The filter screen 102 is located inside the first dust collector 1. A telescopic rod 104 is fixedly installed above the first dust collector 1, and the output end of the telescopic rod 104 is located inside the first dust collector 1. A cleaning brush 105 is fixedly installed at the output end of the telescopic rod 104, and the cleaning brush 105 is located on one side of the filter screen 102. An inspection door 106 is provided above the first dust collector 1, and the inspection door 106 is connected to the first dust collector 1. The exhaust gas treatment box 3 is located on one side of the second dust collector 2. The exhaust gas is initially treated by the first dust collector 1. The first dust collector 1 and the second dust collector 2 are connected by the first connecting pipe 101. The exhaust gas is further treated by the second dust collector 2. The exhaust gas treatment box 3 purifies and discharges the exhaust gas after the two treatments. The filter screen 102 filters the dust entering the second dust collector 2, leaving larger particles that can be recycled. The telescopic rod 104 can drive the cleaning brush 105 to rise and fall, thereby cleaning the filter screen 102 and preventing the filtered particles from adsorbing on the surface of the filter screen 102. Over time, this will affect the effect and efficiency of dust treatment. The inspection door 106 allows for convenient maintenance and replacement of the filter screen 102. The bolts 103 allow for quick installation and removal of the filter screen 102.
[0024] Please see Figures 2-3In this embodiment, an air inlet 401 is provided on one side of the first dust collector 1, and the air inlet 401 is connected to the first dust collector 1. A partition 402 is fixedly installed inside the first dust collector 1, and the air inlet 401 and the first connecting pipe 101 are located on both sides of the partition 402. By providing the air inlet 401, the exhaust gas and dust generated during the production of coated sand can be transported into the first dust collector 1. By providing the partition 402, the transported exhaust gas and dust can be blocked, so that it must bypass the partition 402 to pass through the first connecting pipe 101. The material is conveyed to the second dust collection cylinder 2, where recyclable large particles will be retained and fall down. The outer periphery of the first dust collection cylinder 1 is provided with an external thread 403, and an internal thread collection cylinder 404 is provided below the first dust collection cylinder 1. The internal thread collection cylinder 404 is threadedly connected to the first dust collection cylinder 1 through the external thread 403. By setting the internal thread collection cylinder 404, the recyclable large particles retained in the first dust collection cylinder 1 can be collected. By setting the external thread 403, the internal thread collection cylinder 404 can be easily disassembled and assembled, facilitating the recycling of the collected large particles.
[0025] Please see Figure 1 , Figure 4 and Figure 5In this embodiment, an installation block 501 is fixedly installed inside the second dust collector 2, and an installation pipe 502 is fixedly installed below the installation block 501. Multiple sets of atomizing nozzles 503 are arranged on both sides of the installation pipe 502. A water inlet 504 is provided on one side of the second dust collector 2, and the water inlet 504 is connected to the installation pipe 502. The installation pipe 502 is installed by setting the installation block 501, and an external water supply device can be connected to the installation pipe by setting the water inlet 504. 502 provides clean water, which is distributed to each atomizing nozzle 503 through the installation pipe 502. The water mist is sprayed out through the atomizing nozzle 503 to further adsorb and treat the exhaust gas dust. A second connecting pipe 506 is provided on one side of the second dust collector 2. The second connecting pipe 506 is located above the mounting block 501. The second dust collector 2 and the exhaust gas treatment box 3 are connected through the second connecting pipe 506. A drain port 505 is provided at the bottom of the second dust collector 2. The exhaust gas, after being adsorbed by water mist, can be transported to the exhaust gas treatment box 3. Wastewater containing adsorbed dust can be discharged from the second dust collector 2 via the drain port 505. A door 601 is provided on one side of the exhaust gas treatment box 3, rotatably connected to it. Two sets of support frames 602 are installed inside the exhaust gas treatment box 3, with a honeycomb activated carbon plate 603 positioned above them. The support frames 602 support and place the honeycomb activated carbon plate 603, which purifies the exhaust gas. The door 601 facilitates regular replacement of the honeycomb activated carbon plate to ensure purification quality. An exhaust pipe 604 is provided on one side of the exhaust gas treatment box 3, connected to it. An exhaust fan 605 is installed at one end of the exhaust pipe 604. The purified exhaust gas is discharged through the exhaust pipe 604, and the exhaust fan 605 provides suction for the overall exhaust gas transport.
[0026] During operation, the exhaust fan 605 provides suction to the entire device, and the exhaust gas discharge pipe of the coated sand is connected through the air inlet 401 to transport the exhaust gas and dust into the first dust collector 1. The baffle 402 separates the exhaust gas and dust, so that larger recyclable particles fall into the internal thread collection cylinder 404 and are collected under the action of gravity.
[0027] Then, the exhaust gas and dust are filtered by the filter screen 102 and transported to the second dust collector 2. The telescopic rod 104 can drive the cleaning brush 105 to rise and fall, so as to automatically clean the surface of the filter screen 102 and prevent a large amount of dust from adsorbing on the surface of the filter screen 102 after long-term operation, which would affect the treatment effect and efficiency of exhaust gas and dust.
[0028] Clean water is supplied to the installation pipe 502 through the water supply pipe and sprayed out in the form of water mist through the atomizing nozzle 503 to further adsorb the exhaust gas dust. The wastewater with adsorbed dust can be discharged through the drain outlet 505. The exhaust gas after adsorption is transported to the exhaust gas treatment box 3 through the second connecting pipe 506.
[0029] Two sets of honeycomb activated carbon plates are placed on the support frame 602 to purify the exhaust gas, which is then discharged through the exhaust pipe 604. The honeycomb activated carbon plates 603 inside the exhaust gas treatment box 3 can be easily replaced periodically through the box door 601 to ensure the purification effect.
[0030] Through the above steps, the flue gas conveyed to the second dust collector 2 is filtered by the filter screen 102, retaining large particles that can be recycled. The cleaning brush 105 can be pushed by the telescopic rod 104 to clean the surface of the filter screen 102, preventing the filter screen 102 from accumulating a large number of particles and affecting its operation after long-term use. The filter screen 102 can be easily disassembled by bolts 103 through the inspection door 106, so as to maintain and replace the filter screen 102. This solves the problem that the filter screen 102 of the current membrane sand flue gas dust treatment device will accumulate a large amount of flue gas dust during long-term use, causing blockage, and is inconvenient to maintain and clean, which easily affects the effect and efficiency of dust treatment.
[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
