Description
Technical field
the present invention relates to a kind of scraper discharging formula centrifuge, be specifically related to a kind of charge level controller for centrifuge.
Background technology
centrifuge be utilize drum rotating to produce centrifugal inertial force to realize the separation of suspension, emulsion and other heterogeneous material or concentrated machine.
according to separate mode, centrifuge mainly can be divided into filtering type, decanter type two kinds of fundamental types.Perforated wall centrifuge rotor is primarily of high-revolving rotary drum, the filter cloth composition covered in rotatory drum wall; operation principle is: after suspension enters bowl; the rotary drum of High Rotation Speed produces powerful centrifugal force and solid phase particles is deposited on the filter cloth of drum inner wall; liquid phase is discharged by the aperture on filter cloth and rotatory drum wall simultaneously; after solid phase takes off liquid by the high speed of certain hour; after meeting the requirements of water capacity index, shut down discharging and to finish the work process.
the discharge way of perforated wall centrifuge has a variety of, mainly contain the discharging of artificial top, artificial bottom discharge, gravity dumping, the discharging of hanging bag type top and scraper bottom discharge etc. several, the discharging of artificial top refers to that centrifuge filter process completes and after shutting down, drawn off by material by workman with instrument from rotary drum top; The discharging of hanging bag type top is designed to removable by the lip ring of rotary drum, and it connected with filter bag, hangs out discharging after shutdown by suspender; Artificial bottom discharge refers to that centrifuge filter process completes and after shutting down, by workman with instrument material is drawn off from bottom of the drum, gravity dumping refers to that centrifuge filter process completes and after shutting down, material draws off by the conical lower portion of self gravitation effect from rotary drum; Scraper bottom discharge refers to that centrifuge filter process completes and after shutting down, drawn off by material by the mechanical scraper of automatic or manual formula from bottom of the drum.
scraper bottom discharge is the discharge way that 3-foot and flat centrifuge uniquely can realize self-action discharging, realize from middling speed charging, stop reinforced, de-liquid, low speed scraper at a high speed production process, stop the control of this link reinforced most important, once had the control that the various ways such as time controling charging, radar reflection waves Level control, mechanical torque formula Level control carry out the bed of material in rotary drum, the design of this patent is accurately relatively reasonable.
Summary of the invention
technical problem to be solved by this invention solves the deficiencies in the prior art, provides a kind of charge level controller for centrifuge.
in order to reach above object, the technical solution used in the present invention is: for the charge level controller of centrifuge, it comprises the shell stretched in bowl, be arranged at the press button be connected with the centrifuge master controller controlling centrifuge inlet valve switch in shell and by control line, one end to be stretched in shell and the push rod offseted separatably with press button, be connected to the scraping blade of the other end of push rod, be connected with push rod and the returning spring that power makes itself and press button be separated is applied to push rod, when push rod and press button are separated, centrifuge inlet valve is opened, when push rod and press button offset, centrifuge inlet valve cuts out.
further, push rod comprise be positioned at shell and an end and press button offset separatably head part, an end and the connecting rod stretching into shell the other end and be connected with scraping blade, be provided with between an end of connecting rod and the other end of head part and power is applied to connecting rod and head part make connecting rod and head part have the buffer spring of trend away from each other.
further, scraping blade is umbrella shape scraping blade.
further, stretch out shell place at push rod, sealed by dust-proof seal ring between push rod and shell.
further, the base that shell comprises the connecting leg stretched in bowl, is connected with connecting leg, press button is arranged on base inside, and an end of push rod is stretched in base.
the present invention is used for the charge level controller of centrifuge, by adopting technique scheme, when the material in rotary drum increases gradually, when reaching required thickness, material can meet with umbellate form scraping blade, the elastic force that power suffered by umbellate form scraping blade makes push rod overcome returning spring moves backward, when ejector pin contact is sent to the master controller of centrifuge to signal during the knob of push switch.Use the present invention, can make the charging precise control of centrifuge, reaction in time, is protected proper, is realized the automation mechanized operation of unloading under scraper centrifuge, improve the gentle operating efficiency of Automated water of centrifuge.
this material positioner have employed buffer spring simultaneously; after inlet valve cuts out, still have a small amount of material enter rotary drum; umbellate form scraping blade is made to continue to move a small amount of distance inwards; at this moment buffer spring plays cushioning effect; avoid Material control device to be subject to impact shock, available protecting is carried out to push switch simultaneously.
this material positioner is provided with push switch, opens effectively simple.
this material positioner adopts umbellate form scraping blade, and umbellate form scraping blade effectively can improve the contacting efficiency with material, and make the Impact direction of push rod accurate, stressed size is even.
