The present invention relates to a regenerative transmission device for thermodynamic properties of a main kind of gas body, which is mainly air. The gas is mainly air that forms a primary flow and a secondary flow by heat and moisture, or one of them. Exchanged between two flows of, the transmission device having a rotor, ie a rotor comprising or consisting of a transmission medium having an axially open passageway, the rotor being separated from each other by two gas streams. Passing through the separated zone, a clean outlet part is provided in the transition part from the secondary gas zone to the primary gas zone of the rotating body, The secondary gas reserved in the passage is removed from the secondary gas zone by the primary gas.

The primary gas is composed of fresh atmospheric air, and the fresh atmospheric air is introduced into the space or room for its ventilation, and exchanges heat and moisture with the indoor air consumed in the transmission device to exchange the secondary gas stream. Configure. When a part of the rotor is about to leave the secondary air zone, the passage is filled with consumed air that is not good to enter the room with fresh air and must be blown into the atmosphere with the secondary air.

In the ventilation of a space or a room, the objective is to introduce the same amount of fresh air drawn out from the room into the room. The known structure up to now is the fluctuation of the air distribution occurring in the clean blowout zone when the primary air on one side of the rotor with respect to the axial direction is connected with the secondary air at the opposite end face of the rotor directly through the clean blowout zone. In consideration of this, the amount of air passing through the rotor should be controlled. Calculations can be made to determine the compensation of the fluctuations, but they are relatively complex and uncertain, and the initial and continuous adjustment of the transmitters is quite complex.

One of the main objectives of the present invention is that in order to eliminate this drawback, the outlet and the inlet of the clean extraction passage which discharge to the primary gas zone and the secondary gas zone respectively open at the same cross section of the rotating body, and It is an object of the present invention to provide a transmission apparatus in consideration of a clean takeout device having a clean takeout passage including a clean takeout zone communicated through the rotating body.

Thus, the clean blowout zone is divided into two parts, the characteristics of which are all largely designed, and clean blower air need not be taken into account when balancing the flow of primary and secondary air. If the remaining effective area of the rotor is large in both zones and the input drop in both zones is adjusted to the same value, the same amount of air is automatically passed through the transmission through the zone, resulting in ventilation Equilibrium is obtained with respect to the amount of air introduced into and discharged from the space to be provided. Depending on the actual conditions at hand, each of the two zones of the transmission may be in communication with the fresh air side or with the spent air side. It is only necessary to select the direction of rotation of the rotor so that the clean draw zone is located on the right side between the two zones.

Another object of the present invention is to provide a bearing of a rotating body which is easy to manufacture, can be inexpensive, can be easily assembled and disassembled, and nevertheless ensures the correct position of the rotating body.

Another object of the present invention is to provide a sealing device for a transmission device of the type which is simple in structure and easy to assemble and which does not require any extreme accuracy in the form of a fixed housing surrounding the rotating body for its correct operation. It is.

It is a further object of the present invention to provide a layered rotor that is joined to a part where the layers of the rotor are integrally fixed, thereby enabling the production of a rotor of very large diameter.

The transmission device according to the invention can also be used as a drying device, in which case the primary flow is the air to be dried and the secondary flow is the transmission medium of the rotor, for example the layer of the rotor, It is configured as regenerated air or gas heated to a high temperature to remove moisture collected in the zone.

Other objects and features of the present invention will become apparent from the following description with reference to the drawings.

Referring to the drawings, reference numeral 10 denotes the casing of the transmission device for indoor ventilation as a whole, and the plate 16, so that it can be assembled and disassembled by the protrusions around the periphery of the bolt connection 15 and the end plates 12, 14, It consists of two parallel plates 12,14 joined together by 18. These end plates are provided with circular openings 19 (FIG. 1), which are installed opposite to each other and subdivided into sectors by spokes 20, and the number of spokes is four and in the embodiment shown in FIG. It is distributed at an angle of 90 degrees.

In the illustrated embodiment, the opening is divided into two equal halves vertically so that one half of the passage passes through the fresh air that intrudes and the other half passes through the spent indoor air that is discharged. The end plates 12 and 14 are rigidly fixed with tubular connecting jackets 22 and 26 so that the jackets are connected to the thread or space and the atmosphere and to the conduits guided therefrom. This type of tubular jacket 22 integrated with the end plate 14 connects the transmission to the room or space to be vented and is displaced by the air consumed in the direction of arrow 24 (FIG. 2). The other end plate 12 bears on the jacket 26, which forms a continuous passage or zone for the spent air, ie secondary air. Fresh air is directed through the jacket 28 to the transmission, where it passes through the jacket 30 and into the room. These tubular jackets are preferably long quadrilateral as evident in FIG.

A rotor, or rotor 32, is provided in the space enclosed by the single plates 12, 14 and the plates 16, 18, the rotor being a hub 34 and a narrow gap, ie a passage, disposed from the end to the end in the axial direction and extending from end to end. It is provided with the annular body which forms the layer. A strip 36 is provided on the outer circumference of the annular body. The form of the layer will be described in detail below.

The hub 34 is attached on the bearing shaft 40 by two ball bearings 38 (FIG. 4), the shaft 40 having only one end fixed to one end plate 14 and for this purpose the spoke 20 of the end plate being circular. Single wall 42,44 and square flange 43 are connected to central plate 41. The bearing shaft 40 is rigidly fixed to the circular plate 45 and the circular plate is fixed to the short side 44 when the bolt 48 penetrating the center plate 41 is fitted to the shaft 40.

The hub 34 can be adjusted in the axial direction with respect to the axis 40 by means of a sleeve 46 movable with respect to the bearing. The sleeve 46 is fixed in the desired position with screws 50 relative to the spaced sleeve 49 attached between the two bearings, which are accessible from the outside through an opening 51 provided in one end wall of the hub 34. Retaining ring 52 is screwed to shaft 40 on the outside of outer ball bearing 38.

This bearing arrangement makes it easy to install and detach the rotor 32. The rotating body is fixed or separated in the operating position as one screw. Since the end wall of the hub 34 does not protrude or only slightly protrude from the end face of the plate of the rotor, the rotor can be introduced into and removed from the casing 10 by removing the plate 18 on one side of the casing 10. . Supporting only one side of the rotating body has the effect of holding a constant position with respect to the short wall where the axis of the rotating body is always fixed. A slight movement of the two end walls between transports or installations of the transmission device does not cause the motor to jam and incline enough to cause a malfunction.

Between the edges of the rotor 32 and between the two zones formed in the transmitter arrangement, a sealing member, most clearly shown in FIGS. 3 and 5, is arranged. The sealing member is fixed on the end plates 12 and 14 and cooperates with the transverse plane formed by the layer of the rotor 32. 3 shows a sealing strip 54 supported by a flange 60 fixed to one end plate, such as the end plate 14, by means of elastic fasteners 56 and screws 58. FIG. Seal strip 54 is made of cork, fiber asbestos, plastic and other suitable materials. This is held in a predetermined position by the mutually spaced elastic fasteners as shown in FIG. 1, and has the possibility of moving to some extent in the fastener when the rotating body is installed. When the rotor 32 is attached in place in the casing 10, the strips 54 can be inserted into their fixtures 56, but can then be retractably moved to the side of the plane of the rotor. To resiliently mount, strip 54 can automatically form itself according to the inevitable tilting position or similar irregularities of the rotor, so that the strip is somewhat along the perimeter of the pole and the radial bulkhead. It is sealed against the rotor for a reason.

The direction of rotation of the rotating body preferably coincides with arrow 62 in FIG. 3, so that the strip can be bent with the fixture 56 being used as a spring if it comes into direct contact with the rotating body during operation of the transmission. Thus, the strip 54 is prevented from being damaged or damaging the layer of the rotating body.

The rotor 32 is rotated by an electric motor 64 which drives a pulley 68 through the reduction gear 66. The belt 70 is provided around the cylindrical strip 36 of the pulley and the rotor. In a transmission device for ventilation purposes, the rotational speed is about 10 revolutions per minute.

At the side of the rotor, a center plate 41 having a relatively narrow spoke 20 is provided which separates the flow path formed by the passages 26 and 28 from each other up and down, and the spokes are sealed in FIG. Holding the strip 74, the strip is joined by a semicircular strip portion 75 along the flange 43 of the center plate 41. On the lower opposite side of the center plate 41, a similar narrow spoke 20 co-operating with the sealing strip 76 is provided. However, on the axial side of the rotor, the spokes 78 are fan-shaped and the same type, the same size portion extends through the periphery of the vertical spoke 20 on the other side of the rotor.

The flat spokes, i.e. the partition member 78, cooperate with the two sealing strips 80,82, which are joined with each other and the lower sealing strip 76 by the semicircular strip portions 84 held by the center plate 41. Two clean outlets are thus formed between the two flow sections in the transmission. When the rotor 32 rotates in the direction of arrow 62 (third degree) and the left portion formed by passages 22 and 26 passes through the air of the consumed room at sunrise, the heat and moisture displayed therein are due to the layers of the rotor (winter conditions). For the purpose of this), it is accepted as if it is discharged into fresh air flowing through the rotor as a countercurrent through other parts of the transmission. When the layer of rotor is finally passed through the zone of fresh air, it is not desirable for the indoor air in the space of the rotor to enter the room with fresh air coming in according to arrow 86. When fresh air reaches a zone of fresh air and this fresh air flows through the gaps to remove the air consumed in the gaps and deviates through the passage 26 with the consumed air, it is clean to introduce fresh air into the rotating body gaps. It is the purpose of the takeout part. At the clean outlet, the air first flows in the direction of arrow 88 at intervals 92 surrounded by strips 80 and 82 of the inside of the fan-shaped spokes 78, then changes direction and exits into passage 26 with the spent air. Therefore, return to the other half of the clean outlet.

By this type of clean blower, the amount of air exiting the ventilated chamber and the amount of air introduced are passed through the transmission apparatus without being quantitatively changed by the presence of the clean blower. Therefore, the drop in pressure in the flowing zone can be used as a direct measure of the amount of air volume considered, which allows simple adjustment and control of the amount. This is especially important when the pressure levels at the primary and secondary air sides are significantly different.

The sealing device has annular strip portions 94,96 which are tensioned around the circumferences on both sides of the contact insert of the rotor 32 so that the leakage by this method is effectively eliminated.

The sealing device of the present invention, which is an axially movable, easily accessible and adjustable sealing strip, does not need to be mounted with a fixed part of the transmission device processed to an extremely high degree of precision. The difference resulting from the flow between the rotating body and the sealing strip with the holding plate portion is thus equalized in a simple way when the sealing strip is finally adjusted relative to the rotating body.

The contact insert may consist of a thin layer or a plate, for example by the method described in US Pat. No. 3,231,409. The layer forms a narrow axial gap or passage extending from one end to the other end, so that the layer is flat and corrugated or corrugated with each other, and the height of the corrugation is low as 1-3 mm. These layers can be made of asbestos, as described in the above patents, which are infused with a hygroscopic material, for example lithium chloride.

The insert of the rotating body 32 is configured as a sector 98 (FIG. 1), which can be obtained from a material having the form of a rectangular material 100 as shown in FIG. These materials are made of integrally fixed layers parallel to each other and are cut into two equal parts 100a and 100b along line 102 but they are contoured in parallel, i.e., a peak paragonal quadrilateral, the latter The portion 100b of is inverted to the position of 100c, where the portions are joined together. The outer and inner edges of the overlapping material are machined into cylindrical shapes along 32a and 46a, respectively. Here, the discarded portion is small as evident in the figure. The fan-shaped materials are bonded to each other by a suitable adhesive such as epoxy resin.

In this way it is possible to make a rotor with a very large diameter. Since the directions of the layers in the respective fan-shaped materials are different, the tendency to form a split between the two layers along the surface direction of the layer is significantly reduced.

Since the exchange of heat and moisture is achieved by the transmission device of the present invention for ventilation purposes, the heat contained in the discharged indoor air is cooled in the main part which is converted into the incoming relatively cold fresh air. In addition, the rotor collects moisture from the exhaust air released into the incoming air, which is important to keep the indoor air from humid, especially in winter.

The apparatus of the present invention can be installed so that most of them can be used as a drying apparatus, the purpose of which is to dry the air by the high temperature regeneration air stream of 100 ℃ or more. In this case, it is important that the rotating body can be easily separated and that the sealing member is mounted in such a manner that it can be easily adjusted.

In the case of a dryer, the area of the regeneration zone is one part, for example one quarter, of the zone of the primary air. It may happen that the primary air flow and the secondary air flow are in different amounts. Also in this case, it is important that there is a possibility that the amount of flow can be measured or that the amount can be adjusted to a desired amount as an easy method provided by the present invention.

While embodiments of the present invention have been shown and described, it is merely exemplary and the present invention is not limited thereto and particularly includes all without departing from the scope of the claims.
