[0017] Figure 1 , 2As shown in the figure, a collagen filtering device includes a motor speed reduction mechanism 1, a centrifugal cylinder 2, a shunt cylinder 3, valves, a rack 5, a filter screen 6, a bottom plate 7, a fixed plate 8, and a spiral stirring blade 9. A hollow support seat 21 is welded to the inner upper end of the centrifugal cylinder 2. An inlet hole 22 and a filter hole 23 are respectively arranged at the upper front side and the right middle part of the centrifugal cylinder 2. An inlet pipe 24 is welded to the outer side of the inlet hole. The outer side of the inlet pipe 24 and a first end of a three-way pipe 25 are threadedly connected. There are five valves. The other two ends of the three-way pipe 25 are respectively connected to one end of a first valve 41 and one end of a second valve 42 through pipe joints. A clear liquid pipe 231 is welded to the outer side of the filter hole. A third valve 43 is threadedly connected to the lower end of the clear liquid pipe 231. A hollow support ring 61 is welded to the lower end of the filter screen 6. The support ring 61 of the filter screen is sleeved on the support seat 21. The rack 5 has three sets. The upper ends of the three sets of racks 5 are respectively welded to the outer side of the upper end of the centrifugal cylinder 2. The lower ends of the three sets of racks 5 are respectively welded to the upper middle part of the bottom plate 7. A lower annular hollow flange 26 (with multiple fixing holes) is welded to the outer side of the upper end of the centrifugal cylinder. The fixed plate 8 has multiple fixing holes around it. The fixed plate 8 is sealingly installed with the lower flange 26 through bolts (the bolt connection mode can facilitate the removal of the fixed plate 8 for maintenance of the motor speed reduction mechanism, etc.). The fixed plate 8 has an opening in the middle part. An axle sleeve pipe 81 is vertically welded to the outer side of the lower end of the opening of the fixed plate 8. An inner upper end and an inner lower end of the axle sleeve pipe 81 are respectively tightly sleeved with a bearing (not shown in the figure). The motor speed reduction mechanism 1 is fixedly installed on the fixed plate 8, and the rotating shaft of the motor speed reduction mechanism 1 is tightly sleeved in the inner ring of the two bearings. An agitator rod 10 is welded to the lower end of the rotating shaft. The spiral stirring blade 9 is welded to the outer side end of the agitator rod 10. The lower end of the centrifugal cylinder 2 is threadedly connected to the upper end of a fourth valve 44. The upper end of the shunt cylinder 3 is threadedly connected to the lower end of the fourth valve 44. The lower end of the shunt cylinder 3 is threadedly connected to the upper end of a fifth valve 45. The lower end of the fifth valve 45 is threadedly connected to an outlet pipe 11.

[0018] Figure 1 、 2As shown, the other end of the clear liquid pipe 231 and the liquid inlet pipe of the low-positioned collagen tank are connected by a pipeline, the other end of the first valve 41 and the second valve 42 and the liquid outlet pipe of the low-positioned raw material tank, the purified water pipe are respectively connected by a pipeline. The outer diameter of the support ring 61 is slightly smaller than the outer diameter of the filter screen 6, and the outer side of the filter screen 6 and the inner side of the centrifugal cylinder 2 are in an interference fit structure. The filter screen 6 is in a ring-shaped vertical state (when working, the liquid is tangentially introduced into the device and rotates in the same direction as the motor, generating a cyclone, and the cyclone drives the solid impurities to move downward. The relatively coarse solids are not easy to block the filter screen through downward cyclone scouring and gravity settling). The outer diameter of the upper end of the centrifugal cylinder 2 and the flow distribution cylinder 3 is larger than the outer diameter of the lower end, and is a conical structure. The valve is one of a hand valve and an electromagnetic valve. The front side end of the flow distribution cylinder has an opening, and the opening side end is provided with a transparent glass observation plate 27 installed through an annular hollow sealing plate (the staff can observe the particle deposition in the flow distribution cylinder 2, and if necessary, open the valve 45 to discharge the particles).

[0019] Figure 1 、 2As shown, when this new type of equipment is in operation, valve 41 of the liquid outlet pipe at the lower end of the raw material tank is opened. In this way, the raw material in the raw material tank will enter the centrifuge cylinder 2 tangentially through the liquid inlet pipe (at the same time, the power switch of the motor reduction mechanism 1 is turned on, and the motor reduction mechanism 1 drives the stirring blade 9 to rotate). The liquid enters the centrifuge cylinder 2 through the feed port and generates a swirling flow under the drive of the motor reduction mechanism 1 (the collagen protein hydrolysate has a certain viscosity. When the flow rate and pressure from the feed port are insufficient, the stirring action of the spiral blade 9 under the motor reduction mechanism can increase the swirling speed of the liquid and force the liquid entering through valve 41 to flow downward). The solid particles in the material move downward in a rotary motion under the constraint of the cylindrical wall of the centrifuge cylinder 2. Specifically, the collagen hydrolysate enters the centrifuge cylinder 2 through the inlet pipe and flows tangentially along its wall. Part of the hydrolysate rotates along the spiral path of the rotating blades 9 towards the bottom of the centrifuge cylinder 2 and is discharged. The remaining hydrolysate, reaching the bottom, is carried by the liquid flowing towards the center and filtered through the filter screen 6. It then flows out through the clear liquid pipe 231, overflowing into the finished collagen tank to obtain the filtered collagen product. Larger solid impurities in the hydrolysate are gradually thrown towards the inner wall of the centrifuge cylinder by centrifugal force, falling along the inner wall and sliding towards the bottom outlet of the centrifuge cylinder 2. The upward overflow has a reduced solids content and flows out through the clear liquid pipe via the filter screen 6, thus obtaining a hydrolysate with reduced solids content, completing the coarse filtration of the collagen hydrolysate. As described above, during operation, solid impurities are driven downwards by the swirling current and the helical impeller. The upper filter screen contains fewer solid impurities, and the swirling current and gravity settling action carry away adhering impurities, achieving automatic cleaning. This significantly reduces filter screen clogging and greatly improves filtration efficiency. Furthermore, the filtration precision can be adjusted by changing the filter screen mesh size and motor speed. When there is a large amount of solid sediment (fine particles) at the lower end of the diverter 3, valve 41 can be temporarily closed, followed by closing valve 44 and opening valve 45. This allows the mixed coarse particles in the separator 3 to be discharged into the waste liquid tank located below valve 45 (which can be filtered later to separate the collagen material from the mixed fine particles). After discharge, valve 44 and valve 41 are opened to continue filtration. After production is complete, valves 43 and 41 can be closed, and valves 42, 44, and 45 can be opened. This allows purified water to enter the centrifuge cylinder 2 and separator 3, cleaning the centrifuge cylinder 2, separator 3, valves, etc., ensuring optimal performance for future use. This new type of equipment brings convenience to staff, reduces the frequency of cleaning the filter, and improves work efficiency accordingly.
