Description

Technical Field

[0001] The utility model belongs to the technical field of sewage decontamination equipment, and more specifically relates to a high-efficiency sealing structure of a rotary grille decontamination machine and a grille decontamination machine with the sealing structure. Background Art

[0002] Rotary screen decontamination machines are widely used in sewage treatment, industrial wastewater treatment and other fields to separate solid particles from liquids. However, traditional rotary screen machines have some problems in sealing, such as poor sealing effect and easy leakage, which not only affects the normal operation of the equipment, but also increases maintenance costs and may even cause secondary pollution to the environment. Therefore, how to design an efficient and reliable sealing structure to improve the operating efficiency and stability of the rotary screen machine has become an urgent problem to be solved in this field.

[0003] After searching, the Chinese patent authorization announcement number is CN204973267U, the announcement date is January 20, 2016, and the name of the invention is: inner diameter flow grid sewage remover. The inner diameter flow grid sewage remover disclosed in the patent document includes a sewage remover body, a sprocket, a guide rail and a filter plate. The guide rail is installed on the side wall of the sewage remover body, and sprockets are installed on both sides of the bottom of the filter plate. The filter plate slides with the guide rail through the sprocket. It also includes a seal. The seal is installed on the guide rail and the width is the same as the distance from the side wall of the sewage remover body to the edge of the filter plate. In the patent document, a seal is set. Through the set seal, the guide rail and the side wall of the sewage remover body can be in a sealed state to a certain extent. Such a structure ensures that when the filter plate filters sewage, the sewage will not flow into the filtered clean water due to the gap between the filter plate and the sewage remover body. However, the seal provided in the patent document is made of synthetic rubber, which has a short service life, is prone to aging, and is easily damaged after long-term wear, thereby affecting the sealing effect. It often needs to be replaced, the equipment is frequently shut down for maintenance, and the cost of decontamination is high. Utility Model Content
