Description

Technical Field

[0001] This utility model belongs to the technical field of sugarcane sugar refining equipment, specifically relating to a stable and reliable rotary automatic slag remover with simple structure, low vibration during slag removal, high efficiency, low failure rate, and large slag removal range. Background Technology

[0002] Bagasse is primarily used as fuel for boilers in sugarcane factories. Under normal pressing conditions, the sugar mill's pressing workshop sends bagasse directly to the boiler room for combustion. Excess bagasse is stored in a bagasse silo for later use. Only when the produced bagasse is insufficient is it returned from the silo and then transported to the boiler for combustion via a conveyor. Because bagasse is highly viscous and easily clumps together, manual bagasse removal is not only time-consuming to start the feedstock but also labor-intensive. Currently, loaders are generally used to assist manual bagasse removal for the return operation. However, directly returning bagasse with loaders can also cause blockages and bridging, requiring manual removal as well. Furthermore, the simultaneous operation of manual labor and loaders poses a significant safety hazard.

[0003] Existing technologies involve fixing rake teeth or scrapers at intervals on one or more chains, with a motor driving a sprocket to rotate, causing the rake teeth or scrapers to circulate and move bagasse above the conveyor belt of the bagasse return conveyor. However, this method has low efficiency and requires significant power. To address this, a double-trolley, double-beam bridge crane is installed in the bagasse storage area. This crane drives a suspended mobile rake to move up and down and back and forth, allowing for segmented processing of bagasse along the length of the storage area. While this method offers greater flexibility, the mobile rake, operating in a suspended manner, maintains vertical balance under its own weight, but lacks horizontal stability. This means that when the storage pile tilts or the bagasse clumps together, inconsistent forces can cause the rake to sway. This not only prevents the bagasse from falling accurately into the discharge port, exacerbating blockages, but also poses a significant safety hazard due to uncontrolled swaying.

[0004] To address the aforementioned problems in the existing technology, the applicant filed a patent with publication number CN218146744U entitled "An Automatic Bagasse Removal Machine for Sugarcane Bagasse Return." This patent utilizes a hinged support beam on a rotatable load-bearing frame, with a drive device on the support frame to drive the beam's pitching motion. This allows for free adjustment of the removal angle and position according to the bagasse pile's condition, offering greater flexibility and expanding the removal range. Furthermore, a synchronous transmission shaft driven by the drive device is installed on the support frame, along with two worm gear devices at the front and rear to drive the rake arms on both sides of the support. This causes the hinged rake frame and its rake teeth to reciprocate in a circular trajectory, gradually conveying the bagasse backward and allowing it to fall into the feed pipe. Because the transmission process involving the rake frame and its rake teeth has low friction and is lightweight, its driving power is low. Moreover, the minimal exposed moving structures and the fact that the rotating structures do not directly contact the bagasse prevent bagasse from sticking and causing jamming during normal operation. However, because all the rake teeth are concentrated on the left and right rake tooth frames, the total weight of the rake tooth mounting structure is as high as 300 kg, which leads to the following problems: 1. During high-speed reciprocating slag removal, the rake tooth frame generates a large reaction force, which easily causes the slag remover body to vibrate significantly, affecting the normal operation of other parts; 2. During high-speed reciprocating motion, the mounting structure will generate large periodic stresses, which will cause the rake tooth mounting frame to frequently deform or break, and the keyway of the reducer spindle is also prone to deformation and loosening, resulting in a high failure rate and reduced slag removal efficiency. Utility Model Content

[0005] This utility model addresses the problems and shortcomings of existing technologies by providing a stable and reliable rotary automatic slag remover with a simple structure, low slag removal vibration, high efficiency, low failure rate, and large slag removal range.

[0006] This utility model is implemented as follows: it includes a load-bearing support, a support beam, a reduction motor, and a slag discharge mechanism. The load-bearing support is vertically fixed at the upper end of the bagasse conveying port. The load-bearing support is provided with a drive mechanism for driving the support beam to move up and down. One end of the support beam is hinged to the lower part of the load-bearing support and the other end extends outward. The reduction motor is fixedly installed on the outer extension of the support beam.

[0007] The support beam includes a hollow square tube and a connecting crossbeam. Two hollow square tubes are arranged parallel to each other on both sides of the extension direction of the support beam. The connecting crossbeam is arranged horizontally above the hollow square tubes and its two ends are fixedly connected to the two hollow square tubes respectively.

[0008] The slag discharging mechanism includes a sprocket wheel, a chain, a harrow tooth shaft, and harrow teeth. A plurality of mutually parallel harrow tooth shafts are transversely arranged along the length direction of the support girder. The two ends of the harrow tooth shaft rotatably penetrate through the inner side walls of two hollow square tubes. The sprocket wheel is coaxially and fixedly connected to the harrow tooth shaft inside the hollow square tube. A main sprocket wheel is fixedly arranged on the output shaft of the reduction motor. The chain links the main sprocket wheel with the sprocket wheel and also links adjacent sprocket wheels. On the surfaces of the harrow tooth shafts inside the two hollow square tubes, multiple rows of harrow teeth are circumferentially and evenly distributed.

[0009] Further, the center distance between adjacent harrow tooth shafts of the support girder is less than the diameter of the rotation trajectory of the tooth tips of the harrow teeth. The rows of harrow teeth evenly distributed on the surfaces of adjacent harrow tooth shafts of the support girder are arranged in a staggered manner.

[0010] Further, at least two slag discharging mechanisms are sequentially arranged along the extending direction of the support girder. Each slag discharging mechanism corresponds to a reduction motor and is provided with at least 3 harrow tooth shafts at intervals. The main sprocket wheel is linked by a chain to the sprocket wheel fixedly connected to one or two harrow tooth shafts in the corresponding slag discharging mechanism. The sprocket wheel fixedly connected to the harrow tooth shaft is linked by a chain to the sprocket wheels of the harrow tooth shafts on the front side and / or the rear side.

[0011] Further, the two hollow square tubes of the support girder and the connecting cross beam form an "H" shape, a "day" shape or an "eye" shape structure. At both ends of the connecting cross beam, connecting rods are respectively and perpendicularly fixedly arranged. The ends of the connecting rods far from the connecting cross beam are fixedly connected to the hollow square tubes. The connecting cross beam is arranged outside the rotation trajectory of the tooth tips of adjacent harrow teeth.

[0012] Further, two sprocket wheels are coaxially and spacedly fixedly arranged at one end of the harrow tooth shaft, and the inner sprocket wheel is linked to the inner sprocket wheel of the adjacent harrow tooth shaft in the front or rear, and the outer sprocket wheel is linked to the outer sprocket wheel of the adjacent harrow tooth shaft in the rear or front; or sprocket wheels are respectively coaxially fixedly arranged at both ends of the harrow tooth shaft, and the sprocket wheels at both ends of the harrow tooth shaft are alternately linked to the sprocket wheels of the adjacent harrow tooth shafts on the front side and the rear side.

[0013] Further, multiple harrow tooth frames parallel to the axis of the harrow tooth shaft are circumferentially and evenly distributed on the surface of the harrow tooth shaft inside the support girder. The harrow teeth are vertically and fixedly arranged on the harrow tooth frames at intervals.

[0014] Further, both ends of the hollow square tube are closed, and a maintenance port and a cover plate with a gasket for covering the maintenance port are provided on the outer side wall and / or the upper side wall corresponding to the sprocket wheel. A relief port for the chain is also provided on the upper side wall of the hollow square tube below the main sprocket wheel.

[0015] Further, bearing seats for supporting the harrow tooth shaft are respectively arranged on the inner side walls of the two hollow square tubes. One end of the harrow tooth shaft facing the sprocket wheel passes through the bearing seat and extends into the hollow square tube.

[0016] Furthermore, the present invention also includes a rotary base straddling the bagasse conveyor, wherein a feed pipe is provided inside the rotating coil of the rotary base, the load-bearing bracket is vertically fixed at the top of the rotating coil, and a first driving device for driving the rotating coil to rotate is provided on one side of the rotary base.

[0017] Furthermore, a second driving device is fixedly installed on the moving coil or the load-bearing bracket, and a shaftless spiral blade extending downward into the feed tube is connected to the drive shaft of the second driving device.

[0018] The link described in this invention is a connection between a chain and a sprocket.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. The rake roller of this utility model, consisting of a rake shaft and rake teeth, is set between two hollow square tubes and driven by a chain. Therefore, the structure of the rake roller is not only simpler than that of a rake rotation structure composed of several parts, but also lighter in total weight. This effectively reduces the reaction force generated by the rake roller when rakes slag at high speed, resulting in less vibration of the slag remover body. Furthermore, the support beam is composed of two hollow square tubes and a connecting beam connecting the two hollow square tubes. As a result, the overall rigidity is stronger than that of the existing single-arm support beam, which can also effectively suppress the vibration generated by the slag remover body, and ultimately reduce or even eliminate the adverse effects of vibration on the normal operation of other parts.

[0021] 2. Because the rake roller of this utility model has a light total weight, the periodic stress generated on the installation structure during high-speed rotation and slag removal is small. Moreover, the overall rigidity of the support beam is relatively strong. Furthermore, the rake teeth are installed on rollers supported by two hollow square tubes, which can reduce the uneven force on both sides of the support beam. This can effectively slow down or even avoid deformation and breakage of the rake roller, thus improving the reliability of the rake roller.

[0022] 3. The rake teeth of this utility model transmit power through a flexible chain drive. Compared with the rigid power transmission structure of the synchronous drive shaft connected to the worm gear device, the vibration and periodic stress on the rake teeth can be avoided from being transmitted to the geared motor. This can prevent the keyway of the geared motor shaft and sprocket shaft from deforming or loosening, and further improve the reliability and slag removal efficiency of the slag remover.

[0023] 4. This utility model sets the transmission sprocket and chain that drive the rake roller to rotate inside the hollow square tube, so that the chain transmission mechanism does not come into direct contact with the bagasse. This significantly reduces the exposed moving structure, thus avoiding bagasse sticking and affecting normal operation and causing jamming. It effectively reduces abnormal downtime and improves the reliability and efficiency of the bagasse remover.

[0024] Therefore, this utility model has the characteristics of simple structure, low vibration during slag removal, high efficiency, low failure rate, and large slag removal range. Attached Figure Description

One end of the connecting rod 23 far from the connecting cross beam 22 is fixedly connected to the hollow square tube 21. The connecting cross beam 22 is arranged outside the rotation locus 46 of the tips of adjacent harrow teeth 44.

[0037] Two sprocket wheels 41 are coaxially and spacedly fixedly arranged at one end of the harrow tooth shaft 43. The inner sprocket wheel 41 is linked to the inner sprocket wheel 41 of the adjacent harrow tooth shaft 43 in the front or rear, and the outer sprocket wheel 41 is linked to the outer sprocket wheel 41 of the adjacent harrow tooth shaft 43 in the rear or front; or sprocket wheels 41 are respectively and coaxially fixedly arranged at both ends of the harrow tooth shaft 43. The sprocket wheels 41 at both ends of the harrow tooth shaft 43 are alternately linked to the sprocket wheels 41 of the adjacent harrow tooth shafts 43 in the front side and the rear side.

[0038] A plurality of harrow tooth frames 45 parallel to the axis of the harrow tooth shaft 43 are circumferentially and uniformly distributed on the surface of the harrow tooth shaft 43 inside the support girder 2. The harrow teeth 44 are vertically and fixedly arranged at intervals on the harrow tooth frames 45.

[0039] A steering sprocket wheel 47 is further arranged between the main sprocket wheel 31 and the adjacent sprocket wheel 41 and / or between two adjacent sprocket wheels 41.

[0040] The hollow square tube 21 is closed at both ends and has an inspection port and a sealing gasket cover plate on the outer side wall and / or upper side wall corresponding to the sprocket 41. The upper side wall of the hollow square tube 21 also has a clearance opening for the chain 42 to pass through below the main sprocket 31.

[0041] The inner walls of the two hollow square tubes 21 are respectively provided with bearing seats 24 for supporting the rake tooth shaft 43. The end of the rake tooth shaft 43 facing the sprocket 41 passes through the bearing seat 24 and extends into the hollow square tube 21.

[0042] This utility model also includes a rotary base 6 straddling above the bagasse conveying port. A feed pipe 62 is provided inside the moving coil 61 of the rotary base 6. The load-bearing bracket 1 is vertically fixed at the top of the moving coil 61. A first driving device 7 for driving the moving coil 61 to rotate is provided on one side of the rotary base 6.

[0043] A second driving device 8 is fixedly installed on the moving coil 61 or the load-bearing bracket 1, and a shaftless spiral blade 9 extending into the downward feed tube 62 is connected to the drive shaft of the second driving device 8.

[0044] Working principle and process of this utility model:

[0045] like Figure 1 , 2 As shown in Figure 3, this utility model consists of a support beam 2 formed by welding two hollow square tubes 21 and a connecting beam 22 between them, and a slag-removing roller formed by welding four rows of rake teeth 44 and a rake tooth shaft 43. Ten slag-removing rollers are then installed parallel and equidistantly between the two hollow square tubes 21 of the support beam 2 using bearing seats 24. A double-row sprocket 41 is fixed at one end of the slag-removing shaft 43, located inside one side of the hollow square tube 21. The ten slag-removing rollers are divided into two groups and driven by two reduction motors 3, with five slag-removing rollers in each group. The reduction motors 3 drive the main sprocket 31 and... The steering sprocket 47 directly drives the two middle scraping rollers via chain 42. These two scraping rollers then drive the adjacent scraping rollers via another chain 42. In this way, each geared motor 3 drives the five rollers of each set of scraping rollers via four chains 42. Two sets with the same structure drive ten scraping rollers to rotate synchronously, thereby driving the rake teeth 44 on each rake tooth shaft 43 to rotate and relay the bagasse to the discharge pipe 62 in the middle of the rotary base 6. Then, under the action of gravity, the bagasse falls onto the bagasse conveyor belt at the bottom and is transported to the boiler combustion or alcohol fermentation workshop.

[0046] During the bagasse removal process, the drive mechanism 5 and / or the first drive device 7 can be controlled by the control system according to the condition of the bagasse pile. This allows the bagasse removal mechanism on the support beam 2 to remove bagasse while simultaneously moving up and down or rotating horizontally with the support beam 2, ensuring that the rake teeth 44 continuously feed the bagasse into the feed pipe 62 for return. At the same time, the shaftless spiral blades 9 are continuously driven to rotate by the electric motor and its reducer (i.e., the second drive device 8) during bagasse removal, preventing bagasse from clogging the feed inlet or feed pipe 62.

[0047] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
