Description

Technical Field

[0001] This utility model relates to the field of fire-fighting flue technology, and in particular to a fire-fighting flue structure that is easy to clean. Background Technology

[0002] Existing technology, such as Chinese utility model patent document, publication number CN219764806U, discloses a smoke exhaust device for fire protection engineering, including a smoke exhaust duct. The upper surface of the smoke exhaust duct is provided with an installation groove, and a filter assembly is inserted into the installation groove. Dust exhaust ports are provided on the lower surface of the smoke exhaust duct on both sides of the filter assembly. A movable plate is provided above the dust exhaust ports. A folded cloth is provided on the side of the movable plate away from the filter assembly. The folded cloth is connected to the lower inner wall of the smoke exhaust duct. A cleaning component that fits against the filter assembly is installed on the lower surface of the movable plate.

[0003] Based on the above, in the existing technology, a mounting groove is provided on the upper surface for inserting and installing filter components, while a dust discharge port is provided on the lower surface to cooperate with the dust collection box for dust collection. This design with openings at both the top and bottom is prone to air leakage, causing smoke and dust particles to be discharged outwards, and further improvements are needed. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a fire flue structure that reduces pipe openings and facilitates cleaning.

[0005] A fire flue structure designed for this purpose that is easy to clean includes connecting pipes that are interconnected with the flue pipes. The connecting pipes include interconnected connection pipes and cleaning pipes, which are arranged in a T-shape.

[0006] The front and rear ends of the connecting pipe are used to connect with the flue pipe;

[0007] The cleaning pipe is connected to the connecting pipe and extends downward. The lower end of the cleaning pipe is open. The lower end of the cleaning pipe is detachably connected to a base. The base is provided with an upwardly extending protruding ring. An accommodating space with an upper opening is formed inside the protruding ring.

[0008] An upwardly extending filter element is installed on the base, and the filter element is in contact with the inner wall of the connecting pipe and the inner wall of the cleaning pipe.

[0009] Preferably, the left and right sides of the convex ring are provided with limit slots, and the filter element is movably inserted into the limit slots.

[0010] Preferably, the upper surface of the base is provided with a positioning groove, which is in communication with the limiting slot.

[0013] Preferably, a locking fitting is rotatably provided on the outer side of the cleaning fitting, and a locking protrusion abutting against the lower surface of the base is provided on the lower side of the locking fitting.

[0014] The base is provided with clearance grooves that correspond to the locking protrusions;

[0015] When the clearance notch and the locking protrusion are aligned vertically, the base can move downwards, allowing the locking protrusion to pass through the clearance notch from bottom to top.

[0016] Preferably, the outer wall of the cleaning pipe is provided with an annular groove, and the locking pipe is provided with a plurality of limiting bolts that are movably inserted into the annular groove.

[0017] Preferably, a visualization window is provided on the outer wall of the cleaning pipe fitting.

[0018] Compared with the prior art, this invention features a cleaning pipe that connects to and extends downwards from the connecting pipe. The cleaning pipe has an opening at its lower end, and a base is detachably connected to its lower end. The base has an upwardly extending protruding ring, forming a receiving space with an upper opening within the protruding ring. An upwardly extending filter element is mounted on the base, and the filter element fits snugly against the inner walls of both the connecting pipe and the cleaning pipe. This invention secures the filter element to the base, while the receiving space formed by the base and the protruding ring collects dust and impurities falling from the filter element.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1-7 A fire-fighting flue structure that is easy to clean includes a connecting pipe 20 that is interconnected with a flue 10. The connecting pipe 20 includes a connecting fitting 210 and a cleaning fitting 220 that are interconnected and arranged in a T-shape. The front and rear ends of the connecting fitting 210 are used to connect with the flue 10. The cleaning fitting 220 is connected to the connecting fitting 210 and extends downward. The lower end of the cleaning fitting 220 is open. The lower end of the cleaning fitting 220 is detachably connected to a base 310. The base 310 is provided with an upwardly extending protruding ring 320, and the protruding ring 320 forms a receiving space 301 with an upper opening. An upwardly extending filter element 330 is installed on the base 310, and the filter element 330 is in contact with the inner wall of the connecting fitting 210 and the inner wall of the cleaning fitting 220.

[0028] This invention allows the filter element to be fixed in place by a base, while the space formed by the base and the convex ring can be used to collect dust and impurities that fall from the filter element. During maintenance, the filter element can be removed simply by disassembling the base, reducing the number of openings and improving sealing.

[0029] During cleaning and maintenance, the base 310 and the cleaning fitting 220 can be disassembled and separated, and the base 310 can be taken out downwards. At the same time, the filter element 330 can be moved downwards simultaneously.

[0030] See Figure 2 and Figure 5 The convex ring 320 is provided with limiting slots 321 on both the left and right sides. The filter element 330 is movably inserted into the limiting slots 321, which can effectively constrain the position of the filter element 330 to avoid displacement of the filter element 330 due to air flow.

[0031] See Figure 2 and Figure 5The upper surface of the base 310 is provided with a positioning groove 312, which is in communication with the limiting slot 321; the lower end of the filter element 330 is movably inserted into the positioning groove 312. The positioning groove 312 can further constrain the position of the filter element 330 to ensure the position of the filter element 330 and prevent its displacement during use.

[0032] See Figure 5 The cleaning pipe fitting 220 has positioning slots 222 on its left and right inner walls, and the filter element 330 is movably inserted into the positioning slots 222 on its left and right sides.

[0033] See Figure 6 A locking fitting 40 is rotatably provided on the outer side of the cleaning fitting 220. A locking protrusion 410 is provided on the lower side of the locking fitting 40, which abuts against the lower surface of the base 310. An avoidance groove 311 corresponding to the locking protrusion 410 is provided on the base 310.

[0034] Under the action of the rotating locking fitting 40, when the locking protrusion 410 and the clearance notch 311 are misaligned, the base 310 cannot move downwards, thus locking. When it is necessary to unlock and disassemble the base 310, the locking fitting 40 is rotated so that the clearance notch 311 and the locking protrusion 410 are aligned vertically. At this time, the base 310 can move downwards, allowing the locking protrusion 410 to pass through the clearance notch 311 from bottom to top, thus unlocking and disassembling.

[0035] See Figure 3 The outer wall of the cleaning pipe fitting 220 is provided with an annular groove 221, and the locking pipe fitting 40 is provided with multiple limiting bolts 50 that are movably inserted into the annular groove 221. When the locking pipe fitting 40 rotates relative to the cleaning pipe fitting 220, the limiting bolts 50 rotate with the locking pipe fitting 40 within the annular groove 221.

[0036] In this invention, a visualization window 60 is provided on the outer wall of the cleaning fitting 220. This allows maintenance personnel to quickly observe the condition of the internal filter element 330 and determine whether cleaning is required.

[0037] In this utility model, a grip handle 300 is provided on the lower surface of the base 310.
