The specific embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish label is represented components identical.Be used to explain the utility model below by the embodiment that is described with reference to the drawings, described embodiment is exemplary, and can not be interpreted as restriction of the present utility model.
Referring to Fig. 1, Fig. 2, Fig. 4 and Fig. 5, according to the nozzle that is used for the sand storehouse of the utility model embodiment, comprise spout 1 and sealing cover body 2, described spout 1 is formed on the bulkhead 3 in sand storehouse 30 with connecting; Described cover body 2 is fastened on described spout 1 place and is installed on the outer wall in sand storehouse 30, and described cover body 2 is formed with and is suitable for the connecting portion 21 that is connected with the outer pipeline 5 in sand storehouse 30, the inner chamber of described cover body 2 is by the intracavity inter-connection of described spout 1 with sand storehouse 30, thereby to the inner chamber jet fluid in sand storehouse.
On the described pipeline 5 non-return valve 4 is installed, when fluid is opened non-return valve 4 in the pipeline 5, fluid in the pipeline 5 sprays in the sand storehouse by spout 1, precipitation material in the sand storehouse is produced impact (even the fluidization of material in the sand storehouse), thereby being beneficial to these materials emits from the sand storehouse smoothly, in addition, non-return valve 4 prevents fluid countercurrent current.
Need to prove that the fluid in the pipeline 5 can be water, gas, the perhaps gentle compound of water.The flow of high pressure water or gas and pressure can be controlled according to the concentration of material in the sand storehouse and the stability of flow, make that the material concentration in the sand storehouse is consistent all the time, and flow is more stable.
Compared with prior art, according to embodiment of the present utility model, spout 1 is formed on the bulkhead 3 in sand storehouse 30 with connecting, and cover body 2 is fixed on the outer wall in sand storehouse and covers spout 1, thereby forms a nozzle.Emulsion tube need not be installed in this nozzle inside, and structure is simpler, has also solved the drawback that emulsion tube is aging and damage is brought.In addition, outside the sand storehouse that the nozzle of this structure is installed, therefore, nozzle is installed and is changed and need not enter in the sand storehouse, installs simply, changes and safeguards convenient.Simultaneously, this nozzle can not be subjected to the impact and the corrosion of material in the sand storehouse, and prolonged service life greatly, can be to the mobile obstruction that causes of material in the sand storehouse yet, thus be beneficial to the discharging of material in the sand storehouse more.
According to embodiment of the present utility model, the quantity of described spout 1 can be 1-8.The scheme of 3 spouts 1 has been shown among Fig. 2, yet has had no particular limits, any amount of spout can be set as required for the volume cost utility model of spout 1.Described 3 spouts 1 are positioned at the coverage of a cover body 2, and along the circumferential direction arrange, spaced apart each other preset distance, and in other words, a cover body 2 covers 3 spouts 1.Certainly, spout 1 also can be along the circumferential direction to arrange 3-6 in the scope of the covering of cover body 2, and is provided with 1 in the center.Final purpose is to make a nozzle have a plurality of spouts, improves jeting effect.Need to prove that cover body 2 can be provided with a plurality of, each cover body 2 can cover a plurality of spouts 1, thereby forms a plurality of nozzles, and this can understand easily for those of ordinary skill in the art, repeats no more here.
Referring to Fig. 4, according to embodiment of the present utility model, an end of close described cover body 2 inner chambers of described spout 1 is formed with diversion division 11.The initial position that enters spout 1 at fluid is provided with diversion division, can further improve jeting effect.
Referring to Fig. 4, according to embodiment of the present utility model, all be fixed with sleeve pipe 12 in each spout 1, the cross-sectional plane of described sleeve pipe 12 is circular, square or polygon.In order to improve jeting effect, require spout 1 to have certain smoothness, and processing this spout 1 is cumbersome on bulkhead.In order to address the above problem, can process the sleeve pipe 12 of required precision and structure earlier, through hole is set on bulkhead then, described sleeve pipe 12 is fixedly mounted in the through hole, thereby constitutes a spout 1.This spout structure processing is convenient, can improve the precision of spout greatly, improves jeting effect.Described diversion division 11 also is that processing is on described sleeve pipe 12.
Referring to Fig. 4, according to embodiment of the present utility model, the angle a of (along cw or in the counterclockwise direction) is an acute angle between the bulkhead in the axis of the described spout 1 on the circumferencial direction and sand storehouse, and promptly spout 1 tilts with respect to bulkhead, makes the spray angle of fluid in the spout 1 not perpendicular with bulkhead.And the bulkhead that is positioned at the axis of spout 1 at center and sand storehouse is perpendicular.This structure can guarantee that nozzle 20 can be simultaneously to a plurality of direction jet fluids, and this distribution makes and be injected into radially, has improved jeting effect of the present utility model greatly.Need to prove, here so-called acute angle is meant that the axis of spout tilts with respect to bulkhead, for example in Fig. 4, the axis of the spout of lower-left side is an acute angle to bulkhead angle in the counterclockwise direction, and the axis of the spout of upper right side is an acute angle to bulkhead angle along clockwise direction.
Referring to Fig. 1, according to embodiment of the present utility model, described cover body 2 is welded on the outer wall in described sand storehouse.This mounting means is simpler, good sealing effect.Certainly, described cover body 2 also can be installed on the outer wall in described sand storehouse hermetically by helicitic texture.For example, nut of welding is installed in described cover body 2 on the nut again on sand storehouse 1, between nut and the cover body 2 packing seal is set.Adopt the connection mode of screw thread, help the dismounting of cover body 2, make handling labor more simple and convenient.
Referring to Fig. 1, according to embodiment of the present utility model, described connecting portion 21 is formed on the afterbody of described cover body 2, and described connecting portion 21 can be tightly connected with exterior pipeline 5.
Referring to Fig. 3, according to another kind of embodiment of the present utility model, described connecting portion 21 is formed on the sidewall of described cover body 2, and described connecting portion 21 can be tightly connected with exterior pipeline 5.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that under the situation that does not break away from principle of the present utility model and spirit and can change that scope of the present utility model is limited by claims and equivalent thereof to these embodiment.
