Description

Technical Field

[0001] This invention relates to the technical field of centrifuges, and more particularly to a rapid detection device for laboratory centrifuge components and its operating method. Background Technology

[0002] Centrifuges are machines that use centrifugal force to separate the components of a mixture of liquids and solid particles or liquids and liquids. They have a wide range of applications and are suitable for use in laboratories in chemical, food, pharmaceutical, environmental protection, mining, and teaching industries. Therefore, their internal components need to have qualified corrosion resistance to adapt to various corrosive materials. Thus, during the production process of centrifuges, it is necessary to test the corrosion resistance of one of the core internal components, the screw feeder, to ensure its service life.

[0003] A corrosion resistance testing device is disclosed in the existing patent publication number CN219512064U, which includes a base plate and a solution tank disposed on the top outer wall of the base plate. A vertical plate is fixedly installed on the top outer wall of the base plate, and a lifting plate is disposed on one side outer wall of the vertical plate. A connecting rod is fixedly installed on the bottom outer wall of the lifting plate. A placement plate is rotatably installed on the bottom outer wall of the connecting rod through a bearing. A suspension is fixedly installed on the circumferential outer wall of the connecting rod, and a motor is fixedly installed on the circumferential inner wall of the suspension. A drive gear is fixedly installed at one end of the output shaft of the motor, and a gear plate is fixedly installed on the top outer wall of the placement plate.

[0004] In the above technical solution, by rotating the PE pipe body in the solution tank, the PE pipe body can fully react with the solution. However, after the PE pipe is tested, there is still corrosive solution residue on the surface of the PE pipe, which makes it impossible for the staff to remove it directly. They need to wait for it to dry before the next inspection work can be carried out. In addition, the residual solution is easy to drip into the work site, causing pollution to the work environment.

[0005] Therefore, it is necessary to provide a rapid testing device for laboratory centrifuge components and its working method, which can achieve automatic continuous testing. Summary of the Invention

This allows subsequent staff to directly inspect the surface and determine whether the screw conveyor's corrosion resistance is up to standard. The cylindrical baffle also blocks the splashed solution, allowing it to flow back into the solution tank without causing pollution to the working environment, making it highly practical.

[0020] Please see Figure 1-10 The present invention provides a technical solution: a rapid detection device for laboratory centrifuge components and its working method, comprising a transmission line, a solution tank 4, and a rotary table 3. At least one set of rotatable clamping components 1 is provided on the lower side of the rotary table 3. The clamping components 1 are used to clamp the screw feeder 6 back and forth between the solution tank 4 and the transmission line. Several electric telescopic rods are installed between the clamping assembly 1 and the rotary table 3. The electric telescopic rods drive the clamping assembly 1 to rise and fall, and the screw pusher 6 descends and is submerged in the solution tank 4 to conduct corrosion resistance testing. The solution tank 4 is provided with a liftable cylindrical baffle 401 on the inner side. The cylindrical baffle 401 rises with the screw feeder 6 to a position away from the solution tank 4. The clamping assembly 1 drives the screw feeder 6 to rotate and spin dry.

[0021] The transmission line runs through the test bench 9. A receiving groove is provided inside one side of the test bench 9. The solution tank 4 is placed in the receiving groove and slides with it. Several electric telescopic rods are provided at the bottom of the solution tank 4. The transmission line includes a transmission track 501, with several sets of transport seats 502 slidably fitted on the upper side of the transmission track 501. Several transmission wheels are provided on the upper side of the transmission track 501, which are used to drive the transport seats 502 to move. A limiting cylinder 503 is fixedly connected to the upper side of the transport seat 502. Several positioning blocks are provided on the inner side of the limiting cylinder 503. The limiting cylinder 503 is used to place the spiral pusher 6 and the positioning blocks center-position it.

[0022] First, several spiral pushers 6 to be tested are transported to the test platform 9 in sequence via a transmission line. Specifically, the transport seat 502 is driven to move along the transmission track 501 by the rotation of several transmission wheels. The spiral pusher 6 is placed in the limiting cylinder 503 and is centered by several positioning blocks, thereby improving the stability during transportation. The screw pusher 6 to be tested is transported to the test bench 9. Then, the clamping assembly 1 is raised and lowered by the electric telescopic rod 2 to clamp the screw pusher 6 in the limiting cylinder 503. The rotary table 3 is rotated by the rotating shaft 301. The rotary table 3 drives the clamping assembly 1 to move and bring the screw pusher 6 to the upper side of the solution tank 4. Then, while the screw pusher 6 descends, the electric telescopic rod 1 also pushes the solution tank 4 to rise until the screw pusher 6 is submerged in the solution tank 4 for corrosion resistance testing. At this time, the clamping assembly 1 can drive the screw pusher 6 to rotate slowly, thereby accelerating the reaction speed with the solution and improving the testing efficiency. Once the immersion time reaches the test standard, the screw pusher 6 rises to reset and the solution tank 4 descends to reset. Simultaneously, the cylindrical baffle 401 inside the solution tank 4 rises with the clamping assembly 1, always covering the outside of the screw pusher 6 until it is pulled out of the solution. Then, the clamping assembly 1 drives the screw pusher 6 to rotate at high speed, quickly drying the residual solution on the surface. This allows subsequent personnel to directly test the surface and determine whether the corrosion resistance of the screw pusher 6 is up to standard. The cylindrical baffle 401 also blocks the spun-out solution, allowing it to flow back into the solution tank 4, preventing pollution of the working environment and enhancing its practicality. After drying, the cylindrical baffle 401 returns to the inside of the solution tank 4. The rotary table 3 moves the spun-out screw pusher 6 back to the transmission line, then places it back into the same limiting cylinder 503 for unloading. A new screw pusher 6 is then clamped to begin a new round of testing, thus achieving continuous testing with a high degree of automation and significantly improved work efficiency. Preferably, three sets of clamping components 1 are provided and the rotary table 3 rotates intermittently, so that the three stations of loading, testing and unloading can be carried out simultaneously, which further improves work efficiency.

[0023] The clamping assembly 1 includes several clamping blocks 101. A pair of guide rods 102 are fixedly connected to the upper end of each clamping block 101. A clamping disk 103 is slidably fitted to the upper end of each clamping block 101. A plurality of transverse holes 104 are formed through the clamping disk 103. The guide rods 102 pass through the transverse holes 104 and are slidably fitted thereto. A sliding block 105 is fixedly connected to the upper end of each guide rod 102. A plurality of sliding grooves are formed at the upper end of the clamping disk 103. The sliding block 105 is slidably fitted with the sliding grooves. A pair of fixing plates 106 are fixedly connected to the upper end of each sliding block 105. A hinge block 107 is hinged between the pair of fixing plates 106. A V-shaped plate 108 is hinged to the upper end of the hinge block 107. A lifting plate 109 is fixedly connected to the upper end of the plurality of V-shaped plates 108. A guide post 110 is fixedly connected to the upper end of the clamping disk 103. The guide post 110 passes through the lifting plate 109 and is slidably fitted thereto.

[0024] Preferably, when it is necessary to drive the clamping block 101 to clamp the spiral pusher 6, the lifting plate 109 moves upward relative to the clamping plate 103, the guide column 110 guides, the lifting plate 109 pulls several V-shaped plates 108 to rise, the hinge block 107 pulls the sliding block 105, the sliding block 105 moves along the slide groove, driving the guide rod 102 and the clamping block 101 to move, so that the several clamping blocks 101 can move closer to each other and clamp the spiral pusher 6.

[0025] The upper end of the clamping plate 103 is rotatably connected to a threaded rod 111, which passes through the lifting plate 109 and is threadedly connected to it. The clamping assembly 1 also includes a protective top plate 2, the upper end of which is connected to an electric telescopic rod 2. A motor is fixedly connected to the upper end of the protective top plate 2, and the lower end of the motor is connected to the threaded rod 111. The threaded rod 111 passes through the protective top plate 2 and is rotatably connected to it. The upper end of the guide column 110 is connected to the protective top plate 2.

[0026] Preferably, the threaded rod 111 is driven to rotate by a motor component. Under the guidance of the guide post 110, the threaded rod 111 drives the lifting plate 109 to rise and fall, thereby controlling the clamping block 101 to clamp or release the spiral pusher 6. Since the threaded connection has self-locking properties, the threaded rod 111 can lock after driving the lifting plate 109 to rise, maintaining stability, thereby further ensuring the stability of the clamping block 101.

[0027] A circular groove is provided at the lower end of the protective top plate 2. A rotating disk 201 is rotatably connected in the circular groove. The rotating disk 201 is fixedly connected to the guide post 110. A threaded rod 111 passes through the rotating disk 201 and is rotatably connected to it. A square groove is provided on the outer side of the rotating disk 201. A spring telescopic rod 202 is provided in the square groove. One end of the spring telescopic rod 202 is connected to a brake block 203. The brake block 203 slides in cooperation with the square groove. Several brake grooves 204 are provided on the inner side of the protective top plate 2. The brake block 203 is adapted to the brake grooves 204.

[0028] Preferably, in the initial state, the spring force of the spring telescopic rod 202 causes the brake block 203 to be engaged in the brake groove 204, thereby locking the rotating disk 201 and the protective top plate 2 together and fixing them to each other. At this time, the motor drives the threaded rod 111 to rotate, which can guide the guide column 110 to guide and drive the lifting plate 109 to rise, thereby controlling the clamping block 101 to clamp the spiral pusher 6. Next, when the clamping assembly 1 drives the spiral pusher 6 to rotate, the control brake block 203 moves away from the brake groove 204 and retracts into the square groove, thereby releasing the jammed state of the rotating disk 201 and the protective top plate 2. This allows the rotating disk 201 to rotate relative to the protective top plate 2. If the motor continues to drive the threaded rod 111 to rotate at this time, since the clamping block 101 has already clamped the spiral pusher 6, it cannot move further, causing the threaded rod 111 to lock with the lifting plate 109. When the threaded rod 111 rotates again, it directly drives the lifting plate 109 and the clamping disk 103 to rotate, thereby driving the spiral pusher 6 to rotate and perform the spin-drying work. In other words, by only rotating the threaded rod 111, the spiral pusher 6 can be clamped and then driven to rotate, thereby accelerating the reaction speed and spin-drying, which is highly practical.

[0029] The lower end of the cylindrical baffle 401 is fixedly connected to several support members 402. There is a gap between the cylindrical baffle 401 and the solution tank 4. The outer end of the cylindrical baffle 401 is fixedly connected to several double rails 403. The inner side of the solution tank 4 is fixedly connected to several guide bars 404. The guide bars 404 slide in the middle of the double rails 403.

[0030] Preferably, since the cylindrical baffle 401 is located inside the solution tank 4, in order to avoid separating the solution and causing uneven water level height, a support member 402 is provided at the lower end of the cylindrical baffle 401, so that the solution can flow between the gaps on the lower side, ensuring that the raising and lowering of the cylindrical baffle 401 will not affect the water level. Then, a guide bar 404 and a double rail 403 are provided, which slide against each other to guide the cylindrical baffle 401 to be raised and lowered in the center position of the solution tank 4.

[0031] A retaining ring 405 is fixedly connected to the outer side of the upper end of the cylindrical baffle 401. The upper end of the retaining ring 405 is provided with a chamfer. Several protective side plates 302 are fixedly connected to the lower end of the protective top plate 2. A protective ring 308 is fixedly connected to the inner side of the lower end of the protective side plate 302. The inner side of the protective ring 308 is rotatably connected to the clamping plate 103. A hinge rod is hinged between adjacent protective side plates 302. A hinge plate 303 is fixedly connected to the upper and lower ends of the hinge rod. A trapezoidal locking block 304 is fixedly connected to the lower end of the hinge plate 303. The inclined surface of the trapezoidal locking block 304 is adapted to the chamfer of the retaining ring 405. Torsion springs are provided at both ends of the hinge rod. The torsion springs drive the hinge plate 303 to remain in a vertical state.

[0032] Preferably, in the initial state, the torsion spring drives the hinge plate 303 to remain vertical. When the electric telescopic rod 2 drives the protective top plate 2 to descend, causing the spiral pusher 6 to submerge in the solution tank 4, the trapezoidal locking block 304 at the lower end of the hinge plate 303 contacts the retaining ring 405. The trapezoidal locking block 304 moves along its inclined surface, causing the lower side of the hinge plate 303 to deflect outward until the protective ring 308 contacts the upper end of the cylindrical baffle 401. This causes the hinge plate 303 to reset under the reset action of the torsion spring. The trapezoidal locking block 304 engages with the lower end of the retaining ring 405, securing it so that the spiral feeder 6 can be tested. After the test is completed, the clamping assembly 1 rises and resets, and the trapezoidal locking block 304 drives the retaining ring 405 and the cylindrical baffle 401 to rise synchronously. This ensures that the cylindrical baffle 401 always covers the outside of the spiral feeder 6, thus preventing splashed solution from being removed during the spin-drying process. This method is highly practical, does not require an additional drive assembly to drive the cylindrical baffle 401 to rise, saves costs, and has a high degree of automation.

[0033] An upper baffle 406 is rotatably connected to the inner side of the upper end of the cylindrical baffle 401, and an insertion port is provided through the middle side of the upper baffle 406. A central rod 305 is slidably fitted through the inner side of the guide post 110. The lower end of the central rod 305 is slidably fitted through the clamping disk 103. The lower end of the central rod 305 extends to the lower end of the clamping disk 103. A cylindrical cavity is formed on the inner side of the clamping disk 103. A collar 306 is slidably fitted inside the cylindrical cavity. The collar 306 is fixedly connected to the central rod 305. A spring is provided at the upper end of the collar 306. A trapezoidal wedge 307 is fixedly connected to the upper end of the central rod 305. A trapezoidal groove is formed through the inner side of the brake block 203. The trapezoidal wedge 307 is adapted to the trapezoidal groove. A square adaptation hole is formed through the upper side of the protective top plate 2. The square adaptation hole is adapted to the trapezoidal wedge 307.

[0034] Preferably, when it is necessary to drive the brake block 203 to move, thereby releasing the jammed state of the rotating disk 201 and the protective top plate 2, a center rod 305 is provided. Specifically, under the elastic force of the spring, the lower end of the center rod 305 extends to the lower side of the clamping disk 103 and the clamping block 101. After the clamping block 101 clamps the spiral pusher 6, the spiral pusher 6 can be submerged into the solution tank 4. Specifically, the protective top plate 2 is driven to descend by the electric telescopic rod 2, so that the spiral pusher... 6. The rod 305 is inserted into the solution through the insertion port, while the lower end of the central rod 305 contacts the upper baffle 406, keeping the height of the central rod 305 and the trapezoidal wedge 307 constant. As the clamping assembly 1 continues to descend, the trapezoidal wedge 307 passes through the trapezoidal groove and pushes the brake block 203 away from the brake groove 204 along its inclined surface until the trapezoidal locking block 304 engages with the lower end of the retaining ring 405, at which point the brake block 203 is completely disengaged from the brake groove 204 (e.g., ...). Figure 7 As shown), the jamming state of the rotating disk 201 and the protective top plate 2 can be released, thereby driving the spiral pusher 6 to rotate. In other words, by simply using the clamping assembly 1 to drive the spiral pusher 6 to move downward and into the solution tank 4, the jamming state of the rotating disk 201 can be further released, thus making it easier to directly drive the spiral pusher 6 to rotate. This results in a high degree of automation, cost savings, smooth process connection, and improved work efficiency. When the spin-drying operation is required, the trapezoidal clamp 304 restricts the cylindrical baffle 401, which rises with the screw pusher 6. This ensures that the upper baffle 406 always limits the height of the center rod 305, thus keeping the rotating disk 201 rotatable. Then, the screw pusher 6 can be driven to rotate at high speed to perform the spin-drying operation.

[0035] Several clamping plates 8 are fixedly connected to the lower end of the rotary table 3. The lower end of the clamping plate 8 is chamfered, and the upper end of the hinge plate 303 is chamfered. The clamping plate 8 and the hinge plate 303 are compatible.

[0036] After the spin-drying process is completed, when the cylindrical baffle 401 needs to be lowered into the solution tank 4, the electric telescopic rod drives the clamping assembly 1 to continue rising, causing the upper end of the hinge plate 303 to contact the clamping plate 8. This causes the upper end of the hinge plate 303 to slide along its inclined surface, driving the hinge plate 303 to flip. This causes the lower trapezoidal clamping block 304 to move outward, releasing the restriction on the retaining ring 405. This allows the cylindrical baffle 401 to descend and reset. With the center rod 305 no longer restricted, it descends and resets under the reset action of the spring, causing the brake block 203 to return to its original position. Once the brake block 203 is in position, it is re-engaged into the brake groove 204. (If the brake block 203 and the brake groove 204 are not in position at this time, the clamping assembly 1 can continue to be driven to rotate by the threaded rod 111, so that the rotating disk 201 rotates until the brake groove 204 and the brake block 203 are in position.) This will re-engage the rotating disk 201, allowing the threaded rod 111 to drive the clamping block 101, thereby releasing the screw pusher 6 to unload the material, and then clamping the next screw pusher 6 for testing, thus realizing continuous automatic testing function and improving work efficiency.
