Apparently, the described embodiments are part of the embodiments of the present utility model, rather than all of them.

They are only for the convenience of describing this embodiment and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to this embodiment.

[0033] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this embodiment, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0034] In this embodiment, unless otherwise clearly specified and limited, the terms "set", "installed", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0035] In the embodiments of the present utility model, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

The first feature being "under", "below" and "beneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.

[0036] The following will describe a filtering device of the present utility model in conjunction with Figure 1 The filtering device includes: a housing 1, a filtering mechanism and a pressure detection mechanism.

[0037] The housing 1 has a feed inlet 11, a discharge outlet 12 and a slag discharge port 13, and the slag discharge port 13 can be switched between an open state and a closed state; the filtering mechanism is arranged inside the housing 1, and one side of the filtering mechanism is respectively communicated with the feed inlet 11 and the slag discharge port 13, and the other side of the filtering mechanism is communicated with the discharge outlet 12; the pressure detection mechanism is used to detect the pressure difference between the feed inlet 11 and the discharge outlet 12, and control the opening and closing state of the slag discharge port 13 according to the pressure difference, that is, the open state and the closed state of the slag discharge port 13.

[0038] Specifically, in the open state of the slag discharge port 13, the accumulated dust residue in the housing 1 can be discharged to ensure the filtering effect of the filtering device. The filtering mechanism exerts a filtering effect. The material entering from the feed inlet 11 is filtered by one side of the filtering mechanism and then moves to the other side, while the unfiltered residue remains on one side of the filtering mechanism and can be discharged through the slag discharge port 13. It can be understood that the feed inlet 11 and the slag discharge port 13 are located on the same side of the filtering mechanism, and the discharge outlet 12 is located on the other side of the filtering mechanism, ensuring that the filtrate obtained after filtration is discharged from the discharge outlet 12, and the remaining solid particles, that is, the residue, are discharged through the slag discharge port 13, which can ensure the filtering effect of the filtering device.

[0039] The pressure detection mechanism can detect the pressure difference between the feed inlet 11 and the discharge outlet 12 in real time, and reflect the filtering ability of the filtering mechanism through the pressure difference. If too much residue accumulates, it will cause the filtering ability of the filtering mechanism to decline, and then cause the pressure difference between the feed inlet 11 and the discharge outlet 12 to continue to increase, affecting the filtering efficiency. Therefore, according to the pressure difference detected by the pressure detection mechanism between the feed inlet 11 and the discharge outlet 12, the residue accumulation situation of the filtering device can be known, so as to provide guidance for the opening time of the slag discharge port 13.

[0040] It can be understood that a threshold value of the pressure difference can be set. When the detected pressure difference reaches this threshold value, it means that there is a blockage in the filtering device and slag discharge operation is required. The foreign matter causing the blockage is discharged through the slag discharge port 13 at the lower end of the housing 1. Of course, the slag discharge port 13 can also be opened regularly for slag discharge.

[0041] It can be seen that a filtering device provided by the present utility model includes: a housing 1, a filtering mechanism, and a pressure detection mechanism. The housing 1 has a feed inlet 11, a discharge outlet 12, and a slag discharge port 13, and the slag discharge port 13 can be switched between an open state and a closed state; the filtering mechanism is arranged inside the housing 1, and one side of the filtering mechanism is respectively communicated with the feed inlet 11 and the slag discharge port 13, and the other side of the filtering mechanism is communicated with the discharge outlet 12; the pressure detection mechanism is used to detect the pressure difference between the feed inlet 11 and the discharge outlet 12, and control the opening and closing state of the slag discharge port 13 according to the pressure difference. The filtering device provided by the present utility model can detect whether there is a blockage in the filtering device according to the pressure difference between the feed inlet 11 and the discharge outlet 12. If a blockage occurs, the slag discharge port 13 is opened for slag discharge, ensuring the filtering efficiency of the filtering device, realizing the maintenance of the filtering device without manual disassembly and inspection, reducing the labor intensity and labor cost of employees, and improving the work efficiency.

[0042] In one embodiment of the present utility model, the filtering mechanism includes: a filter screen 21. The filter screen 21 is arranged inside the housing 1, and the outer side of the filter screen 21 is respectively communicated with the feed inlet 11 and the slag discharge port 13, and the inner side of the filter screen 21 is communicated with the discharge outlet 12. Specifically, the component that plays the filtering role in the filtering mechanism can adopt the filter screen 21. The material moves from the outer side to the inner side of the filter screen 21 under its pressure and is filtered when passing through the filter screen 21. The filtrate moves to the discharge outlet 12 through the inner side of the filter screen 21 and is discharged, while the filter residue remains on the outer side of the filter screen 21 and deposits at the bottom of the housing 1 and is discharged through the slag discharge port 13. Therefore, according to the filtering process of the filter screen 21, the feed inlet 11 is located in the middle of one side of the housing 1, the discharge outlet 12 is located in the upper part of the other side of the housing 1, and the slag discharge port 13 is located at the bottom of the housing 1. It can be seen that under the action of its pressure, the filtrate moves upward and is discharged, while the filter residue deposits at the bottom of the housing 1 under the action of its gravity.

[0043] In one embodiment of the present utility model, the filtering mechanism further includes: a filtering pipeline 22 disposed inside the housing 1. One end of the filtering pipeline 22 close to the slag discharge port 13 is formed with a flow channel communicating the inside and outside of the filtering pipeline 22. The filter screen 21 is disposed in the flow channel. One end of the filtering pipeline 22 close to the discharge port 12 is communicated with the discharge port 12. The filtering pipeline 22 is used to separate the material and the filtrate. The filtering pipeline 22 and the housing 1 form a double-layer nested structure. The space between the filtering pipeline 22 and the housing 1 stores the material. The filter residue is located at the bottom. The inside of the filtering pipeline 22 stores the filtrate and flows to the discharge port 12 from its top. The bottom of the filtering pipeline 22 has a flow channel communicating the inside and outside. The filter screen 21 is disposed in this flow channel, so that the material can only enter the inside of the filtering pipeline 22 through the filter screen 21, ensuring that the filtrate discharged to the discharge port 12 has all been filtered.

[0044] In one embodiment of the present utility model, the filtering device further includes: a first fixing bracket 31 and a second fixing bracket 32. Wherein, one end of the first fixing bracket 31 is fixed inside the housing 1, and the other end of the first fixing bracket 31 is connected to one end of the filtering pipeline 22; one end of the second fixing bracket 32 is fixed inside the housing 1, and the other end of the second fixing bracket 32 is connected to the other end of the filtering pipeline 22. Optionally, the first fixing bracket 31 and the second fixing bracket 32 can be connected to the filtering pipeline 22 through fasteners, or assembly grooves can be machined on the first fixing bracket 31 and the second fixing bracket 32 for fixedly installing the filtering pipeline 22. In short, the first fixing bracket 31 and the second fixing bracket 32 in this embodiment are used to position and fix the filtering pipeline 22 to ensure that it does not shake inside the housing 1.

[0045] In one embodiment of the present utility model, the filtering device further includes: a fixing plate 33 and a lifting member 34. Wherein, the fixing plate 33 is fixed on the filtering pipeline 22; one end of the lifting member 34 is connected to the fixing plate 33, and the other end of the lifting member 34 extends out of the housing 1. The lifting member 34 is used to move the filtering pipeline 22 through the fixing plate 33. Specifically, the fixing plate 33 is fixed at the bottom of the filtering pipeline 22. The filtering pipeline 22 is connected to one end of the lifting member 34 through the fixing plate 33. One end of the lifting member 34 extends out from the top of the housing 1, so that when the filtering pipeline 22 is removed, the filtering pipeline 22 can be lifted out of the housing 1 through the lifting member 34, or the filtering pipeline 22 can be put into the housing 1 from the outside of the housing 1, facilitating the assembly of the filtering pipeline 22.

[0046] In one embodiment of the present utility model, the pressure detection mechanism includes: a first pressure sensor 41 and a second pressure sensor 42. Among them, the first pressure sensor 41 is arranged at the feed inlet 11 for detecting the pressure value of the feed inlet 11; the second pressure sensor 42 is arranged at the discharge outlet 12 for detecting the pressure value of the discharge outlet 12. Specifically, the first pressure sensor 41 and the second pressure sensor 42 respectively monitor the pressures at the feed inlet 11 and the discharge outlet 12, and by comparing the pressure value differences between the first pressure sensor 41 and the second pressure sensor 42 over a period of time, it is thus determined whether there is a blockage phenomenon in the filtering device. As for when the pressure value difference is considered a blockage phenomenon, it is determined by factors such as different filter meshes 21, filter pipelines 22, and material properties, and through multiple tests, a pattern can be summarized.

[0047] In one embodiment of the present utility model, the filtering device further includes: a valve body 5, and the valve body 5 is arranged at the slag discharge port 13 for controlling the open state and the closed state of the slag discharge port 13. By arranging the valve body 5 at the slag discharge port 13, its opening and closing states are thus controlled. Preferably, the valve body 5 can adopt a butterfly valve.

[0048] In one embodiment of the present utility model, the valve body 5 has a valve control unit, and the valve control unit is used to control the valve body 5 to switch between the open state and the closed state at preset time intervals. Specifically, the valve control unit is the structure inside the valve body 5 that controls its opening and closing states, and by setting the opening and closing frequencies, regular slag discharge can be carried out to ensure the filtering device

[0049] In one embodiment of the present utility model, the valve body 5 has a valve control unit, and the valve control unit is electrically connected to the pressure detection mechanism; when the pressure detection mechanism detects that the pressure difference between the feed inlet 11 and the discharge outlet 12 is greater than a preset pressure, the valve control unit controls the valve body 5 to open for slag discharge. Specifically, when the detected pressure difference reaches the preset pressure, it proves that there is a blockage phenomenon in the filtering device, then the valve control unit controls the valve body 5 to open for slag discharge. If the current valve body 5 is in an intermittent opening and closing state, the valve control unit controls the valve body 5 to be in a normally open state until the detected pressure difference is less than the preset pressure, and then it can return to the intermittent opening and closing state or the normally closed state.

[0050] The present utility model also provides a feed pipeline system. The feed pipeline system includes: the filtering device in the above embodiments of the present utility model.

[0051] A feed pipeline system provided by the present utility model, because it includes the filtering device in the above embodiments of the present utility model, thus has the same advantages as above.

Some or all of the modules can be selected according to actual needs to achieve the purpose of the solution of this embodiment. Those of ordinary skill in the art can understand and implement it without creative efforts.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace some of the technical features.
