Abstract
The utility model discloses a changeable spoke type screen cylinder which belongs to paper manufacturing machinery and especially indicates a screen cylinder of a pressure pulp cleaner for processing paper pulp. The changeable spoke type screen cylinder comprises a screen cylinder frame and spokes. The structure of the changeable spoke type screen cylinder is as follows: the upper ring of the screen cylinder frame and at least three middle rings and lower rings of a cylinder rim are parallel mutually and are orderly arranged to be fixed and connected by fasters which are parallel with the rings. Spoke installing slots at the inner sides of the middle rings of the cylinder rim are uniformly arranged rectangles, and the spoke with T-shaped section are installed inside the slots. The inner sides of the spokes are provided with at least three fixing slots. Annular elastic cup rings are installed inside the fixing slots. The spoke installing slots at the inner sides of the middle rings of the cylinder rim of the screen cylinder are rectangular slots, the spokes are installed inside the slots and then are fixed by elastic cup rings, when the spoke abrasion enlarges screen cuts beyond the technical requirement, the screen cylinder can be repaired by the method of changing new spokes, and the screen cylinder can be recycled for multiple times and is a demountable structure, thereby being convenient for processing and installing and being capable of reducing the using cost of the screen cylinder.
Description
Technical field
The utility model belongs to papermaking equipment, particularly the screen cylinder of the pressure pulp screen that paper pulp is handled.
Background technology
Pressurized screen and selectifier are the main screening installation of paper-making pulping, and its screen cylinder is that all steel is made, and processing and material cost are higher.Price little about several thousand yuan; Large-scale screen cylinder several ten thousand is the integral solder structure to tens0000 yuan, and thermal stress that welding occurs and crator also can cause operation to be interrupted owing to screening plant is in use loaded.This loading can be got dead load or circulation and be added my form, can be because of the tired fault that cause.The also possible hook of crator is lived the fiber of suspension, causes mesh screen or filter screen to stop up gradually, or forms extremely harmful what is called " string of a musical instrument " in use.Big because of the screening wearing and tearing in addition, sealing weares and teares easily, and wearing and tearing just need integral replacing above the effect that just loses screening after the specification requirement, cause big waste.CN101006225A discloses method that a kind of employing expands with heat and contract with cold spoke has been fixed on method on the drum circle, though the shortcoming that has overcome welding still can't be in sieve seam wearing and tearing back replacing spoke separately.
The utility model content
Using the deficiency that can't change spoke after seam weares and teares separately to sieving in order to overcome existing screen cylinder, the purpose of this utility model provides a kind of replaceable spoke type screen cylinder, and this replaceable spoke type screen cylinder can be changed spoke separately easily after the sieve seam weares and teares.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of replaceable spoke type screen cylinder, comprise screen cylinder framework, spoke, it is characterized in that: going up of screen cylinder framework enclosed, at least three roads rouse to encircle in the circle with enclosing parallel to each other down and being arranged in order by perpendicular fixture and fixedly connected, the inboard spoke mounting groove of ring is evenly distributed rectangle in the described drum circle, the cross section is being installed in the groove of spoke of T font, the spoke inboard has three road holddown grooves at least, and the ring spring packing is installed in the holddown groove.
The screen cylinder framework go up in circle, the three roads drum circle ring at least and circle is parallel to each other and be arranged in order by perpendicular arc fixed plate bar welding fixing down.
Going up of screen cylinder framework enclosed, at least three roads rouse to encircle and enclose down parallel to each other in the circle and be arranged in order by perpendicular screw rod and nut and fix, and screw jacket has at least two spacer sleeves, and the spacer sleeve two ends are equipped with to rouse in the circle and encircle.
The inboard spoke mounting groove of ring is evenly distributed rectangular channel in the drum circle of the disclosed replaceable spoke type screen cylinder of the utility model, spoke is installed in the groove and fixes with circumferential ring expander, when service time, length caused the sieve seam to strengthen above specification requirement because of the spoke wearing and tearing, can adopt and take off circumferential ring expander and unload the spoke that is worn, the method that more renews spoke is repaired screen cylinder, the screen cylinder framework can be repeatedly used, the screen cylinder framework is last circle in addition, following circle, ring in the drum circle, the demountable structure that spacer sleeve is fixed up with screw rod and nut, process easy for installation, can economize on resources, reduce the screen cylinder use cost.
