Abstract
The invention relates to an antilocking mechanism by discharged ash of a star feeder, comprising a feed inlet, a casing and a feed outlet, wherein the upper end of the casing is a funneled feed inlet; the lower end of the casing is a funneled feed outlet; an inner chamber is arranged inside the casing; the inner chamber is provided with star wheel rotors with equant structures; the star wheel rotors are connected with a transmission shaft. The invention is characterized in that a plurality of V-shaped bosses are arranged on the inner wall of one side of the feed inlet which has the same rotating direction with the star wheel rotors; the distance between the V-shaped bosses is L1; the width of the V-shaped boss is L2 and the length is t; the diameter of the lower end of the feed inlet is T and T is greater than t; and a layer of outer cover casing is arranged outside the casing. The invention has simple structure, economic processing, and is beneficial for the smooth falling off of the powder from the outlet.
Description
Technical field
The present invention relates to the even output mechanism of a kind of powder-material, especially a kind of antilocking mechanism of star feeder.
Background technology
Star-like feeder is the common even output mechanism of powder-material, because powder-material has easy formation piece under the situation of pressurized and humidity, so star-like feeder need consider to expect to form the stuck phenomenon of piece putty when designing.The star-like feeder of general structure, when star-wheel clockwise rotated, the powder-material that falls from the top was easily piled up at inlet point, in the course of time, especially expects the putty phenomenon very easily to occur under the situation of high humidity.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of simple in structure, processing economy is provided, help powder from exporting the anti-stuck mechanism of ash discharge of the star-like feeder that falls smoothly.
According to technical scheme provided by the invention, described antilocking mechanism of star feeder, comprise inlet point, shell and discharging opening, the upper end of described shell is funnelform inlet point, the lower end of shell is funnelform discharging opening, is inner chamber in the shell, is provided with star wheel rotor in inner chamber, this star wheel rotor is connected with transmission shaft on being installed on shell; It is characterized in that: on a described inlet point side inwall identical, several boss are set with the star wheel rotor rotation direction.
Described boss is the V-arrangement boss.Distance between described boss is L1, and the wide of boss is L2, and long is t; The lower end diameter of described inlet point is T, and T＞t.Be outside equipped with one deck outer casing at described shell.
In described star wheel rotor, several baffle plates evenly are set on runner, described baffle plate all passes the center of circle of runner.Described boss is put together by two triangle cushion blocks; The bottom surface of two triangle cushion blocks is all identical with the inwall of inlet point, and the top margin of two triangle cushion blocks is fitted mutually; The section of two triangle cushion blocks is all triangular in shape.
The present invention is simple in structure, processing is economical, helps powder to fall from exporting smoothly.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a birds-eye view of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete accompanying drawing and example.
As shown in the figure: anti-jamming mechanism comprises star wheel rotor, outer casing 2, V-arrangement boss 3, transmission shaft 4, inlet point 5, inner chamber 6, discharging opening 7, shell 8 etc.
The upper end of shell 8 is funnelform inlet point 5, and the lower end of shell 8 is funnelform discharging opening 7, is inner chamber 6 in the shell 8, is provided with star wheel rotor in inner chamber 6, and this star wheel rotor is connected with transmission shaft 4 on being installed on shell 8; On described inlet point 5 a side inwall identical, several boss are set with the star wheel rotor rotation direction.Figure 1 shows that the state that star wheel rotor clockwise direction (seeing shown in the arrow among the figure) rotates, at this moment material all enters in the inner chamber 6 from the right side of inlet point 5, and therefore, described boss must be arranged on the right side inwall of inlet point 5.
Described boss is a V-arrangement boss 3.Distance between described boss is L1, and the wide of boss is L2, and long is t; The lower end diameter of described inlet point 5 is T, and T＞t.Be outside equipped with one deck outer casing 2 at described shell 8.In described star wheel rotor, several baffle plates of arranging radially 9 evenly are set on runner, described baffle plate 9 all passes the center of circle of runner.
For ease of making and installing, described boss is put together by two triangle cushion blocks; The bottom surface of two triangle cushion blocks is all identical with the inwall of inlet point 5, and the top margin of two triangle cushion blocks is fitted mutually; The section of two triangle cushion blocks is all triangular in shape.
The present invention is when work, and powder-material enters inner chamber 6 by inlet point 5, and the star wheel rotor rotating speed is certain, then plays the effect of dosing.According to P=F/S, the seamed edge of V-arrangement boss 3 produces very high pressure, can smash the powder that has formed piece, thereby feed is smooth and easy.
In addition, increase V-type boss 3 and help also to prevent that star wheel rotor is stuck.Because the existence of V-type boss 3, powder-material is inner cavity filled 6 with the form of three bursts of materials flows, and three bursts of materials flows are separated by V-type boss 3, and then the result is: inner chamber 6 has the space, and is more open between particle.Under the situation that star wheel rotor rotates, powder-material will produce centnifugal force, powder-material in the inner chamber 6 is big to the pressure that shell 8 produces, thereby it is also big with the friction force of shell 8, because it is gapped between powder-material, mobility is good, and the powder-material that rubs with shell 8 can in time leave, and then star wheel rotor can be not stuck by powder-material.
