DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Embodiment: The ore slurry is mainly a mixture of ore particles, liquid water, etc., and the filtration process is mainly to separate the ore and water to obtain ore solid matter; However, there are more ore solids in the slurry. During continuous filtration, the filter will quickly fill up, affecting the permeability of the filter and reducing the filtration speed. At the same time, for some low-concentration slurry filtration, the filtration speed is slower than that of water, which also affects the filtration speed to a certain extent. To do this, please refer to Figure 1 to Figure 14 As shown, the present invention provides a temporary filtration device for gold mines, comprising a filter cartridge 001, a feed pipeline 002 connected to the top of the filter cartridge 001, and a discharge pipeline 003 connected to the bottom of the filter cartridge 001; the feed pipeline 002 is mainly used to introduce the ore slurry into the filter cartridge 001, and the discharge pipeline 003 is mainly used to discharge the filtered slurry liquid; The present invention also includes a support beam 100, a counterweight plate 101, a filter cloth 102 and a counterweight ball 103; the support beam 100 is fixedly installed on the inner bottom of the filter cartridge 001; the counterweight plate 101 is arranged in an annular shape, and the side surface is in contact with the inner wall of the filter cartridge 001, and the counterweight plate 101 is placed on the support beam 100 by gravity; the filter cloth 102 is connected end to end to form a conical component with a wide upper mouth and a narrow lower mouth; wherein the wide upper mouth of the filter cloth 102 passes through the counterweight plate 101 and is fixed to the top surface of the counterweight plate 101 by bolts or can be The detachable connection, the lower narrow opening can be sealed by a cable tie; the weight ball 103 is installed at the lower narrow opening of the filter cloth 102, and the filter cloth 102 always maintains a conical shape under the gravity of the weight ball 103, and the surface is tight; wherein, the weight ball 103 can be lifted back and forth in the vertical direction to make the filter cloth 102 vibrate, and generally a cam that contacts the weight ball 103 can be set below the weight ball 103, and the cam is equipped with an external motor for use, and the rotation of the cam continuously pushes the weight ball 103 to jump in the vertical direction, etc., without limitation; When the above scheme is used: the ore slurry is continuously introduced into the filter cartridge 001 from the feed pipeline 002, and flows through the filter cloth 102 from top to bottom to form filtration, and the filtered liquid is discharged from the discharge pipeline 003; In the above filtering process, since the filter cloth 102 is in a cone shape as a whole, a three-dimensional filtering space is constructed and a three-dimensional filtering effect is formed, which has better effect and efficiency than the plane filtering method; at the same time, after filtering by the filter cloth 102, the solid matter (mainly ore particles) filtered out of the slurry will flow to the lower part of the filter cloth 102 by gravity, and will be orderly retained at the inner bottom of the filter cloth 102 by gravity, while the rest of the filter cloth 102 (mainly the upper part) will not be blocked by the solid matter, so that the upper part of the filter cloth 102 is always transparent, ensuring that the slurry filtering can be carried out continuously; In addition, the weighted ball 103 can be lifted back and forth in the vertical direction to make the filter cloth 102 vibrate, thereby accelerating the solid matter attached to the inner surface of the filter cloth 102 to quickly gather and collect to a lower place, and can also accelerate the low-concentration slurry to pass through the filter cloth 102, thereby improving the filtering effect and efficiency.

[0019] Furthermore, a top beam 200 is installed on the inner top of the filter cartridge 001; a steering wheel 201 is rotatably installed on the top beam 200; a rope 202 is also arranged in the axial direction of the filter cartridge 001, one end of which extends into the filter cloth 102 and is fixedly connected to the weight ball 103, and the other end passes through the steering wheel 201 and extends horizontally to the outside of the filter cartridge 001 to form a winding connection with the winding roller on the output shaft of the winding motor 203; wherein the steering wheel 201 divides the rope 202 into a horizontal section and a vertical section; When the above scheme is in use: when installing and using filter cloths 102 of different lengths, the height of the counterweight ball 103 changes, so the length of the vertical section rope 202 needs to be adjusted to ensure that it is tight; for this purpose, the winding motor 203 can be activated and the rope 202 and the counterweight ball 103 can be reeled in to different positions to ensure that the vertical section rope 202 is tight, and the counterweight ball 103 can ensure that the filter cloth 102 is always in a relatively tight state under the action of gravity, so that it is suitable for the application of filter cloths 102 of different sizes.

[0020] In order to discharge the solid matter in the filter cloth 102, a discharge port 300 is provided through the side of the filter cartridge 001. There are multiple discharge ports 300, and the discharge ports 300 are located above the counterweight plate 101. When the above scheme is in use: the external winding motor 203 can be activated, and the winding roller of its output shaft can lift the counterweight ball 103 upward at a uniform speed by winding the rope 202. When the counterweight ball 103 moves above the filter cloth 102, the upward movement of the counterweight ball 103 will pull the filter cloth 102 upward as a whole. At this time, the filter cloth 102 will be turned over, and when the filter cloth 102 is tightened as a whole, the filter cloth 102 will form an angle for solid matter to tilt and pour after turning over, and the solid matter will move to a lower place. (Move to the inner wall of the filter cartridge 001), and temporarily stored between the filter cloth 102 and the inner wall of the filter cartridge 001 after turning over. At this time, as the weight ball 103 drives the filter cloth 102 to continue to rise, the filter cloth 102 will pull the weight plate 101 that is in contact with the inner wall of the filter cartridge 001 to slide upward. Similarly, the solid matter will also move upward with the filter cloth 102 and the weight plate 101. When it is flush with the discharge port 300, the solid matter in the filter cloth 102 will form an opportunity to dump and be discharged from the discharge port 300. On the contrary, after the solid matter in the filter cloth 102 is discharged, the winding motor 203 can be controlled to move in the reverse direction, at which time the rope 202 and the weight ball 103 continuously move downward, thereby driving the filter cloth 102 to return to the initial filtering state.

[0021] Furthermore, a baffle plate 301 for blocking the discharge port 300 is installed on the top of the counterweight plate 101 through a plurality of support rods; the outer side surface of the baffle plate 301 is slidably fitted with the inner wall of the filter cartridge 001; When the above scheme is in use: under the action of gravity of the counterweight ball 103, the filter cloth 102 is in a taut state as a whole, and the counterweight plate 101 is placed on the support beam 100 at this time, and the baffle 1 301 blocks the discharge port 300 at this time, ensuring that in the non-discharging state, the slurry will not flow out of the discharge port 300 during the falling process from top to bottom; and on the basis of the rope 202 lifting and driving the filter cloth 102 and the counterweight plate 101 to move upward, the counterweight plate 101 can also drive the baffle 1 301 to move upward synchronously, so that during the continuous upward movement, the baffle 1 301 will gradually lose its blockage of the discharge port 300, thereby ensuring that the solid matter in the filter cloth 102 enters the unloading state.

[0022] Furthermore, a baffle plate 302 is installed inside the filter cartridge 001 and is located above the discharge port 300; the outer side surface of the baffle plate 302 is in contact with the inner wall of the filter cartridge 001, and the inner side surface and the portion of the baffle plate 302 extending toward the center are made of rubber material; When the above scheme is in use: on the basis of the lifting of the rope 202 driving the filter cloth 102 and the counterweight plate 101 to move upward, when the filter cloth 102 is lifted to the maximum stroke, the surface of the filter cloth 102 will extend into the baffle plate 2 302 and fit with the inner surface of the baffle plate 2 302. At this time, the slurry input from the feed pipeline 002 will fall into the area between the baffle plate 2 302 and the filter cloth 102 for filtration, which to a certain extent reduces the possibility of the slurry flowing directly to the discharge port 300 along the inclined surface of the filter cloth 102, and reduces the situation of continuous injection of slurry loss when the solid matter is unloaded. At this time, the baffle plate 1 301 just loses the blockage of the discharge port 300, and the solid matter between the baffle plate 2 302, the baffle plate 1 301, the filter cloth 102 and the inner wall of the filter cylinder 001 is discharged normally; That is, the above scheme can filter the slurry continuously injected into the feed pipeline 002 without affecting the discharge of solid matter from the discharge port 300 through the coordination of baffle 1 301 and baffle 2 302, without stopping the slurry injection during the solid matter discharge process, thereby realizing sustainable filtration operation.

[0023] In order to realize that the weight ball 103 can be lifted reciprocatingly in the vertical direction, so as to form vibration of the filter cloth 102; for this purpose, the present application also includes a driving mechanism 400 for lifting the weight ball 103 reciprocatingly in the vertical direction; the driving mechanism 400 includes an electric push rod 401, a slide rod 402, a protrusion 403, a lifting plate 404 and a contact plate 405; the electric push rod 401 is installed on the top outer side of the filter cartridge 001, and its output shaft extends into the interior of the filter cartridge 001; the slide rod 40 2 is located in the filter cartridge 001 and is arranged horizontally as a whole, and one end of the slide rod 402 is fixedly connected to the output shaft of the electric push rod 401; a plurality of protrusions 403 are arranged on the top of the slide rod 402; a lifting plate 404 is provided on the top beam 200 for vertical limited sliding; the top of the lifting plate 404 is in contact with the rope 202 of the horizontal section; a contact plate 405 is provided at the bottom of the lifting plate 404, and the contact plate 405 is located on the moving path of the protrusion 403, and the two form an extrusion fit; When the above scheme is in use: the electric push rod 401 is moved, and its output shaft can be reciprocated and extended, thereby driving the slide bar 402 to form a lateral reciprocating movement. During the process, the multiple protrusions 403 on the top of the slide bar 402 will continuously squeeze the contact plate 405, so that the contact plate 405 and the lifting plate 404 both move up. When the protrusions 403 are not in contact with the contact plate 405, the lifting plate 404 and the contact plate 405 move down by gravity, that is, the multiple protrusions 403 move back and forth with the slide bar 402, so that the lifting plate 404 can form a reciprocating movement in the vertical direction; The reciprocating movement of the lifting plate 404 can intermittently lift the rope 202 of the horizontal section. When the lifting plate 404 lifts the rope 202, the movement of the rope 202 can also synchronously move the counterweight ball 103 upward. When the lifting plate 404 loses the lifting force on the horizontal section rope 202, the counterweight ball 103 falls rapidly under the action of gravity, thereby forming an oscillation on the surface of the filter cloth 102. Through this oscillation force, on the one hand, the filtering speed of the slurry with a certain viscosity in the filter cloth 102 can be accelerated; on the other hand, the solid matter and viscous matter attached to the inner surface of the filter cloth 102 can be accelerated to gather rapidly to the lower part, thereby improving the solid matter gathering effect and ensuring that the rest of the surface of the filter cloth 102 is transparent, thereby improving the slurry filtering speed and effect. By repeating the above operation, the weight ball 103 can be lifted back and forth along the plumb bob direction and the filter cloth 102 can be vibrated.

[0024] In order to increase the speed of the weight ball 103 moving downward and improve its shock effect on the filter cloth 102, the contact plate 405 and the lifting plate 404 are rotatably connected through a torsion spring shaft; the bottom end of the lifting plate 404 is also fixedly connected to a limit plate 406, and the limit plate 406 is in contact with the surface of one side of the contact plate 405 adjacent to the vertical section rope 202; each protrusion 403 is formed with an inclined surface on one side facing the vertical section rope 202, and a vertical surface perpendicular to the slide rod 402 is formed on the other side; When the above scheme is used: on the basis of the sliding rod 402 driving the protrusion 403 to move back and forth horizontally, when the protrusion 403 moves toward the vertical section rope 202, the inclined surface of the protrusion 403 can contact the contact plate 405, and the limiting plate 406 restricts one side of the contact plate 405, so that the contact plate 405 cannot rotate, and during the contact between the contact plate 405 and the protrusion 403, the contact plate 405 and the lifting plate 404 are pushed upward by the intervention of the protrusion 403; When the contact plate 405 passes through a protrusion 403, the other side of the protrusion 403 is a vertical surface, so that when the contact plate 405 is separated from the protrusion 403, it can fall quickly due to the weight of the contact plate 405 and the lifting plate 404. Similarly, at this time, the weight ball 103 can pull the filter cloth 102 and the rope 202 to fall quickly under the action of gravity, thereby enhancing the falling vibration effect of the weight ball 103 on the filter cloth 102. On the contrary, when the slide bar 402 drives the protrusion 403 away from the direction of the vertical section rope 202, the contact plate 405 can be adaptively flipped when contacting the protrusion 403, thereby ensuring that the electric push rod 401 can drive the slide bar 402 to move back and forth normally; It should be added that, on the basis of the winding motor 203 winding up the counterweight ball 103 and turning over the filter cloth 102 for unloading, the counterweight ball 103 is on the top and the counterweight plate 101 is on the bottom, and the filter cloth 102 between the two is always taut; the difference is that at this time, the electric push rod 401 also drives the sliding rod 402 and the protrusion 403 thereon to move, so that the lifting plate 404 also reciprocates to lift the horizontal section rope 202, and the reciprocating changes of the horizontal section rope 202 can also be transmitted to the vertical section rope 202, so that The vertical section of the rope 202 drives the filter cloth 102 to form uninterrupted shaking in the vertical direction, thereby accelerating the movement of solid matter on the surface of the filter cloth 102 to a lower place and increasing its discharge speed from the discharge port 300; it is worth noting that when the filter cloth 102 is about to fit the inner surface of the baffle 2 302, the electric push rod 401 can be suspended by the controller or manual operation to prevent the filter cloth 102 from moving up excessively and forcibly scratching and damaging the baffle 2 302. The relevant control technology is a well-known technology and will not be repeated here.

[0025] Further, the vertical section of the rope 202 is located on the moving path of the slide bar 402; When the above scheme is in use: when the electric push rod 401 drives the slide rod 402 to move in the direction of the vertical section rope 202, the end of the slide rod 402 away from the electric push rod 401 will contact and push the vertical section rope 202, so that the vertical section rope 202 deviates from the axis of the filter cartridge 001 (the counterweight ball 103 is also offset to the left at this time), and when the electric push rod 401 drives the slide rod 402 to move back to the right, the vertical section rope 202 loses the restraint of the slide rod 402, and the counterweight ball 103 will drive the vertical section rope 202 to reset under the action of gravity (ensuring that the vertical section rope 202 and the axis of the filter cartridge 001 overlap relatively), and the counterweight ball 103 will swing left and right during the reset process; similarly, the counterweight ball 103 will also drive the filter cloth 102 to shake in the left and right directions, thereby accelerating the filtering speed of the slurry in the filter cloth 102; That is, by setting the driving mechanism 400, not only can the counterweight ball 103 be moved back and forth in the plumb direction (vertical direction), but also the counterweight ball 103 can be swung in the left and right directions, thereby realizing multi-dimensional movement; and the filter cloth 102 is affected by the movement of the counterweight ball 103, and can not only realize the vibration in the vertical direction, but also form a swing in the left and right directions, thereby accelerating the filtration speed of the slurry with a certain viscosity in the filter cloth 102; at the same time, it also accelerates the rapid aggregation of solid matter and viscous matter attached to the inner surface of the filter cloth 102 to a lower place, and while improving the aggregation effect of solid matter, it also ensures that the rest of the surface of the filter cloth 102 is not blocked by the viscous matter and remains transparent, thereby further improving the filtration speed and effect of the slurry.

[0026] Furthermore, the driving mechanism 400 further includes a circular tube 407, a sealing plate 408 and a blast tube 409; the circular tube 407 is arranged horizontally and installed below the top beam 200; a sealing plate 408 is also installed in the circular tube 407, and the side of the sealing plate 408 is slidably fitted with the inner wall of the circular tube 407; the sliding rod 402 passes through the circular tube 407 as a whole and is fixedly connected to the sealing plate 408, and the contact part between the sliding rod 402 and the circular tube 407 is sealed and slidably connected; a set of one-way inlet and outlet valve pipes are provided at both ends of the circular tube 407; the supporting beam 1 The bottom end of the filter cartridge 001 is also provided with a blast pipe 409 in line with the path formed therewith, and the blast pipe 409 is located on the outside of the filter cloth 102 as a whole; the blast pipe 409 is also provided with a plurality of blast ports facing the surface of the filter cloth 102, for outputting back-blowing gas toward the surface of the filter cloth 102; wherein, the two one-way air inlet valve pipes are both connected to the outside of the filter cartridge 001, and the two one-way air outlet valve pipes are both connected to the blast pipe 409, and the pipeline connection of the one-way air inlet valve pipe and the one-way air outlet valve pipe is not shown in the figure, which is a known technology and will not be described in detail; When the above scheme is in use: on the basis of the electric push rod 401 driving the slide rod 402 to move back and forth horizontally, the slide rod 402 can drive the sealing plate 408 to move back and forth in the circular tube 407, so that the external gas of the filter cartridge 001 is continuously drawn into the circular tube 407 through the one-way air inlet valve pipe, and the gas in the circular tube 407 is continuously input into the blast pipe 409 through the one-way air outlet valve pipe, and the blown air of the blast pipe 409 forms the back-blowing gas to the surface of the filter cloth 102; The difference is that the sealing plate 408 divides the circular tube 407 into two sealed chambers, and the reciprocating movement of the sealing plate 408 enables the two sealed chambers to work at the same time (one chamber draws in gas to be squeezed out by the sealing plate 408 later, and the other chamber squeezes out the previously drawn gas through the sealing plate 408), so that the external gas of the filter cartridge 001 is continuously drawn into the circular tube 407 through the one-way air inlet valve pipe, and the gas is continuously output from the one-way air outlet valve pipe of the circular tube 407 to the blast pipe 409 through the squeezing of the sealing plate 408. In other words, the reciprocating movement of the sealing plate 408 in the circular tube 407 and the coordination of the work of the two sealed chambers can ensure that the blast pipe 409 continuously blows out gas; The above scheme aims to form continuous blowing through the blower pipe 409 and make the air flow continuously blow toward the surface of the filter cloth 102, so as to form backblowing on the water film or sticky impurities in the holes of the filter cloth 102, so as to form backblowing and clearing of the filter cloth 102, ensure the transparency of the filter cloth 102, and improve the effect of continuous filtration of the slurry in the filter cloth 102.
