Abstract
The utility model relates to an automatic tester for the melting point of paraffin, which belongs to a testing device for the melting point of paraffin in the petrochemical field. Due to the adoption of an advanced temperature sensor and computer control technique, the utility model overcomes the influence on a test result by all human factors, simultaneously enhances test precision and repetitiveness of test data, realizes full automation, automatic timing and real-time printing in the testing process, and raises work efficiency in the testing process of the melting point of paraffin.
Description
The utility model belongs to a kind of paraffin melting point (cooling curve) automatic assay device in the petrochemical industry.
Paraffin is a kind of petrochemicals, and the difference of paraffin melting point shows the difference of paraffin quality.Therefore, to the mensuration of paraffin melting point,, vital role is arranged all to the application of paraffin in the development of the national economy.
Before the utility model, China is aspect the paraffin melting point test, it all is regulation by GB GB2539-81, the paraffin melting point analyzers that great majority all adopt Fushun Petrochemical Research Institute to produce, this instrument are as shown in Figure 1: be made up of test tube (1), cork (2), (3), (4), tubular air bath (8), round cup shaped water-bath ware (5), fusing point water bath thermometer (6) and water bath thermometer (7).
This instrument test process all is manually-operated.Observe reading of data on one side, one side record, time one is long, eyes produce tired, easily produce reading error, and inefficiency, in order to overcome above-mentioned shortcoming, the purpose of this utility model is to adopt advanced temperature sensor and is equipped with intelligentized computer software and hardware system, and it is full-automatic that test is realized, to increase work efficiency and measuring accuracy and good repeatability thereof.
Detailed content of the present utility model is as shown in Figure 2: be made up of test tube (12), soft plug (11), (13), (14), tubular air bath (16), round cup shaped sealing water-bath ware (10), temperature sensor (15), water bath thermometer (9), controlling of sampling case (17).Controlling of sampling case (17) is provided with that computing machine is soft, hardware, mini-printer, acoustooptic alarm system.
The diameter of test tube (12) is less than the diameter of tubular air bath (16), and test tube (12) places tubular air bath (16) lining, is positioned at axis that the center makes both on same straight line; The outside of tubular air bath (16) is a round cup shaped sealing water-bath ware (10), the inner ring wall of the outer wall of tubular air bath (16) and round cup shaped sealing water-bath ware (10) is an one, and the end face of the plane at tubular air bath (16) opening place and round cup shaped sealing water-bath ware (10) at grade; The center pit of soft plug (13) and temperature sensor (15) match, and temperature sensor (15) is connected with lead with controlling of sampling case (17); The interior garden of the outer garden of soft plug (13) and test tube (12) matches, and the center pit of the outer garden of test tube (12) and cork (14) matches, and they are fixed in the tubular air bath (16) together; The center pit of soft plug (11) and water bath thermometer (9) match, and they are fixed on the opening of end face of round cup shaped sealing water-bath ware (10) together.
The principle of work of this instrument explanation: fill specified altitude, temperature in the round cup shaped sealing water-bath ware (10) at 16 ℃～28 ℃ water, tested liquid wax sample is housed in the test tube (12), make liquid wax sample submergence temperature sensor (15), the test tube (12) that will fill liquid wax sample and temperature sensor (15) is put into tubular air bath (16) along axis.Like this, in liquid wax sample cooling procedure, write down one time temperature per 15 seconds, total poor when being no more than 0.1 ℃ when what five continuous-readings for the first time occur, be the deadtime first time, the mean value of five continuous-readings is the wax sample fusing point of being tested.
Good effect of the present utility model: this instrument adopts advanced temperature sensor and computer control, improved work efficiency widely, alleviated labour intensity, when overcoming all artificial factor affecting test results, improved the repeatability of measuring accuracy and test data widely, realized full-automatic process, self-timing, real time print to the paraffin melting point test.
Description of drawings: Fig. 1 is the structural representation of prior art; Fig. 2 is a structural representation of the present utility model, and Figure of abstract also adopts Fig. 2.
Most preferred embodiment: the material of test tube (12), tubular air bath (16) and round cup shaped sealing water-bath ware (10) adopts glass, the outer wall of test tube (12) to distance between the inwall of tubular air bath (16) keeps 13mm, fill the tap water that temperature is controlled at 16 ℃～28 ℃ in the round cup shaped sealing water-bath ware (10), temperature sensor (15) adopts Pt100, and the computing machine on the controlling of sampling case (17) adopts single-chip microcomputer.
