Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to raw material drying equipment for producing and processing organic fertilizer. Background Art

[0002] Raw material drying equipment for organic fertilizer production and processing is a mechanical equipment specially used to remove excess moisture from organic fertilizer raw materials. Its core function is to dry high-humidity materials (such as livestock and poultry manure, straw, sludge, etc.) to a suitable moisture content through heat transfer and airflow to meet subsequent processing or storage requirements.

[0003] During the operation of existing raw material drying equipment, when processing wet raw materials, a more prominent problem is faced. Since the wet raw materials themselves are sticky, they are very easy to stick to each other during the drying process. This adhesion phenomenon will cause serious consequences. On the one hand, the raw materials inside the raw material agglomerates are wrapped up and it is difficult to fully contact with the high-temperature air. On the other hand, in order to make the internal raw materials also meet the drying requirements, the drying time can only be extended. However, this not only prolongs the time required for the overall drying, but also greatly reduces the drying efficiency. Based on this, the present invention purposely provides a raw material drying equipment for organic fertilizer production and processing that can prevent raw materials from agglomerating during the drying process and ensure the drying effect.

[0018] Beneficial effects of the present invention:

[0019] 1. In the present invention, the wet raw material circulates between the circulation chamber and the fixed cylinder through the rotation of the feeding auger. The raw material is in a dispersed state when falling from the first outlet. In the process of feeding, the raw material contacts the rising high-temperature air, which makes it easier to exchange heat and facilitates uniform drying. The outlet alternating component closes the first outlet, so that the dry raw material is transported to the crushing component through the feeding auger and crushed into small-particle fertilizer.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0031] See also Figures 1-6 As shown, the present invention is a raw material drying equipment for organic fertilizer production and processing, comprising:

[0032] The frame 1 is fixed with a drying box 2, and a heating chamber 3 and a circulation chamber 201 are provided in the drying box 2. The drying box 2 is provided with a feeding port 14 connected to the circulation chamber 201, and the feeding port 14 is used to fill the raw materials into the circulation chamber 201. The heating chamber 3 surrounds the circulation chamber 201 and is connected to the heating source. The heating chamber 3 is used to heat the circulation chamber 201. The circulation chamber 201 is provided with a monitoring component for monitoring the drying progress of the raw materials. The circulation chamber 2 01 is fixedly installed with a fixed cylinder 4, which passes through the bottom of the drying box 2. The fixed cylinder 4 is provided with a discharge port 402, a circulation port 401 and a first outlet 403 from bottom to top. The discharge port 402 is located below the drying box 2, the circulation port 401 is located at the bottom of the circulation chamber 201, and the first outlet 403 is located at the top of the fixed cylinder 4. A feeding auger 5 is rotatably installed in the frame 1. The feeding auger 5 is driven to rotate by a first driving source, and the edge of the feeding auger 5 is in sliding cooperation with the inner wall of the fixed cylinder 4;

[0033] A crushing assembly, which is disposed in the circulation chamber 201 and is located above the first outlet 403;

[0034] The outlet alternating component is arranged in the frame 1 and is located above the fixed cylinder 4. The outlet alternating component is connected to the monitoring component. The outlet alternating component is used to control the opening and closing of the first outlet 403. When the first outlet 403 is opened, the raw material enters the circulation chamber 201 from the first outlet 403. When the first outlet 403 is closed, the raw material enters the crushing component from the outlet alternating component and then falls into the circulation chamber 201.

[0035] Wherein, the feed port 14 is provided with an openable and closable electromagnetic valve.

[0036] In one case of this embodiment, the first driving source can be a servo motor, a servo motor and other components, and can also be other mechanisms that can realize rotational motion. This embodiment does not make specific limitations here; it should be noted that the heating source of the present invention can be an electric heating wire, and can also be selected by conveying the heated air into the heating chamber 3 for circulation, etc. The monitoring component includes a temperature sensor, a humidity sensor, an online analyzer and a controller, etc. The above components are all existing technologies, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0037] The working principle of the present invention is as follows: first, the wet raw material is filled into the circulation chamber 201 through the feed port 14, and then the heating chamber 3 is heated by the heating source, and the high temperature is transferred to the circulation chamber 201 to dry the wet raw material, and the monitoring component constantly monitors the drying progress of the raw material. When drying is in progress, the outlet alternating component is away from the fixed cylinder 4, such as Figure 2 Taking the example shown, at this time, the first driving source drives the feeding auger 5 to rotate, and the moist raw material in the circulation chamber 201 enters the interior of the fixed cylinder 4 through the circulation port 401, and the feeding auger 5 rotates and cooperates with the inner wall of the fixed cylinder 4, thereby lifting the moist raw material upward to the first outlet 403 and re-flowing into the circulation chamber 201, thereby realizing the effect of circulation drying, and in this circulation process, the raw material is in a dispersed state when it originally falls from the first outlet 403, and is more likely to contact with high-temperature air, which is conducive to uniform drying, and when the feeding auger 5 transports the raw material upward, the cooperation between its edge and the inner wall of the fixed cylinder 4 can also continuously cut the raw material to prevent the raw material from agglomerating, and the moist raw material is dried in this cycle until the monitoring component monitors that the raw material has completed drying;

[0038] Then the outlet alternation component controls the first outlet 403 to be closed. Figure 4As shown in the example, the feeding auger 5 will convey the dry raw materials to the crushing assembly to be crushed into small-particle fertilizers, and the crushing assembly is located in the circulation chamber 201 and above the first outlet 403, which means that the crushing assembly is located at the top of the circulation chamber 201. The crushed small-particle fertilizers are more likely to exchange heat with the high-temperature air during the falling process and are fully dried. After a period of circulation, all the dry raw materials are crushed into small-particle fertilizers. This process can completely avoid the problem of raw materials piling up and not being fully dried inside. Then the first driving source drives the feeding auger 5 to rotate in the opposite direction, and the raw materials in the fixed cylinder 4 and the lifting cylinder 7 are discharged from the discharge port 402, and the raw materials in the circulation chamber 201 also enter through the circulation port 401 and are finally discharged from the discharge port 402, thereby completing the unloading work after drying;

[0039] Of course, if the raw material is prone to sticking and clumping, the threshold of the monitoring component can be adjusted to control the outlet alternation component to open and close the first outlet 403 during the drying process, thereby intermittently breaking up the raw material during drying, ensuring that the raw material does not clumping and affect the drying effect, thereby accelerating the drying speed of the wet raw material.

[0040] In this way, the appropriate drying mode can be adjusted flexibly according to the state of the drying raw materials, so that the raw materials can be dried from the initial whole block to the crushing for secondary drying after drying. Under the premise of avoiding the blockage of the crushing components caused by moist raw materials, it can ensure that the raw materials are crushed into small particles of fertilizer and added to the circulating drying process, avoiding the problem of slowing down the drying progress due to the agglomeration of raw materials and uneven and incomplete drying.

[0041] like Figure 1-Figure 5 As shown, as a preferred embodiment of the present invention, the outlet alternating component includes a lifting cylinder 7 and a second outlet 701, the lifting cylinder 7 is slidably installed in the frame 1, the lifting cylinder 7 is located above the fixed cylinder 4, and the lifting cylinder 7 is driven by an output source to lift and lower, the output source is connected to the monitoring component, and a second outlet 701 is opened at the top of the lifting cylinder 7, the lifting cylinder 7 is coaxially arranged with the fixed cylinder 4, and the edge of the feeding auger 5 slides with the inner wall of the lifting cylinder 7, when the raw material is dried, the output source drives the lifting cylinder 7 to rise away from the fixed cylinder 4, at this time the first outlet 403 is opened, and the raw material enters the circulation chamber 201 from the first outlet 403; when the raw material is dried, the output source drives the lifting cylinder 7 to descend and splice with the fixed cylinder 4, at this time the first outlet 403 is closed, and the raw material enters the crushing component from the second outlet 701.

[0042] In one case of this embodiment, the output source may be an electric cylinder, an electric telescopic rod or other components, or other mechanisms capable of achieving lifting motion, which is not specifically limited in this embodiment.

[0043] In practical application, if Figure 5 As shown in the example, when the lifting cylinder 7 is away from the fixed cylinder 4, the first outlet 403 is opened. At this time, the feeding screw 5 will lift the raw material to the first outlet 403, and the raw material will flow out from the first outlet 403. When the lifting cylinder 7 descends, the bottom of the lifting cylinder 7 will block the first outlet 403. At this time, the inner wall of the lifting cylinder 7 and the edge of the feeding screw 5 cooperate, so that the feeding screw 5 can continue to lift the raw material into the lifting cylinder 7, and finally flow out from the second outlet 701. In this way, the switching of raw material outlets at different heights is realized. When the raw material is relatively humid, , allowing the raw materials to flow in directly from the first outlet 403 without passing through the crushing component. At this time, the wet raw materials are preliminarily dried to avoid the problem that the raw materials with high humidity will stick to the inside of the crushing component after entering the crushing component. After the preliminary drying, the raw materials contain less water and are prone to forming large lumps of raw materials. The viscosity of the raw materials decreases. At this time, the raw materials are allowed to flow out from the second outlet 701 and enter the crushing component. The raw materials are immediately crushed into small particles of fertilizer, so that the raw materials that are not completely dried inside are exposed and thoroughly dried.

[0044] like Figures 1-6 As shown, as a preferred embodiment of the present invention, the outlet alternating assembly also includes a lifting box 6 and a connecting chamber 601. The lifting box 6 is fixedly installed on the outer circular surface of the lifting cylinder 7, and a connecting chamber 601 is opened in the lifting box 6. When the lifting cylinder 7 descends to block the first outlet 403, the connecting chamber 601 is connected with the circulation chamber 201.

[0045] In actual application of this embodiment, in order to prevent the raw materials flowing out of the second outlet 701 from scattering outside the circulation chamber 201, a lifting box 6 is provided. When the lifting cylinder 7 descends to block the first outlet 403, the lifting box 6 will also descend synchronously, and the connecting chamber 601 and the circulation chamber 201 are connected to form a whole chamber, and the second outlet 701 is located in the connecting chamber 601, thereby ensuring that all the raw materials enter the circulation chamber 201.

[0046] like Figures 1-6 As shown, as a preferred embodiment of the present invention, a second drainage platform 12 is fixedly installed in the connecting cavity 601, the second drainage platform 12 is sleeved on the outer surface of the lifting cylinder 7, the second drainage platform 12 is located below the second outlet 701, and the discharge end of the second drainage platform 12 faces the crushing assembly.

[0047] In actual application of this embodiment, since the raw materials will slide along the outer surface of the lifting cylinder 7 after flowing out from the second outlet 701, which may cause them to stick to the outer surface of the lifting cylinder 7, a second guide platform 12 is provided to guide the raw materials into the crushing assembly. On the one hand, this prevents the raw materials from sticking to the outer surface of the lifting cylinder 7, and on the other hand, ensures that all the raw materials can enter the crushing assembly to complete the crushing work.

[0048] like Figure 1-Figure 4 As shown, as a preferred embodiment of the present invention, the crushing assembly includes a crushing box 8 and a crushing roller 9. The crushing box 8 is fixedly installed in the circulation chamber 201, the crushing box 8 is located between the second outlet 701 and the first outlet 403, and the top of the crushing box 8 is a funnel-shaped open arrangement. Two crushing rollers 9 that cooperate with each other are rotatably installed in the crushing box 8, and the discharge end of the second diversion platform 12 faces the crushing box 8.

[0049] In actual application of this embodiment, the raw materials flowing out from the second outlet 701 fall onto the second drainage platform 12 and slide along the second drainage platform 12 into the crushing box 8. The large pieces of raw materials are crushed into small particles of fertilizer by the cooperation of the two crushing rollers 9. On the one hand, it is convenient for unloading. On the other hand, the wet raw materials that are not completely dried in the middle of the large pieces of raw materials are exposed for thorough drying. At this time, the raw materials tend to be dry. When the crushing rollers 9 crush the raw materials, the wet raw materials adhering to the crushing rollers 9 will also gradually dry, and thus be squeezed into powder and fall into the circulation chamber 201, so as to prevent the wet raw materials from clogging the gaps between the crushing rollers 9.

[0050] like Figure 1-Figure 4 As shown, as a preferred embodiment of the present invention, a plurality of staggered inclined plates 10 are provided in the circulation chamber 201, each inclined plate 10 is arranged at an angle, the end of the inclined plate 10 with a higher horizontal height is the feed end, and the end of the inclined plate 10 with a lower horizontal height is the discharge end, the discharge end of the inclined plate 10 is aligned with the feed end of the adjacent inclined plate 10 below it, and the plurality of inclined plates 10 are all located below the first outlet 403.

[0051] In actual application, this embodiment can extend the time for the raw materials to fall in the circulation chamber 201 through the arrangement of multiple inclined plates 10, allowing the raw materials to be in contact with high-temperature air for a longer time in one cycle, thereby improving the overall drying efficiency. The back-and-forth sliding can change the position where the raw materials contact the plate surface, avoiding the problem of poor drying effect caused by one side of the raw materials always being in contact with the plate surface.

[0052] like Figure 1-Figure 4 As shown, as a preferred embodiment of the present invention, the feed end of each inclined plate 10 is rotatably installed in the circulation chamber 201, and the inclined plate 10 is driven to rotate by a second driving source. When the material falls on the inclined plate 10, the second driving source drives the inclined plate 10 to rotate reciprocatingly.

[0053] In one case of this embodiment, the second driving source may be a servo motor, a servo motor or other components, or other mechanisms capable of achieving rotational motion, which is not specifically limited in this embodiment.

[0054] In actual application of this embodiment, when the material slides on the surface of the inclined plate 10, the second driving source drives the inclined plate 10 to rotate back and forth, and does not cause the inclined plate 10 to rotate to a horizontal position. This is equivalent to the inclined plate 10 being able to shake the raw material. During the shaking process, the material will be vacated, thereby constantly changing the contact position with the plate surface, thereby improving the heat exchange efficiency with the high-temperature air, and this effect is more obvious after the raw material is crushed into small granular fertilizer by the crushing assembly.

[0055] like Figures 1-6 As shown, as a preferred embodiment of the present invention, a first guide platform 11 is fixedly installed in the circulation chamber 201, and the first guide platform 11 is sleeved on the outer surface of the fixed cylinder 4. The first guide platform 11 is located below the first outlet 403, and the discharge end of the first guide platform 11 faces the inclined plate 10.

[0056] In practical application, if Figure 2 As shown in the example, after the raw materials flow out from the first outlet 403, they fall onto the first guide platform 11 and slide along the first guide platform 11 to the inclined plate 10, ensuring that the raw materials will not slide along the outer wall of the fixed cylinder 4, ensuring that the raw materials can fall onto the inclined plate 10 and be dried for a long time.

[0057] like Figures 1-6 As shown, as a preferred embodiment of the present invention, the bottom plate of the circulation chamber 201 is set to be an annular conical bottom plate 13, and the distance between the conical bottom plate 13 and the axis of the fixed cylinder 4 increases upward along the axis direction of the fixed cylinder 4.

[0058] In actual application of this embodiment, the raw materials falling to the bottom of the circulation chamber 201 can be guided to the circulation port 401 through the conical bottom plate 13. Whether it is circulation drying or unloading the dried raw materials, the time can be shortened, thereby increasing the time for drying raw material processing.

[0059] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
