[0002] After retrieving the patent document with the publication number of CN219663008U, the patent document drives the manure to move along the filter cylinder composed of the filter screen frame and the filter screen fixing frame through the spiral blade, filters the liquid contained in the manure by using the solid-liquid separation filter screen, and discharges it from the liquid discharge port arranged below the separation cylinder. When the filter screen needs to be cleaned, only need to open the sealing cover and spray clean water onto the surface of the filter screen frame from the observation port to wash the solid-liquid separation filter screen;

[0003] This patent document adds manure inside the separation cylinder and conducts solid-liquid separation through the spiral blade and the filter cylinder. However, there are hard particles such as sand and fiber in the manure, which are easy to wear the equipment when directly separated and processed with the manure. Moreover, there are large manure lumps that are easy to get stuck in the spiral blade, affecting the normal operation of the separation cylinder, and the solid-liquid distribution of the manure is uneven, affecting the separation efficiency.

[0024] As Figures 1 - 5 shown, a manure solid-liquid separation device for livestock and poultry breeding includes a separation cylinder 1, a cylinder cover 2 is inserted at the top of the separation cylinder 1, a spiral blade 3 is rotatably connected inside the separation cylinder 1, a filtrate cylinder 4 is sleeved outside the spiral blade 3, a first motor 5 is fixedly arranged at the input end of the spiral blade 3, and a pretreatment mechanism 6 for removing hard particles in the manure is further included.

[0025] In this embodiment: The pretreatment mechanism 6 includes a processing cylinder 601. The processing cylinder 601 is located on one side at the top of the separation cylinder 1. A feeding pipe is fixed to the top of the processing cylinder 601. A filter frame 602 for removing hard particles in the feces is provided at the bottom of the processing cylinder 601. A square hole for the filter frame 602 to enter and exit is formed in the outer wall of the processing cylinder 601. A second handle is fixed to one side of the filter frame 602. A rotating shaft 605 is provided above the filter frame 602. A stirring blade 604 is fixed to the bottom of the rotating shaft 605. A first bevel gear 606 is provided above the stirring blade 604. A second bevel gear 607 meshing with the first bevel gear 606 is provided on one side of the rotating shaft 605. A second motor 603 is fixedly arranged at the input end of the second bevel gear 607. An eccentric wheel 608 is provided above the first bevel gear 606. A hammer head 609 for crushing fecal lumps is sleeved on the top of the rotating shaft 605. A crushing groove matching with the hammer head 609 is formed in the top of the processing cylinder 601. The feeding pipe of the processing cylinder 601 communicates with the crushing groove. The top of the rotating shaft 605 is semi-spherical. The second motor 603 drives the second bevel gear 607 to rotate, thereby driving the first bevel gear 606 to rotate. The rotation of the first bevel gear 606 drives the rotating shaft 605 to rotate, thereby causing the eccentric wheel 608 and the stirring blade 604 to rotate. The rotation of the eccentric wheel 608 drives the outer hammer head 609 to perform eccentric motion in the crushing groove, thereby crushing the lumped feces. The crushed feces are stirred evenly by the rotation of the stirring blade 604. The hard particles in the stirred feces are filtered and removed by the filter frame 602.

[0026] In this embodiment: A feed pipe is fixed to one side at the top of the separation cylinder 1. A solid discharge pipe is fixed to the other side at the bottom of the separation cylinder 1. A liquid discharge pipe is provided on one side of the solid discharge pipe. Four first support columns are fixed to the bottom of the separation cylinder 1. A first handle is fixed to the top of the cylinder cover 2. A clamping groove is fixed to the bottom of the cylinder cover 2. A clamping strip matching with the clamping groove is fixed to the top of the filtrate cylinder 4. The bottom of the separation cylinder 1 communicates with the separation cylinder 1 through the feed pipe. Two second support columns are fixed to one side at the bottom of the separation cylinder 1. The feces are separated into solid and liquid by the spiral blade 3 and the filtrate cylinder 4. The filtrate cylinder 4 during separation is temporarily limited by the clamping strip at the top of the filtrate cylinder 4 and the clamping groove at the bottom of the cylinder cover 2. The cylinder cover 2 is removed by the first handle to clean the filtrate cylinder 4.

[0027] Working principle: The feces are fed into the crushing tank from the feeding port of the treatment cylinder 601. The second motor 603 is started to drive the second bevel gear 607 to rotate, which in turn drives the first bevel gear 606 to rotate. The rotation of the first bevel gear 606 drives the rotating shaft 605 to rotate, thereby causing the eccentric wheel 608 and the stirring blade 604 to rotate. The rotation of the eccentric wheel 608 drives the hammer head 609 on the outside to perform eccentric motion in the crushing tank, reducing the gap between the hammer head 609 and the crushing tank, squeezing and crushing the agglomerated feces. The stirring blade 604 stirs the crushed feces evenly. After being stirred evenly, the feces pass through the filter frame 602 to screen out hard particles and then enter the separation cylinder 1 through the feed pipe. The first motor 5 is started to drive the spiral blade 3 to rotate, which in turn drives the feces to move along the filtrate cylinder 4 to filter out the liquid contained in the feces, and the liquid is discharged from the liquid discharge pipe provided below the separation cylinder 1, while the dehydrated feces are discharged from the solid discharge pipe. During cleaning, the second handle is pulled to take out the filter frame 602 and remove the hard particles inside the filter frame 602. The first handle is pulled to move the cylinder cover 2 out, and the filtrate cylinder 4 is released from the limit. The filtrate cylinder 4 is rotated and water is sprayed on the surface of the filtrate cylinder 4 for cleaning.

[0028] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
