Description

Technical Field

[0001] This invention relates to the field of filling production equipment technology, and more specifically to a diversion device in a bottle rinsing machine. Background Technology

[0002] Before containers are filled, they need to be disinfected and cleaned. Bottle rinsing machines are machines specifically designed for cleaning containers.

[0003] Bottle rinsing machines mainly include a distribution device, a container clamping device, and rinsing pipelines. The distribution device includes a distribution plate, whose main function is to distribute the cleaning medium, such as disinfectant or sterile water, to the spray pipelines in the corresponding work areas to achieve the purpose of cleaning the inside of the containers.

[0004] Traditional method: Generally, a diversion device can only distribute one type of medium to achieve disinfection and cleaning of containers. After the containers are cleaned in the bottle rinsing machine, they still need to be drained to remove residual disinfectant. In order to ensure the drainage effect, the bottle rinsing machine needs to have a lot of empty workstations, which leads to a large footprint and increased equipment costs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a gas-liquid two-phase flow splitting device and a bottle rinsing machine, which realizes the flow splitting of two media, has a good sealing and pressure effect between the flow splitting block and the flow splitting plate, and can perform hot air drying on the bottle rinsing machine, which greatly accelerates the speed of liquid draining in the container and effectively saves the space required for filling production equipment.

[0006] To solve the above problems, the technical solution adopted by the present invention is: a gas-liquid two-phase flow splitting device, comprising: a flow splitting plate, and a mounting block located above the flow splitting plate. Both the mounting block and the flow splitting plate are sleeved on a fixedly installed hanging rod. The mounting block is fixed to the hanging rod. An annular mounting groove is formed at the bottom of the mounting block, and the mounting groove is concave upward. An annular medium flow splitting block is embedded in the mounting groove. The medium flow splitting block is provided with mutually isolated gas chambers and liquid chambers. The medium flow splitting block is provided with a flow splitting block inlet and a flow splitting block exhaust port that communicate with the gas chambers and are connected to the liquid chambers. The distribution block has a liquid inlet and a liquid outlet. The air inlet is located on the side wall of the distribution block outside the gas chamber. The exhaust port is located at the bottom of the distribution block. The liquid inlet and the liquid outlet are located at the top and bottom of the distribution block, respectively.

Several elastic pressure blocking components are installed between the pressure plate and the mounting block. The structure of each elastic pressure blocking component includes: a compression spring, the upper and lower ends of which press against the bottom of the pressure plate and the spring seat, respectively. The spring seat is set on the pressure blocking post, and the lower end of the pressure blocking post passes through the mounting block and extends to the top of the media distribution block. Under the action of each compression spring, the lower end of each pressure blocking post presses against the top of the media distribution block, thereby sealing the media distribution block against the distribution plate.

[0011] Furthermore, in the aforementioned gas-liquid two-phase flow splitting device, a support block is also provided on the support seat of the hanger rod, and the support block is supported on the bottom of the mounting block.

[0012] Furthermore, in the aforementioned gas-liquid two-phase flow splitting device, an upper wear-resistant ring and a lower wear-resistant ring are provided outside the support block. The upper wear-resistant ring is locked on the locking step on the outer wall of the upper end of the support block, and the lower wear-resistant ring is locked on the support base. The flow splitting disk is fitted outside the upper wear-resistant ring and the lower wear-resistant ring.

[0013] A bottle rinsing machine includes a rotating base capable of rotation. Around the rotating base are arranged a bottle-feeding area for feeding containers, a turning area for turning containers to a mouth-down position, a washing area for washing the inside of the containers, a drying area for drying the inside of the containers with hot air, and a bottle-discharging area for discharging the containers.

The liquid inlet 421 and liquid outlet 422 of the diverter block are located at the top and bottom of the medium diverter block 4, respectively. In this embodiment, the air inlet 411 of the diverter block is opened along the circumference of the medium diverter block 4, and the air inlet 411 is a angular groove with a larger outer opening and a smaller inner opening.

The first sealing ring 401 and the second sealing ring 402 are spaced apart between the outer wall of the medium diverter block 4 and the mounting groove 21, and are located on the upper and lower sides of the diverter block air inlet 411 of the medium diverter block 4. The third sealing ring 403 is located between the inner wall of the medium diverter block 4 and the mounting groove 21, and is located at the opening of the groove 21.

[0022] A pressure plate 7 is provided above the mounting block 2, and the pressure plate 7 is fixed to the mounting block 2. Several elastic pressure blocking components are provided between the pressure plate 7 and the mounting block 2. Specifically, the fixing structure between the pressure plate 7 and the mounting block 2 includes: at least two evenly distributed connecting posts 8, the lower end of each connecting post 8 is fixed to the mounting block 2, several connecting holes are opened on the pressure plate 7, the upper end of each connecting post 8 passes through a connecting hole, and the upper end of each connecting post 8 is provided with an upper locking nut 81 and a lower locking nut 82, which are respectively locked to the top and bottom of the pressure plate 7.

[0023] Each elastic pressure block assembly includes a compression spring 9, with its upper and lower ends pressing against the bottom of the pressure plate 7 and the spring seat 10, respectively.

[0024] The pressure plate 7 and the mounting block 2 adopt the above-mentioned fixing structure. The purpose is to adjust the spring force of the compression spring by adjusting the distance between the pressure plate 7 and the mounting block 2, thereby ensuring the sealing and pressure effect between the medium diversion block 4 and the diversion plate 1.

[0025] The outer wall of the distribution plate 1 is provided with a number of liquid connectors 101 and a number of gas connectors 102. Each liquid connector 101 is connected to the outlet of a liquid channel 103 in the distribution plate 1, and the liquid inlet 1031 of each liquid channel 103 is located at the top of the distribution plate 1. Each gas connector 102 is connected to the gas outlet of a gas channel 104 in the distribution plate 1, and the gas inlet 1041 of each gas channel 104 is also located at the top of the distribution plate 1.

[0026] The distribution plate 1 can rotate relative to the boom 3. When the liquid inlet 1031 of any liquid channel 103 on the distribution plate 1 rotates to connect with the liquid outlet 422 of the distribution block, the corresponding liquid connector 101 can output liquid to the outside.

[0027] When the gas inlet 1041 of any gas channel 104 on the distributor plate 1 is rotated to connect with the exhaust port 412 of the distributor block, the corresponding gas connector 102 can output gas to the outside.

[0028] like Figure 4 As shown, a bottle rinsing machine 100 includes a rotating base 12. Around the rotating base 12, a bottle feeding area 1001 for feeding containers, a turning area 1002 for turning containers to a mouth-down position, a washing area 1003 for washing the inside of the containers, a drying area 1004 for drying the inside of the containers with hot air, and a bottle output area 1005 for outputting the containers. Several workstations 1006 are evenly spaced on the rotating base 12. As the rotating base 12 rotates, the workstations 1006 sequentially pass through the bottle feeding area 1001, the turning area 1002, the washing area 1003, the drying area 1004, and the bottle output area 1005. The diverter plate 1 is fixed to the rotary seat 12; the diverter block air inlet 411 and diverter block exhaust port 412 are opened on the gas inlet 1041 inside the drying zone 1004, and the diverter block liquid inlet 421 and diverter block liquid outlet 422 are opened on the gas inlet 1041 inside the washing zone 1003; each liquid connector 101 and each gas connector 102 on the diverter plate 1 corresponds to a station 1006 on the rotary seat 12.

[0029] The working principle is as follows: Each container is fed into a station 1006 of the rinsing machine 100 via the bottle loading area 1001. As the rotary table 12 rotates, it first enters the flipping area 1002 and is flipped so that its opening is facing down, and then enters the washing area 1003. The liquid inlet 1031 of the liquid channel 103 corresponding to the station 1006 entering the washing area 1003 is connected to the drain outlet 422 of the diversion block, and the corresponding liquid connector 101 supplies detergent to the station 1006 to sterilize and clean the containers, thereby achieving sterilization and cleaning of the containers in the station 1006. After washing, the containers enter the drying zone 1004. At station 1006, the liquid inlet 1031 of the liquid channel 103 is redirected away from the drain outlet 422 of the distribution block, and the gas inlet 1041 of the corresponding gas channel 104 is rotated to connect with the exhaust outlet 412 of the distribution block. The corresponding gas connector 102 supplies drying gas to station 1006 to accelerate the drying process inside the container. After drying, the containers leave the drying zone 1004 and enter the bottle outlet zone 1005. In the bottle outlet zone 1005, the gas inlet 1041 of the gas channel 104 corresponding to station 1006 is redirected away from the exhaust outlet 412 of the distribution block. The dried containers are then output through the bottle outlet zone 1005.

[0030] The advantages of this invention are: it provides a gas-liquid two-phase flow splitting device and a bottle rinsing machine. The gas-liquid two-phase flow splitting device has a simple structure and achieves the splitting of two media. The sealing effect between the media splitting block 4 and the splitting plate 1 is good, and the pressure of the compression spring 9 has a self-compensating sealing effect at the end face, greatly improving the service life of each component. Hot air drying can be performed on the bottle rinsing machine, which greatly accelerates the drainage speed of the liquid in the container and effectively saves the space required for filling production equipment.
