Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer anti-clogging screening, and in particular to a compound fertilizer anti-clogging screening device. Background Technology

[0002] In the process of producing compound fertilizer, it is necessary to screen it. However, due to different batches, some batches of fertilizer may not be dried enough or may have absorbed external moisture over time. During the stacking process, they may be squeezed together and become sticky. Therefore, they are prone to clogging in the subsequent screening process. Workers need to constantly pry and manually pick up the knotted parts and crush them for screening, which is very troublesome. Therefore, based on this technical problem, we designed a compound fertilizer anti-clogging screening device. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a compound fertilizer anti-clogging screening device, including a support platform, a screen frame, a vibrating frame, and a mixing and drying tank; the support platform has a vibrating frame in the middle, and multiple vibrating springs are arranged in a circular array around the vibrating frame. A polarization motor is installed inside the vibrating frame. A screen base groove is installed above the vibrating springs. The structure of the screen base groove is exactly the same as that of the screen frame. The main body of the screen frame and the screen base groove is a circular groove structure. A first discharge port is provided on one side of the screen frame and the screen base groove. A sealed plate is provided at the bottom of the screen base groove. A screen is provided at the bottom of the screen frame. More than one screen frame can be stacked on top of the screen base groove. A mixing and drying tank is provided above the screen base groove. A support frame is arranged around the mixing and drying tank and the support frame is fixed to the support platform. A second discharge port is provided at the bottom of the mixing and drying tank. A mixing device and a drying device are installed inside the mixing and drying tank.

[0004] The lower side of the mixing and drying tank is funnel-shaped, converging towards the center.

[0005] The second discharge port is equipped with a solenoid valve.

[0006] The stirring device includes a stirring rod, a stirring motor, and stirring blades. The stirring motor is located above the stirring rod, and the stirring rod has one or more stirring blades arranged in a circular array. The stirring blades are in contact with the stirring and drying tank.

[0007] The drying device includes warm air branch pipes, warm air outlets, a main warm air pipe, a heating pipe, a heating resistance wire, and a fan. Multiple warm air outlets are evenly arranged on the lower side of the mixing drying tank. Each warm air outlet is connected to a warm air branch pipe. Multiple warm air branch pipes on both sides are connected to a main warm air pipe. The main warm air pipes on both sides are connected to the heating pipe in the middle. A heating resistance wire is installed inside the heating pipe. A fan is installed on the other side of the heating pipe. The fan blows heated warm air into the mixing drying tank through the warm air outlets for drying.

[0008] The screen base groove is provided with multiple pins around its top perimeter, and the vibrating frame is provided with corresponding insertion holes below it. The vibrating frame is provided with multiple pins at positions corresponding to the pins in the screen base groove, and they are stacked by the cooperation of the pins and insertion holes.

[0009] The beneficial effects of this utility model are as follows:

[0010] This device stacks multiple screen frames according to screening needs. The bottom screen base trough does not require screening, so it does not have a sealed screen structure. When the material is put into the mixing and drying tank, the mixing motor is started to drive the mixing rod to rotate. The mixing blades on the mixing rod cause the material to tumble, breaking up any sticky material. At the same time, the warm air outlet continuously blows out warm air to dry the material, further facilitating the breaking up of the material. This achieves the effects of drying and preventing clogging. Attached Figure Description
