[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] Such as Figure 1 、 Figure 2As shown in the figure, the utility model provides a wastewater pretreatment device for a desizing, scouring and bleaching combined machine, which includes a screening box 1. Above the screening box 1, there is a lifting top box 2. The top of the lifting top box 2 is fixedly connected through penetration with a crushing tank 3. The right side of the crushing tank 3 is fixedly connected with a water inlet pipe 4. On both the front and rear sides of the screening box 1, two extension plates 11 are fixedly installed. On the tops of the two extension plates 11 on the front and rear sides, electric push rods 12 are fixedly installed. On both the front and rear sides of the lifting top box 2, fixed side plates 21 are fixedly installed. The tops of the two electric push rods 12 on the front side and the two electric push rods 12 on the rear side are respectively fixedly connected with the bottoms of the two fixed side plates 21. On both the front and rear inner walls of the screening box 1, limiting plates 17 are fixedly installed. Above the two limiting plates 17, a filtering mechanism 16 is arranged. At the bottom of the screening box 1, four support legs 13 are fixedly installed in a rectangular array. At the center of the bottom of the screening box 1, an L-shaped drain pipe 14 is fixedly connected. On the outer wall of the horizontal part of the L-shaped drain pipe 14, an electric control valve 15 is fixedly installed. At the eccentric position of the bottom of the lifting top box 2, a square clamping ring 22 is fixedly installed. On the top of the screening box 1, a square sealing groove 18 is opened. After the lifting top box 2 and the screening box 1 are combined, the square clamping ring 22 is clamped with the square sealing groove 18;
[0023] By starting the two electric push rods 12 on each of the front and rear sides of the screening box 1, the overall lifting top box 2 and the crushing tank 3 can be lifted upward by using the connection between the output ends of the electric push rods 12 and the bottoms of the two fixed side plates 21 on the front and rear sides of the lifting top box 2, so that the top of the screening box 1 is completely exposed, which is convenient for taking out the filtering mechanism 16 for cleaning. And the filtered wastewater can be directly discharged through the L-shaped drain pipe 14, and the discharge time can be controlled through the electric control valve 15. After cleaning the filtering mechanism 16, starting the electric push rods 12 again can combine the lifting top box 2 and the screening box 1, and the clamping between the square clamping ring 22 at the bottom of the lifting top box 2 and the square sealing groove 18 at the top of the screening box 1 can improve the sealing performance after combination and prevent water leakage.
[0024] As Figure 3 shown, the filtering mechanism 16 includes a first diversion funnel 161. At the lowest part of the inner circle of the first diversion funnel 161, a filter screen 162 is fixedly installed. On the upper parts of the front and rear inner walls of the first diversion funnel 161, lifting handles 163 are fixedly installed. On both the front and rear sides of the screening box 1, docking plates 164 are fixedly installed. On the left and right sides of the bottoms of the two docking plates 164, slots 165 are opened. On the left and right sides of the tops of the two limiting plates 17, inserting rods 171 are fixedly installed. The two inserting rods 171 on the tops of the two limiting plates 17 on the front and rear sides are respectively clamped with the two slots 165 opened at the bottoms of the two docking plates 164.
[0025] When cleaning the filter screen 162, after the wastewater is drained, just start two electric push rods 12 on each of the front and rear sides of the screening box 1. Then, using the connection between the output ends of the electric push rods 12 and the bottoms of the front and rear fixed side plates 21 of the lifting top box 2, the entire lifting top box 2 and the crushing tank 3 can be lifted upward, completely exposing the top of the screening box 1. Then, hold the two lifting handles 163 inside the first diversion funnel 161 and lift the first diversion funnel 161 upward to remove the first diversion funnel 161 and clean the filter screen 162. After cleaning, the rotating rod 34 can be reinstalled as selected. At the same time, lift the first diversion funnel 161 using the lifting handles 163 and align it with the top of the screening box 1 and place it in. Align the slot 165 at the bottom of the docking plate 164 with the insertion rod 171 at the top of the limit plate 17 and snap it in to complete the fixation.
[0026] As Figure 4 , Figure 5 As shown in the figure, a second diversion funnel 23 is fixedly installed on the inner ring of the lifting top box 2. A motor 31 is fixedly installed on the top of the crushing tank 3. The output shaft of the motor 31 penetrates into the inner cavity of the crushing tank 3 and is fixedly installed with a driving rod 32. A plurality of crushing blades 33 are evenly fixedly installed on the outer wall of the driving rod 32. A plurality of crushing blades 33 are all located in the inner cavity of the crushing tank 3. A rotating rod 34 is arranged below the driving rod 32. The bottom of the rotating rod 34 extends below the lifting top box 2 and is located inside the first diversion funnel 161. A threaded rod 321 is fixedly installed at the bottom of the driving rod 32. A threaded groove 341 is opened at the top of the rotating rod 34. The threaded rod 321 is threadedly connected with the threaded groove 341. A plurality of stirring rods 342 arranged up and down are fixedly installed on the left and right sides of the outer wall of the rotating rod 34;
[0027] The wastewater of the desizing, scouring and bleaching combined machine can be directly discharged into the crushing tank 3 through the connecting water inlet pipe 4. When discharging, by starting the motor 31, the driving rod 32 and a plurality of crushing blades 33 on the outer wall of the driving rod 32 can be driven to rotate at high speed in the inner cavity of the crushing tank 3 to crush larger particulate matters and other impurities in the wastewater. Then, it flows into the first diversion funnel 161 at the top of the screening box 1 through the second diversion funnel 23 in the lifting top box 2 and is filtered by the filter screen 162 for cotton floc debris, and pre-treatment is carried out in advance. The rotating rod 34 can be threadedly installed on the outer wall of the threaded rod 321 by using the threaded groove 341 with reverse thread design to dock with the driving rod 32, and it will only become tighter and tighter during the rotation of the driving rod 32. Cooperating with the stirring rods 342 to stir the wastewater, the debris is evenly mixed in the wastewater to avoid rapid blockage of the filter screen 162 caused by precipitation, thereby reducing the cleaning frequency of the filter screen 162. At the same time, the suspended lifting top box 2 can also rotate and remove the rotating rod 34 for cleaning. After cleaning, the rotating rod 34 can be reinstalled as selected.
[0028] Next, specifically describe the working principle of the wastewater pretreatment device of the desizing, scouring and bleaching combined machine.
[0029] AsFigures 1 - 5 As shown, the wastewater of the desizing, scouring and bleaching combined machine can be directly discharged into the crushing tank 3 through the connecting water inlet pipe 4. When discharging, starting the motor 31 can drive the driving rod 32 and several crushing blades 33 on the outer wall of the driving rod 32 to rotate at high speed in the inner cavity of the crushing tank 3, crushing larger particulate matters and other impurities in the wastewater. Then, it flows into the diversion funnel 161 at the top of the screening box 1 through the diversion funnel 23 in the lifting top box 2, and the cotton floc debris is filtered through the filter screen 162 for pre-treatment in advance. After a large amount of wastewater with reduced cotton floc particulate matters passes through the L-shaped drain pipe 14, the electric control valve 15 can be opened at any time for discharging, reducing the time required for subsequent precipitation and improving the purification efficiency. At the same time, the rotating rod 34 can be threadedly installed on the outer wall of the threaded rod 321 by using the reverse-threaded threaded groove 341, so that it is butted against the driving rod 32 and will only become tighter and tighter during the rotation of the driving rod 32. Cooperating with the stirring rod 342 to stir the wastewater, the debris is evenly mixed in the wastewater, avoiding rapid blockage of the filter screen 162 caused by precipitation, thereby reducing the cleaning times of the filter screen 162. When cleaning the filter screen 162, after the wastewater is emptied, only need to start two electric push rods 12 on each of the front and rear sides of the screening box 1, and the overall lifting top box 2 and the crushing tank 3 can be lifted by using the connection between the output end of the electric push rod 12 and the bottom of the two fixed side plates 21 at the front and rear of the lifting top box 2, so that the top of the screening box 1 is completely exposed. Then, hold the two lifting handles 163 inside the diversion funnel 161 and lift the diversion funnel 161 upward to remove the diversion funnel 161 and clean the filter screen 162. At the same time, the suspended lifting top box 2 can also rotate and remove the rotating rod 34 for cleaning. After cleaning, the rotating rod 34 can be reinstalled, and at the same time, lift the diversion funnel 161 by using the lifting handle 163 and align it with the top of the screening box 1 and put it in, so that the slot 165 at the bottom of the docking plate 164 is aligned with the insertion rod 171 at the top of the limiting plate 17 and snapped in for fixation. Then, the electric push rod 12 can be started again to merge the lifting top box 2 and the screening box 1, and the sealing performance after merging can be improved by the clamping between the square clamping ring 22 at the bottom of the lifting top box 2 and the square sealing groove 18 at the top of the screening box 1 to prevent water leakage.
[0030] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit and idea of the present invention are all within the protection scope of the present invention.
