[0030] Please combine Figures 1 to 4As shown, the utility model provides a m-nitroacetophenone mother liquor collecting device, which comprises a first box body 1 and a second box body 2 fixedly mounted on the bottom end of the first box body 1, the first box body 1 is connected to the inside of the second box body 2, a pair of cover plates 3 are rotatably mounted on the top of the first box body 1, a mother liquor inlet 4 is fixedly mounted on the top of the first box body 1, a mother liquor outlet 5 is fixedly mounted at one end in the length direction of the second box body 2, a thread can be arranged on the outer surface of the mother liquor inlet 4, the mother liquor inlet 4 is connected to the m-nitroacetophenone mother liquor production device, and the produced m-nitroacetophenone mother liquor The liquid enters the interior of the first box 1 through the mother liquid inlet 4 to collect the m-nitroacetophenone mother liquid. The interior of the first box 1 is provided with a filter plate 6 which can be raised and lowered. The m-nitroacetophenone mother liquid entering the first box 1 is initially filtered by the filter plate 6 to filter out large particles of impurities in the m-nitroacetophenone mother liquid. When a certain amount of impurities accumulate on the upper surface of the filter plate 6, the height of the filter plate 6 can be raised to separate the filter plate 6 from the interior of the first box 1. At this time, the impurities accumulated on the surface of the filter plate 6 can be removed, and at the same time, it can be prevented that the impurities block the filter holes on the filter plate 6 and affect the flow. The filtration efficiency is improved, and the m-nitroacetophenone mother liquor passing through the filter plate 6 enters the interior of the second box 2. The m-nitroacetophenone mother liquor is allowed to settle in the interior of the second box 2, further reducing the impurities in the m-nitroacetophenone mother liquor and improving the quality of the m-nitroacetophenone mother liquor. Finally, the treated m-nitroacetophenone mother liquor is discharged from the mother liquor outlet 5. A push plate 8 is slidably provided inside the second box 2, and a filter part 9 is provided on the push plate 8. The filter part 9 is spaced a certain distance from the inner bottom surface of the second box 2 to prevent more impurities from accumulating on the inner bottom surface of the second box 2 and affecting the m-nitroacetophenone mother liquor passing through. The speed of the filter section 9 is controlled. An impurity outlet is provided on the other end of the second housing 2, and a sealing plate 11 is provided at the impurity outlet. A second threaded rod 10 is rotatably installed on the inner surface of the second housing 2. One end of the second threaded rod 10 passes through the interior of the push plate 8 and is threadedly connected with the push plate 8. Impurities generated by the precipitation of the m-nitroacetophenone mother liquor will accumulate on the inner bottom surface of the second housing 2. When cleaning this part of impurities, the impurity outlet is opened, and then the second threaded rod 10 is rotated to make the push plate 8 close to the impurity outlet, so that the impurities are pushed to the impurity outlet, so that the impurities inside the second housing 2 can be quickly removed, and the cleaning difficulty is small.

[0031] Furthermore, a fixing frame is fixedly installed on the inner surface of the first box body 1, and a first threaded rod 7 is rotatably installed on the fixing frame. One end of the first threaded rod 7 passes through the interior of the filter plate 6 and is threadedly connected to the filter plate 6. A limiting slide rod 14 is fixedly installed on the fixing frame. One end of the limiting slide rod 14 passes through the interior of the filter plate 6 and is slidably connected to the filter plate 6.

[0032] Furthermore, the filter plate 6 is arranged to be concave, and the impurities blocked by the filter plate 6 will slide to the bottom end of the filter plate 6, so that the impurities are mainly accumulated on the inner bottom surface of the filter plate 6, and the impurities will not completely cover the filter plate 6 to affect the filtration efficiency of the m-nitroacetophenone mother liquor; a horizontal filter plate 12 is fixedly arranged on the bottom end of the filter plate 6, and the horizontal filter plate 12 is fixedly connected to the filter plate 6 through the vertical filter plate 13, and the horizontal filter plate 12 and the vertical filter plate 13 form an impurity outlet channel. When the height of the filter plate 6 is raised to separate the filter plate 6 from the inside of the first box body 1, the impurities accumulated on the filter plate 6 can be discharged through the impurity outlet channel, and the vertical filter plate 13 is in a vertical state, so that the surface of the vertical filter plate 13 will not be easily blocked by impurities, and the vertical filter plate 13 can increase the filtration speed of the filter plate 6.

[0033] Furthermore, a bolt 15 is rotatably installed on the outer surface of the second box body 2, and convex plates are fixedly installed on both ends of the sealing plate 11 in the length direction. One end of the bolt 15 passes through the interior of one of the convex plates and is threadedly connected to the convex plate. A limiting rod 16 is fixedly installed on the outer surface of the second box body 2, and one end of the limiting rod 16 passes through the interior of another convex plate and is slidably connected to the convex plate. Rotating the bolt 15 can make the sealing plate 11 open or close the outlet.
