Description
Technical field
The utility model relates to the soil discharging valve in the sewage treatment flow process, relates in particular to concealed soil discharging valve.
Background technique
processing at Sludge in Sewage Treatment is a very important link, in prior art, the general gravity spoil disposal method that adopts, on the storage bucket in each single pond of deposition tank, telescopic soil discharging valve is set, static pressure by water is discharged mud, this telescopic soil discharging valve, comprise inner core and urceolus, while due to the too high structure problem soil discharging valve of stack shell, all opening, static head is too small, cause return sludge ratio little, limited sludge back flow quantity, the difference of the sludge quantity of taking away less than the sludge quantity that enters deposition tank and water outlet due to sludge back flow quantity, cause the deposition tank mud that accumulates gradually, after the deposition tank sludge blanket is too high, a large amount of activated sludge flow out with water outlet, make deposition tank mud again reach a dynamic balancing, make the water quality variation of handling outflow well, and the cross-arm of lifting is installed in inner core soil discharging valve outlet diameter direction, when soil discharging valve is opened, thread foreign material in sewage sludge are under the effect of static head, reversal of the natural order of things is on cross-arm, in the course of time the foreign material on cross-arm are more and more, blocked the soil discharging valve outlet, cause the sludge reflux amount to reduce, affect effluent quality.
Summary of the invention
Technical problem to be solved in the utility model is: the concealed soil discharging valve that a kind of static head is large, the sludge reflux amount is large, the soil discharging valve outlet does not have foreign material, effluent quality is good is provided.
for solving the problems of the technologies described above, concealed soil discharging valve of the present utility model is by the following technical solutions: concealed soil discharging valve, comprise the sludge drainage pipe that connects with deposition tank storage bucket, be provided with the up and down hollow tubular inner core of sludge drainage pipe relatively in sludge drainage pipe, has gap between described sludge drainage pipe and inner core, described inner core top is provided with the circular seal cover plate, described inner core and sludge drainage pipe connect, the circular seal cover plate diameter impels inner core to have circular spacing chimb greater than the sludge drainage pipe diameter, the end face butt of the bottom surface of the spacing chimb of inner core and sludge drainage pipe is sealed and matched, be fixedly installed lifting bar on the circular seal cover plate, the inner core sidewall offers the spoil disposal through hole, described sludge drainage pipe length is greater than inner core length.
the beneficial effect of the concealed soil discharging valve of the utility model is: by improvement, reduced the soil discharging valve whole height, the spoil disposal via height of soil discharging valve is reduced greatly, and the spoil disposal through hole is arranged on the inner core side and has reduced equally the height of spoil disposal through hole, cause the spoil disposal through hole more lower than the height of the deposition tank water surface, thereby make static head larger, spoil disposal is more strong, make sludge back flow quantity greater than the sludge quantity that enters deposition tank, can not pile up mud in deposition tank, mud can be along with current flow out, affect effluent quality, there is not the lifting crosspiece in this improved soil discharging valve through hole, foreign material can not hang over and promote on crosspiece, thoroughly solved spoil disposal through hole blockage problem, guarantee that sludge stream is clear and coherent smooth, be sealed and matched by the bottom surface of the spacing chimb of inner core and the end face butt of sludge drainage pipe, be in while closing at soil discharging valve, prevent that sewage sludge from flowing out from the gap between sludge drainage pipe and inner core, and circular spacing chimb plays position-limiting action, prevent that whole inner core from dropping to the sludge drainage pipe the inside.
The utility model provides the technological scheme of improved concealed soil discharging valve to be: described sludge drainage pipe top is provided with circular sealed convex edge, the end face butt of the bottom surface of the spacing chimb of inner core and sludge drainage pipe sealed convex edge is sealed and matched, by circular sealed convex edge is set on sludge drainage pipe, the area that the end face butt of the bottom surface of the spacing chimb of inner core and sludge drainage pipe sealed convex edge is sealed and matched is larger, sealing effect is better, prevents that better sewage sludge from flowing out from the gap between sludge drainage pipe and inner core.
The utility model provides the further technological scheme of improved concealed soil discharging valve to be: the end face of described circular sealed convex edge is provided with rubber sealing ring, the rubber sealing ring butt of the bottom surface of the spacing chimb of inner core and sludge drainage pipe sealed convex edge end face is sealed and matched, by add rubber sealing ring between spacing chimb and sealed convex edge, make tightr that spacing chimb and sealed convex edge butt be sealed and matched, better prevent from flowing out the gap of sewage sludge between spacing chimb and sealed convex edge, and simple in structure, easy manufacturing, cost are low.
The utility model provides the technological scheme of an improved concealed soil discharging valve of step again to be: described spoil disposal through hole is circular spoil disposal through hole, circular spoil disposal through-hole diameter and inner diameter of steel flue be size on an equal basis, the circular spoil disposal through hole of this size makes the sludge volume reflux ratio reach best, can not affect because circular spoil disposal through hole is excessive the global stability of inner core, inner core can be out of shape in running, also can not make return sludge ratio too small because circular spoil disposal through hole is too small.
The utility model provides the further technological scheme of improved concealed soil discharging valve to be: described inner core, circular seal cover plate, lifting bar are formed in one, make between inner core and circular seal cover plate and between circular seal cover plate and lifting bar and there is no connection welding, thereby make soil discharging valve integral body more firm, the corrosivity of mud and sewage is stronger, do not have connection welding can avoid allowing soil discharging valve use more of a specified duration from joint corrosion soil discharging valve.
