Description

Technical Field

[0001] This utility model relates to the field of scale inhibitor concentration measurement technology, specifically a scale inhibitor concentration monitoring device. Background Technology

[0002] Scale inhibitors are chemical agents used to prevent dissolved inorganic salts in water from forming scale on equipment surfaces. Their main working principle involves inhibiting scale formation through chelation, dispersion, and lattice distortion. Chelation refers to the formation of stable chelates between certain functional groups in the scale inhibitor and scale-forming metal ions such as calcium and magnesium in the water. For example, ethylenediaminetetraacetic acid (EDTA) scale inhibitors can form chelates with calcium ions with a cyclic structure, thus preventing the metal ions from participating in the scale formation process. Dispersion occurs when the scale inhibitor adsorbs onto the surface of tiny calcium carbonate and other crystalline particles, giving them the same charge and generating electrostatic repulsion, thereby preventing particle aggregation and scale formation. In circulating cooling water systems of thermal power plants, steel mills, and chemical plants, large amounts of cooling water evaporate and concentrate during circulation, increasing the concentration of calcium and magnesium ions and making it prone to scale formation. Using scale inhibitors can effectively prevent scale formation on cooling equipment.

[0003] Traditional circulating water scale inhibitors are mainly composed of phosphorus-containing organic compounds. With increasingly stringent standards for factory wastewater discharge and the serious harm of phosphorus to natural water, circulating water treatment agents are developing towards environmentally friendly water treatment agents. Existing scale inhibitor concentration detection devices, such as the reverse osmosis scale inhibitor concentration measuring device disclosed in publication number "CN214374663U", use "fixed screws and threaded grooves to cooperate with the first and second triangular protective frames, which facilitates a better working environment through enclosed storage protection." However, it is cumbersome to disassemble and install the protective frames by rotating the bolts, and the sharp corners of the triangular protective frames can easily cause injury to personnel.

Two second sprockets are rotatably connected to the upper surface of the protective shell. A groove is provided on the lower surface of the protective top plate, and a second lead screw is fixed to the inner wall of the groove of the protective top plate.

[0014] Preferably, the first sprocket and the second sprocket are arranged correspondingly, and a transmission chain is installed between the outer surface of the first sprocket and the outer surface of the second sprocket.

[0017] Using the above technical solution, the rotation of the second sprocket causes the second lead screw and the protective top plate to move.

[0019] 1. The device is equipped with a first lead screw and a transmission arm. When the device is working, the transmission gear drives the linkage gear and the first lead screw to rotate. The first lead screw drives the support slider to slide horizontally through the thread. Finally, the support slider pushes the transmission arm to rotate vertically, which facilitates the transmission arm to support the support slide plate. This is beneficial for storing and protecting the liquid concentration detector when not in use, and for pushing the liquid concentration detector to rise when in use, which increases the convenience of operation.

[0020] 2. The device is equipped with a transmission gear and a linkage gear. When the device is working, rotating the transmission gear allows it to drive the two linkage gears to rotate through the tooth block. The two linkage gears then drive the first lead screw to rotate simultaneously. The first lead screw drives the support slider to move through the thread, which allows the transmission arms on both sides to support the support slide plate synchronously. This improves the uniformity of the support slide plate's rise, reduces wear, and extends its service life.

[0021] 3. A second sprocket and a second lead screw are provided so that when the device is working, the first lead screw drives the first sprocket to rotate, and the first sprocket drives the second sprocket to rotate through the transmission chain. This causes the second sprocket to drive the second lead screw and the protective top plate to move horizontally through the thread, which facilitates the automatic opening and closing of the two protective top plates when the liquid concentration detector extends and retracts, thereby increasing the ease of use of the device.

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.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a scale inhibitor concentration monitoring device, including a protective shell 1, a protective top plate 2, a support slide plate 3, a liquid concentration detector 4, a first cavity 5, a transmission gear 6, a linkage gear 7, a first lead screw 8, a support slider 9, a transmission arm 10, a second cavity 11, a first sprocket 12, a second sprocket 13, and a second lead screw 14. The protective shell 1 has a limit block on its upper surface, and the protective shell 1 is slidably connected to two protective top plates 2 through the limit block. The shaft of the transmission gear 6 passes through the inner wall of the first cavity 5 and also passes through the front surface of the protective shell 1. The transmission gear 6 is meshed with two linkage gears 7 respectively, and the two linkage gears 7 are symmetrically arranged. When using this device, the liquid concentration detector 4 is fixedly installed on the upper surface of the support slide plate 3, and a wiring harness opening is opened on the surface of the protective shell 1 to facilitate wiring. The liquid concentration detector 4 is sealed and protected by the protective shell 1 and the protective top plate 2.

[0031] The upper surface of the protective housing 1 is provided with a groove, and the inner wall of the groove of the protective housing 1 is slidably connected to a support slide plate 3. A liquid concentration detector 4 is fixedly installed on the lower surface of the support slide plate 3. A first cavity 5 is opened on the bottom surface of the groove of the protective housing 1. A transmission gear 6 is rotatably connected to the inner wall of the first cavity 5, and two linkage gears 7 are rotatably connected to the inner wall of the first cavity 5. A first lead screw 8 is threadedly connected to a support slider 9, and the two support sliders 9 are symmetrically arranged. One end of the transmission arm 10 is rotatably connected to the support slide plate 3. When using this device, by rotating the transmission gear 6, the transmission gear 6 drives the two linkage gears 7 to rotate, and the linkage gears 7 drive the first lead screw 8 to rotate. The first lead screw 8 drives the support slider 9 to slide horizontally through the thread, and the support slider 9 drives the transmission arm 10 to rotate vertically.

[0032] One end of the shaft of the linkage gear 7 is fixedly connected to a first lead screw 8. Two support sliders 9 are slidably connected to the inner wall of the first cavity 5. The linkage mechanism includes a first sprocket 12, which is rotatably connected to the lower inner wall of the second cavity 11. Two second sprockets 13 are rotatably connected to the upper surface of the protective shell 1. A groove is provided on the lower surface of the protective top plate 2, and a second lead screw 14 is fixed to the inner wall of the groove of the protective top plate 2. The shaft of the first sprocket 12 passes through the inner wall of the second cavity 11, and the shaft of the first sprocket 12 is fixedly connected to the shaft of the first lead screw 8. The two first sprockets 12 are symmetrically arranged. After the two support sliders 9 slide close together, the support sliders 9 drive the transmission arm 10 to rotate vertically and support the support slide plate 3, so that the support slide plate 3 can drive the liquid concentration detector 4 to rise, thus facilitating its extension for use.

[0033] The upper end of the supporting slider 9 is rotatably connected to the transmission arm 10. The protective shell 1 has two second cavities 11 on its side. The second cavity 11 is equipped with a linkage mechanism, which drives the second sprocket 13 through the first sprocket 12, so that the second sprocket 13 drives the protective top plate 2 to open and close automatically through the second screw 14.

The side surface of the second sprocket 13 is provided with a threaded hole, and the second sprocket 13 and the second screw 14 are threadedly connected. The two second screws 14 are arranged symmetrically. When the first screw 8 rotates, the first screw 8 drives the first sprocket 12 on the inner wall of the second cavity 11 to rotate. At the same time, the first sprocket 12 drives the second sprocket 13 to rotate through the transmission chain. Then the threaded hole of the second sprocket 13 drives the second screw 14 and the protective top plate 2 to slide horizontally, so that the protective top plate 2 can automatically open and close when the liquid concentration detector 4 moves in extension and retraction, which improves the convenience of using this device.

The liquid concentration detector 4 is protected by the protective shell 1 and the protective top plate 2. During operation, the transmission gear 6 drives the two linkage gears 7 and the first lead screw 8 to rotate, so that the first lead screw 8 drives the support slider 9 to slide horizontally. In turn, the support slider 9 drives the transmission arm 10 to rotate vertically, thereby supporting the support slide plate 3 and the liquid concentration detector 4. After the first lead screw 8 rotates, it drives the first sprocket 12 on the inner wall of the second cavity 11 to rotate. The first sprocket 12 drives the second sprocket 13 to rotate through the transmission chain. This facilitates the second sprocket 13 to drive the second lead screw 14 and the protective top plate 2 to slide horizontally for automatic opening and closing, increasing the overall practicality.
