Description

Technical Field

[0001] This utility model relates to the field of potassium nitrate production technology, specifically to a drum screen recovery device used in potassium nitrate production. Background Technology

[0002] Potassium nitrate is an industrial material, an inorganic compound, also known as caustic soda. It is used in many industrial production processes such as agriculture, gunpowder, medicine, and glass, and is a very important industrial raw material. In its production process, it needs to be dried using a vibrating fluidized bed, and then screened using a drum screen. Unqualified large particles need to be sent to a remelting kettle to be dissolved with steam and then recrystallized and dried, which increases the production cost of enterprises.

[0003] As disclosed in CN218901953U, a rotary drum screen recovery device for potassium nitrate production includes a shell. A first crushing roller is rotatably connected to the top of the inner wall of the shell. A first motor is fixedly connected to the top of the outer side of the shell. A second crushing roller is arranged on one side of the first crushing roller. A filter screen is arranged in the middle of the inner wall of the shell. A second motor is fixedly connected to the top of the return cylinder. The output end of the second motor is fixedly connected to the top of the auger. The other end of the return pipe is located above the first crushing roller. In this invention, the potassium nitrate particles can be crushed by starting the first motor. Large potassium nitrate particles can enter the return cylinder through the filter screen. The potassium nitrate particles can be fed back into the shell for crushing by starting the second motor, ensuring that the final particles are all of the same size and avoiding reheating and crushing.

[0004] However, the existing technology CN218901953U describes a drum screen recycling device used in potassium nitrate production, which cannot achieve full automation in material recycling and processing, resulting in low working efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a rotary drum screen recovery device for potassium nitrate production, in order to solve the problem mentioned in the background art that the material recovery and processing cannot be fully automated and the working efficiency is low.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a box body, the top of which has a first sliding groove. A slider is movably connected inside the first sliding groove. A U-shaped baffle is fixedly connected to the top of the slider. An inclined plate is fixedly connected inside the U-shaped baffle. A first handle is fixedly connected to one end of the U-shaped baffle. Symmetrical inserts are fixedly connected to the other end away from the first handle. An inlet is opened at the end away from the U-shaped baffle. A vertical plate is fixedly connected to one end of the inlet. Symmetrical slots are opened at one end of the vertical plate. A recycling bin is fixedly connected to one end of the box body. A servo motor is fixedly connected to the top of the recycling bin. A lifting mechanism is movably connected to the output end of the servo motor. The lifting mechanism includes a movable lead screw, and a stabilizing rod is fixedly connected to the end away from the movable lead screw. The movable lead screw, the stabilizing rod, and the moving block are sleeved together. A mounting plate is fixedly connected to one end of the moving block.

[0007] Preferably, a mounting base is fixedly connected to the top of the mounting plate, a small rotating mechanism is fixedly connected to one end of the mounting base, a rotating rod is movably connected to the output end of the small rotating mechanism, and a recycling box is fixedly connected to the top of the rotating rod. By setting up the small rotating mechanism, the rotating rod and the recycling box, the small rotating mechanism drives the rotating rod to start rotating. As the rotating rod rotates, the recycling box begins to tilt towards the inlet, allowing the material inside to enter the inlet and be crushed again by the crushing roller, thereby achieving the purpose of conveying substandard materials. Preferably, a rotating mechanism is fixedly connected to one end of the housing, and a first rotating ring is movably connected to the output end of the rotating mechanism. The first rotating ring is sleeved with a belt, and the other end of the belt is sleeved with a second rotating ring. A fixing block is fixedly connected to one end of the second rotating ring, and a crushing drum is fixedly connected to the top of the second rotating ring. By setting up the rotating mechanism, the first rotating ring, and the belt, the operator starts the rotating mechanism through the control panel. The rotating mechanism drives the first rotating ring to rotate, and the first rotating ring drives the belt to start rotating. Under the action of the belt, the second rotating ring starts to rotate, and the first and second rotating rings drive the crushing drum to start rotating, thereby achieving the purpose of crushing materials. Preferably, the servo motor, the small rotating machine, and the control panel are electrically connected, and symmetrical control buttons are movably connected at both ends away from the control panel. By setting the control panel and control buttons, the operator can start and control the servo motor, the small rotating machine, and the rotating machine through the control panel and control buttons, thereby achieving the purpose of starting and controlling the servo motor, the small rotating machine, and the rotating machine. Preferably, an inclined chute and a second chute are respectively provided at the other end away from the turntable. A filter plate and a collection box are movably connected inside the inclined chute and the second chute, respectively. A second handle and a third handle are fixedly connected to one end of the filter plate and the collection box, respectively. By setting up the filter plate and the collection box, the processed material falls onto the filter plate, qualified material falls into the collection box through the filter plate, and unqualified material is transported to the recycling box above the filter plate, thereby achieving the purpose of filtering and collecting materials. Preferably, a standing platform is fixedly connected to one end of the box, an anti-slip mat is fixedly connected to the top of the standing platform, and symmetrical support rods are fixedly connected to the bottom of the standing platform and the box. Anti-slip sleeves are fixedly connected to the bottom of the support rods. By setting up the standing platform, anti-slip mat, support rods and anti-slip sleeves, the staff can place the device in the required position using the support rods, and the staff can stand on the standing platform to start working, thereby achieving the purpose of supporting the device and the staff.

[0008] Compared with the prior art, the beneficial effects of this utility model are: This rotary screen recovery device, applied to potassium nitrate production, features a control panel, control buttons, a servo motor, a small rotating mechanism, and a rotary drum. Operators activate the servo motor via the control panel, which drives a movable lead screw to rotate. As the lead screw rotates, a moving block moves the mounting plate upwards, which in turn moves the recovery box upwards until it leaves the recovery bin. Finally, operators activate the small rotating mechanism via the control panel, which drives a rotating rod to rotate. As the rotating rod rotates, the recovery box tilts towards the inlet, allowing the material to enter and be further crushed by the crushing drum. The processed material falls into a collection box, where operators pull the third handle to collect it. This fully automated material recovery process significantly improves the device's efficiency.

[0009] This rotary drum screen recovery device for potassium nitrate production features a removable filter plate. When the filter plate needs cleaning, the operator can simply pull it out of the inclined trough using the second handle. Installation is also straightforward; simply hold the second handle and align the filter plate with the inclined trough to install it, thus improving the device's practicality.
