Description

Technical Field

[0001] The utility model relates to the technical field of filtering and sand removal, in particular to a hot spring water filtering and sand removal device. Background Art

[0002] As a unique natural resource, hot springs are loved by more and more people because of their functions of recuperation and relaxation, and have gradually become a hot spot in the tourism and health industries. High-quality hot spring water is a key factor in attracting tourists and ensuring their health and safety. Therefore, in the development and utilization of hot spring resources, water quality treatment issues cannot be ignored. Hot spring pools are usually built near hot spring water sources. Since hot spring water is rich in minerals and may also contain more sand particles, in order to improve the customer's experience and comfort, the hot spring water must be purified by a sand removal and filtration system before it is injected into the pool. Especially in the summer flood season, rainwater may carry silt and other pollutants into the hot spring water source, which not only seriously affects the quality of hot spring water, but also may clog pipes and equipment, thereby increasing maintenance costs and operational difficulties. In addition, the self-cleaning function of the sand removal and filtration device is also a key link in ensuring water quality. An effective self-cleaning mechanism can reduce the maintenance frequency of the equipment and extend its service life, while ensuring the continuous cleanliness and safety of the hot spring water, providing tourists with a healthier and more comfortable hot spring experience.

[0003] At present, the existing sand removal and filtration devices for hot spring pool construction on the market have the following shortcomings when dealing with the large amount of silt and impurities brought by the flood season: the device lacks the ability of multi-stage filtration, resulting in limited filtration effect; at the same time, the sand and gravel generated during the filtration process easily accumulate on the filter plate or filter screen, forming blockage, which not only weakens the filtration efficiency but also increases the difficulty of maintenance; in addition, the self-cleaning function of the existing filtration device also has defects and relies heavily on manual cleaning, which is not only inefficient, but may not be able to completely remove impurities. In summary, the sand removal and filtration devices currently used in many hot spring pool buildings have not yet met the high efficiency and automation requirements in practical applications.

[0004] Therefore, it is an urgent problem to provide a sand removal and filtering device for hot spring water that can filter and remove sand in multiple stages and can be self-cleaning. Utility Model Content

[0025] (3) The sedimentation tank of the device is of a U-shaped tube structure. When the water flows through the bottom of the U-shaped tube, the sediment will automatically deposit at the bottom of the U-shaped tube. The filter screen inside the sedimentation tank prevents part of the sediment from being carried away by the excessive water flow, resulting in pipeline blockage.

[0026] (4) The first filter box and the second filter box of the device are respectively provided with self-cleaning devices. The first filter box filters out water through the through holes on the thread, transports large-particle sand and gravel to the baffle and then discharges them. The second filter box diverts a part of the already filtered hot spring water for cleaning the filter plate to prevent blockage, improving resource utilization rate and saving costs.

[0027] (5) The device has a simple structure and is easy to operate. While improving the filtration efficiency, it also prevents pipeline blockage, reducing the maintenance cost and operation difficulty. Description of the Drawings

[0031] Embodiment 1

[0032] Combined with Figure 1 , a sand filtering and removing device for hot spring water, comprising a first filter tank 1, a sedimentation tank 2, a second filter tank 3 and an electric control component;

[0033] A filter cartridge 105, a baffle 104 and a cleaning component are installed inside the first filter tank 1.

The baffle 104 is penetrated by the spiral blade 108. The baffle 104 inclines towards the first slag discharge pipe 101, with an inclination angle of 15°; the first water inlet pipe 102 is located inside the filter cartridge 105, and the first drain pipe 103 is located below the baffle 104.

[0036] The sedimentation tank 2 is of a U-shaped tube structure. Inside the sedimentation tank 2, a U-shaped groove 201 and a filter screen 203 are arranged in sequence along the water flow direction. The U-shaped groove 201 is installed at the bottom of the sedimentation tank 2. The U-shaped groove 201 is movably connected to the sedimentation tank 2 through a pin shaft 202. The U-shaped groove 201 is in contact with the pipe wall of the sedimentation tank 2. A slag discharge hopper 205 is provided outside the sedimentation tank 2. The slag discharge hopper 205 is located below the U-shaped groove 201. The slag discharge hopper 205 is installed on the sedimentation tank 2 through a connecting column 204.

[0037] On the second filter box 3, a second water inlet pipe 301, a second slag discharge pipe 302, and a second drain pipe 303 are sequentially arranged in the water flow direction. There are multiple second slag discharge pipes 302, and a second valve 3021 is provided at the second slag discharge pipe 302. Inside the second filter box 3, a filter plate 304 is installed. There are multiple filter plates 304. The filter plates 304 are inclined, with an inclination angle of 15°, and the lowest point is located at the second slag discharge pipe 302. Inside the second filter box 3, a spray pipe 404 is installed. Multiple spray heads 405 are installed on the spray pipe 404, and the spray heads 405 are arranged above the filter plates 304.

[0038] The first drain pipe 103 is connected to the water inlet of the settler 2 through a first pipeline 501. The second water inlet pipe 301 is connected to the water outlet of the settler 2 through a second pipeline 502. The second drain pipe 303 is connected to the water inlet of the water pump 4. The water outlet of the water pump 4 is connected to a tee 402 through a third pipeline 401. The spray pipe 404 is connected to the outlet of the tee 402. The water outlet pipe 403 is connected to the outlet of the tee 402.

[0039] The electric control component includes a power supply 601, a controller 602, and an operation panel 603. The operation panel 603 is installed on the first filter box 1. The power supply 601 is electrically connected to the motor 106, the water pump 4, the controller 602, and the operation panel 603 respectively. The controller 602 is electrically connected to the motor 106, the water pump 4, and the operation panel 603 respectively.

[0040] The operating principle of this device is as follows:

[0041] The untreated hot spring water enters the first filter box 1 from the water inlet pipe 102. After the water body is preliminarily filtered by the filter cylinder 105, the filter residue (large - particle sand or other pollutants, etc.) is left in the filter cylinder 105. At this time, the motor 106 is started. The motor 106 drives the spiral blade 108 to rotate. Because the spiral blade 108 has through - holes, the water body flows out from the through - holes. The filter residue is brought to the baffle 104 by the spiral blade 108. The filter residue is thrown onto the baffle 104 due to centrifugal force. Since the baffle 104 is in an inclined state, the filter residue rolls to the first slag discharge pipe 101 and is discharged.

[0042] The water body flows out from the first drain pipe 103, passes through the first pipeline 501, and flows into the settler 2. Since the settler 2 is a U - shaped pipe structure, fine sand and gravel (small - particle sand or sediment, etc.) will naturally settle in the U - shaped groove 201 when the water body flows through the bottom of the U - shaped pipe. At this time, the U - shaped groove 201 is rotated to discharge the fine sand and gravel immersed in the groove. The filter screen 203 prevents part of the fine sand and gravel from being carried out of the settler 2 due to excessive water flow.

[0043] The water body sequentially passes through pipeline two 502 and water inlet pipe two 301 and enters into filter box two 2. Multiple filter plates 304 are provided in filter box 2. The filter plates 304 remove harmful substances in the water (such as organic matters like microorganisms, harmful bacteria, ammonia nitrogen, etc.) and fine particles. The purified water body flows into water pump 4 through drain pipe two 303. After being pressurized by water pump 4, a part of it flows out through water outlet pipe 403, and the other part re-enters filter box two 2 through spray pipe 404 and is sprayed out through spray head 405 for cleaning filter plates 304 to prevent the filter plates 304 from being blocked.

[0044] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but rather will be accorded the widest scope consistent with the principles and novel features disclosed herein.
