Abstract
Description
Technical Field
[0001] The utility model relates to a blast furnace mud cannon mud quantity control technology, in particular to a blast furnace mud cannon mud quantity measuring device. Background Art
[0002] The blast furnace mud cannon is an important equipment in the furnace front position. Its main work content is to drive the cannon mud into the iron mouth to seal the iron mouth. The amount of mud will directly determine the depth of the iron mouth of the next furnace, affect the iron mouth qualification rate, and thus affect the iron tapping conditions. If the amount of mud is small, the iron mouth is shallow, the opening is difficult and time is long, which affects the smooth operation of the furnace; if the amount of mud is large, the iron mouth is deep and damp, it is easy to release "rocket launchers", smoke and dust are discharged, and environmental accidents occur. At present, the on-site operation can only estimate the amount of mud based on experience. The deviation of the mud amount in the upper and lower furnaces is large, and it cannot be accurately controlled, which seriously affects the normal production of the blast furnace. Summary of the invention
[0003] In view of the problems existing in the prior art, the utility model proposes a blast furnace mud gun mud measuring device, which is provided with an observation hole on the gun body and a mark on the piston rod for expressing the extension amount of the piston. In daily operation, it is convenient to observe the amount of mud, and compared with empirical evaluation, the mud amount and the iron mouth depth can be controlled relatively accurately, and the iron mouth management and operation can be optimized, so as to reduce the consumption of tons of iron and save costs.
[0004] The technical solution adopted by the utility model is: a blast furnace mud gun mud measuring device, comprising a gun body, a mud gun nozzle is arranged at the front end of the gun body, the gun body has a cavity, the piston of the hydraulic oil cylinder is axially slidably installed in the cavity, the piston is fixed to the head of the piston rod, an observation hole is opened on the gun body corresponding to the movement path of the piston rod, and a plurality of marks expressing the extension amount of the piston rod are arranged on the piston rod.
[0005] Based on the above solution, preferably, the observation hole is a rectangular hole.
[0006] Based on the above solution, preferably, the rectangular hole is 24 cm long and 15 cm wide.
[0007] On the basis of the above scheme, as a preferred embodiment, the marks are holes drilled on the piston rod using a drill bit, there are 12 marks in total, the number of holes at each mark is different, and the interval between two adjacent marks is 5 cm.
[0008] Based on the above solution, preferably, red, yellow or white gel is poured into the hole.
[0009] Based on the above solution, preferably, the mark is a label pasted on the piston rod.
[0010] Based on the above solution, as a preferred embodiment, the mark is a scale engraved on the surface of the piston rod, and a yellow layer is coated on the scale.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] By opening an observation hole on the gun body and setting a mark on the piston rod to express the amount of piston extension, it is easy to observe the amount of mud pumped in daily operation. Compared with empirical evaluation, the amount of mud and the iron mouth depth can be controlled relatively accurately, and the iron mouth management and operation can be optimized, the consumption of tons of iron can be reduced, and costs can be saved. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0014] The present invention will be further described below by way of embodiments, but the scope of the present invention is not limited thereto.
[0015] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0016] like Figure 1 As shown, a blast furnace mud gun mud measuring device comprises a gun body 1, a mud gun nozzle 2 is arranged at the front end of the gun body, the gun body has a cavity 3, a piston 4 of a hydraulic cylinder is axially slidably installed in the cavity, the piston is fixed to the head of a piston rod 5, an observation hole 6 is opened on the gun body corresponding to the movement path of the piston rod, and a plurality of marks 7 expressing the extension amount of the piston rod are arranged on the piston rod.
[0017] By opening an observation hole on the gun body and setting a mark on the piston rod to express the amount of piston extension, it is easy to observe the amount of mud pumped in daily operation. Compared with empirical evaluation, the amount of mud and the iron mouth depth can be controlled relatively accurately, and the iron mouth management and operation can be optimized, the consumption of tons of iron can be reduced, and costs can be saved.
[0018] The observation hole is a rectangular hole or a hole of any other shape.
[0019] The rectangular hole is 24cm long and 15cm wide.
[0020] For tags, you can choose:
[0021] The marks are holes drilled on the piston rod using a drill. There are 12 marks in total. The number of holes at each mark is different, and the interval between two adjacent marks is 5 cm. The marking of the drilled holes does not require additional parts, is simple and easy to operate. To make the holes easier to observe, red, yellow or white gel is poured into the holes, preferably yellow.
[0022] The mark can also be a label attached to the piston rod. The label has low cost but low service life.
[0023] The mark can also be a scale engraved on the surface of the piston rod, with a yellow coating on the scale, which requires secondary processing of the piston rod, which is costly.
[0024] Considering the cost, life and accuracy, drilling is more convenient.
