For example: 1. in the preparation of samples for colloidal layer analysis, it is required that the sample particles are all less than 1.5mm (1.5mm sieve fraction 100%) while the sample below 0.2mm particle size does not exceed 30%. During sample preparation, the sample is firstly sieved by a 1.5mm sieve, then oversize products are crushed, and then sieved by the 1.5mm sieve, and the step of crushing and sieving the oversize products is repeated until all the oversize products are sieved. 2. In the preparation of the petrographic sample, the sample particles are required to be less than 1.0mm (1.0mm sieve fraction 100%) in total, while the sample below 0.1mm particle size does not exceed 10%. When the sample is prepared, the sample is firstly sieved by a 1.0mm sieve, then oversize materials are crushed, and then sieved by the 1.0mm sieve, and the oversize materials are crushed and sieved repeatedly until all the materials are sieved.
Therefore, there is a need to improve the prior art to overcome the deficiencies of the prior art.
The invention content is as follows:
the invention provides an automatic sieving and crushing device for preventing solid particles from being over-crushed in order to solve the problems in the prior art, and the automatic sieving and crushing device can effectively solve the over-crushing problem in sample preparation.
The technical scheme adopted by the invention is as follows: an automatic sieving and crushing device for preventing over-crushing of solid particles comprises: the double-roller crusher comprises an installation bottom plate, a motor support, a double-roller crusher motor, a transmission gear, a feeding hopper, a double-roller crusher, a double-roller feeding hopper, a rotary screen, a material collecting bin, a connecting sleeve, a rotary screen motor, a rotary screen support, a material discharging hopper, a rotary screen lifting plate and a machine body, wherein the motor support is arranged on the installation bottom plate, the double-roller crusher motor is arranged on the motor support, the double-roller crusher motor drives the double-roller crusher to rotate through the transmission gear, the feeding hopper is arranged on the machine body and positioned at one side of the movable double-roller crusher, the double-roller feeding hopper is positioned at the upper part of the double-roller crusher and fixed on a machine frame, the rotary screen is sleeved on the driving double-roller crusher, the rotary screen lifting plate is arranged on a rotary screen, the rotary screen is connected with the rotary screen motor through the connecting sleeve and driven by, the material collecting bin is fixed on the drum screen support, and a discharge hopper is arranged at the lower part of the material collecting bin.
Further, still include the cleaning tube, the cleaning tube is installed on the frame and is located the below of double-roll crusher.
The invention has the following beneficial effects:
(1) the double-roller crusher is externally provided with a drum screen, and the double-roller crusher is screened firstly and then crushed to effectively prevent over crushing;
(2) a rotary screen is arranged outside the double-roller crusher, so that the automation of the sieving and crushing process is realized;
(3) the configuration of cleaning tube inserts cleaning device, realizes cleaning to equipment, effectively prevents sample mutual contamination.
Description of the drawings:
fig. 1 is a schematic view of an automatic sieving and crushing device for preventing solid particles from being over-crushed according to the present invention.
The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
The automatic sieving and crushing device for preventing the over-crushing of the solid particles firstly sieves and then crushes a sample to be prepared, then sieves the sample after crushing, and repeatedly sieves and crushes the sample again until all the samples are sieved. It includes: mounting plate 1, motor support 2, double-roll crusher motor 3, drive gear 4, feeder hopper 5, double-roll crusher 6, double-roll feeder hopper 7, trommel 8, aggregate storehouse 9, adapter sleeve 10, trommel motor 11, trommel support 12, go out hopper 13, trommel lifting plate 14, organism 15 and cleaning tube 16, motor support 2 installs on mounting plate 1, double-roll crusher motor 3 installs on motor support 2, double-roll crusher motor 3 drives double-roll crusher 6 through drive gear 4 and rotates, feeder hopper 5 installs on organism 15, and is located the one side of moving double-roll crusher 6. The double roll feed hopper 7 is located at the upper part of the double roll crusher 6 and is fixed to the frame 15. The cleaning pipe 16 is installed on the frame 15 and located below the double-roller crusher 6, the rotary screen 8 is sleeved on the driving double-roller crusher 6, the rotary screen material lifting plate 14 is arranged on the rotary screen 8, the rotary screen 8 is connected with the rotary screen motor 11 through the connecting sleeve 10 and driven by the rotary screen motor 11, the rotary screen motor 11 is installed on the installation bottom plate 1 through the rotary screen support 12, the material collecting bin 9 is fixed on the rotary screen support 12, and the lower portion of the material collecting bin 9 is provided with the material discharging hopper 13.
