Description

Technical Field

[0001] The utility model relates to the technical field of dung drying, in particular to a cow dung drying device. Background Art

[0002] With the rapid development of the cattle industry, the manure problem in cattle farms needs to be taken seriously. Many cattle farms lack centralized treatment of cow dung, resulting in cow dung being piled up everywhere. Especially in the summer in the south, the stench emitted by the centralized piles of cow dung not only affects the normal life of surrounding residents, but cow dung is also the source of breeding and reproduction of a variety of bacterial pathogens, and can play a role in the spread of parasite eggs and pathogenic microorganisms. There are many uses for dry cow dung. Dry cow dung mainly contains 10-20% crude protein, 1-3% crude fat, 20-30% nitrogen-free extract and 15-30% crude fiber, so cow dung has high nutrients. Fermented cow dung can become high-quality organic fertilizer products, which can loosen the soil, improve soil compaction, chelate trace elements in the soil, and improve soil fertility. To process organic fertilizer using cow dung, the dung must first be dried in the sun or drained to keep its moisture content below 85%. Farmers basically dry their dung naturally, which takes a long time and causes greater pollution. It is mainly affected by the weather. At the same time, cow dung has different shapes. Blocky cow dung is not easy to dry. After drying, it is also blocky, not fluffy enough, and has low utilization value.

[0003] At present, in order to centrally process manure, existing beef cattle farms usually use cow dung dryers to dry the cow dung, and then transport it to nearby farmers or mix it with other auxiliary materials to make bio-fertilizer to facilitate the growth of crops. This not only solves the problem of manure polluting the environment, but also promotes the growth of crops.

[0004] After searching, it was found that the Chinese patent with patent number CN202120445878.1 discloses a device suitable for drying cow dung, including a cow dung drying box, a hot air supply box, an air inlet, an exhaust duct, a feeding port, an equipment switch, a cow dung drying box observation window, an upper maintenance window, a main maintenance window, a power interface and a dry cow dung conveyor belt. The upper surface of the cow dung drying box is welded and connected to the hot air supply box. During drying, the heated air is continuously transported to the inside of the cow dung drying box to discharge the water vapor inside the equipment and accelerate the drying of the cow dung. A through hole is opened on the front surface of the hot air supply box to install the air inlet, a through hole is opened on the top of the hot air supply box to install the exhaust duct, a rectangular through hole is opened on the front of the cow dung drying box to install the feeding port, and more than two through holes of different specifications are opened on the surface of one side of the cow dung drying box to respectively install the cow dung drying box observation window, upper maintenance window, main maintenance window and power interface. The cow dung can be dried and then transported to various places for fertilizing fruit trees or cultivating mushrooms.

[0005] However, through the analysis of the above technical solution, it is inconvenient to stir the cow dung when drying, so only the surface of the cow dung can be dried, and the internal water content of the cow dung is still high, which is not convenient for subsequent production of biofertilizer or transportation. Utility Model Content

[0006] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a cow dung drying device, which can not only stir the cow dung through the stirring mechanism inside the drying cylinder to ensure the uniformity of drying, but also realize the transportation of cow dung, so as to realize automatic drying, effectively improve the drying efficiency, and reduce the tedious steps of manual operation.

[0007] The utility model is realized by constructing a cow dung drying device, comprising a drying cylinder, in which a stirring mechanism for turning and conveying the material is arranged;

[0008] An air inlet pipe is arranged at the top of the drying drum and is used to spray high-temperature gas into the drying drum;

[0009] The discharge cylinder is arranged at one end of the drying cylinder and is connected with the drying cylinder. A discharge port is arranged on the outer side of the discharge cylinder. The stirring mechanism extends into the discharge cylinder and turns the internal material to the discharge port for discharge.

[0010] Specifically, the drying cylinder is horizontally supported by a bracket, and the drying cylinder includes a lower cylinder and an upper cylinder. The air inlet pipe is arranged on the upper cylinder, and a breathable mesh plate for uniformly conveying the high-temperature gas discharged from the air inlet pipe to the drying cylinder is also arranged inside the upper cylinder.

[0011] Specifically, the lower cylinder, the upper cylinder and the air-permeable mesh plate are all semicircular plates, and there is a gap between the air-permeable mesh plate and the upper cylinder.

[0012] Specifically, the end of the drying cylinder away from the discharge cylinder is also connected to a feed hopper.

[0013] Specifically, the stirring mechanism includes a rotating shaft and a spiral blade arranged at the outer end of the rotating shaft. The rotating shaft is rotatably installed in the drying cylinder and keeps one end inserted into the discharge cylinder, and the other end extends to the outside of the drying cylinder and is connected to an external transmission mechanism. The spiral blade is installed on the outer end of the rotating shaft in the drying cylinder and keeps the outer end of the spiral blade close to the inner bottom of the lower cylinder.

[0014] Specifically, a discharge roller is arranged on the outer end of the rotating shaft inside the discharge barrel, and a plurality of discharge plates close to the inner wall of the discharge barrel are arranged on the outer end of the discharge roller. The discharge plates flip the material in the discharge barrel upward to the discharge port for discharge as the rotating shaft rotates.

[0015] The utility model has the following beneficial effects:

[0016] The drying device can facilitate the stirring and transportation of cow dung by arranging a stirring mechanism inside the drying cylinder, and is combined with an air inlet pipe above the drying cylinder to facilitate drying of the cow dung, which not only ensures the uniformity of drying, but also facilitates the automatic drying of the cow dung.

[0017] The drying device can automatically discharge the cow dung transported and dried in the drying cylinder by arranging a discharge cylinder at the end of the drying cylinder and a stirring mechanism extending into the interior of the discharge cylinder, thereby realizing automatic drying of the cow dung.

Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0027] As described in the background technology, the manure produced in existing farms is naturally dried through air, which not only has low drying efficiency and high pollution, but also easily becomes compacted, affecting the subsequent production of bio-fertilizer. Some drying devices are not convenient for stirring and drying cow dung, and the uniformity of drying cannot be guaranteed.

[0028] Based on the above reasons, the utility model provides a cow dung drying device, including a drying cylinder, in which a stirring mechanism for turning and conveying the material is arranged;

[0029] The air inlet pipe 5 is arranged at the top of the drying drum and is used to inject high-temperature gas into the drying drum;

[0030] The discharge cylinder 6 is arranged at one end of the drying cylinder and is connected to the drying cylinder. A discharge port 7 is arranged on the outer side of the discharge cylinder 6. The stirring mechanism extends into the discharge cylinder 6 and turns the internal material to the discharge port 7 for discharge.

[0031] Specifically, the drying cylinder is horizontally supported by a bracket 1, and the drying cylinder includes a lower cylinder 3 and an upper cylinder 4. The air inlet pipe 5 is arranged on the upper cylinder 4, and a breathable mesh plate 8 is also arranged inside the upper cylinder 4 for uniformly transporting the high-temperature gas discharged from the air inlet pipe 5 to the drying cylinder.

[0032] By the attached Figure 1 or attached Figure 5 It can be seen that, specifically, the lower cylinder 3, the upper cylinder 4 and the air-permeable mesh plate 8 are all semicircular plates, and there is a gap between the air-permeable mesh plate 8 and the upper cylinder 4. A connecting plate can be provided at the connecting portion of the lower cylinder and the upper cylinder, and the two cylinders are fixed together by the connecting plate and fasteners. The air-permeable mesh plate can be installed on the inner end of the connecting plate of the upper cylinder by fasteners, while ensuring that the air-permeable mesh plate is adapted to the size of the lower cylinder, so as to facilitate the installation of the air-permeable mesh plate without affecting the rotation of the stirring mechanism.

[0033] Please see attached Figure 5 Specifically, the end of the drying cylinder away from the discharge cylinder 6 is also connected to the feed hopper 2, and the end of the drying cylinder close to the feed hopper is sealed to prevent cow dung from flowing backward after entering the drying cylinder from the feed hopper.

[0034] Please continue to refer to the attached Figure 5Specifically, the stirring mechanism includes a rotating shaft 9 and a spiral blade 10 arranged at the outer end of the rotating shaft 9. The rotating shaft 9 is rotatably installed in the drying cylinder and keeps one end inserted into the discharge cylinder 6, and the other end extends to the outside of the drying cylinder and is connected to the external transmission mechanism. The spiral blade 10 is installed on the outer end of the rotating shaft 9 in the drying cylinder and keeps the outer end of the spiral blade 10 close to the inner bottom of the lower cylinder 3.

[0035] Specifically, a discharge roller 11 is arranged on the outer end of the rotating shaft 9 inside the discharge barrel 6, and a plurality of discharge plates 12 close to the inner wall of the discharge barrel 6 are arranged on the outer end of the discharge roller 11. The discharge plates 12 flip the material in the discharge barrel 6 upward to the discharge port 7 for discharge as the rotating shaft 9 rotates.

[0036] When the drying device is in use, high-temperature gas is first delivered to the air inlet pipe 5 through an external steam delivery system, and then the high-temperature gas enters the upper cylinder 4 and contacts the air-permeable mesh plate 8. A part of the gas passes through the mesh holes of the air-permeable mesh plate 8, while the remaining gas is blocked and diffuses to the surroundings until it passes through the mesh holes of the air-permeable mesh plate 8 and contacts the lower cylinder 3. Then, the rotating shaft 9 is driven to rotate through an external transmission mechanism (such as a driving motor and a belt transmission mechanism), thereby driving the spiral blades 10, the discharge drum 11 and the discharge plate 12 to rotate, and then cow dung is put into the drying cylinder through the feed hopper 2. After the cow dung enters the drying cylinder, it turns upward and moves toward the discharge cylinder 6 under the rotation of the spiral blades 10. During the turning and movement of the cow dung, it contacts the high-temperature gas in the drying cylinder to generate heat exchange, thereby realizing the drying of the cow dung. When the cow dung moves into the discharge cylinder 6, it is pushed to the discharge port 7 under the rotation of the discharge plate 12 and discharged, and the internal gas is discharged from the discharge port 7 together with the cow dung, thereby realizing the automatic drying process of the cow dung.

[0037] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
