Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sludge reduction wastewater treatment device. Background Technology

[0002] Sludge reduction refers to reducing the sludge content in wastewater through various technologies and methods during the wastewater treatment process. Sludge reduction is of great significance for the stable operation of wastewater treatment plants and environmental protection. It can not only reduce the cost of sludge treatment and disposal, but also reduce the pollution of the environment and the land resources occupied by sludge.

[0003] Existing wastewater treatment equipment generally separates sludge through gravity sedimentation and then reduces the volume of the separated sludge. Natural sedimentation separation takes a relatively long time and generally cannot be combined with new wastewater, which affects the overall effect and results in low efficiency. Therefore, a sludge reduction wastewater treatment device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a sludge reduction wastewater treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sludge reduction wastewater treatment device includes a housing, a guide shell fixedly connected to the bottom end of the housing, a base plate fixedly connected to the bottom end of the guide shell, a first motor fixedly connected to the bottom end of the base plate, a first rotating shaft fixedly connected to the output end of the first motor penetrating the base plate, a stirring plate located inside the guide shell fixedly connected to the outer side of the first rotating shaft, a drain pipe located outside the first motor connected to the bottom end of the base plate, a stainless steel wedge mesh fixedly connected inside the drain pipe, a sludge discharge pipe connected to the side of the drain pipe away from the first motor, a fixing plate fixedly connected to the end of the sludge discharge pipe away from the first motor, a second motor fixedly connected to the side of the fixing plate away from the sludge discharge pipe, a second rotating shaft fixedly connected to the output end of the second motor penetrating the fixing plate, an auger fixedly connected to the outer side of the second rotating shaft, a nylon filter screen provided on the outer side of the sludge discharge pipe, a sewage pump connected to the bottom end of the drain pipe, and a sludge discharge port opened at the bottom end of the sludge discharge pipe.

[0007] Preferably, the lengths of the second rotating shaft and the auger are matched, and the lengths of the second rotating shaft and the auger are greater than the length of the sludge discharge pipe.

[0008] Preferably, the height of the stainless steel wedge mesh matches the height of the bottom end of the sludge discharge pipe, and the top end of the stainless steel wedge mesh fits into each other with the bottom end of the auger.

[0009] Preferably, the nylon filter screens are evenly arranged on the surface of the sludge discharge pipe with the center of the sludge discharge pipe as the center. Several nylon filter screens and one sludge discharge pipe are grouped together, and there are four groups in total, which are symmetrically arranged on both sides of the guide shell.

[0010] Preferably, the drain pipe, stainless steel wedge mesh, and sewage pump are arranged as a group, with a total of four groups. The drain pipe, stainless steel wedge mesh, and sewage pump are arranged symmetrically at the bottom end of the base plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the following components are provided: outer shell, guide shell, base plate, drain pipe, stainless steel wedge mesh, sludge discharge pipe, fixing plate, second motor, second rotating shaft, auger, nylon filter screen, sewage pump, and sludge discharge port. The sewage pump accelerates the entry of sewage and sludge into the drain pipe, the stainless steel wedge mesh achieves cement separation, the auger discharges the sludge, and the nylon filter screen removes excess water from the sludge. These components achieve a highly efficient sewage and sludge separation effect, more efficiently removing sludge from sewage. This solves the problem that existing sewage treatment equipment generally separates sludge through gravity sedimentation, then reduces the volume of the separated sludge. Natural sedimentation separation takes a relatively long time and generally cannot add new sewage midway, which affects the overall effect and results in low efficiency.

[0013] 2. In this utility model, the first motor, the first rotating shaft and the stirring plate can stir the sludge in the outer shell and the guide shell into the four drain pipes by rotating at low speed, which further improves the sludge reduction efficiency. The slope of the inner side of the guide shell can also effectively guide the direction of the sludge. Attached Figure Description

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A sludge reduction wastewater treatment device includes a housing 1, a guide shell 2 fixedly connected to the bottom end of the housing 1, a base plate 3 fixedly connected to the bottom end of the guide shell 2, a first motor 4 fixedly connected to the bottom end of the base plate 3, a first rotating shaft 5 penetrating the base plate 3 fixedly connected to the output end of the first motor 4, a stirring plate 6 located inside the guide shell 2 fixedly connected to the outside of the first rotating shaft 5, a drain pipe 7 located outside the first motor 4 connected to the bottom end of the base plate 3, and a stainless steel wedge mesh 8 fixedly connected inside the drain pipe 7. The side of pipe 7 away from the first motor 4 is connected to a sludge discharge pipe 9. The end of the sludge discharge pipe 9 away from the first motor 4 is fixedly connected to a fixing plate 10. The side of the fixing plate 10 away from the sludge discharge pipe 9 is fixedly connected to a second motor 11. The output end of the second motor 11 is fixedly connected to a second rotating shaft 12 that passes through the fixing plate 10. An auger 13 is fixedly connected to the outside of the second rotating shaft 12. A nylon filter screen 14 is provided on the outside of the sludge discharge pipe 9. The bottom end of the drain pipe 7 is connected to a sewage pump 15. A sludge discharge port 16 is opened at the bottom end of the sludge discharge pipe 9.

[0024] The second rotating shaft 12 and the auger 13 are of matching lengths. The length of the second rotating shaft 12 and the auger 13 is greater than the length of the sludge discharge pipe 9. The longer second rotating shaft 12 and the auger 13 allow them to enter the drain pipe 7, facilitating direct contact and cleaning of the sludge. The height of the stainless steel wedge mesh 8 matches the height of the bottom end of the sludge discharge pipe 9. The top end of the stainless steel wedge mesh 8 fits snugly against the bottom end of the auger 13, allowing the sludge to smoothly enter the sludge discharge pipe 9 through the auger 13. Nylon filter screens 14 are evenly spaced on the surface of the sludge discharge pipe 9, with the center of the pipe as the center. Several nylon filter screens 14 and a drain pipe 9 form a series of interconnected screens. The sludge pipes 9 form a group, with a total of four groups, and are symmetrically arranged on both sides of the guide shell 2. The multiple nylon filter screens 14 can better and more efficiently separate the sewage remaining in the sludge. The multiple sludge discharge pipes 9 further improve the separation efficiency of the sewage remaining in the sludge, making it easier to obtain sludge with lower water content and facilitating subsequent transportation. The drain pipes 7, stainless steel wedge mesh 8, and sewage pumps 15 form a group, with a total of four groups. The drain pipes 7, stainless steel wedge mesh 8, and sewage pumps 15 are symmetrically arranged on the left and right sides at the bottom end of the base plate 3. The multiple groups of drain pipes 7, stainless steel wedge mesh 8, and sewage pumps 15 effectively improve the separation efficiency of sewage and sludge.

[0025] Workflow: When a sludge reduction wastewater treatment device is needed, the entire unit is powered externally. Wastewater containing sludge is poured in from above the outer shell 1. A guide shell 2 is set up to initially guide the sludge in the wastewater. The output of the first motor 4 drives the first rotating shaft 5 to rotate, which in turn drives the stirring plate 6 to rotate. The stirring plate 6 moves the sludge in the guide shell 2. The sludge in the outer shell 1 and the guide shell 2 can be stirred into the four drain pipes 7 by low-speed rotation. The sludge reduction efficiency is further improved by the multiple drain pipes 7. At the same time, the sewage pump 15 draws out the sludge through the drain pipes 7. Wastewater and sludge are separated by a stainless steel wedge mesh 8. Wastewater passes smoothly through the stainless steel wedge mesh 8 and is discharged to a designated location by a sewage pump 15. The sludge on the stainless steel wedge mesh 8 is driven by the output end of the second motor 11 to rotate the second shaft 12. The second shaft 12 drives the auger 13 to rotate, which in turn carries the sludge on the stainless steel wedge mesh 8 into the sludge discharge pipe 9. The sludge moves within the sludge discharge pipe 9 as the auger 13 moves. Excess wastewater is discharged through a nylon filter 14 to the collection point below, while the sludge is discharged through the sludge discharge port 16 into a designated sludge collection device.
