Description

Technical Field

[0001] The present invention relates to the technical field of mud-water mixture treatment, in particular to a rapid screening device based on low-temperature anaerobic ammonia oxidation particles. Background Art

[0002] In order to adapt to the increasing requirements of the current miniaturization of mud-water mixture treatment technology, particle screening has also been continuously improved with the improvement of indicators. The mesh screening equipment is one of the main equipment. By providing better interception efficiency, the particles of target particle size in the mud-water mixture can be efficiently separated to achieve the purpose of mud-water mixture particle optimization, which ensures the stable operation of particle-based mud-water mixture treatment process equipment.

[0003] Existing screen screening equipment, whether imported or domestic, generally uses double-sided chains to drive the filter screen assembly for rotational motion to filter the screen residue from the mud-water mixture. After the residue is lifted, the screen residue is carried into the intermediate water tank through gravity, flushing water, and rotating brushes. Since the water and screen residue are in a mixed state, an external high-pressure dewatering press is generally required. Screen screening solves the problem of traditional screening interception efficiency, but its own comprehensive power is much higher than that of traditional screening. At the same time, the amount of flushing water is large. Although reclaimed water is used, the stability and maintenance of the flushing system are very obvious problems due to the high impurities in the water. If a filter is used, the equipment cost will increase. At the same time, it is difficult to eliminate clogging and entanglement problems when flushing the screen, so the design will also add configurations such as cleaning brush rollers and high-pressure particle selectors. This results in further increases in equipment cost and total power.

[0004] In the mud-water mixture treatment process, the low temperature environment and the treatment of anaerobic ammonia oxidation particles have always been the difficulties in the pretreatment link. Traditional screen screening equipment often has many problems when facing particles under low temperature conditions. The original double-sided chain drives the filter screen assembly to perform rotary motion screen screening. In a low temperature environment, the flushing water system is prone to freezing, clogging and other problems, and the retention effect of anaerobic ammonia oxidation particles is not good. The use of flushing water not only increases the operating cost of the equipment, but may also lead to the loss of particles and secondary pollution. At the same time, due to the particularity of anaerobic ammonia oxidation particles, conventional flushing methods are difficult to effectively remove particles attached to the filter screen, which can easily cause the filter screen to be clogged, thereby affecting the normal operation and treatment efficiency of the equipment. Therefore, there is an urgent need for a new filter screen screening purifier for low temperature and anaerobic ammonia oxidation particles to solve the many problems faced by existing equipment under this specific process condition. Summary of the Invention

[0036] Compared with the prior art, the beneficial effects of the present invention are embodied in the following aspects:

[0037] 1. The present invention has a reasonable structural design and a fixed filter tube structure, which reduces the filter mesh surface required for conventional screen plates, reduces equipment costs, avoids wear and tear, and improves the operating stability of the equipment. The screen plates of the filter tube structure do not require sealing, which reduces the use of screen seals, reduces operating risks, and reduces equipment costs.

[0038] 2. The present invention is easy to operate and adopts a mechanical particle selection structure, which avoids the conventional screen plate screening and washing particle selection, reducing the operating cost and manufacturing and installation cost of the equipment. Especially in low temperature environments, there is no need to worry about the freezing problem of the flushing water system. At the same time, it effectively prevents the loss of anaerobic ammonia oxidation particles. The mechanical particle selection structure and the screen plate are in a vertical shearing motion, which effectively prevents the aggregation and entanglement of screen residue and particles, thereby improving the processing efficiency of the equipment.

[0039] 3. The technical solution of the present invention uses a filter array that can optimize operation based on the actual screen residue and particle enrichment, thereby achieving energy conservation, reducing wear of related filter components, and extending the service life of the equipment. It can also better adapt to the treatment requirements of low temperatures and anaerobic ammonium oxidation particles;

[0040] 4. The dynamic adjustment mechanism of the filter holes of the present invention is such that each dynamic adjustment matching hole and each integrated filtration micropore can be coaxially aligned and connected to form a filtration channel. By adjusting the overlapping area of the dynamic adjustment matching hole and the integrated filtration micropore, the cross-sectional size of the filtration channel can be adjusted to accommodate screen residues and particles of various actual particle sizes.

[0077] In the actual application process of the present invention, Figure 1 As shown, the mud-water mixture in the pre-treatment flow channel 10 flows from left to right, the left side of the sub-screen support housing 111 is called the upstream end, and the right side of the sub-screen support housing 111 is called the downstream end;

[0078] During the circulation of the mud-water mixture in the pretreatment circulation channel 10, it enters the interior of the sub-screening support and containing shell 111 through multiple sub-screening main input pipes 112, and the mud-water mixture is collected in the sub-screening support and containing shell 111 and the water level is gradually raised. During the water level rising process in the sub-screening support and containing shell 111, the mud-water mixture enters the interior of the comprehensive filter tube 22 through the lower end of the comprehensive filter tube 22, and the mud-water mixture entering the interior of the comprehensive filter tube 22 flows from the inside to the outside through the comprehensive filter micropores 220, thereby filtering the mud-water mixture, and the screening residue and particles in the mud-water mixture will be intercepted and retained in the interior of the comprehensive filter tube 22, and the filtered mud-water mixture enters the interior of the filter tube combination containing shell 21, and the filtered mud-water mixture in the filter tube combination containing shell 21 is discharged to the downstream end of the sub-screening support and containing shell 111 through the sub-screening main output pipe 113, and the filtered mud-water mixture continues to circulate in the pretreatment circulation channel 10 and enters the subsequent mud-water mixture treatment process;

[0079] The water level monitoring sensors 51 are numbered from bottom to top as S1, S2, S3, S4, and S5. Assuming that the integrated filter tube 22 is operating in normal filtration processing, the water level balance in the sub-screening support housing 111 is between S3 and S4. When the screening residue and particles in the integrated filter tube 22 are enriched to a certain extent, the water flow through the integrated filter tube 22 will decrease, and the water level in the sub-screening support housing 111 will continue to rise until the water level monitoring sensor 51 numbered S4 detects a water level signal, indicating that the integrated filter tube 22 needs to be cleaned.

[0080] When the screenings and particles accumulated inside the integrated filter tube 22 cause the filtering performance of the integrated filter tube 22 to decrease, the screenings and particles intercepted inside the integrated filter tube 22 are cleaned by the filter particle selection mechanism 23;

[0081] The inner rod of the particle-preferred driving telescopic rod 237 extends to drive the particle-preferred driving sliding cylinder 236, the driving rod linkage plate 233 and the plurality of particle-preferred driving push rods 232 to move downward in the vertical direction. The plurality of particle-preferred driving push rods 232 then drive the particle-preferred shearing ring shells 231 to move from top to bottom in the integrated filter tube 22. The edge structure of the lower end edge of the particle-preferred shearing ring shell 231 is used to shovel off the screening residue and particles attached to the inner wall of the integrated filter tube 22, and under the push of the particle-preferred shearing ring shell 231, the screening residue and particles are pushed out from the lower end of the integrated filter tube 22.

[0082] Then the particle-preferred driving inner rod of the telescopic rod 237 is retracted, so that the particle-preferred shear ring shell 231 is returned to the top of the integrated filter tube 22;

[0083] The screenings and particles cleaned out from the integrated filter tube 22 will accumulate at the bottom of the screening support housing 111;

[0084] The siphon discharge mechanism 30 is used to discharge the screenings and particles accumulated at the bottom of the screening support and accommodating shell 111, and the particle separation mechanism 40 is used to compress and dehydrate the screenings and particles;

[0085] Simultaneously, the siphon discharge control valves 311 at both ends of the siphon discharge conveying pipe 31 are opened. Under the action of gravity, the mud-water mixture mixed with the screenings and particles will pass through the siphon discharge conveying pipe 31 into the particle separation holding box 41. After the particle separation holding box 41 is filled, the siphon discharge control valves 311 at both ends of the siphon discharge conveying pipe 31 are simultaneously closed.

[0086] In the initial state, the particle separation and extrusion slider 42 is located inside the particle separation holding box 41 at a side away from the siphon discharge conveying pipe 31. After the particle separation holding box 41 is filled with screenings and particles, the inner rod of the particle compression driving rod 423 extends and drives the particle separation and extrusion slider 42 to move inside the particle separation holding box 41 through the particle discharge push rod 434, thereby squeezing the screenings and particles. The moisture in the screenings and particles will be squeezed out and enter the separation mud and water mixture collection shell 411 through the separation mud and water mixture discharge hole 410. The mud and water mixture in the separation mud and water mixture collection shell 411 can finally be discharged from the separation mud and water mixture output pipe 412.

[0087] In the initial state, the particle discharge baffle 432 blocks the lower side of the compressed particle discharge port 431, so that the compressed particle discharge port 431 is in a closed state, and the compressed particle push plate 435 is at the top position in the particle separation and holding box 41;

[0088] After the screen residue and particles are compressed, they are located at the compressed particle discharge port 431. The inner rod of the baffle opening and closing driving rod 438 extends to drive the particle discharge baffle 432 away from the compressed particle discharge port 431, so that the compressed particle discharge port 431 is in an open state.

[0089] Then the inner rod of the particle discharge driving rod 436 extends to drive the particle discharge push rod 434 and the compressed particle discharge push plate 435 to move from top to bottom. Under the push of the compressed particle discharge push plate 435, the compressed screen residue and particles are pushed out from the compressed particle discharge port 431.

[0090] Between each filter hole adjustment fitting tube 241 and the integrated filter tube 22, each dynamic adjustment fitting hole 240 and each integrated filter micropore 220 can be coaxially aligned and connected at the same time. When the dynamic adjustment fitting hole 240 and the integrated filter micropore 220 are connected, a filter channel is formed together. By adjusting the overlapping area of the dynamic adjustment fitting hole 240 and the integrated filter micropore 220, the cross-sectional size of the filter channel can be adjusted to accommodate screen residues and particles of various actual particle sizes.

[0091] The extension or retraction of the inner rod of the dynamic adjustment driving rod 245 can drive the dynamic adjustment sliding cylinder 244, the dynamic adjustment push rod 242 and the filter hole adjustment matching tube 241 to move in the vertical direction, thereby controlling the overlapping area between each dynamic adjustment matching hole 240 and each integrated filtration micropore 220.
