Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blast furnace gas dust removal equipment, and more specifically, to a device for processing blast furnace gravity dust removal and ash discharge blockage. Background Art
[0002] The blast furnace gravity dust collector is one of the important components of the blast furnace gas purification system. The blast furnace (A) gas is pressurized by the blower and enters the upper part of the dust collector (B). Its working principle is based on the principle of gravity separation, and the blast furnace (A) gas is separated from the gas by gravity. The separated gas is discharged to the gas purification station through the raw gas pipeline (D), and the particulate matter falls on the bottom of the dust collector (B). When the dust collector (B) discharges ash through the ash discharge pipe (C), due to the spray material blocks falling on the inner wall of the dust collector (B) and the high moisture content of the gas, the particulate matter (gas ash) is easy to form blocks and cause blockage. When the dust collector (B) is unable to discharge ash due to blockage, the gas ash accumulates too much in the dust collector, which is easy to cause the blast furnace (A) to shut down. In serious cases, it is easy to cause safety accidents. Utility Model Content
[0003] The technical problem to be solved by the utility model is aimed at the above-mentioned deficiencies in the prior art. The purpose of the utility model is to provide a device for quickly clearing blockage of blast furnace gravity dust removal and ash discharge when blockage occurs in the dust collector.

[0005] As a further improvement, the anti-blocking mechanism includes a clearing pipe and a control valve. The control valve is provided in the middle of the clearing pipe, and the clearing pipe is arranged above the ash discharge valve in the middle of the ash discharge pipe.
[0006] Furthermore, the number of ash discharge pipes is two.
[0007] Furthermore, the anti-blocking mechanism includes a clearing pipe, a control valve, and a steel rod. The clearing pipe is arranged above the ash discharge valve in the middle of the ash discharge pipe. A through hole is arranged on the upper side of the clearing pipe. A steel rod is arranged inside the clearing pipe. A handle is arranged above the middle of the steel rod, and the handle passes through the through hole. A stop block is arranged at one end of the steel rod located on the outside of the clearing pipe, and a mace head is arranged at the other end of the steel rod.

[0024] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.
[0025] Embodiment 1
[0026] See also Figure 2-3A device for treating blockage of blast furnace gravity dust removal and ash discharge, comprising a gravity dust collector 11, a ash hopper 12 is provided at the lower end of the gravity dust collector 11, an ash discharge pipe 1 is provided at the bottom of the ash hopper 12, an ash discharge valve 10 is provided in the middle of the ash discharge pipe 1, and an anti-blockage mechanism is provided on one side of the ash discharge pipe 1.
[0027] The anti-clogging mechanism comprises a clearing pipe 2 and a control valve 3 . The control valve 3 is provided in the middle of the clearing pipe 2 . The clearing pipe 2 is provided above the ash discharge valve 10 in the middle of the ash discharge pipe 1 .
[0028] Preferably, the direction of the clearing pipe 2 is arranged obliquely downward.
[0029] The number of ash discharge pipes 1 is two.
[0030] The material of the cleaning pipe 2 is DN50 galvanized material.
[0031] When the blast furnace is blocked by gas ash discharge, open the control valve 3 and use a steel chisel to poke it inside to quickly and effectively clear the blockage.
[0032] Embodiment 2
[0033] See also Figure 4-5 A device for treating blockage of blast furnace gravity dust removal and ash discharge, comprising a gravity dust collector 11, a ash hopper 12 is provided at the lower end of the gravity dust collector 11, an ash discharge pipe 1 is provided at the bottom of the ash hopper 12, an ash discharge valve 10 is provided in the middle of the ash discharge pipe 1, and an anti-blockage mechanism is provided on one side of the ash discharge pipe 1.
[0034] The number of ash discharge pipes 1 is two.
[0035] The material of the cleaning pipe 2 is DN50 galvanized material.
[0036] The anti-clogging mechanism includes a cleaning pipe 2, a control valve 3, and a steel rod 4. The cleaning pipe 2 is arranged above the ash discharge valve 10 in the middle of the ash discharge pipe 1. A through hole 13 is arranged on the upper side of the cleaning pipe 2. A steel rod 4 is arranged inside the cleaning pipe 2. A handle 5 is arranged above the middle of the steel rod 4. The handle 5 passes through the through hole 13. A stop block 7 with a limiting function is arranged at one end of the steel rod 4 located on the outside of the cleaning pipe 2, and a mace head 6 is arranged at the other end of the steel rod 4.
[0037] When a blockage occurs, the blocked block of gas ash can be cleared by manually holding the handle and pushing the steel rod 4 up and down. There is no need to use another steel rod or steel chisel to operate each time, which reduces the steps of manual operation and improves the efficiency of clearing.
[0038] The spherical diameter of the mace head 6 matches the inner wall of the clearing pipe 2 .
[0039] A second ash discharge pipe 14 is provided at one end of the cleaning pipe 2 close to the ash discharge pipe 1.

[0041] The sensor 8 is electrically connected to the controller. When the sensor 8 senses that the blockage has reached a certain height, it sends out an electrical signal, causing the controller to issue a reminder. The person can hold the handle 5 and control the steel rod 4 to break the blocked block gas ash into powder ash, which can then be automatically discharged from the ash discharge pipe 1 and the second ash discharge pipe 14.
[0042] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the utility model, which will not affect the effect of the implementation of the utility model and the practicality of the patent.
