Description
Technical field
The present invention relates to a kind of ammonium nitrate dissolvers, particularly relate to a kind of steam eddy current type ammonium nitrate dissolvers.
Background technology
Usually the dissolving of ammonium nitrate is in a cylinder formula container that has agitating device and Steam Heating chuck or a serpentine coil, to carry out.At first a certain amount of water is put into the dissolving cylinder, stirring next time, gradation or equably ammonium nitrate is added in the entry continuously, the heat that needs is provided through serpentine coil in the container or the outer steam jacket of container by steam indirectly.This process is owing to the contacting inadequately fully of ammonium nitrate and water, steam heat discharge reasons such as difficulty, caused that dissolution velocity is slow, capacity usage ratio is low, the discontinuous shortcoming of course of dissolution.In the prior art, effective measures can not eradicated above-mentioned defective.
Summary of the invention
The present invention provides a kind of steam eddy current type ammonium nitrate dissolvers with higher dissolved efficiency for solving the deficiency of prior art.
The scheme that solves technical problem of the present invention is: steam eddy current type ammonium nitrate dissolvers is made up of button, sealing ring, obturating cup, steam drum, resistance power line, thermal baffle, sieve spherical shell, sieve ball handle, pedestal, spring, seal washer, sealing ring, motor power-supply wire, machine shaft, motor, nozzle, heating resistor, taphole, water storage space, dissolving space, mezzanine space and deflating valve.
Steam drum is the double Shell that columnar, upper end closed, lower end open wide.Steam drum has a mezzanine space, and the cylindrical space quilt in the steam drum is that holistic, horizontally disposed thermal baffle is divided into the water storage space on top and the dissolving space of bottom with steam drum.All there is vertical through hole the center of the inside and outside shell at steam drum top; Columniform button runs through said two through hole; The top of button have one with button be holistic, diameter oblate cylinder greater than the diameter of button; The bottom of button is in the water storage space; The bottom of button has the obturating cup of oblate cylindricality, and along locating all to be bonded with sealing ring, there is a deflating valve hollow, reverse frustoconic the lower edge of the said through hole at steam drum inner casing top at the bottom of the said through hole of the upper surface of obturating cup and steam drum top enclosure body.On the button between the oblate cylinder on the cover top portion of steam drum and button top, be with spring.Heating resistor is in the water storage space, and the resistance power line that is connected with heating resistor passes from the cable channel that is positioned at the steam drum sidewall.Pedestal is the cylindrical tube that the upper end opens wide, and is provided with motor in the bottom of pedestal, and the motor power-supply wire that links to each other with motor stretches out from the sidewall of pedestal.Taphole that communicate with base interior, horizontally disposed is installed on the sidewall of pedestal.The machine shaft of motor upwards stretches out from the center on base bottom plane, and the junction, bottom of machine shaft and pedestal is provided with sealing ring.The upper end of machine shaft is with the sieve ball handle that becomes the tight fit relation with machine shaft, and the upper end of sieve ball handle is and the as a whole sieve spherical shell of sieve ball handle that the sieve spherical shell is the spherical shell netted, that the top opens wide, and in the sieve spherical shell ammonium nitrate crystals is housed.The perforation size of said net is less than the size of the ammonium nitrate crystals in the sieve spherical shell.The lower surface of steam drum is bonded with the seal washer of annular; The lower end of steam drum is inserted in the suitable for reading interior of pedestal and combines with screw thread with pedestal; Nozzle is the horizontally disposed straight tube that is positioned at the dissolving space; One end of nozzle is connected with the inner casing of steam drum and communicates with mezzanine space, and the other end of nozzle is opened wide.That a plurality of equal heights are provided with, constitute a nozzle layer along the equally distributed nozzle of steam drum inner casing inwall, a plurality of nozzle layers vertically are uniformly distributed in the dissolving space.The sieve spherical shell is in the horizontal centre position of each described nozzle layer.The axial line of each root nozzle is tangent with the excircle of the horizontal section circle of the sieve spherical shell of place height, and the end of opening wide of each root nozzle points to the direction opposite with direction of motor rotation.
During operation; Connect the power supply of heating resistor earlier; The heating of heating resistor makes the water boiling in the water storage space and in water storage space, produces high steam, opens the power supply of motor again, when driven by motor sieve spherical shell rotates at a high speed; Under centrifugal action, the ammonium nitrate crystals in the sieve spherical shell is uniformly distributed in the inwall of sieve spherical shell.At last button is pressed; When the sealing ring of obturating cup upper surface separates with deflating valve; Deflating valve is opened; High steam goes out and sees through the eyelet that sieves spherical shell to inject in the sieve spherical shell from the opening wide the end high velocity jet of each nozzle after getting into mezzanine space, and the ammonium nitrate crystals in the sieve spherical shell is met the cold condensed water that produces by steam rapidly and dissolved, and the ammonium nitrate dissolving of production imports the inner bottom surface of pedestal and flows out from taphole.
Adopt such scheme, compared with prior art, the present invention has following marked improvement:
1. because the axial line of each root nozzle is tangent with the excircle of the horizontal section circle of the sieve spherical shell of place height; And the direction of opening wide end sensing and motor and sieve spherical shell direction of rotation of each root nozzle; Therefore; The steam that ejects in many nozzles has formed a steam whirlpool of rotation at a high speed in the dissolving space, the inboard of whirlpool with sieve spherical shell and contact.And sieving spherical shell in this whirlpool high speed backward rotation, this is steam jet velocity and the linear velocity sum of sieving the spherical shell rotation with regard to the contact velocity that makes ammonium nitrate crystals and steam.Directly compare with existing,, thereby promoted dissolved efficiency significantly because the present invention has improved the contact velocity of steam and ammonium nitrate greatly through the technical scheme of steam dissolving ammonium nitrate.
2. because the present invention has adopted the sieve spherical shell of spherical shell shape to place ammonium nitrate crystals; When rotating at a high speed; Ammonium nitrate crystals is uniformly distributed in the inwall of sieve spherical shell, and a plurality of nozzle layer vertically is uniformly distributed in the dissolving space, and this just makes that the contact area of steam and ammonium nitrate crystals is the spherical shell area; Be far longer than in the existing direct technology and adopt pencil steam and the contacted scheme of pencil ammonium nitrate crystals, thereby promoted dissolved efficiency significantly through steam dissolving ammonium nitrate.
3. the sieve spherical shell can either guarantee that steam gets into smoothly and contacts with ammonium nitrate crystals in the housing; Can avoid ammonium nitrate crystals to sputter housing again; Simultaneously, the ammonium nitrate solution of dissolving can flow out from housing sidewall again, and above-mentioned two beneficial effects that play for the present invention like this provide assurance.
