Description
Technical field
The utility model relates to a kind of sleeve pipe cleaning backstay device.
Background technology
In ultraviolet sterilizer, cleaning of retaining sleeve, is reduce the stop of ultraviolet in irradiation process, improves ultraviolet light transmittance, guarantee the important guarantee of ultraviolet sterilization ability.For this reason, the cleaning for the sleeve pipe outside quartz burner is extremely important.Cannula cleaning is exactly axially reciprocating along sleeve pipe with the cleaning sheet be wrapped in outside sleeve pipe, is washed away by flowing water by the dirt under cleaning sheet wiper, thus makes sleeve pipe keep clean.
For many fluorescent tubes ultraviolet sterilizer, complete the action of cannula cleaning, be absolutely not part easy thing.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of sleeve pipe cleaning backstay device being convenient to clean many fluorescent tubes ultraviolet sterilizer sleeve pipe.
The purpose of this utility model is achieved in that
A kind of sleeve pipe cleaning backstay device, it comprises the cylindrical shell of lateral arrangement, the two ends, left and right of cylindrical shell are respectively arranged with left cover and right cover plate, the axis of cylindrical shell is provided with a rhizoid bar, screw mandrel is provided with the vertical push-and-pull dish arranged, two positioning and guiding bars are arranged with in parallel between described left cover and right cover plate, the two ends, left and right of positioning and guiding bar are provided with screw thread, the two ends, left and right of positioning and guiding bar are stretched out outside cylindrical shell, the two ends, left and right of positioning and guiding bar are revolved from outside to inside and are put nut and left cover and right cover plate and be locked, push-and-pull dish is provided with two location rod aperture, two positioning and guiding bars are through location rod aperture.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts the two positioning and guiding pole pair push-and-pull dishes stretched to lead, and linearity is good, and the layout of two positioning and guiding bars can make left cover and the decompression of right cover plate, improves service life.Therefore this sleeve pipe cleaning backstay device has the advantage of being convenient to clean many fluorescent tubes ultraviolet sterilizer sleeve pipe, improves the service life of many fluorescent tubes ultraviolet sterilizer sleeve pipe.

Detailed description of the invention
See Fig. 1 ~ Fig. 2, a kind of sleeve pipe cleaning backstay device that the utility model relates to, it comprises the cylindrical shell 1 of lateral arrangement, the two ends, left and right of cylindrical shell 1 are respectively arranged with left cover 2 and right cover plate 3, the axis of cylindrical shell 1 is provided with a rhizoid bar 4, the left end of screw mandrel 4 is connected on the screw rodb base of left cover 2 right side, the right-hand member of screw mandrel 4 stretches out right cover plate 3, two positioning and guiding bars 5 are arranged with up and down in parallel between described left cover 2 and right cover plate 3, the two ends, left and right of positioning and guiding bar 5 are provided with screw thread, the two ends, left and right of positioning and guiding bar 5 are stretched out outside cylindrical shell 1, the two ends, left and right of positioning and guiding bar 5 are revolved from outside to inside and are put nut and left cover 3 and right cover plate 4 and be locked.Multiple sleeve pipe be arranged in parallel also is provided with between left cover 2 and right cover plate 3, quartz burner is provided with in sleeve pipe, screw mandrel 4 is provided with the vertical push-and-pull dish 6 arranged, push-and-pull dish 6 is provided with collar aperture 6.1 and location rod aperture 6.2, multiple sleeve pipe is through collar aperture 6.1, and positioning and guiding bar 6 is through location rod aperture 6.2.Push-and-pull dish 6 is provided with cleaning sheet.
On the push-and-pull dish that being first fixed on of floating of cleaning sheet can will be kept vertical all the time with sleeve pipe.The push-pull effort acted on push-and-pull dish derives from screw mandrel.Push-and-pull dish is moved in parallel perpendicular to sleeve pipe, be unable to do without at least two positioning and guiding bars.Positioning and guiding bar plays a part very crucial in whole sleeve pipe cleaning process.
The condition that positioning and guiding bar must possess: first, the out-of-roundness of guide post itself and linearity must wrap just in prescribed limit.Secondly, enough rigidity be had.Smooth surface, anti-corruption ability is strong, reduces coefficient of friction as far as possible.And possess reliable mounting means, prevent from leaking.According to above-mentioned analysis, we select stainless steel 304 material, and through grinding, two ends are provided with screw thread, and structure as shown in the figure.This method of attachment, eliminates the possibility of slender rod piece unstability when pressurized.Elongate rod adopts tension to connect, and can play the positive energy of slender rod piece, also serve Reduction of Students' Study Load effect to after left cover and right cover plate pressurized simultaneously.After we use this guide post, because this rod member is under tension state, can reliable linearity be kept, therefore excellent characteristic played to the location of push-and-pull dish, guiding.
