[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] like Figures 1-6 As shown, a dust wastewater treatment device for the green production of ready-mixed concrete includes a treatment box 1, a slot 2 is provided in the center of one side of the treatment box 1, a filter frame 3 is provided inside the slot 2, and an ash leakage groove 10 is provided at the rear of the upper and lower ends of the filter frame 3, a box cover 6 is provided on the top of the treatment box 1, and the bottom of the box cover 6 is movably connected to the impeller 11 through a bearing, and a scraper 12 is fixedly installed at the bottom of the blade of the impeller 11, a coarse filtering mechanism 8 is installed at the front end of one side of the treatment box 1, and an ash collecting box 13 is movably installed at the lower end through the rear end of the treatment box 1, and the ash collecting box 13 is located at the bottom of the ash leakage groove 10, and a water inlet pipe 7 is fixedly installed at the front of the top of the box cover 6.

[0030] Specifically, when treating dust wastewater, the wastewater is injected into the treatment box 1 through the water inlet pipe 7, the wastewater is filtered through the filter frame 3, and the solids in the wastewater are intercepted by the filter frame 3. Then, the coarse filtration mechanism 8 is started, and the wind pressure generated by the coarse filtration mechanism 8 drives the impeller 11 to rotate. While the impeller 11 rotates, the scraper 12 is used to clean the top surface of the filter frame 3, and the solids intercepted by the filter frame 3 are pushed to the ash leakage groove 10, and fall into the ash collecting box 13 through the ash leakage groove 10 to be collected, which can avoid the filter frame 3 from being blocked during use. While treating the dust wastewater, the filter frame 3 can be cleaned without taking out the filter frame 3, thereby improving the treatment efficiency of the dust wastewater.

[0031] A water pump 5 is fixedly installed through the front end of the treatment box 1, and the water outlet of the water pump 5 is fixedly connected to the spray plate 14 through a pipe. A through hole 16 is opened in the center of the upper and lower ends of the spray plate 14, and a water inlet pipe 7 is fixedly installed in the front of the upper and lower ends of the box cover 6. The diameter of the through hole 16 is twice the inner diameter of the water inlet pipe 7. The through hole 16 is located directly below the water inlet pipe 7, and the spray plate 14 is located above the filter frame 3.

[0032] Specifically, after the wastewater is injected into the treatment box 1 through the water inlet pipe 7, it passes through the through hole 16 and falls on the filter frame 3 to be filtered. After the water pump 5 is started, the filtered wastewater is extracted and sprayed out through the spray plate 14. The dust emission pipe is connected through the coarse filter mechanism 8, and the coarse filter mechanism 8 is used to intercept large particles of solid in the dust, while the fine dust enters the treatment box 1, encounters the wastewater sprayed by the spray plate 14, and follows the wastewater to fall on the filter frame 3, which can prevent the fine dust from spreading upward in the treatment box 1 and being sprayed out from the water inlet pipe 7 to cause secondary pollution.

[0033] An isolation member 15 is fixedly installed inside the treatment box 1 , and the top view of the isolation member 15 is in a “V” shape. The isolation member 15 is located at the bottom of the filter frame 3 .

[0034] Specifically, by setting up the isolation piece 15 to divide the space inside the treatment box 1, it is convenient to isolate the ash box 13 and seal the interior of the treatment box 1 to prevent wastewater from contacting the ash box 13 and causing corrosion to it, thereby preventing wastewater from leaking.

[0035] The coarse filtering mechanism 8 includes a fan 801 , a filter cartridge 802 is provided at the front end of the fan 801 , an ash box 803 is provided through the bottom of the filter cartridge 802 , and a coarse filter screen frame 804 is provided inside the filter cartridge 802 .

[0036] The filter cartridge 802 is threadedly connected to the air inlet of the fan 801, and the coarse filter frame 804 is sleeved on the filter cartridge 802. The coarse filter frame 804 is located at the top and rear position of the ash box 803. An air inlet pipe is fixedly installed in the front of one side of the treatment box 1, and the air outlet of the fan 801 is fixedly connected to the air inlet pipe, and the air inlet pipe and the impeller 11 are at the same height.

[0037] Specifically, after the fan 801 is started, the dust discharged from the dust pipe is drawn into the filter cartridge 802, and the large particles of solid in the dust are intercepted by the coarse filter frame 804, while the fine dust passes through the fan 801 and enters the treatment box 1, and the intercepted large particles of solid fall into the ash box 803, preventing large particles of solid from accumulating in the filter cartridge 802 and causing blockage, which affects the fluidity of the fan 801.

[0038] The bottom of the fan 801 and the ash box 803 are provided with the same base 9, and a drainage pipe 4 is fixedly installed on one side of the treatment box 1 near the bottom.

[0039] Specifically, the base 9 is provided to facilitate support of the coarse filtering mechanism 8, and the drain pipe 4 is provided at the same time, so that the wastewater in the treatment box 1 can be discharged after the dust and wastewater treatment is completed.

[0040] It should be noted that the present invention is a dust wastewater treatment device for green production of ready-mixed concrete. When in use, first, when treating dust wastewater, wastewater is injected into the treatment box 1 through the water inlet pipe 7. The wastewater passes through the through hole 16 and falls on the filter frame 3 to be filtered. The filter frame 3 is used to intercept solids in the wastewater.

[0041] Then, the water pump 5 and the fan 801 in the coarse filter mechanism 8 are started. After the water pump 5 is started, the filtered wastewater is extracted and sprayed out through the spray disc 14. The coarse filter mechanism 8 is connected to the dust discharge pipe, and the coarse filter mechanism 8 is used to intercept large particles of solid in the dust, while the fine dust enters the treatment box 1. After encountering the wastewater sprayed by the spray disc 14, it follows the wastewater and falls on the filter frame 3, which can prevent the fine dust from spreading upward in the treatment box 1 and being sprayed out from the water inlet pipe 7 to cause secondary pollution.

[0042] After the fan 801 is started, the dust discharged from the dust pipe is sucked into the filter cartridge 802, and the large solid particles in the dust are intercepted by the coarse filter frame 804, while the fine dust passes through the fan 801 and enters the treatment box 1. The intercepted large solid particles fall into the ash box 803;

[0043] The wind pressure generated by the fan 801 drives the impeller 11 to rotate. While the impeller 11 is rotating, the scraper 12 is used to clean the top surface of the filter frame 3, and the solid matter intercepted by the filter frame 3 is pushed to the ash leakage groove 10, and falls into the ash collecting box 13 through the ash leakage groove 10 to be collected, which can prevent the filter frame 3 from being blocked during use. While treating dust wastewater, the filter frame 3 can be cleaned without removing the filter frame 3, thereby improving the treatment efficiency of dust wastewater. After completing the treatment of dust and wastewater, the wastewater remaining in the treatment box 1 is discharged through the drain pipe 4.
