[0002] Flour is a powdery substance made from milled wheat. Based on its protein content, flour can be categorized into high-gluten flour, medium-gluten flour, low-gluten flour, and gluten-free flour. The flour processing process generates a large amount of dust, which not only pollutes the environment and harms worker health but also poses an explosion risk. Therefore, installing efficient dust recovery devices is crucial.

[0003] The dust recovery device includes a housing, a dust collection component, and filter bags. The dust collection component draws dust into the housing, where it is then filtered through the filter bags. After a period of use, the filter bags need to be disassembled, cleaned, or replaced.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] As shown in the figures, a dust recovery device for flour processing includes a support frame, a housing, a lid, and filter bags. The housing is fixedly mounted on the top of the support frame. The lid is slidably installed on the housing. A handle is fixedly provided on one side of the lid. Multiple sets of filter bags are inserted into the surface of the lid, and the sets of filter bags are staggered. A dust collection hopper is fixedly provided at the bottom of the housing, and a discharge pipe is fixedly provided at the bottom of the collection hopper. A control valve is provided on the discharge pipe. The surface of the housing is provided with a feature for controlling the dust flow. The dust collection assembly, as shown in Figures 1 and 2, specifically includes a tube and a cover. The tube is fixedly inserted into one side surface of the housing, and the cover is fixedly installed on the other side surface of the housing. An air collection hood is fixedly installed at the other end of the tube. A suction fan is fixedly installed on the surface of the cover. A slot is opened at the top of the cover. A sealing plate is fixedly installed on one side surface of the housing cover, and the sealing plate is adapted to the slot. A sealing strip is fixedly installed on the side of the sealing plate. One end of each of the multiple filter bags extends to one side of the housing cover.

[0025] More specifically, when the suction fan is started, it draws in air from outside the chamber. Dust follows the air through the air collection hood and pipe into the interior of the chamber, where it is filtered by multiple sets of filter bags. The filtered air is then discharged to the outside of the chamber. When the suction fan stops operating, the dust on the surface of the multiple sets of filter bags falls into the collection hopper. When the chamber cover is slidably installed with the chamber body, the cover moves vertically downwards, and one end of the multiple sets of filter bags passes through the inner wall of the slot until it is blocked by the cover. After the chamber cover is installed, the sealing plate seals the slot, thus preventing gas from flowing out.

[0026] The surfaces of the box body and the box cover are provided with connecting mechanisms for fixing the box cover to the box body, as shown in Figures 1 and 2. Specifically, the connecting mechanism includes a guide rail. The guide rail is fixedly provided on the surface of the box body. A slider is slidably installed inside the guide rail. A return spring is fixedly provided on one side of the slider and on the opposite side of the inner wall of one side of the guide rail. An auxiliary rod is fixedly provided at the top of the slider. A vertical plate is fixedly provided on the surface of the box cover. A rectangular groove is opened on the surface of the vertical plate. There are two sets of the guide rail, slider, return spring, vertical plate, and rectangular groove. The auxiliary rod is U-shaped, and its two ends are respectively adapted to the two sets of rectangular grooves. The box cover is L-shaped. The opposite sides of the two sets of vertical plates are respectively attached to the two side surfaces of the box body. There is a gap between the auxiliary rod and the box body.

[0027] More specifically, pulling the auxiliary rod causes the slider to slide, compressing the return spring as it slides. When the lid and body are slidably installed, the auxiliary rod is released. At this point, the return spring causes the slider to return to its original position, allowing one end of the auxiliary rod to insert into the rectangular slot, thus fixing the vertical plate and subsequently the lid. Pulling the auxiliary rod causes both sets of sliders to slide simultaneously. After the lid and body are installed, releasing the auxiliary rod causes both ends of the auxiliary rod to insert into the two rectangular slots, locking both sides of the lid. The auxiliary rod does not interfere with the body during its movement. After the lid and body are installed, the opposing surfaces of the two sets of vertical plates can contact the two side surfaces of the body, thus improving the stability of the lid.

[0028] In summary: Multiple filter bags are inserted into the cover, which is then slidably installed onto the housing. A connecting mechanism secures the cover to the housing, allowing for easy assembly and disassembly. When the dust collection unit is activated, dust is drawn into the housing and filtered through the multiple filter bags. Because the filter bags are staggered, dust on their surfaces falls into the collection hopper, which collects the dust. The inverted pyramid-shaped collection hopper allows for maximum dust discharge when the control valve is opened. This device facilitates easy assembly and disassembly of the filter bags, making cleaning and replacement convenient. Furthermore, it allows for easy dust discharge from the collection hopper, improving work efficiency and reducing labor intensity.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
