Abstract
Description
Technical Field
[0001] This utility model relates to the field of zinc plate surface treatment, and in particular to a degreasing spray device for zinc plates. Background Technology
[0002] Degreasing the surface of zinc plates is a key step, mainly aimed at removing impurities such as rolling oil, lubricant, dust, and oxides from the zinc plate surface to ensure the adhesion and surface quality of the subsequent galvanized layer.
[0003] Conventional zinc plate processing often employs immersion degreasing machines or spray degreasing machines. Immersion degreasing machines submerge the zinc plate in a degreasing agent, but during this process, impurities in the degreasing agent will re-adhere to the next zinc plate that needs degreasing, making it unsuitable for degreasing large quantities of zinc plates. Spray degreasing machines degrease the upper and lower surfaces of the zinc plate by spraying degreasing agent, but they often do not spray the sides (thickness direction) of the zinc plate during the degreasing process, thus failing to achieve side degreasing.
[0004] In summary, how to achieve spray degreasing of the sides of zinc plates has become an urgent problem for researchers in this field. Summary of the Invention

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0019] See Figure 1 , 2 This embodiment is a degreasing spraying device for zinc plates, including: a frame 1, a cleaning tank 2 with an upward opening at the top of the frame; two rotary conveyor chains 3 are arranged on the left and right sides inside the cleaning tank 2, and multiple support rods 4 are arranged at intervals and parallel to the width direction of the cleaning tank 2. The two ends of the support rods 4 are respectively connected to the links on different rotary conveyor chains 3; when the zinc plate is placed on the support rods 4, the rotary conveyor chains 3 rotate, driving the zinc plate to move and transport horizontally on the cleaning tank 2.
[0020] See Figure 3The spray assembly 5 consists of an upper spray pipe 51, a lower spray pipe 52, and a first side pipe 53 forming a C-shaped structure, totaling three sets. This increases the spraying range and efficiency of the zinc plate. The nozzles 55 on the upper spray pipe 51 spray the upper surface of the zinc plate for degreasing, the nozzles 55 on the lower spray pipe 52 spray the lower surface of the zinc plate for degreasing, and the nozzles 55 on the first side pipe 53 spray the left side of the zinc plate for degreasing. A second side pipe 54 is provided with one end of the lower spray pipe 52 facing downwards, and the nozzles 55 on the second side pipe 54 spray the right side of the zinc plate for degreasing. In summary, this achieves spray degreasing of the upper surface, lower surface, and left and right sides of the zinc plate.

A drain pipe 59 is provided at the bottom of the liquid storage tank 57.
[0023] In this embodiment, a liquid storage tank 57 is provided below the cleaning tank 2. The liquid storage tank 57 stores degreasing agent. The degreasing agent is pumped into the first side pipe 53 through the pump body 58. The degreasing agent is then moved to the other pipes through the first side pipe 53 to participate in degreasing. One end of the liquid inlet pipe 56 is connected to three parallel first side pipes 53 through a four-way connector.
[0024] In some possible embodiments, see Figure 2 , 4 A filter frame 61 is installed inside the liquid storage tank 57, and a filter screen 62 is installed inside the filter frame 61. One end of the return pipe 63 is located above the filter frame 61 inside the liquid storage tank 57, and the other end of the return pipe 63 is connected to the bottom of the cleaning tank 2.
