Application of Vacuum Pumps Supporting Brick Making Machines

Vacuum pumps are the core supporting equipment in the production process of brick making machines (especially vacuum extruders), and their performance directly determines the forming quality of green bricks, production efficiency and the stability of equipment operation. In the brick and tile processing industry, water ring vacuum pumps have become the mainstream supporting choice for various brick making machines due to their outstanding advantages such as strong adaptability, stable operation, energy conservation and environmental protection. They are widely used in the production of solid bricks, hollow bricks, porous bricks and new-type environmental protection bricks, running through key links such as brick machine forming and auxiliary drying, and are important support for ensuring the qualification of brick and tile products and realizing large-scale production.

I. Core Application Scenarios of Vacuum Pumps Supporting Brick Making Machines

The core production process of brick making machines mainly includes raw material preparation, extrusion forming, drying and roasting. The application of vacuum pumps is mainly concentrated in the forming link, and at the same time provides auxiliary support for the drying link. Its core function is to build a stable vacuum environment, solve the industry pain points such as insufficient density of green bricks, easy cracking and low production efficiency, and adapt to the needs of continuous and large-scale production of brick making machines.

(I) Core Scenario: Supporting Forming of Vacuum Extruders

Extrusion forming is the core process of brick making machine production. Vacuum extruders rely on a stable vacuum environment to completely discharge air, water vapor and impurities from raw materials such as clay, shale, gangue and fly ash to ensure that green bricks are dense, free of pores and not easy to crack. After starting, the water ring vacuum pump forms a stable vacuum, accurately connects with the vacuum chamber of the extruder, efficiently sucks air from raw materials, ensures the quality of green bricks, and is the standard configuration of vacuum extruders.

(II) Auxiliary Scenario: Exhaust Suction in Drying Link

After the green bricks are formed, they need to enter the drying kiln for dehydration. If a large amount of water vapor generated in the process cannot be discharged in time, it will lead to bulging of green bricks and uneven water content. The vacuum pump is connected to the drying kiln through pipelines to quickly suck water vapor and waste gas, accelerate dehydration, stabilize the temperature and humidity in the kiln, shorten the drying cycle, reduce energy consumption, and seamlessly connect with the production process of the brick making machine.

(III) Special Scenario: Supporting New-type Environmental Protection Brick Making Machines

For environmental protection considerations, environmental protection bricks such as fly ash bricks and desulfurized gypsum bricks have become the mainstream. Their raw materials contain industrial waste residue, which is prone to generate dusty and corrosive gases. The water ring vacuum pump can directly suck such gases and introduce them into purification devices to reduce pollution. At the same time, it ensures production safety by virtue of its isothermal compression characteristics and adapts to the production needs of environmental protection brick making machines.

II. Selection and Advantages of Vacuum Pumps Supporting Brick Making Machines

The selection shall match the production scale and raw material characteristics of the brick making machine: single-stage single-acting water ring vacuum pumps are suitable for small brick making machines, single-stage double-acting models are selected for medium and large extruders, and double-stage or customized models are preferred for environmental protection brick production. Its core advantages lie in adapting to the dusty and high-humidity environment of brick making machines without additional pretreatment; stable operation to ensure the quality of green bricks; circulating use of clean water to save energy and reduce consumption; simple operation and maintenance to reduce labor costs.

III. Application Notes

To ensure the stable linkage of equipment, clean water shall be selected as the working medium, and the circulating water shall be regularly inspected, supplemented and replaced; the vacuum degree shall be adjusted according to the raw materials and green brick specifications to avoid affecting the quality of green bricks; the pump chamber and filter shall be cleaned regularly to prevent dust wear; the connecting pipelines and seals shall be inspected regularly, and derusting and anti-corrosion treatment shall be done on the pump body to ensure long-term stable linkage with the brick making machine.
