Description

Technical Field

[0001] This utility model relates to the field of wastewater detection, and in particular to a rapid detection device for industrial wastewater. Background Technology

[0002] Industrial wastewater has a complex composition that varies depending on the industry. It contains various suspended solids, acidic and alkaline substances, organic matter, heavy metals, etc. Rapid testing can quickly determine key indicators of wastewater, such as pH value, chemical oxygen demand, biochemical oxygen demand, and heavy metal content. This helps companies understand the degree of pollution in their wastewater in a timely manner so that they can take appropriate treatment measures.

[0003] A search revealed that Chinese Patent Publication No. CN218567338U discloses a rapid detection device for heavy metals in industrial wastewater. The device consists of a detector and a test tube inside a detection box. A head cover is connected to the back of the detection box via a hinge, and a protective cover is provided on one side of the head cover. The sampling tube is wrapped around the surface of a roller and extracted by a water pump. This device can automatically sample wastewater at different depths, improving the accuracy of the detection.

[0004] In the above technical solution, the automatic sampling of wastewater at different depths can be achieved by retracting and releasing the pipe to improve the detection accuracy. However, when the pipe enters wastewater at a deeper level, wastewater will remain on the outer wall of the pipe. Impurities in the wastewater adhere to the pipe and are prone to corrosion. At the same time, the wastewater can enter the tank and come into contact with the detection instrument and other equipment, causing pollution and increasing the cost of maintenance or replacement. Therefore, a rapid detection device for industrial wastewater is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rapid industrial wastewater detection device, which aims to improve the existing rapid industrial wastewater detection devices that lack the function of cleaning the surface of the sampling pipe after sampling, which leads to wastewater contact with other equipment in the tank and causes pollution, while reducing sewage corrosion and increasing maintenance or replacement costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid industrial wastewater detection device, comprising a storage box, a detector fixedly connected to the inner wall of the storage box, a roller rotatably connected to the inner wall of the storage box, a handle fixedly connected to the top of the roller, a connecting pipe wound around the outer wall of the roller, a pump fixedly connected to one end of the connecting pipe, a counterweight fixedly connected to the other end of the connecting pipe, a positioning frame provided on the surface of the storage box, an installation groove provided on the surface of the positioning frame, a telescopic rod fixedly connected to the inner wall of the installation groove, a spring sleeved on the outer wall of the telescopic rod, an arc-shaped plate fixedly connected to the end of the spring, a hook and loop fastener male face fixedly connected to the outer wall of the arc-shaped plate, a hook and loop fastener female face detachably connected to the side wall of the hook and loop fastener female face, a sponge fixedly connected to the outer wall of the hook and loop fastener female face, and a guide assembly provided on the surface of the arc-shaped plate.

[0007] As a further description of the above technical solution:

[0008] The positioning frame is fitted onto the outer wall of the storage box, and the inner surface of the sponge is in contact with the outer wall of the connecting tube.

[0009] As a further description of the above technical solution:

[0010] The end of the spring away from the arc-shaped plate is fixedly connected to the inner wall of the mounting groove.

[0011] As a further description of the above technical solution:

[0012] The guide assembly includes a groove, and a slider is slidably connected to the inner wall of the groove.

[0013] As a further description of the above technical solution:

[0014] The slide groove is formed on the outer wall of the arc-shaped plate near the telescopic rod, and the outer wall of the slide is rotatably connected to the movable end of the telescopic rod through a rotating shaft.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the storage box has a placement groove and a positioning hole, and a positioning rod is installed inside the positioning hole.

[0017] As a further description of the above technical solution:

[0018] The placement groove is fitted onto the outer wall of the connecting pipe.

[0019] As a further description of the above technical solution:

[0020] The top of the positioning rod is fixedly connected to the outer wall of the positioning frame, and the outer wall of the positioning rod is adapted to the inner wall of the positioning hole.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by combining a positioning frame, mounting groove, telescopic rod, spring, arc plate, sponge, and guide assembly, the surface of the connecting pipe can be cleaned after sampling in the wastewater. This prevents the wastewater from corroding the connecting pipe, while also preventing cross-contamination caused by residual wastewater components from the previous sampling on the surface of the connecting pipe, thus avoiding contamination of the test results. It also prevents residual wastewater in the connecting pipe from contaminating the internal equipment of the storage box, thereby improving the service life of the testing equipment and ensuring the accuracy of the test data.

[0023] 2. In this utility model, by providing a placement groove, positioning hole and positioning rod, the positioning is provided when the connecting pipe enters the wastewater for sampling, and at the same time the situation where the sponge is deviated when the connecting pipe is rolled up for cleaning is reduced, which may result in incomplete cleaning of the wastewater.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a rapid industrial wastewater detection device, comprising a storage box 1, a detector 2 fixedly connected to the inner wall of the storage box 1, a reel 3 rotatably connected to the inner wall of the storage box 1, a handle 4 fixedly connected to the top of the reel 3, a connecting pipe 5 wound around the outer wall of the reel 3, a pump 6 fixedly connected to one end of the connecting pipe 5, the output end of the pump 6 extending into a sampling tube, the sampling tube being fixedly placed in the storage box 1, wastewater being placed through the sampling tube and then drawn into a test tube through a syringe, and detected by the detector 2, a counterweight 7 fixedly connected to the other end of the connecting pipe 5, the counterweight 7 being annularly arranged, covering the connecting pipe 5 inside, increasing the weight of the opening of the connecting pipe 5 so that it can sink into the wastewater for sampling, and a positioning frame 8 provided on the surface of the storage box 1, the positioning frame 8 being fitted onto the storage box 1. On the outer wall, the surface of the positioning frame 8 is provided with an installation groove 9. The inner wall of the installation groove 9 is fixedly connected to a telescopic rod 10. The outer wall of the telescopic rod 10 is fitted with a spring 11. The end of the spring 11 away from the arc plate 12 is fixedly connected to the inner wall of the installation groove 9. The end of the spring 11 is fixedly connected to the arc plate 12. The outer wall of the arc plate 12 is fixedly connected to a hook and loop fastener male face 15. The side wall of the hook and loop fastener male face 15 is detachably connected to a hook and loop fastener female face 16. The outer wall of the hook and loop fastener female face 16 is fixedly connected to a sponge 17. The adhesion and separation of the hook and loop fastener female face 16 and the hook and loop fastener male face 15 can quickly replace or clean the sponge 17. The inner surface of the sponge 17 is in contact with the outer wall of the connecting tube 5. The sponge 17 can wipe the connecting tube 5 to prevent the connecting tube 5 from entering the wastewater and bringing impurities on its surface into the storage box 1.

[0033] Reference Figures 3-5 The surface of the arc plate 12 is provided with a guide assembly, which includes a groove 13. The groove 13 is opened on the outer wall of the arc plate 12 near the telescopic rod 10. The inner wall of the groove 13 is slidably connected to a slider 14. The outer wall of the slider 14 is rotatably connected to the movable end of the telescopic rod 10 through a pivot. The guide assembly can help the arc plate 12 deflect at different angles, which is convenient to adapt to the winding of the connecting tube 5 from different directions, and ensure the adhesion between the sponge wiper 17 and the surface of the connecting tube 5.

[0034] Reference Figure 3The outer wall of the storage box 1 is provided with a placement groove 18, which is fitted onto the outer wall of the connecting pipe 5. The outer wall of the storage box 1 is provided with a positioning hole 19, and a positioning rod 20 is provided inside the positioning hole 19. The top of the positioning rod 20 is fixedly connected to the outer wall of the positioning frame 8. The outer wall of the positioning rod 20 is adapted to the inner wall of the positioning hole 19. The positioning rod 20 is inserted into the positioning hole 19 to help fix the positioning frame 8 on the storage box 1 and prevent it from shifting.

[0035] Working principle: Pull the connecting pipe 5 to embed it into the placement groove 18. Manually reverse the handle 4 to control the drum 3 to release the connecting pipe 5. The counterweight 7 makes the connecting pipe 5 sink into the wastewater. The surface of the connecting pipe 5 is marked for easy observation of the depth of the pipe end submerged in the wastewater. The extraction pump 6 extracts the wastewater through the connecting pipe 5. The extracted wastewater enters the sampling cylinder for temporary storage. Before winding up the connecting pipe 5, align the positioning rod 20 with the positioning hole 19 and insert it so that the positioning frame 8 is locked onto the body of the storage box 1. During the insertion into the storage box 1, manually apply force to the two sets of sponge wipes 17 to compress the telescopic rod 10. After the positioning frame 8 is fixed, release the sponge wipes 17. The spring 11 rebounds after losing the compressive force, causing the telescopic rod 10 to extend. The retractor 10 is reset, allowing the two sets of sponge wipes 17 to come into contact with the wall of the connecting tube 5. Then, the control handle 4 drives the drum 3 to wind up the connecting tube 5. When the connecting tube 5 is wound up, the two sets of sponge wipes 17 can wipe the wastewater or impurities adhering to the tube wall, reducing the chance of wastewater residue on the connecting tube 5 entering the storage box 1. This avoids the risk of chemical substances in the wastewater corroding the connecting tube 5 and reducing its service life. At the same time, wiping the surface of the connecting tube 5 can prevent the residue of the previous sampling wastewater from causing cross-contamination of the sample and affecting the test data. It also prevents the residue on the surface of the connecting tube 5 from coming into contact with the internal equipment of the storage box 1 and causing contamination.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
