Technical Field

[0001] The utility model relates to the technical field of measuring devices, and more specifically, to a blast furnace tuyere copper sleeve installation space measuring device. Background Art

[0002] At present, the replacement and installation of the copper sleeve of the blast furnace tuyere is usually done by manually cleaning the slag and charge in the installation space. When the installation space of the copper sleeve is cleaned to a certain extent, the copper sleeve spare parts to be replaced are then driven in and installed by external force. If the installation space is not cleaned in place, the copper sleeve needs to be pulled out again, and the slag and charge in the installation space are cleaned again. After the copper sleeve spare parts are driven in, the sealing surface fits tightly without gaps, and the installation is completed. Since the copper sleeve of the tuyere is a conical structure and relatively large in size, it is impossible to measure whether the installation space meets the installation requirements by two common methods. Excessive cleaning of the installation space can easily reduce the operating efficiency and cause the collapse of the charge.

[0003] Therefore, it is urgent to design a blast furnace tuyere copper sleeve installation space measurement device to solve the above-mentioned problems. Utility Model Content

[0006] As a further improvement, the measuring plate is a 2 mm stainless steel plate, and the frame is made of stainless steel.

[0007] Furthermore, the support plates corresponding to the first support ring, the second support ring and the third support ring are connected via a connecting pipe.

[0008] Furthermore, one end of the connecting pipe movably passes through the first support ring, the supporting disk corresponding to the second support ring and is threadedly connected to the supporting disk corresponding to the third support ring, and a locking nut is threadedly connected to the connecting pipe on one side of the first support ring.

[0021] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0022] See also Figure 1-4 The utility model discloses a device for measuring the installation space of a blast furnace tuyere copper sleeve, comprising a frame 1 and a measuring plate 2, wherein the frame 1 is in a cone shape and is designed according to the size of the tuyere copper sleeve spare parts to be replaced. The measuring plate 2 is coated on the outer wall of the frame 1 to form a cone with openings at both ends. The frame 1 serves to improve the structural strength of the measuring device, and the size of the measuring plate 2 is consistent with the size of the tuyere copper sleeve spare parts to be replaced, so that when the entire measuring device is inserted into the installation space of the blast furnace, it can just fit the sealing surface. Specifically, the skeleton 1 includes a first support ring 11, a second support ring 12 and a third support ring 13 with diameters decreasing successively. The inner wall of the measuring plate 2 is connected to the outer walls of the first support ring 11, the second support ring 12 and the third support ring 13 at the same time. The first support ring 11, the second support ring 12 and the third support ring 13 are each provided with a support plate 14. The support plate 14 is connected to the inner walls of the first support ring 11, the second support ring 12 and the third support ring 13 through a plurality of evenly distributed support rods 15 to form an effective support for the measuring plate 2. Handles 16 are provided on both sides of the first support ring 11 to facilitate taking the measuring device.

[0023] The measuring device of the utility model is constructed by covering the measuring plate 2 on the outer wall of a conical skeleton 1 to have a size consistent with the size of the spare part of the tuyere copper sleeve to be replaced. When replacing the tuyere copper sleeve, the measuring device is placed in the installation space corresponding to the blast furnace. If the measuring device fits tightly with the sealing surface without a gap, the measuring device can be taken out and the tuyere copper sleeve can be inserted to ensure that the tuyere copper sleeve is installed successfully at one time. If there is a gap between the measuring device and the sealing surface, the measuring device needs to be taken out and continued to be cleaned until the installation space is measured to be qualified before installing the tuyere copper sleeve. This can measure whether the installation space of the tuyere sleeve is qualified, ensure that the tuyere copper sleeve is installed successfully at one time, improve working efficiency, and reduce labor intensity.

[0024] Preferably, the measuring plate 2 is a 2 mm stainless steel plate, and the frame 1 is made of stainless steel. Stainless steel is not only not easily corroded and rusted, but also has a relatively smooth surface, so that the measuring device can be well inserted into the installation space corresponding to the blast furnace.

[0025] Preferably, the support disks 14 corresponding to the first support ring 11, the second support ring 12, and the third support ring 13 are connected by a connecting pipe 17, so as to improve the structural strength of the entire skeleton 1 and facilitate the manufacture of the measuring device. Further, one end of the connecting pipe 17 movably penetrates the support disks 14 corresponding to the first support ring 11 and the second support ring 12 and is threadedly connected to the support disk 14 corresponding to the third support ring 13. A locking nut 18 is threadedly connected to the connecting pipe 17 on one side of the first support ring 11. The connecting pipe 17 is a disassembly and installation method, which is very convenient for disassembly and maintenance. Further, the connecting pipe 17 is a pipe with openings at both ends, the third support ring 13 is a hollow ring pipe, the support disk 14 corresponding to the third support ring 13 is a shell with a hollow structure, and the support rod 15 corresponding to the third support ring 13 is a hollow tube body. The connecting pipe 17 is connected to the support disk 14, the support rod 15, and the third support ring 13 corresponding to the third support ring 13 in sequence to form a gas channel, and a plurality of vents 19 are provided on the side of the third support ring 13 away from the second support ring 12.

[0026] The measuring device of this embodiment forms a gas channel by sequentially connecting the connecting pipe 17 with the support plate 14, the support rod 15, and the third support ring 13 corresponding to the third support ring 13. In actual operation, an air pump can be connected through the connecting pipe 17, and the high-pressure gas pumped out by the air pump can be sprayed through the vent hole of the third support ring to blow and clean the installation space corresponding to the blast furnace, thereby achieving cleaning while measuring, and further improving the operation efficiency. In other embodiments, the connecting pipe 17 can also be connected to a vacuum cleaner, and the impurities in the installation space corresponding to the blast furnace can be cleaned by suction, so as to prevent the impurities from falling into the blast furnace.

[0027] Preferably, multiple air holes 19 are evenly distributed along the circumference of the third support ring 13, and the axial line of each air hole 19 is inclined at 45° along the radial direction of the third support ring 13, and the axial line of each air hole 19 is inclined at 45° along the circumferential direction of the third support ring 13, so that the air flow ejected from the air holes 19 is directed toward the inner wall of the installation space corresponding to the blast furnace and forms a vortex, which can effectively improve the cleaning effect.

[0028] Preferably, the first support ring 11, the second support ring 12, the third support ring 13 and the measuring plate 2 are fixed by welding or gluing. The welding fixation method can effectively improve the structural strength of the skeleton 1, while the gluing method can make the measuring plate 2 removable relative to the skeleton 1, and maintenance is more convenient.

[0029] The above is only a preferred embodiment of the present invention. 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 present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
