Description

TECHNICAL FIELD

[0001] The utility model relates to the field of aquaculture equipment, especially a sand filter with swing filter screen. BACKGROUND

[0002] Sand filters have a wide range of applications in the aquaculture industry, mainly for water purification and filtration, helping to maintain water cleanliness and create an environment conducive to the growth of aquatic organisms. Water quality management in aquaculture is a key factor in ensuring healthy and high-yield cultivation. Organic matter, suspended solids and impurities in water can affect the cultivation environment, leading to water pollution and health problems for aquatic animals such as fish and shrimp. Sand filters can effectively remove suspended particles, sediments, plankton and some larger organic matter from water through physical filtration, thereby maintaining water cleanliness. Sand filters can remove impurities from water, reducing the pollution load of water bodies and indirectly helping to maintain dissolved oxygen in water. When the water is clear and transparent, the light transmittance in the water increases, promoting the photosynthesis of aquatic plants and algae, further increasing the amount of dissolved oxygen in the water, which is particularly important for aquatic animals in cultivation.

[0003] However, the existing sand filter often encounters the following problems in use: the traditional sand filter in the treatment of aquaculture water containing more organic matter and excrement, due to the fact that organic matter and fish excrement are both viscous substances, and impurities tend to deposit and accumulate on the top or local area of the sand filter, causing blockage, resulting in poor water flow and reduced filtration efficiency, making the equipment need frequent maintenance and cleaning, affecting the use efficiency. SUMMARY

[0004] The main purpose of the utility model is to provide a sand filter with a swing filter screen to effectively solve the problem of the existing traditional sand filter mentioned in the background art, which is prone to impurities depositing and accumulating on the top or local area of the sand filter, causing blockage, and the need for frequent maintenance and cleaning of the equipment.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is:

[0006] A sand filter with a swing filter screen, comprising:

[0007] A sand filter housing is erected on the ground;

[0008] A feed pipe is provided on the top of the sand filter housing;

[0009] A sand inlet is located on one side of the feed pipe;

[0010] A mounting bracket is provided on the top of the sand filter housing;

[0011] A driving housing is mounted on the top of the mounting frame;

[0012] A driving motor is arranged on the top of the driving housing;

[0013] A main gear is arranged on the output end of the driving motor;

[0014] A first connecting rod is movably connected to the wheel surface of the main gear;

[0015] A second connecting rod is movably connected to the other end of the first connecting rod;

[0016] A rotating shaft rod is arranged on the other end of the second connecting rod and extends into the sand filter housing;

[0017] A swing filter housing is connected to the bottom end of the rotating shaft rod;

[0018] An opening is arranged on one end of the swing filter housing.

[0019] Further comprising:

[0020] A water collector is arranged in the sand filter housing;

[0021] A water outlet pipe is arranged on the bottom end of the sand filter housing;

[0022] Sand is arranged on the water collector and the swing filter housing is arranged above the sand.

[0023] The main gear, the first connecting rod and the second connecting rod are arranged in the driving housing.

[0024] The connecting end of the first connecting rod and the main gear is the non-axle center of the main gear.

[0025] The swing filter housing is arranged in the sand filter housing.

[0026] The outer surface of the swing filter housing is provided with filter holes.

[0027] Compared with the prior art, the fan-shaped reciprocating swing of the swing filter housing can stir the water in the sand filter housing.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0034] In the description of the present application, it should be further explained that, unless otherwise explicitly specified and limited, the terms "set", "set", "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application should be understood according to the specific circumstances.

[0035] For example, Figs. 1-3As shown, a sand filter with a swing filter screen, comprising: a sand filter housing 1, a feed pipe 2, a sand inlet 3, a mounting frame 4, a drive housing 5, a drive motor 6, a main gear 7, a first connecting rod 8, a second connecting rod 9, a rotating shaft rod 10, a swing filter housing 11. The sand filter housing 1 is erected on the ground, the feed pipe 2 is arranged at the top of the sand filter housing 1, the position of the feed pipe 2 is designed to facilitate the natural flow of water into the sand filter to start the filtering process. The sand inlet 3 is located on one side of the feed pipe 2, which mainly functions to supplement the filter sand 15 for the sand filter when needed. The filter sand 15 is an important medium in the sand filter filtering process, and as the use time increases, the filter sand 15 may need to be replenished due to wear, blockage, etc. The presence of the sand inlet 3 makes it convenient to replenish the filter sand 15. The mounting frame 4 is arranged at the top of the sand filter housing 1, and the mounting frame 4 provides a stable mounting base for the drive housing 5. Ensure that the drive housing 5 remains in a fixed position during operation to avoid displacement due to motor operation, thereby ensuring the stability of the entire transmission system. The drive housing 5 is installed on the top of the mounting frame 4.

[0036] In this embodiment, the output end of the drive motor 6 is arranged through the top of the drive housing 5, the main gear 7 is installed on the output end of the drive motor 6, and the connecting end of the first connecting rod 8 with the main gear 7 is the non-axle center of the main gear 7. One end of the first connecting rod 8 is movably connected with the wheel surface of the main gear 7, and one end of the second connecting rod 9 is movably connected with the other end of the first connecting rod 8. Due to its own connection mode, one end is limited on the rotating shaft rod 10, and it is non-axle connected with the first connecting rod 8 and shorter in length than the first connecting rod 8, producing a limited angle swing or sector reciprocating motion. This form of motion can effectively transmit power to the rotating shaft rod 10 through the connection with the rotating shaft rod 10. The bottom end of the rotating shaft rod 10 is arranged through the other end of the second connecting rod 9, and the bottom end of the rotating shaft rod 10 extends into the sand filter housing 1, the swing filter housing 11 is connected with the bottom end of the rotating shaft rod 10, the swing filter housing 11 is located in the sand filter housing 1, and the outer surface of the swing filter housing 11 is provided with filter holes. An opening 12 is arranged at one end of the swing filter housing 11. The main gear 7, the first connecting rod 8 and the second connecting rod 9 are all located in the drive housing 5. On the one hand, these components are protected from the erosion of external dust, moisture and other impurities, prolonging their service life; on the other hand, it also prevents operators from accidentally contacting the running components, improving safety.

[0037] Preferably, the water collector 13 is laid in the sand filter housing 1, the water outlet pipe 14 is located at the bottom end of the sand filter housing 1, the filter sand 15 covers the water collector 13, and the swing filter housing 11 is located above the filter sand 15. Under the drive of the driving motor 6, the fan-shaped reciprocating swing is carried out, which stirs the water body in the sand filter housing 1, so that the water body has flowability. This helps to prevent the deposition of organic matter and fish excrement in the sand filter, avoids local blockage, and ensures the smooth progress of the entire sand filtering process. The opening 12 of the swing filter housing 11 is designed to scoop a part of the organic matter into the interior during the swing process, reducing the direct contact of the organic matter with the filter sand 15. In this way, the possibility of the filter sand 15 being blocked by the organic matter can be reduced, the service life of the filter sand 15 can be prolonged, and the frequency of replacing the filter sand 15 can be reduced.

[0038] It should be noted that the sand filter with a swing filter screen designed by the utility model uses the water flow introduced into the sand filter housing 1, and then the organic matter and fish excrement in the aquaculture pond are introduced, at which time the driving motor 6 is started, the output end of the driving motor 6 rotates to drive the main gear 7, the main gear 7 rotates to drive the first connecting rod 8 of the wheel surface, one end of the first connecting rod 8 is driven to continuously swing the other end of the second connecting rod 9, because the other end of the second connecting rod 9 is limited on the rotating shaft 10, and the motion is transmitted through the non-axle center connection of the first connecting rod 8 and the gear, and in addition, the second connecting rod 9 is shorter than the first connecting rod 8, so that the second connecting rod 9 cannot complete the complete circumferential motion, instead, this connection mode and motion transmission mechanism makes the second connecting rod 9 produce limited angle swing or fan-shaped reciprocating motion, the rotating shaft 10 is driven by the second connecting rod 9 to perform axial reciprocating rotation, the rotating shaft 10 rotates to drive the bottom swing filter housing 11 to perform fan-shaped reciprocating swing, the swing filter housing 11 in swing stirs the water body to make the water body have flowability, so that the organic matter and fish excrement cannot be deposited, and at the same time, the opening 12 of the swing filter housing 11 also scoops a part of the organic matter into the interior to reduce the contact of the organic matter with the filter sand 15.

[0039] Although the embodiments of the utility model have been shown and described, for those skilled in the art, it is understood that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
