Description

Technical Field

[0001] The utility model relates to the technical field of disperse dyes, in particular to a filter press structure for safe production. Background Art

[0002] In the dye production process, solid-liquid separation technology has always played an important role. Especially in the process of preparing disperse dyes, how to achieve efficient, safe and environmentally friendly solid-liquid separation has always been an important issue facing the industry. Filter pressing refers to a physical filtration technology that uses pressure to separate solid matter from liquid through filter media. At the same time, in the dye production process, solid-liquid separation is a key link to ensure product quality and production efficiency. The working principle of the filter press is mainly to use pressure to separate solid matter from the suspension. Filter pressing can handle high-concentration, high-temperature, and high-viscosity materials. For some difficult-to-handle materials, such as suspended particles, colloids, etc., filter pressing is relatively more advantageous.

[0003] The Chinese patent discloses: a filter press, patent application number: 202221132397.6, which "includes: a frame, a filter press plate and a limit assembly; a plurality of filter press plates are sequentially attached and arranged on the frame; support seats are respectively provided on both sides of the filter press plate; a limit base is installed on the frame; the limit base is provided with a first limit opening; the support seat is provided with a second limit opening; the limit block is provided at the first limit opening; one end of the limit block is provided with a first inclined surface, and the driving block is provided with a second inclined surface; the driving block is used to drive the limit block to move horizontally, and the second inclined surface is attached to the first inclined surface; the driving block moves up and down, and drives the limit block to extend horizontally into the second limit opening, and the limit block is limited in the second limit opening to fix the filter press plate."

[0004] Although the equipment can limit the support seats on both sides of the filter press plate through the limit blocks, the position of the filter press plate can be fixed to avoid the problem of position displacement of the filter press plate, but the equipment is not equipped with an automatic unloading mechanism, resulting in manual operation or the use of simple mechanical devices to move the material after filtration. This method is not only cumbersome and inefficient, but also easily causes excessive physical burden on operators and increases labor intensity. At the same time, since dyes often have corrosive and toxic properties, long-term contact or inhalation poses a potential threat to human health. Therefore, manual unloading also has certain safety risks. Utility Model Content
