Description

Technical Field

[0001] The utility model relates to the technical field of liquid supply equipment, in particular to a liquid pressurizer and a liquid discharge device. Background Art

[0002] In the existing technology, some filling production lines use compressed air at higher than atmospheric pressure to press the liquid out of the container. However, the various matching components are installed separately and cannot be applied to different containers. This means that different containers must be equipped with separate liquid-pressing components, resulting in a waste of resources.

[0003] In addition, it is difficult to adjust the air pressure in the container as needed in the existing technology, resulting in the inability to adapt to liquids with different viscosities, densities, surface tensions, etc., and the equipment has poor applicability. Utility Model Content

[0005] To achieve the above-mentioned object, the first aspect of the present invention provides a hydraulic pressurizer, comprising:

The air inlet valve is opened, and compressed air is introduced into the container through the air inlet pipe. The pressure display unit detects whether the pressure in the container has reached the required pressure value, so that the liquid can flow out of the liquid outlet pipe at the required flow rate. When the pressure in the container exceeds the rated pressure, the air pressure safety valve opens to release the pressure.

[0025] The hydraulic press as a whole has a cover body detachably connected to the container, so that the entire hydraulic press can be installed on and removed from the container, and installed on different containers, so that the hydraulic press can be adapted to different containers, improving the adaptability of the hydraulic press and saving resources.

[0036] This embodiment provides a liquid pressurizer for conveying liquids, so that the liquid pressurizer is adaptable to different containers and is suitable for liquids with different viscosities, densities and surface tensions, thereby improving the adaptability of the liquid pressurizer.

[0037] like Figure 1 As shown, the liquid press provided in this embodiment includes a cover body 1, an air inlet pipe 2, an air inlet valve 3, an air pressure safety valve 4, a pressure display unit 5 and a liquid outlet pipe 6. Among them, the cover body 1 can be detachably covered on the opening of the container (not shown in the figure), and a first through hole and a second through hole are provided on the cover body 1. The air inlet pipe 2 is sealed and inserted in the first through hole. The air inlet valve 3 is connected to the air inlet pipe 2, and the air inlet valve 3 can control the on and off of the air inlet pipe 2. The air pressure safety valve 4 is connected to the air inlet pipe 2. When the pressure of the air inlet pipe 2 is higher than the rated pressure of the air pressure safety valve 4, the air pressure safety valve 4 can be opened, and the rated pressure of the air pressure safety valve 4 is adjustable. The pressure display unit 5 can display the air pressure in the air inlet pipe 2. The liquid outlet pipe 6 is sealed and inserted in the second through hole.

[0038] When using the liquid press, cover 1 is placed on the container, air inlet pipe 2 is located above the liquid level, and the lower end of liquid outlet pipe 6 extends below the liquid level. Open air inlet valve 3, and introduce compressed air into the container through air inlet pipe 2. The pressure display unit 5 detects whether the pressure in the container has reached the required pressure value, so that the liquid can flow out of liquid outlet pipe 6 at the required flow rate. When the pressure in the container exceeds the rated pressure, the air pressure relief valve 4 opens to release the pressure.

[0039] After the cover body 1 is placed on the container, the air inlet pipe 2 is located above the liquid level, and the lower end of the liquid outlet pipe 6 extends into the lower side of the liquid level. Compressed air is introduced into the container and above the liquid through the air inlet pipe 2. The pressure exerted by the compressed air on the liquid will be transmitted equally to all parts of the liquid. Under the action of the compressed air, the liquid will flow out through the liquid outlet pipe 6, thereby transferring the liquid in the container to the desired location.

[0040] The liquid pressurizer provided in this embodiment is a whole, and the cover body 1 is detachably connected to the container, so that the entire liquid pressurizer can be installed on the container and removed from the container, and installed on different containers, so that the liquid pressurizer can be adapted to different containers, thereby improving the adaptability of the liquid pressurizer and saving resources.

[0041] Because the rated pressure of the air pressure safety valve 4 is adjustable, the liquid can be effectively transported and controlled according to the physical properties of the liquid, such as viscosity, density, surface tension, etc., as well as the flow rate of the liquid, thereby improving the practicality of the liquid press. At the same time, for flammable and explosive liquid solvents, the appropriate air pressure and flow rate can be selected to ensure safe transportation.

[0042] Specifically, when adjusting the rated pressure of the air pressure safety valve 4, sufficient compressed air is filled into the container, the screw of the air pressure safety valve 4 is rotated, the air pressure safety valve 4 is adjusted, and it is determined whether the required rated pressure is adjusted according to the pressure displayed by the pressure display unit 5.

[0043] When the liquid press is installed on the container, the lower end of the liquid outlet pipe 6 of the liquid press is preferably close to the bottom of the container, such as the distance between the lower end of the liquid outlet pipe 6 and the bottom of the container is 0.5-1 cm, so that the liquid enters the liquid outlet pipe 6 through the gap between the lower end of the liquid outlet pipe 6 and the bottom of the container, and at the same time the liquid in the container can be drained as cleanly as possible.

[0044] Optionally, the length of the liquid outlet pipe 6 is adjustable, so that the liquid outlet pipe 6 can adapt to containers of different depths.

[0045] Optionally, the liquid outlet pipe 6 is made of plastic or metal. For example, the plastic is polypropylene random copolymer (PPR). The length of the liquid outlet pipe 6 can be adjusted by cutting, but this method can only shorten the liquid outlet pipe 6 and is difficult to lengthen.

[0046] Preferably, the liquid outlet pipe 6 includes a plurality of detachably connected sub-pipes, and the purpose of lengthening or shortening the liquid outlet pipe 6 is achieved by connecting different numbers of sub-pipes. Furthermore, the sub-pipes are provided with threads, and two adjacent sub-pipes are detachably connected by the threads to quickly adjust the length of the liquid outlet pipe 6.

[0047] Optionally, the liquid outlet pipe 6 includes a horizontal pipe 61 and a vertical pipe 62, which are connected to form an L-shaped structure. The horizontal pipe 61 extends horizontally, and the vertical pipe 62 extends vertically. Exemplarily, the vertical pipe 62 includes one or more sub-pipes connected in sequence. The L-shaped structure of the liquid outlet pipe 6 facilitates insertion into a container and facilitates alignment of the outlet of the liquid outlet pipe 6 with another container for receiving the solution.

[0048] Optionally, the intake pipe 2 includes a first air pipe 21 and a second air pipe 22. The air pressure safety valve 4 and the pressure display unit 5 are connected to the first air pipe 21. One end of the second air pipe 22 is connected to the first air pipe 21, and the other end can be connected to an air compressor. The second air pipe 22 facilitates connection to the air compressor. The pressure display unit 5, the air pressure safety valve 4, and the intake valve 3 are installed separately on the first air pipe 21 and the intake pipe 2, thereby facilitating installation of the pressure display unit 5, the air pressure safety valve 4, and the intake valve 3.

[0049] Exemplarily, the other end of the second air pipe 22 is connected with a quick-release connector or provided with threads, and the pipeline of the air compressor is correspondingly provided with a quick-release connector or threads so as to be quickly connected to the second air pipe 22 .

[0050] Optionally, the air pressure safety valve 4 is connected to the upper end of the first air pipe 21 to facilitate connection to the air pressure safety valve 4. Air pressure safety valves 4 with adjustable rated pressure are prior art, and the structure of the air pressure safety valve 4 is not the inventive point of the present invention. Therefore, its specific structure and operating principle are not described in detail here. The pressure display unit 5 can be a pressure gauge, which is prior art, and therefore, its specific structure and operating principle are not described in detail here. The air inlet valve 3 can be a solenoid valve or a manually rotated valve, without limitation here.

[0051] Optionally, a first sealing member is provided between the intake pipe 2 and the first through hole. For example, the first sealing member may be a raw tape, which is wrapped around the outside of the intake pipe 2. The tape-wrapped intake pipe 2 forms an interference fit with the first through hole, thereby achieving a sealed connection between the intake pipe 2 and the first through hole. Of course, the first sealing member may also be a sealing ring, etc., which is sleeved around the outside of the intake pipe 2, thereby achieving a sealed connection between the intake pipe 2 and the first through hole.

[0052] A second sealing member is provided between the liquid outlet pipe 6 and the second through hole. For example, the second sealing member may be a raw tape. The raw tape is wrapped around the liquid outlet pipe 6. The tape-wrapped liquid outlet pipe 6 forms an interference fit with the second through hole, thereby achieving a sealed connection between the liquid outlet pipe 6 and the second through hole. Of course, the second sealing member may also be a sealing ring, etc., which is sleeved around the liquid outlet pipe 6 to achieve a sealed connection between the liquid outlet pipe 6 and the second through hole.

[0053] Optionally, the cover 1 is provided with a thread for connecting to the container, thereby realizing a quick connection between the cover 1 and the container. Optionally, a third sealing member can be provided between the cover 1 and the container to realize a sealed connection between the cover 1 and the container to avoid air leakage.

[0054] Optionally, the lid body 1 includes a cap 11 and a ring 12. The ring 12 is connected to the lower end of the cap 11. The diameter of the cap 11 is larger than the diameter of the ring 12. The ring 12 is further provided with an external thread for connecting to the container. For example, a third sealing member, such as a sealing ring, may be provided between the cap 11 and the container.

[0055] This embodiment also provides a liquid discharge device, comprising a container and the aforementioned liquid pressurizer. The container is capable of containing liquid, the liquid pressurizer's air inlet pipe 2 is located above the liquid surface, and the lower end of the liquid discharge pipe 6 of the liquid pressurizer extends below the liquid surface and close to the bottom of the container. For example, the distance between the lower end of the liquid discharge pipe 6 and the bottom of the container is 0.5-1 cm, so that liquid can enter the liquid discharge pipe 6 through the gap between the lower end of the liquid discharge pipe 6 and the bottom of the container, while simultaneously draining the liquid from the container as much as possible. The liquid discharge device provided in this embodiment can provide liquids with different physical properties such as viscosity, density, and surface tension, and has strong applicability.
