Description

Technical Field

[0001] This utility model relates to the technical field of equipment for sodium bicarbonate production, and in particular to an online cleaning device for circulating liquid filtration in sodium bicarbonate production. Background Technology

[0002] In the production of baking soda, the purification of circulating water is mainly achieved through a circulating water filtration system. This system uses multiple high-efficiency suspended extruded fiber filters connected in parallel to treat the circulating water. This filter is a deep-bed fiber filter, requiring the incoming water to have a suspended solids content <15mg / L and a suspended solids particle size >1μm. After treatment, the suspended solids content in the water should be below 1.5mg / L.

[0003] Patent application CN212881289U discloses an online cleaning device for circulating liquid filtration in sodium bicarbonate production, including an inlet pipe, with distribution pipes equidistantly connected to the front of the inlet pipe, a filter sleeve connected to one end of the distribution pipe, and an outlet pipe connected to the lower front side of the filter sleeve via an external drain pipe.

[0004] In this device, the pusher plate can push the internal impurities upwards to the top of the filter screen sleeve. At this time, the internal impurities can enter the collection sleeve. This operation method avoids manual disassembly and cleaning, is simple and fast, and can be cleaned online in real time. However, the filter screen of this device is not convenient to disassemble quickly. Because some impurities are squeezed into the filter screen with each pusher plate operation, these impurities will accumulate over time and cause the filter screen to become clogged, thereby affecting the normal operation of the equipment and the filtration efficiency. To address the above problems, we have launched an online cleaning device for circulating liquid filtration in sodium bicarbonate production. Utility Model Content

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] The online cleaning device for circulating liquid filtration in baking soda production disclosed in this utility model is mainly applied to equipment used in baking soda production.

[0023] Reference Figures 1 to 5A circulating liquid filtration online cleaning device for baking soda production includes: an inlet pipe 1, an outlet pipe 2 at the bottom of the inlet pipe 1, a filter sleeve 3 on one side of the inlet pipe 1, an installation plate 6 inside the filter sleeve 3, a fixing rod 7 fixedly connected at equal intervals between the outer side of the installation plate 6 and the inside of the filter sleeve 3, a filter screen 8 at the top of the installation plate 6, a first connecting pipe 4 between the outer side of the inlet pipe 1 and the inside of the filter screen 8, a second connecting pipe 5 between the filter sleeve 3 and the outer side of the outlet pipe 2, an installation component at the top of the installation plate 6, and a pushing component at the bottom of the filter sleeve 3.

[0024] The mounting assembly includes a mounting block 9, which is fixedly connected to the top of the mounting plate 6. A slide rod 10 is slidably connected between the mounting block 9 and the inside of the filter sleeve 3. A clamping plate 11 is fixedly connected to one end of the slide rod 10, and the inside of the clamping plate 11 abuts against the outside of the filter screen 8.

[0025] A connecting rod 14 is fixedly connected between one side of the mounting block 9 and the inner wall of the filter sleeve 3. A connecting plate 15 is fixedly connected to the outer side of the slide rod 10. The inside of the connecting plate 15 is slidably connected to the outside of the connecting rod 14. A spring 13 is provided on the outside of the slide rod 10.

[0026] Two collars 12 are provided on the outer side of the filter screen 8, and an anti-slip pad is provided inside the clamping plate 11.

[0027] In the above technical solution, considering that the filter screen of the device is inconvenient to disassemble quickly, and that some impurities are squeezed into the filter screen during each push operation, these impurities will accumulate over time and cause the filter screen to become clogged, thus affecting the normal operation and filtration efficiency of the equipment, the specific operation is as follows: By setting up the installation component, during installation, the slide rod 10 is pulled open so that the clamping plate 11 is separated to the maximum distance. At this time, the spring 13 will be compressed. Then the filter screen 8 is placed on the mounting plate 6, and the vertical rod 16 extends through the mounting plate 6 to the bottom of the filter sleeve 3. Then the slide rod 10 is released, and under the action of the spring 13, the clamping plate 11 is pressed against the middle of the filter screen 8 and locked between the two collars 12. Then the vertical rod 16 is fixed to the push component. When the filter screen 8 becomes clogged, the slide rod 10 is pulled again, and the clamping plate 11 is moved so that the clamping plate 11 is separated from the filter screen 8 and staggered from the collars 12. The filter screen 8 can then be taken out from the top of the filter sleeve 3 for rinsing or replacement. This design avoids the cumbersome process of disassembling the entire unit required by traditional filters, saving time and labor costs and ensuring that filter 8 always remains in good working order. This will improve filtration efficiency and reduce downtime caused by clogging.

[0028] Reference Figures 1 to 5In a preferred embodiment, the pushing component includes a vertical rod 16, which is slidably connected inside the filter sleeve 3. The top of the vertical rod 16 extends into the interior of the filter screen 8 and is fixedly connected to a pusher plate 17. The bottom of the filter sleeve 3 is fixedly connected to a mounting bracket 18, and the top of the mounting bracket 18 is provided with a telescopic rod 19. The top of the telescopic rod 19 abuts against the bottom of the vertical rod 16, and the telescopic rod 19 and the vertical rod 16 are installed by bolts. The bottom of the vertical rod 16 and the top of the telescopic rod 19 are fixed by bolts, and then the telescopic rod 19 is activated to extend upward, thereby driving the vertical rod 16 and the pusher plate 17 to move upward, and the pusher plate 17 pushes out the impurities inside the filter screen 8.

[0029] Reference Figures 1 to 5 In a preferred embodiment, a placement plate 20 is fixedly connected inside the filter sleeve 3, and a collection frame 21 is slidably connected inside the filter sleeve 3. The bottom of the collection frame 21 abuts against the top of the placement plate 20. By setting the collection frame 21, the pushed-out impurities can fall into the collection frame 21 for collection. This operation method avoids manual disassembly and cleaning, is simple and fast, and can be cleaned online in real time.

[0030] Working principle: During installation, pull the slide rod 10 to separate the clamping plate 11 to its maximum distance. At this time, the spring 13 will be compressed. Then, place the filter screen 8 on the mounting plate 6. The vertical rod 16 extends through the mounting plate 6 to the bottom of the filter sleeve 3. Then, release the slide rod 10. Under the action of the spring 13, the clamping plate 11 will abut against the middle of the filter screen 8 and be locked between the two collars 12. Then, fix the vertical rod 16 to the pushing assembly. When the filter screen 8 becomes clogged, pull the slide rod 10 again and move the clamping plate 11 so that the clamping plate 11 separates from the filter screen 8 and is offset from the collars 12. The filter screen 8 can then be removed from the top of the filter sleeve 3 for rinsing or replacement. All contents not described in detail in this manual are existing technologies known to those skilled in the art.
