Problems solved by technology

Due to the small vibration force generated by electromagnetic vibration or vibration motor, the current size of the existing vibrating screen is small, the efficiency of dehydration, desliming, and deintermediation is low, and the transmission speed is slow, resulting in low dehydration capacity and low screening efficiency. , low processing capacity, the maximum capacity of the existing dewatering screen can only reach 80 cubic meters per hour

Embodiment 1

[0032] refer to Figure 1 to Figure 2 , a double-shaft dewatering screen for a sand washing ship, comprising a dewatering screen frame 1, a dewatering screen 2, a first driving shaft assembly 3, a second driving shaft assembly 4 and a water tank 5, and a dewatering screen is installed in the middle of the dewatering screen frame 1 2. The mesh number of the dehydration screen 2 gradually increases from the inlet 121 to the outlet 122. The unique design of the dehydration screen 2 is adopted, and the mesh number of the dehydration screen 2 at the inlet 121 is small, which improves the water flow. Throughput, the dehydration screen 2 at the discharge port 122 has a larger mesh number, finely screens a small amount of water content in the sediment, improves the screening efficiency, and has a large filtration area. The top of the screen 2 is provided with a first drive shaft assembly 3 and a second drive shaft assembly 4, and the dehydration screen frame 1 includes a support colum...

Abstract

The invention discloses a sand washing boat dual-shaft dewatering screen and a method, and belongs to the technical field of dewatering screens. The dewatering screen comprises a dewatering screen shelf, a dewatering screen mesh, a first driving shaft assembly, a second driving shaft assembly and a water tank; the dewatering screen mesh is installed on the middle part of the dewatering screen shelf; the water tank is arranged at the lower end of the dewatering screen mesh; the first driving shaft assembly and the second driving shaft assembly are arranged above the dewatering screen mesh; thefirst driving shaft assembly comprises a main shaft, a driving motor, an eccentric wheel, an eccentric block, a sleeve and an installation plate; one end of the main shaft is connected with a motor shaft of the driving motor via a coupler and the other end is fixedly connected with the eccentric wheel which is in a semicircular shape; and the eccentric block is connected with the eccentric wheel in a fastening mode via a bolt. Vibration is realized by centrifugal force generated by rotation of the eccentric wheel, the vibration amplitude is large, operation is stable, noises are low, screeningefficiency is improved, and the filtering area is large.

Description

technical field [0001] The invention relates to the technical field of dewatering screens, in particular to a double-shaft dewatering screen for sand washing ships and a method thereof. Background technique [0002] The stones in the sand making plant are crushed and screened to make sand. Raw stones are mixed with mud or other media, and they are washed with water during crushing and screening. At this time, the sand contains a large amount of mud, water and other media, which must be dehydrated, deslimed, and de-mediumed to meet the requirements of the finished sand, and whether the dehydration, de-slimed, and de-mediumed is clean determines the grade of the sand. On the other hand, the efficiency and production capacity of the dewatering screen are also required to be as high as possible. [0003] Patent No. CN201820137332.8 provides a dual-axis dewatering screen, including a bottom plate and a dewatering screen box, the front end of the bottom plate is connected to the...
