Description

Technical Field

[0001] This utility model relates to the field of sand mill technology, specifically a horizontal sand mill for laboratory use that is easy to clean. Background Technology

[0002] A horizontal sand mill is a horizontal, wet, continuous production equipment that achieves ultrafine particle dispersion by filling with grinding media (such as glass beads or zirconia beads). It is suitable for nanoscale grinding processes of high-viscosity materials such as coatings, inks, and pharmaceuticals. Its structure mainly consists of a grinding barrel, dispersing blades, a dynamic separation system, and a feed pump. It adopts a fully enclosed design to reduce solvent evaporation and ensure production safety and stability. In laboratory use, the horizontal sand mill is a horizontal, wet, continuous ultrafine sand milling device designed specifically for fine chemical fields such as nanomaterials, pharmaceutical preparations, and battery slurries. It achieves submicron to nanoscale dispersion through efficient shearing and collision between the grinding media and materials, meeting the needs of small-batch, high-precision research and development in laboratories. The sand mill is generally small in size.

[0003] The existing laboratory horizontal sand mill mainly consists of a sand mill cylinder, a dispersion device, and a dynamic separation system. In use, a solvent or lubricating oil that is miscible with the material is first injected into the mechanical seal chamber to ensure that the sealing system works normally. The sand milling medium is then filled through the top sand filling port, the cooling water circulation system is connected, and the feed pump is started. After a stable material flow is seen from the discharge port, the main motor is started to perform sand milling on the internal material. During the process, the material is discharged through a screening structure.

[0004] When cleaning the aforementioned sand mill after use, it is necessary to gradually separate and disassemble the cylinder, motor drive, and internal dispersion device to facilitate subsequent cleaning. However, during the disassembly process, the cylinder needs to be manually removed, and the disassembly process is cumbersome and inconvenient. Therefore, we propose a horizontal sand mill for laboratory use that is easy to clean. Utility Model Content

[0028] This utility model provides, for example Figure 1-4 The illustrated horizontal sand mill for easy cleaning in the laboratory includes a main frame 1, with a sand milling assembly 2 connected to one end of the main frame 1. The main frame 1 includes a base frame 101, with a pad 102 fixed to the bottom surface of the base frame 101. An equipment rack 103 is fixed to one end of the base frame 101, a cover 206 is fixed to one side of the equipment rack 103, and a sealing plate 104 is engaged on the other side of the equipment rack 103. Screws 105 are distributed on the outer wall of the sealing plate 104.

[0029] To maintain the structural stability of the entire device during operation, such as Figure 1 As shown, this horizontal sand mill is fixedly composed of a base frame 101 and an equipment frame 103, which provides lateral connection stability and bottom support for the horizontal sand mill assembly 2. The bottom of the base frame 101 is kept stable by a uniformly fitted pad 102, and can be easily disassembled, inspected and maintained by the sealing plate 104 on one side of the equipment frame 103.

[0030] like Figure 2-4 As shown, the sanding assembly 2 includes a sanding cylinder 201. A sliding bracket 202 is fixed to the bottom of the sanding cylinder 201. A transmission screw 203 is threaded to the center of the sliding bracket 202. An auxiliary motor 204 is shaft-connected to one end of the transmission screw 203. A rubber ring 205 is fitted to the opening at one end of the sanding cylinder 201. A cover 206 is engaged at the opening at one end of the sanding cylinder 201. A bearing ring 207 is sleeved at the center of the cover 206. The inner wall of the bearing ring 207 is fitted with... A feed shaft 208 is provided. One end of the feed shaft 208 is connected to a drive wheel 210 via a drive belt 209. One end of the drive wheel 210 is connected to a main motor 211. A grinding shaft 212 is fixed at the center of the other end of the feed shaft 208. A grinding disc 213 is fixed around the grinding shaft 212. A screen-moving separation frame 214 is fixed at one end of the grinding shaft 212. A bearing frame 215 is sleeved on one end of the screen-moving separation frame 214. A scraper ring 216 is fixed around the bearing frame 215.

[0031] To facilitate cleaning of the interior of the overall sand mill, such as Figure 2-4 As shown, the sanding part of this horizontal sand mill consists of a sand mill cylinder 201 and a cover 206. The cover 206 is fixed by the equipment frame 103, while the sand mill cylinder 201 is sealed to one side of the cover 206 by a rubber ring 205. Before cleaning, the transmission screw 203 can be driven by the auxiliary motor 204, and then the transmission screw 203 drives the sliding bracket 202 and the sand mill cylinder 201. The sand mill cylinder 201, the cover 206 and the sand mill shaft 212 inside are separated synchronously, realizing a quick disassembly process, which makes it convenient for users to perform subsequent cleaning and maintenance.
