Technical Field

[0001] The invention relates to the field of NdFeB production, and in particular to equipment for NdFeB production. Background Art

[0002] During the processing of NdFeB waste, a certain amount of sewage will be generated. If this sewage is discharged directly, it will have a great impact on the ecological environment, so it is necessary to carry out sewage treatment operations. During the sewage treatment process, in order to ensure that the treated sewage does not contain harmful substances, it is necessary to monitor it in real time. Then it is necessary to sample the treated sewage and then test the samples to determine whether it meets the discharge standards. Since sewage is generally discharged through sewer pipes and there is a certain pressure when wastewater is discharged, high-pressure wastewater will be sprayed onto the staff when sampling. In addition, the wastewater may be mixed with corrosive substances, causing corrosion to clothing and skin.

[0022] The corresponding ends of the upper clamp 3 and the lower clamp 4 are fastened and fixed by bolts. The lower clamp 4 is composed of an arc rod 41 located on both sides of the vertical pipe 6. Two groups of protrusions 42 are arranged in parallel on both side walls of the vertical pipe 6 below the sewage pipe 1. One end of the arc rod 41 is located between the corresponding two groups of protrusions 42. The end of the arc rod 41 is provided with a rotating shaft 43 that passes through the side wall of the corresponding protrusion 42.

[0023] A circular block 13 located outside the top of the vertical pipe 6 is provided at the top of the stud 8, and a driving block 14 located below the vertical pipe 6 is provided at the bottom of the stud 8. The diameters of the circular block 13 and the driving block 14 are both larger than the inner diameter of the vertical pipe 6, and the diameter of the circular block 13 is smaller than the diameter of the vertical pipe 6. The top of the circulation channel 9 is connected to the outer space of the stud 8, and the circulation channel 9 is located below the circular block 13. The distance between the circulation channel 9 and the inner bottom wall of the sewage pipe 1 is smaller than the distance between the bottom end of the vertical pipe 6 and the driving block 14.

[0024] The buffer mechanism 12 includes a sliding channel 121 arranged in the stud 8 below the buffer cavity 10, the sliding channel 121 is connected to the buffer cavity 10 through a connecting port, a sliding rod 122 is arranged in the connecting port, a sliding block 123 located in the sliding channel 121 is arranged at the bottom end of the sliding rod 122, a spring 124 is arranged on the sliding rod 122 above the sliding block 123, a conical buffer seat 125 located in the buffer cavity 10 and adapted thereto is arranged at the top of the sliding rod 122, a limit block 126 is arranged on the side wall of the upper half of the buffer cavity 10, and the limit block 126 is abutted against the top inclined wall of the buffer seat 125, and the installation position of the limit block 126 is opposite to the position of the drain outlet 11.

[0025] A pressure relief valve 15 is provided on the top of the side wall of the pressure relief box 7, and a grid plate 16 fixedly connected to the corresponding inner wall is also provided inside the pressure relief box 7. A plurality of groups of baffles 17 are suspended in the pressure relief box 7 on both sides of the grid plate 16. The top of the baffle plate 17 is hingedly fixed to the inner top wall of the pressure relief box 7 by a hinge. The drain outlet 11 on the vertical pipe 6 is located between the grid plate 16 and the corresponding baffle plate 17. A sampling tube 18 is provided on the side wall of the pressure relief box 7 on the other side of the grid plate 16.

[0026] In this embodiment, the drain port 11 is disposed on the side walls of the vertical pipe 6 and the stud 8 above the buffer mechanism 12 .

[0027] When in use, the arc rod 41 is rotated to rotate around the rotating shaft 43, so that the arc rod 41 is moved to the position below the top of the vertical pipe 6. At this time, the top of the vertical pipe 6 is inserted into the screw hole 5 and screwed to it, wherein the length of the vertical pipe 6 sliding into the screw hole 5 is limited by the protrusion 42, and the arc rod 41 is rotated to buckle at the bottom of the sewage pipe 1, and then the upper clamp 3 and the lower clamp 4 are locked and fixed by bolts, so that the sampling mechanism 2 is locked and fixed on the sewage pipe 1. At this time, the sampling mechanism 2 The screw connection between the vertical pipe 6 and the sewage pipe 1 can effectively enhance the connection stability and air tightness between the two. At the same time, the sewage pipe 1 can effectively prevent the vertical pipe 6 from continuing to rotate in the screw hole 5 by abutting the upper clamp 3 and the lower clamp 4, and prevent the vertical pipe 6 from rotating and rotating out of the screw hole 5. The lower clamp 4 is composed of an arc rod 41, a protrusion 42 and a rotating shaft 43, so that the vertical pipe 6 and the screw hole 5 can be smoothly screwed to complete the installation work, and at the same time, the sampling mechanism 2 is locked and fixed on the sewage pipe 1 after it is screwed and fixed;

[0028] The original state of the sampling mechanism 2 is as follows Figure 2 As shown, when sampling is required, Figure 3 As shown, the stud 8 is rotated to make the spiral in the vertical pipe 6 move upward, thereby driving the top of the stud 8 to slide into the sewage pipe 1, and also driving the circulation channel 9 to slide into the sewage pipe 1. At this time, the drain port 11 on the side wall of the stud 8 and the drain port 11 on the side wall of the vertical pipe 6 are staggered up and down, wherein the liquid in the sewage pipe 1 flows into the buffer cavity 10 through the circulation channel 9, and the inflowing liquid squeezes the buffer seat 125, thereby driving the slide bar 122 to slide downward in the connecting port, and at the same time, the spring 124 is stretched through the slider 123 to make it stretch, so as to buffer the liquid flowing into the buffer cavity 10 through the buffer mechanism 12 to reduce the flow rate and impact force, and in the above process, the serpentine circulation channel 9 can also reduce the flow rate and impact force of the inflowing liquid, and at the same time, the liquid slowly fills the internal space of the buffer cavity 10;

[0029] Then, the stud 8 is rotated downward so that the top of the flow channel 9 moves into the vertical pipe 6 to prevent the liquid in the sewage pipe 1 from continuing to enter. When the stud 8 moves down to the original position, the two sets of drain ports 11 are aligned, so that the liquid in the buffer chamber 10 can flow from the two sets of drain ports 11 to the pressure relief box 7 with a larger accommodating space than the buffer chamber 10. As the liquid in the buffer chamber 10 decreases, the spring 124 contracts to push the buffer seat 125 upward to drive the liquid at the bottom of the buffer chamber 10 to move upward and flow out near the drain port 11. When the liquid flowing into the pressure relief box 7 is slowly filled into the interior, it will squeeze the baffle 17 to rotate with the hinge as the center of the circle, so as to block and slow down the inflowing liquid through the baffle 17, and at the same time, the pressure relief box is depressurized and exhausted through the pressure relief valve 15, and finally discharged through the sampling tube 18 for sampling operation, so that high-pressure wastewater can be avoided from being sprayed onto the staff during sampling, and will not cause corrosion to clothes and skin.

[0030] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
