[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0021] The pipe flange connector 3 (model 25PVC), the arc-shaped rubber strip 10 (model da-00001) and the fixing bolt 12 (model M26) mentioned in the present utility model can all be obtained by purchasing from the market or customizing privately.
[0022] Please refer to Figures 1 to 3 , an embodiment provided by the present utility model: a chemical pump anti-drip structure, including a chemical pump flange connector 1, a pipe flange connector 3 is provided on one side of the chemical pump flange connector 1, and an arc-shaped clamping plate 5 is provided on each of the front and rear sides of the pipe flange connector 3. A flange clamping groove 11 is provided on the surface of the arc-shaped clamping plate 5 facing the pipe flange connector 3;
[0023] On one side of the flange clamping groove 11, an arc-shaped groove 9 located on the outer surface of the arc-shaped clamping plate 5 is provided, and an arc-shaped rubber strip 10 is provided inside the arc-shaped groove 9;
[0024] The outer surface of the arc-shaped clamping plate 5 is provided with a plurality of bolt fixing through-holes A6 arranged in an arc shape. One side of the bolt fixing through-hole A6 is provided with a fixing bolt 12, and the other side of the bolt fixing through-hole A6 is provided with a fixing nut 13. One side of the fixing nut 13 is provided with a nut clamping sleeve 14. One side of the outer surface of the nut clamping sleeve 14 is provided with a bolt fixing through-hole A6 whose shape is the same as that of the fixing nut 13. One side of the outer surface of the nut clamping sleeve 14 is fixedly provided with an arc-shaped locking plate 15, and the radian of the arc-shaped locking plate 15 is the same as the radian of the outer surface of the arc-shaped clamping plate 5.
[0025] The surface of the chemical pump flange connector 1 facing the pipe flange connector 3 is provided with a square positioning groove 2. The surface of the pipe flange connector 3 facing the chemical pump flange connector 1 is provided with a square positioning plate 4, and the shape of the inner wall of the pipe flange connector 3 matches the shape of the outer surface of the square positioning plate 4. The outer surface of the chemical pump flange connector 1 is provided with a plurality of bolt fixing through-holes B7, and the outer surface of the pipe flange connector 3 is provided with a plurality of bolt fixing through-holes C8. The positions of the bolt fixing through-holes B7 and the bolt fixing through-holes C8 correspond to the positions of the bolt fixing through-holes A6 on the outer surface of the arc-shaped clamping plate 5. When it is necessary to connect the chemical pump flange connector 1 and the pipe flange connector 3, first align the square positioning plate 4 on the outer surface of the pipe flange connector 3 with the square positioning groove 2 on the outer surface of the chemical pump flange connector 1, and then combine the chemical pump flange connector 1 and the pipe flange connector 3. Through the positioning of the square positioning plate 4 and the square positioning groove 2, the bolt fixing through-hole B7 on the outer surface of the chemical pump flange connector 1 can be accurately aligned with the bolt fixing through-hole C8 on the outer surface of the pipe flange connector 3, and the rotation of the pipe flange connector 3 can be prevented, so as to facilitate the subsequent operation.
[0026] The shape of the inner wall of the two combined flange clamping grooves 11 matches the shape of the outer surface of the chemical pump flange connector 1, and the width of the inner wall of the flange clamping groove 11 is the same as the value of the combined width of the chemical pump flange connector 1 and the pipe flange connector 3. When the chemical pump flange connector 1 and the pipe flange connector 3 are combined, the arc-shaped clamping plate 5 is simultaneously clamped on the combined chemical pump flange connector 1 and pipe flange connector 3 through the flange clamping groove 11 on the arc-shaped clamping plate 5. Since the value of the combined width of the chemical pump flange connector 1 and the pipe flange connector 3 is the same as the value of the width of the inner wall of the flange clamping groove 11, the arc-shaped clamping plate 5 can prevent a gap from being generated between the combined chemical pump flange connector 1 and the pipe flange connector 3, thereby preventing the leakage of corrosive media or special liquids during transportation. Through the above technical solutions, the safety of the equipment is improved.
[0027] After the arc-shaped clamping plate 5 is clamped in the chemical pump flange connector 1 and the pipeline flange connector 3, the orientation of the two arc-shaped clamping plates 5 is adjusted to adjust the bolt fixing port A6 located on the outer surface of the arc-shaped clamping plate 5 to a position corresponding to the bolt fixing port B7 and the bolt fixing port C8, and then the chemical pump flange connector 1, the pipeline flange connector 3 and the arc-shaped clamping plate 5 are fixed by the fixing bolts 12 and the fixing nuts 13. When the fixing is completed, the hexagonal through hole 16 located on the outer surface of the nut clamping sleeve 14 is aligned with the fixing nut 13 and put on. In the process of putting the nut clamping sleeve 14 on the outside of the fixing nut 13, the arc-shaped locking plate 15 fixed on the outer surface of the nut clamping sleeve 14 will also cover the outer surface of the arc-shaped clamping plate 5.
[0028] A screw fixing opening is provided on both sides of the outer surface of the arc-shaped locking plate 15, and the position of the screw fixing opening corresponds to the position of the arc-shaped rubber strip 10; when the nut clamping sleeve 14 is completely fitted with the arc-shaped clamping plate 5, the arc-shaped locking plate 15 and the arc-shaped rubber strip 10 are fixed by screws. When the arc-shaped locking plate 15 is fixed, the nut clamping sleeve 14 fixed thereto and the fixing nut 13 located inside the hexagonal through hole 16 on the outer surface of the nut clamping sleeve 14 will be locked accordingly and cannot rotate. By locking the fixing nut 13 and making it unable to rotate, it can prevent the fixing nut 13 from rotating without authorization as the use time increases, thereby causing the flange fixation to loosen.
[0029] The upper and lower end surfaces of the arc-shaped rubber strip 10 are fixed to the inner wall of the arc-shaped groove 9 by screws, and the outer surface of the arc-shaped rubber strip 10 is in contact with the inner wall of the arc-shaped groove 9; when the chemical pump flange connector 1 and the pipeline flange connector 3 need to be disassembled, the arc-shaped locking plate 15 needs to be removed first, and the fixing nut 13 needs to be removed from the fixing bolt 12 to release the fixation between the chemical pump flange connector 1, the pipeline flange connector 3 and the arc-shaped clamping plate 5. When the fixation between the chemical pump flange connector 1, the pipeline flange connector 3 and the arc-shaped clamping plate 5 is released, the arc-shaped clamping plate 5 can be removed to separate the chemical pump flange connector 1 and the pipeline flange connector 3. When the chemical pump needs to be reassembled, When the flange connector 1 and the pipe flange connector 3 are connected, the above operations can be repeated. However, when the nut clamping sleeve 14 is put on, it is necessary to first remove the screws fixing the arc rubber strip 10, take the arc rubber strip 10 out from the inside of the arc groove 9, and install a new arc rubber strip 10 inside the arc groove 9. This is because during the first fixing operation, multiple screw fixing openings are drilled on the outer surface of the arc rubber strip 10 by multiple screws fixing the arc locking plate 15. During the second fixing operation, the screw fixing openings on the arc locking plate 15 may be aligned with the screw fixing openings drilled on the outer surface of the arc rubber strip 10 during the first fixing operation, thereby affecting its fixing strength.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
