Description
Technical field
This utility model belongs to sewage treatment area, relates to discharge of pipes field, a kind of air-prevention blocking valve for mud transport.
Background technology
In existing sewage disposal process, sludge dehydrating and drying process would generally be made for processing the mud of later stage residual.As shown in Figure 1, the way generally used in sludge dehydration process is, first will treat that the sewage sludge storage of mummification, in sewage sludge storage pond 90, then under the effect of spoil disposal motor 93, passes sequentially through discharge pipeline 91 and send mud pipe 92 to transport in the equipment of drying and other treatment to carry out dehydration and drying process；Wherein the first valve switch 94 is used for service conduits with the second valve switch 95.
But during this kind of operation, the mud stored due to sewage sludge storage pond 90 is the most, and it it is dehydration and drying after first storage；So after the mud in spoil disposal motor 93 exhausts sewage sludge storage pond 90, during again storing mud, substantial amounts of air can be gathered in the evacuation duct at spoil disposal motor 93 place, owing to the existence of air will make motor pump drainage lose efficacy；Existing way is to close valve at two, and the valve ending cover 97 then opening valve body 96 is exhausted, and so operation is the most inconvenient, inefficiency, is unfavorable for that what mummification operated is persistently carried out, and is unfavorable for Automated condtrol.
Utility model content
The purpose of this utility model is for problem above, it is provided that a kind of air-prevention blocking valve for mud transport, prevents air from blocking motor, it is easy to the operation of dispatch mud persistently carry out, and simple in construction is without manual operation, automatically carries out air discharge, facilitate Automated condtrol.
For realizing object above, the technical solution adopted in the utility model is: a kind of air-prevention blocking valve for mud transport, it includes valve body (96), and the valve ending cover (97) at its two ends, it is provided with escape pipe installing hole (10) on the upper valve end cap (97) of valve body (96), coordinate in it and lower escape pipe (1) is installed, and lower escape pipe (1) is connected above float cavity (2), float cavity (2) is provided above escape pipe (3), is provided with the mobilizable float (4) for blocking upper escape pipe (3) in float cavity (2).
Further, described upper escape pipe (3) is provided above union joint (5), and the connection of union joint (5) end has air-out hose (6).
Further, described union joint (5) is provided with controlled valve.
Further, described air-out hose (6) is rubber hose.
Further, described float (4) lower end is spherical structure, its upper surface trapezoidal frustum structure.
The beneficial effects of the utility model: this utility model provides a kind of air-prevention blocking valve for mud transport, prevent air from blocking motor, it is simple to the operation of dispatch mud is persistently carried out, and simple in construction is without manual operation, automatically carry out air discharge, facilitate Automated condtrol.

Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model; below in conjunction with the accompanying drawings this utility model is described in detail; the description of this part is only exemplary and explanatory, should not have any restriction effect to protection domain of the present utility model.
As shown in figs 2-4, concrete structure of the present utility model is: it includes valve body 96, and the valve ending cover 97 at its two ends, it is provided with escape pipe installing hole 10 on the upper valve end cap 97 of valve body 96, coordinate in it and lower escape pipe 1 is installed, and lower escape pipe 1 is connected above float cavity 2, float cavity 2 is provided above escape pipe 3, is provided with the mobilizable float 4 for blocking upper escape pipe 3 in float cavity 2.
Preferably, described upper escape pipe 3 is provided above union joint 5, and the connection of union joint 5 end has air-out hose 6.
Preferably, described union joint 5 is provided with controlled valve, controlled valve is set and is easy to carry out venting process in the stipulated time, simultaneously can be at float just in case carrying out emergency process in the case of losing efficacy.
Preferably, described air-out hose 6 is rubber hose.Rubber hose is easy to later maintenance, replacing.
Preferably, described float 4 lower end is spherical structure, its upper surface trapezoidal frustum structure.Use such structure first to ensure the pipeline opening of the float tight sealed upper end of energy, prevent from leaking；Ensure that float will not deflect simultaneously.
Time specifically used, as shown in Figure 4, when being filled with mud (it is mud mixture) in sewage sludge storage pond 90, it is communicated at valve body 96 by discharge pipeline 91, logical full muddy water in valve body 96, muddy water enters in float cavity 2, and the float 4 clogging upper escape pipe 3 that floats realizes seal for pipe joints, and spoil disposal motor 93 normally works and carries out pump drainage muddy water.
After the muddy water in sewage sludge storage pond 90 empties, air has entered into discharge pipeline 91 and valve body 96, the work space of spoil disposal motor 93, and owing to the gravity of float 4 is more than air, float 4 falls, so that upper escape pipe 3 is opened；And sewage sludge storage pond 90 is when again accumulating mud, the air in pipeline concentrates at valve body 96 present position, now opens and is provided with controlled valve on union joint 5, and air is by upper escape pipe 3 discharge line, so that spoil disposal motor 93 normally works.
It should be noted that, in this article, term " includes ", " comprising " or its any other variant are intended to comprising of nonexcludability, so that include that the process of a series of key element, method, article or equipment not only include those key elements, but also include other key elements being not expressly set out, or also include the key element intrinsic for this process, method, article or equipment.
Principle of the present utility model and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method of the present utility model and core concept thereof.The above is only preferred implementation of the present utility model, should be understood that, finiteness due to literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, on the premise of without departing from this utility model principle, it is also possible to make some improvement, retouch or change, it is also possible to above-mentioned technical characteristic is combined by rights；These improve retouching, change or combine, or the most improved design by utility model and technical scheme directly apply to other occasion, are regarded as protection domain of the present utility model.
