Description

Technical Field

[0001] The utility model relates to the technical field of cyclones, in particular to a cyclone with an inner lining that is easy to replace. Background Art

[0002] The wear of the cyclone lining is mainly concentrated in the lower part of the cone section. This is because the slurry flow rate in this area is the fastest and the impact force of the solid particles is the greatest, causing the lining material to be subjected to severe friction and impact, resulting in wear.

[0003] The lining of the cone section of the existing cyclone is generally a ceramic one-piece molded structure. Therefore, when the bottom of the cone section is worn, the lining of the entire cone section needs to be replaced, resulting in a short overall service life of the lining and high maintenance costs. Utility Model Content

[0004] The utility model aims to provide a cyclone with an easy-to-replace inner lining. The inner lining has a long overall service life, is easy to install and repair and replace, and can reduce maintenance costs.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a cyclone with an easy-to-replace liner, comprising a straight cylinder section at the upper part and a conical cylinder section at the lower part, wherein a liner assembly is installed in the conical cylinder section; the liner assembly comprises a plurality of annular splicing units nested in each other up and down, and each splicing unit is adapted to the inner wall of the conical cylinder section; an annular plug-in block is provided at the bottom of the splicing unit, and an annular slot for inserting the plug-in block of the upper splicing unit is provided at the top of the splicing unit.

[0006] After adopting the above structure, the lining assembly is composed of multiple annular splicing units nested in each other up and down. Therefore, when the bottom lining of the cone section is severely worn, the lining assembly can be disassembled and part of the lining assembly can be selectively replaced without replacing the entire lining assembly, thereby increasing the overall service life of the lining assembly and reducing maintenance costs; the lining assembly is assembled in a nested manner, which facilitates installation and maintenance and replacement, and improves maintenance speed.

[0007] In order to ensure the position accuracy between the two adjacent splicing units and improve the connection stability, a number of mutually cooperating positioning posts and positioning grooves are evenly provided on the top of the slot and the bottom of the plug-in block of the splicing unit above, and the positioning posts are inserted into the positioning grooves.

[0008] In order to avoid stress concentration at sharp corners and ensure the positioning accuracy of the positioning column and the positioning groove, the positioning column and the positioning groove are elliptical.

[0009] In order to further reduce the replacement cost, the splicing unit is enclosed by multiple arc-shaped unit components connected end to end; adjacent unit components are connected by a plug-in structure; the plug-in structure includes a snap-in groove arranged at one end of the unit component and a connecting part arranged at the other end thereof; the connecting part and the snap-in groove are adapted to each other, and two adjacent unit components are snap-in to each other through the connecting part and the snap-in groove.

[0010] In order to achieve more degrees of freedom in limiting, the clamping groove is a dovetail groove; the connecting part is a trapezoidal head that matches the dovetail groove.

[0011] In order to limit the installation of adjacent unit components and ensure the flatness of the spliced ​​unit, a limit plate is set at the bottom of the dovetail groove. After the bottom of the connecting part contacts the limit plate, the tops of the two adjacent unit components are flush.

[0012] In order to position each unit assembly, a set of positioning posts and positioning grooves are provided on the top and bottom of each unit assembly.

[0013] In order to have high versatility, facilitate replacement, and simplify the splicing process, each annular splicing unit is enclosed by six unit components.

[0014] After adopting the above technical solution, the beneficial effects of the utility model are:

[0015] The utility model provides a cyclone with an easy-to-replace liner, which solves the technical problems in the prior art of high replacement and maintenance costs of the cyclone liner and short service life of the liner. The utility model provides an assembleable liner component, which can selectively replace part of the worn liner component according to the wear condition, thereby increasing the overall service life of the liner component and reducing maintenance costs.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] The orientations mentioned in this specification are based on the orientations of the cyclone for easy replacement of the inner liner of the present invention during normal operation, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0028] Example 1:

[0029] like Figure 1 、 Figure 2 and Figure 3 As shown together, a cyclone with easy replacement of liner includes a straight cylinder section 1 at the upper portion and a conical cylinder section 2 at the lower portion, wherein a liner assembly 3 is installed in the conical cylinder section 2.

[0030] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown together, the lining assembly 3 includes a plurality of annular splicing units 31 nested one above the other, and each splicing unit 31 is adapted to the inner wall of the cone section 2 .

[0031] The nesting mode of the upper and lower adjacent splicing units 31 is as follows:

[0032] An annular plug-in block 311 is provided at the bottom of the annular splicing unit 31, and an annular slot 312 is provided at the top of the splicing unit 31 for inserting the plug-in block 311 of the upper splicing unit 31; during installation, the plug-in block 311 of the upper splicing unit 31 is inserted into the slot 312 of the lower splicing unit 31, thereby realizing the nesting of the upper and lower adjacent splicing units 31.

[0033] like Figure 4 and Figure 5As shown, a number of cooperating positioning posts 313 and positioning slots are evenly distributed along the circumference of the top of the slot 312 and the bottom of the insert 311. The positioning posts 313 are inserted into the positioning slots. In this embodiment, the positioning posts 313 are located above the inner bottom of the slot 312, while the positioning slots are located on the bottom of the insert 311. In actual applications, the positioning posts 313 can be located at the bottom of the insert 311, while the positioning slots can be located above the inner bottom of the slot 312. This embodiment is not limited to this.

[0034] It is worth noting that the positioning grooves and the positioning posts 313 are respectively provided on both sides of the splicing unit 31 , and the two adjacent splicing units 31 can be positioned by the cooperation of the positioning grooves and the positioning posts 313 , thereby improving the connection stability.

[0035] It is also worth noting that in this embodiment, the positioning groove and the positioning post 313 are clearance-fitted. Setting the positioning groove and the positioning post 313 as a clearance-fit connection facilitates assembly and disassembly, and can ensure the positioning accuracy of the splicing unit 31 while reducing assembly and disassembly difficulty, improving splicing efficiency, and reducing the labor intensity of workers.

[0036] The positioning post 313 and the positioning groove are oval in shape. The oval positioning post 313 has a high positioning accuracy, which prevents the upper and lower adjacent splicing units 31 from being misaligned. In addition, the oval positioning post 313 does not have sharp corners to avoid being broken.

[0037] Example 2:

[0038] like Figure 6-Figure 9 As shown, the splicing unit 31 is formed by a plurality of arc-shaped unit components 32 connected end to end. In this embodiment, each splicing unit 31 is formed by six unit components 32. The six unit components 32 have high versatility, are easy to replace, and can simplify the splicing process. Adjacent unit components 32 are connected by plug-in structures 33.

[0039] The plug-in structure 33 includes a snap-in slot 331 provided at one end of the unit assembly 32 and a connecting portion 332 provided at the other end thereof; the connecting portion 332 and the snap-in slot 331 are adapted to each other, and two adjacent unit assemblies 32 are snap-connected to each other through the connecting portion 332 and the snap-in slot 331 .

[0040] In order to achieve more degrees of freedom in limiting, the engaging groove 331 is a dovetail groove; the connecting portion 332 is a trapezoidal head that matches the dovetail groove.

[0041] When the connecting portion 332 is inserted into the snap-fitting groove 331 , a limiting plate is provided at the bottom of the dovetail groove to achieve bottom limiting. When the bottom of the connecting portion 332 contacts the limiting plate, the tops of the two adjacent unit assemblies 32 are flush.

[0042] In order to mass-produce the unit components 32 , a set of positioning posts 313 and positioning grooves are provided on the top and bottom of each unit component 32 .

[0043] The utility model provides a cyclone with an easy-to-replace liner, which solves the technical problems in the prior art of high replacement and maintenance costs of the cyclone liner and short service life of the liner. The utility model provides an assembleable liner component, which can selectively replace part of the worn liner component according to the wear condition, thereby increasing the overall service life of the liner component and reducing maintenance costs.

[0044] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
