Description

Technical Field

[0001] The utility model belongs to the technical field of sewage sludge pressure filtration, and particularly relates to a sewage sludge pressure filtration device for environmental protection engineering. Background Technique

[0002] In environmental protection engineering, the use of sewage sludge pressure filtration is mainly to reduce the volume of sludge, lighten the disposal burden, recycle resources and protect the environment. Sewage sludge pressure filtration is a process of separating solids and liquids from sewage sludge through mechanical pressure. This process is an important link in sewage treatment, which effectively reduces the volume of sludge and improves the treatment and disposal efficiency of sludge.

[0003] Existing sewage sludge pressure filtration equipment usually directly puts the sludge into the interior of the pressure filter. Due to the existence of a large number of lumps in the sludge, it is difficult to press out the internal moisture, resulting in a large amount of moisture still remaining in the sludge after pressure filtration. At the same time, when the sludge with larger lumps enters the interior of the pressure filter, it is easy to cause blockage. Therefore, we propose a sewage sludge pressure filtration device for environmental protection engineering. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sewage sludge pressure filtration device for environmental protection engineering. By setting a crushing component, specifically, the motor drives the rotating rod to rotate, then the rotating rod drives the connecting rod to rotate through the support rod, and the crushing blocks on the connecting rod break the lumped sludge into small pieces without breaking the sludge. After treating the lumped sludge, the sewage inside the sludge can be better discharged, and the occurrence of blockage is reduced, improving the pressure filtration effect, and solving the problem that existing sewage sludge pressure filtration equipment usually directly puts the sludge into the interior of the pressure filter. Due to the existence of a large number of lumps in the sludge, it is difficult to press out the internal moisture, resulting in a large amount of moisture still remaining in the sludge after pressure filtration.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a sewage sludge pressure filtration device for environmental protection engineering, including a pressure filtration box. A feeding funnel is fixedly connected to the top of the pressure filtration box. A motor is fixedly connected to the front of the pressure filtration box. A drain pipe is fixedly connected to the lower left side of the front of the pressure filtration box, and the drain pipe communicates with the pressure filtration box. A baffle is arranged on the right side of the pressure filtration box. A partition one is fixedly connected to the left inner wall of the pressure filtration box, and a partition two is fixedly connected to the right inner wall of the pressure filtration box. A blanking port is formed on the side where the partition one and the partition two correspond to each other;

[0007] A crushing component is arranged inside the blanking port. The crushing component includes a rotating rod. Three connecting rods are arranged on the outer side of the rotating rod. A plurality of crushing blocks are fixedly connected to the outer surfaces of the three connecting rods. Support rods are fixedly connected to the front and back of the three connecting rods. The side of the support rod close to the rotating rod is fixedly connected to the surface of the rotating rod. By arranging the crushing component, specifically, the motor drives the rotating rod to rotate, then the rotating rod drives the connecting rods to rotate through the support rods, and the crushing blocks on the connecting rods break the agglomerated sludge into small pieces without crushing the sludge. After treating the agglomerated sludge, the sewage inside the sludge can be better discharged, and the occurrence of blockage is reduced, improving the effect of pressure filtration.

[0008] Further, a filter plate is arranged below the partition plate one. The outer sides of the four sides of the filter plate are fixedly connected to the inner wall of the pressure filtration tank. The top of the filter plate is in contact with the extrusion plate one. A long plate is fixedly connected to the left side of the extrusion plate one. The left side of the long plate penetrates through the pressure filtration tank and extends to the outside. The long plate is slidably connected to the pressure filtration tank. An extrusion plate two is arranged on the right side of the extrusion plate one. The extrusion plate one presses and filters the sludge under the cooperation with the extrusion plate two, thereby separating the solid from the liquid.

[0009] Further, a turning frame is fixedly connected to the right side of the baffle. A fixed shaft is rotatably connected inside the turning frame.

A jack is arranged inside the fixed frame. A plug rod is inserted into the jack. A limiting ring is fixedly connected to the outer surface of the plug rod. By arranging the plug rod, specifically, pulling out the plug rod from the fixed frame and then pulling the baffle to the right side. When the baffle moves above the fixed frame, inserting the plug rod into the fixed frame, then the limiting ring plays a limiting role on the plug rod. At this time, releasing the baffle, the baffle contacts the plug rod, thereby supporting the baffle, facilitating the staff to clean the inside, and reducing the situation of excessive sludge residue inside the pressure filtration tank.

[0010] Further, the top of the extrusion plate two penetrates through the partition plate two and extends to the outside. The extrusion plate two is slidably connected to the partition plate two. A hydraulic cylinder one is arranged on the right side of the feeding funnel. The bottom of the hydraulic cylinder one is fixedly connected to the top of the pressure filtration tank. The bottom output end of the hydraulic cylinder one is fixedly connected to the top of the extrusion plate two. Starting the hydraulic cylinder one drives the extrusion plate two to move upward, so that the extrusion plate two moves onto the partition plate two, facilitating the extrusion plate one to discharge the pressure-filtered sludge.

[0011] Further, a hydraulic cylinder two is fixedly connected to the left side of the pressure filtration tank. The right output end of the hydraulic cylinder two is fixedly connected to the left side of the extrusion plate one. The top of the extrusion plate one is in contact with the bottom of the partition plate one. The front and back of the rotating rod are rotatably connected to the pressure filtration tank. The front of the rotating rod is fixedly connected to the back output end of the motor. The back of the plug rod is in contact with the front of the fixed frame.

[0012] The utility model has the following beneficial effects:

[0013] 1. By setting a crushing component, specifically, the motor drives the rotating rod to rotate, then the rotating rod drives the connecting rod to rotate through the support rod, and the crushing blocks on the connecting rod break the agglomerated sludge into small pieces without smashing the sludge.

[0014] 2. By setting a plug rod, specifically, pulling out the plug rod from the fixing frame and then pulling the baffle to the right. When the baffle moves above the fixing frame, insert the plug rod into the fixing frame, then the limiting ring plays a limiting role on the plug rod. At this time, release the baffle, and the baffle contacts the plug rod, thereby supporting the baffle, facilitating the staff to clean the inside and reducing the situation of excessive sludge residue inside the pressure filtration box.

[0031] A specific application of this embodiment is:

[0032] In use, the sewage sludge is put into the filter press box 1 through the feeding funnel 11. Subsequently, the motor 2 is started to drive the rotating rod 131 to rotate. Then, the rotating rod 131 drives the connecting rod 132 to rotate through the support rod 134. The crushing blocks 133 on the connecting rod 132 break the agglomerated sludge into small pieces without crushing the sludge. After treating the agglomerated sludge, the sewage inside the sludge can be better discharged, and the situation of blockage can be reduced, improving the filtering effect. Then, the crushed sludge falls on the filter plate 14, and the filter plate 14 filters out the sewage in the sludge. The sewage is discharged to the bottom of the filter press box 1 and then discharged through the drain pipe 3. Subsequently, the motor 2 stops and the rotating rod 131 stops rotating. The hydraulic cylinder II 5 is started to drive the pressing plate I 141 to move to the right. The long plate 142 moves together. The long plate 142 is used to seal the feeding port positions corresponding to the partition plate I 15 and the partition plate II 16 to prevent the sewage sludge from falling. Then, the pressing plate I 141 presses and filters the sludge under the cooperation with the pressing plate II 143, thereby separating the solid from the liquid. After the pressing and filtering is completed, the hydraulic cylinder I 4 is started to drive the pressing plate II 143 to move upward, so that the pressing plate II 143 moves onto the partition plate II 16. Subsequently, the inserting rod 125 is pulled out of the fixing frame 124, and then the baffle 12 is pulled to the right. The flipping frame 121 rotates on the fixed shaft 122. When the baffle 12 moves above the fixing frame 124, the inserting rod 125 is inserted into the fixing frame 124. The limiting ring 126 plays a limiting role on the inserting rod 125. At this time, the baffle 12 is released, and the baffle 12 contacts the inserting rod 125, thereby supporting the baffle 12. Then, the right side of the filter press box 1 is opened. Through the continuous pushing of the pressing plate I 141, the pressed sludge is discharged from the right side of the filter press box 1. At the same time, after the baffle 12 is opened, it is more convenient for the staff to clean the inside, reducing the situation of excessive sludge residue inside the filter press box 1. Finally, the hydraulic cylinder II 5 drives the pressing plate I 141 to reset to the left, and the hydraulic cylinder I 4 drives the pressing plate II 143 to reset downward, so that the bottom of the pressing plate II 143 contacts the top of the filter plate 14, and the sewage sludge can be added again for the pressing and filtering work.
