Description

Technical Field

[0001] The invention relates to the technical field of filtration, in particular to a filter device for removing suspended solids in a fish pond. Background Art

[0002] In the process of raising fish in fish ponds, the fish excrement or fish food residues will remain in the fish pond. If they are not handled regularly, a large amount of suspended matter will exist in the fish pond. If the suspended matter is not handled regularly, it will pollute the water quality in the fish pond and deteriorate the living environment of the fish.

[0003] The patent with patent announcement number CN216062351U discloses a filter device for removing suspended solids in a fish pond, which saves costs, improves filtering effect, and improves practicality. The patent includes a filter tank and a first filter plate. A chamber is opened in the filter tank. The first filter plate is obliquely installed in the upper half of the chamber and divides the chamber into an upper chamber and a lower chamber. A first water pump is installed at the left end of the filter tank. The output end of the first water pump is connected to a water pumping pipe. A filter basket is installed at the end of the water pumping pipe. The output end of the water pump extends from the left end of the filter tank to the upper chamber. A sand filter device is horizontally installed in the lower half of the lower chamber. A second water pump is installed on the bottom wall of the lower chamber. A V-shaped water collecting cover is installed below the first filter plate. A downpipe is installed at the bottom end of the water collecting cover. The output end of the downpipe passes through the middle of the sand filter device and is connected to the input end of the second water pump.

[0004] However, the device still has some shortcomings: the device can filter the suspended solids in the fish pond, but when the filter component intercepts and filters the suspended solids and impurities in the sewage, the filter component is in a static state and only relies on the suction force of the water pump to drive the water flow to perform solid-liquid separation inside the filter component, which to a certain extent leads to limited effect of the filter component in intercepting suspended solids in the water flow. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a filter device for removing suspended solids from a fish pond, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions: a filter device for removing suspended solids in a fish pond, comprising a device body, a flat plate fixedly installed on the left side of the device body, a water pump arranged on the top of the flat plate, a spiral hose arranged at the bottom of the water pump, the outer wall of the spiral hose movably penetrates the inside of the flat plate, a water pipe is arranged on the right side of the water pump, the outer wall of the water pipe penetrates the inside of the device body, a sediment component is arranged inside the device body, and the sediment component is located below the water pipe, a filter component is fixedly installed at the bottom of the spiral hose, the filter component is connected to the spiral hose, a vertical plate is fixedly installed inside the filter component, and a double-axis motor is arranged on the right side of the vertical plate, A spiral blade is fixedly installed at the right output end of the dual-axis motor, a sealing ring is fixedly installed on the right side of the vertical plate, and the spiral blade is located inside the sealing ring. A plurality of filter plates are slidably installed on the inner wall of the filter assembly, and the plurality of filter plates are fixedly connected by connecting rods. A circular hole is opened at the center of the filter plate, and the filter plate is located on the left side of the vertical plate. A hollow box is fixedly installed at the bottom of the filter assembly, and two sliding plates are slidably installed inside the hollow box. A spring is fixedly installed at the bottom of the sliding plate, and a moving assembly is fixedly installed at the bottom edge of the sliding plate. The filter assembly is placed in a fish tank, and the buoyancy of the water causes the filter assembly to float in the water. The water pump is started, and the water pump is limited and stabilized by the flat plate. The spiral hose is used to cause the filter component to generate suction to transport the water through the spiral hose, and then the water pump discharges the water into the main body of the device through the water pipe, and the filter component intercepts the solid suspended matter in the water, and the water entering with sediment is filtered and intercepted by the sediment component, and then the water is discharged through the bottom of the main body of the device; when the filter component is in the fish tank, the dual-axis motor is started, and the output end of the dual-axis motor drives the spiral blades to rotate and generate thrust to push the filter component to move in the fish tank. At the same time, the vertical plate and the sealing ring seal and isolate the spiral blade part. At this time, the water flow disturbed by the spiral blade will not interfere with the filter plate, so that the solid suspended matter entering the filter component can be It is intercepted by multiple filter plates; when the water source in the fish tank becomes less and less, the filter component gradually sinks to the bottom of the fish tank under the action of its own gravity, and the filter component drives the hollow box to move synchronously, and the hollow box drives the sliding plate to move synchronously. When the sliding plate drives the spring piece to move downward, the arc surface at the bottom of the spring piece will first contact the bottom of the fish tank. At this time, the spring piece will slowly deform under the pressure of the gravity of the filter component. When the spring piece is deformed, it pushes the sliding plate to move away from the center of the hollow box. The sliding plate drives the moving component to move synchronously. After the spring piece is deformed, the moving component contacts the bottom of the fish tank, and when the filter component is displaced, the moving component contacts the bottom of the fish tank to generate friction and starts to rotate, thereby converting the sliding friction between the filter component and the fish tank into rolling friction.

[0007] According to the above technical solution, the two sliding plates are symmetrically distributed around the axis of the hollow box, and the outer walls of the sliding plates are movable through the interior of the hollow box. The movable component is positioned higher than the spring sheet, and an anti-centering device is provided on the left side of the filter component for diverting the water flow entering the filter component and carrying suspended solids up and down.

[0008] According to the above technical scheme, the anti-centering device includes a transmission rod, a collar, an L-shaped plate and a plurality of semicircular blocks. The right side of the transmission rod movably passes through and is fixedly installed at the left output end of the dual-axis motor. The inner wall of the collar is sleeved and slidably installed on the outer wall of the reciprocating spiral groove of the transmission rod. The right side of the L-shaped plate is fixedly installed at the left edge of the collar. A plurality of semicircular blocks are equidistantly installed on the outer wall of the L-shaped plate near the outer wall of the transmission rod. The output end of the dual-axis motor drives the transmission rod to rotate. When the transmission rod rotates, the collar is restricted by the reciprocating spiral groove of its own outer wall, and the collar is equipped with a card block that contacts the inner wall of the reciprocating spiral groove. Therefore, when the transmission rod rotates, it can drive the collar to slide left and right along its own outer wall. The collar drives the filter plate to slide synchronously along the inner wall of the filter assembly. At the same time, the collar also drives the L-shaped plate to move synchronously. The L-shaped plate drives the semicircular block to move synchronously. The semicircular block uses its own arc surface to perform arc-shaped guidance on the water flow passing through it.

[0009] According to the above technical solution, a reciprocating spiral groove is opened on the right side of the outer wall of the transmission rod, and the transmission rod is located inside the filter plate, the outer wall of the ring is fixedly connected to the inner wall of the filter plate, and a scraping device for moving aquatic plants or small gravel for easy removal is provided on the left side of the outside of the filter assembly.

The ends of the plurality of convex ball rods close to the outer wall of the transmission rod are equidistant and fixedly mounted on the outer wall of the cross bar. The inclined surface of the activated carbon plate contacts the arc surface of the outer wall of the convex ball rod. The right side of the waterproof ultraviolet lamp is fixedly installed at the left end of the cross bar, and the L-shaped plate drives the cross bar to move left and right, and the cross bar drives the convex ball rod and the waterproof ultraviolet lamp to move synchronously. The cross bar resists the activated carbon plate to generate a resistance force and causes the hinge shaft of the activated carbon plate to rotate. The activated carbon plate swings to the left and automatically resets through the torsion spring, and it swings back and forth. The L-shaped plate moves to the left and contacts the swinging activated carbon plate, and the activated carbon plate hits the L-shaped plate to activate the active molecules. After that, the L-shaped plate resists the hinge shaft of the activated carbon plate and starts to rotate to add secondary swinging power to the activated carbon plate.

[0011] According to the above technical scheme, the pulling device includes a screw rod, a limit ring and several blades. The right end of the screw rod is rotatably installed on the left side of the outer wall of the filter assembly. The outer wall of the screw rod movably penetrates the inside of the waterproof ultraviolet lamp. The right side of the limit ring is fixedly installed at the left corner of the waterproof ultraviolet lamp, and the inner wall of the limit ring is in contact with the outer wall of the screw rod. Several blades are fixed and equidistantly installed on the outer wall of the screw rod, and the blades are located between the right side of the waterproof ultraviolet lamp and the left side of the filter assembly. When the waterproof ultraviolet lamp moves to the left and resets, it drives the limit ring to slide synchronously along the outer wall of the screw rod. The built-in block of the limit ring is restricted by the non-self-locking spiral groove on the outer wall of the screw rod, so that when the limit ring slides, the screw rod generates a rotational force and starts to rotate, and the blade is driven to rotate when the screw rod rotates.

[0012] According to the above technical scheme, the pulling device also includes an arc-shaped plate and a circular plate. The arc-shaped plate is fixedly installed on the outer wall surface of the limiting ring near the center of the outer wall of the filter assembly. The right side of the circular plate is hinged to the left side of the filter assembly through a torsion spring. The inclined surface of the circular plate contacts the side of the arc-shaped plate away from the center of the outer wall of the filter assembly. The limiting ring drives the arc-shaped plate to move to the left and the top of the arc-shaped plate contacts the bottom inclined surface of the circular plate. At this time, the hinge axis of the circular plate starts to rotate along the outer wall of the filter assembly and the circular plate moves away from the outer wall of the screw rod. At this time, the circular plate pulls the aquatic plants or other debris in the direction to be irradiated by the waterproof ultraviolet lamp.

[0013] According to the above technical solution, the scraping device also includes a U-shaped frame and a trapezoidal shovel plate. The U-shaped frame is fixedly installed on the side of the curved plate close to the circular plate away from the center of the outer wall of the filter assembly. The trapezoidal shovel plate is hinged on the top of the U-shaped frame close to the circular plate, and the inclined surface of the trapezoidal shovel plate is in contact with the outer wall of the circular plate, and the curved plate drives the U-shaped frame to move synchronously, and the U-shaped frame drives the trapezoidal shovel plate to scrape synchronously along the outer wall of the circular plate.

An anti-centering device 4 is provided on the left side of the filter component 6 for diverting the water flow entering the filter component 6 and carrying suspended solids up and down.

[0022] When in use, the filter assembly 6 is placed in the fish tank, and the buoyancy of the water causes the filter assembly 6 to float in the water, and the water pump 3 is started. The water pump 3 is limited and stabilized by the flat plate 2, and the water pump 3 causes the filter assembly 6 to generate suction through the spiral hose 31 to transport the water flow through the spiral hose 31, and then the water pump 3 discharges the water flow into the device body 1 through the water pipe 32, and the filter assembly 6 intercepts the solid suspended matter in the water, and the water flow carrying the sediment is filtered and intercepted by the sediment assembly 33, and then the water flow is discharged through the bottom of the device body 1; when the filter assembly 6 When in the fish tank, start the dual-axis motor, the output end of the dual-axis motor drives the spiral blade 8 to rotate and generate thrust to push the filter assembly 6 to move in the fish tank, and at the same time, the vertical plate 7 and the sealing ring 9 seal and isolate the spiral blade 8.

A plurality of semicircular blocks 44 are equidistantly installed on the outer wall of the L-shaped plate 43 near the outer wall of the transmission rod 41. Through the above cooperation, the filter plate 10 can be moved back and forth to contact the water flow entering the filter assembly 6, shortening the contact time interval between the filter plate 10 and the solid suspended matter, reducing the solid suspended matter from overflowing the filter assembly 6 due to the untimely contact of the filter plate 10. At the same time, the semicircular blocks 44 cause the water flow to disperse and contact the filter plate 10 to achieve uniform interception of the solid suspended matter by the filter plate 10.

After that, the L-shaped plate 43 resists the hinge shaft of the activated carbon plate 45 and starts to rotate to add a second swinging power to the activated carbon plate 45. The above-mentioned reciprocating swing of the activated carbon plate 45 expands the contact range with the water flow, thereby purifying the harmful substances in the water to avoid polluting the external environment, and speeding up the water flow rate to achieve that the filter plate 10 can contact more water flow in the same time, thereby improving the removal quality of solid suspended matter in the water.

[0027] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes a prying device 5; The pulling device 5 includes a screw rod 51, a limiting ring 52 and a plurality of blades 53.

When the screw rod 51 rotates, it drives the blade 53 to rotate. Through the above cooperation, the waterproof ultraviolet lamp 48 is displaced to irradiate and kill bacteria inside the fish tank. The blade 53 prevents the waterproof ultraviolet lamp 48 from being entangled with water plants between the filter component 6, which causes the waterproof ultraviolet lamp 48 to be blocked in movement and damaged during the pulling process; the limit ring 52 drives the arc plate 54 to move to the left, and the top of the arc plate 54 hits the bottom inclined surface of the circular plate 55. At this time, the circular plate The hinge axis of plate 55 starts to rotate along the outer wall of filter assembly 6 and the circular plate 55 moves away from the outer wall of screw rod 51. At this time, the circular plate 55 scrapes the aquatic plants or other debris in the direction to be irradiated by waterproof ultraviolet lamp 48, and the arc plate 54 drives the U-shaped frame 56 to move synchronously, and the U-shaped frame 56 drives the trapezoidal shovel plate 57 to scrape synchronously along the outer wall of the circular plate 55. Through the above cooperation, the debris in the water is prevented from blocking the ultraviolet light, resulting in reduced sterilization effect in a partial range, and increased possibility of bacterial reproduction, and the cleanliness of the circular plate 55 is guaranteed to a certain extent to prevent the circular plate 55 from being attached and eroded by bacteria, and to prevent the circular plate 55 from carrying a pungent smell due to bacterial attachment and leaving the fish tank to affect the working environment.
