Embodiment
As shown in Figure 1, a specific embodiment of the present invention, solid-state organic waste aerobic fermentation air blast distribution device comprises cloth air drain 1, ventilative cover plate 2, air-supply duct 3, drainage tray 4, ventilative base plate 5 and washing unit 6.
Wherein, air-supply duct 3 connects with cloth air drain 1, ventilative cover plate 2 is covered in the notch of cloth air drain 1, drainage tray 4 is arranged on the bottom of cloth air drain 1, washing unit 6 is arranged in the cloth air drain 1, ventilative base plate 5 is arranged on the washing unit 6, is provided with between ventilative cover plate 2 and the ventilative base plate 5 to make air feed scatter uniform packing layer.
As shown in Figure 1, solid-state organic waste aerobic fermentation air blast distribution device in the present embodiment, include but not limited to be applied in the reactor of various requirement air blast gas distribution, exemplary, present embodiment is the distribution device that is applied in the solid-state organic waste aerobic fermentation groove, to the oxygen supply of ventilating of the fermentation reaction of solid-state organic waste, described solid-state organic waste is stacked on the ventilative cover plate 2.
Be provided with several washing units 6 by wash tub pipe 9 series connection in the cloth air drain 1 in described reactor, washing unit 6 evenly is fixedly installed in the cloth air drain 1, be provided with ventilative base plate 5 between two adjacent washing units 6, all ventilative base plates 5 are provided with packing layer 7 between ventilative base plate 5 and ventilative cover plate 2 on a horizontal plane.
When air-supply duct 3 beginning air feed, gas enters cloth air drain 1, because isolation and the barrier effect of ventilative base plate 5 and packing layer 7, gas at first is full of the cloth air drain 1 of the below that is in ventilative base plate 5, increase gradually along with cloth air drain 1 internal gas pressure, gas up overflows by ventilative base plate 5, enters packing layer 7, further even gas distribution; Because in the air feed process, packing layer 7 and ventilative base plate 5 are stopped up by the top windrow through regular meeting, influence the effect of ventilation oxygen supply greatly, so must in time clear up it.
At this moment, only need open washing unit 6, rinse water will spray simultaneously on packing layer 7 and ventilative base plate 5, carries out the cleaning of fs; Obviously, by the adjusting of washing unit 6 aquifer yields and drainage tray 4 water displacement, can control the elevation of water surface in the cloth air drain 1, make water level cover ventilative base plate 5 and packing layer 7, realize the cleaning of subordinate phase; Last re-adjustment cleaning device aquifer yield and drainage tray 4 water displacement are discharged sewage, finish once and clean, and certainly, can also carry out repeatedly wash cycles as required.
This shows that the simple structure of present embodiment, flexible realizes that not only the ventilation oxygen supply is even, can also clean automatically distribution device in real time simultaneously, has lowered labor strength greatly, improved the efficient that aerobic fermentation is handled.
In addition, as Fig. 1 and Fig. 5, shown in this specific embodiment, the filler that adopts in the packing layer 7 is the plastics Ball-type packing, offer the long strip shape through hole adaptive with plastics Ball-type packing diameter on the ventilative base plate 5, further improve cleaning performance with evenly ventilative, certainly can also select the filler of other materials or shape, present embodiment is preferred plastic material, mainly be to utilize its density lower than water, when carrying out the subordinate phase cleaning, filler can be at water float, be not easy to be blocked on the ventilative base plate 5, make that the cleaning performance of ventilative base plate 5 and filler is better.
As shown in Figure 1, in this specific embodiment, cloth air drain 1 bottom surface is set to the scarp, and drainage tray 4 is arranged on described scarp bottom, and drainage tray 4 external delivery pipes 8 are convenient to cloth air drain 1 and are carried out draining completely.
As shown in Figures 2 and 3, in this specific embodiment, used washing unit 6 comprises rinse water joint 61, washing cap 62, and H type bracing frame 63, and for the liftable supporter 64 that supports ventilative base plate 5; H type bracing frame 63 is hollow support frame, and rinse water joint 61 runs through the hollow space of H type bracing frame 63, and upper end and described hollow space that washing cap 62 is arranged on H type bracing frame 63 connect, and also are provided with the syringe pipe 65 for the flushing water outlet on the washing cap 62; Liftable supporter 64 is arranged on the hollow space of H type bracing frame 63.
At present embodiment, rinse water pours into the hollow space of H type bracing frame 63, and rinse water is last only to be sprayed from syringe pipe.
As shown in Figure 1, in this specific embodiment, a plurality of washing units evenly are arranged in the cloth air drain 1, ventilative base plate 5 as shown in Figure 5 is arranged on the liftable supporter 64 of adjacent washing unit, the rinse water joint 61 of washing unit 6 is connected on the wash tub pipe 9, to being in the washing unit of cloth air drain 1 two ends, can be according to the distance of the whole story two ventilative base plates 5 and cloth air drain 1 two ends, the cushion block of each adaptive block length bar shaped on liftable supporter 64, two ends is sealed, avoid filler to be spilt by two ends.
As shown in Figures 2 and 3, liftable supporter 64 comprises: upper piston 641, lower piston 642, connecting rod 643, spring 644, fixed link 645 and the back up pad 646 that is connected with ventilative base plate 5; Upper piston 641 is arranged on the upper end of connecting rod 643, lower piston 642 is arranged on the lower end of connecting rod 643, upper piston 641 and lower piston 642 are movably connected on the described hollow space of H type bracing frame 63, back up pad 646 is fixed on the connecting rod 643, one end of described spring 644 is arranged on the lower surface of described back up pad 646, and an other end is fixed on described H type bracing frame 63.
As shown in Figure 4, the center offers tie rod holes 647 on the back up pad 646, around tie rod holes 647, offer 4 fixed link holes 648, fixed link 645 passes fixed link hole 648 and is welded on the H type bracing frame 63, back up pad 646 is by tie rod holes 647 sheathed being weldingly fixed on the connecting rod 643, drive by connecting rod 643, slide up and down along fixed link 645.Upper piston 641 and lower piston 642 are done the piston motion in H type bracing frame 63.As shown in Figure 2, each washing unit 6 of present embodiment comprises on the right and left of the H type that is arranged on bracing frame 63 of 64, two liftable supporter 64 symmetries of two liftable supporters.
As shown in Figure 6, liftable supporter 64 has two working ordeies, is washing unit 6 not during water flowing in a of Fig. 6 figure, and liftable supporter 64 is in high-order working state figure; When in the b of Fig. 6 figure, being washing unit 6 water flowings, liftable supporter 64 is in the working state figure of low level, and at this time owing to water flowing, hydraulic pressure has a downward pressure to upper piston 641, spring 644 is further compressed, thereby realize the automatic decline of liftable supporter 64 positions.Because the decline of liftable supporter 64, drive the synchronous decline of ventilative base plate 5 positions, made that the space between ventilative cover plate 2 and the ventilative base plate becomes big, be in the packing layer 7 in this space also along with becoming more fluffy, impel whole wash phase to become more efficient, cleaning performance is better; After wash phase finished, spring 644 resetted, and liftable supporter 64 rises to original position automatically.
Exemplary, the operational applications of this specific embodiment may further comprise the steps:
