Automatic cementing material density measurement and feeding system

Abstract

The invention relates to an automatic cementing material density measurement and feeding system. The system comprises a motor, a storage and feeding bin, a Lipsler bottle and a weighing device, wherein a motor fixing device is arranged on the motor, a spiral discharger and a poking blade are connected below the motor, a bin cover and a feeding pipe arranged on the bin cover are arranged on the storage feeding bin, the poking blade and the spiral discharger are arranged in the middle of the storage feeding bin, and the Lee bottle is fixedly connected with the weighing device through a Lee bottle fixing clamp. The system is advantaged in that a specific material storage and feeding bin is introduced to achieve a purpose that a sample cannot scatter out of a Lipsler bottle, a stepless speed change motor, a spiral discharger and a valve ensure that the feeding speed is controllable, stirring blades overcome the friction force and cohesion between the powder samples, so feeding continuity is ensured, the weighing device with a clamp ensures stability of the Lipsler bottle and accurate control of the feeding amount, and ensures accuracy of a measurement result, through introduction of anautomatic feeding system, parallel tests can be carried out synchronously, and detection efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of experimental auxiliary tools, in particular to an automatic gelling material density measurement feeding system. Background technique [0002] According to the relevant standards and regulations of the industry, at present, the density of gelling materials is mainly measured by using the Lee bottle according to the Archimedes principle. Determination process The test personnel manually put the sample into the Lees bottle with a small spoon, and calculate the sample density by dividing the mass of the sample in the Lees bottle by the volume of the liquid displaced by the sample. [0003] Manual feeding with a small spoon has the following problems: ①The sample is easy to scatter out of the Lishi bottle during the feeding process, resulting in a large test result; ②The manual feeding has a large human influence factor, and the feeding speed cannot be effectively controlled, which may easily lead to blockage of the bo...

Problems solved by technology

[0003] Manual feeding with a small spoon has the following problems: ①The sample is easy to scatter out of the Lishi bottle during the feeding process, resulting in a large test result; ②The manual feeding has a large human influence factor, and the feeding speed cannot be effectively controlled, which may easily lead to blockage of the bottleneck and lead to test failure. , increase the test time and affect the accuracy of the test results; ③Weigh the sample with a fixed mass first, and then add it to the Lee bottle, there may be some residues on the container and spoon, which will affect the accuracy of the test results; ④Parallel test It cannot be carried out simultaneously, and the efficiency is low; ⑤The deviation of the test results will lead to the development of other subsequent tests, such as the determination of the specific surface area, the accuracy of the mix ratio design, etc.
