Roller Conveyor Type Shot Blasting Machine Direct-Coupling Blast Wheel For Steel structure Cleaning

Roller conveyor shot blasting machine

During the cleaning process of the roller type shot blasting machine, the electrically controlled adjustable speed conveying roller table sends the steel structure or steel into the ejection area of the cleaning machine room. The surface of the roller type shot blasting machine is subjected to different coordinate directions. The strong and dense projectile strikes and rubs, so that the oxide scale, rust layer and dirt on it will quickly fall off, and the surface of the steel will get a smooth surface with a certain roughness. The roller conveyor is cleaned by the roller blasting machine on both sides of the outdoor. The projectiles and rust dust falling on the steel material are blown by the purge device. The dropped pellet dust mixture is conveyed by the recovery screw to the chamber funnel, and the vertical and horizontal screw conveyor is collected at the lower part of the hoist, and then lifted to the roller table. In the separator on the upper part of the type shot blasting machine, the separated pure projectiles fall into the separator hopper for recycling use. Dust generated during the shot blasting of the roller-type shot blasting machine is sent to the dust removal system by the exhaust pipe, and the purified air is discharged into the atmosphere, and the particulate dust is captured and collected.
The difference between the H-type roller conveyor shot blasting machine and the G and HD roller conveyor type shot blasting machines is that the installation of the shot blasting device is at an angle to the direction of the workpiece inside the equipment.

Cartridge dust removal unit
During the shot blasting of the workpiece, rust and oxide scale and broken shot dust (or fine powder) will begin to form. The fine powder is separated in the shot cleaning agent, which can be adjusted according to different types and sizes of shot media. The cartridge type dust collector that generates the necessary pressure is installed on the top of the RB 600, RB 1000 and RB 1500, while the large machines above RB 2000 are installed next to the shot blasting machine.

The impact separator in the filter element filter unit not only ensures the separation of the decomposed fine powder (protecting the filter element from unnecessary wear), but is also certified as a spark extinguishing device, which is one of the elements that contribute to the realization of the ATEX regulations. The cartridge type dust collector uses air pressure pulses to automatically clean the cartridge. The intensity and duration of the pulse can be adjusted according to the type and amount of dust. All filter cartridge filtration processes are carried out without ignition.

Loading and unloading
In the basic equipment, the entrance and exit of the roller conveyor are powered by the central drive of the shot blasting machine. In order to improve efficiency, a separate drive unit can be installed, and the attached frequency converter is also automatically synchronized.

If the curved workpiece has been shot blasting but cannot be thoroughly cleaned by the rotating brush and purge point, it is recommended to use a longer collection track and recycling conveyor to help ensure that the shot can be recycled by the equipment.

By installing a horizontal feed system, efficiency can be improved in many ways. And the horizontal feeding system can be installed on the sawing/drilling production line together with the shot blasting machine.

Shot
Most roller conveyor shot blasting machines are equipped with round shots (cast steel shots or rounded steel cut shots). The pellets travel around the equipment and continuously remove contaminants.

In order to obtain a good shot blasting effect, a balanced combination of new and old shots is imperative. The finer shots used in this mixture are very important to ensure the same shot blasting coverage on the workpiece surface, and the coarser shots are also very important to remove the oxide scale.

The use of the correct shot material is especially important for the shot blasting process to ensure a good shot blasting effect

The following is the usage guide:

For rough machined workpieces (such as thick plate profiles), use a coarser shot mixture (steel shot size S390 and above)
Use fine shot mixtures (steel shot size S330 and below) for finishing workpieces (eg thin metal plates)

Shot blasting room
The shot blasting chambers of all KNNJOO roller conveyor shot blasting machines are made of manganese steel plates. The hardness of manganese steel is relatively large, and the acceptable shot blasting hardness ranges from 35 HR C to 60 HRC or higher. Therefore, HD600 has excellent shot blasting properties. In the hot spot area of the shot blasting room, HD600 wear-resistant steel plates imported from Sweden were added. They are connected externally and are easy to replace. When using shot blasting with strong impact force, manganese, tool steel or castings can be provided as linings. In order to avoid the leakage of pellets, several layers of rubber pads or Vulkolan screens are installed in the excessively worn area, which are installed on the V-shaped track for easy replacement.

In order to avoid shot blasting on the long parts, the rotating brush gently brushes the used abrasive off the surface of the workpiece and brushes it into a specially designed groove. The groove is equipped with a screw conveyor to send the medium back. To recycle. In order to keep the position of the brush and screw conveyor fixed, when the workpieces of different sizes are shot blasting, the rotating brush and screw conveyor are both set on the same adjustable frame. The frame can be adjusted manually or automatically. Within the required height range, the adjustment distance must be less than 5mm. Finally, the residual medium on the workpiece will be cleaned by a blower, which is installed on the same frame, and a high-pressure ventilator is used to blow off the residual material.

1. The use of BMD shot blasting machine with large shot blasting volume and high ejection speed can significantly improve cleaning efficiency and gain

Satisfactory cleaning quality.

2. Simulated projectile drawings (including the determination of the model, number and spatial arrangement of the shot blasting machine, etc.) and all drawings of the shot blasting machine are drawn using computer-aided design (CAD), and the selection and layout of the shot blasting machine are more reasonable . The utilization rate of projectiles and labor productivity are improved, the cleaning effect is ensured, and the abrasion of the chamber body guard plate is reduced.

3. Adopting the popular non-pit structure, which not only saves the construction cost and time of the pit foundation, but also solves the problem of southern

The problem of corrosion and agglomeration of shot sand in the hoist caused by water in the pit.

4. Cleaning the indoor hot zone adopts rolled Mn13 plate protection. Compared with the previous rubber plate protection, its service life is greatly improved, and the appearance is beautiful, and it is easy to replace. It is the most popular way of cleaning machine room protection today.
