It has the advantages of compact structure, beautiful appearance, convenient use, stable operation, low noise, high working reliability, and convenient operation and maintenance, and is widely used in the fields of cement, chemical industry, etc.

[0003] At present, most of the domestic star-shaped dischargers have the following problems: the rotor shaft is located directly below the feed inlet, the falling material impacts the rotor shaft, the transmission load is large and the shaft is easy to break. When there are large pieces of material in the material, it is easy to get stuck in the gap between the star-shaped impeller and the shell, resulting in blockage. Summary of the Utility Model

[0004] The utility model provides a multifunctional star-shaped discharger, so as to solve the technical problems that the rotor shaft is easy to break and large pieces of material are easy to get stuck and blocked.

[0005] The utility model is realized by the following technical solutions:

[0006] A new type of star-shaped discharger, including a shell, the top of the shell is provided with a feed inlet, the bottom is provided with a discharge port, and a switch device capable of opening and closing is arranged at the side wall position of the discharge port;

[0007] The front and rear side walls of the shell are rotatably installed with rotor shafts, star-shaped impellers are fixed on the rotor shafts, the center line of the star-shaped impellers is located on the left side of the center line of the feed inlet, and a gap allowing part of the material to pass through is formed between the edge of the maximum outer diameter of the star-shaped impellers and the right side wall of the shell;

[0008] The top of the shell is rotatably connected with a flap that can be turned to the right, and the rotation axis of the flap is located directly above the center line of the star-shaped impeller.

[0009] Further, the front and rear side walls of the shell are provided with stop bars, and the stop bars are located on the left side of the flap and make the flap inclined to the right.

[0010] Further, the center line of the star-shaped impeller is located directly below the left edge of the feed inlet.

[0011] Further, the switch device is a gate valve.

[0012] Further, the left side, the top and the right side of the shell are respectively provided with a first inspection door, a second inspection door and a third inspection door.

[0013] Further, a weighing sensor is arranged at the bottom of the shell.

[0014] The beneficial effects achieved by the present utility model compared with the prior art are as follows:

[0015] 1. The center line of the star-shaped impeller is not on the same straight line as the center line of the feed inlet, reducing the impact of the falling material on the rotor shaft, reducing the risk of the rotor shaft being easily broken, and improving the service life;

[0016] A gap allowing some materials to pass through is formed between the edge of the maximum outer diameter of the star-shaped impeller and the right side wall of the housing, preventing large pieces of materials from clogging. The flap forms a seal with the top of the star-shaped impeller. When a large piece of material gets stuck between the flap and the star-shaped impeller, as the star-shaped impeller rotates, the flap flips to the right, causing the large piece of material to fall and get out of the stuck state, reducing the wear of the star-shaped impeller and protecting the rotor shaft;

[0017] 2. An insertion plate valve is installed at the discharge port. When the star-shaped discharger stops working, the insertion plate valve can be opened to lock the material and also play a role in locking air;

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] In the description of the utility model, it should be understood that the orientation or positional relationship indicated by the terms "front", "rear", "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. The present utility model will be further described below in conjunction with the drawings and embodiments.

[0024] As Figure 1-2 shown, this embodiment discloses a new type of star-shaped discharger, which mainly includes structures such as a housing 2, a star-shaped impeller 4, a flap 5 and a gate valve 6. An inlet 1 is machined at a position on the top right of the housing 2, and a discharge opening 8 is machined at the bottom of the housing 2. The gate valve 6 is installed at the side wall position of the discharge opening 8, so that the gate valve 6 becomes a switching device for controlling the opening and closing of the discharge opening 8.

[0025] A rotor shaft is rotatably installed on the front and rear side walls of the housing 2. The star-shaped impeller 4 is fixed on the rotor shaft. The center line of the star-shaped impeller 4 is directly below the left edge of the inlet 1, so that the center line of the star-shaped impeller 4 is located on the left side of the center line of the inlet 1. A gap allowing some materials to pass through is formed between the edge of the maximum outer diameter of the star-shaped impeller 4 and the right side wall of the housing 2.

[0026] A flap 5 is rotatably connected to the top of the housing 2 by a pin shaft, and stop bars 7 are installed on the front and rear side walls of the housing 2. The stop bars 7 are located on the left side of the flap 5 and make the flap 5 inclined to the right. Designed in this way, the flap 5 can be limited, so that the flap 5 can only flip to the right. The rotation axis of the flap 5 is directly above the center line of the star-shaped impeller 4. When the flap 5 is not actuated, there is a space of about 2 mm between the bottom edge of the flap 5 and the edge of the maximum outer diameter of the star-shaped impeller 4, avoiding collision between the star-shaped impeller 4 and the flap 5 during operation, and at the same time taking into account the sealing effect of the flap 5.

[0027] In order to facilitate the maintenance of the star-shaped impeller 4 and the flap 5, inspection doors 3 are provided on the left, top and right sides of the housing 2 respectively. In order to measure the material quantity, a weighing sensor is installed at the bottom of the housing 2.

[0028] The specific working process of the new type of star-shaped discharger described in this embodiment is as follows:

[0029] When the star-shaped discharger is not working, the discharge opening 8 is closed through the gate valve 6 to lock the material, and at the same time it also plays a role in locking air. When the star-shaped discharger is working, the star-shaped impeller 4 rotates clockwise, the material enters from the inlet 1, and then is discharged from the discharge opening 8 after passing through the star-shaped impeller 4. At this time, the flap 5 does not act, playing a role in guiding the material and also having a certain sealing effect to prevent the material from entering the left side of the star-shaped impeller 4. Since the center line of the star-shaped impeller 4 and the center line of the inlet 1 are not on the same straight line, the impact of the material falling on the rotor shaft is reduced, the risk of the rotor shaft being easily broken is lowered, and the service life is improved; a gap allowing some materials to pass through is formed between the edge of the maximum outer diameter of the star-shaped impeller 4 and the right side wall of the housing 2, which will not cause blockage of large pieces of materials. The flap 5 and the top of the star-shaped impeller 4 form a seal. When a large piece of material is stuck between the flap 5 and the star-shaped impeller 4, as the star-shaped impeller 4 rotates, the flap 5 flips to the right, so that the large piece of material falls and gets out of the stuck state, reducing the wear of the star-shaped impeller 4 and protecting the rotor shaft.
