Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a dust removal device which does not require shutdown to unload dust. Background Art

[0002] In the silk-making workshop, the cyclone dust collector is mainly used to remove dust from the airflow. The traditional cyclone dust collector mainly includes a cylinder, a cone, an air intake pipe, an exhaust pipe and a dust discharge pipe. The working principle is that the airflow containing dust enters the cylinder from the air intake pipe and forms a vortex in the cone. Under the action of centrifugal force, the dust is forced to leave the airflow, slide down along the cone wall, and finally gather in the dust discharge pipe at the bottom of the cone, while the airflow is discharged through the exhaust pipe.

[0003] At present, when the cyclone dust collector is working, opening the dust discharge pipe to discharge dust will affect the direction of air flow movement inside the cyclone dust collector. Therefore, the dust discharge pipe can only be opened to discharge dust after the cyclone dust collector is shut down, which affects work efficiency. Utility Model Content

[0036] like Figure 1-Figure 5As shown, the utility model is a dust removal device that does not require shutdown to unload dust, including a cylinder 11, a cone 12, an air inlet pipe 13, an exhaust pipe 14 and a dust unloading pipe 15. The dust unloading pipe 15 is provided with a first valve 21 and a second valve 22. The first valve 21 and the second valve 22 can both block the dust unloading pipe 15. It should be noted that the circumference of the first valve 21 and the circumference of the second valve 22 are both provided with a sealing layer to improve the sealing performance of the first valve 21 and the second valve 22. The outer wall of the dust discharge pipe 15 is provided with a mounting plane 151, and the first driving member 31 and the second driving member 32 are mounted on the mounting plane 151. Specifically, two mounting posts 152 are provided on the mounting plane 151, and the first driving member 31 and the second driving member 32 are rotatably mounted on the corresponding mounting posts 152, respectively. In this embodiment, the first driving member 31 and the second driving member 32 are both provided with limiting rings, and the mounting posts 152 are provided with limiting grooves, and the limiting rings are clamped in the limiting grooves to realize the rotational connection between the first driving member 31 and the second driving member 32 and the mounting posts 152. The first driving member 31 is used to drive the first valve 21 to open and close, and the second driving member 32 is used to drive the second valve 22 to open and close. When the dust discharge pipe 15 does not need to be discharged, the first valve 21 is opened, the second valve 22 is closed, and the dust is smoothly collected in the dust discharge pipe 15. When the dust discharge pipe 15 needs to be discharged, the first valve 21 is closed to seal the dust discharge pipe 15, and the second valve 22 is opened to discharge dust. The dust discharge operation can be achieved without stopping the machine, which effectively improves work efficiency.

[0037] In this embodiment, the first driving member 31 is transmission-connected with the second driving member 32, and the rotation directions of the first driving member 31 and the second driving member 32 are opposite. Specifically, the first driving member 31 and the second driving member 32 are both provided with a gear ring 311, and the two gear rings 311 are meshed. Rotating the first driving member 31 or the second driving member 32 can drive the first valve 21 and the second valve 22 to rotate, and the operation is simple, convenient and fast.

[0038] In this embodiment, a first stopper 41 and a second sealing member 52 are provided in the dust discharge pipe 15. The first stopper 41 is used to limit the maximum open position of the first valve 21, and the second sealing member 52 is used to limit the maximum closed position of the second valve 22. A first sealing member 51 and a second stopper 42 are provided in the dust discharge pipe 15. The first sealing member 51 and the second sealing member 52 have the same structure. The first sealing member 51 includes a first sealing strip 511 and a second sealing strip 512. The first sealing strip 511 and the second sealing strip 512 have the same structure, and the first sealing strip 511 is arc-shaped. When the first valve 21 abuts against the corresponding first sealing strip 511 and the second sealing strip 512 at the same time, the first valve 21 is in a closed state, and the sealing performance of the first valve 21 to the dust discharge pipe 15 when the first valve 21 is in a closed state is improved. When the second valve 22 abuts against the corresponding first sealing strip 511 and the second sealing strip 512 at the same time, the second valve 22 is in a closed state, and the sealing performance of the second valve 22 to the dust discharge pipe 15 when the second valve 22 is in a closed state is improved.

[0039] It should be noted that the first limiting member 41 and the second limiting member 42 have the same structure, and are both configured as limiting bars, and can also be configured as limiting columns, limiting protrusions, etc. according to actual conditions, as long as they can play a limiting role.

[0040] A first transmission member is provided between the first driving member 31 and the first valve 21, and the first transmission member is used to make the first valve 21 abut against the first stopper 41. A second transmission member is provided between the second driving member 32 and the second valve 22, and the second transmission member is used to make the second valve 22 abut against the second stopper 42. Specifically, the first transmission member is a first torsion spring 61, one end of the first torsion spring 61 is fixedly connected to the first driving member 31, and the other end is fixedly connected to the first valve 21. In this embodiment, the second transmission member is a second torsion spring 62, one end of the second torsion spring 62 is fixedly connected to the second driving member 32, and the other end is fixedly connected to the second valve 22. The spiral directions of the first torsion spring 61 and the second torsion spring 62 are opposite, and the stiffness of the first torsion spring 61 is greater than the stiffness of the second torsion spring 62. When the first driving member 31 drives the first valve 21 to close via the first torsion spring 61, the second torsion spring 62 keeps the second valve 22 closed. When the second driving member 32 drives the second valve 22 to open via the second torsion spring 62, the first torsion spring 61 keeps the first valve 21 closed.

[0041] Specifically, Figure 5As shown (wherein the X-axis is the angle change of rotation of the first driving member 31 or the second driving member 32, the Y-axis is the compression degree change of the first torsion spring 61 and the second torsion spring 62, and the change from the positive semi-axis to the negative semi-axis is the compression degree change of the first torsion spring 61, and the change from the negative semi-axis to the positive semi-axis is the compression degree change of the second torsion spring 62), in normal state, the first driving member 31 compresses the first torsion spring 61, and the first torsion spring 61 presses the first valve 21 against the first limiting member 41, the second driving member 32 compresses the second torsion spring 62, and the second torsion spring 62 presses the second valve 22 against the first sealing strip 511 and the second sealing strip 512. When unloading dust, rotate the first driving member 31 or the second driving member 32 to reduce the compression degree of the first torsion spring 61 and the second torsion spring 62. Since the stiffness coefficient of the first torsion spring 61 is greater than the stiffness coefficient of the second torsion spring 62, when rotating at the same angle, the first torsion spring 61 will reach the critical point first (the torsion spring is in a non-twisted state), while the second torsion spring 62 still maintains a certain compression state, so that the second valve 22 is pressed against the first sealing strip 511 and the second sealing strip 512.

[0042] Then, the first driving member 31 or the second driving member 32 is continuously rotated, and the first torsion spring 61, due to the existence of the load first valve 21, is reversely compressed to a certain extent, and then drives the first valve 21 to rotate until the first valve 21 is closed. When the first valve 21 is closed, the second torsion spring 62 reaches a critical point (the torsion spring is in a non-twisted state).

[0043] Subsequently, the first driving member 31 or the second driving member 32 is continuously rotated, and the first torsion spring 61 continues to be compressed in the reverse direction, so that the first valve 21 will remain in the closed state and gradually press against the first sealing strip 511 and the second sealing strip 512. The second torsion spring 62 will drive the second valve 22 to rotate after being compressed in the reverse direction to a certain extent due to the presence of the load on the second valve 22, until the second valve 22 is opened.

[0044] Finally, the first driving member 31 or the second driving member 32 is rotated in the reverse direction to restore the first valve 21 and the second valve 22 to the normal state. In this process, since the compression degree of the second torsion spring 62 is small and the compression degree of the first torsion spring 61 is large, when resetting, the second valve 22 can be reset to the closed state before the first valve 21 is opened.

[0045] Through the cooperation of the first torsion spring 61, the second torsion spring 62, the first stopper 41 and the second sealing member 52, when the cyclone dust collector is working, the first valve 21 can be opened and the second valve 22 can be closed, so that the dust can be smoothly collected in the dust discharge pipe 15. When the first driving member 31 or the second driving member 32 is rotated to discharge dust, the first valve 21 can be closed before the second valve 22 is opened, effectively ensuring the sealing of the dust discharge pipe 15 during dust discharge.

[0046] In this embodiment, the first driving member 31 and the second driving member 32 are both provided with a mounting tube 33, the first valve 21 and the second valve 22 are both provided with a column 23, the first torsion spring 61 and the second torsion spring 62 are respectively provided in the corresponding mounting tube 33, and the first torsion spring 61 and the second torsion spring 62 are respectively sleeved on the corresponding column 23, one end of the first torsion spring 61 and one end of the second torsion spring 62 are respectively fixedly connected to the corresponding mounting tube 33, and the other end is respectively fixedly connected to the corresponding column 23. The transmission between the first torsion spring 61 and the first driving member 31 and the first valve 21 is realized, and the transmission between the second torsion spring 62 and the second driving member 32 and the second valve 22 is realized.

[0047] In this embodiment, a limit block 7 is provided between the first driving member 31 and the second driving member 32, and the limit block 7 is used to prevent the first driving member 31 and the second driving member 32 from rotating relative to each other, so as to prevent the first torsion spring 61 and the second torsion spring 62 from driving the first driving member 31 and the second driving member 32 to rotate under the action of their own torque in a normal state. It should be noted that if the first driving member 31 or the second driving member 32 is driven by a motor with a locking function, the limit block 7 does not need to be provided.

[0048] In this embodiment, the first driving member 31 and the second driving member 32 are both provided with a through hole 34, the column 23 is inserted into the through hole 34, and an indicator bar 231 is provided on the column 23. By providing the through hole 34 and the indicator bar 231, the operator can judge the tilt state of the first valve 21 and the second valve 22 by observing the state of the indicator bar 231. In addition, the first driving member 31 and the second driving member 32 are both provided with a rotation bar 35, which is convenient for the operator to rotate the first driving member 31 or the second driving member 32.

[0049] The method of using the utility model is as follows:

[0050] When there is no need to remove dust from the dust removal pipe 15 , the first torsion spring 61 causes the first valve 21 to abut against the first limit member 41 , and the second torsion spring 62 causes the second valve 22 to abut against the corresponding first sealing strip 511 and second sealing strip 512 at the same time. In this state, dust is collected in the dust removal pipe 15 .

[0051] When the dust removal pipe 15 needs to be dusted, the first driving member 31 or the second driving member 32 is rotated by the rotating bar to drive the first valve 21 to rotate closed and the second valve 22 to rotate open. During this process, since the stiffness of the first torsion spring 61 is greater than the stiffness of the second torsion spring 62, the first valve 21 can be closed before the second valve 22 is opened, thereby sealing the dust removal pipe 15 in advance and effectively ensuring the sealing of the dust removal pipe 15 during dust removal.

[0052] After the dust removal is completed, the first driving member 31 or the second driving member 32 is rotated in the reverse direction to reset the first valve 21 and the second valve 22 , and the reset speed of the second valve 22 is faster than the reset speed of the first valve 21 .

[0053] The above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model. The technology, shape, and structure that are not described in detail in the utility model are all well-known technologies.
