Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, and more specifically, to a fecal solid-liquid separation device. Background Technology

[0002] After solid-liquid separation, livestock manure treatment equipment needs to be internally cleaned to prevent residue accumulation and bacterial growth. However, existing cleaning systems generally use a fixed-flow spray method, which cannot flexibly adjust the amount of cleaning solution according to the degree of internal contamination, the needs of the cleaning stage, or the water supply. This results in water waste when the contamination is mild and poor cleaning effect when the contamination is severe. Especially when multiple batches of materials need to be processed continuously or when dealing with manure of different concentrations, this single-flow mode increases operating costs and affects the hygiene standards and processing efficiency of the equipment.

[0003] In the process of adjusting and saving cleaning parameters, operators need to frequently adjust the cleaning fluid flow rate according to the actual working conditions to achieve the best cleaning effect. Traditional devices mostly rely on manual valves or simple flow controllers, which lack precise gear memory and quick locking functions. Each adjustment requires re-exploring the appropriate opening degree, which is time-consuming and makes it difficult to ensure the consistency of adjustment accuracy. In addition, manual operation is prone to flow setting deviations due to human error. It is impossible to establish standardized operating procedures for different cleaning modes, which reduces the automation level and ease of use of the equipment. Utility Model Content

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, the present invention provides a fecal solid-liquid separation device to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a fecal solid-liquid separation device, comprising a support frame, an installation shell fixedly disposed within the support frame, a sieve plate slidably disposed within the installation shell, a spiral plate rotatably disposed within the installation shell, an outer frame fixedly disposed at the top of the installation shell, a filter plate fixedly disposed at the bottom surface of the installation shell, a diversion pipe fixedly disposed on the outer wall of the outer frame, a nozzle fixedly disposed at the bottom surface of the diversion pipe, multiple sets of nozzles, a connecting sleeve fixedly disposed at the top of the diversion pipe, an adjusting sleeve rotatably disposed at the top of the connecting sleeve, and an outer connecting pipe rotatably disposed at the top of the adjusting sleeve. The sleeve has an inner movable groove, and a stop block is slidably provided in the movable groove. Multiple sets of stop blocks are provided, and a compression spring is connected between the outer wall of the stop block and the movable groove. An arc-shaped block is fixedly provided on the outer wall of the adjusting sleeve. A positioning sleeve is fixedly provided on the outer wall of the connecting sleeve. A positioning hole is provided on the outer wall of the positioning sleeve. Multiple sets of arc blocks are provided, and a return spring is connected to the inner side of each set. A positioning block is fixedly provided at the bottom of each set of return springs. An abutment block is fixedly provided at the top of each set of positioning blocks. The abutment blocks are slidably connected to the multiple sets of arc blocks. A limiting sleeve is slidably provided on the outer wall of the connecting sleeve. The limiting sleeve abuts against the top of the multiple sets of abutment blocks.

[0006] The present invention is further configured such that a motor is fixedly installed on the outer wall of the mounting shell, the output end of the motor is fixedly connected to the spiral plate, a collection box is provided inside the support frame, and a partition is fixedly installed inside the collection box. The motor drives the spiral plate to rotate continuously to realize the continuous transportation of feces and solid-liquid separation. The partition divides the collection box into independent solid and liquid collection areas to ensure that the separated solid and liquid are collected separately without interfering with each other.

[0007] The present invention is further configured such that guide blocks are fixedly provided on the bottom surface of multiple sets of the stop blocks, and guide grooves are provided in the movable grooves. Multiple sets of guide blocks and guide grooves are provided and slidably connected. The guide blocks slide precisely along the guide grooves to provide a stable radial movement trajectory for the stop blocks, effectively preventing the stop blocks from shifting laterally or getting stuck during the adjustment process. The coordinated action of multiple sets of guide blocks ensures the accuracy and repeatability of flow regulation.

[0008] The present invention is further configured such that a sliding rod is fixedly provided on the top surface of the limiting sleeve, and multiple sets of the sliding rod are provided, with limiting blocks fixed at their top ends and to the outside. A rotating plate is rotatably provided on the outer wall of the connecting sleeve, and a limiting hole is provided on the outer wall of the rotating plate. Multiple sets of limiting holes are provided, and each has an unlocking hole at one end. When the sliding rod is in the limiting hole, it forms a reliable axial constraint on the limiting sleeve to prevent accidental movement. Rotating the rotating plate moves the sliding rod along the limiting hole to the unlocking hole position, which can quickly release the restriction on the limiting sleeve, simplifying the unlocking operation process and improving the convenience of operation.

[0009] The present invention is further configured such that a guide block is fixedly provided on the inner side of the limiting sleeve, and a guide groove is provided on the outer wall of the connecting sleeve. Multiple sets of guide blocks and guide grooves are provided and slidably connected. The precise sliding cooperation between the guide blocks and guide grooves ensures that the limiting sleeve moves accurately and smoothly along the axial direction, effectively preventing the limiting sleeve from tilting or jamming during the lifting process, and improving the smoothness and reliability of unlocking and locking operations.

[0010] The present invention is further configured such that a tension spring is connected to the bottom surface of the rotating plate, and a thrust bearing is connected between the bottom end of the tension spring and the limiting sleeve. The tension spring provides a continuous reset tension to the limiting sleeve to realize the automatic unlocking function. The thrust bearing bears the axial thrust generated by the rotation of the rotating plate and reduces the friction and wear between the rotating plate and the limiting sleeve, ensuring that the rotation of the rotating plate is easy and flexible and extending its service life.

[0011] The present invention is further configured such that a bracket is fixedly provided on the inner side of the connecting sleeve. The bracket provides stable sliding guidance and support for the hexagonal rod, ensuring that the hexagonal rod moves accurately along the axial direction under the drive of the screw without deviation, ensuring that the transmission direction of the pushing force of the push block to the stop block is accurate, and improving the overall stability and adjustment accuracy of the flow regulating mechanism.

[0012] The present invention is further configured such that: a rotating ring is fixedly provided on the outer wall of the rotating plate; a sliding hole is provided on the inner side of the rotating ring; multiple sets of sliding holes are provided, and each set of the sliding holes has a stop block slidably provided on its inner side; a stop groove is provided on the outer wall of the connecting sleeve; multiple sets of stop grooves are provided, and each set of stop blocks abuts against multiple sets of stop blocks; a push spring is connected between each set of stop blocks and the sliding hole; a screw is threadedly connected to the inner side of the adjusting sleeve; a hexagonal rod is fixedly provided at the top of the screw; the hexagonal rod is slidably connected to the bracket, and a push block is fixedly provided at its top; multiple sets of ball bearings are rolled on the outer wall of the push block; the push spring pushes the stop block against the stop groove to provide a clear positioning node and rotational feedback for the rotating plate, preventing accidental rotation of the rotating plate and resulting in misoperation; the threaded engagement between the screw and the adjusting sleeve converts the rotational motion into the axial pushing motion of the hexagonal rod; the multiple sets of ball bearings on the outer wall of the push block push the stop block to move by rolling friction, significantly reducing the adjustment resistance and achieving precise and continuous flow regulation.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a fecal solid-liquid separation device, which has the following beneficial effects: 1. This device drives a hexagonal rod to move axially along the support through a screw threaded engagement between a rotating adjusting sleeve and a screw. Multiple sets of balls on the outer wall of the push block roll and push multiple sets of stops to slide within the movable groove, compressing the compression spring. By changing the flow cross-sectional area between the multiple sets of stops, precise and continuous adjustment of the cleaning fluid flow rate is achieved. The sliding engagement between the guide block and the guide groove ensures accurate movement of the stops and prevents jamming. This mechanism solves the problem that traditional fixed-flow spray systems cannot flexibly adjust according to the degree of equipment contamination and cleaning needs. Operators can adjust the cleaning fluid volume in real time according to actual working conditions. Reduce the flow rate to avoid water waste when the contamination is light, and increase the flow rate to improve the cleaning effect when the contamination is heavy. The rolling friction design of the balls greatly reduces the adjustment resistance, making operation easy and flexible. The threaded drive provides a stable and controllable propulsion force to ensure the accuracy and repeatability of flow adjustment, significantly improving the adaptability and resource utilization efficiency of the cleaning system.

[0014] 2. This device uses multiple sets of arc-shaped blocks fixed to the outer wall of the adjusting sleeve, with a return spring and a positioning block connected to the inner side. These work in conjunction with multiple positioning holes on the outer wall of the positioning sleeve. When the limiting sleeve abuts against the top of the multiple abutting blocks, the positioning block is accurately inserted into the positioning hole, achieving precise positioning of the adjusting sleeve and locking of the flow rate. This mechanism solves the problem of traditional manual adjusting systems lacking speed memory and quick locking functions, requiring repeated adjustments to find the appropriate opening. Multiple positioning holes correspond to different cleaning flow rates. Operators can preset standard flow rates according to common operating conditions and quickly switch between them. The mechanical cooperation between the positioning block and the positioning hole provides clear position feedback, ensuring consistent adjustment accuracy. After adjustment, the positioning block automatically locks to prevent flow rate setting drift due to vibration or accidental contact. Rotating the rotating plate releases the limiting sleeve via a tension spring, allowing for quick unlocking and flow rate adjustment. The return spring pushes the positioning block to automatically reset and enter the next speed range, significantly improving the automation level and ease of operation of the cleaning system.

[0015] 3. This device utilizes multiple sets of limiting holes on the outer wall of the rotating plate, along with multiple sets of sliding rods fixed to the top surface of the limiting sleeve. When the sliding rods are within the limiting holes, they restrict the limiting sleeve and prevent accidental movement. Multiple sets of sliding holes are opened on the inner side of the fixed rotating ring on the outer wall of the rotating plate to slide and set the stop blocks, which in turn cooperate with multiple sets of stop grooves on the outer wall of the connecting sleeve. Push springs push the stop blocks against the stop grooves to position the rotating plate. This mechanism solves the problem of decreased positioning accuracy and jamming caused by the lack of effective locking protection in traditional adjustment devices. The cooperation between the sliding rods and the limiting holes provides reliable axial constraint for the limiting sleeve, preventing the adjusted flow setting from drifting due to external forces. The cooperation between the stop blocks and stop grooves on the rotating plate provides clear position nodes and mechanical feedback for unlocking and locking operations. The thrust bearing reduces friction and wear between the rotating plate and the limiting sleeve. The sliding connection between multiple sets of guide blocks and guide grooves ensures accurate movement trajectory of the limiting sleeve. The rolling friction mechanism of the balls reduces wear between the push block and the stop block, significantly extending the service life of the adjustment mechanism, reducing maintenance frequency, and improving the long-term stability and reliability of the cleaning system.
