Description

Technical Field

[0001] The utility model relates to the technical field of sugar making equipment, in particular to a continuous sugar boiling tank. Background Art

[0002] At present, domestic sugar factories mainly use intermittent crystallizers to boil sugar. The boiling process of intermittent crystallizers is: feeding → cooling (or evaporation) → crystallization → discharging, that is, each time a can of sugar is boiled, it needs to be discharged once. The production process requires waiting time for feeding, discharging and cleaning, and the cycle is relatively long. If the output requirement is high, dozens or even hundreds of crystallizers are often required, which occupy a large area.

[0003] With the continuous development of sugar production technology, domestic sugar factories can also use continuous vacuum sugar boiling tanks. There are about 6-16 compartments in the vacuum sugar boiling tank. The flow of sugar paste is achieved through pressure difference between the compartments. For example, the invention patent application CN110791594A discloses a novel horizontal continuous crystallization tank with multiple independent chambers and a wheel washing control method thereof. The horizontal continuous crystallization tank has 3 to 4 independent closed chambers in the body, and each chamber is divided into 3 to 4 upper connected chambers by transverse partitions and longitudinal partitions. Chamber, a liquid downflow channel is formed between the heating body on both sides of each compartment and the wall of the crystallization tank, a forced agitator is installed at the bottom of the liquid downflow channel or the bottom of the heating body, each compartment has an independent seed feeding, water inlet and spray washing system, and the 2 to 4 upper connected compartments in each compartment share a vertical tubular heating body, a juice steam chamber, a juice catcher, a condenser, a sugar release valve device and a seed feed pipe, and each independently closed compartment is connected to each other by a gate valve, and the sugar paste can flow between the compartments. In addition, the invention patent application discloses that the fluidity of the sugar paste will deteriorate after the sugar paste is gradually concentrated. It uses different vacuum degrees to adjust different independent closed compartments, and gradually increases the vacuum degree. The pressure difference between the compartments is used to promote the orderly flow of the sugar paste between the compartments. This method can promote the flow and discharge of the sugar paste, but the vacuum is controlled separately, the line layout is more complicated, and the energy consumption is increased to a certain extent. Utility Model Content

[0005] To achieve the above purpose, the technical solution of the utility model is:

[0006] A continuous sugar-boiling tank comprises a long trough-shaped tank body, the tank body is provided with a transverse partition and a longitudinal partition, the tank body is divided into an independent left front chamber, a left rear chamber, a right front chamber and a right rear chamber, the sugar paste enters from the left rear chamber, passes through the left front chamber, the right front chamber, and finally flows out from the right rear chamber; a left heating body is provided in the left front chamber and the left rear chamber, and a right heating body is provided in the right front chamber and the right rear chamber; the top surface height of the right heating body is lower than the top surface height of the left heating body.

[0007] Furthermore, the left heating body and the right heating body adopt vertical tube-type heating bodies, in which a plurality of heating tubes are arranged, and the height of the heating tubes arranged in the right heating body is lower than the height of the heating tubes arranged in the left heating body.

[0010] Furthermore, the longitudinal partition completely separates the left heating body from the right heating body, and the right heating body includes a right front heating body and a right rear heating body, which are separated by the transverse partition, and the top surface height of the right rear heating body is lower than the top surface height of the right front heating body.

[0011] Furthermore, a left front heater air inlet pipe is provided on a side of the left front heater away from the right heater, and a left rear heater air inlet pipe is provided on a side of the left rear heater away from the right heater.

[0012] Furthermore, a right front heater air inlet pipe is provided on a side of the right front heater away from the left heater, and a right rear heater air inlet pipe is provided on a side of the right rear heater away from the left heater.

The left heating body and the right heating body can be respectively introduced with heating gases of different temperatures. The left heating body adopts heating gases of higher temperature, and the right heating body adopts second-effect and third-effect juice vapors of lower temperature. In this way, the concentration speeds of the left rear chamber, the left front chamber, the right front chamber, and the right rear chamber can be controlled respectively, so as to avoid excessive concentration of the massecuite in the right front chamber and the right rear chamber, which makes it difficult to lift the massecuite to the top surface of the right heating body due to the high concentration. At the same time, the second-effect and third-effect juice vapors can be reasonably used to achieve the purpose of reducing energy consumption. In addition, in this way, the top surface height of the right heating body can be better designed, so that it can meet the travel requirements of massecuite concentration and enable the massecuite before and after concentration to be lifted to the top surface of the right heating body.

[0028] A continuous sugar boiling tank, such as Figure 1-4 As shown (for easy viewing, Figure 1 and Figure 2Rotated 90° to the left), comprising a long trough-shaped tank body 10, the tank body 10 is provided with a transverse partition 7 and a longitudinal partition 9, which divide the tank body 10 into independent left front chamber 12, left rear chamber 11, right front chamber 13 and right rear chamber 14, the sugar paste enters from the left rear chamber 11, passes through the left front chamber 12, the right front chamber 13, and finally flows out from the right rear chamber 14; a left heating body 1 is provided in the left front chamber 12 and the left rear chamber 11, and a right heating body 5 is provided in the right front chamber 13 and the right rear chamber 14; the top surface height of the right heating body 5 is lower than the top surface height of the left heating body 1. Generally speaking, the bottom surfaces of the left heating body 1 and the right heating body 5 are on the same horizontal plane, combined with Figure 1 As shown, the top surface of the right heating body 5 is lower than the horizontal line where the top surface of the left heating body 1 is located. The separation mentioned here is that the longitudinal partition 9 separates the left front chamber 12, the left rear chamber 11 and the right front chamber 13, and the right rear chamber 14. The left heating body 1 and the right heating body 5 can be separated by the longitudinal partition 9 or not, but except for the positions of the left heating body 1 and the right heating body 5, the other spaces in the tank body 10 are separated, leaving only a passage for the sugar paste to move from the left front chamber 12 to the right front chamber 13. In addition, the left front chamber 12 and the left rear chamber 11 are separated by the transverse partition 7, and the left heating body 1 may be separated or not. However, for the left half of the tank body 10 separated by the longitudinal partition 9, except for the position of the left heating body 1, other spaces are separated, leaving only a passage for the sugar paste to flow from the left rear chamber 11 to the left front chamber 1. Similarly, the right front chamber 13 and the right rear chamber 14 are separated by the transverse partition 7, leaving only a passage for the sugar paste to flow from the right front chamber 13 to the right rear chamber 14. The setting of the transverse partition 7 and the passages for the sugar paste to flow between the chambers are the same as those in the prior art. According to the path along which the sugar paste moves, the concentration of the sugar paste in the left rear chamber 11, the left front chamber 12, the right front chamber 13 and the right rear chamber 14 gradually increases. When the sugar paste moves to the right front chamber 13 and the right rear chamber 14, the fluidity of the sugar paste will deteriorate due to the concentration in the left rear chamber 11 and the left front chamber 12. In this embodiment, the height of the right heating body 5 is adjusted to be lower than the height of the left heating body 1. Under the same vacuum degree, the sugar paste can also be lifted to the top of the right heating body 5 for circulation heating, thereby avoiding the problem that the sugar paste cannot be lifted to the top of the right heating body 5 for heating due to the deterioration of fluidity, resulting in unsatisfactory concentration effect of the sugar paste and difficulty in discharge.

[0029] Furthermore, the left heating body 1 and the right heating body 5 adopt a vertical tube-type heating body, which is a heating body form commonly used in the current continuous sugar-boiling pot. Each heating body 1 includes a heating body shell and a plurality of heating tubes. The top end of the heating tube is connected to the top surface of the heating body shell, and the bottom end is connected to the bottom surface of the heating body shell. The heating tube is a hollow round tube. The heating gas enters the heating body shell to heat the heating tube, and the heat is transferred to the sugar paste flowing in the heating tube. The sugar paste rises to the top of the heating body from other areas in the tank body 10 under the action of vacuum, enters the heating tube and descends, and repeats the cycle, thereby achieving the concentration of the sugar paste. Matching the top and bottom surfaces of the heating body shell, the bottom ends of the heating tubes generally arranged on the right heating body 5 and the left heating body 1 are on the same horizontal line, and the height of the heating tube arranged in the right heating body 5 is lower than the height of the heating tube arranged in the left heating body 1, so that the height of the sugar paste that needs to be lifted is reduced, which can effectively ensure that the sugar paste enters the heating tube for heating and concentration.

[0030] Furthermore, for the setting of the left heating body 1 and the right heating body 5, the present embodiment provides a more preferred solution, the longitudinal partition 9 completely separates the left heating body 1 and the right heating body 5, and the heating gases in the left heating body 1 and the right heating body 5 cannot be exchanged with each other; a left heating body air inlet pipe 2 is arranged on the side of the left heating body 1 away from the right heating body 5; a right heating body air inlet pipe 4 is arranged on the side of the right heating body 5 away from the left heating body 1, so that the left heating body 1 and the right heating body 5 can be respectively introduced with heating gases of different temperatures, the left heating body 1 adopts heating gases with higher temperature, and the right heating body 5 adopts two-effect and three-effect juice vapors with lower temperature, such as This can control the concentration speed of the left rear chamber 11, the left front chamber 12 and the right front chamber 13, the right rear chamber 14 respectively. The left rear chamber 11 and the left front chamber 12 concentrate faster, while the right front chamber 13 and the right rear chamber 14 concentrate slower, so as to avoid excessive concentration of massecuite in the right front chamber 13 and the right rear chamber 14, which makes it difficult to lift it to the top surface of the right heating body 5 due to too high concentration. At the same time, the second-effect and third-effect juice steam can be reasonably used to achieve the purpose of reducing energy consumption. In addition, in this way, the top surface height of the right heating body 5 can be better designed, so that it can meet the stroke requirements of massecuite concentration and can lift the massecuite before and after concentration to the top surface of the right heating body 5.

[0031] Furthermore, this embodiment provides a more preferred solution, in which the top surface height of the right heating body 5 is 5-30 mm lower than the top surface height of the left heating body 1 , which is mainly designed according to the volume of the tank body 10 and the concentration requirements of the sugar paste.

[0032] Furthermore, if the right heating body 5 and the left heating body 1 are vertical tube-type heating bodies, the top and bottom surfaces of the right heating body 5 and the left heating body 1 are matched, and the height of the heating tube arranged in the right heating body 5 is 5-30 mm lower than the height of the heating tube arranged in the left heating body 1.

[0033] Furthermore, the tank body 10 is also provided with a plurality of longitudinal sub-partitions 6, which further divide the left front chamber 12, the left rear chamber 11, the right front chamber 13 and the right rear chamber 14 into a plurality of compartments. As shown in the background technology, there are about 6-16 compartments in the vacuum sugar boiling tank. The left front chamber 12 and the left rear chamber 11 are separated by the same sub-partition 6. Similarly, the right front chamber 13 and the right rear chamber 14 are separated by the same sub-partition 6. However, the sub-partition 6 does not separate the left heating body 1 and the right heating body 5.

[0034] In the continuous sugar-boiling tank of the present embodiment, the heating gas enters the left heating body 1 and the right heating body 5, the sugar paste enters from the left rear chamber 11, passes through the left front chamber 12 and the right front chamber 13, and finally flows out from the right rear chamber 14. The sugar paste is heated and concentrated by the left heating body 1 in the left rear chamber 11 and the left front chamber 12, and is heated and concentrated by the right heating body 5 in the right front chamber 13 and the right rear chamber 14. The heating gas entering the left heating body 1 and the right heating body 5 becomes condensed water after cooling and is discharged from the condensed water outlet pipe 3 at the bottom of the left heating body 1 and the right heating body 5. The steam generated by the condensation of the sugar paste is discharged after passing through the juice catcher 8 at the top of the tank body 10. Embodiment 2

[0035] A continuous sugar-boiling tank comprises a long trough-shaped tank body 10, wherein the tank body 10 is provided with a transverse partition 7 and a longitudinal partition 9, and the tank body 10 is divided into an independent left front chamber 12, a left rear chamber 11, a right front chamber 13 and a right rear chamber 14. The sugar paste enters from the left rear chamber 11, passes through the left front chamber 12 and the right front chamber 13, and finally flows out from the right rear chamber 14; a left heating body 1 is provided in the left front chamber 12 and the left rear chamber 11, and a right heating body 5 is provided in the right front chamber 13 and the right rear chamber 14; the top surface height of the right heating body 5 is lower than the top surface height of the left heating body 1. Generally speaking, the bottom surfaces of the left heating body 1 and the right heating body 5 are on the same horizontal plane, and the left heating body 1 and the right heating body 5 are on the same horizontal plane. Figure 1 As shown, the top surface of the right heating body 5 is lower than the horizontal line where the top surface of the left heating body 1 is located. The separation mentioned here is that the longitudinal partition 9 separates the left front chamber 12, the left rear chamber 11 and the right front chamber 13, and the right rear chamber 14, including the left heating body 1 and the right heating body 5 are also separated by the longitudinal partition 9, leaving only a passage for the sugar paste to flow from the left front chamber 12 to the right front chamber 13.

[0036] Furthermore, the transverse partition 7 completely separates the left front chamber 12 and the left rear chamber 11, including the left heating body 1, leaving only a passage for the sugar paste to flow from the left rear chamber 11 to the left front chamber 1. The left heating body 1 includes a left front heating body and a left rear heating body, which are separated by the transverse partition 7, and the top surface height of the left front heating body is lower than the top surface height of the left rear heating body.

[0037] Furthermore, the transverse partition 7 also completely separates the right front chamber 13 and the right rear chamber 14, that is, the right heating body 5 is also separated, leaving only a passage for the right front chamber 13 of the sugar paste to move to the right rear chamber 14. The right heating body 5 includes a right front heating body and a right rear heating body, which are separated by the transverse partition 7, and the top surface height of the right rear heating body is lower than the top surface height of the right front heating body.

[0038] The concentration of the sugar paste in the left rear chamber 11, the left front chamber 12, the right front chamber 13 and the right rear chamber 14 increases gradually. This is because the sugar paste is heated and concentrated in each chamber. According to the path of the sugar paste, the fluidity of the sugar paste gradually deteriorates in the left front chamber 12, the right front chamber 13 and the right rear chamber 14. In this embodiment, the heights of the heating bodies are adjusted, and the height of the right heating body 5 is lower than that of the left heating body 1. More specifically, the heights of the heating bodies are arranged in the following order: left rear heating body>left front heating body>right front heating body>right rear heating body. In this way, even if the fluidity of the sugar paste deteriorates, under the same vacuum degree, the sugar paste can be lifted to the top of the left front heating body, the right front heating body and the right rear heating body for cyclic heating, thereby avoiding the problem that the sugar paste cannot be heated by the left front heating body, the right front heating body and the right rear heating body due to poor fluidity, resulting in unsatisfactory concentration effect and difficulty in discharge of the sugar paste.

[0039] Furthermore, a left front heater air inlet pipe is provided on the side of the left front heater away from the right heater 5, and a left rear heater air inlet pipe is provided on the side of the left rear heater away from the right heater 5. By respectively introducing heating gases of different temperatures into the left front heater air inlet pipe and the left rear heater air inlet pipe, the concentration speeds of the left rear chamber 11 and the left front chamber 12 can be controlled respectively, and the left rear chamber 11 concentrates faster than the left front chamber 12, so as to avoid excessive concentration of the massecuite in the left front chamber 12, which makes it difficult to lift it to the top surface of the left front heater due to too high concentration. The top surface height of the left front heater can also be better designed so that it can meet the travel requirements of massecuite concentration and can lift the massecuite before and after concentration to the top surface of the left front heater.

[0040] Furthermore, the same is true for the arrangement of the right front heater and the right rear heater. A right front heater air intake pipe is arranged on the side of the right front heater away from the left heater 1, and a right rear heater air intake pipe is arranged on the side of the right rear heater away from the left heater 1. The right front heater air intake pipe and the right rear heater air intake pipe can introduce two-effect and three-effect juice steam respectively. In this way, the two-effect and three-effect juice steam are reasonably used to achieve the purpose of reducing energy consumption.
