Description

Technical Field

[0001] The utility model relates to the technical field of separators, in particular to a separator for an air flow pulverizer. Background Art

[0002] The main features of the cyclone separator are simple structure, great operational flexibility and high efficiency. It is a dry gas-solid separation device that uses the centrifugal force generated by the high-speed rotation of the gas-solid mixture to separate dust from the airflow. The cyclone separator used in the crusher is smaller in size than the traditional cyclone separator and is more convenient to use.

[0003] Traditional cyclone separators collect dust particles in the airflow through the ash hopper installed at the bottom during use. However, the ash hopper of most cyclone separators is currently installed by bolt connection, which leads to several problems. First, this connection method makes the disassembly and assembly of the ash hopper quite cumbersome, requiring users to spend a lot of time and energy. Secondly, due to the large number of bolts, it is easy for the bolts to loosen or fall off, resulting in problems with the sealing between the ash hopper and the separator, which in turn affects the normal operation of the separator.

[0004] Therefore, it is necessary to provide a separator for a jet mill to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a separator for a jet mill to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0011] Preferably, an annular sealing plate is fixedly mounted on the top of the ash hopper, and a sealing gasket is bonded to the inner surface of the annular sealing plate and the inner wall of the connecting port.

[0012] Preferably, the limiting mechanism includes two limiting grooves, and the two limiting grooves are symmetrically distributed and opened on the rear side of the back side of the fixed box. The back sides of the two movable plates are fixedly installed with limiting blocks, and the limiting blocks are slidably connected to the corresponding limiting grooves.

[0013] Preferably, a threaded hole matched with the adjusting screw rod is opened at the rear of one side of the movable plate, and the movable plate is threadedly connected to the adjusting screw rod through the threaded hole at the rear of one side of the movable plate.

A symmetrically distributed movable plate 10 is sleeved on the outer wall of the adjusting screw rod 13. A limiting mechanism is arranged at the rear side of the interior of the fixed box 3.

[0032] A limiting hole 17 is provided on the upper side of the outer wall of the positioning rod 6, and a limiting rod 9 corresponding to the position and number of the limiting hole 17 is fixedly installed on one side of the movable plate 10 close to the positioning rod 6, and the limiting rod 9 is plugged into the limiting hole 17, and a driving mechanism is provided on the rear side of the top of the inner wall of the fixed box 3.

[0033] An annular sealing plate 8 is fixedly mounted on the top of the ash hopper 5 , and sealing gaskets are bonded to the inner surface of the annular sealing plate 8 and the inner wall of the connecting port 7 .

[0034] In one embodiment, the limiting mechanism includes a limiting groove 12, and the number of the limiting grooves 12 is two, the two limiting grooves 12 are symmetrically distributed and opened on the rear side of the back side of the fixed box 3, and the backs of the two movable plates 10 are fixedly installed with limiting blocks 11, and the limiting blocks 11 are slidably connected to the corresponding limiting grooves 12 to ensure stable lateral movement of the two movable plates 10.

[0035] In one preferred embodiment, a threaded hole matched with the adjusting screw rod 13 is opened at the rear of one side of the movable plate 10, and the movable plate 10 is threadedly connected to the adjusting screw rod 13 through the threaded hole at the rear of one side of the movable plate 10.

[0036] In one embodiment, the driving mechanism includes a motor 14, and the motor 14 is fixedly installed on the rear side of the top of the inner wall of the fixed box 3, and a second gear 16 is fixedly installed on the driving end of the motor 14.

[0037] In one of the preferred embodiments, the inner surface of the annular sealing plate 8 is inclined, and the inclination angle of the inner surface of the annular sealing plate 8 is adapted to the inclination angle of the outer wall of the conical cylinder 2, ensuring a perfect fit between the annular sealing plate 8 and the conical cylinder 2.

[0038] The working principle of the utility model is as follows: the electrical components appearing in the present application are all externally connected to the power supply and the control switch when in use. During the use of the separator, for the installation of the ash hopper 5, the bottom end of the conical cylinder 2 is directly inserted into the interior of the connection port 7 at the top of the ash hopper 5, and at the same time, the positioning rods 6 on both sides of the top of the ash hopper 5 are inserted into the interior of the fixed box 3 through the jacks 18 at the bottom of the positioning plate 4, so that the inner wall of the connection port 7 is tightly against the outer wall of the bottom end of the conical cylinder 2, and then the motor 14 is controlled by the switch to start working, and the driving end of the motor 14 drives the second gear 16 to rotate, and the first gear 15 is engaged with the second gear 16, so that the first gear 15 drives the adjusting screw rod 13 to rotate, and the thread transmission of the left-handed thread and the right-handed thread on the adjusting screw rod 13, and the sliding relationship between the movable plate 10 and the limiting block 11 and the limiting groove 12, so that The two movable plates 10 can move relative to each other or oppositely at the same time. The movement of the movable plates 10 drives the limit rod 9 to move. When the two sets of movable plates 10 move relative to each other, the limit rod 9 will be directly inserted into the upper limit hole 17 of the positioning rod 6, and the positioning rod 6 will be firmly limited inside the fixed box 3, and the ash hopper 5 will be firmly fixed at the bottom end of the conical cylinder 2. When the ash hopper 5 needs to be disassembled and cleaned later, the two movable plates 10 will move oppositely, and the limit rod 9 will lose the limiting effect on the positioning rod 6. At this time, the ash hopper 5 can be directly removed from the bottom end of the conical cylinder 2. For the fixing method of the ash hopper 5, the position of the ash hopper 5 is fixed by plugging and then by a mechanically driven positioning mechanism. First, through the plug-in design, the operation process is more concise and clear, which greatly reduces the time and energy cost of users during installation and disassembly. Secondly, with the mechanically driven positioning structure, the stable connection between the ash hopper 5 and the conical cylinder 2 is ensured, and the operation failure and safety hazard caused by loose connection or falling off are effectively avoided.

[0039] When the bottom end of the conical cylinder 2 is inserted into the connection port 7 and connected to the ash hopper 5, the inner surface of the annular sealing plate 8 will be in close contact with the outer wall of the conical cylinder 2, which not only increases the contact area between the ash hopper 5 and the conical cylinder 2, thereby making the connection more firm and stable, but also further improves the sealing effect of the connection by setting the sealing gasket on the annular sealing plate 8. This sealing design effectively prevents the problem of dust leakage in the airflow and ensures the efficient operation of the cyclone separator.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.

Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
