Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dispersion filtration technology, specifically relating to a high-efficiency filtration device. Background Technology
[0002] Existing printing paper coating technology requires the use of dispersion liquid, which needs to be added quantitatively through filtration. Current printing uses ton drums to store the dispersion liquid for 4-5 days to settle, and then uses a centrifugal pump for filtration. This requires frequent filling of the ton drum to determine the dosage and then allowing it to settle again, which is cumbersome, time-consuming, and labor-intensive. In addition, the filtration device is prone to clogging and is inefficient. Utility Model Content

The 10-ton settling tank, the pneumatic diaphragm pump, the filter, and the mixing tank are connected in sequence through pipelines. The mixing tank is equipped with a weighing module. The filter is provided with a top cover, an inlet on the top cover, and an outlet at the bottom. The filter is provided with a double-layer filter screen inside.
[0005] The double-layer filter screen includes a filter mesh and a stainless steel filter screen. The filter mesh is connected to the top cover, and the stainless steel filter screen is fixed to the inner wall of the filter and located below the filter mesh.
[0006] The filter mesh has a conical filter surface with multiple sets of baffles.
[0007] Each set of baffles includes at least two barbed needles at a 45° angle to the water-facing surface of the filter mesh, and the length of the barbed needles does not exceed three times the thickness of the filter mesh.
[0008] The filter mesh is fixed to the top cover by pull rods. There are two pull rods, which are symmetrically arranged on both sides of the liquid inlet.
[0009] The filter is U-shaped, and a buffer layer is provided at the bottom of the filter cavity.
[0010] The high-efficiency filtration device provided by this utility model has the following advantages: the filter has a double-layer filter screen inside, which has a good filtration effect. The filter screen has a conical filter surface, which increases the filtration area and improves work efficiency. After use, it can effectively improve the labor efficiency of employees. The improvement of the metering method can improve the metering accuracy, eliminating the need for multiple batches of ton containers for pre-metering and settling. It saves 50% of workshop space, 40% of equipment wear and tear, reduces the error rate, and improves the efficiency of workshop employees. Attached Figure Description

[0013] The high-efficiency filtration device provided by this utility model will now be described in detail with reference to the accompanying drawings and an embodiment.
[0014] Example Reference Figures 1-2 The high-efficiency filtration device of this embodiment includes a mixing tank 2, a filter 3, a pneumatic diaphragm pump 6, and a 10-ton settling tank 5. The 10-ton settling tank 5, the pneumatic diaphragm pump 6, the filter 3, and the mixing tank 2 are connected in sequence through a pipeline 4. The mixing tank 2 is equipped with a weighing module 1. The filter 3 is provided with a top cover 7, an inlet 8 on the top cover 7, and an outlet 13 at the bottom of the filter 3. The filter 3 is provided with a double-layer filter screen inside.

[0016] The filter surface of the filter mesh 10 is conical, and multiple sets of baffles 11 are provided on the filter surface to quickly filter out impurities.
[0017] Each set of baffle pins 11 includes at least two barbed pins at a 45° angle to the water-facing surface of the filter mesh, and the length of the barbed pins does not exceed three times the thickness of the filter mesh.
[0018] The filter mesh 10 is fixed to the top cover 7 by a pull rod 9. There are two pull rods 9, which are symmetrically arranged on both sides of the liquid inlet.
[0019] The filter is U-shaped, and a buffer layer 14 is provided at the bottom of the filter cavity.
[0020] Reference Figure 3 The weighing module is an integrated electronic weighing and measuring element that combines a weighing sensor, a load transfer device, and mounting connectors. It consists of an outer protective shell 1-1, a fixed connecting plate 1-2, an upper bearing plate 1-3, an upper connector 1-4, a weighing sensor 1-5, a load support column 1-6, a lower connector 1-7, a base plate 1-8, and support bolts.

[0021] The weighing module is connected to and controlled by a weighing controller. The pneumatic diaphragm pump is connected to and controlled by a pneumatic valve controller. The pneumatic valve controller controls the pneumatic diaphragm pump to filter the settled dispersion in the 10-ton settling tank through a filter into the mixing vessel. The weighing module is added to the mixing vessel to measure the filtered dispersion. Once the set weight is reached, the pneumatic diaphragm pump automatically stops supplying air. The weighing module measures the filtered dispersion accurately, eliminating the need for batch measurement in the 10-ton settling tank. It is convenient to use, and the double-layer filter provides good filtration effect and high efficiency.
