Efficient and environmentally friendly coating pre-treatment shed equipment

Abstract

The invention discloses efficient and environmental-friendly coating pre-treatment shed body equipment which comprises a shed body. The shed body is formed by splicing a shed body top plate, shed bodyside plates and a flow guide bottom plate together. The shed body comprises spray buffer zones located at the front and back ends and a spray area located between the two spray buffer zones. A refluxinlet is arranged in the bottom of one of the two spray buffer zones, the reflux inlet of a long and narrow port structure divides the flow guide bottom plate located at the bottom into two parts, aninserting coaming inserted into a liquid slot is arranged at the lower end of the reflux inlet, and the inserting coaming protrudes toward the bottom of the shed body. The efficient and environmental-friendly coating pre-treatment shed body equipment not only can meet pre-treatment demands, but also can solve problems of an existing shed body. By considering factors of energy conservation, environmental protection, work efficiency and the like, compared with a commonly used shed body in industry, the efficient and environmental-friendly coating pre-treatment shed body equipment is convenientto maintain and energy-saving and emission-reducing, protects a workshop environment, and establishes a clean production environment favorably.

Description

technical field [0001] The invention relates to a high-efficiency and environment-friendly coating pre-treatment shed equipment, which belongs to the field of clean production in the coating process. Background technique [0002] Coating is a technology for covering the surface of the product. Coating not only makes the product look bright, but more importantly, it improves the product's anti-corrosion and anti-oxidation capabilities, thereby greatly extending the service life of the product. After metal products are processed, transported, stored and other production links, the surface inevitably has impurities such as oxide film, rust, welding slag, grease, etc. In order to ensure that the coating layer is firmly attached to the surface of the workpiece, pre-treatment must be carried out before coating Otherwise, it will not only affect the bonding force between the coating and the base metal, but also reduce the quality of the coating, and when the base metal is protected...

AI Technical Summary

Problems solved by technology

[0005] (a) The layout design and type selection design of the nozzles are unreasonable: ①The pump power is high, resulting in increased energy consumption; ②The spray pressure and flow are not uniform, and the cleaning effect of the workpiece is poor; ③The liquid splashes out of the shed, resulting in waste of resources and environmental damage. Pollution;

[0006] (b) The liquid backflow speed is slow: there is a filter screen on the backflow port to prevent small workpieces including the silicone protective sleeve on the parts from falling into the liquid pump and easily causing shutdown failure

However, with use, the dirt on the surface of the workpiece accumulates on the filter screen, so that the liquid cannot quickly return to the liquid tank, and the liquid tank will be replenished due to lack of liquid. On the one hand, the liquid medicine is diluted, and on the other hand, when the machine is shut down, all the liquid flows back , often exceeds the volume of the liquid tank, causing the liquid to overflow, resulting in waste of resources and environmental pollution;

[0007] (c) The return port is generally designed in the middle of the lower shed body. Above this position is a circular spray pipe, which makes it difficult to clean the return port and pick up dropped parts and protective covers;

[0008] (d) There are side plates on both sides of multiple groups of "ring pipes" to block the sprayed dispersed liquid flow. Due to design defects, the blocking effect is poor, and it is easy to cause liquids in different spraying sections to channel, resulting in liquid pollution , must be replaced in advance, resulting in waste of resources and environmental pollution;

[0009] (e) The connection of different spraying sections is the highest point, because there is no partition plate designed, resulting in liquid leakage in different spraying sections, resulting in waste of resources and environmental pollution;

[0010] (f) The shed body and the liquid tank are all bent and spliced ​​by pieces of metal. In order not to leak, they need to be fully welded around. The general shed body is about 100 meters long. The larger the workpiece to be processed, the larger the shed body required. The larger the volume, the larger the welding workload, which wastes resources and is not conducive to disassembly and reassembly
