INTRODUCTION

The Industrial Cleaning today is a major problem. Each cleaning problem is unique from other because of many variables in a manufacturing process. Integrating the cleaning process with production and plant requirements through a proper equipment sizing and selection is very important. This machine is more preferred over the existing machine like less cycle time, less operating cost, economical for small surfaces and less maintenance cost.

This Special purpose machine (SPM) is not available in the market. Therefore they have to be designed as per the costumer requirement. They are also called as bespoke machines. This special purpose machine (SPM) is operating continuously for 24 hours a day, with minimum cycle time. The special purpose machine is generally used to washing of specific component. These special purpose machine (SPM) are used hydraulic and pneumatic energy. This machine is operating automatically or manually.

The productivity achieved after all the equipment is very high. Productivity of product is increase by 3 to 10 times than other washing. This industrial washing machine is a special purpose machine which is manufacturing for special purpose. This machine is designed according to the need as per the component to be washed for e.g. In various industries different jobs are manufacturing and as per the job the machine is designed. In this machine various sensors are provided which indicate and also reduce the chances of operations failure and assures the safety of operator.

This machine helps in quick operations as well as good performance. This machine highly cleans the job which is to be washed. This minimizes the time and this can be used in small as well as large scale industry. Purpose machine is a high productivity machine, with specially designed tooling and fixture, dedicated for mass producing the same component day in and day out. In this machine there are combination of limit switches, sensors, controller, and other safety devices etc. the essence of a SPM. A well-conceived Special Purpose Machine finds ways and means to utilize the man and machine to the optimum.

In this Special purpose machine (SPM) there are various components are used such as pump, blower, nozzle, filter, oil skimmer, tilting mechanism, water level indicator, temperature switches, etc.

      II THEORY

      This industrial washing machine is made for washing of specific components which are critical to wash or which cannot be washed by other method. Design of the machine is designed according to the use of machine, the environment in which the machine is used, in which type of industry it is being used. The main components of this are motor, pump, tank, filter, safety valve, and washing cabin. The machine is provided with stator, sensors etc. the A.C current is supplied to the stator circuit, this circuit consists of start and slop switches and internal connections The machine is start by the start button indicated by green color, by pressing this button the machine starts.

      Pump is pumping the water from the clean tank and to supply the nozzle. Then the distance between the nozzle and components are specified then wash the components on the both side. Water from the washing components is flow to the dirty tank with the mixture of various lubricating fluid such as (grease, oils, wax) the capacity of the dirty tank is more than the clean tank. Water level indicators are used in both tanks to indicate the water level in the tank. In the clean tank two water heaters are used to heat the clean water the temp of the water in the clean tank in between 95c0 to 65c0 the temp. Of the water below than 55c0 then water heater is start automatically.

      Using water heater in the tank to increase the temp. of the water then some amount of oil and other fluids are present in the water then increase the temp. of the oil then viscosity of the oil is reduced and easy to wash the crates with less time.

      Oil skimmer are used in the dirty tank to remove the oil in the tank when the operations is start then oil skimmer is stop. In the operations water wave are present in the tank then oil mixed with the water. Operations is stop then oil in the water

      float above the water and easy to remove with the help of chain type oil skimmer. One additional transfer pump is used to pump the water from the dirty tank to filter to clean tank. The duplex type filter is used to remove the water partials with filtrations capacity up to 300 micron. One standby mode because of cleaning of filter and choking of the filter then filter water id passed to the clean tank. Two parts are providing to both the tanks to remove the water and supply the press water with the specified period. For the drying of component blower with some arrangement are used. Blower is fitted to bottom of the cabin and on the frame. Tilting mechanism is used to hold the component in the cabin. During the operations movement of the tilting mechanism with the help of some arrangement on the cabin such as motor, reductions box, flange, chain, and sprocket and L type link is used.

      One additional cylinder & piston arrangement is provided to up & down movement of the assembly for proper cleaning of the component. During the washing of component nozzle speed water to the component and small water drops are mixed with the work environment and dangerous to the operator by eliminating this problem we use mist eliminator.

      Total cycle time of the operations is 3min to washing of components is 2 min and drying 1min.

      III DESIGN OF MACHINE COMPONENTS

      In this topic, some important points have been discussed which are useful in the washing machine

  5. CAD MODEL OF TILTING MECHANISM:

  7. CAD MODEL OF TANK:

    Clean Tank;-The tank is mounted on frame, and on tank motor, pump, and filter are mounted .The tank is having four lids

    The tank used in industrial washing machine is made up of SS 304(stainless steel) material. The sixteen gauge SS sheet is used for tank .The storage capacity of the tank 673.5 liters.

    The capacity of the clean tank is less than the capacity of the dirty tank.

    Dirty Tank- Dirty tank is made for this machine is tapered at the base. This taper is provide for easy cleaning of tank for e.g. While washing components the impurities wash out are collected into tank along with water, because of the taper this impurities slide along the taper and comes towards the slope

    Between the pump and washing chamber the cage is provided. this cage prevents the impurities or any part of components fallen into the tank .The storage capacity of the tank is 845 litters
