Description

Technical field:

[0001] The utility model belongs to the field of medium frequency electric furnace charging, in particular to a medium frequency electric furnace charging vehicle. Background technology:

[0002] A medium frequency furnace is a power supply device that converts 50HZ industrial frequency alternating current into medium frequency (300HZ to 1000HZ). It rectifies three-phase industrial frequency alternating current into direct current, and then converts direct current into adjustable medium frequency current to supply the medium frequency alternating current flowing through the capacitor and induction coil, generating high-density magnetic lines in the induction coil, cutting the metal material contained in the induction coil, and generating large eddy currents in the metal material.

[0003] Medium frequency electric furnaces are needed in the production process of electrolytic aluminum, and during the operation of the medium frequency furnace, materials (low-phosphorus pig iron) need to be added to the furnace. During the addition process, electromagnetic cranes are generally used in existing medium frequency furnaces. The main disadvantage of this method is that the single addition amount is small. There are generally multiple medium frequency electric furnaces in the production workshop. The electromagnetic crane installed on the overhead crane needs to travel back and forth between the hopper and the medium frequency furnace many times, resulting in a long time-consuming addition and low efficiency, which affects the normal working efficiency of the medium frequency furnace. In addition, during the addition process, the operator is also required to manually control the direction of the feeding chute so that the material can accurately enter the furnace, resulting in a high labor intensity for the operator. In addition, the leakage of high-temperature airflow in the furnace during addition can easily scald the operator and cause safety accidents. Utility model content:

[0004] The purpose of the utility model is to provide a medium frequency electric furnace charging vehicle, and overcome the deficiencies of the above-mentioned prior art, and effectively solve the existing problem of low charging efficiency of the medium frequency electric furnace.

[0006] Furthermore, the elastic buffer assembly includes an inverted L-shaped bracket, which is arranged at the four bottom corners of the storage hopper, the bottom end of the inverted L-shaped bracket is fixedly connected to the top wall of the turntable, a spring is installed on the top cross bar of the inverted L-shaped bracket, a support arm is installed at the bottom end of the spring, and the inner end of the support arm is fixedly connected to the side wall of the storage hopper.

[0007] Furthermore, a rotating rod is rotatably connected to the top cross bar of the inverted L-shaped bracket, the top hook of the spring is hung on the rotating rod, and an anti-drop cap is installed on the outer end of the rotating rod.

[0008] Furthermore, a reinforcing rib is installed between the inverted L-shaped bracket and the turntable.

[0010] Furthermore, the bottom wall of the storage hopper is inclined downward, and the inclination angle of the bottom wall of the storage hopper is the same as the inclination angle of the feeding trough.

[0011] The beneficial effects of the utility model are as follows: the charging vehicle can be used to quickly charge the medium frequency electric furnace, thereby shortening the time used for charging multiple medium frequency electric furnaces, improving the charging efficiency, ensuring the normal use of the medium frequency electric furnace, and also reducing the work intensity of on-site operators to avoid safety accidents.

[0013] Figure 2 It is a left view of the utility model;

[0014] In the figure, 1 is a traveling vehicle, 2 is a driving motor, 3 is a turntable, 4 is a storage hopper, 5 is a vibration motor, 6 is a discharging port, 7 is a feeding trough, 8 is an inverted L-shaped bracket, 9 is a spring, 10 is an arm, 11 is a rotating rod, 12 is an anti-dropping cap, and 13 is a reinforcing rib. Specific implementation method:

[0015] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:

[0016] like Figure 1 to Figure 2As shown, the medium frequency electric furnace charging vehicle comprises a traveling vehicle 1, a driving motor 2 is installed in the carriage of the traveling vehicle 1, a turntable 3 is installed on the top of the rotating shaft of the driving motor 2, the bottom wall of the turntable 3 is slidably fitted with the top wall of the traveling vehicle 1, the turntable 3 is connected to the storage hopper 4 through an elastic buffer component, a vibration motor 5 is installed on the storage hopper 4, a discharge port 6 is opened on the side wall of the storage hopper 4, a feeding trough 7 matching the discharge port 6 is installed on the side wall of the storage hopper 4, the elastic buffer component comprises an inverted L-shaped bracket 8, the inverted L-shaped bracket 8 is arranged at the four bottom corners of the storage hopper 4, and the bottom end of the inverted L-shaped bracket 8 It is fixedly connected to the top wall of the turntable 3, a spring 9 is installed on the top cross bar of the inverted L-shaped bracket 8, and a support arm 10 is installed at the bottom end of the spring 9, the inner end of the support arm 10 is fixedly connected to the side wall of the storage hopper 4, and a rotating rod 11 is rotatably connected to the top cross bar of the inverted L-shaped bracket 8, the top hook of the spring 9 is hung on the rotating rod 11, and an anti-drop cap 12 is installed at the outer end of the rotating rod 11, and a reinforcing rib 13 is installed between the inverted L-shaped bracket 8 and the turntable 3, the angle of the feeding trough 7 is inclined downward, the bottom wall of the storage hopper 4 is inclined downward, and the inclination angle of the bottom wall of the storage hopper 4 is the same as the inclination angle of the feeding trough 7.

[0017] Specifically, the charging cart can be used to quickly feed materials into the medium frequency electric furnace, thereby improving the charging efficiency.

[0018] During actual use, first fill the storage hopper 4 with materials, then operate the traveling vehicle 1 to drive to the medium frequency electric furnace that needs to be charged. At this time, the operator stays away from the charging port of the medium frequency electric furnace and operates the control handle to start the driving motor 2. The turntable 3 drives the feeding trough 7 to rotate to the charging port of the medium frequency electric furnace. When the discharge port of the feeding trough 7 is aligned with the charging port of the medium frequency electric furnace, the vibration motor 5 is started. The material in the storage hopper 4 enters the feeding trough 7 through the discharge port 6 under the action of vibration. After continuous vibration, the material slides from the feeding trough 7 into the medium frequency electric furnace. After the vibration stops, the material stops being added to the medium frequency electric furnace, and the traveling vehicle 1 is operated to charge other medium frequency electric furnaces.

[0019] During the vibration feeding process, the vibration generated by the storage hopper 4 is transmitted to the spring 9 through the support arm 10, thereby preventing the storage hopper 4 from having a hard contact with the turntable 3; the rotating rod 11 rotatably connected to the top crossbar of the inverted L-shaped bracket 8 can make the storage hopper 4 reciprocate at a small angle during vibration, thereby improving the effect of vibration feeding;

[0020] During the vibration feeding process, the bottom walls of the feeding trough 7 and the storage hopper 4 having the same inclination angle improve the effect of vibration unloading, thereby further improving the efficiency of vibration feeding.

[0021] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
