Description

Technical Field

[0001] This utility model relates to the technical field of sludge water treatment equipment, specifically a multi-layer filtration sludge leachate water treatment equipment. Background Technology

[0002] Sludge is a solid sediment produced during water and wastewater treatment. It is mainly composed of organic matter, inorganic particles, microorganisms, and water. Due to its complex composition and the possibility of containing harmful substances, sludge treatment has become an important part of environmental protection and resource recovery. Sludge water treatment equipment plays a key role in this process, which mainly includes steps such as sludge thickening, dewatering, drying, and stabilization.

[0003] The prior art provides a sludge water treatment device (publication number CN218740648U), including a treatment box; the bottom of the treatment box is set as a conical bottom; a filter box is set inside the treatment box, and the bottom of the filter box is also set as a conical bottom; a precision filter screen is fixedly connected to the inner wall of the filter box, and a feed pipe is fixedly connected to the upper surface of the filter box. The upper end of the feed pipe penetrates through the upper side of the inner wall of the treatment box to its upper surface. A circular opening is opened at the center of the upper surface of the treatment box, and the inner wall of the circular opening is rotatably connected to the center of the feed pipe wall through a bearing; a support frame is fixedly connected to both the left and right sides of the upper surface of the treatment box, and the support frame is installed at the center of the upper surface of the treatment box. This utility model sets the filter box to be rotatable, so that the sludge water in the filter box is thrown out from the sludge under the high-speed rotation of the filter box, thereby quickly separating the sludge and water in the sludge water and increasing the speed of sludge treatment in the sludge water.

[0004] Based on the above patent search, the patents mentioned above only separate sludge from water in actual use, but lack the function of further filtering the separated water. Since the separated water may still contain harmful substances such as heavy metals and organic matter, the water that has not been further filtered may not meet the discharge standards. If it is discharged directly, it will not only cause secondary pollution to the environment, harm the ecosystem and human health, but also lead to environmental penalties or increased operating costs for enterprises. Therefore, we need to propose a multi-layer filtration sludge leachate water treatment device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution:

[0023] A multi-layer filtration sludge leachate water treatment device includes a base plate 1, a separation device 2 for separating sludge water from leachate installed on the top of the base plate 1, a sludge pipe 3 for facilitating sludge discharge connected to the bottom of the separation device 2, a first control valve 5 provided on the outside of the sludge pipe 3, a drain pipe 4 for facilitating sludge leachate discharge connected to the bottom of the separation device 2, and a second control valve 6 provided on the outside of the drain pipe 4.

[0024] The top of the base plate 1 is equipped with a filter assembly 7 for further filtration of sludge leachate, and the end of the drain pipe 4 away from the separation device 2 is equipped with a diversion assembly 8 for diverting and discharging sludge leachate.

[0025] The filter assembly 7 includes a filter box 71 fixedly installed on the top of the base plate 1. The filter box 71 is equipped with three sets of filter screens 72 for multi-stage filtration of sludge leachate. One side of the filter box 71 is connected to an outlet pipe 73. Through the arrangement of the filter assembly 7, the three sets of filter screens 72 facilitate multi-stage filtration of sludge leachate, which can remove suspended solids, particulate matter and harmful substances step by step, ensuring that the effluent quality meets the discharge standards. The outlet pipe 73 is used to discharge the filtered clean water, achieving efficient purification.

[0026] The diversion assembly 8 includes a connecting pipe 81 connected to the lower end of the drain pipe 4. The end of the connecting pipe 81 away from the drain pipe 4 is connected to a conveying pipe 82. The outer side of the conveying pipe 82 is connected to multiple diversion pipes 83. Multiple sets of liquid outlet holes 84 are opened on the outer side of the multiple diversion pipes 83 respectively. Through the arrangement of the diversion assembly 8, the diversion assembly 8 evenly distributes the leachate into the filter box 71 through the connecting pipe 81, the conveying pipe 82 and the multiple diversion pipes 83. The design of the liquid outlet holes 84 on the outer side of the diversion pipes 83 ensures that the leachate evenly covers the surface of the filter screen 72, avoids local overload or blockage, and improves filtration efficiency.

[0027] The ends of the multi-component diversion pipes 83 furthest from the delivery pipe 82 all penetrate the filter box 71 and are installed on one side inside the filter box 71. The multi-component diversion pipes 83 are all located on top of the multi-component filter screens 72. Through the setting of the diversion pipes 83, the other ends of the multi-component diversion pipes 83 are all installed on the inner wall of the filter box 71, ensuring that the diversion pipes 83 will not shift due to vibration or pressure changes during equipment operation, thus enhancing the stability of the diversion pipes 83 when discharging liquid. Moreover, the multi-component diversion pipes 83 are located on top of the filter screens 72, which can ensure that the exudate is evenly distributed. The even distribution of liquid reduces local wear and blockage of the filter screens 72 and extends the service life of the filter screens 72.

[0028] A support plate 9 is installed on one side of the filter box 71, and the delivery pipe 82 is installed on the top of the support plate 9. The support plate 9 ensures the stability and reliability of the diversion component 8, prevents the delivery pipe 82 from shifting due to vibration or pressure changes, and ensures uniform delivery of the exudate.

[0029] The filter box 71 is equipped with multiple sets of support frames 10. The bottom of multiple sets of filter screens 72 are respectively installed on the top of the multiple sets of support frames 10. The support frames 10 are set to ensure the stability of the filter screens 72, prevent the filter screens 72 from being deformed or damaged by water flow impact, and improve the reliability of equipment operation.

[0030] A flow guide seat 11 is installed at the bottom of the filter box 71. The flow guide seat 11 is set at an angle. By setting the flow guide seat 11, the angled design of the flow guide seat 11 can use gravity to accelerate the flow and discharge of filtered clean water, avoid the filtered liquid from stagnating at the bottom of the filter box 71, and improve the treatment efficiency.

[0031] Working Principle: In use, the separation device 2 initially separates the sludge from the leachate. By opening the first control valve 5, the sludge can be discharged through the sludge pipe 3. Then, the second control valve 6 is opened, allowing the sludge leachate to be discharged through the drain pipe 4. The leachate enters the diversion component 8 through the drain pipe 4 and is distributed to multiple diversion pipes 83 through the connecting pipe 81 and the conveying pipe 82. The diversion pipe 83 has multiple outlet holes 84 on its side wall, which makes the leachate evenly dispersed and flow into the filter box 71. This ensures that the leachate evenly covers the surface of multiple sets of filter screens 72 in the filter box 71, avoiding local overload or blockage. After the leachate falls from the multiple sets of outlet holes 84, it passes through three sets of filter screens 72 with different filtration precision in sequence, thereby removing suspended solids, particulate matter and dissolved harmful substances in stages, realizing multi-stage purification and filtration of sludge leachate, and ensuring that the effluent meets environmental discharge standards.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
