[0002] Rotary kilns are common industrial kilns, widely used in metallurgy, metallurgical waste recycling, incineration of municipal and industrial waste, and volatile metal smelting.

[0003] In a multi-functional rotary kiln, the dust collection chamber is used to recover dust and other particulate matter from the flue gas. A cooling water tank is installed above it, and a forward surface cooler is connected to the dust collection chamber cooling water tank through a herringbone pipe. The cooling water tank cools the medium in the pipe. However, the existing dust collection chamber cooling water tank has the following disadvantages:

A pipe 2 is inserted through the middle of the tank body 1. A liquid level switch 3 is installed in the middle of one side of the inner wall of the tank body 1 to detect the water level. A temperature control switch 5 is installed at one end of one side of the inner wall of the tank body 1 to detect the water temperature. A water pump 6 is fixedly installed at one end of the tank body 1 away from the liquid level switch 3. The input end of the water pump 6 is fixedly connected to a water inlet pipe 7. The output end of the water pump 6 is connected to the inside of the tank body 1. A filter mechanism 14 is installed at the other end of the tank body 1 away from the liquid level switch 3. A solenoid valve 9 is installed on the side wall of the filter mechanism 14 to control the discharge of water in the tank. A water outlet pipe 8 is installed at one end of the solenoid valve 9. A cleaning mechanism 12 is installed on the top of one side of the inner wall of the tank body 1 for cleaning the scale accumulated at the bottom of the tank. The cleaning mechanism 12 includes a horizontal shell 121, a reduction motor 122, a lead screw 123, two stroke blocks 124 and two scrapers 125.

[0027] In use, a herringbone pipe 2 is connected to the end of the surface cooler, which passes through the cooling water tank and connects to the dust collection chamber. A temperature control switch 5 is installed in the cooling water tank of the dust collection chamber. When it detects that the water temperature in the tank is too high to support the cooling work, it will control the solenoid valve 9 to open and discharge the water in the tank 1 from the outlet pipe 8. When the level switch 3 detects that the water level in the tank is low, it will control the water pump 6 to start and draw external water into the tank, thereby automatically completing the replacement and replenishment of cooling water, which is convenient to use.

[0028] A horizontal shell 121 is fixedly connected to the top of the inner wall of the housing 1. A lead screw 123 is rotatably connected to the inner wall of the horizontal shell 121 via a bearing 16. Both sides of the lead screw 123 are threaded with stroke blocks 124. Scrapers 125 are fixedly connected to the bottom ends of both stroke blocks 124 for cleaning. A reduction motor 122 is fixedly installed at one end of the housing 1 near the level switch 3, and the output end of the reduction motor 122 is fixedly connected to one end of the lead screw 123. A displacement port 13 is opened at the bottom end of the horizontal shell 121, and the two scrapers 125 are connected to… The inner wall of the displacement port 13 is slidably connected to provide movement space. The threads on both sides of the surface of the lead screw 123 are in opposite directions. The filtering mechanism 14 includes a collection box 141, a retainer 142, and a filter screen 143. One end of the collection box 141 is fixedly connected to the housing 1, and the other end of the collection box 141 is fixedly connected to the solenoid valve 9. The retainer 142 is fixedly connected to one side inside the collection box 141. The filter screen 143 is engaged with the inner wall of the retainer 142 to perform filtering. The top of the collection box 141 is fixedly installed with a box cover 15 by bolts, which can be disassembled.

[0029] In use, a scraping mechanism 12 is installed in the cooling water tank of the dust collection chamber. The reduction motor 122 can be started to drive the lead screw 123 to rotate. Since the two sides of the lead screw 123 have opposite thread directions, and under the guidance of the displacement port 13, the stroke blocks 124 and scraper 125 on both sides can move in opposite directions to scrape the scale and impurities at the bottom of the cooling water tank. The solenoid valve 9 is opened to allow the sewage to flow out from the outlet pipe 8. The filter screen 143 in the filtration mechanism 14 along the path can block the scale and impurities in the collection box 141. After the work is completed, the box cover 15 can be removed to clean the inside of the box and the filter screen 143.

The water pump 6 is electrically connected to an external power supply through the liquid level switch 3. The solenoid valve 9 is electrically connected to an external power supply through the temperature control switch 5 to control its opening and closing.

[0031] When in use, connect the external power supply, and set up the liquid level switch 3, temperature control switch 5, solenoid valve 9, and water pump 6 to automatically replace the cooling water in the water tank. When the liquid level in the water tank is too low, the liquid level switch 3 will control the indicator light 4 to light up, so that the staff can observe and take timely measures. The thermally conductive silicone pad 10 and heat dissipation fins 11 can improve the heat conduction efficiency and heat dissipation effect, which is conducive to cooling the water.

[0032] In practical use, the cooling water tank for the dust collection chamber of this multifunctional rotary kiln is connected to a herringbone pipe 2 at the end of the surface cooler. This pipe passes through the cooling water tank and connects to the dust collection chamber. A temperature control switch 5 (model KSD301) is installed inside the cooling water tank. When it detects that the water temperature in the tank is too high to support cooling, it controls the solenoid valve 9 to open, discharging water from the tank 1 through the outlet pipe 8. A level switch 3 (model BZ2401) detects that the water level in the tank is low and controls the water pump 6 to start, drawing external water into the tank, thus automatically completing the process. The replacement and replenishment of cooling water are convenient. A scraping mechanism 12 is installed in the cooling water tank of the dust collection chamber. The reduction motor 122 can be started to drive the lead screw 123 to rotate. Since the two sides of the lead screw 123 have opposite thread directions, and under the guidance of the displacement port 13, the stroke blocks 124 and scraper 125 on both sides can move in opposite directions to scrape the scale and impurities at the bottom of the cooling water tank. The solenoid valve 9 is opened to allow the sewage to flow out from the outlet pipe 8. The filter screen 143 in the filtration mechanism 14 along the path can block the scale and impurities in the collection box 141, thus making the cleaning of the cooling water tank of the dust collection chamber convenient.
