Embodiment Construction

[0016] Such as figure 1 , 2 As shown, a distributing device of a disc filter is located at the feeding part of the tank body 1 of the disc filter, including: a distributing trough 5, a collecting box 4, a flange feeding port 3, and a fan-shaped plate 2. The flange feed inlet 3 on the tank body 1 communicates with several collection boxes 4 on the tank body 1, and the collection boxes 4 and the corresponding parts on the surface of the fan-shaped plate 2 are evenly distributed with distribution grooves 5.

[0017] A distributing method for a disc filter, the steps are as follows:

[0018] 1. Install a collection box 4 with the function of distributing material on the feeding part of the slurry tank body 1 of the disc filter;

[0019] 2. The feed slurry first enters the collection box 4 through the flange feed port 3, and when the slurry fills the collection box 4, the liquid slurry flows out through a number of evenly distributed distribution grooves 5 in the collection box 4...

Abstract

The invention belongs to the technical field of a disc vacuum filter and discloses a burden distribution device of a disc filter and a method thereof. The device by the method is positioned at a feeding position of a tank 1 of a disc filter, and comprises a burden distribution tank 5, material collecting boxes 4, a flange feed inlet 3 and a sector plate 2. The flange feed inlet 3 on the tank 1 is communicated with several material collecting boxes 4 on the tank 1. A corresponding position of the material collecting box relative to the board of the sector plate 2 is uniformly provided with a distributing trough 5. The burden distribution device can still operate normally when feed quantity of the disc filter is reduced or unstable and then the liquid level in the filter tank is low. By uniformly spraying slurry onto the surface of the sector plate, vacuum leak is avoided, and normal operation of the filter is guaranteed. The burden distribution device of the disc filter has a simple and reliable structure and is easy to promote.

Description

technical field [0001] The invention belongs to the technical field of disc vacuum filters, and in particular relates to a material distribution device and method for disc filters. Background technique [0002] Disc filters are widely used in various industries such as aluminum hydroxide seed filtration, flotation concentrates in the coal industry, and solid-liquid separation of fine-grained particles such as tailings. Now it is expanding its application to the field of gypsum slurry dehydration in power plants. [0003] When the traditional disc filter is in normal operation, the slurry in the tank requires overflow operation, also known as full tank operation, to ensure that the slurry immerses the entire fan-shaped plate, thereby ensuring the vacuum degree in the fan-shaped plate. When the disc filter is used as the secondary dehydration equipment for the dehydration of gypsum slurry in the power plant, due to the process of the system, its material supply is very unstabl...
