Description

Technical Field

[0001] The utility model relates to the technical field of positive pressure filters, in particular to a positive pressure filter which is convenient for draining liquid. Background Art

[0002] A positive pressure filter is a device for filtering liquids. It applies pressure to force the liquid through the filter medium to filter out impurities such as solid particles in the liquid.

[0003] The existing positive pressure filter is generally composed of a tank body and supporting legs. A liquid outlet is provided at the lower part of the tank body, and the liquid outlet is connected to a liquid outlet pipe. Since the position of the liquid outlet is relatively low and the supporting legs are a fixed structure and cannot be adjusted, the outlet position of the liquid outlet pipe is relatively low when discharging liquid. If the collection box for the liquid is located at a higher position, it is not convenient to discharge the liquid cleanly, and liquid will remain in the liquid outlet pipe. Furthermore, if the positive pressure filter is placed on a workbench as a whole to increase the height of the liquid outlet, the positive pressure filter will become unstable during operation. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a positive pressure filter which is convenient for draining liquid.

[0005] The technical solution of this utility model is as follows:

[0006] A positive pressure filter for convenient liquid discharge, comprising a tank body and a plurality of supporting legs supporting the tank body, wherein the lower end of the tank body is provided with a liquid outlet pipe, the supporting legs are arranged vertically, and further comprising a base arranged on a reference plane and a plurality of sleeves arranged thereon, the sleeves are arranged vertically and correspond to the supporting legs, and the plurality of supporting legs are all slidably connected in the corresponding sleeves;

[0007] At least one lifting mechanism is provided on the base, which is located inside the multiple sleeves and on one side of the liquid outlet pipe. The upper end of the lifting mechanism is an extension end, which can lift the tank body upward in the vertical direction. The position of the lifting mechanism is adjustable along the direction perpendicular to its axis.

[0008] The tank body and the supporting legs are both arranged on the base, and the multiple supporting legs are inserted and slidably connected in the corresponding sleeves. The tank body and the supporting legs can be lifted upward along the length direction of the cylinder body through the lifting mechanism on the base, so as to achieve the effect of increasing the height of the liquid outlet pipe, which is convenient for the liquid outlet pipe to discharge liquid, and there will be no phenomenon of liquid remaining in the liquid outlet pipe. The lifting mechanism can adjust its position on the base according to the position of the liquid outlet pipe and the direction of the pipe body, and will not interfere with the liquid outlet pipe.

[0009] In order to increase the contact area between the extended end and the tank body and avoid slipping due to a small contact area between the extended end and the tank body, an upper top plate is hinged on the extended end, and the curvature of the upper end surface of the upper top plate is consistent with the curvature of the lower end surface of the tank body.

[0010] In order to prevent the supporting legs from being separated from the sleeve when the lifting mechanism increases the height of the tank body, the ratio of the sleeve height to the maximum stroke that can be achieved by the extended end is 1-2.

[0011] The distance between the lower end surface of the tank body and the base is small, which is not convenient for installing the lifting mechanism. For this reason, an elongated installation groove is opened on the base along the direction of the vertical lifting mechanism axis, and the lower part of the lifting mechanism is connected to the elongated installation groove through an adjustment plate.

[0012] In order to enable the adjustment plate to drive the lifting mechanism to adjust the position in the elongated installation groove, a wooden connecting plate is provided on the upper end surface of the elongated installation groove along its length direction, and the adjustment plate is detachably connected to the wooden connecting plate through a connecting piece.

[0013] In order to ensure that the force on the tank body is relatively uniform when it is lifted, two groups of lifting mechanisms are provided, and the two groups of lifting mechanisms are symmetrically arranged on the long installation groove on both sides along the axis direction of the tank body.

[0014] Regarding the specific structure of the base, the base is provided with a plurality of cross-connected horizontal plates inside, and the wooden connecting plates are detachably connected to the upper end surfaces of the horizontal plates, wherein a group of connected connecting plates and horizontal plates are provided with long installation grooves connected up and down.

[0015] The specific structure of the above-mentioned adjustment plate is that the adjustment plate is an L-shaped plate symmetrically arranged on both sides of the lifting mechanism. A single L-shaped plate includes a long plate and a short plate vertically connected. The short plate is installed on the horizontal plate where the connecting plate is set, and the long plate is installed on the vertical side of the horizontal plate.

[0016] The beneficial effects of the utility model are:

[0017] The supporting legs are located on the base, and the multiple supporting legs are respectively inserted into the corresponding sleeves and slidably connected with the sleeves. The sleeves play a guiding role. Under the action of the lifting mechanism, the tank body can be lifted up to a certain height in the vertical direction, so that the height of the liquid outlet pipe is increased, which is convenient for the positive pressure filter to smoothly discharge the filtered liquid after pressure filtration, and avoid the liquid from being retained in the liquid outlet pipe;

[0018] The base can also improve the stability of the positive pressure filter during operation, avoiding the instability of the tank caused by increased vibration during pressurized filtration.

[0019] The lifting mechanism can adjust its position on the long installation groove according to the position of the liquid outlet pipe and the direction of the pipe body of the liquid outlet pipe, without interfering with the liquid outlet pipe;

[0020] Two sets of lifting mechanisms are symmetrically arranged, which can be extended and retracted synchronously, so as to facilitate the stable lifting of the tank body;

[0021] The connecting plates of the same lifting mechanism are two symmetrically arranged L-shaped plates, which can be snapped onto the corresponding horizontal plates. Even if no connecting parts are provided, the lifting mechanism can be ensured not to tip over, and at the same time, the two lifting mechanisms can be quickly adjusted in the direction of the elongated mounting groove.

[0031] See also Figure 2 and Figure 5As shown, the distance between the lower end face of the tank body 1 and the base 4 is small, which is not convenient for installing the lifting mechanism 6. For this reason, two cross-connected horizontal plates 8 are provided inside the base 4, and the wooden connecting plate 11 is detachably connected to the upper end face of the horizontal plate 8. An elongated mounting groove 81 is provided on one of the horizontal plates 8, and an elongated mounting groove 81 is provided on the base 4 along the direction of the vertical axis of the lifting mechanism 6. In order to make the force on the tank body 1 relatively uniform when it is raised, an adjustment plate is provided at the lower part of the lifting mechanism 6, and the two lifting mechanisms 6 are connected in the elongated mounting groove 81 through the adjustment plate.
