Description

Technical Field

[0001] This utility model relates to the technical field of agitator shaft cleaning devices, specifically an ultrasonic cleaning machine for chemical agitator shafts. Background Technology

[0002] Chemical stirring shafts are in prolonged contact with chemical substances in equipment such as reaction vessels and mixing tanks, and their surfaces are prone to accumulating stubborn dirt (such as polymers and crystals), requiring regular cleaning to maintain performance. Ultrasonic cleaning technology is widely used in the field of chemical instrument cleaning due to its high efficiency and non-contact cleaning characteristics. For example, a Chinese patent (publication number: CN202222628523.3) discloses an ultrasonic cleaner for cleaning chemical instruments, which uses sliding partitions to adjust the cleaning rack space to avoid instrument collisions and uses ultraviolet sterilization to improve efficiency. However, this design is mainly for conventional instruments and does not consider the problem of fixing long rods such as stirring shafts under high-frequency ultrasonic vibration.

[0003] In existing ultrasonic cleaning machines for chemical mixing shafts, the space of the cleaning frame is adjusted by sliding partitions to prevent instrument collisions, but this cannot effectively lock the mixing shaft in place. Because the mixing shaft cannot be securely fixed, the water flow generated by ultrasonic vibration can easily cause the mixing shaft to detach from the cleaning frame, resulting in incomplete cleaning or damage from impact with the tank wall, making it difficult to meet the actual needs of mixing shaft cleaning. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic cleaning machine for chemical stirring shafts, which solves the problem of stirring shaft movement by using a pressure plate and an L-shaped block to lock the stirring shaft.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is an ultrasonic cleaner for chemical mixing shafts, including an ultrasonic cleaner body, a rotating shaft, and an L-shaped block. The ultrasonic cleaner body has a cleaning chamber inside, and a placement basket is placed inside the cleaning chamber. The side plate of the placement basket has a through hole that matches the rotating shaft. A pressure plate is sleeved on the rotating shaft, and a recess is installed at the end of the pressure plate. The side plate of the placement basket has a second sliding groove that matches the L-shaped block. The bottom of the L-shaped block has a limiting part, and the recess has a groove that matches the limiting part.

[0007] Furthermore, torsion springs are fitted at both ends of the rotating shaft, with the two ends of the torsion springs connected to the outer surface of the pressure plate and the inner wall of the through hole, respectively.

[0008] Furthermore, a relief groove is provided in the side plate of the basket, which is connected to the through hole, and the end of the pressing plate is located in the relief groove.

[0009] Furthermore, a reserved slot is provided inside the placement basket, and the reserved slot is connected to the second sliding groove.

[0010] Furthermore, a rubber pad is installed at the bottom of the tablet, and the bottom of the rubber pad has a serrated structure.

[0011] Furthermore, the ultrasonic cleaner body has first grooves on both sides, and sliders are installed on both sides of the basket, with the sliders sliding and engaging in the first grooves.

[0012] This utility model has the following beneficial effects:

[0013] This invention uses a pressure plate and an L-shaped block to lock the stirring shaft, avoiding the problem of the stirring shaft coming off the basket due to ultrasonic vibration. This allows the device to provide stable fixation for long rods, which not only improves the cleaning effect but also avoids the damage to the equipment that may be caused by the stirring shaft coming off the basket, extends the service life of the stirring shaft and the cleaning machine, and reduces maintenance costs.

[0014] This invention protects the stirring shaft with a rubber pad. The serrated structure at the bottom of the rubber pad significantly increases the contact area and friction with the stirring shaft. During the ultrasonic cleaning process, the stirring shaft may experience slight displacement due to vibration. The serrated rubber pad effectively resists this displacement by increasing friction, ensuring the stirring shaft is firmly fixed in the basket and preventing it from coming off. When the stirring shaft is subjected to vibration, the rubber pad acts as a buffer, reducing the direct impact of vibration on the stirring shaft and thus protecting it from damage.

[0015] 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

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an ultrasonic cleaner for a chemical stirring shaft, comprising an ultrasonic cleaner body 1, a rotating shaft 4, and an L-shaped block 7. Both ends of the rotating shaft 4 are fitted with torsion springs 5, and the two ends of the torsion springs 5 ​​are respectively connected to the outer surface of the pressure plate 3 and the inner wall of the through hole 203. The ultrasonic cleaner body 1 has a cleaning chamber 101 inside, and a placement basket 2 is placed inside the cleaning chamber 101. A clearance groove 202 is formed in the side plate of the placement basket 2, and the clearance groove 202 communicates with the through hole 203. The end of the pressure plate 3 is located in the clearance groove. Inside the groove 202, a reserved groove 205 is provided in the basket 2. The reserved groove 205 is connected to the second sliding groove 204. The reserved groove 205 allows the top of the L-shaped block 7 to be pulled easily. A through hole 203 is provided in the side plate of the basket 2 to match the rotating shaft 4. A pressure plate 3 is sleeved on the rotating shaft 4. A recess 6 is installed at the end of the pressure plate 3. A second sliding groove 204 is provided in the side plate of the basket 2 to match the L-shaped block 7. The bottom of the L-shaped block 7 has a limiting part 701. A groove 601 is provided on the recess 6 to match the limiting part 701.

[0023] When cleaning the chemical stirring shaft, pull the top of the L-shaped block 7 between the second slide groove 204 and the reserved groove 205 to make the L-shaped block 7 slide along the second slide groove 204 and compress the spring 8. At this time, the limiting part 701 moves away from the groove 601. Then rotate the pressure plate 3 so that the pressure plate 3 rotates along the rotating shaft 4 into the relief groove 202, so that the torsion spring 5 is compressed. At this time, place the stirring shaft in the placement basket 2. Then release the pressure plate 3 and drive the pressure plate 3 back to its position through the torsion spring 5. At this time, the bottom of the pressure plate 3 contacts the stirring shaft. Press the pressure plate 3 so that the concave block 6 moves to one side of the limiting part 701. Then release the L-shaped block 7 and push the L-shaped block 7 through the spring 8 so that the limiting part 701 enters the groove 601 to limit the concave block 6, so that the L-shaped block 7 locks the stirring shaft and prevents it from moving.

[0024] A rubber pad 9 is installed at the bottom of the pressure plate 3. The bottom of the rubber pad 9 has a serrated structure. While the pressure plate 3 locks the stirring shaft, the rubber pad 9 at the bottom of the pressure plate 3 contacts the stirring shaft. Due to the serrated structure at the bottom of the rubber pad 9, the contact area and friction with the stirring shaft are significantly increased. During the cleaning process of the ultrasonic cleaner body 1, the stirring shaft may have a slight displacement tendency due to vibration. The serrated rubber pad 9 can effectively resist this displacement by increasing the friction, ensuring that the stirring shaft is firmly fixed in the placement basket 2 and preventing it from falling out of the basket. Moreover, when the stirring shaft is vibrated, the rubber pad 9 can play a buffering role.

[0025] The ultrasonic cleaner body 1 has first sliding grooves 102 on both sides, and sliders 201 are installed on both sides of the placement basket 2. The sliders 201 slide in the first sliding grooves 102. When cleaning the stirring shaft, it is placed into the placement basket 2. Then, the sliders 201 slide into the first sliding grooves 102 to place the placement basket 2 into the ultrasonic cleaner body 1. The chemical stirring shaft in the placement basket 2 is cleaned by ultrasonic frame frequency.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
