Abstract:

In process control industries, controlling the liquid inside the non-linear tanks such as a conical tank, hopper tank and spherical tank is a highly challenging task due to the change in the cross section area of the tank. The aim of this project is to design a suitable controller to control the level of the hopper type tank by using conventional controllers like Ziegler-Nichols tuning method (ZN) and computational controllers using metaheuristic algorithms such as Bacteria Foraging Optimization (BFO) algorithm, Particle Swarm Optimization (PSO) algorithm and Firefly Algorithm (FA). This contr

Dependences that allow to determine the temperature of nutrient medium in the hopper of mixing and fermenting tank with regard to the design parameters of machine are obtained. Based on the results of experimental research, the observed dependences of change of specific energy consumption are obtained; the optimum parameters of angles of tank wrapping by heat tape and level of tank filling by nutrient medium are determined.

Abstract:

Abstract In industrial production for the storage or processing of various bulk materials such as compound feed, grain, coal, crushed stone, sand, rocks, etc. use different containers and bins. Depending on the physical and mechanical properties of materials, containers and bunkers of various types are used. When designing tanks and bunkers, various engineering solutions are used to save material and reliable strength of the entire structure of tank structures. One of these solutions is the installation of stiffeners on the surfaces of the hoppers, which gives additional rigidity to the entire

Abstract:

The secondary settling tank is an essential unit for the biochemical treatment of domestic sewage, and its operational effect influences the quality of effluent. Under the influence of the confluence of rainwater and sewage, wastewater use habits, etc., the inflow of the secondary sedimentation tank changes over time. In this paper, OpenFOAM, an open-source computational fluid dynamics package, was used to study the dynamic behaviors of solid–liquid two-phase flow in the tank under influent flow rate variations.

Abstract:

Abstract The main thing for rotating equipment is to measure vibration, since, in the process of irreversible state change, a chain of defects always occurs and at least one of them significantly changes the vibration of the equipment. Using tank scales for static equipment, the vibration measuring makes it possible to determine the actual values of the levels and compare them with the maximum permissible values set by the manufacturer or regulatory documents. Also, the measurement of vibration levels in the time signal allows determining resonant frequencies at which vibration levels signific

Abstract:

Instead of a planned two stage activated sludge plant the design was changed to a single stage activated sludge plant with enhanced biological phosphate removal and pre-anoxic zone denitrification. For flexible operation it is possible to vary the rato of VD/V from 0.3 to 0.5. Problems with the aeration equipment in the nitrification/denitrification cells occurred and were solved. The circular clarifiers are equipped with scrapers. Instead of a sludge hopper a collector in the centre of the tank was constructed.

Abstract:

In this paper, we present the results of engineering design of components of a grain hopper and a bucket elevator for a combined unit for soil preparation and sowing of grain crops. The grain hopper has compartments for seeds and fertilizers. A coil-type metering device is also separated for seeds and fertilizers. The drive of the metering device for seeds and fertilizers is done by the rear wheels of the rolling device through a variator, which also serves to adjust seeds supply. On the same shaft with the metering device there is a sprocket, which transmits rotation moment to the bucket elev

The conventional methods of supplying feed to tilapia tanks are ineffective. It is better to find new a automatic feeder saving pellets from crushing and cohesion without hitting pellets during feeding at a predetermined interval of time and an accurate amount of food with a larger surface area covered by pellets. Developing-country fish farmers use manual feeding to be more cost-effective than with costly mechanized feeding, so this research aimed to design and construct an automatic fish feeder prototype to feed tilapia in a recirculation aquaculture system’s tank.

This process might involve forced heat and ventilation but is not often precisely controlled and even less often are details of the process documented.
