Description

Technical Field

[0001] This utility model relates to the field of pickling tank technology, and in particular to an automatic opening and closing cover for a pickling tank. Background Technology

[0002] A pickling tank is a piece of equipment used for chemical treatment. It mainly uses chemical agents to soak metal parts and react with rust, scale and other impurities on the metal surface, thereby removing rust, scale and other impurities from the surface between the metal parts.

[0003] Chinese patent discloses an automatic opening and closing cover for a pickling tank (authorization announcement number CN219508029U). When the opening and closing cover and the extension cover are opened, they will cover the pickling tank. When the opening and closing cover and the extension cover are closed, they will be retracted into the interior of the pickling tank. At the same time, the extension cover is hinged to the opening and closing cover, so that the operator can fold the extension cover.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the existing automatic opening and closing cover of the pickling tank does not effectively fix the cover after the pickling tank is covered. During the pickling process, waste gas is generated, which increases the internal pressure of the pickling tank and may push the cover upward, causing waste gas leakage, polluting the environment, and potentially harming the health of nearby workers. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology does not effectively fix the cover plate, which generates waste gas during the pickling process, causing the internal pressure of the pickling tank to increase, which may push the cover plate upward, resulting in waste gas leakage and environmental pollution. To address this, we propose an automatic opening and closing cover for pickling tanks.

[0006] To achieve the above objectives, this application adopts the following technical solution: an automatic opening and closing cover for an acid pickling tank, comprising an acid pickling tank body, a cover plate attached to the top of the acid pickling tank body, slots on both sides of the cover plate, a gantry frame fixedly connected to the top of the acid pickling tank body, the interior of the slots slidingly connected to the surface of the gantry frame, a motor mounted on the top of the cover plate, a gear fixedly connected to the output end of the motor, a toothed plate fixedly fixed to the top of the cover plate, a control cabinet mounted on one side of the acid pickling tank body, a fixing block fixedly connected to one side of the cover plate, a hollow block fixedly connected to one side of the acid pickling tank body, a connecting plate slidingly connected to the interior of the hollow block, a limit rod fixedly connected to one side of the connecting plate, and the surface of the limit rod slidingly connected to the interior of the fixing block.

[0007] Preferably, two thrust springs are fixedly connected to one side of the connecting plate, and the other end of the thrust springs is fixedly connected to one side of the hollow block.

[0008] Preferably, an elliptical block is rotatably connected inside the hollow block, and a connecting rod is fixedly connected to one side of the elliptical block, with a knob installed at one end of the connecting rod.

[0009] Preferably, a telescopic rod is slidably connected inside the connecting rod, one end of the telescopic rod is fixedly connected to one side of the knob, a limit hole is opened on one side of the hollow block, and a limit block is fixedly connected to one side of the knob.

[0010] Preferably, the connecting rod has limit grooves on both sides inside, and the telescopic rod has limit sliders fixedly connected to both sides.

[0011] Preferably, one end of the telescopic rod is fixedly connected to a tension spring, and the other end of the tension spring is fixedly connected to one side of the inside of the connecting rod.

[0012] Preferably, a placement groove is provided on both sides inside the groove, and a pulley is installed inside the placement groove.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, the motor is controlled to rotate in reverse by the control cabinet, causing the cover plate to move downward and seal the top of the pickling tank body. The moving limit rod enters the interior of the fixing block to limit the cover plate and prevent the chemical reaction inside the pickling tank body from generating gas. The cover plate is then pushed upward, causing a gap between the top of the pickling tank body and the bottom of the cover plate, resulting in gas leakage and environmental pollution.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: an automatic opening and closing cover for an acid pickling tank, including an acid pickling tank body 1, a cover plate 2 attached to the top of the acid pickling tank body 1, slots 22 on both sides of the cover plate 2, a gantry frame 3 fixedly connected to the top of the acid pickling tank body 1, the interior of the slots 22 slidingly connected to the surface of the gantry frame 3, a motor 4 installed on the top of the cover plate 2, a gear 5 fixedly connected to the output end of the motor 4, a toothed plate 6 fixedly fixed to the top of the cover plate 2, a control cabinet 7 installed on one side of the acid pickling tank body 1, a fixing block 8 fixedly connected to one side of the cover plate 2, a hollow block 9 fixedly connected to one side of the acid pickling tank body 1, a connecting plate 10 slidably connected inside the hollow block 9, a limit rod 11 fixedly connected to one side of the connecting plate 10, and the surface of the limit rod 11... The pickling tank body 1 is slidably connected to the inside of the fixed block 8. When the user needs to open the pickling tank body 1 to add materials, the limit rod 11 is moved to disengage from the inside of the fixed block 8, releasing the limit on the cover plate 2. The motor 4 is controlled by the control cabinet 7 to rotate, driving the cover plate 2 to move upward, opening the top of the pickling tank body 1. After the materials are added, the motor 4 is controlled by the control cabinet 7 to rotate in the opposite direction, driving the cover plate 2 to move downward, closing the top of the pickling tank body 1. The limit rod 11 is moved into the inside of the fixed block 8 to limit the cover plate 2, preventing the chemical reaction inside the pickling tank body 1 from generating gas. Pushing the cover plate 2 upward creates a gap between the top of the pickling tank body 1 and the bottom of the cover plate 2, causing internal gas leakage and environmental pollution.

[0023] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: two thrust springs 12 are fixedly connected to one side of the connecting plate 10, and the other end of the thrust spring 12 is fixedly connected to one side of the interior of the hollow block 9. An elliptical block 13 is rotatably connected inside the hollow block 9. A connecting rod 14 is fixedly connected to one side of the elliptical block 13. A knob 15 is installed at one end of the connecting rod 14. When the user needs to open the cover plate 2, by rotating the knob 15, the elliptical block 13 is rotated, releasing the restriction on the connecting plate 10. Under the thrust of the thrust springs 12, the connecting plate 10 is pushed to move, causing the limiting rod 11 to disengage from the interior of the fixed block 8, releasing the restriction on the cover plate 2, and allowing the cover plate 2 to move upward.

[0024] Reference Figure 4 As shown in this embodiment: a telescopic rod 16 is slidably connected inside the connecting rod 14. One end of the telescopic rod 16 is fixedly connected to one side of the knob 15. A limit hole 17 is opened on one side of the hollow block 9. A limit block 18 is fixedly connected to one side of the knob 15. When the user needs to open the cover plate 2, he pulls the knob 15, which drives the limit block 18 to disengage from the inside of the limit hole 17, thus releasing the limit on the knob 15. Rotating the knob 15 releases the limit on the connecting plate 10. Under the thrust of the thrust spring 12, the connecting plate 10 is pushed to move, causing the limit rod 11 to disengage from the inside of the fixed block 8, thus releasing the limit on the cover plate 2. By inserting the limit block 18 into the inside of the limit hole 17, the knob 15 can be prevented from rotating due to vibration during equipment operation.

[0025] Reference Figure 4 As shown in this embodiment: both sides of the connecting rod 14 are provided with limiting grooves 19, and both sides of the telescopic rod 16 are fixedly connected with limiting sliders 20. When the user pulls the knob 15, the limiting sliders 20 on both sides of the telescopic rod 16 slide inside the limiting grooves 19 to limit the movement of the telescopic rod 16 and prevent the telescopic rod 16 from leaving the interior of the connecting rod 14.

[0026] Reference Figure 4 As shown in this embodiment: one end of the telescopic rod 16 is fixedly connected to a tension spring 21, and the other end of the tension spring 21 is fixedly connected to one side of the inside of the connecting rod 14. By installing the tension spring 21 at the rear end of the telescopic rod 16, a continuous tension can be released on the telescopic rod 16 to prevent the knob 15 from being vibrated and moving outward, causing the limiting block 18 to disengage from the inside of the limiting hole 17.

[0027] Reference Figure 5As shown in this embodiment: both sides of the slot 22 are provided with placement slots 23, and pulleys 24 are installed inside the placement slots 23. When the user starts the motor 4 to drive the cover plate 2 to move up and down, the pulleys 24 installed on both sides of the cover plate 2 follow the movement of the cover plate 2 and rotate on the surface of the gantry 3, reducing the friction between the cover plate 2 and the gantry 3, avoiding wear at the contact point between the cover plate 2 and the gantry 3, and increasing the service life of the equipment.

[0028] Working principle: When the user needs to open the pickling tank body 1 to add materials, the limit rod 11 is moved to disengage from the fixed block 8, releasing the restriction on the cover plate 2. The control cabinet 7 controls the motor 4 to rotate, causing the cover plate 2 to move upward, opening the top of the pickling tank body 1. After materials are added, the control cabinet 7 controls the motor 4 to rotate in the opposite direction, causing the cover plate 2 to move downward, closing the top of the pickling tank body 1. The limit rod 11 is then moved into the fixed block 8 to restrict the cover plate 2. To prevent the chemical reaction inside the pickling tank body 1 from generating gas, push the cover plate 2 upwards, creating a gap between the top of the pickling tank body 1 and the bottom of the cover plate 2. When it is necessary to open the cover plate 2, rotate the knob 15 to rotate the elliptical block 13, releasing the restriction on the connecting plate 10. Under the thrust of the thrust spring 12, push the connecting plate 10 to move, causing the limiting rod 11 to disengage from the inside of the fixing block 8, releasing the restriction on the cover plate 2, allowing the cover plate 2 to move upwards. When it is necessary to open the cover plate 2, pull the knob 15 to rotate the limiting rod 11. The positioning block 18 disengages from the interior of the limiting hole 17, releasing the restriction on the knob 15. Rotating the knob 15 releases the restriction on the connecting plate 10. Under the thrust of the thrust spring 12, the connecting plate 10 is moved, causing the limiting rod 11 to disengage from the interior of the fixing block 8, releasing the restriction on the cover plate 2. By inserting the limiting block 18 into the interior of the limiting hole 17, the knob 15 can be prevented from rotating due to vibrations during equipment operation. During the pulling of the knob 15, the limiting sliders 20 on both sides of the telescopic rod 16 slide within the limiting groove 19. The movement of the telescopic rod 16 is limited to prevent it from disengaging from the interior of the connecting rod 14. By installing a tension spring 21 at the rear end of the telescopic rod 16, a continuous tension can be released on the telescopic rod 16 to prevent the knob 15 from being vibrated and moving outward, causing the limiting block 18 to disengage from the interior of the limiting hole 17. During the process of the start motor 4 driving the cover plate 2 to move up and down, the pulleys 24 installed on both sides of the cover plate 2 follow the movement of the cover plate 2 and rotate on the surface of the gantry 3, reducing the friction between the cover plate 2 and the gantry 3.
