DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0034] Combination Figure 1 and Figure 4As shown, a device for cleaning suspended materials in a steel silo described in an embodiment of the present invention comprises a placement table 2, a plurality of legs 1 are fixedly connected to the lower outer edge of the placement table 2, a steel silo 3 is fixedly connected to the inner surface of the placement table 2, a steam pipe 4 is installed at the outer periphery of the steel silo 3, the end of the steam pipe 4 extends into the steel silo 3, a plurality of ventilation pipes 6 are inserted into the wall of the steel silo 3, an inner ring layer is installed at the outer periphery of the ventilation pipe 6, the inner ring layer is used to connect the plurality of ventilation pipes 6, a connecting pipe 5 is installed at the outer periphery of the inner ring layer, the connecting pipe 5 penetrates the steel silo 3 and is connected with the steam pipe 4, the inner ring layer is sleeved on the outside of the ventilation pipe 6, a cover plate 7 is installed on the top of the steel silo 3, a scraping assembly is installed on the lower surface of the cover plate 7, and the scraping assembly is used to promote cleaning of suspended materials on the inner surface of the steel silo 3.

[0035] During operation, when it is necessary to clean the wet suspended material in the steel silo, the embodiment of the present invention is used to first turn on the steam switch, and steam is passed into the steel silo 3 from the center thereof through the steam pipe 4, and the steam is introduced into the wall of the steel silo 3 through the connecting pipe 5. When the steam enters the steel silo 3 and the wall, the temperature of the wet suspended material on the inner surface of the steel silo 3 changes, and the steam liquefies to form condensed water. Since the sludge and mixed materials on the suspended material are generally alkaline, a slippery water layer is formed on the silo wall. The wet suspended material loses its adsorption force with the silo wall and slides to the bottom of the silo. Finally, the wet suspended material is discharged into the recycling object through the opening at the bottom of the steel silo 3, thereby solving the problem of the suspended material of the sludge. It should be noted that a steam switch is installed at the bottom of the steam pipe 4, and the recycling object is an existing bucket or basin or other object.

[0036] In the process of cleaning suspended materials, the speed at which the suspended materials fall is relatively limited only by the condensation of steam. When it is necessary to further promote the sliding of the wet suspended materials, the scraping component is powered on to start working. The scraping component moves from top to bottom along the inner surface of the steel silo 3. The scraping component squeezes the wet suspended materials on the inner surface of the steel silo 3. After friction, the wet suspended materials are separated from the inner surface of the steel silo 3, so that the wet materials fall down quickly, thereby having the function of promoting the cleaning of the wet suspended materials.

[0037] like Figures 7 and 8 As shown, the scraping assembly includes an electric telescopic rod 71, the bottom end of the electric telescopic rod 71 is fixedly connected to an assembly ring 73, the outer periphery of the assembly ring 73 is fixedly connected to a scraper 72, and the scraper 72 is connected to the inner surface of the steel silo 3; the cross section of the scraper 72 is wedge-shaped, and the lower end of the scraper 72 is set to be sharp;

[0038] During operation, when the wet suspended materials are to be recovered quickly, the embodiment of the present invention is used, the electric telescopic rod 71 is extended after being energized, the electric telescopic rod 71 pushes the assembly ring 73 to move downward, and the assembly ring 73 drives the scraper 72 to move synchronously. When the scraper 72 moves downward, it gradually squeezes against the inner wall of the steel silo 3, and the wet suspended materials on the inner surface of the steel silo 3 are gradually and quickly separated, thereby promoting the recovery of the wet suspended materials and improving the working efficiency of cleaning the inner surface of the steel silo 3.

[0039] like Figures 8 to 10 As shown, a driving assembly is also installed on the inner surface of the assembly ring 73, and the driving assembly includes a hanging ring 731, and the hanging ring 731 includes a mounting block and a collar rod. The end of the collar rod is sleeved with a lower rotating shaft 732, and the outer periphery of the lower rotating shaft 732 is fixedly connected to a first gear 733. The upper surface of the scraper 72 is provided with a plurality of mounting grooves, and a plurality of rotating wheels 735 are connected inside the plurality of mounting grooves. An upper rotating shaft 734 is fixedly connected at the center of the plurality of rotating wheels 735, and a plurality of snap rings 736 are fixedly connected to the outer surface of the upper rotating shaft 734, and a connecting rope 737 is wound around the outer surface of the snap ring 736; the other end of the connecting rope 737 is wound around the lower rotating shaft 732, and the diameters of the plurality of rotating wheels 735 are flush with the outer edge of the mounting groove;

[0040] During operation, after the scraper 72 cleans the wet suspended material on the inner surface of the steel silo 3, it will be reset upwards for the convenience of the next use. When resetting upwards, the scraper 72 will be adhered with wet suspended material due to the friction of the wet suspended material, and a small amount of wet suspended material will be wiped back when it contacts the inner surface of the steel silo 3, resulting in poor cleaning effect and affecting subsequent recycling. Before dealing with this problem, it is necessary to ensure the driving force for cleaning the wet suspended material. When using the embodiment of the present invention, the scraper 72 will drive the rotating wheel 735 to move synchronously when it moves from top to bottom, and the rotating wheel 735 The friction with the inner surface of the steel silo 3 causes the rotating wheel 735 to rotate, and when the rotating wheel 735 rotates, it drives the upper rotating shaft 734 to work, and the upper rotating shaft 734 drives the retaining ring 736 to rotate. When the retaining ring 736 rotates, it gradually pulls the connecting rope 737 to move. After the connecting rope 737 is pulled, it drives the lower rotating shaft 732 through the friction force, and then the upper rotating shaft 734 and the lower rotating shaft 732 are linked to each other, and the force generated when the scraper 72 moves is used to complete the synchronous driving of the upper rotating shaft 734 and the lower rotating shaft 732; it should be noted that the hanging ring 731 provides a firm support for the lower rotating shaft 732.

[0041] like Figure 10 to Figure 11 As shown, a cleaning assembly is also installed on the outer surface of the lower rotating shaft 732, which is used to wipe the scraper 72 after scraping the suspended material, so as to prevent the small amount of suspended material contained in the scraper 72 from being wiped back to the inner surface of the steel silo 3 during the upward resetting process. The cleaning assembly also includes a first fixed plate 738 connected to the surface of the lower rotating shaft 732, the outer surface of the first gear 733 is meshed with the second gear 739, the outer surface of the second gear 739 is meshed with the third gear 740, and the centers of the second gear 739 and the third gear 740 are both provided with a rotating rod, and the two ends of the first fixed plate 738 are respectively sleeved on the outer periphery of the lower rotating shaft 732 and the rotating rod of the second gear 739, and a second fixed plate 741 is sleeved between the two rotating rods of the second gear 739 and the third gear 740, and the outer periphery of the rotating rod of the third gear 740 is fixedly connected with an action bar 742, and a cleaning plate 743 is installed on the side of the action bar 742; the first fixed plate 738 is fixedly connected to the second fixed plate 741.

[0042] During operation, when it is necessary to clean the wet suspended material that is wiped back when the scraper 72 is reset, the embodiment of the present invention is used. When the rotating wheel 735 rubs against the inner surface of the steel silo 3, the rotating wheel 735 rotates counterclockwise, and the rotating wheel 735 drives the upper rotating shaft 734 and the clamping ring 736 to rotate, and pulls the lower rotating shaft 732 to rotate through the clamping ring 736 and the connecting rope 737. The lower rotating shaft 732 rotates synchronously with the first gear 733, the first gear 733 is meshed with the second gear 739, the second gear 739 rotates counterclockwise, and the second gear 739 is meshed with the third gear 740. The rotation of the third gear 740 drives the rotating rod to move synchronously. The deflection of the rotating rod of the third gear 740 drives the action bar 742 and the cleaning plate 743 to rotate synchronously. The cleaning plate 743 wipes outward with the scraper 72, thereby wiping off the moist suspended material adhering to the outside of the scraper 72, thereby achieving a more thorough cleaning effect. It should be noted that the first fixed plate 738 and the second fixed plate 741 play a role in preventing separation, and a torsion spring is arranged between the action bar 742 and the rotating rod of the third gear 740, and with the action of steam and shaking, the moist suspended material above the third gear 740 is prevented from forming accumulation.

[0043] like Figures 5 and 6 As shown, a plurality of limit grooves are installed on the lower surface of the cover plate 7 and at the end of the vent pipe 6, and a steam component is installed in the plurality of limit grooves. The steam component is used to pass steam into the steel silo 3. The steam component includes a shell 61 installed at the end of the vent pipe 6, a nozzle 62 is fixedly connected below the shell 61, and a spray hole is opened at the end of the nozzle 62. An air plate 66 is slidably arranged inside the vent pipe 6, a push rod 67 is fixedly connected to the top of the air plate 66, a connecting rod 68 is fixedly connected to the end of the push rod 67, and the other end of the connecting rod 68 away from the push rod 67 is fixedly connected to the center column 6 3. A blocking plate 64 is fixedly connected to the bottom end of the center column 63, two compression springs 65 are installed between the blocking plate 64 and the shell 61, a plurality of blocking strips corresponding to the spray holes of the nozzle 62 are arranged at the bottom of the blocking plate 64, and a shunt pipe 69 is installed between the vent pipe 6 and the nozzle 62; through holes matching with the push rod 67 and the center column 63 are respectively opened on the lower surface of the shell 61, and the push rod 67 and the center column 63 can pass through the through holes and extend to the inside of the shell 61; it should be noted that the inside of the nozzle 62, the vent pipe 6 and the shell 61 are all cavities.

[0044] During operation, the end of the nozzle 62 is easily blocked by contact with the material in the steel silo 3, causing the problem of material accumulation. When using the embodiment of the present invention, the blocking strip of the blocking plate 64 is initially extended into the nozzle hole of the nozzle 62, thereby preventing the material stored in the steel silo 3 from entering the nozzle hole of the nozzle 62 and causing the nozzle 62 to be blocked; the steam enters the interior of the steel silo 3 and the vent pipe 6, and the steam in the vent pipe 6 moves upward. The gas plate 66 is initially located below the connecting hole between the shunt pipe 69 and the vent pipe 6. After the steam is introduced, it pushes the gas plate 66 to move upward, and the gas plate 66 pushes the push rod 67 to move upward. The push rod 67 drives the center column 63 to move upward synchronously through the connecting rod 68, and the blocking plate 64 moves accordingly. After the blocking plate 64 and the center column 63 rise, the blocking strip of the blocking plate 64 no longer blocks the nozzle hole of the nozzle 62, and the connecting rod 68 moves upward to the top wall of the shell 61 and stops;

[0045] When the air plate 66 is pushed to a level higher than the bypass pipe 69 inserted into the vent pipe 6 and the connecting hole of the vent pipe 6, the gas enters the area between the sealing plate 64 and the inner bottom wall of the nozzle 62 through the bypass pipe 69. At this time, the gas in the bypass pipe 69 is ejected downward through the bottom end of the nozzle 62 to perform steam treatment on the inside of the steel silo 3. At the same time, due to the downward jet of the nozzle 62, the inner wall of the spray hole of the nozzle 62 is cleared to prevent the spray hole of the nozzle 62 from being blocked.

[0046] like Figure 12 to Figure 13 As shown, a shaking assembly is installed on the inner wall between the steel silo 3 and the placement platform 2, and the shaking assembly includes a fixed ring 31, an elastic gasket 32 ​​is fixedly connected to the top of the fixed ring 31, and a plurality of reset springs 33 and a plurality of knocking plates 34 are fixedly connected to the lower part of the outer edge of the elastic gasket 32; the bottom end of the reset spring 33 is fixedly connected to the fixed ring 31, and the diameter of the fixed ring 31 is larger than that of the elastic gasket 32. In the initial state, the elastic gasket 32 ​​does not contact the inner wall between the steel silo 3 and the placement platform 2.

[0047] During operation, since the steel silo 3 is composed of a columnar and conical structure, the scraper 72 scrapes the wet suspended material. After the wet suspended material is scraped off, it is easy to adhere to the space between the column and the cone, and there will be residues during cleaning. When using the embodiment of the present invention, the scraper 72 moves downward and is squeezed by the elastic gasket 32. The elastic gasket 32 ​​is squeezed and deformed, and the elastic gasket 32 ​​expands outward. The elastic gasket 32 ​​drives the knocking plate 34 to move synchronously, and the knocking plate 34 moves outward and collides with the inner wall of the steel silo 3. The two shake after the collision, thereby shaking out the wet suspended material residue between the column and the cone, and accelerating the recovery of the suspended material downward; it should be noted that the elastic gasket 32 ​​is located above the column and the cone.

[0048] Working principle: When the wet suspended material is to be recovered quickly, the embodiment of the present invention is used, the electric telescopic rod 71 is extended after being energized, the electric telescopic rod 71 pushes the assembly ring 73 to move downward, the assembly ring 73 drives the scraper 72 to move synchronously, and the scraper 72 gradually squeezes the inner wall of the steel silo 3 when moving downward, and the wet suspended material on the inner surface of the steel silo 3 is gradually and quickly separated, thereby promoting the recovery of the wet suspended material and improving the working efficiency of cleaning the inner surface of the steel silo 3;

[0049] After the scraper 72 cleans the wet suspended material on the inner surface of the steel silo 3, it will be reset upwards for the convenience of the next use. When resetting upwards, the scraper 72 will be adhered with wet suspended material due to the friction of the wet suspended material, and a small amount of wet suspended material will be wiped back when it contacts the inner surface of the steel silo 3, resulting in poor cleaning effect and affecting subsequent recycling. Before dealing with this problem, it is necessary to ensure the driving force for cleaning the wet suspended material. In the embodiment of the present invention, the scraper 72 will drive the rotating wheel 735 to move synchronously when it moves from top to bottom, and the rotating wheel 735 and the steel silo will move synchronously. The inner surface of the bin 3 is rubbed, and the rotating wheel 735 rotates. When the rotating wheel 735 rotates, it drives the upper rotating shaft 734 to work, and the upper rotating shaft 734 drives the clamping ring 736 to rotate. When the clamping ring 736 rotates, it gradually pulls the connecting rope 737 to move. After the connecting rope 737 is pulled, the friction force drives the lower rotating shaft 732, and then the upper rotating shaft 734 and the lower rotating shaft 732 are linked. The force generated when the scraper 72 moves completes the synchronous driving of the upper rotating shaft 734 and the lower rotating shaft 732; it should be noted that the hanging ring 731 firmly supports the lower rotating shaft 732;

[0050] When it is necessary to clean the wet suspended material that is wiped back when the scraper 72 is reset, the embodiment of the present invention is used. When the rotating wheel 735 rubs against the inner surface of the steel silo 3, the rotating wheel 735 rotates counterclockwise, and the rotating wheel 735 drives the upper rotating shaft 734 and the clamping ring 736 to rotate, and pulls the lower rotating shaft 732 to rotate through the clamping ring 736 and the connecting rope 737. The lower rotating shaft 732 rotates synchronously with the first gear 733, the first gear 733 is meshed with the second gear 739, the second gear 739 rotates counterclockwise, the second gear 739 is meshed with the third gear 740, and the third gear 740 is meshed. The rotation of the wheel 740 drives the rotating rod to move synchronously, and the deflection of the rotating rod of the third gear 740 drives the action bar 742 and the cleaning plate 743 to rotate synchronously, and the cleaning plate 743 wipes the scraper 72 outward, thereby wiping off the wet suspended material adhering to the outer side of the scraper 72, which has a more thorough cleaning effect; it should be noted that the first fixed plate 738 and the second fixed plate 741 play a role in preventing separation, and a torsion spring is provided between the action bar 742 and the rotating rod of the third gear 740, and with the action of steam and shaking, the wet suspended material above the third gear 740 is prevented from forming accumulation;

[0051] The end of the nozzle 62 is easily blocked by contact with the material in the steel silo 3, causing the problem of material accumulation. When using the embodiment of the present invention, the blocking strip of the blocking plate 64 is initially extended into the nozzle hole of the nozzle 62, thereby preventing the material stored in the steel silo 3 from entering the nozzle hole of the nozzle 62 and causing the nozzle 62 to be blocked; the steam enters the interior of the steel silo 3 and the vent pipe 6, and the steam in the vent pipe 6 moves upward. The gas plate 66 is initially located below the connecting hole between the shunt pipe 69 and the vent pipe 6. After the steam is introduced, it pushes the gas plate 66 to move upward, and the gas plate 66 pushes the push rod 67 to move upward. The push rod 67 drives the center column 63 to move upward synchronously through the connecting rod 68, and the blocking plate 64 moves accordingly. After the blocking plate 64 and the center column 63 rise, the blocking strip of the blocking plate 64 no longer blocks the nozzle hole of the nozzle 62, and the connecting rod 68 moves upward to the top wall of the shell 61 and stops;

[0052] When the air plate 66 is pushed to a level higher than the bypass pipe 69 inserted into the vent pipe 6 and the connecting hole of the vent pipe 6, the gas enters the area between the sealing plate 64 and the inner bottom wall of the nozzle 62 through the bypass pipe 69. At this time, the gas in the bypass pipe 69 is ejected downward through the bottom end of the nozzle 62 to perform steam treatment on the inside of the steel silo 3. At the same time, due to the downward jet of the nozzle 62, the inner wall of the spray hole of the nozzle 62 is cleared to prevent the spray hole of the nozzle 62 from being blocked.

[0053] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
