A screen plate is installed inside the main body near the top. A cleaning mechanism is movably installed at the bottom of the screen plate. A drive mechanism is installed at the drive end of the cleaning mechanism. A moving mechanism is installed at the connection between the drive mechanism and the cleaning mechanism. However, in the case of existing screening devices, a filter screen is installed inside the device. Because the filter screen is inside the device, it is inconvenient to remove the filter screen. Furthermore, it is not convenient to observe the internal condition of the pulp screening device after the device has been used for a long time. Utility Model Content

[0012] 1. In this utility model, the arrangement of the flange partition, bolts and filter screen facilitates the use of the filter screen for three-stage filtration and makes it easy to remove the filter screen from the water tank for maintenance or replacement.
[0013] 2. In this utility model, the setting of the observation window and the glass window is beneficial for observing the solidified solids on the surface after a long period of filtration, and for preventing the filter screen from becoming clogged due to prolonged observation through the observation window and the glass window.
[0014] 3. In this utility model, the flange partition, blade and filter screen are conducive to moving the filter screen, and the large solidified pulp on the surface is treated at the same time as the filter screen is removed. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings, as shown below. Figure 1 As shown, an improved paper pulp screening device includes a water tank 1, a funnel 2 threadedly connected to the upper part of the water tank 1, an observation window 3 embedded in the center of the water tank 1, a multi-functional filter 4 installed on the left side of the water tank 1, a water pump 6 fixedly installed on the upper part of the base 5, a water outlet pipe 7 threadedly connected to the water outlet end of the water pump 6, and the water inlet of the water pump 6 connected to an opening pipe opened on the lower side of the water tank 1.
[0020] This implementation plan, as shown in the appendix Figure 2As shown, the multifunctional filter 4 includes a flange partition 41, bolts 43 and fixing plates 46. The left side of the water tank 1 is sealed with the flange partition 41 by bolts 43. A handle 42 is welded to the left side of the flange partition 41. Filter screens 47 are welded to the right side of the flange partition 41 from top to bottom. One end of each of the multiple filter screens 47 is placed on the upper part of the multiple fixing plates 46.
[0021] In this embodiment, specifically, multiple fixing plates 46 are screwed together from top to bottom to the inner right side of the water tank 1.
[0022] In this embodiment, specifically, blades 44 are fixedly installed on the left inner wall of water tank 1 from top to bottom. The blades 44 are configured to cooperate with the filter screen 47, and the lower end of the blades 44 is in contact with the upper part of the filter screen 47.
[0023] In this embodiment, specifically, the right side of the water tank 1 is sealed with glass windows 45 from top to bottom.

[0026] In this embodiment, specifically, the blade 44 is made of stainless steel.
[0027] In this embodiment, specifically, the plurality of filter screens 47 are respectively set as steel filter screens with pore sizes decreasing from top to bottom to achieve different filtration effects.
[0028] Working principle
[0029] In this invention, paper pulp is poured into funnel 2, and the filtration of the paper pulp is observed through observation window 3. The pulp is filtered three times through filter screen 47 to remove impurities and agglomerated lumps of solids, thereby achieving the filtration effect. Water pump 6 is connected to an external power source and started. The input end of water pump 6 draws in paper pulp, and the output end transports the paper pulp to another industrial device. After a long period of filtration, solids or intercepted paper lumps will solidify on the surface of filter screen 47. The degree of blockage of filter screen 47 is observed through observation window 3 and glass window 45. When filter screen 47 needs to be cleaned, bolt 43 is removed to remove flange partition 41. Moving flange partition 41 moves filter screen 47. At the same time as filter screen 47 is removed, the blade 44 scrapes off the large solidified pulp on the surface of filter screen 47, thus cleaning filter screen 47.
[0030] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution of this utility model, falls within the protection scope of this utility model.
