Description

Technical Field

[0001] This utility model relates to the field of phosphating protection technology for metal materials, and in particular to a scraper mechanism for a phosphating tank. Background Technology

[0002] Phosphating is a process involving chemical and electrochemical reactions to form a phosphate conversion film, known as a phosphate coating, which is used to protect metallic materials. Commonly used phosphating equipment includes phosphating tanks where metal materials or workpieces are immersed in a phosphating solution. During operation, phosphate slag forms on the tank walls, requiring periodic drainage and replacement of the phosphate solution for cleaning and maintenance. Existing technologies also include methods to scrape and clean the phosphate slag from the tank walls during operation, allowing it to settle and be discharged. However, see [link to relevant documentation]. Figure 2 and Figure 3 The existing scraper uses an acute-angled scraping surface to remove phosphating slag from the tank wall, but the scraped phosphating slag will detach from the scraper and drift into the phosphating solution in large quantities, resulting in poor slag removal and affecting the phosphating effect of the ongoing phosphating work.

[0003] Therefore, those skilled in the art are dedicated to developing a phosphate tank scraper mechanism that has good slag removal effect and does not affect the phosphate treatment effect. Summary of the Invention

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is to provide a phosphating tank scraper mechanism with good slag removal effect and without affecting the phosphating effect.

[0005] To achieve the above objectives, this utility model provides a scraper mechanism for a phosphating tank, suitable for horizontal reciprocating motion against the tank wall to scrape the tank wall. It includes a scraper body, with the direction of movement of the scraper body as a first direction, the vertical direction of the tank wall as a second direction, and a direction perpendicular to the tank wall as a third direction, wherein the first direction, second direction, and third direction are orthogonal to each other. The scraper body has a first scraping surface and a second scraping surface symmetrically arranged in the first direction.

[0006] The cross-sectional shape of the scraper body in the orthogonal plane formed by the first direction and the second direction is a first isosceles trapezoid that is wider at the top and narrower at the bottom. The first scraping surface and the second scraping surface respectively constitute the two sides of the first isosceles trapezoid.

[0007] The cross-sectional shape of the scraper body in the orthogonal plane formed by the first direction and the third direction is a second isosceles trapezoid, and the first scraping surface and the second scraping surface respectively form the two legs of the second isosceles trapezoid; the contact surface between the scraper body and the groove wall forms the short base of the second isosceles trapezoid.

[0008] Both the first and second scraping surfaces have scraping sections formed on the side closest to the tank wall, while the side away from the tank wall forms a material blocking section.

[0009] Furthermore, the scraper body and the surface opposite to the contact surface are respectively provided with a transmission connector connected to the drive mechanism and a guide connector connected to the guide rod.

[0010] Furthermore, the drive mechanism is a cylinder or a lead screw mechanism.

[0011] Furthermore, both the first and second scraping surfaces are groove-shaped, and the material blocking part and the scraping part respectively constitute the two high points of the groove.

[0012] Furthermore, the groove is a V-shaped groove, an arc-shaped groove, or a circular groove with a circumferential angle greater than 180 degrees.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The scraper body is designed as a first isosceles trapezoid, wider at the top and narrower at the bottom. During horizontal scraping, this allows the phosphate slag scraped off the tank wall to flow downwards along the scraping surface, significantly reducing the amount of phosphate slag drifting into the phosphate solution and facilitating its rapid settling. The scraper body's cross-section is designed as a second isosceles trapezoid, creating a baffle on the scraping surface, increasing the difficulty for the phosphate slag to flip over the scraper body and detach. Through this design, a semi-enclosed channel is created on the scraping surface to guide the phosphate slag towards the bottom of the tank, improving scraping efficiency and preventing the phosphate slag from drifting and affecting the phosphate treatment effect.

[0025] The following description, with reference to the accompanying drawings, illustrates several preferred embodiments of the present invention to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0026] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and this invention does not limit the dimensions and thicknesses of each component. To make the illustrations clearer, the thickness of some components has been appropriately exaggerated in the drawings.

[0027] like Figure 1 , 4 As shown, the scraper mechanism of the phosphating tank of this utility model is suitable for horizontal reciprocating motion against the tank wall to scrape the tank wall. It includes a scraper body 11, with the movement direction of the scraper body 11 as the first direction, the vertical direction of the tank wall as the second direction, and the direction perpendicular to the tank wall as the third direction. The first direction, the second direction, and the third direction are orthogonal to each other. The scraper body 11 is symmetrically provided with a first scraping surface 12 and a second scraping surface 13 in the first direction.

[0028] like Figure 4 As shown, the cross-sectional shape of the scraper body 11 in the orthogonal plane formed by the first direction and the second direction is a first isosceles trapezoid that is wider at the top and narrower at the bottom. The first scraping surface 12 and the second scraping surface 13 respectively constitute the two sides of the first isosceles trapezoid.

[0029] like Figure 4-5 As shown, the cross-sectional shape of the scraper body 11 in the orthogonal plane formed by the first direction and the third direction is a second isosceles trapezoid, and the first scraping surface 12 and the second scraping surface 13 respectively form the two legs of the second isosceles trapezoid; the contact surface between the scraper body 11 and the groove wall forms the short base of the second isosceles trapezoid.

[0030] like Figure 6-8As shown, the first scraping surface 12 and the second scraping surface 13 are both formed with scraping parts 15 on the side close to the tank wall, and the side away from the tank wall is formed with a material blocking part 14.

[0031] The working principle of the scraper mechanism is explained below. When the scraper body 11 reciprocates in the horizontal direction, the first scraping surface 12 and the second scraping surface 13 perform scraping work on the outward and return strokes, respectively. The first isosceles trapezoid, which is wider at the top and narrower at the bottom, causes the first scraping surface 12 and the second scraping surface 13 to be inclined inward from top to bottom. During horizontal scraping, this inclination allows the phosphate slag that has been scraped off the tank wall to flow downward along the first scraping surface 12 or the second scraping surface 13, greatly reducing the amount of phosphate slag that drifts into the phosphate solution and facilitating the rapid settling of the phosphate slag. The shape of the second isosceles trapezoid creates a baffle on the first scraping surface 12 and the second scraping surface 13, increasing the difficulty for the phosphate slag to flip over the scraper body 11 and detach from the drift. In summary, by setting up the first and second isosceles trapezoids, a semi-enclosed channel is formed on the scraping surface to guide the phosphating slag to the bottom of the tank, which improves the scraping efficiency and prevents the phosphating slag from drifting and affecting the phosphating effect.

[0032] Furthermore, the scraper body 11 is provided with a transmission connector 2 connected to the driving mechanism and a guide connector 3 connected to the guide rod on the surface opposite to the contact surface.

[0033] Furthermore, the drive mechanism is a cylinder or a lead screw mechanism.

[0034] Furthermore, both the first scraping surface 12 and the second scraping surface 13 are groove-shaped, and the material blocking part 14 and the scraping part 15 respectively constitute the two high points of the groove.

[0035] Furthermore, such as Figure 6-8 As shown, the groove is a V-shaped groove, an arc-shaped groove, or a circular groove with a circumferential angle greater than 180 degrees.

[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
