Description

Technical Field

[0001] The present application relates to the technical field of sludge treatment devices, and in particular to a sludge deep dehydration device. Background Art

[0002] Nowadays, most cities in my country have built centralized urban domestic sewage treatment plants. However, sewage treatment technology transfers a large amount of pollutants in sewage to residual sludge. The sludge output of sewage treatment plants has increased sharply, and a large amount of sludge cannot be disposed of. The sludge contains a large amount of water, so it is generally necessary to dehydrate the sludge to reduce the volume of the sludge before treating it.

[0003] Most of the existing sludge dewatering equipment uses centrifuges or filter presses for dewatering. Although these equipment can achieve sludge dewatering to a certain extent, the dewatering effect is not ideal, and there are problems such as high energy consumption and difficult equipment maintenance during the treatment process. Especially for sludge containing a large amount of capillary water and interstitial water, the existing dewatering equipment is often unable to completely remove the moisture therein, resulting in a high moisture content of the dehydrated sludge, and the filter cloth is difficult to replace, which affects the subsequent dewatering effect. Therefore, there is a large room for improvement;

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application discloses a sludge deep dehydration device, referring to Figure 1-Figure 3 , including a box body 1 and a mud storage frame 8, vacuum pumps 3 are arranged on both sides of the box body 1, and the input ends of the two vacuum pumps 3 are connected to the two sides of the box body 1 through two vacuum tubes 4 respectively. The two vacuum pumps 3 are manually started, and the inside of the box body 1 can be vacuumed through the two vacuum tubes 4. Both ends of the top of the box body 1 are fixedly connected with cover plates 6, and the two cover plates 6 block the two sides of the top of the box body 1. The middle part of the top of the box body 1 is fixedly connected to the bottom of the mud storage frame 8. A filter cloth 10 is arranged inside the mud storage frame 8. The filter cloth 10 is usually made of fiber materials. These fiber materials have good air permeability and filtering performance. The structure of the filter cloth 10 usually includes a surface layer, a filter layer and a support layer. The surface layer is responsible for direct contact with the sludge. Its material is required to be wear-resistant and corrosion-resistant to ensure that a good filtering effect is maintained during long-term use. The filter layer plays a major filtering role. It can effectively intercept large particles in the sludge while allowing water to pass through. The supporting layer enhances the overall strength of the filter cloth 10, so that it can withstand the mechanical pressure and tensile force during the dehydration process. Silt is poured on the top of the filter cloth 10. Under the vacuum action in the box 1, the pressure difference is formed, which quickly separates the water in the sludge, and the water in the sludge continuously drips down to the inside of the box 1, thereby deeply dehydrating the sludge. A stirring component is provided inside the sludge storage frame 8, which can stir the poured sludge to make it flat. Winding components are provided on both sides of the top of the sludge storage frame 8, and the winding component can drive the stirring component to move back and forth, thereby stirring and leveling the sludge. Two drainage pipes 2 with manual valves are connected to the bottom of one side of the box 1. When the sludge starts to be dehydrated, the two manual valves are manually opened to quickly discharge the water into the sewer through the two drainage pipes 2.

[0021] Reference Figure 1-Figure 3 A fixing frame 9 is inserted into one side of the mud storage frame 8, and the fixing frame 9 is fixedly connected to the filter cloth 10. Both ends of the fixing frame 9 are fixedly connected with fixing plates 11. The two fixing plates 11 are fixedly connected to the mud storage frame 8 by two bolts 12. A handle 13 is fixedly connected to one side of the fixing frame 9. If the filter cloth 10 needs to be replaced, the four bolts 12 can be rotated and unscrewed, and the fixing frame 9 and the filter cloth 10 are manually held by hand to pull out the handle 13, and then the new fixing frame 9 and the filter cloth 10 are inserted into one side of the mud storage frame 8 and fixed by bolts 12. A door is provided on one side of the box body 1. After the sludge dehydration is completed, the moisture inside the box body 1 is also completely discharged. When the fixing frame 9 and the filter cloth 10 are pulled out, the dehydrated sludge falls into the box body 1 under the blocking effect of the mud storage frame 8. The door is opened manually to take out the dried sludge.

[0022] Reference Figure 2 and Figure 3 The stirring assembly includes a sliding bar 14 and a stirring rod 15. The bottoms of both ends of the sliding bar 14 are respectively slidably connected to the two ends of the top of the mud storage frame 8, and the middle part of the bottom of the sliding bar 14 is fixedly connected to the stirring rod 15. The winding assembly includes a rotating shaft 16, a fixed block 17, two rotating discs 18 and two hemp ropes 19. The two fixed blocks 17 are both fixedly connected to the mud storage frame 8. One end of the rotating shaft 16 rotates through one of the fixed blocks 17 and is fixedly connected to the rotating disc 18. The other end of the rotating shaft 16 is rotatably connected to the other rotating disc 18. One end of the two hemp ropes 19 is respectively fixedly connected to the two sides of the sliding bar 14. The two hemp ropes 19 The other end is fixedly connected to two rotating disks 18 respectively. By rotating the rotating disk 18 of one winding assembly, the rotating shaft 16 of the winding assembly can be driven to rotate, and then the hemp rope 19 of the winding assembly is wound, thereby driving the sliding bar 14 and the stirring rod 15 to move toward the winding assembly, and the stirring assembly stirs the sludge. At the same time, the rotating shaft 16 of the other winding mechanism is driven to rotate by its own hemp rope 19, and the hemp rope 19 is unfolded. Rotating the rotating disk 18 of the other winding assembly can drive the stirring assembly to move toward the winding assembly, and then the sludge in the mud storage frame 8 is stirred back and forth, so that the poured sludge can be quickly leveled, which is convenient for rapid dehydration.

[0023] Reference Figure 3 Two partitions 5 are arranged inside the box body 1, and air holes 7 are opened on the top of the partitions 5. The partitions 5 can block dripping water to prevent the water from entering the vacuum pump 3 through the vacuum tube 4 and causing damage to the inside of the vacuum pump 3. The air holes 7 facilitate the flow of air in the box body 1 to be sucked by the vacuum pump 3, thereby vacuuming the box body 1.

[0024] The implementation principle of a sludge deep dehydration device in the embodiment of the present application is as follows: by setting a vacuum pump 3, a fixed frame 9, a filter cloth 10, a stirring assembly and a winding assembly, sludge is poured on the top of the filter cloth 10, and the rotating disk 18 of a winding assembly is rotated to drive the rotating shaft 16 of the winding assembly to rotate, and then the hemp rope 19 of the winding assembly is wound, thereby driving the sliding bar 14 and the stirring rod 15 to move toward the winding assembly, and the stirring assembly stirs the sludge. At the same time, the rotating shaft 16 of the other winding mechanism is driven to rotate by its own hemp rope 19, and the hemp rope 19 is unfolded. Rotating the rotating disk 18 of the other winding assembly can drive the stirring assembly to move toward the winding assembly, and then the sludge in the sludge storage frame 8 is stirred back and forth, so that the poured sludge is quickly leveled, and the two vacuum pumps 3 are manually started, and the inside of the box body 1 can be vacuumed through the two vacuum tubes 4. Under the vacuum effect in the box body 1, the moisture in the sludge continuously drips down to the inside of the box body 1, thereby quickly and deeply dehydrating the sludge. When the sludge begins to be dehydrated, the two manual valves are opened manually to quickly discharge the moisture to the sewer through the two drainage pipes 2. If the filter cloth 10 needs to be replaced, the four bolts 12 can be rotated and unscrewed, and the fixed frame 9 and the filter cloth 10 are manually pulled out by holding the handle 13, and then the new fixed frame 9 and the filter cloth 10 are inserted into one side of the mud storage frame 8 and fixed by bolts 12. A door is provided on one side of the box body 1. After the sludge is dehydrated, the moisture inside the box body 1 is also completely discharged. While the fixed frame 9 and the filter cloth 10 are pulled out, the dehydrated sludge falls into the box body 1 under the blocking effect of the mud storage frame 8. The door is opened manually to take out the dried sludge, which has the effects of convenient and rapid deep dehydration, easy replacement of the filter cloth 10 and easy removal of the dehydrated sludge.
