Description

Technical Field

[0001] This utility model belongs to the technical field of water purification equipment, and in particular relates to a perlite filter for swimming pools. Background Technology

[0002] Perlite filtration equipment is a device that uses perlite as a filter medium for water treatment or air purification. It filters and adsorbs suspended solids, impurities, bacteria and other pollutants in water or air through the porous structure and surface adsorption properties of perlite, thereby achieving a purification effect.

[0003] Perlite filter media typically has a small particle size (commonly ranging from 0.5 to 2 mm) and a fine pore structure. If the wastewater contains sand, stones, fibrous impurities, large flocs, etc. with a particle size greater than 1 mm, they will directly clog the pores on the surface of the filter layer, causing the filtration pressure differential to rise rapidly, the backwashing frequency to surge, and even causing the filter layer to clump together, significantly shortening the service life of the filter media.

[0029] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figure 1-6 As shown, a perlite filter for swimming pools includes a filter tank 1, an inlet pipe 2, an outlet pipe 3, and a pretreatment mechanism. The filter tank 1 is a conventional perlite filter tank with multiple perlite filter plates inside. The inlet pipe 2 is fixed to the top of the filter tank 1 and is used to inject the liquid to be treated into the filter tank 1. The outlet pipe 3 is fixed to the side wall of the filter tank 1 and is used to discharge the treated liquid.

[0031] Specifically, the pretreatment mechanism includes a mounting plate 72, a connecting pipe 73, a fixing frame 75, and a filter screen 76. The mounting plate 72 is fixed to the end of the inlet pipe 2 and has an insertion slot for the fixing frame 75 to be inserted. A through hole is located in the middle of the mounting plate 72. One end of the connecting pipe 73 is fixed to the mounting plate 72. The fixing frame 75 is detachably connected to the mounting plate 72 and can be inserted into the insertion slot. The filter screen 76 is detachably fixed inside the mounting plate 72. Thus, the perlite filter for the swimming pool is connected to the water to be treated through the inlet pipe 2, and the water is pretreated... The water flows into the connecting pipe 73 of the treatment unit, where large particles such as sand and fibers are intercepted by the filter screen 76 inside the fixed frame 75. The water then enters the filter tank 1 through the through hole in the middle of the mounting plate 72 for perlite filtration. The fixed frame 75 can be detached and installed through the insertion slot of the mounting plate 72. This structure can effectively prevent large particles of impurities from clogging the perlite filter layer, prevent the filter layer from caking, extend the service life of the filter media, and reduce the backwashing frequency. At the same time, the detachable design also provides convenience for cleaning and replacing the filter screen 76, improving the efficiency of equipment operation and maintenance.

[0032] As a preferred embodiment, the pretreatment mechanism also includes a locking rod 77, a baffle 78, and a tension spring 79. The locking rod 77 is symmetrically arranged on both sides of the mounting plate 72. The mounting plate 72 has a sliding hole for the locking rod 77 to slide into. One end of the locking rod 77 extends into the insertion groove, and the fixing frame 75 has a locking hole that cooperates with the locking rod 77. The baffle 78 is fixed to the end of the locking rod 77. The tension spring 79 is sleeved on the locking rod 77, with one end fixed to the baffle 78 and the other end fixed to the mounting plate 72. When installing the fixing frame 75, the locking rod 77 extends into the locking hole of the fixing frame 75 under the action of the tension spring 79 to achieve a stable connection. When disassembling, pulling the baffle 78 outward will disengage the locking rod 77 from the locking hole. This structure achieves automatic locking of the fixing frame 75 by means of spring elasticity, without the need for additional tools, making operation convenient and efficient. At the same time, the symmetrically arranged locking rods 77 ensure that the fixing frame 75 is subjected to balanced force, avoiding equipment vibration that could cause the fixing frame 75 to loosen, and ensuring stable operation of the filter structure.

[0033] In other embodiments, the end of the fixing frame 75 is provided with an arc-shaped curved surface. When the fixing frame 75 is inserted into the insertion slot, the end of the locking rod 77 contacts the arc-shaped curved surface. When the fixing frame 75 is inserted into the insertion slot, its end arc-shaped curved surface contacts the locking rod 77 and generates a lateral thrust, forcing the locking rod 77 to compress the tension spring 79 and move. After the fixing frame 75 is inserted into place and the locking hole is aligned with the locking rod 77, the locking rod 77 resets and locks into the locking hole. The guiding effect of the arc-shaped curved surface can simplify the installation process of the fixing frame 75, eliminate the need for manual operation of the locking rod 77, and also avoid hard collisions between components, thus extending the service life of the structure.

[0034] In other embodiments, a ball bearing 771 is rotatably provided at the end of the locking rod 77. The ball bearing 771 rotatably provided at the end of the locking rod 77 can convert the sliding friction between the two into rolling friction when the fixing frame 75 is inserted or pulled out, which significantly reduces the contact resistance. This reduces the frictional loss between the locking rod 77 and the fixing frame 75, extends their service life, and makes the installation and removal of the fixing frame 75 smoother, reduces the operating force, and improves the user experience.

[0035] In other embodiments, a sealing strip 81 is fixed on the outer wall of the fixed frame 75, and the insertion groove is provided with a sealing groove that cooperates with the sealing strip 81. After the sealing strip 81 on the fixed frame 75 is inserted into the insertion groove, it is precisely embedded in the sealing groove, and the gap between the fixed frame 75 and the insertion groove is filled by the elastic deformation of the sealing strip 81.

[0036] In other embodiments, the fixing frame 75 is provided with a mounting groove for inserting the filter screen 76. The fixing frame 75 is provided with a plurality of fastening bolts 761. The ends of the fastening bolts 761 abut against the filter screen 76. The filter screen 76 can be inserted into the mounting groove of the fixing frame 75. Tightening the fastening bolts 761 on the fixing frame 75 can fix the filter screen 76 by the bolt ends abutting against it. Loosening the bolts can replace the filter screen.

[0037] In other embodiments, a sealing cap 82 is fitted onto the fixing frame 75, and a sealing plate 83 is provided inside the sealing cap 82. The sealing plate 83 can be inserted into the mounting groove. When the sealing cap 82 is fitted onto the fixing frame 75, the sealing plate 83 is inserted into the mounting groove of the fixing frame 75, forming a seal at the opening of the mounting groove. Multiple elastic protrusions 84 are provided on both sides of the sealing plate 83. An elastic clip 85 is provided on the side wall of the sealing cap 82. The fixing frame 75 is provided with a protrusion 86 that cooperates with the elastic clip 85. When the sealing cap 82 is fitted, the elastic clip 85 on its side wall is deformed by the pressure of the outer wall of the fixing frame 75. When it moves to the position of the protrusion 86, it resets and engages to achieve fixation. When disassembling, pressing the clip can disengage it from the protrusion 86. This structure allows for quick disassembly and assembly of the sealing cap 82 without additional tools, improving maintenance convenience.

[0038] In other embodiments, the filter tank 1 is provided with multiple support feet 91. The bottom of the support feet 91 is provided with a main shock-absorbing layer 92, a buffer transition layer 93, and an anti-slip contact layer 94 in sequence. The main shock-absorbing layer 92 is made of nitrile rubber, the buffer transition layer 93 is made of polyurethane foam, and the anti-slip contact layer 94 is made of silicone with diamond-shaped anti-slip texture on the surface.
