Description
Technical field
The present invention relates to the preparation equipment technical field, particularly a kind of anti-precipitation equipment that is used for thickener overflow chute.
Background technology
At present, be equipped with thickener in the ore-sorting system in a lot of ore dressing plants.Because the effluent concentration of thickener is high, overflow gets into after the overflow chute, and sedimentation takes place under the effect of gravity solid particle wherein, is deposited on the bottom of overflow chute.As time goes on, precipitum deposits more and morely, influences the drainage of overflow, and the cleaning of will stopping when serious has increased labor intensity of operating personnel, has influenced working continuously of ore-sorting system, has reduced productivity ratio.
Summary of the invention
The object of the invention provides a kind of simple in structure, anti-precipitation equipment that is used for thickener overflow chute of preventing precipitum deposition.
The objective of the invention is to realize through following technical proposals:
The anti-precipitation equipment that is used for thickener overflow chute of the present invention; Comprise the annular overflow chute that has internal ring wall and external annulus, be located at the gear ring at this external annulus top, therewith the gear that is meshed of gear ring, be located at the circuit orbit in the gear ring outside, the roll roller that is connected, the rotation platform that is connected with gear of roller and the dolly that is located at this rotation platform upper surface therewith of circuit orbit therewith; It is characterized in that being provided with anti-precipitation equipment at the lower surface of said rotation platform; This anti-precipitation equipment by with the lower surface of said rotation platform connecting rod connected vertically; The connecting rod screen that connects that fixes is formed therewith, and this screen vertically inserts in the annular overflow chute.
Described connecting rod is threaded with the lower surface of described rotation platform.
The top margin of said screen is higher than the liquid level of overflow in the annular overflow chute.
Distance between the bottom surface of the base of said screen and annular overflow chute is 30～50mm.
The dual-side of said screen respectively and the internal ring wall of annular overflow chute and the distance between the external annulus be 20
～30mm。
The material of said screen is a stainless steel.
The advantage that is used for the anti-precipitation equipment of thickener overflow chute of the present invention is:
Lower surface at rotation platform vertically is provided with connecting rod, is connected through bolt between this connecting rod and the dolly, is convenient to change, and connecting rod fixes with screen and is connected, and this screen vertically inserts in the annular overflow chute, and the screen material is a stainless steel.Screen, can blow foam in the overflow and suspension off because the top margin of screen is higher than the liquid level of overflow in the annular overflow chute along with the rotation of rotation platform moves in annular overflow chute, and its outlet side along the overflow chute is discharged.Simultaneously,, stirring overflow in annular overflow chute, the precipitum in the overflow can't deposited, along with overflow is discharged from outlet side because screen ceaselessly moves.Prevent the deposition of precipitum effectively, reduced labor intensity of operating personnel, guaranteed the continuous running of ore-sorting system, improved operating rate, reduced production cost.
The present invention is simple in structure, and installation and maintenance are convenient, and economical and practical, effect is obvious.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present invention.
Like Fig. 1 shown in you; The present invention is used for the anti-precipitation equipment of thickener overflow chute; Comprise the annular overflow chute that has internal ring wall 10 and external annulus 8, be located at the gear ring 6 at these external annulus 8 tops, therewith the gear 4 that is meshed of gear ring 6, be located at the circuit orbit 5 in gear ring 6 outsides, the roll roller 3 that is connected, the rotation platform 2 that is connected with gear 4 of roller 3, the dolly 1 that is located at these rotation platform 2 upper surfaces therewith of circuit orbit 5 therewith; It is characterized in that being provided with anti-precipitation equipment at the lower surface of said rotation platform 2; This anti-precipitation equipment by with the lower surface of said rotation platform 2 connecting rod 7 connected vertically; Connecting rod 79 compositions of screen of fixing and connecting therewith, connecting rod 7 can adopt with dolly and be threaded, and is convenient to replacing like this.Described screen 9 vertical insertions in the annular overflow chute, screen is a stainless steel.The top margin of screen 9 is higher than the liquid level of overflow in the annular overflow chute; Distance between the bottom surface of the base of screen 9 and annular overflow chute is 30～50mm, the dual-side of screen 9 respectively and the internal ring wall 10 of annular overflow chute and the distance between the external annulus 8 be 20～30mm.This screen 9, can blow foam in the overflow and suspension off because the top margin of screen 9 is higher than the liquid level of overflow in the annular overflow chute along with the rotation of rotation platform 2 moves in annular overflow chute; Its outlet side along the overflow chute is discharged; The space of screen is different according to the water velocity difference, 3～10 millimeters of scopes, and speed is big more; The space is big relatively more, and anti-precipitation equipment running speed is 6～10 meters/minute approximately.Drive screen 9 in the dolly operation process and ceaselessly in annular overflow chute, move, stirring overflow, the precipitum in the overflow can't be deposited, along with overflow is discharged from outlet side.
The operation principle that is used for the anti-precipitation equipment of thickener overflow chute of the present invention is:
Dolly driven in rotation distal ends, rotation platform drives connecting rod and screen moves together.Because screen vertically inserts in the annular downflow weir, and the top margin of screen is higher than the liquid level of overflow in the annular downflow weir, so screen blows foam in the overflow and suspension off when operation, its outlet side along downflow weir discharged.Simultaneously,, stirring overflow in annular downflow weir, the precipitum in the overflow can't deposited, along with overflow is discharged from outlet side because screen ceaselessly moves.
The present invention has prevented the deposition of precipitum effectively, has reduced labor intensity of operating personnel, has guaranteed the continuous running of ore-sorting system, has improved operating rate, has reduced production cost.And simple in structure, installation and maintenance are convenient, and economical and practical, effect is obvious.
