[0002] Quicklime is a production raw material in the construction industry. During the digestion process of quicklime, a large amount of steam is generated, and the steam contains fine particles of CaO and Ca(OH). 2 , the surface area of this dust is relatively large and can remain in the air for a long time. Therefore, there is an obvious smell of lime in the batching workshop and its surrounding areas. In severe cases, the visibility in this operation area is very low, and workers are greatly harmed when working here. The steel structure equipment is highly corroded in this area and is prone to uncontrollable failures. However, the existing digesters will have a relatively high dust concentration in the sintering batching area and the mixing belt corridor after digestion, which seriously endangers the physical health of on-site workers and fails to achieve a win-win benefit. Therefore, it is necessary to design a quicklime digestion device with a dust removal function and capable of controlling the mixing ratio of quicklime and water. Content of the Utility Model

[0003] Aiming at the above technical problems, the utility model provides a quicklime digestion device with a dust removal function and capable of controlling the mixing ratio of quicklime and water to solve the problems of damage to the air and equipment caused by the dust generated during the digestion reaction of quicklime.

In order to be able to measure the weight of the quicklime added to the digestion tank 1 and facilitate proportional control in the digestion chamber, gravity sensors 8 are fixedly connected to both sides of the outer bottom of the digestion tank 1. The other ends of the gravity sensors 8 are fixedly connected with the brackets. A water spray pipe 4 is fixedly connected to the left side of the digestion chamber 24. In order to make the sprayed water sprinkle more evenly on the quicklime, a nozzle 10 penetrating the side wall of the digestion chamber 24 is fixedly connected to the water spray pipe 4. In order to be able to remove the dust and large particle impurities generated in the digestion reaction, a dust outlet pipe 14 penetrating the side wall of the digestion chamber 24 is fixedly connected to the other side of the digestion chamber 24. The other end of the dust outlet pipe 14 is fixedly connected with the dust removal tank 13. The dust outlet pipe 14 is connected to the lower part of the left side wall of the dust removal tank 13. In order to achieve the filtering function, a baffle 18 is vertically arranged upward in the dust removal tank 13. The baffle 18 divides the dust removal tank 13 into two parts. The left side is a filtering chamber, and the right side is a purification chamber. The baffle 18 is not connected to the top of the dust removal tank 13. In order to filter the large particle impurities entering the water, a dust removal plate 19 is fixedly connected above the baffle 18. The other end of the dust removal plate 19 is fixedly connected with the top of the dust removal tank 13. In order to achieve the recycling of water and avoid waste, a water pipe 5 is fixedly connected to the rear of the purification chamber on the right side of the dust removal tank 13.

[0018] In order to preliminarily filter out the larger particle impurities generated in the digestion chamber 24, a filter screen 15 is fixedly connected to the end of the dust outlet pipe 14 connected to the side wall of the digestion chamber 24 to prevent large particle impurities from entering the dust outlet pipe 14 and causing blockage.

[0019] In order to be able to suck the large particle dust and impurities generated in the digestion tank 1 into the dust removal tank 13, an induced draft fan 12 is fixedly connected to the dust outlet pipe 14.

[0020] In order to collect the slaked lime after the reaction, discharge ports 6 are provided on both sides of the bottom of the digestion tank 1.

[0021] In order to keep the water in the left filtration chamber of the dust removal tank 13 in a full state to facilitate the filtration of impurities, a water inlet pipe 23 is fixedly connected to the top of the dust removal tank 13, and the water inlet pipe 23 continuously supplies water to the dust removal tank 13. And a starting and closing door is provided on one side of the filtration chamber to facilitate the cleaning after sufficient precipitation has accumulated in the filtration chamber.

[0022] The specific working process of the present utility model is as follows:

[0023] When the slaking reaction of quicklime is required, the quicklime is poured into the digestion tank 1 from the feed inlet 2. At this time, the large pieces of quicklime fall on the filter plate 7, and the cover plate above the feed inlet 2 is closed. At this time, the first motor 3 and the water pump 22 are started. The first motor drives the first stirring shaft 16 to rotate. The large pieces of quicklime are stirred by the stirring blades driven by the first stirring shaft 16 into fine particles, and fall into the lower digestion chamber 24 through the filter plate 7. The amount of water to be added in proportion is calculated by the gravity sensor 8. At the same time, the spray head 10 on the left side of the digestion chamber 24 starts to spray water, and at the same time, the second motor 9 is started to drive the second stirring shaft 11 to mix and stir the materials to help the slaking reaction of quicklime better. During the whole stirring process, the induced draft fan 12 is turned on to suck the hot air and large particle impurities generated in the digestion tank 1 into the left bottom of the dust removal tank 13. The water inlet pipe 23 continuously and slowly sends water into the left top of the dust removal tank 13. The small particle impurities and dust coming out of the dust outlet pipe 14 fall to the left bottom of the dust removal tank 13 for precipitation. The water on the left side flows into the right side of the dust removal tank 13 through the filtration of the dust removal plate 19, and then is connected to the water pipe 5 on the right side of the dust removal tank 13 to form a water cycle. The purified gas is discharged from the air outlet 17 at the top right of the dust removal tank 13. By carrying out the slaking of quicklime according to the above steps, the ratio of quicklime to water can be accurately controlled, better slaked lime can be obtained, and at the same time, the discharge of dust causing environmental pollution can be reduced.
