Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of furnace water circulation pipe, especially relates to a circulating pipe of furnace water circulating pump. BACKGROUND

[0002] The circulating pipe of the furnace water circulating pump is an important component for connecting the circulating pump with other parts in the boiler system to realize the circulation of furnace water, and is responsible for connecting the circulating pump with other parts (such as a water storage tank, a boiler body, etc.) in the boiler system to form a complete fluid circulation loop, so as to ensure that the furnace water can circulate according to the set path and flow rate.

[0003] However, during the use of the circulating pipe, it is found that bicarbonate and other substances in water will increase with evaporation concentration to form scale attached to the pipe wall, thereby reducing the heat transfer efficiency and even causing blockage and under-deposit corrosion.

[0004] To solve the above problems, the circulating pipe of the furnace water circulating pump is provided in the application. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a circulating pipe of furnace water circulating pump, which solves the problems in the background art.

[0006] To solve the above technical problems, the utility model is implemented by the following technical scheme:

[0007] The utility model is a circulating pipe of furnace water circulating pump, which comprises a circulating pipe, a limiting frame distributed at the water inlet end and the water outlet end of the circulating pipe, a first inner ring frame located inside the limiting frame at the water inlet end of the circulating pipe, an inner guide plate arranged in the first inner ring frame for guiding the input circulating water to form spiral water flow, thereby scouring the inner wall of the circulating pipe to make the adsorbed particles automatically fall off, a second inner ring frame located inside the circulating pipe at the water outlet end of the circulating pipe, an inner flat filter plate and a conical filter plate arranged in the second inner ring frame, wherein the conical filter plate is adjacent to the outlet and is used for separating the particles in the circulating water, the conical filter plate is also used for guiding the particles to be accommodated between the ring filter plate and the inner wall of the second inner ring frame, and the ring filter plate is located in the adjacent outer ring region inside the second inner ring frame and is provided with an opening adjacent to one end of the conical filter plate.

[0008] Further, the two ends of the circulating pipe are provided with sealing pads for sealing the side ring at the end of the limiting frame, and one end of the limiting frame adjacent to the pipe opening is an inclined guide structure.

[0009] Further, the other end of the limiting frame is provided with a positioning ring frame, and convex rings are arranged between the limiting frame and the stop block and are connected in a spiral manner.

[0010] Further, the first inner ring frame is provided with a ball through a positioning groove arranged on the outer side of the first inner ring frame, so as to reduce the rotational resistance of the first inner ring frame.

[0011] Furthermore, the outer side of the second inner ring frame has the same structure as the outer side of the first inner ring frame, which is used to cause particles to move towards the outer ring of the cone filter plate during rotation.

[0012] Furthermore, the inner side of the positioning ring frame is provided with a protruding stop, which, together with the protruding structure on the inner side of the limiting frame, forms an annular groove for installing the first inner ring frame and the second inner ring frame.

[0013] Furthermore, the combination of spiral water flow and the separation effect of cone filter plates is used to continuously purify the circulating water inside the circulation pipe and reduce the particle content in the water.

[0014] This utility model has the following beneficial effects:

[0015] This invention, by adding a first inner ring frame, enables the circulating water to form a spiral flow state when entering the circulating pipe, thereby flushing the inner wall of the circulating pipe and causing the adsorbed particles to fall off, preventing the formation of dirt on the inner wall of the circulating pipe, ensuring stable water flow, preventing under-deposit corrosion, and facilitating long-term circulating water supply of the pipe.

[0016] This invention, by adding a second inner ring frame, allows detached particles to be guided by the cone filter plate to form a storage between the ring filter plate and the second inner ring frame. This ensures a stable circulating water flow while cleaning up particulate impurities in the water in real time, achieving continuous purification of the circulating water. As a result, the number of particles in the water gradually decreases, thereby protecting the circulation pipe and extending its service life.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
