AI Technical Summary
The existing central feeder is prone to blockage when coal wet, coal sludge and coal sludge are mixed, resulting in problems such as arches and sludge, which cannot be effectively avoided.
A three-scraper material silo anti-blocking machine is designed, including a silo bucket, an upper scraper, a lower scraper and an intermediate scraper. These scrapers are installed on the rotary ring. The rotary ring is rotated by the driving system. The scraper forms relative movement with the inner wall of the silo bucket, and the blind spots of the material and the silo body are removed.
Through the relative movement of the three sets of scrapers, the blind spots of the material and the bin body can be effectively removed, avoid blockage, and the flow and whereabouts of the material without blind spots can be achieved.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of silos, and particularly relates to a three-scraper material silo anti-blocking machine. Background Art
[0002] At present, common central feeders mainly consist of a discharge chassis, a discharge inner cone, a discharge arm, a central discharge tube, a drive system, a lubrication system, an electric control system and other parts. Due to structural limitations, the central feeder cannot utilize the natural flow and natural fall of materials, and can only adopt forced feeding. In the case of wet coal, co-firing of coal slime and coal slime, coal blockage is still inevitable. Therefore, this blind area of blockage will form arches and coal bridging from time to time, which cannot be avoided. Content of the Utility Model
[0003] In view of the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a three-scraper material silo anti-blocking machine, which can form relative movement for both the material and the cross-section of the silo body through three groups of scrapers, and each part has no blind area for blockage removal, with good effect.
[0004] To solve the above technical problem, the technical scheme adopted by the utility model is: a three-scraper material silo anti-blocking machine, including a silo barrel, an upper scraper, a lower scraper and an intermediate scraper. A rotating ring is rotatably arranged inside the silo barrel, and a drive system for driving the rotating ring to rotate is installed outside the silo barrel. The upper scraper, the lower scraper and the intermediate scraper are all installed on the rotating ring, and the upper scraper, the lower scraper and the intermediate scraper respectively fit the upper, middle and lower inner walls of the silo barrel.
[0005] Two clamping grooves are provided on the rotating ring, and the upper scraper and the lower scraper are respectively clamped into the two clamping grooves.
[0006] The intermediate scraper is welded on the rotating ring.
[0007] The rotating ring is connected to the silo barrel through a slewing bearing.
[0008] The cross-section of the silo barrel is arranged in an inverted conical shape.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] For the three-scraper material silo anti-blocking machine of the utility model, by setting the upper scraper, the lower scraper and the intermediate scraper, and respectively fitting the upper, middle and lower inner walls of the silo barrel, when the rotating ring rotates, the upper scraper, the lower scraper and the intermediate scraper form relative movement for both the material and the cross-section of the silo barrel, and each part has no blind area for blockage removal, with good effect.

[0013] Markings in the figure: 1, silo barrel; 2, upper scraper; 3, lower scraper; 4, middle scraper; 5, drive system; 6, card slot; 7, rotating ring. Specific embodiments
[0014] In order to make the above features and advantages of the present utility model more obvious and understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings.
[0015] As Figure 1 and Figure 2 shown, this embodiment provides a three-scraper material silo anti-blocking machine, including a silo barrel 1, an upper scraper 2, a lower scraper 3 and a middle scraper 4. A rotating ring 7 is rotatably arranged in the silo barrel 1, and a drive system 5 for driving the rotating ring 7 to rotate is installed outside the silo barrel 1. The upper scraper 2, the lower scraper 3 and the middle scraper 4 are all installed on the rotating ring 7, and the upper scraper 2, the lower scraper 3 and the middle scraper 4 respectively fit the upper, middle and lower inner walls of the silo barrel 1. Specifically, the rotating ring 7 is connected to the silo barrel 1 through a slewing bearing. The driving end of the drive system 5 is connected with a speed reducer, the output end of the speed reducer is connected with a small gear, the small gear is drivingly connected with the outer ring of the slewing bearing, and the outer ring of the slewing bearing is fixed to the rotating ring 7, so as to rotate together. By providing the upper scraper 2, the lower scraper 3 and the middle scraper 4 and respectively fitting the upper, middle and lower inner walls of the silo barrel 1, when the rotating ring 7 rotates, relative movements are formed between the upper scraper 2, the lower scraper 3, the middle scraper 4 and the cross-section of the material and the silo barrel 1, and each part is unblocked without blind spots, and the effect is good.
[0016] Furthermore, two card slots 6 are provided on the rotating ring 7, and the upper scraper 2 and the lower scraper 3 are respectively clamped into the two card slots 6. Connected in the way of the card slots 6, without bolts, the labor intensity is reduced and the trouble of locking bolts is avoided. People do not need to enter the silo, which greatly reduces the occurrence of safety accidents.
[0017] Furthermore, the middle scraper 4 is welded to the rotating ring 7. The middle scraper 4 can be stably fixed.
[0018] Furthermore, the cross-section of the silo barrel 1 is arranged in an inverted conical shape. The material can flow and fall naturally along the side wall of the silo barrel 1 by using the gravity through its characteristics.
[0019] The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
