Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, and described embodiment is only the present invention's part embodiment, is not whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments used obtained under creative work prerequisite, belongs to protection scope of the present invention.
By reference to the accompanying drawings, effective cold slag of the present invention, comprise base 11, described base 11 is provided with cold slag cylinder 12, the front-end and back-end of described cold slag cylinder 12 are respectively equipped with front backing ring 13 and rear backing ring 16, front backing ring 13 and rear backing ring 16 are equipped with installation front riding wheel apparatus 18 on the pedestal 11 and rear riding wheel apparatus 17 respectively, and the outer wall of the cold slag cylinder 12 between front backing ring 13 and rear backing ring 16 is provided with gear ring 14, and described gear ring 14 engages with drive unit 15; The feed end of cold slag cylinder 12 of the present invention is also equipped with feed pipe 19, and those skilled in the art understands and understands, and does not repeat them here.Described cold slag cylinder 12 comprises inner core 7 and urceolus 1, described urceolus 1 is set in the periphery of inner core 7 and forms cavity, described urceolus 1 offers cooling water inlet 9 and coolant outlet 10, cooling water inlet+and coolant outlet 10 are for the circulation of cooling fluid, described cooling water inlet 9 and coolant outlet 10 and cavity connects, the inwall of described inner core 7 is provided with spiral flow deflector 8, spiral flow deflector 8 is for the propelling of slag charge, middle cylinder 4 is provided with between described inner core 7 and urceolus 1, that is to say that cylinder 4 is arranged in cavity, the vapor chamber 6 of vacuum is formed between described middle cylinder 4 and inner core 7, the inwall of described vapor chamber 6 is provided with liquid-sucking core 5, hydraulic fluid is provided with in described vapor chamber 6.The present invention, by arranging heat pipe-type structure between inner core and urceolus, can improve heat transference efficiency; The uniformity of axial temperature can be improved simultaneously, ensure that cooling water can be fully used, and radiating effect will be caused inconsistent because section temperature before and after cold slag cylinder is inconsistent, improve the effect of cooling.
As the mode of a kind of selection of the present invention, inner core and middle cylinder are made up of 4Cr5MoSiV steel, and hydraulic fluid is water.Working range of the present invention is normal temperature (0 °-250 °), the melting temperature of hydraulic fluid must lower than the operating temperature of heat pipe, critical point temperature then must higher than the operating temperature of heat pipe, consider simultaneously hydraulic fluid must with housing and liquid-sucking core material compatible, there is the larger factor that transports and heat conduction factor, stablize good thermophysical property and economy, therefore the present invention selects excellent water as hydraulic fluid; And inner core and urceolus are made up of 4Cr5MoSiV steel, due to needs continuous firing, strength and stiffness in use must be ensured; Have simultaneously lower roughness and good can polishability and welding performance, the selection of material of the present invention, hydraulic fluid can ensure to have good economy, heat transference efficiency and service life.The material of heat of the present invention, the selection of hydraulic fluid are very complicated processes, for a person skilled in the art, are not apparent.
Liquid-sucking core of the present invention is copperly roll silk screen liquid-sucking core, and the material inhaling liquid-sucking core is compatible with inner core, middle cylinder material and hydraulic fluid; Require that liquid-sucking core has very little effective capillary radius, to provide maximum capillary pressure; Larger permeability K value, to reduce the pressure loss of withdrawing fluid; Less thermal conduction resistance, to reduce radial guiding resistance to heat, therefore selects liquid-sucking core to be a very complicated process, also needs to consider manufacture difficulty, considering therefore through each side simultaneously, and liquid-sucking core of the present invention is selected and copperly rolled silk screen liquid-sucking core.
Liquid-sucking core of the present invention is order number, and to be that 60-300 objects are copper roll silk screen liquid-sucking core, liquid-sucking core liquid flowing resistance be inversely proportional to Wang Yan size square, and the pressure that liquid-sucking core produces is inversely proportional to mesh size.In actual application, when liquid-sucking core order number is greater than 300, rigidity can be caused not enough; When liquid-sucking core order number is less than 50, the capillary pressure of generation is stable not again, and show through repeatedly testing, the maximum capillary pressure that liquid-sucking core produces is at least about 2 times of fluid column static pressure, ability steady operation; Consider, the present invention selects order number to be that 60-150 objects are copper and rolls silk screen liquid-sucking core, and wherein the copper silk screen liquid-sucking core that rolls belongs to prior art products, and those skilled in the art understands and understands, and does not repeat them here.
As a kind of preferred mode of the present invention, be connected with conducting strip 2 between the outer wall of described middle cylinder 4 and the inwall of urceolus 1, the area dispelled the heat with raising in limit, strengthen the exchange of heat and cooling water, improve the effect of heat radiation.
As a kind of preferred mode of the present invention, what conducting strip 2 tilted is connected between middle cylinder 4 and urceolus 1.
Conducting strip 2 of the present invention offers cooling water through hole 3, improves heat exchange area further, improve the efficiency of heat radiation.
