Description

Technical Field

[0001] This utility model relates to the field of ink technology, specifically to an ink storage container that prevents sedimentation. Background Technology

[0002] In industries such as printing and packaging, ink is an important printing material. During storage, it often contains solid components such as pigments and fillers, which can lead to sedimentation and stratification when stored for a long time. This can result in uneven ink performance, affecting printing quality and production efficiency.

[0003] Existing storage tanks use a single stirring method. The central shaft stirring can only generate axial flow, and the radial flow is insufficient. As a result, the ink on the tank wall and bottom is difficult to mix fully, creating a stirring blind zone that easily leads to ink sedimentation. Utility Model Content

[0004] The purpose of this invention is to provide an ink storage tank that prevents sedimentation. Through the cooperation of a stirring assembly, an electric push rod, and a filter screen, the driver of the stirring assembly drives the scraper and spiral blades to stir the ink. At the same time, the electric push rod drives the filter screen to move up and down within a set range, so that the filter screen carries the ink to form vertical convection. Combined with the horizontal stirring of the stirring assembly, a three-dimensional mixing flow field is formed in the tank, which effectively disturbs the ink, keeps the ink particles in a suspended state, reduces sedimentation and accumulation at the bottom and inner wall of the tank, and improves the anti-sedimentation effect.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to an ink storage tank for preventing sedimentation, comprising a tank body, a conical bottom tank connected to the bottom of the tank body, a discharge pipe connected to the bottom of the conical bottom tank, support legs welded to the outer wall of the tank body, a tank cover connected to the top of the tank body by bolts, a stirring assembly installed on the tank cover, the stirring assembly including a driver, a drive rod installed at the bottom of the driver, a scraper fixedly connected to the drive rod, a spiral blade provided at the bottom of the drive rod, a filter screen overlapping the side wall of the bottom of the tank body, and an electric push rod installed at each of the four corners of the top surface of the filter screen.

[0007] Furthermore, the tank body is a rectangular tank with openings at both the top and bottom, and the conical bottom tank is a bucket shape with an opening at the top. The top opening of the conical bottom tank is welded and connected to the bottom opening of the tank body. A discharge hole is opened at the bottom of the conical bottom tank, and the top of the discharge pipe is welded to the discharge hole.

[0008] Furthermore, the bottom surface of the can lid is abutted against the opening at the top of the can body. Threaded holes are opened at the contact ends of the can body and the can lid. Bolts are sequentially threaded through and connected to the threaded holes on the can body and the can lid. An installation hole is opened through the middle of the can lid. A coupling is provided at the bottom of the driver. The coupling extends through the installation hole and is located below the can lid.

[0009] Furthermore, the stirring assembly consists of two "D"-shaped rods, with the hooks of the two "D"-shaped rods arranged in a cross shape. The outer sides of the two "D"-shaped rods abut against the inner wall of the tank. The bottom end of the drive rod extends through the intersection of the bottom ends of the two "D"-shaped rods and is threadedly connected to the spiral blade below the scraper.

[0010] Furthermore, the filter screen is tapered, wider at the top and narrower at the bottom, and its shape matches the cross-sectional shape of the inner wall of the tapered bottom tank. The filter screen is connected to the tank body by an electric push rod, and the tops of the four filter screens are respectively installed at the four corners of the inner wall of the tank by bolts. The spiral blades are located inside the filter screen.

[0011] This utility model has the following beneficial effects:

[0012] This invention utilizes a stirring assembly, an electric push rod, and a filter screen. The stirring assembly's driver drives the scraper and spiral blades to stir the ink, while the electric push rod moves the filter screen up and down within a set range. This causes the filter screen to carry the ink in a vertical convection, which, combined with the horizontal stirring of the stirring assembly, creates a three-dimensional mixing flow field within the tank. This effectively agitates the ink and maintains a safe distance from the spiral blades during movement to avoid collisions, keeping the ink particles in suspension and reducing sediment buildup at the bottom and inner walls of the tank, thus improving the anti-settling effect.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The bottom of the filter 603 extends from the intersection of the two "D"-shaped rods and is threadedly connected to the spiral blade 604 below the scraper 603. A filter screen 8 is attached to the bottom side wall of the tank 1. A retaining block is provided at the bottom of the inner wall of the tank 1. The bottom surface of the filter screen 8 overlaps the top surface of the retaining block. The filter screen 8 is made of 316L stainless steel. The specific type can be selected according to the particle size distribution of the pigment particles in the ink. For fine-particle inks, a small-aperture model is suitable for precise interception, while for coarse-particle inks, a large-aperture model can be selected to ensure flow efficiency, balancing filtration effect and ink flow. Electric push rods 7 are installed at the four corners of the top surface of the filter screen 8. The electric push rods 7 can be of the ATG-SV series and have a built-in encoder.
