Description

Technical Field

[0001] This utility model relates to the field of pigment purifier technology, and in particular to a backwashing structure for a pigment purifier filter. Background Technology

[0002] In many industries such as coatings, inks, and printing and dyeing, the purity and quality of pigment pastes play a decisive role in the final quality of products. Pigment paste purifiers, as key equipment for ensuring pigment paste quality, effectively filter pigment pastes, removing impurities, particles, and other contaminants, thereby improving the purity and quality of the pigment paste. Therefore, they are widely used in related industries. However, with the continuous operation of pigment paste purifiers in actual production processes, an unavoidable problem gradually emerges. During the long-term filtration of pigment paste, the filtration mechanism continuously intercepts impurities and particles. These contaminants gradually accumulate, causing blockages in the filtration mechanism. Once the filtration mechanism is blocked, the filtration efficiency of the pigment paste will decrease significantly, and in severe cases, it may even affect the normal supply of pigment paste, thus negatively impacting the entire production process.

[0003] To address the problem of filter clogging, the commonly used method is backflushing. However, existing backflushing methods have several drawbacks. First, most pigment purifiers must be shut down for backflushing, directly disrupting production. This stoppage not only results in lost capacity but can also disrupt the entire production plan, causing economic losses for the company. Second, the backflushing process requires manual adjustment of multiple valves to ensure proper flow of the cleaning solution for backflushing the filter. This process is cumbersome, requiring operators with specialized knowledge and skills, and is time-consuming, reducing the overall operating efficiency of the equipment. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a backwashing structure for a color paste purification filter, which can solve the problems of troublesome cleaning and delays in the progress of backwashing filters.

[0006] To achieve the above objectives, this utility model proposes a backwashing structure for a pigment purification filter, including an inlet pipe and an outlet pipe. A diversion horizontal pipe is installed at one end of each of the inlet and outlet pipes. Two filter covers are installed between the two diversion horizontal pipes. A U-shaped diversion pipe is installed at one end of each of the two diversion horizontal pipes. A first valve pipe is rotatably connected to the inner wall of each of the two diversion horizontal pipes. A first through hole is opened on one side of each of the two first valve pipes. An inner filter element is installed on the inner wall of each of the two filter covers. The two diversion horizontal pipes are connected through the internal spaces of the two filter covers. A first external connecting pipe is installed on one side of one of the U-shaped diversion pipes, and a second external connecting pipe is installed on one side of the other U-shaped diversion pipe. The two U-shaped diversion pipes are respectively connected to the internal spaces of the corresponding diversion horizontal pipes. A second valve pipe is rotatably connected to the inner wall of each of the two U-shaped diversion pipes. A second through hole is opened on one side of each of the two second valve pipes.

[0007] The backwashing structure of this utility model's pigment purification filter, through the coordinated use of two diversion horizontal pipes, two filter covers, and two U-shaped diversion pipes, realizes two interchangeable pigment channels and cleaning channels. This ensures that cleaning the inner filter element does not affect the filtration of pigment by the other inner filter element, improving work efficiency, avoiding downtime that affects pigment production, and the alternating use of the two inner filter elements can reduce the occurrence of emergency blockages and maintain continuous production.

[0008] In addition, the backwashing structure of the pigment purification filter proposed above according to this utility model may also have the following additional technical features:

[0009] Specifically, each of the two filter cover sidewalls is equipped with a fixing ring, and two reinforcing plates are installed between the two fixing rings.

[0010] Specifically, an adjusting rod is installed between the two diversion horizontal pipes, with both ends of the adjusting rod installed at the ends of the two first valve pipes, and the adjusting rod passing through the ends of the two second valve pipes.

[0011] Specifically, the adjusting rod is provided with two gears, one of which is installed on the side wall of the adjusting rod, and a horizontal plate is fixedly connected to the inner side of the reinforcing plate. A drive motor is installed at the bottom end of the horizontal plate, and the other gear is installed at the output end of the drive motor. The two gears are meshed together.

[0012] Specifically, two indicator plates are installed on the side wall of the adjusting rod. The two indicator plates do not correspond to the position of the reinforcing plate, and the positions of the two indicator plates are symmetrically distributed.

[0022] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0023] The following description, in conjunction with the accompanying drawings, describes a backwashing structure for a pigment purification filter according to an embodiment of the present invention.

[0024] like Figures 1-5As shown in the figure, a backwashing structure for a pigment purification filter according to an embodiment of the present invention may include an inlet pipe 1 and an outlet pipe 11. A diversion horizontal pipe 2 is installed at one end of each of the inlet pipe 1 and the outlet pipe 11. Two filter covers 3 are installed between the two diversion horizontal pipes 2. A U-shaped diversion pipe 4 is installed at one end of each of the two diversion horizontal pipes 2.

[0025] Among them, the inner walls of the two diversion horizontal pipes 2 are rotatably connected to the first valve pipes 21, and the two first valve pipes 21 are provided with a first through hole 22 on one side.

[0026] It should be noted that the two first through holes 22 described in this embodiment are opened in the same direction.

[0027] The inner walls of the two filter covers 3 are each equipped with an inner filter element 31, and the two diversion horizontal pipes 2 are connected through the internal space of the two filter covers 3.

[0028] It should be noted that the inner filter element 31 described in this embodiment filters from top to bottom.

[0029] One of the U-shaped diversion pipes 4 has a first external pipe 41 installed on one side, and the other U-shaped diversion pipe 4 has a second external pipe 42 installed on one side. The two U-shaped diversion pipes 4 are respectively connected to the internal space of the corresponding diversion horizontal pipe 2. The inner walls of the two U-shaped diversion pipes 4 are rotatably connected to a second valve pipe 43, and a second through hole 431 is opened on one side of each of the two second valve pipes 43.

[0030] It should be noted that the two second through holes 431 described in this embodiment are opened in the same direction, and the second through holes 431 are opposite to the first through hole 22.

[0031] Specifically, the inlet pipe 1 and outlet pipe 11 transport the pigment paste, and two diversion horizontal pipes 2 divert the pigment paste. The diversion horizontal pipe 2 achieves valve reversal through the internal first valve pipe 21, thereby allowing the first through hole 22 to connect with the two filter covers 3 respectively. The two filter covers 3 filter and purify the flowing pigment paste through the corresponding inner filter element 31, so that impurities can be intercepted inside the inner filter element 31. The filtered pigment paste enters the lower diversion horizontal pipe 2, and the lower diversion horizontal pipe 2 connects with the corresponding first... A valve tube 21 and a first through-hole 22 guide the pigment into the drain pipe 11 for discharge. Simultaneously, the pigment can flow on one side but cannot enter the other side of the diversion horizontal pipe 2 or the other filter cover 3, achieving unidirectional flow. When the inner filter element 31 needs cleaning, the first valve tube 21 is rotated, allowing the first through-hole 22 to connect with the other side of the diversion horizontal pipe 2, enabling the pigment to be purified and filtered by the other inner filter element 31. While one inner filter element 31 is in filtration operation, the other... The inner filter element 31 and the cavity on the other side of the two diversion horizontal pipes 2 are in standby mode. At this time, their interiors are being flushed. The two U-shaped diversion pipes 4 function similarly to the two diversion horizontal pipes 2. The lower U-shaped diversion pipe 4 is connected to an external cleaning water source through the first external connector 41. The water source enters the diversion horizontal pipe 2 without affecting the color paste flowing on the other side. The cleaning water enters the standby filter cover 3 to backwash the inner filter element 31, thus cleaning it. The waste liquid after cleaning passes through the U-shaped diversion pipe 4 and the second external connector 42. Similarly, when the two second valve pipes 43 are used with the first valve pipe 21, the second through hole 431 is connected to the cavity on one side of the U-shaped diversion pipe 4, so that the water source cannot enter the other side of the U-shaped diversion pipe 4 and affect the flow of the color paste. This ensures that cleaning the inner filter element 31 will not affect the filtration of the color paste by the other inner filter element 31, thereby improving work efficiency, avoiding downtime and affecting the production of color paste. Furthermore, the alternating use of the two inner filter elements 31 can reduce the occurrence of emergency blockage and maintain continuous production.

[0032] In one embodiment of this utility model, such as Figures 1-5 As shown, both filter covers 3 have fixing rings 5 ​​installed on their side walls, and two reinforcing plates 51 are installed between the two fixing rings 5.

[0033] It should be noted that the two reinforcing plates 51 described in this embodiment are symmetrically distributed between the two fixing rings 5.

[0034] Specifically, the two fixing rings 5 ​​are connected and fixed by two reinforcing plates 51, thereby reinforcing the two filter covers 3 and improving the stability of the device during use.

[0035] In one embodiment of this utility model, such as Figures 1-5As shown, an adjusting rod 6 is installed between the two diversion horizontal pipes 2. The two ends of the adjusting rod 6 are respectively installed at the ends of the two first valve pipes 21, and the adjusting rod 6 passes through the ends of the two second valve pipes 43.

[0036] It should be noted that the diameter of the adjusting rod 6 described in this embodiment is smaller than the inner diameter of the second valve tube 43.

[0037] Specifically, the adjusting rod 6 connects the four valve bodies in series, so that the two first valve tubes 21 and the two second valve tubes 43 can be controlled by the adjusting rod 6. When the adjusting rod 6 rotates, it drives the four valve bodies to rotate synchronously, so that the first valve tube 21 can rotate into the inner cavity on the other side of the diversion horizontal pipe 2, and the second through hole 431 can rotate into the inner cavity on the other side of the U-shaped diversion pipe 4. Furthermore, the two second through holes 431 and the two first through holes 22 are oriented in opposite directions, so that the cleaning fluid and pigment paste used for backflushing will not conflict when used at the same time.

[0038] In one embodiment of this utility model, such as Figures 1-5 As shown, the adjusting rod 6 is provided with two gears 61. One gear 61 is installed on the side wall of the adjusting rod 6. A horizontal plate 52 is fixedly connected to the inner side of one of the reinforcing plates 51. A drive motor 53 is installed at the bottom of the horizontal plate 52. The other gear 61 is installed at the output end of the drive motor 53. The two gears 61 are meshed together.

[0039] It should be noted that the two gears 61 described in this embodiment are at the same height.

[0040] Specifically, the reinforcing plate 51 supports the drive motor 53 through the cross plate 52. The drive motor 53 drives the corresponding gear 61 to rotate. When the gear 61 rotates, it drives another gear 61 to rotate synchronously. This gear 61 drives the adjusting rod 6 to rotate, so that the gear 61 can drive the four valve bodies to rotate synchronously, thus completing the rapid switching of the passage.

[0041] In one embodiment of this utility model, such as Figures 1-5 As shown, two indicator plates 62 are installed on the side wall of the adjusting rod 6. The two indicator plates 62 do not correspond to the position of the reinforcing plate 51, and the positions of the two indicator plates 62 are symmetrically distributed.

[0042] Specifically, the adjusting rod 6 supports the two indicator plates 62, which are not obstructed by the reinforcing plate 51. The two indicator plates 62 indicate the angle of the adjusting rod 6, making it easy for the staff to determine which filter cover 3 the pigment is flowing in at this time.

[0043] In summary, the backwashing structure of the pigment purification filter in this embodiment of the present invention, during use, allows the pigment to enter the inner cavity of one side of the diversion horizontal pipe 2 through the inlet pipe 1 and the first valve pipe 21. Guided and filtered by the filter cover 3 and the inner filter element 31, it then enters the inner cavity of the lower diversion horizontal pipe 2, and is then guided by the lower first valve pipe 21 to the drain pipe 11 for discharge, thus achieving filtration and purification. The drive motor 53 drives the corresponding gear 61 to rotate. When gear 61 rotates, it drives another gear 61 to rotate synchronously, and this gear 61 drives the adjusting rod 6 to rotate, thereby causing gear 61 to rotate. It can drive four valve bodies to rotate synchronously, complete the rapid switching of the passage. The lower U-shaped diversion pipe 4 is connected to the external cleaning water source through the first external pipe 41. The water source enters the diversion horizontal pipe 2 without affecting the color paste flowing on the other side. The cleaning water enters the standby filter cover 3 to backwash the inner filter element 31 and clean it. The waste liquid after cleaning is discharged through the U-shaped diversion pipe 4 and the second external pipe 42, so that the cleaning of the inner filter element 31 will not affect the filtration of the color paste by the other inner filter element 31, improve working efficiency, and avoid downtime affecting the production of color paste.

[0044] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
