Description

Technical Field

[0001] The utility model relates to the technical field of roasting and heating, in particular to a heating structure of a roasting furnace for stacking production. Background Art

[0002] A roasting furnace is a device that performs high-temperature heating on powdered or granular materials. Traditional roasting furnaces are vertical structures. If preheating is not performed during the roasting process, the energy consumption required for direct combustion is relatively large, and incomplete combustion will occur during combustion.

[0003] Based on the above problems, the existing patent with publication number CN209131388U discloses a roasting furnace heating structure. The roasting furnace is divided into an upper furnace body and a lower furnace body by a partition, thereby reducing the height of the roasting furnace. When feeding sand into the roasting furnace, the waste sand will first fall into the upper furnace body, and the burner is installed on the side wall of the upper furnace body at a certain angle, which increases the area where the gas flame generated by the burner directly heats the waste sand, thereby improving the heating efficiency.

[0004] However, when implementing the above-mentioned roasting furnace heating structure, it was found that it still has at least the following problems: during the roasting process, it is often necessary to transport materials into the roasting furnace along the sand inlet on the furnace cover, and after the transportation is completed, the sand inlet needs to be closed to maintain the temperature in the roasting furnace and prevent the discharge of toxic gases due to insufficient roasting. However, during the roasting process, the closure that seals the sand inlet often has a higher temperature after a long period of roasting, and when it is opened, due to the high air pressure in the roasting furnace, the hot air flow in the roasting furnace is quickly discharged outward along the sand inlet in the form of an eruption, which also makes it more troublesome to open the closure from the sand inlet, and after opening, it may also cause certain injuries to the roasting workers.

[0012] Compared with the prior art, the utility model provides a heating structure of a roasting furnace for stacking production, which has the following beneficial effects:

[0013] The utility model uses an electric push rod to push the moving block to move back and forth, thereby driving the sliding rod to slide in the guide rail one, and the moving rod one and the moving rod two are driven by the sliding rod to move the furnace cover toward the feeding port, and through the downward moving groove, the furnace cover can be moved up and down at the feeding port when it is located, so as to cover or open the furnace cover.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figures 1 to 5According to an embodiment of the utility model, a technical solution is provided: a heating structure of a roasting furnace for stacking production, comprising a furnace body 1 and a burner body 2 fixed on both sides of the furnace body 1, a feed port 3 is provided on the furnace body 1, a furnace cover 4 is provided on both sides of the furnace cover 4, a guide rail 1 5 and a guide rail 2 6 fixed on the furnace body 1 are provided, a moving block 7 is provided between the two guide rails 1 5, a side of the moving block 7 away from the feed port 3 is fixed to an electric push rod 8 fixed on the furnace body 1, sliding rods 9 slidably connected to the guide rail 1 5 are fixed at both ends of the moving block 7, moving rods 10 and moving rods 11 are rotatably connected at both ends of the sliding rod 9, the moving rods 10 and 11 are both rotatably connected to the furnace cover 4, a limiting rod 12 facing the guide rail 2 6 is fixed at the rotation connection between the moving rod 2 11 and the furnace cover 4, and a downward displacement groove 13 for the limiting rod 12 to slide is provided on the guide rail 2 6.

[0024] The heating structure of the roasting furnace for stacking production using the above structure is adopted. The electric push rod 8 pushes the moving block 7, which in turn drives the sliding rod 9 to slide in the guide rail 1 5, and the moving rod 1 10 and the moving rod 2 11 are driven by the sliding rod 9 to move the furnace cover 4 toward the feeding port 3. When the furnace cover 4 moves to above the feeding port 3, the limiting rod 12 on the moving rod 2 11 falls into the lower moving groove 13, and then the furnace cover 4 covers the feeding port 3. When the furnace cover 4 needs to be opened, the electric push rod 8 pulls the moving block 7, and the moving rod 2 11 is affected by the limiting rod 12. , the moving rod 2 11 is tilted together with the moving rod 1 10 and drives the furnace cover 4 to move upward along the downward groove 13 until the limit rod 12 leaves the downward groove 13. At this time, the furnace cover 4 is located directly above the feeding port 3. Then the electric push rod 8 is continuously pulled to move the furnace cover 4 from directly above the feeding port 3 toward the direction of the electric push rod 8. This structure can realize opening or closing of the furnace cover 4 by pushing and pulling the electric push rod 8. No manual opening and closing is required, which effectively prevents the furnace cover 4 from being opened and closed at a higher temperature due to manual opening, and is easily scalded by the hot air in the furnace body 1 when opened.

[0025] In this embodiment, each sliding rod 9 is rotatably connected to the rotating connection between the moving rod 1 10 and the moving rod 2 11 with a pulley 14. By providing the pulley 14, the friction generated when the sliding rod 9 slides in the guide rail 1 5 is reduced.

[0026] In this embodiment, both limit rods 12 are rotatably connected with pulley 2 15, and the diameter of pulley 2 15 is adapted to the width of the downward groove 13. By setting pulley 2 15, the stability of the limit rod 12 sliding in guide rail 2 6 can be increased, and the diameter of pulley 2 15 is adapted to the width of the downward groove 13, which can ensure that the limit rod 12 will not be offset when the furnace cover 4 moves upward, thereby causing the problem that the furnace cover 4 cannot be moved out from the feed port 3.

[0027] In this embodiment, a heat insulating layer 16 is fixedly provided on the side of the furnace cover 4 facing the material feed port 3 . By providing the heat insulating layer 16 , the influence of the temperature in the furnace body 1 on the furnace cover 4 can be reduced.

[0028] In this embodiment, an asbestos layer 17 is further provided on the side of the furnace cover 4 facing the feed port 3, and the asbestos layer 17 wraps the heat insulation layer 16. By providing the asbestos layer 17, the flame or heat flow in the furnace body 1 can be reduced from baking the furnace cover 4 and causing damage to the furnace cover 4. The asbestos layer 17 has good burning resistance and heat insulation, which further reduces the influence of the temperature in the furnace body 1 on the furnace cover 4.

[0029] In this embodiment, a roller 18 is arranged between the two guide rails 6, and a rolling groove 19 for the roller 18 to roll is opened on the furnace body 1. The roller 18 arranged on the furnace body 1 can support the furnace cover 4 and reduce friction during the translation of the furnace cover 4, thereby preventing the furnace cover 4 from sliding on the furnace body 1 for a long time and causing wear on the contact surface between the furnace cover 4 and the furnace body 1.

[0030] Working principle: When the roasting furnace is needed, the material to be roasted is put into the furnace body 1 through the feed port 3, and the material to be roasted in the furnace body 1 is calcined through the burner body 2. After that, the furnace cover 4 needs to be closed to keep the temperature in the furnace body 1 stable. The moving block 7 can be pushed by the electric push rod 8, thereby driving the sliding rod 9 to slide in the guide rail 5, and the moving rod 10 and the moving rod 2 11 are driven by the sliding rod 9, thereby driving the furnace cover 4 on the fixed moving rod 10 and the moving rod 2 11 to move toward the feed port 3. During the movement, when the furnace cover 4 moves to above the feed port 3, the limiting rod 12 on the moving rod 2 11 and the pulley 2 15 rotatably connected to the limiting rod 12 fall along the downward groove 13 to the bottom of the downward groove 13, thereby driving the furnace cover 4 moves downward to close the furnace cover 4 on the feeding port 3. When the furnace cover 4 needs to be opened, the electric push rod 8 pulls the moving block 7. Due to the influence of the limiting rod 12, the moving rod 11 tilts together with the moving rod 10 and drives the furnace cover 4 to move upward along the downward groove 13 until the pulley 15 on the limiting rod 12 leaves the downward groove 13. At this time, the furnace cover 4 is located directly above the feeding port 3. Thereafter, the electric push rod 8 continues to pull to move the furnace cover 4 from directly above the feeding port 3 toward the electric push rod 8. When the furnace cover 4 is located on the furnace body 1 and translates, the roller 18 arranged on the furnace body 1 can support and reduce friction for the furnace cover 4 during the translation process of the furnace cover 4, thereby preventing the furnace cover 4 from sliding on the furnace body 1 for a long time and causing wear on the contact surface between the furnace cover 4 and the furnace body 1.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
