Description
Technical Field
[0001] This utility model relates to the field of dewatering screen technology, specifically a rapid drainage structure for a dewatering screen. Background Technology
[0002] The dewatering screen employs dual-electrode self-synchronization technology, a universal eccentric block, and adjustable amplitude. It mainly consists of a screen box, a support system, and a motor. Two independent vibrators are driven synchronously in opposite directions via a belt coupling. The centrifugal forces generated by the two sets of eccentric masses are superimposed along the vibration direction, while the opposing centrifugal forces cancel each other out, thus forming a single excitation vibration along the vibration direction, causing the screen box to perform reciprocating linear motion. Its main functions are dewatering, desliming, and demediuming. It can be used in sand and gravel plants, recycling, etc., and is therefore also called a sand and gravel dewatering screen, mining dewatering screen, coal slime dewatering screen, and dewatering screen, etc.
[0003] Chinese Utility Model Patent Publication No. CN221358830U discloses a rapid drainage structure for a coal dewatering screen. This rapid drainage structure uses a cleaning brush and a screw assembly to continuously clean the screen, preventing clogging and ensuring the dewatering effect is not affected. This allows for rapid drainage, resulting in fully dewatered coal at the feed inlet, avoiding secondary dewatering operations. This saves considerable time, reduces labor intensity, and improves work efficiency. However, while this rapid drainage structure achieves rapid drainage, it is not suitable for separating and discharging mud and sand mixtures, requiring subsequent secondary separation, thus reducing its practicality. Summary of the Invention

[0011] Through the above technical solution, and through the design of the discharge pipe one, when the sand and gravel are full, they can be discharged through the discharge pipe one, which facilitates the processing and discharge of the sand and gravel in the first collection box.
[0012] Preferably, there are two identical collection troughs, through troughs, first collection boxes, and discharge pipes, and the two collection troughs, through troughs, first collection boxes, and discharge pipes are symmetrically distributed about the center line of the dewatering screen body.
[0013] The above technical solution, through the design of two collection tanks, a through trough, a first collection box and a discharge pipe, can increase the processing capacity of the drainage box and its storage capacity. Furthermore, both can be processed separately, which can improve its practicality.
[0014] Preferably, the end of the second collection box away from the dewatering screen body is designed as an "inclined" shape, and a feeding chute is provided at the end of the second collection box away from the dewatering screen body.
[0015] Through the above technical solution, and through the design of the second collection box, water can flow from the first collection box into the second collection box through overflow, and then the water in the second collection box can be discharged through the discharge chute.
[0016] Preferably, the second collection box is provided with a second discharge pipe through a discharge chute, and both the first discharge pipe and the second discharge pipe are provided with a solenoid valve at the other end away from the dewatering screen body.
[0017] Through the above technical solution and the design of the solenoid valve, it is easy to control the remaining amount of sand or water in the first and second collection tanks, and it is easy to empty the first and second collection tanks.

With the design of the through groove, excess water can overflow into the second collection box, which can separate the sand and gravel from the water source. No secondary treatment is required, which can improve work efficiency and facilitate subsequent processing.
