Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of solid-liquid separation treatment, in particular to a solid-liquid separation treatment equipment for bullfrog breeding waste. BACKGROUND

[0002] At present, the bullfrog breeding industry is developing rapidly, and the breeding scale is expanding. The waste treatment problem is becoming increasingly prominent. The bullfrog breeding waste is usually in a solid-liquid mixed state. If it is not properly treated, it will not only cause serious environmental pollution, but also breed a large number of bacteria, which will threaten the healthy growth of bullfrogs and affect the breeding efficiency. Therefore, efficient solid-liquid separation treatment of bullfrog breeding waste has become a key problem to be solved in the industry.

[0003] The traditional solid-liquid separation method of bullfrog breeding waste has many drawbacks. Some breeding farms use simple filter screen filtration method. This method can only separate out large particle solids, and it is difficult to effectively separate fine solid particles and water wrapped by solids, resulting in that the separated liquid still contains a lot of impurities, and the water content of the solid is also high. Subsequent treatment of such liquid and solid not only needs to invest a lot of resources and cost, but also the treatment effect is often unsatisfactory. When used for irrigation, the liquid containing a lot of impurities may block the sprinkler head, affecting the irrigation effect; and the solid with high water content is easy to produce odor during composting, and the fermentation process is slow, reducing the composting quality.

[0004] Although some more complex solid-liquid separation equipment improves the separation efficiency to some extent, it is usually complex in structure and high in cost. These devices usually need to be operated and maintained by professional personnel. For the majority of small and medium-sized bullfrog breeding farms, the purchase cost and operating cost are difficult to bear. In addition, the complex equipment has poor flexibility when facing bullfrog breeding waste with different characteristics, and cannot adjust the separation parameters in time according to the changes of the waste, resulting in unstable separation effect.

[0005] Some solid-liquid separation methods, such as natural sedimentation method, have low cost, but long time is needed, and the area occupied is large. Moreover, the separation effect is greatly affected by environmental factors, and there are many limitations in actual application. In addition, during the natural sedimentation process, the waste may emit a foul odor, which will have a bad influence on the environment around the breeding farm. SUMMARY

[0006] Technical problems solved: The traditional solid-liquid separation method of bullfrog breeding waste has many drawbacks. Some farms use simple filter screen filtering method, which can only separate large particles of solid, and it is difficult to effectively separate fine solid particles and water wrapped by solid, resulting in that the separated liquid still contains many impurities, and the water content of the solid is also high. Subsequent treatment of such liquid and solid not only needs to invest a lot of resources and cost, but also the treatment effect is often unsatisfactory. When used for irrigation, the liquid containing many impurities may block the spray head, affecting the irrigation effect; and the high water content of the solid is prone to produce odor during composting, and the fermentation process is slow, reducing the compost quality.

[0007] In view of the deficiencies of the prior art, the present application provides a bullfrog breeding waste solid-liquid separation treatment equipment, thereby solving the technical problems mentioned in the background art.

[0008] To achieve the above object, the present application is realized by the following technical scheme:

[0009] A bullfrog breeding waste solid-liquid separation treatment equipment, comprising a separation box, a separation mechanism is fixedly installed on the top of the separation box, the separation mechanism comprises a double-head motor, the double-head motor is fixedly installed on the top of the separation box, a first rotating shaft is fixedly installed on the bottom output end of the double-head motor, a rotating stirring blade is fixedly installed on the side wall of the first rotating shaft, a spiral body is fixedly installed on the side wall of the first rotating shaft, a filter barrel is arranged on the side wall of the spiral body, a first connecting cylinder is fixedly installed on the side wall of the filter barrel, and a second connecting cylinder is fixedly installed in the separation box.

[0010] In a possible implementation manner, the rotating stirring blade is located above the spiral body, the top of the filter barrel is fixedly installed with the inner wall of the upper end of the first connecting cylinder, and the spiral body is located in the first connecting cylinder.

[0011] In a possible implementation manner, the rotating stirring blade is located in the second connecting cylinder, the bottom plate is fixedly installed on the bottom of the first connecting cylinder, and the first material leakage pipe is fixedly installed on the bottom of the bottom plate.

[0012] In a possible implementation manner, a wedge-shaped circular ring is fixedly installed in the separation box, and the wedge-shaped circular ring is fixedly installed on the side wall of the first connecting cylinder.

[0013] In a possible implementation manner, a second material leakage pipe is fixedly installed in the wedge-shaped circular ring, and a feeding pipe is fixedly installed on the top of the separation box.

[0014] In a possible implementation manner, a synchronous belt transmission assembly is transmissionally installed on the output end of the double-head motor away from the first rotating shaft.

[0015] In a possible implementation, the second rotating shaft is fixedly installed on the side wall of the separation tank.

[0016] In a possible implementation, the second rotating shaft is fixedly installed on the side wall of the separation tank.

[0017] In a possible implementation, the second rotating shaft is fixedly installed on the side wall of the separation tank.

[0018] In a possible implementation, the second rotating shaft is fixedly installed on the side wall of the separation tank.

[0019] Compared with the prior art, the beneficial effects are as follows:

[0020] 1. In this scheme, the solid-liquid separation treatment equipment for bullfrog breeding waste exhibits excellent efficiency in solid-liquid separation. First, from the beginning of feeding, the equipment accurately guides the waste liquid into the second connecting cylinder through the feeding pipe, and then the rotating stirring blade rapidly stirs the waste liquid. By means of centrifugal force and shear force and impact force generated by the unique shape of the blade, the solids inside the waste liquid are completely dispersed, ensuring that the moisture inside the solids is fully exposed, creating favorable conditions for subsequent extrusion separation. Subsequently, the spiral body rotates in a counterclockwise manner, transmitting the waste liquid from top to bottom while performing strong extrusion, causing the dispersed solids to re-clump and efficiently extruding the internal waste water. Moreover, the equipment also increases the air pressure in the separation tank by blowing air into it through the rotating fan blade, further accelerating the flow of liquid, reducing the flow resistance of the liquid in the pore of the filter barrel and the gap between the solid particles, and at the same time promoting the moisture to overcome the surface tension and adhesion, more quickly separating from the inside of the solids. This multi-link closely coordinated design greatly improves the efficiency of solid-liquid separation. Compared with traditional solid-liquid separation methods, more waste can be processed in a shorter time, and the water content of the separated solids is significantly reduced, and the liquid is more clear, greatly improving the efficiency and quality of subsequent processing of solids and liquids respectively, effectively reducing the difficulty and cost of subsequent processing.

[0021] 2. In this scheme, the device integrates a series of complex processing procedures such as feeding, stirring, solid-liquid separation, air pressure assistance and solid discharge into one, showing significant advantages of multifunctional integration. From the structural point of view, the various components cooperate closely, and the space layout is compact and reasonable, greatly reducing the required floor area of the device. For a limited space bullfrog farm, this feature is particularly important. In terms of function, the integrated design makes the entire processing process smooth and coherent, eliminating the need for cumbersome material transfer between different devices, avoiding problems such as leakage and blockage that may occur in intermediate links, improving the stability and reliability of the device operation. The farm does not need to purchase multiple devices with different functions, reducing the initial investment cost, and also reducing the complexity of device maintenance and management. This multifunctional integrated design not only improves the processing efficiency, but also provides a one-stop solution for bullfrog farming waste treatment, fully improving the automation and convenience of waste treatment in the farm, adapting to the demand of modern farming industry for efficient and environmentally friendly waste treatment.

[0022] 3. In this scheme, the device has the outstanding feature of simple and flexible operation, bringing great convenience to the operator. The core control of the device is the double-head motor, which can easily realize different processing stages by simply switching the forward and reverse rotation of the double-head motor. When solid-liquid separation is needed, the motor is started to drive the rotating stirring blade and the screw to rotate counterclockwise, completing the stirring, extrusion and liquid separation of the waste. When the solid-liquid separation is completed and the solid needs to be discharged, the motor is simply switched to clockwise rotation, and the screw can break the solid clump structure and discharge the solid. This simple and clear operation method does not require the operator to have complex professional skills and knowledge, reducing personnel training costs and operation threshold. At the same time, the flexible motor control method enables the device to be adjusted in real time according to the actual waste processing capacity and processing rhythm. Whether it is large-scale continuous waste treatment or intermittent operation according to the breeding cycle, the device can quickly respond to different processing needs, further improving the practicality and adaptability of the device, making it a powerful tool for bullfrog farm waste treatment.

[0032] The technical solution in the embodiments of the present application is to solve the problems in the above background art, and the general idea is as follows:

[0033] Embodiment:

[0034] Please refer to Figures 1 to 6 As shown in the drawings, the present embodiment introduces the specific structure of a solid-liquid separation treatment equipment for bullfrog breeding waste, which comprises a separation tank 11. When in use, waste liquid is added into the inside of the second connecting cylinder 18 from the material inlet pipe 24, and the double-head motor 12 is simultaneously opened. The double-head motor 12 is fixedly installed at the top of the separation tank 11. The double-head motor 12 drives the first rotating shaft 13 to rotate counterclockwise. The double-head motor 12 is fixedly installed at the output end of the bottom. The first rotating shaft 13 drives the rotating stirring blade 14 to rotate counterclockwise. The first rotating shaft 13 is fixedly installed with the rotating stirring blade 14 on the side wall. The rotating stirring blade 14 stirs the waste liquid and disperses the solid in the waste liquid, which facilitates subsequent extrusion of water in the solid. The rotating stirring blade 14 is located above the helical body 15. The broken waste liquid will flow along the inner wall of the second connecting cylinder 18 to the inside of the filter barrel 16. The first rotating shaft 13 is fixedly installed with the helical body 15 on the side wall. At this time, the first rotating shaft 13 drives the helical body 15 to rotate counterclockwise.

[0035] The spiral body 15 is provided with a filter barrel 16, and the spiral body 15 rotates counterclockwise to transmit the waste liquid flowing into the filter barrel 16 from top to bottom, and the spiral body 15 extrudes the waste liquid to re-extrude the dispersed solid and extrude the internal waste water, the first connecting barrel 17 is fixedly installed on the side wall of the filter barrel 16, the waste water is discharged into the first connecting barrel 17 from the filter barrel 16, and then falls onto the top of the bottom plate 19 for collection, the top of the filter barrel 16 is fixedly installed with the inner wall of the upper end of the first connecting barrel 17, and finally the first material leakage pipe 21 is opened to discharge the waste water in the device, the spiral body 15 is located in the first connecting barrel 17, and the synchronous belt transmission assembly 25 is driven counterclockwise by the double-head motor 12, the second connecting barrel 18 is fixedly installed in the separation tank 11, the second rotating shaft 26 is driven counterclockwise by the synchronous belt transmission assembly 25, the rotating fan blade 27 is located in the second connecting barrel 18, the second rotating shaft 26 drives the rotating fan blade 27 to make counterclockwise circular motion, and the bottom plate 19 is fixedly installed on the bottom of the first connecting barrel 17, so that air is transmitted into the separation tank 11 through the L-shaped connecting pipe 28 under the action of the rotating fan blade 27, the pressure in the separation tank 11 is increased, the flow speed of the liquid is increased, and the speed of the waste water separated from the solid is increased;

[0036] The bottom plate 19 is fixedly installed with the first material leakage pipe 21, when the double-head motor 12 rotates clockwise, the first rotating shaft 13 is driven clockwise by the double-head motor 12, the wedge-shaped ring 22 is fixedly installed in the separation tank 11, the spiral body 15 is driven clockwise by the first rotating shaft 13, the wedge-shaped ring 22 is fixedly installed on the side wall of the first connecting barrel 17, the spiral body 15 destroys the solid mechanism of the clumped solid in the filter barrel 16, and the solid in the filter barrel 16 is discharged, the second material leakage pipe 23 is fixedly installed in the wedge-shaped ring 22, the solid in the filter barrel 16 is transmitted to the gap between the first connecting barrel 17 and the second connecting barrel 18, flows to the inside of the separation tank 11 along the inclined surface of the first connecting barrel 17, is collected at the second material leakage pipe 23 through the inclined surface of the wedge-shaped ring 22, is discharged from the inside of the separation tank 11 through the second material leakage pipe 23, and separation of the solid and the liquid in the separation tank 11 is completed, the top of the separation tank 11 is fixedly installed with the feeding pipe 24, the synchronous belt transmission assembly 25 is transmissionally installed at the output end away from the first rotating shaft 13 of the double-head motor 12, the second rotating shaft 26 is transmissionally installed at one end away from the double-head motor 12 of the synchronous belt transmission assembly 25, the rotating fan blade 27 is fixedly installed on the side wall of the second rotating shaft 26, the L-shaped connecting pipe 28 is fixedly installed on the side wall of the separation tank 11, the rotating fan blade 27 is located in the L-shaped connecting pipe 28, and the bracket 29 is fixedly installed on the side wall of the separation tank 11.

[0037] Working principle: feed positioning: before the equipment starts, the mixed waste produced by bullfrog breeding is accurately introduced into the second connecting cylinder 18 in the separation box 11 in the form of waste liquid through the feed pipe 24. The design of the feed pipe 24 is to ensure that the waste can directly enter the designated processing area, avoid spilling and disordered flow, and lay the foundation for subsequent processing. At the same time, the double-head motor 12 at the top of the separation box 11 is started. The output shaft at the bottom of the double-head motor 12 drives the first rotating shaft 13 to rotate counterclockwise by virtue of close connection. The rotating stirring blade 14 fixed on the side wall of the first rotating shaft 13 rotates synchronously. The rotating stirring blade 14 forms a stirring flow field in the waste liquid in the second connecting cylinder 18. Its stirring action is based on centrifugal force and blade shape design. The waste liquid is pushed by the blade, so that the internal solid particles are subjected to shear force and impact force. When the blade contacts the solid particles, the shear force generated by the flow rate difference at different positions tears the larger solid block, for example, the blocky feces is gradually broken into smaller particles under the action of shear force. The rotating blade drives the liquid to move at high speed, and the impact force generated by the rotating blade impacts the solid, further breaking the solid structure. The two forces work together to break up the solid, so that the water inside the solid has the opportunity to be exposed, which is convenient for subsequent extrusion separation. The rotating stirring blade 14 is arranged above the spiral body 15, which ensures that the solid is fully dispersed before the waste liquid enters the spiral body 15 for processing, optimizing the preconditions for solid-liquid separation.

[0038] The stirred and dispersed waste liquid naturally slides along the inner wall of the second connecting cylinder 18 to the inside of the filter barrel 16 due to gravity and stirring power. At this time, the first rotating shaft 13 drives the spiral body 15 to rotate counterclockwise. The spiral structure of the spiral body 15 is designed with optimized parameters such as pitch and helix angle. When the spiral body 15 rotates, the substances in the waste liquid move from top to bottom along the spiral surface under the push of the spiral surface, realizing the orderly transmission of the waste liquid in the filter barrel 16. In the transmission process, the distance between the outer surface of the spiral body 15 and the inner wall of the filter barrel 16 gradually decreases, generating extrusion force on the waste liquid. At the same time, the centrifugal force generated by the rotation of the spiral body makes the solid particles close to the inner wall of the filter barrel 16, further enhancing the extrusion force. Under the action of the double effect, the dispersed solid reaggregates and forms a mass. The water in the solid and the gap between the particles is forced to be squeezed out under pressure. The filter barrel 16, as a key component, has a filtering function on its side wall, which can allow liquid to pass through and block solid particles. The squeezed waste water passes through the side wall of the filter barrel 16 and flows into the first connecting cylinder 17 fixed thereto. The internal space of the first connecting cylinder 17 is designed reasonably, which can effectively collect waste water and guide it to flow downward. The waste water falls from the first connecting cylinder 17 to the top of the bottom plate 19 under the action of gravity and is temporarily stored. The surface of the bottom plate 19 is smooth and inclined, guiding the waste water to flow to the first discharge pipe 21. When the first discharge pipe 21 is opened, the waste water is discharged from the equipment under the action of gravity, completing the liquid separation and discharge. The spiral body 15 is inside the first connecting cylinder 17, ensuring that the extrusion and filtration processes are closely connected, improving the efficiency of solid-liquid separation.

[0039] Air pressure generation: while the solid-liquid separation main process is in progress, the other output end of the double-head motor 12 drives the second rotating shaft 26 to rotate counterclockwise through the synchronous belt transmission assembly 25, which is composed of a driving wheel, a driven wheel and a synchronous belt. The transmission ratio is accurately designed to ensure that the rotation speed of the second rotating shaft 26 is adapted to the solid-liquid separation process. The second rotating shaft 26 drives the rotating fan blade 27 fixed on its side wall to move counterclockwise in a circular motion. The blade shape of the rotating fan blade 27 is airfoil-shaped. When rotating, a pressure difference is generated between the upper and lower surfaces of the blade, just like the principle of a fan, which sucks air from one end of the L-shaped connecting pipe 28 and forcefully pushes it into the separation tank 11. The air entering the separation tank 11 increases the internal air pressure. This air pressure change has multiple positive effects on solid-liquid separation. The increased air pressure provides additional power for liquid flow, reduces the flow resistance of the liquid in the pores of the filter barrel 16 and the gap between solid particles, makes the wastewater pass through the filter barrel 16 into the first connecting cylinder 17 more quickly, improves the separation speed, and the air pressure acts on the solid particles, further extruding the solid, helping the water to overcome the surface tension and adhesion, accelerating the speed of water from the inside of the solid, improving the solid-liquid separation effect, and making the solid contain less water;

[0040] When the solid-liquid separation is completed and the solid needs to be discharged, the double-head motor 12 changes the rotation direction to clockwise, the first rotating shaft 13 rotates clockwise synchronously with the double-head motor 12, and in turn drives the spiral body 15 to rotate clockwise. The spiral body 15 rotating clockwise has the opposite effect on the solidified solid compared to when it rotates counterclockwise. The rotation of the spiral body 15 and the friction between the spiral surface and the solid break the connection structure between the solids, making the solidified solid loose again and facilitating discharge.

[0041] The solid with the damaged structure is transmitted from the inside of the filter barrel 16 to the gap between the first connecting cylinder 17 and the second connecting cylinder 18 under the push of the spiral body 15. The side wall of the first connecting cylinder 17 is designed to be inclined. The solid slides down to the inside of the separation tank 11 under the action of gravity and the push of the spiral body. The wedge-shaped ring 22 installed on the side wall of the first connecting cylinder 17 guides the flow direction of the solid. The solid flows along the inclined surface of the wedge-shaped ring 22 and collects at the second discharge pipe 23 inside it. The diameter of the second discharge pipe 23 is matched with the size of the solid particles to ensure that the solid can pass through smoothly and finally be discharged from the separation tank 11, completing the solid discharge process and realizing the complete solid-liquid separation treatment of the discarded material of bullfrog breeding by the equipment.

[0042] It should be noted that the above-mentioned embodiments are merely used to clearly illustrate the technical solutions of the present application, and should not be construed as limitations to the present application. Based on the above-mentioned embodiments, those skilled in the art can make other variations or modifications without departing from the spirit of the present application.
