Abstract

This utility model discloses a system for diagnosing faults in the secondary circulating water pipeline of a blast furnace and for energy conservation and antifreeze protection, relating to the technical field of ironmaking equipment. This system includes a base, with a housing fixedly installed on the upper surface of the base. A partition is fixedly installed inside the housing. One side of the housing is connected to an inlet pipe, and the other side is connected to an outlet pipe. A water pump is connected to one side of the housing, and the inlet of the water pump is connected to a return pipe. A vertical pipe is fixedly installed on one side of the housing, with one side connected to one side of the housing.

Description

Technical Field

[0001] This utility model relates to the field of ironmaking equipment technology, specifically to a system for judging faults in the secondary circulating water pipeline of a blast furnace and for energy-saving and antifreeze purposes. Background Technology

[0002] In the secondary circulating water system of a blast furnace, water is pumped from the water tank, pressurized by the pump, and delivered to an evaporative air cooler or plate heat exchanger to exchange heat in the blast furnace demineralized water system. The water that has received heat is cooled by a cooling tower and returned to the water tank to continue circulating. Antifreeze systems are often used in the secondary circulating water pipeline of the blast furnace.

[0003] However, current antifreeze systems on the market cannot detect pipe leaks during use, which affects the antifreeze operation of the system and thus its ease of use. Utility Model Content

[0004] The purpose of this invention is to provide a system for diagnosing faults in the secondary circulating water pipeline of a blast furnace and for energy-saving and antifreeze protection, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a system for judging faults in the secondary circulating water pipeline of a blast furnace and for energy conservation and antifreeze, comprising a base, a shell fixedly installed on the upper surface of the base, a partition fixedly installed inside the shell, an inlet pipe connected to one side of the shell, an outlet pipe connected to the other side of the shell, a water pump connected to one side of the shell, and a return pipe connected to the inlet of the water pump. The partition, inlet pipe, and outlet pipe allow for real-time monitoring of the water level during use. The water pump and return pipe facilitate return water operation, prevent pipeline freezing during use, and improve the ease of use of the system.

[0006] A vertical pipe is fixedly installed on one side of the shell, and one side of the vertical pipe is connected to one side of the shell. A tension spring is fixedly installed on the inner bottom wall of the vertical pipe, and a floating block is fixedly installed on the top of the tension spring. When the water level inside the shell rises, the buoyancy of the water will push up the floating block, thereby changing the height of the floating block. The height of the floating block can be observed through the observation slot, which facilitates the observation of the water level inside the shell and facilitates subsequent use.

[0007] Preferably, the partition divides the shell into two cavities, and the partition has a circular hole that connects the two cavities. The circular hole facilitates the flow of water during use, thereby maintaining the connection between the two cavities on both sides of the partition.

[0008] Preferably, both the inlet pipe and the outlet pipe are set at an incline, with the inlet of the inlet pipe located at the highest end of the housing and one end of the outlet pipe located at the lowest end of the housing. The inlet and outlet pipes facilitate the passage of water during use and prevent water residue.

[0009] Preferably, mounting plates are fixedly installed on both sides of the bottom of the base. The mounting plates have mounting holes, which are elongated holes. The lower surface of the mounting plates has anti-slip texture. The mounting plates facilitate installation and positioning during use, maintaining the ease of system installation and facilitating subsequent use.

[0010] Preferably, the surface of the floating block is slidably connected to the inner wall of the vertical pipe, and an observation groove is provided on one side of the vertical pipe. The inner wall of the observation groove is inlaid with a glass plate. The observation groove and the glass plate are provided so that the height of the floating block inside the vertical pipe can be observed through the glass plate during use, thereby facilitating the observation of the water level.

[0011] Preferably, a limiting slide rod is fixedly installed on the inner bottom wall of the vertical tube. The top of the limiting slide rod passes through the floating block and extends to the top of the floating block, where it is fixedly connected to the inner top wall of the vertical tube. The limiting slide rod facilitates the limiting of the floating block during use, thereby maintaining the normal movement of the floating block during use.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This system for judging faults in the secondary circulating water pipeline of a blast furnace and for energy saving and antifreeze uses a vertical pipe. When the water level inside the shell rises, the buoyancy of the water will lift the floating block, thereby changing the height of the floating block. The height of the floating block can be observed through the observation trough, which facilitates the observation of the water level inside the shell and makes subsequent use more convenient.

[0014] (2) This system for judging faults in the secondary circulating water pipeline of blast furnace and for energy saving and antifreeze, through the setting of baffles, inlet pipes and outlet pipes, can monitor the water level in real time during use. At the same time, the setting of water pumps and return pipes facilitates the return water operation, avoids the pipeline from freezing during use, and improves the ease of use of the system.

The system incorporates a water return process to prevent pipe freezing during use, thus improving ease of use. A partition 3 divides the housing 2 into two cavities, with a circular hole connecting the two cavities. This circular hole facilitates water flow during use, maintaining communication between the two cavities. Both the inlet pipe 4 and outlet pipe 5 are angled, with the inlet of the inlet pipe 4 located at the highest point of the housing 2 and one end of the outlet pipe 5 at the lowest point. This design allows for easy water passage and prevents water residue.

A tension spring 7 is fixedly installed on the inner bottom wall of the vertical pipe 6, and a float block 8 is fixedly installed on the top of the tension spring 7. When the water level inside the shell 2 rises, the buoyancy of the water will push up the float block 8, thereby changing the height of the float block 8.

Mounting plates 9 are fixedly installed on both sides of the bottom of the base 1. The mounting plates 9 have mounting holes, which are oblong holes. The lower surface of the mounting plates 9 has anti-slip texture. The mounting plates 9 are designed to facilitate adjustment during use.
