Description

Technical Field

[0001] The present application relates to the technical field of underground coal mine filter stations, and in particular to a flow channel structure of a coal mine filter station. Background Art

[0002] The backwash filter station is a filtering device used in the fluid supply system of underground fully-mechanized mining equipment such as coal mines. Backwashing can intercept, filter and remove pollutants in the hydraulic fluid in the hydraulic system, thereby ensuring the normal operation of various hydraulic components of fully-mechanized mining equipment such as hydraulic supports and scraper conveyors in harsh underground environments.

[0003] As an important component of the backwash filter station, the structure and layout of the filter module flow channel also affect the integration of the entire filter station. In the related technology, after each inlet control valve core assembly and filter element are assembled to the valve body, its inlet flow channel and outlet flow channel are often designed accordingly, which not only increases the difficulty of designing and molding the valve body, but also makes the valve body less versatile and the overall structure complex, making it difficult to meet the use requirements when limited by different space sizes underground. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, an embodiment of the utility model proposes a flow channel structure of a coal mine filter station, which can meet the liquid inlet of all liquid inlet control valves and the liquid outlet of all filter elements in the same filter module, and the liquid inlet and the liquid outlet can be directly swapped as needed according to the actual layout of the filter module underground. The two are highly interchangeable. At the same time, the design and molding difficulty of the flow channel in the valve body is reduced, the versatility of the valve body is improved, and the overall structure is simple.

Compared with the related art that each liquid inlet control valve and filter element need to be designed with corresponding flow channels respectively, the paired supply and collection channels in the present application realize the separate integration of multiple liquid inlet flow channels and multiple liquid outlet flow channels in the same filter module, which not only reduces the difficulty of flow channel design and molding, but also simplifies the flow channel structure. The overall structure of the valve body is simple. At the same time, since the paired supply and collection channels are adjacently arranged at the same height and have the same structure, the two paired supply and collection channels can be directly swapped with each other as needed during actual use.

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0025] like Figure 1 As shown, a flow channel structure of a coal mine filter station according to an embodiment of the utility model includes a liquid supply and collection channel 1, a liquid inlet channel 2 and a liquid outlet channel 3.

[0026] Among them, there is at least one pair of supply and confluence liquid channels 1 and both extend along the first direction, multiple supply and confluence liquid channels 1 are arranged at intervals at the same height along the second direction and the two ends are flush, the second direction is perpendicular to the first direction, and in the two pairs of supply and confluence liquid channels 1, one supply and confluence liquid channel 1 is connected to the liquid inlet end of the filter element through the liquid inlet control valve of the filter module, and the other supply and confluence liquid channel 1 is connected to the liquid outlet end of the filter element.

[0027] The liquid inlet channel 2 is connected to one of the two ends of one of the liquid supply and liquid confluence channels 1 in each pair of liquid supply and liquid confluence channels 1 , and the liquid outlet channel 3 is connected to one of the two ends of the other liquid supply and liquid confluence channel 1 in each pair of liquid supply and liquid confluence channels 1 .

[0028] According to the flow channel structure of the coal mine filter station in the embodiment of the utility model, the liquid inlet flow channel connected to each liquid inlet control valve and the liquid outlet flow channel connected to the liquid outlet end of each filter element in each filter module are respectively integrated into a supply and collection channel 1. Compared with the related art that each liquid inlet control valve and filter element need to be designed with corresponding flow channels respectively, the paired supply and collection channels 1 in the present application realize the separate integration of multiple liquid inlet flow channels and multiple liquid outlet flow channels in the same filter module, which not only reduces the difficulty of flow channel design and molding, but also simplifies the flow channel structure. The overall structure of the valve body 4 is simple. At the same time, since the paired supply and collection channels 1 are adjacently arranged at the same height and have the same structure, the two paired supply and collection channels 1 can be directly swapped with each other as needed during actual use, and the two are highly interchangeable, thereby improving the versatility of the valve body 4.

[0029] It should be noted that since the paired supply and confluence liquid channels 1 can be used interchangeably, according to the actual layout of the filtration module underground, the corresponding supply and confluence liquid channels 1 are selected to be connected to the emulsion source to be filtered and the liquid supply system of the underground comprehensive mining equipment respectively based on the principle of convenient installation or proximity, among which the supply and confluence liquid channel 1 connected to the emulsion source to be filtered forms a liquid inlet flow channel, and the supply and confluence liquid channel 1 connected to the liquid supply system of the underground comprehensive mining equipment forms a liquid outlet flow channel.

[0030] Specifically, the inner diameters of the two supply and confluence liquid channels 1 in a pair are equal, or the inner diameters of all supply and confluence liquid channels 1 are equal.

[0031] like Figure 1 As shown, in some embodiments, the flow channel structure of the coal mine filter station also includes a valve body 4 and a plug 5. The valve body 4 extends along a first direction and is provided with a liquid supply and confluence channel 1. When one end of the liquid supply and confluence channel 1 is connected to the liquid inlet channel 2 or the liquid outlet channel 3, the plug 5 is fitted in the other end of the liquid supply and confluence channel 1 to seal the end opening of the liquid supply and confluence channel 1.

[0032] The liquid supply and confluence channel 1 is directly opened in the valve body 4, which reduces the processing difficulty of the liquid supply and confluence channel 1. At the same time, the end opening can be directly connected to the liquid inlet channel 2 or the liquid outlet channel 3, and there is no need to design other structures on the valve body 4 to achieve matching connection between the aforementioned channels, thereby simplifying the entire flow channel structure. The method of sealing the idle end opening in the liquid supply and confluence channel 1 with the plug 5 can ensure the normal operation of the filter module and further reduce the hydraulic components on the valve body 4.

[0033] like Figure 1 As shown, in some embodiments, the valve body 4 has one, and the valve body 4 is also provided with a plurality of pairs of liquid supply and collection channels 1.

[0034] Alternatively, there are multiple valve bodies 4, and each valve body 4 is provided with at least one pair of liquid supply and collection channels 1.

[0035] When the valve body 4 is provided with multiple pairs of liquid supply and collection channels 1, multiple filter modules can be integrated on the same valve body 4 to meet the liquid inlet and outlet requirements of multiple filter modules, or the filtering processing capacity of a filter module can be increased. When there are multiple valve bodies 4, multiple filter modules are formed separately, and can meet the use requirements through flexible combination of a corresponding number of filter modules according to the use requirements downhole.

[0036] Specifically, a plurality of pairs of liquid supply and sink channels 1 may be arranged in sequence and spaced apart along the second direction.

[0037] like Figure 1 As shown, in some embodiments, there are multiple valve bodies 4, and the multiple valve bodies 4 are arranged in sequence along the second direction with both ends flush.

[0038] Designing multiple valve bodies 4 to have the same length specification not only improves the regularity of the filter station composed of multiple filter modules, but also facilitates multiple valve bodies 4 to use the same liquid inlet channel 2 for liquid inlet and the same liquid outlet channel 3 for liquid outlet.

[0039] Specifically, in order to further facilitate the use of the same liquid inlet channel 2 for liquid intake and the same liquid outlet channel 3 for liquid discharge between multiple valve bodies 4, and to reduce the setting of intermediate components when the liquid supply and liquid collection channel 1 is connected with the liquid inlet channel 2 and the liquid outlet channel 3, multiple valve bodies 4 can all be provided with liquid supply and liquid collection channels 1 along the first direction.

[0040] like Figure 1 As shown, in some embodiments, the liquid inlet channel 2 and the liquid outlet channel 3 each include a main channel 21 and a sub-channel 22 that are connected to each other, and the sub-channel 22 is connected to one of the two ends of the liquid supply and sink channel 1.

[0041] The main channel 21 is provided with at least two openings 211 , and the openings 211 are connected to a source of emulsion to be filtered or to a liquid supply system of underground fully mechanized mining equipment.

[0042] like Figure 1 As shown, in some embodiments, the flow channel structure of the coal mine filtration station also includes a liquid inlet multi-channel 6 and a liquid outlet multi-channel 7, and the liquid inlet multi-channel 6 and the liquid outlet multi-channel 7 are arranged on both sides of the liquid supply and collection channel 1 along the first direction, and the liquid inlet multi-channel 6 and the liquid outlet multi-channel 7 are both provided with a main channel 21, and the main channel 21 extends along the second direction.

[0043] At least two openings 211 are arranged on the main channel 21, and according to the spatial position of the emulsion source to be filtered and the liquid supply system of the comprehensive mining equipment, the opening 211 that is closest to or more conveniently connected to the liquid inlet multi-port 6 or the liquid outlet multi-port 7 can be selected for connection, thereby effectively improving the flexibility and rationality of connecting the filter station using this flow channel structure with the emulsion source to be filtered and the liquid supply system of the comprehensive mining equipment underground.

[0044] Specifically, the liquid inlet multi-port 6 and the liquid outlet multi-port 7 are arranged on both sides of the valve body 4 along the first direction.

[0045] like Figure 1 As shown, in some embodiments, the liquid inlet multi-way 6 and the liquid outlet multi-way 7 both extend along the second direction.

[0046] The liquid inlet multi-port 6 and the liquid outlet multi-port 7 are arranged on both sides of the liquid supply and liquid collection channel 1 along the first direction, and both are extended along the second direction. Liquid can be directly fed into or discharged from the liquid supply and liquid collection channels 1 of each filter module from both sides, the structural layout is more reasonable, and the filter station has a high degree of integration.

[0047] like Figure 1 As shown, in some embodiments, the flow channel structure of the coal mine filtering station further includes a pipeline 8 and a valve 9. The pipeline 8 is provided with a sub-channel 22. The valve 9 is connected to the pipeline 8 and is used to control the opening and closing of the sub-channel 22.

[0048] The opening and closing of the passage 22 can be controlled by valve 9 to realize the time-sharing maintenance or operation of each filter module in the filter station, so as to complete the maintenance of the filter module without stopping the machine, and ensure the filtration supply of the emulsion required by the liquid supply system of the underground comprehensive mining equipment during the maintenance process, thereby improving the efficiency of comprehensive mining work.

[0049] Specifically, the pipeline 8 is communicated with the end opening of the liquid supply and confluence passage 1 of the valve body 4 through the SAE flange.

[0050] like Figure 1 As shown, in some embodiments, the sub-channel 22 extends along the first direction and is coaxial with the supply and sink channel 1 .

[0051] The sub-channel 22 and the supply and collection liquid channel 1 are coaxial, and the sub-channel 22 extends in a first direction, and the main channel 21 extends in a second direction. The structural design in which the two are vertically connected shortens the length of the pipeline layout of the filter module and makes the overall layout of the flow channel structure more regular.

[0052] like Figure 1 As shown, in some embodiments, the inner diameters of the liquid supply and collection channel 1, the liquid inlet channel 2, and the liquid outlet channel 3 are equal and their axes are in the same horizontal plane.

[0053] Designing the inner diameters of the liquid supply and collection channel 1, the liquid inlet channel 2 and the liquid outlet channel 3 to be equal can effectively avoid the problem that when the inner diameters are inconsistent, the flow rate of the emulsion in each channel is different, resulting in the change of the emulsion pressure, thereby affecting the normal operation of the entire filtration station. In addition, the axes of the three are in the same horizontal plane, which ensures the universality of the liquid inlet multi-way 6 and the liquid outlet multi-way 7 when the positions are swapped, and avoids the influence of the direct swapping operation of the liquid inlet multi-way 6 and the liquid outlet multi-way 7 when there is a height difference between the channels.

[0054] It should be noted that the emulsion supplied to the liquid inlet control valve by the emulsion source to be filtered through the opening 211, the main channel 21, the sub-channel 22 and the supply and confluence channel 1 is an emulsion with a certain pressure. If the inner diameters of the supply and confluence channel 1, the main channel 21 and the sub-channel 22 are inconsistent, the pressure of the emulsion will be changed when the emulsion flows through the various channels, thereby affecting the opening and closing actions of the liquid inlet control valve or the sewage control valve, making it difficult for the entire filtration station to operate normally.

[0055] Now, in combination with the specific structure of the flow channel structure of the coal mine filter station, its working process is explained. Specifically, according to the actual layout and installation of the filter station underground, combined with the spatial position of the emulsion source to be filtered and the liquid supply system of the comprehensive mining equipment, select the opening 211 that is closest to or more conveniently connected to the liquid inlet multi-way 6 or the liquid outlet multi-way 7 for connection, and then select the corresponding liquid supply and confluence channel 1 nearby to be connected to the liquid inlet multi-way 6 or the liquid outlet multi-way 7 respectively, so as to complete the connection of the entire flow channel structure. During filtering, the emulsion source to be filtered supplies the emulsion to the opening 211 of the liquid inlet multi-way 6, and the emulsion flows along the main channel 21, the sub-channel 22 and one of the paired supply and confluence channels 1 to the liquid inlet control valve, and then enters the liquid inlet end of the filter element, and the emulsion is filtered in the filter element. The filtered emulsion flows out from the liquid outlet end of the filter element, enters the other liquid supply and confluence channel 1 in the paired supply and confluence channels 1, and is supplied to the liquid supply system of the underground comprehensive mining equipment through the sub-channel 22, the main channel 21 and the opening 211 of the liquid outlet multi-way 7.
