Abstract
A horizontal decanter centrifugal with a gas-seal closing structure comprises a drum, a differential mechanism, a base and a feeding tube. The drum is mounted on the base by a first bearing block and a second bearing block, and consists of a tapered section and a straight tube section, a screw is mounted in the straight tube section, one end of the straight tube section is fixed to a large-head end of the tapered section, and the feeding tube is mounted at the other end of the straight tube section. An integral sealing cylinder with an end plate is mounted on the outside of the drum, one end of the end plate is hermetically connected with a cylinder body of the integral sealing cylinder, the other end of the end plate is hermetically connected with a flange cover plate, the integral sealing cylinder is mounted on the base, and a solid-phase outlet flange and a clear liquid outlet flange are respectively arranged on the bottom cylinder wall of the integral sealing cylinder. The horizontal decanter centrifugal has the advantages of fine structural sealing performance and capability of carrying out solid-liquid separation for poisonous or inflammable and explosive gaseous materials.
Description
Technical field
The invention belongs to the occasion that need separate the solid-liquid two-phase mixture of poisonous or flammable explosive gas material in industries such as chemical industry, environmental protection, oil drilling and food, especially a kind of have a sealing gland closed structure horizontal screw centrifuge.
Background technology
With reference to Fig. 1, the horizontal screw centrifuge of prior art is a subdivision casing up and down, and its structure is as shown in Figure 1: rotary drum leans on upper and lower casing sealing; The solidliquid mixture material enters in the rotary drum of doing rotation at a high speed from charge pipe; Under the effect of centrifugal force field, the solid phase that severe is bigger is close to drum inner wall, by rotating in the same way with rotary drum but there is the spiral of certain poor rotating speed to push the small end of rotary drum (cone-element) to; Outside the discharge machine, the less clear liquid of severe is discharged from the overfall that is positioned at the big end of rotary drum automatically.The shortcoming of its existence is: the Drum of Horizontal Screw Centrifuge Based of prior art is leaned on upper and lower casing sealing; Fig. 1 has pointed out the leak point that the horizontal screw centrifuge of prior art leaks easily; Existing structure can not be realized in confined conditions having influenced the application of this type centrifuge to containing poisonous or the flammable explosive gas material carries out Separation of Solid and Liquid.
Summary of the invention
In order to overcome the existing horizontal screw centrifuge problem of closed-loop operation fully, the present invention provides a kind of horizontal screw centrifuge with sealing gland closed structure.
Horizontal screw centrifuge with sealing gland closed structure of the present invention comprises rotary drum, differential mechanism, support, charge pipe, and described rotary drum is installed on the described support through clutch shaft bearing seat, second bearing block; Described rotary drum comprises tapered section and straight length, and described straight length is inner installs spiral, and an end of described straight length is fixed other end installation charge pipe with the stub end of described tapered section; The output of described differential mechanism is connected with described spiral; Input is connected with described rotary drum; It is characterized in that: the outside integral sealing cylinder that has end plate of installing of described rotary drum; One end of described end plate and the cylindrical shell of described integral sealing cylinder are tightly connected, and the other end and described flange plate are tightly connected; Described integral sealing cylinder is installed on the described support; Be respectively equipped with solid phase outlet(discharge) flange and purified liquor outlet flange on the bottom barrel of said integral sealing cylinder.
Described flange plate has Sealed casing pipe.
Described Sealed casing pipe is provided with breather pipe.
The inner ring of described Sealed casing pipe is equipped with sealing ring.
Have vent grooves on the described sealing ring.
4 ~ 6 apertures are set on the described vent grooves.
Described sealing ring adopts engineering plastics to process.
During use; Earlier spiral is packed in the rotary drum, be inserted in the integral sealing cylinder, load onto the flange plate of band Sealed casing pipe then at the two ends of integral sealing cylinder respectively from the little head end of rotary drum; And load onto sealing ring at the flange plate inner ring; After the two ends of rotary drum were loaded onto clutch shaft bearing seat, second bearing respectively, the output with differential mechanism was connected with spiral again, and input is connected with described rotary drum; And clutch shaft bearing seat, second bearing block be contained in respectively on the support, load onto charge pipe at the straight length of rotary drum at last; During use inert gases such as high pressure nitrogen are inserted breather pipe, realize isolation with extraneous air; After rotary drum begins to rotate; The drive differential mechanism is started working; Differential mechanism outputs power to spiral, and it is poor to make that rotary drum and spiral have certain speed, makes solid formation discharge from the purified liquor outlet flange from the discharge of solid phase outlet(discharge) flange, clear liquid after then suspension being separated.
The invention has the beneficial effects as follows: sealing structure property is good, can be used for containing poisonous or the flammable explosive gas material carries out Separation of Solid and Liquid.
