Description

Technical Field

[0001] This utility model relates to the field of screw cleaning technology, and in particular to a screw cleaning device. Background Technology

[0002] In the screw manufacturing process, the cleaning process is crucial for ensuring the product's appearance and performance. Screw cleaning equipment, in actual operation, requires pre-degreasing, activation, and rinsing with clean water. Currently, if the concentration of the cleaning agent in the pre-degreasing process is insufficient, it cannot effectively remove oil and dirt adhering to the screw's surface and interior, and the residual oil can easily cause the screw to turn white in subsequent processes. Conversely, if the nitric acid concentration in the activation tank is too high, it will cause excessive corrosion to the screw surface, affecting its gloss. This results in a general problem of inconsistent cleaning quality, failing to meet preset standards. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a screw cleaning device that can improve cleaning quality and prevent screws from turning white after cleaning.

[0004] Therefore, the technical solution of this utility model is: a screw cleaning device, comprising a pre-degreasing tank, a first clean water tank, an activation tank, a second clean water tank, and a PLC controller arranged sequentially; the pre-degreasing tank is equipped with a reagent concentration monitoring module and an automatic dosing device, the reagent concentration monitoring module is used to monitor the reagent concentration in the pre-degreasing tank, and the PLC controller controls the operation of the automatic dosing device according to the reagent concentration; the activation tank is equipped with a proportioning module and a gloss agent adding device, and the activation tank is connected to an activator storage tank and a nitric acid storage tank; an ultrasonic generator is provided at the bottom of the activation tank, and the ultrasonic generator is connected to the tank body of the activation tank.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the proportional adjustment module includes a first flow metering valve and a second flow metering valve respectively disposed at the outlets of the activator storage tank and the nitric acid storage tank; the first flow metering valve and the second flow metering valve are electrically connected to the PLC controller.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the ratio of activator to nitric acid in the activation tank is 1:0.8.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the gloss agent adding device includes a gloss agent storage tank, a metering pump and an adding pipeline. The metering pump is electrically connected to a PLC controller, and the PLC controller controls the metering pump to work and deliver the gloss agent into the activation tank.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the ultrasonic generating device includes an ultrasonic generator and a plurality of ultrasonic transducers, the ultrasonic transducers being distributed at the bottom and / or sidewalls of the activation tank.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The chemical concentration monitoring module in the pre-degreasing tank can monitor the chemical concentration in real time. When the concentration is insufficient, the PLC controller will promptly control the automatic dosing device to replenish the chemical, ensuring that there is always a sufficient concentration of chemical to remove oil stains from the surface and inside of the screws, thus preventing the screws from turning white in subsequent processes due to residual oil stains.

[0010] The concentration ratio of activator to nitric acid in the activation tank is controlled at 1:0.8 to avoid excessive nitric acid concentration from corroding the screw surface. At the same time, a metering pump can accurately deliver gloss agent to the activation tank to improve the gloss of the screw surface, thus solving the problem of excessive corrosion and poor gloss of the screw surface during the activation process.

[0011] The ultrasonic transducers evenly distributed on the bottom and side walls of the activation tank work in conjunction with the ultrasonic generator. The ultrasonic waves generate a powerful impact force that can quickly remove stubborn stains and impurities from the screw surface. In particular, it can clean areas that are difficult to reach by conventional cleaning, such as screw threads, making the activation process more efficient and thorough. Attached Figure Description

Detailed Implementation

[0014] In the description of this utility model, it should be noted that the directional terms such as "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0015] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0016] See the attached drawings. The screw cleaning device described in this embodiment includes a pre-degreasing tank 1, a first clean water tank 2, an activation tank 3, a second clean water tank 4, and a PLC controller arranged in sequence.

[0017] The pre-degreasing tank 1 is equipped with a reagent concentration monitoring module and an automatic dosing device. The reagent concentration monitoring module uses a reagent concentration sensor 11. The automatic dosing device includes a reagent storage tank 12 and an electromagnetic metering pump 13. The reagent concentration sensor 11 and the electromagnetic metering pump 13 are electrically connected to the PLC controller. During operation, the reagent concentration sensor 11 monitors the reagent concentration in the pre-degreasing tank 1 in real time. When the concentration is lower than a preset threshold, the PLC controller sends a signal to the electromagnetic metering pump 13, which starts and replenishes the reagent in the pre-degreasing tank 1 until the concentration reaches the preset value. This preset value can be a concentration value that ensures 90% oil removal and can be set according to actual conditions.

[0018] The activation tank 3 is equipped with a proportioning module and a gloss agent adding device. The activation tank is connected to an activator storage tank 31 and a nitric acid storage tank 32. The proportioning module includes a first flow metering valve 33 and a second flow metering valve 34 respectively located at the outlets of the activator storage tank 31 and the nitric acid storage tank 32. The first flow metering valve 33 and the second flow metering valve 34 are electrically connected to a PLC controller. The PLC controller presets parameters to control the delivery of activator and nitric acid, so that the concentration ratio of the two in the activation tank 3 is maintained at 1:0.8.

[0019] The gloss agent adding device includes a gloss agent storage tank 35, a metering pump 36, and an adding pipeline. The metering pump 36 is electrically connected to a PLC controller. The PLC controller controls the metering pump 36 to add gloss agent to the activation tank 3 at regular intervals and in a fixed quantity according to the liquid volume in the activation tank 3 and the preset gloss agent addition ratio.

[0020] An ultrasonic generator is installed at the bottom of the activation tank 3, and the ultrasonic generator is connected to the tank body. The ultrasonic generator includes an ultrasonic generator 51 and several ultrasonic transducers 52, which are distributed on the lower outer wall of the activation tank. During operation, the ultrasonic generator 51 drives the ultrasonic transducers 52 to vibrate, promoting thorough mixing of the reagents in the activation tank 3, preventing reagent precipitation, increasing the activity of each ion, and making the activation effect on the screw surface more uniform.

[0021] During use, the screws to be cleaned are placed into the pre-degreasing tank 1, which is set up sequentially. The agent concentration monitoring module in the tank monitors the agent concentration in real time and feeds back to the PLC controller. If the concentration does not meet the standard, the PLC controller immediately starts the automatic dosing device to replenish the agent, ensuring that the agent concentration is always in a state that can efficiently remove oil stains and fully remove the oil stains attached to the screws.

[0022] The pre-degreased screws are sent into the first clean water tank 2 and rinsed with clean water to remove the pre-degreased agent and the detached oil stains adhering to the screw surface, so as to avoid residual agent affecting the effect of subsequent activation process.

[0023] After the screws enter the activation tank 3, the PLC controller controls the first flow metering valve 33 at the outlet of the activator storage tank 31 and the second flow metering valve 34 at the outlet of the nitric acid storage tank 32 to input the activator and nitric acid into the tank at a ratio of 1:0.8. Simultaneously, the PLC controller starts the metering pump 36, which quantitatively extracts gloss agent from the gloss agent storage tank 35 through the addition pipeline and delivers it to the activation tank 3. During this process, the ultrasonic generator 51 starts, driving the ultrasonic transducer 52 on the side wall of the tank to work. With the help of ultrasonic impact, the activator, nitric acid, and gloss agent fully act on the screw surface, completing the activation treatment, protecting the screw surface gloss, and thoroughly cleaning residual impurities.

[0024] After activation treatment, the screws enter the second clean water tank 4 and are rinsed thoroughly with clean water again to remove various chemicals such as activators, nitric acid, and gloss agents remaining on the surface of the screws, ultimately resulting in clean screws that meet quality standards.

[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
