Abstract
The utility model discloses a lime powder feeding device and aims to provide the lime powder feeding device capable of rapidly discharging lime powder transported by a cement tank car into a high lime powder storage. The lime powder feeding device comprises a discharge joint, a horizontal conveying pipe, a vertical conveying pipe and a boosting compressed air tube connected with compressed air, wherein the boosting compressed air tube is connected with the vertical conveying pipe by at least one connecting hose. The lime powder feeding device has simple structure and is convenient to use; by inputting boosting air into the conveying pipes, the lime powder in the cement tank car can be rapidly discharged into the high lime powder storage; and in the discharging process, the dust flying cannot be caused.
Description
Technical field
The utility model relates to a kind of feeding device, especially a kind of pulverized limestone feeding device.
Background technology
The pulverized limestone feeding device is used in existing desulfurization, adopts bulk cement carrier directly to squeeze into the pulverized limestone storehouse or deliver into the pulverized limestone storehouse with mechanical transport mode such as bucket elevator with carrying air plant usually.
Mechanical transport mode such as bucket elevator carrying method need be discharged to bulk powder in the little storehouse and expect in the mechanical transmission device down, exist discharge rate slow, and dust such as flies away at shortcoming during discharging.
Because there is above shortcoming in the mechanical transport mode, so adopt bulk cement carrier directly with carrying the method that air plant is squeezed into the pulverized limestone storehouse usually, having following defective bulk cement carrier operation pressure is 0.2MPa;, operation pressure stops air feed after reaching 0.2MPa; Treat just to begin air feed again after pressure decay to a certain degree, such mode of operation has determined that best conveying vertical dimension is 15 meters, 5 meters of horizontal throws; Surpass this scope, discharge rate obviously reduces or can't carry at all.And above-mentioned transportation parameters is only to cement, if carry the bigger suitable conveying vertical dimension of agstone of bulk density lower.Desulfurization is at present arranged a large amount of equipment with the pulverized limestone storehouse below the storehouse; And the long-pending requirement of storage capacity is bigger; The storehouse heights of roofs is higher, usually greater than 20 meters, adopts bulk cement carrier directly to squeeze into the method discharge rate in pulverized limestone storehouse and can't carry very slowly or at all with carrying air plant.
Summary of the invention
The purpose of the utility model is to overcome deficiency of the prior art, and a kind of pulverized limestone feeding device that can the pulverized limestone that bulk cement carrier transports be quickly discharged into higher pulverized limestone storehouse is provided.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: a kind of pulverized limestone feeding device; Comprise discharging joint, horizontal conveying pipe, vertical transport pipe; Also comprise connecting compressed-air actuated boosting compressed air tube, said boosting compressed air tube links to each other through at least one hose with the vertical transport pipe.
Further, said hose links to each other with the vertical transport pipe through check valve, prevents boosting air-flow generation adverse current.
Further, said hose links to each other with the boosting compressed air tube through flow control valve, can control the compressed-air actuated influx of boosting.
Further, said hose has at least two, and the spacing of said adjacent hose is 3～7 meters, and guaranteeing has enough air pressure to transport pulverized limestone in the pipe.
Further, the caliber of said boosting compressed air tube is DN40～DN65, can guarantee that air pressure meets the requirements in the boosting compressed air tube.
Further, along the pressurized air flow direction valve, compression indicator are housed successively on the boosting compressed air tube in said hose the place ahead, make things convenient for the user to control the air pressure in the boosting compressed air tube.
The beneficial effect of the utility model is: simple in structure, easy to use, and through with the pulverized limestone in the bulk cement carrier being quickly discharged into higher pulverized limestone storehouse in the boosting air input delivery pipe, and can not cause dust to fly away during discharging.
Description of drawings
Fig. 1 is a kind of pulverized limestone feeding device of the utility model structural representation;
Fig. 2 is the right elevation of a kind of pulverized limestone feeding device of the utility model;
Fig. 3 is an I enlarged drawing among Fig. 2.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described:
In Fig. 1 Fig. 2; A kind of pulverized limestone feeding device; Comprise discharging joint 2, horizontal conveying pipe 3, vertical transport pipe 4, also comprise connecting compressed-air actuated boosting compressed air tube 6 that said boosting compressed air tube 6 links to each other through at least one hose 10 with vertical transport pipe 4.
In Fig. 3, said hose 10 links to each other with vertical transport pipe 4 through check valve 11, prevents boosting air-flow generation adverse current.Said hose 10 links to each other with boosting compressed air tube 6 through flow control valve 9, can control the compressed-air actuated influx of boosting.Said hose 10 has five, and the spacing of said adjacent hose 10 is 5 meters, and guaranteeing has enough air pressure to transport pulverized limestone in the pipe.The caliber of said boosting compressed air tube 6 is DN40～DN65, can guarantee that air pressure meets the requirements in the boosting compressed air tube 6.Along the pressurized air flow direction valve 8, compression indicator 7 are housed successively on the boosting compressed air tube 6 in said hose 10 the place aheads, make things convenient for the user to control the air pressure in the boosting compressed air tube.
During discharging; After discharging joint on the horizontal conveying pipe 42 and discharge port on the bulk cement carrier 1 joined; The air plant that startup bulk cement carrier 1 carries is with in the input of the pulverized limestone in the bulk cement carrier 1 pulverized limestone storehouse 5; Simultaneously Open valve 8 is observed the pressure display on the compression indicator 7, and it is about 0.25Mpa that 8 the aperture of regulating the valves makes the pressure display value.After the pulverized limestone discharging finishes, stop the air plant that bulk cement carrier 1 carries, valve-off 8 is taken discharging joint 2 apart.
