Abstract
The invention relates to a grading device for non-homogeneous separation of solid particles, in particular to a centrifugal spiral casing feeding hydrocyclone which adopts the preliminary sedimentation function of a feeding tube for improving the separation efficiency. The device comprises a hydrocyclone body, an overflow tube arranged at the top of the hydrocyclone body, a feeding tube arranged at the upper part of the hydrocyclone body, and an underflow pipe arranged at the lower end of the hydrocyclone body, and is characterized in that the feeding tube is in mutually intersecting connection with the hydrocyclone body after being wound around the hydrocyclone body in a section or a plurality of circles. In the invention under the action of centrifugal force, the solid particles conduct the preliminary sedimentation in the feeding tube wound around the hydrocyclone body, that is, the solid particles are thrown to the outer side under the action of centrifugal sedimentation before entering the hydrocyclone body, so that the solid particles can be more effectively separated into the under flow, the separation efficiency is improved, and the invention has the advantages of simple structure, high separation efficiency and the like.
Description
Technical field:
The present invention relates to belong to heterogeneous separation, solid phase particles grading plant, specifically a kind of anticentripetal spiral casing feeding swirler that relies on the interior pre-sedimentation effect of feed pipe to improve separative efficiency.
Background technology:
At present, in order to carrying out the hydrocyclone of heterogeneous separation, solid phase particles classification, form by body, the overflow pipe that is installed in bodies top, the feed pipe that is positioned at body top, the underflow pipe that is installed in the body lower end.Feed pipe passes through connected mode mutually with body and is generally tangentially, and promptly feed pipe mainly contains forms such as tangential feed pipe, involute-type feed pipe, spiral line type feed pipe, arc line type feed pipe.So far, the design of the feed pipe of nearly all form is not all considered pre-sedimentation was carried out in charging before entering cyclone body from feed pipe, that is, particle belongs to even distribution basically on the feed pipe section.
Yet, nearest result of study shows, for onesize solid particle, before solid particle in the feed pipe is entering cyclone body the closer to the cyclone body outer wall, particle separated probability that enters underflow in hydrocyclone is big more, just separative efficiency is big more (sees: Zhi-Bin Wang, Liang-Yin Chu, Wen-MeiChen, Sheng-Gui Wang, " Experimental investigation of the motion trajectory of solidparticles inside the hydrocyclone by a Lagrange method ", Chemical Engineering Journal (2007), doi:10.1016/j.cej.2007.05.037.).This result of study explanation before entering cyclone body, can rely on pre-sedimentation effect to be thrown near cyclone body outer wall one side as fruit granule, and then the separative efficiency after particle enters cyclone will be improved.So far, do not see the report that SEPARATION EFFICIENCY IN HYDROCYCLONE is strengthened in pre-sedimentation effect in the dependence feed pipe that similar the present invention proposes at home and abroad as yet.
Summary of the invention:
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of anticentripetal spiral casing feeding swirler that relies on the interior pre-sedimentation effect of feed pipe to improve separative efficiency is provided.
The present invention can reach by following measure:
A kind of anticentripetal spiral casing feeding swirler, form by cyclone body, the overflow pipe that is installed in the cyclone body top, the feed pipe that is positioned at cyclone body top, the underflow pipe that is installed in the cyclone body lower end, it is characterized in that feed pipe passes through connection mutually around one section of cyclone body or a few Zhou Houyu cyclone body.
Be looped around the outer feed pipe section of cyclone body among the present invention and both can be rectangle, also can be for square, circular, ellipse etc.
Feed pipe is at least one among the present invention, its with cyclone body mutually the mode of passing through can be tangent type or involute-type, also can adopt spiral line type or arc line type, make wearing and tearing minimum, charging is more unimpeded.
Feed pipe of the present invention can be a half cycle around all numbers of cyclone body, also can be a week or how all, to improve separative efficiency.
The present invention adopts above-mentioned feed pipe design; owing to be subjected to centrifugal action; solid phase particles can carry out pre-sedimentation in the feed pipe outside being looped around cyclone body; that is to say; solid phase particles was got rid of in an outer side by the centrifugal sedimentation effect before entering cyclone body; just can more effectively be divided to advance underflow after entering cyclone body like this,, be had simple in structure, separative efficiency advantages of higher so separative efficiency is mentioned.
Description of drawings:
Accompanying drawing is a structural representation of the present invention, also is the structural representation of a kind of embodiment.
Fig. 1 is a structural representation.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is further described:
A kind of anticentripetal spiral casing feeding swirler, as Fig. 1, shown in Figure 2, by cyclone body 3, be installed in the overflow pipe 4 at cyclone body top, be positioned at the feed pipe 1 on cyclone body top, the underflow pipe 2 that is installed in the cyclone body lower end is formed, cyclone body 3, overflow pipe 4, the structure and the interconnected relationship of underflow pipe 2 are same as the prior art, this does not give unnecessary details, to be feed pipe 1 pass through connection around behind 3 one sections of the cyclone bodies with cyclone body 3 to feature of the present invention mutually, be looped around cyclone body 3 outer feed pipe 1 sections among the present invention and both can be rectangle, also can be for square, circular, ellipse etc.; Feed pipe 1 is at least one among the present invention, its with cyclone body 3 mutually the mode of passing through can be tangent type or involute-type, also can adopt spiral line type or arc line type; Feed pipe 1 of the present invention is meant also can be greater than a week less than a week around 3 one sections of cyclone bodies, can also be several weeks.
Embodiment 1: the shape of present embodiment and structure are as shown in Figure 1 and Figure 2.Cyclone body 3 is the tapered thin-wall barrel of post; Overflow pipe 4 is pipe or Taper Pipe, is installed in cyclone body 3 tops, and the one end is positioned at cyclone body 3, and the other end is positioned at outside the cyclone body 3; Underflow pipe 2 is pipe or Taper Pipe, is installed in cyclone body 3 lower ends; Feed pipe 1 is one, and section is a rectangle, is positioned at cyclone body 3 tops and rounds outside cyclone body 3 and pass through mutually with cyclone body 3, and the mode of passing through is an involute-type mutually.
Embodiment 2: be with the difference of embodiment 1: 1, cyclone body 3 is bicone (two sections have different cone angle degree cone) thin-wall barrel for the awl section; 2, feed pipe 1 is two, is positioned at cyclone body 3 tops and rounds outside cyclone body 3 and pass through mutually with cyclone body 3, and section is oval, and the mode of passing through is an involute-type mutually.
Embodiment 3: be with the difference of embodiment 1: 1, cyclone body 3 is the hyperbolic-type thin-wall barrel for the awl section; 2, around 2 weeks, section is circular to feed pipe 1 outside cyclone body 3, and the mode of passing through is a spiral line type mutually.
