Abstract
The invention relates to a horizontal spiral discharge settling centrifuge which comprises a revolving drum and a screw; spiral blades are arranged on the screw; a housing covers the revolving drum; a feed opening communicated with the inner cavity of the screw is formed in one end of the housing; a liquid outlet is formed in one end, close to one end of the feed opening, of the lower end of the housing; a bleed hole is formed in the other end; at least 20 grooves are formed in the inner wall of the revolving drum in the circumferential direction. The grooves are formed in the inner wall of the revolving drum to prevent a liquid phase from forming a water film and a solid phase from accumulation, the abrasion of the blade is avoided, and the normal work of the blade is not influenced even if part of the solid phase is accumulated in the grooves.
Description
Technical field
The present invention relates to a kind of horizontal spiral discharge sedimentation centrifuge.
Background technology
Horizontal spiral discharge sedimentation centrifuge is called for short horizontal screw machine, can be used for the production process of work, agriculture, byproduct, is again the key equipment of sludge dewatering system in environmental improvement engineering.The separated solid-liquid particle of energy equivalent diameter>=3 μ m, weight concentration ratio≤10% or volumetric concentration ratio≤70%, liquid-solid density contrast>=0.05g/cm
3various suspension.
Horizontal spiral discharge sedimentation centrifuge mainly comprises high-revolving rotary drum and turns to screw rod identical and that rotating ratio rotary drum is slightly high or lower slightly with rotating speed, on screw rod, there is the blade that spiral arranges, when wanting separated suspension to enter after bowl, the rotary drum of High Rotation Speed produces powerful centrifugal force the solid phase particles larger than density of liquid phase is deposited to drum inner wall, because the rotating speed of screw rod and rotary drum is different, the two has relative motion (being speed discrepancy), utilize the relative motion of screw rod and rotary drum that the solid phase that is deposited on drum inner wall is pushed to the discharge of rotary drum small end exit, clear liquid after separation is discharged from the centrifuge other end.When carrying out liquid-solid separation, liquid phase can form moisture film at rotary drum inner surface, once form moisture film, can rotate together with rotary drum, just lose centrifugation.In prior art, for fear of liquid phase, form moisture film, need to set up 3-4 axial divider at rotary drum inner surface, the height of divider is 5mm left and right, can reduce the formation probability of moisture film, improves separating effect.But after setting up divider, the sandstone that viscosity is larger can be piled up and form solid slag muck near divider, time has been grown and has reached after certain thickness, blade can wear and tear, after blade wear, further can cause again solid slag muck thickness to increase, general operation just need to once be cleaned after 3 months, had increased operating cost and the maintenance cost of equipment.
Summary of the invention
Technical problem to be solved by this invention is: overcoming horizontal screw machine in prior art can form solid slag muck at drum inner wall, and the technical problem of wearing and tearing blade, provides a kind of horizontal spiral discharge sedimentation centrifuge, can prevent from forming solid slag muck, avoids the wearing and tearing of blade.
The technical solution adopted for the present invention to solve the technical problems is: a kind of horizontal spiral discharge sedimentation centrifuge, comprise rotary drum and screw rod, on described screw rod, there is the blade that spiral arranges, rotary drum is covered with housing outward, one end of housing is provided with the charging aperture that is communicated with screw rod inner chamber, described housing lower end near one end of charging aperture be provided with leakage fluid dram, the other end is provided with slag-drip opening, the inwall of described rotary drum is along circumferentially offering at least 20 grooves.By offer a plurality of grooves at drum inner wall, can prevent that liquid phase from forming moisture film, can prevent again solid phase accumulation, also just avoid the wearing and tearing of blade, solid phase has part and is deposited in groove, but can not affect the normal operation of blade.
A kind of embodiment of groove, the radial section of described groove is shaped as rectangle.
A kind of embodiment of groove, the radial section of described groove is shaped as circular arc.
Concrete, the internal diameter of described rotary drum is 530mm, the quantity of the groove on drum inner wall is 24-36.
As preferably, described 24-36 groove is along being circumferentially evenly arranged on the inwall of rotary drum.
The invention has the beneficial effects as follows, horizontal spiral discharge sedimentation centrifuge of the present invention, on existing horizontal screw machine, improved the structure of rotary drum, by set up a plurality of grooves at drum inner wall, can prevent that liquid phase from forming moisture film, can prevent again solid phase accumulation, also just avoid the wearing and tearing of blade, solid phase has part and is deposited in groove, but can not affect the normal operation of blade, reduce maintenance cost and the operating cost of horizontal screw machine.
