A back-blowing unblocking device for the dustproof screen of the dryer, a dustproof equipment, and a dryer are provided. The back-blowing unblocking device for the dustproof screen of the dryer utilizes a closed compartment space of the dryer. The back-blowing unblocking device for the dustproof screen of the dryer includes a high-pressure air main pipe, a high-pressure air horizontal pipe, high-pressure air branch pipes, a shunt connecting pipe, and back-blowing fan-shaped nozzles. A length of each high-pressure air branch pipe is equal to a length of an A-shaped dustproof screen. Both ends of the each high-pressure air branch pipe are closed and an upper center opening is welded to the shunt connecting pipe. Both sides of the each high-pressure air branch pipe are densely arranged with the back-blowing fan-shaped nozzles.

A coating material mist remover of the present disclosure includes: a first duct that discharges air containing coating material mist from an outflow port directed downward; a second duct having an inflow port opened in a horizontal direction; and an incinerable intermediate filter that is detachably connected between the first duct and the second duct and removes the coating material mist from the air. The coating material mist remover also includes: a first connection mechanism that can connect and separate the first duct and the intermediate filter; and a second connection mechanism that can connect and separate the second duct and the intermediate filter.

A filter element and multi-component holding assembly for a filter element is provided. The filter element includes first and second media panels, a support frame, a base frame and first and second end cap structures. Each filter media panel defines first, second, third and fourth sides. The first and second sides extend between the third and fourth sides. The support frame maintains the first and second filter media panels in a spaced orientation forming a cavity therebetween. The base frame defines a first opening in fluid communication with the cavity. The first end cap structure seals the third side of the first and second filter media panels and the second end cap structure seals the fourth side of the first and second filter media panels. The base frame has a first portion captured in the first end cap structure and a second portion captured in the second end cap structure.

A livestock facility air filter grid system comprising perimeter vertical and horizontal stiffener plates and interlocking horizontal and vertical field stiffener plates which provides an improved sealed assembly and eliminates the potential for direct air by-pass of the filters.

A filter bank includes a filter enclosure. A first filter panel and a second filter panel are flexibly joined along respective proximal ends of the first filter panel and the second filter panel by a living hinge. A first sealing gasket extends along a distal end of the first filter panel and forms a first air seal within the filter enclosure. A second sealing gasket extends along a distal end of the second filter panel and forms a second air seal within the filter enclosure. A third sealing gasket extends along the living hinge. A pivoting sealing rail pivots within the filter enclosure to form a third air seal against said third sealing gasket extending along the living hinge

A filter module for the separation of overspray from overspray-laden cabin air of coating plants, in particular of painting plants, having a filter housing which delimits a filter chamber through which overspray-laden cabin air can be conducted in a main flow direction. A plurality of separation elements composed of a separation material which is permeable to the cabin air is arranged in the filter chamber such that a flow labyrinth is formed between the separation elements. A separation device and a plant for coating articles having such a filter module is also provided.

A filter assembly that includes a filter housing with a housing interlocking feature, a filter cover with a filter cover interlocking feature, and a filter element with a filter element interlocking feature is disclosed. The filter element is positionable within the filter housing, and the filter cover is attachable to a top portion of at least one of the filter element and the filter housing. The housing interlocking feature, the filter cover interlocking feature, and the filter element interlocking feature are interlockable with each other and extend in a nonplanar configuration along at least one side of the filter element when the filter housing, the filter cover, and the filter element are assembled together.

A filter bank includes a filter enclosure. A first filter panel and a second filter panel are flexibly joined along respective proximal ends of the first filter panel and the second filter panel by a living hinge. A first sealing gasket extends along a distal end of the first filter panel and forms a first air seal within the filter enclosure. A second sealing gasket extends along a distal end of the second filter panel and forms a second air seal within the filter enclosure. A third sealing gasket extends along the living hinge. A pivoting sealing rail pivots within the filter enclosure to form a third air seal against said third sealing gasket extending along the living hinge.

A filter element includes at least first and second opposing pleated media sections and at least first and second support structures supporting, absent an inner liner, the at least first and second media sections and being layered between the at least first and second media sections. In another embodiment, the filter element includes a continuous construction of pleated media forming the first and second opposing pleated media sections, in which the pleats have portions of differing lengths, and a support structure within the interior volume supporting the first and second media sections. The filter element can be in the form of two racetracks, a V-pack, or two V-packs. The racetracks can be polygon shaped.
