Definitions
- the invention relates to a grinding cabin arrangement for installation in buildings with the features specified in the preamble of claim 1.
- Such grinding cabin arrangements are used, for example, in automobile factories when grinding aluminum body parts used.
- aspects also play such as explosion protection, especially with aluminum dusts.
- a ventilation device for air conditioning and generating a against dust-protecting air flow in the cabin and on the other hand one Dust extraction device for guiding away the resulting during processing Provide dusts from the cabin.
- the ventilation device especially if several are arranged Grinding booths in a factory building - a common supply air unit with a main fan provided by an intake through the roof the grinding booths are supplied with outside air via supply air ducts.
- supply air ducts In each of Supply air ducts are again intermediate fans and silencers intended.
- the heating device for the necessary treatment of the outside air to be provided in the intake manifold, for example via the factory existing hot water must be operated.
- the supply air unit is also included equipped with a cooling register to ensure that even at high outside temperatures ensure the required workplace temperature in the grinding cabin.
- the required heating or cooling capacity is regulated by the the corresponding heat exchange register of the heating or cooling Amount of heating or cooling medium set.
- the supply air temperature in the supply air duct in front of the grinding booths with a temperature sensor detected and the corresponding signal processed in a PID controller. With its help, a 3-way valve in the heating or a 2-way valve in the cooling circuit can be opened more or less.
- the invention has for its object to a grinding cabin arrangement improve that the complex supply and treatment of the air supply can be omitted for the ventilation device of the grinding cabin.
- Every grinding cabin is only connected to one suction line from an air-conditioning point of view depends on structural changes in the building much easier and smoother to implement.
- everyone can individual grinding booth through appropriate design of the ventilation modules can be individually adapted to specific ventilation requirements.
- the flexibility can be increased considerably by the ventilation modules of a grinding cabin individually or in groups are controllable. For example, with grinding booths If there is a lot of dust, the ventilation modules are placed closer to the grid ceiling and / or operated with higher performance.
- the ventilation modules can preferably be used in a grinding cabin a common upstream cooling arrangement provided in the respective grinding booth can ensure temperatures conforming to standards, if the temperatures in the factory building itself should be too high.
- decentralized cooling arrangements are far fewer complex to build and operate, like the larger ones discussed at the beginning Plants for central supply air conditioning.
- a factory hall 1 is indicated very schematically, in who installs a grinding booth assembly designated as a whole by 2 is. Several of these arrangements 2 can be in a common factory 1 installed.
- Each such arrangement 2 has a walk-in grinding booth as the centerpiece 3 with side walls 4, a coverable entrance 5 in the form of a Slat curtain 6 and a grid-like ceiling 7.
- Each cabin 3 is supplied with supply air by a ventilation device B.
- ventilation modules 8 are used, which supply air 9 directly relate from the interior of factory hall 1, as is done by the others Arrow 10 is indicated.
- the individual ventilation modules 8 are commercially available, ready-to-connect units with a fan, filter and muffler, such as those from the company Meissner + Wurst GmbH & Co. under the name Filter Fan Units "are offered for clean room technology. They essentially have a box-shaped housing made of aluminum, in which an electrically operated radial fan works. This can be regulated and monitored by speed, which is why corresponding system cables lead from a central control to the respective ventilation module. As the name already suggests indicates that filters for the supply air and silencers are also integrated in the ventilation modules 8, so that there is no acoustic nuisance even when covering the entire surface with modules.
- the ventilation modules generate 8 an air flow in the grinding cabin 3, which is laminar from above runs down. This removes grinding dust from the head area the grinder 12 kept away, which is an inhalation of dusts effectively prevented.
- the ventilation modules 8 with a common cooling arrangement arranged in front of it 14 provided that a fan 15 and a correspondingly designed Heat exchanger 16 exists.
- the dust extraction device designated as a whole is to the Grinding cabin 3 via a detection device 17 with a rotating flow connected.
- the suction device A must - for example for use when grinding aluminum body parts - for a high explosion potential.
- Aluminum particles in air are extremely reactive and can be activated due to the lowest activation potential lead to dust explosions.
- all tubes 18 are for Exhaust air duct designed as seamlessly flanged stainless steel pipes. That from the detection device 17 outgoing pipe 18.1 leads over a Explosion quick-closing slide 19 to a dry filter 20, which acts as a container in a pressure-resistant design for an expected explosion pressure of 10 bar.
- the raw gas side before the dry filter 20 arranged quick-action slide valve 19 closes the exhaust air line suddenly rising pressure within a few milliseconds.
- the dry filter 20 On the clean gas side, the dry filter 20 has an explosion protection valve 21 subordinate, that automatically with increasing pressure - without external drive like the slide 19 - closes.
- the dry filter 20 is in the remaining connected to the collecting container 22 for the aluminum dust.
- the connecting line 18.2 there is a double slide system that is pressure-shock resistant to 10 bar 23.
- the cleaned exhaust air is led to the outside via the exhaust air line 18.3. the latter in the direction of flow 24 of the exhaust air after the explosion protection valve 21 a motor-controlled closure flap 25, a fan 26, a silencer 27 and a bushing 28 in the building ceiling 13 has.
- a motor-controlled closure flap 25 In the bushing 28 is a water trap integrated against ingress of rainwater.
- Two ejectors 36, 37 are connected via corresponding branch lines 35 supplied with compressed air, at the suction connection of the two suction lines 30 or 32 are connected. The one for the supply of the tool extraction
- the branch line 35 provided is by its own shut-off valve 38 lockable.
- the two branch lines 35 open before Rapid shot slide 19 in the exhaust air line 24 of the suction device A.
- the dry filter 20 has another Line 18.4 is connected to the exhaust line 18.3 and before the bushing 28 flows into. There is a solenoid valve 39 in line 18.4 arranged, which is opened when the system is at a standstill and for the removal of Hydrogen from the dry filter 20 leads.
- Hydrogen is produced from the reaction of aluminum dust with that due to the natural humidity in the dry filter 20 existing water vapor.
