Description

Technical Field

[0001] This utility model relates to the field of metal material processing and surface treatment, and in particular to a galvanized pipe washing device. Background Technology

[0002] Galvanized pipe, a type of metal pipe coated with a zinc layer, is widely used in building water supply and drainage, agricultural irrigation, and industrial transportation due to its excellent corrosion resistance and mechanical properties. Water washing is a key process in galvanized pipe production. Its main function is to remove residual zinc slag, acid, and other impurities from the pipe surface after galvanizing, providing a clean surface for subsequent processing and directly affecting the final quality and service life of the galvanized pipe.

[0003] Existing galvanized pipe washing equipment typically consists of a frame, spray units, and a conveying mechanism. Its working principle is as follows: the conveying mechanism feeds the galvanized pipe into the washing area; the spray units, connected to an external water source, spray clean water onto the pipe surface through nozzles; the impact force of the water flow washes away surface impurities, and the wastewater is discharged through a bottom collection structure. Some systems may be equipped with multiple spray units to enhance the cleaning effect.

[0004] In existing technologies, galvanized pipes are mostly transported in a straight line by conveyor rollers during the water washing process. The pipe body remains horizontal and stationary, which makes it difficult for the bottom of the pipe to be directly washed by the water flow, forming a cleaning dead zone. Residual impurities can easily cause coating defects in subsequent processes. Therefore, a galvanized pipe water washing device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a galvanized pipe washing device, which aims to improve the problem of incomplete cleaning caused by the static state of the pipe in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A galvanized pipe washing device includes a protective cover and a support plate. The protective cover is equipped with a spraying mechanism inside, and the support plate is equipped with an automatic flipping mechanism inside. The upper end of the support plate is equipped with a slag scraping mechanism. The automatic flipping mechanism includes a first fixing plate, which is externally fixedly connected to the adjacent side of two support plates. A first serrated plate is fixedly connected to the upper end of the first fixing plate. A second fixing plate is slidably connected to the adjacent side of the two first fixing plates. A second serrated plate is fixedly connected to the upper end of the second fixing plate. A first connecting plate is fixedly connected to the front end of the second fixing plate. A first fixing shaft is fixedly connected inside the first connecting plate, and a cylinder is fixedly connected to the outside of the first fixing shaft.

[0008] As a further description of the above technical solution:

[0009] The slag scraping mechanism includes a fixed block, the lower end of which is fixedly connected to the upper end of the support plate, and a spring is fixedly connected inside the fixed block. A cleaning component is provided at the lower end of the spring.

[0010] As a further description of the above technical solution:

[0011] The cleaning assembly includes a fixing plate three, the upper end of which is fixedly connected to the lower end of the spring, and a connecting plate two is fixedly connected to the lower end of the fixing plate three. The internal thread of the connecting plate two is connected to a bolt, and the external thread of the bolt is connected to a scraper.

[0012] As a further description of the above technical solution:

[0013] The spraying mechanism includes a water inlet pipe, the outside of which is fixedly connected to the inside of the protective cover. A horizontal spray pipe is fixedly connected to the left side of the water inlet pipe, a vertical spray pipe is fixedly connected to the front end of the horizontal spray pipe, and a spray head is fixedly connected to the lower end of the vertical spray pipe.

[0014] As a further description of the above technical solution:

[0015] The support plate is fixedly connected to a second fixed shaft, the front end of the second fixed shaft is fixedly connected to a water tank, and the water tank is fixedly connected to a drain pipe.

[0018] As a further description of the above technical solution:

[0019] The outer side of the connecting plate 2 is slidably connected to the inside of the scraper, and the scraper has an arc shape.

[0021] The upper end of the horizontal spray pipe is fixedly connected to the lower end of the protective cover, and the upper end of the vertical spray pipe is fixedly connected to the lower end of the protective cover.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a cylinder drives a second fixed plate to slide along a first fixed plate, causing a second serrated plate to work in conjunction with a first serrated plate to create an alternating lifting and lowering motion, which drives the galvanized pipe to automatically flip during the water washing process. This structure changes the contact angle between the pipe body and the spray water flow, ensuring that the surface of the pipe body and hidden parts can be thoroughly rinsed, effectively solving the problem of dead corners in traditional water washing.

[0024] 2. In this utility model, under the action of the spring, the scraper of the scraping mechanism always adheres to the surface of the support plate. Combined with the detachable design of the bolted connection, this enables real-time cleaning of residue and convenient component replacement. The cleaning component, through the sliding cooperation between the arc-shaped scraper and the second connecting plate, improves the thoroughness of residue removal and avoids the impact of impurities adhering to subsequent processing.

A spring 52 is fixedly connected inside the fixed block 51. A cleaning component 53 is provided at the lower end of the spring 52. The cleaning component 53 scrapes and cleans galvanized pipes of different diameters through the spring 52. The cleaning component 53 includes a fixed plate 3 531, the upper end of which is fixedly connected to the lower end of the spring 52. The fixed plate 3 531 can compress the spring 52 when it rises.

[0034] Reference Figures 1 to 3The spraying mechanism 3 includes a water inlet pipe 31, which is externally and fixedly connected to the inside of the protective cover 1. A horizontal spray pipe 32 is fixedly connected to the left side of the water inlet pipe 31, through which water flows into the horizontal spray pipe 32. A vertical spray pipe 33 is fixedly connected to the front end of the horizontal spray pipe 32, through which water flows into the vertical spray pipe 33.

Protective cover 1 prevents water from splashing out.

[0035] Working principle: When the automatic flipping mechanism 4 is working, the cylinder 47 is driven by the fixed shaft 46 and the connecting plate 45, which drives the fixed plate 43 to slide on the fixed plate 41. When the fixed plate 43 moves, the serrated plate 44 at its upper end and the serrated plate 42 on the fixed plate 41 form an alternating lifting motion. The height difference of the serrated structure pushes the galvanized pipe placed on the support plate 2. With the extension and retraction cycle of the cylinder 47, the serrated plate 44 alternately completes the rising and falling action, so that the galvanized pipe can continuously flip around its own axis during the water washing process. This flipping process ensures that all surfaces of the galvanized pipe can be evenly contacted by the water flow sprayed by the spraying mechanism 3, completely eliminating the cleaning blind spots under the traditional fixed conveying method.

[0036] When the slag scraping mechanism 5 is working, the spring 52 inside the fixed block 51 always applies downward elastic pressure to the cleaning component 53. When the galvanized pipe is conveyed or flipped on the support plate 2, the zinc slag and impurities that fall off the surface will be pushed to the scraper 534 in real time. The cleaning component 53 slides with the scraper 534 through the connecting plate 2 532. With the curved surface design of the arc-shaped scraper 534, it can efficiently gather and scrape off the residue on the support plate 2. The bolt 533 connection structure allows the scraper 534 to be quickly disassembled and replaced according to the wear condition, ensuring the long-term stability of the slag scraping effect and avoiding secondary pollution caused by residue accumulation.
