Description
Technical field
The utility model relates to a kind of reducing mechanism, is specially magnetic material, particularly the hydrogen reducing mechanism of neodymium-iron-boron magnetic material.
Background technology
Rare earth transition metal magnetic material, particularly neodymium-iron-boron magnetic material have invertibity and inhale the characteristic of putting hydrogen and disproportionation decomposition.Under certain hydrogen pressure, magnetic material low temperature is inhaled hydrogen generation efflorescence behavior, and middle temperature is inhaled the behavior of hydrogen generation disproportionation, then keeps the structure of former compound constant behind the high-temperature dehydrogenation.Utilize the above-mentioned characteristic of rare earth metal magnetic material, can be made into the hydrogen reducing mechanism of magnetic material.Existing magnetic material hydrogen reducing mechanism, processes such as the efflorescence of low temperature suction hydrogen, middle temperature suction hydrogen disproportionation, high-temperature dehydrogenation and cooling are all finished in single container, and this container needs input pressure hydrogen a little while, extracts hydrogen out a little while, heat a little while, cooling a little while, like this, not only structure, the performance to apparatus container has strict demand, and each operation can not be carried out simultaneously, because the inertia of vessel temp, pressure, the inefficiency that device hydrogen is pulverized is unfavorable for continuous production.
Summary of the invention
The utility model solves existing hydrogen reducing mechanism can not the quantity-produced problem, the magnetic material hydrogen reducing mechanism that provides a kind of each operation can be simultaneously, carry out continuously.
The utility model is to adopt following technical scheme to realize: magnetic material hydrogen reducing mechanism, comprise the suction hydrogen pulverization cylinder that has electric heater unit, the skin of inhaling the hydrogen pulverization cylinder is provided with water jacket, the bottom of inhaling the hydrogen pulverization cylinder links by valve and the dehydrogenation tube that has electric heater unit, the dehydrogenation tube bottom is fixed with valve, and dehydrogenation tube bottom is provided with the cooling cylinder with the activity of dehydrogenation tube bottom valve, sealed attachment.Dehydrogenation tube bottom valve can be fixed by cylindrical shell direct with bolt and the dehydrogenation tube.Cooling cylinder can rely between the two pressure realization activity, sealed attachment by an auxiliary last moving mechanism with cooling cylinder and dehydrogenation tube bottom valve dieback.This device is finished the container separately of the pulverizing of suction hydrogen, high-temperature dehydrogenation, refrigerating work procedure by setting and by valve it is coupled to each other, form and press the vertical structure that process sequence is arranged, the control respective valves, magnetic material enters in the cylindrical shell of each operation successively, each operation is finished in the container separately, realize that each operation carries out simultaneously, and then reach device quantity-produced purpose.
Inhale the electric heater unit of hydrogen pulverization cylinder, dehydrogenation tube, can adopt built-in or the external electric heating device, built-in structure is with electric heating element---electrically heated rod places tube inner chamber, and outlet structure is with electric heating element---, and resistive heater is wrapped in outside the cylindrical shell.The structure of heater can be selected as required.
The utility model is inhaled the valve of hydrogen pulverization cylinder, dehydrogenation tube bottom can adopt butterfly valve or slide valve.
Because the operating temperature of dehydrogenation tube is higher, cooling cylinder, inhale hydrogen pulverize by the valve tube directly and the dehydrogenation tube link, the dehydrogenation tube can be directly to cooling cylinder, suction hydrogen pulverization cylinder conduction heat, simultaneously, structure to cooling cylinder, suction hydrogen pulverization cylinder, particularly the valve on the cooling cylinder and the hear resistance of inhaling the valve between hydrogen pulverization cylinder and dehydrogenation tube have higher requirement, even this valve need adopt the high temperature resistant valve of special use, thereby can increase the manufacturing cost of cooling cylinder and whole device.For this reason, between suction hydrogen pulverization cylinder and dehydrogenation tube, have additional heat insulation cylindrical shell, heat insulation cylindrical shell links with inhaling hydrogen pulverization cylinder and dehydrogenation tube respectively through valve up and down, and the dehydrogenation tube links by its bottom valve and heat insulation cylindrical shell, movable, the sealed attachment of cooling cylinder and heat insulation cylindrical shell bottom.
Magnetic material hydrogen reducing mechanism described in the utility model, suction hydrogen, dehydrogenation, refrigerating work procedure that magnetic material hydrogen is pulverized are finished in different containers simultaneously, and adopt the vertical structure that is coupled to each other by valve between each container, be convenient to the transmission of each inter process of magnetic material, also make the hydrogen reducing mechanism realize producing continuously, improve the efficient that device is produced.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
Magnetic material hydrogen reducing mechanism, comprise the suction hydrogen pulverization cylinder 1 that has electric heater unit, suction hydrogen pulverization cylinder has the loam cake 11 of sealed attachment and takes out, the mouth of pipe 12 of inflation body, the skin of inhaling the hydrogen pulverization cylinder is provided with water jacket 2, communicate with water jacket and to be provided with into, effluent pipe mouth, the electric heater unit of inhaling the hydrogen pulverization cylinder adopts electrically heated rod 7 to be fixed in the built-in structure of tube inner chamber, the bottom of inhaling the hydrogen pulverization cylinder links by valve 3 and heat insulation cylindrical shell 20, the bottom of heat insulation cylindrical shell links by valve 21 and the dehydrogenation tube 4 that has electric heater unit, the electric heater unit of dehydrogenation tube adopts resistive heater 10 to be wrapped in the outer outlet structure of cylindrical shell, the dehydrogenation tube is provided with to be taken out, aerating pipe port 13, the dehydrogenation tube bottom links by valve 5 and heat insulation cylindrical shell 8, cooling cylinder 6 and heat insulation cylindrical shell activity, sealed attachment.Valve 3,21,5 between each cylindrical shell all adopts butterfly valve, and be convenient fixing the employing to the folder butterfly valve, the end that is coupled to each other of each cylindrical shell is all managed orchid, will be clamped between the flange of cylindrical shell the folder butterfly valve with bolt, thereby realize connecting between each cylindrical shell and valve and cylindrical shell.Routinely, cooling cylinder 6 upper ends are provided with valve, are used for the switching of cooling cylinder, because the existence of heat insulation cylindrical shell 8, the valve on the cooling cylinder can adopt the common butterfly valve of nonrefractory structure, also be provided with on the cooling cylinder take out, aerating pipe port 14.Be to accelerate the cooling of cooling cylinder, be provided with water jacket 9,, accelerate the cooling of magnetic material in the cooling cylinder by the circulation of cooling water in the water jacket at the skin of cooling cylinder.Heat insulation cylindrical shell 8,20 also is provided with water jacket, increases the effect of heat insulation of heat insulation cylindrical shell.All water jackets in this device all have the water-in and water-out mouth of pipe, make the water circulation in the water jacket.
