Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a novel electric heating blast drying box. Background Art

[0002] The electric heating blast drying oven uses electric heating to blast air circulation to dry the items. It is divided into blast drying and vacuum drying. Among them, blast drying is to blow hot air through a circulating fan to ensure the temperature balance in the box, and vacuum drying is to use a vacuum pump to extract the air in the box to make the atmospheric pressure in the box lower than normal pressure, so that the product can be tested in a very clean state. It is a commonly used instrument and equipment, mainly used to dry samples.

[0003] In the production process of microalgae nutrient solution, a blast drying oven is often used to dry samples, so as to facilitate subsequent tests, etc. In the prior art drying oven, multiple placement plates are fixed or flexibly arranged inside, and the spacing between the placement plates is adjusted to accommodate samples of various sizes within a certain range. However, due to the narrow space inside the drying oven, it is inconvenient to put in and take out samples. In order to change the current situation, a new type of electric blast drying oven is designed. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] Reference Figure 1-4A new type of electric hot air drying box includes a box body 1, a cover plate 2 and a placement plate 8. Two fixing plates 3 are fixedly provided on the outer walls of both sides of the box body 1. A screw 4 is rotatably provided between the two fixing plates 3. A driving motor 10 connected to the screw 4 is installed on one of the fixing plates 3. The two screws 4 are connected through a transmission mechanism. A nut 13 is threadedly sleeved on the screw 4 through a limiting mechanism. The nut 13 is connected to the cover plate 2 through a connecting mechanism. A mounting groove 7 is provided on the cover plate 2. An extrusion groove 16 is provided on the outer wall of the placement plate 8 in the mounting groove 7. A positioning block 17 is provided in the extrusion groove 16 through an extrusion mechanism. A positioning hole 9 corresponding to the positioning block 17 is provided on the outer wall of the cover plate 2.

[0022] The transmission mechanism includes a pulley 11 arranged on the screw rod 4. The two pulleys 11 are connected by a belt 12. The pulley 11 and the belt 12 can make the two screw rods 4 rotate synchronously, thereby realizing power transmission of the drive motor 10.

[0023] The limiting mechanism includes a limiting block 14 arranged on the nut 13. A limiting groove 15 corresponding to the limiting block 14 is arranged on the outer wall of the box body 1. The limiting block 14 is located in the limiting groove 15, which can prevent the nut 13 from rotating with the screw rod 4, thereby playing a limiting role.

[0024] The connecting mechanism includes a movable groove 6 arranged on the outer wall of the cover plate 2 and the nut 13, a connecting rod 5 is provided between the two movable grooves 6, and a drag spring is elastically connected between the outer wall of the connecting rod 5 and the inner wall of the movable groove 6. The drag spring can drag the connecting rod 5 to ensure that the other end of the connecting rod 5 is in the movable groove 6 on the outer wall of the nut 13, thereby realizing a stable connection of the cover plate 2 relative to the nut 13.

[0025] The extrusion mechanism includes an extrusion spring 18 arranged in the extrusion groove 16, and the two ends of the extrusion spring 18 are elastically connected to the outer wall of the positioning block 17 and the inner wall of the extrusion groove 16 respectively. The extrusion spring 18 realizes the extrusion operation of the positioning block 17, and can squeeze it into the positioning hole 9 to achieve stable installation of the placement plate 8 relative to the cover plate 2.

[0026] The connecting rod 5 is U-shaped in a top view, and the mounting groove 7 and the portion of the placement plate 8 in the mounting groove 7 are both T-shaped in a top view, as shown in the accompanying drawings for details.

[0027] When the utility model is used, the samples that need to be dried are placed in layers on the placement plate 8, and then the driving motor 10 is started. The driving motor 10 directly drives the screw 4 connected thereto to rotate, and the screw 4 cooperates with the pulley 11 and the belt 12 to drive another screw 4 to rotate. When the two screws 4 rotate synchronously, the nut 13 on the outer wall cooperates with the connecting rod 5 to drive the cover plate 2 and the placement plate 8 to move, so that the placement plate 8 with the samples is moved into the box body 1, and then the circulating fan blows out hot air into the box body 1 to realize the drying of the samples. After the drying is completed, the driving motor 10 is reversed to move the placement plate 8 with the oil-released samples out, and then the multiple layers of samples can be taken out from the side in sequence.

[0028] At this time, samples can only be taken out from both sides of the box body 1. At this time, drag the connecting rod 5 to stretch the drag spring, and the other end of the connecting rod 5 is disengaged from the movable groove 6 on the outer wall of the nut 13. Then the cover plate 2 and the placement plate 8 and other components can be completely separated from the box body 1. It will be very easy to take out the dry sample in an open area on one side. Similarly, the same operation can be applied when placing the sample.

[0029] In this scheme, five placement plates 8 are installed on the cover plate 2, and the distance between adjacent placement plates 8 is small. If the sample is large at this time, it is not necessary to install five placement plates 8. Only one, three, five or three placement plates 8 need to be installed from top to bottom. The installation steps of the placement plates 8 are: press the positioning block 17 to make it enter the extrusion groove 16, and then the T-shaped part of the placement plate 8 vertically enters the installation groove 7 and moves. When the positioning block 17 corresponds to the positioning hole 9, the extrusion spring 18 squeezes it into the positioning hole 9, and then the fixed and stable installation of the placement plate 8 relative to the cover plate 2 is completed.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
