Description

Technical Field

[0001] The utility model relates to the technical field of solid particle material distribution, in particular to an anti-falling coal hopper with reinforcing ribs, an anti-falling small coal hopper with reinforcing ribs, a shunt coal hopper and a shunt coal bunker. Background Art

[0002] The coal distribution device includes a coal bunker and a coal feeder arranged below the coal bunker. The coal bunker includes a coal bunker main body at the upper part and a coal hopper at the lower part. The coal hopper is conical, such as conical or square conical, with the diameter gradually decreasing from top to bottom, and the lower end is the coal outlet. The inclination angle of the wall of the traditional coal hopper remains unchanged from top to bottom, and such a structure is prone to coal blockage.

[0003] In recent years, a new type of coal hopper design form - the shrimp curve coal hopper has emerged in the industry, and this kind of coal hopper has played a positive role in reducing coal blockage. This kind of coal hopper presents two forms. The first form is that the whole coal hopper is composed of multiple sections of frustums of cones with equal or unequal heights spliced and combined, and at least the inclination angles of the frustums of cones at the lower part increase gradually along the downward direction; the second form is that the whole coal hopper includes two parts: an upper coal hopper part at the upper part and a small coal hopper between the upper coal hopper part and the coal feeder. The small coal hopper is a shrimp curve small coal hopper or other forms of small coal hoppers, and this small coal hopper is composed of multiple sections of frustums of cones with equal or unequal heights spliced and combined, and the inclination angles of the frustums of cones increase gradually along the downward direction. No matter which form of coal hopper, the adjacent frustums of cones need to be connected together by welding. For the first form of coal hopper mentioned above, the coal hopper also needs to be connected with the lower part of the coal bunker main body by welding or other means; for the second coal hopper, the small coal hopper needs to be connected with the lower part of the upper coal hopper part.

[0004] However, due to the large self-weight of the coal hopper or small coal hopper itself, and it has to bear the weight of coal during use, there is a risk that the small coal hopper breaks at the welding part, and the actual use situation shows that the breakage occurs from time to time, which not only causes great potential safety hazards but also affects the production progress. Therefore, there is a demand in the industry for a coal hopper that is safe and reliable in use. Summary of the Utility Model

[0039] The following will describe the anti - shedding coal hopper with reinforcing ribs of the present utility model in detail with reference to the accompanying drawings and embodiments. Here, it should be noted that the embodiments of the present utility model are merely illustrative, and they are only used to explain the principle of the present utility model rather than to limit the present utility model.

[0040] In the following description and other parts of this application, the longitudinal direction refers to the extending direction of the coal hopper, that is, the up - down direction during use.

[0041] First embodiment

[0042] First, refer to Figure 1 and Figure 2 , where Figure 1 is a perspective view showing the overall structure of the anti - shedding coal hopper with reinforcing ribs according to the first embodiment of the present utility model, Figure 2 is Figure 1 the front view of the anti - shedding coal hopper with reinforcing ribs shown in Figure 1 and Figure 2As shown, the anti - shedding coal hopper 100 with reinforcing ribs in the first embodiment is a second - type coal hopper, which includes two parts: namely, the upper coal hopper part 1 and the anti - shedding small coal hopper 2 with reinforcing ribs. In this application, the small coal hopper refers to the coal hopper part located between the upper coal hopper part 1 and the flap gate 5 during use. The cross - section of the upper coal hopper part 1 is circular. The anti - shedding small coal hopper 2 with reinforcing ribs can be a small coal hopper in the form of a hyperbola, a small coal hopper with a shrimp - curve, or any other small coal hopper with a circular cross - section. The present utility model does not make a limitation. The anti - shedding small coal hopper with reinforcing ribs is formed by splicing and combining multiple frustums 3 of equal or unequal height.

[0043] Figure 1 and Figure 2 In [the figure], the component referred to by reference numeral 5 is the flap gate, and the component referred to by reference numeral 6 is the communication channel. During the use of the anti - shedding coal hopper with reinforcing ribs, the flap gate is arranged between the anti - shedding coal hopper with reinforcing ribs and the communication channel 6 to control the opening and closing of the communication channel, and the other end of the communication channel is connected to a coal feeder (not shown in the figure).

[0044] Adjacent frustums 3 of the anti - shedding small coal hopper 2 with reinforcing ribs are connected to each other by means such as welding, thereby forming the anti - shedding small coal hopper body with reinforcing ribs.

[0045] According to the technical solution of the present utility model, please refer to Figure 1 and Figure 2 , reinforcing ribs 9 are provided on the anti - shedding small coal hopper 2 with reinforcing ribs. The number of reinforcing ribs 9 is not limited and can be selected according to the actual application scenario. In the illustrated embodiment, four reinforcing ribs 9 are used. When the number of reinforcing ribs 9 is multiple, the reinforcing ribs 9 are arranged at intervals along the circumferential direction.

[0046] Continuing to refer to Figure 1 and Figure 2 , the reinforcing ribs 9 are in the shape of strip - like plates. In the assembled state, their plate surfaces are in contact with the outer surface of the anti - shedding small coal hopper body with reinforcing ribs, and are fixedly connected at the contact position by means such as welding. The reinforcing ribs 9 extend in the up - and - down direction on the outer surface of the anti - shedding small coal hopper body. The lower end extends past the connection part of the two lowermost frustums and is located between the longitudinal ends of the lowermost frustum, and the upper end extends past the uppermost frustum for connection to the lower end of the upper coal hopper part 1 by means such as welding.

[0047] In the solution described above, the upper end of the reinforcing rib 9 extends beyond the uppermost frustum. As an alternative technical solution, the upper end of the reinforcing rib 9 may not extend beyond the uppermost frustum, but may be located between the longitudinal ends of the uppermost frustum. In this case, if it is necessary to strengthen the connection strength between the upper coal hopper part 1 and the anti-detachment small coal hopper 2 with the reinforcing rib, other solutions may be adopted, such as using the reinforcing plate 8 mentioned later, etc.

[0048] In addition, as an alternative technical solution, the reinforcing rib 9 does not have to extend along the entire length of the anti-detachment small coal hopper 2 with the reinforcing rib, but the longitudinal length of the reinforcing rib 9 can be shortened, and it can be arranged only at the positions of the upper frustums where the force is relatively large.

[0049] In the technical solution described above, the reinforcing rib 9 is arranged to extend in the up and down direction along the outer surface of the anti-detachment small coal hopper main body with the reinforcing rib, but the present invention is not limited thereto, and the reinforcing rib 9 can also be arranged to extend spirally along the outer surface of the anti-detachment small coal hopper main body with the reinforcing rib.

[0050] As a preferred solution, in order to strengthen the connection strength between the frustums, a reinforcing hoop 7 can be additionally arranged at the connection between two adjacent frustums, and the reinforcing hoop 7 is welded to the frustum at the up and down longitudinal ends. Preferably, the reinforcing hoop 7 is arranged below the reinforcing rib 9 and is located between the reinforcing rib 9 and the anti-detachment small coal hopper main body with the reinforcing rib. In addition, as another alternative solution, considering that the upper frustums of the anti-detachment small coal hopper main body with the reinforcing rib are subjected to relatively large tensile forces (including the gravity exerted by the lower frustums and the coal material and the pressure exerted by the upper coal material) during actual use, while the lower frustums of the anti-detachment small coal hopper main body with the reinforcing rib are subjected to relatively small tensile forces during actual use, the reinforcing hoop 7 can also be arranged only at the connections between two adjacent upper frustums of the anti-detachment small coal hopper main body with the reinforcing rib, and the reinforcing hoop is not arranged at the connections between two adjacent lower frustums of the anti-detachment small coal hopper main body with the reinforcing rib.

[0051] Continue to refer to Figure 1 and Figure 2 , the upper coal hopper part 1 of the anti-detachment coal hopper with the reinforcing rib and the anti-detachment small coal hopper 2 with the reinforcing rib are also connected to each other by means such as welding. For the same consideration, as a preferred solution, a reinforcing hoop 17 is arranged at the connection part between the upper coal hopper part 1 and the anti-detachment small coal hopper 2 with the reinforcing rib. Preferably, the reinforcing hoop 17 is arranged below the reinforcing rib 9 and is located between the reinforcing rib 9 and the lower ends of the anti-detachment small coal hopper main body with the reinforcing rib and the upper coal hopper part 1.

[0052] In addition, in order to reinforce the connection strength between the upper coal hopper part 1 and the anti-detachment small coal hopper 2 with the reinforcing rib, as a preferred solution, asFigure 1 and Figure 2 As shown in Figure 2 , a reinforcement plate 8 is also provided at the connection part between the upper coal hopper part 1 and the anti - shedding small coal hopper 2 with reinforcing ribs. The reinforcement plate 8 extends in the up - and - down direction, and its plate surface substantially coincides with the outer surface of the coal hopper. The upper plate surface is in contact with the lower end surface of the upper coal hopper part 1, and the lower plate surface is in contact with the conical surface at the uppermost end of the anti - shedding small coal hopper 2 with reinforcing ribs, and they are connected by welding.

[0053] By taking measures such as setting reinforcing hoops and reinforcement plates, the connection strength of the anti - shedding small coal hopper 2 with reinforcing ribs itself and the connection strength between the upper coal hopper part 1 and the anti - shedding small coal hopper 2 with reinforcing ribs are further improved.

[0054] Figures 3 - 5 The figure shows other alternative solutions of the present utility model. Compared with the Figure 1 and Figure 2 shown solutions, Figure 3 in the solution shown in Figure 3 , the reinforcement plate is not provided; Figure 4 in the solution shown in Figure 4 , the reinforcing hoop is not provided; Figure 5 in the solution shown in Figure 5 , neither the reinforcement plate nor the reinforcing hoop is provided.

[0055] In the technical solution described above, the cross - section of the anti - shedding coal hopper with reinforcing ribs is circular, that is, the cross - sections of both the upper coal hopper part 1 and the anti - shedding small coal hopper 2 with reinforcing ribs are circular. However, the present utility model is not limited to this, but other forms of anti - shedding coal hoppers with reinforcing ribs can also be used, such as an anti - shedding coal hopper with reinforcing ribs having a square cross - section, that is, the cross - sections of both the upper coal hopper part and the anti - shedding small coal hopper with reinforcing ribs are square.

[0056] Second Embodiment

[0057] According to the present utility model, the anti - shedding coal hopper with reinforcing ribs can also adopt such a form: the cross - section of the upper coal hopper part is square, while the cross - section of the anti - shedding small coal hopper with reinforcing ribs is circular, and a transition connection part is provided therebetween, as Figures 6 - 8 shown, where Figure 6 is a perspective view of the anti - shedding coal hopper with reinforcing ribs of the second embodiment, Figure 7 is a front view of the anti - shedding coal hopper with reinforcing ribs of the second embodiment, and Figure 8 is a bottom view of the anti - shedding coal hopper with reinforcing ribs of the second embodiment.

[0058] Please refer to Figure 6, the upper coal hopper part 101 has a square cross-section, and the anti-dropping small coal hopper 102 with reinforcing ribs has a circular cross-section. The two are connected to each other through a transition connecting part 191. The upper opening of the transition connecting part 191 is square, and the lower opening is circular. During assembly, the upper opening of the transition connecting part 191 is butted against the lower end part of the upper coal hopper part, and the lower opening of the transition connecting part 191 is butted against the uppermost frustum of the anti-dropping small coal hopper with reinforcing ribs. The butted part is connected by means such as welding.

[0059] Adjacent frustums 103 of the anti-dropping small coal hopper 102 with reinforcing ribs are connected to each other by means such as welding, thereby forming the anti-dropping small coal hopper main body with reinforcing ribs.

[0060] Reinforcing ribs 109 are provided on the anti-dropping small coal hopper 102 with reinforcing ribs. The number of the reinforcing ribs 109 is not limited and can be selected according to the actual application scenario. In the illustrated embodiment, four reinforcing ribs 109 are adopted. When the number of the reinforcing ribs 109 is multiple, the reinforcing ribs 109 are arranged at intervals in the circumferential direction.

[0061] Continue to refer to Figures 6 - 8 , the reinforcing rib 109 is in the shape of a strip plate. In the assembled state, its plate surface fits against the outer surface of the anti-dropping small coal hopper main body with reinforcing ribs, and is fixedly connected at the fitting part by means such as welding. The reinforcing rib 109 extends in the up-and-down direction on the outer surface of the anti-dropping small coal hopper main body. The lower end part extends past the connecting part of the lowermost two frustums and is located between the longitudinal ends of the lowermost frustum. The upper end part extends upward through the transition connecting part 191 and extends beyond the transition connecting part 191 for connecting with the transition connecting part 191 and the lower end of the upper coal hopper part 101. The reinforcing rib 109 fits against the outer surfaces of the transition connecting part 191 and the lower end of the upper coal hopper part 101 and is connected by means such as welding. As a preferred technical solution, the upper end part of the reinforcing rib 109 extends upward through the flat part 150 of the transition connecting part 191, thereby enabling the plate surface of the reinforcing rib 109 to fit more tightly against the outer surface of the transition connecting part 191.

[0062] As a preferred solution, in order to strengthen the connection strength between each frustum and the connection strength between the uppermost frustum and the transition connection part 191, a reinforcing hoop 107 can be provided at the connection between two adjacent frustums and / or a reinforcing hoop 117 can be provided at the connection between the uppermost frustum and the transition connection part 191. The reinforcing hoop is welded to the frustum or the transition connection part at the upper and lower longitudinal ends. Preferably, the reinforcing hoops 7 and 17 are arranged below the reinforcing ribs 9. In addition, as another alternative solution, the reinforcing hoop can also be provided only at the connections between adjacent frustums in the upper part of the anti-falling small coal hopper body with reinforcing ribs and at the connection between the uppermost frustum and the transition connection part 191, while no reinforcing hoop is provided at the connections between adjacent frustums in the lower part of the anti-falling small coal hopper body with reinforcing ribs.

[0063] As a preferred solution, a reinforcing hoop (not shown in the figure) can be provided at the connection part between the upper coal hopper part 101 and the transition connection part 191. Preferably, when the reinforcing hoop is provided, the reinforcing hoop is arranged below the reinforcing rib 9.

[0064] In addition, in order to reinforce the connection strength between the upper coal hopper part 101 and the transition connection part 191, as a preferred solution, as Figure 9 shown, a reinforcing plate 108 can be provided at the connection part between the upper coal hopper part 101 and the transition connection part 191. The reinforcing plate 108 extends in the up and down direction, and its plate surface substantially coincides with the lower end of the upper coal hopper part 101 and the outer surface of the transition connection part 191. The upper plate surface is attached to the lower end surface of the upper coal hopper part 101, and the lower plate surface is attached to the outer surface of the transition connection part 191, and they are connected by means such as welding.

[0065] By taking measures such as providing reinforcing hoops and reinforcing plates, the connection strength of the anti-falling small coal hopper with reinforcing ribs itself and the connection strength between the upper coal hopper part 101, the transition connection part 191 and the anti-falling small coal hopper 102 with reinforcing ribs are further improved.

[0066] In the solution described above, the upper end part of the reinforcing rib 109 extends beyond the transition connection part 191. As an alternative technical solution, the upper end part of the reinforcing rib 109 may not extend beyond the transition connection part 191, but be located between the longitudinal two ends of the transition connection part 191, as Figure 10 shown. As another alternative technical solution, the upper end part of the reinforcing rib 109 may not extend beyond the anti-falling small coal hopper with reinforcing ribs, but be located between the longitudinal two ends of, for example, the uppermost frustum. In addition, the connection strength between the transition connection part 191 and the anti-falling small coal hopper 102 with reinforcing ribs can also be improved by using a reinforcing plate.

[0067] In addition, as an alternative technical solution, the reinforcing rib 109 does not have to extend over the entire length of the anti-falling small coal hopper 102 with reinforcing ribs. Instead, the longitudinal length of the reinforcing rib 9 can be shortened, and it can be arranged only at the positions of the upper conical frustum sections of the anti-falling small coal hopper 102 with reinforcing ribs that are subjected to greater stress.

[0068] In the technical solution described above, the reinforcing rib 109 is arranged to extend in the vertical direction along the outer surfaces of the main body of the anti-falling small coal hopper with reinforcing ribs, the transition connecting portion 191, and the lower end of the upper coal hopper portion. However, the present invention is not limited thereto, and the reinforcing rib 109 can also be arranged to extend spirally on the said outer surface.

[0069] Third Embodiment

[0070] In the first embodiment described above, the anti-falling coal hopper with reinforcing ribs includes an upper coal hopper portion located at the upper part and an anti-falling small coal hopper with reinforcing ribs located between the upper coal hopper portion and the slide gate. The third embodiment of the present application relates to the first form of the anti-falling coal hopper with reinforcing ribs, that is, the entire coal hopper is assembled by splicing multiple conical frustums of equal or unequal heights. The structure of the anti-falling coal hopper with reinforcing ribs in the third embodiment is the same as that of the anti-falling small coal hopper with reinforcing ribs in the anti-falling coal hopper with reinforcing ribs in the first embodiment, and its description is omitted for simplicity. The only difference is that in use, the upper end of the anti-falling coal hopper with reinforcing ribs in the third embodiment is connected to the lower end of the coal hopper main body.

[0071] Fourth Embodiment

[0072] The following combines Figure 11 to describe the fourth embodiment of the present invention. Usually, as Figure 11 shown, the coal delivery system includes at least two coal delivery devices. Figure 11 The situation where the coal delivery system includes two coal delivery devices is shown, that is, the coal delivery device 200 and the coal delivery device 300. Each coal delivery device includes a coal hopper 53 and a coal feeder 55 arranged below the coal hopper. In recent years, separate bin coal distribution has been increasingly widely used in this field. The so-called separate bin coal distribution means that the coal bin of a coal delivery device is configured to supply coal to its own coal feeder and also to the coal feeder of an adjacent coal delivery device through a coal diversion system. Thus, the adjacent coal delivery device can either convey the first type of coal stored in its own storage through its own coal feeder to the corresponding unit or obtain the second type of coal diverted and distributed by the said one coal delivery device and convey it to the corresponding unit through its own coal feeder, thereby realizing the switching between two working conditions.

[0073] In order to achieve coal batching in separate bins, a coal material diversion system is provided between a coal material distribution device and an adjacent coal material distribution device, enabling a coal material distribution device to divert and supply coal to an adjacent coal material distribution device. In Figure 11 the illustrated embodiment, the coal material distribution device 200 is configured to divert and supply coal to the adjacent coal material distribution device 300. As Figure 11 shown, the coal material diversion system includes a diversion coal hopper 56 connected to the coal bin of the coal material distribution device 200 (hereinafter simply referred to as the diversion coal bin in the following and other parts of this application), a diversion coal feeder 57, and a connecting pipe 59 for connecting the outlet 58 of the diversion coal feeder to the coal feeder 55 of the coal material distribution device 300.

[0074] Continuing to refer to Figure 11 , the diversion coal hopper 56 is connected to the diversion coal bin. In the illustrated embodiment, the diversion coal hopper 56 is connected to the coal hopper 53 of the diversion coal bin, so that the diversion coal hopper and the diversion coal bin are interconnected, and the coal material in the diversion coal bin can be obtained. The diameter of the diversion coal hopper 56 gradually decreases from top to bottom, with the upper end being the coal inlet port and the lower end being the coal outlet. In the illustrated embodiment, the main body of the diversion coal hopper includes a connecting portion 66 connected to the coal hopper 53 of the diversion coal bin and multiple stacked frustums 67. The adjacent frustums are connected to each other, and the uppermost frustum is connected to the connecting portion. The coal inlet port of the diversion coal hopper 56 is docked with the coal outlet of the coal hopper 53 of the diversion coal bin, and the diversion coal hopper 56 is fixedly connected to the coal hopper 53 by means such as welding.

[0075] For the diversion coal hopper 56, the same reinforcement structure as described in connection with the first to third embodiments above can be adopted to improve the connection strength. For the sake of simplicity, its description is omitted.

[0076] The present invention has been described above with reference to the accompanying drawings in conjunction with specific embodiments, but this is only for the purpose of illustration, and the present invention is not limited thereto. Therefore, it is obvious to those skilled in the art that various changes and modifications can be made within the technical spirit and scope of the present invention, and these changes and modifications should also be understood to fall within the scope of the present invention. The scope of the present invention is defined by the claimed technical solution and its equivalent solutions.
