Description

Technical Field

[0001] The utility model relates to a molten salt chlorination furnace, in particular to a slag discharge valve for the molten salt chlorination furnace. Background Art

[0002] The molten salt chlorination furnace is a device for smelting metals. During the smelting process of metals in the molten salt chlorination furnace, a large amount of slag is produced. In order to prevent the slag from affecting the metal smelting efficiency, the molten salt chlorination furnace needs to be deslagging regularly.

[0003] The traditional method of discharging slag from a molten salt chlorination furnace is to discharge the slag directly into a barrel through the slag outlet. Once the barrel is full of slag, a new barrel is replaced. This method has the following problems: During the barrel replacement process, the slag outlet is still discharging slag, and the discharged slag can easily injure or burn workers.

[0004] The current method for molten salt chlorination furnace slag removal involves installing a gate valve at the slag outlet. This valve is closed during barrel replacement to prevent slag discharge from striking or scalding workers. This method presents the following issues: 1. Opening and closing the gate valve is manual, which is time-consuming and labor-intensive. 2. High-temperature slag easily adheres to the gate valve disc, creating significant resistance and preventing smooth opening and closing. Summary of the Invention

[0005] The utility model is to solve the above technical problems and provide a molten salt chlorination furnace slag discharge valve. The slag discharge valve is opened or closed by a cylinder, which saves time and effort. When slag is adhered to the outer surface of the valve core of the slag discharge valve, the torque of the valve core can be increased, and the valve seat will cut off the slag adhered to the valve core, so that the valve core can be opened or closed smoothly.

[0006] The technical solution of this utility model is:

[0007] A molten salt chlorination furnace slag discharge valve includes a ball valve, which is composed of a valve body, a valve seat, a valve stem and a valve core; the special feature of the ball valve is that: a bracket is fixedly installed on one side of the valve body, one side of the valve stem penetrates the bracket, a cylinder is fixedly installed on the bracket, and a transmission mechanism is connected between the valve stem and the piston rod of the cylinder; a manual reducer is fixedly installed on the other side of the valve body, the valve stem and the output shaft of the manual reducer are fixedly installed near the ball valve end, a handwheel is fixedly installed on the input shaft of the manual reducer, a turntable is fixedly installed on the outer end of the output shaft of the manual reducer, and a rocker is installed on the turntable.

[0008] Furthermore, the output shaft of the manual reducer is located at two ends of the manual reducer, one close to the ball valve and the other far away from the ball valve.

[0009] Furthermore, the transmission mechanism includes a swing arm fixedly mounted on the valve stem, a waist-shaped hole is provided on the swing arm, and a pin is fixedly mounted on the piston rod of the cylinder. The pin passes through the waist-shaped hole. During the extension and retraction of the piston rod of the cylinder, the pin drives the valve core to rotate via the swing arm and the valve stem on the left.

[0010] Furthermore, the valve core is hemispherical, the spherical surface of the valve core fits the valve seat, the ball valve is closed, the spherical surface of the valve core separates from the valve seat, and the ball valve is opened.

[0011] Furthermore, the valve core has a hollow structure, low material cost and simple manufacturing process.

[0012] Furthermore, reinforcing ribs are provided on the inner surface of the valve core to improve the structural strength of the valve core.

[0013] Furthermore, a nickel-chromium carbide coating is provided on the outer surface of the valve core to improve the hardness and wear resistance of the valve core spherical surface.

[0014] The beneficial effects of the utility model are:

[0015] 1. A bracket is fixedly installed on one side of the valve body, one side of the valve stem is inserted into the bracket, a cylinder is fixedly installed on the bracket, and a transmission mechanism is connected between the valve stem and the piston rod of the cylinder; during the extension and retraction of the piston rod of the cylinder, the pin shaft drives the valve core to rotate through the swing arm and the valve stem, thereby opening or closing the ball valve, which is convenient and fast, saving time and effort.

[0016] 2. Since the slag discharge valve uses a ball valve, a manual reducer is fixedly installed on the other side of the valve body. The valve stem and the output shaft of the manual reducer are fixed near the ball valve end. A handwheel is fixedly installed on the input shaft of the manual reducer. A turntable is fixedly installed on the outer end of the manual reducer's output shaft, and a rocker is installed on the turntable. When slag adheres to the outer surface of the valve core, turning the handwheel drives the valve core through the manual reducer and the right valve stem. The manual reducer amplifies the input torque, thereby increasing the torque acting on the valve core. The slag adhered to the outer surface of the valve core is sheared off by the valve seat, allowing the valve core to open or close smoothly. If the slag adheres to the outer surface of the valve core too strongly, a jack is placed on the ground below the rocker. The jack is activated to push the rocker, driving the valve core through the turntable and the right valve stem. The jack increases the torque acting on the valve core, shearing off the slag adhered to the outer surface of the valve core by the valve seat, allowing the valve core to open or close smoothly.

[0020] like Figure 1 、 Figure 2 As shown, a molten salt chlorination furnace slag valve includes a ball valve 1, which is composed of a valve body 101, a valve seat 102, a valve stem 103 and a valve core 104.

A manual reducer 7 is fixedly installed on the other side of the valve body 101, and the output shaft of the manual reducer 7 is separated at both ends of the manual reducer 7, close to the ball valve 1 end and away from the ball valve 1 end. The valve stem 103 and the output shaft of the manual reducer 7 are fixedly installed close to the ball valve 1 end. A handwheel 8 is fixedly installed on the input shaft of the manual reducer 7, a turntable 9 is fixedly installed on the outer end of the output shaft of the manual reducer 7, and a rocker 10 is installed on the turntable 9.

[0021] The working principle of this utility model is:

[0022] The inlet of the valve body 101 is fixedly installed at the slag discharge port of the molten salt chlorination furnace. During the slag discharge operation, the barrel is first connected to the outlet of the valve body 101. Then the piston rod of the cylinder 3 is retracted. The pin 6 drives the valve core 104 to rotate through the swing arm 4 and the valve stem 103. The valve core 104 separates from the valve seat 102, and the slag discharge valve opens. The slag produced by the molten salt chlorination furnace is discharged into the barrel through the outlet of the valve body 101. After the barrel is filled with slag, the piston rod of the cylinder 3 is extended. The pin 6 drives the valve core 104 to rotate through the swing arm 4 and the valve stem 103. The valve core 104 closes the valve seat 102, the slag discharge valve is closed, and the barrel is removed and transported to the slag storage area.

[0023] When the outer surface of the valve core 104 is adhered to the slag, the hand wheel 8 is turned to drive the valve core 104 to rotate through the manual reducer 7 and the valve stem 103. The input torque is amplified by the manual reducer 7 to increase the torque acting on the valve core 104. The slag adhered to the outer surface of the valve core 104 is cut off by the valve seat 102 until the valve core 104 closes the valve seat 102, the slag discharge valve is closed, the barrel is removed and transported to the slag storage area.

[0024] When the strength of the slag adhering to the outer surface of the valve core 104 is too high, a jack is placed on the ground below the rocker 10, and the jack is started to push the rocker 10, which drives the valve core 104 to rotate through the turntable 9 and the valve stem 103. The torque acting on the valve core 104 is increased by the jack, and the slag adhering to the outer surface of the valve core 104 is cut off by the valve seat 102 until the valve core 104 closes the valve seat 102, the slag discharge valve is closed, and the barrel is removed and transported to the slag storage area.
