PP cotton filter element recycling treatment system

Abstract

The invention relates to a PP cotton filter element recycling treatment system. The system comprises a unwinding device; a first-stage cleaning device is fixedly mounted at the right end of the unwinding device and located on the ground; a second-stage cleaning device is fixedly arranged at the right end of the first-stage cleaning device and located on the ground; a winding device is fixedly arranged at the right end of the second-stage cleaning device and located on the ground; cleaning wheels which are located on the upper surface and the lower surface of the cotton filter element and can rotate are arranged between the winding and unwinding devices. The cleaning wheels and the surface of the unfolded cotton filter element rotate in opposite directions; therefore, a hairbrush rotates and moves; due to reverse rotation, the relative speed between the cotton filter element and the cleaning wheels is higher, flock-shaped filtering objects on the surface of the cotton filter element canbe better cleaned, the positions of the two cleaning wheels are staggered and installed up and down, and therefore the unfolded cotton filter element can be tightened through the positions of the twocleaning wheels, and a better cleaning effect is achieved.

Description

technical field [0001] The invention relates to the technical field of recycling PP cotton filter elements, in particular to a recovery and reuse treatment system for PP cotton filter elements. Background technique [0002] PP cotton filter element, also known as melt-blown PP filter element, is a filling filter element made of non-toxic and odorless polyester fiber particles, which are heated and melted, sprayed, drawn, and formed. It is not only used in large quantities in the field of water purification, but also It also has outstanding chemical compatibility and is suitable for the filtration of strong acids, strong alkalis and organic solvents. Its ability to hold dirt is very strong, and it is also widely used in various fields. Therefore, in order to further reduce production costs, it is usually necessary to filter PP with a high degree of pollution. Surface filter elements are recycled and reused, but there are some problems in the use of existing recycling equipmen...

Problems solved by technology

[0003] 1. The traditional cleaning method is to unwind and unwind the cotton filter element through the retracting and unwinding devices on both sides, and the unfolded surface filter element is cleaned by simply fixing the brushes installed on the upper and lower sides of it. Since the brush is The fixed and upper and lower pair of brushes are in a straight line in the vertical direction, so that the expanded filter element can only be squeezed by the brush to achieve better cleaning effect, but in this way, because the filter element is not in a tight state, Therefore, a good surface cleaning effect cannot be achieved at all, so that the recovery and cleaning of the PP cotton filter element cannot be well realized, and it cannot be reused well.

[0004] 2. Due to the wide range of applications of PP cotton filter elements, in some fields, after long-term use, there will be not only velvet-like filtrates accumulated on the surface, but also scale-like filtrates accumulated on it for a long time. The velvet-like filter is cleaned by a brush, but these scale-like filters cannot be cleaned by a brush. Generally, the chemical solvent reacts to soften and loosen the scale-like filter, and then clean it again. Or it is to carry out continuous flushing through the impact of high-speed water flow. If chemical solvents are used, not only will the cost of recycling be increased, but also because the reaction of chemical solvents takes a certain amount of time, this will also increase the time used for recycling. Restarting again is extremely inefficient, and if the water impact method is used, a large amount of water will be wasted, and there is no guarantee that the scale-like filter on it can be cleaned up, and the cleaning effect is not ideal.
