Separation device and method for spherical particles and broken particles

Abstract

The invention relates to a separation device and method for spherical particles and broken particles. The separation device comprises a storage hopper, a direction changing acceleration pipe, an inclined separation plate, a horizontal buffer plate and a collection tank, an included angle between the inclined separation plate and the horizontal buffer plate is adjusted through an electric push rod,so that the spherical particles in ion exchange resin can roll down along the inclined separation plate and the horizontal buffer plate and finally enter the collection tank, the broken particles cannot roll down from the inclined separation plate, the spherical particles and the broken particles are separated through circulating separation for many times, after an experiment is finished, brokenresin is scraped from the inclined separation plate into the horizontal buffer plate through a scraper, and finally the broken resin is taken out in a centralized mode through the collection tank. According to the device and the method, the time and labor investment for separating the spherical particles from the broken particles can be greatly saved, the separation effect is good, meanwhile, equipment is simple, the cost is low, the practicability is high, and brand-new operation equipment and an experimental method are provided for measuring the spherical ratio of the ion exchange resin in alaboratory.

Description

technical field [0001] The invention relates to the technical field of resin separation equipment, in particular to a separation device and method for spherical particles and crushed particles. Background technique [0002] Ion exchange resin is a kind of polymer compound with a network structure with active groups. It is widely used in the softening treatment of circulating cooling water make-up water in thermal power plants, the desalination treatment of boiler make-up water, and the fine treatment of condensed water in steam systems. Therefore, the performance index of ion exchange resin directly affects the normal operation of the water treatment system. The performance index of ion exchange resin mainly includes particle size, density, water content, swelling and transformation volume change rate, exchange capacity, and mechanical strength. [0003] Among them, the mechanical strength of the resin refers to the ability of the resin to resist damage under the action of v...

Problems solved by technology

[0004] At present, the method of separating the spherical particles of the resin from the broken particles is mainly manual separation. The manual separation method is to place the resin sample on the upper left corner of the enamel plate, raise the upper edge of the enamel plate, and place the enamel plate obliquely. The inclination angle can make the The balls roll down under gentle vibration while the broken particles cannot roll down. Gently stir a small part of the resin with a brush to separate the ball particles from the broken particles, and brush the broken particles to the upper right corner of the enamel plate. Until all the samples are separated, the disadvantages are time-consuming and labor-intensive, and the brush will be stained with resin, resulting in inaccurate measurement
