Description

Technical Field

[0001] The present invention relates to the technical field of tobacco liquid, in particular to a self-circulation stirring system, application and method for liquid in a small-diameter storage tank. Background Art

[0002] The statements in this part only provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] The flavor and fragrance liquid for cigarette making is stored in a storage tank with a small opening. It is transported to the manufacturing factory in units of a set mass, such as 200 Kg / barrel. During the batching process, the liquid shows a layering phenomenon, with the concentration of the lower-layer liquid being higher than that of the upper-layer liquid, and the viscosity of the low-temperature liquid being higher than that of the high-temperature liquid. When extracting the flavor and fragrance liquid for batching, it is necessary to stir in advance to ensure that the concentration and viscosity of the liquid are uniform. The existing stirring methods take a long time and require shutting down the machine to stir the flavor and fragrance liquid, which affects the normal operation of the current equipment and increases the non-value-added time for flavor and fragrance batching. According to statistics, when the ambient temperature (in winter) is <10°C, the non-value-added time for flavor and fragrance batching increases by more than 50% compared to when the ambient temperature (in summer) is ≥25°C.

[0004] In addition, according to the requirements of the cigarette making production process, it is necessary to minimize the pollution of the liquid and reduce the loss of the liquid during the batching process. For some stirring methods, since external equipment is inserted into the storage tank during stirring and the stirring is carried out by driving a stirring rod through a stirring motor, some stirring rods are equipped with stirring blades and cannot be inserted into the small opening (less than or equal to 6 cm) of the storage tank. Some manufacturers will modify the size of the storage tank opening, which will also pollute the liquid during the modification process. If only the stirring rod without the stirring blade is used, due to the limited contact area between the stirring rod and the liquid and the certain viscosity of the liquid, the stirring time is long, and sometimes even a long stirring time may not guarantee the stirring quality. In addition, during the stirring process, the opening of the storage tank is not sealed, and external pollutants are likely to enter the storage tank, causing pollution of the liquid.

[0005] Some material leveling methods have a certain problem of wasting the liquid. Summary of the Invention

[0006] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a self-circulation stirring system for liquid in a small-diameter storage tank, which can achieve rapid leveling of tobacco liquid and minimize pollution and liquid loss to the tobacco liquid.

[0007] To achieve the above purpose, the present invention is realized through the following technical solutions:

[0008] In a first aspect, the present invention provides a self-circulating stirring system for liquid materials in a small-diameter storage tank, which includes a material suction pipe, a material leveling pipe, and a sealing support assembly. One end of the material suction pipe and the material leveling pipe are respectively connected to a suction mechanism, and the suction mechanism is supported. The sealing support assembly includes a support member and a sealing member. The support member is detachably fixed to the upper side of the opening of the liquid material storage tank. The support member is connected to the sealing member, and the sealing member can be embedded into the opening of the liquid material storage tank. The support member and the sealing member are both provided with through holes. The material suction pipe and the material leveling pipe respectively pass through the through holes of the support member and the sealing member in sequence and then enter the liquid material storage tank to suck and level the liquid materials.

[0009] For a self-circulating stirring system for liquid materials in a small-diameter storage tank as described above, to quickly fix the sealing support assembly at the opening of the liquid material storage tank and also achieve quick separation, the support member is detachably fixed to the peripheral side of the opening of the liquid material storage tank by a magnet.

[0010] For a self-circulating stirring system for liquid materials in a small-diameter storage tank as described above, the magnet is an annular magnet. A first fastener passes through the hollow part of the magnet and is connected to the support member, and multiple magnets are provided.

[0011] For a self-circulating stirring system for liquid materials in a small-diameter storage tank as described above, the support member is a support plate. The through hole provided in the support member is a first through hole. There are two first through holes in the middle of the support member. The width of the support plate is greater than the inner diameter of the opening of the liquid material storage tank, and the magnets are arranged at the four corners of the support plate.

[0012] For a self-circulating stirring system for liquid materials in a small-diameter storage tank as described above, the sealing member is a rubber block. The outer diameter of the sealing member is greater than or equal to or less than the inner diameter of the opening of the liquid material storage tank. The through hole of the sealing member is a second through hole, and there are two second through holes. A second fastener connects the sealing member and the support member.

[0013] For a self-circulating stirring system for liquid materials in a small-diameter storage tank as described above, the material suction pipe includes a first hard pipe and a first hose. The first hard pipe and the first hose are connected. The first hose is connected to the inlet of the suction mechanism. The first hard pipe is inserted into the through holes of the support member and the sealing member, and a suction port is provided at one end of the first hard pipe away from the first hose.

[0014] For a self-circulating stirring system for liquid materials in a small-diameter storage tank as described above, the material leveling pipe includes a second hard pipe and a second hose. The second hard pipe and the second hose are connected. The second hose is connected to the inlet of the suction mechanism. The second hard pipe is inserted into the through holes of the support member and the sealing member, and discharge holes are provided on the side wall and the end of one section of the second hard pipe away from the second hose.

[0015] A self - circulating stirring system for liquid in a small - diameter storage tank as described above, wherein the suction mechanism is supported by a bracket. The bracket has a set height, and movable wheels are provided at the bottom of the bracket to facilitate the movement of the entire system;

[0016] The length of the material suction pipe entering the liquid storage tank is greater than the length of the material leveling pipe entering the liquid storage tank, so that the material suction pipe can enter the bottom layer of the liquid to suck the liquid with a higher concentration.

[0017] In a second aspect, the present invention provides an application of a self - circulating stirring system for liquid in a small - diameter storage tank, which is applied to leveling the tobacco liquid in a tobacco liquid storage tank.

[0018] In a third aspect, the present invention further provides a method for stirring liquid in a small - diameter storage tank, using the self - circulating stirring system for liquid in a small - diameter storage tank as described above, including the following steps:

[0019] Connect the support member and the seal member, and align the through - holes of the two when connecting;

[0020] The material suction pipe and the material leveling pipe respectively pass through the through - holes of the support member and the seal member in sequence;

[0021] One ends of the material suction pipe and the material leveling pipe are respectively connected to the suction mechanism. Embed the seal member into the opening of the liquid storage tank, and fix the support member on the periphery of the opening of the liquid storage tank;

[0022] Support the suction mechanism. When the suction mechanism works, the liquid in the liquid storage tank is sucked through the material suction pipe and enters the suction mechanism. The liquid enters the material leveling pipe through the outlet of the suction mechanism, and uses the flow impact force of the liquid itself to level the stratified liquid in the liquid storage tank to achieve uniform stirring;

[0023] After the stirring is completed, disconnect the support member from the liquid storage tank, pull out the material suction pipe and the material leveling pipe from the opening of the liquid storage tank. The material leveling pipe enters the opening of the liquid storage tank again, and the material suction pipe sucks air to send the liquid in the material suction pipe, the material leveling pipe and the suction mechanism into the liquid storage tank.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1) The stirring system provided by the present invention utilizes the small - diameter opening of the storage tank without opening another larger opening in the storage tank, thus avoiding the pollution problem of the liquid caused by modifying the storage tank. The whole does not stir the liquid through large blades. The support member is detachably fixed on the upper side of the opening of the liquid storage tank, and the seal member is embedded into the opening of the liquid storage tank. The seal member plays a role in sealing the opening of the liquid storage tank during the leveling process to prevent foreign substances from entering the liquid storage tank during the leveling process. Overall, it relies on the material suction pipe to absorb the liquid and then discharge it through the material leveling pipe, and uses the flow impact force of the liquid itself to level the stratified liquid, ensuring the leveling speed while effectively avoiding the pollution problem of the liquid.

[0026] 2) In the present invention, the structure of the sealing and supporting assembly is reasonably arranged. The seal is connected to the support, and the seal can be quickly inserted into the opening of the tobacco liquid storage tank. The support is exposed on the upper side of the opening of the tobacco liquid storage tank, and the support is detachably connected to the tobacco liquid storage tank, ensuring the stability of the suction pipe and the material leveling pipe during operation.

[0027] 3) In the present invention, the support is detachably fixed to the periphery of the opening of the liquid storage tank by a magnet. The setting of the magnet ensures that the support is stably fixed on the upper side of the opening of the tobacco liquid storage tank, and the magnet also facilitates the quick separation from the liquid storage tank. After the material leveling is completed, the suction pipe, the material leveling pipe, and the sealing and supporting assembly can be quickly separated from the liquid storage tank.

[0028] 4) In the present invention, the length of the suction pipe is greater than that of the material leveling pipe, so that the suction pipe can enter the bottom layer of the liquid to suck the liquid with a higher concentration. The structures of the suction pipe and the material leveling pipe are reasonably arranged, which not only facilitates the connection with the suction mechanism, ensures the suction of the liquid or the discharge of the liquid, but also the setting of the material leveling pipe, in cooperation with the suction mechanism, makes the liquid discharged from the material leveling pipe have a certain speed, which can quickly impact the liquid, facilitate the stirring of the liquid, and is conducive to quickly achieving uniform stirring.

[0029] 5) In the present invention, when the suction mechanism withdraws the suction pipe and the material leveling pipe, the suction pipe can suck air and fill the liquid in the entire pipeline into the liquid storage tank, without causing waste of the liquid. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] It should be noted that the following detailed description is illustrative and is intended to provide further description of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0042] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the present invention otherwise clearly indicates, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations;

[0043] As introduced in the background art, when the layering problem occurs in the tobacco liquor in the prior art, stirring is required to homogenize the liquor. However, the existing homogenizing system needs to modify the opening, or the stirring time is relatively long, resulting in low efficiency. Moreover, there is also a problem of contaminating the liquor during the stirring process. To solve the above technical problems, the present invention proposes a self-circulating stirring system for the liquor in a small-diameter storage tank.

[0044] Embodiment 1

[0045] In a typical embodiment of the present invention, referring to Figure 1 As shown, a self-circulating stirring system for the liquor in a small-diameter storage tank includes a material suction pipe 3, a homogenizing pipe 4, and a sealing and supporting assembly. One ends of the material suction pipe 3 and the homogenizing pipe 4 are respectively connected to a suction mechanism 2. The suction mechanism 2 is supported. The sealing and supporting assembly includes a support member 6 and a sealing member 8. The support member 6 is detachably fixed on the upper side of the opening of the liquor storage tank to ensure the stability of the material suction pipe 3 and the homogenizing pipe 4 during the working process. The support member 6 is connected to the sealing member 8. The sealing member 8 can be embedded into the opening of the liquor storage tank to effectively isolate the outside from the liquor inside the liquor storage tank. Through holes are provided in both the support member 6 and the sealing member 8. The material suction pipe 3 and the homogenizing pipe 4 respectively pass through the through holes of the support member 6 and the sealing member 8 in sequence and then enter the liquor storage tank to suck and homogenize the liquor.

[0046] To quickly fix the sealing and supporting assembly at the opening of the liquor storage tank and also achieve quick separation, the support member 6 is detachably fixed on the periphery of the opening of the liquor storage tank by a magnet 16; the space on the periphery of the opening of the liquor storage tank is reasonably utilized to arrange the magnet 16 to ensure that the support member 6 can be quickly installed at the opening of the liquor storage tank and can also achieve quick separation. Moreover, the support member 6 is connected to the sealing member 8. The sealing member 8 can be inserted into the opening of the liquor storage tank. The support member 6 is placed on the upper side of the opening of the liquor storage tank to effectively seal the opening of the liquor storage tank during the homogenizing process and prevent impurities from entering the inside of the liquor storage tank.

[0047] Referring to Figure 2 and Figure 3As shown, the support member 6 is a support plate. The material of the support plate is a stainless steel plate. The support plate is a rectangular plate. The width of the support plate is greater than the inner diameter of the opening of the liquid storage tank. Magnets 16 are provided at the four corners of the support plate. The magnets 16 are annular magnets. The first fastener, such as the first screw 11, passes through the hollow part of the magnet 16 and the support member and is then fastened by the first nut 14. There are multiple magnets 16. The head of the first screw 11 contacts the top of the liquid storage tank. In some examples, a step is provided on the screw rod of the first screw 11 to limit the position of the magnet 16. At this time, a spacing distance is set between the magnet and the head of the first screw 11. In this way, the first screw 11 is equivalent to a support leg, so that the support member 6 can be supported on the upper side of the opening of the liquid storage tank. The magnets 16 are placed on the periphery of the opening of the liquid storage tank. Since the liquid storage tank is an iron tank, the magnets 16 make the support member 6 stably arranged above the opening of the liquid storage tank, which is beneficial to keeping the material equalizing pipe and the material suction pipe stable during the operation of the system.

[0048] In some other examples, referring to Figure 5 and Figure 6 as shown, a central hole 17 is provided inside the magnet 16. The central hole 17 is a stepped hole. The shape of the central hole 17 is the same as the shape of the head of the first screw 11, so that the head of the first screw 11 is stuck at the central hole 17 of the magnet to ensure that the magnet 16 is adsorbed on the top of the liquid storage tank.

[0049] It should be noted that the through hole provided on the support member 6 is the first through hole 7. There are two first through holes 7 in the middle of the support member 6, respectively for the material suction pipe and the material equalizing pipe to pass through. A first connecting hole 18 is provided between the two first through holes 7. There are two first connecting holes 18, and the two first connecting holes are symmetrically arranged about the center point of the support member.

[0050] Among them, the sealing member 8 is a rubber block. The rubber block has a set thickness. The thickness of the sealing member 8 is greater than the thickness of the support member. The sealing member 8 is placed below the support member 6. The setting of the support member 6 not only facilitates the embedding of the sealing member into the opening of the liquid storage tank, but also facilitates the separation of the sealing member 8 from the opening of the liquid storage tank. Moreover, the support member 6 is placed above the sealing member 8 to further prevent impurities from entering the opening of the liquid storage tank;

[0051] The outer diameter of the sealing member 8 is greater than or equal to or less than the inner diameter of the opening of the liquid storage tank. Since the sealing member 8 is made of rubber material, it is beneficial to insert the sealing member 8 into the opening of the liquid storage tank. Referring to Figure 4 as shown, the through hole of the sealing member 8 is the second through hole 9. There are two second through holes 9. The inner diameter of the second through hole 9 is the same as the inner diameter of the first through hole, and both are for the material suction pipe 3 and the material equalizing pipe 4 to pass through. The second fastener, such as the second screw 12, connects the sealing member and the support member. A second connecting hole 10 is provided between the two second through holes. The second screw 12 passes through the first connecting hole 18 and the second connecting hole 10 of the sealing member, and then a gasket 13 is provided and locked by the second nut 15.

[0052] In this embodiment, the suction mechanism 2 is a pneumatic diaphragm pump, which is the power device of the self-circulating stirring system. It uses compressed air as the power and is preferably selected to be large rather than small to be able to pump thick liquid materials.

[0053] The suction mechanism is supported by the bracket 1. The bracket 1 has a set height. A workbench is provided at the top of the bracket to support the suction mechanism. The length of the workbench is greater than the length of the suction mechanism, so that there is space on the workbench surface to place the material suction pipe and the material leveling pipe before and after work. In some examples, the base of the suction mechanism is fixed to the workbench at the top of the bracket to ensure the stability of the suction mechanism. Movable wheels are provided at the bottom of the bracket 1 to facilitate the movement of the entire system. Since there are many liquid material storage tanks, the bracket is moved according to requirements so that the entire system is moved to one side of the corresponding liquid material storage tank.

[0054] In some examples, recesses are provided at the top of the workbench. The recesses can be arranged along the width direction of the workbench, or the recesses are inclined relative to the width direction of the workbench. There can be two recesses, and the material suction pipe and the material leveling pipe before or after work can be placed in the corresponding recesses.

[0055] Specifically, the material suction pipe 3 includes a first hard pipe 19 and a first hose. The first hard pipe 19 and the first hose are connected. The first hose is connected to the inlet of the suction mechanism. The first hard pipe is inserted into the through holes of the support member and the seal. Refer to Figure 7 As shown, a suction port is provided at one end of the first hard pipe 19 away from the first hose. The first hose is a steel wire plastic pipe. After the first hose is connected to the suction mechanism, it is fixed by a hose clamp. The first hose is connected to the first hard pipe 19 through a pipe joint 20. The pipe joint is inserted into the first hard pipe 19 and then welded. The material of the first hard pipe can be a stainless steel pipe, and the outer diameter of the pipe joint 20 is adapted to the inner diameter of the first hard pipe.

[0056] The material leveling pipe includes a second hard pipe 21 and a second hose. The second hard pipe and the second hose are connected. The second hose is connected to the inlet of the suction mechanism. The second hard pipe 21 is inserted into the through holes of the support member and the seal. The second hard pipe is also connected to the second hose through a pipe joint. The second hose is a steel wire plastic pipe. After the second hose is connected to the suction mechanism, it is fixed by a hose clamp. Refer to Figure 8 As shown, the second hard pipe 21 is also a stainless steel pipe. Five pairs of discharge holes 22 are provided on both side walls of one end of the second hard pipe 21 away from the second hose, and discharge holes 22 are also provided at one end of the second hard pipe 21 away from the second hose. In this way, the discharge holes on the side wall and the bottom of the second hard pipe can facilitate the discharge of the liquid material and facilitate the use of the flow impact force of the liquid material to evenly layer the liquid material.

[0057] It should be noted that the length of the second rigid tube 21 is greater than that of the first rigid tube 19, so that the second rigid tube can enter the bottom layer of the liquid material to suck the liquid material with a higher concentration.

[0058] The self-circulating stirring system provided in this embodiment can not only be used for leveling the tobacco liquid material in the tobacco liquid storage tank, but also for leveling the liquid material in other industries. It makes overall use of the small-diameter opening at the top of the liquid storage tank, without the need for large stirring blades, and is detachably fixed to the upper side of the opening of the liquid storage tank through the support member. The sealing member is embedded in the opening of the liquid storage tank, and the sealing member plays a role in sealing the opening of the liquid storage tank during the leveling process, avoiding the entry of external substances into the liquid storage tank during the leveling process. Overall, it relies on the suction pipe to absorb the liquid material and then discharge it through the leveling pipe, and uses the flow impact force of the liquid material itself to evenly stratify the liquid material, ensuring the leveling speed, avoiding delaying the production progress due to a long leveling time, and effectively avoiding the problem of liquid material pollution.

[0059] Embodiment 2

[0060] This embodiment discloses a method for stirring liquid material in a small-diameter storage tank. For example, to achieve leveling of the tobacco liquid material in the tobacco liquid storage tank, a self-circulating stirring system for liquid material in a small-diameter storage tank described in Embodiment 1 is adopted, including the following content:

[0061] Connect the support member 6 and the sealing member 8, and align the first through hole 7 and the second through hole 9 of the two when connecting.

[0062] The suction pipe 3 and the leveling pipe 4 respectively pass through the first through hole of the support member and the second through hole of the sealing member in sequence.

[0063] One ends of the suction pipe 3 and the leveling pipe 4 are respectively connected to the suction mechanism 2. Embed the sealing member 8 into the opening of the liquid storage tank, and fix the support member to the periphery of the opening of the liquid storage tank through the magnet on the periphery of the support member.

[0064] The bracket supports the suction mechanism 2. When the suction mechanism 2 works, the liquid material in the liquid storage tank is sucked through the suction pipe 3 and enters the suction mechanism. The liquid material enters the leveling pipe 4 through the outlet of the suction mechanism. The flow impact force of the liquid material itself is used to level the stratified liquid material in the liquid storage tank. Because the suction mechanism 2 has a certain power, the liquid material has a certain speed when discharging, which can impact the liquid material. Moreover, discharge holes 22 are provided on the side wall and bottom of the leveling pipe 4, which is beneficial to quickly achieve uniform stirring. In this way, compared with the method of only stirring through the stirring rod alone, the leveling speed is improved.

[0065] After the stirring is completed, disconnect the support member from the liquid storage tank, draw out the suction pipe and the leveling pipe from the opening of the liquid storage tank. The leveling pipe enters the opening of the liquid storage tank again, and the suction pipe sucks air to send the liquid material in the suction pipe, the leveling pipe and the suction mechanism into the liquid storage tank, avoiding waste of the liquid material.

[0066] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
