Description

Technical Field

[0001] This application relates to the field of pig slaughterhouse technology, and in particular to a wastewater treatment device for pig slaughterhouses. Background Technology

[0002] As a facility for processing live pigs, the efficiency and quality of wastewater treatment in a pig slaughterhouse are crucial to its normal production and operation. Pig carcass slaughter is a complex process that generates a large amount of wastewater, hair, meat scraps, and other impurities. These impurities flow into the sewage pipes along with the wastewater. Because hair and meat scraps are sticky and difficult to decompose, they easily entangle and accumulate within the pipes, adhering to the inner walls. Over time, these impurities accumulate, gradually forming a thick layer of blockage.

[0003] However, existing sewage pipes usually lack effective impurity separation and transportation mechanisms, which makes it difficult to clean up the accumulated impurities inside the pipes. Cleaning these blocked pipes requires a lot of manpower and time, and the cleaning effect is often unsatisfactory.

[0004] Furthermore, the accumulation of impurities in the sewage pipes will reduce the effective flow area of ​​the pipes, increase the flow resistance of sewage in the pipes, slow down the flow velocity, and reduce the sewage discharge efficiency.

[0005] To address the aforementioned problems, a wastewater treatment device for pig slaughterhouses is now designed. Utility Model Content

[0006] This application provides a wastewater treatment device for pig slaughterhouses to solve the problem that some sewage pipes in the related technology lack an effective impurity separation and transportation mechanism, making it inconvenient to clean up impurities after they accumulate in the pipes, and slowing down the flow rate and reducing sewage discharge efficiency.

[0007] Firstly, a wastewater treatment device for a pig slaughterhouse is provided, comprising: A slaughterhouse, which includes a processing room for slaughtering pigs, has two sewage pipes facing each other inside the processing room. Filter plates are installed on the sewage pipes. The sewage pipes are characterized by having a liquid collection pipe at the bottom and multiple drainage holes connected to the liquid collection pipe at the bottom. A conveying component is installed inside the sewage pipe, and a fixed sewage outlet is connected to the bottom of one end of the sewage pipe. The conveying component is used to push impurities inside the sewage pipe to the fixed sewage outlet. One end of the liquid collection pipe is connected to a drain pipe, which is used to discharge the sewage inside the liquid collection pipe.

[0008] In some embodiments, the slaughterhouse has two mounting slots facing each other, and the sewage pipes are respectively arranged in the corresponding mounting slots; The filter plate is snapped into the mounting groove, and the upper surface of the filter plate is level with the floor of the processing chamber.

[0009] In some embodiments, the sewage pipe is located in a semi-circular pipe with an open top, and the filter plate is arranged at the opening of the sewage pipe; Multiple drainage holes are equidistantly located at the bottom of the sewage pipe along the length of the processing chamber.

[0010] In some embodiments, the liquid collection pipe includes interconnected liquid pipes and a guide chamber, the guide chamber being located in a rectangular shell with openings at both its upper and lower ends, the upper opening of the guide chamber being connected to the bottom of the drain pipe, and a plurality of drain holes being located inside the guide chamber; An opening is provided above the liquid pipeline, located inside the guide chamber, through which wastewater flowing out of the drain hole enters the liquid pipeline.

[0011] In some embodiments, the drain pipe is located at one end of the liquid conduit, and the two are interconnected.

[0012] In some embodiments, the conveying component includes a spiral conveying rod rotatably disposed inside the sewage pipe, a drive motor and a reducer disposed at one end of the sewage pipe, wherein the output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the spiral conveying rod. The drive motor is used to drive the spiral conveyor to rotate, pushing the impurities in the sewage pipe to the fixed sewage outlet for discharge.

[0013] In some embodiments, the other end of the fixed sewage outlet is connected to an external fixed waste collection trough; The other end of the drain pipe is connected to an external sewage treatment tank.

[0014] In some embodiments, the sewage pipe is also equipped with multiple stabilizers; The stabilizing frame includes a fixing plate mounted on the sewage pipe, with a support ring at the bottom of the fixing plate. The spiral conveying rod rotatably engages with the support ring. The spiral conveying rod rotates within the support ring, improving the stability of its rotation.

[0015] This application provides a wastewater treatment device for a pig slaughterhouse. Through the cooperation of a sewage pipe, a liquid collection pipe, a drainage hole, and a conveying component, it can efficiently separate solid impurities and liquids in the wastewater, thereby improving the efficiency of wastewater treatment. At the same time, it can promptly discharge solid impurities from the sewage pipe, preventing impurities from accumulating in the pipe and causing blockages.

[0016] The conveyor system keeps the sewage pipes clear and also holds solid impurities discharged from the sewage outlet, such as hair and meat scraps, for easy recycling. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] This application provides a wastewater treatment device for pig slaughterhouses, which can solve the problems in some related technologies where sewage pipes lack an effective impurity separation and transportation mechanism, making it inconvenient to clean up impurities after they accumulate in the pipes, and slowing down the flow rate and reducing sewage discharge efficiency.

[0022] Please see Figures 1-3 A wastewater treatment device for a pig slaughterhouse includes: a slaughterhouse 1, which has a processing chamber 2 for slaughtering pigs, two sewage pipes 3 facing each other in the processing chamber 2, and filter plates 4 installed on the sewage pipes 3. The sewage pipes 3 are characterized in that a liquid collection pipe 5 is installed at the bottom of the sewage pipes 3, and multiple drainage holes 6 connected to the liquid collection pipe 5 are opened at the bottom of the sewage pipes 3. A conveying component 7 is installed inside the sewage pipes 3, and a fixed sewage outlet 31 is connected to the bottom of one end of the sewage pipes 3. The conveying component 7 is used to push impurities inside the sewage pipes 3 to the fixed sewage outlet 31. A drain pipe 8 is connected to one end of the liquid collection pipe 5, and the drain pipe 8 is used to discharge the wastewater inside the liquid collection pipe 5.

[0023] Wastewater first flows through filter plate 4 installed on sewage pipe 3. Filter plate 4 takes into account the needs of personnel passage and can prevent large pieces of meat or items from falling into sewage pipe 3. At the same time, filter plate 4 has a certain strength to facilitate the movement of staff in processing room 2.

[0024] After initial interception by filter plate 4, the sewage enters the sewage pipe 3. Under the action of gravity, the liquid sewage can flow into the liquid collection pipe 5 through the drain hole 6, while solid impurities such as hair and meat scraps remain in the sewage pipe 3.

[0025] As the conveyor 7 operates, solid impurities in the sewage pipe 3 are pushed to the fixed sewage outlet 31 and discharged through the fixed sewage outlet 31. The liquid flowing into the liquid collection pipe 5 will flow along the pipe and be discharged to the outside through the drain pipe 8 for further purification and treatment.

[0026] Through the cooperation of sewage pipe 3, liquid collection pipe 5, drainage hole 6 and conveying component 7, solid impurities and liquid in sewage can be separated efficiently, improving the efficiency of sewage treatment. At the same time, solid impurities in sewage pipe 3 can be discharged in time, avoiding the accumulation of impurities in the pipe and causing blockage.

[0027] The conveyor 7 can keep the sewage pipe 3 unobstructed, and at the same time fix the solid impurities discharged from the sewage outlet 31, such as hair and meat scraps, for easy recycling.

[0028] like Figure 1 and Figure 3As shown in the figure, the slaughterhouse 1 described in this embodiment has two mounting slots facing each other inside, and the sewage pipes 3 are respectively arranged in the corresponding mounting slots; The filter plate 4 is snapped into the mounting groove, and the upper surface of the filter plate 4 is level with the ground of the processing chamber 2.

[0029] Two installation slots are left on the floor of slaughterhouse 1 to provide installation locations for sewage pipe 3.

[0030] During equipment installation, workers can install the sewage pipe 3 and liquid collection pipe 5 in the installation slot according to its location.

[0031] The filter plate 4 is installed inside the mounting slot by a snap-fit ​​method, which makes the installation and removal of the filter plate 4 very convenient.

[0032] The surface of filter plate 4 is kept level with the floor of processing chamber 2, which facilitates the smooth flow of sewage to filter plate 4 and also makes it easier for staff to move around.

[0033] like Figure 3 and Figure 5 As shown, in one embodiment, the sewage pipe 3 is located in a semi-circular pipe with an open top, and the filter plate 4 is arranged at the opening of the sewage pipe 3; a plurality of drainage holes 6 are equally spaced along the length of the processing chamber 2 at the bottom of the sewage pipe 3.

[0034] The sewage pipe 3 is semi-circular with an opening at the top, which gives the pipe a large opening area on the floor of the slaughterhouse, allowing the sewage generated on the floor of the processing room 2 to flow quickly into the sewage pipe 3.

[0035] The filter plate 4 is arranged at the opening of the sewage pipe 3. When sewage flows into the sewage pipe 3, it first passes through the filter plate 4. The pores on the filter plate 4 can intercept larger impurities in the sewage and prevent tools from falling into the sewage pipe 3.

[0036] Multiple drain holes 6 are equidistantly opened at the bottom of the sewage pipe 3 along the length of the processing chamber 2. The liquid in the sewage will flow into the liquid collection pipe 5 below through these drain holes 6. The drain holes 6 can prevent solid impurities from passing through and only allow the liquid to flow out smoothly.

[0037] like Figure 2 , Figure 3 and Figure 6As shown, in one embodiment, the liquid collection pipe 5 includes a liquid pipe 51 and a guide chamber 52 connected to each other. The guide chamber 52 is located in a rectangular shell and has openings at both its upper and lower ends. The upper opening of the guide chamber 52 is connected to the bottom of the sewage pipe 3, and a plurality of drainage holes 6 are located inside the guide chamber 52. An opening 53 is provided above the liquid pipe 51 and located inside the guide chamber 52. The guide chamber 52 guides the sewage flowing out of the drainage holes 6 into the liquid pipe 51 through the opening 53.

[0038] Sewage will flow into the sewage pipe 3, and the liquid in the sewage will enter the guide chamber 52 through the drain hole 6. The guide chamber 52 serves to temporarily store and guide the flow of sewage.

[0039] The liquid will naturally flow downward in the guide chamber 52 due to gravity. At the same time, it is constrained by the side wall of the guide chamber 52 and can flow in an orderly manner to the opening 53, and then into the liquid pipe 51.

[0040] The liquid collection pipe 5 forms a continuous channel. Sewage enters the guide chamber 52 from the sewage pipe 3 through the drain hole 6, and then flows from the guide chamber 52 into the liquid pipe 51 through the opening 53, completing the collection and transportation process of sewage in the liquid collection pipe 5.

[0041] like Figure 2 and Figure 6 As shown, it can be understood that the drain pipe 8 described in this embodiment is located at one end of the liquid pipe 51, and the two are interconnected.

[0042] When the liquid flows in the liquid pipe 51, it will enter the drain pipe 8, and the drain pipe 8 will transport the sewage to the external sewage treatment system for unified treatment.

[0043] like Figure 3 and Figure 4 As shown, in one embodiment, the conveying component 7 includes a spiral conveying rod 71 rotatably disposed inside the sewage pipe 3, a drive motor 72 and a reducer 73 disposed at one end of the sewage pipe 3, the output shaft of the drive motor 72 being connected to the input shaft of the reducer 73, and the output shaft of the reducer 73 being connected to the spiral conveying rod 71; the drive motor 72 is used to drive the spiral conveying rod 71 to rotate, pushing impurities in the sewage pipe 3 to the fixed sewage outlet 31 for discharge.

[0044] After the drive motor 72 starts, its output shaft begins to rotate, and the rotational power is transmitted to the reducer 73. The reducer 73 reduces the speed and increases the torque of the input high-speed rotation, and transmits the processed power to the screw conveyor 71. The surface of the screw conveyor 71 has helical blades.

[0045] When the spiral conveyor 71 rotates under the drive of the drive motor 72 and the reducer 73, the spiral blades will generate an interaction force with the impurities in the sewage pipe 3. The rotation of the spiral blades will push the impurities forward step by step along the spiral direction, moving the impurities from one end of the sewage pipe 3 to the other end.

[0046] As the screw conveyor 71 continues to rotate, the pushed impurities will gradually reach the position of the fixed drain outlet 31 and eventually be discharged from the drain pipe 3 through the fixed drain outlet 31.

[0047] The spiral blades of the spiral conveyor rod 71 can be adjusted according to the characteristics of impurities in the sewage pipe 3 and the conveying requirements.

[0048] Specifically, for cases with more impurities and larger particle sizes, a screw conveyor 71 with a larger pitch and thicker blades can be used to improve conveying capacity and wear resistance; for cases with fewer impurities and requiring precise conveying, a screw conveyor 71 with a smaller pitch and thinner blades can be used.

[0049] The continuous rotation of the spiral conveyor 71 enables the continuous pushing of impurities in the sewage pipe 3. Compared with traditional manual cleaning or other intermittent cleaning methods, it improves the efficiency of impurity cleaning. During the continuous production process in the slaughterhouse, the conveyor 7 can discharge the generated impurities in real time, avoiding the accumulation of impurities in the sewage pipe 3, ensuring the smooth flow of the sewage pipe 3, and reducing production interruptions and equipment damage caused by pipe blockage.

[0050] Cleaning the sewage pipes 3 promptly can reduce odors and bacterial growth.

[0051] It should be noted that, in this embodiment, the other end of the fixed sewage outlet 31 is connected to an external fixed waste collection trough; and the other end of the drainage pipe 8 is connected to an external sewage treatment pool.

[0052] The fixed waste collection tank collects and temporarily stores the impurities discharged from the fixed sewage outlet 31, facilitating subsequent processing and transportation.

[0053] Drainage pipe 8 is connected to an external sewage treatment tank, and sewage will flow into the sewage treatment tank along drainage pipe 8.

[0054] Specifically, after entering the wastewater treatment pond, wastewater undergoes a series of treatment processes, typically including pretreatment, biological treatment, and advanced treatment. Wastewater treated in the treatment pond, if meeting national discharge standards, can be directly discharged into natural water bodies. If higher water quality requirements are needed, the treated wastewater can be further treated for reuse, such as for workshop washing or greening irrigation, achieving water resource recycling. This is existing technology and will not be elaborated upon here.

[0055] like Figure 4 and Figure 5 As shown, in one embodiment, the sewage pipe 3 is also provided with a plurality of stabilizers 9; the stabilizer 9 includes a fixing plate 91 provided on the sewage pipe 3, and a support ring 92 is provided at the bottom of the fixing plate 91, and the spiral conveying rod 71 is rotatably engaged with the support ring 92.

[0056] When the screw conveyor 71 rotates under the drive of the drive motor 72 and the reducer 73, due to its long length, the screw conveyor 71 is prone to bending, deformation and swaying under the influence of its own weight and the reaction force generated when conveying impurities, which affects its normal rotation and conveying efficiency. The fixing plate 91 fixes the support ring 92 to the sewage pipe 3, so that the rod of the screw conveyor 71 can rotate inside the support ring 92. The support ring 92 provides a stable support point for the screw conveyor 71, restricting the displacement of the screw conveyor 71 in the radial and axial directions, so that it can only make stable rotational movements within the support ring 92, thereby improving the rotational stability of the screw conveyor 71.
