[0002] The air lock, also known as the air lock, air closure, star discharger, ash discharge valve, rotary feeder, etc., is a key equipment widely used in pneumatic conveying and ventilation dust removal systems;

[0003] Although the discharging effect can be achieved, there are still some problems in daily use. Since the discharging mechanism of the air lock is based on the operation of its internal rotating impeller, the materials in the interval space are discharged in piles during the rotation of the impeller. However, this discharging method is often difficult to achieve ideal uniformity. Secondly, the air lock faces the problem of easy agglomeration or arching between materials during the material feeding stage. After the material enters the air lock, due to the influence of physical properties, humidity, particle size and other factors, the particles may adhere and aggregate to form lumps that are difficult to flow or form material arch bridges. This phenomenon seriously hinders the normal flow process of the material in the air lock, which will cause intermittent discharge or even stop discharging when the air lock is discharging. Utility Model Content

[0020] like Figure 1-3 As shown, the anti-blocking component includes a mounting plate 500 which is laterally symmetrically arranged at the upper ends of the left and right surfaces of the outer shell 100, and the left and right ends of the upper surface of the outer shell 100 are provided with fixed cylinders 501 which are laterally symmetrically distributed, and the fixed cylinders 501 are vertically slidably connected with sliding cylinders 502, and a conical plate 503 is provided between the upper ends of the four sliding cylinders 502, and a spring 504 is provided between the top wall surface of the sliding cylinder 502 and the bottom wall surface of the vertically adjacent fixed cylinder 501; the anti-blocking component also includes a rotating rod 505 which is laterally rotatably connected to the middle part of the upper end of the inner cavity of the outer shell 100, and a cam 506 is provided in the middle part of the rotating rod 505, and the cam 506 is matched with the conical plate 503. The right extending end of the spiral blade 401 is also provided with a driving component for driving the rotating rod 505 and the rotating shaft 400 to rotate.

[0021] like Figure 1-4 As shown, the driving assembly includes a double-groove pulley 600 arranged at the right side extension end of the spiral blade 401, a single-groove pulley 1 601 is provided at the right side extension end of the rotating shaft 400, and the single-groove pulley 1 601 is connected to the left side ring groove of the double-groove pulley 600 through a belt 1 602 for transmission, and a single-groove pulley 2 603 is provided at the right side extension end of the rotating rod 505, and the single-groove pulley 2 603 is connected to the right side ring groove of the double-groove pulley 600 through a belt 2 604 for transmission.

[0022] The working principle of the air lock for uniform material discharge provided by the utility model is as follows: first, the relevant staff fixes the shell 100 and its auxiliary mechanisms in the preset material discharge area, and then, during material discharge, the relevant staff adjusts the operation of the motor 300 through an external single-chip microcomputer, and the rotation of the output shaft of the motor 300 drives the rotating impeller 200 and the double-groove pulley 600 to rotate synchronously, and the rotation of the rotating impeller 200 transfers the material from the upper feed port to the lower discharge port. In this process, the rotating impeller 200 plays the role of preventing blockage, locking air and unloading, and the double-groove pulley 600 drives the corresponding single-groove pulley 1 601 and single-groove pulley 2 603 to rotate synchronously through belt 1 602 and belt 2 604 when rotating, and the single-groove pulley 1 601 drives the rotating shaft 400 and the spiral blade 401 to rotate synchronously when rotating, and the two spiral blades 401 The spiral directions are opposite, so that the materials discharged from the space between the rotating impellers 200 can be dispersed, thereby achieving uniform discharge of the air lock. The single-groove pulley 603 drives the rotating rod 505 and the cam 506 to rotate synchronously when rotating. The cam 506 periodically contacts and pushes the conical plate 503. When the distal end of the cam 506 contacts the conical plate 503, the conical plate 503 overcomes the elastic force of the spring 504 and moves upward. When the distal end of the cam 506 separates from the conical plate 503, the conical plate 503 moves downward under the action of the rebound force of the spring 504, effectively preventing the problem of intermittent discharge or even stop of discharge caused by agglomeration and arching of materials during transportation, ensuring that the materials inside the air lock always maintain a good fluidity state, thereby achieving the continuity and uniformity of the discharge process of the air lock, and improving the overall discharge efficiency and stability of the air lock.

[0023] like Figure 1-2 As shown, symmetrically distributed mounting holes are provided at the four corners of the upper and lower surfaces of the housing 100, and the mounting holes facilitate relevant staff to fix the housing 100 and its auxiliary mechanisms in a designated discharge location.

[0024] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0025] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
