Abstract
A kind of cis and inverse complex centrifugation machine for Separation of Solid and Liquid, owing to there is secondary auger conveyor that clear liquid is carried out secondary separation, clear liquid has carried out the 3rd separation again in pump chamber, increased the sedimentation section, make centrifuge under the situation that does not add any medicament, use secondary sludge to be separated into possibility at industry, sanitary sewage, reach higher separating effect with less separating factor, greatly improve than existing downflow type centrifugal separator in life-span and versatility.
Description
The present invention relates to a kind of equipment for separating liquid from solid, promptly cis and inverse complex and spiral centrifuge can separate the secondary sludge of industry, sanitary sewage.
At existing downflow type centrifugal separator, it has only an auger conveyor forward, cylinder and circular cone intersection at auger conveyor, if the fluid mouth of pipe directly to an awl tube face, the part sediment is floating again discharges with clear liquid because the pressure reduction that conical surface resistance produces forces, reduced separating effect, the containing filth amount of clear liquid is 2～1.5 ‰.Because centrifuge reaches 3000 rev/mins high speed rotating, shake greatlyyer, influence environment and health, its noise influences the timely discovery of mechanical disorder again.
The objective of the invention is in order to overcome above-mentioned shortcoming, make clear liquid carry out secondary separation, reach higher separating effect with less separating factor, the cis and inverse complex centrifugal separator can be used in the secondary sludge of industry, sanitary sewage under the situation that does not add any medicament separation ， And is reduced to below 1 ‰ the clear liquid containing filth amount.The life-span and the versatility of this machine greatly improve than downflow type centrifugal separator.
Support fixing means of the present invention is to adopt the supporting of full floating spring rubber, his positive effect and advantage are that equipment can move arbitrarily, on the level land, can move, need not to excavate separately and watering appliance basis and foot bolt regularly, and eliminate the adverse effect that vibrations cause human body and environment, working environment is improved, thereby be easy to the fault of timely discovering device.
The cis and inverse complex centrifugal separator is through the motor transmission by a pair of pulley concial disk, transmission rotary drum behind the shell of its medium and small pulley concial disk transmission cycloid differential mechanism, pay auger conveyor by the serration transmission on the other end axle of rotary drum again, so the synchronization of rotary drum and pair auger conveyor.Big pulley concial disk drives main auger conveyor by splined shaft after cycloid differential mechanism speed change, the rotating speed of main auger conveyor is higher than pays auger conveyor, and the maximum difference of the two rotating speed is 40～20 rev/mins.
Material is entered by the feed pipe in the hollow shaft, in the feeding chamber of main pair auger conveyor end cap, be evenly equipped with feedhole on the cylindrical wall of end cap and on the Hollow Transmission Shafts of pair auger conveyor, on the cylindrical wall between the feedhole, be symmetrically distributed with 4～6 fluid short tubes parallel with axle.
Main auger conveyor is made up of cylindrical section helical blade, conical section helical blade and the conveyor screw that is connected the two.Be symmetrically distributed with several fluid holes for the first time on the spirochetal perpendicular end surface of junction mutually in cylindrical section and conical section, pay cinder hole in the first time that cylindrical section and conical section are provided with radial symmetric mutually on the spirochetal cylinder end face of junction, the position of paying cinder hole for the first time is at the upstream end of paying auger conveyor, pay auger conveyor in main spirochetal cylindrical section, both same axial lines, and their hand of spiral is opposite.
The main fluid short tube of paying on the auger conveyor end cap is to pay the clear liquid introducing pump chamber that auger conveyor separated, pump chamber is to be formed by rotary drum bonnet, taper labyrinth ring, clear liquid in this pump chamber through separating for the third time, be evenly equipped with on the taper labyrinth ring and pay cinder hole for the second time, symmetric arrangement has fluid hole for the third time on the rotary drum bonnet.The center that fluid hole is arranged in the rotary drum bonnet is on the mutual unequal circumference of its diameter of the center of circle, only open the fluid hole on same circumference during operation, seal fluid hole on other circumference with plug screw, regulate the flow of discharge opeing and the clarity of discharge opeing, be inversely proportional between clarity and the flow with this.
The supporting of full floating spring rubber is in order to replace the foundation bolt on support and the basis.The upper bracket of this supporting is welded on the frame of machinery equipment, is into spring between undersetting and the upper bracket, puts into the elastic bearing pad in the lower end of undersetting.
