Description

Technical Field

[0001] The invention relates to the technical field of bucket-lifting and conveying of materials, and in particular to a bucket-lifting and conveying system and a conveying method for spodumene materials. Background Art

[0002] Bucket elevator is a kind of conveying equipment that transports materials from low to high. Compared with conveyor belts, bucket elevator has the advantages of small space occupation and simple structure, so it is also widely used in industrial production. Generally, bucket elevator includes a casing and sprockets and chains in the casing. The sprockets are arranged up and down, and the chain is wound on the sprocket. Several buckets are fixedly installed on the chain. The buckets make a circular motion with the chain. The feed port is set at the bottom of one side of the casing. The material entering the feed port can fall into the hopper. After the hopper moves to a high place, it flips. Under the action of gravity and centrifugal force, the material in the hopper leaves the bucket elevator from the discharge port at the corresponding position on the upper part of the casing, completing the transportation of materials from low to high. However, due to the conveying principle of the bucket elevator, the material entering the feed port cannot be completely caught by the bucket, and some of the material will fall to the bottom of the casing; when the bucket runs to a high place, the material in it cannot completely enter the discharge port, and some of the material will also fall to the bottom of the casing. The residual material at the bottom of the bucket elevator will wear the bucket, hinder the movement of the bucket, and even jam the equipment.

[0003] In this regard, Chinese invention patent CN219669302U provides a device for recovering broken glass at the bottom of a bucket elevator, comprising: a sealed suction pipe, the first end of which is connected to the inside of the bucket elevator from the bottom of the side of the bucket elevator; a sealed hopper, which is connected to the second end of the sealed suction pipe; and a negative pressure generating mechanism, which is connected to the sealed hopper, for generating negative pressure inside the sealed hopper, so as to recover the broken glass at the bottom of the bucket elevator into the sealed hopper through the sealed suction pipe. In this invention patent, the negative pressure generating mechanism is used to transport the residual materials at the bottom of the bucket elevator to the feed port of the bucket elevator for secondary transport, which can prevent the bucket elevator from accumulating too much materials at the bottom of the casing during movement and causing adverse effects on the normal operation of the equipment. However, during its operation, materials will always fall into the bottom of the casing. After the material transportation is completed, there will always be materials remaining at the bottom of the casing, which will affect the secondary use of the equipment. In addition, some materials will be attached to the bottom of the casing to form crusts and lumps after being retained for a long time, and this part of the residual materials is more difficult to handle.

The present invention is mainly used to transport the materials at the bottom of the bucket elevator 2 to a higher place, so that there is no material residue at the bottom of the bucket elevator 2.

[0062] Embodiment 2:

[0063] The present invention provides a method for bucket-lifting and conveying spodumene materials. Based on the above, the present invention provides a bucket-lifting and conveying system for spodumene materials. The specific steps are as follows:

[0064] Start the equipment, the material enters the interior of the bucket elevator 2 from the feed port 201 of the bucket elevator 2, is lifted to a high place by the hopper 24, and then enters the discharge port 202. In this way, the material is continuously transported to the material receiving place at a high place. During this period, the material continuously falls into the material storage bin 4 at the bottom of the bucket elevator 2. The material in the material storage bin 4 is sucked and transported to the feed port 201 by the pneumatic conveying device 3 for lifting and conveying again, so that the material amount at the bottom of the bucket elevator 2 reaches a dynamic balance;

[0065] When the material feeding is finished and no more material enters the feed port 201, the hopper 24 continues to operate to complete the conveying of the existing material in the hopper and then stops moving. At this time, some residual materials that have not been completely sucked out are still accumulated in the material storage drawer 4. The push drawer device is started, and the rodless cylinder 17 pushes the material storage drawer 4 into the first track groove 61 along the second track groove 93 through the cooperation of the push rod 19 and the push block 18, and pushes the material storage drawer 4 from the bottom of the bucket elevator 2 to the lifting platform 6, so as to achieve the following effect. Fig.11 The state shown is the initial state of the lifting platform 6 in the accommodating hole 91. When the material storage bin 4 leaves the lower part of the bucket elevator 2, the first gear 20 meshes with the second rack 7, and the first gear 20 rotates under the action of the second rack 7. The rotation of the first gear 20 drives the second gear 21 to rotate, and the first rack 221 moves downward under the action of gravity and the second gear 21, so that the material port door 22 closes the discharge hole 42 to prevent the material from leaking during the movement of the material storage bin 4.

[0066] The material storage drawer 4 moves to the lifting platform 6, the first lifting mechanism and the second lifting mechanism move synchronously, the first motor 5 and the second motor 8 rotate at the same speed, and the lifting platform 6 is lifted synchronously to lift the material storage drawer 4 to a high position, so as to achieve Fig.12 Then the second motor 8 stops running and is locked, the first motor 5 continues running, the first support frame 12 continues to rise while the second support frame 13 stops moving, the slider 122 on the first support frame 12 slides along the strip hole 62 at the bottom of the lifting platform 6, so that the lifting platform 6 rotates around the hinge seat 131, and the material storage bin 4 rotates to a certain angle, reaching Fig.13 , Fig.14 The unloading state shown in FIG. 1 is as follows: at this time, the state of the lifting platform 6 and the material storage drawer 4 is as follows: Fig.14 The cylinder 23 drives the discharge door 43 to open, and the residual materials in the material storage bin 4 are poured into the material receiving area, so that the residual materials at the bottom of the bucket elevator 2 are transported to a higher place. The first track groove 61 is a dovetail groove structure, so the material storage bin 4 will not slide off the lifting platform 6 when the lifting platform is tilted.

[0067] After the material storage bin 4 is unloaded, the cylinder 23 controls the unloading door 43 to close, the first motor 5 drives the first support frame 12 to descend to the same height as the second support frame 13, and then the first motor 5 and the second motor 8 move synchronously to make the lifting platform 6 descend into the receiving hole 91. At this time, the two ends of the push rod 19 fall between the two push blocks 18 on the corresponding sides, and the rodless cylinder 17 retracts to push the material storage bin 4 along the first track groove 61 and the second track groove 93 into the bottom of the bucket elevator 2. After the material storage bin 4 enters the bottom of the bucket elevator 2, the second rack 7 meshes with the first gear 20, the rotation of the first gear 20 drives the rotation of the second gear 21, and the rotation of the second gear 21 drives the first rack 221 to rise to open the material port door 22, so that the discharge hole 42 is reconnected with the pneumatic conveying device 3.

[0068] 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 principle of the present invention should be included in the protection scope of the present invention.
