Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material drying, in particular to a hot air circulation oven. Background Art

[0002] The oven shell is generally made of thin steel plate with a paint finish on the surface, and the working room is made of high-quality structural steel plate. Aluminum silicate fiber is filled between the shell and the working room. The heater is installed at the bottom, and can also be placed on the top or both sides. The temperature control instrument uses a digital display smart meter. The existing hot air circulation oven for medicinal materials heats and dries by placing the medicinal materials on a tray and then placing the tray inside the oven.

[0003] Since the existing drying device spreads the medicinal materials flat on the surface of the tray, it is very easy to cause uneven heating of the medicinal materials. Therefore, the staff needs to manually turn them over regularly, which takes a lot of time and greatly reduces the drying efficiency. Therefore, we propose a hot air circulation oven to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A hot air circulation oven comprises a hot air circulation oven body 1 and a motor 6. A storage groove 2 is inserted into the inner bottom of the hot air circulation oven body 1. Support rods 10 are symmetrically fixedly connected to the inner sides of the hot air circulation oven body 1, and one end of the support rod 10 away from the inner wall of the hot air circulation oven body 1 is fixedly connected to a bearing sleeve 11. A filter barrel 3 is inserted into the bearing sleeve 11, and a filter tank 15 is inserted into the filter barrel 3. A protective cover plate 4 is fixedly connected to the surface of the filter tank 15. A second connecting rod 12 is fixedly connected to the back of the filter barrel 3, and a third connecting rod 13 is fixedly connected to the back of the second connecting rod 12. A transmission mechanism 5 is sleeved on the surface of the third connecting rod 13. The transmission mechanism 5 is composed of a synchronous belt and a synchronous pulley. The synchronous pulley is fixedly sleeved on the surface of the third connecting rod 13, and the synchronous belt is sleeved on the surface of the synchronous pulley to realize the transmission function. The output end of the motor 6 is fixedly connected to the third connecting rod 13, and the motor 6 is connected to the back of the hot air circulation oven body 1 through a support frame 7.

[0023] Further, see Figure 5 It can be known that the surface of the protective cover 4 is fixedly connected with the fifth connecting rod 20, and the top of the fifth connecting rod 20 is fixedly connected with the first connecting rod 9, and the top of the first connecting rod 9 is fixedly connected with the fourth connecting rod 19. The first connecting rod 9, the fourth connecting rod 19 and the fifth connecting rod 20 form a C-shaped structure, which facilitates the active connection between the protective cover 4 and the rectangular block 8 during use.

[0024] Further, see Figure 4 and Figure 5 It can be known that a rectangular block 8 is fixedly connected to the top of the filter barrel 3, and a rectangular groove is opened on the surface of the rectangular block 8, and a fourth connecting rod 19 is inserted into the inside of the rectangular groove, and the fourth connecting rod 19 is movably connected to the rectangular block 8.

[0025] Further, see Figure 3 and Figure 4 It can be seen that a rectangular groove is provided at the top of the rectangular block 8, a limiting groove is provided at the top of the fourth connecting rod 19, and a limiting pin 17 is inserted through the inside of the rectangular groove. During use, the limiting pin 17 facilitates the limiting function of the fourth connecting rod 19.

[0026] Further, see Figure 5 It can be seen that the top of the limit pin 17 is fixedly connected to a fixed plate 18, and the surface of the limit pin 17 is sleeved with a spring 16. During use, the limit pin 17 is easily reset by the spring 16, thereby facilitating repeated use.

[0027] Further, see Figure 4 It can be known that the limit bars 14 are symmetrically fixedly connected on both sides of the filter tank 15, and the inner walls on both sides of the filter barrel 3 are symmetrically provided with sliding grooves, and the limit bars 14 are inserted inside the sliding grooves. During use, the limit bars 14 can limit the filter tank 15 to facilitate linear movement.

[0028] Working principle: When the utility model is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 As shown, when the medicinal materials need to be dried, the staff manually pulls the first connecting rod 9 outward, and the first connecting rod 9 drives the fifth connecting rod 20 and the fourth connecting rod 19 to move outward at the same time, and the fifth connecting rod 20 drives the filter tank 15 to slide out of the interior of the filter barrel 3, and the fourth connecting rod 19 moves to contact the surface of the limit pin 17, so that the limit pin 17 is easy to move upward, and the spring 16 is in an expanded state. When the external force is released, the spring 16 drives the limit pin 17 to reset through its own contraction force;

[0029] At this time, the medicinal materials are put into the filter tank 15, and the protective cover plate 4 is pushed to move the filter tank 15 to the inside of the filter barrel 3. The movement of the protective cover plate 4 drives the first connecting rod 9 to move, and the movement of the first connecting rod 9 drives the fourth connecting rod 19 to move. The movement of the fourth connecting rod 19 conflicts with the bottom end surface of the limit pin 17, and the limit pin 17 is forced to move upward. The spring 16 is in an expanded state, and the fourth connecting rod 19 moves until a limit groove is opened on the surface corresponding to the limit pin 17. At this time, the external force of the spring 16 is released, and the spring 16 is reset to drive the limit pin 17 to be inserted into the limit groove opened on the surface of the fourth connecting rod 19, so as to facilitate the fixed limit function;

[0030] After the delivery is completed, the motor 6 is energized, and the output end of the motor 6 rotates to drive the third connecting rod 13 to rotate, and the third connecting rod 13 rotates simultaneously through the transmission mechanism 5. The rotation of the third connecting rod 13 drives the second connecting rod 12 to rotate, and the rotation of the second connecting rod 12 drives the filter barrel 3 to rotate, and the rotation of the filter barrel 3 drives the filter tank 15 to rotate, so as to facilitate the tumbling of the medicinal materials therein, thereby improving the drying efficiency, and the operation is completed. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.
