Description

Technical Field

[0001] The present invention relates to the field of vacuum smelting furnaces, and particularly to a method and device for measuring the temperature of a vacuum smelting furnace with high accuracy. Background Art

[0002] A vacuum smelting furnace is a furnace that uses a vacuum system to discharge some substances in the furnace cavity within a specific space, so that the pressure in the furnace cavity is less than one standard atmospheric pressure, and the space in the furnace cavity thus achieves a vacuum state. The surface of the workpiece to be heated is not oxidized, decarburized, has little deformation, and good mechanical properties. Melting metals with a vacuum smelting furnace is beneficial to removing impurities, with few pinholes, less segregation, and good quality in the finished product, and is suitable for the melting and heating of high-quality, high-purity, and refractory metals.

[0003] Most of the common methods and devices for measuring the temperature of a vacuum smelting furnace with high accuracy on the market are not convenient for lifting the smelting tank, and the discharging is rather troublesome, and the heat dissipation effect of the device is poor. Therefore, we propose a method and device for measuring the temperature of a vacuum smelting furnace with high accuracy. Summary of the Invention

A processing module is arranged at a position near the corner on the right side wall of the main body. Heat dissipation mechanisms are arranged on both sides of the main body. A cover plate is arranged at the upper end of the main body. A connecting pipe is arranged at the upper end of the cover plate. A feeding module is arranged through the connecting pipe at the upper end of the cover plate. A transmission mechanism is arranged inside the main body. A discharge slot is opened at a position on the inner side wall of the main body and on one side of the transmission mechanism. A discharge plate is arranged inside the discharge slot. Temperature sensors are arranged at positions near the corners at the top end inside the main body. The output end of the temperature sensor is electrically connected to the input end of the processing module.

[0007] As a further solution of the present invention: The heat dissipation mechanism includes a baffle. Heat dissipation slots are opened on both side walls of the main body, and a plurality of groups of heat dissipation fins are arranged inside the heat dissipation slots.

[0008] As a further solution of the present invention: A groove is opened at the middle position on the side wall of the baffle. A plurality of groups of dust-proof plates are arranged between the inner side walls of the groove and at the position of the groove opening. Two groups of fans are arranged on the inner side wall of the groove. An air duct is opened at a position on the inner side wall of the groove and on one side of the fan.

[0009] As a further solution of the present invention: The baffle is fixedly arranged on both sides of the main body. The groove is communicated with the heat dissipation groove through the air duct. The cross section of the heat dissipation fin is arranged in an isosceles trapezoid shape.

[0010] As a further solution of the present invention: The transmission mechanism includes a first support plate. Convex blocks are arranged at positions near the corners at the upper end of the first support plate. A connecting plate is arranged on the convex blocks. An activity groove that fits the convex blocks is opened at a position near one side at the upper end of the connecting plate. A bearing plate is arranged at the bottom end of the connecting plate. A smelting tank is arranged on the bearing plate.

[0011] As a further solution of the present invention: Two groups of second support plates are arranged at a position on the bottom end inside the main body and near one side of the first support plate. First support plates are arranged at positions near the left bottom corner at the bottom end of the bearing plate. An electric telescopic rod one is rotatably arranged between the first support plate and the second support plate.

[0012] As a further solution of the present invention: The connecting plate is sleeved on the top of the convex block through the activity groove. Rotating shafts one are arranged between the outer side walls of the two convex blocks and the inner side wall of the activity groove. Rotating shafts two are arranged at both ends of the electric telescopic rod one.

[0013] As a further solution of the present invention: A vertical plate is arranged at the bottom end inside the main body. A horizontal groove is opened at the upper end of the vertical plate. A second support plate is arranged between the inner side walls of the horizontal groove. Connecting frames are arranged at the bottom end inside the main body and at the top of the second support plate. An electric telescopic rod two is rotatably arranged between the two connecting frames.

[0014] As a further solution of the present invention: Rotating shafts three are arranged between the outer side walls of the second support plate and the inner side wall of the horizontal groove. The top of the second support plate is located at a position near the edge below the smelting tank.

[0015] A method for measuring the temperature of a vacuum smelting furnace with high accuracy. The specific temperature measurement method is as follows.

[0016] Step 1: The staff grabs the raw materials through the feeding module, and then sets the bottom of the feeding module on the upper end of the cover plate through the connecting pipe. Then the feeding module adds the raw materials into the smelting tank. The smelting tank smelts the raw materials. At this time, the temperature sensor will measure the temperature inside the main body and transmit the measured temperature to the processing module. By arranging temperature sensors at positions near the corners at the top inside the main body, the temperature at different positions of the main body can be measured, effectively improving the accuracy of temperature measurement. The processing module analyzes the temperatures measured by the four temperature sensors, so as to know the temperature inside the main body during operation.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. Start the electric telescopic rod 1 and the electric telescopic rod 2 at the same time. The electric telescopic rod 2 applies a thrust to the top position of the support plate 2 through the connecting frame. At this time, the support plate 2 applies a thrust to the bottom end of the smelting tank near the edge through the rotating shaft 3 and the horizontal groove opened on the top of the vertical plate. The electric telescopic rod 1 extends and applies a thrust to the bottom end of the bearing plate near the support plate 1. At this time, the bearing plate drives the smelting tank to rotate counterclockwise around the top position of the protrusion through the connecting plate and the movable groove in cooperation with the rotating shaft 1. At this time, the electric telescopic rod 1 can cooperate with the rotating shaft 2 through the bracket plate 1 and the bracket plate 2 as the bearing plate rotates counterclockwise and continuously applies a thrust to the bearing plate. Through the above operation, the bearing plate can wait for the smelting tank to rotate counterclockwise, and pour the raw materials inside the smelting tank into the discharge trough opened at the upper end of the unloading plate to facilitate unloading.

[0019] 2. Heat dissipation slots are provided on both sides of the main body, and several groups of heat sinks are arranged inside the heat dissipation slots. The heat sinks will absorb the heat from the surface of the main body and dissipate the heat into the air. The two groups of fans arranged on the baffle are started, and the fans blow air into the heat dissipation slots through the grooves and the wind slots to accelerate the flow of airflow inside the heat dissipation slots. When the airflow flows through the surface of the heat sink, it will take away the heat, thereby accelerating the heat dissipation and effectively improving the heat dissipation effect.
