TECHNICAL FIELD

[0001] The utility model relates to a screening device field, concretely relates to a screening device for screening molecular sieve. BACKGROUND

[0002] The screening of molecular sieve is generally carried out through a vibrating screen, and the vibrating screen generally adopts a multistage vibrating screen to screen the molecular sieve after granulation into different size grades. Due to different use places, the size grades of the molecular sieve are divided into many kinds, and the screen plate of the existing vibrating screen is generally fixedly welded on the frame, so that many vibrating screens with different screening grades are required to cope with the screening requirements of the molecular sieve with different size grades. This results in an increase in cost, and the equipment also needs to be specially placed. Therefore, a screening device for molecular sieve, which can conveniently dismount and replace the screen plate, is required. SUMMARY

[0003] The utility model aims at providing a screening device for screening molecular sieve to solve the technical problem of high cost caused by the fact that the screen plate of the molecular sieve cannot be dismounted and replaced in the prior art.

[0005] The distance between the left side plate and the right side plate is less than the length of the front and rear side plates along the left-right direction, so that the left side of the frame has a left vertical slot with a left opening, and the right side of the frame has a right vertical slot with a right opening; the screen plate fixing structure comprises a left fixing bolt in the left vertical slot and a right fixing bolt in the right vertical slot.

[0006] The front groove wall of each vertical slot is provided with a first mounting plate at each through hole, and the rear groove wall is provided with a second mounting plate at each through hole, and the left fixing bolt and the right fixing bolt are installed on the corresponding mounting plate.

[0007] Each through hole is covered with a sealing strip, and the inner side of the sealing strip is flush with the inner side of each side plate.

[0008] Each of the sieve plates is inclined, and the molecular sieve outlet is located at the lower end of each sieve plate.

[0009] A positioning baffle is provided on one side of the frame along the left-right direction to position and stop the sieve plate that is inserted into the corresponding insertion hole.

[0010] The beneficial effects of this invention are as follows: The sieve plate fixing structure can fix the sieve plate and reduce the gap between the sieve plate and the upper wall of the corresponding through hole. The sieve plate fixing structure also allows the sieve plate to be loosened, allowing it to be pulled directly out of the through hole and replaced with a new sieve plate. After replacement, the sieve plate can be fixed again using the fixing structure. The screening equipment of this invention makes sieve plate replacement very convenient, requiring only one set of screening equipment and multiple sieve plates of different sizes and grades, making it particularly suitable for small enterprises. Compared with existing technologies, it can significantly reduce the production costs caused by the large variety of screening equipment sizes in the molecular sieve production process.
