However, it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, rather than limiting the claims of the present invention.

The same or similar existing technical means and some technical features of the embodiments are interchangeable and fall within the scope of the description and protection of the present invention.

[0033] The utility model discloses a filtering device. Figure 1This is a structural diagram of the filter screen die head in one embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of the filter device in one embodiment of the present invention; please refer to Figure 1 、 Figure 2 The filter device includes a filter body; the filter body is provided with a filter cavity, and a first filter die head 4 and a second filter die head are respectively provided at both ends of the filter cavity. The structure of the second filter die head is the same as or similar to that of the first filter die head 4, and the structure of the first filter die head 4 can be referred to.

[0034] The first filter die head 4 is provided with a first filter 1, a first honeycomb panel 3 and a first fixed mesh sleeve 2. The first filter 1 and the first honeycomb panel 3 are respectively fixed to the first filter die head 4 via the first fixed mesh sleeve 2. The second filter die head is provided with a second filter, a second honeycomb panel and a second fixed mesh sleeve. The second filter and the second honeycomb panel are respectively fixed to the second filter die head via the second fixed mesh sleeve.

[0035] Figure 3 This is a schematic diagram of the working principle of the filtering device in one embodiment of the present invention. Figure 4 This is a schematic diagram of the composition of the control part of the filter device in one embodiment of the present invention; please refer to Figure 3 、 Figure 4 The filtering device further includes a clamping mechanism and a main control circuit 10. The clamping mechanism is provided based on the first filter screen die 4 and / or the second filter screen die, and the clamping mechanism can be a clamping body 5. Of course, the clamping mechanism can also have other structures. In one embodiment, the clamping mechanism can include at least one clamping unit, which includes a connecting member 6, a rotation drive mechanism 7, and a clamping arm 8. Figure 3 The left picture shows that the clamping mechanism is in the state of clamping the filter die head. Figure 3 The right picture shows that the clamping mechanism is in the state of not clamping the filter die head.

[0036] The connector 6 is used to support the rotation drive mechanism 7. In one embodiment, the filter body 9 can be provided with a fixing mechanism to attach the connector 6 of the clamping unit to the filter body. The rotation drive mechanism 7 is provided on the connector 6. The rotation drive mechanism 7 is connected to the clamping arm 8 and can drive the clamping arm 8 to rotate, so that the clamping unit can clamp the honeycomb panel and fixed mesh sleeve to the corresponding filter die in a first state, and disengage the honeycomb panel and fixed mesh sleeve in a second state to facilitate removal.

[0037] The output end of the main control circuit 10 is connected to the input end of the rotation drive mechanism 7 and can send a control signal to the rotation drive mechanism 7 to control its operation.

[0038] In one embodiment of the present invention, the clamping mechanism includes at least two clamping units, each of which is evenly distributed on the side of the filter body, and each of which is capable of clamping a corresponding honeycomb panel and a fixed mesh to secure the honeycomb panel. In one embodiment, the clamping mechanism may include at least four clamping units, at least two of which are used to clamp the first honeycomb panel and the first fixed mesh, and at least two of which are used to clamp the second honeycomb panel and the second fixed mesh.

[0039] The clamping arm 8 rotates about a set rotation axis, and the rotation axis is provided with an angle sensor 11. The angle sensor 11 is used to sense the rotation angle data of the clamping arm 8. The output end of the angle sensor 11 is connected to the input end of the main control circuit 10, and can send the sensed rotation angle data to the main control circuit 10. Of course, the clamping arm 8 can also be provided with an angular velocity sensor, which is used to sense the rotational angular velocity of the clamping arm 8, thereby preventing the clamping arm 8 from rotating too quickly.

[0040] The clamping unit further includes a base fixed to the filter device body and a second rotation drive mechanism. The second rotation drive mechanism is disposed on the base and connected to the connector to drive the connector to rotate, thereby positioning the clamping arms of the connector close to the first honeycomb panel in a first position and close to the second honeycomb panel in a second position.

[0041] The filter body is provided with at least one first groove and at least one second groove at a setting position, and a locking mechanism is provided at the bottom of the connector. When the connector is in a first position, the locking mechanism can be positioned in the corresponding first groove, thereby maintaining the clamping unit in a relatively stable state; when the connector is in a second position, the locking mechanism can be positioned in the corresponding second groove, thereby maintaining the clamping unit in a relatively stable state.

[0042] The clamping arm is provided with a pressure sensor. When the clamping arm clamps a set honeycomb panel, the pressure sensor can sense the pressure data of the set area; the output end of the pressure sensor is connected to the input end of the main control circuit and can send the sensed pressure data to the main control circuit.

[0043] The clamping mechanism grips the honeycomb panel corresponding to the filter to be replaced, ensuring that the panel remains connected to the filter body and does not fall off. The clamping mechanism can be an automated actuator capable of being controlled to assume various positions, including a locked state, an open clamping arm state, and a relaxed state. Multiple clamping arms can be provided, each driven by a motor, pneumatic cylinder, or hydraulic cylinder. The clamping mechanism can automatically switch the clamped honeycomb panel in response to a control signal. This automatic switching can be achieved by providing a rotary motor to rotate the panel, thereby switching the clamping position.

[0044] In summary, the filtering device proposed in the present invention can ensure that the position of the honeycomb panel is stable during the replacement of the filter screen and is not easy to fall off, thereby improving the replacement work efficiency.
