Description

This Utility Model Patent deals with an unprecedented and innovative product, which offers excellent accessibility, security and economy.

APPLICATION FIELD

Used in laboratory environments.

TECHNICAL STATUS

The concept of chemical chapel with exhaustion has always been treated, especially in Brazil, as one of the items of laboratory furniture. Following old criteria inherited in carpentry workshops and widely accepted by the market, in general, without considering possible conceptual errors in the design / construction / safety / ventilation or due to simple lack of knowledge, they place many operators at risk of exposure to harmful agents.

This scenario is not tolerated in most countries in Europe and the USA with rules of manufacture and objective tests.

The traditional Chapel (Local Exhausting Cabin) is a piece of furniture built and structured in wood, consisting of a lower cabinet, a Box with a flat work surface with a drain and valves surrounded by a suitable covering with an outlet to capture the air conducted by ducts to the outside through the centrifugal motor, electrical panel and closed top panel.

Being completely built in wooden sheets, internally the work area the BOX (straight corners, worktop with tub + valves) little space, safety air flow system, absence of upper bypass grill and lower apparatus

Airfoil and flow monitor. Lower unit without ventilation, used to store chemical containers.

DESCRIPTION OF THE INVENTION

After several studies and researches, the CONSTRUCTIVE ARRANGEMENT APPLIED IN CHEMICAL CHAPEL WITH EXHAUSTION MODEL ECO-DC, now in question and object of the present patent, was able to offer excellent accessibility, since removing the lower module inclusion of people with physical disabilities at work, improves work safety in the laboratories (structure, capsule type box, space and functionality). And generating a substantial saving of energy spent on the time of use of the equipment and the concern of production, finishes, handling of leftovers and the final destination of the product's useful life considering minimizing the environmental impact.

This CONSTRUCTIVE PROVISION APPLIED IN CHEMICAL CHAPEL WITH EXHAUSTION brings a series of advantages and benefits, among which we highlight:

- Technical Advantages: Greater safety for laboratory personnel, iron structure with special painting, Box type capsule with easily removable top, lower module with casters and ventilation.

- Operational Advantages: Ease of controls placed on the panels, greater space in the internal area for work (without the space of the bowl and the remote control valves), ease of maintenance and weight reduction.

- Accessibility: Removing the lower module, it allows the inclusion of people with physical disabilities at work.

3/6

- Environmental Advantages: Savings in relation to the consumption of energy throughout its useful life and the concern with production, finishes, handling of leftovers and the final disposal destination of the product, was taken into consideration to minimize to the maximum in relation to the environmental impact .

According to these illustrations and in the details presented above, the CONSTRUCTIVE ARRANGEMENT APPLIED IN A CHEMICAL CHAPEL WITH EXHAUSTION consists of:

- Valve control (1) with remote control, for fluids and gases, with special connections, installed on the front panel. For maintenance the panel must be removed;

- Base cabinet (2) with exhaust connected to the upper cabinet extraction system, opening doors, polypropylene tray for retaining liquids and casters. When requested, the lower module can be explosion proof;

- Valve (3) in American siphoned polypropylene of 0 3 1/2;

- 110/220 volts 25 ampere socket set (4), mounted on the front panel and on / off button for exhaust motor, protected with PVC box.

- Handle type handle (5) and fixing screws in AISI-304 stainless steel;

- Plastic box (6) containing the protection circuits of the electrical system (magnetic switches, thermal relays and fuses);

- Upper front panel (7) built in galvanized sheet with epoxy paint with VAV-type bypass air passage, with the function of equalizing the internal pressure of the Box and eliminating mini-turbulences, the removable panel also serves to access the luminaire , dumper and electrical controls;

- Nylon pulley systems (8) with counterweights supported with insulated steel cable (coated with PVC) so as not to oxidize;

-8mm tempered crystal glass (9) or in colorless polycarbonate sheet. To remove it will be necessary to disassemble the Airfoil and slide the glass downwards;

- Worktop (10) independent of the Box, built with material with high chemical resistance. It has the facility to be removed for maintenance;

- The Box type capsule with leveling shoes supporting the top, drain and deflator baffles (11) are supplied in GRP, polypropylene or stainless steel and for maintenance the chapel must be disassembled;

- Support structure for the chapel (12) built in iron frames with special painting with levelers, fully removable parts;

- The AirFoil (13) aerodynamic apparatus, lower front that serves to equalize the internal pressure of the Box and integrates the Ventilation System of the Chapel;

- Exhaust system component: Centrifugal engine (14) type sirocco built in PRFV. The standard PVC ducts and curves can also be supplied in polypropylene and stainless steel;

-Chicanas (15) supplied in fiber (FRP), polypropylene sheet or angled upper stainless steel and straight bottom, auxiliary function to direct the air flow;
