In particular, the high-solid-content slurry is a slurry having a solid concentration of up to 30% or more, and for convenience of explanation, a nickel ore slurry will be described as an example:

It can be appreciated that, because the feeding end of the high-pressure-taking pipe 230 is connected to the bottom end of the high-solid tank 300, the discharging end of the high-pressure-taking pipe 230 is led to the high-pressure-sensing portion 2220 of the liquid level transmitter 220, when the nickel ore slurry is injected into the high-solid tank 300, the nickel ore slurry can be pressed against the high-pressure-sensing portion 2220 of the liquid level transmitter 220 by the high-pressure-taking pipe 230, the purge ring 120 is hermetically arranged between the high-pressure-sensing portion 2220 of the liquid level transmitter 220 and the discharging end of the high-pressure-taking pipe 230, the sewage drain 130 is connected to the sewage tank 140 and the inner ring of the purge ring 120, and a sewage drain hole 1220 is formed on the inner ring surface of the purge ring 120, and the deposited nickel ore slurry sediment in the high-pressure-taking pipe 230 can be discharged to the sewage tank 140 through the sewage pipe 130, so as to avoid the excessive quick pollution blocking of the high-pressure-taking pipe 230.

It will be appreciated that when the nickel ore slurry is deposited in the high pressure tapping pipe 230, the flow rate of the drain pipe 130 will be reduced and even the drain hole 1220 will be blocked, so that the user can observe the discharge rate of the nickel ore slurry deposit through the drain pipe 130, and determine the deposition condition of the nickel ore slurry deposit in the high pressure tapping pipe 230. Because the air source pipe 110 is communicated with the high-pressure air source and the inner ring of the purging ring 120, and the air blowing holes 1210 are formed on the inner ring surface of the purging ring 120, the high-pressure air source can timely charge the high-pressure air into the high-pressure taking pipe 230 through the air blowing holes 1210, the high-pressure air can purge the nickel ore pulp sediment deposited in the high-pressure taking pipe 230 back into the high-solid-content tank 300, and finally, the effect of timely removing the nickel ore pulp sediment in the high-pressure taking pipe 230 is achieved, so that the interference of the nickel ore pulp sediment in the high-pressure taking pipe 230 on the high-pressure sensing part 2220 of the liquid level transmitter 220 is eliminated, and finally, the liquid level transmitter 220 is accurately displayed.

It will be appreciated that by communicating the first end of the air source tube 110 with the high pressure air source, the second end of the air source tube 110 is communicated with the inner ring of the purge ring 120, and the air blowing holes 1210 are formed on the inner ring surface of the purge ring 120, so that the nickel ore pulp precipitate can be removed in the form of blowing through the air blowing holes 1210, compared with the conventional technology, no complex pipeline for conveying the reflux liquid and no pump equipment are required to be additionally arranged, and the anti-blocking device for the liquid level detection of the high-solid-content tank 300 has simpler structure and simpler later maintenance.

In one embodiment, air or nitrogen may be used as the gas in the high pressure gas source. It will be appreciated that other high pressure gases may be used for the gas in the high pressure gas source, and that other options are possible as desired by those skilled in the art without limitation.

In one embodiment, the pressure of the high pressure gas in the high pressure gas source ranges from 0.6mpa to 0.8mpa. It will be appreciated that the specific pressure values may be 0.6mpa, 0.7mpa, 0.8mpa, and are not limited thereto, and may be adjusted by those skilled in the art according to the operating conditions.

In one embodiment, both the high pressure sensing portion 2220 of the level transmitter 220 and the low pressure sensing portion 2210 of the level transmitter 220 are provided with pressure sensing diaphragms 2212. It can be appreciated that the accuracy of the hydraulic sensing can be improved by sensing the hydraulic pressure of the nickel ore pulp through the pressure measuring membrane 2212.

As shown in connection with fig. 2-3, in one embodiment, a first seal ring 410 is disposed between the purge ring 120 and the high pressure sensing portion 2220 of the level transmitter 220. It can be appreciated that the gap between the purge ring 120 and the high pressure sensing portion 2220 of the liquid level transmitter 220 is filled by the first seal ring 410, so that the tightness between the purge ring 120 and the high pressure sensing portion 2220 of the liquid level transmitter 220 can be enhanced, and leakage of high-solid slurry or high-pressure gas can be prevented. In this embodiment, a second sealing ring 420 is further disposed between the purge ring 120 and the discharge end of the high pressure tapping pipe 230. It can be appreciated that the second sealing ring 420 fills the gap between the purge ring 120 and the discharge end of the high pressure pipe 230, so as to enhance the tightness between the purge ring 120 and the discharge end of the high pressure pipe 230 and prevent leakage of high-solid slurry or high-pressure gas. Specifically, the first sealing ring 410 and the second sealing ring 420 can both use metal winding gaskets, and the metal winding gaskets have better high temperature resistance and corrosion resistance and can adapt to more complex working conditions. Of course, the present invention is not limited thereto, and those skilled in the art can also substitute according to the working conditions.

Referring to fig. 2 to 3, in one embodiment, a clamping assembly is further fixed on the outer ring surface of the purge ring 120, and the clamping assembly includes a first elastic clamping jaw 510 and a second elastic clamping jaw 520 that are oppositely disposed; the first elastic clamping jaw 510 and the second elastic clamping jaw 520 are used for clamping the high pressure sensing part 2220 of the liquid level transmitter 220 together. It can be appreciated that, because the first elastic clamping jaw 510 and the second elastic clamping jaw 520 are disposed opposite to each other, the first elastic clamping jaw 510 and the second elastic clamping jaw 520 can simultaneously press against the high pressure sensing portion 2220 of the clamping level transmitter 220, so as to prevent the purge ring 120 from generating lateral force when the purge ring 120 blows through the blowing hole 1210, thereby causing the purge ring 120 to shift.

In one embodiment, the clamping ends of the first elastic clamping jaw 510 and the second elastic clamping jaw 520 are respectively provided with a pressing piece 530, and the pressing piece 530 is adapted to and pressed against the periphery of the high pressure sensing portion 2220 of the level transmitter 220. It can be appreciated that, by disposing the pressing piece 530 at the clamping end of the first elastic clamping jaw 510 and the clamping end of the second elastic clamping jaw 520, the pressing piece 530 is adapted to the periphery of the high pressure sensing portion 2220 of the liquid level transmitter 220, so that the clamping area can be increased, and the first elastic clamping jaw 510 and the second elastic clamping jaw 520 can be clamped more stably and firmly.

In one embodiment, as shown in FIG. 4, a drain 1220 is provided near the bottom end of the inner annulus. It will be appreciated that, the drain hole 1220 is disposed near the bottom end of the inner annulus, because the nickel ore pulp is deposited downwards, the flow change of the drain pipe 130 or the blockage of the drain hole 1220 can be more easily caused by the nickel ore pulp deposition, so that the flow change of the drain pipe 130 can more sensitively reflect the deposition of the nickel ore pulp deposition, and the user can purge the nickel ore pulp in time through the purging component according to the flow change of the drain pipe 130.

In one embodiment, as shown in FIG. 4, a gas vent 1210 is provided near the top of the inner annulus. It will be appreciated that by arranging the gas vent 1210 at a top end near the inner annulus, the gas vent 1210 can be prevented from being blocked by the nickel ore pulp deposit because the nickel ore pulp is deposited downwards, thereby enabling the gas vent 1210 to better purge the nickel ore pulp deposit and achieve better unblocking effect.

In one embodiment, the blowhole 1210 is positioned opposite the blow-down hole 1220. It can be appreciated that by arranging the positions of the blowhole 1210 and the blowhole 1220 to be opposite, the high-pressure gas blown by the blowhole 1210 during the blowing process can directly flush the nickel ore pulp deposit deposited on the surface of the blowhole 1220, so as to more rapidly and cleanly blow off the nickel ore pulp deposit around the blowhole 1220, ensure that the blowhole 1220 remains clear during the reuse, and sensitively reflect the nickel ore pulp deposit deposition condition.

Referring to fig. 3 and fig. 4, in one embodiment, the discharge end of the high pressure gauge pipe 230 is further connected to a first flange 2310, a second flange 2211 is further formed on the periphery of the high pressure sensing portion 2220 of the liquid level transmitter 220, the first flange 2310 and the second flange 2211 are locked by a locking assembly, and the purge ring 120 is pressed between the first flange 2310 and the second flange 2211. It can be appreciated that, because the first flange and the second flange are connected by the locking assembly, the purge ring 120 is pressed between the first flange 2310 and the second flange 2211, so that the purge ring 120 can form a tighter connection structure with the first flange 2310 and the second flange 2211, and thus high-pressure gas and nickel ore pulp are not easy to leak. At the same time, the purge ring 120 can also be better constrained between the first flange 2310 and the second flange 2211, so that the purge ring 120 can better overcome the lateral forces during purging. In this embodiment, the locking assembly includes a bolt 2312 and a nut 2313, corresponding mounting holes 2311 are formed in the first flange 2310 and the second flange 2211, the bolt 2312 penetrates through the mounting holes 2311 opposite to the first flange 2310 and the second flange 2211, and is screwed to the nut 2313, so that the first flange 2310 and the second flange 2211 are locked, and connection tightness between the first flange 2310 and the second flange 2211 is further improved.

In one embodiment, as shown in fig. 4, the diameter of the inner cavity 2314 of the first flange 2310 gradually decreases from a discharge end far from the high-pressure tapping pipe 230 to a discharge end near to the high-pressure tapping pipe 230. It will be appreciated that, because the diameter of the inner cavity 2314 of the first flange 2310 is gradually reduced from the discharge end far from the high-pressure tapping pipe 230 to the discharge end close to the high-pressure tapping pipe 230, the longitudinal section of the inner cavity 2314 of the first flange 2310 is funnel-shaped, and because the smaller diameter end of the inner cavity 2314 of the first flange 2310 is connected to the discharge end of the high-pressure tapping pipe 230, when the high-pressure gas is blown out by the gas blowing holes 1210 of the blowing ring 120, the high-pressure gas can form a larger blowing force at the connection position between the first flange 2310 and the discharge end of the high-pressure tapping pipe 230, so that the high-pressure gas can better purge the nickel ore slurry in the high-pressure tapping pipe 230 into the high-solid-content tank 300, and finally, the blowing process is faster.

In one embodiment, as shown in FIG. 1, a solenoid valve 600 is provided on air supply tube 110. It can be appreciated that the solenoid valve 600 is used for electrically connecting to an external DCS (distributed control) system, and the DCS system controls the opening and closing of the solenoid valve 600 on the air source pipe 110 at regular time, so that the high-pressure air in the high-pressure air source can enter the high-pressure taking pipe 230 through the air blowing port of the blowing ring 120, the nickel ore pulp sediment in the high-pressure taking pipe 230 is blown, and the regular and automatic blowing can effectively prevent the high-pressure taking pipe 230 from being excessively blocked, and meanwhile, the labor cost is reduced. Specifically, the purge interval may be set by summarizing the discharge rate variation or the plugging frequency of the nickel ore slurry in the blow down pipe 130.

It should be noted that, the method for controlling the electromagnetic valve 600 to be opened and closed by the DCS system described above belongs to the prior art, and is not in the scope of the present disclosure, and the present disclosure only protects the components of the high-solid-content tank liquid detection anti-blocking device 10 and the connection relationship thereof. It will be appreciated that the person skilled in the art is not limited to using this method, but may be implemented using other methods.

In one embodiment, the pressure of the high pressure gas source is higher than the pressure within the high solids tank 300. It can be appreciated that, because the pressure in the high-pressure gas source is higher than the pressure in the high-solid content tank 300, when the high-pressure gas source is sequentially connected to the high-solid content tank 300 through the gas source pipe 110, the purge ring 120 and the high-pressure sampling pipe 230, the high-pressure gas in the high-pressure gas source can smoothly purge the nickel ore slurry in the high-pressure sampling pipe 230 into the high-solid content tank 300.

In one embodiment, as shown in connection with fig. 1, the high solids tank body fluid detection anti-clogging device 10 further includes a dirt guide tube 700, the dirt guide tube 700 being in communication with the bottom of the high solids tank body 300. It will be appreciated that after the nickel ore slurry precipitate in the high pressure tap 230 is purged into the high solids tank 300 through the high pressure tap 230, the nickel ore slurry precipitate will be gravity settled to the bottom of the high solids tank 300 and discharged out of the high solids tank 300 by opening the dirt duct 700. In this embodiment, the dirt guiding pipe 700 is connected to the dirt collecting tank 800, and the discharged nickel ore pulp precipitate is collected by the dirt collecting tank 800 to facilitate centralized treatment, so that the pollution of the external environment due to the dirt discharged outside of the nickel ore pulp precipitate is avoided. In this embodiment, the opening and closing are achieved by providing a ball valve 710 on the dirt guide 700.

In one embodiment, for a better understanding, the liquid level detection and de-plugging process of the high solids tank liquid level detection anti-plugging device 10 is described below:

When the device is used, because the feeding end of the low-pressure taking pipe 210 is communicated with the top end of the high-solid-content tank 300, the low-pressure taking pipe 210 is higher than the liquid level of the high-solid-content slurry in the high-solid-content tank 300, and because the discharging end of the low-pressure taking pipe 210 is led to the low-pressure sensing part 2210 of the liquid level transmitter 220, the air above the high-solid-content slurry level in the high-solid-content tank 300 can act on the low-pressure sensing part 2210 of the liquid level transmitter 220 through the low-pressure taking pipe 210, and meanwhile, because the feeding end of the high-pressure taking pipe 230 is communicated with the bottom end of the high-solid-content tank 300, the high-pressure taking pipe 230 is lower than the liquid level of the high-solid-content slurry in the high-solid-content tank 300, and because the discharging end of the high-pressure taking pipe 230 is led to the high-pressure sensing part 2220 of the liquid level transmitter 220, the high-solid-content slurry at the bottom of the high-solid-content tank 300 can act on the high-pressure sensing part 2210 of the liquid level transmitter 220, and the high-solid-content slurry level sensor 220 can feel the high-solid-content slurry level value after the liquid level sensor 220 is processed at the high-solid-content tank 300. And part of the nickel ore pulp sediment flows into the sewage draining pool 140 through the sewage draining pipe 130, when a user observes that the discharging rate of the nickel ore pulp in the sewage draining pipe 130 changes or is blocked, the high-pressure air source is communicated through the air source pipe 110 to timely purge the high-pressure taking pipe 230. The nickel ore pulp sediment in the high-pressure taking pipe 230 is purged into the high-solid-content tank 300 and is settled to the bottom of the high-solid-content tank 300, and finally is led out to the sewage collecting tank 800 through the sewage guide pipe 700 at the bottom of the high-solid-content tank 300.

Compared with the prior art, the method has at least the following advantages:

1) Because the feeding end of the high-pressure-taking pipe 230 is communicated with the bottom end part of the high-solid-content tank body 300, the discharging end of the high-pressure-taking pipe 230 is led to the high-pressure-sensing part 2220 of the liquid level transmitter 220, when the nickel ore pulp is injected into the high-solid-content tank body 300, the nickel ore pulp can be propped against the high-pressure-sensing part 2220 of the liquid level transmitter 220 through the high-pressure-taking pipe 230, the purging ring 120 is arranged between the high-pressure-sensing part 2220 of the liquid level transmitter 220 and the discharging end of the high-pressure-taking pipe 230 in a sealing manner, the sewage drain pipe 130 is communicated with the sewage pool 140 and the inner ring of the purging ring 120, and a sewage drain hole 1220 is formed on the inner ring surface of the purging ring 120, and the deposited nickel ore pulp precipitation part in the high-pressure-taking pipe 230 can be discharged to the sewage pool 140 through the sewage pipe 130, so that the high-pressure-taking pipe 230 is prevented from being blocked too fast.

2) When the nickel ore pulp is deposited in the high-pressure sampling pipe 230, the flow rate of the drain pipe 130 is reduced and even the drain hole 1220 is blocked, so that a user can observe the discharge rate of the nickel ore pulp deposit through the drain pipe 130, and determine the deposition condition of the nickel ore pulp deposit in the high-pressure sampling pipe 230. Because the air source pipe 110 is communicated with the high-pressure air source and the inner ring of the purging ring 120, and the air blowing holes 1210 are formed on the inner ring surface of the purging ring 120, the high-pressure air source can timely charge the high-pressure air into the high-pressure taking pipe 230 through the air blowing holes 1210, the high-pressure air can purge the nickel ore pulp sediment deposited in the high-pressure taking pipe 230 back into the high-solid-content tank 300, and finally, the effect of timely removing the nickel ore pulp sediment in the high-pressure taking pipe 230 is achieved, so that the interference of the nickel ore pulp sediment in the high-pressure taking pipe 230 on the high-pressure sensing part 2220 of the liquid level transmitter 220 is eliminated, and finally, the liquid level transmitter 220 is accurately displayed.

3) Through with the first end intercommunication high-pressure air supply of air supply pipe 110, the second end intercommunication of air supply pipe 110 is to the inner ring of sweeping ring 120 to form gas blowing hole 1210 on the inner ring face of sweeping ring 120, make can adopt the form of blowing through gas blowing hole 1210 to get rid of nickel ore pulp deposit, compare with the conventional art and need not additionally set up the complicated pipeline of carrying the reflux liquid and send pump equipment outward, foretell high solid contains jar body 300 liquid level detection anti-clogging device structure is simpler, and later maintenance is simpler.
