Automatic chemical supply device

Abstract

The invention aims to provide an arrangement structure of an automatic chemical supply device. When an operator places a hose on a placing part, the placing part is as close as possible to the operator, and diseases of the operator can be prevented from being caused. The arrangement structure of the automatic chemical supply device embodying this object includes a building wall (700) and an open part connecting the inside and outside of a building in a communication mode. The automatic chemical supply device comprises the placing part (150) and a conveying unit (160), wherein a chemical hose (500) for supplying chemicals from a chemical tank is placed on the placing part (150), and the conveying unit (160) conveys the placing part (150) back and forth, so that the chemical hose (500) is connected with the chemical tank in the building. When a worker places the chemical hose (500) on the placing part (150), the placing part (150) is located within the interior space of the open part 701.

Description

[0001] This application is a divisional application of the invention patent application "installation structure of automatic chemical supply device" with the application date of August 24, 2017 and the application number of 201710735184.X. technical field [0002] The invention relates to an automatic chemical supply device. In more detail, the hose shelving part is arranged on the opening part of the wall, which improves the working convenience and prevents the operator from being injured. Background technique [0003] Generally, companies that manufacture semiconductors, semiconductor devices, LCDs, OLEDs, pharmaceutical companies, and paint companies that use hazardous chemicals use a variety of chemicals, and the methods of safely supplying these chemicals are also diversifying. [0004] This chemical is generally transported from the chemical tank of the tank truck (tank lorry) parked outside the building to the chemical storage tank (chemical storage tank) in the buildi...

Problems solved by technology

[0016] But according to this structure, to put the heavy chemical hoses and nitrogen hoses to the shelving part in the building, the staff must bend down to put the hoses to the shelving part, but this work will be difficult due to the weight of the hoses. Causes of musculoskeletal disorders in workers

[0017] Moreover, when transporting chemicals and nitrogen, chemical hoses and nitrogen hoses are connected to tank trucks and chemical storage tanks and nitrogen storage tanks, and there is a problem that chemical leak-proof screen doors cannot be installed

Moreover, even if a screen door is installed, the surrounding space where the hose is connected to the joint cannot be closed, leaving it exposed

Therefore, there is a problem that external pollutants such as dust, rainwater, and snow will flow into the device, and chemical fumes (Fume) generated in the device will also directly leak out.
