Improvement of stainless steel strip welding sieve plate for coal preparation equipment
Aiming at the important parts of the stainless steel strip welding sieve plate for coal preparation equipment,the problem of sieve hole blockage and frame rib plate fracture often occurs in the actual use process.Adopting the method of specific problem analysis,on the one hand,the upper layer of the sieve plate is arranged in a positive trapezoidal way according to the radial section,and the lower layer is arranged in an inverted trapezoidal way according to the radial section,to ensure that the materials entering the sieve hole can pass through the sieve hole without obstruction,become the material through the sieve,and avoid the blockage on the sieve hole;on the other hand,the alloy structure steel with better mechanical performance is adopted to improve the material of the fixed seat of the sieve plate and the frame rib plate,to solve the problem of the fracture of the frame and the rib plate,and prolong the service life of the sieve plate.The experimental test results show that the sieve plate with the new structure has been effectively solved the problem of blocking the hole,and the service life has been improved.
