Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling technology, and in particular to an industrial wastewater sampling device. Background Technology
[0002] In industrial production processes, the management of industrial wastewater discharge is a crucial aspect of environmental protection. To ensure that wastewater discharge complies with relevant environmental standards and avoids pollution of natural water bodies, soil, and the ecological environment, sampling and testing of wastewater before discharge is an essential and vital task.
[0003] To facilitate sampling, existing technologies typically use sampling cylinders as sampling devices. The sampling cylinder is lowered into the industrial wastewater via a cable. After the wastewater enters the sampling cylinder, the cable is pulled back, and the wastewater in the sampling cylinder is poured into a test tube. However, this sampling device has the following problems:
[0004] 1. Industrial wastewater usually contains a large number of impurities, suspended solids, and chemical substances. After the sampling tube completes one sampling, a large number of pollutants will remain inside, making it impossible to perform a second sampling.
[0005] 2. The entire sampling process requires manual operation, which is not only cumbersome and inefficient, but also makes it easy to come into contact with industrial wastewater during sampling. Since industrial wastewater contains various toxic and harmful substances, it will pose a serious threat to health in the long run.
[0006] Based on the above problems, an industrial wastewater sampling device is proposed. Utility Model Content
[0007] The purpose of this invention is to solve the problems mentioned in the background art and to propose an industrial wastewater sampling device.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] An industrial wastewater sampling device includes a base and a sampling tube. A bracket and a winch are mounted on the base. A fixed pulley is rotatably connected to the upper end of the bracket. A pull rope is wound on the winch. A counterweight ball is wound around the end of the pull rope away from the winch and passes through the fixed pulley. The sampling tube is sleeved on the pull rope and its bottom abuts against the counterweight ball. A float is connected to the outer wall of the sampling tube. An auxiliary mechanism is provided on the bracket to assist the sampling tube in transferring wastewater samples and cleaning the inner wall of the sampling tube.
[0010] Preferably, the auxiliary mechanism includes a mounting plate, a circular cover plate connected to the top of the sampling tube, a first rope hole for the pull rope to pass through at the center of the cover plate, two ventilation holes at the first rope hole on the cover plate, the mounting plate being mounted on a bracket and located below a fixed pulley, a disc-shaped electromagnet being mounted at the bottom of the mounting plate, and a second rope hole for the pull rope to pass through the mounting plate and the electromagnet being coaxially arranged, the cover plate being made of ferromagnetic material.
[0011] Preferably, the electromagnet has a disc-shaped groove at its bottom, and a water pipe is installed on the mounting plate extending into the groove of the electromagnet. The other end of the water pipe is connected to tap water and a water valve.
[0012] Preferably, a sealing strip is provided at the bottom of the electromagnet.
[0013] Preferably, the bottom end of the sampling tube has a funnel-shaped structure, and the sampling tube is made of a transparent material.
[0014] Preferably, the counterweight ball is made of ceramic material.
[0015] Preferably, the float is made of polyethylene material.
[0016] Compared with the prior art, the advantages of this utility model are:
[0017] This invention allows for the sampling of industrial wastewater by controlling the raising and lowering of a rope. After sampling, the sampling tube is promptly rinsed for easy use in subsequent sampling operations. Throughout the entire sampling process, the operator does not come into contact with the sampling tube or the counterweight ball, effectively avoiding the opportunity for the operator to come into contact with the industrial wastewater and improving the safety of the sampling operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-3 As shown, an industrial wastewater sampling device includes a base 1 and a sampling tube 6. A bracket 2 and a winch 3 are installed on the base 1. A fixed pulley 5 is rotatably connected to the upper end of the bracket 2. A pull rope 4 is wound on the winch 3. A counterweight ball 8 is wound around the end of the pull rope 4 away from the winch 3 and passes through the fixed pulley 5. The sampling tube 6 is sleeved on the pull rope 4 and its bottom abuts against the counterweight ball 8. A float 9 is connected to the outer wall of the sampling tube 6. An auxiliary mechanism is provided on the bracket 2 to assist the sampling tube 6 in transferring wastewater samples and cleaning the inner wall of the sampling tube 6.
[0024] In this embodiment, the auxiliary mechanism includes a mounting plate 10, a circular cover plate 7 connected to the top of the sampling tube 6, a first rope hole 71 for the pull rope to pass through the center of the cover plate 7, two ventilation holes 72 located at the first rope hole 71 on the cover plate 7, the mounting plate 10 is mounted on the bracket 2 and located below the fixed pulley 5, a disc-shaped electromagnet 11 is mounted on the bottom of the mounting plate 10, the mounting plate 10 and the electromagnet 11 together have a second rope hole 12 for the pull rope to pass through, the second rope hole 12 is coaxially arranged with the electromagnet 11, and the cover plate 7 is made of ferromagnetic material.
[0025] In this embodiment, a disc-shaped groove 111 is provided at the bottom of the electromagnet 11, and a water pipe 13 is installed on the mounting plate 10, extending into the groove 111 of the electromagnet 11. The other end of the water pipe 13 is connected to tap water and a water valve to control the water supply to the water pipe 13.
[0026] In this embodiment, a sealing strip 112 is provided at the bottom of the electromagnet 11.
[0027] The sampling tube 6 has a funnel-shaped structure at the bottom and is made of transparent material to facilitate observation of the state inside the sampling tube. The counterweight ball 8 is made of ceramic material, which has good corrosion resistance and does not affect the sampling results.
[0028] In addition, the float plate 9 is made of polyethylene material, which has good corrosion resistance to water, salt, chemicals, etc., and is not easily corroded by substances in the water, resulting in a long service life.
[0029] Working process and its principle:
[0030] In operation, the winch 3 is activated to release the pull rope 4. The sampling tube 6 and the counterweight ball 8 will descend along with the release of the pull rope 4. Once the sampling tube 6 and the counterweight ball 8 enter the industrial wastewater, the sampling tube 6, influenced by the buoyancy of the float 9, will not continue to sink with the counterweight ball 8. After the sampling tube 6 separates from the counterweight ball 8, the industrial wastewater quickly flows into the sampling tube 6 from the bottom. At this time, the winch 3 is reversed to rewind the pull rope 4. The counterweight ball 8, which was originally sinking, is pulled up by the pull rope 4 and will block the bottom of the sampling tube 6. During the process of the counterweight ball 8 lifting the sampling tube 6, the sampling wastewater inside the sampling tube 6 will exert gravity on the funnel-shaped inner wall at the bottom of the sampling tube 6, making the counterweight ball 8 and the sampling tube 6 tightly connected, preventing wastewater leakage when the sampling tube 6 is lifted in the air. When the sampling tube 6 rises to its highest position (i.e., when the cover plate 7 is against the bottom of the electromagnet 11), the operator only needs to place the sampling cup on the bottom of the sampling tube 6, then energize the electromagnet 11 to generate a magnetic attraction force on the cover plate 7, and control the winch 3 to release the pull rope 4. Since the sampling tube 6 and the cover plate 7 are attracted by the electromagnet 11, they will not fall with the counterweight ball 8. After the wastewater in the sampling tube 6 loses the blockage of the counterweight ball 8, it quickly flows into the sampling cup, completing the wastewater sampling work. Afterwards, the water supply pipe 13 is opened to supply water. Tap water enters the sampling tube 6 through the water supply pipe 13, the groove 111 and the vent 72 in sequence, rinsing the inner wall of the sampling tube 6 and the counterweight ball 8, making it convenient for the next sampling.
[0031] Throughout the sampling process, the operators did not come into contact with the sampling tube 6 and the counterweight ball 8, effectively avoiding the opportunity for the operators to come into contact with the industrial wastewater and improving the safety of the sampling work.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
