Description

Technical Field

[0001] This utility model relates to the field of coal bunker anti-blockage technology, specifically to a hyperbolic raw coal bunker with a compartmentalized function. Background Technology

[0002] With social development, the coal and other materials used in factories and enterprises have become increasingly diverse. A crucial step in the use of coal and other materials is transportation. Currently, most of these are delivered using silo-based feeding. However, during the feeding process, due to the high mud or water content in the coal or other materials, blockages and adhesions frequently occur inside the silo. As the material is continuously transported, these blockages and adhesions become increasingly severe, seriously affecting the safe and stable operation of the unit and significantly reducing transportation and production efficiency. For the silos themselves, a bucket silo is generally used, with a large inlet and a small outlet, and a small cross-section at the coal discharge point. A slide gate valve is used for opening and closing. The disadvantages of this method are: if the silo becomes clogged during peak production periods and is not cleared in time, even if the slide gate valve is open, the material will not fall, affecting normal production; traditional bucket silos rely on gravity for coal discharge, but in use, the friction between the material and the silo wall causes a large amount of material to accumulate on the surface, increasing the material aggregation force and significantly affecting the coal discharge speed; especially when the coal is moist, the phenomenon of coal sticking to the walls or bridging during flow increases significantly, affecting the normal flow of coal and the discharge efficiency. Utility Model Content

[0003] To address the aforementioned deficiencies, the purpose of this utility model is to provide a hyperbolic raw coal silo with a partition function. Not only is the hyperbolic raw coal silo itself hyperbolic in shape, which helps maintain the flowability of materials, but it also has a partition function. This partition function allows for the addition of different types of coal on both sides of the partition, achieving coal diversification. Furthermore, if one silo becomes congested, the other silo can still operate normally, ensuring normal production during peak periods.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a hyperbolic raw coal silo with a compartmentalized function, comprising a raw coal silo, a double-sided split valve, and a first hyperbolic transition silo connected sequentially from top to bottom. The raw coal silo is divided into a straight section coal silo and a second hyperbolic transition silo. A partition assembly is vertically installed in the center of the raw coal silo to divide it into two compartments. Radar level gauges are installed on the top of each compartment. A discharge port is located in the center of the double-sided split valve. The center of the discharge port is equipped with a baffle corresponding to the outlets of the two compartments. Valve plates are installed on both sides of the discharge port. The valve plates are connected to a hydraulic cylinder to achieve full opening and closing of the discharge port or single valve plate opening and closing. The first hyperbolic transition silo and the second hyperbolic transition silo are in the shape of a hyperbolic cone.

[0005] Furthermore, the double-sided split valve is composed of multiple crossbeams and longitudinal beams. The valve plate surface is provided with sliding wheels that are tangent to the inner wall of the longitudinal beams. When the valve plate moves, the sliding wheels slide freely along the inner wall of the longitudinal beams. Below the valve plate and perpendicular to the inner wall of the two longitudinal beams, there are also multiple fixed shafts. Support wheels for supporting the valve plate are sleeved on the outside of the fixed shafts. When the valve plate moves, the support wheels slide freely. The sliding wheels and support wheels meet the sliding support requirements of the valve plate.

[0006] The baffle assembly is formed by setting a fastening frame between two baffles. The fastening frame is spliced ​​together by multiple horizontal and vertical supports and welded together. Both horizontal and vertical supports are provided with bolt holes. Fasteners are installed in the bolt holes to connect with the vertical plate. The baffle assembly is provided with a herringbone-shaped flow guide cap on the top.

[0007] Hydraulic cylinders are installed on both sides of the valve plate, with two hydraulic cylinders corresponding to each valve plate. The hydraulic cylinders are connected to the valve plate through a connecting plate, which drives the valve plate to open or close. A sealing plate is installed above the valve plate of the double-sided valve, and a hydraulic station connected to the hydraulic cylinder is provided on the surface of the sealing plate.

[0008] The outer walls of the first and second hyperbolic transition chambers are also equipped with multiple air hammers.

[0009] Near the bottom of the inner wall of the longitudinal beam, a remote limit switch and a near limit switch are fixedly installed; a limit rod is fixedly installed on the bottom surface of the valve plate, and the extension length of the limit rod is sufficient to touch the remote limit switch or the near limit switch; when the feed port needs to be opened, the valve plate moves away from the feed port, the limit rod touches the remote limit switch, and the valve plate stops moving, indicating that the valve plate has retracted into place; conversely, when the feed port needs to be closed, the valve plate moves towards the feed port, the limit rod touches the near limit switch, and the valve plate stops moving, indicating that the valve plate has extended into place.

[0010] The partition provided in this utility model changes the traditional method of simply adding a single partition to the partition compartment. Instead, it transforms the partition into a partition assembly consisting of two partitions and a fastening frame. This assembly has high strength, long service life, reduces the frequency of maintenance, and effectively ensures the normal operation of production.

[0011] When the double-sided valve of this invention is closed, the telescopic rod of the hydraulic cylinder is in the retracted state, and at this time, both valve plates at both ends are closed to the discharge port. In use, if a partition compartment requires single-sided use, the hydraulic cylinder on that side is activated, causing the telescopic rod of the hydraulic cylinder on that side to extend and activate the valve plate on one side only, thus satisfying single-sided use. If a partition compartment requires double-sided use, both hydraulic cylinders are activated, causing the telescopic rods of both hydraulic cylinders to extend and activate the valve plates on both sides, thus meeting the production needs.

[0012] The partitioned bin formed in this utility model not only allows for the addition of different types of coal on both sides of the partition, achieving coal diversification, but also ensures normal production during peak production periods if one bin becomes congested while the other bin remains operational. Regarding the application of the partitioned bin, traditional slide gate valves can only be aligned with one outlet, achieving either complete closure or full opening. The double-sided opposing valve in this application allows for the individual opening and closing of both valve plates, or complete opening and closing, enabling the partitioned bin to freely choose to open or close one side of the valve plate when experiencing blockages or using other types of materials. This allows for flexible material allocation and ensures continuous production.

[0013] This utility model has a baffle plate set at the center of the feeding cylinder, which can effectively prevent the valve plate from going out of control and can also prevent the two valve plates from jamming when they are closed at the same time.

[0014] The sliding wheels and support wheels provided on the surface of the valve plate in this invention form a support for the valve plate, which effectively ensures that the valve plate does not deviate and has low resistance during reciprocating movement.

[0015] The radar level gauge installed in this invention can detect the amount of material in the compartment, which facilitates its rational use.

[0016] The hyperbolic transition bin design used in this invention features a hyperbolic bin shape, which helps maintain material flowability, reduces material accumulation on the bin walls, reduces friction between the material and the bin walls, lowers material cohesion, and improves the cleaning efficiency and discharge speed of the coal bin.

[0017] The beneficial effects of this utility model are as follows: By setting hydraulic stations on the surface of the valve plate and driving two hydraulic cylinders on both sides of the valve body frame structure, the design changes the previous design where the hydraulic stations or electric push rods used in the transmission state were placed at both ends of the external side of the slide gate valve. The new design reduces the length of the valve body, effectively saves production space, and is convenient for production under different working conditions. For such a large valve, transportation, installation, and subsequent maintenance become more convenient. The partition assembly provided in this utility model has a robust structure and long service life after welding, which can meet the long-term use needs of power plants. Attached Figure Description

[0026] See appendix Figure 1-6 This is one embodiment of the present invention, disclosing a hyperbolic raw coal silo with a compartmentalized function, comprising a raw coal silo, a double-sided split valve, and a first hyperbolic transition silo 24 connected sequentially from top to bottom. The raw coal silo is divided into a straight section coal silo 23 and a second hyperbolic transition silo 25. A partition assembly 22 is set vertically in the center of the raw coal silo to divide it into two compartments. Radar level gauges 27 are respectively installed on the top of the compartments. A discharge port 1 is provided in the center of the double-sided split valve. The center of the discharge port 1 is connected to the outlets of the two compartments by a baffle 11. Valve plates 8 are provided on both sides of the discharge port 1. The valve plates 8 are connected to a hydraulic cylinder 7 to reciprocate to realize the full opening and closing of the discharge port 1 or the opening and closing of a single valve plate 8. The first hyperbolic transition silo 24 and the second hyperbolic transition silo 25 are in the shape of a hyperbolic cone. The hyperbolic transition bin design features a hyperbolic shape, which helps maintain material flowability, reduces material accumulation on the bin walls, reduces friction between the material and the bin walls, lowers material cohesion, and improves the cleaning efficiency and discharge speed of the coal bin.

[0027] The double-sided opening valve is composed of multiple crossbeams 13 and longitudinal beams 12. A sliding wheel 19, tangential to the inner wall of the longitudinal beam 12, is provided on the surface of the valve plate 8. This sliding wheel 19 is movably connected to a support plate 5 on the surface of the valve plate 8. When the valve plate 8 moves, the sliding wheel 19 slides freely along the inner wall of the longitudinal beam 12. Below the valve plate 8 and perpendicular to the inner walls of the two longitudinal beams 12, multiple fixed shafts 20 are also provided. Support wheels 21, used to support the valve plate 8, are sleeved on the outside of the fixed shafts 20. When the valve plate 8 moves, the support wheels 21 slide freely. The sliding wheels 19 and support wheels 21 satisfy the sliding support requirements of the valve plate 8. The sliding wheels 19 and support wheels 21 provided on the surface of the valve plate 8 in this invention form a support for the valve plate 8, effectively ensuring that the valve plate 8 does not deviate and that the resistance during reciprocating movement is small.

[0028] The partition assembly 22 is formed by setting a fastening frame between two partitions 30. The fastening frame is spliced ​​together by multiple horizontal supports 31 and vertical supports 32 and then welded together. Bolt holes are provided on both the horizontal supports 31 and vertical supports 32. Fasteners are installed on the bolt holes to connect with the upright plate. The top of the partition assembly 22 is provided with a herringbone-shaped flow guide cap 28. The partition 30 in the partition compartment provided in this utility model changes the traditional method of adding only a single partition 30 to the partition compartment. Instead, the partition 30 is changed into a partition assembly 22 consisting of two partitions 30 and a fastening frame. The assembly has high strength, long service life, reduces the frequency of maintenance, and effectively ensures the normal operation of production.

[0029] Hydraulic cylinders 7 are located on both sides of valve plates 8, with two hydraulic cylinders 7 corresponding to each valve plate 8. The hydraulic cylinders 7 are connected to the valve plates 8 via a connecting plate 18, which passes through a long slot 10 outside the longitudinal beam 12, causing the valve plates 8 to open or close. A sealing plate 17 is installed above the valve plates 8 of the double-sided valve, and a hydraulic station 6 connected to the hydraulic cylinders 7 is provided on the surface of the sealing plate 17. In this invention, when the double-sided valve is closed, the telescopic rods of the hydraulic cylinders 7 are retracted, and both valve plates 8 are closed relative to the discharge port 1. During use, if a compartment requires single-sided operation, the hydraulic cylinder 7 on that side is activated, extending its telescopic rod and moving only one valve plate 8 to meet single-sided operation. If a compartment requires double-sided operation, both hydraulic cylinders 7 are activated, extending their telescopic rods and moving both valve plates 8 to meet production needs.

[0030] The outer walls of the first hyperbolic transition chamber 24 and the second hyperbolic transition chamber 25 are also equipped with multiple air hammers 29, which improve the efficiency of material feeding to a certain extent.

[0031] A remote limit switch 15 and a near-end limit switch 16 are fixedly installed on the inner wall of the longitudinal beam 12 near the bottom; a limit rod 14 is fixedly installed on the bottom surface of the valve plate 8, and the extension length of the limit rod 14 is sufficient to touch the remote limit switch 15 or the near-end limit switch 16; when the feed port 1 needs to be opened, the valve plate 8 moves away from the feed port 1, the limit rod 14 touches the remote limit switch 15, and the valve plate 8 stops moving, indicating that the valve plate 8 has retracted into place; conversely, when the feed port 1 needs to be closed, the valve plate 8 moves towards the feed port 1, the limit rod 14 touches the near-end limit switch 16, and the valve plate 8 stops moving, indicating that the valve plate 8 has extended into place.

[0032] The partitioned bin formed in this utility model not only allows for the addition of different types of coal on both sides of the partition plate 30 to achieve coal diversification, but also ensures normal production during peak production periods if one side of the bin becomes congested while the other bin remains operational. Regarding the application of the partitioned bin, the original slide gate valve can only be aligned with one outlet, achieving either complete closure or complete opening. The double-sided opposing valve in this application allows for the individual opening and closing of the two valve plates 8, or complete opening and closing, enabling the partitioned bin to freely choose to open or close one side of the valve plate 8 when there is material blockage or when using other types of materials. This allows for flexible material allocation and ensures continuous production.

[0033] This utility model provides a baffle 11 at the center of the feeding cylinder, which can effectively prevent a valve plate 8 from going out of control and can also prevent the two valve plates 8 from jamming when they are closed at the same time.

[0034] The radar level gauge 27 installed in this invention can detect the amount of material in the compartment, which facilitates its rational use.

[0035] The above description is only a preferred embodiment of the present utility model. The above specific embodiments are not intended to limit the present utility model. Any modifications, alterations or equivalent substitutions made by those skilled in the art based on the above description shall fall within the protection scope of the present utility model.
