Description

Technical Field

[0001] This utility model relates to the field of pigment production technology, and in particular to a pigment production filtration device. Background Technology

[0002] During the pigment preparation process, the presence of even a small amount of iron can seriously affect the product quality, so it is necessary to remove these iron impurities.

[0003] In the application document CN201220449234.0, the liquid to be filtered is discharged from the outlet pipe after passing through the filter cylinder 2. The magnet 3 placed inside the filter cylinder 2 adsorbs the iron impurities in the liquid to be filtered, so that the impurity content of the filtered liquid is reduced and the quality of the pigment is improved. During the liquid introduction process, the small contact area between the magnet and the liquid results in a significant amount of liquid failing to come into contact with the magnet, and the short contact time between the magnet and the liquid reduces the adsorption effect on iron impurities in the liquid. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the small contact area between the magnet and the liquid, and the short contact time between the magnet and the liquid, which reduces the adsorption effect on iron impurities in the liquid. Therefore, this invention proposes a pigment production filtration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pigment production filtration device is designed, including a cylindrical body. A drain pipe is connected to the bottom of one side of the cylindrical body. A feed rack is inserted into the upper end of the cylindrical body. Both sides of the feed rack are connected to the cylindrical body through fixing mechanisms. A first fixing rod is fixedly connected to one side of the bottom end of the feed rack. A plurality of first magnet plates are connected at equal intervals along the length direction on the first fixing rod. A first gap opening is provided between one side of each first magnet plate and the inner wall of the cylindrical body. A second fixing rod is fixedly connected to the other side of the bottom end of the feed rack. A plurality of second magnet plates are connected at equal intervals along the length direction on the second fixing rod. A second gap opening is provided between one side of each second magnet plate and the inner wall of the cylindrical body.

[0006] Preferably, the fixing mechanism includes a threaded rod, one end of which is fixedly connected to the feed rack, a perforated plate is fixedly connected to the cylinder, and the other end of the threaded rod passes through the perforated plate and is fixedly connected to a fixing nut.

[0007] Preferably, a first limiting strip is fixedly connected to the upper end of the side of each first magnet plate near the first gap opening.

[0008] Preferably, a second limiting strip is fixedly connected to the upper end of the side of each second magnet plate near the second gap.

[0009] Preferably, the feed rack is connected to a cleaning mechanism, which includes a fixing ring fixedly connected to the feed rack. A filter screen is fixedly connected to the upper end of the fixing ring. A third fixing rod is fixedly connected to the inner ring wall of the fixing ring. A support rod is fixedly connected to the upper end of the third fixing rod, and the upper end of the support rod contacts the bottom end of the filter screen.

[0010] Preferably, the filter screen is a convex filter screen.

[0011] The pigment production filtration device proposed in this utility model has the following advantages: As the liquid flows downward, it continuously comes into contact with the first and second magnetic plates. The increased contact area between the first and second magnetic plates and the liquid, along with the buffering effect of the first and second limiting strips, prolongs the contact time between the first and second magnetic plates and the liquid, thereby improving the adsorption effect of the first and second magnetic plates on iron impurities in the liquid.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example 1: Refer to Figure 1-3A pigment production filtration device includes a cylinder 1. A drain pipe 2 is connected to the bottom of one side of the cylinder 1. A feed rack 3 is inserted into the upper end of the cylinder 1. Both sides of the feed rack 3 are connected to the cylinder 1 through fixing mechanisms 4. A first fixing rod 5 is fixedly connected to one side of the bottom end of the feed rack 3. Several first magnet plates 6 are connected at equal intervals along the length direction on the first fixing rod 5. A first gap 7 is provided between one side of each first magnet plate 6 and the inner wall of the cylinder 1. A first limiting strip 8 is fixedly connected to the upper end of the side of each first magnet plate 6 near the first gap 7. A second fixing rod 9 is fixedly connected to the other side of the bottom end of the feed rack 3. Several second magnet plates 10 are connected at equal intervals along the length direction on the second fixing rod 9. The several second magnet plates 10 are staggered with the several first magnet plates 6. A second gap 11 is provided between one side of each second magnet plate 10 and the inner wall of the cylinder 1. A second limiting strip 12 is fixedly connected to the upper end of the side of each second magnet plate 10 near the second gap 11.

[0016] Work process: The liquid to be filtered is poured into the feed rack 3. The liquid in the feed rack 3 falls onto the upper first magnetic plate 6. As the liquid flows on the first magnetic plate 6, the first magnetic plate 6 adsorbs iron impurities in the liquid. As the liquid flows towards the first gap 7, it contacts the first limiting strip 8. The first limiting strip 8 buffers the liquid. As the liquid at the upper end of the first magnetic plate 6 gradually increases, the liquid at the upper end of the first magnetic plate 6 overflows the first limiting strip 8 and is released from the first gap 7. The liquid released from the first gap 7 falls onto the second magnetic plate 10. As the liquid flows on the second magnetic plate 10, the second magnetic plate 10 adsorbs iron impurities in the liquid. As the liquid flows towards the second gap 11, it contacts the second limiting strip 12. The second limiting strip 12 buffers the liquid. As the liquid at the upper end of the second magnetic plate 10 gradually increases, the liquid at the upper end of the second magnetic plate 10 overflows the second limiting strip 12 and is released from the second gap 11. As the liquid flows downward, it continuously comes into contact with the first magnet plate 6 and the second magnet plate 10. The increased contact area between the first magnet plate 6 and the second magnet plate 10 and the liquid, along with the buffering effect of the first limiting strip 8 and the second limiting strip 12, prolong the contact time between the first magnet plate 6 and the second magnet plate 10 and the liquid, thereby improving the adsorption effect of the first magnet plate 6 and the second magnet plate 10 on iron impurities in the liquid. The liquid after adsorption is released from the drain pipe 2.

[0017] Example 2: Refer to Figure 2 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the fixing mechanism 4 includes a threaded rod 41, one end of the threaded rod 41 is fixedly connected to the feed rack 3, a perforated plate 42 is fixedly connected to the cylinder 1, and the other end of the threaded rod 41 passes through the perforated plate 42 and is fixedly connected to a fixing nut 43. When fixing the feed rack 3, one end of the threaded rod 41 passes through the perforated plate 42, and the fixing nut 43 is rotated. The fixing nut 43 is connected to the threaded rod 41. After the fixing nut 43 contacts the bottom end of the perforated plate 42, it fixes the feed rack 3. The feed rack 3 is fixed quickly.

[0018] Example 3: Reference Figure 3 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a cleaning mechanism 13 is connected inside the feeding rack 3. The cleaning mechanism 13 includes a fixing ring 131, which is fixedly connected to the feeding rack 3. A filter screen 132 is fixedly connected to the upper end of the fixing ring 131. The filter screen 132 is a convex filter screen. A third fixing rod 133 is fixedly connected to the inner ring wall of the fixing ring 131. A support rod 134 is fixedly connected to the upper end of the third fixing rod 133. The upper end of the support rod 134 is in contact with the bottom end of the filter screen 132. The fixing ring 131 fixes the filter screen 132, and the third fixing rod 133 fixes the support rod 134. The support rod 134 supports the filter screen 132. The liquid in the feed rack 3 passes through the filter screen 132, and the filter screen 132 filters large particles in the liquid, thereby improving the liquid filtration effect.
