Embodiment

[0024] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a pulping equipment of the present invention with material-liquid separation and secondary air vortex crushing mainly includes a feeding device, a vortex crushing device, and a slurry generating device.

[0025]The feeding device is mainly composed of a feeding port 19, a spring 15, a spring protective cover 16 and a buffer and a sealing plate 18. The feeding port 19 is opened on the top cover 14, and the upper and lower ends of the spring 15 are respectively connected to the top cover 14 and the buffering and sealing plate. The sealing plate 18 is covered with a spring protective cover 16 on the outside of the spring 15, and the top cover 14, the buffer and sealing plate 18 and the upper part of the inner cone 11 enclose the feeding buffer zone 17.

[0026] The buffer and sealing plate 18 is a disc-shaped structure with a certain slope, which can realize the blanking slowly entering the primary vortex c...

Abstract

The invention provides a pulping device capable of achieving solid-liquid separation and secondary air vortex breakdown. The pulping device mainly comprises a feeding device, a vortex breakdown device and a liquid pulp generating device and is characterized in that solid and liquid are separated, air vortex breakdown is conducted firstly, and then broken materials are mixed with liquid water to form pulp. According to the pulping device, feeding amount control and sealing are achieved through a buffering and sealing plate and a spring, tangential feeding of air is achieved and loop current is formed through an air inlet tangent to the outer edge of the bottom of an inner conical cylinder, rotational flow is accelerated twice through a tapered primary vortex breakdown area and an oblique secondary vortex breakdown area, the broken materials are screened twice and blockage prevention is achieved through circular truncated cone-shaped holes in a primary filtering device and a secondary filtering device, and mixing and stirring of solid and liquid are achieved through a broken material delivery pipe.

Description

technical field [0001] The invention relates to a kind of pulping equipment with material-liquid separation and secondary air vortex crushing, in particular to a kind of control and sealing of the feeding amount through a buffer and sealing plate and a spring, and through contact with the outer edge of the bottom of the inner cone The cut air inlet realizes the tangential entry of gas and forms a circulation, and realizes the double acceleration of the swirling flow through the primary vortex crushing area with a certain taper and the secondary vortex crushing area with a certain slope, and through the primary and secondary filtration The circular platform hole in the device realizes the secondary screening and anti-blocking of the crushed material, and realizes the mixing and stirring of material and liquid through the crushed material conveying pipe, which belongs to the technical research and development field of pulping equipment in the papermaking industry.
