Description

Technical Field

[0001] The utility model relates to the technical field of drum screens, in particular to a drum screen for the production of amino acid organic fertilizers. Background Technique

[0002] An amino acid is a compound in which a hydrogen atom on the carbon atom of a carboxylic acid is replaced by an amino group. An amino acid molecule contains two functional groups, an amino group and a carboxyl group. Amino acids are the basic substances that make up proteins required for animal nutrition and are extremely widely used. Therefore, the preparation of amino acids and their related products is very important. The preparation process of amino acid organic fertilizers includes multiple stages and processes. Among them, screening is an indispensable process, and a drum screen is the most common screening device.

[0003] A drum screen with the publication number of CN222057977U includes a drum screen body and a conveying component. The conveying component includes a working frame, two guide rail frames, two rolling rollers, an electric conveyor belt, a funnel, a connecting pipe, a hollow column, a bearing seat, a rotating shaft and a fixed seat. The other end of the connecting pipe is communicated with the funnel. The rotating shaft is fixedly connected to the drum screen body. The fixed seat is fixedly connected to the working frame. The rotating shaft is rotatably connected to the fixed seat. Start the electric conveyor belt to move the fly ash into the funnel, and then discharge it into the drum screen body through the connecting pipe. Then rotate the drum screen body to make the hollow column and the rotating shaft rotate in the corresponding bearing seat and fixed seat to screen the fly ash. By this way, it is to avoid manual feeding by staff, which can effectively reduce the fatigue intensity of the staff, improve the efficiency and quality of screening fly ash, and facilitate subsequent processing and use. However, the bottom of the conical bin shrinks too quickly, the cross-sectional area of the material flow suddenly decreases, which intensifies the extrusion and friction between particles, thus easily leading to the concentrated accumulation and blockage of materials, affecting the feeding rate, and then affecting the processing efficiency.

Detailed implementation manners

[0020] The technical solutions in the embodiments of the present invention will be further described below with reference to the drawings and embodiments.

[0021] As Figures 1 - 4 shown, the embodiments of the present invention propose a drum screen for producing amino acid organic fertilizer, including:

[0022] Support frame 1, on which two fixed rings 2 are fixedly connected. Between the two fixed rings 2, a drum screen body 3 is rotatably connected. The drum screen body 3 is a prior art and is composed of a screen cylinder and a screen mesh. The screen mesh is arranged on the side wall of the screen cylinder. When rotating, it realizes the screening of materials, which will not be elaborated here. On the support frame 1, a feeding component and two driving components are installed. The feeding component includes two vertical frames 4 fixedly connected to the upper end face of the support frame 1. Between the two vertical frames 4, a vibrating frame 5 is slidably connected. On the vibrating frame 5, a storage hopper 6 is fixedly connected. A discharge pipe 7 is communicated with the storage hopper 6. The inner wall of the storage hopper 6 is inclined, which is convenient for the materials in the storage hopper 6 to be discharged through the discharge pipe 7. A funnel 18 is fixedly connected to the upper end face of the storage hopper 6, which is convenient for materials to be added into the storage hopper 6. A ring-shaped pulley 8 is fixedly connected to the drum screen body 3. A driven pulley 9 is rotatably connected to the support frame 1. The ring-shaped pulley 8 and the driven pulley 9 are driven by a transmission belt 10. A rotating rod 11 is rotatably connected to the support frame 1. The rotating rod 11 is fixedly connected to the driven pulley 9. An elliptical plate 12 is fixedly connected to the rotating rod 11. A plurality of springs 13 are fixedly connected to the two vertical frames 4. The plurality of springs 13 are all fixedly connected to the vibrating frame 5. A support rod 14 is fixedly connected to the lower end face of the vibrating frame 5. The elliptical plate 12 is attached to the support rod 14;

[0023] The driving component includes a roller ring 15 fixedly connected to the side wall of the drum screen body 3. A motor 16 is fixedly installed on the support frame 1. A friction roller 17 is rotatably connected to the support frame 1. The rotating end of the motor 16 is fixedly connected to the friction roller 17. The friction roller 17 is attached to the roller ring 15. Anti-slip patterns are provided on the outer wall of the roller ring 15 and the lower end face of the support frame 1, which improves the friction between the roller ring 15 and the friction roller 17, making the drum screen body 3 rotate stably. The anti-slip patterns of the support frame 1 improve the stability of the device. The roller ring 15 generates friction by contacting the friction roller 17, driving the drum screen body 3 to perform a rotational motion. Its rotational motion principle is similar to that of a shaftless drum screen. The rotation principle of the shaftless drum screen is a prior art. The specific method is that the shaftless drum screen drives the supporting roller to rotate through a driving device, and friction is generated between the supporting roller and the drum, so that the drum starts to rotate. This design not only simplifies the structure, reduces the maintenance cost, but also improves the durability and operation stability of the equipment, which will not be elaborated here. A plurality of inclined guide plates 19 are fixedly connected to the inner wall of the drum screen body 3, so as to realize the blocking of materials, extend the residence time of the materials in the drum screen body 3, and ensure the screening quality;

[0024] Above the funnel 18, there is an inclined belt conveyor 20. The inclined belt conveyor 20 is an existing technology, which is composed of a driving device, a redirecting roller, an endless conveyor belt, load-carrying rollers, return rollers, a tensioning device, a frame and a protective device. Its working principle is that the driving device drives the head driving roller to rotate through a reducer, and uses the friction between the roller and the conveyor belt to traction the belt to circulate. The inclined frame enables the material to be conveyed from the low-position feeding end to the high-position discharging end. The load-carrying section is supported by troughing rollers to form a trough to prevent the material from spilling. The return section is supported by flat rollers to carry the empty conveyor belt. The tensioning device maintains the belt tension. Anti-slip patterns or brakes are equipped under special inclination conditions to prevent the material from sliding back, so as to complete the conveying of fertilizers, which will not be elaborated here.

[0025] The detailed working process of the present utility model is as follows:

[0026] The inclined belt conveyor 20 sends the fertilizer to the funnel 18. The fertilizer enters the storage hopper 6 through the funnel 18. Subsequently, the motor 16 starts to work, and the friction roller 17 rotates. Under the action of friction, the roller ring 15 rotates, so that the drum screen body 3 rotates. Subsequently, under the cooperation of the annular pulley 8, the driven pulley 9 and the transmission belt 10, the elliptical plate 12 rotates and impacts the support rod 14. Under the limit of the spring 13, the storage hopper 6 can vibrate up and down, making the material present a loose flow state, realizing continuous and uniform discharging output, reducing the accumulation or intermittent problem of the material at the discharging port, and facilitating the material to be discharged from the discharging pipe 7. When the material enters the drum screen body 3, the screened material is discharged from the side wall of the drum screen body 3. The inclined drum screen body 3 enables the waste material to be discharged from the other end of the drum screen body 3, without the need for the staff to stop the machine for cleaning, ensuring the screening efficiency.
