Description

Technical Field

[0001] The utility model relates to the field of wastewater environmental assessment equipment, in particular to an automatic wastewater sampling and detection device. Background Art

[0002] The purpose of sampling industrial wastewater is to facilitate subsequent environmental impact assessment of water quality. If the water quality does not meet the standard, it needs to be treated in time to avoid polluting the environment. For environmental protection, the treatment of industrial wastewater is more important than the treatment of urban sewage. The existing industrial wastewater sampling equipment is large in size and inconvenient for sampling personnel to carry. When sampling water quality in different areas, the entire equipment needs to be moved together, which is labor-intensive. As sampling personnel have higher and higher requirements for sampling equipment, some box-type automatic sampling devices have also appeared on the market. However, during the sampling process, the sampled water of the automatic sampling device will produce precipitation after standing, resulting in the inability to fully mix the objects to be tested. The inability to fully mix will affect the subsequent water quality detection data and affect the subsequent detection results.

[0003] After searching, an automatic sampling device for industrial wastewater with application number CN202221862799.1 can absorb and stir wastewater to improve the rigor of the experiment. However, since the water inlet pipe of the device is a fixed design when sampling, the sampling range is reduced and the universality is reduced. In addition, the water storage box of the device is also fixed. During multiple uses, it is possible that samples are contaminated with each other, affecting subsequent detection results.

The inner cavity is provided with a connecting mechanism 9 which connects the working box 1 and the storage barrel 10. The surface of the storage barrel 10 is connected with a drain pipe 11. When the utility model is in use, the water inlet end 4 can make an arc-shaped reciprocating motion under the action of the swing mechanism 6, thereby increasing the water absorption range of the water inlet end 4, and avoiding the small water absorption range affecting the rigor of the experiment. In addition, under the action of the connecting mechanism 9, it is convenient for the staff to disassemble the storage barrel 10, and then it is convenient to clean and wash the storage barrel 10, further improving the rigor of the experiment.

[0021] The swing mechanism 6 includes a motor 61 fixed to the surface of the fixing member 5 and a limit member 65 fixed to the surface of the working box 1. The output shaft of the motor 61 is fixed with a turntable 62, and a rotating block 63 is fixed to the surface of the turntable 62. A swing member 64 with a hollow slide groove is rotatably arranged on the surface of the limit member 65. The rotating block 63 slides on the slide groove surface of the swing member 64. A driving block 66 is fixed to one end of the swing member 64, and the harder end of the water inlet end 4 is fixed to the inner cavity of the driving block 66. In this embodiment, through the arrangement of the motor 61, the turntable 62, the rotating block 63, the swing member 64, the limit member 65 and the driving block 66, the staff can use the motor 61. Under the action of the motor 61, the turntable 62 rotates, and the rotating block 63 rotating on the surface of the turntable 62 can slide in the inner cavity of the swing member 64, and then under the restriction of the limit member 65, the swing member 64 makes a reciprocating arc motion, and then the driving block 66 on the surface of the swing member 64 drives the water inlet end 4 to swing in an arc.

[0022] The motor 61 is a servo motor and has a built-in brake device. In this embodiment, through this arrangement, the water suction position of the water inlet end 4 can be kept stable when the water inlet end 4 does not need to swing.

[0023] The stirring mechanism 7 includes a motor 71 fixed to the inner cavity of the working box 1, and the output shaft of the motor 71 is provided with a rotating shaft 72 through a bevel gear transmission, and a plurality of stirring rods 73 are fixed to the surface of the rotating shaft 72. In this embodiment, through the arrangement of the motor 71, the rotating shaft 72 and the stirring rod 73, under the action of the motor 71, the rotating shaft 72 can drive the stirring rod 73 to stir the sewage in the inner cavity of the storage barrel 10.

[0024] The connecting mechanism 9 includes a sliding rod 93 fixedly sliding on both sides of the inner cavity of the connecting shell 8 and a mother block 91 fixed on both sides of the surface of the storage barrel 10. A sub-block 92 slides on the surface of the sliding rod 93, a connecting plate 95 is fixed on one side of the surface of the sub-block 92, and a pulling rod 96 is fixed on the other end of the sliding rod 93. A spring 94 is sleeved on the surface of the sliding rod 93, one end of the spring 94 is fixed to the surface of the connecting plate 95, and the other end of the spring 94 is fixed to the inner cavity of the connecting shell 8. In this embodiment, through the mother block 91 and the sub-block 92 , the sliding rod 93, the spring 94, the connecting plate 95 and the pulling rod 96 are arranged. When the mother block 91 and the child block 92 fit together, the child block 92 can slide on the surface of the sliding rod 93 together with the connecting plate 95 under the squeezing of the mother block 91, so that the storage barrel 10 and the mother block 91 can enter the specified position, and under the action of the spring 94, the stability of the mother block 91 and the child block 92 when in contact is improved. In addition, under the action of the pulling rod 96, it is convenient for the staff to release the contact between the mother block 91 and the child block 92.

[0025] The contact surfaces of the parent block 91 and the child block 92 are both designed to be inclined. In this embodiment, this arrangement improves the smoothness of the contact and sliding between the parent block 91 and the child block 92.

[0026] Working principle: When in use, the staff can use the water suction pump 2 to transport sewage to the storage barrel 10 through the water outlet 3 and the water inlet 4, and when transporting sewage, in order to improve the universality of the sample, the staff can use the swing mechanism 6. Under the action of the swing mechanism 6, the water inlet 4 is swung, thereby increasing the water absorption range and making the sampling more rigorous. With the cooperation of the water outlet 3, the sewage in the water inlet 4 enters the storage barrel 10, and under the action of the stirring mechanism 7, the sewage precipitation can be avoided. In addition, under the action of the connecting mechanism 9, the connection between the storage barrel 10 and the working box 1 can be disconnected, thereby facilitating the staff to clean the storage barrel 10 and avoid mutual contamination between samples. For the cleaning of the water outlet 3 and the water inlet 4, the staff can also achieve the purpose of cleaning by sucking clean water for flushing.
