Description

Technical Field

[0001] This utility model relates to the technical field of water filtration devices, and in particular to a water purification and filtration device. Background Technology

[0002] The background technology of fishpond water purification and filtration devices mainly addresses the problem of severe water pollution in fishponds caused by high stocking density, overfeeding, and poor water circulation. The water contains a large number of harmful substances, such as ammonia nitrogen, nitrite, and planktonic matter, which affect fish growth and the aquatic ecological environment. Therefore, using high-efficiency filtration devices to purify the water, maintain water quality, and promote the healthy growth of fish has become a technical problem that urgently needs to be solved in the aquaculture industry.

[0003] However, in actual use, the following shortcomings still exist. For example, existing water purification and filtration devices cannot flush the filter layer to remove impurities and restore filtration performance. As the filtration time increases, impurities such as suspended solids, organic matter, and microbial residues in the water will gradually accumulate in the filter layer, causing the pores of the filter layer to become blocked. This increases the resistance to water flow and significantly reduces filtration efficiency. Since the filtration performance cannot be restored by flushing, the filter material may need to be replaced more frequently, increasing material costs and labor maintenance costs. The blocked filter layer will also increase water flow resistance.

[0004] Therefore, this utility model proposes a water purification and filtration device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose a water purification and filtration device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water purification and filtration device, comprising a tank and a tank cover disposed on the tank, and further comprising:

[0007] A purification and filtration assembly includes an installation rod disposed inside a tank, a filter screen disposed on the installation rod, a ceramic filter element disposed on the installation rod near the top of the filter screen, a gradient hole being formed on the ceramic filter element, and activated carbon disposed on the installation rod near the top of the ceramic filter element.

[0008] A backwashing assembly includes a protective shell connected to a tank body, a rotating shaft rotatably connected to the protective shell, a rotating seat connected to the rotating shaft, a rotating frame mounted on the rotating seat, a nozzle mounted on the rotating frame, a water tank mounted on the tank cover, a water pump mounted on the water tank, a water pipe connected to the output end of the water pump, and the other end of the water pipe connected to the nozzle.

[0009] Furthermore, a limiting ring is connected inside the tank, and the filter screen is disposed on the limiting ring.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the limiting ring is fixed in the tank to provide stable support for the filter screen. When the water flows into the tank from the inlet, it first passes through the filter screen, and large particles of impurities are intercepted. The limiting ring and the mounting rod ensure that the filter screen is in a stable position, prevent the water flow impact from causing displacement, and ensure the stability of the filtration effect. The filter screen can be removed for cleaning or replacement periodically, making the operation convenient.

[0011] Furthermore, a water inlet is provided on the side of the tank near the bottom, and a water outlet is provided on the side of the tank near the top.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the water inlet is located at the bottom of the tank, so that the water flows from bottom to top, fully passes through each filter layer, and the purified water flows out from the top outlet.

[0013] Furthermore, an impurity cleaning pipe is provided at the bottom of the tank, and a valve is provided on the impurity cleaning pipe.

[0014] The beneficial effects of adopting the above-mentioned further solution are: as filtration proceeds, impurities settle to the bottom of the tank, and by opening the valve, the impurities can be discharged through the impurity cleaning pipe, thus achieving convenient cleaning of impurities and avoiding affecting the filtration effect.

[0015] Furthermore, a first drive motor is installed inside the protective shell, the output end of the first drive motor is connected to a first drive wheel, a first belt is provided on the first drive wheel, a second drive wheel is provided on the first belt, and the rotating shaft is connected to the second drive wheel.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: After the first drive motor starts, it drives the first drive wheel to rotate, and transmits power to the second drive wheel through the first belt, causing the rotating shaft to rotate. The rotating shaft drives the rotating seat and rotating frame to rotate, thereby causing the nozzle to rotate around the shaft, so that the nozzle can perform multi-angle rinsing of the filter screen and ceramic filter element, improving the backwashing effect.

[0017] Furthermore, a second drive motor is installed inside the protective shell on the side near the bottom of the first drive motor. The output end of the second drive motor is connected to a third drive wheel. A second belt is provided on the third drive wheel, and a fourth drive wheel is provided on the second belt.

[0018] The beneficial effects of adopting the above-mentioned further scheme are: the second drive motor drives the third drive wheel to rotate, and the second belt drives the fourth drive wheel to rotate. The first bevel gear on the fourth drive wheel meshes with the second bevel gear, so that the rotating frame can swing up and down while rotating. The combined motion makes the spray head have a wider rinsing range and enhances the backwashing effect.

[0019] Furthermore, a first bevel gear is connected to the fourth transmission wheel, a second bevel gear meshes with the first bevel gear, and the rotating frame is connected to the second bevel gear.

[0020] The beneficial effects of adopting the above-mentioned further solution are as follows: when backwashing is required, the water pump draws water from the water tank and delivers it to the nozzle through the water pipe. The first drive motor and the second drive motor work simultaneously, enabling the nozzle to achieve a combined rotation and oscillation motion, which thoroughly washes the filter layer. The reverse water flow washes off the attached impurities, which are then discharged with the water flow through the impurity cleaning pipe, restoring the performance of the filter components.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, when water requiring purification and filtration flows into the tank, the purification and filtration assembly begins to work. The water first passes through the filter screen to intercept large particles of impurities, then through the ceramic filter element, whose gradient pores filter suspended solids of different particle sizes in stages, and finally through activated carbon to adsorb organic matter, pigments, and odors, thus completing water purification. With use, impurities will accumulate on the filter screen and ceramic filter element, affecting the filtration effect. At this time, the backwashing assembly is activated, and the water pump draws water from the tank and delivers it to the nozzle through the water pipe. The rotating shaft drives the rotating seat and rotating frame to rotate, allowing the nozzle to rotate in multiple directions. The nozzle sprays water to rinse the filter layer, wash away impurities, and restore the filtration performance. Attached Figure Description

Detailed Implementation

[0032] 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.

[0033] like Figures 1-5 As shown, this embodiment provides a technical solution: a water purification and filtration device, including a tank 1 and a tank cover 2 disposed on the tank 1, and further including:

[0034] Purification and filtration assembly 3 includes an installation rod 31 disposed inside the tank 1, a filter screen 32 disposed on the installation rod 31, a ceramic filter element 33 disposed on the side of the installation rod 31 near the top of the filter screen 32, a gradient hole 34 opened on the ceramic filter element 33, and activated carbon 35 disposed on the side of the installation rod 31 near the top of the ceramic filter element 33.

[0035] Backwash assembly 4 includes a protective shell 41 connected to the tank body 1, a rotating shaft 46 rotatably connected to the protective shell 41, a rotating seat 47 connected to the rotating shaft 46, a rotating frame 48 mounted on the rotating seat 47, and a spray nozzle 49 mounted on the rotating frame 48. A water tank 410 is mounted on the tank cover 2, and a water pump 411 is installed on the water tank 410. The output end of the water pump 411 is connected to a water pipe 412, and the other end of the water pipe 412 is connected to the spray nozzle 49. When the water to be purified and filtered flows into the tank body 1, the purification and filtration assembly 3 starts to work. The water first passes through the filter screen 32 to intercept large particles of impurities. Next, the water passes through the ceramic filter element 33, whose gradient holes 34 filter suspended solids of different sizes in stages. Finally, the activated carbon 35 adsorbs organic matter, pigments and odors to complete the water purification. With use, impurities will adhere to the filter screen 32 and the ceramic filter element 33, affecting the filtration effect. At this time, the backwashing component 4 is started, and the water pump 411 draws water out of the water tank 410 and delivers it to the nozzle 49 through the water pipe 412. The rotating shaft 46 drives the rotating seat 47 and the rotating frame 48 to rotate, so that the nozzle 49 can rotate in multiple directions. The nozzle 49 sprays water to wash the filter layer, wash away impurities and restore the filtration performance.

[0036] The above solutions also have the problem that, when the filter layer needs to be rinsed, the combined motion of the automatic adjustment nozzle 49's rotation and oscillation cannot be satisfied. Figures 1-2 As shown: A limiting ring 36 is connected inside the tank body 1, and the filter screen 32 is set on the limiting ring 36. The limiting ring 36 is fixed inside the tank body 1, providing stable support for the filter screen 32. When water flows into the tank body 1 from the inlet 37, it first passes through the filter screen 32, where large particles of impurities are intercepted. The limiting ring 36 and the mounting rod 31 ensure that the filter screen 32 is in a stable position, preventing displacement caused by water flow impact and ensuring the stability of the filtration effect. The filter screen 32 can be removed for cleaning or replacement periodically, making operation convenient. A side of the tank body 1 near the bottom is provided with... The tank body 1 has an inlet 37 and an outlet 38 located on the side near the top. The inlet 37 is located at the bottom of the tank body 1, allowing water to flow from bottom to top and fully pass through each filter layer. The purified water flows out from the top outlet 38. The bottom of the tank body 1 is equipped with an impurity cleaning pipe 39 and a valve 310. As filtration proceeds, impurities settle to the bottom of the tank body 1. By opening the valve 310, the impurities can be discharged through the impurity cleaning pipe 39, achieving convenient cleaning of impurities and avoiding affecting the filtration effect.

[0037] like Figure 5As shown, a first drive motor 42 is installed inside the protective housing 41. The output end of the first drive motor 42 is connected to a first drive wheel 43. A first belt 44 is installed on the first drive wheel 43, and a second drive wheel 45 is installed on the first belt 44. A rotating shaft 46 is connected to the second drive wheel 45. After the first drive motor 42 is started, it drives the first drive wheel 43 to rotate, and transmits power to the second drive wheel 45 through the first belt 44, causing the rotating shaft 46 to rotate. The rotating shaft 46 drives the rotating seat 47 and the rotating frame 48 to rotate, thereby causing the nozzle 49 to rotate around the shaft, so that the nozzle 49 can perform multi-angle washing of the filter screen 32 and the ceramic filter element 33, improving the backwashing effect. A second drive motor 413 is installed inside the protective housing 41 near the bottom of the first drive motor 42. The output end of the second drive motor 413 is connected to a third drive wheel 414. A second belt 415 is installed on the third drive wheel 414, and a fourth drive wheel is installed on the second belt 415. 416. The second drive motor 413 drives the third drive wheel 414 to rotate, which in turn drives the fourth drive wheel 416 to rotate via the second belt 415. The first bevel gear 417 on the fourth drive wheel 416 meshes with the second bevel gear 418, causing the rotating frame 48 to swing up and down while rotating. This combined motion makes the spray head 49 have a wider rinsing range and enhances the backwashing effect. The first bevel gear 417 is connected to the fourth drive wheel 416, and the second bevel gear 418 meshes with the first bevel gear 417. The rotating frame 48 is connected to the second bevel gear 418. When backwashing is required, the water pump 411 draws water from the water tank 410 and delivers it to the spray head 49 through the water pipe 412. The first drive motor 42 and the second drive motor 413 work simultaneously, enabling the spray head 49 to achieve a combined rotation and swing motion, which thoroughly rinses the filter layer. The reverse water flow washes off the attached impurities, which are then discharged through the impurity cleaning pipe 39 with the water flow, restoring the performance of the filter assembly.

[0038] Working principle:

[0039] like Figures 1-5As shown, when the water requiring purification and filtration flows in from the inlet 37 at the bottom of the tank 1, the purification and filtration process is immediately initiated. The water first contacts the filter screen 32, which is set on the limiting ring 36 inside the tank 1. The filter screen 32, with its mesh size, intercepts large particles of impurities. The limiting ring 36 and the mounting rod 31 work together to ensure the stability of the filter layer and prevent displacement caused by water flow impact. Next, the water flows into the ceramic filter element 33, where the gradient pores 34 on its surface play a key role. The pore size decreases from the inlet to the outlet, achieving graded filtration of suspended solids of different particle sizes, further removing tiny particles, while allowing beneficial microorganisms and nutrients to pass through smoothly. Finally, the water flows through the activated carbon 35, whose strong adsorption capacity adsorbs organic matter, pigments, and odors in the water. After being processed by these three layers of purification and filtration components 3, the purified water flows out from the outlet 38 at the top of the tank 1. As the device continues to operate, impurities will adhere to the surfaces of the filter screen 32 and the ceramic filter element 33, affecting the filtration effect. At this time, the backwashing component 4 is activated, and the water tank on the tank cover 2 is activated. Water in 410 is pumped out by water pump 411 and transported to nozzle 49 through water pipe 412. At the same time, the first drive motor 42 and the second drive motor 413 inside the protective shell 41 operate synchronously. The first drive motor 42 drives the first drive wheel 43 to rotate, and transmits the power to the second drive wheel 45 through the first belt 44, causing the rotating shaft 46 to rotate, which in turn drives the rotating seat 47 and the rotating frame 48 to rotate around the axis. The second drive motor 413 drives the third drive wheel 414 to rotate, and drives the fourth drive wheel 416 through the second belt 415. The first bevel gear 417 on the fourth drive wheel 416 meshes with the second bevel gear 418, causing the rotating frame 48 to swing up and down while rotating. Under this combined motion, the nozzle 49 performs all-round and multi-angle rinsing of the filter screen 32 and the ceramic filter element 33. The reverse water flow washes away the impurities. The washed-off impurities are discharged with the water flow through the impurity cleaning pipe 39 at the bottom of the tank 1. The valve 310 can be opened to discharge them, thereby restoring the performance of the purification filter component 3 and ensuring the continuous and efficient operation of the device.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
