[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Reference Figures 1 to 4A pharmaceutical wastewater treatment device includes a wastewater treatment tank 1 and an auxiliary tank 2 fixedly connected to the outer wall of the wastewater treatment tank 1. The top of the wastewater treatment tank 1 is provided with a feed inlet 3. The wastewater treatment tank 1 is used to collect and pre-treat pharmaceutical wastewater, while the auxiliary tank 2 is located on the right side of the wastewater treatment tank 1 and is wider than the wastewater treatment tank 1 to ensure that the filter plate 46 can rotate inside the auxiliary tank 2. A partition is provided between the wastewater treatment tank 1 and the auxiliary tank 2 to allow the filter assembly 4 to pass through, thereby reducing the amount of wastewater entering the auxiliary tank 2.

[0024] Furthermore, the filter assembly 4 installed inside the wastewater treatment tank 1 includes a lead screw 42, a filter plate 46 installed on the top of the lead screw 42, and a guide ring 43 meshing with the outside of the lead screw 42. The surface of the filter plate 46 is provided with micropores for wastewater to pass through, leaving behind drug residues and solid impurities. However, the filter plate 46 cannot have an adsorption effect, thus ensuring that the filter plate 46 can pour out solid impurities during the flipping process. The outer walls of the guide ring 43 are designed with protrusions at both ends, which can limit the outer block 44 and keep the outer block 44 always outside the guide ring 43.

[0025] In addition, the idling component 5 includes a slot 57 formed on the end face of the guide ring 43 and a locking plate 53 that engages with the slot 57; wherein, the engagement between the locking plate 53 and the slot 57 enables the connection between the guide ring 43 and the outer block 44, allowing the guide ring 43 to switch between two states: horizontal movement in a stationary state or synchronous rotation with the lead screw 42.

[0026] And, the collection component 6 includes a collection plate 62 disposed on the bottom wall of the auxiliary tank 2. The size of the collection plate 62 needs to be larger than the size of the filter plate 46 and be adapted to the inner wall of the auxiliary tank 2 to prevent impurities from falling to the outside of the collection plate 62 during the flipping process of the filter plate 46.

[0027] Specifically, the filter assembly 4 also includes a motor 41 fixedly installed on the inner wall of the wastewater treatment tank 1. The output end of the motor 41 is fixedly connected to one end of the lead screw 42, and the other end of the lead screw 42 is rotatably connected to the inner wall of the auxiliary tank 2. The motor 41 provides power input to the filter assembly 4, and through automated control, the lead screw 42 can be rotated as needed.

[0028] Furthermore, an outer block 44 is provided on the outer wall of the guide ring 43, and a connecting ring 45 is fixedly connected to the outer wall of the guide ring 43. The connecting ring 45 is fixedly connected to the bottom wall of the filter plate 46. The outer block 44 is located on the outer wall of the guide ring 43, and the connection between the connecting ring 45 and the guide ring 43 allows the connecting ring 45 to rotate synchronously with the guide ring 43. The connecting ring 45 is positioned to the left of the outer block 44, thereby preventing the filter plate 46 from interfering with the guide plate 51 during the flipping process.

[0029] Reference Figure 2 , Figure 3 and Figure 4 The inner wall of the outer block 44 is slidably connected to a guide plate 51, and the outer wall of the clamping plate 53 is fixedly connected to a connecting rod 54. The outer wall of the guide plate 51 has an inclined groove 52 for the connecting rod 54 to slide, and the bottom of the inclined groove 52 is closer to the motor 41. The inclined groove 52 is designed to be lower on the left and higher on the right, so that as the guide plate 51 moves to the left, the contact position of the connecting rod 54 with the inclined groove 52 gradually increases, thereby achieving the effect of the clamping plate 53 moving upward.

[0030] Specifically, a fixing block 55 is fixedly connected to the outer wall of the outer block 44, and a locking plate 53 is slidably connected inside the outer block 44. The locking plate 53 and the fixing block 55 are connected by a spring 56. The locking plate 53 and the fixing block 55 can be connected by a telescopic rod, so that when the locking plate 53 rises, it compresses the spring 56, providing power for the next reset of the locking plate 53.

[0031] Reference Figure 2 The auxiliary tank 2 has slide rails 61 fixedly installed on both sides of its inner bottom wall. The collection plate 62 is slidably connected to the surface of the slide rails 61, and a sealing plate 63 is installed on the outer wall of the auxiliary tank 2. The collection plate 62 slides on the inner wall of the auxiliary tank 2 via the slide rails 61. Together with the sealing plate 63, it facilitates the quick removal and processing of collected dregs and impurities. The surface of the sealing plate 63 can be designed with micropores that allow only wastewater to pass through, thereby allowing wastewater entering the auxiliary tank 2 to be discharged.

[0032] Working principle: Pharmaceutical wastewater to be treated is poured into wastewater treatment tank 1 through inlet 3. Before treating the wastewater, motor 41 controls screw 42 to rotate, controlling filter plate 46 to move closer to motor 41. At this time, clamping plate 53 is clamped into groove 57 on outer wall of guide ring 43 by gravity and spring force 56, so that guide ring 43 and outer block 44 are connected. Due to the meshing action between screw 42 and guide ring 43, guide ring 43 and outer block 44 move to center position of screw 42 in a stationary state, so that filter plate 46 is attached to inner wall of wastewater treatment tank 1 through connecting ring 45. During the process of wastewater pouring, the filter plate 46 can filter the drug residue or other impurities in the wastewater.

[0033] After feeding is completed, the motor 41 is started to reverse, causing the outer block 44 to move closer to the auxiliary tank 2. When the outer block 44 moves to the end of the screw 42, the guide plate 51 contacts the inner wall of the auxiliary tank 2 and moves to the left. Since the outer wall and the inside of the outer block 44 are provided with multiple sliding grooves for the movement of parts, during the movement of the guide plate 51, the inner wall of the inclined groove 52 will cause the connecting rod 54 to move upward gradually, thereby driving the clamping plate 53 to rise synchronously and disengage from the clamping groove 57. At this time, the guide ring 43 is released from its restriction and rotates synchronously with the screw 42, thereby driving the filter plate 46 to rotate synchronously and pouring the filtered impurities into the collection plate 62. After the pouring is completed, the motor 41 rotates forward, driving the guide ring 43 and the outer block 44 to move to the left. The guide plate 51 moves away from the auxiliary tank 2, and the clamping plate 53 is reset by the elastic force of the spring 56 and continues to be clamped into the clamping groove 57.

[0034] The collection plate 62 can slide on the inner wall of the auxiliary tank 2 via the slide rail 61. At the same time, the outer wall of the auxiliary tank 2 is provided with a sealing plate 63 that is slightly larger than the collection plate 62, which makes it easy for personnel to take out or put in the collection plate 62, thus improving the convenience of using the device.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
