Description

Technical Field

[0001] The utility model relates to the technical field of constant-temperature air-blast drying, in particular to an electrothermal constant-temperature air-blast drying oven. Background Technique

[0002] Drying ovens are divided into two categories: electrothermal air-blast drying ovens and vacuum drying ovens according to different drying substances. Nowadays, they have been widely used in industries such as chemical industry, electronic communication, plastics, cables, electroplating, hardware, automobiles, optoelectronics, rubber products, molds, spraying, printing, medical treatment, aerospace and institutions of higher learning. With the increasing variety of materials to be dried, the usage functions of drying ovens are gradually increasing, making them more convenient and efficient to use.

[0003] In view of this, Chinese Patent No. CN210862090U proposes an electrothermal constant-temperature air-blast drying oven. For the electrothermal constant-temperature air-blast drying oven described in the utility model, by setting a placing structure and cooperating with a blower, it is beneficial to the uniformity of drying and improves the drying effect. By setting an ash storage structure, it is convenient to clean the dust inside later;

[0004] However, the above technical solution is very effective for drying materials with a large volume that are placed in the placing tray without stacking. If the materials to be dried are small in volume or small granular materials that cannot leak out from the holes, the materials will stack together when placed. If the placing tray is simply rotated for diversion, not all materials can be evenly heated and dried, and the extrusion area between the materials cannot even be dried, affecting the drying effect of the materials. In view of this, this design scheme proposes an electrothermal constant-temperature air-blast drying oven. Content of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide an electrothermal constant-temperature air-blast drying oven to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model proposes an electrothermal constant-temperature air-blast drying oven, including a box body and a supporting mechanism installed inside the box body;

[0007] The supporting mechanism includes a mounting backing plate fixed on one side of the inner wall of the box body. Three support frames are equidistantly fixed on one side of the mounting backing plate. One end of each of the three support frames is fixedly provided with a sleeve. A receiving groove is opened at the lower end of one side of each sleeve. A scraping plate is rotatably provided at the lower end of the inner wall of each receiving groove. A rotating shaft is rotatably provided at the middle position of the inner wall of the box body, and the outer wall of the rotating shaft is respectively inserted and connected with the inner walls of the three sleeves. The outer wall of the rotating shaft is equidistantly fixed with placing trays. Through holes are opened at the top of each placing tray. One end of the rotating shaft passes through the top of the box body and is connected with a motor.

[0008] In one example, a sealing cover is hingedly arranged on one side of the inner wall of the box body, and installation grooves are formed on both sides of the inner wall of the box body.

[0009] In one example, a plurality of electric heating wires are installed on the inner walls of the two installation grooves, and a blower is installed at the lower edge of the back surface of the box body.

[0010] In one example, a groove is formed on one side of the top of the box body, and a plurality of exhaust grooves are equidistantly formed at the bottom of the inner wall of the groove, and the inner wall of each exhaust groove is communicated with the inner wall of the box body.

[0011] In one example, a sealing plate is inserted at the upper edge of one side of the box body, and the outer wall of the sealing plate is inserted and connected with the inner wall of the groove. A plurality of heat dissipation holes are equidistantly formed on both sides of the inner wall of the box body, and the inner wall of each heat dissipation hole is respectively communicated with the inner walls of the two installation grooves.

[0012] In one example, a switch panel is fixedly arranged on one side of the box body, and the motor, the electric heating wires and the blower are all electrically connected to an external power supply through the switch panel.

[0013] The electric heating constant temperature blast drying box proposed by the present utility model can bring the following beneficial effects:

[0014] For the electric heating constant temperature blast drying box, by setting the support mechanism, the support mechanism is adjusted according to the shape of the dried material. When drying large-volume materials, the scraper is stored in the storage groove, so that when the motor drives the rotating shaft to drive the placing tray to rotate, the large-volume materials rotate with the placing tray and are heated evenly. When drying granular materials, they will stack on each other in the placing tray. The scraper is rotated down. When the placing tray rotates, the scraper will continuously stir the materials therein to make them turn over, so that the small-particle materials can be turned over in time, and the phenomenon that the stacked and squeezed areas cannot be dried is not likely to occur, improving the drying effect of the device.

Specific embodiments

[0022] In order to more clearly illustrate the overall concept of the present utility model, the following is a detailed description by way of example in conjunction with the specification drawings.

[0023] The embodiments are as follows:

[0024] The present utility model provides an electrothermal constant-temperature blast drying oven as shown in Figures 1-5 Figure, which includes a box body 1 and a support mechanism 2 installed inside the box body 1;

[0025] The support mechanism 2 includes a mounting backing plate 201 fixed to one side of the inner wall of the box body 1. Three support frames 202 are equidistantly fixed on one side of the mounting backing plate 201. A sleeve 203 is fixed to one end of each of the three support frames 202. A storage groove 204 is opened at the lower end of one side of each sleeve 203. A scraping plate 205 is rotatably provided at the lower end of the inner wall of each storage groove 204. A rotating shaft 206 is rotatably provided at the middle position of the inner wall of the box body 1, and the outer wall of the rotating shaft 206 is respectively inserted and connected with the inner walls of the three sleeves 203. The outer wall of the rotating shaft 206 is equidistantly fixed with storage trays 207. A through hole 208 is opened at the top of each storage tray 207. One end of the rotating shaft 206 passes through the top of the box body 1 and is connected with a motor 209. Each storage tray 207 is connected between two adjacent sleeves 203 through the rotating shaft 206 and rotates without being hindered by the sleeve 203, and can rotate 360 degrees to fully change the positions of each material in the storage tray 207. Moreover, the scraping plate 205 rotates in the storage groove 204 with a certain resistance and cannot rotate by itself without manual operation. And the sleeve 203 is connected and fixed inside the box body 1 through the mounting backing plate 201 and the support frame 202. The top of the uppermost sleeve 203 is fixed to the inner wall of the box body 1;

[0026] Further, a sealing cover 3 is hinged to one side of the inner wall of the box body 1, and mounting grooves 4 are opened on both sides of the inner wall of the box body 1.

[0027] The inner walls of the two installation grooves 4 are both installed with a plurality of electric heating wires 5, and a blower 6 is installed at the lower edge of the back of the box body 1. After starting the electric heating wires 5, the blower 6 is started to make the hot air flow circulate in the box body 1 to accelerate the drying of the material;

[0028] Furthermore, a groove 7 is provided on one side of the top of the box body 1, and a plurality of exhaust grooves 8 are provided at equal distances at the bottom of the inner wall of the groove 7, and the inner wall of each exhaust groove 8 is connected to the inner wall of the box body 1. During the drying process, the sealing plate 9 can be pulled out to open the exhaust grooves 8 at the bottom of the groove 7, so that the water vapor generated in the box body 1 can be discharged, thereby improving the drying efficiency.

[0029] A sealing plate 9 is inserted at the upper edge of one side of the box body 1, and the outer wall of the sealing plate 9 is inserted and connected with the inner wall of the groove 7. A plurality of heat dissipation holes 10 are evenly spaced on both sides of the inner wall of the box body 1, and the inner wall of each heat dissipation hole 10 is respectively connected with the inner walls of the two mounting grooves 4. The high temperature generated by the electric heating wire 5 is slowly discharged through the heat dissipation hole 10 and enters the box body 1, which can ensure the temperature inside the box body 1 while preventing the material from melting due to excessive temperature.

[0030] Working principle: When using the electric constant temperature blast drying oven in this design, firstly, the material needs to be placed on the storage tray 207, the sealing cover 3 is closed, and the electric heating wire 5 and the blower 6 are started at the same time to circulate the heated air in the box body 1, so as to quickly dry the material on the storage tray 207. If the material on the storage tray 207 is granular and the quantity is large, before placing the material, the scraper 205 in the receiving groove 204 on one side of each sleeve 203 is rotated to make it fit on the bottom of the inner wall of the storage tray 207, and then the material is dried. During the drying process, the disk 207 is driven by the motor 209 to rotate the rotating shaft 206 and then drives the placement disk 207 to rotate between two adjacent sleeves 203. While rotating, the scraper 205 scrapes the granular material on the disk to flip it over, so that the material is fully dried, and the stacked extrusion surface is not prone to being unable to dry. When drying block materials, the scraper 205 is stored in the storage groove 204 so that the rotating placement disk 207 does not block the material, so that the drying box can fully dry the material when drying block and granular materials, thereby improving the drying effect of the device.

In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0032] The above are only embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
