Abstract
The invention discloses a horizontal type scraper discharging centrifugal machine which comprises a machine frame. The machine frame is provided with a rotating shaft assembly, a revolving drum assembly, a shell assembly and a power mechanism. The rotating shaft assembly comprises a mounting base arranged on the machine frame, and a rotating shaft penetrates into the mounting base in a rotating mode through two sets of bearings arranged on the rotating shaft in a sleeving mode. The revolving drum assembly and the power mechanism are connected with the two ends of the rotating shaft respectively. The shell assembly comprises a rear rib plate which is arranged on the machine frame, a barrel-shaped outer shell which is arranged on the rear rib plate and covers the revolving drum assembly, and a front end cover which is hinged to the barrel-shaped outer shell. The rotating shaft assembly penetrates through the rear rib plate. A feeding pipe, a scraper assembly and a discharging pipe penetrate into the front end cover. The barrel-shaped outer shell is provided with an air exhaust outlet. The rear rib plate is provided with at least one induced air opening. The centrifugal machine can prevent lubricating oil in the bearings of the rotating shaft from escaping.
Description
Technical field
The present invention relates to a kind of horizontal scraper discharging centrifuge.
Background technology
Horizontal scraper discharging centrifuge is the perforated wall centrifuge of continuous running, intermittently operated, and its control mode is automatically control, also can Non-follow control.The processes such as the charging in centrifuge operations process, separation, washing, dehydration, discharging and filter cloth regeneration generally all complete under full-speed state, and the single cycle time is short, and treating capacity is large, and can obtain more dry filter residue and good clean result.The scope of application of horizontal scraper discharging centrifuge, it can be used for the separation being about greater than the solid-liquid two-phase suspension of 10 μm containing solid phase particles particle diameter.Horizontal type scraper centrifuger is widely used in the separation of the over one hundred kind of material such as sulphur ammonium, sulphur sodium, nickelous sulfate, ferrous sulfate, starch, boric acid, anthracene, polyvinyl chloride, urea, heavy alkali, caustic soda, salt, potassium chloride, potassium sulfate in the industrial departments such as chemical industry, light industry, pharmacy.
Bowl drives the motion of centrifuge inner air when rotation, make enclosure create negative pressure, and the lubricating oil of bearing block inside can be drawn onto rotary drum inside and make material contaminated under the effect of negative pressure.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of horizontal scraper discharging centrifuge avoiding the lubricating oil in rotating shaft upper bearing (metal) to escape.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of horizontal scraper discharging centrifuge, comprise frame, frame is provided with rotating assembly, drum assembly, housing unit and actuating unit, rotating assembly comprises the mount pad be arranged in frame, and rotating shaft is rotated by two groups of bearings sheathed on it and is located in mount pad; Described drum assembly and actuating unit are connected with rotating shaft two ends respectively, housing unit comprises the rear gusset be arranged in frame, be arranged on rear gusset and the cylindrical case be located on drum assembly and be arranged on the drive end bearing bracket be hinged on cylindrical case, rotating assembly passes from rear gusset, drive end bearing bracket is equipped with feed pipe, doctor assemblies and discharge duct, described cylindrical case is provided with exhaust outlet, and described rear gusset is provided with at least one air-vent.
As the preferred scheme of one, described rear gusset inner surface is provided with liquid barrier above air-vent, rear gusset inner surface is provided with lower liquid barrier below air-vent.
As the preferred scheme of one, described air-vent is positioned at the position near rotating assembly on rear gusset.
The invention has the beneficial effects as follows: owing to air-vent being opened on rear gusset, make rotary drum when suction extraneous air, position of bearings place pressure and atmospheric pressure close, under avoiding the acting in conjunction of negative pressure in housing unit and bearing block internal pressure, the lubricating oil in bearing block is made to be drawn onto the inner and situation of contaminated material of rotary drum.
Owing to there is no the structure of other complexity above rear gusset, its surface is had and larger utilizes space, can air-vent be equipped with up and down liquid barrier with avoid centrifugal after the liquid situation that can spill by air-vent.
Because air-vent to be positioned on rear gusset near the position of rotating assembly, better ensure that position of bearings there will not be negative pressure state, the lubricating oil avoided in bearing block is drawn onto the inner and situation of contaminated material of rotary drum.
