Description

Technical Field

[0001] This utility model relates to the technical field of sewer fittings, specifically a double-layer filtered clean floor drain for poultry hatcheries. Background Technology

[0002] During routine floor cleaning at poultry hatcheries, chicken feathers, manure, and other debris can easily clog sedimentation wells or traditional floor drains, leading to problems such as frequent manual cleaning, poor drainage, odor spread, and deterioration of environmental sanitation.

[0003] Currently, the floor drains commonly used in hatcheries are mostly traditional single-layer grating or simple sedimentation well structures. The typical structure is usually a precast concrete or plastic floor drain well with a single-layer metal grating at the top and a drainage pipe at the bottom. It relies on gravity settling and grating interception to initially filter large particles of impurities. After the sewage passes through the grating, it enters the drainage system. Because there is only one layer of filtration, large particles of impurities can easily and quickly clog the grating. The cycle of manual cleaning must be relatively frequent. If necessary, the well cover must be opened to clean the silt in the sedimentation well to ensure the normal use of the floor drain. The cleaning work is frequent and the internal silt is difficult to clean.

[0004] Based on this, the present invention designs a double-layer filtered clean floor drain for poultry hatcheries to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a double-layer filtered clean floor drain for poultry hatcheries, in order to solve the problem mentioned in the background art that the manual periodic cleaning cycle must be relatively frequent, and when necessary, the well cover needs to be opened to clean the silt in the sedimentation well, which is difficult to clean.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a drain pipe and a primary partition cover plate, wherein the drain pipe is a three-section stepped pipe that tightens sequentially from top to bottom, wherein the drain pipe is provided with an upper basket and a lower basket at the steps, and a top edge is fixedly connected to the top of the drain pipe, wherein the top edge has a folded edge, and the primary partition cover plate is located on the top edge.

[0007] As a further embodiment of this utility model, each step of the drain pipe is connected by a funnel-shaped edging. The top of the upper and lower baskets are provided with fixed handles, and the top edges of the upper and lower baskets are fixedly connected with open edging, which is adapted to the funnel-shaped edging.

[0008] As a further embodiment of this utility model, the drainage hole diameter of the primary partition cover is 5mm; the upper basket is a perforated plate structure with drainage holes diameter of 2mm and spacing of 15mm; the lower basket is also a perforated plate structure with drainage holes diameter of 1mm and spacing of 10mm.

[0009] As a further embodiment of this utility model, the upper basket and the lower basket are fixedly connected by a connecting rod. Both the upper basket and the lower basket have a central through hole in the middle. A central cover plate is rotatably connected to the top of the central through hole of both the upper basket and the lower basket. A spiral rod passes through the middle of the central cover plate, and brush rods are symmetrically fixedly connected to both sides of the central cover plate.

[0010] As a further embodiment of this utility model, an adapter seat is fixedly connected to the top of the central through hole, and the central cover plate is sleeved on the adapter seat and rotates with it.

[0011] As a further embodiment of this utility model, an operating rod is fixedly connected to the top of the spiral rod, and pull plates are symmetrically fixedly connected to the outside of the operating rod. A top handle is fixedly connected to the top of the upper basket.

[0012] As a further embodiment of this utility model, a storage tube is fixedly connected to the middle of the top handle, the top of the operating rod is located inside the storage tube and the two are slidably engaged, and a retraction spring is installed between the operating rod and the storage tube.

[0013] As a further embodiment of this utility model, the top of the upper basket is provided with a pressure rod, the bottom of the pressure rod is provided with an elastic telescopic cylinder, and the top of the pressure rod is fixedly connected to the primary partition cover plate.

[0014] As a further embodiment of this utility model, pressure blocks are provided at the four corners of the primary partition cover, and the pressure blocks are detachably installed at the folded edge.

[0015] As a further embodiment of this utility model, a recessed groove is provided at the four corners of the folded edge, and the pressing block is installed in the recessed groove and the two are magnetically attracted to each other; the pressing block is a rubber block and can be inserted into the recessed groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are: The three-layer tiered filtration structure pre-isolates large-particle debris, such as whole feathers, protecting the basket and extending the cleaning cycle; it separately intercepts medium and small-particle feathers and fecal matter, significantly reducing the probability of clogging. The folded edges enhance the strength of the drain pipe top, improving its resistance to deformation and preventing collapse and deformation during repeated high-pressure flushing and foot traffic, providing good support for the initial filter cover.

[0017] By repeatedly lifting the pull plate upwards, the operating lever and the spiral rod move up and down, which in turn causes the central cover plate that cooperates with the spiral rod to rotate back and forth. This causes the brush rod to brush over the surface of the basket repeatedly, effectively and quickly cleaning the impurities on the basket. After repeatedly lifting and pulling a few times, a simple water rinse will make it as clean as new. Compared with traditional brush cleaning or high-pressure washing methods, this is faster and more thorough, and can also brush out the impurities clogging the holes. Attached Figure Description

[0021] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Please see Figure 1-7The technical solution provided by this utility model is as follows: it includes a drain pipe 1 and a primary partition cover plate 2. The drain pipe 1 is a three-section stepped pipe that tightens from top to bottom. The drain pipe 1 is provided with an upper basket 3 and a lower basket 4 at the steps. The top of the drain pipe 1 is fixedly connected to a top edge 5. The top edge 5 has a folded edge 6. The primary partition cover plate 2 is located on the top edge 5.

[0025] This device employs a three-layer tiered filtration structure consisting of a primary diaphragm cover 2, an upper basket 3, and a lower basket 4. It pre-isolates large-particle debris, such as whole feathers, protecting the baskets and extending the cleaning cycle. It separately intercepts medium- and small-particle feathers and fecal matter, significantly reducing the probability of clogging and greatly minimizing sediment buildup within the drain pipe 1. The folded edge 6 enhances the strength of the top of the drain pipe 1, improving its resistance to deformation and preventing collapse or deformation during repeated high-pressure washing and foot traffic, while also providing excellent support for the primary diaphragm cover 2.

[0026] Example 1 Among them, each step of the drain pipe 1 is connected by a funnel-shaped rim. The top of the upper basket 3 and the lower basket 4 are both equipped with fixed handles 7. The top edges of the upper basket 3 and the lower basket 4 are both fixedly connected with open rims 8, which are adapted to the funnel-shaped rims.

[0027] Each basket is equipped with a fixed handle 7, which allows the basket to be manually lifted directly for easy cleaning; the open rim 8 enhances the fit with the inner ring of the drain pipe 1 and also facilitates the installation of the basket in place.

[0028] The primary partition cover 2 has a drainage hole diameter of 5mm; the upper basket 3 is a perforated plate structure with drainage holes diameter of 2mm and a spacing of 15mm; the lower basket 4 is also a perforated plate structure with drainage holes diameter of 1mm and a spacing of 10mm.

[0029] The primary baffle 2 can intercept large feathers, plastics, etc.; the upper basket 3 can intercept medium-sized impurities such as chicken feathers and rice husks; and the lower basket 4 can intercept small fecal residue and down. Based on the capillary action inhibition mechanism: the liquid surface tension formula is F = γ·cosθ, where γ is the liquid tension and θ is the contact angle; a 5mm pore diameter > the critical capillary value; the critical pore diameter for water is approximately 2mm, thus disrupting capillary action; a 2.5mm plate thickness shortens the liquid-solid contact time, accelerating drainage. Fluid simulation data shows a drainage rate of 0.5L / s, a 67% increase compared to the traditional 0.3L / s of a grid. Anti-adhesion synergistic effect: rapid drainage avoids impurity retention, reducing the amount of residual debris on the initial diaphragm cover by 90%. This prevents water film formation and adhesion, while also providing hydrophobic properties for rapid drainage.

[0030] Example 2 The upper basket 3 and the lower basket 4 are fixedly connected by a connecting rod 9. Both the upper basket 3 and the lower basket 4 have a central through hole 10 in the middle. The top of the central through hole 10 of both the upper basket 3 and the lower basket 4 is rotatably connected to a central cover plate 11. A spiral rod 12 passes through the middle of the central cover plate 11. Brush rods 13 are symmetrically fixedly connected to both sides of the central cover plate 11.

[0031] The top of the central through hole 10 is fixedly connected to an adapter 14, and the central cover plate 11 is sleeved on the adapter 14 and rotates with it.

[0032] Among them, the top of the spiral rod 12 is fixedly connected to the operating rod 15, the outside of the operating rod 15 is symmetrically fixedly connected to the pull plate 16, and the top of the upper basket 3 is fixedly connected to the top handle 17.

[0033] The top handle 17 is fixedly connected to a storage tube 18 in the middle, and the top of the operating rod 15 is located inside the storage tube 18. The two slide together, and a retraction spring 19 is installed between the operating rod 15 and the storage tube 18.

[0034] The upper basket 3 and the lower basket 4 are fixedly connected by the connecting rod 9. When the upper basket 3 is lifted out, both baskets can be lifted out at the same time to avoid the lower basket 4 being too deep and difficult to remove. After lifting the upper basket 3 and the lower basket 4 through the top handle 17, repeatedly lifting the pull plate 16 upwards causes the operating rod 15 and the spiral rod 12 to move up and down, which in turn causes the central cover plate 11, which cooperates with the spiral rod 12, to rotate back and forth. This causes the brush rod 13 to brush back and forth across the surface of the basket, effectively cleaning the impurities on the basket deeply and quickly. After lifting and pulling several times, a simple water rinse is all it takes to make it as clean as new. Compared with traditional brush cleaning or high-pressure washing, this method is faster and more thorough, and can also brush out the impurities clogging the holes.

[0035] The upper basket 3 is equipped with a pressure rod 20 at the top, and an elastic telescopic cylinder 21 is provided at the bottom of the pressure rod 20. The top of the pressure rod 20 is fixedly connected to the primary partition cover plate 2.

[0036] After the initial cover plate 2 is installed, the elastic shrink tube 21 presses on the top handle 17, and the upper basket 3 and the lower basket 4 are pressed together into the drain pipe 1 by the pressure rod 20 to avoid floating during filtration. At the same time, it helps the upper basket 3 and the lower basket 4 to be installed in a horizontal state to avoid tilting.

[0037] Among them, the primary partition cover plate 2 is provided with pressure blocks 22 at the four corners, and the pressure blocks 22 are detachably installed at the folded edge 6.

[0038] Among them, the four corners of the folded edge 6 are provided with sinking grooves, and the pressure block 22 is installed in the sinking grooves and the two are magnetically attracted to each other; the pressure block 22 is a rubber block and can be inserted into the sinking groove.

[0039] The pressure block 22 can be used to fix the primary partition cover 2 on the top edge 5, while the elastic shrink cylinder 21 is in a contracted state. After removing the pressure block 22, the primary partition cover 2 can be lifted upward by the elastic shrink cylinder 21, which makes it easy to take out the primary partition cover 2 without repeated snapping or other tools.

[0040] When removing the pressure block 22, it is easier to push it towards the center of the drain pipe 1 than to remove it straight up and down.

[0041] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
