Description

Technical Field

[0001] This invention relates to the field of liquor bottling machine technology, specifically to a liquor vapor recovery device for liquor bottling machines. Background Technology

[0002] Alcohol in baijiu is a flammable substance with a low flash point. Flash point refers to the lowest temperature at which a liquid begins to evaporate flammable gas and form a flammable mixture with air under specific conditions. It is highly volatile. The higher the concentration of baijiu, the lower its flash point, and therefore the easier it is to ignite. The flash point of alcohol varies with its concentration, making it less safe. Its fire hazard classification is Class A.

[0003] In social production, manufacturers prevent the combustion and explosion of alcohol vapors by setting up explosion-proof workshops and using explosion-proof equipment to isolate ignition sources. However, in a confined space, it is not only the ignition source that can cause an explosion; the concentration of alcohol in the environment is also an important indicator. When the alcohol concentration is at the explosive limit, it will explode when it encounters an ignition source. A large amount of alcohol vapor is generated during the recycling and bottling process. The increased alcohol concentration in the air increases the possibility of alcohol vapor combustion and explosion, which is detrimental to production safety. To address this, we have designed an alcohol vapor recovery device for a baijiu bottling machine, aiming to recover the large amount of alcohol vapor generated during the bottling process, reduce the possibility of alcohol vapor combustion and explosion from the concentration level, and improve production safety. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the large amount of alcohol vapor generated during the production of baijiu (Chinese liquor) recycling and bottling can easily cause combustion and explosion. This invention provides an alcohol vapor recovery device for baijiu bottling machines.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] The liquor bottling machine includes a liquor vapor recovery device, comprising a fixed frame. A slewing bearing is rotatably mounted on the top of the fixed frame. A lower rotating platform is movably connected to the top of the slewing bearing. An internal gear in the slewing bearing drives the free rotation of the lower rotating platform. Providing the slewing bearing with a driving force, such as a motor driving the gears, allows the lower rotating platform to rotate freely and simultaneously rotate the entire upper part. A turbine lifting device is installed on top of the lower rotating platform. A motor drives a turbine to rotate a worm gear, adjusting the relative distance between the upper and lower rotating platforms to adjust the bottling height to accommodate different bottle types. An upper rotating platform is movably mounted on top of the turbine lifting device. A liquor tank is bolted to the top of the upper rotating platform. Several channels are opened on the lower side of the liquor tank as liquor input channels. The channels below the liquor tank are connected to... The central distributor allows the liquor to be directly delivered from external pipes to the liquor tank. A thin tube is installed directly below the liquor tank, and each of these tubes is connected to a filling valve via a flow meter, forming a filling channel: liquor—central distributor—liquid tank—filling valve—bottle. The filling valve has an internal reflux chamber, which is bolted to the turntable of the upper rotating platform. The reflux chamber has an external number of inlet channels equal to the number of filling valves, and an internal number of outlet channels equal to the number of interfaces on the central distributor. The liquor vapor absorbed by the filling valves collects in the reflux chamber. When a negative pressure suction device, such as a fan, is provided externally to the main unit, a liquor vapor recovery channel is formed inside the main unit: liquor vapor—filling valve—reflux chamber—central distributor—external negative pressure suction—processing and emission.

[0007] Furthermore, the central distributor, as the conveying carrier of the rotating equipment, is responsible for the input of liquid and the output of vapor. The two flow channels work independently. The central distributor includes a connecting flange, an upper bearing seat, a liquid ring cavity, a vapor ring cavity, a lower bearing seat, a bearing cover, a shaft core, a rotary seal, and a bearing area. The connecting flange is fixedly connected to the upper rotating platform by bolts. The portion of the return ring cavity and the portion of the shaft core are in communication. The bottom end of the shaft core is connected to the portion of the wine tank through a channel. After the liquid enters from the bottom shaft core, it can enter the wine tank for filling through the upper outlet. The shaft core is connected to the external pipeline to complete the medium transfer and transportation. An outlet is provided on the outer side of the shaft core. After the vapor collected from the return ring cavity enters the shaft core, it is transported along the outer channel of the shaft core to the side outlet of the distributor.

[0008] Furthermore, the connecting flange, the upper bearing seat, the liquid ring cavity, the vapor ring cavity, the lower bearing seat, and the bearing cover are all located on the left side of the shaft core and are fastened together in series by bolts. The liquid ring cavity is connected to the central channel of the shaft core, and the vapor ring cavity is connected to the outer side of the shaft core.

[0009] Furthermore, the rotary seal and the bearing area are both located on the right side of the shaft core, and the bearing area is located above the shaft core. The connecting flange and the front side of the upper bearing seat are movably connected to the rear side of the bearing area. The rotary seal is provided in multiple sets and is respectively connected to the inner end of the liquid ring cavity, the gas ring cavity, and the lower bearing seat.

[0010] Furthermore, the filling valve is fixedly connected to the turntable of the upper rotating platform. The filling valve includes a control end, a diaphragm, an upper valve body, a lower valve body, a valve core, a sealing ring, and a valve nozzle. The upper valve body has a wine inlet channel inside to receive the wine flowing out of the wine tank. The wine inlet channel of the upper valve body is connected to the wine tank. The bottom of the lower valve body has a trumpet-shaped wine vapor absorption port, and the top of the lower valve body has an outlet channel. The absorbed wine vapor is discharged from the outlet channel at the top of the lower valve body.

[0011] Furthermore, the diaphragm is disposed in the middle of the inside of the control end, and the sidewall of the diaphragm is laterally located inside the control end. The tops of the upper valve body, the lower valve body, the valve core, the sealing ring, and the valve nozzle are all located below the diaphragm. The bottom of the lower valve body is threaded together with the valve nozzle. The valve core is located in the middle of the entire filling valve. The sealing ring and the upper valve body are movably connected.

[0012] Furthermore, the inside of the valve nozzle is equipped with several layers of filter screens to eliminate air bubbles generated during filling. A gap is provided between the upper valve body and the sealing ring. The valve nozzle is located below the gap between the upper valve body and the sealing ring. The wine flows out through the gap and into the wine bottle below for filling. After filling is completed, the valve core returns to its original position.

[0013] Furthermore, both the upper valve body and the lower valve body are located outside the valve core, and the sealing ring is disposed above the valve core.

[0014] Compared with the prior art, the present invention provides a liquor vapor recovery device for a liquor bottling machine, which has the following beneficial effects:

[0015] 1. The alcohol vapor recovery device of this liquor bottling machine recovers a large amount of alcohol vapor generated during the bottling process. This alcohol vapor recovery device can effectively reduce the leakage of alcohol vapor during the bottling process, reduce the concentration of alcohol vapor in the space, reduce the possibility of alcohol vapor combustion from the concentration level, and improve production safety.

[0016] 2. The alcohol vapor recovery device of this liquor filling machine, through the structural design of the upper and lower flow channels of the filling valve body, uses negative pressure to collect alcohol vapor from the valve port of the filling valve. After passing through the annular cavity buffer, it is uniformly led out by the central distributor. The filling channel and the alcohol vapor recovery channel are structurally independent and can be used for filling and alcohol vapor recovery respectively. They can also be connected in series for other production operations such as venting and cleaning. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1-8 As shown, the liquor bottling machine's vapor recovery device includes a fixed frame 1. A rotary bearing 2 is rotatably mounted on the top of the fixed frame 1. A lower rotating platform 3 is movably connected to the top of the rotary bearing 2. The internal gears of the rotary bearing 2 drive the free rotation of the lower rotating platform 3, providing a driving force such as a motor driving the gears. This allows the lower rotating platform 3 to rotate freely and drive the entire upper part to rotate synchronously. A turbine lifting device 4 is installed on the top of the lower rotating platform 3. A motor drives the turbine to rotate the worm gear, adjusting the relative distance between the upper rotating platform 5 and the lower rotating platform 3 to adjust the bottling height to accommodate different bottle types. An upper rotating platform 5 is movably mounted on the top of the turbine lifting device 4. A liquor tank 6 is bolted to the top of the upper rotating platform 5. Several channels are opened on the lower side of the liquor tank 6 as liquor input channels. The channels below the liquor tank 6 are connected to... The central distributor 7 allows the liquor to be directly transported from the external pipe to the liquor tank 6. A thin tube is installed directly below the liquor tank 6, and each thin tube below the liquor tank 6 is connected to a filling valve 8 via a flow meter, forming a filling channel of liquor—central distributor 7—liquid tank 6—filling valve 8—liquid bottle. The filling valve 8 is internally connected to a return ring cavity 9, which is fixed to the turntable of the upper rotating platform 5 by bolts. The return ring cavity 9 has an external number of liquor vapor inlet channels equal to the number of filling valves 8, and an internal number of liquor vapor outlet channels 10 equal to the number of interfaces of the central distributor 7. The liquor vapor absorbed by the filling valves is collected in the return ring cavity 9. When a negative pressure suction power device, such as a fan, is provided outside the main unit, a liquor vapor—filling valve 8—return ring cavity 9—central distributor 7—external negative pressure suction—processed and discharged liquor vapor recovery channel is formed inside the main unit.

[0028] like Figure 1 and Figure 7As shown, in some embodiments, the central distributor 7 serves as the conveying carrier of the rotating device, responsible for the input of liquid and the output of vapor. The two flow channels operate independently. The central distributor 7 includes a connecting flange 701, an upper bearing seat 702, a liquid annular cavity 703, a vapor annular cavity 704, a lower bearing seat 705, a bearing cover 706, a shaft core 707, a rotary seal 708, and a bearing area 709. The connecting flange 701 is fixedly connected to the upper rotating table 5 by bolts. The portion of the return annular cavity 9 and the portion of the shaft core 707 communicate with each other. The bottom end of the shaft core 707 is connected to the portion of the wine tank 6 through a channel. The liquid enters from the bottom shaft core and then flows through... The contents can be fed into the wine tank 6 through the upper outlet for filling. The shaft core 707 is connected to the external pipeline to complete the transfer and transportation of the medium. The outer side of the shaft core 707 is provided with an outlet. After the wine vapor collected from the return ring cavity enters the shaft core 707, it is transported to the side outlet of the distributor along the outer channel of the shaft core. The connecting flange 701, the upper bearing seat 702, the wine liquid ring cavity 703, the wine vapor ring cavity 704, the lower bearing seat 705 and the bearing cover 706 are all located on the left side of the shaft core 707 and are fastened together by bolts. The wine liquid ring cavity 703 is connected to the central channel of the shaft core 707, and the wine vapor ring cavity 704 is connected to the outer side of the shaft core 707.

[0029] like Figures 1-8 As shown, in some embodiments, the rotary seal 708 and the bearing area 709 are both located on the right side of the shaft core 707, and the bearing area 709 is located above the shaft core 707. The front side of the connecting flange 701 and the upper bearing seat 702 are movably connected to the rear side of the bearing area 709. The rotary seal 708 is provided in multiple sets and is respectively connected to the inner end of the liquid ring cavity 703, the gas ring cavity 704, and the lower bearing seat 705.

[0030] like Figures 1-4As shown, in some embodiments, the filling valve 8 is fixedly connected to the turntable of the upper rotating platform 5. The filling valve 8 includes a control end 801, a diaphragm 802, an upper valve body 803, a lower valve body 804, a valve core 805, a sealing ring 806, and a valve nozzle 807. The upper valve body 803 has a wine inlet 11 channel inside to receive the wine flowing out of the wine tank. The wine inlet 11 channel of the upper valve body 803 is connected to the wine tank 6. The bottom of the lower valve body 804 has a trumpet-shaped wine vapor absorption port, and the top of the lower valve body 804 has an outlet channel. The absorbed wine vapor is discharged from the outlet channel at the top of the lower valve body 804. The diaphragm 802 is disposed in the middle of the control end 801, and the sidewall of the diaphragm 802 is laterally located inside the control end 801. The upper valve body 803, lower valve body 804, and valve core 805 are also present. The tops of the sealing ring 806 and the valve nozzle 807 are both located below the diaphragm 802. The bottom of the lower valve body 804 is threaded together with the valve nozzle 807. The valve core 805 is located in the middle of the entire filling valve 8. The sealing ring 806 and the upper valve body 803 are movably connected. Several layers of filter screens are installed inside the valve nozzle 807 to eliminate air bubbles generated during filling. A gap is provided between the upper valve body 803 and the sealing ring 806. The valve nozzle 807 is located below the gap between the upper valve body 803 and the sealing ring 806. The wine flows out through the gap and into the wine bottle below through the nozzle 807 for filling. After filling, the valve core 805 returns to its original position. The upper valve body 803 and the lower valve body 804 are both located outside the valve core 805. The sealing ring 806 is located above the valve core 805.

[0031] The liquor enters the filling machine's vat 6 from below the central distributor 7, ready for filling. The valve core 805 moves down, opening the filling valve 8, and the liquor flows into the bottle along the valve core 805. During this process, the liquor vapor overflows outward from the filling valve 8. The recovery device is activated simultaneously, powered by an external negative pressure suction system. The overflowing liquor vapor is absorbed by the trumpet-shaped liquor vapor absorption port of the lower valve body 804. After being collected in the annular cavity 9, the liquor vapor is led out through the liquor vapor recovery channel of the central distributor 7. The liquor vapor is treated and vented outside the filling workshop, completing the liquor vapor recovery operation, which can effectively reduce the liquor vapor concentration during filling production. In addition, the liquor vapor recovery device can operate independently. After filling stops, if the liquor vapor concentration in the filling workshop is detected to exceed the safe value, the device can be automatically activated to recover the liquor vapor.

[0032] Furthermore, the filling channel and the recovery channel can be connected. By adding an upper cap below the filling valve 8, the liquid inlet 11 and the gas outlet 10 of the filling valve 8 are connected, making the entire filling machine equivalent to a large pipeline. This allows for other production operations. For example, when gas is introduced into the filling machine through the liquid inlet 11 of the central distributor 7, the light density of gas allows for complete emptying of the liquid inside the filling machine without releasing it through the filling valve 8 to avoid external contamination. Alternatively, cleaning media can be introduced to perform simple cleaning operations inside the equipment.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
