[0023] See also Figure 1-4 As shown, a heat treatment high-efficiency energy-saving tempering and holding furnace comprises a furnace body 1, a filter box 2, a fan 4, a hose 5, a material cart 6, an electromagnet 7, an iron core 8, a hanger 9, a side plate 10, a material-dispensing roller plate 11, a motor 12 and a cylinder 13. The top of the feeding end and the unloading end of the furnace body 1 are both connected and fixed with hangers 9, and a material-dispensing roller plate 11 is provided at the bottom of one of the hangers 9. The material-dispensing roller plate 11 and the material cart 6 located at the feeding end of the furnace body 1 form a dispensing and unloading structure. The iron core 8 is magnetically fixed to the corresponding electromagnets 7 at the bottom of both ends of the furnace body 1, and a bevel mesh frame 603 is slidably installed in the material cart 6. The side bars 601 connected on both sides of the bevel mesh frame 603 are respectively connected to two cylinders 2 13 of the same group. The circular hole 604 on the side of the material cart 6 is plugged into one end of the hose 5 through the cylinder 1 501, and the other end of the hose 5 is connected to the output port of the filter box 2 located at the top of the furnace body 1 through the conduit 3, and a fan 4 is installed on the conduit 3.

[0024] like Figure 1 and Figure 2 As shown, the top of the side bar 601 and the output end of the cylinder 2 13 are connected to each other by a detachable connecting piece, and two groups of cylinder 2 13 are respectively installed on the top of two hangers 9. The cylinder 2 13 is extended and retracted to pull up or push down the inclined mesh frame 603 connected by the side bar 601, which can meet the needs of loading and unloading materials in the material cart.

[0025] like Figure 2As shown, the material cart 6 is respectively distributed at the loading end and the unloading end of the furnace body 1, and universal wheels are installed at the four corners of the bottom of the material cart 6. Side guide grooves 602 are opened on the side walls on both sides of the material cart 6, and the side guide grooves 602 are slidably connected with the corresponding side bars 601. The universal wheels at the bottom of the material cart 6 are used to facilitate transportation and movement, and the side guide grooves 602 located in the material cart 6 ensure the stability of the up and down movement of the side bars 601.

[0026] like Figure 1 and Figure 4 As shown, side plates 10 are rotatably installed at both ends of the material-discharging roller plate 11, and the top ends of the two side plates 10 are fixedly connected to the corresponding parts of the bottom of a hanger 9, one of the side plates 10 is installed with a motor 12, and the motor 12 is connected to the shaft end located on one side of the material-discharging roller plate 11. The motor 12 drives the material-discharging roller plate 11 to rotate at the discharge port of the material cart 6 and contact with the material, which is conducive to displacing the material to the outside of the material cart 6 and dropping it onto the conveyor belt on the furnace body 1.

[0027] When the utility model is in use, a group of cylinders 2 13 located at the feeding end of the furnace body 1 is in a contracted state, and the inclined mesh frame 603 connected by the side bar block 601 is moved from bottom to top in the material cart 5, so that the materials located at the top of the inclined mesh frame 603 in the material cart 5 gradually move up, and at the same time, the motor 12 drives the connected material-pickup roller plate 11 to rotate to push the contacted materials to the conveyor belt area located on the outside of the furnace body 1. At the same time, the cylinder 1 501 inserts one end of the hose 5 connected by the connecting block 503 into the circular hole 604 located on the corresponding material cart 6, and runs the fan 4 to discharge the hot air inside the furnace body 1 connected to the duct 3 and the filter 2 into the material cart 6, so as to preheat the materials. When the materials are loaded and unloaded, the connection and fixation between the cylinder 2 13 and the top of the side bar block 601 are released, the inclined mesh frame 603 falls and resets to the material cart 6, and the magnetic attraction and fixation between the iron core 8 and the electromagnet 7 on the material cart 6 are released, and the material cart 6 is transported and moved;

[0028] Compared with the prior art, a detachable connection is adopted between the material cart and the upper and lower material ends of the furnace body, and at the same time, the inclined mesh frame supporting the material in the material cart is pushed and pulled through the extension and contraction of the cylinder, thereby ensuring that the material moves slowly upward from the material cart, and the material is pushed outward to the conveyor belt on the furnace body by the material-moving roller plate driven by the motor, thereby reducing the tedious time spent on overturning and transporting the material and improving the heat treatment efficiency; the hot air is discharged through the duct connected to the fan and inserted into the round hole through the hose, so as to achieve the effect of introducing the hot air into the material cart and diffusing it from bottom to top, which is beneficial to preheating the material, shortening the time for heating the material in the furnace body, and saving energy and being efficient.
