Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to a constant temperature controlled heating furnace. Background Art

[0002] A constant temperature controlled heating furnace is a special heating device that uses constant temperature control technology to keep the temperature inside the furnace constant within a certain range. Heating furnaces are widely used in many fields, such as laboratory research, chemical reaction control, medical equipment, food processing, packaging and printing, electronics manufacturing, and petrochemicals. In these fields, constant temperature controlled heating furnaces can provide stable and precise temperature control to meet the temperature requirements of different applications. They are efficient, precise, safe and reliable heating equipment.

[0003] After searching, the Chinese patent with announcement number CN207180351U discloses a constant temperature controlled heating furnace, which heats the workpiece through an electric heating furnace through an electric heating wire or an electric heating tube. However, the heating wire or the electric heating tube is easily damaged due to excessive temperature. At the same time, it is not easy to find the specific location of the damage to the heating wire or the electric heating tube, which is inconvenient for maintenance personnel to carry out repairs in time. This results in a large amount of manpower and material resources being required to replace the heating wire or the electric heating tube, and also makes the working efficiency of the heating furnace too low. Therefore, when the electric heating tube is damaged, the electromagnet cannot generate electromagnetic induction, and the iron pin is not subjected to magnetic force, so it is easy to remove the cover, then remove the silicon carbide ceramic plate, and replace the damaged electric heating tube. At the same time, because the indicator light is off, it is easy to find which electric heating tube is damaged.

[0004] During the use of the above-mentioned constant temperature controlled heating furnace, it is convenient to repair and replace the electric heating tube. However, in the prior art, the heating furnace is usually heated by a heating tube, and the heating tube is distributed in different positions of the heating furnace. When the heating tube heats up, high temperature will be generated around the heating furnace where the heating tube is installed, while the heating furnace far away from the side of the heating tube will hardly receive the heated temperature, resulting in slower temperature propagation during heating, making it easy for the heating furnace to produce uneven heating during heating, thereby reducing the heating efficiency.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] As attached Figure 1-6 As shown, the present invention provides an embodiment: a constant temperature controlled heating furnace, comprising a furnace body 1, with a heating component provided on the outside of the furnace body 1;

[0033] The heating assembly includes a plurality of mounting slots 2, which are opened on the outside of the furnace body 1, and a heating rod 3 is fixedly installed inside the mounting slot 2. The outside of the furnace body 1 is fixedly connected to an outer shell 4, and an insulation layer 5 is provided inside the outer shell 4. The inner wall of the outer shell 4 is fixedly connected to a guide plate 6, and one side of the outer shell 4 is fixedly connected to a mounting shell 7. A fan 8 is fixedly installed inside the mounting shell 7, and a dust barrier plate 9 is fixedly connected to the lower surface of the mounting shell 7. The upper surface of the mounting shell 7 is through-connected with a circulation pipe 10, and one end of the circulation pipe 10 is through-connected to the upper surface of the outer shell 4. A plurality of air outlet slots 11 are opened on the lower surface of the outer shell 4. The heating rod 3 facilitates the dissipation of heat, the wind force of the fan 8 facilitates the movement of heat, the guide plate 6 facilitates the guidance of the movement of heat, and the air outlet slots 11 facilitate the discharge of wind force, thereby forming a wind circulation.

[0034] As attached Figure 5 As shown, a discharging assembly is provided on the outside of the shell 4, and the discharging assembly includes two rope winding wheels 12, which are rotatably connected to both sides of the shell 4, and a high-temperature resistant rope 13 is provided inside the rope winding wheel 12. The high-temperature resistant rope 13 is made of glass fiber, and a storage plate 14 is provided at one end of the two high-temperature resistant ropes 13. One side of the rope winding wheel 12 is fixedly connected to a shaft rod 15, and one end of the shaft rod 15 is fixedly connected to a first bevel gear 16. One side of the shell 4 is rotatably connected to a connecting rod 17, and both ends of the connecting rod 17 are fixedly connected to a second bevel gear 18. The second bevel gear 18 is meshed with the first bevel gear 16, and one end of the connecting rod 17 is fixedly connected to a stepper motor 19. The stepper motor 19 is arranged on one side of one of the second bevel gears 18. The outside of the shell 4 is fixedly connected to a protective shell 20, and the rope winding wheel 12 facilitates the retraction and release of the high-temperature resistant rope 13, and the shaft rod 15 facilitates the connection between the first bevel gear 16 and the rope winding wheel 12, and the protective shell 20 facilitates the protection of the internal components.

[0035] As attached Figure 1 As shown, two protective covers 21 are fixedly connected to the upper surface of the shell 4, and an opening and closing cover 22 is hinged on the upper surface of the furnace body 1. The opening and closing cover 22 helps to reduce heat leakage.

[0036] Working principle: When in use, first put the material into the interior of the furnace body 1, then clamp the air heating rod 3, so that the heating rod 3 heats up and generates heat, and then turn on the fan 8. The fan 8 allows the air to enter through the dust blocking plate 9, so that the wind reaches the interior of the circulation pipe 10, and is then transported to the cavity between the outer shell 4 and the furnace body 1. Then, under the guidance of the guide plate 6, the wind takes away the heat when passing through the heating rod 3. The heat flows along the guide plate 6 to heat the furnace body 1 around, and then the air is discharged through the air outlet slot 11, forming a heat cycle, thereby improving the uniformity of heating of the furnace body 1;

[0037] After the material is heated, when it is necessary to discharge the material, the stepper motor 19 is turned on, so that the stepper motor 19 drives the connecting rod 17 to rotate. When the connecting rod 17 rotates, the second bevel gears 18 at both ends are driven to rotate. Through the engagement of the second bevel gear 18 with the first bevel gear 16, it is convenient to drive the first bevel gear 16 to rotate, thereby facilitating the rotation of the shaft 15, and the shaft 15 drives the rope pulley 12 to rotate, so that the rope pulley 12 can shrink the wound high-temperature resistant rope 13, so that the high-temperature resistant rope 13 can pull the storage plate 14 up, which helps to drive the material up, thereby facilitating the cooling and removal of the material. When the material is taken out, the reverse function of the stepper motor 19 is turned on to facilitate the release of the high-temperature resistant rope 13. Under the action of gravity, the storage plate 14 can fall and reset.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
