Description

Technical Field

[0001] The present application relates to the technical field of crushing and drying, and in particular to a crushing and drying device for compound microbial fertilizer. Background Art

[0002] Compound microbial fertilizer refers to a living microbial product formed by the combination of specific microorganisms and nutrients, which can provide, maintain or improve plant nutrition, increase the yield of agricultural products or improve the quality of agricultural products. Since the production process of compound microbial fertilizer needs to go through the step of "fermentation", the compound microbial fertilizer obtained by compounding has the characteristics of high humidity and high viscosity. During the production process, it is necessary to dry it first to remove the moisture in the compound microbial fertilizer, and then crush the dried compound microbial fertilizer to make the material more delicate for uniform mixing of the material and subsequent processing (such as granulation and coating, etc.).

[0003] However, in the drying and crushing process of the existing compound microbial fertilizer, it is usually dried by blowing hot air through a dryer, and then the dried compound microbial fertilizer is manually transferred to a crusher and crushed by the rotation of the crushing knife. The above drying method may have the phenomenon that the surface of the compound microbial fertilizer accumulated in the drying device is dried while the inside is not completely dried, resulting in poor drying effect of the compound microbial fertilizer. Moreover, the manual transfer of the compound microbial fertilizer causes a waste of manpower and reduces the production efficiency. In the process of cutting the compound microbial fertilizer with larger particles by the rotation of the crushing knife, the compound microbial fertilizer is not extruded, resulting in poor crushing effect of the compound microbial fertilizer. Summary of the Utility Model

[0004] The present application provides a crushing and drying device for compound microbial fertilizer to solve the technical problems recorded in the above background art.

[0005] To solve the above technical problems, the present application adopts the following technical solutions to solve them:

[0011] The bottom end of the second rotating shaft penetrates through the top of the drying furnace body and extends into the drying furnace body. A plurality of the material turning rods are arranged on the shaft body of the second rotating shaft located in the drying furnace body at intervals from top to bottom, and a material turning cone is arranged on the surface of each material turning rod.

[0012] Optionally, the bottom of the crushing box is communicated with a receiving box. A plurality of springs are arranged at equal intervals on the inner bottom surface of the receiving box. The top ends of the plurality of springs are horizontally provided with a mounting frame. A screening net and a mounting plate are sequentially arranged in the mounting frame from outside to inside. A vibration motor is arranged on the lower surface of the mounting plate. A vertical cylinder is arranged on the upper surface of the mounting frame around the screening net;

[0013] Wherein, the length of the spring in the free state, the thickness of the mounting frame, and the height of the vertical cylinder sum up to be less than the height of the receiving box.

[0014] Optionally, a box door is arranged on the receiving box.

[0015] Optionally, a feed inlet is opened on the side wall of the drying furnace body near its top, and a discharge outlet is opened at its bottom.

[0016] Optionally, the feed inlet of the crushing box is opened at its top, and its bottom is communicated with a collecting pipe. A second valve is arranged on the collecting pipe.

[0017] Optionally, a dehumidifying pipe is communicated with the top of the drying furnace body. A stop valve is arranged on the dehumidifying pipe. One end of the dehumidifying pipe away from the drying furnace body is communicated with an induced draft fan.

[0018] The compound microbial fertilizer crushing and drying device provided by the present application dries the compound microbial fertilizer entering it through the drying furnace body. During the drying process, the turning unit continuously turns up the compound microbial fertilizer in the drying furnace body, enabling the compound microbial fertilizer in the drying furnace body to be evenly heated during the drying process, thereby improving the drying efficiency of the compound microbial fertilizer. After the compound microbial fertilizer is completely dried, the first valve is opened, and the dried compound microbial fertilizer in the drying furnace body can flow into the crushing box through the feeding pipeline. This avoids manually transferring the dried compound microbial fertilizer into the crushing box, thus saving manpower and improving the production efficiency of the compound microbial fertilizer. In addition, since the crushing assembly is arranged below the feeding port of the crushing box, the compound microbial fertilizer entering the crushing box from the feeding port of the crushing box will fall onto the two first rotating shafts included in the crushing assembly. The two first rotating shafts are driven to rotate in opposite directions by the first driving members corresponding to each first rotating shaft. During the process of rotating in opposite directions, the two first rotating shafts squeeze the compound microbial fertilizer falling onto them. At the same time, the crushing heads on the two first rotating shafts squeeze and crush the compound microbial fertilizer falling onto the first rotating shafts during the process of rotating in opposite directions with the corresponding first rotating shafts. Therefore, under the action of the first rotating shafts and the crushing heads, the compound microbial fertilizer entering the crushing box is squeezed and crushed as much as possible, thereby improving the crushing efficiency of the compound microbial fertilizer and making the drying and crushing effects of the compound microbial fertilizer better.

Detailed implementation manners

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts also belong to the scope of protection of the present application.

[0028] Reference Figures 1 to 6 , the present application provides a composite microbial fertilizer crushing and drying device, including:

[0029] A drying furnace body 100, in which a material turning unit 200 for turning the composite microbial fertilizer therein is provided; wherein, the composite microbial fertilizer entering the drying furnace body 100 is turned by the material turning unit 200, so that the composite microbial fertilizer can be evenly heated in the drying furnace body 100, thereby avoiding the situation that the surface of the composite microbial fertilizer is over-dried while the inside is not dried in the drying furnace body 100, and then shortening the drying time of the composite microbial fertilizer in the drying furnace body 100 and improving the drying efficiency of the composite microbial fertilizer.

[0030] The crushing box 300, the feeding port of the crushing box 300 is communicated with the discharging port of the drying furnace body 100 through the feeding pipeline 301. A first valve 3011 is arranged on the feeding pipeline 301. A crushing assembly 400 is arranged in the crushing box 300 and is located below its feeding port. Among them, after the compound microbial fertilizer is completely dried in the drying furnace body 100, the first valve 3011 is opened, so that the dried compound microbial fertilizer enters the crushing box 300 through the feeding pipeline 301, and then the compound microbial fertilizer is crushed by the crushing assembly 400 located below the feeding port of the crushing box 300.

[0031] Specifically, the crushing assembly 400 includes two first rotating shafts 401 that are horizontally spaced apart by a preset distance and are rotatably arranged in the crushing box 300. Crushing heads 4011 are arranged on the outer walls of the two first rotating shafts 401 along their lengths. Each first rotating shaft 401 is driven by a driving member 302 arranged on the outer wall of the crushing box 300. Among them, the driving member 302 can be a driving motor. If one of the first rotating shafts 401 rotates forward under the drive of its corresponding driving member 302, and the other first rotating shaft 401 rotates reversely under the drive of its corresponding driving member 302, then the two first rotating shafts 401 rotate in opposite directions. In this way, during the process of the two first rotating shafts 401 rotating in opposite directions, the compound microbial fertilizer falling on them is squeezed, and the crushing heads 4011 on the two first rotating shafts 401 can squeeze and crush the compound microbial fertilizer during the rotation of their corresponding first rotating shafts 401, further improving the crushing efficiency of the compound microbial fertilizer.

[0032] The compound microbial fertilizer crushing and drying device provided by the present application dries the compound microbial fertilizer entering it through the drying furnace body 100. During the drying process, the compound microbial fertilizer in the drying furnace body 100 is continuously turned over by the material turning unit 200, so that the compound microbial fertilizer in the drying furnace body 100 can be evenly heated during the drying process, thereby improving the drying efficiency of the compound microbial fertilizer. After the compound microbial fertilizer is completely dried, the first valve 3011 is opened, and the dried compound microbial fertilizer in the drying furnace body 100 can flow into the crushing box 300 through the feeding pipeline 301. This avoids manually transferring the dried compound microbial fertilizer into the crushing box 300, thus saving manpower and improving the production efficiency of the compound microbial fertilizer. In addition, since the crushing component 400 is arranged below the feeding port of the crushing box 300, the compound microbial fertilizer entering the crushing box 300 from the feeding port of the crushing box 300 will fall onto the two first rotating shafts 401 included in the crushing component 400. The two first rotating shafts 401 are driven to rotate in opposite directions by the driving members 302 corresponding to each first rotating shaft 401. During the opposite rotation of the two first rotating shafts 401, the compound microbial fertilizer falling onto them is extruded, and at the same time, the crushing heads 4011 on the two first rotating shafts 401 extrude and crush the compound microbial fertilizer falling onto the first rotating shafts 401 during the opposite rotation process corresponding to their respective first rotating shafts 401. Thus, under the action of the first rotating shafts 401 and the crushing heads 4011, the compound microbial fertilizer entering the crushing box 300 is extruded and crushed as much as possible, thereby improving the crushing efficiency of the compound microbial fertilizer and making the drying and crushing effects of the compound microbial fertilizer better.

[0033] In some embodiments, referring to Figure 2 , the material turning unit 200 in the present application includes a second rotating shaft 201 and a plurality of material turning rods 202; specifically, the bottom end of the second rotating shaft 201 penetrates through the top of the drying furnace body 100 and extends into the drying furnace body 100. The plurality of material turning rods 202 are arranged at intervals from top to bottom on the shaft body of the second rotating shaft 201 located in the drying furnace body 100, and a material turning cone 2021 is arranged on the surface of each material turning rod 202. Among them, the second rotating shaft 201 is driven by a driving motor, and the output shaft of the driving motor is connected to the top end of the second rotating shaft 201 located outside the drying furnace body 100. The number of the material turning rods 202 and the number of the material turning cones 2021 on each material turning rod 202 can be set according to the actual situation such as the size of the drying furnace body 100. Therefore, the present application does not make specific limitations on them here.

[0034] In the above embodiments, during the rotation of the second rotating shaft 201, multiple turning rods 202 rotate synchronously with the second rotating shaft 201. During the rotation of the turning rods 202, the turning cones 2021 thereon are driven to rotate. During the rotation of the turning rods 202 and the turning cones 2021, the compound microbial fertilizer in the drying furnace body 100 can be turned over, and the caked or piled compound microbial fertilizer can be broken up, thereby improving the drying efficiency of the compound microbial fertilizer in the drying furnace body 100.

[0035] In some embodiments, referring to Figure 1 、 Figure 4 、 Figure 5 and Figure 6 , a receiving box 303 is connected to the bottom of the crushing box 300 in this application. A plurality of springs 3031 are equidistantly arranged on the inner bottom surface of the receiving box 303. An installation frame 500 is horizontally arranged at the top ends of the plurality of springs 3031. A screening net 501 and a mounting plate 502 are sequentially arranged in the installation frame 500 from outside to inside. A vibration motor 5021 is arranged on the lower surface of the mounting plate 502. A vertical cylinder 503 is arranged around the screening net 501 on the upper surface of the installation frame 500; wherein, the size of the receiving box 303 is larger than that of the crushing box 300, which is convenient for installing components such as the installation frame 500 and the springs 3031. During the actual screening process of the compound microbial fertilizer, the vibration motor 5021 is turned on, and the compound microbial fertilizer crushed by the crushing assembly 400 in the crushing box 300 falls onto the screening net 501, and the vibration motor 5021 drives the installation frame 500 and the screening net 501 fixed in the installation frame 500 to vibrate, thereby achieving the purpose of screening the crushed compound microbial fertilizer. The setting of the vertical cylinder 503 plays a role in gathering the crushed compound microbial fertilizer, so that all the crushed compound microbial fertilizer can pass through the screening, which is convenient for subsequent granulation, etc. The setting of the springs 3031 ensures the vibration amplitude of the screening net 501 and guarantees the screening effect of the compound microbial fertilizer.

[0036] Among them, the sum of the length of the spring 3031 in the free state, the thickness of the installation frame 500, and the height of the vertical cylinder 503 is less than the height of the receiving box 303, which can ensure that the screening net 501 has enough space to vibrate under the vibration of the vibration motor 5021, improving the screening effect of the crushed compound microbial fertilizer.

[0037] In some embodiments, referring to Figure 1 , a box door 3032 is arranged on the receiving box 303 in this application. Among them, the setting of the box door 3032 is convenient for opening it to install, clean, disassemble, etc. the screening net 501, thereby improving the portability of the installation and disassembly of the screening net 501 and ensuring the screening efficiency of the screening net 501.

[0038] In some embodiments, referring to Figure 1 a feed pipe communicating with the side wall near the top of the drying furnace body 100 in the present application is provided with a feed port 101, and a discharge port 102 is provided at its bottom. Among them, a screw conveyor can be arranged in the feed pipe to improve the feeding efficiency.

[0039] In the above embodiment, the compound microbial fertilizer entering the drying furnace body 100 from the feed port 101 of the drying furnace body 100 is dried and then discharged through the discharge port 102 at the bottom of the drying furnace body 100. The arrangement of the discharge port 102 at the bottom of the drying furnace body 100 enables the dried compound microbial fertilizer in the drying furnace body 100 to be completely discharged out of the drying furnace body 100 as much as possible, improving the discharging efficiency.

[0040] In some embodiments, referring to Figure 1 a feed port of the crushing box 300 in the present application is opened at its top, and a collecting pipe 304 is connected to its bottom. A second valve 3041 is arranged on the collecting pipe 304. Among them, the feed port of the crushing box 300 and the discharge port of the drying furnace body 100 are arranged vertically, so that the dried compound microbial fertilizer in the drying furnace body 100 can quickly enter the crushing box 300 through the discharge port 102 of the drying furnace body 100, the conveying pipe 301 and the feed port of the crushing box 300 under the action of gravity, improving the feeding efficiency. After the compound microbial fertilizer in the crushing box 300 is crushed, the second valve 3041 is opened, and the crushed compound microbial fertilizer can be discharged out of the crushing box 300 through the collecting pipe 304.

[0041] In some embodiments, referring to Figure 1 a dehumidifying pipe 103 is connected to the top of the drying furnace body 100 in the present application. A stop valve 1031 is arranged on the dehumidifying pipe 103, and an induced draft fan 1032 is connected to the end of the dehumidifying pipe 103 far from the drying furnace body 100.

[0042] In the above embodiment, since the production process of the compound microbial fertilizer needs to go through the step of "fermentation", the compound microbial fertilizer prepared by compounding has the characteristics of high humidity and high viscosity. Therefore, a certain amount of water vapor and the like will be generated during the drying process of the compound microbial fertilizer in the drying furnace body 100. In order to prevent the water vapor from condensing and contacting the compound microbial fertilizer to cause the compound microbial fertilizer to agglomerate, the induced draft fan 1032 and the stop valve 1031 are opened, so that the water vapor in the drying furnace body 100 is discharged out of the drying furnace body 100 through the dehumidifying pipe 103, ensuring the drying efficiency of the compound microbial fertilizer.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
