[0002] Wastewater generated during the production of plastic bottles contains large amounts of organic matter, ammonia nitrogen, and other pollutants. Direct discharge into the environment would cause serious pollution to surrounding water bodies. To address this issue, a combined biological filter system can be used for the ecological purification of wastewater from plastic bottle production. For example, utility model patent CN209989133U discloses a combined aerated biological filter, including a main tank. An inlet pipe is provided on one side of the main tank, and a biological filter media tank is provided above the inlet pipe. The outlet of the biological filter media tank is fixedly connected to the inlet of the main tank through a filter media conveying pipe. An air inlet pipe is provided on the other side of the main tank, and an aeration pipe is provided above the air inlet pipe. One end of the aeration pipe passes through and extends into the interior of the main tank. An anaerobic zone is provided inside the main tank, and an aerobic zone is provided above the anaerobic zone. A partition is provided between the anaerobic zone and the aerobic zone. Filter heads are installed inside the partition, and there are six filter heads. Fixing plates are provided on both sides of each filter head, and the fixing plates are threadedly connected to the partition by screws. However, the aforementioned patent has the following shortcomings: When the device is in use, it lacks an anti-clogging mechanism, making the fine and coarse filters prone to clogging, which reduces their efficiency. Furthermore, the lack of a winding mechanism makes it difficult to wind up the wiring terminals, hindering the device's usability. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a combined biological filter device for the ecological purification of wastewater from plastic bottle production. It solves the problems that when the device is in use, the fine and coarse filter screens are prone to clogging due to the lack of an anti-clogging mechanism, which reduces the working efficiency of the fine and coarse filter screens. In addition, the lack of a winding mechanism makes it inconvenient to wind up the wiring terminals, making the device inconvenient to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a combined biological filter device for ecological purification of wastewater from plastic bottle production, comprising a biological filter body, a partition fixedly connected inside the biological filter body, a shell in contact with the inside of the partition, a fixing plate fixedly connected to the outside of the shell, the fixing plate in contact with the partition, a screw threadedly connected inside the partition, the screw in contact with the fixing plate, a fine filter screen fixedly connected inside the shell, a coarse filter screen fixedly connected inside the shell, an anti-clogging mechanism provided on the biological filter body, a wiring terminal provided on the biological filter body, and a winding mechanism provided on the biological filter body.

[0005] Preferably, the anti-clogging mechanism includes a motor. The motor is fixedly connected to the lower end of the main body of the biological filter. The rotating shaft of the motor is rotatably connected to the main body of the biological filter. A rotating block is fixedly connected to the upper end of the rotating shaft of the motor. An impact rod is fixedly connected to the upper end of the rotating block. A fixing rod is fixedly connected to the outer side of the shell. An elastic block is fixedly connected to the lower end of the fixing rod. The outer side of the elastic block contacts the impact rod. By starting the motor, the motor drives the impact rod to impact the elastic block and vibrate. The vibration of the elastic block causes the fine and coarse filter screens to vibrate, thereby preventing clogging of the fine and coarse filter screens and preventing a reduction in the working efficiency of the fine and coarse filter screens in the device.

[0006] Preferably, the main body of the biological filter is fitted with a sealing sleeve, which is rotatably connected to the rotating block. By designing the sealing sleeve, water leakage can be prevented.

[0007] Preferably, the winding mechanism includes a connecting rod, which is fixedly connected to the main body of the biological filter. A fixing plate is fixedly connected to the upper end of the connecting rod. A screw is threadedly connected to the inside of the fixing plate. A handle is fixedly connected to the upper end of the screw. A connecting sleeve is rotatably connected to the outside of the screw. A limiting plate is fixedly connected to the lower end of the connecting sleeve. A guide rod is slidably connected to the inside of the fixing plate. The guide rod is fixedly connected to the limiting plate, and the limiting plate is slidably connected to the connecting rod. By winding the terminal block around the connecting rod to a designated position, and then rotating the screw and fixing plate, a threaded movement occurs. The rotation of the screw causes the limiting plate and other components to move. The limiting plate then contacts the terminal block, thereby limiting the terminal block and winding it up, making the device easy to use.

[0008] Preferably, a bearing is fixedly fitted inside the connecting sleeve, and a screw is fixedly fitted inside the inner ring of the bearing. By designing the bearing, the screw can be supported to rotate.

[0009] Preferably, the fixed plate is provided with ball bearings inside, which contact the guide rod. By designing the ball bearings, the friction between the fixed plate and the guide rod can be reduced.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model designs components such as a motor, rotating block, sealing sleeve, impact rod, fixing rod, and elastic block. When the motor is started, it drives the impact rod to impact the elastic block and vibrate. The vibration of the elastic block causes the fine and coarse filter screens to vibrate, thereby preventing the fine and coarse filter screens from becoming clogged and preventing the working efficiency of the fine and coarse filter screens on the device from decreasing.

[0012] 2. This utility model designs components such as a connecting rod, a fixing plate, a screw, a handle, a connecting sleeve, and a bearing. The terminal is wound onto a designated position on the connecting rod, and then the screw is rotated to create a threaded motion with the fixing plate.

[0021] Please see Figure 3 , Figure 4 The anti-clogging mechanism 8 includes a motor 81. The motor 81 is fixedly connected to the lower end of the biological filter body 1. The rotating shaft of the motor 81 is rotatably connected to the biological filter body 1. A rotating block 82 is fixedly connected to the upper end of the rotating shaft of the motor 81. A sealing sleeve 83 is fixedly fitted inside the biological filter body 1. The sealing sleeve 83 is rotatably connected to the rotating block 82. By designing the sealing sleeve 83, water leakage can be prevented. An impact rod 84 is fixedly connected to the upper end of the rotating block 82. A fixing rod 85 is fixedly connected to the outer side of the shell 3. An elastic block 86 is fixedly connected to the lower end of the fixing rod 85. The outer side of the elastic block 86 contacts the impact rod 84. By starting the motor 81, the motor 81 drives the impact rod 84 to impact the elastic block 86 and vibrate. The vibration of the elastic block 86 drives the fine filter screen 6 and the coarse filter screen 7 to vibrate, thereby preventing the fine filter screen 6 and the coarse filter screen 7 from clogging and preventing the working efficiency of the fine filter screen 6 and the coarse filter screen 7 on the device from decreasing.

[0022] Please see Figure 1 , Figure 3 , Figure 5The winding mechanism 10 includes a connecting rod 101. The connecting rod 101 is fixedly connected to the main body 1 of the biological filter. A fixing plate 102 is fixedly connected to the upper end of the connecting rod 101. A screw 103 is threadedly connected to the inside of the fixing plate 102. A handle 104 is fixedly connected to the upper end of the screw 103. A connecting sleeve 105 is rotatably connected to the outside of the screw 103. A bearing 106 is fixedly sleeved inside the connecting sleeve 105. The screw 103 is fixedly sleeved inside the inner ring of the bearing 106. By designing the bearing 106, the screw 103 can be supported to rotate. A limit plate 107 is fixedly connected to the lower end of the connecting sleeve 105. A guide rod 10 is slidably connected inside the fixing plate 102. 8. The guide rod 108 is fixedly connected to the limiting plate 107. The fixed plate 102 is provided with a ball bearing 109 inside. The ball bearing 109 contacts the guide rod 108. By designing the ball bearing 109, the friction between the fixed plate 102 and the guide rod 108 can be reduced. The limiting plate 107 is slidably connected to the connecting rod 101. By winding the terminal 9 onto the connecting rod 101 at a designated position, and then rotating the screw 103 to cause threaded movement with the fixed plate 102, the screw 103 rotates and drives the limiting plate 107 and other components to move. The limiting plate 107 moves and contacts the terminal 9, thereby limiting the terminal 9 and allowing the terminal 9 to be wound up, making the device easy to use.

[0023] The specific implementation process of this utility model is as follows: When the device is in use, the motor 81 is started, the motor 81 drives the rotating block 82 to rotate, the rotating block 82 drives the impact rod 84 to rotate, the impact rod 84 rotates and impacts the elastic block 86, thereby causing the elastic block 86 to vibrate, the vibration of the elastic block 86 drives the fixed rod 85 to vibrate, the vibration of the fixed rod 85 drives the housing 3 to vibrate, the vibration of the housing 3 drives the fine filter screen 6 and the coarse filter screen 7 to vibrate, thereby preventing the fine filter screen 6 and the coarse filter screen 7 from becoming clogged, and preventing the working efficiency of the fine filter screen 6 and the coarse filter screen 7 on the device from decreasing;

[0024] When the terminal 9 on the device needs to be wound up, the terminal 9 is wound around the designated position on the connecting rod 101, and then the handle 104 is turned. The rotation of the handle 104 drives the screw 103 to rotate. The rotation of the screw 103 causes threaded movement with the fixing plate 102, which in turn causes the screw 103 to have relative displacement. The rotation of the screw 103 causes the bearing 106 and the connecting sleeve 105 to move downward. The downward movement of the connecting sleeve 105 causes the limiting plate 107 to move downward. The downward movement of the limiting plate 107 causes the guide rod 108 to move downward. The downward movement of the limiting plate 107 contacts the terminal 9, thereby limiting the terminal 9 and winding it up, making the device easy to use.
