All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.
Referring to fig. 1-3, the present utility model provides a technical solution:
A low-grade phosphate rock powder recycling device comprises a dust removal barrel 101, wherein the lower end of the dust removal barrel 101 is communicated with an air inlet pipe 201, the top of the dust removal barrel 101 is communicated with an air outlet pipe A301, a filtering device, a primary cleaning device and a secondary cleaning device are sequentially arranged in the dust removal barrel 101 from bottom to top, the primary cleaning device comprises an annular pipe A401 connected with the dust removal barrel 101 and a plurality of cleaning units arranged on the annular pipe A401, the annular pipe A401 is communicated with the air inlet pipe 201, dust-containing gas flowing into the annular pipe A401 can flow into any cleaning unit, the dust-containing gas cleaned by the cleaning units flows to the secondary cleaning device, and solid-liquid mixture generated by cleaning of the cleaning units flows to the filtering device for solid-liquid separation.
Specifically, the arbitrary cleaning unit comprises an exhaust pipe B402 communicated with an annular pipe A401 and a liquid storage pipe 403 arranged on the exhaust pipe B402, the liquid storage pipe 403 wraps an exhaust section of the exhaust pipe B402, a plurality of exhaust holes 404 are formed in the exhaust section of the exhaust pipe B402, the top end of the liquid storage pipe 403 is open and is in a horn-shaped structure, and a plurality of water dripping holes 405 are formed in the bottom of the liquid storage pipe 403. The exhaust pipe B402 communicates with an external dust collecting device, and when dust needs to be treated, the dust collecting device feeds dust containing ore powder into the annular pipe a401 through the intake pipe 201 at a certain pressure.
In order to separate out the solid particles in the solid-liquid mixture for recycling, a filtering device is specially designed at the inner bottom of the dust removing barrel 101. The filtering device comprises a filtering barrel 601 positioned below an annular pipe A401, the top end of the filtering barrel 601 is of a conical structure, a plurality of filtering holes 602 are formed in the top of the filtering barrel 601, gaps exist between the outer side wall of the filtering barrel 601 and the inner side wall of the dedusting barrel 101, a sewage outlet 701 is formed in the bottom of the dedusting barrel 101, a drain pipe 702 is arranged in the bottom of the dedusting barrel 101, and the drain pipe 702 is communicated with the filtering barrel 601.
After the solid-liquid mixture flowing out of the cleaning unit flows to the upper surface of the filter tank 601, if the solid particles therein are excessively accumulated on the upper surface of the filter tank 601, on one hand, the filter holes 602 are blocked, and on the other hand, the accumulated solid particles cannot fall into the bottom of the dust removal tank 101 to be discharged, so that the recycling rate of the solid particles is reduced. Therefore, the specially designed scraping device comprises a driving motor 801 arranged at the bottom of the dust removal barrel 101, a rotating shaft 802 rotationally connected with the filter barrel 601, and a scraping plate 803 always in an abutting state with the outer top wall of the filter barrel 601, wherein the central axis of the rotating shaft 802 is collinear with the central axis of the filter barrel 601 and is in transmission connection with the driving motor 801, and one end of the rotating shaft 802 far away from the driving motor 801 extends out of the top of the filter barrel 601 and then is connected with the scraping plate 803.
If the water in the reservoir 403 is not able to completely submerge the exhaust section of the exhaust pipe B402 at some time, it may cause part of the dust-laden gas exhausted through the exhaust pipe B402 to flow directly out of the top of the reservoir 403. In this case, the dust-containing gas needs to be treated, so that the secondary cleaning device is specially designed at the inner top of the dust-removing barrel 101, and comprises a water inlet pipe 901, an annular pipe B902 communicated with the water inlet pipe 901, and a plurality of spray nozzles 903 communicated with the annular pipe B902, wherein the water inlet pipe 901 is arranged in the dust-removing barrel 101 in a penetrating manner, and the water inlet pipe 901 can be connected with a pumping mechanism matched with the outside for use, so that water can be conveniently injected into the annular pipe B902. The annular pipe B902 is arranged in the dust removing barrel 101 and above the annular pipe A401, and the spray nozzles 903 are in one-to-one correspondence with the liquid storage pipes 403.
Working principle:
When the dust-containing gas containing ore powder is treated, the dust collecting device is first caused to send the dust-containing gas into the annular pipe a401 through the air inlet pipe 201 at a certain pressure, and the dust-containing gas flows into the liquid storage pipe 403 through the plurality of air outlet holes 404 on the air outlet pipe B402. Simultaneously, the annular pipe B902 is filled with water, the water is sprayed out through each spray nozzle 903, and the top opening of each liquid storage pipe 403 is covered by water mist sprayed out by each spray nozzle 903.
Water is then continuously injected into each of the reservoirs 403 such that it completely floods the exhaust section of the exhaust pipe B402. The dust-containing gas with a certain pressure can enter the water in the liquid storage pipe 403 under the action of the pressure, and solid particles in the dust-containing gas can remain in the water to settle towards the bottom of the liquid storage pipe 403, so that the solid-liquid mixture formed in the process falls to the top of the filter tank 601 through the water dropping hole 405. The dust-containing gas filtered by the water in the liquid storage pipe 403 flows upward through the opening of the liquid storage pipe 403, is washed by the water mist generated by the spray nozzle 903 for the second time, and is finally discharged through the exhaust pipe a 301. In this process, because air pressure exists in the exhaust pipe B402, water in the liquid storage pipe 403 cannot enter the exhaust pipe B402 through the exhaust hole 404 (for example, drinking by a straw in daily life, one end of the straw extends into the beverage, the other end of the straw is contained in the mouth, then the mouth continuously blows air into the straw, and in this process, air blown out from the mouth can enter the beverage through the straw, so long as the air blowing is not stopped, the beverage cannot enter the straw).
When the solid-liquid mixture generated in the cleaning process falls to the top of the filter tank 601, the liquid therein flows into the filter tank 601 through the filter holes 602 and is discharged through the drain pipe 702, the solid particles therein stay on the outer top wall of the filter tank 601, at this time, the driving motor 801 is started, the scraper 803 moves circumferentially around the central axis of the rotating shaft 802, and the scraper 803 is always in contact with the filter tank 601 in the rotating process, so that the solid particles are scraped to the bottom of the dust removal tank 101, and the solid particles containing water are discharged into a matched collection box through the drain 701 for recycling.
When all the dust-containing gases are treated, the water pumping mechanism connected with the water inlet pipe 901 stops pumping water to the annular pipe B902, and simultaneously stops injecting water into each liquid storage pipe 403, but the dust collecting equipment still continues to work, and clean air is continuously injected into the exhaust pipe B402, so that air pressure is always present in the exhaust pipe B402, and water in the liquid storage pipes 403 is prevented from flowing into the air inlet pipe 201 through the exhaust holes 404, the exhaust pipe B402 and the annular pipe A401 in sequence. When the water in the liquid storage pipe 403 leaks out through the water drop hole 405, the dust collecting device stops working, namely the cleaning and recycling work of the dust-containing gas is completed.
The foregoing is merely a preferred embodiment of the utility model, and it is to be understood that the utility model is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art. And that modifications and variations which do not depart from the spirit and scope of the utility model are intended to be within the scope of the appended claims.
