[0046] The working principle and beneficial effects of the above technical solution are: the mud to be treated is added into the device, the mud is placed into the blocking assembly 8, and then the driving assembly 6 is started, at this time the driving assembly 6 drives the centrifugal cylinder 4 to rotate, and the solid-liquid substances in the mud inside the centrifugal cylinder 4 can be centrifugally separated by rotation.
[0047] In one embodiment: the driving assembly 6 includes a support rod 61, one end of the support rod 61 is fixedly installed on the base 1, the end of the support rod 61 away from the base 1 is fixedly installed with a mounting plate 62, the mounting plate 62 is fixedly installed with a driving motor 63, the lower end of the driving motor 63 is fixedly installed with a gear 64, the centrifugal cylinder 4 is fixedly installed with a gear ring 65, the gear 64 and the gear ring 65 are meshed with each other, the bottom of the centrifugal cylinder 4 is provided with a circular groove, and the side of the centrifugal cylinder 4 is provided with a discharge groove 401.
[0048] The working principle and beneficial effects of the above technical solution are: the driving motor 63 on the driving assembly 6 is started, the driving motor 63 drives the gear 64 to rotate, when the gear 64 rotates, the gear ring 65 meshed with the gear 64 moves, the sieve barrel 82 of the blocking assembly 8 separates the solid and liquid, the liquid is inside the sieve barrel 82, and the solid is outside the sieve barrel 82, and the circular groove and the discharge groove 401 are provided with opening devices, which can be selected as pneumatic valves and electric valves, when cleaning is needed, the valves are opened, the separated solid-liquid substances can be outputted, and subsequent treatment can be performed.
[0049] In one embodiment: the base 1 is fixedly installed with a control assembly 7, the control assembly 7 includes a stand 71, one end of the stand 71 is fixedly installed on the base 1, the other end of the stand 71 is fixedly installed with a special-shaped rod 72, the end of the special-shaped rod 72 away from the stand 71 is fixedly installed with a winding device 73, the winding device 73 is sleeved with a lifting rope 74, and the end of the lifting rope 74 away from the winding device 73 is fixedly connected with the blocking assembly 8.
[0050] The working principle and beneficial effects of the above technical solution are: when the centrifugal cylinder 4 needs to be cleaned, the control assembly 7 is started, the special-shaped rod 72 on the stand 71 is provided with the winding device 73, the winding device 73 is located at the center of the centrifugal cylinder 4, the winding device 73 is started to rotate, the lifting rope 74 wound thereon is shortened, and the blocking assembly 8 is lifted to separate the blocking assembly 8 from the centrifugal cylinder 4, and the centrifugal cylinder 4 and the blocking assembly 8 can be cleaned separately.
[0051] In one embodiment: the blocking assembly 8 includes a cover plate 81, the cover plate 81 is fixedly installed with a sieve barrel 82, and the edge of the sieve barrel 82 is fixedly installed with a blocking block 83.
[0052] The working principle and beneficial effects of the above technical solution are that: the mud is injected into the inside of the sieve bucket 82, since the sieve bucket 82 is hung in the centrifugal cylinder 4 by the control assembly 7, when the centrifugal cylinder 4 rotates, the sieve bucket 82 will not move, but the mud in the inside of the sieve bucket 82 will move under the action of centrifugal force, at this time, the solid material with large density will be thrown to the outside, and the liquid material with small density will be located on the inside, under the action of the blocking block 83, the solid material will be easily thrown into the space between the sieve bucket 82 and the centrifugal cylinder 4, and then reach the bottom under the action of gravity, that is, the discharging can be performed, and when the liquid in the space between the sieve bucket 82 and the centrifugal cylinder 4 is more, the blocking block 83 can reduce the probability of the solid material entering the sieve bucket 82 again.
[0053] In one embodiment: the cross section of the blocking block 83 is triangular, and the long side of the blocking block 83 is located on the side close to the sieve bucket 82, and the short side of the blocking block 83 is located on the side away from the sieve bucket 82.
[0054] The working principle and beneficial effects of the above technical solution are that: since the cross section of the blocking block 83 is triangular, and the arc on the inside of the sieve bucket 82 is small, and the arc on the outside of the sieve bucket 82 is large, when the solid material contacts the position with small arc, it will be more easily slide out from this position, and when the external solid material contacts the position with large arc, it will be more easily blocked by the blocking block 83 with large arc, reducing the probability of returning to the sieve bucket 82.
[0055] In one embodiment: the cover plate 81 is fixedly installed with a fixed plate 84, and the fixed plate 84 is fixedly installed with a protective plate 85.
[0056] The working principle and beneficial effects of the above technical solution are that: since the processing work is continuous, and the processing operation is not only the simple separation operation, part of the staff cannot always focus on the separation work, at this time, when the centrifugal cylinder 4 is full, and the centrifugal processing is performed, part of the solid material with low density which is not discharged in time will float on the liquid surface between the centrifugal cylinder 4 and the sieve bucket 82, at this time, under the action of centrifugal force, such material can be thrown out from the centrifugal cylinder 4, and then fall on the gear ring 65, through the special-shaped protective plate 85, the hard solid material can be prevented from directly impacting the gear ring 65 to cause damage, and meanwhile, the solid material in fluid state can be prevented from accumulating on the gear ring 65 to cause the rotation failure of the gear ring 65.
[0057] In one embodiment: the cover plate 81 is provided with an input assembly 9, the input assembly 9 includes a feeding pipe 91, the feeding pipe 91 is fixedly installed on the cover plate 81, the cover plate 81 is internally provided with a cavity, the feeding pipe 91 is communicated with the cavity, the inner wall of the sieve bucket 82 is fixedly installed with a fixed block 92, the fixed block 92 is provided with a plurality of discharging pipes 93, and the discharging pipes 93 are communicated with the cavity.
[0058] The working principle and beneficial effects of the above technical solution are that the feeding pipe 91 on the input assembly 9 is connected with the external pipeline, the external fluid material enters the cavity of the cover plate 81 through the feeding pipe 91, then enters the fixed block 92, and finally is input into the sieve drum 82 through the discharging pipe 93. The external can select the external material according to the needs. When there are more pyrite and sulfide particles in the slurry, Fe(OH)3 colloid is easily generated by oxidation, the viscosity of the slurry is increased, and the solid-liquid is difficult to separate. At this time, the separating agent or reducing agent can be added into the sieve drum 82 through the input assembly 9, so that the two are separated. When there are organic pollutants in the slurry, gas is filled into the sieve drum 82 through the input assembly 9, so that bubbles are generated. The inflation can provide oxygen to support microbial activity or promote the diffusion of oxidizing agents, thereby improving the processing efficiency.
[0059] In one embodiment: a plurality of guide grooves 86 are formed in the outer wall of the sieve drum 82, and the trajectories of the guide grooves 86 are inclined from top to bottom.
[0060] The working principle and beneficial effects of the above technical solution are that the solid substances in the coal washing slurry are gradually thrown downward below the centrifugal cylinder 4 by the centrifugal force and the guidance of the guide grooves 86.
[0061] In one embodiment: the cross section of the protective plate 85 is trapezoidal, the longer base of the trapezoid is located above the gear ring 65, and the protective plate 85 is made of a flexible corrosion-resistant material.
[0062] The working principle and beneficial effects of the above technical solution are that the solid substances may be thrown out of the centrifugal cylinder 4 and then fall onto the gear ring 65. Through the special-shaped protective plate 85, the hard solid substances can be prevented from directly impacting the gear ring 65 to cause damage to it. At the same time, the accumulation of fluid-like solid substances on the gear ring 65 can be reduced, so that the gear ring 65 does not fail to rotate. Through the flexible protective plate 85, when the hard solid substances fall, they can be bounced to the outside by the elasticity of the protective plate 85, reducing the damage to the gear ring 65. When the fluid substances flow down, they may stay on the protective plate 85 for a long time due to the slow flow speed, and such substances may have strong corrosion. Through the corrosion-resistant protective plate 85, the protection effect can be improved.
[0063] In one embodiment: the discharging pipe 93 is composed of an inclined lower section, a horizontal section and an inclined upper section, and the length of the inclined lower section is greater than that of the inclined upper section.
[0064] The working principle and beneficial effects of the above technical solution are as follows: Since the discharge pipe 93 is located in the slurry for a long time, it is more prone to the problem of slurry backflow. If the slurry pressure in the screen barrel 82 is greater than the external pressure, it may cause slurry backflow, which in turn leads to contamination of the dispersant. The discharge pipe 93 in this device is designed with a downward inclined section, a horizontal section and an upward inclined section, and the length of the downward inclined section is greater than the length of the upward inclined section. This ensures that the liquid level at the feed point of the discharge pipe 93 is always higher than the height of the slurry. Through the principle of the connector, it can be ensured that the slurry cannot backflow. At the same time, the discharge pipe 93 is oriented towards the opening of the cover plate 81. Liquid or gas can be injected through the discharge pipe 93 so that the suspended solids accumulated on the liquid surface can more easily enter the space between the screen barrel 82 and the centrifuge barrel 4, thereby improving the separation efficiency.
[0065] Working principle and usage process: Add the mud to be treated into the device, place the mud into the blocking component 8, and then start the drive component 6. At this time, the drive motor 63 on the support rod 61 will drive the gear 64 to rotate. When the gear 64 rotates, it will drive the gear ring 65 that meshes with it to move, thereby driving the centrifuge cylinder 4 to rotate. The solid and liquid substances in the mud inside can be separated by centrifugation through rotation.
[0066] The screen 82 of the blocking component 8 separates the solid and liquid. The liquid is located inside the screen 82 and the solid is located outside the screen 82. Both the circular trough and the discharge trough 401 are equipped with opening devices. The opening devices can be pneumatic valves or electric valves. When cleaning is required, the valves can be opened to output the separated solid and liquid substances for further processing.
[0067] Based on the above, when it is necessary to clean the inside of the centrifuge drum 4, the control component 7 is activated. The irregular rod 72 on the column 71 is equipped with a winder 73, and the winder 73 is located at the center of the centrifuge drum 4. When the winder 73 is activated, the winder 73 will rotate, which will cause the hanging rope 74 wound on it to shorten, thereby causing the blocking component 8 to rise, so that the blocking component 8 can be separated from the centrifuge drum 4, and the centrifuge drum 4 and the blocking component 8 can be cleaned separately.
[0068] In addition, the slurry is injected into the inside of the screen barrel 82. Since the screen barrel 82 is suspended inside the centrifuge cylinder 4 by the control component 7, the screen barrel 82 will not move when the centrifuge cylinder 4 rotates. However, the slurry inside will move under the action of centrifugal force. At this time, the denser solid matter will be thrown to the outside, and the less dense liquid matter will be located on the inside. Under the action of the blocking block 83, the solid matter will be easily thrown into the space between the screen barrel 82 and the centrifuge cylinder 4, and then reach the bottom under the action of gravity, and can be discharged. At the same time, when there is a lot of liquid in the space between the screen barrel 82 and the centrifuge cylinder 4, the blocking block 83 can reduce the probability of solid matter re-entering the screen barrel 82.
[0069] Furthermore, since the cross-section of the blocking block 83 is triangular, and the curvature of the part located inside the sieve barrel 82 is smaller, while the curvature of the part located outside the sieve barrel 82 is larger, when solid material comes into contact with the part with smaller curvature, it will be easier to slide out from there. When solid material from the outside comes into contact with the part with larger curvature, it will be easier to be blocked by the blocking block 83 with larger curvature, reducing the probability of it flowing back into the sieve barrel 82.
[0070] Because the processing is continuous and the operation is not limited to simple separation, some staff cannot focus on the separation work continuously. At this time, when the centrifuge drum 4 is relatively full, some low-density solids that are not discharged in time will float on the liquid surface between the centrifuge drum 4 and the screen 82. Under the centrifugal force, these substances may be thrown out of the centrifuge drum 4 and fall onto the toothed ring 65. The special-shaped protective plate 85 can prevent hard solids from directly impacting the toothed ring 65 and causing damage. At the same time, it can reduce the accumulation of fluid solids on the toothed ring 65, which could lead to its rotation failure.
[0071] It is worth noting that the feed pipe 91 on the input component 9 is connected to an external pipe. External fluid substances enter the cavity of the cover plate 81 through the feed pipe 91, then enter the fixed block 92, and finally enter the screen barrel 82 through the discharge pipe 93. The external substances can be selected according to the needs. When there are many pyrite and sulfide particles in the mud, they are easily oxidized to generate Fe(OH)3 colloid, which increases the viscosity of the mud and makes it difficult to separate the solid and liquid. In this case, a separating agent or reducing agent can be added to the screen barrel 82 through the input component 9 to separate the two. When there are organic pollutants in the mud, gas is introduced into the screen barrel 82 through the input component 9 to generate bubbles. The gas can provide oxygen, support microbial activity or promote the diffusion of oxidants, and improve the treatment efficiency.
[0072] Finally, since the discharge pipe 93 is located in the slurry for a long time, it is more prone to slurry backflow. If the slurry pressure inside the screen 82 is greater than the external pressure, it may cause slurry backflow, which in turn leads to contamination of the dispersant. The discharge pipe 93 in this device is designed with a downward inclined section, a horizontal section, and an upward inclined section, with the length of the downward inclined section being greater than the length of the upward inclined section. This ensures that the liquid level at the feed inlet of the discharge pipe 93 is always higher than the slurry level. Through the principle of the connector, it can be ensured that the slurry cannot backflow. At the same time, the discharge pipe 93 is oriented towards the opening of the cover plate 81. Liquid or gas can be injected through the discharge pipe 93 to make it easier for some suspended solids accumulated on the liquid surface to enter the space between the screen 82 and the centrifuge 4, thereby improving the separation efficiency.

The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
