Embodiment
Below in conjunction with specification drawings and specific embodiments to invention explanation further.
The present invention comprises vapour condensation device and prolong cleaning plant.
As shown in figs. 1 and 4, condensing works described in embodiment 1 comprises prolong 2 and condensation pipe 11, the wall at the two ends of the cavity of described condensation pipe 11 is installed with card and buckles 9, card button 9 is provided with card groove, the pipeline of described prolong 2 both sides is stuck in the card groove that card buckles 9, and prolong 2 liquid inlet and outlet pipe passes from the through hole condensation pipe 11 sidewall respectively. In prolong be full of liquid, it is possible to be lasting cold water, the cold water after heat exchange can be directly output as industry link use hot water, it is achieved heat reuptake utilization
. The both sides of the lower wall of described condensation pipe 11 are provided with oil groove, and the mid-way of each oil groove of condensation pipe 11 is also provided with a threaded hole, and threaded hole is threaded with sealing nut 17.Its effect is, makes the easy volatile oil under brushing from prolong 2 fall in oil groove, when the greasy dirt in oil groove fills, then backs out sealing nut 17 and is discharged by easy volatile oil.
As shown in Figure 6, described prolong 2 is ellipse spiral shape condensing coil.
Between the both sides senior middle school of described oil groove low, enable so easily volatilize greasy dirt easier flow in the middle of low-lying place, then from threaded hole discharge.
As shown in figs. 1 and 3, described prolong cleaning plant comprises suction fan 15, back and forth leading screw 5, flat brush and brush roll 3.
Described suction fan 15 is prior art, and its concrete structure just repeats no more, and the air draught pipe of suction fan 15 and one end of condensation pipe 11 are bolted, and described suction fan 15 is provided with a sealing-ring with condensation pipe 11 junction. The sidewall of the both sides of the air draught pipe of described suction fan 15 is respectively equipped with a bearing hole, in described bearing hole, bearing is installed. The two ends of described reciprocal leading screw 5 are each passed through wind wheel 14 and match with bearing, and wind wheel 14 is fixedly mounted on the two ends of reciprocal leading screw 5, and feed screw nut 6 is enclosed within reciprocal leading screw 5. When reciprocal leading screw 5 rotates, feed screw nut 6 can move reciprocatingly on reciprocal leading screw 5. The convex part of the centre of described feed screw nut 6 is fixedly connected with joint sleeve 20, joint sleeve 20 and coupling shaft 7 are for being rotatably connected, mode of connection in this scheme is: be provided with a notch cuttype through hole in described joint sleeve 20, the large diameter hole of one end of described notch cuttype through hole is bearing hole, and bearing is provided with bearing in hole. One end of described coupling shaft 7 and bearing are shrink-fit, and such coupling shaft 7 can not come off from the bearing hole of bearing. One end and the bearing end cap 19 of described joint sleeve 20 are connected by screw. Described coupling shaft 7 is connected by key with gear 8, and described gear 8 is meshed with tooth bar 4, and the two ends of described tooth bar 4 are fixedly connected with the inwall of suction fan 15 air draught pipe both sides. The other end of described coupling shaft 7 is fixedly connected with one end of the roller bearing of brush roll 3, and the hairbrush in brush roll 3 can touch prolong 2 and carry out cleaning oil pollution. The both sides up and down of described joint sleeve 20 are installed with upper connecting rod 13 and lower connecting rod 21 respectively. Described flat board is brushed with two, is respectively upper flat plate brush 12 and lower flat brush 16. One end of described upper connecting rod 13 is fixedly connected with one end of upper flat plate brush 12 is vertical, lower connecting rod 21 one end is fixedly connected with one end of lower flat brush 16 is vertical, described prolong 2 is between brush roll 3 hairbrush and flat brush hairbrush, and prolong 2 can be cleared up by said brush. The lower end of described lower flat brush 16 is fixedly connected with scraper plate 18, and scraper plate 18 can do straight reciprocating motion with reciprocal leading screw 5, is scraped by the oil stain fallen on condensation pipe 11 inner chamber lower end wall in the oil groove of condensation pipe 11 both sides.
Described scraper plate 18 is rectangular rubber scraper plate, owing to rubber flap has certain elasticity, is blown off by oil stain so rubber flap 18 fully can be fitted with the lower end inner wall of condensation pipe 11, and not easily scratches condensation pipe 11.
During embodiment 1 operates for small-sized smoke evacuation exhaust, for large-scale passage, owing to prolong 2 and condensation pipe 11 are all long, brush roll 3, upper flat plate brush 12 are also corresponding longer to lower flat brush 16, rotation process easily occurs violent swing, breaks prolong 2.
Embodiment 2 has improved on the structure basis of embodiment 1, add following structure: as shown in figures 2 and 5, the air inlet of described condensation pipe 11 installs pulley retaining plate 1, the both sides of described pulley retaining plate 1 are fixedly connected with the two side of the air inlet of condensation pipe 11, the center of pulley retaining plate 1 is provided with a rectangular through holes, the upper and lower hole wall of rectangular through holes is provided with chute, being embedded with a pulley 10 between two chutes, the two ends up and down of described pulley retaining plate 1 are also respectively equipped with a chute.The described the other end of brush roll 3 roller bearing is fixedly connected with the centre hole of pulley 10. Described pulley 10 is embedded in the chute of pulley retaining plate 1, is possible not only to feed screw nut 6 is played guide effect, and is possible to prevent brush roll 3 violent swing occurs in rotation process, breaks prolong 2. Described upper flat plate brush 12 is fixedly connected with a slide block 22 respectively with the other end of lower flat brush 16, and described slide block 22 is embedded in the chute at pulley retaining plate about 1 two ends respectively.
Operating process is as follows: when using of the present invention, first starts suction fan 15, the steam produced is sucked in condensing works in chemical industry or pharmaceutical preparation process, and when steam is in condensation process, the volatile oil of low melting point is attached on prolong 2. owing to the effect of suction fan 15 produces air current flow, driven wind wheel 14 high-speed rotation of suction fan 15 air draught pipe inside by air current flow, then drive reciprocal leading screw 5 to rotate, make joint sleeve 20 drive brush roll 3 to do straight reciprocating motion by coupling shaft 7. while brush roll 3 does straight reciprocating motion, due to the effect of gear 8 with tooth bar 4, coupling shaft 7 limit can be made to do translational motion limit rotate, easy volatile oil on the lower prolong 2 of the brush can being more prone to like this, meanwhile, reciprocal leading screw 5 drives upper and lower flat brush 16 to do straight reciprocating motion, the oil stain on tube wall outside the upper and lower of cleaning prolong, oil stain under brushing from prolong 2 is fallen on the wall of the condensation pipe 11 lower end of inner chamber, then by scraper plate 18 oil stain scraped in the oil groove of condensation pipe 11 both sides, then sealing nut 17 is opened, oil stain is discharged from threaded hole.
It should be noted that; the particular of the present invention is to invention has been detailed description; for a person skilled in the art, the various apparent change it carried out when not deviating from the spirit and scope of the present invention is all within protection scope of the present invention.
