Description

Technical Field

[0001] This utility model relates to the field of unblocking device technology, and in particular to a high-low pressure mixed injection unit. Background Technology

[0002] Existing pneumatic unblocking units are widely used in the unblocking field. Currently, the injection units of pneumatic unblocking devices on the market are mainly of two types: high pressure and low pressure. High pressure injection units have high pressure and strong piercing force, but small radiation area. They are prone to forming perforations and depressurization when dealing with large areas of stubborn blockages. Low pressure injection units have large exhaust volume and wide radiation area, but low kinetic energy, making it difficult to move stubborn blockages. Therefore, the existing pneumatic unblocking units that use high and low pressure separately are inconvenient to use. To address this, we provide a high-low pressure hybrid injection unit. Utility Model Content

[0003] The purpose of this invention is to address the limitations of existing pneumatic unblocking units that use separate high-pressure and low-pressure systems, and to provide a high-low pressure mixed injection unit.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a high-low pressure mixed injection unit, comprising: an injection mechanism, the injection mechanism including an annular splitter pipe, a low-pressure injection pipe sleeved inside the annular splitter pipe, a high-pressure injection pipe provided on one side of the annular splitter pipe, the number of high-pressure injection pipes being six, a side spray groove being opened at one end of the high-pressure injection pipe, and a connecting mechanism provided on one side of the annular splitter pipe, the connecting mechanism including a threaded pipe.

[0005] In a preferred embodiment, the low-pressure nozzle is fixedly connected to the annular splitter pipe, and a retainer is sleeved on the outer surface of the low-pressure nozzle and the high-pressure nozzle. The retainer is fixedly connected to the low-pressure nozzle and slidably connected to the high-pressure nozzle.

[0006] In a preferred embodiment, one end of the low-pressure nozzle is provided with a threaded connector, which is fixedly connected to the low-pressure nozzle, and the annular splitter pipe is provided with a threaded interface.

[0007] In a preferred embodiment, the threaded tube is fitted inside the annular diverter tube, and the threaded tube is fixedly connected to the annular diverter tube.

[0008] In a preferred embodiment, one end of the threaded tube is provided with an embedded tube, which is fixedly connected to the high-pressure nozzle.

[0009] In a preferred embodiment, a nut is fitted onto the outer surface of the embedded tube, and the nut is fixedly connected to the embedded tube.

[0010] In a preferred embodiment, the nut is fitted onto the outer surface of the threaded pipe, and the nut is threadedly connected to the threaded pipe.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention utilizes a spraying mechanism with both low-pressure and high-pressure nozzles. This mechanism first penetrates the surrounding area of ​​stubborn blockages, loosening them before using low-pressure air to remove the blockage. This results in better and more efficient clearing of stubborn blockages, overcoming the limitations of using low-pressure or high-pressure nozzles separately. Furthermore, a hollow annular distribution pipe ensures that the high-pressure gas entering the pipe is evenly distributed and ejected from the ends of each high-pressure nozzle, effectively clearing stubborn blockages. Finally, a nut is incorporated, allowing for threaded connection with a threaded pipe. This tight connection enables the high-pressure gas from the annular distribution pipe to smoothly enter the high-pressure nozzles and further clear the stubborn blockages.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 like Figures 1-3As shown, this utility model provides a technical solution: a high-low pressure mixed injection unit, including: an injection mechanism 1, the injection mechanism 1 including an annular diverter pipe 11, a low-pressure nozzle 12 sleeved inside the annular diverter pipe 11, a high-pressure nozzle 13 provided on one side of the annular diverter pipe 11, the number of high-pressure nozzles 13 being six, a side spray groove 14 opened at one end of the high-pressure nozzle 13, the low-pressure nozzle 12 being fixedly connected to the annular diverter pipe 11, a retainer 15 sleeved on the outer surface of the low-pressure nozzle 12 and the high-pressure nozzle 13, the retainer 15 being fixedly connected to the low-pressure nozzle 12, the retainer 15 being slidably connected to the high-pressure nozzle 13, a threaded connector 16 provided at one end of the low-pressure nozzle 12, the threaded connector 16 being fixedly connected to the low-pressure nozzle 12, and a threaded interface 17 opened on the annular diverter pipe 11.

[0018] In this embodiment, a low-pressure nozzle 12 with a large diameter is provided, resulting in a large air output. This allows the nozzle to blow and move the blockage material, thus speeding up the cleaning process. A high-pressure nozzle 13 is provided around the low-pressure nozzle 12. When delivering high-pressure air, the high-pressure nozzle 13 can penetrate the stubborn blockage material. Once the blockage is loosened, it can be cleaned by both the low-pressure nozzle 12 and the high-pressure nozzle 13, resulting in a better cleaning effect for stubborn blockages. An annular diverter pipe 11 with a hollow interior is provided, allowing the high-pressure gas entering the annular diverter pipe 11 to be distributed more evenly and ejected from the end of each high-pressure nozzle 13. Side ejection grooves 14 are provided on the high-pressure nozzle 13, allowing the blockage material on the inner wall of the item to be cleaned to be removed by high pressure, thus cleaning the blockage material more thoroughly.

[0019] Example 2 like Figures 1-3 As shown, a connecting mechanism 2 is provided on one side of the annular diverter pipe 11. The connecting mechanism 2 includes a threaded pipe 21, which is sleeved inside the annular diverter pipe 11 and is fixedly connected to the annular diverter pipe 11. One end of the threaded pipe 21 is provided with an embedded pipe 22, which is fixedly connected to the high-pressure nozzle 13. A nut 23 is sleeved on the outer surface of the embedded pipe 22 and is fixedly connected to the embedded pipe 22. The nut 23 is sleeved on the outer surface of the threaded pipe 21 and is threadedly connected to the threaded pipe 21.

[0020] In this embodiment, a connecting mechanism 2 is provided, which can be used in conjunction with the annular diverter pipe 11 and the high-pressure nozzle 13, so that the high-pressure nozzle 13 can be disassembled after installation, thereby making it easier to clean the high-pressure nozzle 13. A nut 23 is provided, which can be threadedly connected to the threaded pipe 21. After the nut 23 is tightly connected to the threaded pipe 21, the high-pressure gas in the annular diverter pipe 11 can smoothly enter the high-pressure nozzle 13 and clean the stubborn blockage.

[0021] Working principle: like Figures 1-3 As shown, in use, the high-pressure nozzle 13 can be installed first. The high-pressure nozzle 13 is then passed through the retainer 15, causing the embedded tube 22 and nut 23 to move. The nut 23 is then fitted onto the outer surface of the threaded tube 21, and the nut 23 is threaded into the threaded tube 21 until they are tightly connected. At this point, the high-pressure nozzle 13 and the low-pressure nozzle 12 will transport airflow under the constraint of the retainer 15. Afterwards, the threaded connector 16 is threaded into the low-pressure air supply pipe, and the high-pressure air supply pipe is connected via a threaded connection. The threaded interface 17 is threadedly connected to the annular splitter pipe 11, which allows air to be supplied to the low-pressure nozzle 12 and the high-pressure nozzle 13 respectively. The high-pressure gas entering the annular splitter pipe 11 can be ejected through the high-pressure nozzle 13, which will break through the stubborn blockage around the blockage and loosen it. The high-pressure gas will also be ejected from the side ejection groove 14 opened on the high-pressure nozzle 13 to clean the inner wall of the item being cleaned. Afterwards, the low-pressure nozzle 12 can eject a large amount of low-pressure gas, which will blow away the stubborn blockage and move it, thereby completely cleaning the stubborn blockage.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
