Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater pool foam cleaning device. Background Technology

[0002] During wastewater treatment, a large amount of foam is generated during the mixing process. In order not to affect the subsequent purification and treatment operations, this foam needs to be removed.

[0003] The traditional method involves manually moving the foam to the edge of the sewage tank, then using a shovel or net to scoop it out and dump it. This manual method of moving and scooping is not only inefficient but also labor-intensive, and it cannot even guarantee that the foam is completely moved and removed. Furthermore, when the liquid level in the tank is low, it may be impossible to move the foam manually, and there are also certain safety risks associated with manual operation.

[0004] To address this, we designed a foam cleaning device for sewage tanks. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a foam cleaning device for sewage tanks.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A foam cleaning device for sewage tanks includes a crossbeam, a drive assembly, and a filter structure. The outer end of the crossbeam has a downwardly extending extension. One side of the filter structure is hinged to the lower end of the extension, and the other side is connected to the outer end of the crossbeam with a tension member to facilitate the filter structure to be in a foam-collecting posture. The inner end of the crossbeam is provided with a drive assembly that can drive the filter structure to rise and fall and move in a horizontal plane.

[0008] Preferably, the filter structure includes a planar frame on which the filter is laid.

[0009] Preferably, a tail frame is provided on one side of the lower end of the planar frame corresponding to the extension, and the tail frame is also covered with a filter screen.

[0010] Preferably, the planar frame has end frames at both ends, and the end frames are connected to the tail frame, and the end frames are also covered with filter screens.

[0011] Preferably, the connection point between the extension and the filter structure is located below the tail frame.

[0012] Preferably, the upper end of the tension member is connected to the outer end of the crossbeam, and the lower end of the tension member is connected to the side of the filter structure opposite to the lower end of the extension.

[0013] Preferably, the pulling member is a rope or a rod of fixed length, and the lower end of the pulling member is detachably connected to the filter screen structure.

[0014] Preferably, the pulling member is a telescopic rod, and the lower end of the pulling member is hinged to the corresponding filter screen structure.

[0015] Preferably, the drive assembly includes a vertical positioner and a horizontal rotary positioner, the fixed part of the vertical positioner is correspondingly installed on the rotating part of the horizontal rotary positioner, and the inner end of the crossbeam is correspondingly connected to the lifting part of the vertical positioner.

[0016] Preferably, the drive assembly further includes a fixed base for mounting the horizontal rotary positioner.

[0017] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0018] 1. The filter screen structure can be put into a foam-catching posture by the drive component. Under the action of the rotation direction of the sewage in the sewage tank, the sewage passes through the filter screen structure. At this time, the filter screen structure can effectively catch the foam. It can also move the filter screen structure to the outside of the sewage tank and remove the foam on the filter screen structure, thus solving the technical problem of manually pushing the foam to the edge and then using a shovel to scoop out and dump the foam.

[0019] 2. The tail frame and end frame not only prevent foam from overflowing from the tail side and both ends of the planar frame when retrieval foam, but also allow the retrieval surface of the filter screen to tilt downwards when cleaning foam from the filter screen structure, thus facilitating the cleaning of foam from the filter screen structure.

[0024] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if terms such as "upper", "lower", "front", "rear", "left", "right" indicate orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention. It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. They are used for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation.

[0025] Example 1, in conjunction with Appendix Figure 1-3 A foam cleaning device for sewage tanks includes a crossbeam 1, a drive assembly 2, and a filter structure 3. The outer end of the crossbeam 1 is provided with a downwardly extending extension 11. One side of the filter structure 3 is hinged to the lower end of the extension 11, and the other side is provided with a tension member 4 between it and the outer end of the crossbeam 1, so that the filter structure 3 can be in a foam-collecting posture. Specifically, the foam-collecting posture of the filter structure 3 is that the filter structure 3 is in an inclined state. When in use, one side of the filter structure 3 is higher than the liquid level in the tank, and the other side is lower than the liquid level in the tank. The inner end of the crossbeam 1 is provided with a drive assembly 2 that can drive the filter structure 3 to rise and fall and move its position in the horizontal plane.

[0026] As needed, the drive assembly 2 includes a vertical positioner 21 and a horizontal rotary positioner 22. The vertical positioner 21 drives the crossbeam 1 to rise and fall, thereby driving the filter structure 3 to rise and fall. The horizontal rotary positioner 22 drives the crossbeam 1 to rotate, thereby moving the filter structure 3 in the horizontal plane. That is, in use, the horizontal rotary positioner 22 first moves the filter structure 3 above the sewage tank, and then the vertical positioner 21 drives the crossbeam 1 to fall, so that one side of the filter structure 3 is higher than the liquid surface in the tank, and the other side is lower than the liquid surface in the tank. At this time, under the action of the rotation direction of the sewage in the sewage tank, the sewage passes through the filter structure 3. At this time, the filter structure 3 can effectively catch the foam. Based on the above principle, the filter structure 3 can be moved outside the sewage tank and the foam on the filter structure 3 can be removed. This solves the technical problem of manually pushing the foam to the edge and then using a bucket to scoop it out and dump it. After the retrieval is completed, the above actions can be reversed to move the filter structure 3 to the outside of the sewage tank.

[0027] As needed, the vertical positioner 21 can be a combination of a vertically arranged slide rail pair and a lead screw motor, with the sliding part of the slide rail pair threadedly engaged with the lead screw part of the lead screw motor; the vertical positioner 21 can also be a vertically arranged hydraulic rod.

[0028] Preferably, the fixed part of the vertical positioner 21 is installed on the rotating part of the horizontal rotary positioner 22, and the inner end of the crossbeam 1 is connected to the lifting part of the vertical positioner 21.

[0029] Furthermore, the drive assembly 2 also includes a fixed base 23 for mounting the horizontal rotary positioner 22.

[0030] As needed, the filter structure 3 includes a planar frame 31, on which a filter 32 is laid.

[0031] In this embodiment, one side of the planar frame 31 is hinged to the lower end of the extension 11, and the other side is connected to the tension member 4.

[0032] As needed, when the pulling member 4 is a rope, the upper end of the pulling member 4 is fixedly connected to the outer end of the crossbeam 1, and the lower end is detachably connected to the side of the filter structure 3; when the pulling member 4 is a rod of fixed length, the upper end of the pulling member 4 is hinged to the outer end of the crossbeam 1, and the lower end is detachably connected to the side of the filter structure 3; when the pulling member 4 is a telescopic rod, the upper end of the pulling member 4 is hinged to the outer end of the crossbeam 1, and the lower end is hinged to the side of the filter structure 3.

[0033] Example 2, in conjunction with Appendix Figure 1-3 A wastewater tank foam cleaning device, based on Embodiment 1, has a tail frame 33 on one side of the lower end of the extension 11 corresponding to the planar frame 31, and the tail frame 33 is also covered with a filter screen 32; this can prevent the salvaged foam from overflowing from the tail side of the planar frame 31.

[0034] As needed, the connection between the extension 11 and the filter structure 3 is located below the tail frame 33. That is, when removing foam from the filter 32, the pulling member 4 is disconnected from the filter structure 3. At this time, the filter structure 3 rotates under the action of gravity. After the filter structure 3 is in a balanced posture, the opening of the overall structure formed by the planar frame 31 and the tail frame 33 faces downward, that is, the retrieval surface of the filter 32 is tilted downward, thus removing foam from the filter 32 in this direction.

[0035] Depending on the requirements, the angle between the tail frame 33 and the planar frame 31 is a right angle or an obtuse angle; preferably, the angle between the tail frame 33 and the planar frame 31 is 90 to 145 degrees.

[0036] Example 3, in conjunction with Appendix Figure 1-3 A wastewater tank foam cleaning device, based on Embodiment 2, has end frames 34 at both ends of the planar frame 31, and the end frames 34 are correspondingly connected to the tail frame 33. The end frames 34 are also covered with filter screens 32, which can prevent the salvaged foam from overflowing from both ends of the planar frame 31.

[0037] Depending on the requirements, the angle between the end frame 34 and the planar frame 31 is a right angle or an obtuse angle; preferably, the angle between the end frame 34 and the planar frame 31 is 90 to 145 degrees.

[0038] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
