Description

Technical Field

[0001] This utility model belongs to the field of fecal solid-liquid separation technology, specifically relating to a fecal solid-liquid separation device. Background Technology

[0002] Feces are the undigested substances remaining after the food of humans or animals has been digested and absorbed. Feces generally contain about 25% water, with the remainder consisting mostly of protein, inorganic matter, fat, undigested dietary fiber, dehydrated digestive juice residue, and vitamins K and B. Currently, in the livestock industry, feces have become a major culprit in environmental pollution. However, animal feces are also excellent fertilizer. Animal feces are a mixture of solid and liquid. If the solid and liquid in the feces are separated, the liquid can be used as fertilizer, and the solid can be used directly as fuel or dried and carbonized into pellets at a high temperature of 300°C for use as fuel. Currently, most methods of treating feces involve leaving the feces for a period of time to allow the solids to settle, and then draining the upper liquid layer to separate the solids. This method is time-consuming and reduces the efficiency of feces treatment. Therefore, a feces solid-liquid separation device is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a fecal solid-liquid separation device, which adds a fecal mixture to a conveying cylinder through a feed hopper, and conveys the fecal mixture through an auger. When the fecal mixture passes through the conveying cylinder, the liquid in the fecal mixture flows into a storage tank through a filter hole, thereby realizing the solid-liquid separation of the fecal mixture and improving the processing efficiency of fecal solid-liquid separation.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A fecal solid-liquid separation device includes a storage tank, a plurality of linearly distributed conveying cylinders installed on the upper side of the storage tank, baffles fixedly provided on both the left and right sides of the plurality of conveying cylinders, a circular shaft rotatably mounted inside the plurality of conveying cylinders, a plurality of rotating holes matching the circular shafts provided on the baffles, an auger matching the conveying cylinders fixedly provided on the sidewalls of the plurality of circular shafts, a plurality of linearly distributed filter holes provided on the lower side of the plurality of conveying cylinders, a discharge port provided on the right side of the plurality of conveying cylinders, a feed port provided on the left side of the plurality of conveying cylinders, a feed hopper matching the feed port fixedly provided on the upper side of the plurality of conveying cylinders, and a feeding assembly matching the feed hoppers fixedly provided on the upper side of the storage tank.

[0006] The feeding assembly includes a storage bin installed on the upper side of the storage pool. The lower side of the storage bin has several discharge ports that match the feed hopper. Two linearly distributed round rods are rotatably mounted on the front and rear sides of the storage bin. Each of the four round rods is concentrically fixed with a sprocket. The two sprockets located on the same side are jointly mounted with a chain. The front and rear side walls of the storage bin have annular openings that match the chain. Several linearly distributed push plates are jointly fixed between the two chains. A motor is installed on one side of the storage bin. The output shaft of the motor is drivenly connected to one of the round rods. The two round rods on the left side are jointly provided with transmission components that match several round shafts.

[0007] The transmission component includes a transmission shaft rotatably mounted on the lower side of the storage bin, two round rods on the left side are concentrically fixed with first pulleys, and second pulleys are concentrically fixed on the front and rear sides of the transmission shaft. A belt is provided between the first pulleys and the adjacent second pulleys.

Detailed Implementation

[0019] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-5 As shown, the present invention discloses a fecal solid-liquid separation device, comprising a storage tank 1, a plurality of linearly distributed conveying cylinders 10 installed on the upper side of the storage tank 1, baffles 11 fixed on both the left and right sides of the plurality of conveying cylinders 10, a circular shaft 12 rotatably assembled inside the plurality of conveying cylinders 10, a plurality of rotating holes matching the circular shaft 12 on the baffles 11, an auger 13 matching the conveying cylinders 10 fixed on the sidewalls of the circular shafts 12, a plurality of linearly distributed filter holes 14 on the lower side of the plurality of conveying cylinders 10, a discharge port on the right side of the plurality of conveying cylinders 10, a feed port on the left side of the plurality of conveying cylinders 10, a feed hopper 15 matching the feed port fixed on the upper side of the plurality of conveying cylinders 10, and a feeding assembly matching the feed hopper 15 fixed on the upper side of the storage tank 1.

[0021] In use, the feeding assembly adds the fecal mixture into the feed hopper 15, and the fecal mixture flows into the conveying cylinder 10 through the feed hopper 15. The auger 13 in each conveying cylinder 10 rotates and conveys the fecal mixture into the conveying cylinder 10 to the other end of the conveying cylinder 10. During the conveying process of the fecal mixture by the auger 13, when the fecal mixture is conveyed to the upper side of the filter hole 14, the liquid in the fecal mixture flows into the storage tank 1 through the filter hole 14, and the other feces are conveyed to the other side of the conveying cylinder 10 through the auger 13 and discharged through the discharge port, so that the fecal mixture can quickly achieve solid-liquid separation and shorten the processing time of the feces.

[0022] This invention adds a mixture of feces to a conveying cylinder through a feed hopper, and then conveys the mixture through an auger. As the mixture passes through the conveying cylinder, the liquid in the mixture flows into a storage tank through a filter hole, thereby achieving solid-liquid separation of the feces mixture and improving the processing efficiency of solid-liquid separation of feces.

[0023] The feeding assembly includes a storage bin 20 installed on the upper side of the storage pool 1. The storage bin 20 has several discharge ports that match the feed hopper 15 on its lower side. The storage bin 20 has two linearly distributed round rods 21 rotatably mounted on its front and rear sides. All four round rods 21 are concentrically fixed with sprockets. The two sprockets on the same side at the front and rear are jointly mounted with chains 22. The storage bin 20 has annular openings 23 that match the chains 22 on its front and rear side walls. Several linearly distributed push plates 24 are jointly fixed between the two chains 22. A motor 25 is installed on one side of the storage bin 20. The output shaft of the motor 25 is connected to a round rod 21 for transmission. The two round rods 21 on the left side are jointly equipped with transmission components that match several round shafts 12.

[0024] When using this invention, the user directly pours the fecal mixture into the storage bin 20. The output shaft of the motor 25 drives the round rod 21 to rotate continuously. The round rod 21 drives the chain 22 on the same side to rotate through the sprocket. The chain 22 drives the push plate 24 to move. The push plate 24 pushes the fecal mixture in the storage bin 20 to the discharge port. As the chain 22 rotates, the push plate 24 pushes the fecal mixture into the discharge port, and then into the conveying cylinder 10 through the feed hopper 15. There is no need to add the fecal mixture separately to each feed hopper 15, which improves the ease of use of this device.

[0025] The transmission components include a transmission shaft 30 rotatably mounted on the lower side of the storage bin 20, two round rods 21 on the left side are concentrically fixed with first pulleys 31, second pulleys 32 are concentrically fixed on the front and rear sides of the transmission shaft 30, belts 33 are provided between the first pulleys 31 and the adjacent second pulleys 32, and first bevel teeth 34 are concentrically fixed on the left side of several round shafts 12, and several second bevel teeth 35 that mesh with the first bevel teeth 34 are concentrically fixed on the transmission shaft 30;

[0026] In use, the output shaft of the motor 25 drives the round rod 21 to rotate. The round rod 21 drives the second pulley 32 to rotate via the first pulley 31 and the belt 33. The second pulley 32 synchronously drives the transmission shaft 30 to rotate. The transmission shaft 30 synchronously drives several second bevel teeth 35 to rotate. The second bevel teeth 35 drive the meshing first bevel teeth 34 to rotate. The first bevel teeth 34 synchronously drive the round shaft 12 to rotate. The round shaft 12 synchronously drives the auger 13 to rotate, thereby conveying the fecal mixture entering the conveying cylinder 10. By setting one motor 25 to synchronously drive several augers 13 and two chains 22 to rotate, the processing cost of the fecal mixture is reduced.

[0027] Each of the conveying cylinders 10 has a discharge plate 40 fixed on its right side to match the discharge port, which facilitates the discharge of materials from the conveying cylinders 10.

[0028] The storage bin 20 is equipped with several baffles 41 that match the discharge port to prevent the accumulation of fecal mixture and ensure the complete discharge of fecal mixture in the storage bin 20.

[0029] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
