Description

Technical Field

[0001] The utility model relates to the technical field of desanders for a cooking circulation line, in particular to a slag collecting device for a desander for a cooking circulation line. Background Art

[0002] The slag collection of the desander of the cooking circulation line utilizes existing resources to achieve efficient and environmentally friendly operations. The specific approach is to cleverly combine the waste ton barrels with the filter screen of the black liquor fiber filter. During operation, first place the filter screen of the fiber filter securely inside the ton barrel, and place the assembled device accurately below the slag discharge port of the desander. When the desander starts to discharge slag, the waste liquid containing impurities is first carefully filtered by the filter screen, and the black liquor components therein pass through the filter screen smoothly and are discharged into the ditch through a dedicated ground drainage pipe, thus achieving effective separation of the black liquor, and solid impurities such as sand mixed in the waste liquid are effectively intercepted by the filter screen and accumulated inside the filter screen. To ensure the cleanliness and safety of the production environment, staff will regularly use forklifts to transport the filter screen full of sand together with the ton barrels to the designated area for centralized treatment, which not only realizes the reuse of resources but also ensures the smooth operation of the production line.

[0003] Although the slag collection device that combines waste ton barrels with black liquor fiber filter screens has solved the slag discharge problem of the cooking circulation line desander to a certain extent, it still exposes several technical defects in actual application. During the regular cleaning process, since the entire ton barrel needs to be forked out by a forklift, black liquor is easily dripped from the connection between the ton barrel and the discharge ground during transportation, which not only causes environmental pollution, but also increases the extra cleaning workload. Secondly, although the filter screen can effectively intercept most of the sand, the filtered black liquor still contains a certain amount of fine sand. After these black liquors containing fine sand flow into the ditch, they are not only difficult to clean, but may also cause pipeline blockage due to the deposition of fine sand.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] Combine Figures 1-6 As shown, the utility model is a desander slag collection device for a cooking circulation line, comprising a desander slag outlet 1, wherein the desander slag outlet 1 can discharge sediment and waste liquid, and further comprising:

[0046] The collecting frame 2 is arranged just below the slag discharge port 1 of the desander, wherein a ground connection discharge port 3 communicating with the collecting frame 2 is also provided on the side wall of the collecting frame 2;

[0047] The crossbeam 4 is fixedly mounted on the inner side wall of the collecting frame 2 and is spaced a certain distance from the inner bottom wall of the collecting frame 2. The area between the inner bottom wall of the collecting frame 2 and the crossbeam 4 is the secondary sedimentation area.

[0048] The grid plate 5 is arranged on the inner side of the collecting frame 2, wherein the grid plate 5 can be displaced along the length direction of the collecting frame 2;

[0049] The filter assembly 6 is placed above the grid plate 5 and is connected to the desander discharge port 1. It is used to filter the sediment and waste liquid discharged from the desander discharge port 1. The waste liquid and a small amount of sediment can flow into the secondary sedimentation area for sedimentation. The waste liquid is discharged from the discharge port 3, and the sediment is retained in the secondary sedimentation area.

[0050] The collecting groove 7 is provided on the inner bottom wall of the collecting frame 2 and is perpendicular to the crossbeam 4;

[0051] The bottom cleaning assembly 8 is arranged on the inner side of the collecting frame 2 and is interconnected with the crossbeam 4. It can be displaced along the length direction of the crossbeam 4 to clean a small amount of sediment in the secondary sedimentation area into the collecting ditch 7.

[0052] After the mixture of sediment and waste liquid is discharged from the desander discharge port 1, it will directly fall into the collection frame 2 arranged directly below it. The collection frame 2 serves as a main collection container. Its design is spacious enough to accommodate a large amount of sediment and waste liquid, and a drainage connection discharge port 3 is provided on its side wall for subsequent discharge of treated waste liquid.

The main function of the filter component 6 is to filter out the sediment particles and only allow the waste liquid to pass through. After the filtering action of the filter component 6, the waste liquid and some fine sediment particles will continue to fall and flow under the grid plate 5. In the secondary sedimentation area, the waste liquid will further settle, and the fine sand particles therein will gradually settle at the bottom, while the clearer waste liquid will gradually accumulate on the top. As time goes by, the clearer waste liquid will be discharged from the collection frame 2 through the drainage connection outlet 3 and enter the subsequent treatment process. At the same time, the sand particles in the secondary sedimentation area will gradually accumulate. In order to clean up these sands, a bottom cleaning component 8 is provided in the device. The bottom cleaning component 8 is connected to the crossbeam 4 and can be displaced along the length direction of the crossbeam 4. When the sand needs to be cleaned, the bottom cleaning component 8 will move along the crossbeam 4 and push the sand particles in the secondary sedimentation area into the collection groove 7 opened on the bottom wall of the collection frame 2 for subsequent treatment and discharge.

[0053] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 As shown; the grid plate 5 includes:

[0054] The displacement plate 51 is arranged on the outside of the collecting frame 2, wherein a moving wheel 52 is further arranged on the surface of the displacement plate 51;

[0055] The grid bars 53 are fixedly mounted on one side surface of the displacement plate 51. The number of grid bars 53 is set to be distributed evenly on the displacement plate 51 in an array, wherein the end of the grid bar 53 away from the displacement plate 51 extends to the inner side of the collection frame 2. The displacement plate 51 is arranged on the outer side of the collection frame 2. Its main function is to provide a stable support surface. At the same time, moving wheels 52 are also provided. These moving wheels 52 can reduce the friction between the displacement plate 51 and the ground, so that the staff can easily push the grid plate 5 to move. The grid bars 53 are fixedly mounted on one side surface of the displacement plate 51. They are arranged in an array with equal distances. The main function of the grid bars 53 is to support the entire filter assembly 6.

[0056] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 As shown; the filter assembly 6 includes:

[0057] The connecting tube 61 is placed on the surface of the grid bar 53, and its upper and lower ends are both open;

[0058] The fiber filter screen 62 is fixedly mounted on the inner side of the connecting tube 61 and is used to filter the sediment and waste liquid discharged from the desander discharge port 1; and

[0059] The connecting piece 63 is arranged on the connecting cylinder 61 and is connected to the desander discharge port 1 through a flange, wherein the connecting piece 63 is used to connect the connecting cylinder 61 to the desander discharge port 1. The connecting cylinder 61 is placed on the surface of the grid bar 53, and its upper and lower ends are designed to be open. Such a structure allows the sediment and waste liquid mixture to smoothly enter and pass through the connecting cylinder 61. The connecting cylinder 61 not only provides a stable support platform for the fiber filter screen 62, but also ensures the smooth progress of the filtration process. Next, the fiber filter screen 62 is fixedly installed on the inner side of the connecting cylinder 61. This is a high-efficiency filter material. Its fine fiber structure can effectively intercept sediment particles and allow waste liquid to pass through. When the sediment and waste liquid mixture is discharged from the desander discharge port 1 and falls into the connecting cylinder 61, they will first contact the fiber filter screen 62. At this time, most of the sediment The particles will be intercepted by the fiber filter screen 62 and retained above it to form a sand layer, and the waste liquid that has been preliminarily filtered will continue to flow downward, pass through the fiber filter screen 62 and flow to the secondary sedimentation area below. It is worth noting that although the fiber filter screen 62 can intercept most of the sand particles, there will still be a small number of fine sand particles passing through the filter screen along with the waste liquid and entering the secondary sedimentation area. These fine sand particles will be further precipitated in the secondary sedimentation area. In order to ensure that the connecting tube 61 can be stably connected to the desander discharge port 1, a connecting piece 63 is provided in the device. The connecting piece 63 is provided on the connecting tube 61 to tightly connect the connecting tube 61 to the desander discharge port 1. This design not only ensures that the sand and waste liquid mixture can smoothly enter the connecting tube 61 from the desander discharge port 1, but also improves the stability of the entire filter assembly 6.

[0060] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 、 Figure 2As shown; a U-shaped guide rail 9 is fixedly installed on the surface of the crossbeam 4, wherein the number and distribution positions of the U-shaped guide rail parts 9 are adapted to each other, and the grid bars 53 are slidably connected to the inner sides of the U-shaped guide rail parts 9, and a moving plate 10 is also fixedly installed on the inner side wall of the collection frame 2, wherein the end of the grid bar 53 away from the displacement plate 51 can be placed above the moving plate 10. The crossbeam 4, as an important structure inside the collection frame 2, not only provides a support function, but also serves as a guide reference for the displacement of the grid bars 53. On the surface of the crossbeam 4, a U-shaped guide rail part 9 is fixedly installed. The number and distribution positions of these U-shaped guide rail parts 9 are carefully designed to ensure that they can adapt to each other with the grid bars 53. Specifically, each grid bar 53 can be slidably connected to the inner side of the corresponding U-shaped guide rail part 9. This design enables the grid bar 53 to move along the trajectory of the U-shaped guide rail part 9, thereby ensuring its movement. Smoothness and accuracy. In order to further enhance the stability of the grid bars 53 during movement, a retaining plate 10 is fixedly installed on the inner wall of the collection frame 2. When the grid bar 53 is displaced under the guidance of the U-shaped guide rail 9, its end away from the displacement plate 51 will gradually approach and eventually be placed above the retaining plate 10. The retaining plate 10 plays an important supporting role here. It can effectively support the end of the grid bar 53 to prevent it from tilting or falling off due to uneven force during movement. Through such a design, the grid bar 53 can achieve smooth and reliable displacement under the joint action of the U-shaped guide rail 9 and the retaining plate 10, which not only improves the working efficiency of the entire device, but also ensures its stability and durability during long-term operation. At the same time, such a design also makes it convenient for the staff to clean and maintain the grid plate 5, because the grid plate 5 can be easily taken out or put back from the collection frame 2 by simply pushing it along the direction of the U-shaped guide rail 9.

[0061] In a preferred embodiment, the present invention can be further configured as follows: Figures 3 to 6 As shown; bottom cleaning assembly 8 includes:

[0062] A sliding member 81 is slidably connected to a surface of the beam 4 near the secondary sedimentation area;

[0063] The mounting bracket 82 is fixedly mounted on the surface of the sliding member 81 and can be displaced synchronously with the movement of the sliding member 81;

[0064] The rotating rod 83 is rotatably connected to the surface of the mounting frame 82 and can be axially rotated on the surface of the mounting frame 82;

[0065] The scraper 84 is fixedly mounted on the surface of the rotating rod 83;

[0066] a fastener 85 disposed on the scraper 84 and connected to the mounting bracket 82 to fix the position of the scraper 84; and

[0067] The take-up drum 86 is fixedly mounted on the outer wall of the collection frame 2, wherein a pull rope 87 is fixedly mounted on the take-up end of the take-up drum 86, and the other end of the pull rope 87 passes through the side wall of the collection frame 2 and is connected to the sliding member 81. The sliding member 81 is slidably connected to the side surface of the beam 4 close to the secondary sedimentation area. Since the beam 4 is arranged in an n-shaped manner, its opening provides a stable sliding track for the sliding member 81. This design enables the sliding member 81 to move smoothly along the length direction of the beam 4. Then, the mounting bracket 82 is fixedly mounted on the surface of the sliding member 81. As the sliding member 81 As the scraper 84 moves, the mounting frame 82 will also move synchronously. This design ensures that the scraper 84 can cover the entire secondary sedimentation area as the sliding member 81 moves, thereby achieving comprehensive cleaning of the sediment. The scraper 84 is fixedly mounted on the surface of the rotating rod 83. Its function is to directly scrape the sediment in the secondary sedimentation area. In order to ensure that the scraper 84 can be stably fixed on the mounting frame 82, a fastener 85 is also provided to connect the scraper 84 and the mounting frame 82. Finally, the take-up drum 86 is fixedly mounted on the outer wall of the collection frame 2, and a pull rope 87 is fixedly mounted on the take-up end of the take-up drum 86. The other end of the rope 87 passes through the side wall of the collection frame 2 and is connected to the sliding member 81. This design allows the staff to reel in the rope 87 by operating the reel 86, thereby controlling the displacement of the sliding member 81 and the mounting frame 82. When cleaning the sediment, the staff can reel in the rope 87 through the reel 86, thereby driving the sliding member 81 and the mounting frame 82 to move along the crossbeam 4. As the mounting frame 82 moves, the scraper 84 will continuously scrape the sediment in the secondary sedimentation area and collect it in the collection ditch 7. It is worth noting that in order to ensure that the entire mounting frame 82 moves In order to ensure smooth movement, rollers are provided on the ends of the mounting frame 82. The outer surfaces of these rollers can contact with the inner surface of the collection frame 2, thereby reducing the friction of the mounting frame 82 during movement and improving the smoothness and efficiency of its movement. It should also be noted that the starting position of the scraper 84 is close to the inner left bottom wall of the collection frame 2. During the scraping process, as the mounting frame 82 moves, when the mounting frame 82 moves to the far right and contacts with the inner right wall of the collection frame 2, the scraper 84 just scrapes the sediment into the collection groove 7, so there will be no obstruction, residue or unclean scraping.

[0068] In a preferred embodiment, the present invention can be further configured as follows: Figure 4 、 Figure 5 As shown; the fastener 85 includes:

[0069] The connecting seat 851 is fixedly mounted on the surface of the scraper 84, wherein a connecting hole is machined at the center of the connecting seat 851;

[0070] A first threaded hole 852 is provided on the mounting bracket 82;

[0071] A second threaded hole 853 is formed on the mounting bracket 82; and

[0072] The hand-tightening nut 854 passes through the connecting hole on the connecting seat 851 and is connected to the first threaded hole 852 or the second threaded hole 853. The connecting seat 851 is fixedly mounted on the surface of the scraper 84, and a connecting hole is processed at the center. This connecting hole provides a passage for the hand-tightening nut 854 to pass through, so that the scraper 84 can be connected to the mounting bracket 82 through the fastener 85. Then, the first threaded hole 852 and the second threaded hole 853 are respectively opened on the mounting bracket 82. The positions and spacings of these two threaded holes are carefully designed to ensure that they can achieve stable threaded connection with the hand-tightening nut 854. At the same time, the two threaded holes also correspond to the two states of contact and non-contact between the scraper 84 and the inner bottom wall of the collection frame 2. When it is necessary to clean the collection frame 2 When there is sedimentation at the bottom, the staff can pass the hand-tightening nut 854 through the connecting hole on the connecting seat 851 and tighten it to the inner side of the first threaded hole 852. At this time, one end of the scraper 84 will be in close contact with the inner bottom wall of the collection frame 2. Under traction and stretching, the scraper 84 will scrape the sediment as the mounting frame 82 moves and collect it into the collection ditch 7. When there is no need to clean the sediment and only waste liquid needs to be discharged, the staff can loosen the hand-tightening nut 854 and unscrew it from the first threaded hole 852. Then, pass the hand-tightening nut 854 through the connecting hole and tighten it to the inner side of the second threaded hole 853. At this time, the scraper 84 will no longer be in contact with the inner bottom wall of the collection frame 2, thereby allowing the waste liquid to be discharged normally from the drainage connection outlet 3 without being hindered by the scraper 84.

[0073] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 、 Figure 2 As shown; a discharge gate interconnected with the collecting groove 7 is provided on the surface of the collecting frame 2. In the slag collection device of the desander in the cooking circulation line, the collecting frame 2 serves as the main slag collection component. Its design fully considers the collection, storage and discharge requirements of the settled sand. A collecting groove 7 is provided at the bottom of the collecting frame 2. The main function of the collecting groove 7 is to collect the settled sand scraped by the bottom cleaning component 8. As the scraper 84 moves on the mounting frame 82, the settled sand is continuously scraped into the collecting groove 7, thereby realizing the effective collection of the settled sand. In order to further facilitate the discharge of the settled sand, a discharge gate 11 interconnected with the collecting groove 7 is also provided on the surface of the collecting frame 2. The design of the discharge gate 11 allows the staff to open or close the discharge port at any time according to actual needs, thereby controlling the discharge of the settled sand. When the settled sand needs to be discharged, the staff only needs to open the discharge gate 11, and the settled sand in the collecting groove 7 will be discharged from the collecting frame 2 smoothly through the discharge gate 11 under the action of gravity.

[0074] The specific working principle of the desander slag collection device of the cooking circulation line of the utility model is as follows:

[0075] The desander discharge collection device of the cooking circulation line is installed just below the desander discharge port 1 to ensure that the collection frame 2 can accurately receive the sediment and waste liquid discharged from the desander discharge port 1. The desander discharge port 1 starts to discharge sediment and waste liquid. These substances first enter the filter assembly 6. The waste liquid and sediment are filtered by the fiber filter screen 62. The waste liquid flows downward to the secondary sedimentation area. At the same time, part of the sediment will also flow into the secondary sedimentation area for precipitation, while the larger sediment particles are retained above the fiber filter screen 62.

[0076] As the cooking circulation line continues to operate, the displacement plate 51 can be pulled to the side away from the abutment plate 10 to clean the fiber filter screen 62. In the secondary sedimentation area, the sediment gradually settles and accumulates on the inner bottom wall of the collection frame 2. In order to clean the sediment, the bottom cleaning component 8 can be operated. First, the pull rope 87 is wound through the take-up drum 86. The other end of the pull rope 87 is connected to the sliding member 81. As the pull rope 87 is tightened, the sliding member 81 slides along the opening of the beam 4, driving the mounting frame 82 to move synchronously. The roller on the mounting frame 82 contacts the inner surface of the collection frame 2 to ensure the stability of the movement. During the displacement of the mounting frame 82, the scraper 84 on the rotating rod 83 scrapes the sediment on the inner bottom wall of the collection frame 2 into the collection groove 7. The position of the scraper 84 can be adjusted by the fastener 85. When it is necessary to clean the sediment, the hand nut 854 is unscrewed from the second threaded hole 853 and tightened to the inner side of the first threaded hole 852. At this time, one end of the scraper 84 is in close contact with the inner bottom wall of the collection frame 2 to ensure the sand scraping effect. When it is not necessary to clean the sediment, the hand nut 854 is tightened to the inner side of the second threaded hole 853 to keep a certain distance between the scraper 84 and the inner bottom wall of the collection frame 2, allowing the waste liquid to be discharged normally from the drainage connection outlet 3;

[0077] Finally, when the sediment in the collection ditch 7 accumulates to a certain extent, the discharge gate 11 can be opened to discharge the sediment from the collection frame 2. The setting of the discharge gate 11 makes the discharge of sediment more convenient and flexible;

[0078] Through the above steps, the desander slag collection device of the cooking circulation line realizes the effective separation, collection and discharge of sediment and waste liquid, providing a strong guarantee for the normal operation of the cooking circulation line.
