Description

Technical Field

[0001] The invention relates to a rotary reducing machine for sample preparation, in particular to a rotary reducing machine with temporary storage and automatic cleaning functions, belonging to the field of coal sampling and sample preparation. Background Art

[0002] In the field of ore sample preparation, sample preparation all adopts reduction devices. There are many types of reduction devices. Among them, the rotary reduction machine has a high usage rate because of the smallest qualitative error in the reduction process.

[0003] The general rotary shrinking machine has the following problems: first, because the robot arm is required to place the bottle directly on the rotating platform, there must be a gap between the upper port of the sample bottle and the outlet of the material guide tube. During the shrinking, dust will overflow from the gap; second, the material receiving barrel cannot be automatically moved in and out, and needs to be supported by the clamping frame on the barrel wall through the robot arm; third, the dust left on the tube wall during and after the material pouring process of the material guide tube is likely to cause environmental pollution.

[0004] Therefore, the applicant's new patent No. 2020216879984 discloses an automatic cleaning rotary reduction machine, which includes: a material holding mechanism, a uniform feeding mechanism, a rotatable material guide mechanism arranged below the uniform feeding mechanism, and several material guide tubes are evenly and continuously arranged along the circumference of the material guide mechanism; a disc-shaped bottle placing mechanism for placing sample bottles that can rotate with the material guide mechanism is arranged below the material guide mechanism, and a main power mechanism for driving the material guide mechanism and the bottle placing mechanism to rotate. It sends the sample to the material guide tubes evenly arranged on the rotating material guide mechanism through the feeding mechanism, and the sample is evenly divided and directly introduced into the sample bottle on the bottle placing mechanism through the material guide tube. The material guide tube cannot temporarily store the sample, but directly transports the sample to the sample bottle. Therefore, the sample bottle mechanism for placing the sample bottle must rotate synchronously with the material guide mechanism. It adds a dust suction mechanism, which is located on the side of the outlet of the material guide tube, for docking with the dust removal equipment, so as to realize the dust return and treatment of the material guide tube. It is further provided with a bottle in-and-out mechanism, which can transport the sample bottle from the bottle placement position of the robot to the bottle placement mechanism and is located below each material guide tube, and also has a lifting mechanism that drives the bottle placement mechanism to rise and fall, so that the opening of the sample bottle is just right. Therefore, the rotary dividing machine overcomes the above-mentioned problems in the prior art, by sending the sample bottle to the bottom of the material outlet of the material guide tube through the bottle in-and-out mechanism, and then docking the sample bottle with the material outlet through the lifting mechanism, avoiding the problem of dust caused by the gap between the two.

[0005] However, with the requirements for intelligent and automated fully automatic sample preparation equipment, it is found that the problems it has are: First, several material guide tubes correspond to several sample bottles, and they transport samples to the sample bottles while rotating. They cannot temporarily store samples and cannot unload samples at a fixed unloading position. In fully automatic combined sample preparation equipment, it is often necessary to further process and prepare the samples after reduction. If the samples are not unloaded at a fixed position, it is inconvenient for subsequent sampling. Second, a bottle placement mechanism that rotates simultaneously with the material guide mechanism is required to support the sample bottles, which makes its mechanism too complicated. Third, the material guide tube cannot be cleaned after reduction. After each reduction, when the next batch of materials is reduced, the residual materials from the previous reduction will cause cross-contamination to the next reduction, affecting the purity of the sample.

[0006] A rotary reducer with a fixed sample unloading position to facilitate subsequent sample preparation equipment to grab sample bottles at a fixed position, which can simplify the bottle placing mechanism of the sample bottles, omit the bottle placing mechanism driving mechanism, and clean the material guiding mechanism has become a goal pursued by technical personnel in this field.

In order to facilitate the sample bottle to be transferred to the bottle placing bracket, or taken away from the bottle placing bracket, and to make the sample bottle close to the outlet of the material guiding tube 53 during sample unloading, as a preferred embodiment, wherein the bottle placing and receiving mechanism 9 includes a bottle placing bracket 93 which can be raised and lowered and arranged below, a translation cylinder 91 is provided on the bottle placing bracket 93, and a bottle placing plate 92 for placing the sample bottle is arranged on the bottle placing bracket 93 through the translation cylinder 91; wherein the bottle placing bracket 93 includes a bottom plate 931 and a lifting plate 933 which is parallel to and horizontally arranged with the bottom plate 931, the lifting plate 933 is arranged by four guide pillars 932 and can slide along the guide pillars 932, and a sample bottle rack cylinder 97 for driving the lifting plate 933 to rise and fall is provided on the bottom plate 931.
