Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to an ultrasonic cleaner for ductile iron casting samples. Background Technology

[0002] The ultrasonic cleaner for ductile iron test specimens is a specialized device for cleaning contaminants on the surface of ductile iron test specimens. Its core technology is to achieve efficient and non-destructive cleaning through ultrasonic vibration. Its cleaning ability comes from the "cavitation effect". The ultrasonic generator converts electrical energy into high-frequency electrical signals, and the transducer converts the electrical signals into high-frequency mechanical vibrations, which are transmitted to the liquid in the cleaning tank. A large number of tiny bubbles are generated in the liquid. The bubbles are rapidly generated and burst, generating local high-pressure shock waves that peel off the dirt from the surface of the specimen. Some ultrasonic cleaners for ductile iron casting samples have a heating function, which can be used with special cleaning agents to improve the cleaning efficiency of oil and cutting fluid. They are also equipped with a timer function to control the cleaning time. When cleaning batches of ductile iron ring samples, operators often stack the samples to increase the throughput per batch. To save space, the samples are placed against the inner wall of the cleaning tank. When stacked, closed gaps are formed between the samples. The upper samples block the downward transmission of high-frequency vibrations, and the vibration intensity of the lower samples drops sharply. When the samples are placed against the wall, the tank absorbs some of the vibration energy, and the vibration of the sample against the wall is attenuated. The stacking of samples causes mutual obstruction between them, and vibration shadow areas are formed on the inner side and in the gaps. Since ultrasonic cleaning relies on the shock waves generated by cavitation effect to remove dirt, the vibration is blocked, and the shadow area cannot form an effective shock wave, resulting in dirt residue and affecting the accuracy of subsequent analysis and hardness testing. Therefore, an ultrasonic cleaner for ductile iron casting samples is proposed to address the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an ultrasonic cleaner for ductile iron casting samples to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An ultrasonic cleaner for ductile iron casting samples includes an ultrasonic generator. A cleaning tank is fixedly connected to one side of the ultrasonic generator. A drain valve is fixedly connected to one side of the bottom of the cleaning tank via a pipe. An all-around cleaning device is fixedly connected to the inner bottom of the cleaning tank. The all-around cleaning device includes an electric telescopic rod. A movable shell is fixedly connected to the telescopic end of the electric telescopic rod. A groove is formed on the inner side wall of the movable shell, and a placement component is provided inside the groove. A drive motor housing is fixedly connected to the bottom of the cleaning tank. The main shaft of the drive motor passes through a rotating shell fixed to the bottom of the cleaning tank. An agitation groove is formed inside the rotating shell, and a rotating plate is fixedly connected to the bottom outer side of the rotating shell.

[0005] As a further optimization of this utility model, the slide groove extends vertically along the inner sidewall of the movable shell, the cross-sectional shape of each slide groove is rectangular, the width of the slide groove is the same as the thickness of the slider, and the depth of the slide groove is half the thickness of the sidewall of the movable shell.

[0006] As a further optimization of this utility model, the placement component includes a slider, a compression spring is fixedly connected to the bottom of the slider, a placement rod is fixedly connected to one side of the compression spring, a sponge pad is adhered to the outside of the placement rod, and a limit block is engaged at the other end of the placement rod.

[0007] As a further optimization of this utility model, the number of sponge pads is the same as the number of placement rods, each sponge pad completely covers the outer wall of the corresponding placement rod, the outer wall of the sponge pad is completely in contact with the inner wall of the cast iron part, and the contact area between the sponge pad and the cast iron part is equal.

[0008] As a further optimization of this utility model, the number of compression springs corresponds one-to-one with the number of placement rods, each compression spring is located on the side of the placement rod near the slider, and the bottom of the compression spring is fixedly connected to the bottom of the slide groove.

[0009] As a further optimization of this utility model, the number of agitation grooves is multiple, and the multiple agitation grooves are evenly distributed at 60° intervals along the inner sidewall of the rotating shell. The shape of each agitation groove is arc-shaped, and the arc direction of the agitation groove is consistent with the rotation direction of the rotating shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, an all-around cleaning device is used. The annular sample is placed on the outside of the placement rod and rises and falls synchronously with the rotating plate. The sponge pad completely fits the inside of the sample, which not only avoids scratches from metal contact but also ensures uniform transmission of ultrasonic vibration. The rotating plate uses rubber pads to increase resistance and prevent slippage, driving the sample to rotate and ensuring full-angle contact and cleaning of the outer wall. The spaced arc-shaped stirring tanks are adapted to the rotation direction, driving the cleaning fluid to form a circulation, which promptly removes loose dirt. The circulation and ultrasonic cavitation effect are superimposed to completely eliminate the residual hazards that are easily caused by improper placement such as stacking or sticking to the wall, providing a reliable basis for subsequent analysis, hardness testing and other tests.

Detailed Implementation

[0014] 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.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-7 This utility model provides a technical solution: An ultrasonic cleaner for ductile iron casting samples includes an ultrasonic generator 1. A cleaning tank 2 is fixedly connected to one side of the ultrasonic generator 1. A drain valve 4 is fixedly connected to one side of the bottom of the cleaning tank 2 via a pipe. An all-around cleaning device 3 is fixedly connected to the inner bottom of the cleaning tank 2. The all-around cleaning device 3 includes an electric telescopic rod 31. A movable shell 32 is fixedly connected to the telescopic end of the electric telescopic rod 31. A groove 33 is opened on the inner side wall of the movable shell 32. A placement component 34 is provided inside the groove 33. The housing of a drive motor 35 is fixedly connected to the bottom of the cleaning tank 2. The main shaft of the drive motor 35 passes through the bottom of the cleaning tank 2 and is fixedly connected to a rotating shell 36. An agitation groove 37 is opened on the inner side of the rotating shell 36. A rotating plate 38 is fixedly connected to the bottom of the outer side of the rotating shell 36.

[0017] It should be noted that the placement component 34 includes a slider 341, a compression spring 345 is fixedly connected to the bottom of the slider 341, a placement rod 342 is fixedly connected to one side of the compression spring 345, a sponge pad 343 is glued to the outside of the placement rod 342, and a limit block 344 is snapped into the other end of the placement rod 342.

[0018] Specifically: the number of sponge pads 343 is the same as the number of placement rods 342. Each sponge pad 343 completely covers the outer wall of the corresponding placement rod 342. The outer wall of the sponge pad 343 is completely in contact with the inner wall of the cast iron part. The contact area between the sponge pad 343 and the cast iron part is equal. The number of compression springs 345 corresponds one-to-one with the number of placement rods 342. Each compression spring 345 is located on the side of the placement rod 342 near the slider 341. The bottom of the compression spring 345 is fixedly connected to the bottom of the slide groove 33.

[0019] Furthermore: the placement rod 342 provides a clear mounting carrier for the sample. The annular ductile iron part can be directly fitted into the placement rod 342, and the limiting block 344 is used to axially limit the sample, preventing the sample from falling off the placement rod 342 during cleaning. When disassembling, only the limiting block 344 needs to be removed to take out the sample, which is convenient. In view of the hollow feature of the annular ductile iron part, the placement rod 342 can be inserted into the inside of the sample to achieve precise positioning of the sample. This avoids the problem of the annular sample rolling easily and being difficult to fix in traditional cleaning, and ensures that the sample position is stable during the cleaning process.

[0020] Another step: When the rotating plate 38 rotates to the highest position, it can drive the sample and the placement rod 342 to stretch and compress the spring 345 upward. When it rotates to the lowest position, the spring restores its elasticity and drives the sample and the placement rod 342 to move downward, realizing the up-and-down reciprocating motion of the sample in the cleaning liquid, breaking the local static state of the cleaning liquid, and increasing the contact frequency between the sample surface and the cleaning liquid.

[0021] As a further implementation of this solution, the chute 33 extends vertically along the inner wall of the movable shell 32. The cross-sectional shape of each chute 33 is rectangular. The width of the chute 33 is the same as the thickness of the slider 341. The depth of the chute 33 is half the thickness of the side wall of the movable shell 32. There are multiple agitation grooves 37. The multiple agitation grooves 37 are evenly distributed at 60° intervals along the inner wall of the rotating shell 36. The shape of each agitation groove 37 is arc-shaped, and the arc direction of the agitation groove 37 is consistent with the rotation direction of the rotating shell 36.

[0022] Specifically: A ring-shaped ductile iron part is installed on the outside of the placement rod 342. The outside of the ring-shaped ductile iron part is in close contact with the upper end of the rotating plate 38. A rubber pad is provided on the contact surface between the rotating plate 38 and the ring-shaped ductile iron part.

[0023] Furthermore, the groove 33 extends vertically and has a rectangular cross-section. With the same width and thickness as the slider 341, it can prevent the slider 341 from swaying or shifting during movement, ensuring that the placement component 34 drives the sample to move up and down. The elastic characteristics of the compression spring 345 can buffer the impact force when the sample moves up and down, preventing the sample from being damaged due to hard contact.

[0024] Furthermore, when the rotating shell 36 rotates, the arc-shaped stirring tank 37 can actively agitate the cleaning fluid. Combined with the design of evenly distributed 60-degree intervals, the cleaning fluid forms a multi-directional, dead-angle-free circulation within the cleaning tank 2, improving the efficiency of dirt removal. The outer side of the annular ductile iron part is in close contact with the upper end of the rotating plate 38. When the rotating plate 38 rotates, it can drive the sample to rotate synchronously through friction, so that all parts of the outer wall of the sample can be evenly contacted by ultrasonic vibration and flowing cleaning fluid. The rubber pad on the contact surface between the rotating plate 38 and the sample is soft, which can avoid direct friction between the metal rotating plate 38 and the outer side of the cast iron sample, preventing scratches and wear on the outer side of the sample and ensuring the accuracy of sample testing.

[0025] Work process: First, turn on the power supply of the equipment, then start the extension and retraction of the electric telescopic rod 31, which drives the moving shell 32 to move upward. Then, align the annular ductile iron sample with the placement rod 342 of the placement assembly 34. Since there is a sponge pad 343 bonded to the outside of the placement rod 342 and the number of sponge pads 343 is the same as that of the placement rod 342, the inner side wall of the sample can be directly fitted into the outside of the placement rod 342 with the sponge pad 343 attached. Then, start the electric telescopic rod 31 again, which drives the moving shell 32 and the installed annular ductile iron sample to move downward until the outer side of the annular ductile iron sample is in close contact with the upper end of the rotating plate 38. Then, add a cleaning fluid suitable for the dirt on the ductile iron parts into the cleaning tank 2. The amount added should meet the following requirements: the cleaning fluid level can completely submerge the annular ductile iron part sample after it has been lowered to the bottom, and should not exceed two-thirds of the height of the inner side of the cleaning tank 2, so as to avoid the cleaning fluid overflowing during the cleaning process. When the ultrasonic generator 1 is turned on, it converts electrical energy into a high-frequency electrical signal and transmits this signal to the vibration component inside the cleaning tank 2, providing high-frequency vibration energy for subsequent cleaning. At the same time, the drive motor 35 is started, and its main shaft drives the rotating shell 36 and the rotating plate 38 to rotate. The rotating plate 38 is wave-shaped. When it rotates to the lowest point, it will drive the annular ductile iron sample, the slider 341, and the placement rod 342 to move downwards, and the compression spring 345 will return to its initial elastic force. When it rotates to the highest point, it will drive the annular ductile iron sample, the slider 341, and the placement rod 342 to move upwards, and the compression spring 345 will stretch. At the same time, the outer side of the annular ductile iron sample is in close contact with the rubber pad at the upper end of the rotating plate 38. When the rotating plate 38 rotates, it will drive the annular ductile iron sample to rotate, which can effectively clean the surface of the annular ductile iron sample from all directions.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
