Problems solved by technology

The following problems generally exist in the existing basket mills: First, because many materials are medium-high viscosity or even thixotropic materials, on the one hand, when grinding, a large amount of materials will adhere to the cavity wall of the cylinder body, which not only causes This part of the material cannot be smoothly entered into the grinding basket for grinding, resulting in a reduction in the grinding quality of the material; at the same time, this part of the material may even be fixed on the wall of the cylinder cavity due to solidification, which will cause trouble for the later cleaning operation
If you want to improve the processing accuracy, you will inevitably need to use more advanced processing equipment, which will lead to a sharp increase in the cost of use, which will bring many troubles to the manufacturer.

Embodiment Construction

[0043] For ease of understanding, here in conjunction with accompanying drawing, the concrete structure of the present invention and working mode are further described as follows:

[0044] The invention is a product developed on the basis of a single-shaft grinder with powerful dispersing, grinding and stirring functions. The invention has good adaptability to medium-high viscosity and thixotropic materials, and various stirring methods are optional, such as conventional anchor type, butterfly type, frame type, etc., dispersing grinding and stirring can be carried out at the same time, strong adaptability, and can be According to the characteristics of customers' materials and production process requirements, non-standard customization is carried out. When the present invention is used in practice, it can even have a vacuum-tight cylinder head matching the cylinder body. The inner milling groove of the cylinder head flange is attached with a corrosion-resistant elastic sealing...

Abstract

The invention belongs to the field of grinding equipment, in particular to a concentric double-axis vacuum hydraulic basket grinding machine. The grinding machine comprises a base, a frame, a liftingassembly, a grinding basket and a cylinder. The grinding basket comprises a cylinder body, an end cap and a filter plate. The end cap and the filter plate are vertically coaxially penetrated by a stirring shaft and the stirring shaft is respectively rotatably matched with the end cap and the filter plate. A basket support is coaxially arranged with the stirring shaft but dose not interfere the stirring shaft. The top end of the basket support is matched with the output end of a second power source, and the bottom end of the basket support is coaxially fixed at the end cap for driving the grinding basket to produce a coaxial rotating action opposite to the turning direction of the stirring shaft. A cantilever extends radially outwardly at the outer wall of the grinding basket, and the extending end of the cantilever arm is fixedly connected with a scraper for scraping the attachment at the wall of a cylinder chamber. The invention has the advantages of high grinding efficiency, good stirring effect, good product fineness, convenient and reliable operation.

Description

technical field [0001] The invention belongs to the field of grinding equipment, in particular to a concentric double-shaft vacuum hydraulic basket grinder. Background technique [0002] The production of the basket grinder is a supplement to the limitations of traditional grinding equipment such as horizontal sand mills and vertical sand mills. The frame of the basket mill is fixed with a grinding basket, which contains grinding media such as zirconia beads. When working, the grinding basket is submerged in the material, the stirring shaft in the grinding basket moves at high speed, and the pumping impeller coaxially fixed on the stirring shaft generates strong suction, sucking the material into the basket with grinding media for dispersion, grinding, and grinding. The material that reaches the standard will be squeezed out of the grinding basket along the filter screen, while the material that does not meet the grinding standard will be intercepted in the grinding chamber...
