Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

Therefore, they should not be construed as limitations on the embodiments of the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] The following is combined Figures 1 to 8 This invention describes a vacuum cleaning system according to an embodiment of the present invention.

[0040] like Figure 1-5 As shown, an embodiment of the present invention provides a vacuum cleaning system, including a switching seat 1, a vacuum pipe 3, a vacuum hood 4, and a negative pressure device.

[0041] The switching base 1 has a first blind hole 101 and a second blind hole 102 that are interconnected inside. A cylindrical body 2, communicating with the first blind hole 101, is located on the side of the switching base 1. A suction pipe 3 is slidably disposed inside the cylindrical body 2 and is used to switch between suction and non-suction states. A suction hood 4 is located at the end of the suction pipe 3 facing away from the switching base 1 and is used to seal against the material hopper 5. A powerful negative pressure device provides negative pressure and communicates with the second blind hole 102, used to generate suction through the suction pipe 3 during suction.

[0042] In the vacuuming state, the vacuum pipe 3 moves away from the switching seat 1 so that the vacuum hood 4 is sealed to the hopper 5. The vacuum hood 4 is aligned with the hopper 5 that needs to be cleaned, and the vacuum pipe 3 is connected to the powerful negative pressure device to form a negative pressure suction force, which sucks in the dust or impurities in the hopper 5 through the vacuum hood 4.

[0043] In non-vacuuming state, the vacuum pipe 3 moves toward the switching seat 1 to separate the vacuum hood 4 from the hopper 5, and the vacuum pipe 3 is cut off from the powerful negative pressure device, stopping the vacuuming operation and avoiding safety hazards caused by misoperation.

[0044] Therefore, the dust collection and cleaning system provided in this embodiment of the invention forms a strong negative pressure through a powerful negative pressure device to achieve the dust collection and cleaning effect on the coal powder remaining on the inner wall of the hopper 5. The dust collection pipe 3 is opened and closed with the switching seat 1 to achieve the negative pressure effect of connecting and disconnecting the negative pressure of the dust collection pipe 3.

[0045] In a feasible embodiment of the present invention, a linear mechanism 6 is further included, which is connected to the suction pipe 3. The linear mechanism 6 is used to provide power for the movement of the suction pipe 3. The movement of the suction pipe 3 is driven by the linear mechanism 6, thereby realizing the connection between the suction pipe 3 and the powerful negative pressure device, or the disconnection between the suction pipe 3 and the powerful negative pressure device.

[0046] In vacuuming mode, the user activates the linear mechanism 6, which drives the vacuum pipe 3 to move away from the switching seat 1. When the vacuum pipe 3 moves to the appropriate position, the vacuum hood 4 and the hopper 5 form a sealed connection. At this time, the internal channel of the vacuum pipe 3 is connected to the powerful negative pressure device, forming a negative pressure suction force, which sucks in the dust or impurities in the hopper 5 through the vacuum hood 4.

[0047] In non-vacuuming state, the user restarts the linear mechanism 6, which drives the vacuum pipe 3 to move toward the switching seat 1. When the vacuum pipe 3 moves to the appropriate position, the vacuum pipe 3 separates from the hopper 5. At the same time, the vacuum pipe 3 blocks the first blind hole 101 and the second blind hole 102, and the internal channel of the vacuum pipe 3 is cut off from the powerful negative pressure device, stopping the vacuuming operation.

[0048] The linear mechanism 6 automates the movement of the suction pipe 3, reducing manual operation by the user and improving work efficiency. The powerful negative pressure device provides strong suction to ensure that coal dust is effectively sucked into the suction hood 4, improving the efficiency of dust collection and cleaning.

[0049] like Figure 6 As shown, specifically, a connecting plate 9 is fixedly connected to the top of the suction pipe 3, and a linear mechanism 6 is set on the top of the switching seat 1; the connecting plate 9 is connected to the linear mechanism 6, and the connecting plate 9 is used to provide power for the suction pipe 3 to slide in the cylinder 2.

[0050] By incorporating a top-mounted design with connecting plate 9 and linear mechanism 6, the vacuum cleaning system is not only compact and easy to operate, but also highly efficient and safe, providing users with a better user experience.

[0051] In a feasible embodiment of the present invention, a vacuum main pipe 7 is further included, one end of which is connected to the second blind hole 102 and the other end of which is connected to a powerful negative pressure device; in the vacuuming state, the vacuum pipe 3 is connected to the vacuum main pipe 7, allowing negative pressure to pass through; in the non-vacuuming state, the vacuum pipe 3 is cut off from the vacuum main pipe 7, preventing negative pressure from passing through.

[0052] like Figure 7 and Figure 8As shown, in a feasible embodiment of the present invention, the end of the hopper 5 facing the suction pipe 3 is provided with at least a notch 501 so that the airflow forms a vortex so that the air inlet of the suction pipe 3 forms a certain angle with the hopper 5.

[0053] like Figure 1 As shown, in a feasible embodiment of the present invention, the air inlet of the suction pipe 3 is perpendicular to the direction of the negative pressure airflow. The direction of the negative pressure airflow can be understood as being along the axial direction of the second blind hole 102.

[0054] The air inlet of the vacuum pipe 3 is perpendicular to the direction of the negative pressure airflow. First, when the direction of the negative pressure airflow is perpendicular to the air inlet of the vacuum pipe 3, the airflow will enter the vacuum pipe 3 at a near right angle. This vertical entry method can ensure that the airflow enters the vacuum pipe 3 more concentratedly and stably, reducing the diffusion and loss of airflow, thereby improving the vacuuming efficiency.

[0055] Secondly, the vertical airflow direction also helps prevent dust and impurities from accumulating inside the suction tube 3. Because the airflow enters vertically, dust and impurities are more easily drawn in directly and carried away along the airflow direction, rather than depositing on the tube walls. This helps keep the suction tube 3 clean and unobstructed, further improving suction performance.

[0056] Furthermore, this design can reduce the wear and impact of airflow on the suction pipe 3. Since the airflow enters vertically, rather than directly impacting the inner wall of the suction pipe 3, the wear and impact of airflow on the pipe wall can be reduced, thus extending the service life of the suction pipe 3.

[0057] In summary, the design of the air inlet of the suction pipe 3 being perpendicular to the direction of the negative pressure airflow can improve suction efficiency, keep the suction pipe clean and unobstructed, and reduce the wear and impact of airflow on the suction pipe. This design is very effective and practical in vacuum cleaning systems.

[0058] like Figure 5 As shown, in a feasible embodiment of the present invention, multiple switching seats 1, suction pipes 3, and suction hoods 4 are provided, and they are arranged in a one-to-one correspondence. Each suction hood 4 corresponds to a material bin 5, and each switching seat 1 is connected to the main suction pipe 7. That is, the switching seat 1 is connected in series on the main suction pipe 7, and each switching seat 1 is provided with a suction pipe 3 and a suction hood 4, which can realize the cleaning of multiple workstations.

[0059] In vacuuming mode, the user activates the linear mechanism 6 on each switching seat 1, driving the corresponding vacuum pipe 3 to move in the opposite direction to the switching seat 1. When the vacuum pipe 3 moves to the appropriate position, each vacuum hood 4 will form a sealed connection with the corresponding hopper 5. At this time, each vacuum pipe 3 will be connected to the main vacuum pipe 7. The powerful negative pressure device generates negative pressure suction through the main vacuum pipe 7 and the vacuum pipe 3, sucking the dust or impurities in the corresponding hopper 5 into the vacuum hood 4.

[0060] In non-vacuuming state, the user restarts the linear mechanism 6 on each switching seat 1, driving the corresponding vacuum pipe 3 to move toward the switching seat 1. When the vacuum pipe 3 moves to the appropriate position, each vacuum hood 4 will separate from the corresponding hopper 5. At the same time, each vacuum pipe 3 will be cut off from the corresponding vacuum main pipe 7, the powerful negative pressure device will stop providing negative pressure, and the vacuuming operation will stop.

[0061] Multiple vacuum hoods 4 and vacuum hoses 3 can work simultaneously, greatly improving cleaning efficiency. Furthermore, each vacuum hood 4 can operate independently, allowing for selective cleaning of different material bins 5. Each switching seat 1 and vacuum hose 3 is independent, so even if one malfunctions, it will not affect the normal operation of the others. In addition, the modular design makes the system easy to maintain and replace parts.

[0062] In a feasible embodiment of the present invention, the suction pipe 3 and the suction hood 4 are detachably connected, facilitating the replacement and maintenance of the suction hood 4. The suction pipe 3 and the suction hood 4 can be connected by bolts or other structural means. Additionally, a sealing ring can be provided at the bottom of the suction hood 4 to achieve a sealed connection between the suction hood 4 and the hopper 5. Typically, the sealing ring is made of rubber.

[0063] In one feasible embodiment of the present invention, the dust collection hood 4 is conical, including a large end and a small end. The large end is open and is adapted to fit the hopper 5, ensuring a tight seal with the hopper 5 during dust collection to prevent coal dust leakage. The small end is connected to the dust collection pipe 3, allowing airflow from the hopper 5 through the dust collection hood 4 into the dust collection pipe 3. The dust collection pipe 3 is connected to the side of the dust collection hood 4 to facilitate airflow transmission.

[0064] In one feasible embodiment of the present invention, a weighing device 8 is also included. The weighing device 8 is disposed at the bottom of the silo 5. The weighing device 8 adds real-time monitoring of the material in the silo 5. The weighing device 8 can transmit weight data to the control system for recording and analysis, providing accurate data support for the user. Combined with the control system, relevant operations can be automatically triggered based on the weight of the material in the silo 5.

[0065] In summary, the vacuum cleaning system provided by the present invention has a linear mechanism 6 installed on the top of the switching base 1, a vacuum hood 4 and a vacuum pipe 3 connected together, and the vacuum pipe 3 inserted into the first blind hole 101 of the switching base 1, and the main vacuum pipe 7 inserted into the second blind hole 102 of the switching base 1. The first blind hole 101 and the second blind hole 102 are connected. The hopper 5 is installed on the top of the weighing device 8, and a sealing ring is installed at the large end of the hopper 5. A groove is opened at the interface of the large end for vacuuming and air intake.

[0066] The working principle of the vacuum cleaning system provided by this invention is as follows:

[0067] When the vacuum main pipe 7 forms a strong negative pressure through the powerful negative pressure device.

[0068] When the system is in the dust collection state, negative pressure is formed above the hopper 5 through the switching seat 1, dust collection pipe 3 and dust collection hood 4. The sealing ring at the hopper 5 tightly connects the hopper and the dust collection hood 4. Air enters the hopper 5 through the opening on the hopper and forms a powerful vortex that sweeps the inner wall of the hopper 5 and carries away the coal sample remaining in the hopper 5. The coal sample is then discharged through the dust collection pipe 3 into the dust collection main pipe 7.

[0069] When in non-vacuuming state, that is, when cleaning and vacuuming are off, the vacuum pipe 3 is sealed by the switch seat 1, disconnecting the negative pressure of the vacuum main pipe 7.

[0070] Therefore, the vacuum cleaning system provided by this invention achieves a negative pressure effect by moving the vacuum pipe 3 and opening / closing the switching seat 1, thus connecting and disconnecting the negative pressure of the vacuum pipe 3. The vacuum pipe 3 is connected or disconnected from the main vacuum pipe 7 within the switching seat 1 via a linear mechanism 6, thereby achieving the vacuum cleaning on / off effect. The cyclone vortex phenomenon required for cleaning can be achieved simply by creating a notch in the hopper 5.

[0071] Multiple switching seats 1, linear mechanisms 6, suction pipes 3, and suction hoods 4 can be connected in series on the main suction pipe to clean different hoppers 5 or parts requiring vacuuming and cleaning. These components can be opened simultaneously for cleaning as needed. This invention is highly efficient, simple in structure, low in cost, low in noise, easy to maintain and repair, and flexible in layout.
