Description

Technical Field

[0001] This utility model relates to the field of sugar production technology, and in particular to a self-cleaning sugar boiling tank. Background Technology

[0002] The sugar boiling section is where the syrup from the evaporation and concentration in the sugar boiling tank is boiled into a sugar paste containing a large amount of uniform, perfectly clear, high-purity white sugar crystals. It is a process of concentrating and crystallizing syrup or molasses in the tank to form a paste-like sugar paste (crystals, mother liquor). It is the section that directly affects the quality of the final product of the sugar factory, and it is also the most important and complex section.

[0003] After the sugar is unloaded from the sugar boiling tank, it is necessary to clean the residual sugar paste inside the tank to avoid affecting the quality of subsequent products. Currently, this is usually done by pumping in a large amount of water or directly turning on a large amount of steam to completely dissolve the residual sugar paste. However, the annular spray pipe is installed inside the juice trap and is fixed in place, making it difficult to thoroughly clean the sugar paste on the surface of the steam drum. Therefore, a large amount of water or steam is required to thoroughly clean the sugar boiling tank, which is a waste of resources. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a self-cleaning sugar boiling tank that can thoroughly clean the tank, ensuring the quality of subsequent products.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A self-cleaning sugar boiling pot includes a pot body, a steam drum at the bottom of the pot body, which injects heating steam through a steam pipe to provide heat; a juice trap at the top of the pot body, which extracts the juice vapor generated by the evaporation of sugar juice through a vacuum tube; and a stirring mechanism, which includes a connecting shaft, stirring blades, and a drive motor. The connecting shaft is rotatably connected to the top of the pot body, with one end of the connecting shaft located inside the pot body and connected to the stirring blades, and the other end extending outside the pot body and being driven by the drive motor.

[0007] The connecting shaft and the stirring blade are hollow structures, and the connecting shaft and the stirring blade are interconnected. A first steam-water branch pipe is provided at the end of the connecting shaft away from the stirring blade. One end of the first steam-water branch pipe is rotatably connected to the connecting shaft through a bearing, and the first steam-water branch pipe is connected to the connecting shaft. The other end of the first steam-water branch pipe is connected to the steam-water main pipe. The stirring blade is provided with a first flushing hole so that the cleaning medium of the steam-water main pipe can pass through the connecting shaft and the stirring blade in sequence and then be discharged through the first flushing hole.

[0008] Furthermore, the stirring blade includes a plurality of stirring rods, which are arranged alternately around the connecting shaft, and one end of each stirring rod is fixedly connected to the connecting shaft and communicates with the connecting shaft. The first flushing hole is located on the side of the stirring rod facing away from the connecting shaft.

[0009] Furthermore, the drive motor is fixedly connected to the tank body, the output shaft of the drive motor is provided with a first transmission disk, and the outer wall of the connecting shaft is fixedly sleeved with a second transmission disk, and the first transmission disk is connected to the second transmission disk through a transmission belt.

[0010] Furthermore, the tank is also provided with a flushing pipe, and a plurality of second flushing holes are evenly spaced on the side wall and bottom of the flushing pipe. The flushing pipe is a ring structure with both ends closed, and one end of the flushing pipe is connected to the tank, and the other end is provided with a second steam and water branch pipe. One end of the second steam and water branch pipe is connected to the flushing pipe, and the other end extends out to the outside of the tank and is connected to the steam and water main pipe.

[0011] Furthermore, one end of the rinsing pipe is connected to the tank via an electric telescopic rod, and the other end of the rinsing pipe is connected to the second steam and water branch pipe via a spiral telescopic pipe; a cleaning brush is fixedly installed on the side of the rinsing pipe facing the juice trap.

[0012] Furthermore, the width of the flushing pipe is greater than the width of the stirring blade.

[0013] Furthermore, the first steam-water branch pipe, the second steam-water branch pipe, and the main steam-water pipe are all equipped with inlet valves.

[0014] Furthermore, a drain pipe is provided at the bottom of the tank, and a drain valve is provided on the drain pipe.

[0015] The beneficial effects of this utility model are:

[0016] 1. The drive motor drives the connecting shaft to rotate, allowing the stirring blades to rotate inside the tank. Due to the bearings, the connecting shaft can rotate relative to the first steam-water branch pipe, allowing the cleaning medium from the main steam-water pipe to pass through the connecting shaft and the stirring blades in sequence before being discharged through the first flushing hole. At the same time, the rotation of the stirring blades ensures that the cleaning medium can thoroughly flush the steam drum, improving the cleaning effect of the steam drum, ensuring the quality of subsequent products, and eliminating the need for large amounts of water or steam to thoroughly clean the sugar boiling tank, avoiding resource waste and effectively reducing production costs.

[0017] 2. The electric telescopic rod allows the flushing pipe to move within the tank. The cleaning medium in the main steam and water pipe can pass sequentially through the second steam and water branch pipe and the flushing pipe before being discharged through the second flushing hole. Since the second flushing hole is located on the side wall and bottom of the flushing pipe, the cleaning medium discharged from the second flushing hole can clean and flush the side wall of the tank and the steam drum during the up-and-down movement of the flushing pipe. At the same time, the cleaning brush can sweep and brush the steam drum during the movement of the flushing pipe, effectively improving the cleaning efficiency of the steam drum and thoroughly cleaning the surface of the steam drum, avoiding the residue of sugar paste in the dead corners of the steam drum.

[0026] Please also see Figures 1 to 4 A preferred embodiment of the present invention provides a self-cleaning sugar boiling tank, comprising a tank body 1, a steam drum 11 at the bottom of the tank body 1, which injects heating steam through a steam pipe to provide heat; and a juice trap 12 at the top of the tank body 1, which extracts the juice vapor generated by the evaporation of sugar juice through a vacuum tube.

[0027] It also includes a stirring mechanism, which comprises a connecting shaft 2, a stirring blade 21, and a drive motor 22. The connecting shaft 2 is rotatably connected to the top of the tank 1, with one end of the connecting shaft 2 located inside the tank 1 and connected to the stirring blade 21, and the other end extending out of the tank 1 and being driven by the drive motor 22. In this embodiment, the connecting shaft 2 is rotatably connected to the tank 1 via a sealed bearing.

[0028] The connecting shaft 2 and the stirring blade 21 are hollow structures, and the connecting shaft 2 and the stirring blade 21 are interconnected. A first steam-water branch pipe 3 is provided at the end of the connecting shaft 2 away from the stirring blade 21. One end of the first steam-water branch pipe 3 is rotatably connected to the connecting shaft 2 via a bearing 31, and the first steam-water branch pipe 3 is connected to the connecting shaft 2. The other end of the first steam-water branch pipe 3 is connected to the steam-water main pipe 4. The stirring blade 21 is provided with a first flushing hole 212, so that the cleaning medium in the steam-water main pipe 4 can pass through the connecting shaft 2 and the stirring blade 21 in sequence and then be discharged through the first flushing hole 212. In this embodiment, the bearing 31 is a pipe rotary bearing. The outer ring of the bearing 31 is fixedly connected to the connecting shaft 2, and the inner ring of the bearing 31 is fixedly connected to the first steam-water branch pipe 3. The cleaning medium is high-pressure steam or hot water. In this embodiment, the cleaning medium of the annular spray pipe above the juice trap 12 can pass through the steam-water main pipe 41.

[0029] A drain pipe 7 is provided at the bottom of the tank body 1, and a drain valve 71 is provided on the drain pipe 7. By opening the drain valve 71, the cleaning medium in the tank body 1 can be discharged through the drain pipe 7.

[0030] like Figure 1 As shown, the drive motor 22 is fixedly connected to the tank body 1. The output shaft of the drive motor 22 is equipped with a first transmission disk 231, and a second transmission disk 232 is fixedly sleeved on the outer wall of the connecting shaft 2. The first transmission disk 231 is connected to the second transmission disk 232 via a transmission belt 23. The drive motor 22 drives the first transmission disk 231 to rotate, and the first transmission disk 231 drives the second transmission disk 232 to rotate via the transmission belt 23. The second transmission disk 232 drives the stirring blade 21 to rotate via the connecting shaft 2, thereby realizing the stirring of materials.

[0031] like Figure 2 As shown, the stirring blade 21 includes several stirring rods 211, which are arranged alternately around the connecting shaft 2. One end of each stirring rod 211 is fixedly connected to the connecting shaft 2 and communicates with it. The first flushing hole 212 is located on the side of the stirring rod 211 facing away from the connecting shaft 2. In this embodiment, the rotation of the drive motor 22 is reduced during cleaning, and the stirring mechanism can simultaneously stir the material and clean the air drum 11.

[0032] In this embodiment, the drive motor 22 drives the connecting shaft 2 to rotate, so that the stirring blade 21 can rotate inside the tank 1. Under the action of the bearing 31, the connecting shaft 2 can rotate relative to the first steam-water branch pipe 3, so that the cleaning medium of the steam-water main pipe 4 can pass through the connecting shaft 2 and the stirring blade 21 in sequence and be discharged from the first flushing hole 212. At the same time, the rotation of the stirring blade 21 allows the cleaning medium to fully flush the steam drum 11, improving the cleaning effect of the steam drum 11, ensuring the quality of subsequent products, and thoroughly cleaning the sugar boiling tank without a large amount of water or steam, avoiding waste of resources and effectively reducing production costs.

[0033] like Figure 1 and Figure 2 As shown, the tank body 1 is also provided with a flushing pipe 5. The flushing pipe 5 has a plurality of second flushing holes 501 evenly spaced on its side wall and bottom. The flushing pipe 5 is a ring structure with both ends closed. One end of the flushing pipe 5 is connected to the tank body 1, and the other end is provided with a second steam and water branch pipe 51. One end of the second steam and water branch pipe 51 is connected to the flushing pipe 5, and the other end extends out to the outside of the tank body 1 and is connected to the steam and water main pipe 4.

[0034] like Figure 1 and Figure 4As shown, one end of the rinsing pipe 5 is connected to the tank 1 via an electric telescopic rod 52, and the other end of the rinsing pipe 5 is connected to the second steam-water branch pipe 51 via a spiral telescopic pipe 53. A cleaning brush 54 is fixedly installed on the side of the rinsing pipe 5 facing the juice trap 12. In this embodiment, the electric telescopic rod 52 is fixedly inserted into the tank 1, and the motor end of the electric telescopic rod 52 is located outside the tank 1. The electric telescopic rod 52 is fixedly connected to the rinsing pipe 5 via a connector 521. The spiral telescopic pipe 53 can move and extend in coordination with the rinsing pipe 5, thereby avoiding affecting product production.

[0035] The electric telescopic rod 52 allows the flushing pipe 5 to move within the tank 1. The cleaning medium from the main steam-water pipe 4 passes sequentially through the second steam-water branch pipe and the flushing pipe 5 before being discharged through the second flushing hole 501. Since the second flushing hole 501 is located on the side wall and bottom of the flushing pipe 5, the cleaning medium discharged from the second flushing hole 501 cleans and flushes the side wall of the tank 1 and the steam drum 11 during the up-and-down movement of the flushing pipe 5. Simultaneously, the cleaning brush 54 sweeps and brushes the steam drum 11 during the movement of the flushing pipe 5, effectively improving the cleaning efficiency of the steam drum 11 and thoroughly cleaning its surface, preventing sugar residue from remaining in the dead corners of the steam drum 11. The cleaning brush 54 is equipped with a connecting ring 541, which is fixedly connected to the flushing pipe 5.

[0036] like Figure 1 As shown, the first steam-water branch pipe 3, the second steam-water branch pipe 51, and the steam-water main pipe 4 are all equipped with inlet valves 6. By controlling the opening and closing of the inlet valves 6, the cleaning medium can be discharged into the connecting shaft 2 and the flushing pipe 5.

[0037] Preferably, the width of the rinsing pipe 5 is greater than the width of the stirring blade 21 to ensure that the raising and lowering of the rinsing pipe 5 does not conflict with the rotation of the stirring blade 21. At the same time, the cleaning medium discharged from the first rinsing hole 212 can rinse the cleaning brush 54 to prevent sugar paste residue from remaining in the cleaning brush 54.

[0038] The cleaning process of the self-cleaning sugar boiling tank in this embodiment is as follows:

[0039] The cleaning medium from the main steam-water pipe 4 passes sequentially through the first steam-water branch pipe 3, the connecting shaft 2, and the stirring blade 21 before being discharged through the first flushing hole 212. Simultaneously, the drive motor 22 drives the connecting shaft 2 to rotate, causing the cleaning medium to continuously flush the steam drum 11 in a rotating manner. The cleaning medium from the main steam-water pipe 4 can also pass sequentially through the second steam-water branch pipe and the flushing pipe 5 before being discharged through the second flushing hole 501. Simultaneously, the electric telescopic rod 52 is controlled to reciprocate, raising and lowering. The cleaning medium discharged from the second flushing hole 501 cleans and flushes the side walls of the tank 1 and the steam drum 11. Furthermore, the cleaning brush 54 sweeps and brushes the steam drum 11 as the flushing pipe 5 moves. After cleaning the tank 1, the drain valve 71 is opened, allowing the cleaning medium inside the tank 1 to be discharged through the drain pipe 7.
