Unlike example 1, the enzyme preparation slurry filter of this example further includes an air distributor 8. The air distributor 8 is vertically installed on the inner wall of the lower cylinder 2 below the screen 4. The screen 4 performs filtration using the structure of fig. 8.

As shown in fig. 8, the filter belt 42 of the screen is further distributed with supporting bands 43 in a cross form, the supporting bands 43 are connected with the filter belt 42 and the fixing band 41 and divide the filter belt 42 into four fan-shaped filter screens, the supporting bands 43 are of a smooth surface structure with a concave center, the supporting bands 43, the filter belt 42 and the fixing band 41 are integrally formed, and the cross section of the smooth surface structure with the concave center is in a minor arc shape with a radian of 3-5 degrees.

Firstly, drawing a circle on a stainless steel sheet with the thickness of 0.25-0.3cm, cutting the circle according to the annular outer diameter of a second upper connector of the cylinder below the diameter of the circle, symmetrically arranging positioning grooves 10 on the edge of the circle, wherein the shape of the positioning grooves is rectangular, the width of the groove opening is 2-3cm, and the depth of the groove opening is 1-2cm, so as to form a circular blank; secondly, drawing an inner circle line by taking the circle center of the circular blank as the center and taking the inner diameter of the filter cylinder as the standard, punching the circular blank in the inner circle line through a cross die to form a blank of a circular flat screen with the circle center as the center and a downward sunken structure (namely a supporting belt) on the upper end surface, thirdly, manufacturing the flat screen, and forming meshes on the plane except the supporting belt in the inner circle line on the blank to prepare the flat screen. For example, when the outer diameter of the filter cylinder is 0.5m and the wall thickness of the cylinder is 1cm, the annular width of the second port is 5cm, the diameter of the blank is 55cm, the length of the support band is 46-48cm, then a circle with the diameter of 46-48cm is drawn on the upper end face of the blank by the center of the blank, the length of the cross support band is 46-48cm, the width of the cross support band is 0.5cm, and sieve holes, such as 20-50 mesh holes, preferably 30 mesh holes, are formed on the support band face except the circle, so that the cross support band screen is prepared.

The support belt 43 not only provides the skeleton support for the screen, improves the filtering strength and impact resistance of the screen, and can prolong the service life of the screen, but also provides a channel for collecting and transferring filter residues by the structure of the inferior arc depression of the support belt 43, and is convenient for deslagging under stirring.

As shown in fig. 9, the air distributor 8 is in a spoke shape, and includes a distribution disc 81 and a distribution strip 82, the distribution disc 81 and the distribution strip 82 are both in a tubular structure with their interiors interconnected, in this embodiment, a cross-shaped spoke is used, and other spoke-shaped designs can be used according to production needs. The distribution disc 81 and the distribution strips 82 are provided with a plurality of distribution holes 83 with the diameter of 2-3mm, the air distributor 8 is hermetically connected with a high-pressure air pipeline 84 outside the cylinder body, and the distribution holes 83 are one-way holes with pore plates and are arranged towards the direction of the screen 4. When the vertical stirring device 13 is not installed, the air distributor 8 is installed 2 to 5cm above the screen 4, and the distribution holes 83 are opened in the upward direction, the inner wall direction of the cylinder, the central axis of the cylinder, or the downward direction. The high-pressure air pipeline 84 is opened periodically, high-pressure air coming out of the distribution holes 83 opened towards the direction of the screen 4 can not only blow away filter residues deposited on the screen 4, especially when an inferior arc-shaped concave structure of the support belt 43 exists, the high-pressure air flow can guide the filter residues in the concave and adjacent filter residues to be transferred to the first residue discharge port on the inner wall of the cylinder body, so that the mesh of the screen is dredged, the filter residues are separated, and the filtering effect is improved, the high-pressure air coming out of the distribution holes 83 opened towards other directions can play a role in stirring slurry by air, and the high-pressure air can also prevent the filter residues from accumulating in pipelines of the distribution disc and the distribution strips.

The working process of the enzyme preparation slurry filter is as follows: slurry enters the upper barrel 1 of the filter from the feeding pipe 15 through the feeding hole 14, filter residues are filtered through the screen 4 under stirring, and filtrate enters the lower barrel 2 and flows out through the discharging hole 20 and the discharging pipe 21 to enter a lower-stage drying procedure. Most of filter residues are discharged from the barrel body through the first residue discharge port 24 and the first residue discharge pipe 25, and the filter residues mixed in the lower barrel body 2 are accumulated at the position of an inverted cone in the center of the bottom of the lower barrel body 2 after the slurry is settled by the slurry, and are discharged through the second residue discharge port 27 and the second residue discharge pipe 28. The air distributor can play a role in stirring slurry, dredge meshes of the screen and accelerate the transfer of filter residue and slag discharge. Because the slurry is discharged without shutdown, the production efficiency is greatly improved, the maintenance period is adjusted from shutdown for slag discharge and maintenance every shift every day to shutdown for slag discharge and maintenance once every month, and the service life of the screen is also greatly prolonged.
