Sand and stone gravitational pulverized machine is Yancheng City salt rich environmental protection equipment Co., Ltd. according to the customer's response and requirements, through a large number of scientific research personnel research and development of a new type of classifier, with a dust collector, no motor. The investment and use cost of the customers are greatly reduced, and it is mainly applied to the separation of the super standard stone powder in the dry sand production line, so that the mechanism sand meets the national standard.
Product features:
1. adjustment is convenient, and there are 4 regulating parts, which are control of material waterfall, primary air inlet control, two air intake control and output control, which can be very convenient to control air volume and the powder content of finished products.
2. power province, the former configuration for separator and dust removal, now this type is no motor, the main power is reflected on the dust remover, can save power input.
3. the structure is simple, the main material has few contact parts, small wear and low maintenance cost.
Working principle：
The gravity separator of sand and stone material realizes the classification of 0-4.75mm materials by changing the direction of air flow, gravity and air flow.
These devices are combined with gravity, inertia, centrifugal force and aerodynamic force to classify the materials with a particle size of 0-4.75mm. Feed and primary air enter the classifier from top to bottom. The air flow changes 120 degrees and carries fine particles away from the classifier through leaves. The coarse particles which are unable to rotate with the air mass due to their own gravity fall to the bottom of the classifier, and then are discharged through a valve.
The two air from the lower part of the blade is forced to go through the falling particle curtain. The coarse particles near the grading point are diverting to the swirl of the heart-shaped chamber by two air currents. The fine particles captured and the other particles dragged out of the eddy flow into the classifier are carried out by the outlet air to the collector (dust collector) for final recovery.
The two air throttle valve has a simple manual adjustment function, which can change the classification granularity of fine particles. There is no moving parts in the material flow range, so the maintenance requirement is the lowest. For abrasive materials, liners are used in certain areas to ensure long service life.
Product advantages:
1. the cost of maintenance and operation is low;
2. reduce water content and minimize the cost.
3. to open up the additional market for -200 mesh granularity materials.
The cloth bag pulse duster is a high efficiency dust collector, which is based on the introduction of the traditional dust collector technology and absorbs the advantages of the foreign dust remover, and combines the domestic market with the contemporary technical level. This type of dust collector, which combines the advantages of the type duster such as the back blowing and the injection pulse, overcomes the shortcoming of the low kinetic energy intensity, the pulse injection filtering and the ash cleaning simultaneously. With the characteristics of high intensity, fast speed and short cycle period, the dust collector increases the adaptability of the use, improves the dust removal efficiency and prolongs the service life of the filter bag. The dust concentration of this product can fully meet the national new environmental emission standards (emission concentration, thermal equipment <100mg/Nm3, ventilation equipment <50mg/Nm3) requirements.
Purpose: cloth bag pulse high efficiency dust collector is widely used in cement, mining, machinery, power, chemical industry, metallurgy, steel and other industries.
Product features:
1. reliable performance, ensuring that the dust collector works steadily with the crushing equipment for a long time and maintains little.
2. strong adaptability and suitable for dust laden gas in a wide range.
3. the special design, fiber filter bag and parts selection are used to make the dust concentration of the dusting meet the national discharge standard.
4. the optimized inlet and outlet design is conducive to uniform airflow distribution.
5. air leakage prevention design ensures minimum leakage rate of bag filter.
The 6. split structure design facilitates the transportation and installation of the equipment and ensures the accuracy of the equipment.
7. low operating cost and optimized process parameter design are favorable for low resistance, efficient and stable operation of bag precipitator.
8. reduce system energy consumption, and effectively reduce the loss and maintenance of filter bags.
9. the perfect serialization design can meet the needs of dust control in many kinds of dust sources.
10. standardized design can reduce the storage of spare parts for users.
11., perfect combination with gravity inertia classifier can not only achieve the effect of dust removal, but also achieve the effect of separating sand from powder.
Working principle：
The dust gas from the inlet of the dust collector enters the ash hopper in the separate chamber, and the large particles of dust are separated and directly fall into the ash bucket under the diversion of the bucket guide device, and the fine dust is evenly entered into the central box and adsorbed on the outer surface of the filter bag, and the clean gas filter bag enters the upper box and passes through the off-line valves and the valves. The exhaust pipe is discharged into the atmosphere. As the filter condition goes on, the dust on the filter bag is accumulated more and more, when the equipment resistance reaches the limited resistance value (generally set as 1500Pa), the electric control pulse valve is opened according to the setting program and the air blowing and blowing is carried out by the setting program after the control device is automatically closed to the off-line valve according to the differential pressure setting value or the setting value of the ash cleaning time. The instantaneous injection of compressed air makes the pressure in the filter bag increase, and the dust on the filter bag is shakes off (even if the fine dust can also be cleaned thoroughly) to the ash bucket, the dust removal mechanism is discharged.
