[0007] A lime digestion device comprises an outer shell, a cover plate, a high-pressure nozzle and a hollow tube, wherein the cover plate is installed at the top of the outer shell, the interior of the outer shell is provided with a hollow tube, the high-pressure nozzle is inserted into the hollow tube, the end of the high-pressure nozzle located on one side of the outer shell is provided with a flange, the flange is connected to a cone block, a motor is installed at the bottom end of the outer shell, a fixed shaft is provided at the output end of the motor, and a stirring blade is installed on the fixed shaft.
[0008] On the basis of the above technical solution, the present invention can also be improved as follows.
[0009] Furthermore, the cover plate is provided with a threaded tube, the threaded tube is provided with threads, and the cover plate is connected and fixed to the shell through the threads of the threaded tube.
[0010] The beneficial effects of adopting the above further scheme are:

The design of the threaded tube and thread makes it easier to connect and disassemble the cover and the shell. When maintenance, replacement or cleaning is required, the threaded tube can be easily unscrewed and the cover can be removed, making maintenance and repair work more convenient.
[0012] Furthermore, the cone block is cone-shaped. When the raw material is discharged through the cone block, the raw material can be guided by the cone block. A connecting shaft is provided at the bottom end of the cone block, a stopper is provided at the end of the connecting shaft, and the connecting shaft passes through the flange. The cone block is installed on the flange through the connecting shaft, and the lifting distance of the connecting shaft is limited by the stopper, thereby limiting the displacement distance of the cone block.
[0013] The beneficial effects of adopting the above further scheme are:
[0014] The design of the conical block can guide the raw materials as they pass through the block, helping to control the flow direction and distribution of the raw materials and improve the accuracy and consistency of raw material processing. The design of the stopper can easily control the displacement distance of the cone block, thereby improving the stability of the entire structure.
[0015] Furthermore, a connecting rod is provided on the fixed shaft, and the stirring blade is connected and fixed on the fixed shaft through the connecting rod. The beneficial effects of adopting the above further solution are:
[0016] By setting a connecting rod on the fixed shaft, the stirring blade can be simply connected to the fixed shaft, avoiding the use of complex fixing devices, reducing the difficulty and cost of connection.

This makes maintenance and repair more convenient.
[0017] Furthermore, one end of the high-pressure nozzle facing away from the cone block is connected to a high-pressure water pump, and a high-pressure water source is pumped into the high-pressure nozzle by the high-pressure water pump, and is blocked by the cone block, so that water is sprayed out from the gap between the cone block and the flange to form a water curtain, thereby blocking the dust of the raw materials below and preventing the dust from being dispersed from the feed inlet.
[0018] The beneficial effects of adopting the above further scheme are:
[0019] The design of the high-pressure nozzle and the cone block allows water to be sprayed out from the gap between the cone block and the flange to form a water curtain, effectively blocking and suppressing the dust from the raw materials below, improving the dust suppression effect. At the same time, after the water flows into the inner wall of the shell, it flows down along the inner wall and mixes with the raw materials.

[0022] Since the motor is located at the bottom of the housing, the stirring blades can stir the materials in the entire housing evenly from the bottom to the top. In this way, the materials in the housing can be mixed or dispersed more effectively and the stirring effect can be improved. This design helps to evenly distribute the rotational force generated by the stirring blades driven by the motor to all corners of the housing. This can promote faster and more even mixing of the materials in the housing and reduce the phenomenon of uneven mixing.
[0023] Furthermore, the bottom end of the shell is provided with support columns, the support columns are evenly distributed at the bottom end of the shell, and the shell is supported by the support columns.
[0024] The beneficial effects of adopting the above further scheme are:

The support column can provide a stable support point, making the device more stable when placed and not prone to tilting or shaking. The support column can provide sufficient strength and stability so that the housing can withstand greater weight. The setting of the support column makes the bottom of the stirring device more open, which is convenient for maintenance and cleaning.
[0026] The beneficial effects of the utility model are:
[0027] 1. The device effectively prevents dust from raw materials through the water curtain formed by the hollow tube and high-pressure water spray, thus improving the hygiene and safety of the working environment.
[0028] 2. The cone block can guide the raw materials well, ensuring that the raw materials enter the correct position of the equipment, thereby improving the working efficiency and output of the equipment.
[0029] 3. The stirring blades output by multiple motors increase the stirring range inside the equipment, so that the raw materials and spray water are evenly mixed, improving the efficiency and uniformity of lime digestion.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0040] See also Figures 1 to 4 As shown, the embodiments provided by the utility model:
[0041] Embodiment 1
[0042] A lime digestion device comprises a shell 2, a cover plate 3, a high-pressure nozzle 4 and a hollow tube 9. The bottom end of the shell 2 is provided with a support column 1, which is evenly distributed at the bottom end of the shell 2. The shell 2 is supported by the support column 1. By arranging the support column 1 at the bottom end of the shell 2, the stability of the device can be increased. The support column 1 can provide a stable support point, so that the device is more stable when placed and is not easy to tilt or shake. The support column 1 can provide sufficient strength and stability, so that the shell 2 can bear a larger weight. The arrangement of the support column 1 makes the bottom of the stirring device more open, which is convenient for maintenance and cleaning. The top end of the shell 2 is provided with a cover plate 3, and the cover plate 3 is provided with a threaded pipe 7, and the threaded pipe 7 is provided with a thread. The cover plate 3 is connected and fixed to the shell 2 through the thread of the threaded pipe 7. The design of the threaded pipe 7 and the thread can realize reliable connection and fixation between the cover plate 3 and the shell 2, avoid the cover plate 3 from loosening or falling off during use, and improve the stability of the whole machine. The design of the threaded pipe 7 and the thread makes the connection and disassembly between the cover plate 3 and the shell 2 more convenient. When maintenance, replacement or cleaning is required, the threaded tube 7 can be easily unscrewed and the cover plate 3 can be removed, making maintenance and overhaul work more convenient.
[0043] A hollow tube 9 is provided inside the shell 2, and a high-pressure nozzle 4 is inserted in the hollow tube 9. The end of the high-pressure nozzle 4 away from the cone block 11 is connected to the high-pressure water pump. The high-pressure water source is pumped into the high-pressure nozzle 4 by the high-pressure water pump, and is blocked by the cone block 11, so that the water is sprayed out from the gap between the cone block 11 and the flange 12 and forms a water curtain, thereby blocking the dust of the raw materials below and preventing the dust from being dispersed from the feed port 6. The design of the high-pressure nozzle 4 with the cone block 11 can make the water source spray out from the gap between the cone block 11 and the flange 12 and form a water curtain, effectively blocking and suppressing the dust of the raw materials below, and improving the dust suppression effect. At the same time, after the water flow contacts the inner wall of the shell 2, it flows down along the inner wall and mixes with the raw materials. By adjusting the pumping amount of the high-pressure water pump, the thickness and water volume of the water curtain can be flexibly controlled to adapt to different dust suppression requirements and process conditions.
[0044] The end of the high-pressure nozzle 4 located on one side of the housing 2 is provided with a flange 12, and a cone block 11 is connected to the flange 12. The cone block 11 is conical. When the raw material is discharged through the cone block 11, the raw material can be guided by the cone block 11. The design of the conical cone block 11 can guide the raw material when passing through the cone block 11, which helps to control the flow direction and distribution of the raw material and improve the accuracy and consistency of raw material processing. The design of the stopper 10 can easily control the displacement distance of the cone block 11, thereby improving the stability of the entire structure. The bottom end of the cone block 11 is provided with a connecting shaft 15, and the end of the connecting shaft 15 is provided with a stopper 10, and the connecting shaft 15 passes through the flange 12. The cone block 11 is plugged and installed on the flange 12 through the connecting shaft 15, and the lifting distance of the connecting shaft 15 is limited by the stopper 10, thereby limiting the displacement distance of the cone block 11.
[0045] The bottom end of the shell 2 is equipped with a motor 5, which is evenly distributed at the bottom end of the shell 2, so that it is convenient to increase the stirring range in the shell 2 through the stirring blade 14 at the output end of the motor 5. Since the motor 5 is distributed at the bottom of the shell 2, the stirring blade 14 can evenly stir the material in the entire shell 2 from the bottom to the top. In this way, the material in the shell 2 can be mixed or dispersed more effectively, and the stirring effect can be improved. This design helps to evenly distribute the rotational force generated by the stirring blade 14 driven by the motor 5 to all corners of the shell. This can promote the material in the shell to mix faster and more evenly, and reduce the phenomenon of uneven mixing. The output end of the motor 5 is provided with a fixed shaft 8, and the stirring blade 14 is installed on the fixed shaft 8. The fixed shaft 8 is provided with a connecting rod 13, and the stirring blade 14 is connected and fixed to the fixed shaft 8 through the connecting rod 13. By arranging the connecting rod 13 on the fixed shaft 8, the stirring blade 14 can be simply connected to the fixed shaft 8, avoiding the use of complex fixing devices, and reducing the difficulty and cost of connection. Since the stirring blade 14 is connected to the fixed shaft 8 via the connecting rod 13, the stirring blade 14 can be easily replaced without disassembling the entire stirrer, which makes maintenance and repair more convenient.
