Description

Technical Field

[0001] This application belongs to the field of mineral transportation technology, specifically relating to a screening and crushing system with multi-point unloading function. Background Technology

[0002] In underground mining operations, the typical process involves the following steps: coal cutting by the mining machine – transport by scraper conveyor at the mining face – transfer by transshipment conveyor – transport by conveyor belt in the roadway – transport by main conveyor belt – buffering in the underground coal bunker – transport to the surface by hoisting belt. Some coal mines, to accommodate the needs of fully mechanized mining faces, multiple tunneling faces, or due to unsuitable underground geological conditions, design two or more underground coal bunkers. At the underground coal bunker, to control particle size, most coal mines design roller crushers for pre-crushing before the coal enters the bunker. However, the crushing of all raw coal by the crusher results in the breaking of large pieces of coal, while small pieces are also broken into fine coal and powder, leading to a loss of lump coal ratio.

[0054] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0055] See also Figure 1-11 As shown, an embodiment of this application provides a screening and crushing system with multi-point unloading function, comprising:

[0056] The tank 1 has a baffle 11 inside, which divides the inside of the tank 1 into a first channel and a second channel; the tank 1 includes a crushing section 12 and at least one screening section 13.

[0057] Drive component 2, which is disposed on the groove 1 and located on both sides of the baffle 11;

[0058] The transport component 3 passes through the first channel and the second channel and is connected to the transmission component. The transport component 3 can drive the material entering the tank 1 to move.

[0059] At least one of the hoppers 4 is located at the bottom of the tank;

[0060] When the transport component 3 moves within the first channel, it carries the material screened by the screening section 13 into the crushing section 12.

[0061] When the transport component 3 moves within the second channel, it can move the material after passing through the crushing section 12 and the screening section 13 and feed it into the hopper 4.

[0062] Specifically, the first channel is the material transport channel formed above the trough 1 and the baffle 11, and the second channel is the material transport channel formed below the trough 1 and the baffle 11. The feeder 5 can transport and feed the material into the first channel inside the trough 1. When the drive component 2 drives the carrier component 3 to move inside the first channel of the trough 1, it can first scrape the material and feed it into the screening section 13. The screening section 13 can screen the material, and small particles fall directly into the second channel. The screening section 13 can screen the material fed into the trough 1, and the screened small particles fall directly into the second channel without crushing, avoiding excessive crushing of the material. Taking coal as an example, excessive crushing will reduce its lump coal rate and affect its selling value. The remaining large particles after screening section 13 enter crushing section 12, where the material is crushed to reduce its particle size. After crushing, the material is fed into the second channel of tank 1 by the conveyor component 3, and the conveyor component 3 continues to move it in the second channel to the silo 4 for storage. Crushing section 12 crushes the larger particles and then stores them in silo 4. The crushed coal particles can be more compactly packed in silo 4, and the same volume of storage space can hold more coal, increasing the storage capacity.

[0063] Among them, the screening section 13 on the tank 1 can be multiple sections or one section. When the screening section 13 is multiple sections, it can be distributed at intervals or continuously on the tank 1.

[0064] The crushing section 12 on the tank 1 can be multiple sections or a single section. When the crushing section 12 is multiple sections, it can be distributed at intervals or continuously on the tank 1. As the most preferred embodiment, the crushing section 12 is located behind the screening section 13, which can ultimately achieve the crushing of large particles after screening.

[0065] The number of silos 4 can be one or more, and they are constructed according to the actual storage needs. When multiple silos 4 are located at the bottom of the tank 1, materials can be put into any silo 4 and stored sequentially. Multiple silos can increase the storage capacity, and coal can also be classified and stored according to its quality.

[0066] The screening section 13 includes:

[0067] Screening trough 131, the baffle 11 is disposed inside the screening trough 131;

[0068] The screening plate 132 has a first mounting hole on the baffle 11, and the screening plate 132 is detachably installed in the first mounting hole. The screening plate 132 has a plurality of material leakage holes 133.

[0069] Specifically, each screening section 13 includes a screening trough 131 and a screening plate 132. The installation of the baffle 11 forms a first channel and a second channel in the screening trough 131. The screening plate 132 is installed in the first mounting hole of the baffle 11. When the material passes through the screening plate 132 under the drive of the conveying component 3, the material smaller than the discharge hole 133 will fall into the second channel through the discharge hole 133, thereby realizing the screening of the material and avoiding excessive crushing of small particles.

[0070] The screening plate 132 is detachably installed in the first mounting hole, which facilitates the disassembly and replacement of the screening plate 132 and makes it convenient for maintenance.

[0071] Alternatively, the screen plate 132 can be replaced to allow for the replacement of material leakage holes 133 of different sizes.

[0072] The screening plate 132 is detachably installed in the first mounting hole. An insertion hole is provided on one side of the screening trough 131, through which the screening plate 132 is inserted into the screening trough 131. A stepped structure is provided on the side wall of the first mounting hole of the baffle 11, and a matching stepped structure is provided at the contact end of the screening plate 132 with the side wall of the first mounting hole, allowing the installed screening plate 132 to overlap with the baffle 11 for stronger fixation. Furthermore, the baffle 11 and the upper side of the screening plate 132 form a plane, facilitating material movement. A first connecting plate is also installed on the outside of the screening trough 131, which can be fixedly connected to the screening plate 132 with bolts, facilitating disassembly while fixing and limiting the position of the installed screening plate 132.

[0073] The broken segment 12 includes:

[0074] Crushing trough 121, the baffle 11 is disposed inside the crushing trough 121;

[0075] The crushing device 122 is disposed opposite to the crushing trough 121, and the output end of the crushing device 122 is located above the baffle 11 inside the crushing trough 121.

[0076] Specifically, each crushing section 12 includes a crushing trough 121 and a crushing device 122. A baffle 11 is installed in the crushing trough 121 to divide it into a first channel and a second channel. After passing through the screening plate 132, large particles of material enter the first channel of the crushing trough 121 under the drive of the conveying component 3. The crushing end of the crushing device 122 can crush the large particles of material.

[0077] There are two crushing devices 122, which are distributed opposite each other on the crushing trough 121. The crushing device 122 is a twin-shaft crusher. Its output end forms a space of different heights with the baffle 11 by rotating, so as to crush the material.

[0078] The material crushed by the crushing section 12 enters the second channel and is fed into any silo 4 by the conveying component 3. This means that one set of crushing device 122 can meet the feeding and crushing needs of multiple silos 4. Compared with the existing technology where each silo needs to be equipped with a set of crushing devices, this not only reduces the number of crushing devices used, but also greatly reduces the consumption of electricity.

[0079] The broken section 12 also includes:

[0080] A reinforcing plate 123 is disposed on the baffle 11, and the reinforcing plate 123 is matched with the output end position of the crushing device 122.

[0081] Specifically, the reinforcing plate 123 can replace the baffle 11 and is installed at the matching position of the output end of the crushing device 122. The reinforcing plate 123 adopts a thickened and reinforced design. After installation, its upper wall surface is flush with the upper wall surface of the baffle 11, which can cooperate with the output end of the crushing device 122 to crush materials. The reinforcing plate 123 can also be installed below the baffle 11 and matched with the output end of the crushing device 122 to support the baffle 11 and reduce the probability of deformation of the baffle 11 when the crushing device 122 crushes materials. Moreover, the two sides of the reinforcing plate 123 are connected to the side walls of the crushing trough 121, further improving the fixing ability of the baffle 11.

[0082] The crushing section 12 also includes: a coal cleaning plate 124;

[0083] The coal cleaning plate 124 is disposed on the side of the crushing trough 121 away from the screening trough 131. The baffle 11 has a discharge hole, which is located between the coal cleaning plate 124 and the output end of the crushing device 122.

[0084] Specifically, the coal cleaning plate 124 is installed on the crushing trough 121 and is set perpendicular to the baffle 11. It can block the crushed material and prevent it from entering the drive section 15. Moreover, the baffle 11 between the crushing device 122 and the coal cleaning plate 124 has a discharge hole. The discharge hole is an open design, that is, there is a certain gap between the baffle 11 and the discharge plate, which ensures that all the crushed material can fall from the discharge hole into the second channel.

[0085] The tank 1 further includes at least one unloading section 14, the unloading section 14 comprising:

[0086] The discharge chute 141, and the baffle 11 is disposed inside the discharge chute 141;

[0087] The unloading plate 142 has a second mounting hole on the baffle 11, and the unloading plate 142 is detachably installed in the second mounting hole.

[0088] Specifically, each unloading section 14 includes an unloading trough 141 and an unloading plate 142. A baffle 11 is installed in the unloading trough 141 to divide it into a first channel and a second channel. A second mounting hole is provided on the baffle 11 located in the unloading trough 141. The unloading plate 142 is detachably installed in the second mounting hole. In use, in the first channel, the transport component 3 drives the material to move and conveys the material to the screening section 13 to achieve screening. In the second channel, the crushed material is transported to the corresponding hopper 4.

[0089] The unloading plate 142 is detachably installed in the second mounting hole, which facilitates the disassembly and replacement of the unloading plate 142 and makes it convenient for maintenance.

[0090] The unloading plate 142 is detachably installed in the second mounting hole. An insertion hole is provided on one side of the unloading trough 141, through which the unloading plate 142 is inserted into the unloading trough 141. A stepped structure is provided on the side wall of the second mounting hole of the baffle 11, and a matching stepped structure is provided at the contact end of the unloading plate 142 with the side wall of the second mounting hole. This allows the installed screening plate 132 to overlap with the baffle 11, ensuring strong and stable fixation. Furthermore, the baffle 11 and the upper side of the unloading plate 142 form a plane, facilitating material movement. A second connecting plate is also installed on the outside of the unloading trough 141. The second connecting plate can be fixedly connected to the unloading plate 142 by bolts, facilitating disassembly while fixing and limiting the position of the installed unloading plate 142.

[0091] Each unloading section 14 of the tank body 1 is provided with a hopper 4 at the bottom;

[0092] The hopper 4 includes: a hopper body 41 and a discharge valve 42;

[0093] The silo body 41 has a storage space inside, the bottom of the tank body 1 has a discharge port, the discharge valve 42 is located in the discharge port, and the discharge valve 42 is connected to the silo body 41.

[0094] Specifically, the hopper 4 can be set at the bottom of each unloading section 14 or on the driven section 17 of the tank body 1. Therefore, the number of hoppers 4 can be set to multiple according to the usage requirements. The hopper 4 includes a hopper body 41 and an unloading valve 42. The hopper body 41 has a storage space for placing materials. The unloading valve 42 is installed in the unloading port opened at the bottom of the tank body 1. The setting of multiple hoppers 4 allows for selective storage of materials. When the unloading valve 42 on the target hopper 4 is opened, the materials can be moved into the target hopper 4 during the process of the transport component 3 moving the materials in the second channel, thus realizing flexible storage.

[0095] In particular, a hopper 4 is generally installed at the bottom of the unloading section 14. When the equipment malfunctions, the unloading plate 142 can be removed from the unloading trough 141, and the unloading valve 42 of the bottom hopper 4 can be opened so that the material can be directly put into the hopper 4, which facilitates the unloading of the material inside the trough 1 and the maintenance of the equipment.

[0096] The unloading valve 42 is controlled by an electro-hydraulic control system. Operators can input commands to automatically open and close the valve, making it convenient and safe to use. Furthermore, the speed of material unloading can be controlled by adjusting the opening and closing of the valve 42.

[0097] The tank 1 further includes: a driving section 15, a connecting section 16 and a driven section 17. The driving section 15 is connected to the crushing section 12. The screening section 13 is connected to the side of the crushing section 12 away from the driving section 15. The unloading section 14 is connected to the screening section 13 and the driven section 17 by the connecting section 16.

[0098] The drive segment 15 includes a drive slot;

[0099] The driven section 17 includes a driven groove;

[0100] The connecting segment 16 includes at least one connecting groove, and the baffle 11 is disposed within the connecting groove.

[0101] Specifically, the connecting section 16 is used to connect the unloading section 14 and the screening section 13. It can also connect multiple screening sections 13 or multiple unloading sections 14. Different combinations of the crushing section 12, screening section 13 and unloading section 14 can be achieved through the setting of the connecting section 16.

[0102] The driving component 2 includes:

[0103] The second driving device 21 is disposed in the driving groove;

[0104] A drive sprocket 22 is rotatably disposed in the drive groove, and the drive sprocket 22 is connected to the output end of the second drive device 21;

[0105] The driven sprocket 23 is disposed in the driven groove.

[0106] Specifically, after the transport component 3 is installed on the outside of the drive sprocket 22 and the driven sprocket 23, the second drive device 21 drives the drive sprocket 22 to rotate, which can drive the transport component 3 to move back and forth in the first channel and the second channel of the tank 1, and can continuously drive the material to move in the tank. The material can be crushed and then driven to be stored in any hopper 4, making it more convenient to use.

[0107] The transport component 3 is a chain scraper, and the transport component 3 is disposed on the outside of the drive sprocket 22 and the driven sprocket 23.

[0108] Specifically, the transport component 3 installed in the tank 1 can be a single transport bar or multiple transport bars, and more specifically, the transport component 3 can be a chain scraper.

The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
