Description

Technical Field

[0001] The invention belongs to the technical field of dryers and relates to a novel scraper mechanism, in particular to a novel scraper mechanism for a dryer. Background Art

[0002] There are several modes of dryers, such as belt drying, drum drying, box drying, tower drying, etc. The heat sources include coal, electricity, gas, etc. The materials are dried in hot air flow and radiation processes. Hot air drum drying is a process in which the hot air flow moves from the tail to the front, fully contacts the materials, and fully utilizes the heat transfer through heat conduction, convection, and radiation. The heat energy is directly transferred to the materials, so that the moisture of the materials is continuously evaporated in the drum. The induced draft device at the inlet draws out a large amount of moisture and wet air flow to prevent secondary pollution caused by dust discharge. The material movement is promoted through internal spiral stirring, sweeping, and copying to complete the entire drying process. Countercurrent conduction dehumidification avoids reducing repeated drying procedures.

[0003] In the prior art, during the production process of the dryer, the material adheres to the inner wall of the drying drum, thereby reducing the drying effect of the material. After the material is dried, when it needs to be discharged, part of the material adheres to the inner wall of the drying drum and cannot be discharged, which affects the material yield. In addition, in order to solve the problem of the material adhering to the inner wall of the dryer, manual cleaning is generally adopted, but manual cleaning has the problems of low efficiency and high labor intensity for workers; the material with high viscosity adheres to the inner wall of the drying drum, and it is difficult to effectively clean it only by a scraper. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that during the production process of the dryer, the material adheres to the inner wall of the drying cylinder, thereby reducing the drying effect of the material. After the material is dried, when it needs to be discharged, part of the material adheres to the inner wall of the drying cylinder and cannot be discharged, which affects the material yield. In addition, in order to solve the problem that the material adheres to the inner wall of the dryer, manual cleaning is generally adopted, but manual cleaning has the characteristics of low efficiency and high labor intensity for workers; the material with high viscosity adheres to the inner wall of the drying cylinder, and it is difficult to effectively clean it only by a scraper. Therefore, a new scraper mechanism for a dryer is proposed.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A novel scraper mechanism for a dryer comprises a drying cylinder and a scraper;

One end of the connecting pipe extending into the working cylinder extends into the connecting plate. The connecting pipe is fixedly connected to the connecting plate, and one end of the connecting pipe extending into the working cylinder is connected to the middle part of the diverter pipe. Water outlets are respectively provided at both ends of the diverter pipe. The water outlet of the diverter pipe is rotatably connected to the connecting branch pipe through a sealing bearing. The other end of the connecting branch pipe passes through the connecting plate and is rotatably connected to the connecting plate. The other end of the connecting branch pipe extends into the drying cylinder. A scraper is provided on one side of the connecting branch pipe. The scraper is a U-shaped structure, and the horizontal part of the scraper abuts against the inner wall of the drying cylinder. A plurality of groups of spray holes are evenly provided on the side wall of the connecting branch pipe away from the scraper.

[0009] Preferably, the length of the connecting plate is matched to the inner diameter of the working cylinder, the length of the connecting branch pipe is matched to the length of the drying cylinder, and the horizontal part of the scraper is matched to the length of the drying cylinder.

The second driving motor is installed on the inner wall of the connecting plate, the output end of the second driving motor is connected to the second driving pulley, and the second driven pulley is sleeved on the outer wall of the connecting branch pipe.

[0012] Preferably, the second driving pulley is located between the two groups of second driven pulleys, and the second driving pulley is connected to the second driven pulley via a second conveyor belt transmission.

When in use, the first driving motor is started to rotate, the first driving motor works, drives the first driving pulley to rotate, the first driving pulley drives the first driven pulley to rotate through the first conveyor belt, the first driven pulley drives the connecting pipe to rotate, the connecting pipe drives the connecting plate to rotate, so that the scrapers installed on both sides of the connecting plate rotate, and the scrapers clean the materials adhered to the inner wall of the drying cylinder;

[0015] S2. Connect the water inlet end of the connecting pipe to the output end of the water pump through a sealed bearing, start the second driving motor to rotate, so that the clean water enters the diversion pipe along the connecting pipe and is sprayed out from the spray hole on the connecting branch pipe. At the same time, the second driving motor drives the second active pulley to rotate, and the second active pulley drives the second driven pulley to rotate through the second conveyor belt, so that the connecting branch pipe and the scraper on the connecting branch pipe rotate, so that the inner wall of the drying cylinder is flushed through the spray hole on the connecting branch pipe, and the scraper cleans the inner wall of the drying cylinder.

By making the connecting branch pipe and the scraper rotate on their own, the efficiency of cleaning the inner wall of the drying cylinder is greatly improved, which facilitates solving the problem that high-viscosity materials adhere to the inner wall of the drying cylinder and are difficult to clean.
