Description
Technical Field
The utility model belongs to the technical field of metallurgical equipment, more specifically the lime jetting device that relates to a zinc is smelted in oxidation that says so.
Background
In a zinc smelting oxidation smoke dust wet method system, due to process characteristics, lime is required to be added in a neutralization section for iron removal, dry lime is added with water and slurried into lime milk in the prior art, but a large amount of water is supplemented into the system flow in the slurrying process, so that the flow volume is expanded, and great disadvantages are caused to wet production. The preparation of lime milk needs manual bag making, a belt feeder, stirring and slurrying, a conveying pump and other equipment, and a large amount of manpower and material resources need to be wasted.
SUMMERY OF THE UTILITY MODEL
In order to overcome the problem that exists among the background art, the utility model provides a lime jetting device for oxidizing neutralization zinc is smelted jets slaked lime powder to jar in through air conveying pump, through adjustment jetting pressure, and volume expansion is avoided to control jetting feed size, reduces neutralization technology manpower and materials.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: the utility model provides a lime jetting device for oxidizing and zinc smelting, stores up cabinet, pneumatic conveyor pump, pneumatic conveyor pipeline, nozzle, ejection of compact pipeline, charge-in pipeline, pH detector, PLC controller including jar body, slaked lime, jar body top be provided with slaked lime and store up the cabinet, jar body upper end is provided with charge-in pipeline, slaked lime stores up the cabinet and is connected with pneumatic conveyor pump, jar body lower extreme annular is evenly provided with the nozzle at an interval, the nozzle passes through pneumatic conveyor pipeline and is connected with pneumatic conveyor pump, jar body bottom surface is provided with ejection of compact pipeline, is provided with the pH detector in the ejection of compact pipeline, PLC controller and pneumatic conveyor pump, pH detector be connected.
Furthermore, a pressure gauge is arranged on the pneumatic conveying pipeline and connected with the PLC.
The utility model discloses beneficial effect: carry lime hydrate to the shower nozzle through pneumatic conveying pump, the shower nozzle annular sets up in jar body bottom, and lime hydrate and feed liquid intensive mixing during jetting lime hydrate make lime hydrate and feed liquid misce bene, improve mixing rate, are provided with the pH detector on the ejection of compact pipeline, through detecting out material pipeline feed liquid pH value automatic control pneumatic conveying pump feed rate, realize full automated production, reduce manpower and materials extravagant.

FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a circuit diagram of the present invention.
In the figure, 1-tank body, 2-slaked lime storage cabinet, 3-pneumatic conveying pump, 4-pneumatic conveying pipeline, 5-nozzle, 6-discharging pipeline, 7-feeding pipeline, 8-pH detector, 9-pressure gauge and 10-PLC controller.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in fig. 1-2, a lime blowing device for oxidation neutralization zinc smelting comprises a tank body 1, a slaked lime storage cabinet 2, a pneumatic conveying pump 3, a pneumatic conveying pipeline 4, a nozzle 5, a discharging pipeline 6, a feeding pipeline 7, a pH detector 8 and a PLC (programmable logic controller) 10, wherein the slaked lime storage cabinet 2 and the slaked lime storage cabinet 2 are arranged above the tank body 1, slaked lime powder is transported by a filling vehicle, and the lime powder is directly conveyed into the slaked lime storage cabinet by the conveying pump of the vehicle. The upper end of the tank body 1 is provided with a feeding pipeline 7, feed liquid to be reflected is injected into the tank body 1 through the feeding pipeline 7, the slaked lime storage cabinet 2 is connected with the pneumatic conveying pump 3, nozzles 5 are annularly and uniformly arranged at the lower end of the tank body 1 at intervals, the nozzles 5 are connected with the pneumatic conveying pump 3 through the pneumatic conveying pipeline 4, the nozzles 5 directly inject slaked lime into the bottom of the tank body 1, if slaked lime is injected from the top surface, the slaked lime can suspend in the feed liquid on the top surface, the reaction is slow, the slaked lime and the feed liquid are not uniformly mixed, slaked lime is injected through the bottom surface, the contact area of the slaked lime and the feed liquid is increased, the reaction rate is improved, and the feed liquid is uniformly mixed. The bottom surface of the tank body 1 is provided with a discharge pipeline 6, a pH detector 8 is arranged in the discharge pipeline 6, the pH detector 8 is connected with the input end of a PLC (programmable logic controller) 10, the output end of the PLC 10 is connected with the control signal end of a pneumatic conveying pump 3, the PLC 10 controls the conveying capacity of slaked lime of the pneumatic conveying pump 3 according to the pH value of the feed liquid in the discharge pipeline 6, the pH value of the discharge feed liquid is accurately regulated and controlled, and the oxidation neutralization zinc smelting process quality is improved.
Further, 4 say and be provided with manometer 9 on the pneumatic conveyor pipe, manometer 9 be connected with PLC controller 10, detect 4 pipeline pressure of pneumatic conveyor pipe in 3 transportation process of pneumatic conveyor pump, when detecting that pipeline pressure risees unusually, PLC controller 10 reduces 3 transmission power of pneumatic conveyor pump or stops the work of pneumatic conveyor pump 3, effectively prevents the putty.
Finally, it is noted that the above preferred embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit, although the present invention has been described in detail through the above preferred embodiments, it should be understood by those skilled in the art that various changes in form and detail may be made thereto without departing from the scope of the present invention.
