Description

Technical Field

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

[0002] Meat processing generates large amounts of wastewater containing high concentrations of suspended solids, grease, protein, blood, and meat scraps. This wastewater is characterized by high organic content, high levels of suspended solids, and high perishability. Direct discharge without effective treatment will severely pollute aquatic environments, impacting ecological balance and public health. Therefore, developing efficient and practical wastewater treatment equipment tailored to the characteristics of meat processing wastewater is of paramount importance.

[0003] Traditional wastewater treatment methods typically employ gravity settling, bar screens, or simple filtration devices for pretreatment. However, due to their dispersed structures, low treatment efficiency, and limited automation, these methods often fail to meet increasingly stringent environmental emission standards. This is particularly true regarding issues such as filter media clogging, difficult cleaning, and complex operation and maintenance.

[0004] To address these issues, we provide a wastewater treatment system for meat processing. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The wastewater treatment tank includes a tank body, an overflow plate fixed to the bottom of the middle position of the tank body, a limiting frame fixed to the upper end of the overflow plate, a filter plate inserted into the limiting frame, a sedimentation chamber and a separation chamber separated inside the tank body by the filter plate, a backwashing assembly adapted to the separation chamber, a first discharge chamber connected to the bottom of the separation chamber, and a second discharge chamber connected to the bottom of the sedimentation chamber. The backwashing assembly includes a pump body fixed to the upper part of one end of the tank body, a water pipe connected to the output end of the pump body, and a flushing nozzle frame installed at the end of the water pipe.

[0025] Example

[0026] Please see Figure 1-5 This utility model relates to a wastewater treatment device for meat processing, comprising an integrated wastewater treatment tank 100. The wastewater treatment tank 100 includes a tank body 101, an overflow plate 113 fixed to the bottom of the middle position of the tank body 101, a limiting frame 114 fixed to the upper end of the overflow plate 113, a filter plate 115 inserted into the limiting frame 114, a sedimentation chamber 111 and a separation chamber 112 separated inside the tank body 101 by the filter plate 115, a backwashing assembly 105 adapted to the separation chamber 112, a first discharge chamber 107 connected to the bottom of the separation chamber 112, and a second discharge chamber 109 connected to the bottom of the sedimentation chamber 111. The backwashing assembly 105 includes a pump body 105a fixed to the upper part of one end of the tank body 101, a water pipe 105b connected to the output end of the pump body 105a, and a flushing nozzle frame 105c installed at the end of the water pipe 105b.

[0027] Specifically, the input end of the pump body 105a is connected to the interior of the separation chamber 112, the flushing nozzle frame 105c includes a plurality of inclined nozzles, the flushing direction of which is towards the filter plate 115, and the end of the flushing nozzle frame 105c is fixed to the inner wall of the separation chamber 112.

[0028] Furthermore, the side of the box body 101 is evenly distributed with reinforcing ribs 101a, the top of the box body 101 is fixed with an upper mounting frame 106, the upper mounting frame 106 is fixed with a box cover 103, the bottom of the box body 101 is fixed with a lower mounting frame 102, the lower mounting frame 102 is fixed with an external support structure by fasteners, and the upper end of the box cover 103 is sealed with an inspection window 103a, which is respectively located directly above the sedimentation chamber 111 and the separation chamber 112.

[0029] In addition, the sedimentation chamber 111 is equipped with a water inlet pipe 104, which passes through the side wall of the tank body 101 and is connected to the external sewage discharge end. The first discharge chamber 107 and the second discharge chamber 109 are both conical shell structures. The bottom port of the first discharge chamber 107 is equipped with a control valve 108, and the bottom port of the second discharge chamber 109 is equipped with a control valve 110.

[0030] The wastewater treatment equipment for meat processing provided in this embodiment aims to efficiently treat wastewater generated during meat processing. The integrated wastewater treatment tank 100 is internally divided into a sedimentation chamber 111 and a separation chamber 112 by an overflow plate 113 and a filter plate 115. These chambers are used for initial sedimentation of large particles and further filtration to separate fine suspended solids. Wastewater enters the sedimentation chamber 111 through the inlet pipe 104, where larger particles settle to the bottom under gravity and are subsequently discharged through the discharge chamber 109 and control valve 110. Wastewater enters the separation chamber 112 through the overflow plate 113 and passes through the filter plate 115. After fine filtration, solid-liquid separation is achieved. The filtered clean water can be discharged from the discharge chamber 107 and control valve 108 or enter the subsequent treatment stage. In order to ensure the permeability of the filter plate 115 and the long-term stable operation of the equipment, a backwashing assembly 105 is set up, including a pump body 105a, a water pipe 105b and a flushing nozzle frame 105c. The pump body 105a draws water from the separation chamber 112 and pressurizes it. Then, it uses multiple nozzles arranged at an angle to efficiently flush the filter plate 115, preventing clogging and improving filtration efficiency.

[0031] In addition, the entire box body 101 is equipped with reinforcing ribs 101a to enhance structural strength. The top is fixed with a box cover 103 with an inspection window 103a via an upper mounting frame 106, which facilitates observation and maintenance of the internal structure. The bottom is connected to the support structure via a lower mounting frame 102 to ensure the stability of the equipment. Its overall structure is compact and easy to operate, making it suitable for on-site use in meat processing enterprises. It has good application prospects and promotion value.

[0032] In use, the device is first fixed to the supporting structure via the lower mounting frame 102 to ensure overall stability. Then, wastewater generated during meat processing is introduced into the sedimentation chamber 111 through the inlet pipe 104. Under gravity, large particles such as meat scraps and grease residue settle to the bottom of the discharge chamber 109, and are periodically discharged by the control valve 110. After initial sedimentation, the wastewater enters the separation chamber 112 through the overflow plate 113 and undergoes fine filtration by the filter plate 115 inserted in the limiting frame 114 to further remove fine suspended solids, achieving solid-liquid separation. The treated clean water is discharged through the control valve 108 at the bottom of the discharge chamber 107 or enters the subsequent deep treatment process. To prevent the filter plates 115 from becoming clogged and affecting the treatment efficiency due to prolonged use, the equipment is equipped with a backwashing component 105. When cleaning is required, the pump body 105a is started to draw water from the separation chamber 112 and deliver it to the flushing nozzle frame 105c through the water pipe 105b. Multiple inclined nozzles perform high-pressure flushing of the filter plate 115 surface at multiple angles, causing the impurities attached to the filter plate 115 to be washed back to the bottom of the separation chamber 112, thereby restoring the permeability of the filter plate 115 and ensuring the continuous and stable operation of the equipment.
