Description
Technical Field
[0001] This utility model relates to the field of PPR pipe technology, specifically to a PPR pipe antibacterial performance simulation experimental device. Background Technology
[0002] PP-R (polypropylene random) pipe, also known as PP-R pipe, random copolymer polypropylene pipe, or PPR pipe, is a type of pipe made from random copolymer polypropylene. Compared with traditional cast iron pipes, galvanized steel pipes, and cement pipes, PPR pipes have advantages such as energy and material saving, environmental protection, lightweight and high strength, corrosion resistance, smooth inner wall without scaling, simple construction and maintenance, and long service life. They are widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, power and fiber optic cable sheathing, industrial fluid transportation, agricultural irrigation, and other construction, municipal, industrial, and agricultural fields.
[0003] After PPR pipes are produced, their antibacterial properties are usually tested. However, traditional testing equipment has limited capabilities and cannot effectively simulate the antibacterial effects of pipes under different humidity and temperature conditions. Furthermore, after production, the pipes need to be cleaned with cleaning equipment before being transported to the testing equipment, which makes the process quite cumbersome. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a PPR pipe antibacterial performance simulation experimental device. This addresses the issue mentioned in the background that after PPR pipes are manufactured, it is generally necessary to test their antibacterial performance. However, traditional experimental equipment has limited capabilities and cannot effectively simulate the antibacterial effects of pipes under different humidity and temperature conditions. Furthermore, after production, the pipes need to be cleaned using cleaning equipment before being transported to the experimental device, which leads to a cumbersome operation.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a PPR pipe antibacterial performance simulation experimental device, comprising an experimental platform, four support legs fixedly installed at the bottom of the experimental platform, the four support legs being arranged in a rectangular array at the bottom of the experimental platform, three experimental boxes arranged linearly on the experimental platform, each of the three experimental boxes having a slot, a transparent plate being movably inserted into each slot, a handle fixedly installed at the top of each transparent plate, threaded rods rotatably installed on both end faces of each experimental box, a clamping plate rotatably installed on the inner end surface of each threaded rod, a knob fixedly installed on the outer end of each threaded rod, and two stabilizing rods fixedly installed on the outer end of each clamping plate, both of the stabilizing rods penetrating the experimental box.
[0006] Using the above technical solution, rotating the knob drives the threaded rod to rotate. When the threaded rod moves into the experimental chamber, it effectively clamps the PPR pipe coated with bacterial culture. Then, the operator inserts a transparent plate into the slot at the top of the experimental chamber. The handle on the transparent plate allows the operator to easily pull the plate out of the slot. After the transparent plate is inserted, the operator turns on the heating and humidifying components according to the required simulated temperature and humidity. This allows the experimental chamber to simulate the antibacterial properties of PPR pipes at different temperatures and humidity levels, thus improving the effectiveness of the simulation experiment.
[0007] Preferably, a humidification component and a heating component are provided at the top of the experimental chamber.
[0008] By adopting the above technical solution, the heating and humidifying components are turned on according to the required simulated temperature and humidity, which makes it easier to simulate the antibacterial properties of PPR pipes at different temperatures and humidity in the test chamber, thereby improving the effect of the simulation experiment.
[0009] Preferably, a processing box is provided at the rear of the upper surface of the experimental platform, the processing box having a cleaning chamber and a drying chamber, a water storage tank is provided at the bottom of the experimental platform, an inlet pipe is provided at the front end of the water storage tank, and a drain pipe is provided at the bottom of the water storage tank.
[0010] Using the above technical solution, water is introduced into the storage tank through the inlet pipe at the front end of the storage tank, and the liquid in the storage tank can be discharged through the drain pipe at the bottom of the storage tank.
[0011] Preferably, a liquid delivery pipe is provided at the rear end of the water storage tank, the liquid storage end of the liquid delivery pipe extends into the cleaning chamber, an atomizing nozzle is provided at the liquid outlet end of the liquid delivery pipe, and a pump body is provided on the liquid delivery pipe.
[0012] By adopting the above technical solution, the pump body is controlled so that the pump body's delivery pipe draws water from the storage tank. The drawn water is then sprayed out through the atomizing nozzles set on the outlet end of the delivery pipe, thus spraying it onto the PPR pipe.
[0013] Preferably, a water-leaking screen is provided inside the cleaning chamber, and support frames are fixedly installed inside both the cleaning chamber and the drying chamber. Two telescopic rods are provided at the top of the water storage tank, and the extension and retraction ends of the two telescopic rods extend into the cleaning chamber. A cleaning brush is fixedly installed at the extension and retraction ends of the telescopic rods. A dryer is provided inside the drying chamber, and a sealing door is provided at the front end of both the cleaning chamber and the drying chamber.
[0014] Using the above technical solution, the telescopic rod is controlled to drive the cleaning brush installed on the telescopic end to clean the stains on the PPR pipe, thus preventing the stains from affecting the experimental results of the PPR pipe. Then, the drain net sends water into the storage tank. After the PPR pipe is cleaned, the staff places the cleaned PPR pipe on the support frame in the drying chamber for support, and then turns on the dryer to dry the cleaned PPR pipe.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This PPR pipe antibacterial performance simulation experimental equipment uses a knob to rotate a threaded rod. As the threaded rod moves into the experimental chamber, it effectively clamps the PPR pipe coated with microbial agents. The operator then inserts a transparent plate into a slot at the top of the experimental chamber. A handle on the transparent plate allows the operator to easily remove it from the slot. After the transparent plate is inserted, the operator activates the heating and humidifying components according to the desired simulated temperature and humidity. This allows the experimental chamber to simulate the antibacterial performance of PPR pipes at different temperatures and humidity levels, thus improving the effectiveness of the simulation experiment.
[0017] 2. This PPR pipe antibacterial performance simulation experimental equipment uses a support frame placed inside the cleaning chamber to support the PPR pipe. The operator then controls the pump to draw water from the storage tank via the pump body's delivery pipe. The drawn water is then sprayed onto the PPR pipe through atomizing nozzles at the outlet of the delivery pipe. Finally, by controlling the telescopic rod, a cleaning brush installed at the telescopic end is used to remove dirt from the PPR pipe, preventing the dirt from affecting the experimental results.

[0024] 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.
[0025] Example 1:
[0026] Referring to Figures 1-5, a simulation experimental device for the antibacterial performance of PPR pipes is described. The experimental platform 1 has four fixed support legs 2 at its bottom, arranged in a rectangular array. Three experimental chambers 3 are arranged linearly on the platform 1. Each chamber 3 has a slot 4, into which a transparent plate 5 is movably inserted. A handle 6 is fixedly installed at the top of each transparent plate 5. Threaded rods 7 are rotatably mounted on both sides of each chamber 3. A clamping plate 8 is rotatably mounted on the inner surface of each threaded rod 7. A knob 9 is fixedly mounted on the outer end of each threaded rod 7. Two stabilizing rods 10 are fixedly mounted on the outer end of each clamping plate 8, both penetrating the chamber 3. A humidifying component 11 and a heating component 12 are located at the top of each chamber 3.
[0027] Working Principle: The simulation experimental equipment is supported by four support legs 2 installed at the bottom of the experimental platform 1. After the PPR pipe is cleaned, different bacterial strains are applied to the PPR pipe. The pipe is then placed into three experimental chambers 3 to simulate different temperatures, humidity levels, and bacterial strains. The operator rotates knob 9 to rotate threaded rod 7. As threaded rod 7 moves into the experimental chamber 3, it effectively clamps the bacterial-coated PPR pipe with clamping plates 8, thus... The plate remains stable inside the test chamber 3. The stabilizing rods 10 installed on both sides of the clamping plate 8 can prevent the clamping plate 8 from rotating when the threaded rod 7 moves it. Then, the staff inserts the transparent plate 5 into the slot 4 opened at the top of the test chamber 3. The handle 6 installed on the transparent plate 5 makes it easy for the staff to pull the transparent plate 5 out of the slot 4. After the transparent plate 5 is inserted into the slot 4, the staff turns on the heating component 12 and the humidifying component 11 according to the required simulated temperature and humidity. This makes it easier to simulate the antibacterial performance of PPR pipes at different temperatures and humidity inside the test chamber 3, thereby improving the effect of the simulation experiment.
[0028] Example 2:
[0029] Referring to Figures 1-5, a PPR pipe antibacterial performance simulation experimental device is described. A treatment box 13 is located at the rear of the upper surface of the experimental platform 1. The treatment box 13 contains a cleaning chamber 14 and a drying chamber 15. A water storage tank 16 is located at the bottom of the experimental platform 1. An inlet pipe 17 is located at the front end of the water storage tank 16, and a drain pipe 18 is located at the bottom of the water storage tank 16. A delivery pipe 19 is located at the rear end of the water storage tank 16, with its storage end extending into the cleaning chamber 14. An atomizing nozzle is provided at the liquid outlet end; a pump body 20 is provided on the liquid delivery pipe 19; a water leakage screen 21 is provided inside the cleaning chamber 14; support frames 22 are fixedly installed in both the cleaning chamber 14 and the drying chamber 15; two telescopic rods 23 are provided at the top of the water storage tank 16; the extension and retraction ends of the two telescopic rods 23 extend into the cleaning chamber 14; cleaning brushes 24 are fixedly installed on the extension and retraction ends of the telescopic rods 23; a dryer 25 is provided inside the drying chamber 15; and sealing doors 26 are provided at the front ends of both the cleaning chamber 14 and the drying chamber 15.
[0030] Working principle: Workers can add water to the storage tank through the inlet pipe 17 at the front end, and then drain the liquid from the tank through the drain pipe 18 at the bottom. When cleaning PPR pipes, workers first open the sealing door 26, then place the PPR pipe onto the support frame 22 inside the cleaning chamber 14 to support it. Workers then control the pump body 20, which draws water from the storage tank through the delivery pipe 19. The drawn water then flows out through the outlet end of the delivery pipe 19. The atomizing nozzles spray water onto the PPR pipes. Then, by controlling the telescopic rod 23, the cleaning brush 24 installed on the telescopic end is driven to clean the stains off the PPR pipes, thus preventing the stains from affecting the test results of the PPR pipes. Then, the drain net 21 sends water into the storage tank. After the PPR pipes are cleaned, the staff places the cleaned PPR pipes into the support frame 22 in the drying chamber 15 for support. Then, the dryer 25 is turned on to dry the cleaned PPR pipes.
