Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology, specifically a circulating water cooling and filtration device for incineration rotary kilns. Background Technology

[0002] Rotary kiln incineration systems, as core equipment for the high-temperature harmless treatment of hazardous waste, medical waste, and industrial solid waste, are crucial for environmental protection and resource recycling. The circulating water system, a key subsystem of the rotary kiln, is responsible for cooling the kiln body, recovering waste heat, and purifying flue gas. However, substandard water quality leads to frequent equipment maintenance, reduced heat exchange efficiency, and impacts system energy efficiency and economics. Circulating water systems commonly face problems such as scaling, corrosion, and microbial growth due to the complexity of the incinerated materials and susceptibility to high-salt, heavy metal, and organic pollution from the circulating water. Traditional chemical methods for treating circulating water pose a risk of secondary pollution, while physical filtration technologies are inefficient and unsuitable for high-load operation.

[0003] Patent document CN104874222A describes an automatic filtration and cleaning device for cooling tower circulating water, including a collection box and a chain filter screen. The bottom of the collection box is provided with a discharge port. A drive motor is installed on the collection box. A cleaning brush roller and a filter screen drive roller for winding the chain filter screen are installed inside the collection box. The cleaning brush roller and the filter screen drive roller are arranged in parallel to each other. The cleaning brush roller and the filter screen drive roller are connected to the drive motor for transmission. A filter screen driven roller is installed at the bottom of the return water ditch directly below the filter screen drive roller. The chain filter screen is wound on the filter screen drive roller and the filter screen driven roller and can rotate under the drive of the filter screen drive roller. Traditional circulating water cooling filtration devices have certain shortcomings in use. Traditional chemical methods for treating circulating water pose a risk of secondary pollution. Secondly, physical filtration technology is inefficient and requires frequent replacement of the filter element. Manual filter element replacement is time-consuming and labor-intensive, making it difficult to meet the demands of high-load operation. Furthermore, it lacks an automatic filter element replacement structure and has limited functionality.

[0004] In summary, existing technologies for treating circulating water with traditional chemical agents pose a risk of secondary pollution. Furthermore, physical filtration technology is inefficient, requires frequent filter replacements, and manual filter replacement is time-consuming and labor-intensive, making it difficult to meet the demands of high-load operation.

[0005] This utility model provides a circulating water cooling and filtration device for rotary kilns incineration, which can solve the problems of traditional equipment requiring frequent filter element replacement, manual filter element replacement being time-consuming and labor-intensive, unable to meet the demands of high-load operation, and lacking an automatic filter element replacement structure. A circulating water cooling and filtration device for a rotary kiln includes a fixed base and a cooling coil. The cooling coil is fixedly installed on the upper part of the fixed base. A filter is installed on the inner side of one end of the fixed base. A turntable is sleeved on the outer surface of the filter. The turntable is movably installed inside one end of the fixed base.

The driver is equipped with a motor and gear structure. The gear and the toothed disc mesh with each other. The motor drives the gear, which drives the toothed disc, causing the turntable to rotate and complete the ring movement of the filter. After a set of filters has been used for a period of time, the filter can be replaced by rotating it.

[0008] As a further technical solution of this utility model, a drain pipe is provided on the outer surface of one end of the fixed base, and a slot for replacing the filter is provided on one side of the drain pipe at one end of the fixed base.

The inner surface of the connecting disc is provided with a threaded groove for use with the bidirectional lead screw. The bidirectional lead screw is driven to rotate by a motor, so that the bidirectional lead screw can drive the two sets of connecting discs to move towards each other simultaneously using the bidirectional thread structure. Furthermore, the setting of a single bidirectional lead screw allows for a large movement space between the first telescopic tube and the second telescopic tube. When the filter rotates between the first telescopic tube and the second telescopic tube, the filter can be moved between the first telescopic tube and the second telescopic tube, facilitating docking operations.

[0012] As a further technical solution of this utility model, the inner sides of the first telescopic tube and the second telescopic tube are provided with beveled joints. The outer surface of the beveled joint is inclined. Both ends of the filter are provided with grooves for use with the beveled joints.

During operation, the filter is inserted into the circular screw groove of the turntable using the threaded structure on the filter surface, with one end of the filter passing through the turntable. The driver contains a motor and gear structure, with the gear meshing with the gear plate. The motor drives the gear, which in turn drives the gear plate, causing the turntable to rotate and complete the circular movement of the filter. After a set of filters has been used for a period of time, the filter can be replaced by rotating it. The turntable allows for the simultaneous installation of several sets of filters, and the position of several sets of filters can be adjusted by rotating them. When the water in the cooling coil is being filtered, the service life of the filtration structure can be extended. By setting up a first telescopic pipe and a second telescopic pipe, the use of the filter and the rotating disc is optimized when the circulating water cooling and filtration device for the rotary kiln is used. This solves the docking problem after the filter is rotated and adjusted. When the cooling coil is used to replace the filter, the valve can be used to cut off the flow of the connecting pipe. The motor drives the bidirectional screw to rotate, so that the bidirectional screw can drive the two sets of connecting discs to move towards each other at the same time using the bidirectional thread structure. Secondly, the setting of a single bidirectional screw allows for a large movement space between the first telescopic pipe and the second telescopic pipe. When the filter rotates between the first telescopic pipe and the second telescopic pipe, the filter can be moved between the first telescopic pipe and the second telescopic pipe to facilitate docking. The setting of the beveled joint can connect the two ends of the filter, improving the sealing performance during filter docking and installation, and completing the docking operation at both ends of the filter.
