[0020] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] See also Figure 1 The present invention provides the following technical solutions: an environmentally friendly heating furnace, comprising a furnace body 1, a furnace mouth 101 arranged on one side of the furnace body 1, support plates 2 fixed on both sides of the furnace mouth 101, and a furnace door 3 movably connected to the support plates 2. A heating mechanism is arranged in the furnace body 1, and two support plates 2 are arranged vertically and in parallel. The furnace door 3 comprises a frame 310 movably connected to the support plates 2 and a door body 320 arranged on one side of the frame 310. A positioning member 4 cooperating with the furnace door 3 is arranged at the furnace mouth 101. In this embodiment, the positioning member 4 is fixed. A positioning block is fixed at the lower part of the outside of the furnace opening 101. When the furnace door 3 moves downward and the furnace door 3 is just corresponding to the furnace opening 101, the furnace door 3 contacts the positioning block to prevent the furnace door 3 from moving downward. The support plate 2 is provided with a guide groove 5 for guiding the furnace door 3 to enter the inside of the furnace opening 101. The frame 310 is movably matched with the guide groove 5. The support plate 2 is also provided with a power mechanism 6 that is transmission-connected with the furnace door 3 and drives it to move along the guide groove 5. A temperature-sensing locking mechanism 7 that cooperates with each other is provided between the upper part of the furnace door 3 and the inner wall of the furnace opening 101.

[0022] The power mechanism 6 drives the furnace door 3 to move along the guide groove 5, so that the furnace door 3 can complete the vertical movement and enter the furnace opening 101, and cooperate with the furnace opening 101 to complete the sealing effect. The power mechanism 6 can keep the position of the furnace door 3 fixed, so that there is a good sealing effect between the furnace door 3 and the furnace opening 101;

[0023] When the temperature in the furnace rises, the temperature-sensitive locking mechanism 7 is activated, so that the furnace door 3 and the furnace opening 101 are locked, and the furnace door 3 cannot be opened. At the same time, the furnace door 3 and the furnace opening 101 are more closely matched, thereby improving the sealing effect;

[0024] Specifically, the temperature-sensitive locking mechanism 7 includes a locking groove 710 provided on the inner wall of the furnace opening 101, a temperature-sensitive action component 720 provided on the door body 320, and a locking block 730 connected to the temperature-sensitive action component 720;

[0025] In order to facilitate the temperature sensing action component 720 to generate an action according to the temperature change in the furnace, such as Figure 2 As shown, in a further embodiment, the temperature sensing action component 720 includes a cavity 721 disposed inside the door body 320 and containing a heat-sensitive medium, a first piston hole 722 connected to the cavity 721 and disposed perpendicularly to the entry direction of the furnace port 101, and a heat-conducting block 723 disposed on the inner side of the door body 320. In this embodiment, a plurality of first piston holes 722 are provided, and are evenly distributed along the circumference of the door body 320. A first piston rod 724 extending into the cavity 721 is provided in the first piston hole 722, and the locking block 730 is provided at the end of the first piston rod 724. The heat-conducting block 723 extends into the cavity 721.

[0026] After the furnace door 3 enters the furnace opening 101, when the temperature in the furnace rises, the heat conducting block 723 transfers heat to the heat-sensitive medium, and the heat-sensitive medium expands due to the heat. When the temperature reaches a certain threshold, the first piston rod 724 moves in the first piston hole 722 and drives the locking block 730 to enter the locking groove 710, completing the locking work;

[0027] In order to facilitate the adjustment of the temperature sensitivity, in a further embodiment, the side of the cavity 721 away from the heat-conducting block 723 is connected to a second piston hole 725, and the side of the door body 320 away from the heat-conducting block 723 is provided with a telescopic member 726, and the telescopic member 726 is connected to a second piston rod 727 extending into the second piston hole 725;

[0028] The telescopic member 726 drives the second piston rod 727 to move, so as to change the accommodation volume of the cavity 721, thereby changing the initial position of the first piston rod 724. After the change, when the temperature reaches different thresholds, the locking block 730 will enter the locking groove 710;

[0029] In order to ensure a better sealing effect between the furnace door 3 and the furnace opening 101 after the locking work is completed, in a further embodiment, the locking groove 710 is provided with an inclined first contact surface 711 on one side close to the furnace opening 101, and the locking block 730 is provided with an inclined second contact surface 731 on one side close to the furnace opening 101;

[0030] When the locking block 730 enters the locking groove 710, the first contact surface 711 cooperates with the second contact surface 731, so that the door body 320 moves inward, so that the door body 320 and the furnace opening 101 are further interference-fitted, thereby improving the sealing effect;

[0031] Specifically, Figure 3 As shown, the surface of the door body 320 is provided with an annular first sealing surface 321, the locking groove 710 is provided with a second sealing surface 712 located on the opposite side of the first contact surface 711, and a sealing ring 713 extending along the second sealing surface 712 is fixedly provided on the inner wall of the furnace opening 101;

[0032] When the door body 320 moves inward, the first sealing surface 321 and the second sealing surface 712 are interference-fitted to improve the sealing effect;

[0033] In order to facilitate the furnace door 3 to have a larger opening degree, in a further embodiment, as Figure 2 As shown, each support plate 2 is provided with two groups of identical guide grooves 5, and two guide blocks 311 are respectively provided on both sides of the frame body 310, and the two guide blocks 311 are respectively slidably matched with the two guide grooves 5 on the same side, and the guide groove 5 includes a vertical movable portion 501, a tightening portion 502 connected to the bottom of the movable portion 501 and inclined inwardly, and a positioning portion 503 connected to the bottom of the tightening portion 502 and inclined outwardly and interference-fitted with the guide block 311;

[0034] In this embodiment, the power mechanism 6 includes a bearing rod fixed to the support plate 2 and arranged horizontally, a mounting seat is rotatably connected to the bearing rod, a telescopic cylinder is fixed to the mounting seat, and a telescopic rod of the telescopic cylinder is rotatably connected to the frame 310;

[0035] Specifically, the frame body 310 includes a tightening seat 312 and a sliding seat 313. The tightening seat 312 is provided with a receiving hole 314 on one side close to the door body 320. The door body 320 is located in the receiving hole 314 and is connected to the bottom of the hole through a first elastic member 315. The sliding seat 313 is provided with a vertical slide groove 316 on one side close to the tightening seat 312. The top and bottom of the tightening seat 312 are connected to the slide groove 316 through a second elastic member 317. In this embodiment, the first elastic member 315 and the second elastic member 317 are both rigid springs.

[0036] Under the action of the guide block 311 and the guide groove 5, the frame 310 moves through the power mechanism 6, and the door 320 first moves along the movable part 501 with the frame 310. When the guide block 311 moves to the bottom end of the movable part 501, the door 320 conflicts with the positioning member 4.

[0037] When the sliding seat 313 continues to move along the tightening portion 502, the door body 320 will not move downward, so that the tightening seat 312 will not move downward. The frame body 310 will overcome the force of the second elastic member 317 and drive the tightening seat 312 to move toward the furnace opening 101. The tightening seat 312 pushes the door body 320 into the furnace opening 101 through the first elastic member 315 to cooperate with it. When the guide block 311 moves to the bottom end of the tightening portion 502, the door body 320 is matched with the furnace opening 101.

[0038] The sliding seat 313 continues to move to the positioning portion 503 and then stops. At this time, under the cooperation of the positioning portion 503 and the guide block 311, the furnace door 3 cannot move outward, and under the action of the power mechanism 6 and the second elastic member 317, the furnace door 3 is restricted from moving upward, thereby ensuring the stability and sealing of the furnace door 3.

[0039] In order to improve the stability of the sliding seat 313 when it cooperates with the tightening seat 312, in a further embodiment, a vertical guide member 318 is also provided between the tightening seat 312 and the sliding seat 313. The vertical guide member 318 includes guide holes arranged at the bottom and top of the slide groove 316, and a guide rod fixedly connected to the tightening seat 312. The guide rod extends into the guide hole and is connected to the tightening seat 312 through a second elastic member 317.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
