Abstract
The utility model discloses a constant feeder, and the constant feeder comprises a casing. A material inlet and a material outlet are arranged on the casing; a spiral axle is arranged in the casing and is provided with spiral leaves, and the spiral leaves are in the form of single spirals at the material inlet end and double spirals at the material outlet end. The diameter of the spiral part of the spiral axle is larger than or equal to 1/5 of the outer spiral diameter. The constant feeding system of the utility model has low power consumption, rational and simple structure, low fragile part quantity, less maintenance as well as excellent controllability and stability of constant material feeding flows.
Description
The utility model relates to a kind of feeding device of powder material.
Powder material feeding devices such as existing common screw feeder, common impeller unloader, generally there are feed flow rate controllability and all relatively poor shortcoming of stability, and the dosing system consumption of power that is made of the dosing equipment that these feeding devices constitute is big, consumable accessory is many, and maintenance capacity is big.
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the permanent steady feeder of the controllability of permanent steady feed flow and good stability.
Technical solution of the present utility model is:
The steady feeder of a kind of perseverance, comprise casing, casing is provided with the charging and discharging mouth, dress screw shaft in the casing, dress spiral leaf on the screw shaft, the difference of itself and prior art is: the spiral leaf feed end on the screw shaft is the simple helix form, and discharge end is the double helix form, screw shaft the spiral part diameter is arranged more than or equal to 1/5 of spiral external diameter.
The planar development shape of discharging opening is L-shaped, and axial length is between between spiral external diameter and spiral external diameter four times, and upward and downward length is smaller or equal to the external diameter of spiral.
The consumption of power of the utility model dosing system is little, and is rational in infrastructure, simple, few easy workout part, and maintenance capacity is little, the controllability and the good stability of permanent steady feed flow.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the configuration diagram of screw shaft among Fig. 1.
Fig. 3 is the configuration diagram of casing among Fig. 1.
Fig. 4 is that the A of Fig. 3 is to view.
Fig. 5 is that the B of Fig. 3 is to view.
Fig. 6 is that the C of Fig. 3 is to view.
Fig. 7 is that the D of Fig. 3 is to expansion drawing.
Among the figure: 1, vee-pulley 2, V-belt 3, reductor 4, change-speed motor 5, drive coupling 6, bearing door 7, thrust ball bearing 8, left globe bearing 9, left end cap bearing seat 10, left seal cover cap 11, casing 12, screw shaft 13, right seal cover cap 14, right end cap bearing seat 15, right globe bearing 16, gland 17, support 18, axle 19, spiral leaf 20, casing left side flange 21, inlet point 22, the right flange 23 of casing, discharging opening.
Change-speed motor 4 drives the screw shaft 12 that is contained in the casing by vee-pulley 1, V-belt 2, reductor 4, drive coupling 5, dress spiral leaf 19 on the screw shaft 12, spiral leaf 18 feed ends on the screw shaft 12 are the simple helix form, discharge end is the double helix form, screw shaft 12 the spiral part diameter is arranged more than or equal to 1/5 of spiral external diameter.
The planar development shape of discharging opening 23 is L-shaped, and axial length is between between spiral external diameter and spiral external diameter four times, and upward and downward length is smaller or equal to the external diameter of spiral.
The discharging opening method for making is: get be less than or equal to spiral leaf height 1/8 for radius, with following and the left side is that circular arc tangential line is made semi arch, get and be less than or equal to spiral leaf height is done the right for distance parallel lines, get greater than spiral leaf height 1/4 length, with the bottom be base on the right the parallel lines intercepted length that makes progress be section, make this section and the tangent line of left side semi arch, get that to be less than or equal to spiral leaf height 1/2 length be that radius is done the lower right corner, the inscribe circular arc of the upper right corner and top and the right parallel lines angle removes the part formation discharging opening 23 that following top each line contains.
Claims (2)
1, the steady feeder of a kind of perseverance, comprise casing, casing is provided with the charging and discharging mouth, dress screw shaft in the casing, dress spiral leaf on the screw shaft, it is characterized in that: the spiral leaf feed end on the screw shaft is the simple helix form, and discharge end is the double helix form, screw shaft the spiral part diameter is arranged more than or equal to 1/5 of spiral external diameter.
2, the steady feeder of perseverance according to claim 1 is characterized in that: the planar development shape of discharging opening is L-shaped, and axial length is between between spiral external diameter and spiral external diameter four times, and upward and downward length is smaller or equal to the external diameter of spiral.
