Abstract
A bin type pump comprises a bin and a transition joint and is characterized in that the bin and the transition joint are connected by a flange; a power loading valve is arranged above the transition joint; a ripple compensator is arranged above the powder loading valve; a cutoff valve is arranged above the ripple compensator. The powder loading valve and the cutoff valve are both starting ball valves. The cutoff valve, the ripple compensator and the powder loading valve are connected by flanges. According to the bin type pump, the maintenance time is shortened, a worker does not need to enter a pump body to maintain and the operation safety performance is improved.
Description
Technical field
The utility model belongs to the defeated powder cone pump of a kind of system.
Background technology
The coal dust manufacturing shop of NeiMenggu BaoGang GangLian Co., Ltd's iron-smelter is blast furnace process supply coal dust.Along with blast furnace productive output increases, the demand of coal dust is also increased day by day, the repair time requirement of producing defeated powder equipment for coal dust manufacturing shop is more and more tighter, then there is no the picture possibility of long-time stop production to overhaul in the past, and therefore original equipment can not meet current needs.
The defeated powder cone pump of system originally, the charge mode of design is that feed valve and clock valve are used in conjunction with, and cone pump use procedure is: open fall apart-open-feed valve of clock valve turn round-fill powder-after-stop the defeated powder of diffuse-punching press of feed valve-Guan Zhongfa-pass.In closing clock valve process, because feed valve is blade diaphragm valve, not sealing, the coal dust in fine powder storehouse has on a small quantity to be let out and is fallen on clock body by feed valve, and material folding when clock valve cuts out, after frequent use, clock valve cushion rubber damages, while causing the defeated powder of cone pump, pump pressure is leaked, cannot normal defeated powder, must maintenance change O-ring seal.During maintenance, need to enter in cone pump container, sometimes also need to get angry, very easily cause blast, have very large potential safety hazard, and the upkeep operation time be long.
Aborning because feed valve does not belong to seal valve class, after feed valve shuts down, there is a small amount of coal dust to continue to fall by feed valve, when closing clock valve, between clock face and seal ring, always there is coal dust, very easily damage seal ring, cause cone pump pressure release in to the defeated powder process of blast furnace, cause blast furnace pulverized coal feed pipe to stop up, affect blast furnace and normally jet, the normal demand of producing of out of reach; When seal ring is changed in maintenance, need to enter operation in cone pump simultaneously, in pump, have certain density coal dust dust and communicate with atmosphere, run into spark or static and discharge, very easily produce blast, have very large potential safety hazard, and the upkeep operation time is long, can not adapts to current need of production.
Summary of the invention:
The purpose of this utility model is to provide a kind of shortening repair time, does not need workman to enter pump body maintenance, improves a kind of cone pump of job safety performance.
The purpose of this utility model is realized by following mode:
A cone pump, comprises feed bin, it is characterized in that: above feed bin, be transition segment, feed bin is connected by flange with transition segment, and transition segment top is dress powder valve, and dress powder valve top is FlexbleJoint, and FlexbleJoint top is shutoff valve.
Dress powder valve and shutoff valve are startup ball valve.
Shutoff valve, FlexbleJoint, dress powder valve connect by flange mutually.
Beneficial effect:
Cone pump feed valve replaces with the ball valve of connecting with clock valve, and upper ball valve is shutoff valve, and lower ball valve is dress powder valve.Cone pump use procedure is: open loose-dress powder open-cut off open-fill powder-after-close shutoff valve-pass to fill the defeated powder of diffuse-punching press of powder-pass.
The effect of FlexbleJoint is the displacement that equipment is in operation.
Before and after cone pump transformation, comparison is as follows:
Accompanying drawing explanation:
Fig. 1 is original cone pump structural representation;
Fig. 2 is the utility model structural representation;
Wherein: 1-shutoff valve, 2-FlexbleJoint, 3-dress powder valve, 4-transition segment, 5-delivery pipe, 6-feed bin, 7-feed valve, 8-clock valve.
The specific embodiment:
A cone pump, comprises feed bin 6, it is characterized in that: the top of feed bin 6 is transition segment 4, and feed bin 6 is connected by flange with transition segment 4, and transition segment 4 tops are dress powder valve 3, and dress powder valve 3 tops are FlexbleJoint 2, and FlexbleJoint 2 tops are shutoff valve 1.
Dress powder valve 3 and shutoff valve 1 are pneumatic ball valve.
Shutoff valve 1, FlexbleJoint 2, dress powder valve 3 all connect by flange.
Transition segment 4 is frustum type, and frustum large mouth and feed bin join, and frustum is connected with dress powder valve 3 compared with osculum.
Improved cone pump, has solved the problem of the defeated powder pressure release of cone pump, has guaranteed that blast furnace normally jets, and has shortened the upkeep operation time, has improved upkeep operation personnel's safety control.
