Description

Technical Field

[0001] This utility model relates to the field of metal cleaning agent technology, and in particular to a mixing and stirring device for metal cleaning agents. Background Technology

[0002] With the development of modern industry, metal products are increasingly widely used in various fields. However, after metal processing, such as cutting, welding, and forming, impurities such as oil, iron filings, and oxides often remain on the metal surface. This not only affects the appearance quality of metal products, but may also have an adverse effect on subsequent processing steps or the performance of the products. Therefore, metal cleaning has become an indispensable part of metal processing.

[0003] For example, Chinese utility model patent (CN215387726U) discloses a membrane cleaning agent production device with efficient mixing and stirring function, including a settling shell and a fixing plate. A stirring shell is installed on the top of the settling shell, and a protective shell is installed on the inner wall of the top of the settling shell. An electric motor is installed inside the protective shell by rivets. A rotating rod is installed at the output end of the electric motor. A cutting head is installed on the outer surface of the rotating rod, and a stirring head is installed on the outer surface of the rotating rod. A large-pore sponge layer is installed inside the settling shell by fixing bolts. This utility model uses a settling shell with a stirring head and a large-pore sponge layer. The stirring head stirs the inside of the membrane cleaning agent, causing the bubbles deposited inside the membrane cleaning agent to rise to the top of the membrane cleaning agent. When the membrane cleaning agent seeps downward through the holes at the top of the large-pore sponge layer under the action of gravity, the bubbles at the top of the membrane cleaning agent are separated at the top of the large-pore sponge layer, thus completing the removal of bubbles from the membrane cleaning agent.

[0004] However, when the inventors implemented this device, they found the following defects: the raw materials of the cleaning agent usually include water, surfactants, alkaline substances, chelating agents, corrosion inhibitors and other additives. If the alkaline substances or corrosion inhibitors are not fully dissolved during the preparation process, a small amount of particles may remain in the cleaning solution or even block the macroporous sponge layer, affecting the subsequent cleaning effect. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0047] As described in the background section, the components of cleaning agents typically include water, surfactants, alkaline substances, chelating agents, corrosion inhibitors, and other additives. If the alkaline substances or corrosion inhibitors are not fully dissolved during the preparation process, a small amount of particles may remain in the cleaning solution or even clog the macroporous sponge layer, affecting the subsequent cleaning effect. To solve this technical problem, this invention provides a mixing and stirring device for metal cleaning agents.

[0048] For details, please refer to Figure 1-5 The mixing and stirring device specifically includes:

[0049] The system includes a support frame 1 and a mixing tank 2. A filter cotton 15 is installed on the inner bottom surface of the mixing tank 2. A sealing cover 3 is fixedly installed on the support frame 1. A stirring motor 4 is fixedly installed inside the sealing cover 3. The output end of the stirring motor 4 is connected to a stirring element 5. An annular pipe 6 is fixedly installed on the sealing cover 3 and connected to a water source. A support ring 7 is fixedly installed inside the sealing cover 3. Symmetrically arranged water outlet pipes 8 are installed on the inner wall of the support ring 7.

[0052] Among them, the annular pipe 6 is fixedly connected to the water outlet pipe 8 and the hollow rod 11 with a conveying hose 16.

[0053] The mixing and stirring device for metal cleaning agents provided by this utility model involves adding the materials to be mixed into the mixing tank 2, closing and fixing the sealing cover 3 to ensure the device is sealed, starting the stirring motor 4 to drive the stirring component 5 to rotate, and stirring the materials.

Filter cotton 15 is installed on the inner bottom surface of the mixing tank 2. Rollers are also installed on the outer bottom surface of the mixing tank 2 for easy movement. A sealing cover 3 is fixedly installed on the support frame 1. The sealing cover 3 has a feed port and a feed pipe 301 adapted to the feed port. A stirring motor 4 is fixedly installed inside the sealing cover 3. The output end of the stirring motor 4 is connected to a stirring element 5, which is responsible for stirring the material. An annular pipe 6 is fixedly installed on the sealing cover 3 and connected to a water source. A support ring 7 is fixedly installed inside the sealing cover 3. Symmetrically arranged water outlet pipes 8 are installed on the inner wall of the support ring 7. Spray nozzles 9 are fixedly installed on the water outlet pipes 8. The device also includes:

[0058] The bushing 10 is coaxial with the support ring 7, and its outer circular surface is fixedly connected to the water outlet pipe 8. An elastic element 13 is provided inside the bushing 10, and the two ends of the elastic element 13 are respectively connected to the output end of the stirring motor 4 and the stirring element 5.

[0059] A hollow rod 11 is fixedly installed between the support ring 7 and the bushing 10 and passes through the inside of the bushing 10. A push rod 12 is slidably installed inside the hollow rod 11. The push rod 12 has a piston part 1201. A retaining ring 1101 is inside the hollow rod 11. A first spring 1202 is sleeved on the push rod 12. The two ends of the first spring 1202 are fixedly connected to the piston part 1201 and the retaining ring 1101 respectively. A pressure rod 1304 that abuts against the push rod 12 is fixedly installed on the elastic member 13.

[0060] Among them, the annular pipe 6 is fixedly connected to the water outlet pipe 8 and the hollow rod 11 with a conveying hose 16.

[0061] Please refer to Figure 5 The elastic element 13 includes a slip ring 1301, which is installed inside the bushing 10. A second spring 1302 is fixedly connected between the slip ring 1301 and the inner bottom surface of the bushing 10 to provide elastic support. A conical block 1303 is rotatably mounted on the slip ring 1301. The output end of the stirring motor 4 is slidably connected to the conical block 1303. The stirring element 5 is fixedly connected to the conical block 1303.

[0062] A support seat 1305 is fixedly installed on the inner wall of the bushing 10. A pressure rod 1304 is slidably installed in the support seat 1305. A push block 1306 is fixedly installed at the end of the pressure rod 1304 away from the push rod 12. A tension spring 1307 is sleeved on the pressure rod 1304. The two ends of the tension spring 1307 abut against the support seat 1305 and the push block 1306 respectively.

[0063] The mixing and stirring device for the metal cleaning agent provided in this embodiment adds the materials to be mixed into the mixing tank 2 through the feed pipe 301. The sealing cap 3 is closed and secured, ensuring the entire device is sealed. The stirring motor 4 is started, driving the stirring element 5 to rotate and thoroughly mix the materials. During this process, the stirring element 5 does not contact the filter cotton 15 in its original state to avoid wear and contamination. The valve 202 is opened, and the mixed materials are discharged through the discharge pipe 201. The filter cotton 15 intercepts particulate matter in the materials, keeping the cleaning agent clean. Water is supplied through the annular pipe 6, flowing through the conveying hose 16 into the water outlet pipe 8, and then evenly sprayed into the mixing tank 2 by the nozzle 9 to assist in cleaning. Simultaneously, water enters the hollow rod 11, using water pressure to push the push rod 12 forward, which in turn pushes the pressure rod 1304, causing the stirring element 5 to move downwards and contact the filter cotton 15, cleaning the residue adhering to the surface of the filter cotton 15 for easy reuse. Example

[0064] The mixing and stirring device provided in Example 1 has been further optimized, specifically, as follows: Figure 3 As shown, the stirring component 5 includes a rotating shaft 501, frame-shaped blades 502 are fixedly mounted on the rotating shaft 501 at equal intervals, and a crushing wheel 503 is fixedly mounted on the rotating shaft 501.

[0065] Through the above structural design, the frame-shaped paddle 502 helps to push materials from different parts of the barrel towards the center or edge, promoting full contact and mixing between materials, and increasing the contact area between the materials and the paddle, thus improving mixing efficiency. The crushing wheel 503, fixedly installed on the rotating shaft 501, is mainly used to process larger particles or lumps of materials. While stirring, it performs preliminary crushing of the materials, ensuring that all materials are uniformly mixed and reach the required fineness. After completing the stirring task, water is supplied through the annular pipe 6, and the water flows through the conveying hose 16 into the outlet pipe 8, and is sprayed into the interior of the mixing barrel 2 by the nozzle 9 for cleaning. At the same time, the push rod 12 pushes the pressure rod 1304 to move the stirring element 5 down and into contact with the filter cotton 15. The frame-shaped paddle 502 and the crushing wheel 503 remove residues from the surface of the filter cotton 15, ensuring the cleanliness of the equipment and facilitating subsequent operations. Example

[0066] The mixing and stirring apparatus provided in Example 1 or 2 can be further optimized, such as... Figure 1-3 As shown, the support frame 1 includes a base 101 and a drive seat 102, and a sealing cover 3 is fixedly installed on the drive seat 102; wherein, an actuator 103 is installed between the base 101 and the drive seat 102 for controlling the lifting and lowering of the drive seat 102.

[0067] It should be noted that the actuator 103 is preferably a cylinder, which has a fast response to operating commands and facilitates the adjustment of the height and position of the sealing cover 3 and its connecting parts.

[0068] In practice, the actuator 103 lifts the drive base 102 along with the sealing cover 3 to facilitate loading the materials to be mixed into the mixing tank 2. After all materials have been added, the drive base 102 is lowered to tightly close the sealing cover 3 in the mixing tank 2, ensuring no leakage. Then, the stirring motor 4 is started to stir the materials. After stirring is complete, the position of the sealing cover 3 can be easily adjusted using the actuator 103 to facilitate subsequent maintenance operations such as cleaning or replacing the filter cotton 15. Example

[0069] The mixing and stirring apparatus provided in the above embodiments is further optimized, such as... Figure 1 As shown, the support frame 1 also includes a control board, and a temperature probe 504 is installed on the rotating shaft 501. The temperature probe 504 is wirelessly connected to the control board.

[0070] With the above-mentioned structure, during the mixing process, the temperature probe 504 continuously monitors the material temperature and sends the data to the control board wirelessly. If the temperature exceeds the preset range, the control board can take immediate measures, such as adjusting the mixing speed to maintain the optimal working temperature. Example

[0071] The mixing and stirring apparatus provided in the above embodiments is further optimized, such as... Figure 1-4 As shown, a positioning sensor 104 is fixedly installed on the base 101, and a limiting block 105 that abuts against the positioning sensor 104 is fixedly installed on the mixing tank 2.

[0072] Loading stage: Before adding the materials to be mixed into the mixing tank 2, it is necessary to ensure that the mixing tank 2 is accurately placed on the support frame 1. At this time, the limit block 105 should be aligned and in contact with the positioning sensor 104.

[0073] Position confirmation: Once the mixing tank 2 is correctly placed, the limit block 105 will trigger the positioning sensor 104 to send a signal to the control system, indicating that the mixing tank 2 has been positioned and the next operation can be carried out, such as closing the sealing cover 3 and starting the mixing motor 4.

[0074] Safety assurance during operation: If the mixing tank 2 is displaced for some reason during the mixing process, and the relative position between the limit block 105 and the positioning sensor 104 changes, the system can immediately detect this situation and take corresponding measures, such as stopping the mixing motor 4, to prevent potential safety hazards or equipment damage.

[0075] Unloading and Maintenance: After mixing is complete, valve 202 is opened to discharge the material through discharge pipe 201. During this process, limit block 105 continues to maintain contact with positioning sensor 104 to ensure the safety and stability of the entire unloading process. Furthermore, this system can also be used to quickly check whether the mixing tank 2 has been correctly removed or reinstalled during equipment maintenance or cleaning.

[0076] The automatic column-passing device provided by this utility model is used as follows:

[0077] The mixing tank 2 is pushed into the support frame 1. At this time, the limit block 105 is aligned and in contact with the positioning sensor 104, and a signal is sent to the control system to indicate that the mixing tank 2 is in place. The actuator 103 is used to lift the drive seat 102 together with the sealing cover 3 so that the materials to be mixed can be added into the mixing tank 2 through the feed pipe 301. After all the materials have been added, the drive seat 102 is lowered so that the sealing cover 3 tightly closes the mixing tank 2 to ensure that there is no leakage. The stirring motor 4 is started, which drives the frame blade 502 and the crushing wheel 503 on the rotating shaft 501 to fully stir and initially crush the materials. The temperature probe 504 monitors the material temperature in real time and sends the data to the control board wirelessly. If the temperature exceeds the preset range, the control panel can adjust the stirring speed or take other measures to maintain the optimal working temperature. After stirring is completed, the valve 202 is opened to discharge the mixed material through the discharge pipe 201. The filter cotton 15 intercepts particulate matter in the material to keep the cleaning agent clean. Water is supplied through the ring pipe 6, and the water flows through the conveying hose 16 into the water outlet pipe 8. It is then evenly sprayed into the interior of the mixing tank 2 by the nozzle 9 to assist in cleaning. At the same time, the push rod 12 inside the hollow rod 11 moves forward using water pressure, pushing the pressure rod 1304 to make the stirring piece 5 move down and contact the filter cotton 15, cleaning the residue attached to the surface of the filter cotton 15 for reuse. During the entire operation, if the mixing tank 2 is displaced, the positioning sensor 104 will detect the change in position of the limit block 105 and immediately take corresponding measures, such as stopping the stirring motor 4, to prevent safety hazards or equipment damage.
