DETAILED DESCRIPTION

[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative labor fall within the scope of the present application.

[0023] As shown in Figure 1 and Figure 2 A double purification oil fume purification equipment, comprising: flue 1, two filter mechanisms are sequentially arranged in the flue 1.

[0024] As shown in Figure 3 and Figure 4 The filter mechanism comprises a filter screen 2 and a filter screen mounting frame 3. The internal passage of the flue 1 is rectangular, and the filter screen 2 is adapted to the internal passage of the flue 1 and is also rectangular.

[0025] The filter screen 2 is detachably arranged in the filter screen mounting frame 3. Specifically, the filter screen mounting frame 3 is rectangular, a center opening adapted to the filter screen 2 is arranged in the filter screen mounting frame 3, and a ring of stop rings 13 is arranged at the bottom of the opening. The filter screen 2 is installed in the filter screen mounting frame 3 by sinking from the top of the opening.

[0026] The filter screen mounting frame 3 is slidingly arranged in the mounting slide recessed in the side of the flue 1, and the first end thereof corresponds to the mounting slide port.

[0027] As shown in Figure 3 The first end of the filter screen mounting frame 3 is provided with a downwardly recessed pulling groove 4 from the top surface, so as to facilitate the pulling of the filter screen mounting frame 3 by the staff. The filter screen mounting frame 3 is provided with sliding grooves 5 on both sides, and the sliding grooves 5 extend from the first end to the second end of the filter screen mounting frame 3. A sliding seat 6 is slidingly arranged in the sliding groove 5, and a connecting rod 7 is hingedly connected to the sliding seat 6.

[0028] As shown in Figure 5 A closable door 8 is arranged at the mounting slide port. The bottom of the door 8 is rotatably connected to the flue 1, the top is provided with a limiting plate 9, and the outer side is provided with a handle 10. The other end of the connecting rod 7 is hingedly connected to the inner wall of the door 8, and the hinged position is close to the top end of the door 8. Specifically, a connecting protrusion 14 is arranged on the inner wall of the door 8, and the end of the connecting rod 7 is hingedly connected to the connecting protrusion 14. When the door 8 is closed, the sliding seat 6 is located at the first end of the sliding groove 5.

[0029] Preferably, a rounded corner is arranged at the bottom edge of the end of the first end of the filter screen mounting frame 3, so as to avoid interference when the door 8 is opened and closed and the filter screen mounting frame 3 is sliding.

[0030] As shown in Figure 6As shown, the flue 1 is provided with a slide plate 11 above the sealing door 8, the slide plate 11 is corresponding to the limiting plate 9, the slide plate 11 can fix the limiting plate 9, and the position of the sealing door 8 is limited.

[0031] The slide plate 11 is provided with a side protrusion 12, and the side protrusion 12 is provided with a spring 16. The top end of the spring 16 is fixedly connected with the flue 1, and the bottom end is fixedly connected with the side protrusion 12, so as to keep the slide plate 11 having a downward moving trend, that is, the slide plate 11 is kept at the bottom end of the slideable range. The outer wall of the slide plate 11 is provided with a plurality of anti-skid protrusions 15, so as to prevent the slide plate 11 from slipping when being pushed upward by the worker.

[0032] Working process: when the filter screen 2 needs to be cleaned or replaced, the slide plate 11 is first pushed upward, so that the limiting plate 9 is separated from the locking of the slide plate 11, and then the sealing door 8 is opened through the pull handle 10; when the sealing door 8 is opened and rotated, the slide seat 6 is driven to move outwardly through the connecting rod 7, the slide seat 6 drives the filter screen mounting frame 3 to move outwardly synchronously, so that the first end of the filter screen mounting frame 3 is exposed to the installation slide, the worker pulls the recess 4 to drive the filter screen mounting frame 3 to further slide out of the installation slide, until the filter screen 2 is completely exposed, after the filter screen 2 is replaced, the filter screen mounting frame 3 is pushed back to the installation slide, and the sealing door 8 is closed.

[0033] The above describes the preferred embodiment of the present application in detail. It should be understood that those skilled in the art can make many modifications and changes without creative labor according to the concept of the present application. Therefore, any technical solution obtained by logical analysis, reasoning or limited experiment on the basis of the prior art according to the concept of the present application should be within the protection scope defined by the claims.
