Description

Technical Field

[0001] The utility model relates to the technical field of filter bag devices, in particular to a filter bag device suitable for the coal slime drying industry. Background Art

[0002] Coal slime, due to its high moisture content, high viscosity, high water holding capacity, and low calorific value, presents numerous disadvantages, making it difficult to commercialize. This has long been a barrier to entry for power users, with its primary outlet being residential sales. Since the reform and opening-up policy, the national economy has experienced rapid growth, with coal production now ranking first in the world and the market undergoing significant changes. The breadth and depth of coal processing have rapidly expanded, significantly increasing coal slime production. The comprehensive utilization of coal slime has become a pressing issue. Consequently, with the continuous advancement of economic science in my country, coal slime drying technology has become increasingly popular among manufacturers, leading to the development of coal slime dryers.

[0003] In the process of realizing the present invention, the inventors discovered that the prior art has the following problems: since the coal slime has a high viscosity, the filter bags used during drying may be stuck together by the sticky dust, thereby reducing the filtering effect.

[0009] Beneficial effects

[0010] The utility model provides a filter bag device suitable for the coal slime drying industry. The utility model is designed with a structure that can increase the coal slime filtration area. First, the filter bag body is movably mounted on the first annular plate and the first support rod, and the filter bag body is movably inserted into the second annular plate. A pair of insert plates and a pair of insertion holes are aligned. At this time, a plurality of first support rods and a plurality of second support rods are staggered to form the filter bag body into a wavy shape. The screw knob is screwed to drive the pair of insert plates to be inserted into the pair of insertion holes respectively, thereby fixing the filter bag body. The device supports the filter bag into a wavy shape through the staggering between the support rods, increases the dust removal area, can effectively avoid the problem of reduced filtration effect caused by the adhesion of coal slime dust, and can achieve rapid installation and removal by screwing, making the filter bag more stable.
