Description

Sludge composting aeration device

Technical Field

The utility model relates to an aeration device, in particular to a sludge composting aeration device with aeration holes not easy to block.

Background

Tap water generates a large amount of muddy water in the process, the muddy water mainly comes from muddy water discharged from a sedimentation tank, backwashed muddy water discharged from a filter tank and physically backwashed muddy water discharged from a membrane tank, the muddy water accounts for about 4% -7% of the total water production amount of the whole water plant, and the muddy water contains about 0.1% -1% of solids, if the muddy water is directly discharged, not only the muddy river bed hinders navigation and flood discharge, but also water resources are wasted and the environment is polluted.

The sludge water is mechanically dehydrated or naturally dried into sludge. The main components of tap water sludge are sediment, impurities, plankton, algae debris, various flocculant components added to water, and the like in raw water. The recycling of the waterworks sludge brings remarkable benefits from the aspects of economic factors, social factors and environmental factors.

For example, the sludge can be subjected to aerobic composting to remove harmful components in the sludge, so that the sludge is recycled, and the waste is turned into wealth. However, at present, a simple porous pipeline is mostly adopted in the composting facility to supply oxygen for the aeration of the pile body, and the phenomenon that the aeration holes are blocked by percolate of the pile body exists in the aeration process. These all cause uneven distribution of the gas, resulting in local anaerobic conditions in the stack. The activity of microorganisms and the conversion of substances under anaerobic conditions can form substances which are unfavorable for the composting degree, thereby influencing the treatment effect and the treatment efficiency of the sludge.

Detailed Description

The following describes specific embodiments of the present utility model in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the utility model, are not intended to limit the utility model.

In the following description, the terms "outer" and "inner" refer to terms such as directions in which parts of the aeration device are normally positioned, for example, a part through which the gas passes is an interior, and a part opposite to the interior is an exterior. It is used merely for convenience in describing the utility model and to simplify the description and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operate in a particular orientation, and thus should not be construed as limiting the utility model.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted" and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; either directly or indirectly via an intermediate medium, or in communication with each other or in interaction with each other. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

As shown in fig. 1-3, the sludge composting and aerating apparatus of the present utility model comprises an air storage tank 2, a main pipe 3 connected with the air storage tank 2, at least one main pipe 6 connected with the main pipe 3, and a plurality of branch pipes 8 connected with the main pipe 6, wherein aeration holes 11 are formed on the branch pipes 8, rubber sleeves 12 are further sleeved on the branch pipes 8, and notches 13 corresponding to and overlapping with the aeration holes 11 are formed on the rubber sleeves 12.

When the technical scheme is used, gas in the gas storage tank 2 sequentially passes through the main pipe 3, the main pipe 6 and the branch pipe 8 and is discharged from the aeration holes 11, and the gas in the aeration holes 11 generates pressure on the cut 13 of the rubber sleeve 12 corresponding to the aeration holes 11, so that the cut 13 is opened, and the gas is aerated outside the branch pipe 8; when aeration is not needed, no aeration air pressure exists in the notch 13, so that the notch 13 is closed, and further the situation that sludge enters the aeration holes 11 to block the aeration holes 11 is avoided. I.e. the rubber sleeve 12 corresponds to a one-way valve, the slit 13 being opened only when aerated and closed when not aerated.

The slit 13 may be a single slit or a cross slit, and the length of the slit 13 is greater than or equal to the aperture of the aeration holes 11 in order to ensure sufficient aeration.

When the length of the notch 13 is greater than the aperture of the aeration hole 11, the difference between the length of the notch 13 and the aperture of the aeration hole 11 is less than or equal to 5mm, so that the notch 13 is prevented from being too large to cause the material on the notch to generate pressure on the notch, so that the notch is inwards sunk, and the aeration hole 11 is blocked.

In the above technical solution, the branch pipe 8 may be provided with one or more rubber sleeves 12. When one branch pipe 8 is provided with a rubber sleeve 12, a plurality of notches 13 are arranged on the branch pipe to correspond to the aeration holes 11 one by one; when a plurality of rubber sleeves 12 are arranged on one branch pipe 8, one or a plurality of cuts 13 corresponding to the aeration holes 11 one by one are arranged on each rubber sleeve 12.

In addition, in order to prevent the rubber boot 12 from moving on the branch pipe 8, a limiting protrusion 15 for limiting the rubber boot 12 is provided on the branch pipe 8. Specifically, one rubber boot 12 corresponds to 2 limit protrusions 15, and the interval between the two limit protrusions 15 is equal to the width of the rubber boot 12.

The main pipe 6 and the branch pipe 8 can be fixedly connected by welding, etc., but for convenient installation and disassembly, the main pipe 6 and the branch pipe 8 can also be detachably connected by a four-way joint 7.

In order to increase the air pressure in the branch pipe 8 for facilitating aeration, the diameter of the branch pipe 8 is smaller than that of the main pipe 6, in this case, the four-way joint 7 may be an equal-diameter four-way joint or a reducing four-way joint, and when the four-way joint is an equal-diameter four-way joint, the branch pipe 8 is connected with the equal-diameter four-way joint through a big head 9.

The main pipe 6 and the branch pipe 8 can be straight pipes or non-straight pipes with closed top ends, and when the main pipe is a straight pipe, the end, far away from the main pipe 3, of the main pipe 6 is blocked by a main pipe plug 14, and the end, far away from the main pipe 6, of the branch pipe 8 is blocked by a branch pipe plug 10.

On the basis of the technical scheme, one end of the main pipe 6, which is close to the main pipe 3, is provided with a valve 5. The valve 5 may be a manual valve or a solenoid valve to vent or not vent the main 6 as desired.

In addition, an air compressor 1 is connected to the air tank 2 to ensure that sufficient air is always present in the air tank 2.
