Description

Technical Field

[0001] This utility model relates to the field of water treatment technology for sun dryers, and specifically to a water circulation device for sun dryers. Background Technology

[0002] Traditional sun-drying machines use a self-disassembling and self-installation system for water tanks and do not have external water pipes, making it impossible to automatically change and replenish the water tank. On the other hand, sun-drying machines with automatic water changing capabilities lack multi-stage filtration mechanisms, and impurities in the water can easily clog pipes or affect the quality of the dried materials. Inaccurate water level control can also easily lead to overflow or insufficient water supply. Utility Model Content

[0003] To address these issues, this invention provides a water circulation device for a sun dryer, which solves the problems of not being able to automatically change and replenish water, lacking a filtration mechanism, and having inaccurate water level control.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water tank installed inside a sun dryer, the top of which is provided with an opening and closing mechanism and a water supply hole. An upper water float valve is installed at the opening and closing mechanism, wherein the inlet of the upper water float valve is located outside the water tank, and the outlet of the upper water float valve is located inside the water tank. The inlet and outlet of the upper water float valve are L-shaped, with the inlet facing upwards. The upper water float valve is connected to an inlet pipe and an outlet pipe, and the inlet pipe and the outlet pipe are threadedly connected to the magnetic float valve.

[0005] Preferably, the upper water float valve is equipped with an adsorption device, and the adsorption end of the adsorption device is positioned relative to the water outlet end of the water outlet.

[0006] Preferably, the adsorption device includes a connecting rod and a vacuum suction cup, the vacuum suction cup being disposed at one end of the connecting rod, and the vacuum suction cup being used to adsorb onto the inner wall of the water tank to fix the upper water float valve.

[0007] Preferably, a filter screen is installed inside the water outlet pipe.

[0008] Preferably, the filter screen includes a first filter screen, a second filter screen, and a third filter screen, which are arranged sequentially in the direction of water outlet.

[0009] Preferably, the first filter screen is a PP cotton filter element, the second filter screen is a granular activated carbon filter element, and the third filter screen is an ultrafiltration membrane filter element.

[0010] Preferably, the opening and closing mechanism is symmetrically arranged with respect to the water supply hole.

[0011] Preferably, the opening and closing mechanism is provided with a sealing plate and a slide rail, and two sets of both the sealing plate and the slide rail are provided.

[0012] Preferably, the two ends of the sealing plate are slidably connected to the slide rail. The two sets of sealing plates can be opened by sliding in opposite directions for removing the upper water float valve, and the two sets of sealing plates can be closed by sliding in the same direction for fixing the upper water float valve.

[0013] Preferably, a locking device is provided above the surface of the sealing plate.

[0014] The application employs the above technical solution and has at least the following beneficial effects:

[0015] The reduction in the purchase of bottled tertiary water saves costs and reduces the handling by testing personnel. Testing personnel no longer need to periodically add water, solving the problem of refilling water periodically, improving work efficiency, and enhancing water quality. The L-shaped float valve design directs the water inlet upwards, reducing disturbance to the water flow in the tank and improving circulation stability. The combination of the vacuum suction cup and connecting rod allows for tool-free quick disassembly and assembly of the float valve, significantly shortening maintenance time. Three-stage progressive filtration ensures the water quality in the tank. The double-sealing plate sliding + locking structure balances ease of operation with reliable sealing, reducing evaporation loss and external contamination.

[0016] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] A specific embodiment of this utility model provides a water circulation device for a sun tanner, combined with the attached... Figure 1-3 As shown, it mainly includes a water tank 1, a float valve 3, an adsorption device, a three-stage filtration assembly, an opening and closing mechanism, and necessary piping systems. The water tank 1 is made of 304 stainless steel or food-grade PP injection molding, and its shape is rectangular or cylindrical. The capacity can be selected between 5 L and 100 L depending on the model of the sun dryer. A water supply hole 2 is provided on the top side of the water tank 1. A symmetrical opening and closing mechanism and a water inlet float valve 3 are provided at the water supply hole 2. The water inlet float valve 3 is an L-shaped quick-install structure, consisting of a valve body, float, connecting rod, sealing gasket, inlet 4, and outlet 5. The valve body is made of nickel-plated brass or PPSU engineering plastic, which can be high-strength, corrosion-resistant, and high-temperature resistant, thus improving its service life. The float is made of hollow PP or NBR foam material. The inlet 4 extends vertically upward from the top plate of the water tank 1 and is connected to the water inlet pipe 6 through external threads. The outlet 5 extends horizontally into the interior of the water tank 1, forming an L-shaped layout with the inlet 4 at a 90° angle. This layout allows the water to enter the valve body vertically and then flow out horizontally after a right-angle turn, effectively reducing water flow impact and reducing the generation of air bubbles.

[0024] Specifically, the adsorption device consists of a connecting rod 8 and a vacuum suction cup 9. The connecting rod 8 is made of ABS or PC injection molding, with a length of 30 mm to 50 mm. One end is fixedly connected to the valve body of the upper water float valve 3, and the other end is fixedly equipped with the vacuum suction cup 9, which is made of nitrile rubber or silicone. During installation, the upper water float valve 3 is first placed inside the upper part of the water tank 1 and adjusted to a suitable angle. Then, the vacuum suction cup 9 is pressed to firmly adhere to the inner wall of the water tank 1, forming a secondary fixation to prevent the valve body from loosening due to vibration or water pressure pulses.

[0025] Specifically, the outlet pipe 7 is equipped with a first filter screen 10, a second filter screen 11, and a third filter screen 12 in sequence along the water flow direction. Each filter element is encapsulated in a PP shell and sealed with hot plates at both ends, allowing for complete insertion and removal for replacement. The first filter screen 10 uses a PP cotton melt-blown filter element, which can effectively intercept rust, sediment, and colloids. The second filter screen 11 uses coconut shell granular activated carbon, which can effectively remove residual chlorine, odors, and some organic matter. The third filter screen 12 uses a hollow fiber ultrafiltration membrane, which can achieve a bacterial removal rate of up to 99.9%.

[0026] Specifically, at the opening and closing mechanism at the top of the water tank 1, two sets of slide rails 14 are provided at opposite ends. The two ends of the two sets of sealing plates 13 are slidably connected to the slide rails 14 respectively. Each set of sealing plates 13 is provided with a semi-circular notch. After the two sets of sealing plates 13 are spliced ​​together, a circular notch is provided. This circular notch is used for fixing and placing the upper float valve 3. After the two sets of sealing plates 13 slide in opposite directions, they can be opened for the installation or disassembly and maintenance of the upper float valve 3. After the two sets of sealing plates 13 slide in opposite directions, they can be closed for fixing the upper float valve 3 and sealing the water tank 1. A locking device 15 is provided above the surface of the sealing plate 13. When the sealing plate 13 is closed, the locking device 15 restricts the sliding of the sealing plate 13. When the locking device 15 is opened, the sliding of the sealing plate 13 can be realized.

[0027] The working principle of the device in this embodiment:

[0028] When the water level in water tank 1 is lower than the set lower limit, the float ball sinks, the water inlet float valve 3 opens, and the tap water or ultrapure water machine supply flows through the inlet pipe 6 → inlet 4 → valve body → outlet 5 → filter screen → water tank 1, achieving rapid filtration and water replenishment; when the water level reaches the upper limit, the float ball rises, the valve closes, and water replenishment stops.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
