Definitions
- the invention relates to a spray booth according to the preamble of claim 1 and a circulation system according to the preamble of claim 7.
- the size of the spray booths is adapted to the average size of the objects to be processed in such a way that a work area remains around the objects placed in the central area of the interior, which enables the working personnel to spray the object from all sides.
- Spray booths for passenger cars have a base area with a length of at least 7 m and a width of at least 4 m.
- a vehicle to be machined is placed in the center of the interior in the direction of the longitudinal axis of the cabin through a short side wall designed as an entrance gate.
- the car stands on a grate under which an exhaust air filter is held is.
- An exhaust air duct is formed under the exhaust air filter, through which the exhaust air flowing through the filter layer can flow to an air drive device.
- the known spray booths require an approximately 60 cm deep foundation.
- the cabin ceiling comprises a grating, a supply air or fresh air filter lying thereon and, above it, an air duct that directs air from the air drive device
- the object of the invention is to find a cheap spray booth that creates enough good or tolerated air conditions with low energy consumption for a person working in the booth.
- the spray booth comprises a displacement device which makes the object or the vehicle displaceable in the spray booth.
- the displacement device comprises at least one receiving area on which the object or the vehicle rests, in particular with the wheels.
- the receiving area can be moved in the spray booth at least in one direction, the mobility being ensured if necessary by rollers, in particular steering rollers, but preferably by a first guide device.
- the first guide device preferably comprises at least two rails arranged in parallel, in particular running transversely to the longitudinal axis of the cabin, which are fastened to the cabin floor or with their ends to the cabin walls.
- a trolley with rollers or wheels running on the rails is arranged to be movable on the rails.
- the receiving area is optionally firmly connected to the trolley, but preferably a second guide device is formed between the trolley and the receiving area, which makes the receiving area displaceable on the trolley.
- a floor surface can be arranged between the rails which only has to have a low load-bearing capacity and in particular can have an insulation function, so that the heat flow-related heat flow through the floor is minimal.
- the direction of displacement of the second guide device is preferably orthogonal to the direction of displacement of the first guide device, so that the object or the passenger carriage with the receiving area can be moved essentially anywhere within the cabin.
- the vehicle For work on the left or right side of the vehicle, the vehicle is moved so that its right or left side is close to a cabin wall.
- the front or rear of the vehicle can be moved to a cabin wall. The displacement device thus ensures that a sufficiently large work area can be provided for processing each vehicle part area.
- the required cabin width thus essentially results from the sum of a working width required for working and the width of the objects or vehicles to be processed.
- a cabin width of essentially 3 m and a cabin length of essentially 6 m are therefore sufficient for the common passenger cars.
- the cabin cross-section can be reduced to 18m 2 - two thirds of the common cross-section.
- the air throughput at the same lowering speed (0.25m / s) is reduced by a third compared to the known cabins to 4.5m 3 / s or I6'000m 3 / h. This means that in all known circulation processes, that is to say both with complete supply of fresh air and also with the supply of mixed air, the possibility of reducing the cross-section reduces the heating energy or heating power required by a third.
- the receiving area preferably comprises two elongated partial areas or planks, which are spaced apart from one another transversely to the longitudinal axis of the cabin such that the vehicle can be placed on the first or second partial area with the wheels on the right or left side . Since the two partial areas are arranged somewhat above the cabin floor, ramps must be provided, by means of which the vehicle can be moved to the partial areas.
- the displacement device can also comprise a lifting device, so that the vehicle can be raised to facilitate work in the lower area of the vehicle.
- the displacement device offers a further advantage of being able to fasten the exhaust air filter and the exhaust air duct to the displacement device above the cabin floor.
- an exhaust air box with at least one suction opening with the exhaust air filter and the exhaust air duct is attached to the
- the exhaust air box can be displaced with the receiving area at least in one direction, in particular transversely to the longitudinal direction of the cabin.
- the exhaust air box is preferably somewhat narrower than the smallest to be expected
- the vehicle Free space between the wheels and arranged so that the vehicle can be pushed on planks on both sides of the exhaust air box.
- the vehicle can be moved on or with the planks in the longitudinal direction of the cabin relative to the exhaust air boxes. If necessary, the exhaust air box can also be displaced in the direction of the second guide device with the receiving area or the vehicle.
- the suction opening can be designed and arranged as desired. However, it preferably extends essentially over the entire underside of the exhaust air box. If necessary, however, a plurality of suction openings, in particular provided with a closure element, are formed on the edge of the box. This makes it possible to preferentially extract the exhaust air from a certain area of the room.
- a flexible hose connection but preferably a sealed sliding connection, is optionally provided.
- the sliding connection provides, for example, that a connection opening of the exhaust air box is slidable along a slot-shaped connection opening of the air drive device, with a slide device, for example, ensuring that the two adjoining openings are only open in their overlap area.
- a targeted entry of the fresh air is provided.
- at least two, preferably also six, subareas are each connected to the fresh air and fresh air filters, each with a fresh air and a recirculated air supply, the inlet openings of the supply being provided with actuatable closure elements. During operation, these are switched so that each area is supplied with only one type of air.
- One half of the areas is preferably supplied with fresh air and the other half with circulating air, the fresh air areas being selected such that they are each above the current working area. The person working in the work area is thus in a fresh air area.
- the closing elements could possibly be actuated manually by the working person.
- a controller is provided which detects the current working area based on the position of the receiving area or the vehicle or based on the location of the working person or the spraying device and actuates the locking elements accordingly. After the locking elements have been switched over, it takes a period of essentially 15 seconds for a fresh air column to rise from the ceiling to the floor in the new room area. that has built up.
- the control system should therefore only change the work area if the detected work area remains unchanged for at least a comparable time.
- the total fresh air throughput is reduced to 1/3 of the Throughput required for common cab.
- a fresh air throughput of 8,000 m 3 / h already guarantees the same air quality in the work area.
- suctioning under the vehicle ensures a more targeted outflow of the overspray and the released solvents, and accordingly it is also possible to work with a lower lowering speed, for example, at least 0.15 m / s. By reducing the lowering speed to 0.19m / s, the fresh air throughput can be reduced to 6,000m / h to a quarter of the throughput of conventional cabins.
- a preferred heat exchanger comprises two plate modules through which the exhaust air flows horizontally and the fresh air flows vertically. 77% of the heat required by the fresh air can be released from the exhaust air to the fresh air, so that the heating device only has to provide approximately 1/4 of the heat required without a heat exchanger.
- By reducing the fresh air throughput to 1/3 or 1/4 and using the heat exchanger it is possible to limit the heat output to be installed to 1/12 or 1/16 of the heat output of known cabins.
- the effect of a heating line of 300 kW, which is usually provided with burners, can now be achieved with a heating power of 25 kW or 18 kW. Since the usual heating power of 300kW for standard cabins is somewhat oversized, it is in an optimized one
- drying or Burn-in process for which the cabin is heated to temperatures of 60 - 80 ° C.
- the heating takes place essentially by heating the circulating air.
- the fresh air content is reduced to essentially 10% or less.
- an operable duct adjustment flap is optionally arranged in such a way that part of the exhaust air duct together with part of the fresh air duct forms a further circulating air duct in which the heating device and the fresh air Fan are arranged.
- the heating device can also be used to heat the cabin for the burn-in process.
- the heating line required therefore also depends on the desired time within which the drying or stoving temperature is to be reached. It is expedient to have a heating output of a maximum of 50 kW, in particular a maximum of 30 kW, but possibly of 10 - 20 kW.
- This small heating output can be provided with an electrical heating device without the need for special connection cable cross sections.
- the known booths already have connection cables for 40-60 A for feeding the electrical drives of the fans, for the lighting and the electrical parts of the burner, which is also sufficient for feeding the optimally dimensioned electrical heating device. Because the total air flow in a cabin with a smaller cross-section is smaller, the drive motors of the fans can be dimensioned smaller. If three 1.5 kW motors are used instead of three 4 kW motors, these motors already require 7.5 kW less electrical power, which is just enough to supply the electrical heating device.
- An execution orm of the spray booth with an exhaust air box arranged above the booth floor and an electric heating device can be constructed as a plant element essentially on any level floor without any structural measures.
- the fresh air throughput can be reduced by simply introducing fresh air into a small part of the entire ceiling without reducing the horizontal booth cross section and thus without providing a displacement device a range of only 6,000 to 8,000m 3 / h can be brought.
- the partial area or working area that can be ventilated with this throughput is 9 m 2 and corresponds, as stated above, to half the floor space of a cabin for passenger cars with a floor area of 18m 2 .
- the invention thus describes in the most general sense a circulation system for work rooms with minimal fresh air throughput, which in at least one horizontal space boundary area - in the floor and / or ceiling area - comprises at least two separate duct or line areas with closable connection openings to the interior.
- the connecting openings preferably open into evenly distributed, possibly separated from one another in the area of the connecting openings by separating elements, and are separated in particular by filters from the interior.
- at least one connection opening of each channel area is assigned to each room area or can at least be assigned to this.
- the discharged air from each room area can be used as exhaust air and recirculated air, possibly also as recirculated air with different levels of pollution can be discharged separately.
- the circulation in the room can be stimulated from the ceiling to the floor or vice versa.
- a fixedly installed suction arrangement could be provided in addition to the exhaust air box.
- a flat suction according to the state of the art or a linear suction, in particular at least in an edge area between a side wall and the floor, could be provided.
- the permanently installed suction arrangement would extract the less polluted room air and the movable suction opening would be arranged in the current work area in order to extract the heavily polluted air.
- a sliding opening can also be used as a supply opening for fresh air and permanently installed openings can be used as supply openings for circulating air.
- the displaceable suction or outlet openings are preferably moved manually to the respective work area. If you with the object to be processed or a
- Recording area are connected, they do not have to be moved separately. However, it is also possible to provide an actuating device together with a control which ensures that the current working area, as already described, can be detected and the opening can be moved relative to it.
- a circulation system according to the invention can be optimally adapted to the most varied of space and working conditions. It must be decided whether the focus is on the targeted supply of fresh air, the targeted extraction of heavily polluted room air or both. In accordance with this decision, separate duct systems are formed for the supply air or for fresh and recirculated air, for the extraction or the exhaust air and the recirculation air, or for both the supply air and the extraction.
