Rubber antioxidant product grading device and grading method

Abstract

The invention discloses a rubber antioxidant product grading device and a grading method. The device comprises a tiltable platform, a rotatable roller is arranged on the tiltable platform, and a plurality of layers of cuboid sieves which are mutually nested together are sequentially arranged in the roller. In addition, the invention further discloses the grading method of the device. According to the rubber antioxidant product grading device and the grading method, the quantity of rubber antioxidant products in contact with screen holes in unit time can be increased, and the screening and grading efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of rubber anti-aging agent production, in particular to a rubber anti-aging agent product grading device and a grading method. Background technique [0002] After the rubber anti-aging agent is produced, it is necessary to classify products of different sizes. At present, there are two commonly used methods: the first is to classify and screen directly through multiple flat screens or sieve plates. The problems with this device Yes, the contact surface between the product and the sieve or sieve plate is one side each time, the amount of product that touches the sieve hole per unit time is small, the screening speed is slow, and each layer of sieve or sieve plate needs to be manually removed when discharging. Take it away, and then unload the product; the second is to screen and classify through the rotating screen drum. This device generally adds a spiral track on the inner wall of the rotating screen drum. ...

Problems solved by technology

[0002]After the production of rubber antioxidants is completed, products of different specifications need to be graded. Currently, there are two commonly used methods: the first is to pass through multiple planes directly The screen or sieve plate is used for grading and screening. The problem with this device is that each time the contact surface between the product and the screen or sieve plate is one side, the amount of product that touches the sieve hole per unit time is small, and the screening speed is slow. Moreover, it is necessary to manually remove each layer of screen or sieve plate when discharging, and then unload the product; the second is to screen and classify through the rotating screen drum. This device generally adds a spiral track to the inner wall of the rotating screen drum, and then With the rotation of the rotary screen cylinder, the material can be screened while moving. The problem with this device is that the material moves very slowly in the rotary screen cylinder, and the material can only touch one side of the screen hole at all times. The amount of product that touches the sieve holes is also small, and the screening efficiency is low
