Description

Mud deposition preventing device at bottom of gas-tight U-shaped elbow

Technical Field

The utility model relates to a gaseous airtight U-shaped return bend bottom prevents mud deposition apparatus, it belongs to the airtight mud technical field that prevents of retort.

Background

Generally, the overflow tank and the reaction tank need to be connected through a pipeline in use, the tank bodies of the conventional factory are mostly connected through a straight pipe or an inclined pipe, the straight pipe connection does not play any role in preventing gas from communicating and gas from leaking, and although the inclined pipe can play a role in sealing, the lower end of the inclined pipe is easy to block and scale because solids are generated in reaction. The existing tank bodies are connected by adopting the elbow, the problem of water sealing is solved, but the elbow is easy to have the phenomenon of mud deposition at the bottom along with the increase of time, and the methods for cleaning the elbow are generally three, one is to pour a scale remover into the elbow for cleaning, and use the scale remover for cleaning, and the scale remover can directly wash away the scale remover due to the delivery of fluid in a U-shaped elbow, so that the scale remover can not play a role. If the scale remover is added after the interception, a large amount of time is consumed for waiting for the scale remover to act, and the fluid conveying of the system is influenced; one is to stir and wash by using a dredging spiral stirring and a water pipe. Along with stirring, the deposited mud can be taken away by the water flow quickly, but the method can only simply treat part of the deposited mud and cannot influence the hard scaling phenomenon; and the other method is that four elbows of the formed elbow are connected by flanges, once blockage and scaling occur, the elbow can be detached and cleaned, and although the method can completely clean and remove the scaling, the system can also be subjected to a condition of stopping running for a long time. If the pipe diameter of the U-shaped bent pipe is too large, such as the U-shaped bent pipe made of 304 stainless steel materials of DN200, the cost of the flange involved by the U-shaped bent pipe is not small, and the weight, the difficulty of disassembly and assembly of the U-shaped bent pipe can be increased, and the labor intensity is increased.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the not enough of existence among the above-mentioned prior art, provide a gaseous airtight U-shaped return bend bottom prevents mud deposition apparatus.

The utility model provides an above-mentioned technical problem's technical scheme as follows:

the utility model provides a gaseous airtight U-shaped return bend bottom prevents mud deposition apparatus, includes overflow jar and retort, be equipped with the U-shaped return bend between overflow jar and the retort, the upside of U-shaped return bend is equipped with the mediation mouth, the lower extreme of U-shaped return bend is equipped with down dredges the opening, the left side of dredging the opening down is connected with the clear water pipe.

Preferably, the number of the upper dredging openings is two, and the two dredging openings are respectively arranged on two sides of the upper end of the U-shaped bent pipe.

Preferably, the upper dredging opening and the lower dredging opening are communicated with the inside of the U-shaped elbow.

Preferably, the outer end parts of the upper dredging opening and the lower dredging opening are respectively provided with a flange cover.

Preferably, the U-shaped bent pipe is formed by welding four bent pipes and two straight pipes.

Preferably, a valve is further arranged on the U-shaped elbow.

Compared with the prior art, the beneficial effects of the utility model are that: adopt the U-shaped return bend, the overflow pipe can not soaked in the reaction liquid, the solid that has prevented to produce in the retort arouses blockking up and scale deposit, and the U-shaped return bend can play the water seal effect, can effectively prevent the gas refluence that produces, prevent gaseous diffusion outward, the gaseous easier collection of production, dredge opening and clear water pipe on the U-shaped return bend, can be with its inside deposit mud and scale deposit clean up, and the space of dredging opening and providing down can deposit a certain amount of deposit mud, the ability of crossing water of U-shaped return bend also can be guaranteed even when having the deposit mud in its space range has been guaranteed.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

The utility model provides a gaseous airtight U-shaped return bend bottom prevents mud deposition apparatus, includes overflow tank 1 and retort 2, be equipped with U-shaped return bend 3 between overflow tank 1 and the retort 2, the upside of U-shaped return bend 3 is equipped with mediation mouth 4, the lower extreme of U-shaped return bend 3 is equipped with down dredges opening 5, the left side of dredging opening 5 down is connected with clear water pipe 6.

The number of the upper dredging openings 4 is two, and the two dredging openings are respectively arranged at two sides of the upper end of the U-shaped bent pipe 3.

The upper dredging port 4 and the lower dredging port 5 are communicated with the inside of the U-shaped bent pipe 3.

And the outer end parts of the upper dredging opening 4 and the lower dredging opening 5 are respectively provided with a flange cover 7.

The working principle is as follows:

overflow through U-shaped return bend 3 after overflow jar 1 reaches certain liquid level in to retort 2, add the medicine in retort 2 and react, the reaction produces gaseous water of detaining in U-shaped return bend 3 through the relict, and the gaseous overflow jar 1 that returns that effectively prevents to produce effectively prevents gaseous diffusion outward, and the gaseous collection that also is easier of production. When long-term work U-shaped return bend 3 is inside when having scale deposit and deposit mud, close the valve, can open two upper portions and dredge 7 of mouthful 4 flange cover on 3 inner walls of U-shaped return bend to open the flange cover 7 on dredging the mouth 5 down, and utilize clean water pipe 6 to take away the deposit mud of bottom, the back of finishing the clearance, install respectively flange cover 7 on dredging mouthful 4 and dredging the mouth 5 down, and open the valve and guarantee to overflow. Because the whole cleaning process is very short, the uninterrupted overflowing of the U-shaped bent pipe 3 is ensured to the maximum extent, and because a part of deposited mud can be deposited at the bottom of the lower dredging port 5, the overflowing capacity between the tank bodies can be ensured even when a part of deposited mud exists.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
