Description

Technical Field

[0001] The utility model relates to the technical field of tantalum carbide preparation equipment, in particular to a tantalum carbide carbonization furnace. Background Art

[0002] Tantalum carbide is a light brown metallic cubic crystalline powder belonging to the sodium chloride type cubic crystal system. It is mainly used as an additive for powder metallurgy, cutting tools, fine ceramics, chemical vapor deposition, hard wear-resistant alloy cutting tools, tools, molds and wear-resistant and corrosion-resistant structural parts to improve the toughness of the alloy. Tantalum carbide needs to be prepared using a special carbonization furnace to sinter the raw materials.

[0003] In the preparation of existing tantalum carbide, the raw materials are generally directly placed into a carbonization furnace and an inert gas is filled into the furnace body to sinter it. Since the raw materials are in a piled state, it is difficult for the raw materials at the bottom to fully contact with the inert gas, which can easily affect the thoroughness of the raw material reaction and further affect the preparation of tantalum carbide. For this reason, we provide a tantalum carbide carbonization furnace. Utility Model Content

[0011] As a further improvement of the above solution, a discharge port is provided on the furnace body, and a sealed movable door is hinged on the outside of the discharge port.

[0012] As a further improvement of the above solution, a transparent observation window is provided on the sealed movable door.

[0013] As a further improvement of the above solution, an air inlet pipe is fixedly connected to the back of the furnace body.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model drives the bevel gear to rotate through a motor, utilizes the meshing action between the bevel gear and the bevel gear ring, so as to drive the screw tube to rotate, utilizes the threaded connection between the screw tube and the screw rod, and the sliding cooperation between the guide rod and the furnace body, so as to drive the circular connecting plate to move vertically downward, and the vertical downward movement of the circular connecting plate drives the strip plug block to move vertically downward, so that the strip plug block can be inserted into the raw material for preparing tantalum carbide. At this time, the inert gas can enter the insertion hole to contact the raw material at the bottom, effectively avoiding the problem that the accumulated raw materials are difficult to fully contact with the inert gas, which affects the preparation of tantalum carbide.

[0016] 2. In the process of driving the strip-shaped plug to move vertically downward, the utility model can also drive the vertical rod to move downward together. The downward movement of the vertical rod drives the ball to move downward. The movable connection between the ball and the T-shaped connector, the cooperation between the ball and the spiral groove, and the rotational cooperation between the vertical rod and the circular connecting plate enable the vertical rod to rotate. The rotation of the vertical rod drives the strip-shaped plug to rotate, so that the size of the plug hole can be increased, thereby facilitating the entry of inert gas, further ensuring the thoroughness of the reaction for preparing tantalum carbide raw materials, and having strong practicality.

[0027] The implementation principle of a carbonization furnace for tantalum carbide in the embodiment of the present application is as follows: first, the sealed movable door is opened and the raw material is placed inside the furnace body 1, then the sealed movable door is closed and inert gas is filled into the furnace body 1 through the air inlet pipe 6, then the raw material is sintered, and then the motor 4 is started, and the bevel gear 5 is driven to rotate by the motor 4, and the meshing action between the bevel gear 5 and the bevel gear ring 3 is utilized to drive the screw tube 2 to rotate, and the threaded connection between the screw tube 2 and the screw rod 103 and the sliding cooperation between the guide rod 109 and the furnace body 1 are utilized to drive the circular connecting plate 101 to move vertically downward, and the vertical downward movement of the circular connecting plate 101 drives the strip plug 102 to move vertically downward, so that the strip plug 102 can be inserted into the furnace body for preparing tantalum carbide.
