Definitions

  • the invention relates to a highly efficient internal circulation dust removal system.
  • This invention relates to the technical field of dust removal systems and more particularly to a highly efficient internal circulation dust removal system.
  • bottle caps are pressed onto the bottle openings in a bottling machine.
  • the bottle cap is generally placed in the hopper of an automatic or semi-automatic capping machine, and then conveyed to the upper entrance of the filling machine by a conveyor, and it is difficult to avoid that the bottle cap in the capping machine or conveyor directly comes into contact with air.
  • the bottle cap comes into direct contact with air in the production and packaging process, so that the dust from the air sticks to the inner and outer surface of the bottle cap.
  • the bottle caps are usually packed in cardboard boxes and in the cardboard boxes again in plastic bags.

  • the present invention effectively solves the problem of difficult and incomplete dust removal through internal circulation, improves food hygiene and safety, helps consumers to have healthier foods, and ensures consumers' health.
  • the internal circulation dust removing device has promising development prospects in the canning industry, as well as representativeness and wide application perspective, and greatly enhances the food safety reputation of enterprises. Since gas or a gas mixture, in particular air, circulates internally in the dust removal device, the dust that is thrown up is not blown into the ambient air. Instead, it is collected in the dust filter and dust collection bin. The filtered air freed from dust by the dust filter and dust collection container can be used again for cleaning. This creates a cycle. There is therefore no need for lines that have to transport the dust-laden air away.
  • a filter net is arranged at the connection point of the hopper to the dust suction pipe, and a mesh chute is arranged inside the hopper.
  • a chute suction opening is arranged at the top of one side of the hopper, the chute suction opening being matched to one end of the dust suction pipe, and at the bottom of one
  • An air inlet opening is arranged at the end of the hopper, the air inlet opening being matched to one end of the air discharge tube.
  • pipe clamps are attached to the two ends of the dust intake pipe, to the two ends of the air intake pipe and to the two ends of the air discharge pipe.

  • a sealing ring is firmly connected to each of the two inner ends of the filter container cover.
  • the dust removal system can also be realized without being connected to a vertical conveyor or to a hopper.
  • the dust removal system of the present invention can also be used to remove dust or other contaminants in other facilities.
  • the dust removal system according to the invention can be used in particular for cleaning the containers themselves.
  • the dust removal system according to the invention is not limited to this application either.
  • the dust removing system may include the fan outlet pipe joint and the dust suction pipe, but not the hopper connections as described above.
  • the fan outlet tube connector and the dust suction tube can then be connected to the connections required in an application and/or to the nozzles or other devices required for the particular application.
  • a dust removal system with internal circulation can be designed for connection to a conveyor device or a container to be cleaned and characterized in that a dust suction pipe of the dust removal system is firmly connected to an upper part of a dust filter and dust collection container, the upper part of the dust filter and dust collection container via a Air intake pipe is fixed to a fan inlet pipe joint located on one side of a fan, an air discharge pipe is fixed to a fan outlet pipe joint located at the bottom of one end of the fan, the dust filter and dust collection box includes a filter box body, a bag support frame fixedly connected to the inner upper end of the filter container body, a filter bag is slipped over the outer surface of the bag support frame, the top of the filter bag is connected in a wrapping manner to the bag-wrap opening located at one end of a bag cover, between the top of the filter container body and a sealing tape is arranged at the other end of each bag cover, and a filter case lid is pinched to the top of one side of the filter case body via a fastener.
  • the dust removal system can be formed as a transportable unit. This makes it easy to move to a job site. This is particularly easy since the dust removal system works with internal circulation and therefore there is no need for ducts that have to transport the dust-laden air away.
  • the dust removal system can be provided with rollers.
  • the dust removal system can have at least one ionization device for ionizing a gas or gas mixture circulating in the dust removal system.
  • the ionization device can be located behind the dust filter and dust collection container or behind the fan.
  • the filtered gas in particular the filtered air
  • the filtered gas can pass through the ionization device and be ionized.
  • ionized air is suitable for removing the smallest parts, including bacteria and viruses.
  • the ions in the air can bind to these parts, making them lighter can be moved by the air flow. Therefore, the ionizer dust removal system can be used to remove pathogens from containers, closures, or other items.
  • the dust removal system provided with at least one ionization device can be used like the above-described embodiments of the dust removal system, but at the same time increases the effectiveness of the cleaning.
  • an advantage of the internal circulation comes into its own. Because the dust removal system is a closed system with internal circulation of the gas or air, it is possible to prevent the ozone produced during ionization from getting into the ambient air. There may be limit values for the ozone content of air, in particular limit values relating to occupational safety.
  • the dust removal system with at least one ionization device and internal circulation is advantageous because the ozone content of the ambient air of the dust removal system is not increased or only increased to a small extent because of the closed design.

  • the gas or gas mixture can in particular be air.
  • the suction device can be designed, for example, as a funnel or a tube.
  • the suction device can be placed on a container in such a way that the container is closed by the suction device.
  • the pressure nozzle can then blow a gas, in particular the air filtered by the dust removal system, into the container. At the same time, the air can be sucked out by the suction device. Dust or other parts thrown up in the container can thus be sucked off by the suction device and filtered out by the dust removal system.
  • the pressure nozzle can protrude from the suction device, so that the pressure nozzle is arranged closer to the bottom of a container to be cleaned than an end of the suction device with which it bears against the container.
  • Filtered air in particular filtered and ionized air, can be blown into the container from the pressure nozzle. Any dust or other contaminants in the container can be whirled up by the air and sucked off by the suction device. If the air is also ionized, the interior of the container can be cleaned particularly well.
  • the pressure nozzle can be connected to a pressure line.
  • the pressure line can be routed to the outside through a wall of the suction device.
  • the pressure line can be connected to the outlet pipe connection of the blower.
  • At least one ionization device is preferably located between the blower and the pressure nozzle in order to ionize the air before it is blown into the container.
  • the dust removal system may include a High-Efficiency Particulate Air (HEPA) filter that can remove minute particles from the circulating air.
  • HEPA filter can be located in the dust collection container. This allows the smallest parts in the airflow, including bacteria or viruses, to be filtered out of the air.
