The first element of the mechanical pre-treatment, grinding equipment is of key importance in the process of purification, in a wastewater treatment plant as pe in the water treatment process.

The aim is to achieve the highest possible degree of separation under hydraulic constraints. In plants, wastewater treatment, often requiring the return of the soluble to water flow in order to incorporate this organic substrate to the biological stage.

Hygiene in the operation, reliability in operation and maintenance in the shortest possible are other considerations that are increasingly gaining importance.

Solution:

TCT-020 works under a unique system which performs the functions of grinding, washing, extraction, drying and pressing into a single computer.

Depending on the step of the sieve (0.5 to 5 mm) and sieve size can be different amounts of flow.

TCT-020 is made of stainless steel.

The equipment can be placed in a channel, or stainless steel in Cuba. TCT-020 is capable of performing a screening or process wastewater with minimal steps directly into the channel, without need for pumping.

Operation:

TCT-020 is installed with an inclination of 35 degrees, or in a container or directly into a channel. Water enters the drum head on and through the wedge profile screen, remaining settleable solids, floating supernatants retained in the mesh. With the formation of a layer of waste, an additional effect of filtration, carried out by the blanket of denial. The specific form of wedge profile mesh ensures that the solids are retained at the inside of the drum, without actually clog the mesh.

Upon reaching a certain difference in height of water, starts the self-cleaning mechanism. The drum starts rotating, transporting waste to the top and making them fall by pressurized water and a brush disposed therein to a hopper at the center of the drum. From there, a screw transports the material to the roughing exhaust pipe.

Wash system handles waste at this point to extract the soluble solids of grinding material and reinstate the flow of water filtered. The screw transports extraction, dehydration, compact waste and deposited in a container, Cuba, basket … The degree of dryness in the residue obtained is 40% DM.

Advantages:

1 – Large capacity grinding.

2 – Low pressure drop.

3 – Complete set of stainless steel.

4 – Flow bound.

5 – multiple functions.

6 – Subsequent extensions

7 – virtually maintenance-free equipment.

The auger screen TDT-020 ® is a combined team for the separation of the solids present in wastewater and the subsequent compaction and dehydration of the same. The solid material in suspension in the transport fluid is deposited on the screen clogged, which causes an increase in level at the front of it and a decrease in the back. At that time begins to run the propeller, which cleans the screen, turn up the material, dehydrated and compact.

The team consists of the following parts:

- Sieve filter.
- Augers.
- Compactor.

The screen filter is formed by a screen with light passing between 0.25 and 10mm which retains the suspended solids in the liquid transport. This screen is kept clean thanks to the corresponding brush set on the outside of the helix.

The screen can be of two types:

- Strainer Johnson profile between 0.25 and 2mm.
- Perforated sheet strainer or triangle between 3 and 10mm diameter holes.

The auger consists of a propeller shaft that can lift without solids deposited. Without shaft auger to extract materials of varying shape and size, which are otherwise difficult to transport.

The compactor itself serves to transport helix compaction-dehydration effect of screening, resulting in a reduction in the volume even higher than 50%.

Your advantages:

1 – Fully automatic, with the possibility of varying the rotation speed as needed.
2 – Output hopper screened solids, length depending on application.
3 – solid compaction system screened, this system includes a wash rack compaction, which prevents clogs the grate and facilitates water runoff.
4 – The tilting system allows us to examine the state of both the grid filter, and the helical thread at any time.
5 – This area is simply threaded transport screened solids, which are aimed at the head of compaction, the thread becomes soulless tube.
6 – Grid filter, possible execution profile Johnson, perforated or triangular in steps of 0.25mm to 10mm.
7 – Specially designed spiral coil which incorporates a brush wear, this is what makes the screening of solids.

(NOTE: As an option we can introduce a cleaning system on the grid filter)

The water / sand was pumped into the spiral classifier, given the special design of the entrance and the shape of the tank, creating a laminar flow, which favors a good decanting. The solids settle to the bottom of the Cuba and the conveyor rises slowly particles (less recommended rotation speed of 5 rpm).

Without turbulence have the water removed and drained before the download. There is danger of blockage by floating materials are easily removed. The water comes out of overflow to the head of plant.

Applications:

- Treatment treatment plants.

- Industrial pulp and paper.

- Recycling plants.

- Food-processing industry, vegetable and fruit processing. – Etc. ..

Screw Conveyors are the solution for the transport of very diverse

- Materials muddy, semi-fluid, viscous, etc …

-fibrous products, binders, etc …

- or irregular materials tend to form arches, etc …

Screw Conveyors differ coreless screw conveyors classics,

First .- The auger is a spiral conveyor without shaft, built in stainless steel AISI 304 or 316, thickener strong and robust.

Second .- The design spirally central axis allows the endless conveyor have a greater capacity transport.

Third .- The behavior or fibrous materials tend to agglomerate and transporting highly variable grain products, is very favorable because nothing slows the progress of the product and can be filled without danger of blockage.

Fourth. - Screw Conveyors, may work by “pushing” or “pulling”.

Fifth .- Screw Conveyors The facilities are very compact and occupy very small space.

Sixth .- Supplementing the spiral can increase the slope of work and increase rigidity large auger conveyor lengths.
