[0029] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0030] Example 1, a smart melting equipment, referring to Figure 1 and Figure 2 , including a rack 1, the rack 1 is a stainless steel rack, and the rack 1 has a plurality of steps.

[0031] A material storage box 2, a melting furnace 3, a quantitative furnace 4 and a dry pot 5 are fixedly installed on the steps of the frame 1;

[0032] The material storage box 2 is located above the melting furnace 3;

[0033] The melting furnace 3 is located above the dosing furnace 4;

[0034] The quantitative furnace 4 is located above the dry pot 5 .

[0035] The frame 1 is provided with an inclined conveyor belt 11 for feeding materials to the storage box 2 . The end of the inclined conveyor belt 11 is located at the upper end of the storage box 2 . The aluminum strip is conveyed to the upper end of the storage box 2 by the inclined conveyor belt 11 .

[0036] A downwardly folded flap 61 is provided at the upper end of the storage box 2 . The aluminum strip is conveyed to the flap 61 by the inclined conveyor belt 11 . Due to the gravity of the aluminum strip, the flap 61 rotates downward and opens, and the aluminum strip enters the storage box 2 .

[0037] When the aluminum strips are put in, the flap 61 will automatically rotate upwards and seal; the flap 61 is rotatably connected to the top of the storage box 2, and the two are connected by a rotating shaft; an elastic member 62 is installed on the rotating shaft of the flap 61, and the elastic member 62 is a torsion spring. Under the elastic force of the torsion spring, the flap 61 can automatically rotate upwards and reset; the edge of the storage box 2 is provided with a flange 63, which will block the flap 61, so as to limit the rotation of the flap 61 and seal it. A seal can be set on the flange 63 to increase the sealing performance of the flap 61.

[0038] The flap 61 contacts the flange 63 , and the flap 61 cannot be further rotated upward to open. Due to the contact relationship, the flap 61 and the flange 63 contact the edges to achieve sealing.

[0039] The storage box 2 is also fixed with a top plate 71, and a vacuum pump 72 is provided on the bottom plate top plate 71. The vacuum pump 72 is used to extract air from the storage box 2 to extract water vapor and impurities, thereby ensuring the cleanliness of the aluminum strip and making the molten aluminum water cleaner.

[0040] A conveyor belt 21 is provided in the storage box 2, and a pipe 22 connected to the furnace 3 is opened at the bottom of the storage box 2. The pipe 22 is located at the end of the conveyor belt 21. The cross-section of the pipe 22 is a long strip, and the length of the pipe 22 is greater than the length of the aluminum bar, and the width of the pipe 22 is greater than the width of the aluminum bar. Such a design ensures that the aluminum bar can smoothly slide into the pipe 22 and slide downward through the pipe 22; in other embodiments, an aluminum bar with a width and thickness that is smaller than the width of the pipe can be selected, and such an aluminum bar can slide into the pipe 22 more conveniently and smoothly.

[0041] The aluminum bars entering the storage box 2 enter the conveyor belt 21. The conveyor belt 21 has a buffering effect on the fallen aluminum bars, and secondly a transportation effect. The conveyor belt 21 transports the aluminum bars to the upper pipe mouth position of the pipeline 22. The aluminum bars automatically slide down after reaching the end of the conveyor belt 22. The aluminum bars dropped from the conveyor belt 21 slide smoothly into the pipeline 22. The storage box 2 is filled with 40 kilograms of aluminum bars. In other embodiments, the weight of the aluminum bars loaded in the storage box can be adjusted according to actual needs.

[0042] The conveyor belt 21 conveys the aluminum bars to the position of the pipe 22, and the aluminum bars enter the interior of the melting furnace 3 through the pipe 22.

[0043] An electric heating wire is provided at the bottom of the melting furnace 3 to heat and melt the aluminum strips. In other embodiments, the aluminum strips can also be heated and melted by gas combustion.

[0044] A flow valve assembly 31 is provided at the bottom of the melting furnace 3, and the flow valve assembly 31 is connected to the quantitative furnace 4 below. The flow valve assembly 31 includes an intelligent valve 311 and a floating ball 312 for controlling the closing of the intelligent valve 311, and the floating ball 312 is located in the quantitative furnace 4. The intelligent valve 311 is connected to a valve opening button 313, and the valve opening button 313 is a foot pedal button.

[0045] The quantitative furnace 4 is provided with a discharge nozzle 41, and the discharge nozzle 41 is provided with a switch valve body 42. The quantitative furnace 4 is provided with an electric heating wire, and the electric heating wire is used to keep the furnace body warm.

[0046] Working principle: Aluminum bars enter the storage box 2, and are evacuated to remove moisture. Then, the aluminum bars are transported to the melting furnace 3 below for melting. Then, the molten metal is put into the quantitative furnace 4. The float 312 in the quantitative furnace 4 gradually rises. When the float 312 floats to the designed height, the smart valve 311 is closed, and the metal in the quantitative furnace 4 is easily a standard unit volume. The floating ball 312 controls the closing of the smart valve 311. The opening of the smart valve 311 requires the staff to actively operate it, that is, to step on the valve opening button 313; when the aluminum liquid in the quantitative furnace 4 is discharged, the staff opens the smart valve 311 again through the valve opening button 313, and the aluminum liquid in the melting furnace 3 enters the quantitative furnace 4 again.

[0047] At this time, the staff opens the switch valve body 42, and the unit volume of the molten metal can all flow into the dry pot 5, and then closes the switch valve body 42, and the staff opens the smart valve 311. The switch valve body 42 can be controlled by a manual button or a foot pedal button.

[0048] Such a design ensures that the dry pot 5 is loaded with a fixed amount of molten metal each time, and will not be overfilled.

[0049] Embodiment 2, a smart melting equipment, which is different from embodiment 1 in that a liquid containing basin 81 is provided below the dry pot 5, and a weighing alarm 82 is provided below the liquid containing basin 81, and the weighing alarm 82 is provided with an alarm threshold. When the total weight of the dry pot 5, the molten metal and the liquid containing basin 81 is greater than the alarm threshold, the weighing alarm 82 will emit a buzzing alarm sound; the dry pot 5 is placed in the liquid containing basin 81, which is convenient for taking and placing the dry pot 5, and also convenient for the liquid containing basin 81 to receive the molten metal when the molten metal overflows, so as to prevent the molten metal from flowing around. This design is to avoid the situation that when the flow valve body combination fails, the excess molten metal in the quantitative furnace 44 is all introduced into the dry pot 5, causing the molten metal in the dry pot 5 to overflow and scald the feet of employees.

[0050] The weighing alarm 82 of the present invention can remind the staff to close the upstream valve body in time. The liquid containing basin 81 can receive part of the overflowed molten metal, which can reduce the rapid splashing of the molten metal to the surrounding areas.

[0051] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
