Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a device consisting of a double-cooled fan part as housed in a pipe utilizes the full capacity of the fan part to create a fixed predefined feature or suppression at the top of chimneys and exhaust systems with simultaneous dilution, ejecting and spreading of smoke or contaminated air without the penetration of the fallout. in connected feature applications.

The device is of the type mounted on top of or in chimneys and extractor systems, consisting of a pipe of a diameter approximately corresponding to the external dimension or size of a chimney or extractor system, straight or curved, material, shape and color and as inside is lined with a thin damping material in which a double-cooled fan part is disposed. '

Exodraft.RSV is known to have a speed regulated device which, however, has the disadvantage that no fixed predefined feature is obtained, utilization of the full capacity of the device for diluting or spreading smoke or polluted air when the speed of the engine can be arbitrarily adjusted according to user needs. It is also a clear disadvantage that the device known by Exodraft RSV is mounted on a mineral wool mat placed between the device and the chimney stop, which prevents air from entering the device to dilute the smoke. It is also a clear disadvantage that the The Exodraft RSV known device alone is not designed to create a fixed predefined feature without connecting external accessories in the form of a measuring and control unit for controlling the feature, which is a clear disadvantage that dilution cannot be done without mounting additional accessories in in the form of a retrofitted flange at the top of the chimney and the mounting of spacer bolts, so that false air is fed into the device. to create the highest possible dilution and dispersion.

On the device known by Exodraft RSV, axial wings and engine part are separated by a plate whose purpose is to prevent overheating of the engine from the rising hot flue gas, as well as shield the engine in a motor housing which is cooled directly by outdoor air through small openings in the sides. The size of the plate covers an area larger than the area of the axial wings just above the smoke or air flow. The position of the plate over the axial vanes results in a relatively large loss of capacity. The axial blades are made of a weight-heavy construction, which results in a relatively high demand for engine power.

Considering that in order to provide the necessary capacity to achieve both drag, dilution and spread, and in order to operate a weight-heavy axial blade, it is necessary to use a device with a motor larger than intended, it is a clear disadvantage that it causes a multiplication of energy consumption.

With the well-known devices from Kutzner und Weber, Injekt and Termatech which use the ejector principle to throw smoke into the air, it is a clear disadvantage that the construction due to the open top is not designed for mounting on chimneys or exhaust systems where must not penetrate the precipitation rainfall in connected feature applications. Considering that a large number of wood-burning fireplace users are just plugged directly into the bottom of a steel chimney, it is a clear disadvantage that fallen rainfall can cause fireplace destruction. There are, however, post-mountable accessories in the form of a rain cap, which is placed over the top of the devices, so that the precipitation does not penetrate into connected functional applications, but it is a clear disadvantage that the devices cannot simultaneously apply the ejector principle with vertical return, since the rain cap at its location over the top prevents the intended ejector action of the devices. With the speed control device known by Kutzner und Weber, Injekt and Termatech, it is a clear disadvantage that a fixed predefined drag and full capacity of the device for dilution or spreading can not be achieved when the speed of the engine is arbitrarily adjusted according to user needs.

By the device known from US 564583 A intended for mounting in exhaust ducts from kitchens and similar extractors designed to create in operation an air flow in the axial direction of the pipe, with dilution of cooking odors through lateral openings calculated in the total area of Given the area in the opening of the hole in the roof, it is a clear disadvantage that the device is not designed to be used at the top of a chimney with consequent requirements for features from connected functional applications and prolonged temperature and precipitation loads, which is supported by the fact that the side ventilation apertures not in dimensions are calculated to create a fixed predefined feature or vacuum in a chimney or exhaust system based on normative requirements from or for connected functional applications. It is a clear disadvantage that the device known in US 564583 A in description and function is limited only to applications for extraction systems from kitchens where there are no high temperatures in toxic gases or in smoke. It is a clear disadvantage that the device cannot be used for chimneys or exhaust systems whose primary function is to dissipate hot flue gas or polluted air containing toxic substances. It is also a clear disadvantage that the device known by US 564583 A causes direct poisoning danger to creatures residing in rooms with functional applications developing toxic gases connected to a chimney or exhaust system in which the device known by US 564583 A is located at the top. . If the crescent-shaped covers arranged as a two-piece lid at the top of the device intended to prevent rainfall from falling into the device, get stuck, do not open due to defective electromagnet, power failure or snow on the top of the plates, it is a clear disadvantage that the construction can cause poisoning death for creatures residing in the building, since the device known by US 564583 A will, under these conditions, act approximately as a plug at the top of a chimney or exhaust system, causing the risk of poisoning. Thus, it is a clear disadvantage that the device is not suitable for placement on or in chimneys or exhaust systems that divert harmful health smoke or air.

Thus, there is a need for a fixed feature, dilution, vertical spread, precipitation and energy utilization of a contemporary smoke and contaminated device that meets environmental, utility and safety requirements and design requirements.

The invention thus relates to a mechanically double-cooled · draft smoke regulating device for hot smoke and polluted air intended to create a normative draft in chimneys and exhaust systems where draft or vacuum is unstable / poor, and in operation to create a mixture of air / hot smoke or contaminated air and dilute hot smoke or contaminated air and spreading them upward in the atmosphere axially longitudinally of the pipe from a chimney or exhaust system comprising one pipe in which is mounted a double cooling unit with a fan part, hereinafter called the cooling unit / fan part .

The device according to the invention can be mounted on top of or integrated into chimneys or extraction systems, and consists of a double-cooled fan part arranged internally in a pipe of a size approximately corresponding to the external dimension, material, curved or straight, shape and shape. color, which is lined with a thin resonant damping material. The fan part / cooling unit can as a separate part be built into foreign chimney / extractor systems and functional applications.

The tube is made of metal or other suitable material. The tube may have a shape that is approximately round or angular, curved or straight, so that the unit can be adapted to all chimneys and exhaust systems.

At the top of the pipe is a cooling unit / fan part in which a motor is mounted. In the cooling unit / fan part are placed cooling radiators which at the outward end are greater than or equal to the pipe and at the inward end · in the cooling unit / fan part end in one air intake above or at the engine.:The motor is fixed in an inner cup with downward shaft through which the shaft is passed out through a cooling hole at the bottom of the inner cup. Under the inner cup is mounted a centrifugal blade of a dimension approximately equal to the diameter of the bottom of the inner cup, and a height approximately equal to the centrifugal wing plus the required working clearance height between the top and bottom of the inner and outer cup. The inner cup containing the engine and centrifugal blades located externally is placed down into an outer cup, a size that allows the required amount of cooling air to pass between the bottom and sides of the inner and outer cup, and out through the top of the outer cooling cup via a gap below the top flange of the inner cup and the outer cup. Under the outer cup through a hole in the bottom of the shaft, at the end of the shaft is mounted on a holder an axial wing.

Under the cooling unit / fan section, the lower part of the stirrup is open, where a safety grid or one or more conductor plates, for example, is placed under the cooling unit / fan section. in the form of a set of round inwardly facing upwardly directed rings with an inner diameter corresponding to an inside dimension of the chimney and an outer diameter corresponding to the outer dimension of the pipe on the device. The rings are upward with varied slopes in relation to the effect, but will preferably be approx. 45 °.

Under the axial wings is mounted a heat shield placed in struts resting in adjustable or fixed holders on the inside of the pipe, on the flange or on the rings. The pipe is mounted on a fixed or interchangeable flange mounted on a downward-facing pipe in a dimension which can be passed down into any common chimney or extraction system by means of fitting rings. The hole in the flange can be adjusted so that the draft in the chimney or exhaust system can be adjusted as needed.

The invention provides a near-invisible device which is designed in size shape and color as a natural part of, or in a steel chimney, or which a less visible part design in size, shape and color as a natural part on or in a brick wall chimney or fan system, which device can easily regulate proper drag or suppression from the requirements of a functional application by a manufacturer or authority. Flue gas or polluted air is diluted and blown to the top for greater dispersion in the atmosphere. Due to the design and choice of intelligent motor control, energy consumption is very low. Fallen rainwater cannot penetrate into the chimney or exhaust system and cause damage to connected functional applications. In the case of hot flue gas or polluted air mixed with the air, the temperature branch around the cooling unit / fan part is significantly reduced and due to the design of the cooling unit / fan part the engine temperature is further reduced to an acceptable level of operation for the engine. In order to prevent overheating of the engine in the absence of manual start-up, one or more sensors that start the engine when the temperature exceeds a given temperature are placed as motor protection in the cooling unit / fan part. The same sensor (s) start the engine when the smoke or air thinner is heated to a given temperature by strong sun exposure, so that critical engine parts outside normal operation are cooled to an acceptable temperature level which extends the engine's service life.

This is achieved in accordance with the invention by using materials, sizes, shapes and colors in design and construction that are adapted to the chimney or exhaust system the device is to be mounted on or in. Functionally, the invention is characterized in that at the top of the pipe, mounted in a top ring , arable is a cover that prevents birds from falling into the tube and prevents contact with rotating end parts. The top ring with shielding is mounted on a short chain or wire which is attached to the outside of the pipe, into which the top ring with nets can hang in when servicing.

Underneath the grid, the cooling unit / fan part may be attached to the tube with vibration absorbing absorbers attached to the tube, or the cooling unit / fan part is attached to the shield which is suspended from the top of the tube. The power cable from the motor part is fitted with a service multistory with 'possibility of connection' of one or more control, measuring or sensing units in the cooling unit / valve adapter part. The control, measuring or sensor units are located at one or more critical or strategic locations in the cooling unit / fan section. The voltage cable is passed through one cooling pipe and down the pipe to a protective circuit breaker which switches off the motor when the device is to be cleaned or maintained or is connected to terminals of one or more cooling tubes, the purpose of which is to disconnect the power when the cooling unit / fan part is lifted free of the connectors in connection with service. Underneath the cooling unit in the ventilation openings is a grid or baffles in the form of adapted inwardly facing upward rings having an inner diameter approximately equal to the inner dimension of the exhaust pipe and an outer diameter approximately corresponding to the outer dimension of the pipe greater than or equal to. The rings direct the dilution air into the smoke or contaminated air column coming from the top of the chimney or exhaust system and up to the fan section, as well as draining down rainwater. The device is fixed to a fixed or interchangeable flange mounted on a downwardly directed pipe in a dimension which can be passed down by means of fitting rings in all common sizes of chimneys or extraction systems. Underneath the device abutting the top of the chimney or exhaust system, a vibration damping material / seal ring is applied which reduces resonance, vibration and penetration.

Functionally, the invention is characterized in that the cooling air of the cooling unit is sucked in through one or more adjacent cooling pipes and into an air intake in which the upper part of the motor housing is located. The cooling air cools the motor housing, then is forced downwards between the outer sides of the motor housing and the wall of the inner cooling cup. The cooling air is further passed below the engine housing, through an opening at the bottom of the inner cooling cup, and into the outer cooling chamber where the cooling air centrifugal blade applied to the motor shaft forces the cooling air into the gap below the bottom of the inner cooling cup and the bottom of the outer cooling cup, and up the sides of the outer walls. inner and outer cooling cup. The cooling air then flows horizontally into the space between the inner and outer cooling head top flange at the top during the air intake and into the mixed atmospheric air / smoke or polluted air coming from the axial wing under the cooling unit / fan section. The special design of the cooling unit / fan part and the choice of intelligent engine type make the cooling unit / fan part fit different sizes of pipes, thereby changing the total unit capacity and energy consumption by simply extending cooling pipes and replacing the axial blade size depending on the requirements / size of chimneys and extractor and / or requirements for connected function applications.

In one embodiment, the top of the device is configured as a nozzle to increase the rate of return approximately as an ejector effect and to minimize the amount of precipitation.

In another embodiment, the ventilation openings in the dilution air duct under the fan part / cooling unit are expanded by a separate portion consisting of a mesh, grille or set of inwardly facing upwardly inner rings: approximately corresponding to the inner dimension of the chimney or extractor system and an outer diameter corresponding to the external dimension of the device greater than or equal to.

In a third embodiment, the cooling unit / fan part is arranged below the suspension (upside down), where the engine part is fixed in a single or double cooled cooling unit / fan part with cooling tubes which simultaneously act as legs placed on / at the flange or hanging end of the pipe.

In a fourth embodiment, the upwardly extending rings below the fan portion are attached to the outer side of the tube with an inner diameter corresponding to the outer dimension of the tube and an outer diameter corresponding to the outer dimension of the tube being greater than or equal to.

In a fifth embodiment, before and / or after the ventilator portion, a filter device is provided for the purpose of purifying the flue gas or polluted air for undesirable items. The filter device is made of metal, ceramic material or polymer material suitable for the purpose. Likewise, the pore or mesh size of the filter may be varied depending on the purpose, just as a liquid bath, an electrostatic or ion exchange application may be included as a filter.

In a sixth embodiment, there are arranged two fans in the unit, between which are arranged a filter device, the purpose of which is to purge the flue gas or the polluted air from blanks.

In a seventh embodiment, sensor and measurement technology applications for control, registration, notification, security, logging and communication are mounted.
