Dust removal system for polystyrene foam plate forming machine and application of dust removal system

Abstract

The invention relates to a dust removal system for a polystyrene foam plate forming machine and application of the dust removal system. The dust removal system comprises an absorption device, a primary filter device, a secondary filter device and a discharge device. The absorption device, the primary filter device, the secondary filter device and the discharge device are sequentially connected with one another, a water tank is arranged at the bottoms of the primary filter device and the secondary filter device, and a water pump is arranged in the water tank and is connected with spraying devices in the primary filter device and the secondary filter device by water inlet pipes. The dust removal system for the polystyrene foam plate forming machine and the application have the advantages that granular dust (mainly escaping polystyrene pre-expansion granules) can be effectively filtered and removed in operation procedures of the forming machine, accordingly, operation environments can be improved for workers, and atmospheric pollution due to the traditional straightforward methods for directly discharging granule dust into the atmosphere can be prevented; the dust removal system has an excellent economic benefit and excellent market value; the dust removal system is scientific and reasonable in structural design and worthy of popularization and application, obvious dust removal effects can be realized by the dust removal system, and environmental protection requirements can be met.

Description

technical field [0001] The invention relates to a dust removal system for a polystyrene foam board forming machine and its application, belonging to the technical field of wall insulation material process equipment. Background technique [0002] In recent years, with the rapid development of the real estate industry, in accordance with national construction standards, it is necessary to construct wall insulation materials on the outer walls of the house to achieve a large saving of wall materials, improve wall insulation performance, save resources, and reduce environmental pollution requirements. [0003] Existing wall insulation materials include benzene board, polystyrene board, extruded board, polystyrene foam board, rigid polyurethane foam, polycarbonate and the like. Among them, polystyrene foam board is more and more widely used. Polystyrene foam board, also known as foam board and EPS board, is a kind of wall insulation material widely used at present, which is main...

AI Technical Summary

Problems solved by technology

[0004] At present, in the workshop for processing polystyrene foam boards, due to the relatively light weight of the foamed particles, the foamed particles need to be transported through long-distance pipelines before entering the molding machine, and most of the existing feeding ports of the molding machines are open. When the foam particles are input into the molding machine, a large amount of raw material dust will often escape from the workshop. The current polystyrene foam board production workshop often has a strong pungent smell and poor air quality. Workers often need to wear Protective clothing, gloves, wearing thick masks and hats, but working in this kind of working environment for a long time will affect the health of workers, and the working environment of the workshop does not meet the national standards

[0005] Aiming at such a poor working environment, a relatively simple and common method is often adopted. Ventilation windows and exhaust fans are set up in the workshop to directly discharge the strong smell and raw material dust from the workshop into the external atmosphere. To a certain extent, the working environment in the workshop has been improved. However, the manufacture of polystyrene foam boards belongs to the chemical industry. Most of the materials and a large number of reactions in the manufacturing process are polluted. The practice of directly discharging them into the atmosphere will cause pollution to the atmospheric environment.

[0006] Therefore, it is necessary to design a dust removal and purification device to solve the problem of poor environment and serious pollution in the workshop
