a first metering component 620, the first metering component 620 being disposed in the metering tank 610 for obtaining the weight of the light material in the metering tank 610;

a reaction tank 630, said reaction tank 630 being connected to a metering tank 610 to receive light materials within said metering tank 610; and

a second metering assembly 640, wherein the second metering assembly 640 is disposed on the reaction tank 630, and is used for obtaining the weight of the reaction tank 630;

wherein the second metering component 640 obtains the weight of the light material added into the reaction tank 630 according to the difference of the weights of the reaction tank 630 before and after the light material is added; and when the difference value between the weight of the light material added into the reaction tank 630 obtained by the second metering component 640 and the weight of the light material in the metering tank 610 obtained by the first metering component 620 is within a preset range, the light material is stopped from being conveyed to the reaction tank 630.

Thus, when the metering device 600 for light materials in the present disclosure is used, the weight of the light materials (such as diatomite) required is predetermined, and after the temperature is controlled to a predetermined temperature, the light materials are conveyed into the metering tank 610 for the first accurate metering; then the light materials which are accurately metered are conveyed to the reaction tank 630, the light materials added into the reaction tank 630 are accurately metered for the second time through the second metering component 640, and after all or most of the light materials are conveyed to the reaction tank 630, the light materials are stopped being added into the reaction tank 630, so that all or most of the light materials in the metering tank 610 and the temperature control device of the materials connected with the metering tank 610 can be ensured to be extracted, accurate feeding of the light materials is realized, and on the other hand, the light materials remaining in a conveying pipeline of the light materials are relatively less.

And the metering device 600 of the light material of the present disclosure also conforms to the record of the whole flow from the acceptance to the addition of the light material by the national drug administration.

Furthermore, when adding the light material to the feeding device of the light material, the initial metering, i.e. the single-shift addition of the light material, can be started.

In this disclosure, the metering device 600 for light materials further includes:

a material storage tank 650, the material storage tank 650 is formed with a feed inlet and a discharge outlet, wherein, the feed inlet of the material storage tank 650 is communicated with the metering tank 610, the discharge outlet of the material storage tank 650 is communicated with the reaction tank 630, and the material storage tank 650 is located above the reaction tank 630, so that when negative pressure is applied to the material storage tank 650, the light material in the metering tank 610 is conveyed to the material storage tank 650, and after the light material in the metering tank 610 is conveyed to the material storage tank 650, the negative pressure is stopped being applied to the material storage tank 650, the light material in the material storage tank 650 passes through the discharge outlet to enter the reaction tank 630, thereby realizing accurate feeding of the light material on the one hand, and on the other hand, remaining light material in the conveying pipeline of the light material is relatively less.

In an optional embodiment of the present disclosure, the material storage tank 650 is connected to an exhaust pipe 651, the exhaust pipe 651 is connected to a vacuum pipeline, and a filtering device 652 is disposed in the exhaust pipe 651, so that when the exhaust pipe 651 is connected to the vacuum pipeline, the interior of the material storage tank 650 can be in a negative pressure state, and thus the material in the metering tank 610 is pumped into the material storage tank 650.

Of course, the metering device 600 for the light materials may not include the storage tank 650, but the light materials are directly pumped to the reaction tank 630 through the negative pressure, as long as the operation can meet the process requirement in the reaction tank 630.

In an alternative embodiment of the present disclosure, the first metering assembly 620 includes at least one weighing module that obtains the weight of the light material within the metering tank 610 based on the difference in the weight of the metering tank 610 before and after the light material is added to the metering tank 610.

Preferably, the weighing module converts a pressure signal applied by the metering tank to the weighing module into an electrical signal, and different pressures have different electrical signals to obtain the weight of the metering tank through interpretation of the electrical signals.

In one implementation form, the weighing modules are mertler weighing modules, and when the number of the mertler weighing modules is two or more, the mertler weighing modules surround the metering tank 610 and are disposed outside the metering tank 610.

Similarly, the second metering assembly includes at least one weighing module disposed around the reaction tank 630 outside the reaction tank 630 when the number of the weighing modules is two or more.

In this disclosure, the light material loading ubiquitous gathers and/or the phenomenon of bridging, and technical means such as accessible are patted, vibrate solve, but this can influence the weighing accuracy of weighing device based on weight response. In a general application scenario, the error can be ignored, and the requirement for accurate symmetry is relatively low in fields such as energy exploitation and chemical smelting. The pharmaceutical industry has severe requirements on the error, for example, in the field of blood products, the dosage error of each kg of diatomite is only allowed to be 1-2g, so that a metering device with high accuracy needs to be selected.

Further, the high accuracy metering device is sensitive to system instability, which causes a problem of excessive weighing deviation. The inventor of the present disclosure finds that by providing a metering device on the reaction tank far from the vacuum generation system, the system error can be reduced to some extent, and the measurement deviation can be reduced. And when the difference value between the weight of the light material added into the reaction tank and obtained by the second metering component and the weight of the light material in the metering tank and obtained by the first metering component is within a preset range, the light material is stopped being conveyed to the reaction tank, and accurate feeding can be realized.

Therefore, the conveying pipeline 660 can realize simultaneous feeding of a plurality of reaction tanks 630 on one hand, and can realize the beneficial effect of less pipeline residue under the condition that the conveying path is increased and/or the total conveying amount is increased on the other hand.

Therefore, when the light materials are conveyed to the reaction tank 630 through the main pipeline 661 and the branch pipelines 662, the light materials existing in the branch pipelines 662 which do not convey the light materials fall back to the main pipeline 661 under the action of gravity, so that the light materials are conveyed to the other reaction tanks 630 during the operation, and particularly, when the light materials are conveyed to the reaction tank 630 connected to the main pipeline 661 only through the main pipeline 661, the light materials which fall back to the main pipeline 661 can be conveyed to the other reaction tanks 630.

Preferably, the angle between the flow direction of at least two of the light materials in the main pipe 661 and the flow direction of the light materials in the branch pipe 662 is the same.

Through tests, when the total conveying amount of the light material conveying pipeline of the disclosure is 100Kg or more, the pipeline residue can be controlled within 200g every time the light material is conveyed.

Particularly, the detection result of a single 400kg diatomite conveying system shows that the pipeline residue can be controlled within 20g when the light material is conveyed once; part of test results are within 40 g; the worst can be controlled within 160 g.

In an alternative embodiment of the present disclosure, the reaction tank 630 includes a stirring module, which is activated to stir the reactant in the reaction tank 630 when the material in the storage tank 650 enters the reaction tank 630.

In this disclosure, the light material gets into retort 630 through the bin outlet of holding material jar 650, slows down retort 630 atmospheric pressure fluctuation on the one hand, gets into retort 630 back jar internal gas pressure and plays the cushioning effect to the light material, and on the other hand has avoided the evacuation to retort 630 to extension retort 630 life has also practiced thrift the energy consumption.
