The utility model discloses a grinding type pulverizer, including grinder 2, drive arrangement 1 and screen assembly 3.
The grinding device 2 is used for grinding the sample to enable the sample particles to meet the sieving requirement. The grinding device 2 is provided with a feed inlet 206 and a discharge outlet 207, a sample enters the grinding device 2 through the feed inlet 206, and the ground sample is taken out through the discharge outlet 207.
The driving device 1 provides power for the grinding work of the grinding device 2, and the driving device 1 drives the grinding device 2 to vibrate, so that the sample is ground.
The discharge port 207 of the grinding device 2 is communicated with the screen assembly 3.
The abrasive pulverizer that this scheme provided has increased screen cloth subassembly 3, and is concrete, screen cloth subassembly 3 include with the base 301 of discharge gate 207 intercommunication, with base 301 complex upper cover 303 with set up the screen cloth 302 between base 301 and upper cover 303, upper cover 303 inhales material device 4 intercommunication through pipeline and vacuum, base 301 and upper cover 303 constitute the cavity that holds the sample, screen cloth 302 separates the cavity.
Vacuum suction device 4 carries out the evacuation operation to the cavity, and the cavity forms the negative pressure, absorbs the sample in grinding device 2, and the sample at first gets into base 301, then through screen cloth 302, and the sample that accords with the requirement of sieving passes through screen cloth 302 and gets into upper cover 303, is taken away by vacuum suction device 4, and the sample that does not accord with the requirement of sieving stays base 301, sends into grinder 2 once more and grinds the rethread screen cloth 302 and is taken away by vacuum suction device 4 after satisfying the requirement of sieving. The abrasive type rubbing crusher that this scheme provided can make the sample 100% that gets into vacuum and inhale material device 4 satisfy the requirement of sieving, has effectively improved the rate of sieving of sample.
Inhale material device 4 through the vacuum and extract the sample of screen cloth subassembly 3, need not open and grind lid 201 and can take out the sample, realized taking out fast of sample, shortened the time of taking out of sample, reduced the artifical intensity of labour that the sample was taken out, improved operational environment.
In order to further optimize the technical scheme, the upper cover 303 of the grinding type pulverizer provided by the scheme is provided with an anti-blocking device 304 for preventing the screen mesh 302 from being blocked by the sample. Prevent stifled device 304 and clear up the sample on the screen cloth 302, guarantee that screen cloth 302 is not blockked up by the sample, guarantee abrasive type rubbing crusher's continuation work, in addition, do not need the staff to dismantle screen assembly 3 just can realize the clearance to screen assembly 3, reduced the abluent artifical intensity of labour of screen assembly 3.
In a specific embodiment of the present disclosure, the anti-blocking device 304 is an air nozzle, the air nozzle is communicated with the air supply device, and the air nozzle blows air to clean the sample on the screen 302, preferably, the number of the air nozzles is two, and the two air nozzles are oppositely arranged and symmetrically distributed on two sides of the pipeline connecting the upper cover 303 and the vacuum suction device 4.
In another embodiment of the present disclosure, the anti-blocking device 304 is a vibrator, and the vibrator drives the screen assembly 3 to vibrate, so that the attached sample on the screen 302 falls off. Specifically, the vibrator is a pneumatic vibrator or an electric vibrator.
In order to further optimize the technical scheme, the base 301 of the screen assembly 3 provided by the scheme is a funnel-shaped base 301, the upper cover 303 is a funnel-shaped upper cover 303, and the base 301 is in bolted connection with the upper cover 303. The base 301 is designed as a funnel-shaped base 301, and when the sample cannot pass through the screen 302 due to the excessively large particle size of the sample, the sample can automatically fall back to the grinding apparatus 2 along the inclined wall of the base 301, reducing the amount of the sample attached to the base 301. The upper cover 303 is designed to be a funnel-shaped structure, and the wind power at the upper end of the upper cover 303 is larger than that at the lower end of the upper cover 303, so that the sample can be quickly taken away, and the energy loss is reduced.
The base 301 and the upper cover 303 are connected through bolts, so that the assembly difficulty of the screen assembly 3 is reduced.
Preferably, all set up on base 301 and the upper cover 303 with screen cloth 302 complex mounting groove, the mounting groove has played limiting displacement to screen cloth 302, can guarantee the sealed between base 301 and the upper cover 303 simultaneously.
Preferably, the base 301 and the cover 303 are made of metal material, and the screen 302 is also made of metal screen.
In one particular embodiment of the present solution, the grinding device 2 comprises a grinding bowl 202, a grinding ring 203, a grinding rod 204 and a grinding cover 201.
The grinding bowl 202 is a cavity with an open end at the upper end, and the cavity is used for containing materials. Specifically, the grinding bowl 202 is a cone structure with a large upper end and a small lower end, and the grinding bowl 202 needs to have high use strength to avoid the influence on the service life of the grinding bowl 202 caused by the repeated impact of the grinding ring 203 and the grinding rod 204.
The grinding ring 203 is matched with the shape of the inner wall of the cavity of the grinding bowl 202, and the diameter of the periphery of the grinding ring 203 is smaller than that of the inner wall of the grinding bowl 202, so that the grinding ring 203 can move in the cavity of the grinding bowl 202.
The polishing rod 204 is disposed in the cavity and located inside the ring of the polishing ring 203, and the polishing rod 204 and the polishing ring 203 repeatedly impact during polishing to polish the sample. The greater the driving force of the driving device 1, the greater the impact force between the grinding rod 204 and the grinding ring 203, the smaller the driving force of the driving device 1, and the smaller the impact force between the grinding rod 204 and the grinding ring 203.
In order to prevent the sample from overflowing from the open end of the grinding bowl 202, a grinding cover 201 is arranged on the upper end face of the grinding bowl 202, a feed inlet 206 and a discharge outlet 207 are arranged on the grinding cover 201, and the feed inlet 206 and the discharge outlet 207 are communicated with the space between the grinding ring 203 and the grinding rod 204.
