Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for processing pet dog and cat food. Background Technology

[0002] Pet food for dogs and cats refers to nutritionally balanced food formulated specifically for domestic dogs and cats, typically including various forms such as dry food, wet food, freeze-dried food, and functional supplements. With the rapid development of the pet economy, the pet food industry has become increasingly large-scale and industrialized. Its production process involves multiple stages, including raw material cleaning, cooking, seasoning, and cooling, all of which generate large amounts of processing wastewater containing high concentrations of organic matter. This wastewater is characterized by high suspended solids content, high oil content, good biodegradability but also a tendency to decompose and produce foul odors. If discharged directly without effective treatment, it will cause serious pollution to the surrounding water environment, affecting the ecological environment and residents' lives.

[0003] Taking a feed wastewater filtration device disclosed in utility model patent CN207769327U as an example, this device uses a mechanical filtration structure composed of a filter cartridge, filter bag, compression ring, and fixing ring to achieve preliminary interception and collection of recyclable solids in wastewater, thus improving the convenience of solid-liquid separation to a certain extent. However, the device lacks any flow guiding structure to direct the wastewater flow, resulting in the wastewater flowing freely and disorderly after entering the filter cartridge. Some of the water flows down the inner wall of the filter cartridge, making it easy for impurities to adhere to the side wall surface of the filter cartridge, forming an adhesive layer. This not only reduces the filtration efficiency but also significantly increases the workload and frequency of subsequent manual cleaning, affecting the continuous operation capability of the equipment.

[0004] Therefore, addressing the shortcomings of existing technologies, we urgently need a wastewater treatment device for processing pet dog and cat food. This device should, while retaining the original solid-liquid separation function, optimize the internal water flow path structure to improve the orderliness of wastewater flow and filtration efficiency, while reducing the adhesion rate of impurities on the inner wall of the filter cartridge. This would significantly improve the stability of equipment operation and ease of maintenance, better meeting the needs of modern pet food production enterprises for efficient, environmentally friendly, and intelligent wastewater treatment equipment, and providing strong support for the industry's green and sustainable development. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater treatment device for processing pet dog and cat food. It solves the problem in the prior art where no guiding structure is set inside to guide the flow of wastewater, resulting in the wastewater flowing freely in a disordered state after entering the filter cartridge, and some water flowing down along the inner wall of the filter cartridge, making it easy for impurities to adhere to the side wall surface of the filter cartridge.

[0006] To achieve the above objectives, this utility model provides a wastewater treatment device for processing pet dog and cat food, including a filter cartridge, an inlet pipe connected to the top of the filter cartridge, and a drain pipe connected to the bottom of the filter cartridge.

[0008] The filter cartridge has a filter inner cylinder connected to a mounting ring plate at its top and a filter bag connected to the mounting ring plate at its bottom. The bottoms of the filter inner cylinder and the filter bag are both located inside a guide cover. The bottom of the guide cover extends to the top of the filter bag, and the bottom end of the liquid inlet pipe extends to the top of the filter inner cylinder.

[0009] The outer ring of the supporting ring plate is fixedly connected to the inner wall of the filter cylinder, the inner filter cylinder is conical in shape, and several through grooves are opened on the outside of the inner filter cylinder.

[0010] The guide cover is conical in shape, and the diameter of the bottom end of the guide cover is smaller than the diameter of the top end.

[0011] The mounting ring plate has several positioning screws fixedly connected to its bottom, and the supporting ring plate has several positioning holes adapted to the positioning screws on its top. The bottom end of the positioning screw is threaded with a positioning nut.

[0012] The guide cover is fixedly connected to a connecting ring plate that is fixedly connected to the bottom bolt of the mounting ring plate at its top edge, and the filter inner cylinder is fixedly connected to a fixing ring plate that is fixedly connected to the top bolt of the mounting ring plate at its top edge.

[0013] The filter bag is fixedly connected to a connecting edge ring at its top edge. The top of the connecting edge ring has several round holes, and each round hole has a positioning hook inside. The bottom end of the positioning hook is fixedly connected to the top of the mounting ring plate.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example 1

[0024] Please see Figure 1-5 As shown, this embodiment of a wastewater treatment device for processing pet dog and cat food includes a filter cartridge 2, an inlet pipe 1 connected to the top of the filter cartridge 2, and a drain pipe 3 connected to the bottom of the filter cartridge 2. The filter cartridge 2 has two supporting ring plates 5 inside. The top of each of the two supporting ring plates 5 is detachably connected to an mounting ring plate 4, and the bottom of each of the two mounting ring plates 4 is detachably connected to a guide cover 6. The top of the filter cartridge 2 has a filter impurity inner cylinder 7 connected to the mounting ring plate 4, and the bottom of the filter cartridge 2 has a filter bag 8 connected to the mounting ring plate 4. The bottoms of both the filter impurity inner cylinder 7 and the filter bag 8 are located inside the guide cover 6. The bottom of the guide cover 6 extends to the top of the filter bag 8, and the bottom of the inlet pipe 1 extends to the top of the filter impurity inner cylinder 7.

[0025] The pet food processing wastewater to be treated is introduced through the inlet pipe 1. The wastewater first enters the filter inner cylinder 7, where large particles of impurities are initially filtered out. Then it flows into the guide cover 6 and, under the action of the guide cover 6, flows to the filter bag 8 below for further solid-liquid separation. Finally, it is discharged through the drain pipe 3. During this process, the guide cover 6 effectively avoids the phenomenon of wastewater directly impacting the inner wall of the filter cylinder 2 and flowing along the wall surface, reducing the adhesion of impurities on the inner wall of the filter cylinder 2. At the same time, the detachable connection between the components also facilitates regular cleaning and replacement of the filter media.

[0026] Example 2

[0027] Please see Figure 1-5 As shown in this embodiment, a wastewater treatment device for processing pet dog and cat food includes a supporting ring plate 5 whose outer ring is fixedly connected to the inner wall of a filter cartridge 2. The inner filter cartridge 7 is conical in shape and has several through-grooves on its exterior. Specifically, through the fixed connection of the supporting ring plate 5 to the inner wall of the filter cartridge 2, and the conical shape of the inner filter cartridge 7 with several through-grooves, when wastewater enters the inner filter cartridge 7, the conical design guides the water flow downwards, and it undergoes preliminary filtration through the through-grooves to remove large particulate impurities. This structure not only improves the solid-liquid separation efficiency but also prevents impurities from accumulating inside the filter cartridge 2, achieving optimized filtration and reduced clogging risk.

[0028] Several positioning screws 11 are fixedly connected to the bottom of the mounting ring plate 4, and several positioning holes adapted to the positioning screws 11 are opened on the top of the supporting ring plate 5. Positioning nuts are threaded to the bottom end of each positioning screw 11. Specifically, by using the positioning screws 11 fixedly connected to the bottom of the mounting ring plate 4 to mate with the positioning holes on the top of the supporting ring plate 5 and locking them with positioning nuts, a stable connection between the mounting ring plate 4 and the supporting ring plate 5 is achieved. This design facilitates quick assembly and disassembly, simplifies the maintenance process, and ensures a tight fit between the components, thereby enhancing the structural strength of the device and facilitating maintenance.

[0029] Example 3

[0030] Please see Figure 1-5 As shown in this embodiment, a wastewater treatment device for processing pet dog and cat food has a conical guide shroud 6. The diameter of the bottom end of the guide shroud 6 is smaller than the diameter of the top end. Specifically, by designing the guide shroud 6 as conical with a smaller bottom diameter than the top diameter, after the wastewater flows out of the filter inner cylinder 7, the guide shroud 6 can concentrate and smoothly guide the water flow to the filter bag 8 below, avoiding the problem of impurities adhering due to direct impact of the water flow on the inner wall of the filter cylinder 2. This design makes the water flow more orderly, enhances the filtration efficiency, reduces the maintenance frequency, and achieves the effects of improving equipment operating stability and reducing cleaning difficulty.

[0031] A connecting ring plate 10, which is fixedly connected to the bottom bolt of the mounting ring plate 4, is fixedly connected to the top edge of the guide cover 6. Similarly, a fixing ring plate 9, which is fixedly connected to the top bolt of the mounting ring plate 4, is fixedly connected to the top edge of the filter inner cylinder 7. Specifically, the design of the connecting ring plate 10 fixedly connected to the top bolt of the mounting ring plate 4 at the top edge of the guide cover 6, and the fixing ring plate 9 fixedly connected to the top bolt of the mounting ring plate 4 at the top edge of the filter inner cylinder 7, ensures the secure installation of the guide cover 6 and the filter inner cylinder 7. This multi-point fixing method increases the stability of the overall structure, prevents components from loosening or falling off, and achieves the effect of improving equipment operating safety and extending service life.

[0032] A connecting ring 12 is fixedly connected to the top edge of the filter bag 8. The top of the connecting ring 12 has several circular holes 14, and each circular hole 14 contains a positioning hook 13. The bottom end of the positioning hook 13 is fixedly connected to the top of the mounting ring plate 4. Specifically, this design, where the connecting ring 12 is fixedly connected to the top edge of the filter bag 8, has positioning hooks 13 inside the circular holes 14, and the bottom end of the positioning hooks 13 is fixedly connected to the top of the mounting ring plate 4, provides a convenient way to replace the filter bag 8. This design makes the filter bag 8 easy to disassemble and replace, reducing downtime, while ensuring sealing and preventing leakage, thus simplifying maintenance and ensuring filtration efficiency.

[0033] This solution includes the following workflow:

[0034] The overall structure includes a filter cartridge 2, with an inlet pipe 1 connected to the top and a drain pipe 3 connected to the bottom, for inputting wastewater and outputting treated liquid. Inside the filter cartridge 2 are two supporting ring plates 5, their outer rings fixedly connected to the inner wall of the filter cartridge 2 to support the upper components. Each of the two supporting ring plates 5 has a detachable mounting ring plate 4 at its top. The bottom of each mounting ring plate 4 is inserted into a positioning hole on the supporting ring plate 5 via a positioning screw 11, and locked in place with a positioning nut, thus achieving stable installation and convenient disassembly. The bottom of the mounting ring plate 4 is also fixedly connected to a guide cover 6 via a connecting ring plate 10. The guide cover 6 has a conical structure, with a bottom diameter smaller than the top diameter. The filter cylinder 2 has a conical inner cylinder 7, which is fixed to the top of the mounting ring plate 4 by a fixing ring plate 9 and a mounting ring plate 4. The inner cylinder 7 has several through grooves on the outside for preliminary filtration of large particles. The filter cylinder 2 has a filter bag 8 at the bottom, with a connecting ring 12 at its top edge. The connecting ring 12 has several round holes 14, and a positioning hook 13 is set in the round holes 14. The bottom end of the positioning hook 13 is fixedly connected to the top of the mounting ring plate 4, so as to stably suspend the filter bag 8 inside the filter cylinder 2. In the whole device, the bottom of the guide cover 6 extends to the top of the filter bag 8 to ensure that the water flows smoothly into the filter bag 8. During operation, the pet food processing wastewater to be treated enters the filter cartridge 2 through the inlet pipe 1, and extends from the bottom of the inlet pipe 1 to the top of the filter inner cylinder 7, allowing the wastewater to flow into the filter inner cylinder 7 first. At this stage, larger solid impurities are intercepted by the channel, completing the first stage of filtration. Subsequently, the wastewater that has undergone preliminary filtration enters the interior of the guide hood 6, and under the guidance of the conical structure of the guide hood 6, it flows to the filter bag 8 below for secondary fine filtration, removing smaller particles and suspended solids. Finally, the filtered clean water is discharged from the drain pipe 3, while the trapped impurities remain in the filter inner cylinder 7 and the filter bag 8, facilitating regular cleaning and replacement.

[0035] Through the aforementioned structural design, this device effectively solves the problems of disordered wastewater flow inside the filter cartridge, easy adhesion of impurities to the inner wall, and difficult cleaning in existing technologies. Specifically, the design of the guide cover 6 avoids direct impact of wastewater on the inner wall of the filter cartridge 2, reduces the deposition of impurities on the inner wall, improves the stability of equipment operation, and reduces the cleaning frequency; the filter inner cylinder 7 adopts a conical structure and is equipped with a through groove, which not only improves the solid-liquid separation efficiency but also prevents clogging; the detachable mounting ring plate 4, connecting ring plate 10, fixing ring plate 9, and filter bag 8 connection method make each component easy to replace and maintain, greatly simplifying the operation process and shortening downtime; at the same time, the matching structure of the positioning screw 11 with the positioning hole and positioning nut enhances the connection strength between each layer of components, prevents loosening or falling off, and ensures the safety of equipment operation; in addition, the filter bag 8 achieves quick installation and replacement through the combination of the connecting side ring 12 and the positioning hook 13, further improving the convenience of operation and sealing, and preventing liquid leakage.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
