Description

Technical Field

[0001] This utility model belongs to the technical field of vertical mills, and in particular relates to an automatic slag discharge device for vertical mills with load-bearing induction. Background Technology

[0002] The slag discharge device of a vertical mill is an important component for removing slag in grinding equipment. It plays a crucial role in ensuring the efficient operation of the mill and material handling. During slag discharge, a counterweight flap valve is required to lock the airflow. The counterweight flap valve is a type of valve commonly used in industrial automation control. It automatically controls material flow through the gravity of the counterweight and is widely used in dust collectors, mills, dryers, silos, and other equipment as a discharge and airlock device. However, it still has the following drawbacks in actual use:

[0003] When the slag discharge device operates through the counterweight flap valve, when the weight of the material in the upper space of the counterweight flap valve reaches a certain weight, it will press open the flap valve raft plate, thereby achieving the dual functions of airlock and material discharge. However, the counterweight flap valve opens and closes too frequently. During normal production, it is usually in a constantly open state, which will cause a large amount of cold air to enter the mill, resulting in heat loss and increased energy consumption.

[0004] When the slag discharge device operates through the counterweight flap valve, the material above will accumulate and cause bridging. During the material discharge process, material accumulation is likely to occur, resulting in insufficient material discharge from the steel plate valve. Utility Model Content

[0005] The purpose of this utility model is to provide a vertical mill load-bearing induction automatic slag discharge device. By setting up a transfer box, material level switch, discharge hopper and fixing frame, it solves the problems of excessive switching when the slag discharge device operates through the hammer flap valve, the hammer flap valve is usually in a constantly open state, resulting in large heat loss and insufficient material discharge from the slag discharge device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an automatic slag discharge device for a vertical mill with load-bearing induction, comprising a transfer box, a material level switch, a discharge hopper, and a fixing frame. An output frame is fixedly connected to the bottom of the transfer box, a material level switch is fixedly connected to one side of the output frame, a discharge hopper is fixedly connected to the bottom of the output frame, and an output square tube is fixedly connected to the bottom of the discharge hopper. A fixing frame is fixed to one side of the output square tube, and a gate is movably connected inside the output square tube. During operation, the slag is transferred and transported through the transfer box. When the material level switch is activated, once the slag level rises to the depth corresponding to the material level switch, a pneumatic push rod is activated to pull the gate rod out of the output square tube, and the pneumatic push rod is fixed within the fixing frame.

[0008] Furthermore, a fixed opening is provided on one side of the transfer box, and a ramp is fixed at the bottom of the transfer box away from the fixed opening. When the transfer box is in operation, the slag is transported into it through the fixed opening, and the slag is concentrated and transported to the output frame through the ramp.

[0009] Furthermore, a fixing hole is provided through one side of the output frame, and a material level switch is fixed through the fixing hole. When the output frame is working, the material level switch is fixed through the fixing hole.

[0010] Furthermore, an air inlet pipe is fixedly connected to one side of the discharge hopper, and an electric control valve is fixed around the air inlet pipe. When the discharge hopper is working, high-pressure air is delivered to the discharge hopper through the air inlet pipe, and the delivery of high-pressure air in the air inlet pipe is controlled by the electric control valve.

[0011] Furthermore, the output square tube has an opening on its upper inclined surface, and the gate is movably connected inside the opening. The gate and the inner wall of the output square tube away from the opening abut against each other, and the output square tube is movably connected to the gate through the opening.

[0012] Furthermore, a pneumatic push rod is fixed inside the fixed frame, and the telescopic end of the pneumatic push rod is fixed to the gate. The fixed frame is fixed on the inclined surface above the output square tube outside the socket. The gate is driven to be pulled out and inserted into the output square tube by the pneumatic push rod.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of excessive switching and high heat loss in the slag discharge device when the counterweight flap valve is constantly open, due to the use of a transfer box, a material level switch, a discharge hopper, and a fixing frame. When slag enters the transfer box, it first accumulates in the output square tube above the gate, then in the discharge hopper. After the discharge hopper is full, it accumulates in the output frame. Once the material level reaches the material level switch, the pneumatic pusher is activated, driving the gate to exit the output square tube, allowing the slag to be transported to the receiving equipment. Five minutes after slag discharge, the pneumatic pusher is activated again, pushing the gate back into the output square tube to continue accumulating slag. This allows the slag discharge to be adjusted according to actual working conditions, reducing heat loss within the vertical mill during slag discharge.

[0015] This invention solves the problem of insufficient material discharge from the slag discharge device by setting up a transfer box, a material level switch, and a discharge hopper. The slag is transported to the transfer box through a fixed port. The slag entering the transfer box is concentrated into the output box with the help of the ramp, and then transported to the discharge hopper through the output box. The discharge hopper is then transported to the output square tube, where it is blocked by a gate. The slag then accumulates. When the slag accumulates to the output box and the material level rises to the level corresponding to the material level switch, the electric control valve is opened. High-pressure gas is delivered to the discharge hopper through the air inlet pipe, which blows away the slag in the discharge hopper, preventing bridging between materials and making the material discharge from the slag discharge device smoother.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1

[0026] Please see Figure 1-6 This utility model relates to an automatic slag discharge device for a vertical mill with load-bearing induction, comprising a transfer box 1, a material level switch 2, a discharge hopper 3, and a fixed frame 4. An output frame 104 is fixedly connected to the bottom of the transfer box 1. When the transfer box 1 is in operation, the slag from the vertical mill is input into it and then transferred to the output frame 104, from where it is discharged to the discharge hopper 3. A material level switch 2 is fixedly connected to one side of the output frame 104. When the slag level rises to the level corresponding to the material level switch 2, the pneumatic pusher in the fixed frame 4 is activated. Rod 401 is activated, and the electric control valve 302 is started. The bottom end of the output frame 104 is fixedly connected to the discharge hopper 3. The slag is discharged into the output square tube 303 through the discharge hopper 3. The bottom end of the discharge hopper 3 is fixedly connected to the output square tube 303. The slag is discharged into the receiving equipment through the output square tube 303. A fixing frame 4 is fixed on one side of the output square tube 303. The pneumatic push rod 401 is fixed in the fixing frame 4. A gate plate 402 is movably connected inside the output square tube 303. The output square tube 303 is closed by the gate plate 402.

[0027] Specifically, a fixed opening 101 is provided on one side of the transfer box 1, and a ramp 102 is fixed at the bottom edge of the transfer box 1 away from the fixed opening 101. When the transfer box 1 is working, it is connected to the output port of the vertical mill through the fixed opening 101. After the slag enters the transfer box 1, the slag that hits the inner wall of the transfer box 1 is guided to the output frame 104 through the ramp 102.

[0028] Furthermore, a fixing hole 103 is provided through one side of the output frame 104, and a material level switch 2 is fixed through the fixing hole 103. When the output frame 104 is working, the material level switch 2 is fixed through the fixing hole 103.

[0029] Furthermore, an air inlet pipe 301 is fixedly connected to one side of the discharge hopper 3. The end of the air inlet pipe 301 away from the discharge hopper 3 is connected to a high-pressure air conveying pipeline. An electric control valve 302 is fixed around the air inlet pipe 301. After the electric control valve 302 is opened, air is conveyed to the discharge hopper 3 through the air inlet pipe 301 to blow away the slag in the discharge hopper 3, which facilitates the flow of the slag.

[0030] The operation process of this embodiment is as follows: During operation, the slag is transported to the transfer box 1 through the fixed port 101. The slag entering the transfer box 1 is concentrated into the output frame 104 with the cooperation of the ramp 102, and then transported to the discharge hopper 3 through the output frame 104. The discharge hopper 3 is then transported to the output square tube 303, where it is blocked by the gate 402. The slag then accumulates. When the slag accumulates into the output frame 104, it continues until the slag level rises to the level corresponding to the level switch 2. At this time, the electric control valve 302 is opened, and high-pressure gas is transported to the discharge hopper 3 through the air inlet pipe 301, which blows away the slag in the discharge hopper 3 and prevents the materials from bridging. Specific Implementation Example 2

[0031] Please see Figure 1 , 4 5. Based on the first specific embodiment, the output square tube 303 has an inlet 304 on the upper inclined surface. The gate plate 402 is movably connected inside the inlet 304, and the gate plate 402 abuts against the inner wall of the output square tube 303 away from the inlet 304. When the output square tube 303 is working, the gate plate 402 is movably connected through the inlet 304, and the gate plate 402 blocks the slag in the output square tube 303.

[0032] Specifically, a pneumatic push rod 401 is fixed inside the fixed frame 4. The telescopic end of the pneumatic push rod 401 is fixed to the gate 402. The fixed frame 4 is fixed on the inclined surface above the output square tube 303 outside the socket 304. When the fixed frame 4 is working, the gate 402 is driven to be pulled out of the output square tube 303 and the output square tube 303 is reset by the pneumatic push rod 401.

[0033] The operation process of this embodiment is as follows: During operation, after the slag is in the input transfer box 1, the slag first accumulates in the output square tube 303 above the gate 402 and then in the discharge hopper 3. After the discharge hopper 3 is full, it accumulates in the output frame 104. After accumulation, the slag rises to the level switch 2. At this time, the pneumatic push rod 401 is activated. The pneumatic push rod 401 drives the gate 402 to be pulled out of the output square tube 303, so that the slag is transported to the receiving equipment through the output square tube 303. After the slag is output for five minutes, the pneumatic push rod 401 is activated to push the gate 402 into the output square tube 303 to continue accumulating slag.
