[0002] In the material sorting technical field, especially for the positive pressure specific gravity sorting process of large tonnage material, the performance and efficiency of the air supply system are directly related to the sorting effect and production efficiency. The traditional sorting equipment mostly adopts a multi-fan air supply system, which can meet the sorting requirements to some extent, but has problems such as high energy consumption, complex maintenance, and high equipment cost. Especially when processing large tonnage materials, the multi-fan system often has difficulty in ensuring the uniformity and stability of the air pressure, thereby affecting the accuracy and efficiency of sorting.

[0003] In addition, the traditional sorting equipment often uses direct blowing or suction of multiple fans in the air supply mode, which not only consumes a lot of energy, but also easily causes secondary pollution and damage to the material during the sorting process, reducing the sorting quality. At the same time, due to the non-uniformity of air pressure, it may also cause uneven distribution of materials on the sorting conveying surface, further affecting the sorting effect.

[0004] In order to solve the above problems, the industry has begun to explore more efficient, energy-saving and stable air supply systems. Among them, the single-fan air supply system gradually attracts attention due to its simple structure, low energy consumption, and convenient maintenance. However, the existing single-fan air supply system still has some deficiencies in design, such as single air inlet direction and uneven air pressure distribution, which limits its application in large and heavy material sorting.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] like Figures 1-4 As shown, a single-fan air supply system for a large-tonnage positive pressure gravity separator includes a frame 1, a sorting conveyor surface 2 installed on the frame 1, an inlet 3 and an outlet 4 installed on the frame corresponding to both ends of the sorting conveyor surface, a single-fan air supply assembly 5 installed on the frame corresponding to the lower position of the sorting conveyor surface, multiple air supply ports opened on the frame along the conveying direction of the sorting conveyor surface, the outlet position of the single-fan air supply assembly is connected to the air supply ports, and the single-fan air supply assembly includes a dual-inlet induced draft fan installed on the frame, the air inlet direction of the dual-inlet induced draft fan being perpendicular to the conveying direction of the sorting conveyor surface.

[0029] An air supply grille 7 is installed on the frame 1 at the position corresponding to the air supply port 6; this allows for more effective control of the airflow direction and speed. The air supply grille can evenly disperse the airflow, reduce airflow turbulence and eddies, and make the airflow act more smoothly on the material, thereby improving the accuracy and stability of sorting.

[0030] A baffle 8 is installed on the frame 1 between two adjacent air inlets, forming an air cavity between the baffle and the frame. Installing a baffle between two adjacent air inlets and forming an air cavity with the frame allows for further adjustment and optimization of the airflow distribution. The baffle guides the airflow within the air cavity, reducing direct impact and mutual interference, resulting in a more uniform airflow across the entire sorting and conveying surface, thus improving the consistency and accuracy of sorting.

[0031] The air adjusting assembly 9 is installed on the rack 1 corresponding to the air inlet position of the double air inlet induced draft fan, the air adjusting assembly 9 comprises an air adjusting plate 10 arranged at the air inlet position of the double air inlet induced draft fan, and a driving mechanism is installed on the rack for driving the air adjusting plate to slide along the conveying direction of the sorting conveying surface; the driving mechanism drives the air adjusting plate to slide, thereby adjusting the air inlet amount of the double air inlet induced draft fan; in addition, the air supply grille and the baffle can protect the air supply port from being directly impacted by materials and sundries, thereby reducing the wear and blockage risk of the air supply port. This helps to prolong the service life of the equipment and improve the stability and durability of the equipment; a support base is installed on the rack corresponding to the air supply assembly position of the single fan, a suspension plate 11 is installed on the rack corresponding to the top position of the air inlet of the double air inlet induced draft fan, the top of the air adjusting plate is clamped on the suspension plate, the driving mechanism comprises an adjusting rod 12 rotatably installed on the rack, an adjusting gear 13 is installed on the adjusting rod corresponding to the position of the air adjusting plate, and a driven rack part 14 cooperating with the adjusting gear is installed at the top of the air adjusting plate 10; the introduction of these components makes the position of the air adjusting plate flexible. By rotating the adjusting handle or starting the rotary driver, the adjusting rod 12 can be driven to rotate, and then the adjusting gear cooperates with the driven rack part to make the air adjusting plate move up and down. This design allows the user to accurately adjust the air inlet amount of the double air inlet induced draft fan according to the actual demand, thereby optimizing the sorting effect.

[0032] The adjusting rod extends through the rack and is coaxially installed with an adjusting handle or a rotary driver at one end; the adjusting handle is convenient for manual operation, and the rotary driver can realize automatic control, thereby improving the operation flexibility and intelligent level of the equipment.

[0033] A gap is reserved between the air adjusting plate and the air inlet of the double air inlet induced draft fan; this design helps to reduce the friction and collision between the air adjusting plate and the air inlet 15 of the double air inlet induced draft fan during movement, thereby reducing the wind resistance and noise. At the same time, the gap can also serve as an air flow buffer zone, making the air flow enter the double air inlet induced draft fan more smoothly and improving the utilization efficiency of wind energy.

[0034] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
