Description

Technical Field

[0001] This utility model belongs to the technical field of aquaculture systems, and in particular relates to a solid-liquid separation device for sewage discharge in aquaculture systems. Background Technology

[0002] A livestock farming system is a comprehensive management system encompassing multiple core components aimed at improving the efficiency, management level, and product quality of livestock or aquaculture. These core components are typically integrated into a livestock farming management system, using software platforms or hardware devices to help farm owners or managers better manage and monitor farm operations.

[0003] Currently, in the aquaculture process, sieves or various types of filters with built-in perforated mesh are commonly used to filter solid impurities in liquid media, or solid-liquid separation is achieved through equipment based on the principle of centrifugation.

[0004] However, existing solid-liquid separation equipment lacks an effective automatic removal mechanism after accumulating a certain amount of solid waste, causing this solid waste to remain inside the equipment for extended periods. This situation can easily lead to the solid waste mixing and settling with sludge from industrial wastewater, thereby reducing the liquid discharge efficiency of the solid-liquid separator. Manually disassembling the solid-liquid separator to clean this solid waste is not only time-consuming but also increases labor costs. Therefore, based on the above problems, we designed a solid-liquid separation device for wastewater discharge in aquaculture systems. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a solid-liquid separation device for wastewater discharge in aquaculture systems. This device addresses the technical problem that existing solid-liquid separation devices lack an effective automatic cleaning mechanism, and manual cleaning consumes a significant amount of time, increases labor costs, and reduces solid-liquid separation efficiency.

[0006] To achieve the above objectives, according to an embodiment of the first aspect of this utility model, a wastewater solid-liquid separation device for an aquaculture system is provided, comprising a base, a support platform disposed within the port of the base, and an extrusion mechanism;

[0007] The extrusion mechanism includes a hydraulic cylinder disposed on the top surface of the base, a pressure column disposed in the port of the base and connected to the hydraulic cylinder rod, and a pressure plate connected to the bottom surface of the pressure column;

[0008] Also includes:

[0009] A solid-liquid separation tank is installed inside the port of the base. Rotary columns are connected to both sides of the solid-liquid separation tank. The rotating columns are rotatably connected to the inner wall of the base through bearings. Multiple sets of filter holes are provided on the outer wall surface of the solid-liquid separation tank. A liquid holding vessel is provided on the surface of the support base, and a liquid guide port is provided on the side of the liquid holding vessel.

[0010] A further improvement is that a scraper ring is fitted around the edge of the pressure plate, and after the pressure plate extends into the solid-liquid separation tank, the scraper ring contacts the inner wall of the solid-liquid separation tank.

[0011] A further improvement is that the spacing and diameter of the filter holes in each group are the same.

[0012] A further improvement is that a lifting cylinder is provided inside the support base, and a pressure plate is connected to the top surface of the rod of the lifting cylinder, and the liquid container is connected to the pressure plate.

[0013] A further improvement is that a pair of supports are installed on the outside of the solid-liquid separation tank, and a vibrator is installed on each support.

[0014] A further improvement is that a speed reducer is externally connected to the base, and the output shaft of the speed reducer is connected to a rotating column on one side of the solid-liquid separation tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) This utility model uses a lifting cylinder to ensure the pressure plate and liquid container are tightly fitted to the bottom of the solid-liquid separation tank, providing stable support for subsequent squeezing operations. Next, the waste to be treated is poured into the solid-liquid separation tank. Subsequently, the hydraulic cylinder is activated to drive the pressure column and pressure plate downwards until the pressure plate is in close contact with the waste at the bottom of the tank. The applied pressure forces the liquid in the waste to be discharged through the filter holes and collected in the liquid container below, making operation more convenient.

[0017] (2) When the amount of waste in the solid-liquid separation tank reaches a certain level, the height of the liquid container is lowered by starting the lifting cylinder, and the pressure plate and scraper ring are moved up and down by the hydraulic cylinder. The scraper ring scrapes along the inner wall of the solid-liquid separation tank to effectively remove the residual waste, thereby reducing the difficulty and burden of subsequent manual cleaning.

[0018] (3) This utility model starts the reducer, which drives a pair of rotating columns to rotate, thereby tilting the solid-liquid separation tank. At the same time, the vibrator is turned on to generate high-frequency vibration, which helps to discharge the solid matter in the solid-liquid separation tank. This design not only simplifies the solid waste cleaning process and reduces the intensity of manual intervention, but also significantly improves the efficiency of solid-liquid separation, achieving the effect of saving time and effort.

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figure 1 and Figure 2 As shown, a wastewater solid-liquid separation device for an aquaculture system includes a base 1, a support platform 11 disposed in the port of the base 1, and a squeezing mechanism.

[0029] Specifically, the extrusion mechanism includes a hydraulic cylinder 14 disposed on the top surface of the base 1, a pressure column 13 disposed in the port of the base 1 and connected to the rod of the hydraulic cylinder 14, and a pressure plate 15 connected to the bottom surface of the pressure column 13. By activating the hydraulic cylinder 14, the pressure column 13 and the pressure plate 15 are driven downward until the pressure plate 15 comes into close contact with the bottom of the tank discharge. The applied pressure can be used to force the liquid in the discharge through the filter hole 22 to achieve solid-liquid separation.

[0030] like Figures 1 to 3As shown, the implementation includes: a solid-liquid separation tank 2, which is set inside the port of the base 1. Both sides of the solid-liquid separation tank 2 are connected to rotating columns 21. The rotating columns 21 are rotatably connected to the inner wall of the base 1 through bearings. The outer wall surface of the solid-liquid separation tank 2 is provided with multiple sets of filter holes 22. The spacing and diameter of each set of filter holes 22 are the same, thus forming multiple layers. This facilitates the squeezing of each layer of sewage after it is put in, thereby achieving solid-liquid separation. The surface of the support base 11 is provided with a liquid container 3. The side of the liquid container 3 is provided with a liquid guide port 31. The liquid container 3 is used to collect the discharged sewage.

[0031] It should be noted that the liquid container 3 is made of metal and can withstand a certain amount of pressure. It is an open type. When in use, the external pipeline is connected to the liquid outlet 31 to pump out and treat the sewage.

[0032] Specifically, as a preferred embodiment, a scraper ring 16 is fitted around the edge of the pressure plate 15. It should be noted that the liquid container 3 is made of metal. After the pressure plate 15 is inserted into the solid-liquid separation tank 2, the scraper ring 16 contacts the inner wall of the solid-liquid separation tank 2. The scraper ring 16 is designed to scrape off or remove residual waste from the inner wall of the solid-liquid separation tank 2.

[0033] Specifically, in a preferred embodiment, a lifting cylinder 101 is provided inside the support base 11. A pressure plate 102 is connected to the top surface of the rod of the lifting cylinder 101. The liquid container 3 is connected to the pressure plate 102. By activating the lifting cylinder 101, the pressure plate 102 and the liquid container 3 are tightly fitted to the bottom of the solid-liquid separation tank 2, providing stable support for subsequent squeezing operations. When emptying solid waste, the lifting cylinder 101 is activated again to lower the height of the liquid container 3.

[0034] like Figure 3 As shown, in this embodiment, a pair of brackets 41 are also installed outside the solid-liquid separation tank 2, and a vibrator 4 is installed on each bracket 41. The vibrator 4 is used to assist the solid in the solid-liquid separation tank 2 in pouring out.

[0035] like Figures 1 to 3 As shown in this embodiment, it should also be noted that before implementation, a reducer 12 is connected to the outside of the base 1. The output spindle of the reducer 12 is connected to the rotating column 21 on one side of the solid-liquid separation tank 2. The reducer 12 can be selected as BKV100, which is a commercially available product of the prior art, and its working principle has been disclosed.

[0036] Additionally, it should be noted that this application only addresses the shortcomings of existing solid-liquid separation equipment, such as the lack of an effective automatic cleaning mechanism, the significant time-consuming and labor-intensive manual cleaning, and the reduced efficiency of solid-liquid separation. It does not cover other aspects. The working principle of this solid-liquid separation equipment for wastewater discharge in aquaculture systems is described below:

[0037] In use, the operator activates the lifting cylinder 101, causing the pressure plate 102 to fit tightly against the bottom of the liquid container 3 in the solid-liquid separation tank 2, providing stable support for subsequent squeezing operations. Next, the waste to be treated is poured into the solid-liquid separation tank 2. Subsequently, by activating the hydraulic cylinder 14, the pressure column 13 and pressure plate 15 are driven downwards until the pressure plate 15 is in close contact with the waste at the bottom of the tank. The applied pressure forces the liquid in the waste to be discharged through the filter holes 22 and collected in the liquid container 3 below.

[0038] After one round of squeezing and separation, new waste is added to the solid-liquid separation tank 2, and the squeezing steps are repeated to ensure that the liquid continues to be discharged from the filter holes 22 at the preset height into the liquid container 3. When the waste in the solid-liquid separation tank 2 accumulates to a certain amount, the lifting cylinder 101 is activated again to lower the height of the liquid container 3, and the hydraulic cylinder 14 drives the pressure plate 15 and the scraper ring 16 to move up and down. The scraper ring 16 scrapes along the inner wall of the solid-liquid separation tank 2 to effectively remove residual waste.

[0039] Subsequently, the reducer 12 is started, and its output shaft drives a pair of rotating columns 21 to rotate, thereby tilting the solid-liquid separation tank 2. At the same time, the vibrator 4 is turned on to generate high-frequency vibration, which assists in the discharge of solid matter from the solid-liquid separation tank 2. This design not only simplifies the solid waste cleaning process and reduces the intensity of manual intervention, but also significantly improves the efficiency of solid-liquid separation, achieving time-saving and labor-saving effects.

[0040] The above embodiments are only used to illustrate the technical methods 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 methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
