[0028] Reference Figures 1 to 6 , an embodiment of the present application provides a liquid storage tank, which may include a tank body 1, multiple sets of sliding components, a filter plate 2, and a driving component. The tank body 1 has a top end and a bottom end oppositely arranged in its own axial direction. A drain pipe 11 is communicatively arranged at the bottom end, and a slag discharge pipe 12 is communicatively arranged on the outer periphery. At least two grooves 13 are arranged on the inner periphery of the tank body 1; multiple sets of sliding components correspond to the respective grooves 13 one by one and are arranged in the corresponding grooves 13, and the sliding components have the freedom to move circumferentially along the tank body 1; the filter plate 2 is obliquely arranged in the tank body 1 and is respectively connected to the respective sliding components. The outer periphery of the filter plate 2 fits with the inner periphery of the tank body 1. Among them, in the axial direction of the tank body 1, the filter plate 2 is corresponding to the slag discharge pipe 12 near the bottom end and is located on the side of the slag discharge pipe 12 near the bottom end; the driving component is arranged on the tank body 1 and is connected to a set of sliding components, and the driving component drives the corresponding sliding component to reciprocate along the axial direction of the tank body 1.

[0029] A liquid storage tank proposed in an embodiment of the present application. Impurities in the liquid are blocked by the filter plate 2. When the drain pipe 11 drains the liquid, only the clear liquid is discharged, which is convenient to use. The filter plate 2 is inclined and is located on one side of the slag discharge pipe 12 near the bottom end at the bottom. In this way, when the impurities are on the inclined filter plate 2, they will converge towards the slag discharge pipe 12, which is convenient for discharging the impurities at one time by opening the slag discharge pipe 12 after the liquid discharge is completed. The filter plate 2 is connected to the sliding assembly, so that the filter plate 2 also has the freedom to move axially along the tank body 1. Then, the driving assembly drives the sliding assembly and the filter plate 2 to reciprocate axially along the tank body 1, so that the filter plate 2 vibrates, which is convenient for driving the impurities attached to the filter plate 2 to converge towards the slag discharge pipe 12, making it more convenient to use.

[0030] For example, when using this liquid storage tank, the axis of the tank body 1 can be the same as the direction of gravity. At this time, the bottom end and the top end of the tank body 1 are the lower and upper parts of the tank body 1 respectively. The drain pipe 11 is arranged at the lower part of the tank body 1. The drain pipe 11 and the slag discharge pipe 12 are usually in a closed state. When draining the liquid, just open the drain pipe 11. After the solution in the tank body 1 is drained, the slag discharge pipe 12 can be opened to discharge the slag.

[0031] It should be understood that the lowest point of the filter plate 2 is flush with the highest point of the movement in the axial direction of the tank body 1 and the side of the slag discharge pipe 12 facing the bottom end. In this way, it can prevent impurities from bypassing the filter plate 2 through the opening of the tank body 1 at the slag discharge pipe 12.

[0032] It should be noted that the tank body 1 also has a liquid inlet, and the liquid inlet is located at the top or the side wall of the tank body 1.

[0033] In an exemplary embodiment, the bottom end of the tank body 1 is conical and contracts towards the drain pipe 11. In this way, when draining the liquid, the residue of the solution in the tank body 1 can be greatly reduced, and the draining effect is better.

[0034] Reference Figures 2 to 4 , in an exemplary embodiment, the axis of the slag discharge pipe 12 is the same as the radial direction of the tank body 1; there are two grooves 13, and the two grooves 13 are arranged opposite to each other in the first direction, and the first direction is perpendicular to the axis of the tank body 1 and the axis of the slag discharge pipe 12 respectively.

[0035] Specifically, as Figure 3 And Figure 4 shown, the first direction is the X direction. The opposite sides of the filter plate 2 in the first direction are respectively connected to a sliding assembly, and each sliding assembly can slide axially along the tank body 1. In this way, the process of the filter plate 2 sliding axially along the tank body 1 through the two sliding assemblies is more stable.

[0036] Reference Figures 2 to 4, in an exemplary embodiment, the filter plate 2 may include a strip-shaped filter plate 21 and two side filter plates 22. The extending direction of the strip-shaped filter plate 21 is perpendicular to the first direction, and the end close to the slag discharge pipe 12 is located on the side of the slag discharge pipe 12 close to the bottom end. An arc-shaped depression 211 is provided on the side of the strip-shaped filter plate 21 facing the top; the two side filter plates 22 are respectively connected to two sets of sliding components, and the two side filter plates 22 are oppositely arranged on both sides of the strip-shaped filter plate 21 in the first direction.

[0037] Specifically, as Figure 2 shown in Figure 4 , the filter plate 2 includes a strip-shaped filter plate 21 and two side filter plates 22. The extending direction of the strip-shaped filter plate 21 is perpendicular to the first direction, and the two side filter plates 22 are arranged on the opposite sides of the strip-shaped filter plate 21 in the first direction. At the same time, the strip-shaped filter plate 21 and the two side filter plates 22 are both inclined towards the slag discharge pipe 12. It can be understood that the strip-shaped filter plate 21 and the two side filter plates 22 are initially horizontal and located above the slag discharge pipe 12. When the strip-shaped filter plate 21 and the two side filter plates 22 rotate by a certain angle around the first direction, the end of the strip-shaped filter plate 21 close to the slag discharge pipe 12 is located below the slag discharge pipe 12. Among them, the certain angle can be 45°. In this way, the impurities on the strip-shaped filter plate 21 or the side filter plates 22 will roll towards the slag discharge pipe 12.

[0038] Furthermore, the arc-shaped depression 211 on the strip-shaped filter plate 21 can correspond to the slag discharge pipe 12. The arc-shaped depression 211 can be semi-cylindrical, and the radius of the arc-shaped depression 211 is the same as the radius of the slag discharge pipe 12. In this way, it is more convenient for impurities to enter the slag discharge pipe 12 from the arc-shaped depression 211.

[0039] In an exemplary embodiment, the included angle between the two side filter plates 22 is a, and 120° < a < 180°; among them, the two side filter plates 22 approach the top on the side away from each other.

[0040] Specifically, the included angle between the two side filter plates 22 can be 150°. In this way, when impurities move on the side filter plates 22, they will approach the strip-shaped filter plate 21 at the same time. In this way, most of the impurities will enter the arc-shaped depression 211 on the strip-shaped filter plate 21 before reaching the inner circumference of the tank body 1, which is more convenient to be discharged from the slag discharge pipe 12, and will not move on the side filter plates 22 to the inner circumference of the tank body 1 and adhere to the inner circumference of the tank body 1.

[0041] Referring to Figure 4 and Figure 5 , in an exemplary embodiment, chutes 131 are provided on both sides of the groove 13 opposite to each other in the circumferential direction of the tank body 1, and the chutes 131 extend along the axial direction of the tank body 1; the sliding component can include a slider 31 and a connecting block 32. The slider 31 is respectively in sliding fit with the two chutes 131; the connecting block 32 connects the slider 31 and the corresponding side filter plate 22.

[0042] Specifically, the slider 31 is slidably engaged with two sliding grooves 131 at the same time. The connecting block 32 connects the slider 31 and the corresponding side filter plate 22. In this way, the side filter plate 22 can slide in the sliding groove 131 through the connecting block 32 on the slider 31. The sliding groove 131 extends along the axial direction of the tank body 1. In other words, the sliding direction of the slider 31 is the same as the axial direction of the tank body 1.

[0043] Reference Figure 5 and Figure 6 , in an exemplary embodiment, the sliding assembly may further include an annular waterproof cloth 33. The annular waterproof cloth 33 is disposed in the groove 13. The outer periphery of the annular waterproof cloth 33 is connected to the side wall of the groove 13, and the inner periphery of the annular waterproof cloth 33 is connected to the connecting block 32; wherein, the annular waterproof cloth 33 seals the gap between the connecting block 32 and the side wall of the groove 13.

[0044] Specifically, the annular waterproof cloth 33 is made of a flexible material and has a certain deformation ability. In this way, on the premise of sealing the gap between the connecting block 32 and the groove 13, it does not affect the movement of the connecting block 32 through the slider 31 in the axial direction of the tank body 1.

[0045] Reference Figures 4 to 6 , in an exemplary embodiment, the driving assembly may include a motor 41, an incomplete gear 42 and a rack 43. The motor 41 is fixed on the outer periphery of the tank body 1 and the axial direction of the output shaft is perpendicular to the axial direction of the tank body 1. The output shaft of the motor 41 penetrates into the groove 13 and is located on the side of the slider 31 away from the connecting block 32; the incomplete gear 42 is sleeved on the outer periphery of the output shaft of the motor 41 and is located in the groove 13; the rack 43 is fixed on the side of the slider 31 away from the connecting block 32 and extends along the axial direction of the tank body 1, and the rack 43 meshes with the incomplete gear 42.

[0046] Specifically, the outer periphery of the incomplete gear 42 is divided into a continuous first arc segment and a second arc segment. The first arc segment is provided with meshing teeth. In this way, when the incomplete gear 42 rotates one week, the meshing state between the incomplete gear 42 and the rack 43 is switched twice; for example, if the incomplete gear 42 and the rack 43 are initially separated, when the incomplete gear 42 rotates one week, the incomplete gear 42 and the rack 43 change from separation to meshing and then to separation.

[0047] Further, when the incomplete gear 42 rotates and meshes with the rack 43, the incomplete gear 42 drives the rack 43 to rise along the axial direction of the tank body 1, further driving the slider 31, the connecting block 32, the side filter plate 22 and the strip filter plate 21 to rise; when the incomplete gear 42 rotates to separate from the rack 43, the rising components fall back to the lowest position due to their own gravity. At this time, when the incomplete gear 42 continues to rotate and meshes with the rack 43 again, repeating the above process can achieve the reciprocating movement of the side filter plate 22 and the strip filter plate 21 in the axial direction of the tank body 1, achieving the vibration effect and facilitating the impurities to roll to the slag discharge pipe 12.

[0048] Reference Figure 6 , in an exemplary embodiment, the sliding assembly may further include a first spring 34, and the first spring 34 is disposed on the side of the slider 31 facing the top and extends along the axial direction of the tank body 1.

[0049] Specifically, the first spring 34 is always in a compressed state. Thus, when the above-mentioned rising components start to fall back to the lowest position due to their own gravity, the first spring 34 further pushes the slider 31 to fall back, accelerating the falling process and ensuring that when the rack 43 meshes with the incomplete gear 42 again, the rack 43 has fallen back to the lowest position.

[0050] In an exemplary embodiment, the sliding assembly may further include a second spring 35, and the second spring 35 is disposed on the side of the slider 31 facing the bottom and extends along the axial direction of the tank body 1.

[0051] Specifically, the second spring 35 is also in a compressed state. At this time, the lowest position where the rising components move is restricted by the second spring 35 and moves up a certain distance. At the same time, when the rising components fall back, they will swing back and forth in the axial direction of the tank body 1 for a certain time under the influence of the first spring 34 and the second spring 35 until the incomplete gear 42 meshes with the rack 43 again; in this way, the vibration effect of the side filter plate 22 and the strip filter plate 21 can be further improved.

[0052] Further, at this time, only one meshing tooth may be provided on the incomplete gear 42, and only one meshing tooth may be provided on the rack 43, so as to ensure that when the rack 43 vibrates, the incomplete gear 42 can also mesh with the rack 43.

[0053] Among them, the rising components refer to the corresponding rack 43, slider 31, connecting block 32, side filter plate 22 and strip filter plate 21.

[0054] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present application by the same token.
