In the embodiment of the present invention, the outer wall of each material transporting pipe 23 can be distributed with micropores 23f, and the aperture of each micropore 23f is smaller than the size of sand.
By adopting the technical scheme: cleaned sand can be added into the recovery box body through the feeding hole, and the feeding main pipe and the distribution cylinder distribute the entering wet sand into the conveying channels, so that the sand loses moisture in the conveying channels (through micropores); secondly, when the sand moves in the material conveying channel (due to the inclined arrangement of the material conveying pipe), the sand can be contacted with the outer wall of the heat energy pipe in the material conveying channel, hot gas can be introduced into the heat energy pipe to dry the sand (the purpose of water evaporation is achieved), compared with the traditional drying method, the drying efficiency is far higher than that of the traditional drying method (namely, the sand can be uniformly dried or scattered, but not only the surface of a sand pile is dried), and the drying time is one third of that of the traditional drying method under the condition that the sand amount is the same through statistics;
in more detail:
referring to fig. 1 to 3, sand to be dried and recovered may be added into a box through a feed inlet, and transferred into a distribution barrel through a feed main pipe communicated with the feed inlet, the sand entering the distribution barrel enters a transportation channel through a refining pipe communicated with the distribution barrel (refer to fig. 1 to 2), and when the sand moves in the transportation channel, the sand may contact with a heat pipe disposed in the transportation channel, and hot gas (for example, industrial waste hot gas) may be introduced into the heat pipe, and the heat energy of the industrial waste hot gas is transferred to the sand through the heat pipe, so as to heat the sand, and further dry the sand, and finally, the dried sand may be discharged from an output end of the transportation pipe (and may be dried in the sun at a later stage), so as to uniformly heat the sand and reduce the moisture of the sand (even in a case of directly drying the sand), in the subsequent process of drying the glass by sunlight, the drying efficiency of the glass can be improved;
it should be noted that:
firstly, due to the wet sand fed from the feed inlet, which has the possibility of caking, the sand-crushing module provided in the distribution cylinder can "crush" the caked sand, that is: the first motor drives the first transmission shaft to drive the sand crushing group (namely, the sand crushing shaft and the sand crushing block) arranged outside the first transmission shaft to impact sand, so that the caked sand can be dispersed, the sand can be uniformly heated when entering the material conveying pipe, and the sand drying effect of the sand conveying pipe is ensured; secondly, the purpose of setting the sand breaking blocks into a crescent shape is to improve the impact strength (because the two ends of the crescent shape are tips) of the sand breaking blocks on a sand bag (namely, agglomerated sand), thereby improving the crushing effect on the sand bag;
secondly, the purpose that the broken sand axle dislocation set between adjacent broken sand group is: the contact frequency of distributing inward sand by the sand crushing team can be improved, and the sand crushing efficiency is further improved;
thirdly, because moist sand has certain viscidity, in order to guarantee its removal effect in fortune material passageway, has set up in fortune material pipe top and has pushed away the material module, promptly: the pushing part is driven to move by the second motor, and the sand in the refining channel is pushed (namely, the sand is pushed to the output end of the material conveying channel by the transverse pushing plate), so that the moving effect of the sand is ensured; secondly, the concave part that sets up on the horizontal scraping wings can be used to the heat energy pipe activity to in order to improve the material effect of pushing away of horizontal scraping wings to sand, set up the material pushing block in each concave part, promptly: because the movement of the transverse material pushing plate is circumferential movement, the volume of the concave part is inevitably larger than the diameter of the section of the heat energy pipe when the transverse material pushing plate rotates, and therefore, the arranged material pushing block can be in contact with the outer wall of the top of the heat energy pipe when the transverse material pushing plate pushes sand through the action of the compression spring, sand at the top of the heat energy pipe can be pushed, and the material pushing effect is further ensured (refer to fig. 3);
fourthly, the thickness of the material pushing block is changed, so that the contact area between the material pushing block and sand is increased while smooth movement of the material pushing block is ensured, and further the sand pushing effect can be further improved;
fifthly, the micropores arranged on the material conveying pipe can be used for discharging moisture, so that the moisture or (moisture) discharging efficiency is improved, and the size of each micropore is smaller than that of sand so as to avoid sand leakage.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
