DETAILED DESCRIPTION

[0072] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0073] like Figures 1 to 13 As shown, the livestock and poultry manure drying treatment equipment of the present invention includes a bracket 1, a screen cage 2, a conveyor belt group 3, a cleaning component 4, a drying component 5 and a top cover 6.

[0074] like Figure 1 , Figure 4 and Figure 6 As shown, two sieve cages 2 are arranged on the bracket 1, and the two sieve cages 2 are rotatably connected to the bracket 1; a conveyor belt group 3 is arranged on the bracket 1, and both ends of the conveyor belt group 3 are respectively located in a sieve cage 2, and the conveyor belt group 3 can rotate along the axis of the sieve cage 2; a cleaning component 4 is arranged on the bracket 1, and the cleaning component 4 corresponds to the mesh of the sieve cage 2, and the cleaning component 4 is used for air supply or water spray; a drying component 5 is arranged on the conveyor belt group 3;

[0075] As in the above structure, the bracket 1 is used to support two screen cages 2 so that the two screen cages 2 can rotate, and the conveyor belt group 3 is arranged between the two screen cages 2 to convey livestock and poultry manure from one screen cage 2 to another screen cage 2;

[0076] In the specific operation, the livestock and poultry manure is first filtered through the belt filter press equipment to perform preliminary drying, and then the preliminary dried manure is transported to one of the screen cages 2 through the conveyor belt, and is initially screened by the screen cage 2. As the screen cage 2 rotates, part of the debris is screened out and the manure is dispersed;

[0077] When the screen cage 2 is screening, the belt surface of the conveyor belt group 3 is in a vertical state, so that one of the narrow sides of the conveyor belt group 3 is facing upward to prevent feces and dirt from accumulating on the conveyor belt group 3. When the initial dispersion is completed, the conveyor belt group 3 is leveled so that the conveyor belt surface faces upward. At this time, as the screen cage 2 rotates, the dispersed feces and dirt will fall onto the conveyor belt group 3.

[0078] As the conveyor belt group 3 is conveyed, the manure on the conveyor belt group 3 is further dried by the drying assembly 5, and then falls into another screen cage 2. At this time, the dried manure is screened twice by the screen cage 2 to remove the debris; finally, another conveyor belt is connected, and the conveyor belt is extended to the screen cage 2. The screen cage 2 drives the dried manure to fall onto the conveyor belt, so that the dried manure is output from the screen cage 2;

[0079] The livestock and poultry manure drying treatment equipment of the present invention can perform multiple screening and filtering treatments on manure and simultaneously complete the drying work, is suitable for belt filter press equipment, and has a compact structure and high efficiency.

[0080] like Figure 7 and Figure 8 As shown, the bracket 1 includes a base frame 11, a support plate 12 and a support wheel 13, and the screen cage 2 includes a mesh cage 21, a support tube 22 and a baffle 23, wherein four support plates 12 are arranged in parallel in the base frame 11, and the four support plates 12 are rotatably provided with support wheels 13; support tubes 22 are coaxially arranged at both ends of the mesh cage 21, and the support tubes 22 abut against the support wheel 13; a plurality of baffles 23 are arranged on the inner wall of the mesh cage 21, and the baffles 23 are arranged obliquely; the support wheel 13 is connected to a power assembly;

[0081] As in the above structure, four support plates 12 are arranged in parallel in the base frame 11 for installing the support wheel 13, thereby realizing the installation of the screen cage 2;

[0082] When assembling the screen cage 2, it is overlapped to the support wheel 13 through the support pipes 22 on both sides of the mesh cage 21, so that the screen cage 2 can rotate;

[0083] The power assembly connected to the support wheel 13 is a direct drive motor, or a sprocket transmission group driven by a motor;

[0084] When the support wheel 13 drives the screen cage 2 to rotate, the baffle 23 in the mesh cage 21 will move the feces and sewage, achieving continuous lifting and falling. At this time, the debris will leak out through the mesh holes of the mesh cage 21, thereby completing the dispersion and filtration of the feces and sewage; at the same time, the baffle 23 will also lift the feces and sewage to facilitate transportation to the conveyor belt group 3.

[0085] like Figure 2 As shown, the bottom frame 11 is provided with an output port 101, and the output port 101 is used to arrange a hopper or a conveyor belt to collect the filtered debris or directly output the debris through the conveyor belt.

[0086] In some embodiments, a gear ring may be provided on the screen cage 2, and the screen cage 2 may be driven to rotate by a gear transmission structure.

[0087] like Figure 8 and Fig. 9 As shown, the screen cage 2 further includes a support ring 24, and the cleaning assembly 4 includes a slip ring 41, a first arc plate 42, a pipeline 43 and a connecting rod 44, wherein two support rings 24 are provided, and the support ring 24 is located at the connection between the screen cage 21 and the support pipe 22; the slip ring 41 is an arc-shaped structure, and the slip ring 41 and the support ring 24 are slidably matched; the first arc plate 42 is provided on both slip rings 41; the pipeline 43 is connected to the two first arc plates 42; the connecting rod 44 is connected to the two slip rings 41, and is connected to the support plate 12;

[0088] As in the above structure, in order to ensure the cleanliness of the screen cage 2 so that the screen cage 21 can perform screening work normally, a cleaning component 4 needs to be set to clean it;

[0089] Specifically, in the cleaning assembly 4, the slip ring 41 is connected and fixed to the support plate 12 through a connecting rod 44, and a first arc plate 42 is installed on the slip ring 41 for connecting a pipe 43, so that air supply or water spraying can be performed through the pipe 43 to blow or spray water to clean the mesh cage 21 of the screen cage 2 to avoid mesh blockage affecting filtering and screening;

[0090] Specifically, two slip rings 41 and two first arc plates 42 are provided, and a slot is provided on the first arc plate 42. When laying the pipe 43, the end of the pipe 43 can be clamped to the slot of the first arc plate 42. The pipes 43 can be staggered into two groups, and an arc-shaped manifold is provided on the side of the first arc plate 42. Among the two groups of pipes, one group is used for air supply and the other group is used for water spraying.

[0091] At the same time, a support ring 24 is provided on the screen cage 2, which is used to cooperate with the slip ring 41 of the cleaning assembly 4. After the slip ring 41 is fixed to the support plate 12, the slip ring 41 will limit the support ring 24, so as to cooperate with the support wheel 13 of the bracket 1 to complete the positioning of the screen cage 2, so that the installation and operation of the screen cage 2 are stable.

[0092] like Figure 4 , Fig.10 , Fig.12 and Fig.13 As shown, the conveyor belt group 3 includes a connecting frame 31, a connecting plate 32, a ring plate 33 and a conveyor belt 34, wherein the connecting frame 31 is located between the two screen cages 2, the end of the connecting frame 31 extends into the two screen cages 2, and the connecting frame 31 is connected to two adjacent support plates 12 through the connecting plate 32; two ring plates 33 are arranged on the connecting frame 31, the ring plates 33 are coaxial with the screen cage 2, and a through hole 301 is arranged at the position where the ring plates 33 are connected to the connecting frame 31; the conveyor belt 34 is rotatably connected to the ring plates 33 and extends into the two mesh cages 21;

[0093] As in the above structure, the connecting frame 31 of the conveyor belt group 3 is the main supporting part, and the connecting frame 31 is connected to the adjacent support plate 12 through the connecting plate 32 to achieve the fixing of the conveyor belt group 3;

[0094] The conveyor belt 34 is used for conveying manure and sewage. In order to support the rotation of the conveyor belt 34, a ring plate 33 is provided on the connecting frame 31, and the conveyor belt 34 is rotatably connected with the ring plate 33, so that the conveyor belt 34 can rotate along the ring plate 33, so that the conveyor belt 34 can be switched between horizontal and vertical placement; this structure can prevent manure and sewage from being accumulated on the conveyor belt group 3 when the screen cage 2 is screening;

[0095] In this structure, the end of the connecting frame 31 of the conveyor belt group 3 extends into the screen cage 2, and a through hole 301 is provided at the position where the ring plate 33 is connected to the connecting frame 31;

[0096] Specifically, the connecting frame 31 is configured as a semicircular plate structure, so that the connecting frame 31 and the conveyor belt 34 can be cleaned from above, and water and dirt can flow out to both sides through the through hole 301 to enter the two screen cages 2, which has the advantage of easy cleaning.

[0097] like Fig.12 and Fig.13 As shown, the conveyor belt assembly 3 further includes a driving wheel 35 and a side plate 36, wherein the driving wheel 35 is arranged on both sides of the conveyor belt 34, the driving wheel 35 abuts against the ring plate 33, and the driving wheel 35 is connected to a power assembly; the side plate 36 is an angular structure, and the side plate 36 is arranged on both sides of the conveyor belt 34;

[0098] As in the above structure, the driving wheel 35 cooperates with the ring plate 33, and the power assembly connected to the driving wheel 35 adopts a direct drive motor. In this way, under the drive of the direct drive motor, the driving wheel 35 will drive the conveyor belt 34 to rotate along the ring plate 33 to achieve a 90-degree angle switch;

[0099] In some embodiments, the driving wheel 35 and the ring plate 33 cooperate with each other and are replaced by a gear ring structure.

[0100] like Fig.13 In the structure shown, the conveyor belt group 3 is in a longitudinal structure, and one of the narrow sides of the conveyor belt 34 is facing upward, so as to prevent the sieve cage 2 from driving the feces to fall onto the conveyor belt 34 when dispersing;

[0101] When it is necessary to transport manure, Fig.12 As shown, the conveyor belt 34 is laid flat, and after the sieve cage 2 lifts the feces through the baffle 23, it falls onto the conveyor belt 34 for transportation;

[0102] Furthermore, in order to reduce the accumulation of feces and dirt on the conveyor belt group 3, an angular side plate 36 is provided on the narrow side of the conveyor belt 34 so that the feces and dirt that fall onto the conveyor belt group 3 can slide off to avoid accumulation and prevent affecting the normal operation of the conveyor belt group 3.

[0103] like Figure 4 As shown, one end of the conveyor belt 34 extends and occupies more than one-half of the axial length of the mesh cylinder 21; the other end of the conveyor belt 34 extends and occupies less than one-half of the axial length of another mesh cylinder 21;

[0104] As in the above structure, a longer conveyor belt 34 is arranged in one of the mesh cages 21, so that when the feces and sewage in the screen cage 2 need to be transported, it can better receive the feces and sewage; and a shorter conveyor belt 34 is accommodated in the other mesh cage 21, so that the conveyor belt 34 can transport the feces and sewage into the mesh cage 21 to prevent the feces and sewage from being sent to the outside of the mesh cage 21; at the same time, this also facilitates the external conveyor belt 34 to transport the feces and sewage out through the mesh cage 21.

[0105] like Fig.11 As shown, the drying assembly 5 includes a second arc plate 51, a heating tube 52 and an ultraviolet lamp 53, wherein one second arc plate 51 is provided on each of the two ring plates 33 that are relatively far away from each other, and the second arc plate 51 extends into the support tube 22; the heating tube 52 is provided on the inner side of one of the second arc plates 51; and the ultraviolet lamp 53 is provided on the inner side of the other second arc plate 51;

[0107] Specifically, after one of the sieve cages 2 has screened and filtered the relatively wet feces, the conveyor belt 34 is used for transportation. At this time, the heating tube 52 on one of the second arc plates 51 will dry the feces, and the ultraviolet lamp 53 on the other second arc plate 51 will disinfect the feces to eliminate pathogens and insect eggs, thereby ensuring the safety of subsequent feces utilization.

[0108] In some embodiments, heating tubes 52 and ultraviolet lamps 53 are disposed on the two second arc plates 51 .
