Description

Technical Field

[0001] The invention relates to the technical field of solid-liquid separation of coal mine waste slag, and in particular to a scraper-type coal sludge water solid-liquid separator. Background Art

[0002] Underground coal slime water is wastewater generated during coal mining. The solid particles carried by underground coal slime water will affect normal production after silting up in the ditches in the horizontal tunnels, the head (or tail) of the raw coal belt conveyor, the sedimentation tank and the water tank, and seriously occupy the effective volume of the water tank, resulting in insufficient ability of the mine to resist floods and posing a greater threat to safe production.

[0003] The commonly used dredging measure at present is a combination of manual dredging and dredging with a single auxiliary equipment. It is not only labor-intensive and inefficient, but also will lead to increased wear of multi-stage pumps and increased equipment failure rate if the dredging is not thorough, and ultimately lead to a deterioration in the water tank's ability to resist floods, seriously threatening the personal safety of underground workers. Summary of the invention

[0004] The purpose of the present invention is to provide a scraper type coal slime water solid-liquid separator, which is based on a box component and a scraper assembly. It can not only realize the sedimentation of coal slime in coal slime water, but also utilize a mobile diversion assembly that can automatically reciprocate to make the coal slime water evenly distributed in the sedimentation box, and cooperate with the use of a flip arc plate assembly and a scraper cleaning assembly. It can not only scrape and dredge the coal slime settled to the bottom of the caisson, but also automatically clean the components used in the operation, thereby improving work efficiency and reducing labor costs, and also increasing the service life of the equipment through automatic cleaning.

[0005] The object of the present invention is achieved through such a technical solution, a scraper type coal slurry water solid-liquid separator, comprising a box component, a scraping assembly, a mobile diversion assembly, a flip arc plate assembly and a scraper cleaning assembly, the box component comprises a sedimentation box and a coal slurry discharge hopper, the scraping assembly comprises a scraping chain and a scraper plate, the mobile diversion assembly comprises a water accumulation partition plate, the flip arc plate assembly comprises an arc-shaped flap, and the scraper cleaning assembly comprises a cleaning belt and a rolling bevel gear;

[0006] The sedimentation box is a cavity structure with a sloped bottom surface, the coal slime discharge hopper is connected to the upper end of the slope of the sedimentation box, the scraper chains are laid in pairs on the inner bottom surface of the sedimentation box, and the scraper plates are arranged horizontally and connected between the scraper chains;

[0007] A diversion box capable of automatic reciprocating movement is slidably connected to one side of the top of the sedimentation box, and water separation plates are fixed in pairs in the inner cavity of the diversion box, and an arc-shaped flap is screwed to the bottom of the diversion box;

[0008] A cleaning frame is screwed on the inside of the coal slime discharge hopper, rolling rollers are screwed on both sides of one end of the cleaning frame, the cleaning belt is sleeved between the rolling rollers, a second conversion internal bevel gear is screwed on one side of the main body of the coal slime discharge hopper, the second conversion internal bevel gear is connected to the scraper chain transmission, and a rolling bevel gear is inserted into the outer shaft end of one group of rolling rollers.

[0009] The use process of the technical solution of the present invention is as follows:

[0010] The part below the slope of the inner cavity of the sedimentation box is used to hold the coal slurry water to be precipitated, and the mobile diversion component can make the coal slurry water evenly precipitate on the inner cavity bottom surface of the sedimentation box;

[0011] When the diverter box is used to inject coal slurry water into the inner cavity of the sedimentation box, the arc-shaped flap is flipped upward into place. At this time, the arc-shaped flap is used as the bottom surface of the diverter box, and the water injection end is located in the middle of the diverter box just above, so that the coal slurry water can first enter the cavity formed by the water accumulation partition plate and the arc-shaped flap. After filling the cavity formed by the water accumulation partition plate and the arc-shaped flap, it will overflow from the top of the water accumulation partition plate, and be evenly discharged laterally outward from the gap formed by the bottom end of the side wall of the diverter box and the outer arc surface of the arc-shaped flap. In this process, the diverter box is in a state of reciprocating movement within a certain range, so that the coal slurry water discharged from the diverter box can be evenly distributed in the inner cavity of the sedimentation box.

[0012] The coal slurry water is precipitated in the inner cavity of the sedimentation box to form coal slurry, the upper water in the sedimentation box is drained, and the driving mechanism connected to the scraping chain is started to drive the scraping chain to roll, so that the scraping plate scrapes the bottom surface of the inner cavity of the sedimentation box, and the coal slurry deposited on the bottom surface of the inner cavity of the sedimentation box is scraped to the coal slurry discharge hopper, and discharged from the outlet at the bottom of the coal slurry discharge hopper;

[0013] During this process, the cleaning rack will rotate to a position where it does not interfere with the inflow and outflow of the coal slime discharge hopper, and will not interfere with the downward discharge of the coal slime from the coal slime discharge hopper;

[0014] By automatically flipping the arc-shaped flap to face downward, the scraping plates connected between the scraping chains on the top layer can contact the outer arc surface of the arc-shaped flap. The scraping action of the scraping plates and the rotation of the arc-shaped flap within a certain range after the outer arc surface faces downward can scrape away the coal slime attached to the outer arc surface of the arc-shaped flap.

[0015] By rotating the cleaning frame to the position where the cleaning belt is directly opposite to the inlet of the coal slime discharge hopper, the bristles on the outside of the cleaning belt with a certain elasticity will protrude into the inner cavity of the sedimentation box and come into friction contact with the scraper plate, and the rolling bevel gear and the second conversion inner bevel gear will mesh in place. As the scraper chain rolls and drives the scraper plate to move, the cleaning belt can be synchronously driven to form a rolling state. The relative movement between the scraper plate and the cleaning belt bristles can automatically clean the coal slime attached to the scraper plate.

[0016] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0017] (1) The present invention provides a reciprocating diversion box on one side of the top of the sedimentation box. After the arc-shaped flap is turned upward to the right position, the outer arc surface of the arc-shaped flap and the diversion box form an integral cavity, and the paired water-accumulating partition plates can form a diversion effect on the coal slurry water, so that the coal slurry water first enters the cavity formed by the water-accumulating partition plate and the arc-shaped flap. The height difference between the top of the water-accumulating partition plate and the top of the side wall of the diversion box can form a uniform lateral distribution effect of the coal slurry water along the lateral direction of the diversion box. In combination with the automatic reciprocating movement of the diversion box, the coal slurry water can be evenly distributed in the inner cavity of the sedimentation box.

[0018] (2) The scraper plate of the present invention can not only scrape the coal slime deposited on the bottom surface of the inner cavity of the sedimentation box, but also automatically clean the outer curved surface of the used curved flap after the curved flap is turned downward to the outer curved surface of the curved flap and contacts the scraper plate connected to the scraping chain on the top layer;

[0019] (3) The present invention further provides a scraper cleaning assembly inside the coal slime discharge hopper. Through the automatically rotatable cleaning frame, the cleaning belt can be placed in a position that does not interfere with the discharge of coal slime from the coal slime discharge hopper. When necessary, the cleaning belt can be moved to a position directly opposite to the inlet of the coal slime discharge hopper, and the rolling bevel gear and the second conversion inner bevel gear can be synchronously meshed. Thus, the scraper chain can be used to drive the scraper plate to move while driving the cleaning belt to automatically clean the scraper plate. This not only forms a solid-liquid separation of coal slime water, but also can automatically clean related components in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] like Figure 1-Figure 15 As shown, a scraper-type coal sludge water solid-liquid separator, the sedimentation box 101 in the box component 1 is a cavity structure with a slope on the bottom surface, the coal sludge discharge hopper 104 is connected to the upper end of the slope of the sedimentation box 101, and is communicated with the inner cavity of the sedimentation box 101, the scraper chains 204 are laid in pairs on the inner bottom surface of the sedimentation box 101, and can roll synchronously, the scraper plates 207 are arranged horizontally and connected between the scraper chains 204, and the scraper chains 204 can roll according to the bottom surface of the sedimentation box 101 as a path, and the scraper plates 207 connected between the scraper chains 204 at the bottom layer are in friction contact with the bottom surface of the sedimentation box 101;

[0041] A diversion box 301 capable of automatic reciprocating movement is slidably connected to one side of the top of the sedimentation box 101, and water partition plates 307 are fixed in pairs in the inner cavity of the diversion box 301, and the arc-shaped flap 402 is screwed to the bottom of the diversion box 301. The bottom end structure of the water partition plate 307 matches the outer arc surface of the arc-shaped flap 402, and after the arc-shaped flap 402 is flipped upward into place, a certain gap is left between the outer arc surface of the arc-shaped flap 402 and the bottom end of the side wall of the diversion box 301, and the arc-shaped flap 402 can also be flipped downward to the outer arc surface to frictionally contact with the scraper plate 207 connected to the scraper chain 204 on the top layer;

[0042] A cleaning frame 502 is screwed to the inside of the coal slime discharge hopper 104, and rolling rollers 510 are screwed to both sides of one end of the cleaning frame 502, and the cleaning belt 503 is sleeved between the rolling rollers 510. A second conversion inner bevel gear 519 is screwed to one side of the main body of the coal slime discharge hopper 104, and the second conversion inner bevel gear 519 is transmission-connected to the scraper chain 204. A rolling bevel gear 520 is inserted into the outer shaft end of one group of rolling rollers 510, and when the cleaning frame 502 rotates to a position where the cleaning belt 503 and the top entrance of the coal slime discharge hopper 104 are directly opposite, the rolling bevel gear 520 just meshes with the second conversion inner bevel gear 519;

[0043] Here’s how it works:

[0044] The part below the slope of the inner cavity of the sedimentation box 101 is used to hold the coal slime water to be precipitated, and its purpose is to facilitate the scraping and separation of the precipitated coal slime;

[0045] The purpose of setting the mobile diversion component 3 is to allow the coal slurry water to be evenly deposited on the bottom surface of the inner cavity of the sedimentation box 101, and to avoid the phenomenon of uneven sedimentation of the coal slurry on the bottom surface of the inner cavity of the sedimentation box 101 due to water scouring;

[0046] When the diverter box 301 is used to inject coal slurry water into the inner cavity of the sedimentation box 101, the arc-shaped flap 402 is flipped upwards and in place. At this time, the arc-shaped flap 402 is used as the bottom surface of the diverter box 301. Since the top of the water-accumulating partition plate 307 is lower than the top of the side wall of the diverter box 301, and the water injection end is located in the middle of the diverter box 301, the coal slurry water can first enter the cavity formed by the water-accumulating partition plate 307 and the arc-shaped flap 402, and then the coal slurry water can enter the cavity formed by the water-accumulating partition plate 307 and the arc-shaped flap 402. After the cavity formed by the water-accumulating partition plate 307 and the arc-shaped flap 402 is buried, the water will overflow from the top of the water-accumulating partition plate 307, and be uniformly discharged laterally outward from the gap formed by the bottom end of the side wall of the diverter box 301 and the outer arc surface of the arc-shaped flap 402. In this process, the diverter box 301 is in a state of reciprocating movement within a certain range, so that the coal slurry water discharged from the diverter box 301 can be evenly distributed in the inner cavity of the sedimentation box 101;

[0047] In addition, since there is a certain gap between the outer arc surface of the arc flap 402 and the bottom end of the water accumulation partition plate 307, a very small portion of the coal slurry water is allowed to be discharged outward from the gap between the bottom end of the water accumulation partition plate 307 and the outer arc surface of the arc flap 402, which will not adversely affect the process of uniform distribution of the coal slurry water from the diversion box 301 to the sedimentation box 101;

[0048] The coal slurry water is precipitated in the inner cavity of the sedimentation box 101 to form coal slurry, the water in the upper layer of the sedimentation box 101 is emptied, and the driving mechanism connected to the scraping chain 204 is started to drive the scraping chain 204 to roll, so that the scraping plate 207 scrapes the bottom surface of the inner cavity of the sedimentation box 101, and the coal slurry precipitated on the bottom surface of the inner cavity of the sedimentation box 101 is scraped toward the coal slurry discharge hopper 104, and discharged from the outlet at the bottom end of the coal slurry discharge hopper 104;

[0049] During this process, the cleaning frame 502 will rotate to a position where it does not interfere with the inflow and outflow of the coal slime discharge hopper 104, and will not interfere with the downward discharge of the coal slime from the coal slime discharge hopper 104;

[0050] When the outer arc surface of the arc flap 402 is used as the bottom surface of the diverter box 301, some coal slime is deposited and attached to the outer arc surface of the side stand 401, so it is necessary to clean the outer arc surface of the arc flap 402 regularly;

[0051] By automatically flipping the arc-shaped flap 402 to face the outer arc surface downward, the scraping plate 207 connected between the scraping chains 204 on the top layer can contact the outer arc surface of the arc-shaped flap 402. The scraping action of the scraping plate 207 and the rotation action of the arc-shaped flap 402 within a certain range after the outer arc surface faces downward can scrape away the coal slime attached to the outer arc surface of the arc-shaped flap 402.

[0052] At the same time, after the scraper plate 207 has been used for a period of time, coal slime is also attached to the scraper plate 207, so the scraper plate 207 also needs to be cleaned regularly;

[0053] By rotating the cleaning frame 502 to a position where the cleaning belt 503 is directly opposite to the inlet of the coal slime discharge hopper 104, the bristles on the outside of the cleaning belt 503 with a certain elasticity will protrude into the inner cavity of the sedimentation box 101 and come into frictional contact with the scraper plate 207, and the rolling bevel gear 520 and the second conversion inner bevel gear 519 are meshed in place. As the scraper chain 204 rolls and drives the scraper plate 207 to move, the cleaning belt 503 can be synchronously driven to form a rolling state. The relative movement between the scraper plate 207 and the bristles of the cleaning belt 503 can automatically clean the coal slime attached to the scraper plate 207.

[0054] The specific structure of the box member 1 is as follows: Figure 1 , Figure 2 and Figure 3 As shown, the water inlet 102 and the water outlet 103 of the box body are connected to the upper end of the side wall of one side of the sedimentation box body 101, and the water inlet 102 and the water outlet 103 of the box body are located below the slope of the inner cavity of the sedimentation box body 101;

[0055] The inlet of the water outlet 103 of the box is connected to a corrugated hose, and the outlet is connected to a water pump connected to the next water tank. The corrugated hose is movable, and will not interfere with the reciprocating movement of the diversion box 301, nor will it interfere with the scraping action formed by the scraping chain 204 driving the scraping plate 207;

[0056] After the coal slime water in the inner cavity of the sedimentation box 101 is precipitated, it can also extend into the bottom of the inner cavity of the sedimentation box 101 to discharge the upper layer of water into the next level water tank;

[0057] The water inlet 102 of the box body can also be used to add coal slurry water into the inner cavity of the sedimentation box body 101, forming two different water inlet modes with the water inlet of the diversion box 301, which can better adapt to different operating environments.

[0058] The specific structure of the scraping assembly 2 is as follows: Figure 3 and Figure 4As shown, the outer walls of both sides of the cavity of the sedimentation box 101 are fixedly installed with bearing seats 201 in pairs, and the bearing seats 201 on the same side are rotatably connected with a transverse connecting shaft 202, and both ends of each set of transverse connecting shafts 202 are plugged and fixed with a scraper sprocket 203, and the two ends of the scraper chain 204 are respectively sleeved and installed in different scraper sprockets 203;

[0059] The sprocket wheels 205 are also provided at the corner positions on both sides of the slope of the inner cavity bottom surface of the sedimentation box 101. The sprocket wheels 205 are rotatably connected with the sprocket wheel seats 206. The sprocket wheel seats 206 are fixed to the outer side wall of the sedimentation box 101. The outer side of the sprocket wheels 205 contacts the inner arc surface of the scraping chain 204 at the corner position, so as to guide the distribution of the scraping chain 204 along the slope of the inner cavity bottom surface of the sedimentation box 101, and there is no relative interference between the sprocket wheels 205 and the scraping chain 204.

[0060] The scraping reduction motor group 208 is installed and fixed on the outer wall of the sedimentation box 101, and the outer shaft end of a group of transverse connecting shafts 202 located on the upper side is fixedly connected to the output end of the scraping reduction motor group 208, which can drive the transverse connecting shaft 202 to rotate slowly;

[0061] After the horizontal connecting shaft 202 rotates slowly, the scraper sprockets 203 fixed at both ends can form a state of synchronous rolling of the two groups of scraper chains 204.

[0062] The specific structure of the mobile diversion component 3 is as follows: Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the side linear guide rails 302 are symmetrically fixed to the outer side walls of the two ends of the sedimentation box 101, and the two outer ends of the diversion box 301 are fixedly connected with corner connecting arms 304, and the inner side of the bottom end of each set of corner connecting arms 304 is fixedly installed with a side slider 303, and the side slider 303 on the same side is slidably connected to the side linear guide rail 302;

Similarly, the diversion water inlet 306 is connected to the external coal slurry water inlet through a corrugated hose, which will not interfere with the automatic movement of the diversion box 301;

[0064] Fixed wheel seats 308 are fixedly installed on both sides of the outer wall of the sedimentation box 101, and the drive connecting shaft 310 is rotatably connected to the drive shaft seat 309. The drive shaft seat 309 is fixed to the outer wall of the sedimentation box 101 and is at the same height as the fixed wheel seat 308. Moving sprockets 311 are installed at the ends of both sides of the drive connecting shaft 310 and the outer shaft ends of the fixed wheel seat 308, and the moving sprocket 311 on one side is rotatably connected to the fixed wheel seat 308, and the moving sprocket 311 on the other side is fixedly connected to the drive connecting shaft 310, and the two ends of the moving chain 312 are respectively sleeved and installed in different moving sprockets 311;

[0065] A long chain connecting plate 313 is fixedly connected between each group of moving chains 312, and the length of the long chain connecting plate 313 is consistent with the length of the corner connecting arm 304, and the outer end of the corner connecting arm 304 on the same side is fixedly connected to the inner end of the long chain connecting plate 313. Within the moving stroke range of the diverter box 301, the long chain connecting plate 313 will not move to a position in contact with the moving sprocket 311, that is, the long chain connecting plate 313 is always located on the straight path of the moving chain 312;

[0066] The mobile reduction motor group 314 is installed and fixed on the outer wall of the sedimentation box 101, and the middle part of the driving connecting shaft 310 is fixedly connected to the output end of the mobile reduction motor group 314;

[0067] In order to realize the reciprocating movement of the diverter box 301, a travel switch can be installed on both sides of the outer wall of the sedimentation box 101, or other methods such as presetting the running time of the mobile reduction motor group 314 through PLC can be adopted to form a return movement when the diverter box 301 moves to a certain position. This is the existing technology and will not be elaborated on here.

[0068] The specific structure of the flip type arc plate assembly 4 is as follows Fig. 9 and Fig.10 As shown, both sides of the inner arc surface of the arc-shaped flap 402 are fixed with flap inner arms 403, the flip shaft 404 is transversely fixedly connected between the other ends of the two sets of flap inner arms 403, the side stand 401 is symmetrically fixedly connected to the outer lower end of the shunt box 301, and the two ends of the flip shaft 404 are rotatably connected to different side stands 401;

[0069] A small turning gear 405 is inserted and fixed to the outer end of each set of turning shafts 404, a push rotary seat 406 is fixed to one side of each set of side seats 401, a push large gear 407 is rotatably connected to each set of push rotary seats 406, and the push large gear 407 on the same side is meshed with the small turning gear 405;

[0071] The flip electric cylinder 410 is connected to an external hydraulic control system. By starting the flip electric cylinder 410, the telescopic rod of the flip electric cylinder 410 is driven to move, which can push the large gear 407 and the flip small gear 405 to form an unequal ratio transmission connection, so that the flip electric cylinder 410 can drive the flip plate inner arm 403 and the arc-shaped flip plate 402 to flip at a larger angle within a smaller stroke range.

[0072] Furthermore, the coordinated transmission formed by the flipping electric cylinder 410 , the pushing large gear 407 and the flipping small gear 405 will not affect the movement of the diversion box 301 in the inner cavity of the sedimentation box 101 .

[0073] The specific structure of the scraper cleaning assembly 5 is as follows Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.15 As shown, the inner rotating seat 501 is fixedly connected to one side of the inner top surface of the coal slime discharge hopper 104, and the cleaning frame 502 is rotatably connected to the inner rotating seat 501 through a connecting inner shaft 504 fixed at the other end;
