[0002] Ammonium tetramolybdate is the basic raw material for producing high-purity molybdenum trioxide, metallic molybdenum powder and other molybdenum deep-processing products. Ammonium tetramolybdate is produced by acid precipitation of ammonium molybdate solution. The insoluble matter content in the ammonium molybdate solution directly affects the quality of the ammonium tetramolybdate product. At present, the aging method is generally used in the industrial production process of ammonium tetramolybdate to reduce the insoluble matter in the ammonium molybdate solution.

[0003] During the aging process, in order to enhance the aging effect, additives such as flocculants are often added to improve the aging efficiency. At present, the addition of materials to the aging tank is mainly done manually from the feeding port or by injection.

DETAILED DESCRIPTION

[0020] 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 in 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.

[0021] See also Figure 1-3 The utility model provides an implementation scheme: in the aging process of ammonium molybdate solution, in order to improve the aging efficiency, auxiliary additives need to be added. At present, the additives are mostly added directly through the feeding port. However, this adding method is often limited to one point, so it is not easy to mix with the aged ammonium molybdate solution, which easily causes uneven mixing and affects the efficiency and quality of aging.

[0022] In view of the above problems, the present application discloses a quantitative feeding mechanism for an ammonium molybdate solution aging tank. The device uses an aging tank body 1 as a container, and adds an ammonium molybdate solution into the aging tank body 1. A top cover 2 is provided at the top of the aging tank body 1, and the top opening of the aging tank body 1 is sealed by the top cover 2. An adding sleeve 3 is installed on the top cover 2, and an additive is mixed with the ammonium molybdate stock solution by the adding sleeve 3. An adding component 4 is provided in the adding sleeve 3, and the ammonium molybdate stock solution mixed with the additive is added into the aging tank body 1 by the adding component 4.

[0023] Specifically, the above-mentioned adding component 4 is composed of a push-injection mixer 41, a stock solution inlet pipe 42 and a split flow discharger 43;

[0024] According to the instruction manual Figure 1-3 It can be seen that the push-in mixer includes a mixing shaft 411 axially arranged in the adding sleeve 3, a mixing blade 412 sleeved on the mixing shaft 411, a mixing motor 413 connected to the end of the mixing shaft 411, and a plunger-type doser 44 connected to the adding sleeve 3. The mixing motor 413 drives the mixing shaft 411 to rotate, and then the mixing shaft 411 drives the mixing blade 412 to rotate, so that the mixing blade 412 mixes the additive added by the plunger-type doser 44 and the sodium molybdate solution entering from the stock solution inlet pipe 42, and then the sodium molybdate solution mixed with the additive is uniformly dispersed and added to the aging tank through the diverter excluder to improve the mixing uniformity;

[0025] According to the instruction manual Figure 1-3It can be known that the above-mentioned flow splitter and discharger 43 includes a push injection main pipe 431, which is connected to the addition sleeve, and a push injection pump 432 is provided on the push injection main pipe 431. A plurality of flow splitters 433 are connected to the push injection main pipe 431, and the plurality of flow splitters 433 penetrate the top cover 2 and are inserted into the aging tank body 1; in the specific implementation process, the push injection pump 432 is used as a power to make the push injection main pipe 431 extract the mixed stock solution from the addition sleeve, and the push injection main pipe 431 is connected with the addition sleeve, so that the mixed stock solution is uniformly mixed from the push injection main pipe 431 into the plurality of flow splitters 433 for splitting;

[0026] The aging tank body 1 is connected to a raw liquid delivery pipe 5, on which a shunt control joint 6 is provided to communicate with a raw liquid inlet pipe 42, which is connected with the adding sleeve 3. The raw liquid delivery pipe 5 is used to add ammonium molybdate solution into the aging tank body 1. The shunt control joint 6 can be used to switch the raw liquid delivery pipe 5 and the raw liquid inlet pipe 42 to supply ammonium molybdate solution to the adding sleeve 3 and the aging tank, respectively.

[0027] As a preferred solution, further, the aging tank body 1 is a cylindrical kettle body, and the top cover 2 is separately connected to the aging tank body 1 through a hinge, so as to facilitate opening the aging tank for cleaning and maintenance.

[0028] As a preferred solution, further, according to the attached description Figure 1-3 It can be known that the above-mentioned injection main pipe 431 is connected to several diversion tubes 433 through a diverter 434. The diverter 434 is a trough body with a partial conical structure. The cavity part structure in the diverter 434 is a partial conical groove and is respectively connected to the injection main pipe 431 and several diversion tubes 433. Through the diversion effect of the diverter 434, the mixed liquid can be guided and diverted, so that the mixed liquid can be evenly diverted into several diversion tubes 433.

[0029] As a preferred solution, further, the plunger-type doser 44 is a syringe-type structure and is provided with an electric push rod to control the movement of the plunger. The electric push rod controls the movement of the plunger to push the additive in the plunger-type doser 44 into the addition sleeve.

[0030] As a preferred solution, further, a plurality of one-way valves are provided on the plurality of shunt pipes 433 , and a control valve 435 is provided on the push injection main pipe 431 , and the control valve 435 on the push injection main pipe 431 can control the connection between the push injection main pipe 431 and the adding sleeve 3 .

[0031] As a preferred solution, further, the stock solution inlet pipe 42 is connected to the diversion control joint 6 through a threaded joint and a check valve 421 is provided between the stock solution inlet pipe 42 and the addition sleeve 3 to prevent the ammonium molybdate solution and the additive from returning to the stock solution inlet pipe 42 due to pressure during the injection process of the plunger doser 44.

[0032] From the above, it can be generally known that the quantitative feeding mechanism of the ammonium molybdate solution aging tank performs quantitative feeding through the quantitative plunger feeder 44 when feeding the aging tank, and mixes the ammonium molybdate solution entering the stock solution inlet pipe 42 with the medicine through the adding component 4, so that the ammonium molybdate solution carries the additive through the diverter 434 and is evenly filled into the aging tank, thereby improving the uniformity of aging and improving the aging effect and efficiency.
