Description

Technical Field

[0002] In coal mine tunnels, it is often pitch dark, and workers can only judge each other's presence by the sounds they hear, which poses a great threat to safety and health. In order to solve this problem, wet dust collectors are valued for their efficient purification capabilities and adaptability to complex environments. This equipment can effectively purify dust-laden gases with high humidity, and has become an important technical means to achieve dust concentration standards in mines and dust-free mine construction. However, existing wet dust collectors require the use of water sources that meet standards. Poor water quality or insufficient water pressure will affect their dust removal efficiency, thereby reducing the overall operating effect. In addition, the nozzles, filters, vibrating plates, baffles and other components in the equipment are prone to clogging. The workload of cleaning and maintaining these components is large, and they often need to be disassembled frequently, which brings inconvenience to daily operations. As the nozzles, filters and other components gradually become clogged, the processed air volume will continue to decrease, resulting in a significant reduction in the dust removal effect, thereby affecting the safety of the mine environment. At the same time, dirt and sediment will accumulate on the inner wall of the dust collector casing. The accumulated dirt and sewage will cause corrosion of the inner wall, shortening the service life of the equipment and the dust removal efficiency. Excessive accumulation of dirt will also cause secondary pollution, affecting the surrounding environment and the health of the staff. Utility Model Content

The outer ring of the slewing bearing 10 is connected to the shell, and the inner ring is connected to the dehydration drum 9. The input end of the slewing bearing 10 is connected to the output end of the motor. The diameter of the dehydration drum 9 of the first dehydrator 7 is equivalent to the inner diameter of the casing 1, so that the dust-containing The water flows into the dehydration drum 9 and is then dehydrated. It also includes a conical guide block, which is arranged at the air inlet end of the impeller 101. The conical end of the conical guide block is coaxially arranged with the water inlet pipe 2. The conical guide block is located at the air inlet end of the impeller 101, and is used to optimize the angle of the airflow entering the impeller 101 and improve the efficiency of the fluid flow. A support ring is connected to the outer circumference of the explosion-proof motor, and the support ring is connected to the explosion-proof motor and is connected to the inner wall of the casing 1 through a support column to provide additional stability. Support columns are symmetrically arranged on the upper and lower ends of the support ring, and the support columns are connected to the inner wall of the casing 1. There is a swirl blade 102 between the inner wall of the casing 1. A connecting frame is provided, which provides support for the swirl blade 102. The connecting frame is connected to the inner wall of the casing 1, and a bearing seat is provided between the contact end of the swirl blade 102 and the connecting frame. The bottom ends of the casing 1, the first dehydrator 7, and the second dehydrator 8 are all provided with a sewage outlet 5, which is used to discharge sewage or sediment inside the equipment to ensure the normal operation and cleanliness of the equipment. The impeller 101 rotates at high speed driven by the motor to generate a supergravity field. While the dust-laden airflow is sucked in at a high negative pressure, the water flow entering the water supply pipe is fully broken and atomized to form a high-energy water curtain, which performs a "single-stage" purification on the dust-laden airflow; Swirl dust collection section: powder The dust is fully captured by the impeller 101 wheel and the large-area water film on the inner wall of the casing 1 through the "double inertial separation effect", realizing dust transfer and mass transfer, and performing "double" purification on the dust-laden gas; the swirl blades 102 convert the straight path of the dust-laden airflow into a curved path that moves spirally around the inner wall of the dust collector, increasing the distance and time for the combination of dust and droplets. The dust collides with the water film on the swirl blades 102 and is further captured, thus performing "triple" purification on the dust-laden airflow; diffusion dehydration section: under the action of spiral centrifugal force and gravity, the sewage is thrown to the inner wall of the dehydrator to separate the sewage and clean airflow, and the clean airflow is discharged from the dust collector outlet.

[0030] It breaks the design concept of traditional wet dust collectors that use nozzles and various filtering components to capture and remove dust, fully integrates the centrifugal atomization mechanism with the cyclone separation mechanism, improves the dust removal efficiency and equipment reliability, and fundamentally eliminates the problems of nozzle clogging and filter cleaning. It has no requirements for water quality and water pressure, and is convenient for maintenance throughout the life cycle. It fully integrates the dust collection function of the fan with the dust removal function of the dust collector. The impeller 101 is both a power device and plays a role in atomization and dust collection, realizing a high degree of integration of the dust collection and dust collection structure of the dust collector. The two-stage dehydration device designed according to the movement trajectory of the dust-laden airflow maximizes the dehydration effect and avoids secondary pollution caused by the discharge of dust droplets. The whole equipment adopts a special impeller 101 combined with the axial casing 1 design, which organically combines the high negative pressure advantage of the impeller 101 with the structural advantage of the axial casing 1. While ensuring the dust collection capacity of the equipment, the volume of the equipment is minimized to facilitate the movement and use of underground personnel.

[0031] Example 2: Please refer to Figure 6-7 , based on Example 1, further comprising the following structure:

When cleaning is needed, the driving motor is driven to rotate the rotating wheel 103, and the rotating wheel 103 drives the connecting wheel 104 to rotate. At the same time, the connecting wheel 104 slides in the groove body of the shell 105, so that the shell 105 moves.
