[0002] In recent years, with the large-scale and intensive development of livestock and poultry farming in my country, the amount of manure discharged from farms has increased dramatically, and has become one of the main sources of agricultural non-point source pollution. Traditional manure treatment methods, such as open-air stacking and direct return to the field, not only cause waste of resources, but also seriously pollute the environment and threaten human health. In order to achieve effective treatment of manure, it is necessary to separate solid impurities and sewage in manure.

[0003] Traditional manure and sewage treatment is mainly achieved by using a filter press. Manure and sewage are pressurized by a delivery pump and sent between two adjacent filter plates in the filter press. Impurities in the manure and sewage are intercepted between the two filter plates, and the manure and sewage are discharged through the filter plates. As the number of intercepted impurities increases, the impurities between the filter plates squeeze each other to achieve the effect of filter pressing. After that, the manure and sewage delivery work is stopped, the two adjacent filter plates are separated from each other, and the impurities between the filter plates that have been treated by filter pressing fall off, and the manure and sewage filter pressing work is completed. After that, the two filter plates are closed and the manure and sewage can be treated repeatedly. In the above process, the equipment needs to be in a shutdown state when the solid impurities are removed, so it cannot achieve the continuous treatment effect of manure and sewage, affecting efficiency.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 6As shown, a farm manure treatment device of the present invention comprises an outer box body 1, guide rails 2 are transversely arranged on both the front and rear sides of the inner wall of the outer box body 1, a plurality of movable frames 3 are arranged between the two guide rails 2, the plurality of movable frames 3 are transversely arranged along the length direction of the guide rails 2, the movable frames 3 are slidably mounted on the guide rails 2, two filter screens 4 are relatively arranged in the movable frame 3, and a water supply pipe 5 for supplying water between two adjacent movable frames 3 and a drainage pipe 6 for draining water filtered by the filter screen 4 are arranged on the movable frame 3; The left and right sides of the movable frame 3 can both be used for filter pressing. When one side of the movable frame 3 is in the filter pressing working state, the other side of the movable frame 3 is in the state of discharging filter pressing impurities.

[0020] In detail, the movable frame 3 can slide left and right on the guide rail 2. When the movable frame 3 is docked with another movable frame 3 on one adjacent side, the movable frame 3 and the other movable frame 3 on the other adjacent side are in a separated state, that is, the two adjacent movable frames 3 maintain a synchronous relative motion state. The two adjacent movable frames 3 in the docked state perform filter pressure treatment on the feces and sewage, and the two adjacent movable frames 3 in the separated state are in a working state of discharging filter pressure impurities. The outer box body 1 is used to support the guide rail 2 and multiple movable frames 3 thereon. The two filter screens 4 on the movable frame 3 are adapted to the two movable frames 3 on the left and right sides of the movable frame 3. The water supply pipe 5 is used to supply water between the two movable frames 3 in the docked state. The drainage pipe 6 is used to drain the water that passes through the filter screen 4.

[0021] When in use, the moving frame 3 moves toward the adjacent moving frame 3 on one side thereof and makes them dock with each other to form a group of filter press structures, so that multiple moving frames 3 can form multiple groups of filter press structures, and the pressurized feces and sewage are supplied to the filter press structure through the water supply pipe 5, and the feces and sewage in the filter press structure pass through the filter screen 4 and are discharged through the drain pipe 6, and the filter screen 4 will intercept the impurities in the feces and sewage in the filter press structure. With the increase of impurities and the pressurization of feces and sewage, the impurities are squeezed and dehydrated, thereby realizing the filter press work of feces and sewage, and then the water supply is stopped, and the moving frame 3 moves toward the adjacent moving frame 3 on the other side thereof and makes them dock with each other to form another group of filter press structures, and the impurities that have been filter-pressed in the original filter press structure naturally fall due to the separation of the two moving frames 3, and at this time, the water supply pipe 5 supplies feces and sewage to the re-formed filter press structure, thereby realizing that one side of the moving frame 3 is filter-pressed while the other side is in the process of discharging filter press impurities, so that the two tasks can be carried out simultaneously to achieve the continuous filter press treatment effect of feces and sewage.

[0022] It should be pointed out here that in the traditional method, when removing filter impurities, multiple filter plates need to be moved one by one, so it can only achieve the one-by-one discharge of filter impurities between two adjacent filter plates. In this case, multiple moving frames 3 move synchronously to achieve the working effect of synchronous impurity removal.

[0023] Furthermore, two sealing plates 7 are provided between two adjacent filter screens 4 on the inner side of the movable frame 3. The two sealing plates 7 respectively seal the two filter screens 4. The sealing plates 7 are slidably installed in the movable frame 3, and the two sealing plates 7 are connected by spring clips 8. The input end of the drain pipe 6 is installed on the movable frame 3 and is located between the two filter screens 4.

[0024] In detail, due to the action of the spring clip 8, in the natural state, the two sealing plates 7 block the two filter screens 4, and the blocking direction is from the inside of the movable frame 3 to the outside, so that when the filter screen 4 on one side of the movable frame 3 is in the filter pressure state, water can pass through the filter screen 4 and push the sealing plate 7 on the filter screen 4 to move, and the spring clip 8 undergoes elastic deformation, and the sealing plate 7 gradually moves to the position of the drain pipe 6 and allows the water passing through the filter screen 4 to smoothly enter the drain pipe 6, while the other filter screen 4 and the sealing plate 7 thereon are in a state of mutual extrusion due to the action of the spring clip 8, and feces and sewage cannot flow to the position of the filter screen 4, thereby preventing feces and sewage from interfering with the impurities that complete the filter pressure.

[0025] It should be pointed out here that in order to avoid the situation where, when the sealing plate 7 moves to the middle position of the input end of the drain pipe 6, one side of the input end of the drain pipe 6 is located on one side of the sealing plate 7, and the other side of the input end of the drain pipe 6 is located on the other side of the sealing plate 7, resulting in water being able to flow on the left and right sides of the sealing plate 7 through the input end of the drain pipe 6, two sealing plates 7 need to be set to achieve complete water blocking and avoid mutual interference between the two working states on the left and right sides of the movable frame 3.

[0026] Furthermore, the surface of the sealing plate 7 facing the filter screen 4 is configured to be conical.

[0027] In detail, when the sealing plate 7 contacts the filter screen 4, the conical surface of the sealing plate 7 can press the filter screen 4 into a cone, so that the filter screen 4 is in an outward convex state on the movable frame 3, which facilitates the removal of impurities on the filter screen 4 after filtering and avoids impurities sticking to the filter screen 4.

[0028] Furthermore, a protrusion 9 is provided on one side wall on the left and right sides of the movable frame 3, and a groove 10 is opened on the other side wall. The water supply pipe 5 passes through the protrusion 9. When two adjacent movable frames 3 are docked, the protrusion 9 on one movable frame 3 is inserted into the groove 10 on the other movable frame 3.

[0029] In detail, by setting the protrusion 9, an installation position can be provided for the water supply pipe 5, so that when the two movable frames 3 are docked, the water supply pipe 5 can smoothly discharge feces and sewage into between the two movable frames 3. The setting of the groove 10 can conveniently provide a storage space for the protrusion 9, thereby facilitating the sealed docking of the two movable frames 3.

[0030] Furthermore, the outer box body 1 is provided with a long ridge 11, a water guide chamber 12 is provided in the long ridge 11, a chute 13 is provided on the side wall of the long ridge 11 facing the inner side of the outer box body 1, the water guide chamber 12 and the chute 13 are connected through a plurality of water holes 14, a plurality of slide plates 15 are slidably provided in the chute 13, and the water supply pipe 5 is connected to the slide plate 15; Among them, when the input end of the water supply pipe 5 is misaligned with the water hole 14, the slide plate 15 blocks the water hole 14. When the input end of the water supply pipe 5 is aligned with the water hole 14, the water supply pipe 5 is connected with the water guide chamber 12, and the water guide chamber 12 is used to supply feces and sewage.

[0031] In detail, the pressurized feces and sewage can be supplied into the water guide chamber 12. When the moving frame 3 is docked with the adjacent moving frame 3 on one side of it, the water supply pipe 5 on one of the two moving frames 3 is aligned and connected with the corresponding water hole 14, and the water supply pipe 5 on the other moving frame 3 is misaligned with the corresponding water hole 14. At this time, the water in the water guide chamber 12 can be supplied into the space between the two moving frames 3 in the docking state through the water hole 14, thereby realizing the water supply work. When the moving frame 3 is docked with the adjacent moving frame 3 on the other side of it, the same method can be used to supply water to the space between the two moving frames 3 in the docking state, thereby realizing the normal water supply work and avoiding the water supply into the space between the two moving frames 3 in the separated state.

[0032] Furthermore, a worm 16 is rotatably arranged inside the outer box body 1, and two worm wheels 17 are meshed on the worm 16. A threaded rod 18 is transmission-arranged on each worm wheel 17. The threaded rod 18 is rotatably installed on the inner wall of the outer box body 1, and a plurality of threaded sleeves 19 are threadedly mounted on the threaded rod 18. One of the two adjacent moving frames 3 is connected to the threaded sleeve 19 on one threaded rod 18, and the other moving frame 3 is connected to the threaded sleeve 19 on the other threaded rod 18. A motor 20 for providing power to the worm 16 is arranged on the outer box body 1.

[0033] In detail, the motor 20 can drive the two threaded rods 18 to move synchronously through the worm 16 and the worm wheel 17, and the threaded sleeves 19 on the two threaded rods 18 move synchronously in the opposite direction, thereby controlling the synchronous opposite movement of the two adjacent moving frames 3, and realizing the staggered docking of the moving frame 3 and the two moving frames 3 on its adjacent sides.

[0034] Furthermore, a water collecting trough plate 21 is provided on the outer box body 1 , and the output end of the drainage pipe 6 passes through the outer box body 1 and is connected to the water collecting trough plate 21 , and a drain pipe 22 is provided at the bottom of the water collecting trough plate 21 .

[0035] In detail, the water after the filter press treatment can be introduced into the water collecting trough plate 21 through the drain pipe 6 and discharged uniformly through the drain pipe 22. When the moving frame 3 moves, the drain pipe 6 can be bent and deformed.

[0036] Furthermore, a material guiding ramp 23 is obliquely arranged at the bottom of the outer box body 1 .

[0037] In detail, the material guide ramp 23 is located below the multiple movable frames 3. When the filtration is completed, two adjacent movable frames 3 are separated, and the impurities naturally fall into the material guide ramp 23 and slide along the material guide ramp 23, thereby achieving unified aggregation of the impurities and facilitating subsequent sorting and removal.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
