Abstract
The utility model provides a high-efficiency coarse powder separator which is mainly applied to separation of coarse powders. The high-efficiency coarse powder separator comprises a discharge pipe, a tangential baffle plate, a coarse powder retention chamber, an external passage, an inflated cone and a feed pipe, wherein the discharge pipe is arranged at the upper part of the coarse powder retention chamber, the inflated cone is arranged at the lower part of the coarse powder retention chamber, the feed pipe and a powder return pipe are arranged at the lower part of the inflated cone, and the tangential baffle plate is arranged above an outer conical pipe. The utility model is characterized in that an adjusting rod is arranged on the tangential baffle plate and can adjust the opening degree of the tangential baffle plate, a non-return plate is welded at the top of the inflated cone, the coarse powder retention chamber is formed in the inner cavity of an inner cone with a bell body, the inner cone and the outer conical pipe are both arranged on the non-return plate, the external passage is the space formed between the inner cone and the outer conical pipe, and the upper part of a movable door is connected with the outer wall of the inner cone through a movable shaft, the lower part of the movable door is free. The utility model solves the problems as follows: in the traditional coarse powder separator, the adjusting rod of the tangential baffle plate can not be adjusted, leading to the failure of controlling the particle size of powdered coal; and no movable door is arranged below the coarse powder retention chamber, so that the separation effect is affected, and powdered coal can return to increase the re-milling load of a mill, affect the yield of the mill and increase the power consumption and cost.
Description
Technical field
The utility model is mainly used in the separation of coal dust, is specifically related to a kind of efficient mill separator.
Background technology
Existing mill separator, comprise discharge nozzle, tangential baffle plate, meal retained chamber, outer tunnel, diverging cone, feed pipe etc., the deficiency of its existence is: existing tangential baffle plate adjusting rod connects as one and can't regulate, and does not have dial, and coal powder thickness can't be regulated; Meal retained chamber is no valve down, but be provided with slit about 30mm, defective coal dust enters diverging cone by the slit and returns grinding machine through powder retrieving pipe, and the wind of diverging cone also can enter meal retained chamber simultaneously, influences separating effect, it is big to cause coal dust to return the grinding machine amount, the amount of refacing strengthens, and influences mill output, and production efficiency is low, and the also corresponding increase of power consumption, production cost improves.
Summary of the invention
In order to solve the problem of existing mill separator by inferior separating effect, the utility model provides a kind of efficient mill separator.
The utility model is to adopt following technical scheme to realize: efficient mill separator, comprise discharge nozzle, tangential baffle plate, meal retained chamber, outer tunnel, diverging cone, feed pipe, the top of meal retained chamber is provided with discharge nozzle, the bottom of meal retained chamber is provided with diverging cone, the bottom of diverging cone is provided with feed pipe and powder retrieving pipe, tangential baffle plate is arranged on the top of outer Taper Pipe, it is characterized in that tangential baffle plate is provided with the adjusting rod that can regulate tangential baffle opening size; The diverging cone welded top has check plate, the inner chamber of the inner cone of band clock body is a meal retained chamber, inner cone, outer Taper Pipe are installed on the check plate, the space that forms between inner cone and the outer Taper Pipe is outer tunnel, dodge gate top is connected with the inner cone outer wall by movable axis, and free end is formed at the bottom is so-called dodge gate.
The equipment that is used with the utility model also has air exhauster.
By inlet tube suction diverging cone, the meal particle is played kinetic energy disappearance on check plate to coal dust under the effect of blower fan wind-force, and returning grinding machine by gravity along powder retrieving pipe is first separation.Fine grained produces whirlwind along outer tunnel through tangential baffle plate, qualified coal dust enters pulverized-coal collector with air-flow under the whirlwind effect, coarse granule falls into meal retained chamber bottom at centrifugal action lower edge inner cone inwall, coal dust is detained to reach when a certain amount of opens dodge gate, and returning grinding machine along diverging cone through powder retrieving pipe is secondary separation.
The utility model has solved traditional mill separator because tangential baffle plate adjusting rod can't be regulated, and causes coal powder thickness to regulate; And no valve influences separating effect under the meal retained chamber, causes coal dust to return the grinding machine amount of refacing and strengthens, and influences mill output, and the also corresponding increase of power consumption, the problem that cost improves.
The utility model can accurately control to adjust fineness of pulverized coal flexibly, to satisfy production requirement.
