Description

Technical Field

[0001] The present application relates to the technical field of coal transportation, and in particular to a coal distribution device. Background Art

[0002] In industrial production, coal is usually used as fuel. Usually, coal needs to be compounded to control important coal quality parameters such as calorific value, volatile matter and sulfur content of the coal entering the furnace, to meet the requirements of equipment load, slagging and emission constraints, and to ensure the economy and safety of equipment operation.

[0003] Therefore, it is necessary to provide a coal distribution device to meet the distribution needs of coal. Utility Model Content

[0004] Based on the above-mentioned deficiencies, the present application provides a coal distribution device to improve the distribution problem of compound coal in the related technology.

[0005] This application is implemented as follows:

[0006] The example of the present application provides a coal distribution device, including a silo and a feeder. A partition is vertically arranged inside the silo to separate the chamber inside the silo into a first chamber and a second chamber; the transverse cross section of the partition is S-shaped; the discharge port of the silo is connected to the feed port of the feeder.

[0007] In the above implementation process, a partition is vertically arranged in the silo of the coal distribution device, and the partition can be used to separate the chamber inside the silo into a first chamber and a second chamber, and the two types of coal required to be compounded can be placed in the first chamber and the second chamber, and then the two types of coal are transported to the feeder through the discharge port of the silo, and the feeder is used to transport the compounded coal to the rear-end feeding equipment. Using a partition to separate the silo can not only simultaneously transport two different types of coal to the rear-end feeder, but also simplify the structure of the coal distribution device.

[0008] In addition, a partition with an S-shaped transverse section is provided, which has a smooth surface, can facilitate coal transportation, and improve distribution efficiency and quality. Moreover, the partition with an S-shaped transverse section also has good mechanical properties. When different coals are placed in the first chamber and the second chamber, the probability of deformation of the partition due to the different properties of the coal on both sides of the partition, such as hardness, humidity, viscosity, etc., can be reduced, and the service life and distribution quality of the coal distribution device can be improved.

[0009] In an optional embodiment, the thickness of the partition is 10-20 mm.

[0010] In the above implementation process, the thickness of the partition is 10-20 mm, which can make the partition have good mechanical properties, reduce the probability of deformation of the partition during the distribution process, and thus improve the service life and distribution quality of the coal distribution device.

[0011] In combination with the first aspect, in an optional embodiment, the ratio of the radius of the top of the silo to the radius of curvature of the transverse cross section of the partition is 1:1-1.5.

[0012] In the above implementation process, the ratio of the radius of the top of the silo to the curvature radius of the transverse section of the partition is 1:1-1.5. On the premise of improving the mechanical properties of the partition, the probability of the coal on both sides of the partition being stuck in the curved partition or the connection between the partition and the inner wall of the silo can be reduced, thereby improving the coal transportation efficiency and the quality of coal distribution.

[0013] In an optional embodiment, the silo includes a cylinder and a hopper which are connected to each other, the hopper is located below the cylinder, and the partition extends from the feed inlet of the cylinder to the discharge port of the hopper.

[0014] In the above implementation process, the silo includes a cylinder and a hopper. The hopper can promote the flow of coal toward the discharge port, and the cylinder can increase the storage space above the silo.

[0015] In an optional embodiment, the discharge port is provided with a slide door, which can selectively connect the first chamber and / or the second chamber to the feed port of the feeder.

[0016] In the above implementation process, a plug door is set at the discharge port of the silo, and the feeding amount of the first chamber and the second chamber to the feeder can be adjusted according to the material distribution requirements to meet the coal distribution requirements of various proportions.

[0017] In an optional embodiment, the coal distribution device further includes an auxiliary feeding mechanism, which is used to make the coal in the first chamber and / or the second chamber flow toward the discharge port.

[0018] In the above implementation process, an auxiliary feeding mechanism is provided, which can make the coal in the first chamber and the second chamber flow toward the discharge port, and can improve the distribution efficiency. Usually, the ratio of the two types of coal in the feeder can be regulated by regulating the conveying speed of the two chambers to convey the coal to the feeder, and the conveying speed can be adjusted by the opening of the plug door. Under the set opening, if the coal in a chamber suddenly stops flowing, or as the conveying time goes by, the coal agglomerates and causes the fluidity to decrease, it will cause a large deviation between the actual conveying speed and the set conveying speed, which will cause the actual ratio of the two types of coal in the feeder to deviate, thereby affecting the quality of coal distribution. The auxiliary feeding mechanism is provided in the coal distribution device provided in the embodiment of the present application, which can reduce the probability of coal interruption or slowing down of the conveying speed, can improve the uniformity of coal flow in the first chamber and the second chamber, and thus can improve the quality of coal distribution.

[0019] In an optional embodiment, the auxiliary feeding mechanism includes a first driving member and a pounding rod, the pounding end of the pounding rod extends into the first chamber and / or the second chamber, and the connecting end of the pounding rod is connected to the first driving member; the first driving member is used to drive the pounding rod to move.

[0020] In the above implementation process, the tamping rod is driven to move by the first driving member, which can disturb the coal in the first chamber and the second chamber, improve the fluidity of the coal, reduce the probability of coal agglomeration or adhesion to the inner wall of the chamber, and thus improve the efficiency and quality of coal distribution.

[0021] In an optional embodiment, the first driving member is selected from a rotary motor or a telescopic cylinder.

[0022] In the above implementation process, a rotary motor or a telescopic cylinder is used to drive the tamping rod to perform corresponding rotational movement or telescopic movement, thereby disturbing the coal in the chamber, improving the fluidity of the coal, and improving the efficiency and quality of coal distribution.

[0023] In an optional embodiment, the auxiliary feeding mechanism includes a second driving member and a vibrating member, and the second driving member is arranged on the outer wall of the silo to drive the vibrating member to selectively impact the outer wall of the silo.

[0024] In the above implementation process, the second driving member is used to drive the vibrating member to impact the outer wall of the silo, which can cause the coal in the silo to vibrate, reduce the probability of coal agglomeration or adhesion to the inner wall of the silo, improve the fluidity of the coal, and thus improve the efficiency and quality of coal distribution.

[0025] In an optional embodiment, the vibrating member includes a bracket, a connecting shaft and an eccentric wheel. The bracket is arranged on the outer wall of the silo and protrudes from the outer wall of the silo by a preset distance. The connecting shaft is rotatably connected to one end of the bracket away from the outer wall of the silo. The eccentric wheel is sleeved on the connecting shaft. The second driving member drives the connecting shaft to rotate. The rotation of the connecting shaft drives the eccentric wheel to rotate, so as to selectively impact the outer wall of the silo.

[0026] In the above implementation process, a bracket is arranged on the outer wall of the silo, a connecting shaft can be arranged at one end of the bracket pointing to the outer wall of the silo, an eccentric wheel is arranged on the connecting shaft, and the connecting shaft is driven to rotate by a second driving member, thereby driving the eccentric wheel to rotate. The eccentric wheel can intermittently hit the outer wall of the silo during rotation, thereby causing the coal in the silo to vibrate, reducing the probability of coal agglomeration or adhesion to the inner wall of the silo, improving the fluidity of the coal, and thereby improving the efficiency and quality of coal distribution.

[0038] In industrial production, coal is widely used as a fuel. It is usually necessary to compound the coal to control important coal quality parameters such as the calorific value, volatile matter and sulfur content of the coal entering the furnace, so as to adapt to the requirements of constraints such as equipment load, slagging and emissions, and ensure the economy and safety of equipment operation.

[0039] Therefore, the present application provides a coal distribution device 1, which can improve the distribution problem of compound coal to a certain extent. In order to make the purpose, technical solution and advantages of the embodiment of the present application clearer, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

[0040] Please combine Figure 1 and Figure 2 The present application example provides a coal distribution device 1, including a silo 10 and a feeder 20.

[0041] Please combine Figure 1 and Figure 3 The silo 10 has a chamber 11 inside, and a partition 12 is vertically arranged in the chamber 11 to separate the chamber 11 inside the silo 10 into a first chamber 111 and a second chamber 112. The transverse cross section of the partition 12 is S-shaped.

[0042] Please continue reading Figure 1 and Figure 2 The discharge port of the silo 10 is connected to the feed port of the feeder 20.

[0043] A partition 12 is vertically arranged in the silo 10 of the coal distribution device 1, and the partition 12 can be used to divide the chamber 11 inside the silo 10 into a first chamber 111 and a second chamber 112. The two types of coal required to be compounded can be placed in the first chamber 111 and the second chamber 112, and then the two types of coal are transported to the feeder 20 through the discharge port of the silo 10, and the feeder 20 is used to transport the compounded coal to the rear-end material equipment.

[0044] If the vertical partition 12 is not provided in the silo 10, in order to convey a variety of different coals to the feeder 20, it is necessary to provide two independent silos 10 in the coal distribution device 1, and use two conveying pipelines to connect the two silos 10 to the feeder 20 respectively. Providing multiple silos 10 and conveying pipelines connected to the silos 10 in the coal distribution device 1 will not only make the structure of the coal distribution device 1 complicated, but also make the preparation and operation costs of the device high. In the coal distribution device 1 provided in the embodiment of the present application, the silos 10 are separated by the partition 12, which can not only simultaneously convey two different types of coal to the feeder 20 at the rear end, but also simplify the structure of the coal distribution device 1 and reduce costs.

[0045] Furthermore, the example of the present application provides a partition 12 with an S-shaped transverse cross-section, which has a smooth surface, can facilitate coal transportation and improve distribution efficiency and quality.

[0046] If a zigzag partition 12 is provided in the silo 10 , the coal may be easily stuck in the sharp corners of the zigzag partition 12 during coal transportation, which will aggravate coal accumulation, affect the coal transportation speed, and further affect the distribution efficiency and quality of the coal distribution device 1 .

[0047] Furthermore, when the silo 10 is provided with a broken line partition 12, due to the different properties of the coal on both sides of the partition 12, such as the conveying speed and hardness, an uneven squeezing force will be generated on the partition 12, and the partition 12 is easily deformed due to stress concentration at the angle of the partition 12. If the partition 12 is deformed during the conveying process, the deformed partition 12 will hinder the coal, which will affect the distribution efficiency and quality of the coal distribution device 1.

[0048] If a flat partition 12 is provided in the silo 10, due to the different properties of the coal on both sides of the partition 12, such as the conveying speed and hardness, uneven squeezing pressure will be generated on both sides of the partition 12, thereby causing deformation of the partition 12. If the partition 12 is deformed during the conveying process, the deformed partition 12 will hinder the coal, thus affecting the distribution efficiency and quality of the coal distribution device 1.

[0049] In the coal distribution device 1 provided in the example of the present application, the chamber 11 in the silo 10 is divided into a first chamber 111 and a second chamber 112 by a partition 12 with an S-shaped transverse cross-section. The partition 12 with an S-shaped transverse cross-section has good mechanical properties and can relieve stress concentration. When different coals are placed in the first chamber 111 and the second chamber 112, the probability of deformation of the partition 12 due to the differences in hardness, humidity, viscosity and other properties of the coal on both sides of the partition 12 can be reduced, thereby improving the service life and distribution quality of the coal distribution device.

[0050] Furthermore, in some possible embodiments, the ratio of the radius of the top of the silo 10 to the curvature radius R of the transverse cross section of the partition 12 is 1:1-1.5.

[0051] The radius of the top of the silo 10 refers to the radius of the feed inlet at the top of the silo 10. Exemplarily, when the silo 10 includes a cylinder 13 and a hopper 14, the radius of the top of the silo 10 is the radius of the cylinder 13.

[0052] Exemplarily, the ratio of the radius of the top of the silo 10 to the curvature radius R of the transverse cross section of the partition 12 may be 1:1, 1:1.1, 1:1.2, 1:1.3, 1:1.4 or 1:1.5, or a range between any two of them.

[0053] Setting the ratio of the radius of the top of the silo 10 to the radius of curvature R of the transverse section of the partition 12 to 1:1-1.5 can further alleviate the stress concentration of the partition 12 and improve the mechanical properties of the partition 12. In addition, setting the ratio of the radius of the top of the silo 10 to the radius of curvature R of the transverse section of the partition 12 to 1:1-1.5, the transition between two adjacent arcs is relatively smooth, which can reduce the probability of coal getting stuck between the arc segments. In addition, the connection between the partition 12 and the inner wall of the silo 10 has an appropriate gap, which can reduce the probability of coal getting stuck between the partition 12 and the inner wall of the silo 10, improve the coal transportation efficiency, and improve the quality of coal distribution.

[0054] Furthermore, in some possible embodiments, the thickness of the partition 12 may be 10-20 mm.

[0055] Exemplarily, the thickness of the partition 12 may be set to be one of 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm or 20 mm, or a range between any two thereof.

[0056] Furthermore, in some possible embodiments, the material of the partition 12 may be selected from stainless steel.

[0057] For some possible embodiments, please refer to Figure 1 and Figure 2 The silo 10 includes a cylinder 13 and a hopper 14 which are connected to each other. The hopper 14 is located below the cylinder 13 , and the partition 12 extends from the feed inlet of the cylinder 13 to the discharge port of the hopper 14 .

[0058] The silo 10 includes a barrel 13 and a hopper 14. The hopper 14 can promote the flow of coal toward the discharge port, and the barrel 13 can increase the storage space above the silo 10. The feed port of the barrel 13 from the partition 12 extends to the discharge port of the hopper 14, which can facilitate the delivery of different coals to the feeder 20.

[0059] Further, in some possible embodiments, please continue to refer to Figure 1 and Figure 2 The discharge port is provided with a plug-in door 30 , which can selectively connect one or both of the first chamber 111 or the second chamber 112 to the feed port of the feeder 20 .

[0060] A plug-in door 30 is provided at the discharge port of the silo 10, and the feeding amount of the first chamber 111 and the second chamber 112 delivered to the feeder 20 can be adjusted according to the material distribution requirements to meet the coal distribution requirements of various proportions.

[0061] For example, the gate door 30 may be used to control the opening of the discharge port at the first chamber 111 , so as to adjust the speed of conveying the coal from the first chamber 111 to the feeder 20 .

[0062] For example, the gate door 30 may be used to control the opening of the discharge port at the second chamber 112 , thereby adjusting the speed at which the coal is transported from the second chamber 112 to the feeder 20 .

[0063] The conveying speed of the coal in the first chamber 111 and the second chamber 112 to the feeder 20 can be adjusted accordingly according to the characteristics of the coal.

[0064] The present application does not limit the specific type of the gate 30. In some possible embodiments, the gate 30 may be a single-opening gate. In order to facilitate the separate control of the conveying speed of the coal in the first chamber 111 and the second chamber, two single-opening gates 30 may be provided at the discharge port of the silo 10.

[0065] Exemplarily, a single-opening plug-in door 30 is provided at the discharge port corresponding to the first chamber 111 , and a single-opening plug-in door 30 is provided at the discharge port corresponding to the second chamber 112 .

[0066] Furthermore, a gap is formed between the discharge port of the silo 10 and the feed port of the feeder 20, and the single-opening plug-in door 30 may include a plug-in plate and a driving member for driving the plug-in plate to extend into or out of the gap.

[0067] When the driving member drives the insert plate to extend into the gap between the discharge port of the silo 10 and the feed port of the feeder 20, the insert plate will close the portion of the discharge port corresponding to the first chamber 111 or the second chamber 112, and stop transporting the coal in the corresponding chamber to the feeder 20.

[0068] When the driving member drives the insert plate to exit the gap between the discharge port of the silo 10 and the feed port of the feeder 20 , the insert plate will expose the portion of the discharge port corresponding to the first chamber 111 or the second chamber 112 , so that the coal in the corresponding chamber can be transported to the feeder 20 .

[0069] When it is necessary to adjust the conveying speed of the coal in the first chamber 111 or the second chamber 112 , the driving member can be used to drive the inserting depth of the gate into the gap.

[0070] Alternatively, in another possible embodiment, a double-opening plug door 30 may be provided between the discharge port of the silo 10 and the feed port of the feeder 20 .

[0071] Exemplarily, the double-opening sliding door 30 has two sliding plates and a driving member for driving the two sliding plates to move closer to or away from each other.

[0072] Since coal often comes in various forms such as powder, granular and lump, and has the characteristics of high humidity, high ash content and high viscosity, it is easy for the coal to adhere to the wall of the silo 10 during transportation, reducing the actual transportation speed of the coal and even causing interruption of flow, which will affect the quality and efficiency of coal distribution.

[0073] In order to improve the distribution quality and distribution efficiency of the coal distribution device 1, in some possible embodiments, please refer to Figure 4 The coal distribution device 1 is further provided with an auxiliary feeding mechanism 40. The auxiliary feeding mechanism 40 is used to make the coal in the first chamber 111 and / or the second chamber 112 flow toward the discharge port.

[0074] The coal distribution device 1 provided in the embodiment of the present application is provided with an auxiliary feeding mechanism 40, which can reduce the probability of coal flow interruption or slowdown of the conveying speed, and can improve the uniformity of coal flow in the first chamber 111 and the second chamber 112, thereby improving the quality of coal distribution.

[0075] Further, the present application does not limit how the auxiliary feeding mechanism 40 enables the coal in the first chamber 111 and / or the second chamber 112 to flow toward the discharge port. In some possible embodiments, please continue to refer to Figure 4 The auxiliary feeding mechanism 40 may include a first driving member 41 and a pounding rod 42, the pounding end of the pounding rod 42 extends into the first chamber 111 and the second chamber 112, and the connecting end of the pounding rod 42 is connected to the first driving member 41; the first driving member 41 is used to drive the pounding rod 42 to move.

[0076] Exemplarily, the auxiliary feeding mechanism 40 may include two tamping rods 42 , and tamping ends of the two tamping rods 42 extend into the first chamber 111 and the second chamber 112 respectively.

[0077] Furthermore, the two tamping rods 42 may be connected to the same first driving member 41 , and the first driving member 41 simultaneously drives the two tamping rods 42 to move at the same speed to tamping.

[0078] Alternatively, the auxiliary feeding mechanism 40 may be provided with two first driving members 41 , and the two first driving members 41 correspond to each other and independently drive the tamping rod 42 to move.

[0079] Furthermore, the present application does not limit the shape of the tamping rod 42. In a possible embodiment, the tamping rod 42 may include a rotating shaft and a stirring blade disposed at the rotating shaft.

[0080] Exemplarily, the first driving member 41 may be selected from a rotary motor or a telescopic cylinder to drive the tamping rod 42 to telescopically move up and down or to rotate.

[0081] Alternatively, in some other possible embodiments, the auxiliary feeding mechanism 40 may include a second driving member and a vibrating member (not shown in the figure), and the second driving member is arranged on the outer wall of the silo 10 to drive the vibrating member to selectively impact the outer wall of the silo 10.

[0082] By using the second driving member to drive the vibrating member to impact the outer wall of the silo 10, the coal in the silo 10 can be vibrated, reducing the probability of coal agglomeration or adhesion to the inner wall of the silo 10, improving the fluidity of the coal, and thus improving the efficiency and quality of coal distribution.

[0083] Furthermore, the present application does not limit how the second driving member drives the vibrating member to impact the outer wall of the silo 10. In a possible embodiment, the vibrating member includes a bracket, a connecting shaft and an eccentric wheel.

[0084] The bracket is arranged on the outer wall of the silo 10 and protrudes from the outer wall of the silo 10 by a preset distance. The connecting shaft is rotatably connected to one end of the bracket away from the outer wall of the silo 10. The eccentric wheel is sleeved on the connecting shaft. The second driving member drives the connecting shaft to rotate. The rotation of the connecting shaft drives the eccentric wheel to rotate. The eccentric wheel can intermittently hit the outer wall of the silo 10 during the rotation process, thereby vibrating the coal in the silo 10, reducing the probability of coal agglomeration or adhesion to the inner wall of the silo 10, improving the fluidity of the coal, and thus improving the efficiency and quality of coal distribution.

[0085] Exemplarily, the support may be configured in the shape of a gantry, with the pointed direction of the gantry being perpendicular to the side wall of the silo 10 .

[0086] Exemplarily, the second driving member is selected from a rotating motor, which rotates forward and reversely so that the eccentric wheel intermittently hits the outer wall of the silo 10.

[0087] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
