Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a transmission heating system. Background Technology

[0002] Two key indicators require special attention during the sugar addition process: the accuracy of the addition and the temperature of the syrup. Previously, the temperature of the syrup in the mobile tank was maintained at the process standard temperature in the sugar preparation room. Although the sugar tank has insulation, the temperature will still drop if stored for too long after preparation. Even if the prepared syrup is used immediately, the temperature may still decrease in the middle and later stages of the application process, failing to meet process requirements. Because the mobile tank lacks a heating system, it cannot heat the syrup, making it impossible to ensure the syrup temperature meets process requirements during actual application. Furthermore, the lack of local heating at the addition point causes the syrup temperature to gradually decrease during batch production, failing to meet the standard temperature requirements.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein.

[0038] Figure 1 This is a schematic diagram of the overall structure of a heat transfer system according to an embodiment of the present invention. Figure 2This is a partial structural schematic diagram of a heat transfer system according to an embodiment of the present invention. Figure 3 This is a connection diagram of a heating device according to an embodiment of the present utility model. Figure 1 , Figure 2 and Figure 3 As shown, the heat transfer system includes:

[0039] Sugar material mobile tank 1, sugar material feeding tank 2, and heating device 3;

[0040] The sugar material transfer tank 1 is connected to the sugar material feeding tank 2 via a pipeline 4, which is used to transfer sugar material into the sugar material feeding tank 2;

[0041] Heating device 3 includes heating control unit 31 and heating sleeve 32; heating control unit 31 includes heating control terminal a; heating sleeve 32 includes heating receiving terminal b; heating control terminal a and heating receiving terminal b are electrically connected.

[0042] The heating sleeve 32 is fixedly sleeved on the pipe 4.

[0043] The sugar transfer tank 1 serves as a device for storing and transporting sugar, and can be used to transport the sugar in the sugar transfer tank 1 to the sugar feeding tank 2 for sugar addition. The sugar in the sugar transfer tank 1 is prepared according to the process temperature standard and needs to be transferred to the sugar feeding tank 2 for use in a timely manner. However, during the sugar addition process in the sugar transfer tank 1, the sugar temperature inevitably drops. Therefore, a heating device 3 is installed on the pipeline 4 between the sugar transfer tank 1 and the sugar feeding tank 2.

[0044] The heating device 3 includes a heating control unit 31, which controls the working state of the heating sleeve 32. The heating sleeve 32 is fixedly sleeved on the pipeline 4 and can heat the pipeline 4. Therefore, it can adjust the temperature of the sugar in the sugar moving tank 1 during the transfer to the sugar feeding tank 2, thereby solving the problem of temperature drop and ensuring the temperature requirements of the sugar.

[0045] The heating control unit 31 includes a heating control terminal a, which can output a heating start signal to the heating receiving terminal b. After receiving the heating start signal from the heating receiving terminal b, the heating sleeve 32 heats the sugar flowing through the heating sleeve 32, thereby increasing the temperature of the sugar received in the sugar feeding tank 2 and ensuring the process requirements.

[0046] For example, such as Figure 1As shown, the transfer heating system includes a sugar transfer tank 1 and a sugar feeding tank 2, which are connected by a pipeline 4. The sugar in the sugar transfer tank 1 is transferred to the sugar feeding tank 2 through the pipeline 4. A heating sleeve 32 is installed on the pipeline 4 and is fixedly sleeved on the pipeline 4. During the transfer of the sugar from the sugar transfer tank 1 to the sugar feeding tank 2 along the pipeline 4, the sugar is heated by the heating sleeve 32, thereby ensuring that the sugar entering the sugar feeding tank 2 meets the standard temperature requirements.

[0047] The technical solution of this utility model embodiment is to install a heating sleeve 32 on the connecting pipe 4 between the sugar material moving tank 1 and the sugar material feeding tank 2, and control the heating of the heating sleeve 32 to control the temperature of the sugar material transmitted in the sugar material feeding tank 2. This achieves controllable sugar material temperature, ensures that the sugar material temperature is maintained within the standard temperature range during the feeding process, meets the process quality requirements, and guarantees product quality.

[0048] Optional, continue to refer to Figure 1 . Figure 2 and Figure 3 As shown, the heating device 3 also includes fixing bolts 5;

[0049] The heating sleeve 32 is fixed to the pipe 4 by fixing bolts 5;

[0050] The heating receiver b is located at one end of the heating sleeve 32.

[0051] The fixing bolts 5 securely connect the heating sleeve 32 and the pipe 4. To ensure the connection between the fixing bolts 5 and the pipe 4, fixing bolts 5 can be installed at both ends of the heating sleeve 32 to fix it at both ends. The heating control terminal a is located at one end of the heating sleeve 32. The heating control terminal a can be used to connect the lead wire, and then connect to the heating control terminal a of the heating control unit 31.

[0052] For example, such as Figure 2 As shown, the heating sleeve 32 is fitted onto the pipe 4, and the heating sleeve 32 heats the pipe 4, thereby ensuring that the sugar flowing through this section of the pipe 4 is uniformly heated to the preset temperature. The heating sleeve 32 is fixed to the pipe 4 by fixing bolts 5 at both ends. The heating receiving end b of the heating sleeve 32 is electrically connected to the heating control end a of the heating control unit 31 via a lead wire.

[0053] The technical solution of this utility model embodiment is to fix the heating sleeve 32 to the pipeline 4 by setting the fixing bolt 5 in the heating device 3, thereby ensuring the installation and fixation of the heating sleeve 32 and improving the stability and reliability of the heating sleeve 32.

[0054] Optionally, the distance between the heating sleeve 32 and the sugar moving tank 1 is greater than the distance between the heating sleeve 32 and the sugar feeding tank 2.

[0055] The distance between the heating sleeve 32 and the sugar moving tank 1 can be the same as the distance of the pipeline 4 between them, and the distance between the heating sleeve 32 and the sugar feeding tank 2 can also be the same as the distance of the pipeline 4 between them. Setting the distance between the heating sleeve 32 and the sugar moving tank 1 to be greater than the distance between the heating sleeve 32 and the sugar feeding tank 2 aims to place the installation position of the heating sleeve 32 as close as possible to the sugar feeding tank 2, ensuring heating effectiveness and maximizing the heating effect during cyclic heating.

[0056] It is understandable that the distance between the heating sleeve 32 and the sugar moving tank 1 is set to be greater than the distance between the heating sleeve 32 and the sugar feeding tank 2, so that the sugar after passing through the heating sleeve 32 can be transferred to the sugar feeding tank 2 more quickly, ensuring the temperature of the sugar in the sugar feeding tank 2, preventing secondary temperature loss of the heated sugar due to the long transmission distance, and ensuring the heating effect of the heating sleeve 32.

[0057] The technical solution of this utility model embodiment sets the distance between the heating sleeve 32 and the sugar material moving tank 1 to be greater than the distance between the heating sleeve 32 and the sugar material feeding tank 2, so that the sugar material heated by the heating sleeve 32 is quickly transferred to the sugar material feeding tank 2, ensuring the heating effect in the cyclic heating process, meeting the process quality requirements, and ensuring product quality.

[0058] Optional, continue to refer to Figure 1 As shown, pipeline 4 includes a transmission inlet c and a transmission outlet d;

[0059] The transmission inlet c is connected to the sugar material moving tank 1; the transmission outlet d is connected to the sugar material feeding tank 2.

[0060] The heating sleeve 32 is located at the transmission outlet d.

[0061] Pipeline 4 includes a transmission inlet c and a transmission outlet d. Sugar flows from transmission inlet c to transmission outlet d. Transmission inlet c is connected to sugar moving tank 1, and transmission outlet d is connected to sugar feeding tank 2. Sugar moving tank 1 transmits sugar to transmission inlet c and then through pipeline 4 to transmission outlet d, and finally into sugar feeding tank 2.

[0062] The heating sleeve 32 is set at the transmission outlet d, so that the sugar is heated through the pipeline 4 before entering the sugar feeding tank 2, and then enters the sugar feeding tank 2 after heating, thus ensuring the accuracy of the temperature of the sugar in the sugar feeding tank 2.

[0063] The technical solution of this utility model embodiment, by setting the heating sleeve 32 at the transmission outlet d, allows the heated sugar to enter the sugar feeding tank 2 at the first time, further ensuring the temperature accuracy of the sugar in the sugar feeding tank 2, improving the heating effect, ensuring product quality, and reducing the risk of temperature drop.

[0064] Optionally, the heating sleeve includes a sleeve and at least one heating element; (the specific structure of the heating sleeve is not shown in the figure).

[0065] The heating element is housed in the receiving space of the sleeve; each heating element includes a heating receiver; the heating control terminal is electrically connected to each heating receiver.

[0066] The heating sleeve includes a sleeve and a heating element. The sleeve is used to fit over a pipeline and includes a receiving space. The heating element is placed in the receiving space of the sleeve, and the heat generated by the heating element can be transferred to the pipeline through the sleeve.

[0067] The sleeve may include at least one heating element, arranged in an array within the sleeve. Each heating element includes a heating receiver, and a heating control terminal is electrically connected to the heating receiver of the heating element. During operation, only one heating element may be active, while the others remain in reserve, ensuring that the heating sleeve does not require replacement due to heating element failure throughout its service life; alternatively, only some heating elements may be active, with the others in reserve, thus guaranteeing both heating efficiency and ensuring that the heating sleeve does not require replacement due to heating element failure throughout its service life.

[0068] In some embodiments, the heating element includes a ceramic heater, which ensures that the heating jacket has better insulation, corrosion resistance and high heat conversion efficiency during long-term use, thereby improving the reliability and stability of the heating system.

[0069] For example, the heating sleeve includes six heating elements. Each heating element includes a heating receiver. A heating control terminal is electrically connected to each of the six corresponding heating receivers. In operation, the heating control terminal inputs a heating start signal to only one heating receiver, thereby controlling one heating element to operate. The other five heating elements serve as backups. If a working heating element fails, the heating control terminal transmits a heating start signal to the heating receivers corresponding to the other heating elements, thus ensuring that the heating sleeve does not need to be replaced due to heating element failure throughout its service life.

[0070] The technical solution of this utility model embodiment involves setting a sleeve and at least one heating element within a heating sleeve. The heating element is housed within the sleeve, and its heating receiving end is electrically connected to a heating control end, allowing the heating control unit to control the operation of the heating element. Multiple heating elements can be provided as backups, ensuring that the heating sleeve does not need to be replaced due to heating element damage throughout its service life, thus guaranteeing the stability and reliability of the heating transmission system.

[0071] Optional, Figure 4 This is a schematic diagram of the internal circuit of a heating device according to an embodiment of the present utility model, combined with... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the heating control unit 31 includes a temperature controller 311 and a manual heating switch 312;

[0072] The thermostat 311 includes a heating control terminal a and a temperature adjustment terminal e; the manual heating switch 312 is set on the connection circuit between the heating control terminal a and the heating receiver terminal b.

[0073] The temperature controller 311 of the heating control unit 31 can be used to control the heating temperature of the heating sleeve 32; the manual heating switch 312 can start or stop the heating sleeve 32 according to the operator's operation.

[0074] Specifically, the heating control terminal a of the thermostat 311 is electrically connected to the heating receiving terminal b of the heating sleeve 32, transmitting a heating start signal to the heating receiving terminal b to control the heating sleeve 32 to start. The temperature control terminal e can control the temperature of the heating start signal output by the heating control terminal a through a temperature control signal input by the operator, thereby controlling the heating temperature of the heating sleeve 32. The manual heating switch 312 is set on the connection circuit between the heating control terminal a and the heating receiving terminal b, controlling the conduction and cutoff of the heating start signal, thereby controlling the working state and heating temperature of the heating sleeve 32.

[0075] For example, the temperature control terminal e may include a temperature control knob. In equipment debugging and maintenance mode, the transmission heating system starts in manual mode, and the operator can control the manual heating switch 312 and the temperature control knob. The heating control terminal a outputs a heating temperature signal according to the temperature indicated by the temperature control knob. The manual heating switch 312 connects the circuit between the heating control terminal a and the heating receiving terminal b. The heating temperature signal is input to the heating sleeve 32, and the heating sleeve 32 starts working and heats to the corresponding temperature according to the operator's instructions.

[0076] The technical solution of this utility model embodiment is to set a temperature controller 311 and a manual heating switch 312 in the heating control unit 31, electrically connect the heating control terminal a of the temperature controller 311 to the heating receiving terminal b, and set the manual heating switch 312 in the circuit between the heating control terminal a and the heating receiving terminal b, so that the operator can control the working state of the heating sleeve 32 according to the temperature control segment and the manual heating switch 312, and use a proportional integral controller to automatically adjust and maintain it within the fluctuation range of the process control value.

[0077] Optional, continue to refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the heating control unit 31 includes a temperature controller 311 and an automatic control unit 313;

[0078] Thermostat 311 includes a heating control terminal a and a control signal receiving terminal f;

[0079] The automatic control unit 313 includes a control signal transmitting end g and a feeding tank status receiving end h;

[0080] The control signal transmitting end g is electrically connected to the control signal receiving end f; the feeding tank status receiving end h is electrically connected to the sugar feeding tank 2 working status transmitting end i.

[0081] The heating control terminal a of the temperature controller 311 is electrically connected to the heating receiving terminal b of the heating sleeve 32. The control signal receiving terminal f is electrically connected to the control signal transmitting terminal g of the automatic control unit 313, and is used to receive the temperature control signal sent by the automatic control unit 313, thereby realizing automatic temperature control. The automatic control unit 313 also includes a feeding tank status receiving terminal h, which can receive the working status of the feeding tank in real time and output a temperature adjustment signal to the temperature controller 311 according to the working status of the feeding tank. The temperature controller 311 then transmits the heating temperature signal to the heating sleeve 32 to control the heating sleeve 32 to perform heating.

[0082] For example, when the sugar feeding tank 2 is in a pre-filled or working state, the sugar feeding tank 2 outputs a working state signal from the working state sending end i to the feeding tank state receiving end h. The automatic control unit 313 activates the automatic control mode and generates a temperature adjustment signal from the control signal sending end g to the control signal receiving end f of the temperature controller 311. The temperature controller 311 outputs a heating temperature signal from the heating control end a to the heating receiving end b. The heating sleeve 32 responds to the signal and performs constant temperature heating, ensuring automatic adjustment in a specific sugar feeding tank 2 mode.

[0083] It is understood that the technical solution of this utility model embodiment can adjust the working state of the heating sleeve 32 according to the working state of the sugar feeding tank 2, so that when the sugar feeding tank 2 is in the pre-filling or working state, the heating sleeve 32 can heat the liquid flowing through the heating sleeve 32 at a constant temperature, which improves the efficiency of the production line and reduces or eliminates potential product quality problems.

[0084] The technical solution of this utility model embodiment is to automatically control the heating sleeve 32 by setting a temperature controller 311 and an automatic control unit 313 in the heating control unit 31, and combining the working status of the sugar feeding tank 2 to ensure the synchronization of the heating sleeve 32 and the sugar feeding tank 2, so as to carry out timely and effective constant temperature heating, and use a proportional integral controller to automatically adjust so as to keep it fluctuating within the process control value range.

[0085] Optionally, the heating device may also include a power supply unit; (not shown in the figure)

[0086] The power supply unit includes a power supply terminal;

[0087] The heating control unit includes a first power supply receiver; the heating sleeve includes a second power supply receiver.

[0088] The power supply end is electrically connected to the first power supply receiving end and the second power supply receiving end, respectively.

[0089] The power supply unit provides power to the heating control unit and the heating sleeve. The power supply terminal of the power supply unit is electrically connected to the first power supply receiver and the second power supply receiver, respectively. The power output of the power supply unit is transmitted to the first power supply receiver and the second power supply receiver, thereby ensuring a continuous power supply to the heating control unit and the heating sleeve, and guaranteeing the normal operation of the heating system.

[0090] The technical solution of this utility model embodiment can also combine manual and automatic modes.
