[0002] Tungsten and molybdenum are two important metal elements, which are often used to make alloy materials and high-temperature and high-pressure equipment. Due to the similar physical and chemical properties of the two, how to effectively separate tungsten and molybdenum has become an important issue in industrial production. Common methods for separating tungsten and molybdenum include acid-base valve, complex precipitation method and ion exchange method.

[0003] This method is to add a complexing agent to the solution to form a stable complex between tungsten and molybdenum, and then adjust the conditions to precipitate the complex to achieve separation. Commonly used complexing agents include oxalic acid, citric acid, etc., which can form a stable complex with tungsten and molybdenum and precipitate under specific conditions.

[0004] However, in the process of using a complexing agent to form a stable complex between tungsten and molybdenum, molybdenum reacts with oxalic acid to generate sulfur dioxide gas, which is harmful to the health of operators. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] See also Figure 1 , Figure 2 , Figure 3 The figure shows a tungsten-molybdenum separation device, which includes a reaction vessel 1. A material trough 2 for containing tungsten-molybdenum raw materials is installed inside the reaction vessel 1. The material trough 2 is in the shape of a circular ring, and a through hole is arranged on the surface of the material trough 2. A supporting ring 3 is movably abutted against the lower end of the material trough 2. The supporting ring 3 and the material trough 2 are both made of plastic; a protective structure 4 is installed at the upper end of the reaction vessel 1 to prevent carbon monoxide from harming the environment.

[0029] See also Figure 3The protective structure 4 includes a protective cover 401 movably embedded in the upper end of the reaction vessel 1, and the shape of the protective cover 401 is conical. Two symmetrically distributed electric push rods 5 are fixedly installed on the outer side of the reaction vessel 1. The upper ends of the electric push rods 5 are fixedly connected to the protective cover 401 through a fixing plate. A silicone pressure ring 402 is fixedly embedded on the outer side of the protective cover 401, and the lower end surface of the silicone pressure ring 402 is movably fitted with the upper end surface of the reaction vessel 1. The protective cover 401 is made of transparent plastic.

[0030] See also Figure 4 A conduit 403 is fixedly embedded in the upper end of the protective cover 401, and one end of the conduit 403 away from the protective cover 401 is fixedly connected to the recovery tank, and the support ring 3 is fixedly connected to the protective cover 401 through a fixing rod made of plastic.

[0031] The working principle capable of avoiding harmful gases from harming health is as follows: a worker places the tungsten-molybdenum raw materials in the material holding trough 2, and then places the material holding trough 2 on the supporting ring 3 on the lower side of the protective cover 401, and then controls the electric push rod 5 to operate through the controller, and the electric push rod 5 drives the protective cover 401 and the material holding trough 2 to move downward. When the material holding trough 2 is completely immersed in the oxalic acid solution in the reaction vessel 1, the silicone pressure ring 402 on the outer side of the protective cover 401 fits the upper port of the reaction vessel 1, and a large amount of harmful gases generated during the reaction between the tungsten-molybdenum raw materials and oxalic acid are shrouded in the protective cover 401, which can effectively avoid the spread of harmful gases to affect human health or pollute the natural environment.

[0032] Embodiment 2

[0033] See also Figure 2 , Figure 5 This embodiment further explains Example 1. A sealing assembly 6 is installed inside one end of the catheter 403 close to the protective cover 401. The sealing assembly 6 includes an embedded tube 601 movably embedded in the lower end of the catheter 403, and the embedded tube 601 can move up and down inside the catheter 403. The outer wall of the embedded tube 601 is movably fitted with the inner wall of the catheter 403.

[0034] See also Figure 5 The lower end of the embedded tube 601 is in a closed state, a push rod 7 is fixedly embedded at the bottom center of the reaction dish 1, and the upper end of the push rod 7 is movably abutted against the lower end of the embedded tube 601, and the upper end of the embedded tube 601 is located inside the conduit 403 and is movably abutted against a spring 602, which can drive the embedded tube 601 to move downward, and the upper end of the spring 602 is movably abutted against a retaining ring 603, and the connection between the retaining ring 603 and the conduit 403 is a fixed connection, and the retaining ring 603 is made of plastic.

[0035] See also Figure 6Two symmetrically distributed limiting straight grooves 604 are provided on the outer side of the embedded tube 601, and a rubber ring 606 is fixedly embedded on the outer side of the embedded tube 601. The rubber ring 606 can increase the sealing between the embedded tube 601 and the conduit 403. A plurality of circumferentially equidistantly distributed exhaust holes 607 are provided on the embedded tube 601 and the conduit 403, and the exhaust holes 607 on the embedded tube 601 are located at the lower side of the rubber ring 606. When the exhaust holes 607 on the conduit 403 overlap with the exhaust holes 607 on the embedded tube 601, the gas can flow in the conduit 403.

[0036] In this embodiment, when the electric push rod 5 drives the protective cover 401 to cover the reaction vessel 1, the push rod 7 in the reaction vessel 1 will abut the lower end of the embedded tube 601 and drive the embedded tube 601 to move upward until the exhaust hole 607 on the embedded tube 601 is aligned with the exhaust hole 607 on the conduit 403, so that in the process of separating silver by reacting the tungsten-molybdenum raw material with oxalic acid, harmful gases can enter the recovery tank through the conduit 403 for storage. When the protective cover 401 moves upward, the embedded tube 601 will move downward under the drive of the spring 602, so that the exhaust hole 607 on the conduit 403 fits with the rubber ring 606, and the exhaust hole 607 on the embedded tube 601 fits with the outer wall of the conduit 403. At this time, the end of the conduit 403 close to the protective cover 401 is in a closed state, which can effectively prevent the harmful gases from flowing back through the conduit 403 and diffusing from the protective cover 401.

[0037] Embodiment 3

[0038] See also Figure 6 This embodiment further explains the second embodiment. A pin bead 605 is movably embedded inside the limiting straight groove 604, and the pin bead 605 is fixedly embedded on the inner wall of the conduit 403. The limiting straight groove 604 can prevent the embedded tube 601 from detaching from the conduit 403 through the pin bead 605. The pin bead 605 is in movably contact with the embedded tube 601 through the limiting straight groove 604.

[0039] In this embodiment: the pin ball 605 is embedded in the limiting straight groove 604 on the embedded tube 601. During the up and down movement of the embedded tube 601, the rotation of the embedded tube 601 can be prevented to cause the exhaust hole 607 on the embedded tube 601 to be misaligned with the exhaust hole 607 on the conduit 403, and when the embedded tube 601 is separated from the top rod 7, the embedded tube 601 is prevented from being separated from the conduit 403.
