Description

Technical Field

[0001] This utility model relates to the field of wheel stacker reclaimer technology, and in particular to a self-cleaning system for a sulfur bucket wheel stacker reclaimer. Background Technology

[0002] Sulfur is a commonly used chemical raw material with a wide range of applications, such as the manufacture of sulfuric acid, the production of sulfur dyes, and the production of rubber products. The consumption of sulfur is enormous, and the efficiency of sulfur loading, storage, and transportation has become an urgent problem to be solved.

[0003] The bucket wheel stacker-reclaimer is a high-efficiency loading and unloading machine used in large dry bulk cargo yards, capable of both stacking and reclaiming materials. It consists of a belt conveyor arm that can tilt and swing horizontally, along with its front bucket wheel, frame, and running mechanism. The belt can run in both directions. It is a rail-mounted loading and unloading machine that uses the bucket wheel for continuous material reclamation and the onboard belt conveyor for continuous material stacking. During material reclamation, the bucket wheel picks up the material and sends it out through the conveyor arm. During material stacking, the goods brought in by the main conveyor are thrown into the yard through the conveyor arm. It has become a key device for solving the problems of sulfur storage and transportation.

[0004] Existing bucket wheel stacker-reclaimers lack a cleaning system, resulting in arduous cleaning work after the bucket wheel stacker-reclaimer has finished its work. Furthermore, the large size of the bucket wheel stacker-reclaimer leads to low cleaning efficiency and incomplete cleaning. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a self-cleaning system for a sulfur bucket wheel stacker-reclaimer, which can achieve comprehensive cleaning of the inside and outside of the bucket.

[0006] The technical solution adopted by this utility model is as follows: A self-cleaning system for a sulfur bucket wheel stacker-reclaimer includes a support arm, a drive reduction motor is fixedly installed at the front end of the support arm, the drive reduction motor is connected to a rotating shaft through a coupling, the coupling is a chain coupling, the rotating shaft is rotatably connected to the support arm through a first bearing seat, and a hopper frame is fixedly connected to the end of the rotating shaft, with multiple hoppers evenly distributed on the hopper frame.

[0007] Furthermore, two parallel double-slider guide rails are arranged on the support arm, with two sliders slidably arranged on each double-slider guide rail. A base plate is fixed on the slider, and a water tank is set on the base plate. A water inlet is set on the upper side of the water tank, and a water pump is connected to the side of the water tank. The outlet of the water pump is connected to the spray pipe.

[0008] Furthermore, a solenoid valve is installed between the water pump and the water tank.

[0009] Furthermore, multiple rows of branch pipes are evenly distributed around the outer circumference of the nozzle, and each row of branch pipes has multiple branch pipes arranged axially in parallel, with a nozzle installed at the end of each branch pipe.

[0010] Furthermore, the nozzle is rotatably connected to the base plate via a second bearing seat. A driven gear is fixedly installed on the nozzle, which meshes with the driving gear. The driving gear is fixedly connected to the output shaft of the servo geared motor, which is fixedly installed on the base plate.

[0011] Furthermore, the upper side of the support arm is bolted to the drive module, the end of the drive module is equipped with a moving motor, the upper side of the drive module is slidably equipped with a drive slide plate, and the drive slide plate is fixedly connected to the lower side of the base plate.

[0012] Furthermore, the water pump outlet is connected to the connecting sleeve, and the end of the connecting sleeve is bolted to the end cap. The end cap is fitted onto the end of the nozzle, and the end cap and the end of the nozzle are dynamically sealed together.

[0013] Furthermore, the inner ring of the end cap has multiple annular grooves arranged side by side.

[0014] The advantages of this new design are: the drive module moves the nozzle closer to or away from the hopper without interfering with the normal operation of the hopper; the servo reducer motor drives the nozzle to rotate, which in turn drives the branch pipe to rotate, achieving thorough cleaning of the hopper.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-8 As shown, this utility model provides a self-cleaning system for a sulfur bucket wheel stacker-reclaimer, including a support arm 1. A drive reduction motor 11 is fixedly installed at the front end of the support arm 1. The drive reduction motor 11 is connected to a rotating shaft 112 through a coupling 114. The coupling 114 is a chain coupling. The rotating shaft 112 is rotatably connected to the support arm 1 through a first bearing seat 113. A hopper frame 12 is fixedly connected to the end of the rotating shaft 112. Multiple hoppers are evenly distributed on the hopper frame 12. A receiving hopper for receiving materials is set in the middle of the hopper frame 12. The receiving hopper works with a conveyor belt to realize material collection and stacking. The receiving hopper and the conveyor belt are existing technologies and will not be described in detail here.

[0028] See Figures 1-4 Two double slider guide rails 13 are arranged in parallel on the support arm 1. Two sliders 131 are slidably arranged on each double slider guide rail 13. A base plate 15 is fixed on the slider 131. A water tank 2 is arranged on the base plate 15. A water inlet 21 is arranged on the upper side of the water tank 2. A water pump 22 is connected to the side of the water tank 2. The outlet of the water pump 22 is connected to the spray pipe 23. The water pump 22 pumps the water in the water tank 2 to the spray pipe 23 and sprays the water onto the hopper through the spray pipe 23 to achieve the rinsing and cleaning of the hopper.

[0029] A solenoid valve is installed between the water pump 22 and the water tank 2. The solenoid valve controls the opening and closing of the water pump 22 and the water tank 2 to prevent water leakage in the water tank 2 when it is not cleaned. The solenoid valve is existing technology and will not be described in detail here.

[0030] Multiple rows of branch pipes 233 are evenly distributed around the outer circumference of the nozzle 23. Each row of branch pipes 233 has multiple branch pipes 233 arranged in parallel along the axis. Each branch pipe 233 has a nozzle at its end. The arrangement of the branch pipes 233 can evenly spray water onto the hopper, increasing the spraying and rinsing area and improving the water spraying effect. The nozzles also improve the flushing effect and cleaning effect.

[0031] See Figure 4 The nozzle 23 is rotatably connected to the base plate 15 via the second bearing seat 232. A driven gear 242 is fixedly mounted on the nozzle 23, and the driven gear 242 meshes with the driving gear 241. The driving gear 241 is fixedly connected to the output shaft of the servo reduction motor 24, which is fixedly mounted on the base plate 15. The servo reduction motor 24 drives the nozzle 23 to rotate, which in turn drives the branch pipe 233 to rotate, thus cleaning the inside and outside of the hopper.

[0032] See Figure 5 and Figure 6 The upper side of the support arm 1 is bolted to the drive module 14. The end of the drive module 14 is equipped with a moving motor 141. The drive slide plate 142 is slidably mounted on the upper side of the drive module 14. The drive slide plate 142 is fixedly connected to the lower side of the base plate 15. The drive slide plate 142 drives the base plate 15 to move on the double slider guide rail 13. The movement of the base plate 15 drives the nozzle 23 to move away from or closer to the hopper.

[0033] See Figure 7 and Figure 8 The outlet of the water pump 22 is connected to the connecting sleeve 231. The end of the connecting sleeve 231 is bolted to the end cap 2311, which is fitted onto the end of the nozzle 23, forming a dynamic seal between the end cap 2311 and the end of the nozzle 23. The connecting sleeve 231 and the end cap 2311 achieve a rotational seal connection between the nozzle 23 and the water pump 22, facilitating the rotation of the nozzle 23.

[0034] The inner ring of the end cap 2311 has multiple annular grooves 2312 arranged in parallel. Dynamic sealing connection is achieved through the multiple parallel grooves 2312. Other dynamic sealing connections can also be used in this invention, which will not be described in detail here.

[0035] Working principle: When cleaning is not required, the drive module 14 moves the base plate 15 away from the hopper frame 12, so that the base plate 15 and the nozzle 23 do not affect the rotation of the hopper frame 12.

[0036] When the hopper needs cleaning, the drive module 14 drives the base plate 15 and the nozzle 23 to approach the hopper support frame 12. At this time, the hopper support frame 12 is not rotating. At this time, the solenoid valve is opened, the water pump 22 works, and the water pump 22 drives water to spray out at high speed from the end of the branch pipe 233 of the nozzle 23.

[0037] At the same time, the servo reduction motor 24 drives the drive gear 241 to rotate, the drive gear 241 drives the driven gear 242 and the nozzle 23 to rotate, and the nozzle 23 drives multiple branch pipes 233 to rotate, thereby achieving a comprehensive flushing of the inside of the hopper and a cleaning and rinsing of the outside of the adjacent hopper.

[0038] After cleaning one hopper, rotate the hopper and repeat the cleaning steps for the next hopper until all hoppers have been cleaned.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
