Description

Technical Field

[0001] This utility model relates to the field of grain machinery technology, specifically to a novel circulating air separator structure. Background Technology

[0002] The circulating air separator is mainly used to separate light impurities from raw grains, such as husks, shriveled grains, straw, mud, and dust. It plays a good role in ensuring the cleanliness of the workshop environment and improving the impurity removal effect of subsequent processes. It can be used alone in the raw grain cleaning process or in combination with other cleaning equipment (such as vibrating screens and threshing machines).

[0003] The circulating air separator can separate low-density impurities and light particles such as husks and dust from grains such as wheat, corn, barley and oilseeds. Under the action of the fan, airflow is generated, and the impurities are drawn into the air duct during the airflow process, thus separating them from the grain. The grain falls into the discharge port, while the impurities are carried away by the airflow and fall into the collection bin. The impurities are then discharged from the waste material outlet by the auger conveyor in the impurity removal mechanism.

[0004] However, existing circulating air separators cannot adjust the feed air velocity according to the type of feed, and the inventors have proposed an improvement to address this. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a novel circulating air separator structure with adjustable air intake speed that is adaptable to different bulk materials.

[0006] To achieve the above objectives, this utility model provides a novel circulating air separator structure, which adopts the following technical solution:

[0007] A novel circulating air separator structure includes:

[0008] The housing has an inlet on one side and an outlet on the other side.

[0009] An air duct assembly is encapsulated inside a housing, wherein the air duct assembly is connected to the feed inlet;

[0010] A debris removal mechanism is provided on one side of the air duct assembly. The debris removal mechanism includes a closed air baffle, and a cylindrical separator is encapsulated inside the closed air baffle.

[0011] The dust collection mechanism is located below the impurity removal mechanism; and

[0012] The duct adjustment block is installed on the duct assembly and is detachable from the duct assembly. By setting the duct adjustment block, the thickness of the duct can be adjusted to control the air velocity within the suction duct.

[0013] A further improvement of this novel circulating air separator structure lies in that the air duct assembly includes a vertical air duct and an adjusting air plate connected to the vertical air duct. The adjusting air plate is provided with a horizontal dovetail groove, within which a detachable air duct adjusting block is installed. The design of the air plate and the dovetail groove emphasizes the flexibility of the detachable air duct adjusting block, enabling adjustment of the air duct thickness to accommodate different materials.

[0014] A further improvement of the novel circulating air separator structure of this utility model is that the lower half of the cylindrical separator is a grid-shaped air guide plate, and one end of the cylindrical separator is connected to the air inlet of the centrifugal fan.

[0015] A further improvement of the novel circulating air separator structure of this utility model is that the integrated device includes an auger, and a debris outlet communicating with the outside is provided on one side of the auger.

[0016] A further improvement of this novel circulating air separator structure is that an observation window is provided on the housing.

[0017] A further improvement of this novel circulating air separator structure is that an openable and closable valve is provided at the impurity outlet.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By setting up duct adjustment blocks, the thickness of the duct can be adjusted to control the air velocity inside the suction duct.

[0020] 2. The design of the air vane and dovetail groove highlights the flexibility of the detachable air duct adjustment block, which can adjust the air duct thickness to adapt to different materials. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-3 As shown, a novel circulating air separator structure includes:

[0027] The box body 100 has a feed inlet 110 on one side and a discharge outlet 120 on the other side.

[0028] An air duct assembly 210 is encapsulated inside a housing, wherein the air duct assembly is connected to the feed inlet;

[0029] A debris removal mechanism 200 is provided on one side of the air duct assembly. The debris removal mechanism includes a closed air baffle 230, and a cylindrical separator 240 is encapsulated inside the closed air baffle.

[0030] The dust collection mechanism 300 is installed below the impurity removal mechanism; and

[0031] The air duct adjustment block is installed on the air duct assembly and is detachable from the air duct assembly. By setting the air duct adjustment block 220, the thickness of the air duct can be adjusted to control the air velocity inside the air intake duct.

[0032] Specifically, the air duct assembly includes a vertical air duct and an adjustable air plate connecting to the vertical air duct. The adjustable air plate is provided with a horizontal dovetail groove, within which a detachable air duct adjustment block is installed. The design of the air plate and the dovetail groove highlights the flexibility of the detachable air duct adjustment block, enabling adjustment of the air duct thickness to accommodate different materials.

[0033] Specifically, the lower half of the cylindrical separator is a grid-shaped air guide plate, and one end of the cylindrical separator is connected to the air inlet of the centrifugal fan 250.

[0034] Specifically, the integrated device includes an auger 311, with a waste material outlet 312 connected to the outside on one side of the auger.

[0035] Specifically, the enclosure is equipped with an observation window.

[0036] Specifically, a valve that can be opened and closed is installed at the waste material outlet.

[0037] The working principle of this utility model:

[0038] Material enters the housing through the feed inlet. An adjustable baffle is installed in the vertical air duct. By adjusting and replacing different air duct adjustment blocks, the thickness of the air duct components can be controlled to regulate the airflow velocity within the suction duct. The impurity removal mechanism includes a cylindrical separator and a closed baffle. The lower half of the cylindrical separator is a grid-shaped air guide plate. One end of the cylindrical separator is connected to the air inlet of the centrifugal fan. Air purified by the separator enters the cylindrical separator through the air guide grid and is drawn away by the fan. The relatively dense clean material falls vertically and is discharged from the machine through the outlet. Under the action of the vertical airflow in the air duct, light impurities are carried to the dust collection mechanism. These light impurities are then sent to the waste material outlet by a spiral auger and discharged from the machine.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
