Construction Of The Spin Dryer

Electrical Electronics Engineering | Industrial Physics | Physics

The construction of a spin dryer involves the assembly of various components designed to efficiently remove excess moisture from laundry through centrifugal force. Typically, a spin dryer consists of a cylindrical drum made of durable materials such as stainless steel, equipped with perforations or slots to facilitate water drainage. Inside the drum, there is a motorized mechanism responsible for rotating it at high speeds. This motor is often accompanied by a belt or gear system to ensure smooth and consistent rotation. Additionally, a drainage system is integrated into the design to channel the extracted water away from the clothes. Some spin dryers may feature adjustable settings for spin speed and duration, allowing users to tailor the drying process to different fabric types and moisture levels. Safety features such as automatic shut-off mechanisms and stabilizing feet are also commonly included to enhance usability and prevent accidents. Overall, the construction of a spin dryer embodies precision engineering, combining sturdy materials and advanced mechanisms to achieve efficient water extraction while minimizing energy consumption and operational noise.

This work is aimed at designing and fabricating a spin dryer which can be used in drying clothes after brewing. This will no doubt save considerable human labours and time wastage involved in conventional method of drying the spent grains by spreading on the ground. It also saves as a means of employments for our teaming population. This machine was designed after due consideration of its ease of production, maintenance and servicing.

Development of spin Dryer Machine is a project that suggested by the lecturer Faculty of Mechanical Engineering for Final Year Project title. This project focusing in designing and fabricating including develop the system and also the body structure. The objective of the project is to develop and improve the Clothes Dryer Machine. To achieve the project objective, the Clothes Dryer Machine needs to have all the criteria including aspect of strength, safety and ergonomic. To making the project a success, flow of work should been follow start by designing, analysis and lastly fabricating.

Diploma Final Year Project will take the whole semester to complete this project. This is an individual project that the candidate has to do it by ourselves. This project also give the opportunity to the candidate to apply their knowledge’s and skills in using either machinery or even computer software for designing and analysis. In this project, time management is the important things to make sure the project is done correctly according to the planning. It also a step to run the progress better and in the linear progress works. So, overall from this project is to make a superior project we need high discipline and also candidate interested to finish this Final Year Project.

1.0 INTRODUCTION

1.1 IDENTIFICATION OF NEEDS

Machine design is the creation of new and better machines and improving the existing ones. A new or better machine is one which is more economical in the overall cost of production, operation and maintenance.

It is on these background that we came out with a design of a machine, which shall help in solving problems of drying clothes.

The major problem facing homes in the country in how to dry clothes quicker after washing. Though some breweries use these spent grains as aids by drying and burning them. We hence see this method of recognition as not being economical but wasteful.

There propelled us to designing a new method of drying these spent grains to the required moisture content through the use of a SPIN DRYER. When these spent grains are properly dried, it could be a major constituent in the production of poultry feeds.

With this spin dryer, the unemployed masses could gain jobs by fabricating or buying this machine for drying of clothes, other applications include spent grains, and recycling it to a useful feed for poultry.

It is worthy to note that the production of a spin dryer is designed in a way that even the unskilled workers could operate it, in fact, we are designing this project as our quota towards the eradication of unemployment and poverty, which this present government is wedging war against.

Moreover, technology could be bought, borrowed or stolen. Our project is a borrowed technology from the western world, which was primarily used for drying of clothes, but we have expanded this scope to deal favourably with drying of clothes to the desired moisture content.

1.2 PROBLEM STATEMENT

The problems that usually face in current time is base on the customer need. Although this Final Year Project not willing to compete with the product nowadays but it apply our skill to develop machine that can fulfill the needed. Usually the issues that always been claims are:

The product must be economic and efficient in
Must be energy

The type of machine also must be consider although gas or electric

How hot the machine can produce and how long it will take time to dry the
The size also take place, bigger is not necessarily when it comes to clothes The looking of the dryer machine.

1.3 THE OBJECTIVES OF CONSTRUCTION

This project is designed and constructed to achieve the following goals:

To design and construct a spin dryer that will dry clothes.
To design and construct a machine that can dry rapidly trough spinning.
To design and construct a machine that will have high degree of automatization.
To design and construct a machine that will take less drying time.
To design a machine that will be easy in construction but have high efficiency.
To design and construct a machine that will be cheap to operate and maintain.
To design and construct a machine that will require less energy.
To design and construct a machine that could impress on existing design taking into cognisance, areas of need.

1.4 IMPORTANCE AND SPECIFICATION OF THE PROJECT

The importance attached to the design of the spin dryers is to achieve a fast spinning and drying system for drying of clothes.

The machine is design in such a way that it does not require squeezing presses to demoisture the clothes in the perforated spin tub/basket rather works on the theory of centrifugal motion where the spent grains are spin in the machine away from the centres of rotation at high velocity rate, squeezing the water out.

This machine is design to remove excess water from clothes in minutes (it spin almost at a rate of 145orpm) by spinning twice the capacity of a normal dryer. It is designed to have a longer life span and efficient in its operation. It is driven by a 4kw (5h.p) motor, as the motor is spinning the basket, the moisture content is drain to the drum. The drum encloses the basket which is covered to prevent the moisture content from splashing. Also a mesh is also provided in the spinning tub to prevent escape of clothes during spinning.
