TECHNICAL FIELD
[0001] The present application relates to the field of cloth chute manufacturing, in particular to a cloth chute lining plate replaceable mounting structure. BACKGROUND
[0002] In the complex and critical process system of blast furnace ironmaking, the cloth chute plays a crucial role. Its working principle is based on the rotating device installed on the top of the blast furnace, which drives the cloth chute to realize flexible movement with multiple angles and all directions. When the furnace charge successfully enters the cloth chute from the top, the chute will uniformly spread the furnace charge in various areas inside the blast furnace according to the pre-set accurate program with different tilting angles and rotation speeds. In this way, the permeability of the blast furnace interior is guaranteed, thereby creating stable and efficient ideal conditions for the reduction reaction of iron ore. In this process, most of the furnace charge will be concentrated in the heavy impact part of the chute under the combined action of gravity and chute movement.
[0003] In terms of existing technology, to improve the wear resistance of the heavy impact part, a common method is to weld a thickened lining plate to the bottom wall of the cloth chute. However, this welding method has many drawbacks. Since the thickened lining plate is fixed by welding with the cloth chute, once the thickened lining plate is severely damaged due to long-term bearing of the strong impact and wear of the furnace charge, it cannot be replaced individually. This not only has a high probability of causing the entire cloth chute to be scrapped due to local wear, significantly increasing production costs, but also makes the operation process of replacing the entire cloth chute extremely tedious, time-consuming and labor-intensive, seriously affecting the normal production efficiency of the blast furnace.
[0004] Therefore, it is particularly urgent to develop a new technical solution to solve the replaceable problem of the wear-resistant part of the heavy impact part of the cloth chute. CONTENT OF THE INVENTION
[0005] In order to overcome the above problems, the present application provides a cloth chute lining plate replaceable mounting structure.
[0006] The cloth chute lining plate replaceable mounting structure provided by the present application adopts the following technical solution:
[0007] A cloth chute lining plate replaceable mounting structure, comprising an outer shell and a lining plate, a heavy impact reinforcing plate and a sliding mounting assembly for sliding the heavy impact reinforcing plate along the length direction of the outer shell are installed on the inner bottom wall of the lining plate, and a fixing member for fixing the heavy impact reinforcing plate is further included.
[0008] By adopting the technical scheme, when the heavy impact reinforcing plate is seriously worn, only the single component needs to be replaced, thereby effectively avoiding the early scrapping of the entire cloth chute due to local wear, which greatly prolongs the overall service life of the cloth chute, reduces the need for frequent replacement of equipment, and ensures long-term stable operation of the equipment.
[0009] On the one hand, the purchase cost of the equipment caused by the wear of the heavy impact part is avoided. The cost of replacing a heavy impact reinforcing plate is much lower than that of replacing the entire cloth chute, which greatly reduces the equipment replacement cost. On the other hand, the additional costs such as labor cost, equipment transportation and installation cost caused by equipment replacement are reduced. At the same time, the extension of the service life of the equipment also reduces the long-term maintenance cost of the equipment.
[0010] Optionally, the sliding installation assembly comprises a plurality of spaced sliding strips fixed to the inner bottom wall of the lining plate, the length direction of the sliding strips is parallel to the length direction of the shell, and the bottom surface of the heavy impact reinforcing plate is provided with a plurality of sliding rails, the plurality of sliding strips and the plurality of sliding rails correspond to each other and cooperate with each other.
[0011] By adopting the technical scheme, the cooperation of the sliding strips and the sliding rails realizes the rapid installation of the heavy impact reinforcing plate, and the way that the sliding rails are installed on the heavy impact reinforcing plate can avoid the phenomenon that the sliding is affected due to the entry of the furnace charge into the sliding rails.
[0012] Optionally, the sliding strip is provided with a positioning block on the side close to the discharge end of the shell.
[0013] By adopting the technical scheme, the positioning block limits the final installation position of the heavy impact reinforcing plate, prevents the sliding rails on the heavy impact reinforcing plate from slipping off the sliding strips, and plays a limiting and positioning role.
[0014] Optionally, the inner bottom wall of the lining plate is fixed with a material blocking tooth, the length direction of the material blocking tooth is parallel to the width direction of the shell, and the material blocking tooth abuts against the positioning block.
[0015] By adopting the technical scheme, on the one hand, the material blocking tooth further positions and supports the heavy impact reinforcing plate, and on the other hand, the material blocking tooth can break larger furnace charge blocks into smaller furnace charge blocks, so that the furnace charge is more dispersed and uniform.
[0016] Optionally, a support plate is arranged between two adjacent sliding strips, the support plate is located in the heavy impact area of the lining plate, and when the sliding rail abuts against the positioning block, the bottom surface of the heavy impact reinforcing plate is attached to the support plate.
[0017] By adopting the technical scheme, the support plate supports the heavy impact reinforcing plate, so as to avoid the deformation, wear and perforation of the heavy impact reinforcing plate due to the impact of the falling material, and the stress strength of the heavy impact reinforcing plate is improved.
[0018] Optionally, the heavy impact reinforcing plate is provided with a honeycomb grid on the top surface.
[0019] By adopting the technical scheme, the honeycomb grid forms a small cavity capable of storing a certain amount of furnace charge. After the first falling of the material, a certain amount of loose furnace charge is stored in the cavity to form a honeycomb, so as to avoid the direct impact of the subsequent material on the heavy impact reinforcing plate, and the service life of the heavy impact reinforcing plate is prolonged.
[0020] Optionally, a plurality of buffer strips are arranged between the two adjacent sliding strips, the plurality of buffer strips are parallel to the material blocking teeth and are arranged in the length direction of the shell, and the plurality of buffer strips are away from the heavy impact area of the lining plate.
[0021] By adopting the technical scheme, when the blast furnace is fed, the material entering the chute from the tank will generate a large impact force, and the buffer strip can play a certain buffering role, so as to reduce the direct impact of the material on the lining plate, reduce the wear degree of the lining plate, and prolong the service life of the chute.
[0022] Optionally, the fixing member is a bolt fixed between the heavy impact reinforcing plate and the support plate.
[0023] By adopting the technical scheme, the bolt connection makes the heavy impact reinforcing plate convenient to disassemble and assemble.
[0024] In summary, the present application has at least one of the following beneficial technical effects:
[0025] 1. The sliding installation assembly is arranged, so that when the heavy impact reinforcing plate is seriously worn, only the single part needs to be replaced, so that the early scrapping of the entire feeding chute due to local wear can be effectively avoided. This greatly prolongs the overall service life of the feeding chute, reduces the need for frequent replacement of equipment, and ensures the long-term stable operation of the equipment.
[0026] On the one hand, the purchase cost of the equipment caused by the wear of the heavy impact part is avoided. The cost of replacing a heavy impact reinforcing plate is much lower than that of replacing the entire feeding chute, which greatly reduces the equipment replacement cost. On the other hand, the additional costs such as labor cost, equipment transportation and installation cost caused by equipment replacement are reduced. At the same time, the extension of the service life of the equipment also reduces the long-term maintenance cost of the equipment.
[0027] 2. The support plate is arranged to support the heavy impact reinforcing plate, so as to avoid the deformation, wear and perforation of the heavy impact reinforcing plate caused by the impact of the falling material, and improve the stress strength of the heavy impact reinforcing plate;
[0028] 3. The accumulation grid is arranged to form a small cavity capable of storing a certain amount of furnace charge. After the first falling material, a certain amount of loose furnace charge is stored in the cavity to form an accumulation, so as to avoid the direct impact of the subsequent falling material on the heavy impact reinforcing plate, and prolong the service life of the heavy impact reinforcing plate.

DETAILED DESCRIPTION
[0033] The following will be described in detail in combination with the drawings Figures 1-2 The present application will be further described in detail.
[0034] The embodiment of the present application discloses a replaceable mounting structure of a material chute lining plate.
[0035] Referring to Figure 1 A replaceable mounting structure of a material chute lining plate comprises a shell 1 and a lining plate 2, and the lining plate 2 is provided with a heavy impact reinforcing plate 10 and a sliding mounting assembly 3 for sliding the heavy impact reinforcing plate 10 along the length direction of the shell 1 on the inner bottom wall.
[0036] Referring to Figure 1 and Figure 2 The accumulation grid 8 is fixed on the top surface of the heavy impact reinforcing plate 10, and the accumulation grid 8 is arranged to form a small cavity capable of storing a certain amount of furnace charge. After the first falling material, a certain amount of loose furnace charge is stored in the cavity to form an accumulation, so as to avoid the direct impact of the subsequent falling material on the heavy impact reinforcing plate 10, and prolong the service life of the heavy impact reinforcing plate 10.
[0037] Referring to Figure 1 and Figure 2 , the sliding installation assembly 3 includes a plurality of spaced sliding strips 31 fixed on the inner bottom wall of the lining plate 2, which are provided as two in the embodiment of the application, and the length direction of the sliding strips 31 is parallel to the length direction of the shell 1. The bottom surface of the heavy impact reinforcing plate 10 is provided with a plurality of sliding rails 32, and the plurality of sliding strips 31 correspond to the plurality of sliding rails 32 one by one and cooperate with each other.
[0038] Further, referring to Figure 1 and Figure 2 , in order to realize the positioning of the heavy impact reinforcing plate 10, the sliding strip 31 is provided with a positioning block 5 on the side close to the discharge end of the shell 1. When the sliding rail 32 slides to abut against the positioning block 5, the heavy impact reinforcing plate 10 is located in the heavy impact area of the chute. The inner bottom wall of the lining plate 2 is also fixed with a material blocking tooth 6, the length direction of the material blocking tooth 6 is parallel to the width direction of the shell 1, and the material blocking tooth 6 abuts against the positioning block 5. On the one hand, the material blocking tooth 6 supports and positions the heavy impact reinforcing plate 10, and on the other hand, the material blocking tooth 6 can break larger furnace charge blocks into smaller furnace charge blocks, so that the furnace charge is more dispersed and uniform.
[0039] Referring to Figure 1 and Figure 2 , in order to improve the stability of the heavy impact reinforcing plate 10, a support plate 7 is fixed between the two sliding strips 31, and the support plate 7 is located in the heavy impact area of the lining plate 2. When the sliding rail 32 abuts against the positioning block 5, the bottom surface of the heavy impact reinforcing plate 10 is in close contact with the support plate 7. The setting of the support plate 7 supports the heavy impact reinforcing plate 10, so as to avoid the deformation, wear and perforation of the heavy impact reinforcing plate 10 under the impact of the falling material as much as possible, and improve the stress strength of the heavy impact reinforcing plate 10.
[0040] In addition, referring to Figure 1 and Figure 2 , a fixing member 4 for fixing the heavy impact reinforcing plate 10 is also provided, which is a bolt 41 fixed between the heavy impact reinforcing plate 10 and the support plate 7 in the application. The bolt 41 is respectively located at the four corners of the heavy impact reinforcing plate 10.
[0041] Referring to Figure 1 Figure 2 Figure 1 , finally, a plurality of buffer strips 9 are provided between the two sliding strips 31, the plurality of buffer strips 9 are parallel to the material blocking tooth 6 and are spaced apart along the length direction of the shell 1, and the plurality of buffer strips 9 are away from the heavy impact area of the lining plate 2. The purpose of the setting of the buffer strip 9 is that when the blast furnace is charged, the furnace charge entering the chute from the hopper will generate a relatively large impact force, and the buffer strip 9 can play a certain buffering role, reduce the direct impact of the furnace charge on the lining plate 2, reduce the wear degree of the lining plate 2, and prolong the service life of the chute.
[0042] The implementation principle of the installation structure of the replaceable chute lining plate is as follows: the setting of the sliding installation assembly 3 makes it only necessary to replace the single component when the heavy impact reinforcing plate 10 is seriously worn, so that the early scrapping of the entire chute due to local wear can be effectively avoided. This greatly prolongs the overall service life of the chute, reduces the need for frequent replacement of equipment, and ensures long-term stable operation of the equipment.
[0043] On the one hand, the purchase cost of the equipment caused by the wear of the heavy impact part is avoided. The cost of replacing a heavy impact reinforcing plate 10 is much lower than that of replacing the entire chute, greatly reducing the cost of equipment replacement. On the other hand, additional costs such as labor costs, equipment transportation and installation costs are reduced due to equipment replacement. At the same time, the extension of the service life of the equipment also reduces the long-term maintenance cost of the equipment.
