Publication number: 20240058733Abstract: A filter system including a filter housing with an inlet part, a clean-gas outlet, and a partition wall defining a product chamber and a clean-gas chamber. The partition wall having openings from which filter elements extend downward into the product chamber. The inlet part is placed in an upper part of the product chamber and configured for supplying a product-containing flow of gas to the product chamber. The gas flow being conveyed through the filter elements and into the clean-gas chamber, where the filter system is provided with an air or gas supply placed in the product chamber and configured for leading drying air or gas into or out of the filter system. A method of drying filter elements in a filter system by passing drying air or gas through a filter inlet and/or through a drying air or gas supply.Type: ApplicationFiled: December 17, 2021Publication date: February 22, 2024Applicant: SIMATEK A/SInventor: Arne Grønbæk JENSEN

Patent number: 9254458Abstract: A filter including a filter housing with a horizontal partition wall dividing the filter housing into a dean-gas chamber and a dust chamber. The filter has an inlet part in open communication with the dust chamber. The inlet part is configured for supplying a dust-containing flow of gas to the dust chamber. The gas flow is conveyed through the filter elements and upwards into the dean-gas chamber where the filtered gas is discharged through a clean-gas outlet. In the filter housing, a cylindrical inner portion is arranged that encircles the filter elements. A round-going inlet part is opposed to the cylindrical inner part. The round-going inlet part has a larger diameter than at least a portion of the filter housing that adjoins the inlet part. Gas flow is divided into an upwardly and downwardly oriented gas flow controlled by arrangement of the cylindrical inner part.Type: GrantFiled: March 8, 2013Date of Patent: February 9, 2016Assignee: SIMATEK A/SInventors: Arne Grønbæk Jensen, Christian Dan Andersen

Patent number: 7563295Abstract: A filter including a filter housing with an essentially horizontal partition wall that divides the filter housing into a clean-air chamber and a dust chamber. The partition wall is provided with a number of apertures in which a number of filter bags are provided that are secured to the partition wall and extend down into the dust chamber. The filter is provided with an inlet portion in open communication with the dust chamber in a level that is above a lowermost end of the filter bags, wherein the inlet portion is configured for introducing a dust-containing flow of air into the dust chamber, from there it can be sucked through the filter bags and up into the clean-air chamber, from where the filtered air is discharged through a clean air outlet. A number of diffuser elements are arranged in the inlet portion outside the filter housing.Type: GrantFiled: February 5, 2004Date of Patent: July 21, 2009Assignee: Simatek A/SInventor: Christian Andersen
