Definitions

  • the invention relates to a protective device for spinning plants, in particular with regard to possible fires and / or explosions.
  • Flammable or combustible material such as cotton is processed in the spinning mill.
  • processing elements for example garnished rollers
  • transport elements for example pipes
  • Flying sparks are also possible due to, for example, metallic foreign bodies or stones, which can lead to smoldering or even igniting of the combustible materials, and this at a point in the direction of transport behind the actual spark formation. If these materials are good fibers, they experience a deterioration in color due to the sooting that is caused, which leads to undesirable rejects. If the materials are waste that has been carried along (e.g. fiber knots), i.e. foreign parts possibly with contained fiber material, this can lead to explosions similar to a flour dust explosion, especially in the case of waste bags, which is an enormous risk of injury Represents people in the vicinity.
  • the object of the invention is therefore to counter these disadvantages.
  • the invention provides a device which has at least one sensor which responds at least to a predetermined fire gas.
  • fire gas is a gas that gives an indication of smoldering or even burning material.
  • the sensor is designed to be used on or in a section of a spinning plant in such a way that a detection section of the sensor is oriented towards a cavity of this section to be detected. Detecting the presence of fire gas has the decisive advantage that the time delay for detection is generally much shorter than with a temperature sensor. In other words, the sensor responds much earlier. For example, the aforementioned explosions can be avoided or people can be warned, for example, by means of an alarm device. Even the risk of damage to machines in the spinning plant is reduced. Last but not least, there is significantly less waste in the case of smoldering good fiber material.
  • the detected fire gas preferably comprises carbon monoxide.
  • a sensor which reacts to carbon monoxide has the advantage that this fire gas is already produced before a fire (or an explosion) occurs. This fire gas already arises when the combustible material begins to smolder. Additionally or alternatively, the fire gas includes carbon dioxide as a second, relevant gas that arises during smoldering or burning. This increases the flexibility of use.
  • the device according to the invention preferably further comprises a holding section.
  • the sensor is attached to the holding portion.
  • the holding section for its part, is designed on the aforementioned section of FIG Spinning plant to be attached.
  • the holding section thus forms a type of adapter which can accommodate the most varied of sensors and which is itself structurally matched to the respective section of the spinning plant.
  • the section according to the invention comprises a transport section designed to transport material within the framework of the spinning mill processing.
  • Such transport sections can be transport pipes, a mixing belt and the like.
  • the section comprises a collecting section designed to collect material in the course of the spinning mill processing.
  • Such collecting sections can be a waste container and a mixing chamber.
  • the section comprises a processing section set up to process fiber material.
  • Such sections can be, for example, carding sections, drafting system sections, cleaner sections, winding sections, combing sections, gates, can depositing devices, flyers, spinning machines, material lines, waste lines, exhaust air lines.
  • every area of a spinning plant can be equipped with the device according to the invention; it is universally replaceable.
  • FIG. 1 a cleaner with a device according to an embodiment of the invention
  • FIG. 2 shows a transport tube 2 provided with a sensor 8 according to the invention.
  • FIG. 2a shows the arrangement formed in this way in an exploded view.
  • FIG. 2b shows the arrangement as it arises for an observer.
  • FIG. 2c shows this arrangement in a vertical longitudinal section through the center of the tube of FIG. 2a.
  • FIG. 3 shows a spinning machine 1 in the form of a bale opener.
  • a milling head 14 has impact rollers 15 on its underside in a known manner.
  • This transport pipe 2 is provided with a suction device which transports away the fiber material detached from the beater rollers 15 in the direction of a perpendicular pipe 2 arranged here on the right.
  • sensors 8 which are aligned in the direction of impact rollers 15. This makes it possible to detect when the fibers are detached from a bale 22 if the beater rollers 15 are running too fast, for example, and thus lead to excessive heating of the detached material or even to the formation of sparks.
  • each mixing chamber 16 there is an arrangement of rollers which, as a whole, form a roller mechanism 20.
  • the conveyor belt 18a On which the fiber material from the mixing chambers 16 is deposited, preferably in layers. This layered fiber material is led out of the mixer 1 via the conveyor belt 18b arranged next to it on the right.
  • a sensor 8 is preferably arranged in each deflection section 17, which in the open state (left mixing chamber 16) is directed in the direction of the fiber-material flow. In the closed state (other mixing chambers 16), the respective sensor 8 is directed in the direction of the transport path over the mixing chambers 16. This makes it possible to be able to check material located in the upper area of the mixer 1 for possible combustion gases. Also in the left A sensor 8 is preferably located in the upper deflection area of the pipe 2.
  • an extinguishing device 9 which is activated when a fire gas is detected for the respective mixing chamber 16.
  • an air pipe 19 To the right of the right mixing chamber 16 is another air pipe 19 through which excess air can be removed from the fiber material.
  • a sensor 8 At the exit of the mixer 1 at the bottom right there is also an arrangement comprising a sensor 8 and an extinguishing device 9. This makes it possible to also check at the exit of the mixer 1 whether or not combustion gas is occurring.
