DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-3 The utility model provides a chlorination furnace for sponge zirconium production, comprising a chlorination furnace main body 1, an outer wall of the chlorination furnace main body 1 is fixedly sleeved with a cooling structure 2, and an upper end of the side wall of the chlorination furnace main body 1 is fixedly connected with an exhaust structure 3.

[0017] The zirconium-containing raw material is converted into zirconium tetrachloride through the chlorination furnace main body 1. The cooling structure 2 can effectively cool the chlorination furnace main body 1, increase the cooling system, reduce the temperature in the furnace, and reduce the corrosive effect of chlorine. The exhaust structure 3 can optimize the furnace design, reduce the contact area between chlorine and the metal surface, accurately control the flow of chlorine, avoid excessive temperature and excessive chlorine concentration, reduce the corrosiveness to the chlorination furnace, and have strong practicality.

[0018] The cooling structure 2 includes a cooling cylinder 21, which is fixedly sleeved on the outer wall of the chlorination furnace body 1. The two sides of the cooling cylinder 21 are symmetrically connected with a liquid inlet check valve 22 and a liquid discharge check valve 23. The flow direction of the liquid inlet check valve 22 is from the outside of the cooling cylinder 21 to the inside of the cooling cylinder 21, and the flow direction of the liquid discharge check valve 23 is from the inside of the cooling cylinder 21 to the outside of the cooling cylinder 21.

[0019] When the cooling structure 2 needs to be used, it is first connected to the cooling water pump through the liquid inlet one-way valve 22, and cooling water is injected between the cooling cylinder 21 and the chlorination furnace main body 1 to ensure the cooling effect of the chlorination furnace main body 1. At the same time, when the cooling is completed or the cooling water circulation is required, the cooling water in the cooling cylinder 21 can be discharged through the drain one-way valve 23.

[0020] The exhaust structure 3 includes a bracket 34, which is fixedly mounted on the side wall of the chlorination furnace main body 1. A fan 31 is fixedly mounted on the surface of the bracket 34. One end of the fan 31 is connected to the side wall of the chlorination furnace main body 1 through a connecting pipe 32, and the other end of the fan 31 is connected to the exhaust gas treatment device through an exhaust pipe 33. The fan 31 drives the gas to flow from the inside of the chlorination furnace main body 1 to the outside of the chlorination furnace main body 1.

[0021] When the exhaust structure 3 needs to be used, the fan 31 is turned on and the rotation speed of the servo motor in the fan 31 is adjusted to adjust the exhaust speed to ensure the treatment effect of chlorine. At the same time, the circulation speed of chlorine can be controlled. The chlorination furnace body 1 is connected to the fan 31 through the connecting pipe 32, and is connected to the exhaust gas treatment device through the exhaust pipe 33.

Cursors 42 are symmetrically arranged on both sides of the surface of the float 41, and the outer wall of the cursor 42 is covered with a reflective strip.

[0024] When the cooling water enters the cooling cylinder 21, the float 41 will rise with the liquid level of the cooling water, and at the same time will drive the cursor 42 to move upward. When the cursor 42 leaks out of the upper surface of the cooling cylinder 21, it reminds the user that the amount of cooling water has reached a large amount, and it is necessary to open the drain check valve 23 to discharge or stop the supply of cooling water.

[0025] A fixing seat 5 is fixedly mounted on the lower end of the cooling cylinder 21 , and the fixing seat 5 is fixedly mounted on the outer wall of the chlorination furnace body 1 .
