Description

Technical Field

[0001] This utility model relates to the field of pipeline anti-blocking technology, specifically an automatic tapping device for preventing blockage in magnesium oxide negative pressure receiving pipelines. Background Technology

[0002] Magnesium oxide is an inorganic compound composed of magnesium and oxygen. It is a white solid, usually existing in the form of powder or granules. Magnesium oxide has a wide range of applications in industry and daily life. It is commonly transported using negative pressure receiving pipes. The negative pressure receiving system creates a negative pressure environment to transport powdered materials such as magnesium oxide from one place to another.

[0003] Because magnesium oxide has strong adhesion, during pneumatic conveying, magnesium oxide powder will adhere to the pipe wall as it flows through the pipe, especially in horizontal sections and bends. If too much magnesium oxide powder accumulates, it can easily cause pipe blockage and affect the normal use of the pipe. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic knocking device for preventing blockage in magnesium oxide negative pressure receiving pipes. It has the advantage of preventing pipe blockage and solves the problem that magnesium oxide has strong adhesion, and during pneumatic conveying, magnesium oxide powder will adhere to the pipe wall during pipe flow, especially in horizontal sections and bends. If too much magnesium oxide powder accumulates, it can easily lead to pipe blockage and affect the normal use of the pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic knocking device for preventing blockage in a magnesium oxide negative pressure receiving pipe, comprising a housing, wherein a vibration knocking mechanism is provided on the housing;

[0006] The vibration striking mechanism includes a motor fixedly mounted on the outer surface of the housing. A rotating shaft is fixedly mounted at the output end of the motor, penetrating into the interior of the housing and rotatably connected to the inner surface of the housing. An eccentric shaft and two circular blocks are fixedly mounted on the surface of the rotating shaft. Arc-shaped protrusions are fixedly mounted on the surface of the circular blocks. Two top springs are fixedly mounted on the lower surface of the inner housing. A circular plate is fixedly mounted on the top of the top spring. A semi-circular block that contacts the surface of the circular block is fixedly mounted on the upper surface of the circular plate. A connecting rod penetrating into the lower surface of the housing is fixedly mounted on the lower surface of the circular plate. A crossbar is fixedly mounted on the bottom of the connecting rod. Multiple striking blocks are fixedly mounted on the surface of the crossbar. A controller is fixedly mounted on the upper surface of the housing. The surface of the housing is provided with mounting components.

[0007] Furthermore, a circular hole communicating with the interior of the outer shell is provided on the lower surface of the outer shell, and the connecting rod is located inside the circular hole, with the outer surface of the connecting rod in sliding contact with the inner surface of the circular hole.

[0008] The advantage of adopting the above-mentioned further solution is that it facilitates the movement and extension of the connecting rod on the outer casing.

[0009] Furthermore, the output terminal of the controller is electrically connected to the input terminal of the motor.

[0010] The advantage of adopting the above-mentioned further solution is that it facilitates the control and setting of the motor's start and stop via the controller.

[0011] Furthermore, the mounting assembly includes a connecting block fixedly mounted on the lower surface of the housing. Four arc-shaped clamps are rotatably mounted on the surface of the connecting block. A fixing block is fixedly mounted at the bottom of the arc-shaped clamps. A threaded hole is opened on the surface of the fixing block, and a fixing threaded rod is threadedly connected inside the threaded hole.

[0012] The advantage of adopting the above-mentioned further solution is that by setting up the installation components, it is easy to fix the housing in the position where the pipe needs to be hit.

[0013] Furthermore, a rubber pad is fixedly installed on the lower surface of the outer shell, and an arc-shaped groove is formed on the surface of the rubber pad. The rubber pad is located between two adjacent connecting blocks.

[0014] The beneficial effect of adopting the above-mentioned further solution is that setting rubber pads helps to improve the stability of the casing after installation.

[0015] Furthermore, a mounting bracket is fixedly installed on the surface of the motor, and the mounting bracket is fixedly connected to the surface of the outer casing.

[0016] The beneficial effect of adopting the above-mentioned further solution is that setting a fixed frame helps to improve the stability of the motor during operation.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] This automatic anti-clogging striking device for magnesium oxide negative pressure receiving pipes uses an eccentric shaft and a striking block that can be repeatedly raised and lowered within the outer casing to vibrate and strike the pipe. This removes magnesium oxide powder adhering to the inner wall of the pipe, solving the problem that magnesium oxide has strong adhesion and tends to stick to the pipe wall during pneumatic conveying, especially in horizontal sections and bends. Excessive accumulation of magnesium oxide powder can easily cause pipe blockage and affect the normal use of the pipe. Attached Figure Description

The fixing frame 22 improves the stability of the motor 2 during operation. A rotating shaft 3, penetrating into the interior of the housing 1 and rotatably connected to the inner surface of the housing 1, is fixedly mounted on the output end of the motor 2. An eccentric shaft 4 and two circular blocks 5 are fixedly mounted on the surface of the rotating shaft 3. An arc-shaped protrusion 6 is fixedly mounted on the surface of the circular blocks 5. Two top springs 7 are fixedly mounted on the lower inner surface of the housing 1. A circular protrusion 6 is fixedly mounted on the top of each top spring 7. Plate 8, a semi-circular block 9 is fixedly installed on the upper surface of the circular plate 8, which is in contact with the surface of the circular block 5. A connecting rod 10 is fixedly installed on the lower surface of the circular plate 8, which extends through to the lower surface of the outer shell 1. A circular hole 14 is opened on the lower surface of the outer shell 1, which is connected to the inside of the outer shell 1. The connecting rod 10 is located in the circular hole 14. The outer surface of the connecting rod 10 is in sliding contact with the inner surface of the circular hole 14, which facilitates the movement and extension of the connecting rod 10 on the outer shell 1. A crossbar 11 is fixedly installed at the bottom of the connecting rod 10. A number of striking blocks 12 are fixedly installed on the surface of the crossbar 11. A controller 13 is fixedly installed on the upper surface of the outer shell 1. The output end of the controller 13 is electrically connected to the input end of the motor 2, which facilitates the control and setting of the start and stop of the motor 2 through the controller 13.

[0026] The outer casing 1 has an installation assembly on its surface. The installation assembly includes a connecting block 15 fixedly installed on the lower surface of the outer casing 1. Four arc-shaped clamps 16 are rotatably installed on the surface of the connecting block 15. A fixing block 17 is fixedly installed at the bottom of the arc-shaped clamp 16. The fixing block 17 has a threaded hole 18 on its surface. A fixing threaded rod 19 is threadedly connected inside the threaded hole 18. The installation assembly makes it easy to fix the outer casing 1 at the position where the pipe needs to be hit. A rubber pad 20 is fixedly installed on the lower surface of the outer casing 1. The surface of the rubber pad 20 has an arc groove 21. The rubber pad 20 is located between two adjacent connecting blocks 15. The rubber pad 20 helps to improve the stability of the outer casing 1 after installation.

[0027] The working principle of the above embodiments is as follows:

[0028] In use, place the outer casing 1 on the pipe, so that the rubber pad 20 and the arc groove 21 are in contact with the pipe surface, and the inner side of the arc clamp 16 is in contact with the pipe. Screw the fixing threaded rod 19 into the threaded holes 18 on the corresponding two fixing blocks 17 in sequence, thereby connecting and fixing the bottoms of two adjacent arc clamps 16 together, thus securing the outer casing 1. The controller 13 sets the operating time period of the motor 2. When the motor 2 enters the set time period, it will start, driving the rotating shaft 3 to rotate, causing the eccentric shaft 4 and the circular block 5 to rotate synchronously with the rotating shaft 3. The rotation of the eccentric shaft 4 causes the entire outer casing 1 to vibrate, and the vibration can be transmitted to the pipe through the outer casing 1. When the circular block 5 drives the arc-shaped protrusion 6 to rotate, the arc-shaped protrusion 6 will press the semi-circular block 9, the circular plate 8 and the connecting rod 10 downward, causing the crossbar 11 and the striking block 12 to move downward. The top spring 7 is compressed. During the downward movement of the striking block 12, it will contact the surface of the pipe, and thus knock the pipe. When the arc-shaped protrusion 6 separates from the semi-circular block 9, the top spring 7 will push the circular plate 8 upward, causing the crossbar 11 and the striking block 12 to move upward. Through the repeated separation and contact of the arc-shaped protrusion 6 and the semi-circular block 9, the striking block 12 can knock the pipe multiple times. Under the dual action of knocking and vibration, the magnesium oxide powder adhering to the inner wall of the pipe will be removed.
