Abstract
The utility model belongs to the fly ash conveying field of a large coal-fired generator set, specifically which is a pneumatic jetting and conveying pump for thick-phase powder particles. The utility model comprises a pump body, wherein, a feeding valve, an exhaust valve and a discharging gate are arranged on the pump body; the discharging gate is connected with a conveying pipe on which a jetting valve is arranged, wherein, a valve on the discharging gate has a spherical structure, and the valve is sealed by an air-cushion movable sleeve and a sealing ring; thus the discharging gate is sealed completely; the utility model is at least provided with two air complementing holes, and thus the efficiency of fluidization is high; at least two pump bodies are mutually connected in parallel via the conveying pipe, and thus conveyance can be continuous. The utility model has the advantages of low energy consumption, small abrasion and low comprehensive and running cost.
Description
The utility model relates to large-scale coal fired power generation unit ash transfer field, specifically is powder concentrated phase air injection transfer pump.
Powder, granule strength are carried and are started late in China.But along with the attention of country to environmental protection, each research unit and producer have all strengthened dynamics to its research, and the also just progressively sealed shape strength of the conveying of powder is carried and replaced.It is that operation troubles is many that strength conveying now is difficult to received reason, plugging is serious, energy consumption height, operating cost are considerably beyond miscellaneous equipment, and the user who has selects import equipment for use, its cost is very expensive, be more than ten times even tens times of home equipment, and China is vast in territory, the height above sea level discrepancy in elevation is big, temperature, humidity have nothing in common with each other, and import equipment is difficult to be suitable for.Home equipment operation rotating component is many, and sealing difficulty is big.Its basic running is: charging exhaust → material is completely closed charging exhaust → open carburation by spraying → sent and is blown the circulation next time that remains static → enter of surplus to the greatest extent ash → close carburation by spraying flow velocity.This operation energy waste is serious, the operating pressure height, and wearing and tearing are big, and injection valve very easily damages.
The purpose of this utility model provides a kind of powder concentrated phase air injection transfer pump at the problems referred to above exactly, and it is low to have energy consumption, and it is little to wear and tear, the characteristics that the operation comprehensive cost reduces greatly.
The technical solution of the utility model is: comprise the pump housing, feeding valve, outlet valve and discharge door are housed on the pump housing, are connected with delivery pipe, injection valve is housed on the delivery pipe with discharge door, it is characterized in that the valve on the discharge door is a spherical structure, and by air cushion type movable sheath and seal ring sealing.
According to technique scheme, because the valve of spherical structure is housed on the discharge door of the present utility model, and seal by air cushion type movable sheath and seal ring, when foreign matter, can realize compensation automatically, good airproof performance, and improved greatly its working life.When opening, avoid flow-passing surface fully, do not had any wearing and tearing during conveying.Simultaneously, because the hermetically sealed property of discharge door makes conveyance conduit and the pump housing isolate entirely, the phase mutual interference when having avoided conveying, thus can realize the continuous conveying of a plurality of pump housings.
The utility model is provided with tonifying Qi hole, two places at least, lays respectively at the bottom and the discharge door place of the pump housing.Tonifying Qi hole in the pump housing produces fluidisation for the first time, and by gas flow in the control pump housing, can directly control quantity delivered, and the tonifying Qi hole at discharge door place produces fluidisation for the second time, makes powder can send into conveyance conduit equably.Because of it makes powder be subjected to the effect of air cushion around discharge door, simultaneously material is carried out tonifying Qi, discharge door is not had direct wearing and tearing, and make the discharge door Sealing avoid the powder wearing and tearing fully.The material that enters in the delivery pipe carries out fluidisation for the third time under the effect of conveying gas.Promptly at the conveying initial segment of powder, what show owing to its air content is limited is the higher powder group of density, produces strong eddy current when the high velocity jet air-flow enters convergent-divergent channel, gas, powder are fully mixed, make air potential energy be converted into kinetic energy at the trunnion position, produce malleation and carry out the pressure reduction conveying, therefore, the utility model fluidization efficiency height, make powder good fluidity before conveying, increased the easy property of stream of pellet, reduced wearing and tearing feedway, prolong working life, reduced maintenance workload greatly.
The utility model has at least two pump housings parallel with one another by delivery pipe, like this, opens injection valve, two interior material of the pump housing just can take turns continuously to carry, and making does not have back pressure in the course of conveying, and no pigging blows sky, reduced the consumption of the energy, reduced discharge pressure, reduced and carried wearing and tearing.
Therefore, the powder concentrated phase air injection transfer pump novel structure that the utility model provides, reasonable in design, have wearing and tearing little, the life-span is long, less energy consumption, cost is low, the characteristics that performance is good have tangible economic benefit and social benefit.
Describe in detail below in conjunction with embodiment's accompanying drawing.
At first accompanying drawing is described:
Fig. 1 represents structural representation of the present utility model;
Fig. 2 represents the structural representation of discharging valve;
Fig. 3 represents the embodiment of two pump housing parallel connections.
Referring to accompanying drawing, comprise two pump housings 9, feeding gate 1, level-sensing device 2, outlet valve 3, discharge door 6 and pressure gauge 8 are housed on each pump housing 9, the below of discharge door 6 be conveyance conduit 12 as shown in Figure 1, and two pump housings 9 are connected in parallel, as shown in Figure 3, injection valve 7 is housed on the conveyance conduit 12, bottom, discharge door 6 places at the pump housing 9 are provided with tonifying Qi hole 5 respectively, the valve 61 of discharge door 6 be spherical structure as shown in Figure 2, and is connected with moving runner 63 by connecting rod 62, ball valve 61 passes through air cushion type movable sheath 64 seal rings 65 and seals.11 is door to access among the figure; 10 is support foot, and 4 is carbureting valve.Its working principle and process are, at first open injection valve 7, open A, the feeding gate 1 of two pump housings 9 of B, exhaust valve 3 carries out charging, level-sensing device 2 shows that material is full, close the exhaust valve 3 of the A pump housing 9, feeding gate 1, and open the discharge door 6 of the A pump housing 9, promptly rotate moving runner 63, drive ball valve 61 by connecting rod 62 discharge door 6 is opened, open the gasification valve 4 of the A pump housing 9, promptly carrying out air injection carries, discharging finishes, and closes the discharge door 6 of the A pump housing 9, closes the gasification valve 4 of the A pump housing 9, open the discharge door 6 of the B pump housing 9, open the gasification valve 4 of the B pump housing 9, carry out air injection and carry, simultaneously, open the feeding gate 1 of the A pump housing 9, carry out the conveying of the A pump housing 9 after the material of the B pump housing 9 is carried and finished again.Make and carry uninterruptedly, injection valve 7 per tour time rotation once.
