Specific implementation

[0026] Next, the utility model is described further in combination with the drawings and specific implementation, and it needs to be explained that, under the premise of not conflicting, the following described each embodiment or each technical feature between can be combined to form new embodiment. Embodiment

[0027] Please combine Figures 1-5The industrial dust collector with filter screen convenient to replace provided by the embodiment comprises a dust collector main body 1, a corrugated hose 2 fixedly connected to the top of the dust collector main body 1, a dust cover 3 fixedly connected to the bottom end of the corrugated hose 2, a plurality of mounting blocks 4 fixedly connected to the inner wall of the dust cover 3, a pre-positioning rod 5 inserted into the inside of the mounting block 4, a placing rack 6 fixedly connected to the bottom end of the pre-positioning rod 5, a filter screen body 7 arranged in the inside of the placing rack 6, an extension block 8 fixedly connected to the lower surface of the placing rack 6, a positioning mechanism 9 arranged on the surface of the extension block 8, an elongated through slot 10 formed on the surface of the dust cover 3, and a non-through slot 11 formed on the surface of the dust cover 3.

[0028] The positioning mechanism 9 comprises a first sleeve 901 fixedly connected to the surface of the extension block 8, a first reset spring 902 fixedly connected to the inner wall of the first sleeve 901, a second sleeve 903 fixedly connected to the surface of the first reset spring 902, a second reset spring 904 fixedly connected to the inner wall of the second sleeve 903, a supporting rod 905 fixedly connected to the surface of the second reset spring 904, and an embedded clamping block 906 rotatably connected to the surface of the supporting rod 905.

[0029] The embedded clamping block 906 is matched with the elongated through slot 10 and the non-through slot 11.

[0030] The first sleeve 901 and the second sleeve 903 are in contact with the lower surface of the placing rack 6.

[0031] The upper surface of the dust cover 3 is provided with a connecting hole 12 matched with the corrugated hose 2. Since the upper surface of the dust cover 3 is provided with the connecting hole 12 matched with the corrugated hose 2, the corrugated hose 2 can be stably connected to the dust cover 3, ensuring the normal dust suction function of the dust collector, so that the airflow in the dust suction process can smoothly pass through the corrugated hose 2 and the dust cover 3.

[0032] The lower surface of the dust collector main body 1 is fixedly connected with a bottom plate 13, and the four corners of the lower surface of the bottom plate 13 are fixedly connected with moving wheels 14. The bottom plate 13 fixedly connected to the lower surface of the dust collector main body 1 and the moving wheels 14 at the four corners of the lower surface of the bottom plate 13 enable the entire industrial dust collector to be conveniently moved, facilitating dust suction operation in different working areas.

[0033] The upper surface of the bottom plate 13 is fixedly connected with an auxiliary handle 15.

[0034] The implementation principle of the industrial dust collector with the filter screen convenient to replace in the embodiment of the application is as follows: when a person wants to replace the filter screen, the embedded clamping block 906 is first pulled, because the embedded clamping block 906 is connected with the second reset spring 904 through the supporting rod 905, so the second reset spring 904 is stretched when the embedded clamping block 906 is pulled, until the embedded clamping block 906 is separated from the non-through groove 11, then the embedded clamping block 906 is rotated to be in the same plane with the long-shaped through groove 10, and then the pulling force applied to the embedded clamping block 906 is cancelled, under the reset action of the first reset spring 902, the embedded clamping block 906 moves to the inside of the first sleeve 901 through the long-shaped through groove 10, so that the clamping structure formed by the embedded clamping block 906 and the dust collection cover 3 is cancelled, because the clamping structure is cancelled, the support of the first sleeve 901 and the second sleeve 903 to the placing rack 6 is cancelled, the placing rack 6 can be separated from the dust collection cover 3, the person takes out the filter screen body 7 in the inside of the placing rack 6, then the new filter screen body 7 is placed in the inside of the placing rack 6, then the person inserts the predetermined positioning rod 5 at the four corners of the upper surface of the placing rack 6, which is provided with the new filter screen body 7, into the mounting block 4 in the inner wall of the dust collection cover 3, and pre-positioning is performed, then the person pulls the second sleeve 903 through the first sleeve 901 on the surface of the extension block 8 fixedly connected to the lower surface of the placing rack 6, because the second sleeve 903 is connected with the first sleeve 901 through the first reset spring 902, when the second sleeve 903 moves to the surface of the long-shaped through groove 10, the supporting rod 905 and the embedded clamping block 906 on the surface of the second sleeve 903 enter the inside of the long-shaped through groove 10, when the supporting rod 905 and the embedded clamping block 906 complete the passing through the long-shaped through groove 10, the person rotates the embedded clamping block 906 on the surface of the supporting rod 905, so that the embedded clamping block 906 is in the same plane with the non-through groove 11, then the person cancels the pulling force applied to the embedded clamping block 906, the supporting rod 905 drives the embedded clamping block 906 to be clamped into the inside of the non-through groove 11 under the reset elastic action of the second reset spring 904, so that the clamping structure of the embedded clamping block 906 and the dust collection cover 3 is completed, when the clamping structure is completed, the first sleeve 901 and the second sleeve 903 support the lower surface of the placing rack 6, so that the stability of the mounting rack is ensured, the person holds the auxiliary handle 15 on the upper surface of the bottom plate 13, moves the entire industrial dust collector by pushing the auxiliary handle 15 through the moving wheel 14 at the four corners of the lower surface of the bottom plate 13, so that the dust collector can be moved to different working areas for dust collection operation.

[0035] The above embodiment is only a preferred embodiment of the present application, and cannot be used to limit the range of protection of the present application, and any non-substantial change and replacement made by a person skilled in the art on the basis of the present application belongs to the range of protection of the present application.
