Technical field
The present invention relates to homogenizing filter plant technical field more particularly to a kind of chemical gypsum homogenizing filter plant and
Change filter method.
Background technology
Chemical gypsum refers to being referred to as chemistry in industrial by-products or emission with calcium sulfate object as main component
Gypsum.It is all trade waste mainly to have desulfurated plaster, ardealite, titanium gypsum, nickel gypsum, fluorgypsum etc..It is more per annual emissions
Up to more than one hundred million tons, such as develop and use not in time, serious pollution can be generated to soil, water source, air, destroy the mankind ecological environment and
Life condition.Therefore, the meaning of utilization chemical gypsum resource, which is not only in that, can replace the natural gypsum, and alleviate solid
The exhaust emission of body waste residue reduces the landfill expense of solid slag costliness.Homogenizing filtering can be done much with the gypsum calcined out
The materials for wall of kind, such as Thistle board, self-insulation gypsum building block, gypsum wallboard etc..It is that solid waste comprehensively utilizes
Model meets national energy conservation and emission reduction, is recycled the policy of economy and sustainable development.
Since the initial ejection object of chemical gypsum is that moisture content is higher and the emery dust shape or muddy of easy fluctuation, directly
Drying causes equipment to stop up, corrode and a large amount of energy consumption waste, therefore has to carry out the place of next step by homogenizing filtering
Reason.It is infeasible by drying canopy natural removal absorption water to be presently used for chemical gypsum, common filter plant, such as very
Empty belt filter, plate and frame filter press etc. only have the effect of effect of the filtering without homogenizing, and large-scale application equipment
Investment is big, and the equipment of selection covers very much more, and economic benefit is low, and the gypsum product quality filtered out is very unstable, and quality is difficult to improve, directly
Connecing influences the quality of downstream product；Meanwhile the filter method of existing filtration system needs manual operation mostly, it is time-consuming and laborious,
Inefficiency is not suitable for extensive filtration treatment.
Invention content
In order to solve existing chemical gypsum homogenizing filtering, a kind of chemical gypsum of present invention offer is with
Change filter plant and homogenizing filter method, device and method of the invention can realize the extensive homogenizing filtering of chemical gypsum,
The absorption water of chemical gypsum by tentatively filtering, after secondary filter, homogenizing reduces 50-60%, and filtering is uniform, filter effect
Good, filter efficiency is high, and the gypsum product stable quality filtered out, quality is improved, while ensure that the quality of downstream product.
The present invention is achieved through the following technical solutions, and one aspect of the present invention provides a kind of chemical gypsum homogenizing filtering

6. a kind of chemical gypsum according to claim 1 homogenizing filter plant, it is characterised in that：In the material grasping bucket
Vibrating head is installed at the gripper of arbitrary one or both sides.
7. a kind of homogenizing filter method for using homogenizing filter plant according to claim 1~6 any one of them chemical gypsum,
It is characterized in that：Include the following steps：
1) it feeds：Gypsum is from the laydown area that access way is uniformly added into kiln road；
2) it filters：Gypsum passes sequentially through orifice plate filter layer, filter-cloth filtering layer in the water filtering tank of the bottoms Yao Dao and is filtered, and filters out
Moisture flows into collecting-tank by collecting box and collects；
3) homogenizing discharging：Filtered gypsum is captured according to setting program sequence multiple spot in kiln road by the material grasping bucket at the top of kiln road
Material, the storage bin hopper into production line discharge, and realize the homogenizing of material；Discharging is completed to continue to add moisture content height into this kiln road
Gypsum be filtered and be homogenized discharging the step of, several kiln roads are used alternatingly.
8. a kind of homogenizing filter method of chemical gypsum homogenizing filter plant according to claim 7, it is characterised in that：
In step 3), the vibrating head installed on material grasping bucket can vibrate the material near material grasping bucket, accelerate the rate of water loss of material nearby.
9. a kind of homogenizing filter method of chemical gypsum homogenizing filter plant according to claim 7, it is characterised in that：
In step 3), material grasping bucket realizes that transverse and longitudinal moves under the drive of movable type traveling crane, is realized up and down under the drive of lifting motor
Movement, movable type traveling crane, lifting motor, material grasping bucket automatically control feeding point by production technology.
10. a kind of homogenizing filter method of chemical gypsum homogenizing filter plant according to claim 7, feature exist
In：In step 2), the vacuum pump set in collecting box generates negative pressure for accelerating science of law gypsum dehydration.
