Description

Technical Field

[0001] This utility model belongs to the technical field of heat exchangers for para-aramid production, and particularly relates to a high-efficiency heat exchanger. Background Technology

[0002] Para-aramid, also known as para-aromatic polyamide fiber, is one of the world's three major high-performance fibers. It is obtained by dry-jet wet spinning of poly(p-phenylene terephthalamide) resin. In the production of para-aramid, solid phenylenediamine and solid phthaloyl chloride are heated and melted separately. Then, a polar solvent and the phenylenediamine melt are metered and continuously added simultaneously in a static mixer at a specific ratio to form a phenylenediamine solution. The solution is then cooled to -15 to 5°C in a heat exchanger before being fed into the next process.

[0003] When cooling a solution, a plate heat exchanger is typically used. A plate heat exchanger usually has two fixed plates with several heat exchange plates placed side-by-side between them. However, during installation, the heat exchange plates are usually positioned by using U-shaped grooves on the plates to engage with support rods on one of the fixed plates. This engagement only restricts the vertical and horizontal movement of the heat exchange plates, not their forward and backward swaying. This makes the heat exchange plates prone to tilting and bending during placement, requiring workers to manually hold them in place to prevent tilting and bending, resulting in low installation efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency heat exchanger, characterized in that it further includes:

[0005] The mounting frame is U-shaped and has an upper side and a lower side;

[0006] The movable panel is set within the mounting frame, allowing it to move back and forth.

[0007] A fixing plate is fixedly installed at the U-shaped opening of the mounting frame;

[0008] The heat exchange plates are arranged in a number that are movably positioned within the mounting frame and between the movable plate and the fixed plate.

[0009] The mounting frame has T-shaped strips at both the lower end of the upper side and the upper end of the lower side.

[0010] The movable plate and the heat exchange plate are provided with T-shaped grooves at both the upper and lower ends, which match the T-shaped bars.

[0011] Furthermore, it also includes:

[0012] The mounting slot is provided on the mounting frame, and the T-shaped strip is detachably connected to the mounting frame;

[0013] A guide assembly used to guide the T-bar as it enters the mounting frame;

[0014] A fixing component used to fix the position of the T-strip;

[0015] The T-shaped strip passes through the mounting groove and enters the mounting frame.

[0016] Furthermore, the fixing component includes:

[0017] A fixing piece is fixedly provided at the end of the T-shaped strip away from the fixing plate;

[0018] Threaded post, which is fixedly installed on the outside of the mounting frame;

[0019] A pressure block, which is sleeved on a threaded post, with one end of the pressure block abutting against a fixing plate;

[0020] A fixing nut, the screw of which is provided on a threaded post, and one end of the fixing nut abuts against the pressure block;

[0021] Wherein, after the T-shaped strip passes through the mounting groove and is inserted into the mounting frame, the fixing piece is located outside the mounting frame and is in contact with the mounting frame.

[0022] Furthermore, the pressure block is in the shape of a cuboid block, with the upper section of the pressure block abutting against the fixing plate, and the lower section of the pressure block rotatably sleeved on the threaded column.

[0023] Furthermore, the guiding component includes:

[0024] The guide strip is fixedly installed at one end of the vertical plate of the T-shaped strip;

[0025] Guide grooves are provided on both the upper and lower sides of the mounting frame;

[0026] The guide groove and the mounting groove are connected.

[0027] Furthermore, it also includes:

[0028] A positioning post is fixedly installed at one end of the fixing plate, and at least two positioning posts are provided.

[0029] Positioning holes: The end face of the mounting frame is provided with positioning holes that match the positioning posts;

[0030] The positioning hole is matched with the positioning post.

[0031] Furthermore, it also includes:

[0032] Positioning grooves are provided at both the upper and lower ends of the movable plate and the heat exchange plate, and the width of the positioning grooves matches the upper and lower sides of the mounting frame.

[0033] The beneficial effects of this utility model are as follows:

[0034] 1. By incorporating T-slots and T-bars, the heat exchange plates are positioned and guided during installation through the interaction of the T-slots and T-bars. Simultaneously, the upper and lower ends of the heat exchange plates engage with the upper and lower sides of the mounting frame via the T-slots and T-bars, respectively, thus positioning the heat exchange plates and preventing them from swaying back and forth. This eliminates the need for workers to press down on the heat exchange plates to prevent tilting, improving installation efficiency.

[0035] 2. By setting the mounting slot, the T-shaped bar can be detachably connected to the mounting frame. When it is necessary to inspect one of the heat exchange plates separately, the T-shaped bar can be removed through the mounting slot, thereby removing the restriction of the T-shaped bar on the heat exchange plate and allowing the heat exchange plate that needs to be inspected to be removed separately.

[0036] 3. By setting up a fixing component, the T-strip can be easily fixed, preventing it from moving during use and thus ensuring the stability of this utility model during use.

[0037] 4. Since the pressure block is in the shape of a cuboid, the upper part of the pressure block abuts against the fixing plate, and the lower part of the pressure block is rotatably sleeved on the threaded post, forming a quick-release structure. When it is necessary to release the pressure of the fixing plate of the pressure block, simply loosen the fixing nut to release the pressure of the pressure block. Since the pivot of the pressure block is in the lower part, the pressure block can rotate downward due to the weight of the upper end, releasing the obstruction of the fixing plate, making it more convenient and quick to remove the T-shaped strip.

[0038] 5. By setting guide bars and guide grooves, as the T-shaped strip passes through the mounting groove and enters the mounting frame, the guide bar of the T-shaped strip also moves in the guide groove. The guide bar is also T-shaped, which makes the position of the T-shaped strip stable, ensuring the positioning and use effect of the T-shaped strip.

[0039] 6. By setting positioning posts and positioning holes, the installation between the fixed plate and the mounting frame is effectively positioned. At the same time, it makes it easier to align the holes between the fixed plate and the movable plate, thus improving installation efficiency.

[0040] 7. By setting the positioning groove, when the T-strip mates with the T-groove, the upper and lower sides of the mounting frame can also be located within the positioning groove and mate with it, making the performance more stable. At the same time, when the T-strip is removed, the positioning groove and the upper and lower sides of the mounting frame can also play a temporary positioning role, preventing the heat exchange plates that have not been removed from the mounting frame and ensuring that the remaining heat exchange plates are in the mounting frame.

Detailed Implementation

[0051] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings indicate similar items, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings. Example 1

[0052] This embodiment provides a high-efficiency heat exchanger, which also includes:

[0053] Mounting frame 1 is U-shaped and has an upper side 2 and a lower side 3;

[0054] The movable plate 4 is set to move back and forth within the mounting frame 1;

[0055] The fixing plate 5 is fixedly installed at the U-shaped opening of the mounting frame 1;

[0056] The heat exchange plates 6 are a plurality of which are movably arranged in the mounting frame 1 and located between the movable plate 4 and the fixed plate 5.

[0057] T-shaped strip 7, the lower end of the upper side 2 and the upper end of the lower side 3 of the mounting frame 1 are both provided with T-shaped strip 7;

[0058] T-slots 8 are provided at both the upper and lower ends of the movable plate 4 and the heat exchange plate 6, which are matched with T-slots 7.

[0059] In this technical solution, during installation, the T-slot 8 of the movable plate 4 is first aligned with the T-strip 7 of the mounting frame 1 and inserted, so that the T-slots 8 at the upper and lower ends of the movable plate 4 are inserted into the T-strip 7 on the upper side 2 and lower side 3 of the mounting frame 1, respectively. This allows the movable plate 4 to be moved back and forth within the mounting frame 1 through the cooperation of the T-strip 7 and the T-slot 8. Then, multiple heat exchange plates 6 to be installed are inserted into the mounting frame 1 in the same way. Since the upper and lower ends of the heat exchange plates 6 cooperate with the upper side 2 and lower side 3 of the mounting frame 1 through the cooperation of the T-slot 7 and the T-slot 8, the upper and lower ends of the heat exchange plates 6 are positioned, preventing the heat exchange plates 6 from swaying back and forth. This eliminates the need for workers to press down on the heat exchange plates 6 to prevent tilting, thus improving installation efficiency.

[0060] After all the heat exchange plates 6 are installed, the fixed plate 5 is connected to the opening of the mounting frame 1. Both the fixed plate 5 and the heat exchange plates 6 have medium flow channels for heat exchange, and they are set accordingly during installation (the working principle of the plate heat exchanger is existing technology and will not be described in detail here). At the same time, multiple grooves are opened on the fixed plate 5 and the movable plate 4. After the fixed plate 5 is fixed, the movable plate 4 is pulled towards the fixed plate 5 by the cooperation of screws and nuts, so that the movable plate 4, the heat exchange plates 6 and the fixed plate 5 are fitted together, and the installation of the plate heat exchanger is completed.

[0061] Through this structural design, by setting T-slots 8 and T-bars 7, the heat exchange plates 6 can be positioned and guided during installation through the cooperation of T-slots 8 and T-bars 7. At the same time, because the upper and lower ends of the heat exchange plates 6 cooperate with the upper side 2 and lower side 3 of the mounting frame 1 respectively through the cooperation of T-bars 7 and T-slots 8, the upper and lower ends of the heat exchange plates 6 are positioned, preventing the heat exchange plates 6 from swaying back and forth. This eliminates the need for workers to press down on the heat exchange plates 6 to prevent tilting, thus improving installation efficiency.

[0062] Meanwhile, the cooperation between the T-shaped strip 7 and the T-shaped groove 8 can make this utility model more stable. Due to the better positioning effect of the heat exchange plate 6, leakage damage caused by vibration is reduced, thereby indirectly improving the heat exchange efficiency. Example 2

[0063] This embodiment provides a high-efficiency heat exchanger, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0064] Furthermore, it also includes:

[0065] Mounting slot 9 is provided on mounting frame 1, and T-shaped strip 7 is detachably connected to mounting frame 1;

[0066] A guide assembly is used to guide the T-shaped strip 7 as it enters the mounting frame 1;

[0067] A fixing component used to fix the position of the T-strip 7;

[0068] The T-shaped strip 7 passes through the mounting groove 9 and enters the mounting frame 1.

[0069] Due to the original design, if the T-shaped strip 7 is fixedly connected to the mounting frame 1, the fit between the T-shaped strip 7 and the T-shaped groove 8 makes it inconvenient to remove the heat exchange plate 6. When it is necessary to remove and replace the heat exchange plate 6, the whole unit needs to be disassembled, and then the heat exchange plate 6 needs to be removed one by one along the T-shaped strip 7, which makes it difficult to inspect the heat exchange plate 6 individually.

[0070] In this technical solution, the T-shaped strip 7 is detachably connected to the mounting frame 1 by setting the mounting groove 9. At the same time, when it is necessary to repair one of the heat exchange plates 6 separately, the T-shaped strip 7 can be removed through the mounting groove 9, thereby releasing the restriction of the T-shaped strip 7 on the heat exchange plate 6, so that one heat exchange plate 6 that needs to be repaired can be taken out separately. After the repair is completed, the heat exchange plate 6 is put back, and the T-shaped strip 7 is inserted again, so that the T-shaped strip 7 is inserted into the mounting groove 9 of the movable plate 4 and the heat exchange plate 6. Finally, the T-shaped strip 7 is fixed by the fixing component to complete the positioning restriction.

[0071] Through this structural design, the T-shaped bar 7 is detachably connected to the mounting frame 1 by setting the mounting groove 9. When it is necessary to repair one of the heat exchange plates 6 separately, the T-shaped bar 7 can be removed through the mounting groove 9, thereby removing the restriction of the T-shaped bar 7 on the heat exchange plate 6, and thus removing one of the heat exchange plates 6 that needs to be repaired separately. Example 3

[0072] This embodiment provides a high-efficiency heat exchanger, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0073] Furthermore, the fixing component includes:

[0074] Fixing piece 10, the T-shaped strip 7 is fixedly provided with a fixing piece 10 at the end away from the fixing plate 5;

[0075] Threaded post 11 is fixedly installed on the outside of mounting frame 1;

[0076] A pressure block 12 is sleeved on a threaded post 11, and one end of the pressure block 12 abuts against a fixing piece 10;

[0077] A fixing nut 13 is screwed onto a threaded post 11, and one end of the fixing nut 13 abuts against the pressure block 12;

[0078] Wherein, after the T-shaped strip 7 passes through the mounting groove 9 and is inserted into the mounting frame 1, the fixing piece 10 is located outside the mounting frame 1 and is in contact with the mounting frame 1.

[0079] In this technical solution, the fixing piece 10 is larger than the mounting groove 9. After one end of the T-shaped strip 7 passes through the mounting groove 9 and is inserted into the mounting frame 1, the fixing piece 10 at the other end of the T-shaped strip 7 will contact the outer side of the mounting frame 1. At this time, the pressure block 12 and the fixing nut 13 are sequentially put into the threaded post 11. The fixing nut 13 is turned so that the fixing nut 13 rotates on the threaded post 11 and moves toward the pressure block 12 through the threaded transmission. Thus, the movement of the fixing nut 13 drives the pressure block 12 to press toward the fixing piece 10, thereby fixing the T-shaped strip 7 and preventing the T-shaped strip 7 from moving.

[0080] This structural design incorporates a fixing component, which facilitates the fixation of the T-shaped strip 7, preventing it from moving during use and thus ensuring the stability of the invention during use. Example 4

[0081] This embodiment provides a high-efficiency heat exchanger, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0082] Furthermore, the pressure block 12 is in the shape of a cuboid block, the upper section of the pressure block 12 abuts against the fixing plate 10, and the lower section of the pressure block 12 is rotatably sleeved on the threaded column 11.

[0083] With this structural design, since the pressure block 12 is a rectangular block, the upper part of the pressure block 12 abuts against the fixing plate 10, and the lower part of the pressure block 12 is rotatably sleeved on the threaded post 11, forming a quick-release structure. When it is necessary to release the pressure of the fixing plate 10 of the pressure block 12, simply loosen the fixing nut 13, so that the pressure of the pressure block 12 disappears. Since the pivot of the pressure block 12 is in the lower part, the pressure block 12 can rotate downward due to the weight of the upper end, releasing the obstruction of the fixing plate 10, making it more convenient and faster to remove the T-shaped strip 7. Example 5

[0084] This embodiment provides a high-efficiency heat exchanger, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0085] Furthermore, the guiding component includes:

[0086] Guide bar 14 is fixedly installed at one end of the vertical plate of T-shaped bar 7;

[0087] Guide groove 15, both the upper side 2 and the lower side 3 of the mounting frame 1 are provided with guide groove 15;

[0088] The guide groove 15 is connected to the mounting groove 9.

[0089] Through this structural design, by setting guide bars 14 and guide grooves 15, as the T-shaped bar 7 passes through the mounting groove 9 and enters the mounting frame 1, the guide bars 14 of the T-shaped bar 7 will also move within the guide grooves 15. The guide bars 14 are also T-shaped, which makes the position of the T-shaped bar 7 stable, ensuring the positioning and use effect of the T-shaped bar 7. Example 6

[0090] This embodiment provides a high-efficiency heat exchanger, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0091] Furthermore, it also includes:

[0092] Positioning post 16 is fixedly installed at one end of the fixing plate 5, and at least two positioning posts 16 are provided;

[0093] Positioning hole 17: The end face of the mounting frame 1 is provided with a positioning hole 17 that matches the positioning post 16;

[0094] The positioning hole 17 is matched with the positioning post 16.

[0095] This structural design, with the positioning post 16 and positioning hole 17, achieves a positioning effect between the fixed plate 5 and the mounting frame 1. At the same time, it makes it easier to align the holes between the fixed plate 5 and the movable plate 4, resulting in better installation efficiency. Example 7

[0096] This embodiment provides a high-efficiency heat exchanger, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0097] Furthermore, it also includes:

[0098] Positioning groove 18 is provided at both the upper and lower ends of the movable plate 4 and the heat exchange plate 6. The width of the positioning groove 18 matches the upper side 2 and the lower side 3 of the mounting frame 1.

[0099] Through this structural design, by setting the positioning groove 18, when the T-shaped strip 7 and the T-shaped groove 8 are engaged, the upper side 2 and the lower side 3 of the mounting frame 1 can also be located in the positioning groove 18 and engage with the positioning groove 18, making the use effect more stable. At the same time, when the T-shaped strip 7 is disassembled, the positioning groove 18 and the upper side 2 and the lower side 3 of the mounting frame 1 can also play a temporary positioning role, preventing the heat exchange plates 6 that have not been disassembled from the mounting frame 1 and ensuring the state of the remaining heat exchange plates 6 in the mounting frame 1.
