Description

Technical Field

[0001] The invention relates to the technical field of coal powder supply, in particular to a screening mechanism and a coal powder supply device. Background Art

[0002] In many industrial fields, especially in thermal power generation, steel smelting and other industries, coal powder is an important fuel or raw material. Its quality and pretreatment have a vital impact on the subsequent production process and equipment operation. The quality and processing efficiency of coal powder are directly related to the efficiency of energy utilization and the degree of environmental pollution. During the transportation and preliminary preparation stages of coal powder, coal powder is prone to agglomeration. This is mainly because the cleaning of coal powder makes it easy for coal powder particles to stick to each other into agglomerates. Agglomeration not only affects the fluidity of coal powder, but also may cause blockage of transportation equipment, increase energy consumption and maintenance costs. Some existing treatment methods often lack effective agglomeration treatment methods, resulting in a large amount of agglomerated coal powder unable to participate in subsequent process normally. For example, when transported to the drying equipment, the agglomerated coal powder may not be completely dried, affecting the drying efficiency, and then affecting the efficiency and stability of the entire production line.

[0024] Beneficial effects of the present invention:

[0025] 1. After the coal powder falls from the feed bin, it passes through the top short filter screen and multiple groups of short filter screens, and finally falls on the bottom filter screen and is transported by the conveyor. After the first motor is started, it drives the convex ring to rotate, squeezes the short filter screen to make it vibrate, increases the speed of coal powder passing through, and makes the agglomerated coal powder fall off. The agglomerated coal powder rolls down under the action of gravity, and after being filtered by the vibrating screen, the dry coal powder is shaken off until the agglomerates fall on the bottom filter screen, and are discharged by the bottom filter screen and the inclined plate for secondary processing. The gap generated by the rotation of the convex ring ensures that the agglomerates pass and are recycled, while squeezing and crushing the agglomerates to improve the screening effect. When large agglomerates cannot pass through the gap, the convex ring throws them up and cooperates with the vibrating screen to make the agglomerates gradually fall off and fall to the lower short filter screen. Repeat the steps to gradually make the coal powder on the surface of the large agglomerates fall off.

[0026] 2. When multiple groups of convex rings rotate, the shell body shakes as a whole, and the ring slides on the guide rod and the spring acts to reduce vibration, reduce the force on the supporting mechanism, ensure stable operation of the equipment, and improve the screening effect of the short filter screen.

[0027] 3. Through the intermittent discharge of coal powder, the coal powder is deposited on the short filter screen in sections, which reduces the screening pressure and improves the screening effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0042] Example 1

[0043] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , which is the first embodiment of the present invention, provides a screening mechanism, including a separation component 100, which includes a protection component 101, a screening component 102 and a vibration component 103, the protection component 101 is used to install the screening component 102 and the vibration component 103, the screening component 102 and the vibration component 103 are arranged in the same number of groups, adjacent vibration components 103 are staggered, and adjacent screening components 102 are staggered;

[0044] The assembly component 200 includes a connecting component 201 , a mounting component 202 and a buffer component 203 . The connecting component 201 and the mounting component 202 are used for installing the protective component 101 .

[0045] Specifically, the protective component 101 includes a shell 101a, four groups of protrusions 101b fixedly connected to the outside of the shell 101a, and a guide plate 101c fixedly connected to the bottom end of the shell 101a, an inclined plate 101d is arranged on the outside of the shell 101a, a bottom filter screen 101e is obliquely installed inside the shell 101a, a ventilation frame 101f is fixedly connected to the outside of the shell 101a, and a connecting pipe 101g is fixedly connected to one end of the ventilation frame 101f.

[0046] Furthermore, the screening assembly 102 includes a rotating shaft 102a rotatably connected to the inside of the housing 101a, and a short screening screen 102b fixedly connected to the outside of the rotating shaft 102a;

[0047] The rotating shaft 102a is connected to the housing 101a through a torsion spring, and the short filter screen 102b is tiltedly arranged inside the housing 101a;

[0048] The vibration assembly 103 includes a first motor 103a adapted to be mounted outside the housing 101a, an output shaft 103b fixedly connected to an output end of the first motor 103a, and a convex ring 103c fixedly connected to the outside of the output shaft 103b.

[0049] When the coal powder falling from the feed bin 401a lands on the surface of the top short filter screen 102b, the refined coal powder will continue to fall through the short filter screen 102b, continuously pass through multiple groups of short filter screens 102b, and finally fall on the conveyor 600 through the bottom filter screen 101e, and the coal powder is transported by the conveyor 600.

[0050] Start the first motor 103a, and the operation of the first motor 103a will drive the convex ring 103c fixed on the outside of the output shaft 103b to rotate. When the convex ring 103c rotates toward the short filter screen 102b, the convex ring 103c will squeeze the short filter screen 102b, prompting the short filter screen 102b to rotate around the rotating shaft 102a, and drive the torsion spring of the rotating shaft 102a to deform the shell 101a. When the convex ring 103c rotates toward the back of the short filter screen 102b, the short filter screen 102b is reset under the elasticity of the torsion spring to achieve a single vibration. Due to the continuous rotation of the convex ring 103c, the short filter screen 102b will be driven to vibrate continuously. The vibrating short filter screen 102b can not only increase the speed of coal powder passing through the short filter screen 102b, but also can throw and vibrate the agglomerated coal powder, prompting the agglomeration to fall off, and gradually fall off the coal powder on the surface of the agglomeration, further improving the screening effect of the coal powder.

[0051] The agglomerated coal powder will continue to roll down under the force of gravity, and then pass through multiple rounds of vibrating short filter screen 102b to ensure that the dry coal powder on the outer surface of the agglomerate is shaken off, until the agglomerate falls on the surface of the bottom filter screen 101e, and is discharged under the guidance of the bottom filter screen 101e and the inclined plate 101d, which is convenient for secondary processing.

[0052] The rotating convex ring 103c can not only drive the short filter screen 102b to vibrate, but also ensure that a gap is formed between the convex ring 103c and the short filter screen 102b, so that the agglomerates can pass smoothly and be finally recovered. When the agglomerates are in the gap between the convex ring 103c and the short filter screen 102b, the rotating convex ring 103c can squeeze the agglomerates to break the agglomerates, thereby improving the screening effect of the coal powder. When the larger agglomerates cannot pass through the gap between the convex ring 103c and the short filter screen 102b, the rotating convex ring 103c will contact and throw up the agglomerates, and cooperate with the vibrating short filter screen 102b to throw away the large agglomerates, so that they fall to the surface of the short filter screen 102b in the lower layer, and repeat the above steps to achieve the gradual shedding of the coal powder on the outer surface of the large agglomerates.

[0053] In summary, after the coal powder falls from the feed bin 401a, it passes through the top short filter screen 102b and multiple groups of short filter screens 102b, and finally falls on the bottom filter screen 101e and is transported by the conveyor 600. After the first motor 103a is started, it drives the convex ring 103c to rotate, squeezes the short filter screen 102b to make it vibrate around the rotating shaft 102a, increases the speed of coal powder passing through, and makes the agglomerated coal powder fall off. The agglomerated coal powder rolls down under the action of gravity, and after being filtered by the vibrating screen, the dry coal powder is shaken off until the agglomerates fall on the bottom filter screen 101e, and are discharged by the bottom filter screen 101e and the inclined plate 101d for secondary processing. The gap generated by the rotation of the convex ring 103c ensures that the agglomerates pass through and are recovered, while squeezing and crushing the agglomerates to improve the screening effect. When large agglomerates cannot pass through the gap, the convex ring 103c throws them up and cooperates with the short filter screen 102b to gradually fall off the agglomerates and drop them to the lower short filter screen 102b. The steps are repeated to gradually fall off the coal powder on the surface of the large agglomerates.

[0054] When the multiple groups of convex rings 103c rotate, the shell 101a shakes as a whole, and the sliding of the ring 201b on the guide rod 203a and the action of the spring 203b reduce vibration, reduce the force on the support mechanism 300, ensure stable operation of the equipment, and improve the screening effect of the short filter screen 102b.

[0055] The intermittent discharge of coal powder allows the coal powder to be deposited on the short filter screen 102b in sections, thereby reducing the screening pressure and improving the screening effect.

[0056] Example 2

[0057] Reference Figure 1 to Figure 7 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a connecting assembly 201, including a connecting plate 201a, a ring 201b fixedly connected to one end of the connecting plate 201a, and side plates 201c fixedly connected to the upper and lower sides of the connecting plate 201a. The two sets of side plates 201c and one end of the connecting plate 201a are fixedly connected to the protrusion 101b.

[0058] Specifically, the mounting assembly 202 includes a first mounting frame 202a and a second mounting frame 202b;

[0059] The buffer assembly 203 includes a guide rod 203a fixedly connected to the first mounting frame 202a and the second mounting frame 202b, and two groups of springs 203b sleeved on the outside of the guide rod 203a;

[0060] The collar 201b is sleeved on the outside of the guide rod 203a, and the collar 201b is located between the two groups of springs 203b.

[0061] When the multiple groups of convex rings 103c are in a rotating state, the eccentric action of the convex rings 103c will cause the shell 101a to shake as a whole. At this time, the sleeve ring 201b slides on the outside of the guide rod 203a, and the interaction of the two groups of springs 203b is used to reduce vibration, thereby reducing the force of the overall shaking of the shell 101a on the support mechanism 300, ensuring that the equipment can work stably and continuously. At the same time, the shaking shell 101a cooperates with the vibration, and the short filter screen 102b further improves the screening effect of coal powder.

[0062] In summary, when multiple groups of convex rings 103c rotate, the shell 101a shakes as a whole, and the sliding of the ring 201b on the guide rod 203a and the action of the spring 203b reduce vibration, reduce the force on the support mechanism 300, ensure stable operation of the equipment, and improve the screening effect of the short filter screen 102b.

[0063] Example 3

[0064] Reference Figure 1 , Figure 6 to Figure 9 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a pulverized coal supply device, including a screening mechanism, a supporting mechanism 300, a feeding mechanism 400, a drying mechanism 500 and a conveyor 600. The supporting mechanism 300 is used to support and install the feeding mechanism 400 and the screening mechanism;

[0065] The feeding mechanism 400 includes a storage component 401 and a diversion component 402. The storage component 401 is used to store coal powder, and the diversion component 402 is used to unload coal powder.

[0066] Specifically, the support mechanism 300 includes a main frame 301, a side rod 302 fixedly connected to the inner side of the main frame 301, and a support frame 303 fixedly connected to the top of the main frame 301;

[0067] The inner side of the support frame 303 is fixedly connected with a side block 303a, the top of the support frame 303 is fixedly connected with a top block 303b, and the first mounting frame 202a and the second mounting frame 202b are mounted and connected with the support frame 303 and the side block 303a by bolts.

[0068] The storage component 401 includes a feed bin 401a, a feed pipe 401b fixedly connected to the bottom end of the feed bin 401a, and a fixing frame 401c installed on the outside of the feed bin 401a by bolts, and U-shaped frames 401d are fixedly connected to both ends of the fixing frame 401c, and the U-shaped frame 401d is installed on the outside of the top block 303b by bolts.

[0069] The diversion component 402 includes a second motor 402a adapted to be installed on the outside of the discharge pipe 401b, a connecting shaft 402b fixedly connected to the output end of the second motor 402a, and a round roller 402c fixedly connected to the outside of the connecting shaft 402b, a groove 402d is provided on the outside of the round roller 402c, and the round roller 402c is located inside the discharge pipe 401b.

[0070] The cleaned coal powder is stored inside the feed bin 401a. When the second motor 402a is started, the operation of the second motor 402a will drive the connecting shaft 402b and the round roller 402c fixed on the outside of the connecting shaft 402b to rotate. The rotating round roller 402c cooperates with the groove 402d to continuously and intermittently discharge the coal powder inside the feed bin 401a, thereby realizing the output of coal powder.

[0071] At the same time, the continuous intermittent discharge method can make the coal powder fall on the surface of the short filter screen 102b in sections, so that the short filter screen 102b can screen the coal powder, thereby reducing the pressure of the short filter screen 102b on the coal powder screening, and then improving the screening effect of the short filter screen 102b on the coal powder.

[0072] In summary, the cleaned coal powder is stored in the feed bin 401a. When the second motor 402a is started, its operation drives the connecting shaft 402b and the round roller 402c, and the round roller 402c cooperates with the groove 402d to achieve continuous intermittent discharge of the coal powder, thereby completing the output of the coal powder. This intermittent discharge method allows the coal powder to be distributed on the short filter screen 102b in sections, reducing the screening pressure and improving the screening effect.

[0075] By starting the heater 501, the heater 501 will transport hot air to the branch pipes 503 on both sides through the main pipe 502, and then input the hot air into the interior of the shell 101a through the branch pipe 504, so as to effectively dry the coal powder in the screening process.
