Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, and in particular to a feeding structure of a bucket elevator. Background Art

[0002] In the prior art, when raw materials are fed into the bucket elevator, they are fed at the charging port, and after the raw materials enter the silo, they enter the bucket elevator through the vibrating feeder. During the production process, the discharge is unstable due to the differences in humidity and particle size of the raw materials, so the vibration amplitude needs to be adjusted frequently to meet the production needs. The amplitude adjustment takes a long time and is prone to being adjusted too large or too small. Since the feeder needs to have sufficient shaking margin during operation, the feeder's inlet and outlet can only be wrapped with soft connections. If the wrapping is not tight, the material will leak and spray dust, affecting the on-site environment and putting great pressure on environmental protection. If the wrapping is too tight, the soft connection is easy to tear, which will still cause leakage and dust spraying. Moreover, after each adjustment of the amplitude, the tightness of the soft connection will change and need to be replaced, which puts too much pressure on maintenance. 6S refers to the six items of sorting (SE I RI), reorganizing (SE I TON), cleaning (SE I SO), cleaning (SE IKETSU), quality (SH I TSUKE), and safety (SECURI TY). Because they all start with "S", they are referred to as 6S.

[0003] After searching, the applicant found that the Chinese patent document with publication number CN102564114A disclosed a rotary kiln unloading chute device on July 11, 2012, which includes a chute pipe and a tail cover. The chute pipe is obliquely inserted into the cooling machine barrel through the tail cover. The lower end of the tail cover is equipped with an ash outlet. The chute pipe is connected to the feed shell, and the feed shell is connected to the wheel group. The wheel group is supported on the track; a pneumatic gate valve is installed between the emergency discharge port and the feed shell. An emergency cooling water pipeline is installed outside the emergency discharge port. Both sides of the feed shell are connected to the wheel group.

[0004] The device cannot control the flow of raw materials, which can easily cause blockage, leakage and dust spraying. Utility Model Content

[0031] The following is a further detailed explanation of the specific implementation methods of the utility model through the description of the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the utility model and facilitating its implementation.

[0032] Figure 1 The bucket elevator feeding structure shown comprises a chute 1, both ends of which are respectively connected to a silo 2 and a bucket elevator 3; a flow control structure and a dredging structure are respectively provided on the chute 1.

[0033] The chute 1 effectively eliminates the problem of material leakage and dust spraying, can ensure the sanitation of the production site, and is convenient for 6S management; and the chute 1 replaces the vibrating feeder, effectively reducing the production cost; at the same time, the chute 1 is integrally connected with the silo 2 and the bucket elevator 3, replacing the soft connection, and there is no need to replace and repair the worn soft connection, which effectively saves maintenance costs and reduces the labor intensity of the staff;

[0034] The flow control structure can control the size of the pipe diameter passing through the chute 1; the staff can reasonably adjust the size of the pipe diameter passing through the material according to the humidity and particle size of the material falling from the silo 2, thereby realizing accurate control of the material flow and stabilizing the material discharge speed;

[0035] The dredging structure can effectively clear material blockages and ensure the normal production.

[0036] The flow control structure includes a first gate valve 4, which is connected to the slide pipe 1. The first gate valve 4 can control the size of the pipe diameter passing through the slide pipe 1; the staff can reasonably adjust the size of the pipe diameter of the material according to the humidity and particle size of the material falling from the silo 2, thereby realizing accurate control of the material flow and stabilizing the material discharge speed.

[0037] The unblocking structure includes an air hammer 5, which is connected to the outer wall of the chute 1. The air hammer 5 can quickly and repeatedly hammer the side wall of the chute 1, thereby vibrating the blocked part of the chute 1 and causing the blocked materials to disperse and fall, effectively unblocking the material blockage and ensuring the normal production.

[0038] The air hammer 5 is arranged on the side of the first gate valve 4 close to the silo 2. The silo 2 is a funnel-shaped structure. The material enters the chute 1 from the silo 2. When too much material is added or the material humidity is high, it is easy to cause blockage at the connection between the silo 2 and the chute 1; the air hammer 5 is installed between the silo 2 and the first gate valve 4; when the material falls from the silo 2 into the chute 1 and causes blockage, the air hammer 5 is started to hammer the side wall of the chute 1, so that the chute 1 vibrates and the blocked material is dispersed and falls.

[0039] The slide pipe 1 is provided with a second gate valve 6. The second gate valve 6 is provided with a second gate plate 604, which is placed inside the slide pipe 1 and can control the size of the pipe diameter passing inside the slide pipe 1; when the second gate valve 6 fails in the device, it can stop the slide pipe 1 from feeding materials to the bucket elevator 3.

[0040] The second gate valve 6 is arranged on the side of the first gate valve 4 close to the bucket elevator 3. When the equipment is operating normally, the second gate valve 6 is always open; when the moisture and particle size of the material change, resulting in faster material discharge, abnormal equipment, and larger current, the second gate valve 6 directly closes the chute 1 and no longer delivers material to the bucket elevator 3, effectively avoiding equipment overload.

[0041] The first gate valve 4 includes a first mounting frame 402, and a handle 401 is connected to the first mounting frame 402; the handle 401 is connected to a first gate plate 403. A first gate plate mounting hole is provided on the side wall of the slide pipe 1, and the staff pushes the handle 401 to push the first gate plate 403 from the first gate plate mounting hole into the interior of the slide pipe 1, thereby reducing the flow rate of the material; the staff pulls the handle 401 to pull the first gate plate 403 out of the first gate plate mounting hole from the interior of the slide pipe 1, thereby increasing the flow rate of the material; the first gate valve 4 has a low manufacturing cost, a simple structure, convenient operation, is not easy to be damaged, and has a long service life.

[0042] The second gate valve 6 includes a second mounting frame 602, to which a cylinder is connected; a driving rod 603 is provided on the cylinder, to which a second gate plate 604 is connected. A second gate plate mounting hole is provided on the side wall of the slide pipe 1; when the cylinder is started, the driving rod 603 pushes the second gate plate 604 from the second gate plate mounting hole into the interior of the slide pipe 1 to cut off the transportation of materials; when the cylinder is started again, the driving rod 603 pulls the second gate plate 604 out of the second gate plate mounting hole to continue the transportation of materials; the pneumatic gate valve is selected, which has fast response speed, low cost, simple structure and is not easy to damage.

[0043] The first mounting frame 402 and the second mounting frame 602 are both mounted on the outer wall of the slide pipe 1; the first gate plate 403 and the second gate plate 604 are both placed inside the slide pipe 1. The first mounting frame 402 and the second mounting frame 602 are both square frames, which can guide and limit the movement of the first gate plate 403 and the second gate plate 604; the first gate plate 403 enters the inside of the slide pipe 1 to control the flow of the material in the slide pipe 1; the second gate plate 604 enters the inside of the slide pipe 1 to cut off the transportation of the material in the slide pipe 1.

[0044] The silo 2 is a conical structure with openings at both ends; the chute 1 and the bucket elevator 3 are arranged at an angle. The silo 2 is a conical structure, which facilitates the entry of materials into the chute 1; the chute 1 is arranged at an angle, and the materials slide into the bucket elevator 3 along the chute 1 under the influence of gravity.

[0045] The specific working process of the utility model is as follows:

[0046] The material enters the inclined chute 1 from the silo 2 and slides into the bucket elevator 3 along the chute 1;

[0047] According to the humidity and particle size of the material dropped from the silo 2, the staff uses the handle 401 to push the first gate plate 403 to reasonably adjust the diameter of the pipe through which the material passes, thereby achieving accurate control of the material flow rate and stabilizing the material discharge speed;

[0048] When the equipment is operating normally, the second gate 604 is always open; when the material moisture and particle size change, resulting in faster material feeding, abnormal equipment, and larger current, the second gate 604 directly closes the slide pipe 1 and no longer delivers material to the bucket elevator to avoid equipment overload;

[0049] When materials fall from the silo 2 into the chute 1 and cause blockage, the air hammer 5 is started to hammer the side wall of the chute 1, thereby causing the chute 1 to vibrate and the blocked materials to disperse and fall.

[0050] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
