Description

Technical Field

[0001] This utility model relates to the field of sand mill technology, and in particular to a centrifugal separator anti-clogging sand mill. Background Technology

[0002] Sand mills are currently the most adaptable, advanced, and efficient grinding equipment for materials. They are divided into horizontal and vertical sand mills. The working principle of a vertical sand mill is that the dispersing disc drives the grinding media to move at high speed, generating friction and shearing, so that the material is ground and dispersed. It is a highly efficient grinding and dispersing equipment widely used in industrial fields such as paint coatings, cosmetics, food, daily chemicals, dyes, inks, pharmaceuticals, ferrites, and photosensitive films.

[0003] Traditional sand mill screen discharge separation devices are prone to clogging when the material added to the chamber has a high viscosity, causing the screen to become clogged under conveying pressure, resulting in machine shutdown. Cleaning the screen after shutdown is also a time-consuming and labor-intensive task, which is detrimental to subsequent production and reduces production efficiency. To address these issues, we have introduced a centrifugal separator anti-clogging sand mill. Utility Model Content

[0004] This utility model discloses a centrifugal separator anti-clogging sand mill, which improves upon the existing structure and deficiencies mentioned above, and provides a centrifugal separator anti-clogging sand mill to achieve better practical value.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A centrifugal separator anti-clogging sand mill includes a sand mill body. A controller and a printer are respectively installed on one side of the sand mill body. Rollers are fixedly connected to the bottom of the sand mill body. An outer cylinder is fixedly connected to one side of the sand mill body. A rotating rod is rotatably connected inside the outer cylinder. The rotating rod is a hollow structure. A mounting rod is fixedly connected to the bottom of the rotating rod. Outer grinding discs are fixedly connected at equal intervals to the outer side of the mounting rod. A drive assembly is installed inside the sand mill body to drive the rotating rod to rotate. A [missing information - likely a device or component] is located at the bottom of the outer cylinder. A sealing plate has a feed inlet fixedly connected to its bottom, a discharge outlet fixedly connected to the outer side of the rotating rod, a limiting component fixedly provided on the top of the sealing plate for fixing the sealing plate, a water inlet and a water outlet fixedly connected to the outer side of the outer cylinder, a connecting groove equally spaced inside the mounting rod, a separator provided on the outer side of the mounting rod, an inner liner provided on the outer side of the mounting rod, a flange fixedly connected to the top of the inner liner, the top of the flange being fixed to the top of the inner wall of the outer cylinder by bolts, and a cleaning component provided inside the inner liner.

[0007] In a preferred embodiment, the cleaning assembly includes a connecting rod that is equidistantly slidably connected inside the inner liner. One end of the connecting rod is fixedly connected to a cleaning plate, and one side of the cleaning plate is fixedly connected to bristles at equal intervals. One end of the connecting rod is threadedly connected to a limit block.

[0008] In a preferred embodiment, a spring is provided on the outer side of the connecting rod, between one side of the cleaning plate and one side of the inner wall of the inner liner.

[0009] In a preferred embodiment, the drive assembly includes a motor disposed inside the sand mill body, and pulleys are fixedly connected to both the output shaft of the motor and the outer side of the rotating rod, with belts disposed on the outer side of the pulleys.

[0010] In a preferred embodiment, the limiting component includes a locking block, which is fixedly connected to the top of the sealing plate at equal intervals. The outer cylinder has slots at equal intervals inside, and the bottom of the locking block abuts against the bottom of the inner wall of the slot.

[0011] In a preferred embodiment, a collar is rotatably connected to the outer side of the outer cylinder, and compression blocks are fixedly connected at equal intervals inside the collar. The outer side of the compression blocks is slidably connected to the inside of the outer cylinder.

[0012] In a preferred embodiment, the top of the card block is provided with an arc surface, and one side of the compression block is provided with a slope.

[0013] In a preferred embodiment, the inner liner is provided with equidistant inner grinding discs.

[0014] The centrifugal separator anti-clogging type sand mill provided by this utility model has the following advantages:

[0015] Firstly, by installing a cleaning mechanism inside the device, the adhering substances on the outside of the separator are automatically removed, which effectively reduces the risk of separator blockage in the case of high viscosity materials and reduces the frequency of shutdown due to blockage. Through high-frequency rotation, the brush bristles can thoroughly clean the separator, ensuring that the separator is always unobstructed and improving the screening efficiency of materials after sand milling.

[0016] Secondly, by utilizing the curved surface of the top of the locking block, during the installation of the sealing plate, the curved surface contacts the corner of the outer cylinder. Under pressure, the locking block bends inward, allowing it to enter the outer cylinder and into the locking groove, fixing the sealing plate to the bottom of the outer cylinder and ensuring its airtightness. When the sealing plate needs to be removed, simply rotate the collar, causing the pressing block to rotate, allowing the inclined surface of the pressing block to contact the locking block. Continue rotating, causing the pressing block to squeeze the locking block into the outer cylinder, disengaging it from the locking groove, allowing the sealing plate to be removed. The limiting component enables quick disassembly and installation of the sealing plate, facilitating maintenance and replacement operations, reducing downtime, and improving the overall operating efficiency of the production line.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] The centrifugal separator anti-clogging sand mill disclosed in this utility model is mainly used in sand mill applications.

[0025] Reference Figures 1 to 5 A centrifugal separator anti-clogging type sand mill includes: a sand mill body 1, a controller 2 and a printer 3 respectively installed on one side of the sand mill body 1, rollers 4 fixedly connected to the bottom of the sand mill body 1, an outer cylinder 5 fixedly connected to one side of the sand mill body 1, a rotating rod 6 rotatably connected inside the outer cylinder 5, the rotating rod 6 being a hollow structure, an mounting rod 7 fixedly connected to the bottom of the rotating rod 6, outer grinding discs 8 fixedly connected at equal intervals to the outer side of the mounting rod 7, a drive assembly installed inside the sand mill body 1 for driving the rotating rod 6 to rotate, and a sealing plate 17 installed at the bottom of the outer cylinder 5. The bottom of the sealing plate 17 is fixedly connected to the inlet 18, the outer side of the rotating rod 6 is fixedly connected to the outlet 19, the top of the sealing plate 17 is provided with a limiting component, the limiting component is used to fix the sealing plate 17, the outer side of the outer cylinder 5 is fixedly connected to the inlet 20 and the outlet 21 respectively, the inside of the mounting rod 7 is provided with a connecting groove 11 at equal intervals, the outer side of the mounting rod 7 is provided with a separator 12, the outer side of the mounting rod 7 is provided with an inner liner 9, the top of the inner liner 9 is fixedly connected to the flange 10, the top of the flange 10 is fixed to the top of the inner wall of the outer cylinder 5 by bolts, and the inside of the inner liner 9 is provided with a cleaning component;

[0026] The cleaning assembly includes a connecting rod 13, which is equidistantly slidably connected to the inside of the inner liner 9. One end of the connecting rod 13 is fixedly connected to a cleaning plate 14, and one side of the cleaning plate 14 is fixedly connected to bristles 15 at equal intervals. One end of the connecting rod 13 is threadedly connected to a limit block 16.

[0027] A spring 30 is provided on the outer side of the connecting rod 13, between one side of the cleaning plate 14 and one side of the inner wall of the inner liner 9;

[0028] The drive assembly includes a motor 22, which is located inside the sand mill body 1. The output shaft of the motor 22 and the outer side of the rotating rod 6 are both fixedly connected to pulleys 23, and belts 24 are provided on the outer side of the pulleys 23.

[0029] The limiting component includes a locking block 25, which is fixedly connected to the top of the sealing plate 17 at equal intervals. The outer cylinder 5 has slots 26 at equal intervals inside, and the bottom of the locking block 25 abuts against the bottom of the inner wall of the slot 26.

[0030] In the above technical solution, considering that the traditional screen discharge separation device of the sand mill is prone to screen blockage and shutdown when the viscosity of the material added to the cavity is high under the action of conveying pressure, the screen is easily blocked. Cleaning the screen after shutdown is a time-consuming and laborious task, which is not conducive to subsequent production and reduces production efficiency. To solve this problem, the specific operation is as follows: The sealing plate 17 is installed at the bottom of the outer cylinder 5 using the limiting component. The material is fed into the inner liner 9 from the feed port 18. Then, the motor 22 is started using the drive component, and the transmission action of the pulley 23 and belt 24 drives the rotating rod 6 to rotate. Then, the mounting rod 7 and the outer grinding disc 8 rotate in the inner liner 9 to grind the material. At the same time, the cleaning component, through the elastic force of the spring 30, keeps the cleaning plate 14 in contact with the outside of the separator 12. The rotation of the rotating rod 6 drives the separator 12 to rotate, which is equivalent to the cleaning plate 14 rotating in the opposite direction. The bristles 15 are used to clean the outside of the separator 12. Then, the external pump is connected to the discharge port 19 to suck the ground material into the connecting groove 11 through the separator 12, and then into the discharge port 19 along the inner cavity of the rotating rod 6 and discharged. By installing a cleaning mechanism inside the device, the adhering substances on the outside of the separator 12 are automatically removed, which effectively reduces the risk of blockage of the separator 12 under high viscosity material conditions and reduces the frequency of shutdown due to blockage. Through high-frequency rotation, the brush 15 can thoroughly clean the separator 12, ensuring that the separator 12 is always unobstructed and improving the screening efficiency of the material after sand milling.

[0031] Reference Figures 1 to 5In a preferred embodiment, a collar 27 is rotatably connected to the outer side of the outer cylinder 5, and a pressing block 28 is fixedly connected at equal intervals inside the collar 27. The outer side of the pressing block 28 is slidably connected to the inside of the outer cylinder 5. The top of the locking block 25 is provided with an arc surface, and one side of the pressing block 28 is provided with an inclined surface. By utilizing the arc surface at the top of the locking block 25, when installing the sealing plate 17, the arc surface contacts the corner of the outer cylinder 5. Under pressure, the locking block 25 will bend inward, thereby entering the outer cylinder 5 and the slot 26, fixing the sealing plate 17 to the bottom of the outer cylinder 5, ensuring the sealing performance of the outer cylinder 5. When it is necessary to remove the sealing plate 17, simply rotate the collar 27 to drive the pressing block 28 to rotate, so that the inclined surface of the pressing block 28 contacts the locking block 25. Continue to rotate, so that the pressing block 28 presses the locking block 25 into the outer cylinder 5, so that the locking block 25 disengages from the slot 26, and the sealing plate 17 can be removed. The sealing plate 17 can be quickly disassembled and installed using the limiting components, which facilitates maintenance and replacement operations, reduces downtime, and improves the overall operating efficiency of the production line.

[0032] Reference Figures 1 to 5 In a preferred embodiment, the inner liner 9 is provided with inner grinding discs 29 connected at equal intervals inside;

[0033] Working principle: During use, the material is fed into the inner liner 9 through the feed port 18. Then, the motor 22 is started using the drive assembly, and the rotation of the rotating rod 6 is driven by the transmission action of the pulley 23 and the belt 24. This drives the mounting rod 7 and the outer grinding disc 8 to rotate in the inner liner 9, grinding the material. At the same time, the cleaning assembly, through the elastic force of the spring 30, keeps the cleaning plate 14 in contact with the outside of the separator 12. The rotation of the rotating rod 6 drives the separator 12 to rotate, which is equivalent to the cleaning plate 14 rotating in the opposite direction. The bristles 15 clean the outside of the separator 12. Then, the external pump is connected to the discharge port 19 to suck the ground material through the separator 12 into the connecting groove 11, and then into the discharge port 19 along the inner cavity of the rotating rod 6 and discharged. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
