Description

Technical Field

[0001] The utility model relates to the technical field of lime hoppers, in particular to an anti-blocking lime hopper. Background Technique

[0002] Lime is a commonly used building material and industrial raw material. It is easy to absorb moisture and undergo chemical reactions in a humid environment, forming hard lumps, which can cause blockages in hoppers and conveying systems, affecting production efficiency. An anti-blocking lime hopper is a specially designed device for storing and conveying lime (calcium oxide), aiming to prevent lime from caking or blocking in the hopper.

[0003] Currently, the existing lime hoppers only use vibrators to prevent blockages, which has limitations. It may not be able to comprehensively and effectively handle the complex blockage situations of lime in the hopper. When lime cakes or has a large density, it is not sufficient to completely clear the blockage, thus affecting the smooth conveying of lime and production efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to solve the drawback that the existing technology has limitations in preventing blockages of lime hoppers by using vibrators, resulting in insufficient ability to completely clear blockages when lime cakes or has a large density, thus affecting the smooth conveying of lime and production efficiency, and to propose an anti-blocking lime hopper.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An anti-blocking lime hopper, comprising:

[0007] A hopper body, on one side of the bottom of the hopper body, a vibrator is fixedly arranged;

[0008] A lifting assembly, which is arranged on the hopper body and is used to drive the stirring mechanism to move up and down;

[0009] A stirring mechanism, which is arranged on the lifting assembly and is used to stir and dredge the blocked lime in the hopper body.

[0010] In a possible design, the lifting assembly includes four connecting seats fixedly arranged in a rectangular shape outside the hopper body. At the top of the four connecting seats, electric push rods are fixedly arranged, and the output ends of the four electric push rods are fixedly provided with the same fixing frame.

[0011] In a possible design, the stirring mechanism includes a rotating rod rotatably arranged at the bottom of the fixing frame. A spiral stirring blade is fixedly arranged outside the bottom end of the rotating rod. A motor is fixedly arranged at the top of the fixing frame, and one end of the output shaft of the motor rotatably penetrates through the top of the fixing frame and is fixedly connected to the rotating rod.

[0012] In a possible design, springs are fixedly arranged at the bottoms of the four connecting seats, and the bottoms of the four springs are fixedly provided with the same support frame.

[0013] In a possible design, four threaded rods are threadedly connected to the bottom of the support frame in a rectangular shape. The bottoms of the four threaded rods are fixedly provided with support pads, and locking nuts are threadedly connected to the exteriors of the four threaded rods.

[0014] In a possible design, anti-slip pads are fixedly arranged at the bottoms of the four support pads.

[0015] In this application, when starting to use, first place the anti-blocking lime hopper at a predetermined working position. When the ground is in an uneven state, rotate the support pads at the bottom of the support frame at the uneven position. When the support pads rotate, the threaded rods thereon rotate synchronously, causing the threaded rods to extend out from the bottom of the support frame until the support pads are in contact with the ground. Subsequently, rotate the support pads at different positions in sequence according to the ground conditions so that the four support pads are all in contact with the ground. Then, rotate the locking nuts at each position in sequence so that the locking nuts are in contact with the bottom of the support frame to complete the locking of the positions of the threaded rods, thereby adjusting the overall levelness of the anti-blocking lime hopper according to the ground conditions to make the hopper reach a horizontal and stable state. The anti-slip pads at the bottoms of the four support pads can increase the close contact with the ground and increase the friction between the whole and the ground, strengthening the overall stability of the device;

[0016] Subsequently, connect the whole device to the power supply and check whether the power connections of the electric push rods, motors, and vibrators are firm, and there is no short circuit or open circuit phenomenon. Then, confirm that there is no foreign object jamming in the spiral stirring blades in the stirring mechanism and the rotating rod rotates flexibly. Then, check whether the springs are in a normal compressed state and whether the connection between the connecting seat and the hopper body is firm. After all inspections are completed, convey the lime to the feed port on the upper cover through the conveying mechanism and then enter the hopper body through the feed port. At this time, start the vibrator to perform preliminary vibration on the hopper body to prevent or reduce the accumulation and blockage of lime in the hopper. When the lime shows accumulation and blockage phenomena in the hopper, first start the motor. The output shaft of the motor drives the rotating rod to rotate, and the spiral stirring blades thereon rotate synchronously while the rotating rod rotates. Subsequently, start the electric push rods. The output ends of the four electric push rods work synchronously and contract. While the output ends of the electric push rods contract synchronously, they drive the fixed frames thereon and the stirring mechanism above to slowly descend. During the descent of the stirring mechanism, the spiral stirring blades thereon strongly stir and dredge the blocked lime that may exist in the hopper. At the same time, according to the actual situation, the lifting stroke and number of times of the electric push rods can be adjusted to make the stirring mechanism perform reciprocating up and down movements in the hopper while keeping the spiral stirring blades rotating continuously to ensure the uniform distribution of lime in the hopper and prevent blockage;

[0017] When the lime conveying is completed and it is confirmed that the lime in the hopper flows smoothly without blockage, first turn off the motor to stop the rotation of the spiral stirring blade, then lift the stirring mechanism to the initial position through the electric push rod to avoid direct contact with the bottom of the hopper in the non-working state, and finally turn off the vibrator and all power supplies, and clean the working environment around the hopper to ensure that the equipment is clean and free of foreign objects.

[0018] The utility model has the following beneficial effects:

[0019] In the utility model, through the setting of the lifting assembly, the output ends of the four electric push rods work synchronously and contract. While the output ends of the electric push rods contract synchronously, the fixed frame on them and the stirring mechanism above are driven to slowly descend. By using the synchronous contraction of the electric push rods, the stirring mechanism is driven to lift and lower flexibly, effectively dealing with the problems of lime accumulation and blockage.

[0020] In the utility model, through the setting of the stirring mechanism, the output shaft of the motor drives the rotating rod to rotate, and while the rotating rod rotates, the spiral stirring blade on it rotates synchronously. During the process of the electric push rod driving the stirring mechanism to descend, the spiral stirring blade on it strongly stirs and dredges the blocked lime that may exist in the hopper.

[0021] Through the combined setting of the lifting assembly and the stirring mechanism in the utility model, the problems of lime accumulation and blockage in the hopper are effectively solved, the uniform distribution and smooth conveying of lime are realized, and the operation efficiency and stability of the equipment are significantly improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Embodiment

[0028] Referring to Figures 1-4 , a hopper includes:

[0029] A hopper body 1 for storing and conveying lime. On one side of the hopper body 1, a vibrator 8 (model number can be: ZFB / LZF-3) is fixedly arranged. The vibrator 8 is firmly installed on the outside of the hopper body 1 by bolts or other fastening methods. When the vibrator 8 is started, it can perform preliminary vibration on the hopper body 1, thereby preventing or reducing the accumulation and blockage of lime in the hopper. The top of the hopper body 1 is detachably provided with an upper cover. The top of the upper cover is fixedly communicated with a feed inlet, and an opening for the up and down movement of a rotating rod 5 is provided on the top of the upper cover.

[0030] In order to drive the stirring mechanism to move up and down, a lifting assembly is arranged on the hopper body 1. The lifting assembly specifically includes four connecting seats 2 arranged in a rectangle. These connecting seats 2 are fixed to the outside of the hopper body 1 by welding or other fastening methods. On the top of each connecting seat 2, an electric push rod 3 is fixedly installed. The output ends of the four electric push rods 3 are commonly connected and fixed to a fixed frame 4. When the four electric push rods 3 work simultaneously, they can contract or extend synchronously, thereby driving the fixed frame 4 and the stirring mechanism thereon to move up and down.

[0031] The stirring mechanism is installed on the fixed frame 4 of the lifting assembly. The stirring mechanism mainly includes a rotating rod 5 rotatably arranged at the bottom of the fixed frame 4. A spiral stirring blade 6 is fixedly arranged on the outer part of the bottom end of the rotating rod 5. The design of the spiral stirring blade 6 can generate a large stirring force when stirring lime, which helps to dredge the blocked lime. In addition, a motor 7 is fixedly arranged on the top of the fixed frame 4. The output shaft of the motor 7 passes through the top of the fixed frame 4 through components such as bearings and is fixedly connected to the rotating rod 5, thereby driving the rotating rod 5 and the spiral stirring blade 6 to rotate. The spiral stirring blade 6 will not touch the upper cover when rising to the highest position and will not touch the inner wall of the hopper body 1 when descending to the lowest position.

[0032] This application can be used in the technical field of anti-blocking lime hoppers, and can also be used in other fields applicable to this application. Embodiment

[0033] On the basis of the first embodiment, the second embodiment further includes: an anti-clogging lime hopper, which is applied to the technical field of anti-clogging lime hoppers. In order to further improve the stability of the entire device, springs 9 are fixedly arranged at the bottoms of the four connecting seats 2, and the bottoms of the springs 9 are jointly connected to a support frame 10. The arrangement of the springs 9 can, to a certain extent, alleviate the vibrations generated during the operation of the device and improve the durability of the equipment.

[0034] Four threaded holes are opened at the bottom of the support frame 10, and the four threaded holes are respectively threadedly connected to the four threaded rods 11. A support pad 12 is fixedly arranged at the bottom of the threaded rod 11. When the ground is in an uneven state, rotate the support pad 12 at the bottom of the support frame 10 at the uneven position. When the support pad 12 rotates, it drives the threaded rod 11 thereon to rotate synchronously, so that the threaded rod 11 extends out from the bottom of the support frame 10 until the support pad 12 abuts against the ground. Subsequently, rotate the support pads 12 at different positions in sequence according to the ground conditions, so that the four support pads 12 all abut against the ground. In order to prevent the threaded rod 11 from loosening during use, a locking nut 13 is threadedly connected to the outside of each threaded rod 11. Rotate the locking nuts 13 at each position in sequence, so that the locking nuts 13 abut against the bottom of the support frame 10 to complete the locking of the position of the threaded rod 11, thereby adjusting the overall levelness of the anti-clogging lime hopper according to the ground conditions and making the hopper reach a horizontal and stable state.

[0035] Finally, in order to increase the friction between the support pads 12 and the ground and prevent the equipment from sliding during use, anti-slip pads 14 are fixedly arranged at the bottoms of the four support pads 12, so that the anti-slip pads at the bottoms of the four support pads increase the close contact with the ground and increase the friction between the whole and the ground, strengthening the overall stability of the device.

[0036] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric push rod 3, the motor 7, and the vibrator 8 are common knowledge, and they all belong to conventional means or well-known common sense, so they will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
