2. Metal pipe-
 
−
* To be connected from the center of the dome- 30 cms x 1 inch diameter
 
  
−
* This will be the main gas pipe

Pour sand up till the brim of the structure.
  
−
* The length of this pipe will depend upon-
+
 
−
* the distance between '''Biogas plant '''and the kitchen

−
*Should be 6 inches diameter and approx. 5 feet of length

−
* To be connected from slurry tank to the slurry collection pit
+
1. Sand- 75 kgs

−
| style="background-color:transparent;border:0.75pt solid #000000;padding:0.071cm;"|
+
  
−
If the outlet pipe is not required, alternately, construct a drain-
+
3. Liquid waterproofing material - 50 ml thoroughly stirred in 10 ltrs of water.
  
−
* Between slurry tank and the slurry collection pit as shown.  
+
4. And adequate water to mix the mixture well
  
−
* The depth of this slurry collection pit can be between 4 to 6 feet.
 
  
−
* The slurry collected in this pit can be manually poured in the fields.  
+
Note- that no gravel is used in this mixture.

7. Approximately, 6 mtrs of rubber hose pipe of ½ inch diameter.
+
  
−
This rubber hose pipe will be used to convey the gas-
+
| style="border:0.75pt solid #000000;padding:0.071cm;"| Finally smoothen the plastering using a wooden trowel.
  
−
* from the safety valve to the kitchen stove

Construction of the mixing tank

[[Image:]]

Hello everyone and welcome to this Spoken Tutorial on construction of the Mixing tank.


This is an activity to be done on Day 2.

Slide 2

Learning Objective

We will learn :

  • Significance and shape of the mixing tank
  • How to construct a mixing tank
In this tutorial, we will learn-
  • Significance of the mixing tank.
  • How to construct a mixing tank.
  • Let’s first understand-

the Significance of the mixing tank and shape of the mixing tank.

[[Image:]]

Show the dimensions on this image

Mixing tank is where-
  • Biomass is mixed with water and passed into the digester tank.


The mixing tank is usually cylindrical in shape.

Image of mixing tank[[Image:]]

1. A mixing tank of height 2 feet and diameter 22 inches -

  • has the capacity to hold 25 kgs of manure mixed in water.

2. However, dry manure should never be put into this tank.

3. Manure should always be mixed in equal quantity of water.

[[Image:]]
  • for example, 25 kgs of manure should be mixed in 25 liters of water.
  • this will ensure free flow of the Biomass into the digester tank.
Slide 3

Construction of the mixing tank.

Let’s see the construction of the mixing tank.
Slide 4

Construction of mixing tank

For construction following items are used:

[[Image:]]

For construction, following items are used-

1. Weldmesh sheet- thickness 16 gauge

2. Newspaper

3. Sand

4. Cement

5. Liquid waterproofing material

Slide 5

Construction of the mixing tank

Step by step procedure to construct the mixing tank

The Step-by-step procedure to construct the mixing tank is as follows-

[[Image:]]

Spread the Weldmesh sheet of 69 inches x 24 inches on the ground.


Next, at a distance of 34 inches from one end of the sheet-

  • make a hole of size - 4 inch diameter with a metal cutting scissor.
[[Image:]]

Now tie the loose ends, end to end with steel wire.


We need to make a cylinder like structure-

  • with diameter 22 inches and height 24 inches.
[[Image:]]

Arrow towards the hole at the base

Note that the hole has to be at the base of the mixing tank.
[[Image:]]

Now, place newspaper or any other paper inside the structure.


The paper will help hold the sand that will be filled inside this structure.

[[Image:]]

Pour sand up till the brim of the structure.


This will give firmness to the mesh while plastering the outer wall.

[[Image:]]

Now, we will plaster the outer wall of the mixing tank.


Prepare cement mixture as follows-

1. Sand- 75 kgs

2. Cement-25 kgs

3. Liquid waterproofing material - 50 ml thoroughly stirred in 10 ltrs of water.

4. And adequate water to mix the mixture well


Note- that no gravel is used in this mixture.

[[Image:]] Start plastering the outside wall of the mixing tank as shown here.
[[Image:]] Finally smoothen the plastering using a wooden trowel.

The mixing tank should be left overnight for curing.

[[Image:]]

Next day, take out all the sand placed inside the mixing tank.


This must be done carefully-

  • so as to not break the plastered outer wall of the mixing tank.
[[Image:]]

[[Image:]]

1. Once the sand is taken out, plaster the inside wall of the mixing tank.

2. Prepare fresh cement mixture as was prepared for outer wall of the mixing tank.

3. Spread half inch of this mixture on the inside wall

4. While plastering, please remember the position of the hole that is at the base-

  • we need to break the plaster from here, later.
[[Image:]]

Arrow at the hole the base

Let the plaster on the inside wall dry for 6-7 hours.


After 6-7 hours, remove the plaster at the position of the hole by slightly tapping it.

At this point the mixing tank is ready to be transferred to the actual plant site.

Remember-

  • The following has to be completed on same day i.e day 2 of civil work
  • Hence, the mason has to plan accordingly.
This brings us to the end of this tutorial.
Assembly of the mixing tank for the Biogas plant will be explained in a later tutorial.
Slide 6

Summary

In this tutorial, we have learnt:

  • Significance and shape of the mixing tank
  • How to construct a mixing tank
Let us summarize,

In this tutorial, we have learnt-
