Description

Technical Field

[0001] This utility model relates to the field of air conditioning water circulation treatment technology, specifically a dirt dissolving and cleaning device. Background Technology

[0002] HVAC systems require circulating water pipes, which typically include pre-filters and circulating water tanks. The circulating water tank serves to circulate and store water. However, it lacks a filtration system, and as water quality changes, scale forms on the inner walls of the tank. This scale accumulates on the inner walls (circumferential and upper / lower walls) and, if not cleaned promptly, can easily break off and clog subsequent pipes as the water flows. It can also corrode the inner walls of the circulating water tank.

[0003] In the prior art, to solve the above problems, the circulating water tank is usually descaled regularly. The descaling method is to add a descaling agent to the circulating water tank. The descaling agent is mixed with the water and then dissolves the dirt. The dissolved dirt will fall off by itself and mix into the water in the circulating water tank. Opening the drain pipe at the bottom of the circulating water tank can discharge the sewage, thereby achieving the cleaning treatment.

[0004] However, the existing technology has its shortcomings in use: the water in the circulating water tank has poor flow, the dirt and chemicals dissolve slowly, and the dirt falls off slowly. Moreover, some dirt still does not fall off easily after dissolution. In other words, the dirt is slowly removed during dissolution and cleaning, resulting in low cleaning efficiency. After dissolution and cleaning, a large amount of dirt will remain on some parts of the inner wall of the circulating water tank. When this dirt falls off later, it still poses a risk of clogging subsequent pipelines. Therefore, the existing technology has the shortcomings of low dirt cleaning efficiency and incomplete cleaning.

[0005] Therefore, this utility model provides a dirt dissolving and cleaning device. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dirt dissolving and cleaning device to solve the problems mentioned in the background technology. This utility model has the function of flushing and scraping the inner wall of the circulating water tank, which can accelerate the fusion and dissipation of the agent and dirt, and greatly improve the efficiency of dirt dissolving and cleaning.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a dirt dissolving and cleaning device, comprising a cylindrical circulating water tank, a feeding pipe and a water replenishment pipe fixedly installed at the top of the circulating water tank, an outlet pipe fixedly connected to the outer peripheral wall of the circulating water tank near the bottom, a left pipe and a right pipe respectively installed on the two sides outside the circulating water tank, two sets of circumferentially symmetrical connecting pipes tangentially connected to the outer wall of the circulating water tank, one end of the two sets of connecting pipes being fixedly connected to the left pipe and the right pipe respectively, a water inlet pipe fixedly connected to the bottom of the circulating water tank, the bottom end of the water inlet pipe being connected to the bottom of the left pipe and the right pipe through a transmission pipe, a water pump being connected in series on the water inlet pipe, a rectangular frame being placed inside the circulating water tank, the rectangular frame being rotatably connected to the circulating water tank and having rubber scrapers on both sides that abut against the inner wall of the circulating water tank.

[0008] Furthermore, an upper positioning shaft is fixedly connected to the middle of the top of the rectangular frame, and an upper positioning tube sleeved on the outside of the upper positioning shaft is fixedly connected to the top of the circulating water tank. The upper positioning tube and the upper positioning shaft are rotatably engaged.

[0009] Furthermore, a lower positioning shaft is fixedly connected to the middle of the bottom end of the rectangular frame, the water inlet pipe is located in the middle of the bottom of the circulating water tank, and a lower positioning pipe that is accommodated in the water inlet pipe is fixedly connected to the bottom of the circulating water tank through a positioning plate. The lower positioning shaft is sleeved in the lower positioning pipe and the two are rotatably engaged.

[0010] Furthermore, the rubber scraper has a rectangular frame structure and is connected to the rectangular frame by screws, and the outer wall of the circulating water tank is provided with a manhole near the bottom.

[0011] Furthermore, each set of the transfer pipes consists of at least three pipes, which are evenly distributed along the axial direction of the circulating water tank.

[0012] Furthermore, push plates are fixedly connected to both the left and right sides of the rectangular frame.

[0013] Furthermore, a flanged short pipe is fixedly connected to the bottom wall of the water outlet pipe, and the inner cavities of the two are connected.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, two sets of circumferentially symmetrical transfer pipes are provided on the outer peripheral wall of the circulating water tank. Then, a water pump is provided to supply water to the two sets of transfer pipes. The water pump draws water from the bottom of the circulating water tank. When the water is discharged from the circulating water tank, it will create a swirling effect. This swirling effect effectively washes the peripheral wall of the circulating water tank. Then, a rectangular frame is provided in the circulating water tank. The rectangular frame is rotatable. Rubber scrapers are provided on both sides of the rectangular frame. The rectangular frame will scrape the inner wall of the circulating water tank under the push of the swirling effect, thereby accelerating the dissolution and removal of dirt and improving the descaling efficiency.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a scale dissolving and cleaning device, including a cylindrical circulating water tank 1. A feeding pipe 11 and a water replenishment pipe 12 are fixedly installed on the top of the circulating water tank 1. The feeding pipe 11 is a channel for dispensing descaling agent, and the water replenishment pipe 12 is a channel for replenishing water into the circulating water tank 1. In use, the water replenishment pipe 12 can be connected to an external water pump through a pipeline. The water pump replenishes the circulating water tank 1 with clean water from an external water storage tank, so that the liquid level in the circulating water tank 1 rises to a position close to the top wall. A non-contact liquid level sensor can be installed on the top of the circulating water tank 1 to monitor the water level in the circulating water tank 1.

[0024] The outer peripheral wall of the circulating water tank 1 is fixedly connected to an outlet pipe 14 near the bottom, which is connected to the system pipeline. The inlet pipe at the top of the circulating water tank 1 is connected to the system pipeline. During use, the circulating water tank 1 is connected in series with matching control valves (manual or electric) on each pipeline (not shown in the figure).

[0025] In this technical solution, a left pipe 2 and a right pipe 3 are respectively installed on both sides of the circulating water tank 1. The left pipe 2 and the right pipe 3 are vertically arranged. Two sets of circumferentially symmetrical connecting pipes 4 are tangentially connected to the outer wall of the circulating water tank 1. That is, after one set of connecting pipes 4 rotates 180 degrees around the center of the circulating water tank 1, it will coincide with the other set of connecting pipes 4. The connecting pipes 4 are connected to the circulating water tank 1. When both sets of connecting pipes 4 simultaneously introduce water into the circulating water tank 1, the water in the circulating water tank 1 will swirl and circulate. The inner wall of the circulating water tank 1 is forcefully flushed. One end of each of the two sets of transfer pipes 4 is fixedly connected to the left pipe 2 and the right pipe 3, respectively. The left pipe 2 and the right pipe 3 are connected to their corresponding transfer pipes 4. A water inlet pipe 5 is fixedly connected to the bottom of the circulating water tank 1. The water inlet pipe 5 is connected to the circulating water tank 1. The bottom end of the water inlet pipe 5 is connected to the bottom of the left pipe 2 and the right pipe 3 through a transmission pipe 6. A water pump 7 is connected in series on the water inlet pipe 5. The water pump 7 is a variable frequency water pump and is connected to an external variable frequency controller during use. A drain pipe is fixedly connected to the bottom of the circulating water tank 1, and a drain valve is connected in series on the drain pipe.

[0026] The circulating water tank 1 contains a rectangular frame 8, which is rotatably connected to the circulating water tank 1. Rubber scrapers 9 are provided on both sides of the rectangular frame 8, with their outer sides abutting against the inner wall of the circulating water tank 1. The swirling water body causes the rectangular frame 8 to rotate, at which time the rubber scrapers 9 scrape the inner wall of the circulating water tank 1, thereby accelerating the rapid and reliable removal of dirt from the circulating water tank 1.

[0027] Specifically, an upper positioning shaft 81 is fixedly connected to the middle of the top of the rectangular frame 8, and an upper positioning tube 15 is fixedly connected to the top of the circulating water tank 1, which is sleeved outside the upper positioning shaft 81. The upper positioning tube 15 and the upper positioning shaft 81 are rotatably engaged. In specific implementation, a bearing and a sealing sleeve are installed between the upper positioning tube 15 and the upper positioning shaft 81.

[0028] Furthermore, a lower positioning shaft 82 is fixedly connected to the middle of the bottom end of the rectangular frame 8. The water inlet pipe 5 is located in the middle of the bottom of the circulating water tank 1. The bottom of the circulating water tank 1 is fixedly connected to a lower positioning pipe 13 that is housed in the water inlet pipe 5 through a positioning plate 16. There is a gap between the lower positioning pipe 13 and the inner wall of the water inlet pipe 5. The lower positioning shaft 82 is sleeved in the lower positioning pipe 13 and the two rotate in cooperation. In specific implementation, a bearing is installed between the lower positioning shaft 82 and the lower positioning pipe 13.

[0029] In this embodiment, the rubber scraper 9 is a rectangular frame structure and is connected to the rectangular frame 8 by screws 101. The rectangular frame 8 has threaded holes on both sides that are compatible with the screws 101. This arrangement facilitates the replacement of the rubber scraper 9. The outer wall of the circulating water tank 1 is provided with a manhole 102 near the bottom. The manhole 102 is a flange structure, and the opening of the manhole 102 is sealed by a flange blind plate and bolts. After the manhole 102 is opened, maintenance personnel can enter and exit the circulating water tank 1.

[0030] In this embodiment, each set of connecting pipes 4 consists of at least three pipes, which are evenly distributed along the axial direction of the circulating water tank 1, thereby increasing the speed of the water swirling within the circulating water tank 1. Furthermore, push plates 83 are fixedly connected to both the left and right sides of the rectangular frame 8. Under the push of the high-swirling water, the push plates 83 drive the rectangular frame 8 to rotate at high speed, thereby increasing the scraping force of the rubber scraper 9 on the dirt.

[0031] In this embodiment, a flange short pipe 141 is fixedly connected to the bottom wall of the water outlet pipe 14 and the inner cavities of the two are connected. The function of the flange short pipe 141 is to install the connecting pipe of the water quality detection component (such as a pH sensor). In specific implementation, the water quality detection component is installed on a flange plate, and then the flange plate and the flange short pipe 141 are fastened together with bolts. The probe of the water quality detection component is located inside the water outlet pipe 14, which facilitates water quality monitoring.

[0032] Working principle: When cleaning the inner wall of the circulating water tank 1 regularly, close the valves on the inlet and outlet pipes 14 connected to the circulating water tank 1. Add the descaling agent into the circulating water tank 1 through the feed pipe 11. Then, inject clean water into the circulating water tank 1 through the water supply pipe 12, so that the water level is close to the top wall of the circulating water tank 1. Then, start the water pump 7. The mixed solution in the circulating water tank 1 enters the water inlet pipe 5, then enters the left pipe 2 and right pipe 3 through the transmission pipe 6, and finally enters the circulating water tank 1 through the transfer pipe 4. At this time, the water in the circulating water tank 1 will be impacted and swirled rapidly. The mixed agent washes the inner wall of the circulating water tank 1. The swirling agent pushes the rectangular frame 8 to rotate through the push plate 83. The rubber scraper 9 scrapes the dirt on the inner wall of the circulating water tank 1, accelerating the removal of dirt. At the same time, the mixed agent and the unremoved agent come into rapid contact, accelerating dissolution. After cleaning, open the drain valve at the bottom of the circulating water tank 1 to discharge the sewage, realizing the function of dissolving and cleaning dirt.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
