Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically a scraper structure for centrifuge unloading. Background Technology

[0002] A centrifuge is a device that uses centrifugal force to separate liquids from solid particles or mixtures of liquids. In chemical and fertilizer production, centrifuges are indispensable and widely used in processes such as solid-liquid separation, purification, and concentration. As a type of centrifuge, the scraper centrifuge, with its efficient and continuous separation capabilities, has become an important tool in chemical and fertilizer production. The centrifuge scraper is a key functional component, used to scrape material off the screen basket inside the centrifuge. However, most existing centrifuge scrapers are one-piece designs, meaning the blade and the scraper body are cast as a single piece. The drawback of this design is that once the blade is damaged, the entire scraper becomes unusable and needs to be replaced, which is wasteful of resources. Utility Model Content

[0003] The purpose of this invention is to provide a scraper structure for centrifuge unloading to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A scraper structure for centrifuge unloading includes:

[0006] The base has a connection notch, an annular notch and a threaded groove on its top, and multiple insertion slots are evenly provided on the outer side wall of the base. Multiple scraper bodies are provided on the outer side of the base, and insertion plates are fixedly connected to each of the multiple scraper bodies. The multiple insertion plates are respectively inserted into the corresponding insertion slots, and limit slots are provided on the insertion plates.

[0007] A fixing mechanism is provided on the top of the base;

[0008] A shielding mechanism is disposed on top of the fixing mechanism.

[0009] Furthermore, the outer contour of the plug plate is the same as the inner contour of the plug slot, and the length of the plug plate is less than the length of the scraper body.

[0010] Furthermore, the fixing mechanism includes:

[0011] A connecting ring is disposed inside the connecting notch. The connecting ring has multiple placement slots, and the inner bottom surface of the placement slot has an insertion hole. One end of the placement slot has a sliding groove, and the inner top surface of the sliding groove has a positioning hole.

[0012] Multiple movable blocks are respectively disposed inside the placement slot. One end of each movable block is wedge-shaped, and a limiting block is fixedly connected to the bottom of each movable block. One side of the compression spring is also wedge-shaped. The limiting block passes through the insertion hole and is inserted into the corresponding insertion slot. A compression spring is fixedly connected between the top of each movable block and the top surface of the placement slot. A limiting component is provided at one end of each movable block.

[0013] Preferably, the limiting component includes a pressing block, which is slidably connected to a corresponding sliding groove, and one end of the pressing block is in pressing contact with the wedge-shaped end of the moving block.

[0014] Preferably, the extrusion block has a rectangular groove, a positioning block is slidably connected inside the extrusion block, and a compression spring is fixedly connected between the bottom of the positioning block and the bottom surface of the rectangular groove. The top of the positioning block is engaged with the corresponding positioning hole.

[0015] Preferably, the connecting ring has multiple bolt holes, and each bolt hole is screwed with a fixing bolt, the bottom of which is screwed with the base.

[0016] Furthermore, the blocking mechanism includes:

[0017] A cover plate is disposed inside the annular notch;

[0018] A threaded tube is fixedly connected to the bottom of the cover plate, and the threaded tube is screwed into a threaded groove.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By setting a fixing mechanism on the top of the base, and by inserting multiple plug-in plates into the corresponding plug-in slots respectively, the fixing mechanism facilitates the limiting and fixing of multiple plug-in plates. By resetting the extrusion block, moving block and limiting block, the limiting block is separated from the corresponding limiting slot, which facilitates the disassembly and replacement of one scraper body. If multiple fixing bolts are removed, the fixing mechanism can be removed, and the multiple limiting blocks can be separated from the corresponding limiting slots respectively, which facilitates the removal of the entire scraper body for cleaning or replacement. This makes it more convenient to use. Moreover, by replacing the scraper body, it is not necessary to replace the entire scraper structure for centrifuge unloading, which improves the practicality of the scraper structure for centrifuge unloading.

[0021] 2. By setting a shielding mechanism on the top of the fixing mechanism, and by screwing the threaded tube into the threaded groove, it is easy to fix the cover plate. The fixed threaded tube shields the top of the fixing mechanism, thereby preventing materials from entering the interior of multiple placement slots, multiple sliding slots and multiple bolt holes, which would affect the normal use of the fixing mechanism. In addition, the fixed threaded tube can provide auxiliary fixation for the fixing mechanism, ensuring the stability of the centrifuge unloading scraper structure during use.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-7 In this embodiment of the present invention, a scraper structure for centrifuge unloading includes a base 100, a fixing mechanism 200, and a shielding mechanism 300. The top of the base 100 is provided with a connecting notch 101, an annular notch 103, and a threaded groove 104. A plurality of insertion slots 102 are evenly provided on the outer side wall of the base 100. A plurality of scraper bodies 110 are provided on the outer side of the base 100, and each of the plurality of scraper bodies 110 is fixedly connected with an insertion plate 120. The plurality of insertion plates 120 are respectively inserted into the corresponding insertion slots 102, and a limiting groove 121 is provided on the insertion plate 120. The fixing mechanism 200 is provided on the top of the base 100, and the shielding mechanism 300 is provided on the top of the fixing mechanism 200.

[0032] Specifically, by inserting multiple plug-in plates 120 into corresponding plug-in slots 102, and using a fixing mechanism 200 to limit and fix the multiple plug-in plates 120, the installation of multiple scraper bodies 110 is completed. The fixing mechanism 200 allows for quick disassembly and replacement of the scraper bodies 110 and plug-in plates 120. Furthermore, the shielding mechanism 300 provides shielding protection for the top of the fixing mechanism 200 and provides auxiliary fixation, thereby ensuring the stability of the centrifuge unloading scraper structure during use.

[0033] Example 1

[0034] like Figure 2-6As shown, in this embodiment, the outer contour of the plug-in plate 120 is the same as the inner contour of the plug-in groove 102, and the length of the plug-in plate 120 is less than the length of the scraper body 110. The fixing mechanism 200 includes: a connecting ring 210 and a plurality of moving blocks 230. The connecting ring 210 is disposed inside the connecting notch 101. The connecting ring 210 has a plurality of placement grooves 211, and the inner bottom surface of the placement groove 211 has a plug-in hole 212. One end of the placement groove 211 has a sliding groove 213, and the inner top surface of the sliding groove 213 has a positioning hole 214. The plurality of moving blocks 230 are respectively disposed inside the placement groove 211. One end of the moving block 230 is wedge-shaped, and the bottom of the moving block 230 is fixedly connected to a limit block 232, and the pressure... One side of the compression spring 231 is wedge-shaped. The limiting block 232 passes through the insertion hole 212 and is inserted into the corresponding insertion groove 102. The top of the moving block 230 is fixedly connected to the top surface of the corresponding placement groove 211. One end of the moving block 230 is provided with a limiting component, which includes a pressing block 240. The pressing block 240 is slidably connected to the corresponding sliding groove 213, and one end of the pressing block 240 is pressed against the wedge-shaped end of the moving block 230. A rectangular groove 241 is opened on the pressing block 240. A positioning block 250 is slidably connected inside the pressing block 240, and a compression spring 251 is fixedly connected between the bottom of the positioning block 250 and the bottom surface of the rectangular groove 241. The top of the positioning block 250 is engaged with the corresponding positioning hole 214.

[0035] In this embodiment, when multiple plug-in plates 120 are respectively plugged into the corresponding plug-in slots 102, and the fixing mechanism 200 is fixed at the connection notch 101, the pressing block 240 is pushed to move, and the moving pressing block 240 presses the wedge-shaped end of the moving block 230, causing the moving block 230 and the limiting block 232 to move downward, so that the limiting block 232 passes through the plug-in hole 212 and plugs into the corresponding limiting slot 121, thereby fixing the installed plug-in plate 120 and scraper body 110. When the pressing block 240 moves, it will drive the positioning block 250 to move, and when the positioning block 250 is aligned with the positioning hole 214... Correspondingly, the compression spring 251 pushes the positioning block 250 to engage with the positioning hole 214, thereby fixing the position of the pressing block 240, and thus fixing the positions of the moving block 230 and the limiting block 232. If it is necessary to insert the scraper body 110, the positioning block 250 is pressed into the interior of the rectangular groove 241, and the pressing block 240 is pushed to move and reset. The compression spring 231 pulls the moving block 230 and the limiting block 232 to reset, thereby separating the limiting block 232 from the corresponding limiting groove 121. This makes it easier to disassemble and replace the insertion plate 120 and the scraper body 110, making it more convenient to use.

[0036] like Figure 4-6As shown, in this embodiment, the connecting ring 210 has multiple bolt holes 215, and each bolt hole 215 is screwed with a fixing bolt 220. The bottom of each fixing bolt 220 is screwed with the base 100.

[0037] In practice, multiple bolt holes 215 and multiple fixing bolts 220 are used to facilitate the installation and fixing of the fixing mechanism 200 to the top of the base 100. If the multiple fixing bolts 220 are removed, the fixing mechanism 200 can be removed, and the multiple limiting blocks 232 can be separated from the corresponding limiting grooves 121, thereby facilitating the quick insertion of multiple scraper bodies 110, making it more convenient to use.

[0038] Example 2

[0039] Based on Embodiment 1, in order to shield the top of the fixing mechanism 200 and prevent materials from entering the interior of the multiple placement slots 211, multiple sliding slots 213 and multiple bolt holes 215, thus affecting the use of the fixing mechanism 200.

[0040] like Figure 7 As shown, in this embodiment, the shielding mechanism 300 includes a cover plate 310 and a threaded tube 320. The cover plate 310 is disposed inside the annular notch 103, and the threaded tube 320 is fixedly connected to the bottom of the cover plate 310. The threaded tube 320 is screwed into the threaded groove 104.

[0041] In specific implementation, the threaded tube 320 is screwed into the threaded groove 104 to facilitate the fixing of the cover plate 310. When the threaded tube 320 is tightened, the rotation direction is opposite to the rotation direction when the centrifuge unloading scraper structure is in use, so that the threaded tube 320 is not easy to rotate and fall off when the centrifuge unloading scraper structure is in use. The fixed threaded tube 320 is used to cover the top of the fixing mechanism 200, thereby preventing materials from entering the interior of the multiple placement grooves 211, multiple sliding grooves 213 and multiple bolt holes 215, which would affect the normal use of the fixing mechanism 200. The fixed threaded tube 320 can also provide auxiliary fixing for the fixing mechanism 200.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
