Description
Technical Field
[0001] This utility model relates to the field of dust removal technology for dryers, specifically a dust removal device for dryers. Background Technology
[0002] Dryers come in several modes, including belt dryers, drum dryers, box dryers, and tower dryers; heat sources include coal, electricity, and gas; materials are dried using hot air flow and radiation methods. In hot air drum dryers, hot air flows from the tail to the front, making full contact with the material and fully utilizing heat transfer through heat conduction, convection, and radiation. During the use of the dryer, a dust removal device is required to remove dust from the raw materials to be dried.
[0003] According to the patent application CN 222069219U, "This utility model discloses a dust removal device for a grain dryer, including a placement platform, a geared motor, and a blower. The geared motor and the blower are sequentially arranged on the placement platform, and the geared motor drives the blower. An adjustment plate is provided outside the blower, and the opening or closing of the adjustment plate controls the airflow. A long pipe is connected to the blower, and the long pipe is connected to a double channel. The double channel is connected to an air outlet pipe, and the air outlet pipe faces the elevator. This utility model has a novel and reasonable structural design, which can reduce dust and light impurities in grains, making production safe and efficient."
[0004] Regarding the above description, the applicant believes the following issues exist:
[0005] In operation, the grains are transported upwards by an elevator and then poured downwards through a hopper. The poured grains slide down a guide plate. During this process, airflow from a blower enters the elevator through a dual-channel system and blows onto the falling grains, removing light dust from their surface. However, in actual use, the blower's air inlet is constantly open, which can easily cause blockages or blow dust from the outside air into the raw materials. Furthermore, after the device blows air to remove dust from the raw materials, the dust also disperses into the outside air, affecting the operating environment. Therefore, it is necessary to improve the dust removal device for the dryer to solve the above problems. Utility Model Content
