Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to equipment for treating meat product wastewater. Background Technology

[0002] In traditional meat processing wastewater treatment equipment, the wastewater treatment process involves multiple stages, among which mixing and conveying are crucial. The main function of traditional mixing devices is to ensure that the wastewater and added chemical agents (such as disinfectant) are mixed evenly at specific stages of wastewater treatment, such as in the disinfection tank, to enhance the disinfection effect. In terms of conveying, wastewater is generally transferred from one treatment area to the next through ordinary pipeline pumps or gravity flow.

[0003] However, existing meat processing wastewater treatment equipment has drawbacks. On the one hand, the separate structural design makes the device complex and occupies a large space, which not only increases the difficulty of equipment installation and maintenance, but also increases the site usage cost for enterprises. On the other hand, since it involves multiple independent devices, the number of failure points increases, affecting the continuity and stability of enterprise production, and increasing equipment maintenance costs and time costs. Therefore, an integrated meat processing wastewater treatment device was designed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a wastewater treatment device for meat products.

[0005] The technical solution of this utility model is: a meat product wastewater treatment equipment, including a purification tank, partitions, a water pump, an integrated stirring-conveying device, a connecting platform, a filter rail, an inlet pipe, and an outlet pipe. The purification tank is equipped with two partitions, which divide the purification tank into three areas. A water pump is installed on the front of the purification tank, and two areas are interconnected through the water pump. An integrated stirring-conveying device is installed on one side of the purification tank, and a connecting platform is installed on the other side of the purification tank. A filter rail is installed on the connecting platform. An inlet pipe is installed in the area of ​​the purification tank near the filter rail. Three outlet pipes are installed at the bottom of each area.

[0006] As an improvement to the above scheme, the three areas, from right to left, are a sedimentation tank, an aeration tank, and a disinfection tank.

[0007] As an improvement to the above solution, the integrated mixing-conveying device includes a motor, a rotating shaft, a screw shaft, mixing blades, and a conveying frame. The motor is installed on one side of the disinfection tank of the purification box, and the rotating shaft is installed on the output shaft of the motor. The bottom of the disinfection tank is rotatably connected to the mixing blades. The rotating shaft and the mixing blades are driven by a reversing gear set. The other end of the rotating shaft is equipped with a conveying frame, which is located between the sedimentation tank and the aeration tank. The screw shaft is installed inside the conveying frame and is fixedly connected to the rotating shaft.

[0008] As an improvement to the above solution, it also includes an aeration pipe, which is installed on one side of the aeration tank of the purification box.

[0009] As an improvement to the above solution, it also includes a protective cover, a ventilation window, and a dosing hopper. The top of the purification box is equipped with a protective cover, a dosing hopper is installed near the disinfection pool on the protective cover, and a ventilation window is opened near the aeration pool on the protective cover.

[0010] As an improvement to the above solution, the filter rail and the connecting platform are connected by bolts.

[0011] This utility model has the following advantages:

[0012] 1. This utility model achieves both mixing and conveying functions simultaneously through a single motor drive system. This integrated design greatly simplifies the equipment structure, reduces the equipment's footprint, and lowers equipment procurement costs. The stability of equipment operation is significantly improved, the probability of failure is reduced, and it also facilitates later maintenance and upkeep.

[0013] 2. This utility model uses a bolted connection, making the installation and disassembly of the filter rail very convenient.

Detailed Implementation

[0019] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0020] Example: Meat processing wastewater treatment equipment, such as Figures 1-4 As shown, the system includes a purification tank 1, partitions 4, a water pump 5, an integrated stirring-conveying device, a connecting platform 12, a filter rail 13, an inlet pipe 14, and an outlet pipe 15. The purification tank 1 has two partitions 4 installed inside, which divide the purification tank 1 into three areas. The water pump 5 is installed on the front of the purification tank 1, and the two areas are interconnected through the water pump 5. The integrated stirring-conveying device is installed on one side of the purification tank 1, and the connecting platform 12 is installed on the other side of the purification tank 1. The filter rail 13 is installed on the connecting platform 12. The inlet pipe 14 is installed in the area of ​​the purification tank 1 near the filter rail 13. Three outlet pipes 15 are installed at the bottom of each area.

[0021] The three areas, from right to left, are a sedimentation tank, an aeration tank, and a disinfection tank. This layout makes the wastewater treatment process clear and logical, and the overall layout is compact and reasonable, which facilitates management and maintenance by operators and also helps to improve wastewater treatment efficiency.

[0022] A motor 6 is installed on one side of the disinfection tank of the purification box 1. A rotating shaft 7 is installed on the output shaft of the motor 6. An agitator 9 is rotatably connected to the bottom of the disinfection tank. The rotating shaft 7 and the agitator 9 are driven by a reversing gear set. A conveyor frame 10 is installed at the other end of the rotating shaft 7. The conveyor frame 10 is located between the sedimentation tank and the aeration tank. A spiral shaft 8 is installed inside the conveyor frame 10. The spiral shaft 8 is fixedly connected to the rotating shaft 7. This design realizes the two major functions of stirring and conveying through a motor drive system, which simplifies the equipment structure, reduces the equipment procurement cost, and improves the stability of equipment operation by reducing the connection links between multiple independent devices.

[0023] An aeration pipe 11 is installed on one side of the aeration tank of the purification box 1, which provides sufficient oxygen for the microorganisms in the aeration tank, meets the needs of the microorganisms for aerobic respiration, and thus significantly enhances the ability of microorganisms to oxidize and decompose organic matter in wastewater.

[0024] The top of the purification tank 1 is equipped with a protective cover 2. A dosing hopper 3 is installed on the protective cover 2 near the disinfection tank. A ventilation window 201 is opened on the protective cover 2 near the aeration tank. The protective cover 2 prevents debris from falling into the purification tank 1, avoiding interference with the normal operation of the wastewater treatment equipment. It also ensures the safety of operators to a certain extent, preventing accidents. The ventilation window 201, located near the aeration tank, facilitates the discharge of waste gas generated in the aeration tank.

[0025] The filter element 13 is connected to the connecting platform 12 by bolts. This bolted connection makes the installation and disassembly of the filter element 13 very convenient. During wastewater treatment, the filter element 13 needs to be cleaned or replaced regularly. The bolted connection allows operators to quickly remove the filter element from the connecting platform for cleaning and maintenance.

[0026] Meat processing wastewater first flows into filter 13 through inlet pipe 14. Filter 13 performs preliminary filtration, trapping larger particles such as debris. The pre-filtered wastewater then flows into a sedimentation tank. In the sedimentation tank, smaller particles not filtered out by filter 13 gradually settle to the bottom. After a period of settling, motor 6 is started. The output shaft of motor 6 drives shaft 7 to rotate, which in turn drives screw shaft 8 to rotate. The screw shaft 8 transports the wastewater from the sedimentation tank to the aeration tank. After a period of transport, motor 6 is stopped, and aeration pipe 11 in the aeration tank is opened. Aeration pipe 11 continuously supplies air into the tank, providing a suitable living environment for microorganisms and promoting the oxidation and decomposition of organic matter in the wastewater. After a period of oxidation and decomposition, water pump 5 is started to pump the oxidized wastewater from the aeration tank into the disinfection tank. After extraction, motor 6 is started again. The output shaft of motor 6 drives shaft 7 to rotate. Shaft 7, through a reversing gear set, drives the stirring blades 9 to rotate in the disinfection tank, ensuring thorough mixing of the wastewater and disinfectant solution, thus achieving disinfection. Simultaneously, shaft 7 drives screw shaft 8 to rotate, continuously transporting wastewater from the sedimentation tank to the aeration tank, replenishing the wastewater and maintaining the continuity of the treatment process. After disinfection, outlet pipe 15 is opened to discharge the treated wastewater from the disinfection tank. By repeating the above operation process, batch treatment of meat product wastewater is achieved, thereby achieving the goal of efficient treatment of meat product wastewater.
