Description

Technical Field

[0001] This utility model relates to the field of dust collector housing technology, specifically to a dust collector housing structure with strong sealing performance. Background Technology

[0002] The dust collector housing is an important component of the dust collector, effectively protecting the internal components and preventing dust-laden gas from leaking directly to the outside. Therefore, the dust collector housing needs to have strong sealing properties during use. For example, patent document CN218575255U discloses a noise-reducing housing for a laser cutting dust collector. This dust collector housing, through the setting of a support plate, guide plate, motor, guide rod, limiting rod, limiting plate, and top block, allows the filter cartridge to be placed on the support plate during use. After aligning the filter cartridge on the support plate with the hole on the main body, the filter cartridge is directly pushed into the main body, making installation more convenient, reducing manual handling, improving the efficiency of filter cartridge installation, and making it more convenient to use.

[0003] However, when the dust collector housing is connected to external filter cartridges and other components, flange connection is generally used. However, flange connection requires multiple connecting bolts for fixing. As the number of bolts increases, the disassembly and assembly time of the dust collector housing increases, reducing the ease of installation of the dust collector housing. Utility Model Content

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a dust collector shell structure with strong sealing performance.

[0026] This utility model provides, for example Figure 1-4 The diagram illustrates a dust collector housing structure with strong sealing performance, comprising a dust collector housing 1 and a connecting flange 2 fixedly disposed at the bottom of the dust collector housing 1. The connecting flange 2 has multiple axially evenly distributed connecting holes 3 inside, each connecting hole 3 having a slidably inserted positioning sleeve 4. The top of the positioning sleeve 4 has an internal threaded groove, and a drive screw 5 is threaded through it. Multiple axially evenly distributed mounting brackets 6 are fixedly disposed on the top of the connecting flange 2. The upper end of the drive screw 5 is rotatably disposed within the mounting bracket 6. The mounting bracket 6 is an L-shaped mounting bracket. A limiting block 1 is fixedly disposed on the outer wall of each positioning sleeve 4. 3. A limiting groove 14 is provided on the inner wall of the mounting bracket 6. The end of the limiting block 13 is slidably disposed in the limiting groove 14. The rod walls of multiple driving screws 5 are jointly provided with a synchronous driving mechanism for driving the positioning sleeve 4 to move. The synchronous driving mechanism includes a support ring 7. The support ring 7 is sleeved on the lower end of the outer wall of the dust collector housing 1 and fixedly disposed on the top of the connecting flange 2. An external gear ring 8 is rotatably sleeved on the outer wall of the support ring 7. A spur gear 9 is fixedly sleeved on the rod wall of the driving screw 5. An annular groove is provided on the outer wall of the support ring 7. The external gear ring 8 is rotatably disposed in the annular groove. The external gear ring 8 and the spur gear 9 are configured to cooperate.

[0027] In order to ensure that the positioning sleeve 4 can be inserted into the connection hole of the connecting flange of the adjacent component, so that the positioning sleeve 4 and the connecting flange can quickly engage and complete the clamping connection, such as... Figure 2-4As shown, the lower end of the positioning sleeve 4 is provided with a groove, and a connecting positioning mechanism for limiting the position of the positioning sleeve 4 is provided in the groove. The connecting positioning mechanism includes a wedge block 10, which is slidably disposed in the groove. Guide grooves are provided on both sides of the inner wall of the groove. A guide block 11 is fixedly inserted through the end of the wedge block 10. The end of the guide block 11 is slidably disposed in the guide groove. The longitudinal section of the guide block 11 and the guide groove are both rectangular. A guide spring 12 is fixedly disposed between the guide block 11 and the inner wall of the guide groove.

[0028] Instructions for use: When connecting the dust collector housing 1 to components such as filter cartridges, first align the connecting flange 2 at the bottom of the dust collector housing 1 with the flange of the component to be connected. Rotate the outer gear ring 8 on the outer wall of the support ring 7. The outer gear ring 8 rotates within the annular groove of the support ring 7. Because the outer gear ring 8 engages with the circular gear 9 on the wall of the drive screw 5, it will drive multiple drive screws 5 to rotate synchronously. The drive screws 5 rotate within the mounting bracket 6. Since the positioning sleeve 4 is threadedly connected to the drive screw 5, and the limiting block 13 on the outer wall of the positioning sleeve 4 slides within the limiting groove 14 of the mounting bracket 6, the rotation of the positioning sleeve 4 is restricted, allowing the drive screws 5 to rotate freely. During rotation, the positioning sleeve 4 slides downward along the connecting hole 3, and the lower end of the positioning sleeve 4 is inserted into the corresponding hole of the flange to be connected. During the process, the wedge block 10 is squeezed and compressed into the groove, and the guide block 11 slides along the guide groove and compresses the guide spring 12. When the positioning sleeve 4 is fully inserted, the guide spring 12 returns to its original position, pushes the wedge block 10 out of the groove, and clamps the flange to be connected, thus completing the positioning and fixing. This achieves a quick and sealed connection between the dust collector shell 1 and other components. Since it is a connection between adjacent connecting flanges, it can ensure the sealing performance between the dust collector shell 1 and other components, thereby improving the performance of the dust collector shell.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
