Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection equipment, in particular to a sampling device for industrial wastewater detection. Background Technique

[0002] Industrial wastewater usually includes production wastewater and production sewage. According to the products of industrial enterprises and the different processing objects, various different wastewaters can be classified; industrial wastewater must be harmlessly treated and discharged at a designated location only after passing water quality detection and meeting the standards. Therefore, in modern industry, the detection of industrial wastewater is the daily basic work of each industrial enterprise. According to different wastewaters, there are usually different sampling methods, and the wastewater sampling equipment is also different.

[0003] Most of the existing wastewater sampling equipment currently uses common containers such as water buckets and glass bottles for sampling, which can only sample shallow waters and basically lack means to stir the water body to be sampled. Chemical wastewater usually has precipitation or stratification, so the integrity of elements in the sample is omitted and it is not rigorous enough.

[0004] In order to solve the above problems, we made improvements and proposed a sampling device for industrial wastewater detection. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The utility model provides a sampling device for industrial wastewater detection, including a water suction pipe. On the left side of the top of the outer surface of the water suction pipe, a handle is fixedly arranged; a push-pull rod is telescopically arranged inside the water suction pipe, and the top of the push-pull rod passes through the top surface of the water suction pipe; on the right side of the top of the outer surface of the water suction pipe, a protective box is fixedly welded; a water pumping port is arranged at the bottom of the water suction pipe, a rotating shaft is rotatably arranged inside the protective box, and the bottom end of the rotating shaft passes through the bottom surface of the protective box and extends to a position beyond the horizontal position of the water pumping port; a stirring paddle is fixedly arranged at the bottom of the rotating shaft, and a first bevel gear is fixedly arranged in the middle of the part of the rotating shaft located inside the protective box; a rocker is rotatably arranged on the right side of the protective box; the left end of the rocker passes through the protective box, and a second bevel gear is fixedly arranged at the left end of the rocker; the first bevel gear and the second bevel gear are meshed.

[0007] As a preferred technical solution of the utility model, a grip is fixedly arranged at the top of the push-pull rod; a rubber piston is fixedly arranged at the bottom of the push-pull rod, and the side surface of the rubber piston is closely attached to the inner wall of the water suction pipe.

[0008] As a preferred technical solution of the present utility model, a connecting pipe is provided on the outer surface of the water pumping port. Threads are provided on the inner wall of the connecting pipe and the outer surface of the water pumping port, and the water pumping port and the connecting pipe are detachably connected by the threads.

[0010] The beneficial effects of the present utility model are as follows: for this sampling device for industrial wastewater detection, by adding a rocker bevel gear structure, when the device reaches the sampling depth, it can stir and mix the wastewater and sediment, and then pump water for sampling, so as to obtain a relatively complete industrial wastewater sample including sediment at one time, without the need for multiple stratified samplings. When the depth of the wastewater is relatively deep, connecting pipes with different lengths of extended water suction pipes can be connected according to different depths to achieve deep stratified sampling, ensuring that the composition of the wastewater sample is more complete and the sampling is more rigorous.

[0016] The following is a description of the preferred embodiments of the present utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0017] Embodiment: As Figures 1-3As shown in the figure, a sampling device for industrial wastewater detection includes a water suction pipe 1. On the left side of the top end of the outer surface of the water suction pipe 1, a handle 2 is fixedly arranged. A push-pull rod 3 is telescopically arranged inside the water suction pipe 1, and the top end of the push-pull rod 3 passes through the top surface of the water suction pipe 1. On the right side of the top end of the outer surface of the water suction pipe 1, a protective box 4 is fixedly welded. At the bottom of the water suction pipe 1, a water pumping port 5 is arranged. Inside the protective box 4, a rotating shaft 8 is rotatably arranged. The bottom end of the rotating shaft 8 passes through the bottom surface of the protective box 4 and extends to a horizontal position beyond the water pumping port 5. At the bottom of the rotating shaft 8, a stirring paddle 10 is fixedly arranged. In the middle of the part of the rotating shaft 8 located inside the protective box 4, a first bevel gear 9 is fixedly arranged. On the right side of the protective box 4, a rocker 11 is rotatably arranged. The left end of the rocker 11 passes through the protective box 4, and a second bevel gear 12 is fixedly arranged at the left end of the rocker 11. The first bevel gear 9 and the second bevel gear 12 are meshed with each other.

[0018] At the top of the push-pull rod 3, a grip 6 is fixedly arranged. At the bottom of the push-pull rod 3, a rubber piston 7 is fixedly arranged, and the side surface of the rubber piston 7 is closely attached to the inner wall of the water suction pipe 1.

[0021] Working principle: For this sampling device for industrial wastewater detection, when the water depth is relatively shallow under normal circumstances, the connecting pipe 13 and the extension water suction pipe 16 can be rotated and disassembled. After submerging the device to a suitable position close to the bottom, rotate the rocker 11 to drive the stirring paddle 10 to stir the industrial wastewater and sediment in the sampling space, so that the wastewater and sediment within the sampling position range are mixed evenly. Subsequently, pull the grip 6 to pump the evenly mixed sample wastewater into the water suction pipe 1 to complete the sampling. When the water depth is relatively deep, the connecting pipe 13 and the extension water suction pipe 16 can be connected. According to different depths, a connecting pipe 13 with a different length of the extension water suction pipe 16 can be selected, and the sampling depth can be adjusted according to the submerged length of the extension water suction pipe 16 for stratified sampling.
