Description

Technical field:

[0001] The utility model relates to the technical field of belt unloading equipment, in particular to a ring bucket feeder. Background technology:

[0002] Calcium carbide furnace is the main equipment for producing calcium carbide. In the calcium carbide furnace, due to the high temperature generated by the electric arc, the charge (quicklime and carbon-containing raw materials) is melted and reacted to form calcium carbide. During the processing, the mixed material is added into the electric furnace through the inlet or pipeline at the top of the electric furnace, and heated to about 2000℃ in an open or closed electric furnace to react and form calcium carbide.

[0003] The existing patent publication number: CN219083754U discloses a ring bucket feeder for feeding calcium carbide furnace production, including: a driving device, the driving device is used to drive the ring bucket feeder body to move along the track body; a walking wheel mechanism, the walking wheel mechanism is installed below the ring bucket feeder body, and the feeding hopper, the feeding hopper is installed on the ring bucket feeder body at an equal distance; a door opening mechanism, the door opening mechanism is installed at the bottom of each feeding hopper, and a door closing mechanism is arranged below each door opening mechanism, and the door closing mechanism is installed above the calcium carbide furnace; a dust cover, a dust cover is installed above each feeding hopper. The ring bucket feeder feeds by counterclockwise rotation, which solves the problem that the existing use of multiple belts to alternately transport the mixture of semi-coke and lime for multiple times, and the materials are prone to position deviation during the material dropping process, resulting in uneven material ratio, and the multiple conveying belt equipment structures are numerous and complex, which increases the maintenance work intensity of on-site personnel.

[0004] The following technical defects were found in the actual use of this solution:

[0005] 1. Since the discharge ports of the 54 feeding hoppers are located higher than the entrance of the silo and the entrance diameter of the silo is limited, the feeding hoppers are in the process of moving during the feeding process. When the feeding hoppers are discharged, some materials fall around the entrance of the silo, which is not convenient for cleaning and causes waste of materials.

[0006] 2. The ring bucket feeder rotates along the track body through its body. During the rotation, the feeding hopper is opened by the door opening mechanism, so that the material in the feeding hopper falls into the silo and is closed by closing the door. During use, usually four feeding hoppers corresponding to one silo are arranged under the ring bucket feeder. Due to the limited diameter of the silo entrance and the limited time for the feeding hopper to pass through the silo, after the ring bucket feeder body moves along the track body for one circle to feed, within this time range (that is, after the material in the feeding hopper moves from the first silo to the last silo), if the material in the feeding hopper does not fall into the silo completely, when the feeding hopper is refilled again, there is a possibility that the material overflows from the top of the feeding hopper and falls into the track, which will cause the equipment to fail to operate normally and malfunction.

[0007] Therefore, based on the technical defects of this solution, this application proposes a local improvement plan. Utility model content:

[0034] Since this scheme is a partial improvement scheme based on the technical scheme of a ring bucket feeder for charging calcium carbide furnace production disclosed in the existing patent publication number: CN219083754U; therefore, the working principle of the existing equipment will not be elaborated here, and the working principle of the above-mentioned mechanism can be explained by referring to the contents of the comparative documents.

[0035] The following are partial improvements made to the existing technical solutions to solve the existing technical defects.

[0036] In order to prevent materials from spilling around the silo opening during the feeding process, eight chutes 7 are arranged under the existing track 1. The bottom outlet of each chute 7 is inserted into the top of the silo entrance correspondingly, and the chute is used to guide the material to prevent it from spilling around the silo opening.

[0037] Currently, only 8 silos are actually used. Taking 8 silos as an example, the adjacent two sides of the feeding area 8 are the first silo 10.1 and the eighth silo 10.2 respectively; all the feeding hoppers 4 can only move counterclockwise during the movement along the track 1, and the eight silos are fed successively. In order to avoid some materials remaining in the feeding hopper 4 before feeding in the feeding area 8, the solution is as follows:

[0038] According to the existing equipment, the lifting mechanism 5.3 located above the eighth silo 10.2 is completely replaced with a connecting track 9. The connecting track 9 is in a "trapezoidal" structure. The middle of the upper surface of the connecting track 9 is horizontal, and the upper surfaces of both ends are symmetrically inclined downward. The connecting track 9 is fixedly installed on the outer side of the track welding rail 1.1, so that the rotating wheels 5.13 on the four door opener mechanisms 5 rotate and fit on the upper surface of the connecting track 9. When the rotating wheels 5.13 move to the horizontal upper surface of the connecting track 9, the side panels 5.12 will rotate, so that the corresponding The discharge ports of the feeding hopper 4 are all opened. Since the horizontal upper surface of the connecting track 9 is longer, the opening time of the lower bin door 5.15 is extended, so that all the materials in the feeding hopper 4 are forced to fall into the eighth bin 10.2. Finally, the lower bin door 5.15 is closed by the door closer mechanism 6. At the same time, the reset mechanism 5.2, under the action of the tension spring 5.22, causes the hook 5.14 to lock the lower bin door 5.15 again; thereby, when the feeding hopper 4 is refilling in the refilling area 8, the materials will not overflow from the top of the feeding hopper and fall into the track.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
