DETAILED DESCRIPTION

[0027] The present invention will be described more clearly and completely below by way of a preferred embodiment in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiment.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a baffle connection and fixing structure includes a tubular shell 1 and a plurality of baffles, each baffle including a baffle ring 2. Since the baffle rod structure is fixedly mounted on the baffle ring 2, the position of the baffle rod is indirectly adjusted while adjusting the position of the baffle ring 2. The connection and fixation of the baffles focuses on the connection and fixation of the baffle ring 2. Therefore, the structural diagram of the baffle rod part is omitted in the accompanying drawings of the present utility model. The inner wall of the tubular shell 1 is provided with a plurality of clamping grooves 11 at equal intervals along the circumferential direction. The number of the clamping grooves 11 can be adjusted according to the size of the tubular shell 1 of the heat exchanger and the size of the baffle. A base 3 is slidably clamped on each clamping groove 11, a cavity is provided inside the base 3, and a plurality of elastic adjustment mechanisms 5 are sequentially installed in the cavity. A clamp 4 is installed on each elastic adjustment mechanism 5. The clamp 4 is clamped on the baffle ring 2, and the clamp 4 adjusts the clamping degree with the baffle ring 2 through the elastic adjustment mechanism 5. Example

[0029] like Figure 2 As shown, the clamp 4 includes two oppositely arranged clamps 41, one end of each clamp 41 located outside the cavity of the base 3 is clamped on the deflector ring 2 and is flush with the inner wall surface of the deflector ring 2, and the other end located inside the cavity of the base 3 is connected to the elastic adjustment mechanism 5, and the two clamps 41 are symmetrically arranged about the deflector ring 2.

[0030] Each of the elastic adjustment mechanisms 5 includes two sliding blocks 51 correspondingly connected to the two clamps 41 and two clamp width adjustment components 52 correspondingly connected to the two sliding blocks 51. The clamp width adjustment components 52 are used to adjust the distance between the two clamps 41 according to the wall width of the baffle ring 2.

[0031] like Figure 5 As shown, the clamp width adjustment assembly 52 includes a fixed column 521, a sleeve 522, a sliding column 523 and a telescopic spring 524. The fixed column 521 is fixed in the cavity of the base 3, the sleeve 522 is fixedly connected to the side of the fixed column 521 close to the sliding block 51, the telescopic spring 524 is arranged in the sleeve 522 and one end is connected to the inner wall of the bottom of the sleeve 522, the other end of the telescopic spring 524 is connected to the sliding column 523, the sliding column 523 is movably connected to the sleeve 522, and the other end of the sliding column 523 is fixedly connected to the sliding block 51.

[0032] When the deflector ring 2 is clamped onto the clamp 4, if the width between the two clamps 41 is smaller than the wall width of the deflector ring 2, the two clamps 41 are pushed to both sides, and the sliding blocks 51 connected at the lower ends of the two clamps 41 slide in the cavity of the base 3, and at the same time drive the sliding column 523 to slide in the sleeve 522, and then squeeze the telescopic spring 524 to adjust the width between the two clamps 41, and then clamp the deflector ring 2. At this time, the telescopic spring 524 is in a compressed state, and there will be a force acting on the sliding column 523, thereby ensuring that the clamp 4 can firmly clamp the deflector ring 2. Example

[0033] like Figure 6 , Figure 7 and Fig. 9 As shown, the two clamps 41 are in an inverted L-shape, and one end of the inverted L-shaped clamp 41 is bent and clamped on the baffle ring 2. Setting the shape of the clamp 41 to an inverted L-shape can better clamp the baffle ring 2.

[0034] like Figure 8 As shown, a slideway is provided inside the sliding block 51, and an inverted L-shaped clamping plate 41 is movably connected to the slideway. A telescopic spring 2 511 is provided in the slideway, and one end of the telescopic spring 2 511 is connected to the inner wall of the bottom of the slideway, and the other end is connected to the inverted L-shaped clamping plate 41.

[0035] When the deflector ring 2 is placed on the clamp 4, if the height between the two inverted L-shaped clamps 41 of the clamp 4 and the base 3 is less than the wall thickness of the deflector ring 2, the two inverted L-shaped clamps 41 are pulled upward. At this time, the inverted L-shaped clamps slide in the slideway in the sliding block 51, and at the same time drive the telescopic spring 2 511 to be in a stretched state. When the distance between the inverted L-shaped clamps 41 and the base 3 is sufficient to allow the deflector ring 2 to be clamped between the inverted L-shaped clamps 41 when the deflector ring 2 is placed in, and the bent part of the inverted L-shaped clamps 41 is buckled on the inner wall of the deflector ring 2. At this time, the telescopic spring 2 511 is always in a stretched state, which will pull the clamp 4 downward to firmly clamp the deflector ring 2.

[0036] The working principle of the utility model is as follows: first, the deflector ring 2 of the deflector grid is fixed to the clamping connection device by the clamp 4. During the connection process, the two inverted L-shaped clamps 41 of the clamp 4 can be adjusted according to the wall width and wall thickness of the deflector ring 2. The distance between the two inverted L-shaped clamps 41 can be changed by moving to the left and right sides, and the distance between the two inverted L-shaped clamps 41 and the base 3 can be changed by adjusting up and down, so that the deflector ring 2 can be firmly fixed on the clamping connection device, and multiple deflector grids are fixed to the base 3 in turn. At this time, the deflector grid and the clamp 4 can be welded firmly by spot welding. Even if the welding of this device is loose, the deflector grid will not fall off due to the fixation of the clamp 4. After fixation, the base 3 is clamped into the clamping groove 11 of the tubular shell 1, so that the deflector grid can be smoothly installed in the tubular shell 1.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
