Description

Technical Field

[0001] The utility model relates to a wet coal slime dispersing device for preventing stones from getting stuck, and belongs to the field of coal slime dispersing. Background Art

[0002] The common breaking device in the industry is basically composed of a silo body and a breaking screw. Due to the high viscosity of wet coal slime, after the loader shovels it into the silo, it is usually stuck together as a whole. It must be broken into small pieces by a double-axis breaking screw, fall into a belt conveyor, and transported to a dryer for drying. For wet coal slime without debris, the above structure can basically meet production needs.

[0003] However, in the mountainous areas of southwest my country, the geology is mostly rocky. A large number of stones will be mixed into the wet coal slime during the stacking, loading and transportation process. The existing feeding and breaking device is often stuck due to the mixing of large stones, and even the breaking spiral blades and the bearing seats at both ends are damaged due to overload, causing feeding stagnation. The time for clearing stones and maintenance usually takes 2-3 days or even longer, which directly affects production efficiency and leads to a decrease in coal slime output. Since it is necessary to manually climb into the warehouse for cleaning, it is also dangerous. Utility Model Content

[0025] The drive mode of the breaking spiral variable frequency drive motor and the push-pull component is adopted, which can make the active breaking component and the driven breaking component work together, thereby improving the working efficiency and stability.

[0026] By arranging push-pull components on the frames on both sides of the silo body and using dovetail sliding guide rails 14, slide cylinders 9 and sliding bearing seats 8, the push-pull movement is smoother, avoiding the impact of problems such as sticking or excessive friction on the operation of the device.

[0027] The invention has the advantages of simple structure, low manufacturing cost, easy operation and maintenance, and can realize automatic control, thereby improving production efficiency and product quality and reducing production cost and manual operation error.

[0028] The active dispersing component includes an active dispersing spiral shaft 5, active dispersing blades, a driving end fixed bearing seat 2 and a tail fixed bearing seat 7. Both ends of the active dispersing spiral shaft 5 pass through the silo body 12. One end of the active dispersing spiral shaft 5 is rotatably mounted on the frame through the tail fixed bearing seat 7, and the other end forms a driving end and is rotatably mounted on the frame through the driving end fixed bearing seat 2. The driving end of the active dispersing spiral shaft 5 is driven by a dispersing spiral variable frequency drive motor 1; a driving gear 3 is installed on the active dispersing spiral shaft 5 close to the dispersing spiral variable frequency drive motor 1, and the active dispersing blades are covered on the active dispersing spiral shaft 5 located in the silo body.

[0029] The active breaking up spiral shaft, active breaking up blades and active gear components are adopted to improve the coal slime crushing effect, break up the carried stones, and enhance the fluidity and handleability of the coal slime.

[0030] The support and fixation of the fixed bearing seat at the driving end and the fixed bearing seat at the tail end make the rotation of the active breaking up spiral shaft more stable and reliable, reduce vibration and noise, and extend the service life of the device; the use of the breaking up spiral variable frequency drive motor can freely adjust the speed and power according to the different properties and processing requirements of the coal slime, achieve energy saving and consumption reduction, and reduce production costs and environmental pollution.

The active shaft sliding taper sleeve 13 is threadedly matched with the active breaking up spiral shaft 5 and dynamically matched with the conical surfaces of the driving end fixed bearing seat 2 and the tail fixed bearing seat 7.

[0032] The driven dispersing component includes a driven dispersing screw shaft 6, driven dispersing blades and a driven shaft sliding cone sleeve. After the two ends of the driven dispersing screw shaft 6 pass through the silo body 12, one end is rotatably installed on one of the sliding bearing seats 8, and the other end is rotatably installed on the other sliding bearing seat 8.

[0034] By adopting the setting of the silo door driving cylinder, the opening and closing of the silo door can be made faster and more accurate, avoiding errors and labor intensity during manual operation, and improving production efficiency and operational safety.

[0035] Installing a door driving cylinder hinge seat on the frame and hingedly connecting the door driving cylinder hinge seat to the cylinder body of the door driving cylinder can make the movement of the door driving cylinder more stable and smooth; installing a door hinge seat on the silo door and hingedly connecting the telescopic rod of the door driving cylinder to the door hinge seat can make the opening and closing of the door more firm and precise.

[0036] The working principle of the utility model is:

[0037] When the coal slime enters the breaking screw for crushing, the crushed coal slime enters the belt conveyor below and is transported to the dryer for drying. When the coal slime entering the silo is mixed with stones, the large stones will get stuck between the active breaking screw shaft 5 and the driven breaking screw shaft 6 below. At this time, the breaking screw variable frequency drive motor 1 will be overloaded, and the load current will increase and then alarm and shut down. If PLC is used to control this equipment, the breaking screw variable frequency drive motor 1 can be set in the PLC to stop when the current reaches the preset value. If ordinary control is used, it is necessary to pay attention to manual shutdown after the current increases significantly.

[0038] After the breaking spiral variable frequency drive motor 1 is stopped, the driving shaft sliding cone sleeve 13 at both ends of the driving spiral shaft is first rotated to make it interfere with the cone surface of the driving end fixed bearing seat 2 and the tail fixed bearing seat 7, and the driven shaft sliding cone sleeve at both ends of the driven spiral shaft is interfered with the cone surface of the sliding bearing seat 8, so that the driving spiral shaft is locked with the driving end fixed bearing seat 2 and the tail fixed bearing seat 7, and the driven spiral shaft is locked with the sliding bearing seat 8, and then the warehouse door driving cylinder 11 is started to shrink and open the rotating warehouse door 10. After the rotating warehouse door 10 is rotated to the right position, the push rod of the sliding seat cylinder 9 is started to shrink and drag the sliding bearing seat 8, so that the driving gear 3 and the driven gear 4 gradually move away, and the main and driven gears will keep the meshing state away, and the gear meshing position remains unchanged. After disengagement, when the gap between the main and driven breaking spiral shafts is larger than the stone size, the stone falls into the belt conveyor below with the coal mud, and the stone is taken out manually. After the stones are cleared, start the sliding seat cylinder 9 to extend the telescopic rod and push the driven breaking screw shaft 6 until the main and driven gears are meshed, then energize and start the bin door driving cylinder 11 to close the bin door 10 in place, and finally rotate the driving shaft sliding cone sleeve back, loosen the cooperation between the driving shaft sliding cone sleeve and the cone surface of the driving end fixed bearing seat 2 and the tail fixed bearing seat 7, and loosen the cooperation between the driven screw shaft and the cone surface of the sliding bearing seat 8, and the stone cleaning is completed. Then the silo body can be started according to the normal feeding sequence.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
