Description

Technical Field

[0001] This utility model relates to the field of horizontal screw centrifuge technology, specifically to a multi-section washing composite feed pipe for a horizontal screw centrifuge. Background Technology

[0002] A horizontal decanter centrifuge is a highly efficient centrifugal separation device. Its working principle involves a drum and a screw rotating at high speed in the same direction with a certain differential speed, separating materials. This equipment features a compact structure, continuous operation, stable operation, strong adaptability, large production capacity, and convenient maintenance. It is suitable for separating suspensions containing solid particles larger than 0.005mm and with a concentration range of 2-40%. Horizontal decanter centrifuges are widely used in chemical, light industrial, pharmaceutical, food, and environmental protection industries. Particularly in the environmental protection field, they are highly effective in sludge dewatering, helping to reduce sludge volume and facilitate subsequent processing.

[0003] For example, patent application CN202321468744.7, with authorization announcement date 20231121, describes a feed pipe structure for a horizontal screw centrifuge with washing and rinsing functions. The structure includes a feed pipe installed on the horizontal screw centrifuge, characterized by a rinsing section and a washing section mounted on the feed pipe. The rinsing section includes a rinsing outer pipe mounted on the feed pipe and a rinsing interface mounted on the rinsing outer pipe. The washing section includes a washing outer pipe mounted on the feed pipe and a washing interface mounted on the washing outer pipe. A partition separating the rinsing outer pipe and the washing outer pipe is also provided on the feed pipe. Through the rinsing section, rinsing water enters the rinsing chamber through the rinsing interface and is then sprayed out from the rinsing hole to clean the inside of the rotating drum. This achieves the function of cleaning the centrifuge, extending the service life of the equipment. Simultaneously, cleaning the rotating drum prevents material accumulation on it, thereby reducing operating noise and vibration, and further extending the equipment's service life.

[0004] While the feed pipe structure of commercially available horizontal screw centrifuges with washing functions can achieve the purpose of washing the feed pipe, it cannot clean the corresponding cavity inside the centrifuge during cleaning, resulting in poor cleaning effect. Therefore, there is an urgent need to design a multi-segment washing composite feed pipe for horizontal screw centrifuges to solve the above problems. Utility Model Content

Washing pipe 3 4 and washing pipe 1 2 are both bolted to the outer wall of the mounting flange 6. Washing pipe 2 3, washing pipe 3 4 and washing pipe 1 2 are all inserted into the support pipe 5. One end of washing pipe 2 3 is equipped with washing water inlet pipe 3 9 and washing water inlet pipe 1 7. When using the feed pipe 1, clean water can be injected into washing pipe 2 3, washing pipe 1 2 and washing pipe 3 4 through washing water inlet pipe 1 7, washing water inlet pipe 2 8 and washing water inlet pipe 3 9. Then the clean water will flow into washing pipe 2 3, washing pipe 1 2 and washing pipe 3 4 through the filter screen 12 and then spray out from the outlet 13 to carry out the washing work.

[0030] Example 2

[0031] This embodiment further defines the features of Embodiment 1. Multiple water outlets 13 are provided on one side of the outer wall of washing pipes 2 (3), 3 (4), and 1 (2).
