Description

Technical Field

[0001] This utility model relates to the field of vibrating screen discharge technology, specifically to a multi-level vibrating screen discharge port structure. Background Technology

[0002] Multi-stage vibrating screens are high-efficiency grading and screening equipment. Through the stacked design of multiple screen layers, they achieve multi-stage separation of materials. The excitation force generated by the vibrating motor causes the screen box to vibrate at high frequency, causing the material to jump and advance on the screen surface. Particles of different sizes are accurately graded through the corresponding apertures of each screen layer. They can be widely used in mining, metallurgy, building materials, chemical and other industries. By adjusting the vibration frequency and amplitude parameters, they can adapt to the screening needs of materials with different specific gravities and viscosities. The discharge port of the multi-stage vibrating screen is the main component for grading and outputting materials according to different particle sizes. In traditional multi-stage vibrating screens, the distance between the discharge ports is small. Material particles output from the discharge ports mix with other particles of different sizes after collision and splashing, resulting in impurities of different particle sizes within the output particles of the corresponding size, affecting the output efficiency of the multi-stage vibrating screen. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage vibrating screen discharge port structure, including a main housing, the main housing being inclined, and a first auxiliary housing, a second auxiliary housing, and a third auxiliary housing arranged sequentially from high to low above the main housing. A partition is horizontally arranged in the middle of the interior of each of the first, second, and third auxiliary housings.

The upper end of the main box has a main inlet corresponding to the main discharge pipe, and the upper end of the main box has an auxiliary inlet corresponding to the auxiliary discharge pipe. Inside the main box, there is a discharge partition between the main inlet and the auxiliary inlet. The middle of the lower end of the main box is connected to a main output pipe, and the front and rear sides of the lower end of the main box are connected to auxiliary output pipes.

[0005] Preferably, the interior of the main housing is divided into a main discharge chamber in the middle and auxiliary discharge chambers on the front and rear sides by the discharge partition. There are two auxiliary discharge chambers. The upper end of the main discharge chamber is connected to the main receiving port, and the lower end of the main discharge chamber is connected to the main output pipe. The upper end of the auxiliary discharge chamber is connected to the auxiliary receiving port, and the lower end of the auxiliary discharge chamber is connected to the auxiliary output pipe.

The main cavity is connected to the main discharge pipe, and the auxiliary cavity is connected to the auxiliary discharge pipe.

[0007] Preferably, the main discharge pipe is connected to the main housing via a splice connection with the main receiving port.
