Description

Technical Field

[0001] This utility model relates to the technical field of washing liquid distributors, specifically to a tubular washing liquid distributor device for alumina filters. Background Technology

[0002] The washing liquid distributor is the core component of the rotary vacuum filter. The rotary vacuum filter for alumina is mainly used for filtering mixtures of aluminum hydroxide and sodium aluminate. The washing water in the washing water distributor is an alkaline solution with a temperature of about 105°C. Uneven washing water will directly affect the quality of the filtered aluminum hydroxide solid.

[0003] Current washing liquid distributors cannot control the amount of washing water, meaning the nozzle opening size cannot be adjusted, the water distribution is uneven, the spray direction may be inconsistent, the nozzles are difficult to clean due to scale buildup, and the nozzles use threaded connections, making disassembly and replacement cumbersome and costly.

[0006] This utility model provides a tubular washing liquid distributor device for alumina filters, including a support and a main pipe; the main pipe is connected to the support, and flange covers are installed at both ends of the main pipe. The flange covers are fixedly connected to the main pipe by flange fasteners. The top of the main pipe is provided with a water inlet, and the bottom is provided with multiple branch pipes. Each branch pipe is connected to a nozzle body at its bottom. The nozzle body is connected to the branch pipe by a clamp structure. The nozzle body has an opening on its pipe wall, and the bottom of the nozzle body is provided with an adjusting piston. The adjusting piston is detachably connected to the nozzle body by threads.

[0007] Furthermore, the clamp structure includes a clamp, two clamp joints, and a sealing ring; one clamp joint is welded to the branch pipe, and the other clamp joint is welded to the top of the nozzle body. The sealing ring is installed between the two clamp joints, and the clamp clamps the two clamp joints, thereby connecting the nozzle body to the branch pipe.

[0008] Furthermore, the opening angle of the opening is 180°.

[0009] Furthermore, an F4 sealing gasket is provided between the flange cover and the main pipe.

[0010] Furthermore, an O-ring is provided between the nozzle body and the adjusting piston.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) This utility model has multiple branch pipes on the main pipe, and each branch pipe is connected to a nozzle body, which results in a small amount of washing water and uniform spraying of washing water.

[0014] (2) The nozzle body and the branch pipe of this utility model are connected by a clamp structure. The nozzle body can be rotated by loosening the clamp, which makes it easy to adjust the spraying direction of the nozzle body. The nozzle body can be quickly cleaned and replaced by disassembling the clamp structure.

[0015] (3) The present invention has an adjusting piston below the nozzle body. The adjusting piston can be adjusted up and down by rotating the screw thread.

Detailed Implementation

[0021] To provide a more detailed understanding of the features and technical content of this utility model, the implementation of this utility model will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit this utility model.

[0022] like Figure 1-4As shown, a tubular washing liquid distributor device for alumina filters includes a support 1 and a main pipe 6. The main pipe 6 is connected to the support 1. Flange covers 3 are installed at both ends of the main pipe 6. The flange covers 3 are fixedly connected to the main pipe 6 by flange fasteners 5. The top of the main pipe 6 is provided with a water inlet 2, and the bottom is provided with multiple branch pipes 7. Each branch pipe 7 is connected to a nozzle body 11 at its bottom. The nozzle body 11 is connected to the branch pipe 7 by a clamp structure. The nozzle body 11 has an opening 14 on its pipe wall. The opening angle of the opening 14 is 180°. The bottom of the nozzle body 11 is provided with an adjusting piston 12. The adjusting piston 12 is detachably connected to the nozzle body 11 by threads.

[0023] The position of the adjusting piston 12 is adjusted by means of a thread, and the top of the adjusting piston 12 can move up and down at the opening 14 to adjust the amount of water output.

[0024] The clamp structure includes a clamp 10, two clamp joints 8, and a sealing ring 9; one clamp joint 8 is welded to the branch pipe 7, and the other clamp joint 8 is welded to the top of the nozzle body 11. The sealing ring 9 is installed between the two clamp joints 8, and the clamp 10 clamps the two clamp joints 8, so that the nozzle body 11 is connected to the branch pipe 7.

[0025] An F4 sealing gasket 4 is also provided between the flange cover 3 and the main pipe 6 to increase the sealing performance of the main pipe 6. The two ends of the main pipe 6 are connected to form a closed washing liquid channel through the flange cover 3, the F4 sealing gasket 4, and the flange fastener 5.

[0026] An O-ring 13 is also provided between the nozzle body 11 and the adjusting piston 12 to effectively seal the bottom of the nozzle body 22.

[0027] The nozzle body 22 has a groove 15 at its lower part, and a small hole 16 is provided in the groove 15. The small hole 16 is used to discharge the washing liquid between the nozzle body 11 and the adjusting piston 12, so as to prevent the sealed space from affecting the adjustment of the adjusting piston 12.

[0028] Working principle: Alkaline washing solution enters the main pipe 6 through the inlet 2 on the main pipe 6, and is sprayed through the nozzle bodies 11 on multiple branch pipes 7. By loosening the clamp 10 and rotating the nozzle body 11, the openings 14 on the multiple nozzle bodies 11 are aligned in the same direction, and the spraying direction of the multiple nozzle bodies 11 is consistent, forming a complete water curtain to thoroughly wash the filtered material. When it is necessary to clean the inside of the main pipe 6, the flange fasteners 5, flange covers 3 and F4 sealing rings 4 at both ends of the main pipe 6 can be removed.

[0029] This invention features multiple branch pipes 7 on the main pipe 6, each branch pipe 7 connected to a nozzle body 11, resulting in a small water volume and even water spraying. The nozzle body 11 is connected to the branch pipes 7 via a clamp structure; loosening the clamp allows rotation of the nozzle body 11, facilitating adjustment of the spray direction. Removing the clamp allows for quick cleaning and replacement of worn or clogged nozzle bodies 11. An adjusting piston 12 is located below the nozzle body 11; adjusting the piston 12 up and down via screw rotation blocks a portion of the opening 14, thus adjusting the water flow rate. This simple and convenient operation allows for easy water flow adjustment.

[0030] Here, the specific models of the devices mentioned above are not limited or described in detail, and the in-depth connection methods of the devices mentioned above are not described in detail, as they are common knowledge and can be understood by those skilled in the art.

[0031] This utility model embodiment is merely an illustration of its specific implementation and is not intended to limit its scope of protection. Those skilled in the art can make certain modifications based on this embodiment; therefore, all equivalent changes or modifications made in accordance with the scope of this utility model patent claim fall within the scope of this utility model patent claim.
