Description

Technical Field

[0001] This utility model relates to the field of fluoroplastic heat exchanger technology, specifically an antistatic and corrosion-resistant heat exchanger. Background Technology

[0002] Heat exchangers can be divided into two main categories according to their material properties: metal heat exchangers and non-metal heat exchangers. Non-metal heat exchangers mainly include graphite heat exchangers, ceramic heat exchangers, glass heat exchangers, and plastic heat exchangers. Among them, fluoroplastic heat exchangers, which use fluoroplastics such as polytetrafluoroethylene (PTFE) and perfluoropropylene (PFEP) as the main heat exchange materials, are high-performance representatives of plastic heat exchangers. Compared with traditional metal heat exchangers, their core advantages are excellent corrosion resistance and superior anti-fouling properties. They are important equipment for solving heat transfer problems under strong corrosion and easy-fouling conditions.

[0003] In existing technologies, to ensure the stability and reliability of fluoroplastic heat exchangers during operation, they are usually installed on a pre-set bracket or base using multiple bolts. However, in industrial production, the disassembly and assembly of fluoroplastic heat exchangers is quite cumbersome during regular maintenance and inspection. Tightening and loosening numerous bolts is a time-consuming and labor-intensive task with many steps, making disassembly and assembly somewhat difficult and easily affecting the maintenance efficiency of fluoroplastic heat exchangers. Summary of the Invention

[0004] The purpose of this utility model is to provide an antistatic and corrosion-resistant heat exchanger. Through the structural design of the fixed base, bidirectional screw and T-shaped clamp, the heat exchanger body can be easily disassembled and assembled, solving the problem of the cumbersome disassembly and assembly of the heat exchanger.

[0005] This utility model is achieved through the following technical solution: This utility model relates to an antistatic and corrosion-resistant heat exchanger, comprising a heat exchanger body, a fixed base, and an elastic element. The fixed base has an assembly groove, and both sides of the assembly groove have slots. The bottom of the heat exchanger body is provided with an installation plate, and the bottom of the installation plate has a rectangular groove. A bidirectional screw is rotatably installed in the rectangular groove. The outer surface of the bidirectional screw is fitted with two driving blocks, which cooperate with the rectangular groove. The bottom end of each of the two driving blocks is provided with a T-shaped locking block, which cooperates with the assembly groove and engages with the two slots respectively.

[0006] Furthermore, two circular grooves are formed inside the rectangular groove, and bearings are fitted inside the circular grooves. The two end surfaces of the bidirectional screw are respectively fitted with the inner rings of the two bearings.

[0007] Furthermore, one end of the bidirectional screw passes through the circular groove to the outside of the mounting plate, and a stepper motor is provided on the side of the mounting plate, with the output end of the stepper motor connected to one end of the bidirectional screw.

[0008] Furthermore, two guide grooves are provided on the bottom surface of the mounting plate, and two guide blocks are provided on each of the two T-shaped blocks, with the guide blocks cooperating with the guide grooves.

[0009] Furthermore, there are four elastic elements, including an arc-shaped pressure plate. Two springs are horizontally arranged on one side of the arc-shaped pressure plate. Opening slots are opened on both sides of the two T-shaped blocks. One end of the two springs is fixedly connected to the inner wall of the opening slot. The arc-shaped pressure plate cooperates with the opening slot. Four arc-shaped blocks are arranged in the assembly slot, and the arc-shaped blocks cooperate with the opening slot.

[0010] Furthermore, the arc-shaped pressure plate is provided with two pairs of limiting blocks, and the opening slot is provided with two pairs of limiting grooves, with one pair of limiting blocks cooperating with one pair of limiting grooves.

[0011] This utility model has the following beneficial effects: 1. This utility model, through the structural design of a fixed base, a bidirectional screw, and T-shaped locking blocks, uses the rotation of the bidirectional screw to drive the two T-shaped locking blocks to move towards each other, so that the two T-shaped locking blocks are respectively embedded into the two corresponding slots in the assembly groove, realizing the mechanical locking of the heat exchanger body. This allows for convenient disassembly and assembly of the heat exchanger body, effectively shortening the disassembly and assembly time. The operation is simple and labor-saving, greatly reducing the difficulty of disassembling and assembling the heat exchanger body and ensuring the maintenance efficiency of the heat exchanger body.

[0012] 2. This utility model, through the structural design of the arc-shaped block and elastic element, compresses the spring by moving backward under pressure. The spring's accumulated elastic force is then reflected by the arc-shaped pressure plate onto the arc-shaped block, thus providing a continuous clamping force pointing outward from the slot for the T-shaped locking block in the locked state. This greatly enhances the tightness of the connection, effectively prevents loosening that may occur due to vibration during equipment operation, and enhances the radial stability of the heat exchanger body.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: an antistatic and corrosion-resistant heat exchanger, including a heat exchanger body 1, a fixing seat 2, and an elastic element 6. The fixing seat 2 is provided with an assembly groove 201, and the two side walls of the assembly groove 201 are provided with slots 202. The heat exchanger body 1 is equipped with an antistatic fluoroplastic heat exchange tube bundle, and the surface of the tube sheet inside is covered with a fluoroplastic layer to enhance the corrosion resistance of the heat exchanger body 1. The heat exchanger body 1 is externally connected to an integrated high-efficiency static eliminator and a dedicated grounding device to further enhance the antistatic and corrosion-resistant performance of the heat exchanger body 1.

[0022] A mounting plate 3 is provided at the bottom of the heat exchanger body 1. A rectangular groove 301 is formed at the bottom of the mounting plate 3. A bidirectional screw 4 is rotatably mounted in the rectangular groove 301. Two circular grooves are formed in the rectangular groove 301, and bearings are fitted in the circular grooves. The two ends of the bidirectional screw 4 are respectively engaged with the inner rings of the two bearings to ensure the rotation effect of the bidirectional screw 4 in the rectangular groove 301. One end of the bidirectional screw 4 passes through the circular groove to the outside of the mounting plate 3. A stepper motor 7 is provided on the side of the mounting plate 3. The stepper motor 7 is connected to an external PLC controller, which can precisely control the forward and reverse rotation of the stepper motor 7. The output shaft of the stepper motor 7 is directly connected to one end of the bidirectional screw 4 through a coupling. The forward and reverse rotation of the stepper motor 7 is controlled by the external PLC controller. This allows for precise control of the clamping and releasing actions of the two T-shaped blocks 5. The output end of the stepper motor 7 is connected to one end of the bidirectional screw 4, providing power for the rotation of the bidirectional screw 4 within the rectangular groove 301. Two drive blocks 401 are fitted on the outer surface of the bidirectional screw 4, and the drive blocks 401 engage with the rectangular groove 301. T-shaped blocks 5 are provided at the bottom of each of the two drive blocks 401, and the two T-shaped blocks 5 engage with the assembly groove 201. The two T-shaped blocks 5 are respectively engaged with the two slots 202. Two guide grooves 302 are provided on the bottom surface of the mounting plate 3, and two guide blocks 503 are provided on each of the two T-shaped blocks 5. The guide blocks 503 engage with the guide grooves 302 to ensure the stability of the two T-shaped blocks 5 during their relative movement.

[0023] When the heat exchanger needs to be installed, the stepper motor 7 is first started by controlling the external PLC controller to drive the bidirectional screw 4 to rotate, which in turn drives the two drive blocks 401 and the T-shaped locking blocks 5 to retract towards the center. Then, the T-shaped locking blocks 5 at the bottom of the mounting plate 3 are aligned with the assembly slot 201 on the fixed base 2 and lowered. At this time, the stepper motor 7 is started again and controlled by the PLC controller to rotate in the opposite direction, driving the two T-shaped locking blocks 5 to move in opposite directions. Under the guidance of the guide block 503 and the guide groove 302, the T-shaped locking blocks 5 extend outward smoothly, and their heads are finally embedded in the locking slot 202 in the assembly slot 201, realizing the mechanical locking of the heat exchanger body 1. When maintenance or replacement is required, the stepper motor 7 is started again, which drives the bidirectional screw 4 to drive the T-shaped locking blocks 5 out of the locking slot 202 and retract towards the center. At this time, the entire heat exchanger body 1, together with the mounting plate 3, is lifted upward to separate it from the fixed base 2, realizing the disassembly of the heat exchanger body 1.

[0024] Four elastic elements 6 are provided. Each elastic element 6 includes an arc-shaped pressure plate 601. Two springs 602 are horizontally arranged on one side of the arc-shaped pressure plate 601. Opening slots 501 are provided on both sides of the two T-shaped locking blocks 5. The four elastic elements 6 are respectively installed in the four corresponding opening slots 501. One end of each of the two springs 602 is fixedly connected to the inner wall of the opening slot 501. The arc-shaped pressure plate 601 cooperates with the opening slot 501. Four arc-shaped blocks 203 are provided in the assembly slot 201. The arc-shaped blocks 203 cooperate with the opening slot 501. The four arc-shaped blocks 203 correspond one-to-one with the four opening slots 501. The arc-shaped pressure plate 601 is provided with two pairs of limiting blocks 603, and the opening slots 501 are provided with two pairs of limiting slots 502. The pair of limiting blocks 603 and the pair of limiting slots 502 cooperate to ensure that the arc-shaped pressure plate 601 slides stably in the opening slots 501. The two ends of the four arc-shaped blocks 203 and the two ends of the arc-shaped pressure plate 601 are provided with smooth arc-shaped sliding surfaces, which can facilitate the contact and compression between the arc-shaped blocks 203 and the arc-shaped pressure plate 601.

[0025] During the process of the T-shaped locking block 5 entering the slot 202, the arc-shaped block 203 fixed to the inner wall of the assembly slot 201 will simultaneously embed into the opening slot 501 on the side of the T-shaped locking block 5 and squeeze the arc-shaped pressure plate 601 of the elastic element 6. After being pressed, the arc-shaped pressure plate 601 moves backward and compresses the spring 602. The elastic force stored in the spring 602 reacts to the arc-shaped block 203 through the arc-shaped pressure plate 601, thereby providing a continuous pressing force for the T-shaped locking block 5 in the locked state, pointing towards the outside of the slot 202, and effectively enhancing the stability of the heat exchanger body 1.
