Description

Technical Field

[0028] Example 1

[0029] Reference Figures 1-2 A high-efficiency biochemical sludge dewatering device includes a bottom-mounted base, a dewatering collection mechanism, a blocking filtration mechanism, a conical spiral dewatering mechanism, and an anti-positioning mechanism.

[0030] The dewatering and collecting mechanism is fixed to the upper end of the bottom mounting base, which supports its placement. A blocking filter mechanism is sleeved inside the upper end of the dewatering and collecting mechanism, ensuring stable placement for biochemical sludge dewatering. A conical screw dewatering mechanism is fixed to the upper end of the dewatering and collecting mechanism, supporting its placement for dewatering. The biochemical sludge received by the conical screw dewatering mechanism is effectively dewatered by changing its radial displacement during axial transport. The water is dewatered by compression, and the water from the compression is filtered through a blocking and filtering mechanism and then transported to a dewatering collection mechanism for collection and discharge. The contact positioning mechanism is fixed to the left end of the conical screw dewatering mechanism. The contact positioning mechanism can make contact at the left end of the conical screw dewatering mechanism, thereby changing the size of the left end discharge area. The discharge gap is changed according to the same biochemical sludge dewatering material each time, thus making the biochemical sludge dewatering more efficient.

[0031] The bottom mounting base includes a four-hole mounting base plate 5, which can be installed in a designated position using screws. Symmetrically placed welded protrusions 61 are fixed to the four corners of the upper end of the four-hole mounting base plate 5, supporting the welded protrusions 61 during placement. A support column 6 is fixed to the upper end of each welded protrusion 61, providing support for the support column 6. A bottom protrusion 31 is fixed to the upper end of the support column 6, supporting the bottom protrusion 31. An outer ear plate 3 is fixed to the upper end of the bottom protrusion 31, supporting the outer ear plate 3. A dehydration collection mechanism is fixed to the inner end of the outer ear plate 3, supporting the dehydration collection mechanism for collection.

[0032] The dewatering and collection mechanism includes a hollow collection seat 32. The four corners of the hollow collection seat 32 are fixed to the outer ear plates 3. The hollow collection seat 32 can be supported and placed by the outer ear plates 3. A drainage pipe 33 is fixedly connected through the lowest point of the right end of the hollow collection seat 32. The water collected inside the hollow collection seat 32 can be discharged through the drainage pipe 33. The drainage pipe 33 is connected to the wastewater treatment equipment, so that the wastewater can be treated by the wastewater treatment equipment. A conical screw dewatering mechanism is fixedly connected to the upper end of the hollow collection seat 32. The water dewatered by the conical screw dewatering mechanism can be filtered and transported to the hollow collection seat 32. A blocking filter mechanism is sleeved on the inner side of the upper end of the hollow collection seat 32. The blocking filter mechanism can filter the water source of the biochemical sludge on the hollow collection seat 32.

[0033] The blocking and filtering mechanism includes a fixed end plate 4. A lifting handle 41 is fixedly connected to the middle of the outer end of the fixed end plate 4 for easy gripping and pulling open. A positioning screw 43 is installed on the inner side of the upper end of the fixed end plate 4. The fixed end plate 4 is fixed to the conical spiral rod dewatering mechanism by the positioning screw 43, so that the fixed end plate 4 can be placed stably. A positioning end plate 46 is symmetrically fixed to the inner end of the fixed end plate 4. When the fixed end plate 4 is pulled out, it can drive the positioning end plate 46 to be pulled out. A filter cloth connecting plate 42 is installed on the upper end of the positioning end plate 46. The positioning end plate 46 and the filter cloth connecting plate 42 are fixedly connected by assembly screws 44 and can be installed and fixed in place. A filter cloth body 45 is fixed between the two filter cloth connecting plates 42. The filter cloth body 45 can filter water sources and block sludge through fine mesh. The positioning end plate 46 is sleeved in the middle of the inner side of the hollow collection seat 32, so that it can be positioned and installed.

[0034] Working principle: The dewatering and collecting mechanism is supported by a base at the bottom. The blocking and filtering mechanism is fitted inside the upper end of the dewatering and collecting mechanism, allowing for stable placement and dewatering of biochemical sludge. The conical screw dewatering mechanism is supported at the upper end of the dewatering and collecting mechanism for dewatering. When the biochemical sludge received by the conical screw dewatering mechanism is conveyed radially, the radial displacement is changed, effectively squeezing and dewatering it. The squeezed water is filtered by the blocking and filtering mechanism and then transported to the dewatering and collecting mechanism for collection and discharge treatment. The contact positioning mechanism engages at the left end of the conical screw dewatering mechanism's discharge point, changing the size of the discharge area on the left side. By adjusting the discharge gap for each batch of the same biochemical sludge dewatering material, the dewatering efficiency of the biochemical sludge is improved.

[0035] Example 2

[0036] Reference Figure 1 , Figure 4 and Figure 5 A high-efficiency biochemical sludge dewatering device is described in this embodiment. Compared to Embodiment 1, the conical screw dewatering mechanism includes a biochemical sludge dewatering cylinder 1. A conical screw body 15 is rotatably mounted inside the biochemical sludge dewatering cylinder 1, allowing rotation within the cylinder. The conical screw body 15 can screw and extrude biochemical sludge. A contact positioning mechanism is sleeved on the left end of the conical screw body 15, allowing for adjustment of the contact. A discharge pipe 11 is fixedly connected to the lower left side of the biochemical sludge dewatering cylinder 1. The biochemical sludge dewatered inside the cylinder 1 is discharged through the discharge pipe 11. The right side of the biochemical sludge dewatering cylinder 1... A feed pipe 14 is fixedly connected to the upper side of the biochemical sludge, which can transport the received biochemical sludge to the biochemical sludge dewatering cylinder 1. A reducer 12 is installed on the right end of the conical screw rod body 15 on the biochemical sludge dewatering cylinder 1. When the output shaft of the reducer 12 rotates, it can drive the conical screw rod body 15 fixedly connected by the coupling to rotate. A geared motor 13 is fixedly connected to the right end of the reducer 12. When the output shaft of the geared motor 13 rotates, it can drive the output shaft inside the reducer 12 to rotate. A dewatering groove hole 16 is opened on the lower right side of the biochemical sludge dewatering cylinder 1. The water squeezed inside the biochemical sludge dewatering cylinder 1 can be discharged through the dewatering groove hole 16.

[0037] The filter cloth body 45 is attached to the dewatering groove hole 16 at the lower end of the biochemical sludge dewatering cylinder 1, so that it can be installed and placed accordingly for dewatering and filtration.

[0038] The positioning mechanism includes a mounting disc 21, which is screwed onto the left end of the biochemical sludge dewatering cylinder 1, allowing for stable installation. A first electric telescopic cylinder 2 is mounted on the upper and lower inner sides of the mounting disc 21, enabling it to extend and retract on the disc. A compression blocking ring 22, fitted onto the left end of the conical spiral rod body 15, is fixed to the telescopic rod end of the first electric telescopic cylinder 2. When the first electric telescopic cylinder 2 extends, it changes the position of the compression blocking ring 22 within the conical spiral rod body 15. The compression blocking ring 22 fits inside the biochemical sludge dewatering cylinder 1, acting like a syringe piston, allowing for positioning and movement. When moving, the compression blocking ring 22 changes the size of the slot at the upper end of the discharge pipe 11, thus altering the squeezing force exerted by the conical spiral rod body 15 on the biochemical sludge, thereby achieving efficient compression dewatering.
