Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a membrane replacement mechanism for an oil-water separation device used in wastewater treatment. Background Technology

[0002] In industrial production and other fields, oily wastewater usually contains various chemicals, heavy metals and other harmful components. In the process of treating this oily wastewater, the use of oil-water separation devices can separate the oil from the wastewater, thereby reducing the content of harmful substances and reducing the degree of pollution. At the same time, the separation membrane of the oil-water separation device needs to be replaced in time after a period of use.

[0003] In existing technologies, when replacing the separator membrane in an oil-water separator, the separator membrane assembly is typically pulled out by pulling a traction rope after removing the bolt fasteners. However, the repeated disassembly and reassembly of the bolt fasteners often makes the entire separator membrane replacement operation extremely cumbersome and inconvenient, and also causes operational difficulties during the replacement process. Therefore, a separator membrane replacement mechanism for an oil-water separator used in wastewater treatment is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a membrane replacement mechanism for an oil-water separation device for wastewater treatment, so as to solve the problem that the replacement operation of the membrane in the oil-water separation device in the prior art is cumbersome and inconvenient as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A membrane replacement mechanism for an oil-water separation device in wastewater treatment includes an oil-water separation frame. An inner insert frame is inserted into the inner side of the oil-water separation frame. Baffles are provided at the front and rear ends of the inner insert frame. A square rod is fixedly connected to the top of the baffle. Side slots are opened on both sides of the square rod near the middle position. Side clamping plates are provided on the inner side of the side slots. A set of side clamping plates are connected to each other by a traction rope body. An insert rod is fixedly connected to the side of the side clamping plate away from the traction rope body. An inner groove is opened on one side of the insert rod. A first upright plate is fixedly connected to the inner side of the inner groove. A spring is fixedly connected to one side of the first upright plate. A second upright plate is fixedly connected to the side of the spring away from the first upright plate.

[0007] Preferably, a bottom bracket is fixedly connected to the lower inner side of the oil-water separation frame, the lower part of the inner frame is inserted into the bottom bracket, and the separation membrane body is clamped in the middle of the inner frame.

[0008] Preferably, a docking strip is fixedly connected to the bottom of the square rod. The docking strip has a tapered strip structure, and a docking groove is provided at the top of the inner frame to engage with the docking strip.

[0009] Preferably, a retaining frame is fixedly connected to one side of each of the side plates, and the retaining frame is sleeved on the upper part of the traction rope body. The retaining frame has an inverted "U" shape.

[0010] Preferably, the square rod and a set of the insert rods are slidably connected, the square rod and the second upright plate are fixedly connected, the oil-water separation frame has a square slot inside that engages with the insert rod, and the insert rod and the side plate are vertically arranged.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the traction rope body, side locking plate, insert rod, inner groove, first upright plate, spring, and second upright plate facilitate the replacement mechanism of the separation membrane in the wastewater treatment oil-water separator. During periodic disassembly and replacement of the separation membrane body, the entire mechanism can be pulled outwards by the traction rope body, allowing the elastic insert rod structure (composed of the side locking plate, insert rod, inner groove, first upright plate, spring, and second upright plate) to remove its restrictive operation on the separation membrane body. This enables the subsequent disassembly and replacement operation to be completed conveniently without removing the bolt fasteners. Unlike previous methods that required removing bolt fasteners, the flexible use of this replacement mechanism reduces the cumbersomeness of actual disassembly and replacement of the separation membrane body, while also minimizing unnecessary troubles during convenient replacement.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution:

[0020] A membrane replacement mechanism for an oil-water separation device for wastewater treatment includes an oil-water separation frame 1, an inner frame 2 inserted into the inner side of the oil-water separation frame 1, baffles 3 at the front and rear ends of the inner frame 2, a square rod 4 fixedly connected to the top of the baffles 3, side slots 6 on both sides of the square rod 4 near the middle, side clamping plates 7 on the inner side of the side slots 6, a set of side clamping plates 7 connected by a traction rope body 5, a rod 8 fixedly connected to the side of the side clamping plate 7 away from the traction rope body 5, an inner groove 9 on one side of the rod 8, a first upright plate 10 fixedly connected to the inner side of the inner groove 9, a spring 11 fixedly connected to one side of the first upright plate 10, and a second upright plate 12 fixedly connected to the side of the spring 11 away from the first upright plate 10.

[0021] like Figure 1 As shown, a bottom bracket 14 is fixedly connected to the lower inner side of the oil-water separation frame 1. The lower part of the inner frame 2 is inserted into the bottom bracket 14. The separation membrane body 13 is clamped in the middle of the inner frame 2. When the inner frame 2 is replaced and the new separation membrane body 13 is clamped back into the oil-water separation frame 1, the bottom bracket 14 mainly serves to assist in limiting the inner frame 2.

[0022] like Figure 1 and Figure 2 As shown, a docking strip 15 is fixedly connected to the bottom of the square rod 4. The docking strip 15 has a tapered strip structure. A docking slot 16 is provided at the top of the inner frame 2 to engage with the docking strip 15. After the docking strip 15 and the docking slot 16 are engaged, the square rod 4 can be combined with the inner frame 2. This engaging docking design also facilitates the reciprocating use of the square rod 4 to complete the corresponding disassembly and replacement operations.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a set of side plates 7 are fixedly connected to a baffle 17 on opposite sides. The baffle 17 is fitted above the traction rope body 5. The baffle 17 has an inverted "U" shape. When the traction rope body 5 is pulled outward to replace the separation membrane body 13, the baffle 17 mainly serves to limit the two ends of the traction rope body 5. The square rod 4 and a set of insert rods 8 are slidably connected. The square rod 4 and the second upright plate 12 are fixedly connected. The inside of the oil-water separation frame 1 has a square slot that engages with the insert rod 8. The insert rod 8 and the side plates 7 are vertically arranged. When the set of insert rods 8 moves in the same direction, the second upright plate 12 mainly serves to assist in limiting the spring 11.

[0024] Workflow: As oily wastewater is gradually fed into the oil-water separator from front to back through the discharge pipeline, the oil-water separation frame 1 and the inner insert frame 2 work together to separate and filter the oily wastewater through the separation membrane body 13. When the separation membrane body 13 needs to be removed and replaced after a period of use, the hook first hooks the traction rope body 5 and pulls the traction rope body 5 upward. At the same time, under the constraint of the baffle frame 17 and the side slot 6, a set of side clamping plates 7 will be pulled and move the left and right sets of inserting rods 8 in the same direction towards the middle of the square rod 4, so that the set of inserting rods 8 are separated from the oil-water separation frame 1. Then, simply continue to pull the traction rope body 5 upward to quickly pull out and remove the inner insert frame 2 and the separation membrane body 13 clamped in the middle position, so that the operator can replace the new separation membrane according to the original clamping method.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
