Technical Field

[0001] The utility model relates to the technical field of heating furnaces, and particularly relates to a modular furnace body. Background Art

[0002] In the industrial implementation of tubular kilns, the usual structure is to directly build on the foundation of the industrial production site, use refractory material blocks to build the kiln, and build the kiln into an integral channel, which is usually called a "tunnel kiln" in the industry. Resistance heating elements are installed in the gap formed between the inner wall surface of the kiln wall and the outer wall surface of the furnace tube for heating. The hot gas volume is transferred to the heating box to heat the items placed on the carrying tray.

[0003] When the existing modular heating furnace body pulls out the carrying tray to observe or process the heated items placed on it, the hot gas emitted by the furnace body will continuously discharge from the heating box as the carrying tray is pulled out. This will not only cause the hot gas to impact the face of the pulling personnel, causing discomfort to the personnel, but also cause continuous loss of hot gas.

[0004] Therefore, in view of this, the utility model proposes a modular furnace body to make up for and improve the deficiencies of the existing technology. Content of the Utility Model

[0009] A pulling component, which is arranged between the heating box and the carrying tray, and the pulling component is used to control the sealing door to drive the carrying tray to be in a pulled-out state and a retracted state, and when the carrying tray is in the pulled-out state, the sealing door flips to block the ventilation hole while pulling the carrying tray to extend out of the heating box.

[0010] Preferably, the pulling component includes a positioning column fixedly connected to the inner wall of the heating box. The end of the positioning column away from the heating box is rotatably connected to a shifting seat. A limiting groove is opened on the shifting seat, and the limiting groove is slidably adapted to the carrying tray. A buckling block is fixedly connected to the low end of the shifting seat.

[0011] Preferably, the pulling component further includes a support seat fixedly connected to the inner wall of the heating box. One end of the support seat is fixedly connected to a spring, and the end of the spring away from the support seat is fixedly connected to a positioning seat, and the positioning seat is fixedly connected to the carrying tray.

[0012] Preferably, a handle is fixedly connected to the outer surface of the sealing door, and a magnetic ring is fixedly connected to the outer surface of the heating furnace body, and the handle is magnetically connected to the magnetic ring.

[0013] Preferably, a first sliding column is fixedly connected to the outer surface of the sealing door, and the supply chute is in an "L" shape.

[0014] Preferably, a second sliding column is fixedly connected to the outer surface of the carrying tray, and the diameter of the second sliding column is smaller than the width of the limiting groove.

[0032] The pulling assembly 3 includes a positioning column 33 fixedly connected to the inner wall of the heating box 1. One end of the positioning column 33 away from the heating box 1 is rotatably connected to a shifting seat 31. A limiting groove 32 is opened on the shifting seat 3, and the limiting groove 32 is slidably adapted to the bearing tray 4. A deduction block 34 is fixedly connected to the low end of the shifting seat 31;

[0033] The pulling assembly 3 further includes a support seat 35 fixedly connected to the inner wall of the heating box 1. One end of the support seat 35 is fixedly connected to a spring 36. One end of the spring 36 away from the support seat 35 is fixedly connected to a positioning seat 37, and the positioning seat 37 is fixedly connected to the bearing tray 4;

[0034] A handle 7 is fixedly connected to the outer surface of the sealing door 5. A magnetic ring 8 is fixedly connected to the outer surface of the heating furnace body 2, and the handle 7 is magnetically connected to the magnetic ring 8;

[0035] The above-mentioned scheme is adopted: through the coordinated use of the shift seat 31 and the spring 36 and other structures, the sealing door 5 can be used to slide along the supply slide groove 6, and the sealing door 5 can squeeze the buckle block 34, so that the buckle block 34 carries the shift seat 31 to rotate along the positioning column 33, so that the rotation of the shift seat 31 drives the carrying tray 4 to slide to the outside of the heating box 1, and prompts the sealing door 5 to seal the vent 9, which is beneficial for personnel to observe or process the heated items placed on the carrying tray 4, preventing the continuous discharge of hot air from causing discomfort to personnel, and preventing the continuous discharge of hot air from causing waste.

[0036] Wherein: the outer surface of the sealing door 5 is fixedly connected to a first sliding column, and the sliding groove 6 is "L" shaped;

[0039] The working principle and use process of this utility model:

[0040] For the convenience of description and understanding, this working process is mainly described by the pulling state and the retracting state:

[0041] In the pulling and pulling state: the staff first holds the handle 7 and pulls it obliquely toward the bottom of the heating box 1, so that the sealed door 5 slides along the "L"-shaped supply slide 6 toward the inside of the heating box 1 until the sealed door 5 completely blocks the vent 9, and in the process of moving the sealed door 5, squeezes the buckle block 34, so that it carries the shift seat 31 to rotate along the positioning column 33, so that the rotation of the shift seat 31 shifts the carrying tray 4 to slide toward the outside of the heating box 1, and the spring 36 is stretched and extended by force until the carrying tray 4 slides out of the heating box 1. At the same time, the handle 7 is magnetically connected to the magnetic ring 8 to stop the moving state of the carrying tray 4 and the sealed door 5;

[0042] In the retracted state: Reversing the above working process, the staff pulls the handle 7 to separate the handle 7 from the magnetic ring 8. At this time, the spring 36 rebounds, pulling the carrying tray 4 to slide back toward the inside of the heating box 1, and the sealing door 5 slides along the "L"-shaped slide groove 6 until the sealing door 5 is restored to block the opening position of the heating box 1.
