[0002] The main reasons for using cooling and heat exchange equipment in the production of molybdenum oxide are: in the crystallization and precipitation process of molybdenum oxide, the product needs to be separated from the reaction system after the reaction is completed during the production of molybdenum oxide; cooling can reduce the solubility of the product in the solution and promote the crystallization of molybdenum oxide. For example, cooling can crystallize ammonium molybdate in ammonium molybdate solution and improve the product recovery rate; appropriate cooling rate and temperature control are helpful to obtain crystalline products with larger particles and higher purity (cooling of molybdenum oxide reaction solution can reduce the solubility of molybdenum oxide and related products in the solution, making it reach a supersaturated state, thereby promoting the precipitation of molybdenum oxide from the solution in the form of crystals, and realizing the preliminary separation of the product and the solution; for example, in the process of preparing molybdenum oxide from ammonium molybdate solution, ammonium molybdate will crystallize by cooling the solution), which is convenient for subsequent solid-liquid separation and further purification, reducing the impurity content and improving the quality of molybdenum oxide products; When the molybdenum oxide solution is cooled, taking a coil heat exchanger as an example, the contact area between the heat exchange medium and the solution is small, resulting in a low cooling rate of the molybdenum oxide solution and an inability to perform rapid cooling.

[0027] like Figure 1 , Figure 6 and Figure 7 As shown, specific embodiment seven: this embodiment is a further limitation of specific embodiment six, three groups of outer fixed rings 33 are respectively installed on the heat exchange cooling core group 31, the heat exchange cooling core group 31 includes a heat exchange tube body 311, a middle heat exchange tube group 312 and an outer heat exchange tube group 313, the heat exchange tube body 311 is arranged at the center position of the lower cooling jacket 1, and the middle heat exchange tube group 312 is installed on the circumferential outer side of the heat exchange tube body 311, and the middle heat exchange tube group 312 is composed of five groups of equidistantly distributed heat exchange tube bodies 311.

[0028] Working principle: When in actual use, the solution to be cooled is put into the solution inlet pipe 341 and enters the solution inlet box 34. A large number of heat exchange tubes 311 are evenly installed at the bottom of the solution inlet box 34, mainly including a middle heat exchange tube group 312 and an outer heat exchange tube group 313. When the solution flows from top to bottom in the heat exchange tubes 311, the middle heat exchange tube group 312 and the outer heat exchange tube group 313, the heat exchange medium enters the cooling medium inlet pipe. 12, the heat exchange medium includes but is not limited to cooling water and liquid nitrogen; taking cooling water as an example, the cooling water impacts the interior of the lower cooling jacket 1 and the upper cooling jacket 2, and floods a large number of heat exchange tube bodies 311, the middle heat exchange tube group 312, and the outer heat exchange tube group 313, and performs rapid heat exchange and cooling work on the solutions inside the heat exchange tube bodies 311, the middle heat exchange tube group 312, and the outer heat exchange tube group 313; the water bodies are respectively flooded in the heat exchange tube bodies 311, the middle heat exchange tube group 312, and the outer The outer side of the heat exchange tube group 313 can quickly contact the solution flowing inside it for heat exchange; greatly increase the contact area between the solution and the heat dissipation water body; compared with the ordinary straight tube structure, the spiral shape allows the pipe to be arranged longer in a limited box space, so that there is more area for heat exchange between the two fluids, thereby improving the heat exchange efficiency; when the solution flows inside a large number of spiral heat exchange tube bodies 311, the fluid will produce complex flow phenomena such as rotation and secondary flow in the pipe, and the flow state increases the disturbance inside the fluid, reduces the thickness of the boundary layer, and reduces the thermal resistance of heat transfer; the spiral pipe can be arranged in a relatively compact manner in the box, which can make full use of the space inside the box; the compact layout can achieve a higher heat exchange capacity in a smaller space for some places with limited space; the purpose of increasing the contact area between the heat exchange medium and the solution is achieved, the cooling speed of the molybdenum oxide solution is accelerated, and the molybdenum oxide solution is cooled quickly and evenly; Before the molybdenum oxide solution enters the cooling equipment, it will be filtered through the solution inlet pipe 341. Since the molybdenum oxide solution may be mixed with some solid impurities, particles or suspended matter during the production or transportation process, a magnetic filter 3414 is installed inside the filter cylinder 3411 to intercept these impurities before the solution enters the cooling equipment, prevent them from entering the cooling equipment, and avoid impurities from being deposited in the coil and clogging the pipeline, affecting the cooling effect and the normal flow of the solution. A plurality of groups of magnetic bars 34141 are evenly fixed on the circumferential inner wall of the magnetic filter 3414. The magnetic bars 34141 are made of neodymium iron boron material. The NdFeB permanent magnet material has a very high magnetic energy product and coercive force, and can generate a strong magnetic field, which enables it to adsorb ferromagnetic substances and ensure the adsorption effect of metal particles in the solution; it can reduce the probability of wear and tear of coils and related pumps, valves and other equipment caused by the presence of ferromagnetic impurities, increase the service life of equipment, reduce maintenance costs and downtime; it helps to ensure the high quality of molybdenum oxide products, meet the strict requirements of product purity in different application fields, and enhance the market competitiveness of products; the magnetic filter 3414 does not require frequent replacement of filter elements and other consumables, usually only The adsorbed ferromagnetic impurities need to be cleaned regularly; the impurities adsorbed on the magnetic rod 34141 can be cleaned in the following way: the long screw 3417 screwed on the assembly seat 3415 can be removed, and the magnetic filter 3414 can be taken out from the filter cartridge 3411; the magnetic filter 3414 is truncated cone-shaped as a whole, narrow at the top and wide at the bottom; when a fluid such as molybdenum oxide solution enters the truncated cone-shaped magnetic filter 3414, the narrow upper part plays a preliminary flow limiting role, so that the fluid speed is appropriately reduced; as the fluid flows downward, the space gradually widens, and the fluid can be more evenly dispersed in the entire magnetic filter 3414, avoiding Avoid the situation where the local flow rate is too fast or too slow; help to improve the filtration efficiency, so that the ferromagnetic impurities in the fluid can more fully contact with the magnetic rod 34141 in the magnetic filter 3414 and be adsorbed; compared with the cylindrical magnetic filter 3414, the truncated cone structure can better adapt to the flow characteristics of the fluid; when the fluid flows in the gradually widening channel, the pressure change is relatively gentle, thereby reducing the pressure loss caused by sudden changes in pipe diameter or flow obstruction; under the same filtration conditions, the use of the truncated cone magnetic filter 3414 can reduce the pressure requirements for equipment such as fluid delivery pumps, saving energy consumption.

[0029] like Figure 6 As shown, specific embodiment eight: This embodiment is a further limitation of specific embodiment seven, an external heat exchange tube group 313 is installed on the circumferential outer side of the middle heat exchange tube group 312, and the external heat exchange tube group 313 is composed of ten groups of equidistantly distributed heat exchange tube bodies 311; the heat exchange tube bodies 311, the middle heat exchange tube group 312 and the external heat exchange tube group 313 are fixedly connected by an external fixing ring 33, a connecting plate 331 and an internal fixing ring 332.

[0030] like Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, specific embodiment nine: This embodiment is a further limitation of specific embodiment eight, five groups of connecting plates 331 are evenly installed on the circumferential inner wall of the outer fixing ring 33, and the ends of the five groups of connecting plates 331 are respectively fixed on the circumferential outer wall of the inner fixing ring 332, and the connecting plates 331 are arranged in an "S" shape.

[0031] Five groups of positioning strips 32 are evenly installed on the circumferential outer wall of the outer fixing ring 33. The five groups of positioning strips 32 are centrally symmetrical structures about the central axis of the lower cooling jacket 1. The outer fixing ring 33 reinforces the connection of the outer heat exchange tube group 313, and the inner fixing ring 332 reinforces the connection of the middle heat exchange tube group 312.

[0032] When the heat exchange cooling mechanism 3 is installed inside the lower cooling jacket 1 and the upper cooling jacket 2, the heat exchange cooling mechanism 3 is inserted into the five groups of lower positioning grooves 10 and upper positioning grooves 20 on the inner walls of the lower cooling jacket 1 and the upper cooling jacket 2 through five groups of positioning strips 32 evenly arranged on the outside, so that the heat exchange cooling mechanism 3 can be quickly positioned and installed inside the equipment, which is convenient for the heat exchange cooling mechanism 3 to be disassembled as a whole for cleaning; at the same time, the heat exchange tube body 311, the middle heat exchange tube group 312, and the external heat exchange tube group 313 on the heat exchange cooling mechanism 3 are connected and fixed by three groups of outer fixing rings 33 and inner fixing rings 332, so that when the solution is circulated inside the heat exchange tube body 311, the middle heat exchange tube group 312, and the external heat exchange tube group 313, there is no shaking, thereby reducing the decibels of noise generated by the equipment.

[0033] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
