Description

Technical Field

[0001] This application relates to the field of pharmaceutical residue treatment technology, and more specifically, to a liquid unloading device and pharmaceutical residue treatment equipment. Background Technology

[0002] The screw extrusion trolley is a specialized piece of equipment used in the pharmaceutical industry for the automatic conveying of waste residue from traditional Chinese medicine (TCM) products, separating the liquid from the residue. When the extraction tank requests a discharge, the screw extrusion trolley is started and moves to a position below the extraction tank. It then stops at a designated location, and the TCM waste residue is discharged from the extraction tank's discharge gate into the screw extrusion trolley. After loading, the screw extrusion trolley moves to the unloading position, and the discharge device is activated to extrude the material, achieving the separation of the liquid and residue from the TCM residue.

[0003] In related technologies, the dredged pharmaceutical residue from the screw extruder is discharged into a storage bin, while the waste liquid is discharged or recycled through pipelines. However, the flow rate is often too high when discharging waste liquid, which can easily prevent it from being discharged into the sewage pipe in time, causing large-scale pollution in the dredging area. Furthermore, pharmaceutical residue is often discharged during unloading, which can easily cause pipeline blockage. Utility Model Content

[0004] In order to at least address some of the deficiencies mentioned in the related technologies, this application provides a liquid unloading device and a pharmaceutical residue treatment equipment.

[0005] To achieve the above objectives, this application provides a liquid unloading device for a screw extrusion vehicle. The liquid unloading device includes a housing and a filter assembly. A liquid collection chamber is provided on the housing, and the liquid collection chamber has an opening communicating with the outside environment facing the screw extrusion vehicle; a liquid outlet communicating with a sewage pipe is provided at the bottom of the liquid collection chamber, and the bottom of the liquid collection chamber is inclined towards the liquid outlet. The filter assembly includes a filter plate, which is detachably installed at the liquid outlet.

[0006] Furthermore, the housing is configured as a rectangular frame, and the opening is also configured as a rectangle, with the edge of the opening located near the edge of the housing.

[0007] Furthermore, the liquid outlet is located near a corner of the rectangular frame, and the bottom of the liquid collection chamber is inclined from the edge of the rectangular frame toward the liquid outlet.

[0008] Furthermore, the bottom of the liquid collection chamber is provided with a liquid outlet, which is horizontally positioned and has its outlet located at the center. The filter plate is detachably installed on the liquid outlet and can cover the outlet.

[0009] Furthermore, the filter plate includes a filtering section and a fixing section, with the filtering section disposed at the center of the filter plate. When the filter plate is installed on the liquid outlet section, the filtering section abuts against the liquid outlet, and the area of ​​the filtering section is S1, and the area of ​​the liquid outlet is S2, satisfying: S1 > S2.

[0010] Furthermore, the liquid outlet is configured as a rectangular plate, with limit posts at at least two opposite corners of the rectangular plate. The fixing part is correspondingly provided with limit holes, and the limit posts are inserted into the limit holes with an interference fit.

[0011] Furthermore, a support portion is provided on the side of the housing away from the liquid collection tank. The support portion is horizontally positioned so that the housing can be stably placed in the installation position.

[0012] This application also provides a pharmaceutical residue treatment device, including a screw extrusion trolley, rails, and the unloading device described in any of the above embodiments. The screw extrusion trolley is mounted on the rails and is capable of moving along the rails; the unloading device is disposed between the two rails.

[0013] Furthermore, one end of the screw extrusion vehicle is provided with a liquid outlet. The projected area of ​​the liquid outlet in the vertical direction is S3, and the projected area of ​​the opening on the liquid collection tank in the vertical direction is S4, satisfying: S3 < S4.

[0014] Furthermore, the direction of movement of the screw extrusion car along the track is the first direction. The length of the screw extrusion car in the first direction is L1, and the length of the opening on the liquid collection tank in the first direction is L2, satisfying: L1 < L2.

[0015] With the above technical solution, when using the unloading device of this application to unload liquid from a screw extrusion truck, the screw extrusion truck moves so that the position of the discharged waste liquid corresponds to the opening on the collection tank, after which the screw extrusion truck can unload liquid normally. The waste liquid falling into the collection tank will flow along the inclined bottom of the collection tank to the outlet and enter the sewage pipe from the outlet. If the unloading speed of the screw extrusion truck is too fast, the outlet cannot discharge in time, and the excess waste liquid will be temporarily stored in the collection tank and continue to flow from the outlet into the sewage pipe.

[0016] The unloading device of this application ensures that even if the discharge speed of the screw extruder exceeds the discharge speed at the outlet, the waste liquid will not flow arbitrarily and cause large-scale pollution. The waste liquid will be temporarily stored in the collection tank and continuously discharged into the sewage pipe. When the waste liquid passes through the outlet, it will also be filtered by the filter plate at the outlet, blocking the residue outside the sewage pipe and preventing pipe blockage.

[0017] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] This embodiment provides a liquid unloading device to solve the problems in related technologies, such as the excessively fast discharge speed of waste liquid from screw extrusion vehicles leading to large-scale pollution of the slag discharge area, and the easy blockage of sewage pipes by the pharmaceutical residue carried in the waste liquid.

[0027] Please see Figure 1 , Figure 2 This embodiment provides a liquid unloading device for a screw extrusion vehicle 300. The liquid unloading device includes a housing 100 and a filter assembly 200. A liquid collection chamber 110 is provided on the housing 100, and the liquid collection chamber 110 has an opening communicating with the outside in the direction facing the screw extrusion vehicle 300; a liquid outlet communicating with a sewage discharge pipe is provided at the bottom of the liquid collection chamber 110, and the bottom of the liquid collection chamber 110 is inclined towards the liquid outlet. The filter assembly 200 includes a filter plate 210, which is detachably installed at the liquid outlet.

[0028] Specifically, when using the unloading device of this embodiment to unload liquid from the screw extrusion cart 300, the screw extrusion cart 300 is moved so that the position of the waste liquid discharge on the screw extrusion cart 300 corresponds to the opening position of the collection tank 110. The screw extrusion cart 300 begins to discharge waste liquid, which falls from the opening into the collection tank 110 and flows along the inclined bottom of the collection tank 110 to the outlet, from where it falls into the sewage pipe.

[0029] When the discharge rate of the waste liquid from the screw extruder 300 exceeds the discharge rate of the outlet, the excess waste liquid will be temporarily stored in the collection bin 110 and continuously discharged from the outlet into the sewage pipe. It will not flow arbitrarily in the slag discharge area, thus preventing large-scale pollution. A filter plate 210 is also installed at the outlet. Any residue carried in the waste liquid will be filtered out by the filter plate 210 and remain on it, preventing it from flowing into the sewage pipe and causing blockage.

[0030] The unloading device in this embodiment allows the screw extruder 300 to discharge waste liquid at any discharge speed without causing large-scale pollution to the slag discharge area. The pharmaceutical residue carried in the waste liquid will not flow into the sewage pipe with the waste liquid, thus preventing blockage of the sewage pipe.

[0031] It should be noted that the residue is unlikely to completely clog the filter plate 210. Even if some of the residue partially clogs the filter plate 210, it will not affect the continued discharge of waste liquid into the sewage pipe. After the waste liquid is discharged, the filter plate 210 can be cleaned or replaced by the staff.

[0032] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the housing 100 is a rectangular frame, and the opening is also rectangular, with the edge of the opening located close to the edge of the housing 100. Positioning the opening edge as close to the edge of the housing 100 maximizes the use of the structural space of the housing 100, thus maximizing the opening size. Even when the screw extrusion truck 300 is discharging waste liquid at high speed, it ensures that the waste liquid smoothly enters the collection tank 110, preventing splashing or overflow due to excessive discharge speed.

[0033] A larger opening can better accommodate errors in the discharge position or angle of different equipment, improving the versatility and adaptability of the unloading device. This also reduces waste liquid spillage caused by misalignment of equipment.

[0034] Furthermore, the rectangular shell 100 and the rectangular opening structure are regular and easy to process, which is conducive to standardized production and assembly. It also facilitates the addition of reinforcing ribs or supporting structures at the edges, thereby improving overall strength.

[0035] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the outlet is located near a corner of the rectangular frame, and the bottom of the collection tank 110 slopes from the edge of the rectangular frame towards the outlet. This slope creates a natural flow gradient, ensuring that the waste liquid flows quickly and smoothly to the outlet under gravity, preventing stagnation. This effectively reduces the amount of waste liquid remaining at the bottom of the collection tank 110 and improves drainage efficiency.

[0036] Placing the outlet at a corner of the rectangular frame maximizes the sloping path, ensuring smooth drainage and maximizing gravity-based drainage for improved overall efficiency. This also avoids the potential for dead-angle residue buildup that could occur with outlets located in the center or sides of the rectangular frame.

[0037] In industrial production, corner locations are typically convenient for piping systems. Placing liquid outlets in corners simplifies external piping connections, improves space utilization, reduces pipe bends and intersections, and enhances the overall neatness and ease of maintenance of the equipment.

[0038] In one embodiment, exemplarily, such as Figure 1 , Figure 2As shown, the bottom of the collection chamber 110 is provided with a liquid outlet 120. The liquid outlet 120 is horizontally positioned, and the liquid outlet is located at the center of the liquid outlet 120. The filter plate 210 is detachably installed on the liquid outlet 120 and can cover the liquid outlet. The filter plate 210 is installed at the center of the liquid outlet 120 and aligned with the liquid outlet, so that the waste liquid is subjected to uniform force and flow rate when flowing through the filter plate 210, avoiding the phenomenon of flow deviation. This effectively improves the interception efficiency of solid particles such as drug residue and prevents fine particles from flowing around and entering the sewage pipe. The horizontal positioning of the liquid outlet 120 can form a uniform liquid surface distribution before the waste liquid enters the filter plate 210, avoiding uneven filtration or local blockage caused by tilting or local accumulation. The horizontal liquid outlet 120 puts the filter plate 210 in an easily observable and operable position, allowing operators to quickly determine whether the filter plate 210 needs to be cleaned or replaced.

[0039] The filter plate 210 is detachably installed on the liquid outlet 120, making operations such as cleaning the residue, replacing the filter plate 210, and maintaining the equipment more convenient and quick. In this embodiment, the installation method of the filter plate 210 is not limited. For example, the installation method of the filter plate 210 can be designed as a threaded connection, a snap-fit ​​connection, or a flange connection to adapt to different usage scenarios, as long as it can meet the usage requirements of this embodiment.

[0040] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the filter plate 210 includes a filtration section 211 and a fixing section 212, with the filtration section 211 located at the center of the filter plate 210. When the filter plate 210 is installed on the liquid outlet 120, the filtration section 211 abuts against the liquid outlet, and the area of ​​the filtration section 211 is S1, while the area of ​​the liquid outlet is S2, satisfying: S1 > S2. The larger area of ​​the filtration section 211 than the area of ​​the liquid outlet means that the waste liquid has a larger contact area during filtration, which can increase the amount of liquid filtered per unit time and avoid liquid flow blockage or overflow caused by insufficient filtration area. The larger filtration section 211 can also disperse the waste liquid flow rate, reducing the concentrated accumulation of impurities such as drug residue directly above the liquid outlet, thereby reducing the risk of local blockage and improving overall filtration stability.

[0041] Furthermore, the filter section 211 not only covers the outlet itself but also the surrounding edge area, creating a wider contact surface between the filter plate 210 and the outlet, improving sealing and preventing unfiltered waste liquid from flowing around. Even if some filtration areas become clogged due to residue accumulation, the larger filtration area ensures sufficient area remains for waste liquid filtration, preventing the entire filter plate 210 from failing completely, extending its service life, reducing replacement frequency, and improving the reliability of waste liquid filtration in this embodiment.

[0042] The fixing part 212 is used to stably install the filter plate 210 on the liquid outlet part 120, while the filtration part 211 focuses on the filtration function, realizing functional zoning and clear structure, and improving the installation accuracy and long-term stability of the filter plate 210.

[0043] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the liquid outlet 120 is a rectangular plate, with limit posts 220 at at least two opposite corners. The fixing part 212 has corresponding limit holes, and the limit posts 220 are inserted into these holes with an interference fit. By inserting the limit posts 220 into the limit holes, the filter plate 210 is guided to automatically align with the center of the liquid outlet, avoiding offset or misalignment caused by manual installation errors. The limit posts 220 at the two opposite corners of the rectangular plate ensure a unique and correct installation direction, preventing the filter plate 210 from being installed upside down or rotated, thus improving installation reliability and error prevention.

[0044] The limiting post 220 and the limiting hole are fitted with an interference fit, which enhances the connection rigidity between the filter plate 210 and the liquid outlet 120, preventing the filter plate 210 from loosening, shifting, or falling off during waste liquid impact or vibration. After the filter plate 210 is positioned by the limiting post 220, its filtration part 211 can more stably fit the edge of the liquid outlet, which helps to improve the sealing between the filter plate 210 and the liquid outlet 120, preventing unfiltered waste liquid from entering the sewage pipe.

[0045] The insertion structure of the limiting post 220 and the limiting hole allows for quick disassembly and installation of the filter plate 210 without the need for complex tools, facilitating daily cleaning of medicinal residues or replacement of clogged filter plates 210. When filtering discharged wastewater using this embodiment, different medicinal residues have different particle sizes, requiring filter plates 210 of different specifications. In this embodiment, the filter plate 210 is installed via the limiting post 220 and the limiting hole, enabling convenient and quick replacement when needed, thus improving the practicality of this embodiment.

[0046] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, a support portion 130 is provided on the side of the housing 100 away from the liquid collection tank 110. The support portion 130 is horizontally positioned to ensure that the housing 100 can be placed stably in the installation position. The horizontal positioning of the support portion 130 provides a stable support surface for the housing 100, allowing it to be placed stably on the ground, bracket, or equipment platform, preventing tilting, swaying, or overturning due to a shift in the center of gravity. As a support structure, the support portion 130 evenly distributes the weight of the housing 100 to multiple support points, preventing structural deformation or damage due to excessive local stress.

[0047] Please continue reading. Figure 1 , Figure 2For example, this embodiment also provides a residue treatment device, including a screw extrusion trolley 300, a track 400, and a liquid unloading device as described in any of the above embodiments. The screw extrusion trolley 300 is mounted on the track 400 and can move along the track 400; the liquid unloading device is disposed between the two tracks 400.

[0048] The dregs treatment equipment in this embodiment includes the unloading device in any of the above embodiments, and thus possesses all the beneficial effects of the unloading device, which will not be elaborated further here.

[0049] Based on the above, the unloading device is positioned between two rails 400, allowing the screw extrusion car 300 to automatically align with the opening of the unloading device during movement, achieving efficient, continuous, and leak-free waste liquid discharge. This reduces manual adjustment time and improves overall operational efficiency. Combined with the large opening design, inclined bottom, filter plate 210 filtration, and centralized discharge structure of the unloading device, it can handle waste liquid output from the screw extrusion car 300 at any discharge speed, preventing splashing or overflow and enhancing operational safety.

[0050] Furthermore, embedding the unloading device between the two 400-meter tracks maximizes space utilization and avoids additional space occupation.

[0051] In one embodiment, for example, a liquid outlet 310 is provided at one end of the screw extrusion cart 300. The projected area of ​​the liquid outlet 310 in the vertical direction is S3, and the projected area of ​​the opening on the liquid collection tank 110 in the vertical direction is S4, satisfying that S3 < S4. Since the area of ​​the liquid outlet 310 is smaller than the opening area of ​​the liquid collection tank 110, even if the screw extrusion cart 300 has slight displacement or positioning error during movement, it can ensure that the liquid outlet 310 is always within the opening coverage area, avoiding leakage of waste liquid. This improves the alignment tolerance and installation flexibility of this embodiment, and is particularly suitable for semi-automatic or manual operation scenarios. Of course, this embodiment can also make the unloading device compatible with screw extrusion carts 300 of different sizes or with slightly different positions of the liquid outlet 310, improving the versatility and adaptability of the equipment.

[0052] In one embodiment, for example, the screw extrusion cart 300 moves along the track 400 in a first direction. The length of the screw extrusion cart 300 in the first direction is L1, and the length of the opening on the liquid collection tank 110 in the first direction is L2, satisfying: L1 < L2. The opening length of the liquid collection tank 110 is greater than the overall length of the screw extrusion cart 300, ensuring that the liquid outlet 310 remains within the opening's coverage area throughout the entire movement of the screw extrusion cart 300 along the track 400. This achieves continuous and uninterrupted liquid discharge, preventing interruptions in discharge or leakage of waste liquid due to equipment movement.

[0053] In actual operation, the screw extrusion vehicle 300 may experience inertial offset or positioning error during startup and shutdown. The opening length of the liquid collection chamber 110 is greater than the overall length of the screw extrusion vehicle 300, meaning that the liquid collection chamber 110 provides sufficient tolerance space to ensure that even if the position of the screw extrusion vehicle 300 is slightly off, the liquid discharge task can still be completed smoothly.

[0054] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
