Description

Technical Field

[0001] The utility model relates to the technical field of drying furnaces, in particular to a drying furnace with a heating device that is easy to maintain. Background Art

[0002] A drying furnace is an industrial equipment, which is mainly used to remove moisture and humidity from the surface or inside of an object. There are many types of drying furnaces, among which the tunnel drying furnace is one of them. It has high flexibility and can adapt to different production needs by adjusting the temperature and furnace speed to meet the production process requirements of different products. Therefore, it is widely used in the fields of pharmaceuticals, food, chemicals, building materials, metallurgy, etc. During the use of the tunnel drying furnace, the staff needs to regularly maintain the heating device installed in the furnace cavity to ensure its subsequent drying effect on the object.

[0003] At present, in order to facilitate maintenance work, the existing tunnel drying furnace has a furnace cavity and a support table that are hingedly connected. When maintenance work is needed, the staff can flip the furnace cavity. After the furnace cavity is flipped, since the support table has a large width, the staff needs to lean forward as much as possible to contact the heating device during the maintenance process. Due to the large specifications of the furnace cavity, the maintenance time is relatively long, which makes the staff more time-consuming and laborious during the maintenance process. For this reason, we propose a drying furnace that is easy to maintain the heating device to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a drying furnace with a heating device that is easy to maintain.

DETAILED DESCRIPTION

[0022] 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.

[0023] Reference Figure 1-5 A drying furnace for convenient maintenance of a heating device comprises a support table 1, a furnace chamber 2 is arranged above the support table 1, the working principle of the support table 1 and the furnace chamber 2 is the prior art, and no further description is given here, a strip groove is provided on the back of the support table 1, and a U-shaped block 3 is distributed inside the strip groove, the inner wall of the U-shaped block 3 is connected with a connecting shaft 4, and a rotating block 5 is sleeved on the outer side of the connecting shaft 4, the side of the rotating block 5 is fixedly connected to the furnace chamber 2, the bottom end of the U-shaped block 3 is connected with a slider 6, and the rotating block 5 and the connecting shaft 4 are matched with each other. The support platform 1 is provided with a sliding groove 14 which is compatible with the support platform 1. Through the cooperation between the slider 6 and the sliding groove 14, the staff can push the furnace cavity 2 to the right as a whole for maintenance operations. The front side of the support platform 1 is provided with a buckle lock 7. The buckle lock 7 is a prior art. Through the setting of the buckle lock 7, the furnace cavity 2 can be limited to effectively prevent the furnace cavity 2 from moving easily during operation.

[0024] Further, see Figure 1 and Figure 2 It can be known that the side of the furnace chamber 2 is symmetrically connected with a fixing block 8, and a cylinder 9 is installed on the outside of the fixing block 8, and the other end of the cylinder 9 is connected to a support plate 10. The cylinder 9 is a prior art and will not be elaborated here. Through the mutual cooperation of the cylinder 9 and the support plate 10, the furnace chamber 2 pushed to the right can be supported to ensure the reliability of the device during use.

[0025] Further, see Figure 1 It can be known that a rubber plate is glued to the bottom end of the support plate 10, and anti-slip grooves are provided at the bottom end of the rubber plate. Through the mutual cooperation of the rubber plate and the anti-slip grooves, the friction between the bottom end of the support plate 10 and the ground can be effectively improved, thereby improving the supporting effect on the furnace cavity 2.

[0026] Further, see Figure 3 and Figure 5It can be known that a groove is provided on the inner wall of the furnace cavity 2, and a limit plate 12 is engaged inside the groove. A threaded rod 11 is connected to one side of the limit plate 12 through a bearing, and the threaded rod 11 extends to the outside of the furnace cavity 2. A threaded groove matching the threaded rod 11 is provided inside the furnace cavity 2, and a limit groove matching the limit plate 12 is provided inside the connecting shaft 4. After the furnace cavity 2 is turned over, the limit plate 12 is able to correspond to the position of the limit groove provided inside the connecting shaft 4. At this time, the staff can rotate the threaded rod 11, so that the limit plate 12 can be pushed inward into the limit groove provided inside the connecting shaft 4 to achieve the limitation of the furnace cavity 2, so as to prevent the staff from accidentally touching the furnace cavity 2 during maintenance, thereby causing the furnace cavity 2 to rotate easily, so as to effectively ensure the safety of the device when in use.

[0027] Further, see Figure 2 It can be seen that the end of the threaded rod 11 is connected to a rotary block 13, and the outer surface of the rotary block 13 is evenly distributed with anti-skid particles. When in use, the rotary block 13 and the anti-skid particles cooperate with each other to facilitate the staff to rotate the threaded rod 11.

[0028] Further, see Figure 2 It can be known that the top end of the support plate 10 is connected to a threaded sleeve 15, and the end of the cylinder 9 is provided with an external thread that is compatible with the threaded sleeve 15. The external threads set on the threaded sleeve 15 and the end of the cylinder 9 can facilitate the staff to quickly disassemble the damaged support plate 10 and replace it.

[0029] Further, see Figure 4 It can be known that grooves are evenly formed at the bottom of the slider 6, and balls are installed inside the grooves. The multiple sets of balls arranged at the bottom of the slider 6 can save workers effort when pushing the furnace chamber 2.

[0030] Working principle: When the utility model is in use, the staff can first place the material to be dried on the conveyor belt of the support platform 1, and then start the work of the motor inside the support platform 1, so that the material can be conveyed to the bottom of the furnace cavity 2, and with the heating device arranged inside the furnace cavity 2, the material can be dried. After a period of use, when the staff needs to maintain and service the heating device inside the furnace cavity 2, the staff can first unlock the two sets of buckle locks 7 to release the restraint on the furnace cavity 2, and then the staff can flip the furnace cavity 2 as a whole, so that it drives the rotating block 5 to slide along the outer surface of the connecting shaft 4. After completing the flipping work, the staff can push the furnace cavity 2 to the right, so that the slider 6 connected to the bottom end of the U-shaped block 3 is forced to slide along the inner wall of the slide groove 14. When the slider 6 moves to abut the right inner wall of the slide groove 14, the staff can start the work of the two sets of cylinders 9, so that the support plate 10 is pushed and in contact with the ground to achieve the support work of the furnace cavity 2, and then the staff can move to the front side of the furnace cavity 2 for maintenance work. 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.

[0032] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
