Abstract
The invention relates to the technical field of metal smelting, in particular to a spraying device; the invention aims to solve the technical problem of providing a steel slag pit water fetching device which is not easy to block. Steel slag pit device of fetching water, including spray tube and the spiral-flow body, the entrance at the spray tube is rotationally set up to the spiral-flow body, and the axis collineation of the rotation axis of the spiral-flow body and spray tube.
Description
Technical Field
The invention relates to the technical field of metal smelting, in particular to a spraying device.
Background
In order to improve the water-beating cyclic utilization rate, the hot stuffy water in the steel slag pit needs to be recycled, free calcium ions and sulfate ions are dissolved in the water in the steel slag in the hot stuffy operation process, the solubility of the calcium sulfate dissolved in the water is high under the high-temperature condition, an approximately saturated calcium sulfate solution is formed, the temperature is reduced when the steel slag is conveyed to a spray head station through a slag slurry pump, the calcium sulfate begins to crystallize and separate out, the inner wall of the spray head easily adsorbs the calcium sulfate, and the adsorbed calcium sulfate gradually blocks the spray head outlet.
The existing water fetching device for the steel slag pit only fetches water into the steel slag pit through the spray head, and due to the reasons, the spray head is easy to block, and needs to be stopped to clean calcium sulfate in the spray head or directly replace the spray head, so that the time and labor are wasted.
Disclosure of Invention
The invention aims to solve the technical problem of providing a steel slag pit water fetching device which is not easy to block.
The technical scheme adopted by the invention for solving the technical problems is as follows: steel slag pit device of fetching water, including spray tube and the spiral-flow body, the entrance at the spray tube is rotationally set up to the spiral-flow body, and the axis collineation of the rotation axis of the spiral-flow body and spray tube.
Furthermore, the device also comprises a universal head, and the universal head is communicated with the inlet of the spray pipe.
Further, the universal joint further comprises a valve, and the valve is communicated with the universal head.
Further, the valve is an electrically operated valve.
The invention has the beneficial effects that: steel slag hole device of fetching water, including spray tube and the spiral-flow body, the spiral-flow body rotatably sets up the entrance in the spray tube, the rotation axis of the spiral-flow body and the axis collineation of spray tube, at this device operation in-process, rivers drive the spiral-flow body fast revolution in the spray tube, and the liquid in the spiral-flow body mixs the spray tube for the liquid on spray tube inner wall surface is in the whirl state all the time, and calcium sulfate, sediment grain etc. are difficult for adsorbing at the spray tube inner wall, thereby avoid blockking up the export of spray tube, and the use reliability of this device is higher.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of the nozzle;
FIG. 3 is a structural cross-sectional view of the nozzle;
parts, positions and numbers in the drawings: spray tube 1, cyclone 101, universal head 2, valve 3.
Detailed Description
The invention will be further explained with reference to the drawings.
As shown in fig. 1 to 3, the steel slag pit water-fetching device comprises a spray pipe 1 and a swirling flow body 101, wherein the spray pipe 1 is in a flat duckbill shape, the spray pipe 1 gradually shrinks from an inlet to an outlet, the spray pipe 1 is preferably forged by 20g materials, the swirling flow body 101 is rotatably arranged at the inlet in the spray pipe 1, for example, a shaft is arranged at one end of the swirling flow body 101, a bearing is fixed in the spray pipe 1, the shaft of the swirling flow body 101 is inserted into the bearing, and the shaft is in interference fit with an inner ring of the bearing; a shaft along the axial direction of the spray pipe can be arranged in the cavity of the spray pipe 1, a bearing is arranged in the cyclone body 101, the inner ring of the bearing of the cyclone body 1 is inserted into the shaft on the spray pipe 1, and the shaft is in interference fit with the inner ring of the bearing; the rotational axis of the cyclone body 101 is collinear with the axis of the nozzle 1.
In order to facilitate the spray pipe 1 to spray water in different directions, the invention further comprises a universal head 2, the universal head 2 is communicated with the inlet of the spray pipe 1, water pumped by a slurry pump enters the spray pipe 1 through the universal head 2, and the universal head 2 can rotate in different directions, so that the spray pipe 1 is driven to face in different directions.
In order to control the on-off of the water pumping of the spray pipe 1 conveniently, the invention further comprises a valve 3, the valve 3 is communicated with the universal head 2, and the water pumped by the slurry pump passes through the valve 3, the universal head 2 and the spray pipe 1 in sequence and is finally sprayed out of the spray pipe 1.
In order to facilitate the adjustment of the flow of the spray pipe 1, the valve 3 is an electric valve, and the electric valve can realize remote control, such as an electric ball valve, an electric gate valve, an electric butterfly valve and the like.
