Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, specifically to a rotary drum screen. Background Technology

[0002] The rotary drum screen mainly consists of a drum body, supporting rollers, a transmission device, a protective cover, and a water spray system. The drum body can be tilted 1°-10° on the front and rear supporting rollers. The screen plate holes are arranged from largest to smallest from the feed end to allow the slurry to enter the slurry tank quickly, reducing the load on the drum body. Additionally, a certain number of lifting plates, inclined braces, and partition plates are evenly distributed inside the drum body to support and reinforce it, greatly reducing deformation during operation. The gear transmission system uses an integrated gear structure, reducing equipment installation and subsequent maintenance time. The protective cover features a double-sided water inlet and a double-row staggered spray structure, making the drum body easier to clean and providing a more thorough dilution and cleaning effect. The slurry tank is equipped with a guide wall. Under the action of the stirring device, the material circulates along the guide wall, achieving secondary kneading and loosening of the slurry, further separating impurities and reducing fiber loss!

[0003] However, besides the aforementioned technical advantages, the rotary drum screen also has some drawbacks. The rotary drum screen assembly consists of a high-strength roller belt, an intermediate drum, and a discharge port. After the material reacts and separates in the intermediate drum, most of the liquid is discharged through the screen holes and enters the collection tank. The remaining liquid is discharged with the material from the discharge port and enters subsequent processes. This requires further treatment of the liquid within the material to avoid affecting the quality of the finished product. This not only increases the number of processing steps and equipment, raising costs, but also results in some liquid loss and resource waste. Furthermore, some of the liquid evaporates into the air when discharged from the outlet, causing environmental pollution, affecting the health of production personnel, and making it difficult to meet environmental impact assessment standards. Utility Model Content

[0004] The purpose of this invention is to provide a rotary drum screen that solves the aforementioned problems existing in the current use of rotary drum screens.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotary drum screen includes a first high-strength roller belt, a second high-strength roller belt, a reaction zone cylinder, and a washing and drying zone cylinder. The first high-strength roller belt is connected to one end of the reaction zone cylinder, and the second high-strength roller belt is connected to the other end of the reaction zone cylinder. The washing and drying zone cylinder includes a washing zone cylinder, a drying zone cylinder, and an outlet zone cylinder. The washing zone cylinder is connected to the second high-strength roller belt. The washing zone cylinder, the drying zone cylinder, and the outlet zone cylinder are arranged sequentially. The washing zone cylinder is used to wash the material, the drying zone cylinder is used to separate the moisture from the material, and the outlet zone cylinder is used to discharge the dried material.

[0007] Furthermore, the first high-strength rolling belt includes a first rolling belt, a first rolling belt cylinder assembly, a large toothed ring, and an inlet baffle plate. The first rolling belt cylinder assembly is connected to the end of the reaction zone cylinder. The first rolling belt is sleeved on the first rolling belt cylinder assembly. The large toothed ring is sleeved on the first rolling belt cylinder assembly and located on one side of the first rolling belt. The inlet baffle plate is disposed at the end of the reaction zone cylinder.

[0008] Furthermore, the second high-strength roller belt includes a second roller belt, a second roller belt cylinder assembly, and a discharge hopper. The second roller belt cylinder assembly is disposed between the reaction zone cylinder and the washing and drying zone cylinder. The second roller belt is sleeved on the second roller belt cylinder assembly, and the discharge hopper is disposed inside the second roller belt cylinder assembly.

[0009] Furthermore, the reaction zone cylinder includes a left end cylinder, a middle cylinder, a right end cylinder, a first partition plate, a first lifting plate, and a first inclined support plate. The left end cylinder is connected to the first roller cylinder device, and the right end cylinder is connected to the second roller cylinder device. The first partition plate, the first lifting plate, and the first inclined support plate are all arranged along the axial direction of the left end cylinder, the middle cylinder, and the right end cylinder.

[0010] Furthermore, the washing zone cylinder is provided with a second partition plate, a second lifting plate and an outlet partition plate. The second partition plate and the second lifting plate are disposed in the washing zone cylinder and the spin-drying zone cylinder, and the outlet partition plate is disposed at the end of the outlet zone cylinder.

[0011] The beneficial effects of this utility model are:

[0012] This utility model relates to a rotary drum screen. A first high-strength roller is connected to one end of the reaction zone cylinder, and a second high-strength roller is connected to the other end. The washing and drying zone cylinder includes a washing zone cylinder, a drying zone cylinder, and an outlet zone cylinder. The washing zone cylinder is connected to the second high-strength roller. These three cylinders are arranged sequentially. In actual operation, the material enters through the first high-strength roller end and reacts fully with the sprayed pesticide solution within the reaction zone cylinder. The material is then dispersed, and a portion of the pesticide solution separates from the material and exits through the screen holes on the reaction zone cylinder, entering a collection tank. A portion of the residual liquid continues to move forward with the material, entering the washing zone cylinder from the second high-strength roller. The material is then further separated and diluted, and the residual liquid is removed from the material, allowing it to drain into the collection tank. The washed material then enters the drying zone cylinder, where it is lifted and slides down, colliding and slamming against the cylinder to further separate the water, which then enters the collection tank. After drying, the clean material is discharged from the discharge zone cylinder. This process ensures thorough collection of the liquid, high resource recovery rate, and prevents the liquid from flowing out of the cylinder, thus improving the environment and ensuring the health and safety of employees.
