Description

Technical Field

[0001] The present application relates to the technical field of pickling equipment maintenance, and in particular to a cleaning device for a pickling tank. Background Art

[0002] Pickling is a metal surface treatment process, mainly used to remove scale, rust, dirt, etc. on the metal surface to improve the surface quality of the metal and enhance its corrosion resistance and decorative properties. The pickling tank is used to hold the aqueous solution during the pickling process and has good alkali resistance, acid resistance, high temperature resistance and corrosion resistance.

[0003] During the pickling process, the pickling liquid reacts with the rust, oxide layer, dirt, etc. on the surface of the metal parts to generate solid impurities. These impurities accumulate at the bottom of the pickling tank for a long time to form a film. The impurity film attached to the bottom wall of the pickling tank is difficult to remove by simple water washing, so when cleaning the pickling tank, it is necessary to scrub the bottom wall of the pickling tank; because the heated pickling liquid will produce acid mist. In order to ensure the safety and environmental protection of the production environment, an outer cover and a partial exhaust mask device are usually installed on the outside of the pickling tank. When cleaning this pickling tank, in order to reduce the risk of residual acidic gas in the tank escaping to the outside in large quantities, the outer cover or the partial exhaust mask device can only be pushed a short distance to leave a narrow cleaning port or only part of the structure is disassembled as a cleaning port. The outer cover or partial exhaust mask device of the pickling tank will prevent workers from scrubbing the bottom wall of the pickling tank, and the cleaning process will become cumbersome and difficult to clean. Summary of the invention

[0004] The purpose of the present application is to provide a cleaning device for a pickling tank in order to solve the above-mentioned problems, so as to reduce the difficulty of cleaning the pickling tank and improve the above-mentioned problems.

[0005] This application is achieved through the following technical solutions:

[0006] In some embodiments, the present application provides a cleaning device for a pickling tank, the cleaning device for the pickling tank comprising a shell, a cleaning belt, a recovery mechanism, a conveying mechanism, a walking mechanism, a control module and a limiting mechanism; the shell has a first opening; the cleaning belt is located on the inner side of the shell, at least part of the cleaning belt extends out of the shell from the first opening, and the cleaning belt extending out of the shell is wound on a roller; the recovery mechanism and the conveying mechanism are both arranged on the inner side of the shell, the conveying mechanism is used to send the cleaning belt out of the shell from the first opening, and the recovery mechanism is used to retract the cleaning belt into the shell; the walking mechanism is used to drive the shell to move along the bottom wall of the pickling tank, and the control module is used to control the walking mechanism to move or stop; the limiting mechanism is arranged on the outer side of the shell, the limiting mechanism is hinged to the roller, and is used to pull the roller so that the cleaning belt wound on the roller is in contact with the bottom wall of the pickling tank; wherein a cleaning drive is provided at the connection between the limiting mechanism and the roller, and the cleaning drive is used to drive the roller to rotate so as to wind the cleaning belt around the roller.

[0007] In the technical solution of the embodiment of the present application, part of the cleaning tape extends out of the shell from the first opening, and the cleaning tape extending out of the shell is wound around the roller; the recovery mechanism and the conveying mechanism are both arranged on the inner side of the shell, and one end of the cleaning tape located on the inner side of the shell is connected to the recovery mechanism, thereby reducing the risk of the cleaning tape detaching from the recovery mechanism by itself; the conveying mechanism is used to send the cleaning tape out of the shell from the first opening, and the recovery mechanism is used to retract the cleaning tape into the shell; the cleaning drive member drives the roller to rotate to reel the cleaning tape sent out of the shell onto itself, and when the recovery mechanism retracts the cleaning tape into the shell, the cleaning belt pulls the roller to rotate, so that the cleaning belt is always in a stretched state; during the specific use of the cleaning device for the pickling tank provided by the present application, the acidic liquid in the pickling tank is discharged, and the pickling tank is first cleaned. The cleaning belt is then washed with water for the first time, and then clean water is added to the pickling tank. The operator places the cleaning device provided by the present application on the inner side of the pickling tank, and the walking mechanism moves along the bottom wall of the pickling tank under the control of the control module. During the movement of the cleaning device provided by the present application, the conveying mechanism and the recovery mechanism are alternately opened, the conveying mechanism is opened to send the cleaning belt out of the shell, the cleaning drive member rotates to wind the cleaning belt onto the roller, the recovery mechanism is opened to pull the cleaning belt and retract it to the inner side of the shell, and the limiting mechanism pulls the roller toward the bottom wall of the pickling tank so that the cleaning belt wound on the roller is in close contact with the bottom wall of the pickling tank to scrub it. The speed at which the cleaning belt is sent out and retracted into the shell is faster than the moving speed of the cleaning device, so that the friction between the cleaning belt and the bottom wall of the pickling tank is generated. The friction force is a large sliding friction force, thereby scrubbing the impurity film attached to the bottom wall of the pickling tank, and scrubbing the impurity film into deposits accumulated at the bottom of the pickling tank or residues floating in the liquid in the pickling tank. The local area of ​​the bottom wall of the pickling tank can be scrubbed repeatedly according to the attachment situation of the impurity film. After the scrubbing is completed, the cleaning device is taken out of the pickling tank, and the pickling tank is washed with water again. The deposits accumulated at the bottom of the pickling tank or the residues floating in the liquid in the pickling tank are washed away by the water flow, so that the pickling tank becomes clean and convenient for subsequent use. The cleaning device for the pickling tank provided in the present application can be placed in the pickling tank and moved to the pickling tank covered by the outer cover or the local exhaust shield device when facing the pickling tank with the outer cover or the local exhaust shield device. The area blocked by the row shielding device is scrubbed to complete the cleaning of the area. The cleaning process is simple and fast, eliminating the trouble of disassembling or moving the entire outer cover or partial row shielding device, and avoiding safety accidents such as slipping or collision when workers enter the area blocked by the outer cover or partial row shielding device for cleaning. In addition, although it has been washed once, the liquid in the pickling tank may still be mixed with some acidic liquid, which has certain corrosiveness. Cleaning the pickling tank by the cleaning device for the pickling tank provided by the present application also avoids workers from long-term contact with potentially corrosive liquids, reduces the risk of workers' clothes, skin, etc. being corroded and damaged by liquids, and reduces labor costs by replacing manual labor with machinery.

[0008] In some embodiments, a pair of guide members are also provided on the inner side of the shell, and the cleaning belt passes through the pair of guide members. The space enclosed by the pair of guide members and the shell has two opposite openings, one opening faces the first opening, and the other opening faces the conveying mechanism.

The pair of guide members guide the moving path of the cleaning belt between the conveying mechanism and the first opening, thereby reducing the risk of the cleaning belt being scratched or collided with other components or the outer shell on the inner side of the outer shell, causing damage to the cleaning belt or other components; on the other hand.

[0010] In some embodiments, a scraper is disposed at one end of the guide member close to the first opening, and two scrapers on the two guide members are in contact with two opposite surfaces of the cleaning belt.

The scraper can scrape off the film fragments or other solid impurities that may be adhered to the cleaning belt when the recovery mechanism retracts the cleaning belt into the inner side of the outer shell, thereby preventing these film fragments or other solid impurities from adhering to the cleaning belt for a long time, corroding or scratching the surface of the cleaning belt, and extending the service life of the cleaning belt.

[0012] In some embodiments, the shell includes a first shell, a second shell and a third shell, the recovery mechanism is arranged in the first shell, the conveying mechanism is arranged in the second shell, the first opening is arranged in the third shell, the first shell is connected with the second shell, the second shell is connected with the third shell, and the part of the cleaning tape located on the inner side of the third shell is supported by the guide member and is in a suspended state.

[0014] In some embodiments, a first driving member and a plurality of limiting wheels are also provided in the third shell. The first driving member is fixedly connected to the third shell. The guide member of the first driving member rises along its own length direction so that the guide member is higher than the liquid level of the liquid in the pickling tank; the plurality of limiting wheels are rotatably connected to the third shell. The plurality of limiting wheels are respectively in contact with a pair of guide members facing away from the surface of the cleaning belt, and the limiting wheels rotate with the movement of the guide members.

[0015] In the technical solution of the embodiment of the present application, the first driving member guide rises along its own length direction so that the guide is higher than the liquid level of the liquid in the pickling tank, thereby preventing the liquid in the pickling tank from carrying the suspended impurities scrubbed off from entering between the two guide members and adhering to the cleaning belt, thereby reducing the risk of the cleaning belt being corroded or scratched by impurities during its movement inside the shell; multiple limiting wheels are rotatably connected to the third shell, and the multiple limiting wheels are respectively in contact with the surface of a pair of guide members facing away from the cleaning belt.

[0016] In some embodiments, the first shell is provided with a first sensor, which is used to detect the liquid level height of the liquid in the pickling tank. The first driving member drives the guide member to rise based on the liquid level height information in the pickling tank so that the guide member is higher than the liquid level in the pickling tank.

[0019] In the technical solution of the embodiment of the present application, the recovery wheel is rotatably arranged in the first shell, and the outer peripheral surface of the recovery wheel is provided with a groove for connecting with the second end, so that the cleaning tape wound on the recovery wheel and close to the groove fits with the recovery wheel, thereby improving the integrity of the recovery wheel and the cleaning tape wound on the recovery wheel. The second driving member drives the recovery wheel to rotate to wind the cleaning tape onto the recovery wheel, reducing the space occupied by the cleaning tape when stored inside the outer shell, so that the overall size of the cleaning device for the pickling tank provided by the present application is smaller, which is convenient for workers to move it.

[0020] In some embodiments, the recovery mechanism further includes a cleaning component, which includes a plurality of water spray nozzles disposed on the first shell, the water spray nozzles being used to spray water onto the cleaning belt wound onto the recovery wheel, and the first shell is also provided with a water outlet.

[0021] In the technical solution of the embodiment of the present application, multiple water nozzles are arranged on the first shell, and the water nozzles are used to spray water onto the cleaning belt wound around the recovery wheel. On the one hand, impurities that may be on the cleaning belt are cleaned, and on the other hand, the water nozzles are used to clean the acidic substances that may be attached to the cleaning belt, thereby reducing the risk of the cleaning belt wound around the recovery wheel being damaged by impurities or corroded by acidic substances, thereby extending the service life of the cleaning belt. The first shell is also provided with a water outlet, and the liquid used to clean the cleaning belt can be discharged in time through the water outlet.

[0022] In some embodiments, the conveying mechanism includes a conveying wheel, a third driving member, a pressure wheel and a fourth driving member.

[0041] According to some embodiments of the present application, optionally, Figure 1 to Figure 6 As shown, the application provides a cleaning device for a pickling tank, which includes a shell 1, a cleaning belt 2, a recovery mechanism 3, a conveying mechanism 4, a walking mechanism 15, a control module and a limiting mechanism 5; the shell 1 has a first opening 10; the cleaning belt 2 is located inside the shell 1, at least part of the cleaning belt 2 extends out of the shell 1 from the first opening 10, and the cleaning belt 2 extending out of the shell 1 is wound on a roller 20; the recovery mechanism 3 and the conveying mechanism 4 are both arranged on the inside of the shell 1, and the conveying mechanism 4 is used to send the cleaning belt 2 out of the first opening 10 The outer shell 1 and the recovery mechanism 3 are used to recover the cleaning tape 2 into the outer shell 1; the walking mechanism 15 is used to drive the outer shell 1 to move along the bottom wall of the pickling tank, and the control module is used to control the walking mechanism 15 to move or stop; the limiting mechanism 5 is arranged on the outer side of the outer shell 1, and the limiting mechanism 5 is hinged to the roller 20, and is used to pull the roller 20 so that the cleaning tape 2 wound on the roller 20 is in contact with the bottom wall of the pickling tank; wherein, a cleaning drive is arranged at the connection between the limiting mechanism 5 and the roller 20, and the cleaning drive is used to drive the roller 20 to rotate so as to wind the cleaning tape 2 around the roller 20.

[0042] The material of the cleaning belt 2 can be ultra-high molecular weight polyethylene (UHMWPE), which is a thermoplastic engineering plastic with excellent comprehensive properties, high wear resistance, good chemical corrosion resistance and low water absorption, so that the cleaning belt 2 can have a long service life under the strong corrosion and high wear conditions of the pickling tank.

[0043] A portion of the cleaning tape 2 extends out of the first opening 10 from the housing 1, and the cleaning tape 2 extending out of the housing 1 is wound around the roller 20; the recovery mechanism 3 and the conveying mechanism 4 are both arranged on the inner side of the housing 1, and one end of the cleaning tape 2 located on the inner side of the housing 1 is connected to the recovery mechanism 3, so as to reduce the risk of the cleaning tape 2 detaching from the recovery mechanism 3 by itself; the conveying mechanism 4 is used to send the cleaning tape 2 out of the housing 1 from the first opening 10, and the recovery mechanism 3 is used to retract the cleaning tape 2 into the housing 1; the cleaning drive member drives the roller 20 to rotate to reel the cleaning tape 2 sent out of the housing 1 onto itself; when the recovery mechanism 3 retracts the cleaning tape 2 into the housing 1, the cleaning tape 2 pulls the roller 20 to rotate, so that the cleaning tape 2 is always in a stretched state; During the specific use of the cleaning device for the pickling tank provided in the application, the acidic liquid in the pickling tank is drained, the pickling tank is first washed with water, and then clean water is added to the pickling tank. The operator places the cleaning device provided in the application on the inner side of the pickling tank, and the walking mechanism 15 moves along the bottom wall of the pickling tank under the control of the control module.

[0050] A scraper 110 is provided at one end of the guide member 11 close to the first opening 10. The two scrapers 110 on the two guide members 11 are in contact with two opposite surfaces of the cleaning belt 2.

[0053] The third shell 14 can rotate around the connection between itself and the second shell 13, which can meet various usage requirements, or can scrub a local area without moving the cleaning device to enhance the cleaning effect on the bottom wall of the pickling tank.

[0054] The recovery mechanism 3 is arranged on the first shell 12, the conveying mechanism 4 is arranged on the second shell 13, and the first opening 10 is arranged on the third shell 14. The first shell 12 is connected to the second shell 13. The recovery mechanism 3 and the conveying mechanism 4 are arranged separately to avoid the two from affecting each other outside the cleaning belt 2. The second shell 13 is connected to the third shell 14.
