Description

Technical Field

[0001] This utility model relates to the field of testing technology, specifically a scaling inhibition testing device. Background Technology

[0002] Scale formation refers to the phenomenon where dissolved minerals (such as calcium and magnesium) in water form solid precipitates during heating or evaporation. This phenomenon commonly occurs in water heaters, boilers, pipes, and other water-using equipment, affecting their thermal efficiency and lifespan. Scale formation is closely related to factors such as water hardness, temperature, pressure, and water flow rate. When water temperature rises, solubility decreases, and minerals begin to precipitate, accumulating over time to form solid scale, causing numerous inconveniences and losses in daily life and industrial production. Therefore, researching methods for controlling and preventing scale formation has become an important topic in the field of water treatment.

[0003] Chinese utility model patent 201922103996.X discloses a laboratory-scaled simulating device, comprising a heater, a heat exchanger, and a cooler. A radiator and a buffer tube are installed between the heat exchanger and the cooler. The heater raises the temperature of the heating medium, while the cooler, containing a cooling medium, lowers the temperature of the heating medium. Heat exchange occurs between the heating and cooling media in the heat exchanger, and the radiator cools the heated cooling medium. The buffer tube regulates the flow rate of the cooling medium into the heat exchanger. Since the solubility of most substances decreases with increasing temperature, a large amount of scale will be generated in the heat exchanger. The use of a curved, transparent heat exchanger facilitates the assessment of the scale-removing and scale-preventing effects of chemical scale inhibitors and electronic scale removers by observing changes in the transparency of the heat exchange surface. The entire device is simple, quick, and provides a clear and intuitive way to determine the scale-removing and scale-preventing effects.

[0004] In the actual use of the above-mentioned patent, once scale forms in the water pipes, it is difficult to clean. If it is not cleaned in time, it will affect the results of the next test. In addition, the existing tests cannot fully simulate the actual environment, such as water flow rate and velocity, which will affect the final test results. Therefore, a scale inhibition test device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a scale inhibition test device to solve the problems mentioned in the background art, such as the difficulty in cleaning scale once it forms in water pipes, and the inability to adjust the water flow rate and velocity, which affects the experimental structure.

[0006] The technical solution of this utility model is:

[0007] It includes two heating components, each including a heating water tank. The upper side wall of the heating water tank is connected to a water inlet pipe, and an electric heating rod is fixedly connected to the inner wall of the heating water tank. A water supply component is connected between the lower and upper ends of the heating water tank. Multiple sealing components are fixedly connected to the water supply component, and the multiple sealing components are respectively distributed at both ends and the middle of the water supply component. An adjustment component is fixedly connected between the two water supply components, and a drive component is fixedly connected to the side wall of the heating water tank.

[0008] Furthermore, the sealing assembly includes a square box communicating with the water supply assembly. The water supply assembly includes a fixed half-pipe fixedly connected to the square box. An adjusting half-pipe is provided on one side of the fixed half-pipe. Two insert plates inserted into the fixed half-pipe are fixedly connected to the adjusting half-pipe. A cover plate is fixedly connected to the side wall of the adjusting half-pipe. The sealing assembly also includes two sealing plates fixedly connected inside the square box. Two one-way valves are fixedly connected to each of the two sealing plates. A water bladder located between the two sealing plates is connected to the square box. The adjusting assembly includes two horizontal plates fixedly connected to the adjusting half-pipe. A pull rod is fixedly connected between the two horizontal plates.

[0009] By setting up water supply components, sealing components, and regulating components, the regulating half-pipe can be moved by pulling the lever, thereby increasing the water intake of the water supply components without preventing leakage.

[0010] Furthermore, the drive assembly includes a motor plate fixedly connected between the heating water tank and the square box, a motor fixedly connected to the side wall of the motor plate, a rotating shaft fixedly connected to the output end of the motor, a disc fixedly connected to the end of the rotating shaft away from the motor, a movable frame slidably connected between the two square boxes, and a hinge rod hinged to the eccentric position of the movable frame and the disc.

[0011] By setting up a drive component, the two sets of water bladders can be driven by a motor to expand and contract at the same frequency, so that the two sets of water can be tested at the same flow rate, thus achieving a better comparative effect.

[0012] This utility model provides an improved scale inhibition testing device, which has the following improvements and advantages compared with the prior art:

[0013] Firstly, this utility model can adjust the water flow rate by adjusting the regulating half-pipe, thereby meeting different test requirements. In addition, the regulating half-pipe can be disassembled, which facilitates the cleaning of the inside of the water supply component, thereby reducing the impact of scale on the next test.

[0014] Secondly, this invention can adjust the water flow rate through the drive component, ensuring that two different water qualities can be tested at the same flow rate, thus achieving an effective comparative effect. Attached Figure Description

[0027] The following will be combined with the appendix Figures 1 to 5 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0028] This utility model provides an improved scale inhibition testing device, such as... Figure 1 - Figure 5As shown, the device includes two heating components 1. Each heating component 1 includes a heating water tank 101. A water inlet pipe 102 is connected to the upper side wall of the heating water tank 101. An electric heating rod 103 is fixedly connected to the inner wall of the heating water tank 101. A water supply component 2 connects the lower and upper ends of the heating water tank 101. Multiple sealing components 3 are fixedly connected to the water supply component 2, and the multiple sealing components 3 are distributed at both ends and the middle of the water supply component 2. The sealing components 3 at both ends of the water supply component 2 are connected to and fixed to the heating water tank 101. An adjusting component 4 is fixedly connected between the two water supply components 2. A driving component 5 is fixedly connected to the side wall of the heating water tank 101.

[0029] In this embodiment: after adding different water qualities into the two heating water tanks 101, the water is heated by the electric heating rod 103 to test the scale formation in a static state. After the test, the driving component 5 drives the water through the water conveying component 2 and back into the heating water tank 101 to realize the scale formation when the water is in a circulating state. The orifice size of the water conveying component 2 can be adjusted by the adjusting component 4 to regulate the water flow rate, thereby simulating the scale formation environment under different flow rates.

[0030] In the above embodiments, in order to adjust the orifice size of the water conveying component 2 to achieve the purpose of adjusting the water flow rate, the following method can be adopted:

[0031] The sealing assembly 3 includes a square box 301 that communicates with the water supply assembly 2. The water supply assembly 2 includes a fixed half-pipe 201 that is fixedly connected to the square box 301. An elliptical hole is drilled in the square box 301. An adjusting half-pipe 202 is provided on one side of the fixed half-pipe 201. Two insert plates 203 that are inserted into the fixed half-pipe 201 are fixedly connected to the adjusting half-pipe 202. Sealing strips are fixedly connected to the contact surfaces of the adjusting half-pipe 202 and the insert plates 203 with the square box 301. These are not shown in the figure. This can increase the sealing between the adjusting half-pipe 202 and the insert plates 203 and the square box 301. A cover plate 204 is fixedly connected to the side wall of the adjusting half-pipe 202. Sealing strips are also fixedly connected to the contact surfaces of the cover plate 204 with the square box 301. In this way, when the adjusting half-pipe 202 moves, the cover plate 204 can block the elliptical hole of the square box 301, thereby preventing water leakage. The sealing assembly 3 located in the middle of the water conveying assembly 2 also includes two sealing plates 302 fixedly connected inside the square box 301. Two one-way valves 303 are fixedly connected to each of the two sealing plates 302. A water bladder 304 located between the two sealing plates 302 is connected to the square box 301. The adjusting assembly 4 includes two horizontal plates 401 fixedly connected to the adjusting half-pipe 202. A pull rod 402 is fixedly connected between the two horizontal plates 401.

[0032] In a preferred embodiment, by pulling the lever 402, the lever 402 drives the two horizontal plates 401 to pull the adjusting half-pipes 202, causing multiple adjusting half-pipes 202 to move simultaneously. This movement method ensures that the orifice sizes of the two sets of water supply components 2 are the same. When it is necessary to reduce the orifice size, the lever 402 can be pushed to move the adjusting half-pipes 202. At this time, the adjusting half-pipes 202 move as shown in the image. Figure 5 The states are the same.

[0033] refer to Figure 4 and Figure 5 In a preferred embodiment, the drive assembly 5 includes a motor plate 501 fixedly connected between the heating water tank 101 and the square box 301. A motor 502 is fixedly connected to the side wall of the motor plate 501. A rotating shaft 503 is fixedly connected to the output end of the motor 502. A disc 504 is fixedly connected to the end of the rotating shaft 503 away from the motor 502. A movable frame 505 is slidably connected between the two square boxes 301. A hinge rod 506 is hinged to the eccentric position of the movable frame 505 and the disc 504.

[0034] In this embodiment: when the motor 502 starts, the rotating shaft 503 drives the disc 504 to rotate, which in turn pulls the moving frame 505 to move back and forth through the hinge rod 506, thereby squeezing the two sets of water bladders 304. During the squeezing process of the water bladders 304, the two one-way valves 303 are continuously opened and closed under the pressure of the water, thereby achieving the function of water transportation. When the expansion and contraction frequency of the water bladders 304 is higher, the speed of the motor 502 needs to be adjusted, so as to adjust the water flow rate. This can better simulate the test environment of different flow rates.

[0035] Working principle: When conducting the experiment, the researchers first open the water inlet pipe 102 and add water of two different qualities into the two heating water tanks 101 respectively. Then, the water is heated by the electric heating rod 103 to test the scale formation in a static state.

[0036] Then the researchers started the motor 502, which drove the disc 504 to rotate through the shaft 503. In turn, the hinge rod 506 pulled the moving frame 505 to move back and forth, which could squeeze the two sets of water bladders 304. During the squeezing process of the water bladders 304, the water pressure caused the two one-way valves 303 to open and close continuously, which in turn drove the water through the water conveying component 2 and back into the heating water tank 101. When the water is in a circulating state, the formation of scale is affected. When the extension and retraction frequency of the water bladders 304 is higher, the speed of the motor 502 needs to be adjusted, so as to regulate the water flow rate.

[0037] When it is necessary to adjust the water flow rate, the researchers pull the lever 402, which drives the two horizontal plates 401 to pull the adjusting half-pipe 202, so that multiple adjusting half-pipes 202 can move at the same time, thereby adjusting the orifice size of the water supply component 2 and realizing the water flow rate.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
