CONCRETE IMPLEMENTING METHOD
[0019] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.
[0020] Referring to Figures 1-3 The material inlet and outlet sealing assembly of the diamond micro-powder air flow classifier comprises two groups of pipes 1, one end of each group of pipes 1 is fixedly connected with a flange plate one 2 and a flange plate two 3, the flange plate one 2 and the flange plate two 3 are connected through a plurality of screws 5, a plurality of fixed grooves 4 are formed on the outer walls of the flange plate one 2 and the flange plate two 3, each pair of fixed grooves 4 is formed by two fixed grooves 4, each pair of fixed grooves 4 is arranged in position correspondence, and the shapes and sizes of the slot openings of the fixed grooves 4 are matched with each other, a fixed clamping block 7 is clamped at each pair of fixed grooves 4, the end of the screw 5 at each pair of fixed clamping blocks 7 is fixedly connected with a fixed block 9, a clamping groove one 10 and a clamping groove two 11 are respectively formed on the outer walls of the fixed block 9 and the screw 5 nut, and the clamping groove one 10 and the clamping groove two 11 are both circular, and a clamping block 15 is formed in the clamping groove one 10 and the clamping groove two 11, and the fixed clamping block 7 is connected with the two clamping blocks 15 through a connecting mechanism.
[0021] Further, through the clamping of the fixed clamping block 7 and the fixed groove 4, and the bidirectional locking of the screw 5 through the connecting mechanism, multiple reinforcement of the connection between the flange plate one 2 and the flange plate two 3 is formed, and the loosening of the screw 5 caused by vibration is effectively inhibited; it should be noted that the pipe 1 can be used as a feeding pipe or a discharging pipe of the air flow classifier, and the other pipe 1 can be used as a connecting pipe, and a sealing gasket is arranged between the flange plate one 2 and the flange plate two 3 to form a sealed closure of the material to prevent leakage from the flange connection.
[0022] The connecting mechanism comprises a side plate 8 fixedly connected to the outer walls on both sides of the fixed clamping block 7, and a sliding rod 12 is slidingly connected to the outer wall of the side plate 8, and the end of the sliding rod 12 is fixedly connected with the clamping block 15.
[0023] Further, the sliding connection of the side plate 8 and the sliding rod 12 allows the clamping block 15 to be self-adaptive to the position deviation of the clamping groove during installation, thereby reducing the assembly difficulty; at the same time, under the vibration working condition, the sliding of the sliding rod 12 can buffer part of the impact force, thereby avoiding the risk of breakage of the clamping block 15 caused by rigid connection.
[0024] The end of the sliding rod 12 away from the clamping block 15 is fixedly connected with a limiting block 13, the radius size of the limiting block 13 is greater than the radius size of the sliding rod 12, a spring 14 is sleeved on the outer wall of the sliding rod 12, one end of the spring 14 is fixedly connected with the end face of the side plate 8, and the other end of the spring 14 is fixedly connected with the lower end face of the limiting block 13.
[0025] Further, the elastic force of the spring 14 can continuously pre-tighten the sliding rod 12, so that the clamping block 15 is always tightly attached to the inner wall of the clamping groove, and the micro gap caused by vibration is eliminated.
[0026] Each pair of fixed groove 4 end face is fixedly connected with positioning rod 6, fixed clamping block 7 is inserted in the outer wall of positioning rod 6, the outer wall of fixed clamping block 7 is U-shaped, the outer wall of vertical section of fixed clamping block 7 is in the same horizontal plane with the outer wall of flange plate one 2 and flange plate two 3, the inner wall of fixed clamping block 7 is in contact with the inner wall of fixed groove 4;
[0027] Further, the insertion and cooperation of positioning rod 6 and U-shaped fixed clamping block 7 ensure the accurate alignment of fixed clamping block 7 during installation, avoiding the matching failure of clamping block 15 and clamping groove due to misalignment.
[0028] In the utility model, when the device is used, the operator preliminarily connects flange plate one 2 and flange plate two 3 through a plurality of screws 5, at this time, the screw 5 on one side of the fixed groove 4 is installed subsequently, then the fixed clamping block 7 is inserted into the corresponding fixed groove 4 along the positioning rod 6. At this time, the side plates 8 on both sides of the fixed clamping block 7 are connected with the clamping block 15 through the sliding rod 12, then the sliding rod 12 is pressed downward, driving the clamping block 15 to slide downward, at this time, the screw 5 on one side of the fixed groove 4 is installed in the specified position, and the clamping block 15 at the end of the sliding rod 12 is automatically embedded into the clamping groove one 10 of the end block 9 of the screw 5 and the clamping groove two 11 at the bottom of the screw cap of the screw 5 under the pre-tightening force of the spring 14. Since the clamping groove one 10 and the clamping groove two 11 are both circularly arranged, the clamping block 15 can adapt to the possible slight positional deviation of the screw 5 during installation through the sliding of the sliding rod 12, and the elastic deformation of the spring 14 allows the clamping block 15 to produce a slight displacement under the vibration condition, buffers the impact force, and avoids the rupture of the clamping block 15 due to rigid contact.
[0029] When the airflow classifier is working, the vibration generated by the equipment is transmitted to the flange plate connection. At this time, the fixed clamping block 7 is tightly clamped with the fixed groove 4 through its U-shaped structure, forming a transverse constraint on the connecting surface of the flange plate one 2 and the flange plate two 3, and inhibiting the relative displacement of the flange plate; and the clamping block 15 forms a longitudinal constraint on the clamping groove one 10 and the clamping groove two 11 of the screw 5, further preventing the axial loosening of the screw 5 due to vibration. In addition, the continuous pre-tightening force of the spring 14 can eliminate the gap between the clamping block 15 and the clamping groove, ensure the stability of the locking, and form a multiple reinforcement effect.
[0030] When disassembly or maintenance is needed, the operator pulls out the limiting block 13, compresses the spring 14 and drives the sliding rod 12 and the clamping block 15 to separate from the clamping groove one 10 and the clamping groove two 11, then pulls out the fixed clamping block 7, and the screw 5 can be loosened. The whole operation process does not need complex tools and is convenient to maintain.
