Description
Technical field
The utility model relates to a kind of throwing device, particularly a kind of high precision lime throwing device.
Background technology
In water treatment and desulfurization and dedusting industry, calcium hydroxide is widely used in the technologies such as acid-base neutralisation, lime precipitation.Calcium hydroxide usually is applied in the municipal sewage treatment as the acid-base neutralisation agent of cheapness especially; Can be used as the make up water of thermal power plant's recirculated cooling water through the city reuse water after the lime advanced treatment, the electric power plant circulating water make up water adopts the city reuse water to become the approach of municipal sewage as a resource.
Lime throwing device usually is used in the WWT; Mostly existing traditional lime throwing device is bottom reciprocating sieve, rotary valve and the such equipment of common simple helix feeding machine; Adopt the Measuring Precision of this kind equipment usually not reach 5%, and easy blocking, make operator's work under bad environment, labour intensity is big and effluent quality can't guarantee; Simultaneously because coarse metering produces very big waste.
ZL200620124561.3 discloses a kind of many spirals high precision lime throwing device; Comprise: be provided with in the feeding machine and add mechanism; It is characterized in that: the described mechanism that adds is by being at least 2 feed auger; Feed auger drives through power-driven gear, and makes adjacent feed auger speed identical, and rotation direction is opposite and spiral is overlapping; Be provided with inlet flange above the described feeding machine and the bottom is provided with discharge flange, discharge flange is located at the below of feeding machine of end of feed auger or right-hand.It is through one group of rotation that interact to produce the spiral of overlap, produce safety, continuously, stable, add metering and low wearing and tearing, self-cleaning spiral accurately; Can guarantee simultaneously the continuity of charging.
Though above-mentioned many spirals high precision lime throwing device has improved the particularity that adds metering to a certain extent, has guaranteed the continuity of charging, effect is not very desirable.And in lime throwing device, as the lime silo of one of key equipment, whether the design of its key position bottom is to tying arch, forming phenomenon important influence such as cavity, fracture in the silo.At present; Common lime silo bottom adopts the angle of hopper barrel and horizontal direction to be not more than 45 ° feed bin; Though the lime silo of design provides maximum storage capability like this, do not consider that actual unloading performance is little owing to stored immobilising powder; Can not accomplish continuously feeding, tie arch in the silo easily, form phenomenons such as cavity, fracture.And, fail to control the hole bridge formation of lime from material itself, very easily cause lime in feed bin, to form the hole; Be unfavorable for the lime blanking, cause obstruction, cause the lime Flow of Goods and Materials inhomogeneous through regular meeting; Even cutout, except that having increased greatly the maintenance workload, also reduced the rate of utilization of silo and equipment; The particularity of metering be can't guarantee to add, thereby wastewater treatment and desulfurization and dedusting effect influenced.
The utility model content
For solving the problems of the technologies described above; The utility model provides a kind of high precision lime throwing device; Solved fundamentally that the lime adding equipment often stops up, blanking is inhomogeneous, the time little when big, be prone to produce the problem in hole, improved lime feed tolerance range and continuity, thereby guaranteed the effluent quality of total system; Reduced running cost, production security is greatly improved.
