Abstract
Description
Technical Field
[0001] This utility model relates to the field of reconstituted tobacco production, and more specifically, to a blending device for improving the uniformity of reconstituted tobacco pulp. Background Technology
[0002] Paper-based reconstituted tobacco refers to tobacco sheets produced using tobacco raw materials through a papermaking process. The paper-based reconstituted tobacco process includes key steps such as pulping, pulp preparation, and papermaking. Reducing the particle size of the tobacco raw materials helps to improve the coating rate of the paper-based reconstituted tobacco.
[0003] However, as the particle size of tobacco raw materials decreases, the surface tension of the tobacco raw material particles increases, making it difficult to mix the tobacco raw materials evenly during the pulping process.
[0004] Therefore, how to provide a blending device that can effectively improve the uniformity of slurry preparation and enhance the uniformity of reconstituted tobacco slurry has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0022] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.
[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.
[0024] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0025] like Figure 1 As shown, the blending device for improving the uniformity of reconstituted tobacco pulp provided by this utility model includes at least one set of pulp blending components, which includes a blending tank 1, a buffer tank 2, and a pulp outlet tank arranged in sequence.
[0026] The mixing tank 1 is equipped with a main pulp inlet 11, a first pulp outlet inlet 12, and a first buffer tank outlet 13. The pulp produced in the previous process (e.g., the pulping process) enters the mixing tank 1 through the main pulp inlet 11. The first pulp outlet inlet 12 receives pulp output from the pulp outlet tank 3. The first buffer tank outlet 13 discharges the pulp from the mixing tank 1 to the buffer tank 2.
[0027] The buffer tank 2 is equipped with a mixing tank inlet 21, a second outlet tank inlet 22, and an outlet tank outlet 23. The mixing tank inlet 21 is used to receive slurry output from the mixing tank 1. The second outlet tank inlet 22 is used to receive slurry output from the outlet tank 3. The outlet tank outlet 23 is used to output the slurry in the buffer tank 2 to the outlet tank 3.
[0028] The pulp discharge tank 3 is equipped with a buffer tank inlet 31, a mixing tank outlet 32, a second buffer tank outlet 33, and a main outlet 34. The buffer tank inlet 31 receives pulp from the buffer tank 2. The mixing tank outlet 32 discharges pulp from the discharge tank 3 to the mixing tank 1. The second buffer tank outlet 33 discharges pulp from the discharge tank 3 to the buffer tank 2. The main outlet 34 discharges pulp from the discharge tank 3 to the next process (e.g., papermaking).
[0029] The inlet 12 of the first discharge tank is in fluid communication with the outlet 32 of the mixing tank, so that the slurry in the discharge tank 3 can be output to the mixing tank 1.
[0030] The slurry outlet 13 of the first buffer tank is in fluid communication with the slurry inlet 21 of the mixing tank, so that the slurry in the mixing tank 1 can be output to the buffer tank 2.
[0031] The inlet 22 of the second discharge tank is in fluid communication with the outlet 33 of the second buffer tank, so that the slurry in the discharge tank 3 can be output to the buffer tank 2.
[0032] The slurry outlet 23 of the slurry outlet tank is in fluid communication with the slurry inlet 31 of the buffer tank, so that the slurry in the buffer tank 2 can be output to the slurry outlet tank 3.
[0033] All of the above fluid connections can be achieved through pipe connections.
[0034] The blending device for improving the uniformity of reconstituted tobacco pulp of this utility model has two different output modes: forward output (meaning that the pulp is output from the first tank to the last tank along the sequentially arranged blending tank 1, buffer tank 2 and pulp outlet tank 3) and reverse output (meaning that the pulp is output from the last tank to the first tank along the sequentially arranged blending tank 1, buffer tank 2 and pulp outlet tank 3). This ensures that the pulp in each tank is fully mixed, effectively improving the uniformity of the pulp output from the main pulp outlet 34 to the next process.
[0035] The blending device for improving the uniformity of reconstituted tobacco pulp provided by this utility model reverses the flow of pulp from the discharge tank 3 to the blending tank 1 and the buffer tank 2, so that the pulp in the blending device is always in a dynamic mixing state, which is beneficial to effectively improve the blending uniformity of the output pulp.
[0036] In one embodiment of the blending device for improving the uniformity of reconstituted tobacco pulp of this utility model, in order to improve the uniformity of the pulp, the main pulp inlet 11 is located above the pulp inlet 12 of the first pulp outlet tank and the pulp outlet 13 of the first buffer tank, and the pulp outlet 13 of the first buffer tank is located above the pulp inlet 12 of the first pulp outlet tank.
[0037] In one embodiment of the blending device for improving the uniformity of reconstituted tobacco pulp of this utility model, in order to improve the uniformity of the pulp, the blending tank inlet 21 and the second outlet tank inlet 22 are located above the outlet tank outlet 23, and the blending tank inlet 21 is located above the second outlet tank inlet 22.
[0038] In one embodiment of the blending device for improving the uniformity of reconstituted tobacco pulp of this utility model, in order to improve the uniformity of the pulp, the inlet 31 of the buffer tank is located above the outlet 32 of the blending tank, the outlet 33 of the second buffer tank, and the main outlet 34, and the outlet 32 of the blending tank and the outlet 33 of the second buffer tank are located above the main outlet 34.
[0039] Furthermore, in order to more effectively improve the uniformity of the slurry, the slurry outlet 33 of the second buffer tank is located above the slurry outlet 32 of the mixing tank.
[0040] In one embodiment of the blending device for improving the uniformity of reconstituted tobacco pulp of this utility model, the volume of the pulp outlet tank 3 is smaller than the volume of the blending tank 1 and the buffer tank 2, so that the pulp in the pulp outlet tank 3 can be mixed more efficiently.
[0041] In one embodiment of the blending device for improving the uniformity of reconstituted tobacco pulp according to this utility model, the blending tank 1, the buffer tank 2, and the pulp discharge tank 3 are all equipped with a stirring mechanism located at the bottom of the tank. The number of stirring mechanisms can be flexibly set according to actual needs. For example, each tank bottom is equipped with two stirring mechanisms.
[0042] In one embodiment of the blending device for improving the uniformity of reconstituted tobacco pulp according to this utility model, the device includes multiple sets of pulp blending components, which are arranged in parallel. Multiple sets of pulp blending components output pulp to the next process simultaneously, further ensuring the uniformity of the pulp received in the next process.
[0043] Furthermore, in order to control costs while ensuring uniformity, the blending device for improving the uniformity of reconstituted tobacco pulp includes three sets of pulp blending components.
[0044] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
