Horizontal type screw settling centrifuge is a kind of efficient centrifugal separation equipment.Current horizontal type screw settling centrifuge just in use, the structure of existing this Horizontal helical type centrifuge is for comprising an outer rotor, be arranged on the internal rotor in outer rotor, in, the rotation direction of outer rotor is identical, on internal rotor, offer cavity connector, thereby the mud in internal rotor is entered in outer rotor by cavity connector, at mud, enter in the process of outer rotor, thereby mud can produce friction with this cavity connector causes cavity connector to produce wearing and tearing, this cavity connector of long duration just returns and is ground with breach, thereby less stable in the time of can causing the quality of internal rotor to alleviate can causing internal rotor rotation due to the generation of breach, therefore the stability of whole horizontal screw centrifuge is all affected, so designing the horizontal screw centrifuge of the replaceable wear-resistant ceramic cover of having of a kind of abrasionproof shoe is necessary.
Summary of the invention
The object of the invention is to overcome the defect of prior art, a kind of horizontal screw centrifuge with replaceable wear-resistant ceramic cover shoe is provided.
For achieving the above object, the present invention adopts a kind of horizontal screw centrifuge with replaceable wear-resistant ceramic cover shoe, it comprises that main control motor, differential mechanism, outer rotor, internal rotor, sewage sludge feed pipe, outer rotor are driven and rotated by main control motor, and differential mechanism is connected with internal rotor one end and is controlled and driven internal rotor to rotate by main control motor; In outer rotor, be provided with centrifugal cavity, internal rotor is located in centrifugal cavity, is provided with mud cushion chamber in internal rotor, and the mouth of pipe of sewage sludge feed pipe is arranged in mud cushion chamber, offers cavity connector on the wall of mud cushion chamber; Wherein, on described cavity connector, be also provided with wearing bush, wearing bush comprises Access Division and abrasionproof portion, Access Division and cavity connector outer wall connect and fix, it is inner that abrasionproof portion stretches into cavity connector, offers charging aperture on wearing bush, and the sidewall of abrasionproof portion charging aperture is provided with one deck friction-proof piece.
Owing to being also provided with wearing bush on cavity connector, on wearing bush, offer charging aperture, it is inner that abrasionproof portion stretches into cavity connector, the sidewall of abrasionproof portion charging aperture is provided with one deck friction-proof piece, by friction-proof piece, replace cavity connector and mud to rub, can reduce the wearing and tearing of cavity connector, improve the internal rotor life-span, easy to maintenance, cost also lowers.
Wherein, the diapire upside of described mud cushion chamber offers arc groove, and the shaft core position place of diapire is provided with boss.Adopt this structure, make mud enter mud cushion chamber
Wherein, described friction-proof piece is potsherd.Friction-proof piece adopts potsherd, considers that the cost of potsherd is lower, and the hardness of pottery is higher, more wear-resistant.
Wherein, described potsherd and charging aperture inwall are tight fit, and charging aperture inwall is provided with groove, and potsherd is located in groove.
Wherein, the cross sectional shape of described cavity connector is rounded.Adopt this structure, make pug velocity flow profile more even
Wherein, the quantity of described cavity connector is at least 2.Adopting a plurality of cavity connectors, is because the pressure that bears of single cavity connector is larger, thus adopt a plurality of cavity connectors, and a plurality of cavity connector also alleviated the scouring force of pug to helical blade root, thus reduced erosion.
Wherein, described Access Division comprises the boss that is arranged in cavity connector outside.
Wherein, this centrifuge also comprises wearing bush fixture, in this wearing bush fixture, offers the groove matching with boss, and wearing bush fixture and internal rotor are bolt to be fixed.Adopt this structure to improve the stability between wearing bush and internal rotor, and be bolted the replacing of being convenient to wearing bush.
