Abstract
The utility model discloses a kind of novel sieve nest bolster, it comprises the framework that top is uncovered, and framework is comprised of base plate and side plate, and base plate is evenly equipped with the small opening that diameter dimension is 1 ~ 3mm, and the upper surface center of base plate is high, surrounding is low, and the junction of small opening and plate upper surface is provided with groove; The bottom outer wall of framework and the upper inside wall of sieve nest are suitable.The novel sieve nest bolster of the utility model can alleviate the weight of directly piling powder-deposit on sieve nest, and powder to be sieved is evenly distributed on sieve nest, thereby effectively suppress screen cloth, stops up.Novel sieve nest bolster also plays the effect that cushions powder impact power to be sieved in addition.This novel sieve nest bolster contributes to improve the service life of sieve nest and improves sifting efficiency.
Description
Technical field
The utility model relates to a kind of for sieving the device of powder, relates in particular to a kind of for sieving the sieve nest bolster of the powder such as polytetrafluoroethyldispersion dispersion resin.
Background technology
It is mainly to adopt to push moulding process that existing polytetrafluoroethylene (PTFE) pipe fitting is produced, the step such as need batch mixing, precompressed, push.Before batch mixing, to the polytetrafluoroethylene powder processing of sieving, screen the wherein polytetrafluoroethylpowder powder below certain fineness.Therefore, sieving machine is one of visual plant of producing polyfluortetraethylene pipe.The sifting efficiency of sieving machine sieve nest depends on the stopping state of screen cloth to a great extent; If screen cloth stops up, be difficult to improve screen effect.In addition, depend on the one hand the obstruction of screen cloth the service life of screen cloth, also depend on the other hand the impulsive force of the powder to be sieved that screen cloth is subject to.If powder charging rate to be sieved is fast, feed pipe is large apart from screen cloth distance, can produce huge impulsive force to screen cloth, screen cloth is easy to corrupted.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of and can effectively overcome the screening powder sieve nest bolster that screen cloth stops up, improves screen life-span.
For this reason, the technical solution of the utility model is a kind of novel sieve nest bolster, it comprises the framework that top is uncovered, framework is comprised of base plate and side plate, base plate is evenly equipped with the small opening that diameter dimension is 1 ~ 3mm, and the upper surface center of base plate is high, surrounding is low, and the junction of small opening and plate upper surface is provided with groove; The bottom outer wall of framework and the upper inside wall of sieve nest are suitable.
Preferably, described groove is arc groove.
Further preferably, described arc groove and described plate upper surface are rounding off.
Preferably, the upper surface of described base plate is the conical surface; The lower surface of base plate is plane.
Further preferably, the upper surface of described base plate is taper seat.
Further preferably, the lower surface of described base plate is provided with reinforcement.
The bottom outer wall of described framework can fasten with the upper inside wall of described sieve nest.Or the bottom outer wall of described framework and the upper inside wall of described sieve nest are threaded connection.
Advantage of the present utility model and beneficial effect are: the utility model sieve nest bolster can alleviate the weight of directly piling powder-deposit on sieve nest, and powder to be sieved is evenly distributed on sieve nest, thereby effectively suppress screen cloth, stop up.Novel sieve nest bolster also plays the effect that cushions powder impact power to be sieved in addition.This novel sieve nest bolster contributes to improve the service life of sieve nest and improves sifting efficiency.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the utility model sieve nest bolster;
Fig. 2 is the another kind of structural representation of the utility model sieve nest bolster.
In figure: 1, base plate; 2, side plate; 11, small opening; 12, groove; 13, reinforcement.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
The utility model is a kind of novel sieve nest bolster, and as shown in Figure 1, it comprises the framework that top is uncovered, framework is comprised of base plate 1 and side plate 2, base plate 1 is evenly equipped with small opening 11, and the upper surface center of base plate 1 is high, surrounding is low, and small opening 11 is provided with groove 12 with the junction of base plate 1 upper surface.Groove 12 is preferably arc groove 12, and arc groove 12 is rounding off with base plate 1 upper surface.
The bottom outer wall of framework and the upper inside wall of sieve nest are suitable; Upper inside wall that can sieve nest such as the bottom outer wall of framework fastens, or the bottom outer wall of framework can be threaded connection with the upper inside wall of sieve nest, both increased the connectivity robustness of sieve nest bolster and sieve nest, avoid producing and departing from wait sieving powder sieve nest bolster and sieve nest when sieve nest bolster falls into sieve nest, cause the unexpected material that leaks; When needs clean sieve nest bolster or sieve nest, can also dismantle both clean.
During use, the bottom of sieve nest bolster and the top of sieve nest fix, feed pipe be installed on sieve nest bolster directly over, wait sieving powder, from feed pipe, after sieve nest bolster buffering, enter again sieve nest; When sieving powder and reach base plate 1 upper surface of sieve nest bolster, from base plate 1, mind-set surrounding moves, and can be distributed in rapidly on the base plate 1 of sieve nest bolster, and then can be dispersed on screen cloth along small opening 11; Groove 12 can be stored the powder to be sieved of a part, the powder dropping amount of the small opening 11 that raising is near apart from base plate 1 center, thereby make powder to be sieved fall to more equably on screen cloth, the motion that while groove 12 is treated sieve powder produces certain retardation, avoid powder to be sieved to glide too fast to surrounding along base plate 1 upper surface, cause the powder of surrounding to pile up, thereby powder to be sieved can be fallen on sieve nest more equably.Adopt arc groove 12 can make powder to be sieved more smooth and easy from small opening 11 blankings.
Here, for for sieving the powder such as polytetrafluoroethyldispersion dispersion resin, the diameter dimension of small opening 11 is preferably 1 ~ 3mm, otherwise oversize, leaks material too fast, suppresses the effect that screen cloth stops up not ideal enough, too small, and screening efficiency is low.
Wherein, the upper surface of base plate 1 is preferably the conical surface, especially taper seat; Like this from feed pipe enter the powder to be sieved of sieve nest bolster can be in base plate 1 mind-set surrounding distribute more equably powder to be sieved so that along small opening 11 blankings, be evenly distributed on screen cloth.
The lower surface of base plate 1 is preferably plane; Due in the middle of base plate 1 over against feed pipe, therefore mid portion is large compared with the surrounding power that partly withstands shocks, this thick middle, the base arrangement that surrounding is thin had both guaranteed good load bearing effect, can reduce again the burden of sieve nest bolster to sieve nest.As improvement, can also add at the lower surface of base plate 1 reinforcement 13 to improve the ability that withstands shocks of sieve nest bolster, as shown in Figure 2.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
