Automatic chemical supply device

Abstract

The invention aims at providing an automatic chemical supply device. When an operator puts a hose to a placement part, the placement part is made as close to the operator as possible to prevent triggering any disease of the patient. To achieve the purpose, the automatic chemical supply device structurally comprises a building wall body (700) and an automatic chemical supply device, wherein the building wall body (700) penetrates through an opening part inside and outside a building, the automatic chemical supply device comprises the placement part (150) and a conveying unit (160), the placement part (150) is used for placing a chemical hose (500) from a chemical tank for chemical purposes, the conveying unit (160) conveys the placement part (150) front and back, and in this way, the chemical hose (500) is connected with the chemical tank in the building. When a worker puts the chemical hose (500) at the above placement part (150), the placement part (150) is located in the internal space of the opening part (701).

Description

[0001] This application is a divisional application with an application date of August 24, 2017 and an application number of 201710735184.X invention patent application "Installation structure of automatic chemical supply device". Technical field [0002] The invention relates to an automatic chemical supply device. In more detail, a hose holding part is arranged in an open part of a wall to improve work convenience and prevent operator injuries. Background technique [0003] In general, companies that manufacture semiconductors, semiconductor devices, LCDs, and OLEDs, pharmaceutical companies, paint companies, and other companies that use hazardous chemicals use a variety of chemicals, and the ways to safely supply these chemicals are also diversified. [0004] This chemical is generally transported from the chemical tank of the tank lorry parked outside the building to the chemical storage tank inside the building, and then transported from the chemical storage tank to the unit pro...

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.
