Description

Technical Field

[0001] This utility model relates to the technical field of slurry conveying equipment, specifically a slurry distribution box for a stacked high-frequency vibrating fine screen. Background Technology

[0002] Slurry conveying is a crucial step in mining production. After the replacement of the stacked screen in the mineral processing plant, the limited space makes it difficult to effectively convey the slurry. In existing technologies, slurry is mostly conveyed to various pipelines through a slurry distribution box. However, due to the large volume of the distribution box, this operation can result in uneven material distribution. Therefore, a distribution box is often used to ensure uniform material distribution.

[0003] Chinese Utility Model Patent Publication No. CN213349644U discloses a novel stacked high-frequency vibrating fine screen slurry distribution box. The specification of this novel stacked high-frequency vibrating fine screen slurry distribution box reveals that the combined design of the novel filter box and filter layer can effectively filter the slurry, removing impurities to facilitate subsequent processes. The combined design of the buffer block and partition plate ensures that the slurry is level when conveyed to the distribution pipe, allowing for simultaneous conveying and more uniform slurry delivery. However, this novel stacked high-frequency vibrating fine screen slurry distribution box lacks a guiding structure, which can easily lead to slurry accumulation and blockage in the discharge chamber during slurry delivery, hindering distribution. Furthermore, the lack of an adjustment structure makes single-zone adjustment difficult, making it inconvenient to selectively close individual distribution pipes based on actual working conditions, resulting in poor overall versatility of the distribution box. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a stacked high-frequency vibrating fine screen slurry distribution box, which can effectively solve the problems in the prior art. In the prior art, the lack of a guiding structure makes it easy for the slurry to accumulate and block in the feeding chamber when it is being fed, which makes it difficult to distribute the slurry. Furthermore, the lack of an adjustment structure makes it difficult to achieve single-zone adjustment, which makes it difficult to select and close individual distribution pipes according to actual working conditions, resulting in poor overall versatility of the distribution box.

[0005] The technical solution adopted by this utility model is: a stacked high-frequency vibrating fine screen slurry distribution box, including an outer material barrel and an inner material barrel. A partition plate is fixedly installed on the inner edge of the outer material barrel. A groove is opened in the outer material barrel through the partition plate. A guide plate is fixedly installed in the outer material barrel through the groove. A distribution pipe is provided on the outer edge of the inner material barrel. The distribution pipe is located directly above the groove. A limit plug is threaded to the end of the distribution pipe away from the inner material barrel.

[0006] Preferably, a flange is fixedly installed at the outer edge of the outer material barrel, and a mounting foot is fixedly installed on the outer wall of the outer material barrel. The end of the mounting foot away from the flange is provided with a mounting groove.

[0007] The above technical solution enables the connection between the outer material barrel and the stacked high-frequency vibrating fine screen through the flange. With the design of the mounting feet, the outer material barrel can be fixed through the mounting groove, which makes the overall distribution box less prone to displacement and loosening under high-frequency vibration conditions.

[0008] Preferably, the guide plate has a feeding groove extending from top to bottom, and a discharge pipe is fixedly installed on the guide plate through the feeding groove. The guide plate is designed with an inclination of 5° to 10°.

[0009] Through the above technical solution, the guide plate, combined with the design of a 5°~10° tilt angle, can be used with the feeding trough and the discharge pipe. When feeding, the slurry can be guided by gravity to flow smoothly, avoiding slurry accumulation and blockage, which would make it difficult to distribute. This makes it easier to ensure that the slurry supply to each screen layer is consistent, which helps to improve the screening accuracy of the fine screen.

[0010] Preferably, an installation column is fixedly installed at one end of the inner material barrel near the outer material barrel, the installation column is fixedly installed with the outer material barrel, and the installation column is fixedly installed with the partition plate.

[0011] Through the above technical solution, the inner material tank and the mounting column can be used to fix the inner wall of the outer material tank, preventing it from shaking during vibration. Furthermore, the mounting column is fixed to the partition plate, which further strengthens the position of the partition plate and prevents the slurry distribution from being disordered due to vibration displacement of the inner material tank and the partition plate; thus enhancing the overall structural rigidity.

[0012] Preferably, a connecting frame is fixedly installed on the outer wall of the inner material barrel, and the other end of the connecting frame away from the inner material barrel is fixedly installed to the inner wall of the outer material barrel. A flange is fixedly installed on the other end of the inner material barrel away from the outer material barrel.

[0013] Through the above technical solution, the radial displacement of the inner material barrel is further restricted by the even distribution of the connecting frame along the outer wall of the inner material barrel. Furthermore, the flange two is connected to the flange of the upstream slurry pump or conveying pipe by bolts, which facilitates the stable entry of slurry into the inner material barrel and avoids interface leakage caused by vibration during feeding.

[0014] Preferably, there are four identical distribution pipes, partition plates, and guide plates, with each of the four distribution pipes, partition plates, and guide plates corresponding one-to-one.

[0015] The above technical solution divides the interior of the outer material tank into four independent spaces by a partition plate. Each space corresponds to a guide plate and a distribution pipe. The slurry in the inner material tank is discharged simultaneously through the four distribution pipes and enters the guide plate of the corresponding space. It is then transported to the four screen layers of the fine screen. This makes it easy to adapt to the multiple screen layers of the stacked high-frequency vibrating fine screen and improves the practicality of the overall distribution box.

[0016] Preferably, the limiting plug has a first groove and a second groove on its outer edge. The limiting plug is fixedly installed with a first sealing sleeve and a second sealing sleeve through the first groove and the second groove. The first sealing sleeve and the second sealing sleeve are interference fit with the distribution pipe.

[0017] Through the above technical solution, the limiting plug is threadedly connected to the distribution pipe. When a single distribution pipe does not need to be fed, the limiting plug can be rotated and inserted into the distribution pipe to achieve single-zone adjustment. Furthermore, the sealing sleeve one and sealing sleeve two are connected to the distribution pipe to prevent leakage. The distribution pipe can be closed according to the actual working conditions, thereby improving the versatility of the overall distribution box and enabling it to cope with different situations.

[0018] Compared with the prior art, the present invention provides a stacked high-frequency vibrating fine screen slurry distribution box, which has the following beneficial effects: 1. The stacked high-frequency vibrating fine screen slurry distribution box, with the guide plate and the design of 5°~10° inclination angle, can be used with the feeding trough and the discharge pipe. When feeding, the slurry can be guided by gravity to flow smoothly, avoiding slurry accumulation and blockage, which would make it difficult to distribute. It can make the slurry supply of each screen layer consistent, which can improve the screening accuracy of the fine screen. 2. This stacked high-frequency vibrating fine screen slurry distribution box divides the interior of the outer material tank into four independent spaces by a partition plate. Each space corresponds to a guide plate and a distribution pipe. The slurry in the inner material tank is discharged simultaneously through the four distribution pipes, enters the guide plate of the corresponding space, and is then conveyed to the four screen layers of the fine screen. This design facilitates adaptation to the multiple screen layers of the stacked high-frequency vibrating fine screen. Furthermore, the distribution pipe is threadedly connected to a limiting plug. When a single distribution pipe does not need to discharge material, the limiting plug can be rotated to insert into the distribution pipe, enabling single-zone adjustment. The distribution pipe can be closed according to the actual working conditions, thereby improving the versatility of the overall distribution box and enabling it to cope with different situations.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: As Figure 1-8 As shown, the present invention provides a stacked high-frequency vibrating fine screen slurry distribution box, including an outer material barrel 1 and an inner material barrel 11. A partition plate 5 is fixedly installed on the inner edge of the outer material barrel 1. A groove 6 is opened in the outer material barrel 1 through the partition plate 5. A guide plate 7 is fixedly installed in the outer material barrel 1 through the groove 6. A distribution pipe 13 is provided on the outer edge of the inner material barrel 11. The distribution pipe 13 is located directly above the groove 6. A limit plug 14 is threadedly connected to the end of the distribution pipe 13 away from the inner material barrel 11.

[0023] Specifically, a flange 2 is fixedly installed on the outer edge of the outer material barrel 1, and a mounting foot 3 is fixedly installed on the outer wall of the outer material barrel 1. A mounting groove 4 is opened through the end of the mounting foot 3 away from the flange 2. The advantage is that the outer material barrel 1 and the stacked high-frequency vibrating fine screen are connected through the flange 2. With the design of the mounting foot 3, the outer material barrel 1 can be fixed through the mounting groove 4, which makes the overall distribution box less prone to displacement and loosening under high-frequency vibration conditions.

[0024] Specifically, the guide plate 7 has a feed trough 8 extending from top to bottom. The discharge pipe 9 is fixedly installed on the guide plate 7 through the feed trough 8. The guide plate 7 is designed with an inclination of 5° to 10°. The advantage is that, with the guide plate 7 and the 5° to 10° inclination angle, it can work with the feed trough 8 and the discharge pipe 9 to guide the slurry to flow smoothly by gravity when feeding, avoiding slurry accumulation and blockage, which would make it difficult to distribute. This makes it easier to ensure that the slurry supply to each screen layer is consistent, which helps to improve the screening accuracy of the fine screen.

[0025] Specifically, an installation column 10 is fixedly installed at one end of the inner material tank 11 near the outer material tank 1. The installation column 10 is fixedly installed with the outer material tank 1 and with the partition plate 5. The advantage is that, through the cooperation of the inner material tank 11 and the installation column 10, the inner material tank 11 can be fixed to the inner wall of the outer material tank 1 by the installation column 10, preventing it from shaking during vibration. Furthermore, the installation column 10 is fixed to the partition plate 5, further reinforcing the position of the partition plate 5, which can prevent the slurry distribution from being disordered due to the displacement of the inner material tank 11 and the partition plate 5 due to vibration; and enhancing the overall structural rigidity.

[0026] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, a connecting frame 19 is fixedly installed on the outer wall of the inner material tank 11. The other end of the connecting frame 19 away from the inner material tank 11 is fixedly installed on the inner wall of the outer material tank 1. A flange 2 12 is fixedly installed on the end of the inner material tank 11 away from the outer material tank 1. The advantage is that the connecting frame 19 is evenly distributed along the outer wall of the inner material tank 11, which further restricts the radial displacement of the inner material tank 11. Furthermore, the flange 2 12 is connected to the flange of the upstream slurry pump or conveying pipe by bolts, which facilitates the stable entry of slurry into the inner material tank 11 and avoids interface leakage caused by vibration during feeding.

[0028] Specifically, there are four identical distribution pipes 13, partition plates 5, and guide plates 7. The four distribution pipes 13, partition plates 5, and guide plates 7 are in one-to-one correspondence. The advantage is that the partition plates 5 divide the interior of the outer material tank 1 into four independent spaces, each space corresponding to a guide plate 7 and a distribution pipe 13. The slurry in the inner material tank 11 is discharged simultaneously through the four distribution pipes 13, enters the guide plates of the corresponding spaces, and is then transported to the four screen layers of the fine screen. This facilitates the adaptation to the multiple screen layers of the stacked high-frequency vibrating fine screen and improves the overall practicality of the distribution box.

[0029] Specifically, the limiting plug 14 has a slot 15 and a slot 2 16 on its outer edge. The limiting plug 14 is fixedly installed with a sealing sleeve 17 and a sealing sleeve 2 18 through the slot 15 and the slot 2 16. The sealing sleeve 17 and the sealing sleeve 2 18 are interference fit with the distribution pipe 13. The advantage is that the limiting plug 14 is threadedly connected to the distribution pipe 13. When a single distribution pipe 13 does not need to be fed, the limiting plug 14 can be rotated and inserted into the distribution pipe 13 to achieve single-zone adjustment. Furthermore, the sealing sleeve 17 and the sealing sleeve 2 18 can prevent leakage from the distribution pipe 13. The distribution pipe 13 can be closed according to the actual working conditions, thereby improving the versatility of the overall distribution box and being able to cope with different situations.

[0030] Working Principle: During use, the outer material tank 1 is connected to the stacked high-frequency vibrating fine screen via flange 2. With the design of mounting feet 3, the outer material tank 1 can be fixed via mounting groove 4, preventing displacement and loosening of the entire distribution box under high-frequency vibration conditions. The guide plate 7, with its 5°–10° tilt angle, works in conjunction with the discharge chute 8 and discharge pipe 9. During discharge, gravity guides the slurry to flow smoothly, preventing slurry accumulation and blockage, which would hinder distribution. This ensures consistent slurry supply to each screen layer, improving the screening accuracy of the fine screen. The inner material tank 11 and mounting column 10 work together to fix the inner wall of the outer material tank 1, preventing it from shaking during vibration. The mounting column 10 is also fixed to the partition plate 5, further reinforcing the position of the partition plate 5 and preventing slurry distribution disorder caused by vibration displacement of the inner material tank 11 and partition plate 5. This enhances the overall structural rigidity. The connecting frame 19 is evenly distributed along the outer wall of the inner material tank 11, further... The radial displacement of the inner material tank 11 is limited, and the flange 2 12 is bolted to the flange of the upstream slurry pump or conveying pipe, which facilitates the stable entry of slurry into the inner material tank 11 and avoids interface leakage caused by vibration during feeding. The partition plate 5 divides the interior of the outer material tank 1 into four independent spaces, each space corresponding to a guide plate 7 and a distribution pipe 13. The slurry in the inner material tank 11 is discharged simultaneously through the four distribution pipes 13, enters the guide plate of the corresponding space, and is then conveyed to the four screen layers of the fine screen. This facilitates the adaptation to the multiple screen layers of the stacked high-frequency vibrating fine screen and improves the practicality of the overall distribution box. The limit plug 14 is threadedly connected to the distribution pipe 13. When a single distribution pipe 13 does not need to discharge material, the limit plug 14 can be rotated and inserted into the distribution pipe 13 to achieve single-zone adjustment. The sealing sleeve 17 and sealing sleeve 2 18 are connected to the distribution pipe 13 to prevent leakage. The distribution pipe 13 can be closed according to the actual working conditions, thereby improving the versatility of the overall distribution box and being able to cope with different situations.
