[0024] Reference Figs. 1 to 3 The embodiment of the present application provides a kind of purification furnace air inlet cylinder extraction device, including cylinder 10, rotating rod 20 and wedge block 30.

[0025] Wherein the cylinder 10 in axial one end, i.e. bottom end, is equipped with cooperation block 11, simultaneously cooperation block 11 is in radial protrusion cylinder 10, in addition, the side of cooperation block 11 away from cylinder 10 is equipped with first slope structure 111, wherein the slope of first slope structure 111 extends along the axial direction of cylinder 10.Cylinder cavity 101 of cylinder 10 extends to first slope structure 111 along the axial direction.

[0026] The rotating rod 20 is located in the barrel cavity 101 and is provided with external threads, and the rotating rod 20 and the side wall of the barrel cavity 101 are kept with a predetermined gap, preferably, the gap between the rotating rod 20 and the barrel cavity 101 is 7-10 mm, the matching gap mainly provides a shift space for the wedge block 30, so that the wedge block 30 can move in a certain radial range, and is clamped against or away from the inner wall of the air inlet cylinder 40, and also forms a certain limit for the wedge block 30, so as to avoid damaging the air inlet cylinder 40 due to excessive radial movement distance. The end of the rotating rod 20 away from the matching block 11, i.e. the top end, protrudes from the barrel 10, and is provided with a rotating part 21 at the end, and the rotating part 21 protrudes from the barrel cavity 101 in the radial direction. On the one hand, the rotating part 21 can limit the rotating rod 20, so as to avoid the rotating rod 20 from falling out of the barrel cavity 101 directly, and on the other hand, the rotating part 21 can also facilitate the rotating operation of the staff.

[0027] The wedge block 30 is provided with a second slope surface structure 31 which is in sliding cooperation with the first slope surface structure 111, and the wedge block 30 is provided with an internal thread passage which is in cooperation with the external threads at the central axis, so that when the rotating rod 20 is oriented to rotate, based on the thread cooperation relationship between the external threads and the internal thread passage and the sliding cooperation relationship between the first slope surface structure 111 and the second slope surface structure 31, the wedge block 30 can be oriented to slide and form external support relative to the matching block 11.

[0028] In order to facilitate manufacturing and save raw materials, the rotating rod 20 is only provided with the external threads at one end close to the matching block 11, and only needs to satisfy the thread cooperation relationship with the internal thread passage.

[0029] The working process of the tool is roughly as follows: the barrel 10, the matching block 11 and the wedge block 30 of the tool are inserted into the air inlet barrel 40, then the rotating part 21 is rotated clockwise, the wedge block 30 is slid along the first slope structure 111 under the thread cooperation and sliding cooperation, during the sliding of the wedge block 30, the rotating rod 20 and the wedge block 30 are synchronously moved outward due to the gap between the rotating rod 20 and the side wall of the barrel cavity 101, and then the barrel 10 is forced to be offset in the air inlet barrel 40 to a certain extent, until the bottom end of the outer side of the wedge block 30 (i.e. the side far away from the second slope structure) and the top end of the outer side of the matching block 11 are simultaneously abutted against the inner side wall of the air inlet barrel 40, that is, are tightly supported on the inner side wall of the air inlet barrel 40, at this time, the next operation can be performed, and the air inlet barrel 40 can be taken out. If the rotating part 21 is rotated counterclockwise, the wedge block 30 will slide downward along the first slope structure 111, at this time, the bottom end of the wedge block 30 is gradually abutted against the inner side wall of the air inlet barrel 40, and the top end of the matching block 11 on the side of the first slope structure 111 is gradually abutted against the inner side wall of the air inlet barrel 40, and a clamping effect of the inner hole can also be formed, and the air inlet barrel 40 can be further taken out.

[0030] In one embodiment, the barrel 10 is provided with a handle 12 at the end far away from the matching block 11, so that the worker holds the barrel 10 by one hand and rotates the rotating part 21 by the other hand, which is convenient for operation.

[0031] Further preferably, the handle 12 is a round handle or a vertical symmetric protruding one-word handle of the barrel 10.

[0032] In one embodiment, the rotating part 21 comprises a round knob 211 and a connecting sleeve 212 coaxially connected on one side of the round knob 211, wherein the outer diameter of the connecting sleeve 212 is greater than the inner diameter of the barrel cavity 101, and the rotating rod 20 is coaxially connected in the connecting sleeve 212, so that the rotating rod 20 is conveniently rotated by the round knob 211 and is limited by the connecting sleeve 212, avoiding the jumping out of the barrel cavity 101. Generally, the diameter of the round knob 211 is greater than the diameter of the connecting sleeve 212.

[0033] In one embodiment, the outer side of the wedge block 30 and the outer side of the matching block 11 are provided with anti-skid structures to enhance the friction between them and the inner side wall of the air inlet barrel.

[0034] Further preferably, the matching block 11 and the wedge block 30 are both nut structures, and the anti-skid structure is an outer thread integrally arranged on the outer surface of the nut structure, so that the matching block 11 and the wedge block 30 can be directly formed by the existing nut manufacturing process, saving raw materials and reducing costs.

[0035] In one embodiment, the internal threaded channel is a single-side open channel, and the internal threaded channel is closed at one end away from the engaging block, so that the rotation amount of the rotating rod 20, i.e. the offset amount of the wedge block 30, can be limited by limiting the depth of the internal threaded channel, avoiding damage to the inner side wall of the air inlet cylinder 40 due to excessive rotation, which is similar to the effect of the gap between the rotating rod 20 and the side wall of the cylinder cavity 101, and the operation is safer.

[0036] It should be noted that the terms "first", "second" in the present application are only for descriptive purposes, and do not indicate any order, and cannot be understood as indicating or implying relative importance, and these terms can be interpreted as names.

[0037] Those skilled in the art will understand that the embodiments of the utility model shown in the above description and the drawings are only examples and do not limit the utility model.
