Background

According to the relevant standards and regulations of the industry, the density of the gelled material is currently determined mainly according to the Archimedes principle by using a Lee's bottle. Measurement Process test A tester manually loads a sample into a Li's flask a little by a little with a small spoon, and calculates the density of the sample by dividing the mass of the sample loaded into the Li's flask by the volume of the liquid from which the sample is discharged.

The manual spoon feeding has the following problems: firstly, the sample is easy to scatter outside the Lee's bottle in the feeding process, so that the test result is larger; manual feeding has large artificial influence factors, the feeding speed cannot be effectively controlled, bottleneck is easily blocked, test failure is easily caused, the test time is increased, and the accuracy of a measurement result is influenced; thirdly, a sample with fixed mass is weighed and then added into the Li's bottle, and partial residues possibly exist on the material container and the small spoon, so that the accuracy of a test result is influenced; parallel tests cannot be synchronously carried out, and the efficiency is low; fifthly, the deviation of the test result can cause the development of other subsequent tests, such as the measurement of specific surface area, the accuracy of the design of mixing ratio and the like.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: there are many influencing factors in manual feeding survey gelled material density, in order to overcome the not enough that exists in the prior art, provide a feeding system is surveyed to automatic gelled material density.

The technical scheme adopted by the invention is as follows: the utility model provides an automatic change cementitious material density survey feeding system, includes motor, storage and adds feed bin, Li shi bottle and weighing device, the motor on dispose the motor fixing device that can adjust from top to bottom, the motor below is connected with the spiral and expects glassware and fixed connection in the stirring blade of spiral under glassware, the storage add the feed bin on be equipped with the cang gai and locate the filling tube on the cang gai, stirring blade and spiral under glassware set up in storage and add feed bin middle part, Li shi bottle pass through Li shi bottle mounting fixture and weighing device fixed setting. By introducing the specific storage feeding bin, the purpose that the sample cannot be scattered outside the Li's bottle is achieved; a stepless speed change motor is adopted, and the friction force and the cohesion force among powder samples are overcome through a material stirring blade, so that the continuity of feeding is ensured; the stability of the Li's bottle and the accurate control of the feeding amount are ensured through the weighing device with the clamp, and the accuracy of the measuring result is ensured.

Motor fixing device and storage add feed bin sliding connection from top to bottom, the storage is added feed bin and is fixed in feeding device support. The motor fixing device is connected with the material storage and feeding bin in a vertical sliding manner, so that the position of the motor, the spiral feeder on the lower part of the motor and the material stirring blade fixedly connected to the spiral feeder can be adjusted; the position of the material storage and feeding bin is fixed through the feeding device support, so that the material storage and feeding bin cannot generate position change in the testing process, and further, the material storage and feeding bin is prevented from being in direct contact with the Li's bottle, and errors are avoided.

The storage and feeding bin adopts a funnel-shaped structure, the middle section of the tubular part of the storage and feeding bin is provided with a valve, and the lower end of the tubular part of the storage and feeding bin is arranged in the port of the Lee's bottle.

The material poking blades are provided with arrays with different lengths. The length of the material shifting blade is also continuously reduced along with the characteristic that the inner diameter of the conical part of the material storage and feeding bin is smaller downwards; the feeding continuity is further ensured by arranging the arrays from top to bottom.
