The purpose of this utility model is to solve the existing problems, and provide a simple structure, which can recycle the heat generated during digestion, and use the recovered heat to heat cold water and then carry out hot water digestion, so as to improve the digestion speed of calcium oxide and improve the Energy-saving and high-efficiency calcium oxide digestion unit for production efficiency.

The technical solutions of the present utility model are as follows:

An energy-saving and high-efficiency calcium oxide digestion device, comprising a box, the side of the box is provided with a feed port, the bottom of the box is provided with a discharge port, the top of the discharge port is provided with a first water inlet pipe, the The top of the box is fixed with a cylinder connected to the box, and a spiral pipe is arranged in the cylinder, the upper end of which passes through the cylinder to connect with the tap water pipe, and the lower end of the pipeline passes through the cylinder and extends to the top of the inner cavity of the box , The box is also equipped with a crushing and stirring device.

Preferably, a spray head is fixed on the port of the pipeline in the box.

Preferably, the crushing and stirring device includes two rotating shafts that turn in opposite directions, and multiple sets of propeller-shaped blades are fixed on the rotating shafts.

Preferably, a detachable filter is provided at the outlet.

Preferably, a temperature detector for measuring the internal temperature of the cylinder is also installed on the cylinder.

The beneficial effect of the utility model lies in that: the structure is simple, the heat generated during digestion can be recycled, and the recovered heat is used to heat cold water and then carry out hot water digestion, so as to improve the digestion speed of calcium oxide and improve production efficiency.

detailed description:

As shown in Figure 1, the energy-saving and high-efficiency calcium oxide digestion device comprises a casing 1, the side of the casing 1 is provided with a feed port 2, and the bottom of the casing 1 is provided with a discharge port 3, and the discharge port 3 A first water inlet pipe 4 is provided above, and a cylinder 5 communicating with the tank 1 is fixed on the top of the tank 1. A spiral pipe 6 is arranged inside the cylinder 5, and the upper end of the pipe 6 passes through the cylinder. The body 5 is connected with the tap water pipe, and the lower end passes through the cylinder body 5 and extends to the top of the inner cavity of the box body 1, and a crushing and stirring device is also installed in the box body 1.

Specifically, the nozzle 7 is fixed on the port of the pipeline 6 in the box body 1, and this setting can evenly spray the hot water in the pipeline 6 on the calcium oxide, so that the digestion effect is better.

Specifically, the crushing and stirring device includes two rotating shafts 8 that turn in opposite directions. There are multiple sets of propeller-shaped blades 9 fixed on the rotating shafts 8. This setting can not only crush the blocky calcium oxide, but also play a role in stirring during the digestion process. The role of milk of lime.

Specifically, the discharge port 3 is provided with a detachable filter screen, which can filter the waste residue to ensure the purity of the lime milk when the lime milk is sucked out under negative pressure.

Specifically, a temperature detector 10 for measuring the internal temperature of the cylinder 5 is also installed on the cylinder 5 .

The working principle of the utility model: Calcium oxide falls into the box body 1 from the feed port 2, and is broken by the blade 9. First, the first water inlet pipe 4 is filled with tap water. At this time, the heat generated by digestion enters the barrel body 5, Pipeline 6 is pre-filled with tap water. After the digestion reaction takes 10 to 20 minutes, the heat generated heats up the tap water in pipe 6, and then the hot water in pipe 6 is sprayed into box 1 through nozzle 7 to carry out the next wave of digestion reaction At this time, the pipeline 6 is filled with tap water again, so that the heat can be continuously recycled to achieve the purpose of energy saving. Digesting calcium oxide with hot water saves 20% to 30% of the time compared with cold water digestion, and the production efficiency is obvious. improve.

The above descriptions are only preferred embodiments of the present utility model, and all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.
