Description

Technical Field

[0001] This utility model relates to the field of sand mills, and in particular to a sand mill. Background Technology

[0002] A sand mill is a highly efficient and advanced wet ultrafine grinding equipment. The working principle of a sand mill is that a motor drives the grinding media (such as zirconium beads) to rotate at high speed, causing the material and grinding media to generate strong collisions, friction, and shearing effects within the cylinder, thereby achieving the purpose of grinding and dispersing the material. Depending on the structure, sand mills can be divided into vertical sand mills and horizontal sand mills, etc. Sand mills are widely used in chemical, metallurgical, mining, non-metallic mineral materials, ceramics, and new materials fields, especially for the crushing and grinding of raw materials such as nanomaterials, ceramic materials, lithium battery materials, paints, and inks. Sand mills have advantages such as wide material adaptability, high grinding efficiency, and high energy density. Combined with a high-quality cooling system and automatic control system, continuous material processing and continuous discharge can be achieved. After use, the grinding cylinder of a sand mill needs to be disassembled for cleaning and maintenance, especially during material transfer or when blockage occurs. However, the grinding cylinder of existing sand mills is installed high up, making disassembly difficult. Utility Model Content

[0038] The following is for reference. Figures 1-3A sand mill is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0039] like Figures 1-3 As shown, a sand mill includes a machine base 100, a grinding device, and a transfer trolley.

[0040] The machine base 100 has a mounting base 110 and a first guide rail 120 on its top surface; the grinding device includes a grinding motor 130 and a grinding barrel 140. The grinding motor 130 is mounted on the mounting base 110, and the side of the mounting base 110 is provided with a flange 150 connected to the grinding barrel 140. The bottom of the grinding barrel 140 is provided with a guide wheel 160 and is mounted on the first guide rail 120. The grinding barrel 140 is provided with a grinding shaft 170, and the grinding shaft 170 is provided with a coupling 180 that is detachably connected to the output shaft of the grinding motor 130; the transfer trolley includes a base 190, a lifting mechanism 200 and a top plate 210. The lifting mechanism 200 is mounted on the base 190 to drive the top plate 210 to rise and fall. The top plate 210 is provided with a second guide rail 220 that is connected to the first guide rail 120. When cleaning or maintenance is required, the grinding barrel 140 is separated from the flange 150, and then the grinding barrel 140 is pushed from the first guide rail 120 to the second guide rail 220. The lifting mechanism 200 on the base carriage 190 lowers the top, thus lowering the grinding barrel 140 to a lower position for easy cleaning or maintenance. Additionally, the grinding shaft 170 can also be separated from the output shaft of the grinding motor 130 by removing the coupling 180, making it easy to remove for subsequent cleaning and maintenance. After cleaning and maintenance, the output shaft and coupling 180 are first installed on the grinding motor 130. Then, the lifting mechanism 200 raises the top plate 210, aligning the second guide rail 220 on the top plate 210 with the first guide rail 120 of the machine base 100. The grinding barrel 140 is then pushed to one side of the first guide rail 120 and aligned with the flange 150, secured with screws to complete the installation process. Therefore, this sand mill is easy to disassemble and assemble, facilitating cleaning and maintenance, and improving the efficiency of disassembly, cleaning, and maintenance.

[0041] Specifically, the machine tool 100 has a first docking block 230 on the side facing the transfer trolley, and the first docking block 230 has a first docking hole. The transfer trolley has a second docking block 240 on the side facing the machine tool 100, which mates with the first docking block 230. The second docking block 240 has a second docking hole that mates with the first docking hole. The first docking hole and the second docking hole are connected by a docking pin 250. Through the mating of the first docking block 230 and the second docking block 240, and the connection of the first docking hole and the second docking hole through the docking pin 250, the positions of the transfer trolley and the machine tool 100 are fixed, ensuring accurate docking of the first guide rail 120 and the second guide rail 220, thereby guaranteeing the smooth transfer of the grinding barrel 140 from the first guide rail 120 to the second guide rail 220. Moreover, as... Figure 2As shown, the bottom of the grinding barrel 140 is provided with two parallel support rods 260, and guide wheels 160 are provided at both ends of the support rods 260. The support rods 260 facilitate the installation of the guide wheels 160 on the grinding barrel 140, so that the grinding barrel 140 can move on the first guide rail 120 and the second guide rail 220 through the guide wheels 160.

[0042] It should be noted that, as Figure 3 As shown, the guide wheel 160 is equipped with a stopping mechanism 270. The stopping mechanism 270 allows the grinding drum 140 to stop when it does not need to move, preventing it from falling off the machine base 100 or the transfer trolley. Specifically, the mounting base 110 is a housing, and the grinding motor 130 is integrally mounted within it. The housing design of the mounting base 110 facilitates the installation of the grinding motor 130 and the mating of the grinding motor 130 with the grinding drum 140. Additionally, a sealed bearing 280 is provided between the flange 150 and the side of the grinding drum 140. The sealed bearing 280 serves as a seal to prevent leakage during the grinding process. Furthermore, the top of the grinding drum 140 has a feed inlet 290, which is equipped with a feed hose 300. The feed inlet 290 and feed hose 300 allow raw materials to enter the grinding drum 140 and can be separated from it during disassembly. Correspondingly, the grinding barrel 140 has a discharge port 310 on the outward-facing side of its top, and the discharge port 310 is controlled by a discharge valve 320. The discharge port 310 and the discharge valve 320 facilitate discharge and control the discharge speed, allowing cleaning to be performed after discharge is completed.

[0043] It is understandable that, such as Figure 3 As shown, the inner wall of the grinding barrel 140 is provided with an anti-stick coating 330. The anti-stick coating on the inner wall of the grinding barrel 140 reduces the adhesion of raw materials to the wall, which is beneficial for cleaning, reduces cleaning time, and improves cleaning efficiency.

[0044] It is worth mentioning that, such as Figure 1 As shown, the lifting mechanism 200 is an electric scissor lift. The electric scissor lift structure of the lifting mechanism 200 is simple and easy to control.

[0045] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
