Abstract

The utility model discloses a cyclone separator, which comprises an elbow, an overflow connecting pipe, a feeding pipe, a volute body, an overflow pipe, a cylinder, a cone, a first mud valve, a second mud valve and a skirt belt. The elbow is fixed to one end of the overflow connecting pipe, the other end of the overflow connecting pipe is fixed to the volute body, the feeding pipe is fixed to one side of the volute body, the overflow pipe is disposed between the volute body and the cylinder, the cone is fixed to the lower end of the cylinder, and the first mud valve, the second mud valve and the skirt belt are sequentially disposed at the lower end of the cone. A water cyclone is additionally mounted at an outlet of a mud pump of a drag suction dredger so as to increase settling speed of dredging mud, concentration loading and overflowing of the dredging mud are completed at one step, and loading efficiency of the drag suction dredger is improved.

Description

Cyclone separator

Technical field

The utility model relates to a kind of separator, particularly a kind of cyclone separator.

Background technology

When chiltern or the construction of clay silt navigation channel, the trailing suction hopper dredger stowage time is divided into stowage period and overflow period, and the overflow time has occupied about 70% of the whole stowage time in the construction.Through overflow, improve the concentration in the spoil hopper in the transportation to a certain extent, also only account for about 36% of hopper capacity, but prolonged the time of dredging greatly, and average spill losses is about 45%.Spill losses is the massive losses of human and material resources, financial resources.Stowage concentration is low to be wasted in great amount of time in the process of transportation, also is to influence the efficiency of construction key factor.

The utility model content

The utility model technical problem to be solved provides a kind of cyclone separator; It installs the sinking speed that hydrocyclone is strengthened dredging soil additional in the outlet of trailing suction hopper dredger dredge pump; Once accomplish the concentrated stowage and the overflow of dredging soil, improve trailing suction hopper dredger stowage efficient.

For solveing the technical problem; The utility model provides a kind of cyclone separator, it is characterized in that, it comprises, and elbow, overflow adapter, feed pipe, volute casing, overflow pipe, circle are simplified, bullet, first spoil disposal cut down body, second spoil disposal cuts down body and opotism; The end that elbow and overflow are taken over is fixed; The other end and volute casing that overflow is taken over are fixed, and feed pipe is fixed on a side of volute casing, overflow pipe be located at volute casing and justify simplified between; Bullet is fixed on the simplified lower end of circle, and first spoil disposal cuts down body, second spoil disposal and cuts down the lower end that body and opotism are located at bullet successively.

The positive progressive effect of the utility model is: the utility model installs the sinking speed that hydrocyclone is strengthened dredging soil additional in the outlet of trailing suction hopper dredger dredge pump, once accomplishes the concentrated stowage and the overflow of dredging soil, improves trailing suction hopper dredger stowage efficient.

Description of drawings

Fig. 1 is the structural representation of the utility model cyclone separator.

The specific embodiment

Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.

As shown in Figure 1; The utility model cyclone separator comprises that elbow 1, overflow take over 2, feed pipe 3, volute casing 4, overflow pipe 5, circle are simplified 6, bullet 7, first spoil disposal cut down body 8, second spoil disposal cuts down body 9 and opotism 10; Elbow 1 is fixed with an end of overflow adapter 2; The other end of overflow adapter 2 and volute casing 4 are fixing, and feed pipe 3 is fixed on a side of volute casing 4, and overflow pipe 5 is located between volute casing 4 and the circle simplified 6; Bullet 7 is fixed on circle simplified 6 lower end, and first spoil disposal cuts down body 8, second spoil disposal and cuts down the lower end that body 9 and opotism 10 are located at bullet 7 successively.

The two phase mixed liquors that the utility model cyclone separator will separate inject with the tangential admission mouth of certain pressure from cylinder top; Thereby in cyclone separator, form strong rotatablely moving; Because gently with the varying in size of suffered centrifugal force of heavy phase and fluid drag force; Major part is gently discharged from overflow pipe through the interior eddy flow that moves upward, and most of heavy phase and the remaining wall that gently hands down are discharged from underflow opening with the outer eddy flow that moves downward.The separation principle of the utility model cyclone separator is centrifugation.In the eddy flow centrifugal field of cyclone separator, the suffered inertial centrifugal force rate of solid particle suffered gravity in gravitational field is much bigger, has strengthened separation process greatly, has shortened the sedimentation time of solid formation.Like this, the utility model installs the sinking speed that hydrocyclone is strengthened dredging soil additional in the outlet of trailing suction hopper dredger dredge pump, once accomplishes the concentrated stowage and the overflow of dredging soil, improves trailing suction hopper dredger stowage efficient.

Though more than described the specific embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these embodiments.Therefore, the protection domain of the utility model is limited appended claims.
