[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] like Figure 1 and Figure 2 As shown in the embodiment of this utility model, the modular filter bag includes a mounting plate 1 for fixing the filter bag assembly;

[0023] Filter bag 2 is installed on mounting plate 1;

[0024] The top plate 3 is connected to the mounting plate 1 via a disassembly and assembly mechanism.

[0025] The disassembly and assembly mechanism includes a limiting groove 4 opened on the side wall of the top plate 3. An elastic element 5 is provided in the limiting groove 4. The outer side of the elastic element 5 is connected to a movable inner rod 6. The outer side of the movable inner rod 6 is fixed to the side pull plate 9. A plug-in rod 11 is provided on the side of the inner wall of the side pull plate 9 away from the movable inner rod 6. The plug-in rod 11 is plugged into the side wall of the mounting plate 1.

[0026] Pull the side plate 9 outwards, compress the elastic element 5, and disengage the plug rod 11 from the mounting plate 1; after removing the top plate 3, directly replace the filter bag 2, and reinstall by reversing the operation.

[0027] The fixing rods 12 are symmetrically installed at the bottom of the top plate 3 and inserted into the mounting plate 1 to form a preliminary limit;

[0028] The guide plate 13 is installed at the bottom of the outer wall of the side pull plate 9. Its length is longer than the plug rod 11, and the top of the inner side of the guide plate 13 is designed to be inclined.

[0029] The filter bag 2 is fixed to the mounting plate 1, and the top plate 3 is initially inserted into the bottom of the mounting plate 1 through the fixing rod 12; the side pull plate 9 is pressed, the elastic element 5 is compressed and shrinks, which drives the insertion rod 11 to move outward. At this time, the inclined end face of the guide plate 13 abuts against the edge of the mounting plate 1; the top plate 3 is pushed along the guide plate 13, and the insertion rod 11 is automatically inserted into the hole on the side wall of the mounting plate 1 under the action of the restoring force of the elastic element 5, thus completing the locking.

[0030] The inner wall of the limiting groove 4 is symmetrically provided with slide rails 8, and a slider 7 is slidably connected in the slide rails 8. The slider 7 is fixed on the outer wall of the movable inner rod 6.

[0031] A protective pad 10 is adhered to the inner wall of the side pull plate 9, and the inner side of the protective pad 10 abuts against the contact surface of the mounting plate 1 and the top plate 3.

[0032] The elastic element 5 is a spring or elastic rubber strip, used to provide the restoring force of the side pull plate 9.

[0033] The guide plate 13 has an inclination angle of 30°-60° and is used to guide the insertion operation of the plug-in rod 11 and the mounting plate 1.

[0034] Working principle:

[0035] Filtration stage: Dust-laden gas is discharged after being filtered through multiple layers of filter bags 2, while clean gas is discharged through the outlet of the top plate 3;

[0036] Disassembly and assembly mechanism: When the side pull plate 9 is pulled by an external force, the movable inner rod 6 slides along the slide rail 8, causing the plug rod 11 to disengage from the mounting plate 1, thus releasing the lock between the top plate 3 and the mounting plate 1;

[0037] Reset guide: The elastic element 5 automatically resets after disassembly, and the inclined surface of the guide plate 13 guides the plug rod 11 to be accurately inserted into the mounting plate 1.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
