Description

Cyclone Pulse Mill

technical field

The utility model relates to a cyclone pulse pulverizer.

Background technique

In the pharmaceutical pulverizer in the prior art, usually the material needs to be screened through the screen after being pulverized by the pulverizing blade in the pulverizing chamber. If the size of the material is too large, it will still remain in the pulverizing chamber to continue pulverizing, but the sieve is easy to grind during use. If the material is blocked, the material discharge will not be smooth. The existing method can only be carried out by manual maintenance. Since the crushing chamber is still full of materials, it is very easy to be polluted by external dust and bacteria after opening the material door.

Utility model content

The purpose of the utility model is to overcome the defects existing in the prior art, and provide a cyclone pulse pulverizer, which can prevent the clogging of the screen and improve the pulverization efficiency.

In order to achieve the above object, the technical solution of the utility model is to provide a cyclone pulse pulverizer, including a lower hopper, a crushing chamber connected with the lower hopper, a collecting box connected with the crushing chamber, and a The collection box is connected to the cyclone separator through the conveying pipeline, the material conveying pipe and the gas conveying pipe connected to the cyclone separator, the gas conveying pipe is connected to the dust removal box, and the dust removal box is provided with a pulse Dust collector, the dust removal box is connected with an exhaust duct, and the end of the exhaust duct is provided with an induced draft fan;

A crushing shaft is rotated in the crushing chamber, a crushing blade is fixedly arranged on the crushing shaft, and the crushing shaft is driven to rotate by a crushing motor. A reverse purge pipe is arranged on the outside of the screen, the reverse purge pipe faces the screen, and the reverse purge pipe is connected with a blower through a filter.

A further improvement is: a muffler is provided at the connection between the exhaust duct and the induced draft fan.

A further improvement is: a related fan is arranged on the material delivery pipe.

The advantages and beneficial effects of the utility model are: by setting the reverse purge pipe on the outside of the screen, by opening the blower, the purge air coming in and out of the blower is firstly filtered by the filter and then blown to the air by the reverse purge pipe. sieve, so as to facilitate the dredging of the sieve.

detailed description

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

As shown in Figure 1, a cyclone pulse pulverizer comprises a lower hopper 1, a crushing chamber 2 communicated with the lower hopper 1, a collecting box 8 communicated with the crushing chamber 2, and a The box 8 is connected to the cyclone separator 4 through the delivery pipeline, the material delivery pipe and the gas delivery pipe connected to the cyclone separator 4, and the gas delivery pipe is connected to the dust removal box 3, and the dust removal box 3 is provided with There is a pulse dust collector, the dust removal box 3 is connected with an exhaust duct, and the end of the exhaust duct is provided with an induced draft fan;

A crushing shaft is arranged to rotate in the crushing chamber 2, a crushing blade is fixedly arranged on the crushing shaft, and the crushing shaft is driven to rotate by a crushing motor, and a screen is arranged at the connection between the crushing chamber 2 and the conveying pipeline 5. A reverse purge pipe 6 is provided on the outside of the screen 5, the reverse purge pipe 6 faces the screen 5, and the reverse purge pipe 6 is connected to a blower through a filter.

By setting the reverse purge pipe 6 on the outside of the screen 5, by turning on the blower, the purge air coming in and out of the blower is first filtered by the filter and then blown to the screen 5 by the reverse purge pipe 6, thereby facilitating dredging Screen 5.

A preferred implementation manner in this embodiment is that a muffler is provided at the connection between the exhaust duct and the induced draft fan.

For the convenience of collecting materials, the preferred implementation mode in this embodiment is that the relevant fan 7 is arranged on the material conveying pipe.

The above is only the preferred embodiment of the utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made. And retouching should also be regarded as the protection scope of the present utility model.
