Description

Technical Field

[0001] The invention relates to the technical field of precipitation, in particular to a grid-shaped high-efficiency precipitation machine. Background Art

[0002] As an important equipment in the sewage treatment process, the sewage sedimentation machine mainly removes large suspended particles, organic matter, inorganic matter and some colloidal substances in the sewage by physical sedimentation, thereby reducing the load of subsequent treatment processes and improving the overall sewage treatment efficiency and water quality. Among them, suspended matter in sewage such as silt, gravel, animal and plant remains, etc., can be mostly removed through the sedimentation of the sedimentation machine. As the front-end treatment equipment for sewage treatment, the sedimentation machine can effectively reduce the load of subsequent biological treatment units (such as activated sludge method, biofilm method, etc.) by removing most of the suspended matter and improve the treatment efficiency.

[0003] The working principle of sewage sedimentation machine is usually based on the principle of gravity sedimentation, that is, utilizing the density difference between suspended matter and water in sewage to naturally sink to the bottom of the sedimentation tank under the action of gravity, thereby achieving solid-liquid separation.

This laminar flow state helps to reduce turbulence and disturbance in the water flow, making it easier for suspended particles to settle. However, the settled suspended particles will accumulate at the lower end of the sewage sedimentation machine, and when the suspended particles are cleaned, it will have a stirring effect, further mixing the settled suspended particles with the water, and the required cleaning effect cannot be achieved.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-4The present invention provides a technical solution: a grid-shaped high-efficiency sedimentation machine, comprising a plurality of sedimentation boxes 1 arranged obliquely, wherein the end faces of the plurality of sedimentation boxes 1 are contacted with each other, and both ends of the sedimentation boxes 1 are through-set so that water can move along the sedimentation boxes 1, and a separation layer 2 for sealing is fixed between the sedimentation boxes 1 and the adjacent sedimentation boxes 1, and the separation layer 2 seals the sedimentation boxes 1 on both sides to prevent water from moving outward, and a plurality of partitions 12 are arranged inside the sedimentation boxes 1, and the plurality of partitions 12 divide the internal space of the sedimentation boxes 1, so that the water flow forms a stable laminar flow state when passing through the partitions 12. This laminar flow state helps to reduce turbulence and disturbance in the water flow, making it easier for suspended particles to settle. A plurality of separation parts 3 are also provided, which are respectively clamped between two baffles 12 and are used to receive and remove the suspended particles in the sedimentation tank 1. It should be noted that the water in the sedimentation tank 1 settles layer by layer, so that the settled suspended particles will remain inside the sedimentation tank 1. Therefore, it is necessary to clean the remaining suspended particles to avoid the gradual accumulation of suspended particles and to prevent the suspended particles from moving to the sedimentation tank 1 of the next layer after accumulation.

[0038] The separation part 3 includes a connecting block 31, which is fixedly embedded in the lower end of the sedimentation box 1 from bottom to top; it also includes a blocking shaft 32, which is slidably arranged with the connecting block 31, and the blocking shaft 32 is used to open and close the space between two adjacent partitions 12, and the blocking shaft 32 moves upward along the connecting block 31, so that the blocking shaft 32 blocks the space between the two partitions 12, so as to achieve the effect of cutting off the water, because the subsequent operation needs to clean the suspended particles on the receiving layer 33, which is easy to produce a stirring effect; the separation part 3 also includes a receiving layer 33, which is hinged on the connecting block 31, and it can change horizontally and tilted, and is used to clean the suspended particles. The receiving layer 33 is used to block the suspended particles at its upper end to reduce the deposition of suspended particles in the sedimentation box 1. It should be noted that the receiving layer 33 after tilting can dump the suspended particles, and the blocking shaft 32 needs to cut off the water when dumping.

[0039] like Figure 1 As shown, the effect of step-by-step sedimentation is more obvious. The end faces of several sedimentation boxes 1 and adjacent sedimentation boxes 1 are half overlapped, and the heights of the sedimentation boxes 1 arranged along the direction of the water flow are gradually increased. It should be noted that the water is moved upward step by step, and the upper half of each sedimentation box 1 is connected with the lower half of another sedimentation box 1. Even if the suspended particles move to the next sedimentation box 1, they can be quickly deposited in the favorite sedimentation box 1 under the action of gravity, and will not continue to move upward to the next sedimentation box 1, thereby maximizing the sedimentation effect.

[0040] like Figure 2As shown, the arranged sedimentation boxes 1 are connected, and the two sides of the separation layer 2 are respectively connected with the ends of the sedimentation boxes 1 on both sides, and the sides of the separation layer 2 are fixed to the sedimentation boxes 1 by bolts, so that the separation layer 2 fixes the sedimentation boxes 1 on both sides;

[0041] like Figure 2 As shown, the arranged sedimentation boxes 1 are controlled to transmit water and make the water move from the upper half of one sedimentation box 1 to the lower half of the next sedimentation box 1. The middle position inside the separation layer 2 is set as a connecting cavity 21. The upper and lower positions of the connecting cavity 21 are provided with barrier layers 22. The upper and lower barrier layers 22 are integrally arranged with the separation layer 2. The upper and lower barrier layers 22 are staggered and respectively abut against the end faces of the sedimentation boxes 1 on both sides. The barrier layers 22 are used to block the non-overlapping parts of the sedimentation boxes 1 and control the water to move along the arranged sedimentation boxes 1 and move upward step by step.

[0042] The sedimentation box 1 is coordinated with the next sedimentation box 1 so that water moves from the upper part of the sedimentation box 1 to the lower part of the next sedimentation box 1. The area of ​​the connecting cavity 21 is set to be half of the end surface area of ​​the sedimentation box 1, so that the area of ​​water passing through the two sedimentation boxes 1 is limited. At the same time, the separation layer 2 and the barrier layer 22 are both provided with sealing rubber to avoid leakage caused by the increase of water pressure due to the step-by-step upward movement of water.

[0043] like Figure 3 As shown, in order to facilitate the disassembly of the partition 12, metal layers 11 are arranged in groups of two on the inner wall of the upper end of the sedimentation box 1, and the partition 12 is clamped between the metal layers 11 on both sides, and the upper and lower sides of the partition 12 are respectively against the upper and lower inner walls of the sedimentation box 1. It should be noted that the metal layer 11 arranges the partitions 12 at uniform intervals and controls the position so that the water can form a stable laminar state, which can maintain a stable laminar state even when the water flow changes.

[0044] like Figure 5 As shown, the connecting block 31 is rectangular, and its width is equal to the width between the two layers of partitions 12. The connecting block 31 is made of metal, which prevents the connecting block 31 from deformation and has a relatively long service life. The connecting block 31 is provided with holes from bottom to top for the suspended particles to fall, and can also allow water to pass through. A layer of rubber sleeve 313 is fixed in the hole, and the lower end of the rubber sleeve 313 is blocked with a rubber plug 314, and the rubber plug 314 can be taken out. It should be noted that the rubber plug 314 can make the rubber sleeve 313 present the function of opening and closing, so that water can flow outward from the rubber sleeve 313, and can also be closed and sealed.

[0045] like Figure 5As shown, the inclination angle of the receiving layer 33 needs to be changed so that the suspended particles on the receiving layer 33 can slide along the receiving layer 33 and flow out of the hole together with the water. Therefore, a threaded hole 311 is also provided at the lower end of the connecting block 31, and a fastening bolt 312 is threadedly connected to the threaded hole 311. The fastening bolt 312 is rotated to squeeze it with the receiving layer 33, wherein the upper end of the fastening bolt 312 is circular. It should be noted that the circular fastening bolt 312 end is squeezed with the receiving layer 33, which is smoother and also avoids damage to the receiving layer 33. Rotating the fastening bolt 312 can squeeze its upper end with the receiving layer 33, and the receiving layer 33 can change from horizontal to inclined. The inclined receiving layer 33 is used to dump the suspended particles. It should be noted that the inclination change of the receiving layer 33 can make the suspended particles move and process the deposited suspended particles.

[0046] like Figure 7 As shown, in order to restrict the suspended particles on the receiving layer 33, the receiving layer 33 is arranged to contact the inner wall of the lower end of the sedimentation box 1 when horizontal, and a receiving groove 331 for holding the suspended particles is provided at the upper end of the receiving layer 33. The two sides of the receiving layer 33 are respectively in contact with the partitions 12 on both sides. It should be noted that the two sides of the receiving layer 33 are in contact with the partitions 12 on both sides so that the inner wall of the lower end of the sedimentation box 1 is exposed to the minimum extent, thereby reducing the deposition of suspended particles on the inner wall of the lower end of the sedimentation box 1.

[0047] like Figure 7 As shown, the edge of the receiving groove 331 of the receiving layer 33 is set in the form of a bevel 332, and the bevel 332 extends obliquely downward into the receiving groove 331. The upper end of the bevel 332 contacts the partition 12 on the side, and the lower end contacts the inner wall of the side of the receiving groove 331. It should be noted that the suspended particles deposited downward will move along the bevel 332 of the receiving groove 331, reducing the deposition of suspended particles on the edge position, and relatively keeping the suspended particles in the receiving groove 331.

[0048] like Figure 7As shown, in order to facilitate the dumping of the deposited suspended particles, the lower end of the receiving layer 33 is further provided with an inclined groove 333 extending obliquely to the inside of the receiving groove 331. The inclined groove 333 is arranged obliquely upward along the direction of the water flow. It should be noted that when the receiving layer 33 is inclined, it is inclined downward along the direction of the water flow. Under the action of the water flow, it moves obliquely downward along the inclined groove 333 to flush out the deposited suspended particles. The inclined lower end position of the inclined groove 333 is arranged with a notch 334 with an increased area. When tilted, the amount of water entering the slot 334 increases. It should be noted that when the receiving layer 33 is tilted, the slot 334 increases the amount of water flowing to the end of the inclined groove 333, so that the water flows faster along the inclined groove 333 to better impact the suspended particles. It should also be noted that when the receiving layer 33 is horizontal, the water flows horizontally along the receiving layer 33, and the inclined groove 333 is tilted upward along the direction of the water flow. Therefore, the suspended particles will not move to the depth of the inclined groove 333 under the condition of water flow.

[0049] like Figure 5 The cam 32 is provided with a protruding portion 322 on the outside of the blocking shaft 32, and the blocking shaft 32 is located on the side of the connecting block 31, and the protruding portion 322 cooperates with the side of the connecting block 31 to maintain stability during the up and down movement. The lower end of the sedimentation box 1 is fixed with a rubber sleeve 315, and the rubber sleeve 315 is sleeved with the blocking shaft 32 to maintain a seal. It should be noted that during the up and down movement of the blocking shaft 32, the seal between the rubber sleeve 315 and the blocking shaft 32 is maintained to avoid water leakage. The lower end of the blocking shaft 32 has an integrally provided pulling point 321, and the pulling point 321 is pulled to control the up and down movement of the blocking shaft 32. The two sides of the blocking shaft 32 are respectively in contact with the partitions 12 on both sides, and the upper end thereof extends upward to contact with the inner wall of the sedimentation box 1, so as to achieve the effect of fitting and realize the effect of cutting off the water flow.

[0050] The upper end of the blocking shaft 32 is in a "convex" shape, which can cut off the water flow. The upper ends of both sides are provided with end faces 324 and are in contact with the metal layer 11. The side of the blocking shaft 32 close to the connecting block 31 has an integrally provided end face 323. The position of end face 323 is lower than that of end face 324, and end face 323 is used to abut against the connecting block 31. It should be noted that the blocking shaft 32 moves upward to make the water flow end face 324 contact the metal layer 11 to cut off the water flow. On the contrary, it moves downward to make the end face 323 contact the connecting block 31 to reach the limit. At the same time, the position of end face 323 is lower than that of end face 324, so that end face 324 can always be located in the sedimentation box 1 to maintain the seal between the rubber sleeve 315 and the blocking shaft 32.

[0051] The working principle of the present invention is as follows: through a plurality of sedimentation boxes 1, water is allowed to precipitate step by step when passing through the middle, and a detachable partition 12 is provided to separate the water, so that the water flow forms a stable laminar flow state when passing through the partition 12, reducing turbulence and disturbance in the water flow, making it easier for suspended particles to settle. And under the action of gravity, the suspended particles gradually move downward, and the passing water moves from the upper half of the sedimentation box 1 to the next sedimentation box 1, and the suspended particles that settle downward to the greatest extent move to the next sedimentation box 1, and are filtered to the greatest extent.

[0052] The suspended particles that settle downward will accumulate at the upper end of the receiving layer 33, and will contact the inner wall of the sedimentation box 1 to the minimum extent. The fastening bolts 312 are rotated to make the fastening bolts 312 abut against the receiving layer 33 at the upper end, and the receiving layer 33 is tilted, and the blocking shaft 32 is pushed upward to seal the position between the two partitions 12 to prevent water from moving through, and the rubber plug 314 is removed to make the rubber sleeve 313 communicate with the inside of the sedimentation box 1, and the suspended particles adhered to the receiving layer 33 can move under the action of water and move out of the rubber sleeve 313, so that the suspended particles are cleaned;

[0053] Secondly, the receiving groove 331 provided on the receiving layer 33 is used to limit the suspended particles, and the inclined groove 333 provided can allow water to pass through the inclined groove 333, pushing the suspended particles downward along the inclined groove 333 to ensure that the suspended particles are cleaned, and the groove 334 can increase the water intake of the inclined receiving layer 33, so that the speed of water moving from the inclined groove 333 is accelerated, the pushing effect on the suspended particles is increased, and the suspended particles are separated effectively. Finally, the receiving layer 33 is reset, and the blocking shaft 32 also moves downward and resets, so that the water can be precipitated and graded again.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
