Utility Model Content

[0003] The utility model aims to provide a two-stage air separation dust removal processing structure for a foam crushing dust removal machine to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] See also Figure 1-4 ,

[0020] The secondary air separation dust removal processing structure for the foam crushing dust collector includes a primary air separation dust removal component 1 and a secondary vortex cyclone filter device 2 connected to the primary air separation dust removal component. The primary air separation dust removal component includes a tank body 3 arranged in a negative pressure chamber, a filter window 4 is arranged on the side wall of the tank body, and a filter screen (not shown) is arranged on the filter window. It also includes a feed pipe 5, one end of the feed pipe is connected to the discharge end 6 of the crusher through the first fan, and the other end of the feed pipe extends into the tank body to form a feed port 7, and a material screening chamber 8 is formed between the outer wall of the feed pipe and the inner wall of the tank body. A controllable air suction device is arranged on the bottom of the material screening chamber, and the controllable air suction device is connected to the secondary vortex cyclone filter device. The material after dust removal by the primary air separation dust removal component is sent to the secondary vortex cyclone filter device through the controllable air suction device for secondary air separation dust removal. Among them, the secondary vortex cyclone filter device has been disclosed in the Chinese patent foam crushing dust collector with application number CN202211743722.7, and will not be repeated here.

[0021] In this embodiment, the controllable air suction device includes an air inlet 9 and an air suction port 10 connected to the material screening chamber. The air inlet is connected to a second fan 11, and a damper 12 is provided between the second fan and the air inlet. One end of a third fan 13 is connected to the air suction port, and the other end is connected to a feed end 14 of a secondary vortex cyclone filter device through a hose.

[0022] Since the wind force of the fan cannot be adjusted, the present application sets a damper at the air inlet end. When the damper at the air inlet end is adjusted larger, the wind force at the air suction end can be reduced, that is, the effect of regulating the wind force at the air suction end is achieved by controlling the air flow rate of the air inlet. The larger the air volume at the air inlet, the smaller the wind force at the air suction end.

[0023] Specifically, the air inlet and the air suction port are arranged at the bottom of the material screening chamber, the air inlet and the air suction port are arranged symmetrically, and the feed port forms a trumpet-shaped structure.
