Description

Technical Field

[0001] This invention relates to the field of baffle fixing equipment, and more particularly to a baffle fixing mechanism. Background Technology

[0002] In carbon black production, the air preheater is a key heat exchange device, and its installation quality directly affects heat exchange efficiency and production stability. The arrangement of the baffles plays a decisive role in the heat exchange effect of the air preheater. According to the technical requirements of carbon black production processes, the baffles in the air preheater must be arranged in a staggered manner to extend the flow path of the heat exchange medium and enhance the heat exchange effect. However, the baffles in existing air preheaters are generally designed with a semi-circular structure. During installation, this structural characteristic results in the baffles lacking stable support and positioning points, making them prone to tilting or sliding to one side, which brings significant inconvenience to installation and construction.

[0003] Currently, the installation of heat exchanger tubes and baffles involves first hoisting the heat exchanger tubes using a crane, then manually guiding them through pre-drilled holes in each baffle plate. The heat exchanger tubes temporarily fix the baffles in place, and the remaining baffles are then sequentially fitted onto the heat exchanger tubes and their positions adjusted. However, this installation method has significant drawbacks: firstly, the precise positioning of the heat exchanger tubes and baffles requires multiple operators, making the process cumbersome and labor-intensive, severely impacting installation efficiency; secondly, the problem of baffles tilting and sliding in a vertical position remains unresolved, and the temporarily fixed baffles are still prone to displacement. This makes it difficult to guarantee the accuracy of the staggered arrangement of the baffles, and the heat exchanger tubes are easily installed in incorrect holes on the baffles. This not only increases installation difficulty but may also affect the subsequent performance of the air preheater due to baffle position deviations, potentially causing equipment malfunctions and posing a potential risk to carbon black production. Summary of the Invention

[0004] To address the problems of cumbersome procedures, low installation efficiency, and difficulty in ensuring installation accuracy in the current method of temporarily fixing baffles using heat exchange tubes, this invention provides a baffle fixing mechanism.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A baffle plate fixing mechanism includes a frame, a first fixing component, a second fixing component, and a baffle plate. The first fixing component is disposed on one side of the top of the frame, and the second fixing component is disposed on the other side of the top of the frame. A limiting opening is formed on the baffle plate. The first fixing component includes a first support frame and a plate clamping block. The plate clamping block is fixed on the first support frame, and a first slot adapted to the baffle plate is formed on the plate clamping block. The second fixing component includes a second support frame and a limiting pin. The second support frame has a second slot adapted to the baffle plate, and the limiting pin is adapted to the limiting opening.

[0006] Furthermore, the first fixing component is connected to the frame via a sliding component, the sliding component including a slider with a convex cross-section and a slide rail with a concave cross-section.

[0007] Furthermore, the first support frame includes a slide plate, a support plate, and a baffle. The baffle is fixed vertically on the slide plate adjacent to one side of the second fixing component. One side of the support plate is fixedly connected to the baffle, and the other side is fixedly connected to the slide plate.

[0008] Furthermore, the plate clip is fixedly connected to the upper part of the baffle, and the cross-section of the first slot is V-shaped.

[0009] Furthermore, there are two second support frames arranged symmetrically, and the limiting pin is located between the two second support frames.

[0010] Furthermore, the limiting pin includes a housing, a pin head, and a spring. The bottom of the pin head is connected to a limiting plate, the limiting plate is disposed in the cavity of the housing, the spring is located between the limiting plate and the bottom of the housing, and the pin head is disposed in the limiting opening.

[0011] Furthermore, the second support frame includes a pair of base plates and a pair of connecting plates, the bottom of the base plates is connected to the top of the frame, the bottom of the connecting plates is connected to the top of the base plates, and the second slot is formed by the gap between the two base plates and the gap between the two connecting plates.

[0012] Furthermore, a semi-circular pad is provided inside the second slot.

[0013] Furthermore, the baffle plate is in the shape of an arc, and a plurality of mounting holes are provided on the baffle plate, and the limiting port is located at the bottom edge of the baffle plate.

[0014] Furthermore, U-shaped plates are fixed on both the left and right sides of the bottom of the frame, and several double-sided track wheels are rotatably connected inside the U-shaped plates, and several lifting rings are provided on the top of the U-shaped plates.

[0015] The beneficial effects of the present invention are as follows: The present invention, through the cooperation of the first fixing component and the second fixing component, can fix the baffle plate with an arc shape. Furthermore, the first fixing component can flexibly adjust the interval between itself and the second fixing component through the sliding component, which can adapt to various types of baffle plates to achieve fixation. The operation is simple, the installation efficiency is high, the installation accuracy can be guaranteed, and the work efficiency can be effectively improved. Attached Figure Description

[0023] This invention discloses a baffle fixing mechanism. The following describes one embodiment of the invention in detail with reference to the accompanying drawings.

[0024] Combination Figure 1 and Figure 2 As shown, a baffle plate fixing mechanism includes a frame 1, a first fixing component, a second fixing component, and a baffle plate 13. The first fixing component is located on the left side of the top of the frame 1, and the second fixing component is located on the right side of the top of the frame 1. The baffle plate 13 is disposed between the first fixing component and the second fixing component. U-shaped plates 9 are fixedly connected to both the left and right sides of the bottom of the frame 1, and the two U-shaped plates 9 are arranged in the same direction. Several double-sided track wheels 10 are rotatably connected inside each U-shaped plate 9, and several lifting rings 11 are fixed to the top of each U-shaped plate.

[0025] like Figure 3 As shown, the first fixing component includes a first support frame and a plate clamping block 5. The first support frame includes a sliding plate 2, a support plate 4, and a baffle 3. The sliding plate 2 is arranged horizontally, and the baffle 3 is vertically fixedly connected to the right side of the top wall of the sliding plate 2. There are two support plates 4, both of which are triangular. The bottom walls of the two support plates 4 are fixedly connected to the top wall of the sliding plate 2, and the right side walls are fixedly connected to the left side wall of the baffle 3. The plate clamping block 5 is vertically fixedly connected to the upper part of the right side wall of the baffle 3, and a first clamping groove is provided on the plate clamping block 5. The first clamping groove has a V-shaped cross section and can be adapted to the deflector plate 13. A sliding component is provided between the first fixing component and the frame 1. The first fixing component adjusts the distance between itself and the second fixing component through the slider component. The sliding component includes several sliders with a convex cross section and several slide rails with a concave cross section. The sliders are arranged in the slide rails 8, and several sliders are fixedly connected to the bottom wall of the sliding plate 2, and several slide rails 8 are fixedly connected to the top wall of the frame 1.

[0026] like Figure 4 As shown, the second fixing component includes a second support frame and a limiting pin. There are two second support frames, arranged symmetrically from left to right. Each second support frame includes a pair of base plates 6 and a pair of connecting plates 7. The connecting plates 7 are right-angled trapezoids. The bottom wall of the base plate 6 is fixedly connected to the top wall of the frame 1, and the bottom wall of the connecting plate 7 is fixedly connected to the top wall of the base plate 6. The gap between the two base plates 6 and the gap between the two connecting plates 7 form a second slot, which is adapted to the baffle plate 13.

[0027] Combination Figure 5 and Figure 6 As shown, a semi-circular pad 12 is fixed in the second slot. A limiting pin is located between the two second support frames. The limiting pin includes a housing, a pin head 15, and a spring. A limiting plate is fixedly connected to the bottom of the pin head 15, and the edge of the limiting plate protrudes beyond the bottom edge of the pin head 15. The housing has a cavity, and the limiting plate is disposed within the cavity. The opening of the cavity narrows to prevent the limiting plate from detaching from the cavity. The spring is located between the bottom of the limiting plate and the bottom of the cavity, allowing the pin head 15 to extend and retract relative to the housing.

[0028] The baffle plate 13 is in the shape of an arc. Several mounting holes adapted to the heat exchange tubes are provided on the baffle plate 13. A notch is provided at the bottom edge of the baffle plate 13, and a limiting port 14 is formed by the notch. The limiting port 14 can be adapted to the plug head 15.

[0029] In use, the operator first places the baffle plate 13 into the second slot on the second support frame, with the edge of the baffle plate 13 contacting the pin head 15, and then presses the pin head 15 downward into the cavity of the housing. The contact area between the arc-shaped baffle plate 13 and the semi-circular pad 12 is small, resulting in low friction, which facilitates the user to rotate the baffle plate 13 to adjust its position relative to the second slot, so that the limiting port 14 corresponds to the limiting pin. When the limiting port 14 corresponds to the limiting pin, the limiting head extends upward under the elastic potential energy of the spring and inserts into the limiting port 14 to prevent the baffle plate 13 from rotating relative to the second slot. The user moves the first fixing component through the sliding component, so that the baffle plate 13 is positioned in the first slot on the plate block 5, which supports the baffle plate 13. The slider of the sliding component is equipped with a slider lock. The user can fix the slider within the slide rail 8 using the adjustable locking handle on the slider lock, preventing the slider from moving relative to the slide rail 8, thereby fixing the first fixing component. In this embodiment, the first fixing component can flexibly adjust the distance between itself and the second fixing component through the sliding component, making it suitable for fixing various types of baffles 13.

[0030] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
