Abstract

A backwater heat insulation cover comprises a cover body, a backwater pipe, a filter sleeve and a sponge core. The cover body is provided with at least one air dispersing hole. And the backflow water vapor flowing out of the water return pipe is sprayed on the sponge core. The sponge core absorbs the water in the backflow water vapor flowing out of the backflow pipe and prevents part of the steam in the backflow water vapor from passing through the sponge core so that the steam is discharged from the air diffusion holes. The backwater heat insulation cover is provided with a filter sleeve and a sponge core. When the backflow water vapor returns from the water return pipe, the backflow water vapor is sprayed on the sponge core, the sponge core absorbs the backflow water, and when the backflow water is enough, the backflow water vapor flows into the cold water bin. Because the sponge core after absorbing water makes high temperature steam can not pass through to make the steam in the backward flow aquatic filtered out, thereby can avoid this high temperature hot steam to further heat the water in the cold water storehouse.

Description

Backwater heat insulation cover

Technical Field

The utility model relates to the field of pipeline backwater devices, in particular to a backwater heat-insulating cover.

Background

There is the return water pipe in some hot water circulating system, and the return water pipe can be with in the unnecessary hot water backward flow to the cold water storehouse of flowing out in following the hot water storehouse to guarantee that the water resource is not extravagant. However, the water returned to the cold water tank is hot and carries steam. Therefore, the steam carried in the hot water can emit a large amount of heat during condensation, and the temperature rise of the cold water in the cold water bin is accelerated. However, the high-pressure water pump in the circulation system is not suitable for working in high-temperature environment, and the service life of the high-pressure water pump is greatly shortened when the high-pressure water pump is located in the high-temperature environment for a long time. Therefore, there is a need for a device for removing steam from the returned hot water.

Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the utility model is not intended to limit the scope of the utility model.

As shown in fig. 1 to 4, which are schematic structural views of a backwater heat insulation cover provided by the present invention. The backwater heat insulation cover comprises a cover body 10, a backwater pipe 20 inserted at the top of the cover body 10, a filter sleeve 30 arranged at the bottom of the cover body 10, and a sponge core 40 filled between the filter sleeve 30 and the cover body 10. It is conceivable to include some functional modules, such as a cold water bin sleeved on the bottom of the cover 10, a water pump assembly for controlling the flow of the return water, etc., which are well known to those skilled in the art and will not be described herein.

At least one air dispersing hole 11 is formed at the top of the cover body 10. In this embodiment, the number of the air diffusing holes 11 is six, and the air diffusing holes are distributed in a central symmetry manner with the insertion position of the water return pipe 20 as a center. The air diffusing hole 11 is positioned right above the filter sleeve 30. The bottom of the cover 10 is provided with a retainer ring 12. The retainer ring 12 is spaced from the side of the cap body 10 so that an annular groove 13 is formed between the retainer ring 12 and the side of the cap body 10. The opening edge of the cold water bin is clamped in the annular groove 13, so that the leakage of liquid in the cold water bin is reduced. The retainer ring 12 may be made of rubber, and the width of the annular groove 13 may be equal to or slightly less than the thickness of the opening edge of the cold water storage bin, so that the sealing performance can be enhanced.

The water return pipe 20 is disposed at a top center position of the cover body 10. The outside cover of the end of return pipe 20 is equipped with a return pipe bush 21. The return pipe bushing 21 is inserted into the center of the cover 10. The end of the return pipe 20 is flush with the end of the return pipe liner 21, so that the return pipe 20 does not touch the end of the return pipe 20 and damage the return pipe 20 during installation and use.

The filter sleeve 30 is disposed at the bottom of the cover 10, and the filter sleeve 30 is located at the bottom of the air-diffusing hole 11 and the water return pipe 20. An annular mounting piece 31 is arranged around the opening of the filter sleeve 30, and a fixing bolt is inserted between the annular mounting piece 31 and the cover body 10, so that the filter sleeve 30 is fixedly mounted at the bottom of the cover body 10. The material of the filter sleeve 30 can be selected from aluminum alloy, and the corrosion resistance is strong. The bottom and the side of the filter sleeve 30 are provided with small holes at intervals, so that the backflow water can pass through the filter sleeve conveniently.

The sponge core 40 is filled in the filter sleeve, and the air is difficult to pass through after the sponge core 40 absorbs water, so after the backflow water flows into the filter sleeve 30, the water vapor in the backflow water is blocked by the sponge core 40 and cannot enter the cold water bin. The cross-sectional area of the sponge core 40 is the same as that of the inner cavity of the filter sleeve 30, so that water vapor is prevented from leaking into the cold water bin from a gap between the sponge core 40 and the filter sleeve 30. In one embodiment, the sponge core 40 is provided with a groove 41 at the top for temporarily storing water vapor. The groove 41 is trumpet-shaped, and the position of the groove 41 corresponds to the position of the air diffusion hole 11, so that hot air in the groove 41 can be diffused quickly. In another embodiment, the thickness of the sponge core 40 is smaller than the thickness of the inner cavity of the filter casing 30, so that when the sponge core 40 is packed in the filter casing 30, a steam storage space 42 is formed between the sponge core 40 and the cover 10. The vapor storage space 42 can store part of the vapor after the vapor in the return water is filtered out, and then release the vapor. These two kinds of embodiments all are provided with a space that can deposit partial steam, avoid filtering out a large amount of steam in the twinkling of an eye after, a large amount of steam make local other too big lead to the device impaired. In actual use, a suitable steam storage mode is selected according to needs, and details are not repeated herein. The filtered water vapor is discharged through the air diffusing holes 11.

Compared with the prior art, the backwater heat insulation cover provided by the utility model is provided with a filter sleeve 30 and a sponge core 40 filled in the filter sleeve 30. When the backflow steam is returned from the water return pipe 20, the backflow steam is sprayed on the sponge core 40, the sponge core 40 absorbs the backflow water, and when the backflow water is enough, the backflow water flows into the cold water bin, meanwhile, high-temperature hot air cannot pass through the sponge core 40 after water absorption, so that the steam in the backflow water is filtered out, and the filtered steam can only be emitted through the air emission holes 11, so that the situation that the water in the cold water bin is further heated by the high-temperature hot steam can be avoided, and the service life of the water pump is shortened due to the fact that the water pump pumps the high-temperature hot water can be avoided.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
