Slide 1
Building the walls of the slurry tank [[Image:]] |
Hello everyone.
Welcome to this Spoken Tutorial on building the walls of the slurry tank. This is an activity to be done on Day 2. |
Slide 2
Learning Objectives
|
In this tutorial, we will learn-
|
Slide 3
Building the walls of the slurry tank What is a slurry tank? |
Let’s first understand what is a slurry tank. |
Image |
Slurry-
2. This slurry comes out of the digester tank and is collected in the slurry tank. |
Slide 4
Building the walls of the slurry tank Position of the slurry tank? |
Let’s look at the position of the slurry tank with respect to the Biogas plant. |
Image | The slurry tank is placed-
|
Slide 5
Building the walls of the slurry tank Shape of the tank? |
What is the shape of the tank? |
Image | These tanks are rectangular in shape. |
Image
Arrows at the upper tank and the smaller tank. |
What you see here is the pictorial representation of the slurry tank.
|
# Entrance view of this image
|
Notice-
2. Also note, the upper tank has an outlet hole. 3. The lower tank is in line with the entrance to the digester tank. |
Slide 6
Building the walls of the slurry tank How many walls have to be built for constructing the slurry tank ? |
So, in total, how many walls have to be built for constructing the slurry tank? |
Image | Total 7 walls have to be constructed to build the slurry tank.
The various dimensions are shown in the image. |
Image |
Items used for construction are
|
Image |
To begin with,
|
Image | Insert these steel rods through sufficient number of holes.
|
Image |
Next, lay a plastic sheet on the ground. |
<center>[[Image:]] |
Use a measuring tape to mark boundary for-
|
|
We will spread the cement mixture within this boundary, on the plastic sheet. Prepare cement mixture as follows-
Note- that no gravel is used in this mixture. |
|
To begin with,
|
|
Now carefully-
2. This chicken mesh with inserted steel rods serve as-
|
Care should be taken to-
2. This will be entwined or interlocked-
3. Doing this will help fixing the walls of the slurry tank with the dome. | |
|
In the earlier two images, we saw-

Slide 7 Building the walls of the slurry tank Significance of a hole in one of the walls of the slurry tank. |
Now let’s talk about the significance of this hole. |
[[Image:]]
[[Image:]] |
It is this hole from where-
|
Slide 8
Building the walls of the slurry tank How to make a hole in the wall of the slurry tank? |
So how to make this hole in the wall of the slurry tank? |
|
To make a hole, use the inlet pipe of 6 inches diameter.
|
[[Image:]] [[Image:]] [[Image:]] |
To begin with:
2. Then insert the Steel rods as explained earlier-
3. Now lay this mesh with a hole-
4. The thickness of this cement mixture should be 1.5 inches. |
|
Exactly on this hole-
Before placing it, please remember-
|
|
As each step is followed by another in quick succession, the mason should plan well.
|
Now, spread cement mixture around the pipe, using the small trowel.
| |
Note that the pipe will be removed when the cement is dry. | |
[[Image:]] |
After the pipe is removed, this is how the hole would look like |
[[Image:]] |
The prepared walls are left for drying for two days and will be used on day 4. |
This brings us to the end of this tutorial | |
Assembly of the walls of the tank will be explained in a later tutorial. | |
Slide 9
