Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum branch pipes, and specifically relates to a new type of high-efficiency vacuum branch pipe. Background Technology

[0002] The suction range of a main vacuum cleaner is limited and cannot directly cover all areas that need cleaning. The suction hose extends the suction power to distant or hard-to-reach locations (such as high places, corners, and inside equipment). Operators can work flexibly over a large area without moving the main unit. At the same time, factories, workshops, or large equipment often have multiple dust-generating points. If each point is equipped with a vacuum cleaner, it is costly and takes up space. Using a suction branch hose distributes the suction power of a high-powered vacuum cleaner to multiple dust-generating points, thereby reducing costs and allowing one main unit to serve multiple workstations. This facilitates centralized management, unified collection, and unified processing. Therefore, a branch hose is needed for auxiliary vacuuming.

[0003] Most existing vacuum branch pipes have several branch pipes connected to the end of the main pipe. These branch pipes can be removed from the main pipe to facilitate the cleaning of impurities inside the pipe. Using branch pipes can improve vacuuming efficiency. Although it can meet the need to remove the branch pipes from the main pipe, in this method, the branch pipes are connected to the main pipe by mounting brackets and bolts, which makes them inconvenient to remove. Cleaning the blocked branch pipes requires disassembling the bolts one by one, which is cumbersome. The bolts may be corroded or stripped due to long-term use, making disassembly even more difficult. This results in a single maintenance taking tens of minutes or even longer, increasing labor intensity and causing the production line to be shut down for a long time, affecting the production schedule. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a new type of high-efficiency vacuum branch pipe. By setting a first fixed sleeve and a second fixed sleeve, the insert plate on the second fixed sleeve cooperates with the slot on the first fixed sleeve, which can facilitate the disassembly of the main pipe and the branch pipe by the staff, thereby reducing the labor intensity of the staff and improving the cleaning efficiency of the branch pipe.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a novel high-efficiency dust collection branch pipe, the left end of the branch pipe is connected to the main pipe, a fixing unit is provided between the main pipe and the branch pipe, the fixing unit includes a fixing sleeve one provided at the right end of the main pipe, the fixing sleeve one has a slot inside, the left end of the branch pipe is provided with a fixing sleeve two, the left side wall of the fixing sleeve two is provided with an insert plate adapted to the slot, the upper end of the fixing sleeve one is provided with a mounting bracket, and the mounting bracket is provided with a fixing component for fixing the insert plate inside.

[0006] As a further improvement of this utility model, the fixing component includes a sliding plate slidably disposed inside the mounting frame. A pull rod is provided at the upper end of the sliding plate, and a pull ring is provided at the upper end of the pull rod extending to the outer end of the mounting frame. A through hole adapted to the pull rod is provided on the mounting frame, and the pull rod is slidably connected to the mounting frame. An insertion rod is provided at the lower end of the sliding plate, and an insertion hole adapted to the insertion rod is provided at the end of the insertion plate. A through hole adapted to the insertion rod is provided on the side wall of the fixing sleeve II. Several springs are connected between the sliding plate and the mounting frame. One end of the spring is connected to the outer side wall of the sliding plate, and the other end is connected to the inner side wall of the mounting frame.

[0007] As a further improvement of this utility model, there are four mounting brackets.

[0008] As a further improvement of this utility model, a dust collection hood is provided at the right end of each branch pipe. The shape of the dust collection hood (such as a trumpet shape) is designed by fluid dynamics to guide the airflow and form a uniform and stable negative pressure zone (suction zone) in front of the hood opening. This allows the airflow to "envelop" the pollution source and quickly pull the generated dust into the pipe to prevent its diffusion, reduce turbulence and eddies, and avoid the dust being "blown away" by the airflow, thereby achieving a higher capture rate and cleaner air in the working area.

[0009] As a further improvement of this utility model, there are two branch pipes, which are connected to the main pipe.

[0010] As a further improvement of this utility model, a dust pump is installed at the left end of the main pipe. When the dust pump is working, it generates a continuous negative pressure (vacuum) at the inlet of the main pipe. This negative pressure is transmitted to each dust collection hood through the main pipe and branch pipes, forming a "suction". This ensures that the dust pump can provide a stable and reliable air volume and air pressure regardless of the length or number of branch pipes, ensuring that each dust collection point (dust collection hood) has sufficient capture capacity to effectively suck up dust, debris and smoke, and improve dust collection efficiency. At the same time, the dust pump is centrally located at one end of the main pipe to form an independent power module. When maintaining or replacing it, only this module needs to be operated, without affecting the pipeline network. The pump body is usually easy to access and convenient for maintenance, thus making equipment maintenance convenient and downtime short.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, by setting up a fixed sleeve one and a fixed sleeve two, the insert plate on the fixed sleeve two cooperates with the slot on the fixed sleeve one, which can facilitate the disassembly of the main pipe and branch pipes. The tool-free quick-installation structure with quick-connect couplings and buckles can achieve "one push to connect, one pull to open", clearing blocked branch pipes. The operation time is shortened from 5-10 minutes of traditional bolt connection to 10-30 seconds. Maintenance personnel can quickly complete multi-point cleaning without carrying wrenches and other tools, which can drastically reduce production line downtime and significantly improve production efficiency. The benefits are especially great in factories with multiple shifts and continuous production, reducing operation and maintenance costs.

[0012] Secondly, by installing a vacuum pump, a continuous negative pressure (vacuum) is generated at the main pipe inlet when the vacuum pump is working. This negative pressure is transmitted to each dust collection hood opening through the main pipe and branch pipes, forming a "suction". This ensures that the vacuum pump can provide a stable and reliable air volume and air pressure regardless of the length or number of branch pipes, ensuring that each dust collection point (dust collection hood) has sufficient capture capacity to effectively suck up dust, debris and smoke, and improve vacuuming efficiency.

[0013] Third, by setting up a dust collection hood, the opening area of ​​which is larger than the opening of the branch pipe, a "collection funnel" is formed. This can cover a larger contaminated area, thereby significantly increasing the effective suction radius. There is no need to precisely align the small pipe opening with the source of pollution. Even if there is an operational deviation, it can effectively capture splashed dust and debris, greatly improving suction efficiency and reducing the escape of pollutants into the environment.

[0014] Fourth, by setting up branch pipes, the dust collection points are connected to the main pipe "nearest away", which shortens the airflow path and reduces the resistance along the pipe and local resistance. This allows each dust collection point to obtain higher effective negative pressure and air volume, achieving the effect of fast capture speed and no dust diffusion. Attached Figure Description

Detailed Implementation

[0018] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0019] like Figure 1 , 2 As shown in Figure 3, a novel high-efficiency vacuum branch pipe is provided. The left end of the branch pipe 106 is connected to the main pipe 101. A fixing unit is provided between the main pipe 101 and the branch pipe 106. The fixing unit includes a fixing sleeve 102 located at the right end of the main pipe 101. The fixing sleeve 102 has a slot 103 inside. The left end of each branch pipe 106 is provided with a fixing sleeve 204. The left side wall of the fixing sleeve 204 is provided with an insert plate 105 that is compatible with the slot 103. The upper end of the fixing sleeve 102 is provided with a mounting bracket 201. The mounting bracket 201 has a fixing component inside for fixing the insert plate 105.

[0020] like Figure 2 , 3As shown, the fixing component includes a sliding plate 202 slidably disposed inside the mounting bracket 201. A pull rod 203 is provided at the upper end of the sliding plate 202. A pull ring 204 is provided at the upper end of the pull rod 203 extending to the outer end of the mounting bracket 201. A through hole is provided on the mounting bracket 201 to match the pull rod 203. The pull rod 203 is slidably connected to the mounting bracket 201. A insertion rod 205 is provided at the lower end of the sliding plate 202. A through hole is provided on the side wall of the fixing sleeve 104 to match the insertion rod 205. An insertion hole 206 is provided at the end of the insertion plate 105 to match the insertion rod 205. The sliding plate 202 and the mounting bracket 201 are connected... Several springs 207 are connected, with one end of each spring 207 connected to the outer wall of the slide plate 202 and the other end connected to the inner wall of the mounting bracket 201. When the branch pipe 106 needs to be disassembled, first pull the pull ring 204 outward. The pull ring 204 drives the pull rod 203 to move away from the mounting bracket 201, which in turn causes the pull rod 203 to drive the slide plate 202 to compress the springs 207 and move away from the mounting bracket 201. The slide plate 202 then drives the insertion rod 205 to move, causing it to disengage from the insertion hole 206 of the insertion plate 105. Next, the branch pipe 106 is pulled to the right, causing the insertion plate 105 to disengage from the fixing sleeve. The branch pipe 106 can be disassembled from the slot 103 inside the second 104 for easy cleaning. When the branch pipe 106 needs to be installed, first move the insert plate 105 of the fixing sleeve 102 of the branch pipe 106 into the slot 103 on the side wall of the fixing sleeve 104. During the movement, gently pull the pull ring 204, so that the pull rod 203 drives the insert rod 205 to move away from the mounting bracket 201 through the sliding plate 202, so that the insert rod 205 abuts against the insert plate 105. Continue to push the insert plate 105 into the slot 103 until the insert rod 205 is pushed into the slot 103 by the spring 207. The insertion hole 206 is used to fix the fixing sleeve 104, thereby fixing the branch pipe 106 and facilitating its disassembly. The tool-free quick-installation structure, using quick-connect connectors and clips, achieves "one push to connect, one pull to open". Clearing the blocked branch pipe 106 reduces the operation time from 5-10 minutes of traditional bolted connections to 10-30 seconds. Maintenance personnel can quickly complete multi-point cleaning without carrying wrenches or other tools, which can drastically reduce production line downtime and significantly improve production efficiency. This is especially beneficial in factories with multiple shifts and continuous production, reducing operation and maintenance costs.

[0021] like Figure 1 , 4 As shown, there are 4 mounting brackets 201.

[0022] like Figure 1 , 4As shown, each branch pipe 106 is provided with a dust collection hood 301 at its right end. The opening area of ​​the dust collection hood 301 is larger than the pipe opening of the branch pipe 106, forming a "collection funnel". It can cover a larger pollution area, thereby significantly increasing the effective dust collection radius. There is no need to precisely align the small pipe opening with the pollution source. Even if there is an operational deviation, it can effectively capture splashed dust and debris, greatly improve dust collection efficiency, and reduce the escape of pollutants into the environment.

[0023] like Figure 1 , 4 As shown, there are two branch pipes 106, which are connected to the main pipe 101.

[0024] When in use, the vacuum pump 302 is started, and the vacuum pump 302 generates a continuous negative pressure at the inlet of the main pipe 101. This negative pressure is transmitted to the inlets of each dust collection hood 301 through the main pipe 101 and the branch pipes 106, forming a "suction". This ensures that the vacuum pump 302 can provide a stable and reliable air volume and air pressure regardless of the length or number of branch pipes 106, ensuring that each vacuum point (dust collection hood 301) has sufficient capture capacity to effectively suck up dust, debris and smoke, and thus absorb dust and other substances.

[0025] After a period of operation, dust and other debris may remain inside the branch pipe 106. When disassembling the branch pipe 106, first pull the pull ring 204 outwards. The pull ring 204 moves the pull rod 203 away from the mounting bracket 201, causing the pull rod 203 to move the slide plate 202 and compress the spring 207 away from the mounting bracket 201. The slide plate 202 then moves the insertion rod 205, disengaging it from the insertion hole 206 of the insertion plate 105. Next, pull the branch pipe 106 to the right, disengaging the insertion plate 105 from the slot 103 inside the fixing sleeve 104. This allows the branch pipe 106 to be disassembled for cleaning. When installing the branch pipe 106, first move the insertion plate 105 of the fixing sleeve 102 into the slot 103 on the side wall of the fixing sleeve 104. During this movement, gently pull... Pull ring 204 causes pull rod 203 to move insert rod 205 away from mounting bracket 201 via slide plate 202, thereby causing insert rod 205 to abut against insert plate 105 and continue to push insert plate 105 into slot 103 until insert rod 205 is inserted into insert hole 206 under the action of spring 207, thus completing the fixation of fixing sleeve 104 and fixing branch pipe 106. This facilitates the disassembly of branch pipe 106. The tool-free quick-installation structure using quick-connect couplings and clips achieves "one push to close, one pull to open", clearing blocked branch pipe 106. The operation time is shortened from 5-10 minutes of traditional bolt connection to 10-30 seconds. Maintenance personnel can quickly complete multi-point cleaning without carrying wrenches or other tools, which can drastically reduce production line downtime and significantly improve production efficiency. This is especially beneficial in factories with multiple shifts and continuous production, reducing operation and maintenance costs.

[0026] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, a vacuum pump 302 is installed at the left end of the main pipe 101. When the vacuum pump 302 is working, it generates a continuous negative pressure (vacuum) at the inlet of the main pipe 101. This negative pressure is transmitted to the openings of each dust collection hood 301 through the main pipe 101 and the branch pipe 106, forming a "suction". This ensures that the vacuum pump 302 can provide a stable and reliable air volume and air pressure regardless of the length or number of branch pipes 106, ensuring that each dust collection point (dust collection hood 301) has sufficient capture capacity to effectively suck up dust, debris and smoke, and improve the dust collection efficiency.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
