The continuous cake beating device and the continuous cake beating method of example 1 were adopted, except that in the cake beating device, the included angle between the length direction of each blade or baffle and the radial direction of the inner cylinder 2 was 40 degrees in the direction of the material flow.
Test example
The average particle diameter of the slurry discharged from the filter at the material outlet 5 on the side wall of the housing in examples 1 to 5 was measured. The determination method is a laser particle size method, and the determination results are shown in the following table 1.
TABLE 1
The filter cake beating device with the specific structure can be used for continuously beating filter cakes of various properties and types, can obviously improve the effect and efficiency of beating the filter cakes, and ensures that the particle size of particles in slurry discharged from the shell is less than or equal to 10 micrometers (for example, the particle size can be 1-10 micrometers), so that the subsequent application of the slurry can be more favorably realized, for example, in the field of catalysts and molecular sieves, the slurry with smaller and uniform particle size is more favorably washed by water to remove impurity ions in the catalysts, and the products such as the catalysts, the molecular sieves and the like with higher purity can be more favorably obtained.
Comparing examples 1-3 with example 4, it can be seen that when the rotation conditions of the housing 1 and the inner cylinder 2 include: when the direction of rotation of the shell 1 and the inner cylinder 2 is opposite, the crushing and the pulping of the filter cake are more facilitated.

Therefore, the filter cake pulping device with the specific structure can realize continuous pulping of the filter cake and can obviously improve the effect and efficiency of the filter cake pulping. Specifically, after the filter cake and water enter the inner barrel, the inner barrel is driven by a driving device to rotate at a high speed, the filter cake is crushed under the action of the shearing force and the centrifugal force of the water and a blade or a baffle plate arranged on the inner wall of the inner barrel, then the slurry enters an accommodating cavity between the inner barrel and the shell through a sieve hole on the inner barrel, the shell rotates to mix and crush the slurry again, and then the slurry is discharged from the lateral line of the shell through a filter at a material outlet. The pulping device has simple manufacturing process, can efficiently and continuously form slurry, and has short pulping time; meanwhile, the cleaning device has the effects of practicability, safety and convenience in cleaning. The problems that a discharge port is blocked and the bottom of a pulping tank is easy to settle due to overlarge particle diameter caused by limited effect of crushing a filter cake by a pulping paddle are solved. Therefore, the pulping device is completely different from the traditional vertical pulping and crushing system, can completely crush and stir the filter cake without adopting a stirring paddle, is mainly dependent on comprehensive acting force such as centrifugal force, mechanical force, shearing force and the like to continuously form pulp, has short pulping time and high efficiency, and can be continuously operated.
