Description

Technical Field

[0001] This utility model belongs to the field of damper valve plate corrosion treatment technology, and in particular relates to a damper valve plate corrosion treatment device. Background Technology

[0002] Corrosion treatment of damper valve plates mainly includes surface protection and functional enhancement, with the aim of extending service life and maintaining stable performance. It is necessary to consider the valve plate material (e.g., steel, aluminum, composite materials), the operating environment (corrosive media, temperature, pressure), and performance requirements (corrosion resistance, wear resistance, sealing performance). Based on the corrosion mechanism and performance requirements, corrosion treatment can be divided into three categories: surface protection, functional enhancement, and repair / regeneration. Surface protection, by forming an isolation layer or passivation film, blocks the contact between the medium and the substrate, and is suitable for valve plates that are not corroded or only slightly corroded. Functional enhancement is for valve plates that are worn or have failed sealing; it improves friction performance and sealing performance through surface strengthening. Repair / regeneration is for valve plates with severe corrosion (e.g., perforation, large-area rust), restoring performance through local repair or complete replacement.

[0003] When damper valve plates undergo surface corrosion treatment to improve surface protection, the valve plates need to be immersed in a film-forming solution to allow the surface corrosion to form a protective film. However, in actual operation, directly placing the valve plates into the film-forming solution container or using a clamp to hold the valve plates into the film-forming solution can easily obstruct the contact area between the valve plates and the container or clamp, affecting the uniformity of the surface treatment. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a damper valve plate corrosion treatment device to more accurately resolve the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a damper valve plate corrosion treatment device, including a base plate, a treatment box fixedly connected to the upper surface of the base plate, and lifting components arranged on both sides of the treatment box on the upper surface of the base plate. The lifting components are provided with multiple placement components, each placement component including a placement plate and a conical column. The placement plate includes two support plates and a fixing ring. The support plates are located on both sides of the fixing ring, and the center of the fixing ring and the center of the conical column are on the same axis. The conical column is located below the fixing ring.

[0007] Preferably, the lifting assembly includes two mounting boxes, which are fixedly connected to the base plate. An electric push rod is installed inside the mounting box, and the telescopic rod of the electric push rod is fixedly connected to a connecting plate. A horizontal plate is fixedly connected to the lower surface of the connecting plate, and the horizontal plate is fixedly connected to all the placement components.

[0008] Preferably, a vertical plate is fixedly connected to one side of all the support plates, the vertical plate is fixedly connected to the horizontal plate, and all the placement components are arranged in an array.

[0009] Preferably, each of the support plates is provided with two through holes, and a sliding rod is slidably connected in each through hole. The lower end of the sliding rod is fixedly connected to a support plate, the conical column is fixedly connected to the support plate, and the upper end of the sliding rod is fixedly connected to a limiting block.

[0010] Preferably, all of the support plates have square through grooves on their upper surfaces, and sliding seats are slidably connected in the square through grooves. An extrusion plate is fixedly connected to one side of the sliding seat, and one side of the extrusion plate is arc-shaped.

[0011] Preferably, a crossbar is fixedly connected to one side of the sliding seat, the crossbar passes through the vertical plate and is slidably connected to the vertical plate, and a spring is fixedly connected between the sliding seat and the vertical plate.

[0012] The damper valve plate corrosion treatment device proposed in this utility model can bring the following beneficial effects:

[0013] Firstly, by setting a fixing ring and a conical column, with the conical column mounted on the support plate, when the valve plate is placed, under the action of gravity, the conical column is lower than the fixing ring. When the valve plate enters the processing box for processing, due to the reduction in the height of the entire placement component, the support plate contacts the bottom surface of the processing box. After the valve plate has been processed for a period of time, the fixing ring and the support plate continue to lower. When the conical column can no longer be lowered, the valve plate is fitted onto the conical column, and the fixing ring and the support plate separate from the valve plate. At this time, the contact position between the valve plate and the conical column has been processed and will not affect the corrosion treatment. The area that was previously blocked is now freed from the blockage due to the separation from the fixing ring and the support plate. At this time, the area on the lower surface of the valve plate is no longer blocked, and the film-forming liquid can perform corrosion treatment on the blocked area of ​​the valve plate, making the corrosion of the valve plate surface more uniform and reducing the blockage. The processing box, placement component and lifting component are all made of corrosion-resistant materials.

[0014] Secondly, by setting up a squeezing block, the crossbars on both sides are pulled to separate the squeezing plates, and the valve plate is placed between the squeezing plates. Then, under the push of the spring, the squeezing plates are squeezed on the outside of the valve plate to squeeze and fix the valve plate, so as to prevent the valve plate from falling off when it is lifted and lowered into the processing box.

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0021] like Figures 1-4 As shown, an embodiment of this utility model proposes a damper valve plate corrosion treatment device, including a base plate 1. A treatment box 2 is fixedly connected to the upper surface of the base plate 1. Lifting components 3 are arranged on both sides of the treatment box 2 on the upper surface of the base plate 1. Multiple placement components 4 are provided on the lifting components 3. Each placement component 4 includes a placement plate 41 and a conical column 42. The placement plate 41 includes two support plates 411 and a fixing ring 412. The support plates 411 are located on both sides of the fixing ring 412. The centers of the fixing ring 412 and the conical column 42 are on the same axis. The conical column 42 is located below the fixing ring 412. In use, the annular valve plate is first placed on the fixing ring 412 and the support plates 411, so that the valve plate is aligned with the fixing ring 412, and the center of the valve plate is controlled to be on the same axis as the center of the conical column 42. Then, the lifting device controls all the placement components 4 to slowly descend into the processing tank 2. At this time, the processing tank 2 contains a film-forming liquid, which can corrode the valve plate to form a corrosion layer to improve its corrosion resistance. When the valve plate comes into contact with the film-forming liquid, the contact position between the valve plate and the fixing ring 412 and the support plate 411 is blocked, and the film-forming liquid corrodes the position. Therefore, after a period of corrosion, the lifting component 3 controls the continued descent, and the conical column 42 is gradually inserted into the circular hole in the center of the valve plate, so that the valve plate separates from the descending fixing ring 412 and the support plate 411. At this time, the area on the lower surface of the valve plate is no longer blocked, and the film-forming liquid can corrode the blocked area of ​​the valve plate, making the corrosion of the valve plate surface more uniform and reducing the blockage. The processing tank 2, the placement components 4 and the lifting component 3 are all made of corrosion-resistant materials.

[0022] like Figure 1 and Figure 2As shown, the lifting assembly 3 includes two mounting boxes 31, which are fixedly connected to the base plate 1. An electric push rod 32 is installed inside the mounting box 31. The telescopic rods of the electric push rod 32 are all fixedly connected to the connecting plate 33. A horizontal plate 34 is fixedly connected to the lower surface of the connecting plate 33. The horizontal plate 34 is fixedly connected to all the placement assemblies 4. A vertical plate 5 is fixedly connected to one side of all the support plates 411. The vertical plate 5 is fixedly connected to the horizontal plate 34. All the placement assemblies 4 are arranged in an array. The support plates 411 and the fixing rings 412 in all the placement assemblies 4 are fixed to the horizontal plate 34 through the vertical plate 5, thereby fixing all the placement assemblies 4 on the horizontal plate 34. The horizontal plate 34 is connected to the electric push rod 32 through the connecting plate 33. In this way, multiple valve plates can be corroded at one time, which speeds up the processing speed.

[0023] like Figure 3 and Figure 4 As shown, each support plate 411 has two through holes, and a sliding rod 6 is slidably connected in each through hole. The lower end of the sliding rod 6 is fixedly connected to a support plate 7, and the conical column 42 is fixedly connected to the support plate 7. The upper end of the sliding rod 6 is fixedly connected to a limiting block 8. The conical column 42 is installed on the support plate 411. When the valve plate is placed, under the action of gravity, the conical column 42 is lower than the fixing ring 412. When the valve plate enters the processing box 2 for processing, the height of the entire placement assembly 4 decreases, and the support plate 7 contacts the bottom surface of the processing box 2. After the valve plate has been processed for a period of time, the fixing ring 412 and the support plate 411 continue to decrease. When the conical column 42 can no longer decrease, the valve plate is fitted onto the conical column 42, and the fixing ring 412 and the support plate 411 are separated from the valve plate. At this time, the contact position between the valve plate and the conical column 42 has been processed and will not affect the corrosion treatment. The area that was previously blocked is now no longer blocked because it is separated from the fixing ring 412 and the support plate 411, making it convenient for corrosion treatment.

[0024] like Figure 3 and Figure 4 As shown, all support plates 411 have square through grooves on their upper surfaces. Sliding seats 9 are slidably connected in the square through grooves. A pressing plate 10 is fixedly connected to one side of the sliding seat 9. One side of the pressing plate 10 is arc-shaped. A crossbar 11 is fixedly connected to one side of the sliding seat 9. The crossbar 11 passes through the vertical plate 5 and is slidably connected to the vertical plate 5. A spring 12 is fixedly connected between the sliding seat 9 and the vertical plate 5. When the valve plate is placed on the fixing ring 412, the crossbars 11 on both sides are pulled to separate the pressing plates 10. The valve plate is placed between the pressing plates 10. Then, under the push of the spring 12, the pressing plates 10 are pressed against the outside of the valve plate to press and fix the valve plate, preventing the valve plate from falling off when it is lifted and lowered into the processing box 2.

[0025] Working principle: First, place the annular valve plate on the fixing ring 412 and the support plate 411. Pull the crossbars 11 on both sides to separate the extrusion plate 10. The valve plate is placed between the extrusion plates 10. Then, under the push of the spring 12, the extrusion plate 10 is pressed against the outside of the valve plate to compress and fix it. The electric push rod 32 pulls the connecting plate 33 to make all the valve plates enter the treatment tank 2 and immerse them in the film-forming solution. After a period of time, the fixing ring 412 and the support plate 411 continue to lower, and the conical column 42 can no longer be lowered. The valve plate is fitted onto the conical column 42, and the fixing ring 412 and the support plate 411 are separated from the valve plate. At this time, the contact position between the valve plate and the conical column 42 has been processed and will not affect the corrosion treatment. The area that was previously blocked is now no longer blocked because it is separated from the fixing ring 412 and the support plate 411, making it convenient for corrosion treatment.
