[0033] like Figure 1-Figure 7As shown together, this embodiment provides a sludge dewatering device for water supply and drainage, which includes a table 1 and support bases 2 arranged at the four corners of the lower end of the table 1. A feed assembly 3 is provided at the upper end of the support base 2, and extrusion assemblies 4 are provided on both sides of the feed assembly 3. A dewatering assembly 5 is provided at the lower end of the feed assembly 3, and a dredging assembly 6 is provided on one side of the lower end of the table 1;

[0034] The dehydration component 5 includes an installation frame 51 arranged at the middle end of the table 1, and a filter plate 55 is inserted at the middle end of the inner wall of the installation frame 51. The filter plate 55 is evenly penetrated from top to bottom with several groups of filter holes 57. The dredging component 6 includes two groups of sliding sleeves 63 symmetrically mounted on the outer wall of the support seat 2. The end of the sliding sleeve 63 that is close to the end is provided with a connecting frame 61, and a dredging plate 62 is inserted at the middle end of the connecting frame 61. Several groups of dredging rods 65 are evenly provided on the upper end of the dredging plate 62.

[0035] The sliding sleeve 63 is movably mounted on the outer wall of the support seat 2, and sliders are provided at both ends of the dredging plate 62. Slide grooves that cooperate with the sliders are provided on both sides of the inner wall of the connecting frame 61. The length of the slide groove is smaller than the length of the connecting frame 61. A blocking rod 64 is fixedly provided at the lower end of the sliding sleeve 63 of the support seat 2. The diameter of the dredging rod 65 is slightly smaller than the diameter of the filter hole 57, and the dredging rod 65 and the filter hole 57 correspond one to one.

[0036] The feeding assembly 3 includes a dehydration box 31 fixedly arranged on the upper end of the table 1, and a discharge port 32 is opened through the middle part of the upper end of the dehydration box 31, and a sliding groove 33 is opened on the inner wall of the dehydration box 31 on one side of the discharge port 32, and a first cylinder 34 is fixedly provided on the dehydration box 31 on one side of the sliding groove 33, and a baffle 35 is connected to the output end of the first cylinder 34, and the baffle 35 can slide along the inner wall of the sliding groove 33, and a feed bin 36 is fixedly provided on the upper end of the dehydration box 31 at the upper end of the discharge port 32, and a downward-inclined feed port 37 is opened at the upper end of the feed bin 36, and a motor 38 is fixedly provided at the upper end of the feed bin 36, and a conveying auger 39 is connected to the output end of the motor 38, and the baffle 35 is located at the lower end of the feed bin 36, and the lower end of the feed bin 36 is in contact with the upper end of the baffle 35, and the lower end of the dehydration box 31 is in contact with the upper end of the filter plate 55.

[0037] The extrusion assembly 4 includes connecting plates 41 fixedly arranged on both sides of the upper end of the table 1. A second cylinder 42 is fixedly arranged on the adjacent end of the connecting plates 41. The output end of the second cylinder 42 is connected to the extrusion plate 43.

[0038] A sealing gasket 44 is provided on the outer wall of the extrusion plate 43 . The lower end of the sealing gasket 44 is in contact with the upper end surface of the table 1 , and the outer wall of the sealing gasket 44 is in contact with the inner wall of the dehydration box 31 .

[0039] When the sludge needs to be dehydrated, the motor 38 can be started to drive the conveying auger 39 to rotate, and then the sludge is put into the feed bin 36 through the feed port 37. Driven by the conveying auger 39, the sludge enters the dewatering box 31 through the discharge port 32, and then the first cylinder 34 is started to drive the baffle 35 to move along the sliding groove 33 to the upper end of the discharge port 32 to prevent the sludge from moving along the discharge port 32 to the feed bin 36 during the extrusion and dehydration process. Since the sludge is often sticky, the setting of the conveying auger 39 can prevent the sludge from being blocked in the feed bin 36 and making it impossible to discharge the material. After dredging, the dredging plate 62 can be retracted into the connecting frame 61, and then the sliding sleeve 63 is overlapped on the blocking rod 64 to prevent sewage from falling into the upper end of the dredging plate 62 during the sewage discharge process.

[0040] like Figure 1-Figure 3 As shown in common, a cavity is opened through the middle end of the table top 1, and the mounting frame 51 is inserted into the cavity.

The dehydration component 5 also includes two groups of fixed blocks 52 fixedly set on the upper end of the table top 1 and symmetrical to each other. Two groups of mounting blocks 53 are fixed on the upper end surface of the mounting frame 51 and symmetrical to each other. The middle ends of the fixing blocks 52 and the mounting blocks 53 on the same side are threadedly inserted with mounting rods 54, and one side of the front end of the mounting rod 54 passes through the fixing blocks 52 and the mounting blocks 53.

[0041] A filter plate 55 is movably inserted into the middle end of the mounting frame 51. The outer wall of the filter plate 55 fits in contact with the inner wall of the mounting frame 51. Four sets of symmetrical bolts 56 are threadedly inserted into the four corners of the outer wall of the mounting frame 51. The front ends of the bolts 56 movably penetrate the inner wall of the filter plate 55. The inner wall of the filter plate 55 is provided with insertion holes that cooperate with the bolts 56.

[0042] After the sludge dehydration is completed, the sludge entering the dehydration box 31 is squeezed into a sludge cake by the squeezing plate 43. Then the mounting rod 54 is rotated to remove the mounting rod 54 from the mounting block 53. Then the mounting frame 51 is pulled downward. The mounting frame 51 drives the filter plate 55 to rotate downward. The sludge squeezed into a cake falls to the ground through the cavity. The staff can quickly process the mud cake. Then, the bolts 56 are rotated outward to remove the four groups of bolts 56 from the upper end of the mounting frame 51 and remove the filter plate 55 from the mounting frame 51. Then the staff can rinse the filter plate 55, clean and maintain it, thereby facilitating subsequent dehydration.

[0043] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
