Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention. Example
[0029] A furnace front material distributor equipped with an anti-burning frequency converter comprises a distribution box 1, a material distributor assembly 15 is provided on the front side of the distribution box 1, a filter 16 mounted on the wall is provided on one side of the distribution box 1, a mounting guide rail 2 is detachably mounted on one side of the interior of the distribution box 1, a frequency converter body 3 is detachably mounted on one side of the mounting guide rail 2, a mounting groove 4 is provided on one side of the mounting guide rail 2, a mounting block 5 is slidably mounted inside the mounting groove 4, a socket 6 adapted to the mounting block 5 is provided on one side of the inner cavity of the mounting groove 4, active cavities 7 distributed at equal intervals are provided on one side of the inner cavity of the mounting groove 4, a bayonet 8 is slidably mounted on the inner cavity of the active cavity 7, one end of the bayonet 8 is fixedly connected to a spring 9, and the end of the spring 9 away from the bayonet 8 is fixedly connected to the inner wall of the active cavity 7, and a bayonet 10 adapted to the bayonet 8 is provided on the side of the mounting block 5 facing the bayonet 8.
[0030] The specific usage process is as follows: First, the installation guide rail 2 can be installed by welding. It can also be installed by bolt fixation according to actual usage requirements. This solution is explained in welding. During production and installation, the installation guide rail 2 is first welded to the inner wall of the distribution box 1. The specific position can be determined according to actual needs, and the number of installation guide rails 2 can also be flexibly selected according to actual usage requirements. After the installation guide rail 2 is fixed, the inverter body 3 can be installed. First, install the fixing plate 13 to the inverter body 3 through the fixing bolts 14. During installation, insert the fixing bolts 14 into the fixing plate 13, and then fix the fixing plate 13 to the inverter body 3 through the fixing bolts 14. In addition, a plurality of mounting holes are provided on the fixing plate 13, and it can also be based on Adjust the installation position of the fixing bolt 14 according to actual needs to provide the user with a more flexible and convenient option for installation work and provide convenience for the user's work and use. At this time, the mounting block 5 is also installed on the inverter body 3. Then hold the inverter body 3 and align the mounting block 5 with the socket 6 and snap it in until the mounting block 5 is completely located in the mounting groove 4. At this time, control the inverter body 3 to slide the mounting block 5 to one side. During the movement of the mounting block 5, the surface of the mounting block 5 will squeeze the corresponding bayonet 8, and then the bayonet 8 will retract into the corresponding active cavity 7, while compressing the corresponding spring 9. After the mounting block 5 passes and the slot 10 is aligned with the bayonet 8 at this position, the bayonet 8 will pop out of the inner cavity of the active cavity 7 under the action of the spring 9 and then snap into the slot 10 As the mounting block 5 continues to move, the mounting block 5 squeezes the corresponding bayonet 8 into the corresponding active cavity 7 again. Then, when the slot 10 is aligned with the corresponding bayonet 8 again, the bayonet 8 is snapped into the slot 10 again, and then it is repeated until the mounting block 5 no longer moves. At this time, the corresponding bayonet 8 is snapped into the slot 10 to achieve the positioning and fixation of the mounting block 5. At the same time, the mounting groove 4 can also play a guiding and limiting role for the mounting groove 4, and can also cooperate with the bayonet 8 to play a positioning and fixing role for the mounting block 5, ensuring the stability of the mounting block 5 after installation, and also ensuring the stability of the inverter body 3 after installation. In this way, the user can quickly complete the installation and disassembly of the inverter body 3, and multiple inverter bodies 3 can also be quickly disassembled and assembled, and according to The actual use needs can also flexibly adjust the installation position of the inverter body 3, thereby providing convenience for the user's work and use, wherein the groove 11 and the positioning spring piece 12 are adapted to each other, wherein the groove 11 is opened on the mounting block 5, so when the mounting block 5 moves, the mounting block 5 will first compress the positioning spring piece 12 at the corresponding position, and then after the groove 11 is aligned, the positioning spring piece 12 will be snapped into the groove 11 again, and this is repeated continuously during the movement of the mounting block 5, so that all the positioning spring pieces 12 will continue to be snapped into the corresponding grooves 11, thereby further positioning and fixing the mounting block 5, ensuring the stability of the mounting block 5 after installation, and a "click-click" prompt sound will be heard after the positioning spring piece 12 is snapped into the groove 11,It is convenient for users to respond in time during work and provides convenience for users' work.
[0031] Therefore, a guide rail structure design that can be quickly assembled is adopted. The user only needs to insert the corresponding components on the inverter into the guide rail, and then move and adjust the inverter to the appropriate position, so that the inverter can be quickly positioned at the installation position. The assembly position of the inverter can also be flexibly adjusted according to actual work needs, providing convenience for the user's work.
[0032] When the entire furnace front material distributor is working, the material first enters the feeder 17, and then enters the material distributor assembly 15 under the transportation of the feeder 17, and then is evenly fed into the furnace 18 by the material distributor assembly 15, ensuring that the furnace 18 can operate normally. The material distributor assembly 15 is used to feed the material sent by the feeder 17 into the furnace 18 at a uniform frequency to ensure the uniformity of feeding.

A filter 16 is added to the line inlet of the distribution box 1. An inductor is added to the output terminal 3 of the inverter body.

The feed hopper 155 is connected to the feeder 17, and the discharge hopper 154 is connected to the furnace 18.
[0040] Specifically, the setting of the material leveling component 15 is used to feed the material sent by the feeder 17 into the furnace 18 at a uniform frequency to ensure the uniformity of the feeding. When working, the two stepper motors 152 are started at the same time and rotate in the same direction, thereby driving the two material leveling wheels 153 to rotate at a uniform speed in the same direction, thereby transferring the material entering from the feed hopper 155 to the discharge hopper 154, and finally sending it into the furnace 18 through the discharge hopper 154, thereby realizing uniform feeding of the furnace 18.
