Description

Multistage sorting screening and collecting device Technical Field The utility model relates to the technical field of spray dryer equipment, in particular to a multistage screening and receiving device for a spray dryer. Background The spray drying technology is used as a high-efficiency continuous drying method and is widely applied to the drying treatment of various liquid materials. However, conventional spray dryers typically require a transfer step to screen the material after drying is completed to separate out particles of different sizes, which not only increases the complexity of the production process but may also result in contamination or loss of the material during transfer. The prior spray dryer such as China patent (application number: 202222564846.0) discloses a spray dryer with a grading function, which comprises a dryer body and a supporting plate, wherein the supporting plate is arranged on the surface of the dryer body, two vertical plates are arranged on the left side and the right side of the bottom of the supporting plate respectively, the mounting plates are arranged on the bottoms of the two vertical plates, the grading and screening mechanism is arranged on the top of the mounting plates and comprises a movable shell and a connecting plate, and the movable shell is arranged on the top of the mounting plates. According to the utility model, the movable shell, the screen, the top block, the connecting plate, the servo motor, the lug, the movable block, the fixed rod, the movable plate and the spring are mutually matched, so that the grading screening effect can be realized, the materials with different sizes are screened out, the screening effect is improved, the screen can be disassembled and replaced according to the requirement in the later stage, the screen with the required aperture can be conveniently replaced, and the applicability is improved. The device has the screening function after drying, but does not disclose the collection of materials, and the materials after screening still need to be transported during conveying and collection, thus not effectively improving the production efficiency Disclosure of utility model In order to solve the problems, the embodiment of the utility model provides a multi-stage material screening and collecting device capable of directly screening materials after drying. The embodiment of the utility model aims to achieve the aim, and particularly adopts the following technical scheme that the multistage material separating, screening and collecting device comprises a receiving material cylinder arranged at the lower part of a spray dryer, wherein a first material receiving pipe is arranged at the upper part of the receiving material cylinder, a second material receiving pipe is arranged at the lower part of the receiving material cylinder, and a screening mechanism for screening materials is arranged at the middle part of the receiving material cylinder. As a further improvement of the above technical scheme: The screening mechanism comprises a screen plate arranged below the first receiving pipe, and a vibrating block is arranged on the screen plate. The sieve slope sets up and outwards extends from the one end that is close to first receipts material pipe, and the level increases gradually. The sieve is provided with the braced frame who is connected with the inside wall of accepting the feed cylinder all around, be provided with the transmission shaft that runs through the vibrating mass on the braced frame, the one end of transmission shaft extends to the outside of accepting the feed cylinder and is provided with the actuating source. The feeding end of the first receiving pipe is provided with a screen, and a blanking gap is arranged between one end of the supporting frame, which faces the first receiving pipe, and the side wall of the receiving material barrel. The top of first receipts material pipe is provided with the striker plate, the one end of striker plate is connected with the inside wall of accepting the feed cylinder, and the other end extends to the top of sieve. The multi-stage material separating, screening and collecting device has the advantages that the multi-stage material separating, screening and collecting device comprises the receiving material cylinder arranged at the lower part of the spray dryer, the first receiving material pipe is arranged at the upper part of the receiving material cylinder, the second receiving material pipe is arranged at the lower part of the receiving material cylinder, the screening mechanism for screening materials is arranged at the middle part of the receiving material cylinder, the materials are screened in the receiving material cylinder through the screening mechanism, and then are conveyed and stored in a grading manner through the first receiving opening and the second receiving opening.
