Description

Technical Field

[0001] This utility model relates to the field of biological packing bed technology, and in particular to a biological packing bed. Background Technology

[0002] Chinese patent document CN217103260U discloses a portal-type biological packing bed for river purification, comprising multiple packing bed supports spaced apart along the water flow direction of the river. Each packing bed support includes two control shafts, two frames, two ground-pin traction mechanisms, two controllers, two wireless transceivers, two flow meters, and two solar panels. The two control shafts are fixed on both sides of the river. The two frames are hinged to the electronic shafts on the corresponding control shafts, and a ground-pin is installed at the lower end of the riverside uprights of each of the two frames. The two ground-pin traction mechanisms are each installed on the two frames. The two controllers are each installed in the inner cavity of the two control shafts and connected to the traction motor and the electronic shaft. The two wireless transceivers are installed in the inner cavity of the two control shafts. The two flow meters are installed at the lower end of the two frames and connected to the controllers and the wireless transceivers. The two solar panels are fixed to the top of the two control shafts. This invention enables automated control.

[0003] However, the aforementioned biological packing beds, including some existing ones, generally rigidly connect the biological packing membrane to the frame, and the frame is fixed to the main structure. When the packing membrane suffers structural damage, blockage, or functional failure due to hydraulic shear, excessive biofilm proliferation, or foreign object entanglement, it cannot be replaced independently. This necessitates shutdown and disassembly of the entire frame, which not only significantly increases maintenance time and economic costs but also prolongs the downtime of the wastewater treatment system, directly affecting the stability of water quality compliance and discharge. Therefore, we propose a biological packing bed. Utility Model Content

[0004] The purpose of this invention is to provide a biological packing bed that can solve the problem that some existing biological packing beds cannot have their biological packing membranes replaced individually.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a biological packing bed, comprising: The first mounting column has a second mounting column on one side. A movable frame is hinged to the side of the first mounting column that is close to the second mounting column, and a biological packing membrane is inserted into the movable frame. A connecting mechanism, which is located at the top of the second mounting post, is used to assist in the switching of the movable frame; The snap-fit ​​mechanism is located on the movable frame and includes a plug rod and a pull handle. The plug rod is movably inserted through both the movable frame and the biological packing membrane, and a pull handle is fixedly installed at one end of the plug rod.

[0006] Preferably, the locking mechanism further includes a spring, with the spring sleeved on the insertion rod, one end of the spring being fixedly connected to the front outer surface of the movable frame, and the other end of the spring being fixedly connected to the pull handle.

[0007] Preferably, the connecting mechanism includes a housing, a servo motor, a connecting rope, and a connecting rod. The housing is fixedly installed on the top of the second mounting column, the servo motor is fixedly installed on the top of the housing, a winding roller is rotatably installed between the inner top and inner bottom of the housing, the shaft of the servo motor is connected to the winding roller for transmission, the connecting rope is fixedly connected to the winding roller, and the connecting rod is fixedly installed on the top of the movable frame. One end of the connecting rope is fixedly connected to the connecting rod.

[0008] Preferably, a flow meter is fixedly installed on one outer surface of the first mounting column.

[0009] Preferably, a groove is provided on the side of the second mounting post that is close to the movable frame, and an electromagnet is fixedly installed in the groove, with the electromagnet fitting against the movable frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) This biological packing bed, through the cooperation of the movable frame, biological packing membrane and snap-fit ​​mechanism, can quickly remove and replace the biological packing membrane from the movable frame when it is damaged. This solves the problem that some existing biological packing beds generally have the biological packing membrane rigidly connected to the frame and the frame fixed to the main structure. When the packing membrane is structurally damaged, blocked or functionally failed due to hydraulic shear, excessive biofilm proliferation or foreign object entanglement, it cannot be replaced independently, which requires shutdown and disassembly of the entire frame. This not only greatly increases maintenance time and economic costs, but also prolongs the shutdown cycle of the sewage treatment system, directly affecting the stability of water quality compliance discharge. This improves the practicality of the biological packing bed.

[0013] (2) The biological packing bed, through the cooperation of flow meter and electromagnet, can control the switch of electromagnet by monitoring water flow velocity, and open the movable frame in time with the connection mechanism to protect the biological packing membrane, thus ensuring the effectiveness of the biological packing bed and facilitating its promotion and use.

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a biological packing bed, including a first mounting column 1, a connecting mechanism 6 and a snap-fit ​​mechanism 5. A second mounting column 2 is provided on one side of the first mounting column 1. A movable frame 3 is hingedly installed on the side of the first mounting column 1 close to the second mounting column 2. A biological packing membrane 4 is inserted into the movable frame 3. The connecting mechanism 6 is located on the top of the second mounting column 2 and is used to assist the opening and closing of the movable frame 3. A flow meter 7 is fixedly installed on the outer surface of one side of the first mounting column 1. A groove is opened on the side of the second mounting column 2 close to the movable frame 3. An electromagnet 8 is fixedly installed in the groove and fits against the movable frame 3. A handle groove 9 is opened on the top of the movable frame 3. A solar panel 10 is fixedly installed on the top of the first mounting column 1. The snap-fit ​​mechanism 5 is set on the movable frame 3. The snap-fit ​​mechanism 5 includes a plug rod 51 and a pull handle 52. The plug rod 51 is movably passed through both the movable frame 3 and the biological packing membrane 4. The pull handle 52 is fixedly installed at one end of the plug rod 51.

[0018] The snap-fit ​​mechanism 5 also includes a spring 53. The spring 53 is sleeved on the insertion rod 51. One end of the spring 53 is fixedly connected to the front outer surface of the movable frame 3, and the other end of the spring 53 is fixedly connected to the pull handle 52. Through the cooperation of the movable frame 3, the biological packing membrane 4 and the snap-fit ​​mechanism 5, the biological packing membrane 4 can be quickly removed from the movable frame 3 and replaced when it is damaged. This solves the problem that some existing biological packing beds generally have the biological packing membrane rigidly connected to the frame and the frame is fixed to the main structure. When the packing membrane is structurally damaged, blocked or functionally failed due to hydraulic shear, excessive biofilm proliferation or foreign object entanglement, it cannot be replaced independently. This leads to the need to shut down the machine and disassemble the entire frame, which not only greatly increases maintenance time and economic costs, but also prolongs the shutdown cycle of the sewage treatment system and directly affects the stability of water quality discharge. This improves the practicality of the biological packing bed.

[0019] The connecting mechanism 6 includes a housing 61, a servo motor 62, a connecting rope 63, and a connecting rod 64. The housing 61 is fixedly installed on the top of the second mounting column 2, and the servo motor 62 is fixedly installed on the top of the housing 61. A winding roller is rotatably installed between the top and bottom inner sides of the housing 61. The shaft of the servo motor 62 is connected to the winding roller for transmission. The connecting rope 63 is fixedly connected to the winding roller. The connecting rod 64 is fixedly installed on the top of the movable frame 3. One end of the connecting rope 63 is fixedly connected to the connecting rod 64. Through the cooperation of the flow meter 7 and the electromagnet 8, the electromagnet 8 can be switched on and off by monitoring the water flow rate. This, in conjunction with the connecting mechanism 6, opens the movable frame 3 in a timely manner, protecting the biological packing membrane 4 and ensuring the effectiveness of the biological packing bed. This is beneficial for the promotion and use of the biological packing bed.

[0020] Working principle: During use, the flow meter 7 monitors the flow velocity of the riverbed. When the flow velocity reaches a certain value, the electromagnet 8 is de-energized, releasing the magnetic force and releasing the attraction to the movable frame 3. At the same time, the servo motor 62 starts and drives the winding roller to rotate and release the connecting rope 63. The movable frame 3 rotates and opens under the action of the water flow, avoiding impact on the biological packing membrane 4. When the biological packing membrane 4 is damaged, pull the handle 52 to drive the insertion rod 51 to pull it outward until it is detached from the biological packing membrane 4. Then the biological packing membrane 4 can be removed from the movable frame 3 and replaced.

[0021] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
