Description

Technical Field

[0001] This utility model relates to the field of gypsum board production equipment, and in particular to an energy-saving calcining furnace for gypsum board. Background Technology

[0002] Gypsum board is a material made primarily from building gypsum. It is a lightweight, high-strength, thin, easy-to-process building material with good sound insulation, heat insulation, and fire resistance properties. It is one of the new lightweight building materials that is currently being developed. After gypsum board is formed, it needs to be heated, dried, and fired. During the firing process, it is necessary to ensure uniform heating to prevent cracking, and dry particles will be produced on the surface.

[0003] A search revealed that Chinese Patent Publication No. CN214842302U discloses a double-sided drying device for gypsum board production. This patent includes a power frame, a support column at the bottom of the power frame, a movable shaft on one side of the power frame, a conveying roller outside the movable shaft, and a heating box at the top of the power frame. The limiting plate is connected and installed by a fixing plate to prevent the gypsum board from tipping over after entering the drying device, thus affecting the drying efficiency. The input end of the power frame is electrically connected to the output end of an external power source to drive the movable shaft to rotate, causing the auxiliary roller to rotate and facilitating the conveying of the gypsum board into the drying device for drying. The device uses hot air generated by heating wires to flow between two symmetrically arranged heating chambers. When the gypsum board enters the drying device vertically, both sides of the gypsum board can be dried simultaneously. However, compared with existing technologies, this device cannot guarantee uniform heating of the perimeter and the center when the gypsum is calcined and dried on both sides simultaneously. This leads to uneven temperature distribution and cracking of the gypsum, and the dried particles formed during calcination are difficult to remove in time, affecting the calcination effect. The practicality needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide an energy-saving calcining furnace for gypsum board in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An energy-saving calcining furnace for gypsum board includes a furnace body with a set of guide rails fixedly connected inside. Sealing doors are rotatably connected to both ends of the furnace body. A heating mechanism is provided on the side of the furnace body. Two symmetrically arranged air guiding mechanisms are provided inside the furnace body. A conveying mechanism is installed on the guide rails. The conveying mechanism includes two movable seats, with a connecting shaft rotatably connected to each movable seat. A limit frame is fixedly connected to the connecting shaft, and a rotating shaft is rotatably connected to the limit frame. A connecting rod is fixedly connected to the rotating shaft, and a pressing component is provided on the connecting rod. The pressing component pushes the connecting rod, thereby raising the limit frame and ensuring uniform heating of the gypsum board. Two symmetrically arranged limiting mechanisms are provided inside the furnace body. A power component is installed in one of the movable seats. The limiting mechanism includes a limiting block, which is thicker in the middle and thinner at both ends, with a sliding groove in the middle of the limiting block.

[0007] Preferably, the extrusion assembly includes an extrusion shaft, which is rotatably connected to the end of the connecting rod away from the movable seat. A sliding plate is fixedly connected to the end of the connecting rod away from the extrusion shaft, and a pulley is rotatably connected to the sliding plate. The pulley is disposed in a groove.

[0008] Preferably, the air guiding mechanism includes an air guiding plate, which is V-shaped in general. The air guiding plate has several air guiding holes, and a collection groove is provided on the bottom side of the air guiding plate.

[0009] Preferably, the limiting block has inclined surfaces at both the top and bottom ends.

[0010] Preferably, the heating mechanism includes a hot air blower, the outlet of the hot air blower is connected to a dryer through a pipe, two air ducts are fixedly connected to the dryer, a uniform air distribution plate is fixedly connected to the end of the air duct away from the dryer, and a hot air nozzle is fixedly connected to the uniform air distribution plate.

[0011] Preferably, the power component includes an electric motor, which is fixedly connected inside the movable base. A turntable is fixedly connected to the output end of the electric motor, and the outer circumferential surface of the turntable abuts against the guide rail and is provided with an anti-slip layer.

[0012] The beneficial effects are as follows: The system is equipped with an air guiding mechanism, a conveying mechanism, and a limiting mechanism. The gypsum board is placed on the limiting frame, and the entire moving seat is moved by the turntable. As the gypsum board moves with the moving seat, the sliding groove on the limiting block causes the extrusion component to push the limiting frame up, making the gypsum board heat more evenly and allowing the particles formed by drying and calcination to fall into the collection tank, which greatly improves the calcination effect of the gypsum board.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1 — Figure 6 As shown, an energy-saving calcining furnace for gypsum board includes a furnace body 101. A set of guide rails 102 are bolted inside the furnace body 101. Sealing doors 103 are rotatably connected to both ends of the furnace body 101. A heating mechanism is provided on the side of the furnace body 101. Two symmetrically arranged air guide mechanisms are provided inside the furnace body 101. A conveying mechanism is mounted on the guide rails 102. The conveying mechanism includes two movable seats 401, which are slidably connected to the guide rails 102. A connecting shaft 402 is rotatably connected to the movable seats 401. A limit frame 403 is bolted to the connecting shaft 402. A rotating shaft 404 is rotatably connected to the limit frame 403. A connecting rod 405 is welded to the rotating shaft 404. A pressing assembly is provided on the connecting rod 405. The pressing assembly is used to push the connecting rod 405, thereby moving the limit frame 405. 03. Lifting the plasterboard ensures even heating. Before lifting the plasterboard, hot air blows directly onto it to preheat the upper and lower surfaces, preventing the heating rate at the edges from exceeding that in the center. When lifting the plasterboard, hot air blows from the top and bottom towards it, ensuring more even heating on both sides and allowing the calcined and dried particles formed on the surface to fall off naturally. The furnace body 101 contains two symmetrical limiting mechanisms, and a power assembly is installed in a moving seat 401. The limiting mechanism includes a limiting block 501, which is thicker in the middle and thinner at both ends. A groove 503 is provided in the middle of the limiting block 501. The limiting block 501 causes the extrusion assembly to be squeezed by the groove 503, pushing the limiting frame 403 to lift and guiding the hot air towards the center.

[0026] In this embodiment, the extrusion assembly includes an extrusion shaft 406, which is rotatably connected to the end of the connecting rod 405 away from the movable seat 401. The end of the connecting rod 405 away from the extrusion shaft 406 is bolted to a sliding plate 407, and a pulley 408 is rotatably connected to the sliding plate 407. The pulley 408 is disposed in the slide groove 503.

[0027] In this embodiment, the air guiding mechanism includes an air guiding plate 301, which is V-shaped. The V-shaped air guiding plate 301 allows the heat supplied by the heating mechanism to be preferentially supplied to the middle part of the furnace body 101, thereby improving the calcination efficiency. The air guiding plate 301 has several air guiding holes 302, and the bottom side of the air guiding plate 301 has a collection groove 303. The dry particles formed by the calcination of gypsum board will fall into the collection groove 303. During use, the staff will clean the collection groove 303 regularly.

[0028] In this embodiment, the limiting block 501 is provided with inclined surfaces 502 at both the upper and lower ends. The inclined surfaces 502 facilitate the direct blowing of hot air onto the gypsum board, thereby improving the calcination effect of the gypsum board.

[0029] In this embodiment, the heating mechanism includes a hot air blower 201. The outlet of the hot air blower 201 is connected to a dryer 202 via a pipe. Two air ducts 203 are bolted to the dryer 202. The end of the air duct 203 away from the dryer 202 is bolted to a uniform air distribution plate 204. A hot air nozzle 205 is bolted to the uniform air distribution plate 204. The uniform air distribution plate 204 is designed to ensure that heat is evenly supplied to the hot air nozzle 205 in the front-back direction.

[0030] In this embodiment, the power component includes an electric motor 409, which is bolted to the movable seat 401. The output end of the electric motor 409 is bolted to a turntable 410. The outer circumferential surface of the turntable 410 abuts against the guide rail 102 and is provided with an anti-slip layer. The electric motor 409 drives the turntable 410 to rotate. The turntable 410 moves the movable seat 401 as a whole through friction with the guide rail 102, thereby realizing the transportation function.

[0031] Working principle: When using this device, the closed door 103 at the entrance is opened, and a pair of gypsum boards to be calcined are placed on the limiting frame 403. The motor 409 and the hot air blower 201 are started. The hot air blower 201 delivers heat to the air distribution plate 204 after drying in the dryer 202, through the air duct 203. The heat is then sprayed out through several hot air nozzles 205 on the air distribution plate 204, guided evenly by the air guide plate 301 and sprayed out from the air guide holes 302. The heat flows towards the center through the inclined surfaces 502 on both sides of the limiting block 501, achieving a calcination and drying effect on the gypsum boards. The motor 409 drives the turntable 410 to rotate slowly, pushing the moving seat 401 to move on the guide rail 102. The moving seat 401 is connected to the guide rail 102 via the connecting shaft 402. The limiting frame 403 moves the gypsum board. As the limiting frame 403 moves to the middle of the furnace body 101, the pulley 408 is squeezed by the limiting block 501 and moves towards the moving seat 401. The pulley 408 pushes the sliding plate 407, the sliding plate 407 pushes the extrusion shaft 406, the extrusion shaft 406 lifts the connecting rod 405, and the connecting rod 405 lifts the limiting frame 403 through the rotating shaft 404, so that the gypsum board is heated more evenly in the direction of the hot air, and the calcination effect is better. As the gypsum board is lifted, the dry particles formed by calcination will fall from the middle of the guide rail 102 into the collection tank 303. When the gypsum board moves to the closed door 103 on the other side of the furnace body 101, the closed door 103 is opened, the calcined gypsum board is taken out, and the calcination operation of a set of gypsum boards is completed.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
