Description

Structure is prevented blockking up by lime stone thick liquid delivery pump

Technical Field

The utility model belongs to the technical field of limestone slurry conveying equipment and specifically relates to a structure is prevented blockking up by limestone slurry delivery pump.

Background

The existing acidic oxidized pellet ore adopts a grate-rotary kiln-circular cooler production process, and generally adopts a limestone-gypsum wet method to carry out flue gas desulfurization treatmentAnd (6) processing. The main process system comprises: limestone slurry preparation system and SO₂An absorption system, a gypsum dehydration system, a process water system and an accident slurry discharge system. The limestone slurry preparation system adopts limestone particles to be sent into a bin, the limestone particles are sent to a ball mill by a feeder to be ground into slurry, and the limestone slurry is sent to an absorption tower by a limestone slurry pump. The limestone slurry system is designed to have a particle size at least up to 0.044mm and 90% passing 325 mesh. In actual production operation, the conditions of pipe blockage and production limit are caused due to the fact that the preparation efficiency and the particle size of the limestone do not reach the standard occasionally, production is restricted seriously, and therefore the method for improving the particle size content of fine particles in limestone slurry is adopted and is a key measure for ensuring that a pipeline is not blocked.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a limestone slurry delivery pump anti-clogging structure through improving fine particle size content in the limestone slurry is provided to effectively prevent pipe blockage.

The utility model provides a technical scheme that its technical problem adopted is: lime stone thick liquid delivery pump prevents blockking up structure, including the pond and the pump body, the pump body passes through water pump inlet channel and pond intercommunication, and the water inlet of water pump inlet channel sets up in the pond, and the water inlet of water pump inlet channel is the horn mouth type, and wherein, the opening of horn mouth is downward.

The device further comprises at least one sediment flushing pipeline, one end of the sediment flushing pipeline is communicated with a pump body water outlet pipeline of the pump body, and the other end of the sediment flushing pipeline is communicated with the inner wall surface of the bell-mouth-shaped water inlet.

Further, the sediment flushing pipeline is communicated with the top of the inner wall surface of the bell-mouth-shaped water inlet.

Further, a pipeline valve is arranged on the sediment flushing pipeline.

Further, a water tank water inlet pipeline is arranged on the side wall of the bottom of the water tank.

Further, a pool sewage discharge pipeline is arranged at the bottom of the pool.

Furthermore, the bell mouth opening of the water inlet is arranged at the position close to the bottom surface of the water pool.

The utility model has the advantages that: in practical use, because the water inlet of the water pump water inlet pipeline is designed into a bell mouth shape, and the opening of the bell mouth is downward, when limestone slurry is conveyed upwards, larger particles can obtain sufficient settling time, and most of the finer particles can smoothly flow to the water pump water inlet pipeline and flow to a downstream area along the limestone slurry upwards. The bell mouth type water inlet reduces the flow velocity of water flow flowing upwards due to the characteristic of large caliber, so that larger particles can be precipitated downwards, and the separation of large particles and small particles is realized. The utility model discloses structural design is very ingenious, and is little to the change of existing equipment, is particularly useful for among the lime stone thick liquid is carried.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Labeled as: the pump comprises a water pool 1, a pump body 2, a pump body water outlet pipeline 3, a water pool water inlet pipeline 4, a water pump water inlet pipeline 5, a sediment flushing pipeline 6, a pipeline valve 7, a water pool sewage discharge pipeline 8 and a water inlet 9.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The anti-blocking structure of the limestone slurry conveying pump shown in fig. 1 comprises a water tank 1 and a pump body 2, wherein the pump body 2 is communicated with the water tank 1 through a water pump water inlet pipeline 5, a water inlet 9 of the water pump water inlet pipeline 5 is arranged in the water tank 1, the water inlet 9 of the water pump water inlet pipeline 5 is in a bell-mouth shape, and an opening of the bell-mouth is downward.

In actual use, the water tank 1 is filled with limestone slurry, and the opening of the bell-mouth-shaped water inlet 9 is immersed below the liquid level of the limestone slurry. After the pump body 2 is started, the limestone slurry in the bell-mouth-shaped water inlet 9 gradually rises until the limestone slurry enters the water inlet pipeline 5 of the water pump and is conveyed to a required area through the pump body 2. Wherein, because the opening of horn mouth is downward, the limestone slurry rising speed is slower when rising the initial stage, and this just can let great large granule can obtain abundant time of downwarping, and the tiny particle is whole then rises to water pump inlet channel 5 along with the thick liquid in, the condition of water pump inlet channel 5 has just been prevented to such separation by the large granule, also can be smooth carry required region with the limestone slurry who mainly contains the tiny particle simultaneously. Through above-mentioned ingenious institutional advancement, the utility model discloses successful realization the separation of large granule and tiny granule to pipeline blockage has effectively been prevented.

Because after using a certain period, can appear adhering to a large amount of large granule materials on the internal face of horn mouth type water inlet 9, in order to clear up these large granule materials in time to guarantee to prevent the jam in later stage, can select such scheme: the device comprises at least one sediment flushing pipeline 6, wherein one end of the sediment flushing pipeline 6 is communicated with a pump body water outlet pipeline 3 of a pump body 2, and the other end of the sediment flushing pipeline 6 is communicated with the inner wall surface of a bell-mouth-shaped water inlet 9. As shown in fig. 1, the sediment flushing pipeline 6 flushes the inner wall surface of the bell-mouth-shaped water inlet 9 when needed, so that the bell-mouth-shaped water inlet 9 is effectively cleaned, and the anti-blocking effect is guaranteed. The number of sediment flushing lines 6 can generally be chosen according to the actual needs. In order to obtain a more thorough washing effect, it is preferable that the sediment washing pipe 6 communicates with the top of the inner wall surface of the bell-mouth type water inlet 9. In order to achieve the controllable cleaning, the sediment flushing pipe 6 is preferably provided with a pipe valve 7, as shown in fig. 1, so that the flushing can be flexibly performed according to actual needs.

In order to facilitate the input of limestone slurry, the side wall of the bottom of the water tank 1 is preferably provided with a water tank inlet pipeline 4. As shown in fig. 1, the limestone slurry may enter through a tank inlet conduit 4 in the bottom side wall of the tank 1. Meanwhile, in order to remove the impurities in the water tank 1 in time, as shown in fig. 1, a water tank sewage drain pipe 8 is preferably arranged at the bottom of the water tank 1. In addition, in order to effectively increase the capacity of the pool 1, the bell mouth opening of the water inlet 9 is preferably arranged at the position close to the bottom surface of the pool 1, so that more limestone slurry can be accommodated in the bell mouth opening of the water inlet 9.

The utility model discloses can effectively slow down the phenomenon that the pipeline is stifled, reduce equipment fault rate simultaneously, market promotion prospect is very wide.
