertically slidably installed in the sliding frame 21. A heating cylinder 24 is horizontally fixed in the sliding frame 21, and one end of the heating cylinder 24 is connected to and fixedly connected to an air intake pipe 25. The other end of the heating cylinder 24 is connected to and fixedly connected to a corrugated pipe 26, and the other end of the corrugated pipe 26 is fixedly connected to a sleeve 28. The sleeve 28 is fitted onto the air intake pipe 14 to guide hot air into the placement cavity 13 of the cabinet 11. Multiple through holes are opened vertically on the cabinet door 15, and the multiple through holes on the cabinet door 15 correspond one-to-one with the multiple placement cavities 13. A perforated plate 16 is fixed in the through hole of the cabinet door 15. During use, different types of samples are placed in different placement chambers 13 in the cabinet body 11, and then the cabinet door 15 is closed. During heating, the sliding lifting plate 23 moves vertically up and down in the sliding frame 21 to different placement chamber heights. Then, the sleeve 28 is fitted onto the air inlet pipe 14 of the cabinet body 11, and the air pump 251 on the air suction pipe 25 at the end of the heating cylinder 24 is started to drive air into the heating cylinder 24.
