Description

Technical Field

[0001] This invention belongs to the field of peristaltic pump technology, and specifically discloses a peristaltic pump for cooling and heat dissipation in optical crystal processing. Background Technology

[0002] As an important fluid transport device, the peristaltic pump works by periodically squeezing a flexible hose with a rotating extrusion wheel (or pressure block), creating negative pressure inside the hose and driving the fluid to flow in a specific direction. This operating method ensures that the fluid being transported only comes into contact with the inner wall of the hose, completely isolating it from the pump's mechanical moving parts. This avoids cross-contamination, metal ion release, and leakage risks associated with mechanical seals. This makes it ideal for fluid transport in optical crystal processing, as the fluid extrusion process is relatively gentle and does not generate high shear forces that could damage or alter the properties of certain polymer additives that may be added to the coolant.

[0003] After prolonged use, the hose of a traditional peristaltic pump wears down, creating a gap between the extrusion wheel and the hose. This results in a reduction in the single extrusion volume, as well as a decrease in outlet pressure and flow rate. This gradual performance degradation subtly alters the heat exchange efficiency of the cooling system, causing temperature control in the crystal processing area to drift, ultimately affecting processing accuracy and product consistency.

[0004] Therefore, those skilled in the art have proposed a peristaltic pump for cooling fluid circulation in optical crystal processing to solve the problems mentioned above. Summary of the Invention

[0012] In the above technical solution, preferably, an installation ring is fixedly connected to the inner wall of the connecting channel, and a baffle is provided on the side of the installation ring near the tray. The baffle covers the inner hole of the installation ring, and a third spring is fixedly connected to the other side of the baffle.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up a squeezing mechanism consisting of a second spring, a slide bar, and a slider, the squeezing gap caused by hose wear can be compensated in real time. Throughout the entire service life of the hose, the mechanism can continuously push the squeezing wheel to keep it close to the hose and maintain a constant squeezing force.

When the wear reaches a preset threshold, the controller can trigger a buzzer alarm to achieve early warning of the fault.

[0020] 3. By setting up an indicator plate mechanism linked to the hydraulic circuit, the internal wear status is converted into an externally visible position movement marked with color, allowing operators to quickly and intuitively determine the remaining life of the hose without disassembling the machine. At the same time, the detachable connection between the baffle and the mounting shell, as well as the hydraulic oil self-sealing design formed by the mounting ring and the baffle, make it easy to disassemble relevant components when replacing hoses or performing maintenance, while ensuring that the hydraulic system does not leak or contaminate the coolant circuit. Maintenance operations are simple, clean, and efficient. Attached Figure Description

Detailed Implementation

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1-9 The illustrated cooling fluid circulating peristaltic pump for optical crystal processing includes a mounting housing 1. A motor 101 is provided on one side of the mounting housing 1, and a baffle 102 is detachably provided on the other side of the mounting housing 1. Two mounting holes are provided on opposite sides of the mounting housing 1 and the baffle 102. The two corresponding mounting holes are joined together to form a mounting groove. A groove is provided on the inner wall of the mounting hole. A mounting tube 202 is provided inside the mounting groove. A protrusion 203 corresponding to the groove is fixedly connected to the surface of the mounting tube 202. A hose 201 is connected to the opposite sides of the two mounting tubes 202. A connecting tube 2 connected to the adjacent mounting tube 202 is detachably provided on the surface of the mounting housing 1 and the baffle 102. A squeezing mechanism 3 is provided on the inner side of the mounting housing 1, and an indicating mechanism 4 is provided on the inner side of the baffle 102.

[0034] The extrusion mechanism 3 includes a tray 301 disposed inside the mounting shell 1. A mounting shaft 302 is fixedly connected to the surface of the tray 301. A drive groove is provided on the inner wall of the mounting shaft 302. The output shaft of the motor 101 passes through the mounting shell 1 and engages with the inner wall of the drive groove. Three guide blocks are slidably connected to the surface of the tray 301 and arranged in a ring. A rotating shaft 303 is rotatably connected to the surface of the guide blocks. An extrusion wheel 304 is fixedly connected to the surface of the rotating shaft 303. An adjustment component is provided between the rotating shaft 303 and the mounting shaft 302.

[0035] Specifically, the installation tube 202 facilitates the installation of the hose 201. The hose 201 is installed in a U-shape between the mounting shell 1 and the baffle 102 with the extrusion mechanism 3 as the center. The protrusion 203 is designed to cooperate with the groove to start the installation of the installation tube 202. The baffle 102 can be fixed to the mounting shell 1 with bolts. The cooperation of the installation tube 202, the protrusion 203 and the groove can reduce the displacement of the hose 201 during the driving process.

[0036] By starting the motor 101, the mounting shaft 302 can be rotated, which in turn drives the rotating shaft 303 to rotate around the mounting shaft 302. During the rotation, the extrusion wheel 304 can be rotated synchronously, thereby achieving the purpose of extruding the hose 201, thus creating a negative pressure inside the hose. The fluid is pumped by alternately extruding and releasing the elastic delivery hose 201.

[0037] like Figures 1-9 As shown, the adjustment assembly includes two rotating rings 307 sleeved on the surface of the rotating shaft 303. The rotating shaft 303 is rotatably connected to the inner wall of the rotating rings 307. A fixed cylinder 305 corresponding to the rotating rings 307 is fixedly connected to the surface of the mounting shaft 302. A slider 317 is slidably connected to the inner wall of the fixed cylinder 305. A slide rod 316 is fixedly connected to one side of the slider 317. The other end of the slide rod 316 passes through the fixed cylinder 305 and is fixedly connected to the surface of the rotating rings 307.

[0038] A second spring 315 is sleeved on the surface of the slide bar 316. One end of the second spring 315 is fixedly connected to the surface of the slider 317, and the other end of the second spring 315 is fixedly connected to the inner wall of the fixed cylinder 305. A liquid storage area is formed between the end of the slider 317 near the slide bar 316 and the inner wall of the fixed cylinder 305.

[0039] An installation area is formed between the other side of the slider 317 and the fixed cylinder 305. A pressure sensor 312 is fixedly connected to the inner wall of the installation area. A buffer pad is provided on one side of the pressure sensor 312. A first spring 314 is fixedly connected between the buffer pad and the slider 317.

[0040] Specifically, the device also includes a controller for controlling the start of the motor 101 and receiving transmitted signals.

[0041] As the pump body operates for a long time, wear will occur on the surface of the hose 201, resulting in gaps in the compression of the hose 201 by the compression wheel 304, which leads to a decrease in compression force and affects the pumping effect.

[0042] By setting a second spring 315, the slide bar 316 can drive the rotating ring 307 to make the squeezing wheel 304 fit tightly against the surface of the hose 201, avoiding poor contact due to wear that would affect the pumping effect. As the slide bar 316 moves, it can stretch the first spring 314, thereby reducing the squeezing of the buffer pad and thus reducing the squeezing of the pressure sensor 312. If the pressure exceeds the preset value, the signal can be transmitted to the controller, which will then activate the buzzer alarm so that the staff can replace the hose 201 in time.

[0043] like Figures 1-9 As shown, a connecting shell 308 is fixedly connected to the surface of the fixed cylinder 305, a connecting cavity 310 is opened inside the mounting shaft 302, a guide channel 313 communicating with the adjustment area is opened inside the fixed cylinder 305, the other end of the guide channel 313 is connected with the connecting cavity 310, and a connecting channel 311 communicating with the connecting cavity 310 is opened at the end of the mounting shaft 302 away from the tray 301.

[0044] An installation ring 318 is fixedly connected to the inner wall of the connecting channel 311. A baffle 309 is provided on the side of the installation ring 318 near the tray 301. The baffle 309 covers the inner hole of the installation ring 318, and a third spring 306 is fixedly connected to the other side of the baffle 309. The other end of the third spring 306 is fixedly connected to the inner wall of the connecting channel 311.

[0045] Specifically, the connecting cavity 310, the guide channel 313, the connecting channel 311 and the adjustment area are all filled with hydraulic oil, so that the hydraulic oil can be squeezed and discharged through the connecting channel 311 by changing the space in the adjustment area during the movement of the slider 317.

[0046] The cooperation of the mounting ring 318, the third spring 306, and the baffle 309 can seal the connecting channel 311 after the baffle 102 is disassembled to prevent hydraulic oil leakage.

[0047] like Figures 1-9 As shown, the indicating mechanism 4 includes a mounting plate 402 fixedly connected to the inside of the baffle 102. One side of the mounting plate 402 is provided with a connecting groove corresponding to the end of the mounting shaft 302. The other side of the mounting plate 402 is fixedly connected with a fixing rod 403. The other end of the fixing rod 403 passes through the baffle 102 and is provided with a buzzer.

[0048] A slip ring 401 is rotatably connected to the inner wall of the connecting groove. A plug rod 407 is fixedly connected to one side of the slip ring 401. A cavity is opened inside the plug rod 407. The diameter of the plug rod 407 corresponds to the inner diameter of the mounting ring 318. A discharge hole 409 communicating with the cavity is opened on the surface of the plug rod 407. A through hole 411 communicating with the cavity is opened on the surface of the slip ring 401. A retaining ring 408 is slidably connected to the surface of the plug rod 407, and the retaining ring 408 blocks the discharge hole 409. A fourth spring 410 is fixedly connected to one side of the retaining ring 408 and the surface of the slip ring 401.

[0049] The fixed rod 403 has a rotating cavity inside, and an indicator plate 404 is rotatably connected to the inner wall of the rotating cavity. The fixed rod 403 has an adjusting cavity 405 inside, and a sliding block 412 is slidably connected to the inner wall of the adjusting cavity 405. A connecting rod is fixedly connected to one side of the sliding block 412, and the other end of the connecting rod is fixedly connected to the surface of the indicator plate 404. A fixed block 413 is also fixedly connected to the inner wall of the adjusting cavity 405. The side of the fixed block 413 that is far away from the sliding block 412 forms a driving cavity with the inside of the adjusting cavity 405. A fifth spring 414 is fixedly connected between the other side of the sliding block 412 and the fixed block 413.

[0050] The fixed rod 403 has a flow channel 406 inside that communicates with the drive cavity. The other end of the flow channel 406 is connected to the adjacent through hole 411. A transparent plate is embedded on the side of the fixed rod 403 away from the mounting plate 402.

[0051] Specifically, the interior of the cavity, flow channel 406, and drive cavity is also filled with hydraulic oil.

[0052] During the installation of the retaining shell 102, the insert rod 407 can be inserted into the interior of the mounting ring 318 and push the baffle 309 to compress the third spring 306. During this process, due to the obstruction of the surface of the mounting ring 318, the retaining ring 408 can be pushed to slide along the surface of the insert rod 407, and the fourth spring 410 is squeezed simultaneously until it is installed in place. At this time, the cavity can be connected to the connecting channel 311 through the discharge hole 409, so that hydraulic oil can flow into the interior of the cavity.

[0053] After installation, as the wear of the hose 201 increases, the compression wheel 304 gradually moves away from the mounting shaft 302, thereby gradually increasing the amount of hydraulic oil injected into the drive chamber. This pushes the sliding block 412 to slide along the inner wall of the adjustment chamber 405 and compresses the fifth spring 414, which in turn drives the indicator plate 404 to move synchronously. During this process, the position of the indicator plate 404 can be observed through a transparent plate. Two different colors can be set on the indicator plate 404 to easily distinguish whether the hose 201 has been excessively worn, so that the staff can replace it in time.

[0054] Working principle: Starting the motor 101 drives the mounting shaft 302 to rotate, which in turn drives the rotating shaft 303 to rotate around the mounting shaft 302. During this rotation, the squeezing wheel 304 rotates synchronously, thus squeezing the hose 201 and creating negative pressure inside. The elastic delivery hose 201 alternately squeezes and releases to pump fluid. During operation, the second spring 315 drives the slide rod 316 to push the rotating ring 307, which in turn causes the squeezing wheel 304 to press tightly against the surface of the hose 201, preventing wear and tear that could affect the pumping effect. Furthermore, the movement of the slide rod 316 stretches the first spring 314, reducing pressure on the buffer pad and thus reducing pressure on the pressure sensor 312. When the pressure exceeds a preset value, a signal is transmitted to the controller, which then activates a buzzer alarm to allow staff to replace the hose 201 in a timely manner. Simultaneously, by setting an indicator mechanism 4, after installation, as the wear of the hose 201 increases, the pressure roller 304 gradually moves away from the mounting shaft 302, thereby gradually increasing the injection of hydraulic oil into the drive chamber. This pushes the sliding block 412 to slide along the inner wall of the adjustment chamber 405 and compresses the fifth spring 414, which in turn drives the indicator plate 404 to move synchronously. During this process, the position of the indicator plate 404 can be observed through a transparent plate. The indicator plate 404 can be set with two different colors to easily distinguish whether the hose 201 has excessive wear, so that staff can replace it in a timely manner.
