Description

Technical Field

[0001] The utility model relates to the technical field of surface treatment agent production, in particular to a filter press for leather surface treatment agent production. Background Art

[0002] Artificial leather is a kind of artificial leather produced by polyurethane (PU) resin and non-woven fabric as raw materials. It is currently mainly used as raw material for shoes, bags, balls, clothing, etc. It has been widely used because of its similar leather effect and good processing performance. Surface treatment agents are often used in the post-processing of artificial leather. The post-processing of synthetic leather, such as embossing, grinding, printing, spraying, rubbing, etc., can give synthetic leather special effects, make synthetic leather products diversified, and improve the added value of synthetic leather products.

[0003] In the prior art, such as Chinese patent CN213761793U, a filter press for producing a surface treatment agent includes a reactor, a filter press and a stirrer. The production device is provided with a stirrer and an electric heater to heat and stir the treatment agent, and a temperature control box is installed to regulate the temperature, thereby avoiding excessively high or low temperatures and improving the reaction speed of the raw materials. Multiple groups of stirring blades are installed to drive the upper and lower treatment agents to mix together, heat evenly, and improve work efficiency. A filter box is provided at the bottom of the reactor to perform preliminary filtration on the treatment agent, and the filtered treatment agent enters the filter press chamber through a pipeline. The pressure plate is driven horizontally by the installed hydraulic cylinder to separate the solid and liquid. Multiple groups of filter cloths are installed to filter the surface treatment agent first and then squeeze it. The structure is simple, and the filter holes on the filter plate are not easy to be blocked. The processed surface treatment agent flows out through the liquid outlet for use.

[0004] In the above patent, a filter box is arranged at the bottom of the reactor to perform preliminary filtration on the treatment agent, and the filtered treatment agent enters the filter press chamber through a pipeline, and the pressure plate is driven horizontally by the installed hydraulic cylinder to separate the solid and liquid. However, during the filtration process, the filter block on one side can only be squeezed by the push rod. This will cause the material pressure close to the push rod side to be greater than the pressure on the original push rod side when the material is pressed. The pressure cannot be evenly distributed on the surface of the material, and the extrusion force cannot act evenly on the material, resulting in low filtration efficiency. Therefore, it is necessary to propose a new type of filter press for the production of leather surface treatment agents. Utility Model Content
