[0040] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0041] As Figure 1 andFigure 2 The utility model discloses a coal slime water treatment device, which comprises a treatment box 10, a sludge water conveying part 20 and an extruding part 30. The treatment box 10 has a first end and a second end arranged oppositely in the horizontal direction. The treatment box 10 has a treatment cavity 11, a material inlet 12, a sludge discharge port 13 and a sewage discharge port 14, which are communicated with the treatment cavity 11 respectively. The material inlet 12 is arranged on the top of the first end of the treatment box 10. The sludge discharge port 13 is arranged on the side of the second end of the treatment box 10. The sewage discharge port 14 is arranged on the bottom of the treatment box 10. The sludge water conveying part 20 is arranged in the treatment box 10 and extends from the first end to the second end of the treatment box 10. The material inlet 12 is above the feeding end 201 of the sludge water conveying part 20. The discharging end 202 of the sludge water conveying part 20 extends to the sludge discharge port 13. The sludge water conveying part 20 comprises a conveying belt 21, and the conveying belt 21 is provided with a first filter hole 22. The extruding part 30 is arranged in the treatment box 10 and has an extruding end 301. The extruding end 301 is arranged above the sludge water conveying part 20 in a lifting manner. The extruding end 301 is used for applying a downward force to the material on the sludge water conveying part 20.

[0042] According to the technical scheme of the utility model, the sludge water conveying part 20 and the extruding part 30 arranged in the treatment box 10 can separate the sludge and the sewage in the coal slime water and discharge them respectively.

[0043] Specifically, the material inlet 12 is above the feeding end 201 of the sludge water conveying part 20. The coal slime water enters the treatment cavity 11 of the treatment box 10 through the material inlet 12, so that the coal slime water can fall on the conveying belt 21. The first filter hole 22 on the conveying belt 21 starts to play a filtering role. The larger solid particles in the coal slime water are intercepted on the conveying belt 21, and part of the water passes through the first filter hole 22 and falls to the bottom of the treatment cavity 11. During the conveying process of the conveying belt 21, the transmission action of the conveying belt 21 can be stopped intermittently. When the conveying belt 21 is in a static state, the extruding end 301 of the extruding part 30 descends above the conveying belt 21 to apply a downward force to the material, so that the water in the material is further squeezed out and discharged through the first filter hole 22. At this time, the sludge after dehydration is left on the conveying belt 21. Then, the extruding end 301 is lifted, and the conveying belt 21 continues to convey the sludge to the direction of the sludge discharge port 13. The sludge after dehydration is conveyed to the sludge discharge port 13 and discharged. The sewage falling to the bottom of the treatment cavity 11 is discharged through the sewage discharge port 14.

[0044] The first filter hole 22 arranged on the sludge water conveying part 20 in the treatment box 10 can realize the preliminary separation of the solid materials and water in the coal slurry water, the extrusion of the extrusion part 30 can further separate the solid materials and water in the coal slurry water, and the separation efficiency is effectively improved, the integrated arrangement of the material inlet 12, the sludge discharge port 13, the sewage discharge port 14, the sludge water conveying part 20 and the extrusion part 30 makes the treatment process more continuous, simplifies the operation process and improves the treatment efficiency.

[0045] In some embodiments of the present scheme, the extrusion part 30 is driven by a hydraulic cylinder, and the extrusion end 301 is provided with an extrusion roller shaft, and the outer surface of the extrusion roller shaft can be attached to the upper surface of the conveying belt 21, so as to better extrude the materials.

[0046] In some embodiments of the present scheme, the conveying belt 21 is provided with two, wherein the first conveying belt 21 is arranged obliquely directly below the material inlet 12, and the first conveying belt 21 is inclined downward along the direction from the first end to the second end of the treatment box 10; the second conveying belt 21 is arranged horizontally directly below the extrusion part 30, and the end of the second conveying belt 21 close to the first conveying belt 21 is located below the second end of the first conveying belt 21. The coal slurry water first falls on the obliquely arranged conveying belt 21, and then falls on the horizontally arranged conveying belt 21 after being conveyed by the obliquely arranged conveying belt.

[0047] Further, the coal slurry water treatment device further comprises a filtering part 40, the filtering part 40 is arranged below the sludge water conveying part 20, the filtering part 40 is provided with a second filter hole 41, and the filtering part 40 is located above the sewage discharge port 14. The above-mentioned arrangement can further filter the sewage treated by the first filter hole 22, the double filtration can further reduce the content of solid impurities in the sewage, and the solid-liquid separation efficiency is further improved, so as to subsequently discharge the sewage from the sewage discharge port 14 and subsequent treatment.

[0048] In the embodiments of the present scheme, the filtering part 40 can be a filter screen or a filter sieve.

[0049] As Figures 1 to 4As shown, further, the coal slurry water treatment device further comprises a partition 50, a flocculant feeding part 60 and a sewage conveying part 70. The partition 50 is arranged in the treatment box 10 to divide the treatment cavity 11 into a first chamber 111 and a second chamber 112 which are independent of each other in the height direction. The slurry water conveying part 20 is located in the first chamber 111, and the filtering part 40 is located in the second chamber 112. The flocculant feeding part 60 has a flocculant discharge port 61 which is in communication with the first chamber 111. The flocculant feeding part 60 feeds flocculant into the first chamber 111 through the flocculant discharge port 61. The top end of the sewage conveying part 70 is in communication with the bottom of the first chamber 111, and the bottom end of the sewage conveying part 70 is in communication with the second chamber 112 and located above the filtering part 40. The sewage conveying part 70 is used to convey sewage in the bottom of the first chamber 111 into the second chamber 112.

[0050] In the embodiment of the present scheme, the flocculant feeding part 60 is located below the slurry water conveying part 20 and in the lower part of the first chamber 111. After the coal slurry water is filtered by the slurry water conveying part 20, the filtered sewage falls into the bottom of the first chamber 111 for further flocculation treatment. The flocculant feeding part 60 feeds flocculant into the first chamber 111 through the flocculant discharge port 61, which can promote the aggregation of the tiny particles in the sewage to form larger flocs, further improving the solid-liquid separation effect. After the preliminary solid-liquid separation and flocculation in the first chamber 111, the solid substances are deposited at the bottom of the partition 50, and the sewage is conveyed to the second chamber 112 by the sewage conveying part 70 and falls into the filtering part 40 for secondary filtration, thereby improving the efficiency of the coal slurry water treatment and the purification effect of the sewage.

[0051] Further, the sewage conveying part 70 comprises a sewage conveying pipe 71 and an electromagnetic valve 72. The sewage conveying pipe 71 is arranged through the partition 50 in the height direction, and the top end of the sewage conveying pipe 71 has a spacing with the partition 50. The electromagnetic valve 72 is arranged on the sewage conveying pipe 71 to control the opening and closing of the sewage conveying pipe 71. The above arrangement enables the electromagnetic valve 72 to accurately control the opening and closing of the sewage conveying pipe 71, thereby conveying the sewage at the bottom of the first chamber 111 to the second chamber 112 in a timed and quantitative manner. Only the sewage which has been sufficiently flocculated and preliminarily separated into solid and liquid enters the second chamber 112 for secondary filtration. The spacing between the top end of the sewage conveying pipe 71 and the partition 50 can reduce the possibility of the flocculated precipitates being discharged into the second chamber 112 through the sewage conveying pipe 71.

[0052] As Figure 2As shown, the slurry water treatment device further includes an adsorption unit 80, which is disposed within the second chamber 112 and below the filter unit 40. The adsorption unit 80 can absorb and remove harmful components such as residual organic matter, inorganic matter, and heavy metal ions in the wastewater, thereby improving the purification of the wastewater. The adsorption unit 80 can also further remove tiny particles that the filter unit 40 fails to completely block, thereby enhancing the filtration effect of the wastewater. After being adsorbed by the adsorption unit 80, the wastewater is discharged through the wastewater outlet 14 at the bottom of the second chamber 112.

[0053] like Figures 1 to 3 As shown, the sludge water treatment device further includes a stirring portion 90, which is rotatably disposed in the first chamber 111 and is located below the sludge water conveying portion 20. The stirring portion 90 is used to stir the material on the baffle portion 50. This arrangement can improve the flocculation effect of the material in the first chamber 111.

[0054] Specifically, after the coal slurry is filtered through the first filter holes 22, the flocculant delivery unit 60 stirs the material through the flocculant discharge port, accelerating the mixing of the material and the flocculant and promoting the formation of flocs. The stirring unit 90 effectively enhances the flocculation effect, ensuring sufficient contact between the flocculant and the coal slurry, allowing small particles to agglomerate into larger flocs more quickly, thereby improving the efficiency and effectiveness of solid-liquid separation.

[0055] Furthermore, the flocculant delivery part 60 includes a flocculant delivery pipe 62, one end of which forms a flocculant discharge port 61, and the flocculant delivery pipe 62 is rotatably arranged in the first chamber 111 and is located below the sludge water conveying part 20; the stirring part 90 includes a stirring shaft 91, the stirring shaft 91 is a hollow structure, the stirring shaft 91 is coaxial with the flocculant discharge port 61, one end of the stirring shaft 91 is arranged at the flocculant discharge port 61 and is fixedly connected to the flocculant discharge port 61, and a flocculant discharge hole 92 is provided on the side of the stirring shaft 91.

[0056] In the embodiment of this solution, a hollow stirring shaft 91 is used as a channel for dispensing flocculants. This allows the flocculants to be evenly dispersed throughout the coal slurry water in the first chamber 111 while stirring, thereby improving the flocculant's flocculation effect. Specifically, the flocculant dispensing pipe 62 is capable of rotating synchronously with the stirring shaft 91. The flocculant is discharged from the flocculant dispensing pipe 62 into the hollow stirring shaft 91 via the flocculant discharge port 61. During the rotation of the stirring shaft 91, the flocculant is evenly discharged into the material through the flocculant discharge holes 92 on the side of the stirring shaft 91. Simultaneously, the rotation of the stirring shaft 91 promotes thorough mixing of the flocculant and the material, thereby improving the utilization rate of the flocculant and the flocculation effect.

[0057] Further, the flocculant feeding part 60 further comprises a flocculant transfer part 63 and a flocculant conveying part 65. The flocculant transfer part 63 is used for containing flocculant. The end of the flocculant feeding pipe 62 away from the flocculant discharge port 61 is rotatably arranged in the flocculant transfer part 63. The end of the flocculant feeding pipe 62 away from the flocculant discharge port 61 is provided with a flocculant inlet 64. The flocculant conveying part 65 is used for conveying flocculant into the flocculant transfer part 63, so that the flocculant is conveyed into the flocculant feeding pipe 62 through the flocculant transfer part 63.

[0058] Specifically, when the flocculant conveying part 65 conveys flocculant into the flocculant transfer part 63, the flocculant in the flocculant transfer part 63 flows into the flocculant feeding pipe 62 through the flocculant inlet 64, and then is uniformly discharged into the first chamber 111 through the flocculant discharge hole 92 arranged on the side of the stirring shaft 91. The flocculant conveying part 65 can control the dosage of flocculant feeding, realize accurate control of the dosage of flocculant, and improve the controllability of flocculant feeding.

[0059] In the embodiment of the present scheme, the end where the flocculant inlet 64 is located is in the flocculant transfer part 63 and is immersed in the flocculant. The flocculant inlet 64 is arranged at a position such that the flocculant can be stably and sufficiently squeezed into the flocculant feeding pipe 62.

[0060] In the embodiment of the present scheme, the flocculant conveying part 65 comprises a flocculant storage tank 651, a flocculant conveying pipe 652, and a flocculant conveying pump 653. The two ends of the flocculant conveying pipe 652 are respectively communicated with the flocculant storage tank 651 and the flocculant transfer part 63. The flocculant conveying pump 653 is arranged on the flocculant conveying pipe 652. The flocculant conveying pump 653 extracts flocculant from the flocculant storage tank 651 and conveys the flocculant into the flocculant transfer part 63 through the flocculant conveying pipe 652.

[0061] Further, the flocculant transfer part 63 is arranged in the treatment tank 10. The flocculant inlet 64 is arranged on the side wall of the end of the flocculant feeding pipe 62 away from the flocculant discharge port 61. The end of the flocculant feeding pipe 62 away from the flocculant discharge port 61 is a blocked end. The blocked end sequentially penetrates through the flocculant transfer part 63 and the treatment tank 10 and is located outside the treatment tank 10. The sludge treatment device further comprises a driving part 100. The driving part 100 is arranged on the outer side wall of the treatment tank 10. The driving part 100 is drivingly connected with the blocked end of the flocculant feeding pipe 62, so as to rotate the flocculant feeding pipe 62. Specifically, during the flocculant feeding process, the driving part 100 is started to drive the flocculant feeding pipe 62 to rotate. The flocculant feeding pipe 62 in turn drives the stirring shaft 91 to rotate. Meanwhile, the flocculant enters the flocculant feeding pipe 62, and then the flocculant enters the stirring shaft 91 and is fed.

[0062] In the embodiment of the present scheme, the two ends of the flocculant transfer part 63 are sealed with rolling bearings, and the flocculant feeding pipe 62 is matched with the flocculant transfer part 63 through the rolling bearings, so that the flocculant feeding pipe 62 can pass through the flocculant transfer part 63 and rotate. The arrangement of the rolling bearings ensures the stability of the flocculant feeding pipe 62 during rotation, reduces the friction between the flocculant feeding pipe 62 and the flocculant transfer part 63, effectively avoids vibration or position deviation caused by rotation, and ensures uniform distribution of the flocculant.

[0063] Further, the stirring part 90 further comprises stirring blades 93 and propellers 94, the stirring blades 93 are arranged on the stirring shaft 91, and the propellers 94 are arranged on the stirring blades 93. The stirring blades 93 and the propellers 94 can effectively enhance the stirring effect of the stirring part 90, so that the flocculant and the coal slime water are more fully contacted and mixed, the formation of the flocculation is accelerated, and the efficiency of the solid-liquid separation is improved.
