Description

Technical Field

[0001] This utility model belongs to the field of centrifuge technology, specifically relating to an adjustable cleaning tube structure for a pusher centrifuge used for direct separation of heavy alkali. Background Technology

[0002] In the production process of push-feed centrifuges used for direct separation of heavy alkali, regular cleaning of the centrifuge interior is necessary to ensure separation efficiency and product quality. The cleaning pipe structure is a key component for effective cleaning. In existing technologies, the cleaning pipe structure of push-feed centrifuges is mostly designed for fixed installation. The wash water pipe and annular pipe are typically fixed directly to the centrifuge product chamber door or a corresponding mounting base, and their position cannot be adjusted according to the actual production process. However, in actual heavy alkali separation production, due to differences in process parameters such as material concentration, throughput, and separation requirements, fixed-position cleaning pipes cannot accurately adapt to the cleaning needs under different process conditions. This easily leads to problems such as cleaning dead zones, incomplete cleaning, or low cleaning efficiency, resulting in residual material affecting subsequent separation effects or increasing equipment maintenance costs, and failing to ensure optimal cleaning results. To address the problems of poor cleaning adaptability and inadequate results caused by the fixed position of existing cleaning pipes, this utility model aims to provide an adjustable cleaning pipe structure for push-feed centrifuges used for direct separation of heavy alkali, enabling flexible adjustment of the cleaning position and solving the technical problem that existing cleaning pipes cannot adapt to different production process requirements.

[0003] Chinese Patent CN221433476U discloses a pusher centrifuge. The pusher centrifuge includes: a body defining a receiving cavity; a drum rotatably disposed within the receiving cavity, the drum having a separation chamber for solid-liquid separation of materials and an opening communicating with the separation chamber, and multiple drainage holes communicating with the separation chamber on the circumferential sidewall of the drum; and a cleaning component including a cleaning pipeline, one end of which receives cleaning liquid, and the other end extending into the separation chamber through the opening. The cleaning pipeline has nozzles facing the circumferential sidewall of the drum, so as to use the cleaning liquid sprayed from the nozzles to wash the multiple drainage holes. The above device achieves cleaning by the cleaning pipeline extending into the separation chamber through the opening and the nozzles facing the drainage holes on the circumferential sidewall of the drum. The overall cleaning pipeline structure is fixed in position, which means that the position of the cleaning pipeline and nozzles cannot be adjusted according to actual needs after installation. Therefore, there is an urgent need for those skilled in the art to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing technology, improve the flexibility of adjusting the position of the washing pipe, and make it applicable to more centrifuges of different specifications.

[0005] The technical solutions adopted in this utility model are as follows: An adjustable cleaning pipe structure for a pusher centrifuge used for direct separation of heavy alkali is provided, which is used to adjust the position of the washing water pipe and the annular pipe in the product chamber door of the centrifuge, including a washing water pipe seat, a washing water pipe, an adjusting bolt and an adjusting nut; The washing pipe seat is fixedly installed on the centrifuge product chamber door, the washing pipe is installed inside the washing pipe seat, the washing pipe seat has a mounting hole for installing the adjusting bolt, the inner side of the mounting hole is provided with a thread adapted to the adjusting bolt, and the mounting hole penetrates the washing pipe seat. The adjusting bolt is used to lock and fix the washing pipe to the washing pipe seat after it is adjusted to the target position. The adjusting nut cooperates with the adjusting bolt to achieve anti-loosening locking.

[0006] By adopting the above technical solution, the wash pipe seat is fixed to the centrifuge product chamber door, and the wash pipe is installed inside the seat and locked with adjusting bolts and prevented from loosening with adjusting nuts, thus achieving flexible adjustment of the wash pipe position. Its core advantage lies in breaking the limitations of traditional fixed washing pipes, allowing for dynamic adjustment of the washing position according to actual production process requirements, ensuring optimal cleaning results under different operating conditions, and solving the problem that fixed-position cleaning cannot adapt to diverse processes.

[0007] Furthermore, there are at least two washing pipes, which are spaced apart along the circumference of the annular pipe.

[0008] By adopting the above technical solution, the spaced arrangement of multiple washing pipes can rinse the areas inside the centrifuge to be cleaned, such as the inner wall of the drum and the drain hole, from different angles, avoiding cleaning dead corners caused by a single washing pipe, improving the uniformity and comprehensiveness of cleaning, and ensuring that all areas inside the centrifuge can be effectively rinsed.

[0009] Furthermore, at least one adjusting bolt is provided, and the adjusting bolt passes through the mounting hole and contacts the washing pipe.

[0010] By adopting the above technical solution, the washing pipe can be quickly fixed in position within the washing pipe seat by applying locking force through direct contact between the bolt and the pipe. The inclusion of at least one adjusting bolt meets basic locking requirements, resulting in a simple structure and convenient operation. This ensures that the washing pipe will not shift after being adjusted to the target position, guaranteeing the stability of the cleaning position.

[0011] Furthermore, the adjusting nut is a hexagonal anti-loosening nut, which, after being threadedly connected to the adjusting bolt, presses against the outer wall of the wash pipe seat.

[0012] By adopting the above technical solution and utilizing the anti-loosening properties of the hexagonal anti-loosening nut, the adjusting bolts can be effectively prevented from loosening due to vibration and other factors during equipment operation. This ensures the long-term stability of the washing pipe's fixed position, prevents displacement of the cleaning position due to bolt loosening, guarantees the continuity and reliability of the cleaning effect, and improves the structural safety of the device.

[0013] Furthermore, the wash water pipe seat is detachably fixed to the centrifuge product chamber door by bolts.

[0014] By adopting the above technical solution and using a detachable connection method, the installation, disassembly, and subsequent maintenance of the wash water pipe seat are facilitated. When the wash water pipe seat or the centrifuge product chamber door needs to be inspected or replaced, it can be quickly disassembled without damaging the overall structure, reducing maintenance difficulty and cost, and improving equipment maintenance efficiency.

[0015] Furthermore, at least two of the washing pipes are arranged in parallel, and an annular pipe is provided between the washing pipes, the annular pipe being welded between the washing pipes.

[0016] By adopting the above technical solutions, the parallel arrangement ensures the consistency and stability of the rinsing direction of the washing pipes, avoiding confusion in the rinsing direction caused by the tilting of the washing pipes; the welding connection of the ring pipes integrates the scattered washing pipes into a whole, enhancing the structural rigidity of the washing pipes and preventing them from shaking due to water flow impact during rinsing. At the same time, the ring pipes can help to evenly distribute the cleaning medium, further improving the stability of the cleaning effect.

[0017] This utility model has the following beneficial effects: 1. This utility model achieves flexible adjustment of the washing pipe position by installing the washing pipe in the washing pipe seat fixed on the product chamber door of the centrifuge, and by using the assembly relationship of adjusting bolts passing through the installation hole of the washing pipe seat and contacting and locking with the washing pipe, and adjusting nuts pressing the outer wall of the washing pipe seat to prevent loosening. It can dynamically adapt to different cleaning positions according to the production process requirements to ensure the best cleaning effect. 2. This utility model expands the cleaning coverage area by arranging at least two parallel washing pipes and distributing them at intervals along the circumference of the annular pipe, and by welding the annular pipe to the washing pipes in an assembly relationship, thus avoiding cleaning dead corners of a single washing pipe and improving the uniformity and comprehensiveness of cleaning. 3. This utility model, by adjusting the position of the bolt that passes through the mounting hole of the washing pipe seat and directly contacts the washing pipe, can quickly apply a locking force to the washing pipe that has been adjusted to the target position, ensuring that the washing pipe does not shift during operation and guaranteeing the stability of the cleaning position; 4. This utility model uses a bolted detachable connection between the wash water pipe seat and the centrifuge product chamber door, which facilitates the installation, disassembly and subsequent maintenance of the wash water pipe seat. It allows for quick inspection or replacement of parts without damaging the overall structure, reducing maintenance difficulty and cost. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this utility model. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the protection scope of this utility model.

[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As can be seen, the adjustable cleaning pipe structure of the pusher centrifuge for direct separation of heavy alkali in this utility model, with the washing pipe seat 2 serving as the overall installation base, is detachably fastened to the centrifuge product chamber door by bolt assembly. This connection method not only ensures the stable connection between the washing pipe seat 2 and the main body of the equipment, but also provides convenience for the installation, maintenance and replacement of subsequent components, allowing for quick disassembly without damaging the original structure of the equipment. The washing pipe seat 2 is equipped with at least two washing pipes 1, and at least two washing pipes 1 are distributed in a parallel state. To further enhance the structural integrity and cleaning synergy, an annular pipe is welded between the washing pipes 1. The annular pipe connects the washing pipes 1 into a unified whole along the circumferential direction, while the washing pipes 1 are spaced apart along the circumferential direction of the annular pipe. This layout not only improves the structural rigidity of the washing pipes 1 through the annular pipe, preventing them from shaking due to water flow impact during rinsing. The washing pipes 1, distributed at intervals, expand the cleaning coverage area and avoid dead corners caused by single-pipe rinsing. To achieve flexible adjustment and fixation of the position of the washing pipe 1, the washing pipe seat 2 has a through-hole that penetrates its thickness. The inner side of the mounting hole is machined with an internal thread that matches the adjusting bolt 3. At least one adjusting bolt 3 is provided. After passing through the mounting hole, it directly contacts the outer wall of the washing pipe 1. By tightening the adjusting bolt 3, a lateral locking force can be applied to the washing pipe 1 to ensure that the washing pipe 1 is rigidly fixed to the washing pipe seat 2 after being adjusted to the target position. To prevent the adjusting bolt 3 from loosening due to vibration during equipment operation, the adjusting nut 4 adopts a hexagonal anti-loosening nut structure. After being threadedly connected to the adjusting bolt 3, it tightly presses against the outer wall of the washing pipe seat 2. Through the friction between the nut and the seat and the self-locking effect of the thread pair, double anti-loosening is achieved, ensuring the long-term stability of the position of the washing pipe 1.

[0023] In one embodiment, refer to Figure 2 , Figure 3 and Figure 4As can be seen, firstly, by loosening the adjusting nut 4, the pressure on the outer wall of the washing pipe seat 2 is released. Then, the adjusting bolt 3 is loosened, separating it from the outer wall of the washing pipe 1. At this time, the washing pipe 1 is movable within the washing pipe seat 2. Next, according to the actual production process requirements, the washing pipe 1 is moved along a preset direction inside the washing pipe seat 2 and adjusted to the target position. After adjustment, the adjusting bolt 3 is tightened so that it passes through the mounting hole of the washing pipe seat 2 and makes tight contact with the outer wall of the washing pipe 1. The lateral locking force of the bolt on the washing pipe 1 fixes it within the washing pipe seat 2. Finally, the adjusting nut 4 is tightened so that it is threadedly connected to the adjusting bolt 3 and re-presses the outer wall of the washing pipe seat 2. The friction between the nut and the seat body and the self-locking effect of the threaded pair are used to achieve anti-loosening locking, ensuring that the washing pipe 1 will not shift its position due to vibration or other factors during equipment operation. By adjusting the bolt 3 to lock in direct contact with the washing pipe 1, adjusting the nut 4 to prevent loosening, and adjusting the washing pipe seat 2 to limit the position of the washing pipe 1, the precise adjustment and stable fixation of the washing pipe 1 are achieved.

[0024] In one embodiment, refer to Figure 5 As can be seen, in this device, firstly, according to the actual production process requirements, by loosening the adjusting nut 4 and adjusting bolt 3, at least two parallel washing pipes 1 are moved to the target cleaning position within the washing pipe seat 2. After adjustment, the adjusting bolt 3 is tightened so that it passes through the mounting hole of the washing pipe seat 2 and makes tight contact with the washing pipe 1 to lock and fix it. Then, the adjusting nut 4 is used to press the outer wall of the washing pipe seat 2 to prevent loosening. Subsequently, the cleaning medium enters the washing pipe 1 through the pipeline. The washing pipe 1 is evenly distributed to each washing pipe through a welded annular pipe. The medium is finally sprayed out from the nozzle on the pipe wall of the washing pipe 1, with the nozzle facing the area to be cleaned in the product chamber of the centrifuge. The multiple washing pipes 1 distributed at intervals along the circumference of the annular pipe form a multi-angle, full-coverage rinsing effect. At the same time, the overall connection of the annular pipe enhances the structural stability of the washing pipe 1, avoiding shaking due to water flow impact during rinsing, and ensuring that the cleaning medium can continuously and stably rinse the product chamber efficiently, thereby achieving the purpose of removing residual materials and ensuring separation effect.

[0025] Working principle: First, the wash pipe seat 2, serving as the basic installation carrier, is detachably fixed to the centrifuge product chamber door with bolts, providing stable support for the overall structure. At least two wash pipes 1 are installed parallel to each other inside the wash pipe seat 2. A ring pipe is welded between the wash pipes 1, connecting the wash pipes 1 into a whole along the circumference and assisting in the even distribution of the cleaning medium. The wash pipes 1 are spaced apart along the circumference of the ring pipe to expand the cleaning coverage area. When the cleaning position needs to be adjusted, loosen the adjusting nut 4 and the adjusting bolt 3, move the wash pipe 1 to the target position, and then tighten the adjusting bolt 3 so that it passes through the mounting hole of the wash pipe seat 2 and makes tight contact with the wash pipe 1 to achieve locking. Then, the adjusting nut 4 is used to press the outer wall of the wash pipe seat 2 to prevent loosening, ensuring the stability of the wash pipe 1 position. During cleaning, the medium enters the wash pipe 1 through the pipeline, is evenly distributed through the ring pipe, and is sprayed out from the nozzle of the wash pipe 1 to rinse the area to be cleaned inside the centrifuge product chamber. By using the fixed support of the washing pipe seat 2, the coordinated distribution of the washing pipe 1 and the annular pipe, and the position adjustment and locking functions of the adjusting bolt 3 and the adjusting nut 4, the problems of cleaning dead angles, incomplete cleaning or low efficiency caused by the inability of the traditional fixed cleaning pipe to adjust its position according to the production process in the background technology are solved. Dynamic adaptation of the cleaning position is achieved to ensure that the cleaning effect reaches the best under different process conditions.

[0026] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
