Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a sludge filter press dehydrator for a food factory. Background Art

[0002] A dewatering filter press is a machine that uses the pressure of compressed air, water or an electric pump to filter and compact the sludge through the filter material to reduce the water content. Its main principle is to pressurize the sludge under the drive of the filter cloth or filter plate to release water and achieve the goal of dehydration. Dewatering filter presses can be divided into indoor, outdoor, filter presses with screw squeezers, filter presses with rolling squeezers and other types. Each type of filter press has its own characteristics.

[0003] After searching, the Chinese patent number CN217916911 U is a screening mechanism for a spiral extrusion dehydrator. The technical key points are that the utility model relates to the technical field of spiral extrusion dehydrators, and in particular to a screening mechanism for a spiral extrusion dehydrator, including an inner screen, an outer screen, and a support cage arranged in sequence from the inside to the outside; the inner screen and the outer screen are both cylindrical, and the outer wall of the inner screen fits the inner wall of the outer screen; the thickness of the outer screen is greater than the thickness of the inner screen; outer screen holes are arranged on the outer screen, and inner screen holes are arranged on the inner screen; the support cage is composed of two semi-support cages, each semi-support cage includes a plurality of support sheets arranged at intervals on the outside of the outer screen along the axial direction, a plurality of ribs fixedly connected to the outside of each support sheet, and connecting flanges fixedly connected to both ends of each rib. The screen is composed of an outer screen and an inner screen, which can withstand greater squeezing force. The screen is composed of two semi-cylindrical half screens connected together, which is convenient for replacement. The support cage can reinforce the screen from the outside to reduce the damage and deformation of the screen and extend the service life of the screen.

[0004] Although this technology solves the problem that the screen is subjected to internal pressure for a long time and is very easy to be damaged and deformed, the service life of the screen is not long and needs to be replaced frequently, but during the sludge filtration process produced by the food factory, the sludge contains sticky substances (such as honey syrup), which are easy to adhere to the screen. After long-term use, the mesh of the screen will become smaller and smaller, resulting in the water filtering effect of the equipment becoming worse and worse. When the filter is cleaned, the equipment needs to be shut down for maintenance, which leads to reduced work efficiency. Utility Model Content
