Description

Sample collection and chemical sample collection and batch collection system

Technical Field

The invention mainly relates to the field of material sample collecting and preparing equipment, in particular to a sample collecting and preparing system.

Background

For sample collection and analysis of materials (such as ores and coals), the standards are mandatory in all countries, and the sample collection and analysis must be carried out according to the standards. Taking coal analysis as an example, the criteria of the sample collection and analysis working process is that the granularity of the collected sample is gradually reduced and the quality is gradually reduced on the premise of not damaging the representativeness of the sample until the granularity and quality (weight) precision requirements of laboratory tests on the sample are met, and then the relevant test analysis is carried out on the sample meeting the requirements. There can be no loss of sample in this process, and some physical or chemical changes in the sample can not occur, which would otherwise have an impact on the final test results.

Currently, the requirements on the sampling integrated operation and the sampling integrated system of the sample are higher and higher, such as sample matching and batch collecting operation. The collection and batching refers to that when the front end of sample collection and preparation operation is adopted, different coal samples in multiple batches are prepared and barreled together by samples, and each batch of coal sample barrels also has a certain number, and the coal samples are disordered in the preparation and transportation processes. This makes it necessary to collect and unify the different batches, different amounts, and disordered coal samples in the same batch first, and then to complete the sampling and preparation operation of each same batch in a centralized manner.

For example: part of the existing sample mixing and batching system is provided with a temporary storage transmission line, a sample preparation transmission line and a transfer transmission line which are in parallel; the part is provided with a temporary storage transmission line, a non-current sample transmission line, an empty barrel transmission line and a sample preparation transmission line which are in parallel; and the device is also provided with an empty barrel conveying belt, a sample preparation conveying belt and a batching circulation conveying belt which are longitudinally arranged in parallel. This has the following technical problems:

firstly, setting up so many transfer chain is bulky, and area is big, is unsuitable for industrialization nimble putting and use, especially if the operation of batch is put into to the fit appearance of many batches, in order to satisfy annular batch circulation and must make the system volume more huge and complicated. Secondly, every transmission line function is too single, and in the fit appearance of appearance bucket put into batches the in-process, the appearance bucket needs to circulate many rings on a plurality of conveying mechanism, and appearance bucket circulation transport takes longer time, and it is long to put into batches, and it is slow to put into batches rhythm, work efficiency is low. Thirdly, the number of card reading and writing times of the sample barrel is more, and sorting is difficult. After all sample storage barrels are read once, the sample barrels in the required batch can be selected, so that the reliability is reduced.

Also for example: and part of the existing sample collection and preparation combined sample batch system is provided with a barrel feeding conveying belt for being directly connected with a transfer trolley for conveying sample barrels, and all sample barrels on the transfer trolley are conveyed to the barrel feeding conveying belt and then conveyed to other conveying belt devices of the combined sample batch system through the barrel feeding conveying belt. When the empty barrel is discharged, the empty barrel is also conveyed into the transfer trolley through the barrel feeding conveying belt. This has the following technical problems:

Firstly, because the width of the transfer trolley is almost the same as that of the barrel feeding conveying belt, if the sample barrel is to smoothly enter and exit the barrel between the transfer trolley and the barrel feeding conveying belt, the trolley tail and the barrel feeding conveying belt are required to be aligned. The parking precision requirement on the transfer trolley is high, and if the parking is inaccurate, the transfer trolley needs to be backed up for multiple times to align. The vehicle has the advantages of high requirements on vehicle operators, difficult docking, long consumed time, low automation degree and low working efficiency.

Secondly, if the alignment is not aligned, the automatic in-out of the sample barrel is seriously influenced, so that the sorting and batch returning efficiency of the combined sample and batch returning is influenced, and the sample barrel is possibly dropped. And the alignment is not aligned, so that the position of the sample barrel transmitted to the barrel feeding transmission belt is not accurate, and the accurate butt joint of the barrel feeding transmission belt and other transmission belt devices of the sample batching system is affected.

Detailed Description

The invention is described in further detail below with reference to specific embodiments and figures.

As shown in fig. 1 to 10, the present invention provides a sample collecting and preparing system, comprising a control unit (not shown in the drawings), a front end docking and transporting unit 1, a rear end docking and transporting unit 2, and one or more batch-returning transporting units 3 disposed between the front end docking and transporting unit 1 and the rear end docking and transporting unit 2, wherein the front end docking and transporting unit 1 is used for docking with a transporting vehicle (a shown in the drawings), the rear end docking and transporting unit 2 is used for docking with a sample preparing device (C shown in the drawings), the batch-returning transporting unit 3 comprises a transporting frame 31, and the transporting frame 31 is provided with a plurality of leg assemblies (explicitly shown in the drawings but not numbered) for supporting. The transmission frame 31 is provided with a plurality of rollers 32 and a roller transmission line which is used for forming forward and reverse transmission so as to transmit the sample barrel 9; the transmission frame 31 is provided with a plurality of lifting limiting mechanisms 33 which can upwards extend from the gaps between the adjacent rollers 32, the lifting limiting mechanisms 33 are arranged in two parallel rows along the transmission direction and are used for sequentially dividing the roller transmission line into a first temporary storage sample transmission channel 311, a current sample transmission channel 312 and a second temporary storage sample transmission channel 313 from left to right when the roller transmission line is lifted, and the first temporary storage sample transmission channel 311 and the second temporary storage sample transmission channel 313 are used for temporarily storing a sample barrel 9 to be prepared which is transmitted by the front end butt joint transmission unit 1 or temporarily storing an empty sample barrel 9 after sample preparation which is transmitted by the rear end butt joint transmission unit 2; a plurality of double-sided bucket hooking mechanisms 34 are arranged on the transmission frame 31 along the transmission direction; in operation, under the control instruction of the control unit, the lifting limiting mechanisms 33 descend so that the double-side bucket hooking mechanism 34 hooks the same batch of sample buckets 9 on the first temporary storage sample transmission channel 311 or the second temporary storage sample transmission channel 313 onto the current sample transmission channel 312, and then the lifting limiting mechanisms 33 ascend so that the roller transmission line forward transmits the same batch of sample buckets 9 to be processed on the current sample transmission channel 312 to the rear end docking transmission unit 2 or reversely transmits the same batch of empty sample buckets 9 to the front end docking transmission unit 1.

The specific implementation principle is as follows:

it should be noted that, the following descriptions about the directions are described according to the directions shown in the drawings, so as to facilitate understanding, and are not limited to the technical solutions. In this embodiment, two sets of batching conveying units 3 arranged in parallel are arranged between the front end butt joint conveying unit 1 and the rear end butt joint conveying unit 2. Of course, in other embodiments, three sets, four sets or even more batching transport units 3 may be provided according to actual needs. Assuming that the cart is transporting E, F, G batches of buckets 9, the multiple buckets 9 of each batch are randomly and chaotic. After the trolley is well docked with the front-end docking and conveying unit 1, the lifting limiting mechanisms 33 are lifted, the roller conveying line is sequentially separated into a first temporary storage sample conveying channel 311, a current sample conveying channel 312 and a second temporary storage sample conveying channel 313 from left to right, and then the trolley conveys a plurality of sample barrels 9 which are placed in disorder to the first temporary storage sample conveying channel 311 and the second temporary storage sample conveying channel 313 through the front-end docking and conveying unit 1. During transmission, the plurality of lifting limiting mechanisms 33 are lifted to form isolation limiting, so that the sample barrels 9 on the first temporary storage sample transmission channel 311 and the second temporary storage sample transmission channel 313 can be normally conveyed in sequence.

In this embodiment, the front-end docking and transmitting unit 1 is provided with a code reading mechanism, and the code reading mechanism is in communication connection with the control unit of the present invention, and each time the trolley outputs one sample barrel 9, the information on the top cover of the sample barrel 9 is read (in the prior art), the sample barrel 9 is numbered, and the information is transmitted to the control unit. For example, the first output is designated as lot 1 barrel E and is located on the first staging channel 311 for the first one, the second output is designated as lot 1 barrel F, is located on the first staging channel 311 for the second one, and so on. In any case, the control unit can know which positions of the first buffered sample transfer channel 311 and the second buffered sample transfer channel 313 all the sample buckets 9 of any one lot are located. Of course, in other embodiments, the code reading mechanism may be directly disposed on the cart for reading, or directly disposed on the front end of the batching and conveying unit 3. This is not a limitation of the present application as long as the control unit can accept all data.

When all are transferred in place (state shown in fig. 1), the sample batching operation starts. The lifting limiting mechanisms 33 descend, and then the control unit issues control instructions to the double-side bucket hooking mechanism 34 to hook all the sample buckets 9 of the batch E on the first temporary storage sample transmission channel 311 and/or the second temporary storage sample transmission channel 313 onto the middle current sample transmission channel 312, so that sorting and sample collection of all the sample buckets 9 of the batch E are completed. Then, the lifting limiting mechanisms 33 are lifted to form limiting channels, and at this time, the roller transmission line forwards transfers the sample barrels 9 to be prepared in the same batch on the current sample transmission channel 312 to the rear end docking transmission unit 2, and the sample barrels are transmitted to sample preparation equipment for sample preparation through the rear end docking transmission unit 2. The batch-matching, batching and transmission of the batches F and G can be carried out subsequently. The first temporary storage sample transmission channel 311 and the second temporary storage sample transmission channel 313 can also be used for temporarily storing the empty sample barrel 9 after sample preparation, and after sample preparation is finished, the empty sample barrel 9 is transmitted in a reverse direction and is transmitted to the trolley through the front end butt joint transmission unit 1. In the above description, there are various ways to prevent the other batch sample barrels 9 on the first temporary sample transfer channel 311 and the second temporary sample transfer channel 313 from being transferred out when the roll transfer line transfers the E batch sample barrels 9 to be prepared on the current sample transfer channel 312 forward: first, the rollers 2 on the transport frame 1 are all independently operated, for example, when the rollers 32 of the front sample transport channel 312 are operated, the rollers 32 of the first temporary sample transport channel 311 and the second temporary sample transport channel 313 are not operated. Secondly, the rollers 32 of the first temporary storage sample transmission channel 311, the current sample transmission channel 312 and the second temporary storage sample transmission channel 313 are arranged in a common row, but as described below, a third blocking barrel mechanism 35 which can upwards extend from the gap between the adjacent rollers 2 is arranged at the transmission rear end of the first temporary storage sample transmission channel 311 and the second temporary storage sample transmission channel 313 on the transmission frame 31, and when the current sample transmission channel 312 is transmitted, the third blocking barrel mechanism 35 blocks the first sample barrel 9 on the first temporary storage sample transmission channel 311 and the second temporary storage sample transmission channel 313, so that the first sample barrel 9 and all subsequent sample barrels 9 can not go forward. In this process, the sample barrels 9 of the subsequent F lot and G lot may move to the conversion position (because the first temporary sample transmission channel 311 and the second temporary sample transmission channel 313 form a space after the sample barrels 9 of the E lot are hooked), but at this time, the control unit is controlled by the algorithm to recalculate the new positions of the sample barrels 9 of the F lot and G lot after the conversion position, and when the next F lot is combined, the precise hooking can be performed again on all the sample barrels 9 of the F lot after the conversion.

Through the special scientific design, the method has the following technical advantages:

the sample collecting and preparing combined sample batching system is compact and simple in structure, and the front end butt joint transmission unit 1, the rear end butt joint transmission unit 2 and the batching transmission unit 3 are used for effectively connecting a transmission vehicle with new materials of sample preparing equipment. And only one set of transmission line can complete collection before collection of sample barrels 9 to be prepared, collection and transportation of samples of different batches of sample barrels 9 and collection and transportation of empty sample barrels 9, and the device is small in size, small in occupied area and suitable for industrialized flexible placement and use.

The specific implementation principle is as follows:

The transverse translation mechanism 11 has a translation length that is far beyond the width of the cabin. The detection switch assembly 14 employs a laser detector or a position sensor, etc. When the delivery wagon is reversed, only need to be reversed in the length distance of the transverse translation mechanism 11, the longitudinal transmission mechanism 12 can translate on the transverse translation mechanism 11 at the moment, and after the detection switch assembly 14 on the longitudinal transmission mechanism 12 detects the carriage position of the delivery wagon, the longitudinal transmission mechanism can accurately stop translating and form accurate butt joint with the carriage. At this time, after the sample barrel 9 in the carriage is longitudinally transferred to the sample barrel positioning area, the longitudinal transfer mechanism 12 is horizontally translated to the position of the first temporary sample transfer channel 311 or the second temporary sample transfer channel 313, and then a plurality of sample barrels are longitudinally transferred to the first temporary sample transfer channel 311 or the second temporary sample transfer channel 313. And, owing to still be equipped with locating component 13 on the vertical transport mechanism 12, so can form a plurality of appearance bucket location areas on vertical transport mechanism 12, not only guaranteed in earlier stage that vertical transport mechanism 12 and carriage form accurate butt joint, guaranteed moreover that the appearance bucket can be accurate bear to vertical transport mechanism 12 when the vertical transport afterwards on to and on the accurate transmission to first temporary storage appearance transmission channel 311 or second temporary storage appearance transmission channel 313. Through the scientific design, the method has the following technical advantages:

Firstly, the horizontal translation mechanism 11 has certain translation length, and when the delivery wagon is reversed, the delivery wagon can be quickly and accurately abutted and delivered as long as the delivery wagon is reversed within the length distance of the horizontal translation mechanism 11 (but not necessarily to a certain point).
